1、 Equipment name: automatic bottle blowing machine

2、 Specification and model: hdn-880b

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

During the Second World War, blow molding technology began to be used to produce LDPE vials. In the late 1950s, with the birth of HDPE and the development of blow molding machine, blow molding technology has been widely used. The volume of the hollow container can reach thousands of liters, and some production has been controlled by computer. The plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. the hollow containers are widely used as industrial packaging containers. According to the production method of parison, blow molding can be divided into extrusion blow molding and injection blow molding. The extrusion process is to extrude the plasticized plastic into the extrusion die head through the screw, and then cooperate with the mold below and the compressed gas to realize the product molding. The extrusion blow molding process consists of five steps:

1. The plasticized raw materials are made into plastic embryo;

2. Part of the mold embryo was cut off by closing the mold;

3. Filling gas into the mold cavity to form the mold embryo and cool it;

4. Open the mold and take out the formed container;

5. Trim the flash to get the finished product. 　

5. Operation steps:

1. The bottle embryo is placed in the bottle embryo container and automatically enters the bottle embryo positioning device through the conveying device.

2. The bottle embryo is automatically loaded into the bottle embryo fixator with the mouth upward, and then sent into the drying channel.

3. After heating, the bottle embryo is sent to the blowing and drawing platform, and then the mold is locked, successively through low-pressure blowing and drawing, high-pressure blowing and drawing, exhaust, and finally the mold is opened.

4. The bottle is taken down from the bottle blowing platform by the automatic demoulding system.

6、 Production process:

1、 Preheating:

In order to keep the shape of the bottle mouth, the bottle mouth does not need to be heated, so a certain cooling device is needed to cool it.

2、Blow molding:

In this stage, the preform (embryo) which has been preheated is placed in the blow mould which has been made, and the preform (embryo) is blown into the required bottle by high pressure inflation. The bottle blowing machines on the market are generally divided into full-automatic and semi-automatic. The automatic bottle blowing machine combines the two operations of bottle blowing through the operation of the manipulator, eliminating the process of putting the preheated bottle blank (embryo) into the blowing mold manually. The speed of production has been greatly accelerated, of course, the price is higher than that of semi-automatic.

7、 Machine features:

1. It has the advantages of large clamping force, no expanding die, less force, no wear and long service life.

2. The sealing flying out technology is adopted to make the sealing and wide mouth bottle mouth sealing easier without deformation.

3. PLC computer control, touch screen display, easy to operate, reliable, high stability.

8、 Maintenance:

1. No feeding at the feeding level: several situations need to be checked:

If there is no material in the hopper, if it is, it is necessary to add the material as soon as possible; No: please check whether the control contactor of the elevator is in the power on state, if it is in the power on state, check whether the motor is in the power on and load state as soon as possible, because this situation is likely to be caused by the bottle blank (embryo) blocking the lifting belt, at this time, the easiest way is to manually help the lifting. If the control contactor of the elevator is not in the power on state, please check whether the battery embryo detection eye is not in the same line with the reflector.

2. Feeding old card feeding plate:

This situation is a headache. Empirically, if the length of the bottle blank (embryo) is longer and the cutting weight is larger, then this phenomenon is relatively small.

3. The bottle cannot be taken out of the mould after blowing:

First of all, the mold should be opened and closed manually. If it is normal, run it in the idle running state, if it is also normal. Please check your exhaust time setting. If the exhaust setting is normal and the failure occurs every time you blow the bottle, it can be judged that it is the problem of the exhaust valve. Open the exhaust valve to check the condition of its spring and seal (another phenomenon of this failure is that the exhaust sound is loud or there is an unclean exhaust sound). If you encounter the situation that many molds can't be opened by chance during normal production, please check whether the locking pin has some screws in it. In addition, please check whether the clamping force is too large. If it is too large, it should be readjusted according to the standard.

4. Bottle always pinched:

Whether the position of the manipulator is misplaced.

5. Two robots collide:

This situation requires manual reset of the manipulator, which is caused by dislocations.

1. The system equipment is entitled to one-year free warranty, the warranty date is calculated from the date of product acceptance, and the consumable filter material is not listed here.
2. In case of any equipment quality problem (except caused by misoperation or unforeseen factors) during the warranty period, the supplier shall repair it free of charge and replace the damaged parts.
3. After the expiration of the warranty period, only a certain material fee and appropriate technical service fee will be charged.
4. In case of system operation failure which cannot be solved by itself or by telephones, our technical maintenance personnel shall make solutions (including temporary measures) and schedule within 24 hours after receiving the written notice from the demander and report to the competent leaders of both parties.
5. After the delivery of the equipment, our company will have engineers to pay a return visit to understand the operation of the equipment and provide technical services in a timely manner. Users are welcome to ask any technical questions, and we will reply in time.
