Description

Technical Field

[0001] The present invention relates to the technical field of preform processing, and particularly to an automatic preform loading machine with high working efficiency. Background Art

[0002] With the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely applied. The volume of hollow containers can reach thousands of liters, and some production has adopted computer control. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, and polyester, etc. The resulting hollow containers are widely used as industrial packaging containers. According to the method of making preforms, blow molding can be divided into extrusion blow molding and injection blow molding. Newly developed ones include multi-layer blow molding and stretch blow molding. The extrusion process is to extrude the plasticized plastic through a screw into an extrusion blow mold head, and then cooperate with the following mold and compressed gas to realize the molding of the product. The extrusion blow molding process consists of 5 steps: 1. Making the plasticized raw material into a plastic preform; 2. Intercepting a part of the preform and cutting the preform by closing the mold; 3. Filling the mold cavity with gas to form the preform and cooling it; 4. Opening the mold and taking out the formed container; 5. Trimming the flash to obtain the finished product.

[0003] At present, the vast majority of blow molding factories still use manual labor to continuously load preforms beside the machine. Because the production cycle of the blow molding machine generally takes 4 - 5 seconds to complete once, and the preforms, as its processing objects, need to be continuously replenished. Therefore, if the operator needs to meet the full-efficiency production of the blow molding machine, he must also work continuously. This labor intensity is too high, greatly reducing the production efficiency. It cannot achieve convenient and efficient preform feeding, cannot achieve the purpose of facilitating the use by production personnel, and once the personnel leave, the efficiency of the machine will decrease. In addition, long-term work of personnel on the blow molding machine is also prone to safety hazards. The degree of automation is low, and it cannot achieve reducing the operation of production personnel to achieve the purpose of automatic preform loading, thus bringing great inconvenience to the production of the blow molding machine.

[0015] (III) Advantageous Effects

[0016] The present invention provides an automatic embryo loading machine with high working efficiency. Compared with the prior art, it has the following

[0017] advantageous effects:

[0018] (1) For the automatic embryo loading machine with high working efficiency, a first stepping motor is fixedly connected inside the chassis, and a first pulley is fixedly connected to the outer surface of the output shaft of the first stepping motor. Then, through the cooperation of the divider, the second pulley, the material storage bin assembly, the second stepping motor, the lead screw, the threaded block, the embryo dividing cylinder, the bottle embryo bottom supporting cylinder, the embryo supporting frame, the upper embryo mechanism, the embryo picking mechanism, the large turntable, the round rod, the small turntable, the upper embryo cylinder, the blocking cylinder, the upper embryo buffer slideway, the guiding frame and the embryo picking cylinder, it can be realized that the automatic equipment can well replace manual embryo loading and can achieve the purpose of continuous and uninterrupted embryo loading. In this automatic embryo loading machine, the bottle embryos are manually put into the material bin of the embryo loading machine all at once, and then the operator can leave. The equipment automatically completes putting each bottle embryo onto the blow molding machine. Generally, it takes 40 - 60 minutes for the blow molding machine to consume the materials on the embryo loading machine. That is to say, the manual feeding only needs to replenish the materials again after 40 minutes, which greatly reduces the labor force. And for the situation that at least one person must be configured for each blow molding machine in the past, now several blow molding machines can be configured with automatic embryo loading machines at the same time, and only one person is needed to complete the work of replenishing the materials. In this way, the labor force is greatly reduced, and the production cost is reduced. In addition, the action cycle of the embryo loading machine can be completely synchronized with the cycle of the blow molding machine. Therefore, the production efficiency can also be greatly improved. There is no need for production personnel to continuously load embryos, which greatly reduces the labor intensity, improves the production efficiency well, realizes convenient and efficient bottle embryo loading, and well achieves the purpose of facilitating the use of production personnel. Only a few machine maintenance personnel need to guard at intervals to complete continuous and uninterrupted embryo loading production, thus well avoiding the situation that production personnel are prone to safety hazards when working on the blow molding machine for a long time, greatly improving the automation degree of bottle embryo loading production, realizing the reduction of the operation of production personnel to achieve the purpose of automatic embryo loading, and thus greatly facilitating the production of the blow molding machine.

[0019] (2) The automatic blank loading machine with high working efficiency is fixed with a front guard plate on the front of the chassis through screws, and a side guard plate is fixed on one side of the chassis through screws. Then, a protective cover adapted to the blank picking mechanism is fixedly connected to the top of the vertical frame, which can achieve good protection for the entire blank loading equipment, avoid damage caused by external collisions to the equipment, and prevent the situation where normal blank loading production cannot be carried out, thus ensuring the normal operation of the blank loading equipment.

[0020] (3) The automatic blank loading machine with high working efficiency is rotatably connected with rollers through support frames on the top of the bottom plate and around the divider, which can achieve good support for the storage bin assembly. At the same time, the outer surface of the roller is in rolling connection with the bottom of the large turntable of the storage bin assembly, which can greatly reduce the friction between the roller and the large turntable, thus achieving both ensuring the stability of the rotation of the storage bin assembly and not causing too much obstruction to the rotational movement of the storage bin assembly.
