Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bottle processing technology, specifically to a uniform feeding device for plastic bottle processing. Background Technology
[0002] Plastic bottles, as an important form of packaging, are widely used in beverages, food, pharmaceuticals, personal care products, and many other fields. Before the advent of plastic bottles, packaging containers mainly used materials such as glass, metal, and ceramics. Glass bottles dominated the packaging of beverages and pharmaceuticals due to their good sealing properties and chemical stability. However, glass bottles had disadvantages such as being heavy, fragile, and costly. Until the 1960s, the manufacturing technology of PET bottles gradually matured and began to be used on a large scale for soft drink packaging. Due to their lightweight, durability, and cost-effectiveness, PET bottles quickly replaced traditional glass bottles and metal cans.
[0003] Although traditional plastic bottle feeding is automated, manual inspection is still required to prevent empty bottles from being fed into the container. Furthermore, the automatic feeding device will place the bottle preform with the bottle neck facing upwards, but subsequent blow molding requires the bottle neck to face downwards, necessitating an additional process to flip the preform. This not only takes up a lot of space but also significantly reduces the feeding speed of the preform. Therefore, in order to solve the above problems, a uniform feeding device for plastic bottle processing preforms is designed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a uniform feeding device for plastic bottle processing to solve the technical problem of poor efficiency and effect of traditional devices.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform feeding device for plastic bottle processing, comprising a main body, an internal storage groove, a first conveyor belt cooperating with the storage groove, a guide block cooperating with the first conveyor belt on one side of the main body, a clamping block cooperating with the guide block on the main body, a transmission belt installed on the opposite side of the guide block and the clamping block, a transmission device installed at the ends of the guide block and the clamping block, a longitudinally rotating second conveyor belt installed on the transmission device, and a plurality of gripping clamps cooperating with the corresponding clamping blocks connected to the second conveyor belt, and a plurality of partitions installed on the first conveyor belt.
[0006] By adopting the above technical solution, the preform is poured into the storage tank of the main body. As the first conveyor belt starts, the preform is continuously transported up. The preforms transported to the top roll along the guide block to the gap between the clamping block and the guide block. Since the diameter of the preform's mouth is relatively wide, the preform will fall into the gap between the clamping block and the guide block with the mouth facing upward. As the conveyor belt rotates, it moves the preform to the end of the clamping block. At this time, as the second conveyor belt rotates, the gripper clamps the corresponding preform and moves it upward and flips it in the opposite direction.
[0007] The present invention is further configured such that a baffle that cooperates with the clamping block is installed on the guide block.
[0008] By adopting the above technical solution, the baffle is used to intercept the preform that falls into the gap between the clamping block and the guide block if it does not fall upwards according to the predetermined bottle opening orientation.
[0009] The present invention is further configured such that a driving device is installed inside the main body, and the output end of the driving device is connected to the clamping block, wherein the driving device is a hydraulic structure.
[0010] By adopting the above technical solution, the drive device can adjust the gap between the clamping block and the guide block to adapt to preforms of different sizes.
[0011] The present invention is further configured such that a third conveyor belt cooperating with the second conveyor belt is installed on the transmission device, and a plurality of limiting blocks are connected on the third conveyor belt, and the limiting blocks and the gripping clamp cooperate with each other without interfering with each other, and a rotating motor cooperating with the third conveyor belt and the second conveyor belt is installed inside the transmission device.
[0012] By adopting the above technical solution, the preform after being flipped will detach from the corresponding gripper and fall onto the corresponding limit block. Then, with the operation of the third conveyor belt on the transmission device, it will be transported to the subsequent processing flow.
[0013] In summary, the present invention has the following main advantages:
[0014] This invention achieves a regular arrangement of preforms through the cooperation between the clamping block and the guide block. Then, the preforms with the bottle mouth facing upwards are flipped by the second conveyor belt to achieve uniform feeding of the preforms. During this process, there will be no phenomenon of preforms falling into the air, and the area occupied is small. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0021] The embodiments of this utility model will be described below based on its overall structure.
[0022] A preform feeding device for plastic bottle processing at a constant speed, such as Figure 1-4 As shown, the device includes a main body 1, with a storage slot 2 inside. A first conveyor belt 3, which mates with the storage slot 2, is installed inside the main body 1. A guide block 6, which mates with the first conveyor belt 3, is located on one side of the main body 1. A clamping block 7, which mates with the guide block 6, is located on the main body 1. A transmission belt is installed on the opposite side of both the guide block 6 and the clamping block 7. A transmission device 11 is installed at the ends of the guide block 6 and the clamping block 7, and a longitudinally rotating second conveyor belt 4 is installed on the transmission device 11. Several gripping clamps, which mate with the corresponding clamping blocks 7, are connected to the second conveyor belt 4. 9. Several partitions are installed on the first conveyor belt 3 to pour the preforms into the storage tank 2 of the main body 1. As the first conveyor belt 3 starts, it continuously transports the preforms up. The preforms transported to the top roll along the guide block 6 to the gap between the clamping block 7 and the guide block 6. Since the diameter of the preform's mouth is relatively wide, the preform will fall into the gap between the clamping block 7 and the guide block 6 with the mouth facing upward. As the conveyor belt rotates, it moves the preform to the end of the clamping block 7. At this time, as the second conveyor belt 4 rotates, the gripper 9 clamps the corresponding preform and moves it upward and flips it in the opposite direction.
[0023] A baffle 12 is installed on the guide block 6 to cooperate with the clamping block 7. The baffle 12 is used to intercept the bottle from falling into the gap between the clamping block 7 and the guide block 6 if it does not fall upward according to the predetermined bottle opening orientation.
[0024] The main body 1 is equipped with a drive device 8, and the output end of the drive device 8 is connected to the clamping block 7. The drive device 8 is a hydraulic structure. The gap between the clamping block 7 and the guide block 6 can be adjusted according to the drive device 8 to adapt to preforms of different sizes.
[0025] The transmission device 11 is equipped with a third conveyor belt 5 that cooperates with the second conveyor belt 4, and a number of limiting blocks 10 are connected to the third conveyor belt 5. The limiting blocks 10 and the gripping clamps 9 cooperate with each other without interfering with each other. The transmission device 11 is equipped with a rotating motor that cooperates with the third conveyor belt 5 and the second conveyor belt 4. After being flipped, the bottle preform will be released from the corresponding gripping clamps 9 and fall into the corresponding limiting block 10. As the third conveyor belt 5 on the transmission device 11 rotates, it will be transported to the subsequent processing flow.
[0026] Working principle: Bottle preforms are poured into the storage tank 2 of the main body 1. With the start of the first conveyor belt 3, bottle preforms are continuously transported upwards. The bottle preforms at the top roll along the guide block 6 to the gap between the clamping block 7 and the guide block 6. Since the bottle mouth diameter is relatively wide, the bottle preform falls into the gap between the clamping block 7 and the guide block 6 with the bottle mouth facing upwards. With the operation of the transmission belt, the bottle preform is moved to the end of the clamping block 7. During this period, the drive device 8 can adjust the gap between the clamping block 7 and the guide block 6 to accommodate bottle preforms of different sizes. In addition, the baffle 12 can intercept bottle preforms that do not fall into the gap between the clamping block 7 and the guide block 6 with the bottle mouth facing upwards according to the predetermined direction. Then, with the operation of the second conveyor belt 4, the gripper 9 clamps the corresponding bottle preform and moves it upwards and flips it. After flipping, the bottle preform will be released from the corresponding gripper 9 and fall onto the corresponding limit block 10. With the operation of the third conveyor belt 5 on the transmission device 11, it is transported to the subsequent processing process.
