Description

A feeding device for plastic bottle processing Technical Field

[0001] This utility model relates to the field of plastic bottle processing technology, specifically a feeding device for plastic bottle processing. Background Technology

[0002] Plastic bottle processing is the process of turning plastic raw materials into containers with specific shapes and functions through a series of processes. Commonly used raw materials include polyethylene and polyethylene terephthalate. In production, blow molding is the mainstream process. First, the plastic is heated and melted and extruded into a tubular preform. After being placed in a mold, it is inflated by compressed air to fit the inner wall of the mold. After cooling and solidification, the bottle body is formed. Injection molding first injects the raw material into the mold cavity and then cools and solidifies to obtain the bottle body. It is often used to manufacture bottle caps with high precision requirements. In addition, post-processing processes such as printing, labeling, and threading of the bottle neck are required to give the plastic bottle an aesthetic appearance and practical function. Due to its advantages such as light weight, unbreakability, and low cost, the finished plastic bottles are widely used in the food and beverage, daily chemical, and pharmaceutical industries.

[0003] Existing feeding devices used in plastic bottle processing often have fixed structures that make disassembly and cleaning difficult. Furthermore, the devices are prone to shaking when subjected to pressure, which may damage the bottles inside. This not only affects the efficiency of equipment cleaning and maintenance and production hygiene standards, but also increases the risk of bottle breakage, reduces product yield, and affects the continuity of the production line due to insufficient structural stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Referring to Figures 1 to 4, in this embodiment of the present invention, a feeding device for processing plastic bottles includes: a feeding tray 1 and a feeding tray 2. Both the feeding tray 1 and the feeding tray 2 have elastic movable structures 3 on their sides. Springs 32 are fixedly connected to both the upper and lower ends of the elastic movable structures 3. A movable block 33 is fixedly connected between the two sets of springs 32. A fixed block 34 is fixedly connected to the side of the movable block 33. Connecting rods 41 are fixedly connected below the fixed block 34 on the side of the feeding tray 1 and above the fixed block 34 on the side of the feeding tray 2. A connecting sleeve rod 42 is screwed between the two sets of connecting rods 41. A rotating shaft 43 is installed in the middle section of the connecting sleeve rod 42. During the operation of the device, the elastic movable structure 3 can play a role in real time. When the device is under pressure, the spring 32 achieves relative buffering between the feeding plate 1 and the unloading plate 2 through compression and rebound, avoiding rigid collision between the two and causing the device to shake, thereby effectively preventing damage to the internal plastic bottles. The screw connection between the connecting sleeve rod 42 and the connecting rod 41 greatly facilitates the maintenance of the device. Operators can easily disassemble the connecting sleeve rod 42, separate the feeding plate 1 and the unloading plate 2, and thoroughly clean the internal components of the device.

[0023] The feeding tray 1 is equipped with an upper rotating disk 51. After the speed-regulating motor is started, it drives the upper rotating disk 51 to rotate through the transmission connection. The rotation of the upper rotating disk 51 causes the plastic bottles placed in the feeding tray 1 to move accordingly. A guide plate 17 is fixedly connected to the inside of the feeding tray 1 above the discharge spring tube 52. Under the guidance of the guide plate 17, the plastic bottles smoothly enter the discharge spring tube 52 fixed below. The discharge spring tube 52 is made of multiple layers of elastic materials, which have good flexibility and cushioning performance. It can effectively reduce the impact of collision during the entry and sliding of the plastic bottles and prevent damage to the plastic bottles. At the same time, the spiral guide strip inside can guide the plastic bottles to slide down along a fixed trajectory to avoid jamming and accumulation, and ensure smooth feeding.

[0024] The feeding tray 2 is equipped with a lower rotating disk 53. The speed-regulating motor drives the lower rotating disk 53 to rotate synchronously. Multiple sets of slots 54 are evenly opened on the outer side of the lower rotating disk 53. When the plastic bottle slides down from the feeding spring tube 52 to the feeding tray 2, the slots 54 on the outer side of the lower rotating disk 53 will rotate to the corresponding positions in sequence to accurately lock the plastic bottle that is sliding down. As the lower rotating disk 53 continues to rotate, the plastic bottle is transported to the side opening of the feeding tray 2.

[0025] A feeding guide plate 18 is fixedly connected to the inner side of the opening on the side of the feeding tray 2, and a feeding port 19 is fixedly connected to the outer side. The two work together with the lower rotating disk 53. Under the combined action of the feeding guide plate 18 and the feeding port 19, the plastic bottles leave the feeding device quickly and orderly according to the predetermined path and direction, and enter the subsequent processing stage, realizing the efficient operation of the entire feeding process. The design of the guide plate 17, the feeding guide plate 18 and the feeding port 19 optimizes each link from the plastic bottle entering the feeding device to the output, so that the plastic bottles can leave the feeding device quickly and orderly and enter the subsequent processing stage.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The working principle of this utility model is as follows: The operator first screws the connecting sleeve rod 42 to the connecting rod 41 on the side of the feeding tray 1 and the unloading tray 2, checks the connection of the spring 32, the movable block 33 and the fixed block 34 in the elastic movable structure 3 to ensure that the elastic movable structure is normal, and sets the appropriate speed parameters through the speed control motor control panel according to the specifications of the plastic bottle to be processed and the requirements of subsequent equipment. Then, the plastic bottle to be processed is placed in the feeding tray 1, the speed control motor is started to drive the upper rotating disk 51 to rotate, the plastic bottle moves under the drive of the upper rotating disk 51 and moves to the unloading spring tube 52 located below the upper rotating disk 51 under the guidance of the guide plate 17 on the inner side of the feeding tray 1. After entering the unloading spring tube 52, its multi-layer elastic material nested structure The internal spiral guide bar acts as a buffer, guiding the plastic bottle down along a fixed trajectory to the feeding tray 2. At this time, the speed-regulating motor synchronously drives the lower rotating disk 53 to rotate. The slots 54 on the outer side of the lower rotating disk 53 rotate in sequence to catch the plastic bottle that is sliding down and transport it to the side opening of the feeding tray 2. Finally, under the combined action of the feeding guide plate 18 on the inner side and the feeding port 19 on the outer side of the side opening of the feeding tray 2, the plastic bottle leaves the feeding device according to the predetermined path and direction and enters the subsequent processing stage. When the device needs to be cleaned and maintained, the operator loosens the threaded connection between the connecting sleeve rod 42 and the connecting rod 41, disassembles the feeding tray 1 and the feeding tray 2, and thoroughly cleans all the internal components of the device. After cleaning, it is reassembled and ready for the next use.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
