Description

Technical Field

[0001] This utility model relates to a preform sorting machine that can reduce damage to preforms. Background Technology

[0002] With the continuous development of preform production technology, the preform sorting machine, as an indispensable piece of equipment in the preform production process, plays a crucial role in straightening, organizing, and recycling preforms. Typically, a certain number of preforms accumulate in the preform sorting machine hopper. Through the action of the preform breaking unit, these preforms are broken up and fall through specific holes into a recycling belt, which then returns them to the feeding hopper for further processing. During this process, the recycling belt serves to transport the preforms and buffer them from falling, reducing damage.

[0003] However, there is a high risk of collision during the process of returning preforms to the feeding hopper via the recycling belt. When there are a large number of preforms in the hopper, they are subjected to strong force from the preform breaking unit and are broken up. Due to the violent collisions between preforms and other preforms, and between preforms and the conveyor device during the recycling process, preforms are prone to mutual collisions, friction, and even falling during the recycling belt transport, resulting in damage or breakage. Such preform damage not only affects production efficiency but also leads to the scrapping of a large number of preforms, resulting in production losses and resource waste.

[0004] Therefore, existing preform recovery machines lack effective protection and cushioning measures during the preform recycling process, and cannot effectively reduce damage caused by preform collisions. Utility Model Content

[0005] The purpose of this invention is to provide a preform sorting machine that can reduce preform damage, thereby reducing collisions and damage between preforms during the preform recycling process and avoiding unnecessary scrap losses.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A preform handling machine that reduces preform damage includes:

[0008] A preform hopper is used to hold bottle preforms;

[0009] The first preform-returning group is set up inside the preform-collecting hopper and is used to return the bottle preforms.

[0010] A second preform-beating group is set inside the preform-sorting hopper and is used to return the bottle preforms returned by the first preform-beating group.

[0011] A preform recycling port is located behind the second preform group and is used to recycle the returned preforms.

[0012] A billet-scraping motor is located on one side of the billet-scraping hopper and is used to drive the second billet-beating group;

[0013] A synchronous belt is used to link the first and second billet-making groups.

[0014] Preferably, the first billet-beating group is located on the inlet side of the billet hopper, and the second billet-beating group is located on the outlet side of the billet hopper.

[0015] Preferably, the preform recycling holes are located on both sides behind the second preform group.

[0016] Preferably, a recycling belt is provided below the preform recycling hole to receive preforms falling from the preform recycling hole.

[0017] Preferably, a recycling motor for driving the recycling belt is provided on one side of the recycling belt, and a recycling hopper is provided on the outlet side of the recycling belt.

[0018] Preferably, the first blanking group includes a blanking shaft and blanking blades mounted on the blanking shaft, and the second blanking group has the same structure as the first blanking group.

[0019] Preferably, the billet hopper is arranged in an inwardly inclined, concave inverted trapezoidal shape, and the billet-beating blades are trapezoidal blades that cooperate with the billet hopper.

[0020] The beneficial effects of this utility model are:

[0021] The newly added second preformer-forming group and the improved material flow design effectively reduce collisions and friction of preforms during the recycling process. After the preforms pass through the first preformer-forming group, only some of the unformed preforms continue to move downwards. These preforms are further formed by the second preformer-forming group, and the broken-up preforms fall into the recycling conveyor belt through the side holes. This avoids a large number of preforms colliding and falling on the recycling conveyor belt, significantly reducing damage and waste of preforms.

[0022] By setting up a second preformer-forming group, the screening and recycling of preforms are more efficient. Unsorted preforms can be captured and broken up at appropriate locations, reducing the number of preforms that need to be recycled and improving the overall efficiency of the recycling system. With the addition of the second preformer-forming group, the preform sorting process is more uniform, effectively separating unsorted preforms and avoiding blockages and incomplete processing caused by excessive accumulation of preforms in the preformer-forming hopper. This ensures the quality of the preforms and the smooth operation of the production line. Attached Figure Description

[0028] Example

[0029] See Figure 1-2 As shown, a preform handling machine that can reduce preform damage includes:

[0030] 1. A blank hopper for holding bottle preforms;

[0031] A first preform-beating group 2 is set inside the preform-sorting hopper 1 and is used to beat the bottle preforms back;

[0032] A second preform-beating group 3 is set inside the preform-sorting hopper 1 and is used to beat back the bottle preforms beaten back by the first preform-beating group 2.

[0033] A preform recycling hole 4 is located behind the second preform group 3 and is used to recycle the returned preforms.

[0034] A billet-scraping motor 5 is located on one side of the billet-scraping hopper 1 and is used to drive the second billet-beating group 3;

[0035] A synchronous belt 6 is used to link the first billet-making group 2 and the second billet-making group 3.

[0036] By setting up first and second preformer-beating groups 3, the preforms are subjected to more precise control during the sorting and return processes. Under the action of the first preformer-beating group 2, the preforms are effectively broken up, and only those that are not completely sorted will enter the second preformer-beating group 3. This design can avoid excessive collisions and friction on the preforms during the recycling process, thereby significantly reducing the damage rate and scrap rate of the preforms and reducing waste in the production process.

[0037] The second preformer group 3 can further optimize the preform processing effect based on the first preformer group 2. Preforms that are not fully processed will be further processed by the second preformer group 3 and recycled through the recycling hole. This effectively sorts out the preforms that need to be recycled, avoids excessive accumulation of preforms, ensures the flowability and processing efficiency of preforms, and improves the continuity and stability of the entire production process.

[0038] The inclusion of a recycling port for recovering returned preforms effectively guides the dispersed preforms smoothly into the recycling system, preventing blockages or other flow problems caused by poor design during the recycling process. The synchronous belt 6, linking the first and second preform-forming groups 3, ensures that the preforms remain stable and uniform throughout the processing, thereby improving the overall efficiency of the preform recycling system.

[0039] The synchronous belt 6 links the first preform-beating group 2 and the second preform-beating group 3, ensuring coordination between the two groups during operation and avoiding damage to the preforms or uneven processing caused by incoordination between the groups. This design keeps the working rhythm of the two preform-beating groups consistent, improving the overall system stability and reducing the failure rate.

[0040] By reducing preform damage, improving recycling efficiency, and optimizing the processing flow, resource waste during production can be effectively reduced, minimizing scrap costs and resource waste caused by preform damage, thereby lowering overall production costs. Simultaneously, a stable production process also helps improve production efficiency, further saving human and material resources.

[0041] The first preform-beating group 2 is located on the inlet side of the preform hopper 1, the second preform-beating group 3 is located on the outlet side of the preform hopper 1, and the preform recovery hole 4 is located on both sides behind the second preform-beating group 3.

[0042] When the preforms first enter the preform feeding hopper 1, the first preform breaking group 2 initially sorts and breaks them up, removing any clumping or irregular distribution, allowing them to flow evenly to the subsequent processing area. This step lays the foundation for subsequent processing, preventing collisions and damage caused by uneven packing. The second preform breaking group 3 is located on the outlet side, meaning that after the initial sorting by the first group 2, the preforms can undergo further fine-tuning and sorting in the second group 3. This design effectively ensures the final sorting of the preforms, preventing problems or waste caused by incompletely sorted preforms during the recycling process.

[0043] This layout allows the recovery holes to collect returned preforms promptly after they pass through the second preformation group 3. The dual-sided recovery hole design not only increases recovery efficiency but also reduces the residence time of preforms in the preformation hopper 1. Preforms can be quickly and orderly recovered into the recycling system, avoiding prolonged residence in the hopper and reducing damage caused by friction and collision. The first preformation group 2 and the second preformation group 3 are located on the inlet and outlet sides of the hopper, respectively, allowing them to cooperate in processing preforms and preventing excessive collisions or stagnation during the preformation process, maintaining preform flowability. The recovery holes are located on both sides behind the second preformation group 3, helping to ensure smooth preform flow, reducing equipment malfunctions caused by preform accumulation or blockage, and improving the stability and safety of the production line.

[0044] Below the preform recycling hole 4, a recycling belt 7 is provided for receiving preforms falling from the preform recycling hole 4; a recycling motor 8 for driving the recycling belt 7 is provided on one side of the recycling belt 7, and a recycling hopper 9 is provided on the outlet side of the recycling belt 7.

[0045] The recycling belt 7 enables bottle preforms falling from the preform collection hole 4 to be quickly and continuously collected and transported to the recycling hopper 9. This automated conveying method reduces manual intervention, avoids preform accumulation or stagnation, and improves the efficiency and speed of preform recycling. Driven by a motor, the recycling belt 7 can continuously and stably transport the preforms from the collection hole to the recycling hopper 9, effectively preventing preforms from falling or accumulating unevenly during the recycling process, thus ensuring the smooth progress of the recycling process.

[0046] The design of the recycling belt 7 helps to achieve a smooth conveying process, preventing bottle preforms from being damaged due to excessively violent collisions or irregular conveying. Since the bottle preforms are directly conveyed to the recycling hopper 9 via the recycling belt 7, the external force on the bottle preforms during the entire recycling process is reduced, thereby effectively reducing the risk of damage and improving the quality of recycling. With the automation function of the belt driven by the recycling motor 8, the bottle preforms can be recycled into the hopper in a timely manner, avoiding interference from manual or other non-systematic factors, thereby improving the recycling rate.

[0047] By incorporating the recycling belt system 7 and recycling hopper 9, the preform recycling process on the production line has become more automated and centralized. The recycling hopper 9 can hold more preforms, reducing the need for frequent cleaning and manual intervention, making the production line more efficient and continuous. The design of the recycling system simplifies the preform recycling process, allowing operators to focus more on other production stages, reducing equipment downtime or preform waste caused by improper recycling, and also facilitating later maintenance and management.

[0048] The first blanking group 2 includes a blanking shaft 21 and blanking blades 22 mounted on the blanking shaft 21. The second blanking group 3 has the same structure as the first blanking group 2. The blanking hopper 1 is arranged in an inwardly inclined and concave inverted trapezoidal shape. The blanking blades 22 are trapezoidal blades that cooperate with the blanking hopper 1.

[0049] The first preform-beating group 2 and the second preform-beating group 3 have identical structures, ensuring consistency and coordination throughout the preform-beating process. The cooperation of the two preform-beating groups helps the preforms, after entering the preform-sorting hopper 1, to undergo initial sorting by the first group and then fine dispersal by the second group, ensuring even distribution, reducing accumulation, and improving the efficiency of the entire sorting process. The preform-beating blades 22 are designed to fit the shape of the inverted trapezoidal preform-sorting hopper 1, effectively contacting and propelling the preforms along the hopper. This design allows the preform-beating blades 22 to better guide the movement of the preforms during operation, ensuring uniform force on the preforms during sorting, thereby reducing collisions and damage and improving the sorting effect.

[0050] The preform hopper 1 features an inverted trapezoidal shape with an inward tilt, which facilitates the natural flow of preforms. The tilt angle guides the preforms downwards more easily, preventing accumulation or blockage within the hopper and ensuring continuous material flow. This design reduces the time preforms remain in the hopper, lowers the risk of blockage, and improves production efficiency. The trapezoidal design of the preform-beating blades 22 matches the shape of the inverted trapezoidal hopper, minimizing preform friction and resistance and promoting uniform distribution and flow. This not only improves preform handling but also prevents damage or jamming due to excessive friction within the hopper.

[0051] The identical design of the first and second preform-making groups 3 ensures stable operation throughout the preform-making process at different stages. The coordination between the two groups significantly reduces instability caused by differing structural designs, thereby lowering the frequency of equipment failures. The well-coordinated design of the inverted trapezoidal preform-feeding hopper 1 and the trapezoidal preform-making blades 22 allows preforms to pass smoothly through the hopper system and be uniformly dispersed, reducing equipment failures and downtime caused by preform accumulation, jamming, or uneven processing. This simplifies equipment maintenance and improves the overall stability of the production line.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
