Description

Technical Field

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

[0002] In the production of plastic pulleys, plastic gear shafts are core transmission components. Their stable and continuous feeding is directly related to the efficiency of the production line and the quality of the finished product, and is a key link to ensure the smooth operation of automated production. Such shafts need to achieve precise delivery in high-speed and high-precision production scenarios, which puts forward strict requirements on the continuity, synchronization and impact resistance of the feeding device.

[0003] However, existing feeding devices for plastic pulley production generally suffer from structural shortcomings: First, their continuous feeding capacity is weak. Traditional devices often experience material interruptions or accumulation due to mismatched material transfer rhythms, failing to meet the continuous and uniform conveying requirements of plastic gear shafts. Second, the drive system design is crude, making it difficult to achieve precise synchronization between the conveyor belt and the feeding action, resulting in disordered material conveying rhythms and affecting the overall coordination of the production line. Third, they lack effective impact resistance and anti-deviation design. When plastic gear shafts are transferred between the storage box and the conveyor belt, they are prone to positional displacement or mechanical wear due to impacts, reducing equipment operational stability and shortening service life. These problems not only restrict the improvement of production efficiency but also increase enterprise operating costs due to frequent downtime for adjustments, becoming the core bottleneck for the efficient manufacturing of plastic pulleys. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a feeding device for the production of plastic pulleys, so as to solve the core technical problems in the prior art, such as the weak continuous feeding capacity of plastic gear shafts, the asynchronous drive of conveyor belt and feeding action leading to disordered material conveying rhythm, and the lack of impact resistance and anti-deviation design causing shaft position deviation and mechanical wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for producing plastic pulleys, comprising a base plate, a first mounting frame and a second mounting frame provided on the base plate, a support frame provided on the second mounting frame, a storage frame for storing plastic gear shafts provided on the support frame, a discharge port provided on the storage frame, a mounting plate provided at the bottom of the storage frame, and a conveyor belt for conveying plastic gear shafts provided on the first mounting frame, the conveyor belt being located beside the storage frame; The storage box is provided with an adjustment component for adjusting the feeding of the plastic gear shaft. The adjustment component includes a movable plate that slides in the mounting plate, and a toggle block is provided at the top of the movable plate. As the movable plate slides back and forth in the mounting plate, the actuating block pushes the plastic gear shaft in the storage box to slide onto the conveyor belt. Preferably, the storage box is provided with an arc-shaped plate for guiding the flow of the plastic gear shaft; The mounting plate has a sliding groove for the sliding block to slide, and the sliding block is arranged in a fan shape. Preferably, the conveyor belt is fitted with two inclined baffles, which are symmetrically arranged at the top of the conveyor belt. A guide platform is provided between the conveyor belt and the storage box. The guide platform is inclined and the inner wall of the guide platform is provided with a soft pad. Preferably, the adjustment assembly includes a first connecting frame disposed at the top of the support frame, a connecting plate rotatably disposed in the first connecting frame, a mounting plate disposed on the connecting plate, the top of the connecting plate being fixedly connected to the bottom of the movable plate, and the bottom of the movable plate being fixedly fixed. The mounting plate is located along the length of the connecting plate and is located in the lower half of the connecting plate; When the connecting plate swings, the movable plate slides back and forth in the mounting plate; Preferably, the adjustment assembly includes a fixed plate disposed on a support frame, a mounting rod rotatably disposed in the fixed plate, and a cam plate fixed to one end of the mounting rod; After the cam plate rotates, it comes into contact with the mounting plate. Preferably, the adjustment assembly includes a first fixing frame disposed outside the second connecting frame, a second fixing frame disposed at the bottom end of the mounting plate, and a connecting spring disposed between the first fixing frame and the second fixing frame; When the cam plate is in contact with the mounting plate, the connecting spring is in a stretched state; When the cam plate loses contact with the mounting plate, the connecting spring is in a retracted state; Preferably, a servo motor is provided on the base plate, and a first pulley is provided on the output shaft of the servo motor and the transmission shaft of the conveyor belt, and a first belt is connected to the two first pulleys for transmission. The drive shaft of the conveyor belt and the outside of the mounting rod are both equipped with second pulleys, and the two second pulleys are connected to a second belt for transmission. When the servo motor is in drive mode, the first pulley rotates, and under the transmission of the first belt, the drive shaft of the conveyor belt rotates. The mounting rod rotates under the transmission of the second pulley and the second belt.

[0006] In summary, the present invention has the following main advantages: 1. This utility model uses a servo motor to synchronously drive the conveyor belt and mounting rod to rotate. Combined with the abutment transmission mechanism of the cam plate and the connecting plate, it realizes the reciprocating sliding of the movable plate to push materials. With the elastic reset function of the connecting spring, the movable plate is pulled back when the cam is disengaged, forming a "push-return" cycle action. This ensures the continuous and stable conveying of the plastic gear shaft from the storage box to the conveyor belt, reduces the risk of material feeding interruption, and improves production efficiency and equipment operation reliability.

[0007] 2. The actuating block in this utility model adopts a fan-shaped design, and is in a non-pushing contact state with the material during the return stroke, effectively avoiding jamming; the inclined setting of the guide table and the soft pad on the inner wall reduce the impact of the material sliding down, and together with the symmetrical inclined baffle to prevent deviation, the three work together to reduce the mechanical wear and positional deviation risk during the material conveying process, ensure the smoothness of feeding and extend the service life of the equipment, and form a functional complement with the feeding stability, jointly enhancing the reliability of the production process.

[0011] The embodiments of this utility model will be described below based on its overall structure.

[0012] Example Please see Figures 1-7 This utility model provides a technical solution: a feeding device for producing plastic pulleys, including a base plate 1, a first mounting frame 11 and a second mounting frame 21 on the base plate 1, a support frame 22 on the second mounting frame 21, a storage frame 23 for storing plastic gear shafts on the support frame 22, a discharge port 233 on the storage frame 23, a mounting plate 232 at the bottom of the storage frame 23, and a conveyor belt 12 for conveying plastic gear shafts on the first mounting frame 11, the conveyor belt 12 being located beside the storage frame 23; The storage box 23 is equipped with an adjustment component 4 for adjusting the feeding of the plastic gear shaft. The adjustment component 4 includes a movable plate 463 that slides in the mounting plate 232. The top of the movable plate 463 is provided with a toggle block 464. When the movable plate 463 slides back and forth in the mounting plate 232, the toggle block 464 pushes the plastic gear shaft in the storage box 23 onto the conveyor belt 12. The sliding of the movable plate 463 in conjunction with the toggle block 464 achieves precise material feeding, and the reciprocating sliding mechanism ensures continuous feeding. Furthermore, the storage box 23 is provided with an arc-shaped plate 231 for guiding the flow of the plastic gear shaft; the mounting plate 232 is provided with a sliding groove for the sliding of the actuating block 464, and the actuating block 464 is arranged in a fan shape; the arc-shaped plate 231 guides the flow to reduce the risk of material jamming, and the sliding groove design of the fan-shaped actuating block 464 is adapted to the sliding trajectory to improve the smoothness of pushing. Furthermore, two inclined baffles 121 are inserted into the conveyor belt 12, and the two inclined baffles 121 are symmetrically arranged at the top of the conveyor belt 12. A guide platform 122 is arranged between the conveyor belt 12 and the storage box 23. The guide platform 122 is inclined, and the inner wall of the guide platform 122 is provided with a soft pad 123. The symmetrical inclined baffles 121 prevent material deviation, and the inclined guide platform 122, together with the soft pad 123, reduces the impact of downward sliding and ensures the stability of transmission. Furthermore, the adjusting component 4 includes a first connecting frame 46 disposed at the top of the support frame 22, a connecting plate 461 rotatably disposed in the first connecting frame 46, a mounting plate 462 disposed on the connecting plate 461, the top end of the connecting plate 461 being fixedly connected to the bottom end of the movable plate 463, and the bottom of the movable plate 463 being fixedly attached; the mounting plate 462 is located in the length direction of the connecting plate 461 and in the lower half of the connecting plate 461; when the connecting plate 461 swings, the movable plate 463 reciprocates in the mounting plate 232; the first connecting frame 46 supports the swing of the connecting plate 461, and the mounting plate 462 being located in the lower half achieves a lever-saving effect, driving the movable plate 463 to reciprocate stably; Furthermore, the adjustment component 4 includes a fixed plate 41 mounted on the support frame 22, a mounting rod 42 rotatably mounted in the fixed plate 41, and a cam plate 45 fixed at one end of the mounting rod 42; after the cam plate 45 rotates, it abuts against the mounting plate 462; the fixed plate 41 fixes the mounting rod 42, and the cam plate 45 rotates to abut against the mounting plate 462 to realize power transmission and ensure transmission reliability; Furthermore, the adjustment component 4 includes a first fixing frame 481 disposed outside the second connecting frame 47, a second fixing frame 482 disposed at the bottom end of the mounting plate 232, and a connecting spring 49 disposed between the first fixing frame 481 and the second fixing frame 482; when the cam plate 45 is in contact with the mounting plate 462, the connecting spring 49 is in a stretched state; when the cam plate 45 loses contact with the mounting plate 462, the connecting spring 49 is in a contracted state; the first fixing frame 481 and the second fixing frame 482 fix the connecting spring 49, and the switching between the stretched and contracted states realizes the return reset of the movable plate 463, avoiding pushing jams; Furthermore, a servo motor 31 is installed on the base plate 1. First pulleys 32 are installed on the output shaft of the servo motor 31 and the drive shaft of the conveyor belt 12. A first belt 33 is connected to the two first pulleys 32. Second pulleys 43 are installed on the drive shaft of the conveyor belt 12 and the exterior of the mounting rod 42. A second belt 44 is connected to the two second pulleys 43. When the servo motor 31 is in driving mode, the first pulleys 32 rotate. Under the transmission of the first belt 33, the drive shaft of the conveyor belt 12 rotates, and the mounting rod 42 rotates under the transmission of the second pulleys 43 and the second belt 44. This achieves synchronous driving of the conveyor belt 12 and the mounting rod 42, ensuring coordinated feeding and conveying actions.

[0013] The working principle of this utility model is as follows: The conveyor belt 12 of the first mounting frame 11 on the base plate 1 and the storage frame 23 of the support frame 22 of the second mounting frame 21 work together. After the servo motor 31 is started, the output shaft drives the transmission shaft of the conveyor belt 12 to rotate through the first pulley 32 and the first belt 33. At the same time, the second pulley 43 and the second belt 44 drive the mounting rod 42 to rotate. The cam plate 45 at the end of the mounting rod 42 abuts against the mounting plate 462 as it rotates, pushing the connecting plate 461 to swing on the first connecting frame 46, thereby driving the movable plate 463 to slide back and forth in the mounting plate 232. At this time, the actuating block 464 is designed in a fan shape. When sliding, it pushes the plastic gear shaft in the storage frame 23 along the arc plate 231 and guides the flow through the outlet 23. After exiting from the 3rd stage, the material slides obliquely down the guide platform 122 to the conveyor belt 12. The oblique baffles 121 are symmetrically arranged to prevent material deviation, and the soft pads 123 on the inner wall of the guide platform 122 reduce impact. When the cam plate 45 disengages from the mounting plate 462, the connecting spring 49 between the first fixed frame 481 and the second fixed frame 482 retracts and resets, pulling the movable plate 463 back. The sliding block 464 slides and makes non-pushing contact with the material in the storage box 23 to avoid jamming. The entire process is achieved through the synchronous drive of the servo motor 31, the abutment transmission between the cam plate 45 and the connecting plate 461, and the elastic reset of the connecting spring 49, so as to realize the continuous and stable feeding of the plastic gear shaft from the storage box 23 to the conveyor belt 12, ensuring production efficiency and equipment reliability.
