Description

Technical Field

[0001] This utility model relates to the field of spring grinding machine feeding technology, and in particular to a spring grinding machine feeding vibrating screen device. Background Technology

[0002] Springs, as important mechanical parts, are widely used in many fields such as automobiles, machinery manufacturing, electronic equipment, and aerospace. In these applications, there are many situations where the precision, surface quality, and performance of springs are strictly required. In the spring production process, after the spring is wound and formed, in order to ensure its perpendicularity, ensure good contact between the end face of the support coil and other parts, and reduce deflection characteristics, both end faces of the spring need to be ground. In the early days, the grinding of spring end faces was mostly done manually and with simple mechanical devices. Manual operation was not only slow, but also difficult to ensure the consistency of processing accuracy. At the same time, it was labor-intensive and had low production efficiency. With the expansion of spring production scale and the improvement of quality requirements, automatic spring grinding machines began to appear. Along with the use of automatic spring grinding machines, the feeding devices for spring grinding machines were also put into use.

[0003] Traditional spring grinding machine feeding mainly relies on manual operation, which is labor-intensive, inefficient, and prone to affecting product quality due to operational errors. With the development of the times and technology, automatic spring grinding machine feeding devices have begun to be used. These include hopper-type feeding devices that place springs in a hopper and transport them one by one to the feeding position of the spring grinding machine through the discharge port at the bottom of the hopper and the feeding mechanism, and belt-type feeding devices that transport springs from the storage area to the feeding position of the spring grinding machine via belt drive. However, both of these devices cannot effectively disperse springs that are piled up and partially tangled together, requiring manual separation, which leads to reduced production efficiency and increased labor costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vibrating screen device for feeding spring grinding machines, which aims to improve the problem that traditional feeding devices for spring grinding machines in the prior art cannot effectively disperse piled-up and partially tangled springs, requiring manual separation, resulting in reduced production efficiency and increased labor costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding vibrating screen device for a grinding spring machine, comprising a feeding funnel, a hollow cylinder fixedly connected to the bottom of the feeding funnel, an asynchronous motor fixedly connected to the inner wall of the hollow cylinder, an eccentric wheel fixedly connected to the output end of the asynchronous motor, a first rotating rod rotatably connected to the outer wall of the eccentric wheel, a positioning shaft rotatably connected to the middle of the outer wall of the eccentric wheel, a moving column rotatably connected to the top of the first rotating rod, a limit plate fixedly connected to the top of the moving column, a filter plate slidably connected to the inner wall of the feeding funnel, multiple sliding columns fixedly connected to the bottom of the filter plate, a return spring fixedly connected to the bottom end of the sliding column, multiple hollow tubes fixedly connected to the top of the hollow cylinder, and multiple unloading mechanisms rotatably connected to the front side of the outer wall of the feeding funnel, the unloading mechanisms being used to quickly discharge the dispersed material.

[0006] Through the above technical solution: when the spring causes the moving column to move up and down, it will cooperate with the filter plate to make the filter plate vibrate. The spring provides elastic buffer for the vibration of the filter plate, so that the material jumps continuously on the filter plate, thereby achieving full screening and dispersion. As the eccentric wheel rotates, the first rotating rod can also swing regularly, thereby driving the moving column to reciprocate in the vertical direction. The unloading mechanism can quickly send the screened material out of the feed hopper and transport it to the feed port of the grinding spring machine.

[0007] As a further description of the above technical solution:

[0008] The unloading mechanism includes a rotating plate, the outer wall of which is rotatably connected to the outer wall of the feeding hopper. A positioning block is fixedly connected to the outer wall of the rotating plate. Multiple locking blocks are rotatably connected to the outer wall of the feeding hopper near its edge. A limiting block is fixedly connected to the top of the hollow cylinder near its edge. A rotating column is slidably connected to the inner wall of the limiting block. A rotating shaft is rotatably connected to the inner wall of the limiting block near its edge. A rotating block is fixedly connected to the front end of the rotating shaft. A limiting groove is formed on the inner wall of the rotating column.

[0009] Through the above technical solution: the rotating column can make linear reciprocating motion along a specific trajectory under the constraint of the limiting block. The rotation of the rotating shaft can drive the rotation of the rotating block. When the rotating block rotates to the vertical state, it no longer limits the position of the limiting groove, so that the rotating column can slide within the limiting block. When the rotating block rotates to the horizontal state, it can prevent the rotating column from sliding downward.

[0010] As a further description of the above technical solution:

[0011] A rotating disk is fixedly connected to the rear end of the rotating shaft, and an anti-slip sleeve is fixedly connected to the outer wall of the rotating disk.

[0012] Through the above technical solution, the anti-slip sleeve can increase the friction of the outer wall of the rotating disk.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the hollow cylinder is rotatably connected to a second rotating rod, and the bottom of the hollow cylinder is fixedly connected to a base plate.

[0015] The above technical solution uses a base plate to support the entire device.

[0016] As a further description of the above technical solution:

[0017] Multiple hollow blocks are fixedly connected to the outer wall of the hollow cylinder near the edge, and sliding rods are slidably connected to the inner wall of the hollow blocks.

[0018] Through the above technical solution, the sliding rod can be inserted into the hollow block, thereby limiting the opening and closing of the hollow cylinder.

[0019] As a further description of the above technical solution:

[0020] The bottom of the base plate is fixedly connected to multiple mounting plates, and the inner wall of the mounting plates is threaded with screws.

[0021] The above technical solution involves screws used to install the mounting plate in the required position.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the screw is provided with a washer, and the inner wall of the washer is slidably connected to the outer wall of the screw.

[0024] Through the above technical solution, the gasket can increase the contact area between the screw and the mounting surface.

[0025] As a further description of the above technical solution:

[0026] The inner wall of the feed funnel is connected to a drain pipe, and the outer wall of the sliding column is slidably connected to the inner wall of the hollow tube.

[0027] The above technical solution involves a drain pipe used to drain water from the spring that is being cleaned simultaneously during separation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the asynchronous motor is started to drive the eccentric wheel to rotate, which in turn pulls the first rotating rod to move up and down, thereby driving the moving column to slide up and down. The limit plate pulls the filter plate to move downward. When the limit plate moves upward, the reset spring pushes the sliding column, which in turn pushes the filter plate to slide upward, thus achieving the purpose of quickly separating the stacked springs, speeding up production efficiency and reducing labor costs.

[0030] 2. In this utility model, by rotating the rotating shaft, the rotating block and the limiting groove are relatively engaged, preventing the rotating column from sliding within the limiting block. Then, the asynchronous motor is started to drive the eccentric wheel to rotate, which can pull the first rotating rod and the moving column downward, thereby pulling the filter plate downward. However, one side of the filter plate is limited by the rotating column and cannot move downward, thus tilting to one side. Then, the locking block is rotated to unlock the positioning block, thereby allowing the rotating plate to be rotated to discharge the material. This achieves the purpose of quickly transferring the separated material to the next production, speeding up production efficiency and improving practicality. Attached Figure Description

[0039] 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.

[0040] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a spring grinding machine feeding vibrating screen device, including a feeding funnel 1, which is used to place and guide springs into the device. A hollow cylinder 3 is fixedly connected to the bottom of the feeding funnel 1, and an asynchronous motor 10 is fixedly connected to the inner wall of the hollow cylinder 3 for installing and protecting part of the structure. An eccentric wheel 9 is fixedly connected to the output end of the asynchronous motor 10, and a first rotating rod 8 is rotatably connected to the outer wall of the eccentric wheel 9. The asynchronous motor 10 can provide power to the entire device. A positioning shaft 7 is rotatably connected to the middle of the outer wall of the eccentric wheel 9, and a moving column 6 is rotatably connected to the top of the first rotating rod 8. The eccentric wheel 9 can drive... The first rotating rod 8 moves up and down. The top of the moving column 6 is fixedly connected to the limiting plate 5. The inner wall of the feeding funnel 1 is slidably connected to the filter plate 4. The bottom of the filter plate 4 is fixedly connected to multiple sliding columns 11. The up and down movement of the first rotating rod 8 can drive the moving column 6 to move up and down. The bottom end of the sliding column 11 is fixedly connected to the return spring 13. The top of the hollow cylinder 3 is fixedly connected to multiple hollow tubes 12. The filter plate 4 is used to support the spring. The front side of the outer wall of the feeding funnel 1 is rotatably connected to multiple unloading mechanisms 2. The unloading mechanism 2 is used to quickly send out the dispersed material. The return spring 13 can push the sliding column 11 to slide upward and reset.

[0041] Specifically, the inverted cone shape of the feed hopper 1 not only facilitates the rapid input of materials, but also initially buffers the impact force of the materials to a certain extent, avoiding damage to subsequent components due to excessive material input. The hollow cylinder 3 provides installation space for the internal transmission components. The eccentric wheel 9 can rotate at high speed under the drive of the asynchronous motor 10, thereby generating periodic centrifugal force during rotation. The positioning shaft 7 ensures the stability and accuracy of the rotation of the eccentric wheel 9. The first rotating rod 8 reciprocates under the drive of the eccentric wheel 9 and is connected to the rotation of the moving column 6, so that the moving column 6 can move in the vertical direction while restricting its displacement in the horizontal direction. The function of the limiting plate 5 is to prevent the moving column 6 from leaving the predetermined track during movement.

[0042] Please see the appendix Figure 4 - Appendix Figure 6 The unloading mechanism 2 includes a rotating plate 201. The outer wall of the rotating plate 201 is rotatably connected to the outer wall of the feeding hopper 1. A positioning block 203 is fixedly connected to the outer wall of the rotating plate 201. A plurality of locking blocks 202 are rotatably connected to the outer wall of the feeding hopper 1 near the edge. The rotating plate 201 is used to limit the locking blocks 202. A limiting block 208 is fixedly connected to the top of the hollow cylinder 3 near the edge. A rotating column 206 is slidably connected to the inner wall of the limiting block 208. The limiting block 208 can guide the sliding of the rotating column 206. A rotating shaft 207 is rotatably connected to the inner wall of the limiting block 208 near the edge. A rotating block 205 is fixedly connected to the front end of the rotating shaft 207. A limiting groove 204 is opened on the inner wall of the rotating column 206. The rotating block 205 can engage with the limiting groove 204, thereby limiting the position of the rotating column 206.

[0043] Specifically, the positioning block 203 not only provides a reference for the rotation of the rotating plate 201, but also works with other components to control the rotation angle of the rotating plate 201, thereby controlling the amount of material discharged. When the rotating plate 201 is in the closed state, the locking block 202 can limit the position with the positioning block 203 to ensure that the rotating plate 201 closes the discharge port of the feed funnel 1 and prevents the material from falling accidentally during the screening process. When it is necessary to discharge, the positioning block 203 rotates at a certain angle, and the positioning block 203 is released so that the rotating plate 201 can rotate and open smoothly.

[0044] Please see the appendix Figure 3 - Appendix Figure 5A rotating disk 22 is fixedly connected to the rear end of the rotating shaft 207. An anti-slip sleeve 23 is fixedly connected to the outer wall of the rotating disk 22. The rotating disk 22 is used to help the user rotate the rotating shaft 207. Multiple hollow blocks 19 are fixedly connected to the outer wall of the hollow cylinder 3 near the edge. A sliding rod 20 is slidably connected to the inner wall of the hollow block 19. The hollow block 19 can be inserted and limited by the sliding rod 20. A second rotating rod 18 is rotatably connected to the outer wall of the hollow cylinder 3. A base plate 21 is fixedly connected to the bottom of the hollow cylinder 3. The base plate 21 is used to support and install the entire structure.

[0045] Specifically, the anti-slip sleeve 23 increases friction when the user holds the rotating disk 22, ensuring stable rotation even when hands are sweaty or the environment is humid, and preventing slippage that could lead to errors in unloading. The sliding rod 20 can be inserted into the inner wall of multiple hollow blocks 19 to limit the rotation of the outer wall of the hollow cylinder 3. The second rotating rod 18 is used to help the user rotate and open the hollow cylinder 3 to inspect its internal structure.

[0046] Please see the appendix Figure 2 - Appendix Figure 4 The bottom of the base plate 21 is fixedly connected to multiple mounting plates 17. The inner wall of the mounting plate 17 is threaded with screws 15. The mounting plate 17 is used to fix the base plate 21 in the required position. The inner wall of the feed funnel 1 is connected to a drain pipe 14. The outer wall of the sliding column 11 is slidably connected to the inner wall of the hollow tube 12. The drain pipe 14 can drain the water from the outer wall of the spring that is cleaned during separation. The outer wall of the screw 15 is provided with a washer 16. The inner wall of the washer 16 is slidably connected to the outer wall of the screw 15. The screw 15 can fix the mounting plate 17 in the required position.

[0047] Specifically, the gasket 16 can increase the contact area between the screw 15 and the mounting surface, disperse the pressure, and also play a certain role in preventing loosening, ensuring that the device will not shift or shake during operation. When cleaning the spring, the water flow carries impurities and dirt into the feed funnel 1 from above. Under the action of gravity, the water flow carries the cleaned impurities down the inner wall of the feed funnel 1 and finally discharges out of the device through the drain pipe 14, avoiding the accumulation of wastewater in the feed funnel 1, which would affect the screening and conveying process of the spring.

[0048] Working principle: When it is necessary to separate the springs that are wound together and twisted together, they are first placed in the feed hopper 1 so that they can be supported by the filter plate 4. Then, the asynchronous motor 10 is started to drive the eccentric wheel 9 to rotate. At the same time, the position of the eccentric wheel 9 is positioned by the positioning shaft 7, so that the first rotating rod 8 connected to the eccentric wheel 9 performs a circular motion, which in turn pushes the moving column 6 to move up and down. As the moving column 6 is pulled down by the rotation of the first rotating rod 8, it can pull the filter plate 4 to move down synchronously through the limiting plate 5, so that it squeezes the sliding column 11 and compresses the return spring 13 into the hollow tube 12. When the first rotating rod 8 is lifted up by the moving column 6, the return spring 13 will push the sliding column 11 and push the filter plate 4 to slide up, which will vibrate the spring at the top of the filter plate 4, so that it can be separated.

[0049] After separation, when the spring needs to be transported to the next device, first rotate the rotating shaft 207, which in turn drives the rotating block 205 to rotate, preventing it from sliding laterally against the inner wall of the limiting groove 204. Then, start the asynchronous motor 10 to drive the eccentric wheel 9 to rotate, which in turn pulls the first rotating rod 8 to rotate downward, thereby pulling the moving column 6 and the limiting plate 5 to move the filter plate 4 downward synchronously. The position of the rotating column 206 is limited by the position of the rotating block 205, so that when the filter plate 4 is pulled downward, one side of it cannot be moved downward, and it rotates along the top of the rotating column 206. Then, rotate the locking block 202 to release its limitation on the positioning block 203, and then rotate to open the rotating plate 201 to discharge the material.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
