Description

Technical Field

[0001] The invention relates to the technical field of grinding, and in particular to a grinding device for processing bottle caps. Background Art

[0002] During the production process of the bottle cap, both the inner and outer circumferential surfaces thereof need to be polished by a polishing device to make the surface smooth. There are many devices for polishing the inner and outer circumferential surfaces of the bottle cap in the prior art.

[0003] For example, the invention patent with application number CN202110617155.X, publication (announcement) number CN113211206B, and name “A grinding device for bottle cap production” discloses “a grinding component, a clamping component, a bottle cap turntable and a turntable linkage component. The grinding component is used to grind the inner wall of the cavity at the top of the bottle cap. The clamping component is used to clamp and fix the bottle cap to be polished. The bottle cap turntable can carry multiple bottle caps for rotation at the same time to send the bottle caps to be polished to the polishing station and send the polished bottle caps away from the polishing station at the same time. The turntable linkage component can drive the bottle cap turntable to rotate when the clamping component loosens the bottle cap, and the turntable linkage component can drive the bottle cap turntable to rotate each time to send the next bottle cap to be polished to the polisher”, which can improve the grinding efficiency to a certain extent.

[0004] Among them, in the above patent, in order to improve efficiency, when fixing the bottle cap, the bottle cap is automatically fixed with the help of the power of the cylinder in the process of the cylinder driving the grinding wheel to move downward. This is also a good improvement on the prior art. However, in the process of grinding the inner wall of the bottle cap, a large amount of debris will be generated and part of it will fall on the top of the bottle cap and the inner cavity of the bottle cap. If you want to clean the debris that has fallen on the top of the bottle cap and the inner cavity of the bottle cap, the operator can only carefully remove the bottle cap from the grinding station and transfer it and then perform the cleaning operation separately. This will not only cause the debris that has fallen on the bottle cap to be easily spilled during the process of removing and transferring the bottle cap, but also increase the energy consumption of the operator when carefully removing and transferring the bottle cap. It can be seen from this that how to maintain the existing technology of using the cylinder to drive the grinding wheel to move downward to achieve automatic fixation of the bottle cap with the help of the power of the cylinder, while also being able to automatically clean the debris that falls on the top of the bottle cap and the inner cavity before the bottle cap is removed from the grinding station to avoid the operator carefully removing the bottle cap from the grinding station and transferring it and then performing a separate cleaning operation is a technical problem that needs to be solved urgently. Summary of the invention

[0008] In the process of driving the grinding wheel to move downward to grind the bottle cap, the cylinder drives the second connecting member to drive the material receiving mechanism to slide into the fixing box to the limit position so that the bottle cap is rotated to a vertical state with the opening facing upward, and at the same time drives the first connecting member to drive the swing member to squeeze the bottle cap so that the bottle cap is fixed in the vertical state;

[0009] After grinding is completed, the cylinder drives the grinding wheel to move upward and reset, and resets the swinging member through the first connecting member. At the same time, the material receiving mechanism is elastically slid out of the fixed box through the second connecting member to push the bottle cap to rotate and tilt, and then pour the debris falling on the bottle cap into the material receiving mechanism.

[0019] Beneficial effects:

[0020] 1. In the above technical scheme, the present invention provides a grinding device for bottle cap processing. By setting the bottle cap in a rotating form, the cooperation between the swinging member and the material receiving mechanism is cleverly utilized, so that in the process of the cylinder driving the grinding wheel to move downward to grind the inner circumferential surface of the bottle cap, not only can the second connecting member be driven to pull the material receiving mechanism to slide toward the inner side of the fixing box to realize the vertical alignment of the bottle cap, so that the grinding wheel can be accurately inserted into the bottle cap, but also the first connecting member can be driven to make the swinging member squeeze the fixed bottle cap so that the bottle cap can be stably polished. More importantly, in the process of the grinding wheel resetting upward, the swinging member can be separated from the bottle cap first, so as to release the fixation of the bottle cap, and then the material receiving mechanism can be elastically slid out of the fixing box to push the bottle cap to rotate tiltably, so as to pour the debris falling on the bottle cap into the material receiving mechanism for collection, and finally the bottle cap can be removed from the elastic clamping ring, and the operator does not need to carefully remove the bottle cap and transfer it and then perform the cleaning operation separately. It can be seen that the prior art can maintain the automatic fixation of the bottle cap by the power of the cylinder in the process of driving the grinding wheel downward by the cylinder, and can also automatically clean the debris on the top of the bottle cap and in the inner cavity before the bottle cap is removed from the grinding station to avoid the operator carefully removing the bottle cap from the grinding station and transferring it and then performing the cleaning operation separately, which can effectively solve the shortcomings of the prior art;

[0021] 2. Furthermore, the cooperation between the swing member and the material receiving mechanism in the present invention not only realizes the correction of the position of the bottle cap so that the grinding wheel can be accurately inserted into the bottle cap, but also realizes the fixation of the bottle cap after the correction so that the inner circumference of the bottle cap can be stably polished, and at the same time realizes the pouring of the debris on the bottle cap after the polishing into a specific position, so that the debris falling on the top of the bottle cap and the inner cavity can be automatically cleaned before the bottle cap is removed from the polishing station, so as to avoid the operator carefully removing the bottle cap from the polishing station and transferring it and then performing the cleaning operation separately. It can be seen that the present invention realizes multiple different functions through the ingenious cooperation between the swing member and the material receiving mechanism, so that it has unexpected technical effects;

[0022] 3. In the process of the receiving mechanism sliding toward the outside of the fixed box to push the bottle cap to rotate and tilt, the receiving plate is unexpectedly driven to rotate and tilt so that the debris falling on the receiving plate slides into the groove and is collected, which produces the technical effect of preventing the debris from continuously accumulating on the receiving plate so that the receiving plate can maintain sufficient accommodating space when receiving the debris next time;

[0023] 4. Furthermore, in the present invention, when the bottle cap is inserted into the elastic clamping ring, the elastic clamping ring is first rotated to a horizontal state, and the insertion is stopped when the end face of the bottle cap reaches the left protrusion so that the elastic clamping ring can be clamped at a specific position of the bottle cap each time. It can be seen that the setting of the push block also plays a role in enabling the bottle cap to be inserted into the elastic clamping ring each time, thereby achieving that each time the bottle cap is pushed and rotated, the left protrusion can slide to a specific position of the bottle cap and the right protrusion can abut against the end face of the bottle cap each time to push the bottle cap to rotate at an angle greater than 90°.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] like Figure 1-16 As shown, a grinding device for bottle cap processing provided by an embodiment of the present invention comprises a grinding wheel 19 for grinding the bottle cap 11 and a cylinder 16 for driving the grinding wheel 19 to move up and down, the cylinder 16 is fixedly mounted on a frame, an elastic clamping ring 12 for clamping the bottle cap 11 is rotatably arranged on the frame through a shaft 13, a fixing box 1 is fixedly mounted on the frame, a material receiving mechanism is elastically and slidably inserted in the fixing box 1, one end of the material receiving mechanism is located outside the fixing box 1 and abuts against the bottle cap 11;

[0045] A swinging piece is elastically rotatably provided on the fixed box 1, the shaft 13 is located between the swinging piece and the material receiving mechanism, and the power output end of the cylinder 16 is connected to the swinging piece through a first connecting piece and connected to the material receiving mechanism through a second connecting piece;

[0046] In the process of driving the grinding wheel 19 to move downward to grind the bottle cap 11, the cylinder 16 drives the second connecting member to drive the material receiving mechanism to slide into the fixing box 1 to the limit position so that the bottle cap 11 rotates to a vertical state with the opening facing upward, and at the same time drives the first connecting member to drive the swing member to squeeze the bottle cap 11 so that the bottle cap 11 is fixed in the vertical state;

[0047] After grinding is completed, the cylinder 16 drives the grinding wheel 19 to move up and reset, and resets the swing member through the first connecting member. At the same time, the material receiving mechanism is elastically slid out of the fixed box 1 through the second connecting member to push the bottle cap 11 to rotate and tilt, and then the debris falling on the bottle cap 11 is poured into the material receiving mechanism.

[0048] The bottle cap processing grinding device provided in this embodiment is used to grind the inner circumference of the bottle cap, and the words related to direction and position involved in this embodiment are relative to the accompanying drawings. Specifically, the cylinder 16 is preferably a servo cylinder, and the power output end of the cylinder 16 is fixedly installed with a motor 18, and the grinding wheel 19 is fixedly installed on the output shaft of the motor 18. The motor 18 drives the grinding wheel 19 to rotate, and the cylinder 16 drives the grinding wheel 19 to move up and down to achieve the grinding of the inner circumference of the bottle cap 11. In this embodiment, the elastic clamping ring 12 is used to clamp the bottle cap 11 so that the bottle cap 11 is relatively fixed with the elastic clamping ring 12, wherein the elastic clamping ring 12 is provided with a notch so that the elastic clamping ring 12 can use its own elasticity to undergo radial elastic deformation, and based on the radial elastic force of the elastic clamping ring 12, the bottle cap 11 is clamped, and when the bottle cap 11 is installed, the bottle cap 11 is directly inserted into the elastic clamping ring 12, which is convenient and quick. The bottom end surface of the elastic clamping ring 12 is formed with a chamfer 1201 to facilitate the insertion of the bottle cap 11 into the elastic clamping ring 12 from the bottom of the elastic clamping ring 12. Two coaxial shafts 13 are fixedly mounted on the elastic clamping ring 12, and the elastic clamping ring 12 is located between the two shafts 13. Two support plates 14 that are rotatably connected to the two shafts 13 are fixedly mounted on the frame. When the bottle cap 11 is inserted into the elastic clamping ring 12, the bottle cap 11 and the elastic clamping ring 12 can rotate synchronously around the axis of the shaft 13.

[0049] Since debris will fall onto the bottle cap 11 after polishing, such as the inner cavity of the bottle cap 11 and the top of the bottle cap 11, in this embodiment, the material receiving mechanism is used to receive the debris falling on the bottle cap 11, and can collect the debris falling on the bottle cap 11 before the bottle cap 11 is removed from the processing station. At the same time, one end of the material receiving mechanism is located outside the fixing box 1 and abuts against the bottle cap 11 inserted in the elastic clamping ring 12. In addition to collecting the debris, the material receiving mechanism is also used to limit the bottle cap 11 so that the bottle cap 11 maintains a vertical state with the opening upward, and is also used to cooperate with the swinging member to fix the bottle cap 11.

[0050] The swing member is elastically rotatably arranged on the fixed box 1, and the shaft 13 is located between the swing member and the material receiving mechanism, so that when the material receiving mechanism remains fixed and abuts against the bottle cap 11, the swing member can fix the bottle cap 11 after squeezing the bottle cap 11.

[0051] More specifically, the power output end of the cylinder 16 is connected to the swing member through the first connecting member and is connected to the material receiving mechanism through the second connecting member. In the process of the cylinder 16 driving the grinding wheel 19 to move down to grind the bottle cap 11, the cylinder 16 drives the second connecting member to drive the material receiving mechanism to slide to the limit position in the fixed box 1. During this process, the bottle cap 11 inserted into the elastic clamping ring 12 rotates around the shaft 13 under the action of gravity. When the material receiving mechanism slides to the limit position in the fixed box 1, the bottle cap 11 rotates to a vertical state with the opening facing upward. At the same time, the cylinder 16 drives the first connecting member to drive the swing member to squeeze the bottle cap 11 so that the bottle cap 11 is fixed in a vertical state. Thereafter, the grinding wheel 19 moves down to the inner cavity of the bottle cap 11 and drives the grinding wheel 19 to rotate through the motor 18 to grind the inner circumferential surface of the fixed box 1. During the entire grinding process, the bottle cap 11 is always in a vertical state with the opening facing upward.

[0052] After grinding is completed, the cylinder 16 drives the grinding wheel 19 to move up and reset, and then resets the swinging member through the first connecting member to release the bottle cap 11. At the same time, the material receiving mechanism is elastically slid out of the fixing box 1 through the second connecting member. During the sliding out process of the material receiving mechanism, the bottle cap 11 is pushed to rotate and tilt, and then the debris falling on the bottle cap 11 is poured into the material receiving mechanism, and then the bottle cap 11 can be taken out from the elastic clamping ring 12.

[0053] Its working principle is as follows: first, the elastic clamping ring 12 is rotated to an inclined state to leave space for the insertion of the bottle cap 11, then the bottle cap 11 is inserted into the elastic clamping ring 12 from the bottom of the elastic clamping ring 12 and clamped by the elastic clamping ring 12, the bottle cap 11 is stopped and released after being inserted to a specific length, the bottle cap 11 rotates around the shaft 13 under the action of gravity until it abuts against the material receiving mechanism, then the cylinder 16 is started, the power output end of the cylinder 16 drives the grinding wheel 19 to move down close to the bottle cap 11, and drives the second connecting member to drive the material receiving mechanism to slide elastically toward the inside of the fixed box 1, and the bottle cap 11 will continue to rotate under the action of gravity as the material receiving mechanism slides, and when the material receiving mechanism slides to the limit position, the bottle cap 11 rotates to a vertical state with the opening facing upward. Then the power output end of the cylinder 16 drives the first connecting member to drive the swinging member to rotate toward the bottle cap 11 so that the swinging member squeezes the bottle cap 11, so that the bottle cap 11 is fixed in a vertical state. Then the grinding wheel 19 moves down to the inner cavity of the bottle cap 11 , and the motor 18 is started to drive the grinding wheel 19 to rotate to grind the inner wall of the bottle cap 11 , and the debris generated during grinding falls into the inner cavity of the bottle cap 11 and the top surface of the bottle cap 11 . After the grinding is completed, the motor 18 stops running, and then the cylinder 16 is started to drive the grinding wheel 19 to move upward. When the grinding wheel 19 is moved out of the inner cavity of the bottle cap 11, the swinging member is elastically rotated and reset through the first connecting member to release the fixation of the bottle cap 11. Then, the material receiving mechanism is slid toward the outside of the bottle cap 11 through the second connecting member so that the material receiving mechanism pushes the bottle cap 11 to rotate around the shaft 13, wherein the material receiving mechanism is staggered with the notch on the elastic clamping ring 12 so that the material receiving mechanism does not contact the elastic clamping ring 12 during the process of pushing the bottle cap 11. The rotation direction of the bottle cap 11 is that its top rotates toward the material receiving mechanism. As the bottle cap 11 continues to rotate, the debris falling on the top of the bottle cap 11 and the inner cavity gradually falls into the material receiving mechanism and is collected. Finally, the bottle cap 11 is pulled out of the elastic clamping ring 12 to achieve unloading.

[0054] Thus, the present invention, by setting the bottle cap 11 in a rotating form, cleverly utilizes the cooperation between the swinging member and the material receiving mechanism, so that in the process of the cylinder 16 driving the grinding wheel 19 to move downward to grind the inner circumferential surface of the bottle cap 11, it can not only first drive the second connecting member to pull the material receiving mechanism to slide toward the inner side of the fixed box 1 to realize the vertical alignment of the bottle cap 11, so that the grinding wheel 19 can be accurately inserted into the bottle cap 11, but also drive the first connecting member to make the swinging member squeeze and fix the bottle cap 11 so that the bottle cap 11 is stably grinded, and more importantly, in the process of the grinding wheel 19 resetting upward, the swinging member can be separated from the bottle cap 11 first, so as to release the fixation of the bottle cap 11, and then the material receiving mechanism can be elastically slid out of the fixed box 1 to push the bottle cap 11 to rotate tiltedly, so as to pour the debris falling on the bottle cap 11 into the material receiving mechanism for collection, and finally the bottle cap 11 can be removed from the elastic clamping ring 12, and the operator does not need to carefully remove the bottle cap and transfer it and then perform the cleaning operation separately. It can be seen that, while maintaining the prior art of using the cylinder to drive the grinding wheel downward to achieve automatic fixation of the bottle cap with the help of the power of the cylinder, the debris that falls on the top of the bottle cap and the inner cavity can be automatically cleaned before the bottle cap is removed from the grinding station to avoid the operator carefully removing the bottle cap from the grinding station and transferring it and then performing a cleaning operation separately.

[0055] Furthermore, the cooperation between the swinging member and the material receiving mechanism in the present invention not only realizes the adjustment of the position of the bottle cap 11 so that the grinding wheel 19 can be accurately inserted into the bottle cap 11, but also realizes the fixation of the bottle cap 11 after the adjustment so that the inner circumference of the bottle cap 11 can be stably polished, and at the same time realizes the pouring of the debris on the bottle cap 11 after the polishing into a specific position, so that the debris fallen on the top of the bottle cap and the inner cavity can be automatically cleaned before the bottle cap 11 is removed from the polishing station, so as to avoid the operator carefully removing the bottle cap from the polishing station and transferring it and then performing the cleaning operation separately. It can be seen that the present invention realizes multiple different functions through the ingenious cooperation between the swinging member and the material receiving mechanism, which makes it have unexpected technical effects.

[0056] In this embodiment, the first connecting member includes a second elastic rope 23, a first directional wheel 20 and a second directional wheel 21 are rotatably arranged on the frame, the second elastic rope 23 passes around the first directional wheel 20 and the second directional wheel 21 in sequence, a connecting plate 17 is fixedly installed at the power output end of the cylinder 16, one end of the second elastic rope 23 is fixedly connected to the connecting plate 17, and the other end is fixedly connected to the swing member. The connection point between the second elastic rope 23 and the swing member is located below the rotation center of the swing member, and the second elastic rope 23 is in a relaxed state in the initial state. When the cylinder 16 drives the connecting plate 17 to move downward, the second elastic rope 23 is continuously pulled to tighten the second elastic rope 23, and then the second elastic rope 23 pulls the swing member to rotate so that the top of the swing member rotates toward the bottle cap 11, thereby squeezing the bottle cap 11. The first directional wheel 20 and the second directional wheel 21 are both used to change the direction of the second elastic rope 23. The part of the second elastic rope 23 between the first directional wheel 20 and the connecting plate 17 is in a vertical state. The second directional wheel 21 and the connecting plate 17 are staggered in the left and right directions so that the second directional wheel 21 and the second elastic rope 23 will not contact the connecting plate 17. Since the second elastic rope 23 is elastic, after the swinging member squeezes the bottle cap 11, the power output end of the cylinder 16 can continue to move downward. At this time, the swinging member keeps squeezing the bottle cap 11, and as the power output end of the cylinder 16 moves downward continuously, the swinging member squeezes and fixes the bottle cap 11 more firmly.

[0057] In this embodiment, the second connecting member includes a first elastic rope 22, a pull rope 24, and a limiting bead 27. The pull rope 24 is preferably made of an inelastic material. A third directional wheel 28 and an upper rotating wheel 25 and a lower rotating wheel 26 are rotatably arranged on the frame. One end of the first elastic rope 22 passes around the first directional wheel 20 and is fixedly connected to the connecting plate 17, and the other end is pressed and passed between the upper rotating wheel 25 and the lower rotating wheel 26 and is fixedly connected to the limiting bead 27. One end of the pull rope 24 is fixedly connected to the limiting bead 27, and the other end passes around the third directional wheel 28 and passes through the fixed box 1 and is fixedly connected to the material receiving mechanism. Specifically, a through hole 102 is provided on the fixing box 1, and the pull rope 24 is fixedly connected to the center of the material receiving mechanism after passing through the through hole 102. When the power output end of the cylinder 16 drives the connecting plate 17 to move downward, the first elastic rope 22 and the pull rope 24 are tightened and the material receiving mechanism is pulled to slide elastically toward the inside of the fixing box 1. When the material receiving mechanism slides to a specific position, the bottle cap 11 is in a vertical state with its opening facing upward. At this time, the limiting bead 27 abuts against the upper rotating wheel 25 and the lower rotating wheel 26 at the same time, so that the limiting bead 27 will not continue to be pulled upward, thereby realizing the limiting of the material receiving mechanism. Thereafter, as the connecting plate 17 continues to move downward, the material receiving mechanism no longer slides to keep the bottle cap 11 in a vertical state with its opening facing upward. At the same time, since the first elastic rope 22 is elastic, the connecting plate 17 can continue to move downward to allow the grinding wheel 19 to grind the inner circumferential surface of the bottle cap 11.

[0058] In this embodiment, the swinging member is rotatably connected to the fixed box 1 through the shaft 701, and an arc rod 9 coaxial with the shaft 701 is fixedly installed on the fixed box 1. An arc compression spring 10 is sleeved on the arc rod 9, one end of which abuts against the fixed box 1 and the other end abuts against the swing plate 7. A limiting cap 901 is installed on the free end of the arc rod 9. The elastic rotation of the swinging member is realized under the elastic force of the arc compression spring 10, and the limiting cap 901 is used to limit the swinging member.

[0059] The swinging member includes a swing plate 7, on which an extension plate 702 is integrally provided for sliding and plugging with the arc rod 9, one end of the swing plate 7 is located outside the fixing box 1 and is rotatably provided with a double wheel 8 abutting against the outer side of the bottle cap 11, and the double wheel 8 is located above the shaft rod 13. The second elastic rope 23 is fixedly connected to the bottom of the swing plate 7, and the shaft body 701 is rotatably connected to the swing plate 7. Under the elastic force of the arc compression spring 10, the swing plate 7 abuts against the limiting cap 901, and the double wheel 8 is separated from the bottle cap 11. When the power output end of the cylinder 16 drives the connecting plate 17 to move downward and pull the second elastic rope 23, the second elastic rope 23 pulls the swing plate 7 to rotate around the shaft body 701 to squeeze the arc compression spring 10 to produce elastic deformation, thereby driving the double wheel 8 to rotate toward the bottle cap 11 until the bottle cap 11 is squeezed and fixed. It should be noted that, in this embodiment, during the downward movement of the power output end of the cylinder 16, the first connecting member pulls the material receiving mechanism to slide first, and the second connecting member pulls the swing member to rotate later. Conversely, during the upward movement of the power output end of the cylinder 16, the swing member rotates first, and the material receiving mechanism slides later.

[0060] In this embodiment, the material receiving mechanism includes a push block 5 and a draw box 2 that are fixedly connected. The draw box 2 is elastically slidably plugged with the fixed box 1 through a straight compression spring 4. A guard plate 504 is integrally provided on the side of the push block 5 away from the draw box 2. The arc surface 5041 on the guard plate 504 fits the outer peripheral surface of the bottle cap 11 in a vertical state. At this time, the draw box 2 is located at the extreme position inside the fixed box 1, and the push block 5 is located below the shaft 13. Specifically, the straight compression spring 4 is located in the inner cavity of the fixed box 1, one end of the straight compression spring 4 is fixedly connected to the draw box 2, and the other end is fixedly connected to the inner wall of the fixed box 1, and the arc surface of the arc surface 5041 fits the outer peripheral surface of the bottle cap 11 in a vertical state.

[0061] Among them, a recessed groove 501 is opened on the top of the pushing block 5 to form a left protrusion 502 and a right protrusion 503 on the top of the pushing block 5. The height of the right protrusion 503 is higher than the left protrusion 502 so that when the left protrusion 502 pushes the bottle cap 11 to rotate, the right protrusion 503 abuts against the end surface of the bottle cap 11. The right protrusion 503 pushes the end surface of the bottle cap 11 so that the rotation angle of the bottle cap 11 is greater than 90°, thereby pouring out the debris in the inner cavity of the bottle cap 11.

[0062] Combined with the above disclosed structure, its working principle is as follows: when the cylinder 16 drives the grinding wheel 19 to move downward, the connecting plate 17 first pulls the first elastic rope 22 to move, the first elastic rope 22 pulls the limit bead 27 and the pull rope 24 to move upward, and the pull rope 24 then pulls the drawer box 2 to slide inside the fixed box 1 so that the straight compression spring 4 is compressed, and at the same time the drawer box 2 drives the push block 5 to move synchronously. In this process, the loose second elastic rope 23 is gradually tightened. When the limit bead 27 is simultaneously with the upper rotating wheel 25 and the lower rotating wheel 26, the drawer box 2 drives the push block 5 to move synchronously. When abutting, as the connecting plate 17 continues to move downward, the first elastic rope 22 is elastically stretched, and at the same time, the second elastic rope 23 pulls the swing plate 7 to rotate so that the double wheels 8 abut against the bottle cap 11 in a vertical state and squeeze the bottle cap 11 to fix the bottle cap 11. After that, the second elastic rope 23 is elastically stretched to keep the bottle cap 11 in a vertical state and fixed. Then the grinding wheel 19 enters the bottle cap 11 and is driven by the motor 18 to rotate to grind the inner circumference of the bottle cap 11. After the polishing is completed, as the power output end of the cylinder 16 moves upward, the second elastic rope 23 and the first elastic rope 22 gradually shrink, and the swing plate 7 rotates in the opposite direction and resets under the elastic force of the arc compression spring 10. Under the elastic force of the straight compression spring 4, the drawer box 2 and the push block 5 slide toward the outside of the fixed box 1, so that the push block 5 continuously pushes the polished bottle cap 11 to rotate. In this process, the left protrusion 502 first pushes the bottle cap 11 to rotate, and at the same time, the left protrusion 502 and the bottle cap 11 generate relative movement, so that the left protrusion 502 gradually moves toward the top direction of the bottle cap 11 (such as Fig.12 , 13 As shown in FIG. 1 , when the outer surface of the bottle cap 11 is completely in contact with the top surface of the left protrusion 502, the bottle cap 11 is in a horizontal state or nearly in a horizontal state. Since the height of the right protrusion 503 is higher than that of the left protrusion 502, the right protrusion 503 is in contact with the top surface of the bottle cap 11 (as shown in FIG. 1 ). Fig.14 As shown in the figure, the bottle cap 11 is pushed to continue to rotate under the action of the right protrusion 503 so that the debris on the top surface of the bottle cap 11 and in its inner cavity can be poured out more completely. In the process of the right protrusion 503 pushing the bottle cap 11 to rotate, the recessed groove 501 can play the role of avoiding the bottle cap 11 and accommodating part of the debris. Part of the debris poured out from the bottle cap 11 falls into the drawer box 2 and part falls into the recessed groove 501. Then the cylinder 16 stops running, the grinding wheel 19 is reset, and finally the bottle cap 11 is removed from the elastic clamping ring 12.

[0063] Further, the material receiving mechanism also includes a collection box 3 that is slidably plugged with the drawer box 2 and a receiving plate 6 that is rotatably arranged in the drawer box 2 through a rotating shaft 602. A seesaw 601 is integrally arranged on the receiving plate 6. In the initial state, the receiving plate 6 is in a horizontal state. During the process that the material receiving mechanism slides toward the outside of the fixed box 1 to push the bottle cap 11 to rotate, the seesaw 601 abuts against the swing plate 7 to make the receiving plate 6 rotate and tilt up, thereby sliding the debris that falls on the receiving plate 6 into the groove 301 on the collection box 3 for storage. Specifically, two symmetrically arranged rotating holes 202 are provided on the drawer box 2, and a rotating shaft 602 is plugged on the receiving plate 6. The two ends of the rotating shaft 602 are rotatably plugged in the two rotating holes 202 in a one-to-one manner. A plurality of pads 201 are fixedly arranged on the bottom surface of the inner cavity of the drawer box 2 to support the receiving plate 6, so that the receiving plate 6 is in a horizontal state in the initial state, thereby making the drawer box 2 have a larger inner cavity space. When the material receiving mechanism slides outward from the fixed box 1, the drawer box 2 begins to slide out of the fixed box 1, so that when the material receiving mechanism pushes the bottle cap 11 to rotate and tilt, the debris falling on the top of the bottle cap 11 first falls on the receiving plate 6 in the drawer box 2 and is collected. When the material receiving mechanism slides back to the inside of the fixed box 1, the drawer box 2 completely enters the fixed box 1, thereby preventing the collected debris from being thrown out. More importantly, during the sliding process of the material receiving mechanism toward the outside of the fixed box 1, the seesaw 601 gradually abuts against the swing plate 7. Since the swing plate 7 is limited by the limiting cap 901 and cannot rotate, the seesaw 601 drives the receiving plate 6 to rotate around the rotating shaft 602 under the blocking effect of the swing plate 7. After the receiving plate 6 rotates and tilts, the debris falling on the receiving plate 6 slides into the groove 301 and is collected, so that the receiving plate 6 can maintain sufficient accommodation space when receiving the debris next time.

[0064] It can be seen that in the present invention, when the material receiving mechanism slides toward the outside of the fixed box 1 to push the bottle cap 11 to rotate and tilt, it unexpectedly achieves the effect of driving the receiving plate 6 to rotate and tilt so that the debris falling on the receiving plate 6 slides into the groove 301 and is collected, thereby preventing the debris from continuously accumulating on the receiving plate 6 so that the receiving plate 6 can maintain sufficient accommodating space when receiving the debris next time.

[0065] The fixed box 1 is provided with an insertion port for inserting the collection box 3, and a door panel 15 is slidably inserted at the insertion port. The collection box 3 is provided with an avoidance hole 302 corresponding to the rocker 601. The collection box 3 is taken out from the fixed box 1 by pulling up the sliding door panel 15 to open the insertion port. Specifically, the insertion port is provided on the front side of the fixed box 1. When there are many debris stored in the groove 301, the insertion port on the fixed box 1 is opened by pulling up the door panel 15, and the collection box 3 can be taken out from the fixed box 1, so as to facilitate the cleaning of the collected debris.

[0066] In this embodiment, a guide plate 303 is fixedly installed on the side of the collection box 3, and a slide groove 203 for sliding insertion of the guide plate 303 is opened on the inner wall of the drawer box 2. The sliding connection between the guide plate 303 and the slide groove 203 is realized by sliding connection between the collection box 3 and the drawer box 2.

[0067] In this embodiment, Fig.10 and 11 As shown, when the bottle cap 11 is inserted into the elastic clamping ring 12, the elastic clamping ring 12 is first rotated to a state where the axis is horizontal, and the insertion is stopped when the end face of the bottle cap 11 reaches the left protrusion 502 so that the elastic clamping ring 12 can be clamped at a specific position of the bottle cap 11 each time. It can be seen that the setting of the push block 5 also plays a role in enabling the bottle cap 11 to be inserted into the elastic clamping ring 12 each time, so that each time the bottle cap 11 is pushed and rotated, the left protrusion 502 can slide to a specific position of the bottle cap 11 and the right protrusion 503 can abut against the end face of the bottle cap 11 each time to push the bottle cap 11 to rotate at an angle greater than 90°.

[0068] Among them, a baffle 101 is fixedly installed in the inner cavity of the fixed box 1 and abuts against the side of the drawer box 2. When the drawer box 2 slides toward the inside of the fixed box 1 and abuts against the baffle 101, the material receiving mechanism is located at the extreme position. By setting the baffle 101, the function of the limiting bead 27 can be replaced. This is another way to make the material receiving mechanism slide to the extreme position inside the fixed box 1.

[0069] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
