[0019] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position. Example 1

[0020] A cooling earphone foam processing device, such as Figure 1-Figure 3 As shown, it includes a workbench 1 and a cutting mechanism for cutting foam boards. The cutting mechanism includes a first electric push rod 201. The first electric push rod 201 is installed in the workbench 1. The telescopic end of the first electric push rod 201 is fixedly installed with a lifting frame 202. A T-shaped rod 203 that moves in the left and right directions is elastically slidably installed in the lifting frame 202. The left end of the T-shaped rod 203 is rotatably installed with a roller. A V-shaped rod 204 that cooperates with the roller is fixedly installed on the workbench 1. When the lifting frame 202 descends, the roller moves in the V-shaped Under the action of rod 204, the T-shaped rod 203 can be driven to move to the right. The right end of the T-shaped rod 203 is fixedly installed with an inscribed ring 205. A connecting frame 206 that moves in reverse directions up and down is elastically slidably installed in the workbench 1. An outscribed ring 207 that cooperates with the T-shaped rod 203 is fixedly installed in the connecting frame 206. A feeding mechanism for moving the cut foam product 100 is provided on the connecting frame 206 and the outscribed ring 207. A separation mechanism for separating the foam product 100 from foam board waste is provided on the workbench 1.

[0021] Initially, the centers of the inner ring 205 and the outer ring 207 are misaligned. The foam board is first delivered to the workbench 1 through the feeding mechanism in the prior art, and the telescopic end of the first electric push rod 201 is controlled to extend. The telescopic end of the first electric push rod 201 drives the T-shaped rod 203 to descend through the lifting frame 202. The roller on the T-shaped rod 203 is squeezed by the outer wall of the V-shaped rod 204, driving the T-shaped rod 203 to slide to the right along the lifting frame 202. When the roller moves to the corner of the V-shaped rod 204, the centers of the inner ring 205 and the outer ring 207 are aligned. , the telescopic end of the first electric push rod 201 continues to extend, so that the lifting frame 202 continues to drive the T-shaped rod 203 to descend, and then the bottom ends of the inscribed ring 205 and the circumscribed ring 207 are aligned, and the bottom of the T-shaped rod 203 contacts the connecting frame 206, and the T-shaped rod 203 pushes the connecting frame 206 to descend downward. The connecting frame 206 is forced to drive the circumscribed ring 207 to descend. At this time, the inscribed ring 205 and the circumscribed ring 207 descend synchronously, and then the inscribed ring 205 and the circumscribed ring 207 contact the foam plate at the same time, and continue to descend to cut the foam product 100.

[0022] like Figure 3 and Figure 4 As shown, the feeding mechanism includes a sliding block 301, and the sliding block 301 that moves in the left and right directions is symmetrically and elastically installed at the bottom of the connecting frame 206. A rotating rod 302 that cooperates with the sliding block 301 is symmetrically and elastically hinged inside the workbench 1. The sliding block 301 can slide horizontally through the rotating rod 302. The friction wheel 303 is rotatably installed on the side where the two sliding blocks 301 are close to each other, and the outer wall of the circumscribed ring 207 has a pair of notches for the friction wheel 303 to pass through.

[0023] Initially, the two friction wheels 303 pass through the gaps in the circumscribed ring 207 respectively. When the connecting frame 206 descends, it drives the two sliding blocks 301 to descend synchronously. Then, the two sliding blocks 301 contact the two rotating rods 302 respectively. The two rotating rods 302 are forced to rotate downward with the connection point of the workbench 1 as the center of the circle, and apply thrust to the corresponding sliding blocks 301 respectively. The two sliding blocks 301 are forced to slide away from each other and drive the friction wheels 303 to move. When the inscribed ring 205 contacts the circumscribed ring 207 and the foam board, there is a large gap between the two sliding blocks 301, and the two sliding blocks 301 and the two friction wheels 303 will not contact the foam board. This can prevent the foam board from being squeezed and deformed by the sliding blocks 301 and the friction wheels 303 when cutting the foam board, causing the cut foam product 100 to be deformed.

[0024] like Figure 4 and Figure 5As shown, the feeding mechanism also includes a round box 401, on which the round box 401 is rotatably mounted on the axle of the friction wheel 303, a coil spring is provided between the inner wall of the round box 401 and the axle of the friction wheel 303, and a friction plate 402 cooperating with the round box 401 is symmetrically fixedly mounted on the bottom of the connecting frame 206. When the round box 401 contacts the friction plate 402 and moves relative to the friction plate 402, the friction between the friction plate 402 and the round box 401 can cause the round box 401 to rotate.

[0025] like Figure 5 As shown, the feeding mechanism further includes a damping ring 501 . The damping ring 501 is sleeved on the axle of the friction wheel 303 . The damping ring 501 can apply damping to the axle of the friction wheel 303 . The damping ring 501 is fixedly connected to the sliding block 301 .

[0026] like Figure 4 As shown, a damping sleeve 601 is also included. The damping sleeve 601 is symmetrically fixedly installed on the workbench 1. The connecting frame 206 is slidably connected to the damping sleeve 601. When the connecting frame 206 slides, the damping sleeve 601 applies resistance to the connecting frame 206, enabling the connecting frame 206 to slide slowly.

[0027] Initially, the coil spring is in a released state. When the two friction wheels 303 move away from each other, the axle of the friction wheel 303 drives the round box 401 to move. The friction plate 402 applies friction to the outer wall of the round box 401 to make the round box 401 rotate. The round box 401 applies force to the axle of the friction wheel 303 through the coil spring. Under the action of the damping ring 501, the axle of the friction wheel 303 makes the friction wheel 303 rotate slowly. At this time, the rotation speed of the round box 401 is higher than the rotation speed of the axle of the friction wheel 303. The coil spring is further released and elastically stores force until the round box 401 is no longer in contact with the friction plate 402. The coil spring contracts and resets, driving the round box 401 to rotate. After completing the cutting of the foam product 100, the telescopic end of the first electric push rod 201 is controlled to contract. The telescopic end of the rod 201 drives the T-shaped rod 203 to rise through the lifting frame 202, and the T-shaped rod 203 drives the roller and the inner ring 205 to rise, and no longer squeezes the connecting frame 206. The connecting frame 206 elastically slides and rises, and the two damping sleeves 601 apply damping to the connecting frame 206, so that the connecting frame 206 rises slowly, and the connecting frame 206 drives the outer ring 207 to rise slowly upward. A gap is generated between the T-shaped rod 203 and the connecting frame 206, and the inner ring 205 is lifted upward relative to the outer ring 207. It is worth noting that the outer wall of the inner ring 205 is relatively smooth, and the inner wall of the outer ring 207 is relatively rough. When the outer ring 207 is lifted upward, the inner wall of the outer ring 207 applies friction to the foam product 100, so that the foam product 100 is lifted upward synchronously. The inner ring 205 does not exert friction on the foam product 100, and the foam product 100 can remain stable in the outer ring 207. Before the roller contacts the corner of the V-shaped rod 204, the inner ring 205 is no longer in contact with the foam product 100. The connecting frame 206 is lifted while driving the two sliding blocks 301 to lift upward. The two rotating rods 302 are gradually elastically released and rotated upward as the two sliding blocks 301 are lifted. The two sliding blocks 301 elastically contract and slide close to each other, driving the friction wheel 303 to move. When the roller of the T-shaped rod 203 passes the corner of the V-shaped rod 204, the T-shaped rod 203 gradually elastically releases and slides, driving the roller and the inner ring 205 to move to the left, and then the round box 401 contacts the adjacent friction plate 402. The friction plate 402 applies friction to the outer wall of the round box 401, causing the round box 401 to rotate. The round box 401 applies force to the axle of the friction wheel 303 through the coil spring. Under the action of the damping ring 501, the axle of the friction wheel 303 rotates slowly. At this time, the rotation speed of the round box 401 is higher than the rotation speed of the axle of the friction wheel 303, until the sliding block 301 slides and resets, causing the two friction wheels 303 to reset. The two friction wheels 303 fit the outer wall of the foam product 100, and the round box 401 stops rotating. The coil spring is gradually released to cause the friction wheels 303 to rotate. The two friction wheels 303 apply friction to the outer wall of the foam product 100, causing the foam product 100 to gradually lift upward in the circumscribed ring 207 until the coil spring is no longer released.The finished foam product 100 is no longer lifted, and the top of the finished foam product 100 now passes over the top of the circumscribed ring 207, so as to facilitate the subsequent shaping work on the top of the finished foam product 100.

[0028] like Figure 6 and Figure 7 As shown, a separation mechanism is also included, which includes a negative pressure air pump 701 installed in the workbench 1. The output end of the negative pressure air pump 701 is connected to an air pipe 702. One end of the air pipe 702 is connected to a special-shaped tube 703. A negative pressure box 704 is embedded and fixedly installed in the workbench 1. The special-shaped tube 703 is connected to the negative pressure box 704. The top of the negative pressure box 704 has a plurality of suction holes. The gaps between the plurality of suction holes are the same as the outline of the foam finished product 100.

[0029] After the foam product 100 is cut out, the negative pressure air pump 701 is controlled to generate negative pressure. The negative pressure air pump 701 generates suction through the air pipe 702 and the special-shaped tube 703 to make the several suction holes of the negative pressure box 704 generate suction, so that the waste of the foam board is adsorbed on the workbench 1 to prevent the waste of the foam board from being affected by the friction of the inner wall of the inner ring 205 or the outer wall of the outer ring 207 when the inner ring 205 and the outer ring 207 are lifted upward. As the gaps between the several suction holes are the same as the contour of the foam product 100, when the foam product 100 is lifted along with the outer ring 207, the suction of the several suction holes of the negative pressure box 704 will not affect the foam product 100.

[0030] like Figure 7 As shown, an adjustment component for adjusting the suction force of several suction holes of the negative pressure box 704 is provided in the special-shaped tube 703, and the adjustment component includes a sliding column 801 elastically slidably installed in the special-shaped tube 703, and a connecting rod 802 is fixedly installed on the left end of the sliding column 801. The left end of the connecting rod 802 slides through the special-shaped tube 703 and is fixedly installed with an adjustment block 803 that is slidably connected to the inner wall of the special-shaped tube 703.

[0031] When the density of the foam board is low, the internal air flow permeability of the foam board is good, and the external air flow can quickly enter the negative pressure box 704 through the foam board and the several air suction holes of the negative pressure box 704. The internal air pressure of the special-shaped tube 703 and the negative pressure box 704 will not affect the sliding column 801, and the sliding column 801 will not move. The suction force generated by the several air suction holes of the negative pressure box 704 on the foam board is sufficient to make the foam board waste stay on the workbench 1. When the density of the foam board is high, the internal air flow permeability of the foam board is poor, and the flow speed of the air flow in the foam board is slow. The external air flow cannot enter the negative pressure box 70 in time through the foam board and the several air suction holes of the negative pressure box 704. 4, at this time, the sliding column 801 slides to the right under the influence of the internal air pressure of the special-shaped tube 703 and the negative pressure box 704, and drives the adjustment block 803 to move through the connecting rod 802. After the adjustment block 803 moves, the air circulation on the inner wall of the special-shaped tube 703 is reduced, thereby reducing the suction force generated by the several suction holes of the negative pressure box 704. In this way, the suction force generated by the several suction holes of the negative pressure box 704 is automatically adjusted according to the density of the foam board, so as to facilitate the processing of foam boards with different densities. When the telescopic end of the first electric push rod 201 is reset, the negative pressure air pump 701 is controlled to no longer generate negative pressure, and then the feeding mechanism in the prior art is controlled to convey the foam board.

[0032] like Figures 8-10 As shown, it also includes a support rod 901, a support rod 901 located on the right side of the connecting frame 206 is fixedly installed in the workbench 1, and a lifting rod 902 sliding through the support rod 901 is fixedly installed on the right side of the bottom of the lifting frame 202. The top of the support rod 901 is hinged with a rotating frame 903, and a hemispherical block is fixedly installed in the rotating frame 903. The outer wall of the lifting rod 902 has a guide groove that cooperates with the hemispherical block. The guide groove consists of a vertical part and a spiral part. When the lifting rod 902 descends, it can squeeze the hemispherical block through the guide groove to rotate the rotating frame 903. A sliding rod 9031 that moves in the up and down directions is slidably installed on the rotating frame 903. The bottom end of the sliding rod 9031 is fixedly installed with a guide rail 904, and a compression spring is provided between the top of the guide rail 904 and the bottom of the rotating frame 903. An electric slider 905 is slidably installed in the guide rail 904, and a cutting resistance wire 906 for cutting the foam board is installed at the bottom of the electric slider 905.

[0033] Initially, the center of the guide rail 904 is aligned with the center of the circumscribed ring 207. When the lifting frame 202 descends, the lifting frame 202 drives the lifting rod 902 to descend. The spiral portion of the guide groove of the lifting rod 902 squeezes the hemispherical block of the rotating frame 903. The hemispherical block is forced to drive the rotating frame 903 to rotate counterclockwise with the connection point of the support rod 901 as the center. The rotating frame 903 drives the guide rail 904 to move through the sliding rod 9031, so that the guide rail 904 avoids the inscribed ring 205 to prevent the inscribed ring 205 from colliding with the guide rail 904 when descending. When the vertical portion of the guide groove of the lifting rod 902 contacts the hemispherical block of the rotating frame 903, the rotating frame 903 stops rotating. When the lifting frame 202 is lifted up, until the spiral portion of the guide groove of the lifting rod 902 contacts the hemispherical block of the rotating frame 903, The spiral portion of the guide groove of the lifting rod 902 squeezes the hemispherical block, causing the rotating frame 903 to rotate clockwise with the connection point of the support rod 901 as the center until the lifting frame 202 is reset and the lifting rod 902 no longer moves. The rotating frame 903 drives the guide rail 904 to reset, and then controls the cutting resistance wire 906 to heat. Subsequently, the foam product 100 is lifted up to contact with the cutting resistance wire 906 under the action of the two friction wheels 303. At this time, the electric slider 905 is controlled to slide along the guide rail 904. The electric slider 905 drives the cutting resistance wire 906 to move to cut the foam product 100 and shape the top of the foam product 100. When the electric slider 905 moves to the initial position, the electric slider 905 is controlled to stop moving, completing the shaping work of the foam product 100.

[0034] like Figure 10 As shown, it also includes a second electric push rod 1001 installed in the workbench 1, and a vertical frame 1002 is fixedly installed on the telescopic end of the second electric push rod 1001. A U-shaped frame that moves in the up and down directions is slidably installed in the vertical frame 1002, and a clamp 1003 is symmetrically installed at the bottom of the U-shaped frame. A horizontal axis located on the upper side of the rotating frame 903 is fixedly installed on the sliding rod 9031, and an extrusion rod 1004 that cooperates with the horizontal axis is symmetrically fixedly installed on the top of the vertical frame 1002. A V-shaped track 1005 located on the left side of the support rod 901 is fixedly installed in the workbench 1, and a sliding shaft that cooperates with the V-shaped track 1005 is fixedly installed on the right side of the U-shaped frame.

[0035] After the shaping of the finished foam product 100 is completed, the telescopic end of the second electric push rod 1001 is controlled to extend, and the telescopic end of the second electric push rod 1001 drives the vertical frame 1002 to move forward. The vertical frame 1002 drives the clamp 1003 and the slide shaft to move forward through the U-shaped frame, and drives the extrusion rod 1004 to move forward. The extrusion rod 1004 squeezes the horizontal axis of the slide bar 9031. The horizontal axis is subjected to force and drives the guide rail 904 to lift upward through the slide bar 9031. The compression spring is forced to shrink, and the guide rail 904 drives the cutting resistance wire 906 to lift upward through the electric slider 905, so that the cutting resistance wire 906 avoids the two clamps 1003 until the slide shaft slides to the corner of the V-shaped track 1005, controls the two clamps 1003 to clamp the foam product 100, and the vertical frame 1002 continues to move forward, thereby causing the slide shaft to lift obliquely upward along the V-shaped track 1005, and the slide shaft drives the two clamps 1003 through the U-shaped frame. Lifting upward, the two clamps 1003 clamp the foam product 100 and separate from the circumscribed ring 207 until the sliding shaft slides to the end of the V-shaped track 1005, then the two clamps 1003 are controlled to release the foam product 100, so that the foam product 100 falls into the prepared collection items, and then the telescopic end of the second electric push rod 1001 is controlled to retract, and the telescopic end of the second electric push rod 1001 drives the vertical frame 1002 to move backward, and the vertical frame 1002 drives the two clamps 1003 and the sliding shaft to move backward through the U-shaped frame, and drives the extrusion rod 1004 to move backward, and the sliding shaft gradually drives the U-shaped frame to descend along the V-shaped track 1005, and the U-shaped frame drives the two clamps 1003 to descend. As the extrusion rod 1004 moves backward, the compression spring is gradually released to drive the guide rail 904 to descend until the telescopic end of the second electric push rod 1001 is reset, and the guide rail 904 drives the cutting resistance wire 906 to descend and reset through the electric slider 905.

[0036] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will fall within the scope of the claims herein.
