[0010] By adopting the above-mentioned technical solution, through the arrangement of the electromagnetic ring and the magnetic block, by energizing the electromagnetic ring, the electromagnetic ring is magnetically attracted to the magnetic block, so that the screen plate can be detachably installed on the bottom wall of the cloth head, thereby improving the convenience of disassembly and assembly of the screen plate; on the other hand, by arranging multiple positioning blocks, the multiple positioning blocks are used to abut against the outer peripheral wall of the cloth head, and the positioning blocks can play a positioning effect, so that the screen plate and the cloth head can be kept aligned, thereby improving the installation accuracy of the screen plate.

[0011] Optionally, the upper surface of the mesh plate is provided with a plurality of positioning blocks that abut against the outer peripheral wall of the cloth head, and each of the positioning blocks is provided with a first limit groove on the side wall close to the cloth head, and the lower end outer peripheral wall of the cloth head is provided with a plurality of second limit grooves corresponding to the first limit groove; the disassembly and assembly assembly includes a limit block, a limit spring and a disassembly part, the limit block is slidably installed in the first limit groove, and the side wall of the limit block close to the cloth head has a first guide surface for moving the limit block toward the side away from the cloth head; the limit spring is installed between the limit block and the first limit groove, and the limit spring normally causes the limit block to be inserted into the second limit groove; the disassembly part is provided on the replacement turntable, and when the mesh plate of the cloth head moves to abut against the bottom wall of the replacement slot, the disassembly part forces the limit block to disengage from the second limit groove.

[0012] By adopting the above-mentioned technical solution, through the limit block, the limit spring and the disassembly part, when the screen plate is connected to the cloth head, the cloth head is driven to move toward the side close to the replacement slot (moving downward), and the cloth head can push the limit block through the first guide surface, forcing the limit block to move into the first limit slot. When the cloth head moves down to against the screen plate, the limit block is inserted into the second limit slot under the action of the limit spring, so that the screen plate is installed on the bottom wall of the cloth head; when the screen plate is replaced, the cloth head is driven down and forced to move into the replacement slot, and then the limit block is driven out of the second limit slot through the disassembly part, so that the screen plate can be separated from the cloth head, thereby improving the convenience of disassembly and assembly of the screen plate.

[0013] Optionally, a lifting plate for abutting against the mesh plate is slidably installed in the replacement slot, a return spring is arranged between the lifting plate and the replacement slot, a disassembly slot connected to the first limit slot is opened on the lower surface of the mesh plate, and the limit block has a second guide surface close to the side wall of the disassembly slot; the disassembly part includes a first push rod and a second push rod, the first push rod is slidably installed in the disassembly slot, one end of the second push rod is fixed to the bottom wall of the replacement slot, and the other end is passed through the lifting plate and abutted against the first push rod, when the mesh plate moves to abut against the lifting plate and continues to move downward, the second push rod abuts against the second guide surface through the first push rod, and drives the limit block to disengage from the second limit slot through the second guide surface.

[0014] By adopting the above-mentioned technical solution, through the setting of the first push rod and the second push rod, when the mesh plate of the cloth head is replaced, the cloth head is driven to move downward and the mesh plate is forced to abut against the lifting plate. At this time, the first push rod and the second push rod abut against each other, and continue to drive the cloth head downward. The mesh plate can push the lifting plate downward to force the reset spring to contract. The first push rod can force the limit block to move toward the side away from the cloth head through the second guide surface, so that the limit block is disengaged from the second limit groove, thereby separating the mesh plate from the cloth head, thereby improving the convenience of disassembly of the mesh plate.

[0015] Optionally, a workbench is further included, and the replacement turntable is rotatably mounted on the upper surface of the workbench, and a rotating ring groove is provided on the upper surface of the workbench, and the axial direction of the rotating ring groove is arranged to coincide with the axial direction of the replacement turntable; the reset spring normally makes the upper surface of the lifting plate lower than the upper surface of the replacement turntable, and the lower surface of the lifting plate is provided with an ejector rod, and the end of the ejector rod away from the lifting plate passes through the replacement turntable and extends to the rotating ring groove, and the rotating ring groove is provided with a guide block, and the guide block has a guide surface for ejecting the ejector rod toward the side away from the workbench.

[0016] By adopting the above-mentioned technical solution and arranging the ejector rod and the guide block, the replacement turntable is driven to rotate after the screen plate of the cloth head is disassembled. During the rotation of the replacement turntable, the ejector rod is driven to rotate along the rotating ring groove. When the ejector rod rotates to abut against the guide surface of the guide block, the guide surface can force the ejector rod to be ejected outward toward one side of the workbench, thereby forcing the lifting plate to push the screen plate out of the replacement slot to facilitate the removal of the screen plate, thereby further improving the convenience of screen plate disassembly.

[0017] Optionally, a guide bar is provided on the top of the replacement turntable, and the guide bar has a guide surface for the mesh plate to abut against. When the ejection rod is ejected outward and the replacement turntable continues to rotate, the mesh plate is guided out of the upper surface of the replacement turntable along the guide surface of the guide bar.

[0018] By adopting the above-mentioned technical solution and setting the guide bar, after the screen is pushed out of the replacement slot by the lifting plate, the replacement turntable continues to be driven to rotate. Driven by the replacement turntable, the screen is abutted against the guide surface of the guide bar and can be guided along the guide surface to the upper surface of the replacement turntable to facilitate the removal of the screen.

[0019] Optionally, the storage rack has a storage channel for storing mesh panels, and the discharge port is connected to the bottom of the storage channel; a plurality of positioning grooves are provided on the outer peripheral wall of the mesh panel, and a plurality of positioning strips corresponding to the positioning grooves are provided in the storage channel, and both ends of the positioning strips extend along the height direction, and the positioning strips are inserted into the corresponding positioning grooves, and the mesh panel is slidably installed in the storage channel through the positioning strips.

[0020] By adopting the above-mentioned technical solution, through the setting of the positioning strips and the positioning slots, the storage channel is used to place the screen to be replaced, the screen is placed in the storage channel, and the positioning strips are inserted into the positioning slots of the screen. The screen falls to the bottom of the storage channel along the length direction of the positioning strips under the action of its own gravity, and the screen that falls to the bottom of the storage channel is pushed to the replacement slot by the loading piece, thereby transferring the screen to the replacement slot of the replacement turntable. The positioning strips and the positioning slots cooperate to limit the orientation of the screen, ensuring that the screen is transferred to the correct orientation of the replacement slot, so that the mesh holes on the screen can face the air pump vent of the cloth head, thereby improving the installation accuracy between the screen and the cloth head.

[0021] Optionally, the loading part includes a loading arc plate and a loading cylinder. The loading arc plate is slidably installed at the bottom of the storage channel. A first positioning block is fixed on the inner arc surface of the loading arc plate. The first positioning block is used to match and be inserted in the positioning groove. The loading cylinder is connected to the loading arc plate to drive the loading arc plate close to or away from the replacement turntable.

[0022] By adopting the above-mentioned technical solution, through the setting of the loading arc plate and the loading cylinder, the piston rod of the loading cylinder is driven to extend or retract, which can drive the loading arc plate close to or away from the replacement turntable. In the process of the loading arc plate pushing the screen plate to transfer, the first positioning block is inserted into the positioning groove of the screen plate to limit the screen plate, thereby reducing the possibility of the screen plate being freely offset during the transfer process, resulting in the orientation error of the screen plate.

[0023] Optionally, the replacement slot passes through the peripheral wall of the replacement turntable for the mesh plate to enter, and the inner wall of the replacement slot is provided with a second positioning block for being inserted into the positioning slot; the replacement slot is provided with a reinforcement for keeping the second positioning block inserted into the positioning slot.

[0024] By adopting the above-mentioned technical solution, through the arrangement of the second positioning block and the reinforcement, after the mesh plate is transferred from the storage channel to the replacement slot of the replacement turntable, the second positioning block is inserted into the positioning slot of the mesh plate, and the reinforcement is used to keep the second positioning block inserted in the positioning slot to limit the mesh plate, thereby reducing the possibility of the mesh plate rotating freely and causing the orientation of the mesh plate to be wrong during the rotation of the mesh plate driven by the replacement turntable, thereby ensuring that after the fabric head is connected to the mesh plate in the replacement slot, the mesh holes on the mesh plate can face the air pump vent of the fabric head.

[0025] Optionally, an installation groove is provided on the inner wall of the replacement groove, and the installation groove and the second positioning block are arranged axially at intervals around the mesh plate; the reinforcement includes an elastic strip arranged in the installation groove, and the elastic strip has a limiting portion for being inserted into the positioning groove, and the positioning groove in which the second positioning block is inserted and the positioning groove in which the limiting portion is inserted are set differently. When the second positioning block is inserted into the corresponding positioning groove, the elastic strip is deformed and the limiting portion is inserted into the corresponding positioning groove.

[0026] By adopting the above-mentioned technical solution and setting the elastic strip, when the mesh plate is transferred to the replacement slot under the action of the loading piece, the outer wall of the mesh plate pushes the elastic strip and forces the limiting part of the elastic strip to deform. As the mesh plate continues to move, when the second limiting block is inserted into the corresponding positioning slot, the limiting part recovers its deformation and is inserted into the corresponding positioning slot. The positioning slot inserted by the second positioning block and the positioning slot inserted by the limiting part are set to be different, thereby limiting the mesh plate, so that the second positioning block remains inserted in the positioning slot, and the connection stability between the mesh plate and the replacement slot is improved.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a replacement turntable and a storage rack, the storage rack is used to place the screen plate to be replaced (new screen plate). When the screen plate (old screen plate) on the cloth head needs to be replaced, the cloth head is moved to the top of the replacement turntable and driven to move downward so that the old screen plate is against the bottom wall of the replacement slot. At this time, the old screen plate is separated from the cloth head by the disassembly and assembly component; then the cloth head is driven to lift up the replacement slot and push the new screen plate in the storage rack to the replacement slot through the loading part, and the replacement turntable is driven to rotate, and the new screen plate is rotated to the bottom of the cloth head and the old screen plate is moved out from under the cloth head; then the cloth head is driven downward and the new screen plate is installed on the cloth head through the disassembly and assembly component. Multiple replacement slots can make the new screen plate put in and the old screen plate taken out simultaneously without switching to the shutdown state, which greatly improves the replacement efficiency of the screen plate and thus improves the processing efficiency of the diamond cutter head;

[0029] 2. Through the limit block, limit spring and disassembly part, when the screen plate is connected to the cloth head, the cloth head is driven to move toward the side close to the replacement slot (downward), and the cloth head can push the limit block through the first guide surface, forcing the limit block to move into the first limit slot. When the cloth head moves down to contact the screen plate, the limit block is inserted into the second limit slot under the action of the limit spring, so that the screen plate is installed on the bottom wall of the cloth head; when the screen plate is replaced, the cloth head is driven down and forced to move into the replacement slot. The limit block is driven out of the second limit slot by the disassembly part, so that the screen plate can be separated from the cloth head, thereby improving the convenience of disassembly and assembly of the screen plate;

[0030] 3. Through the setting of the positioning strips and the positioning slots, the storage channel is used to place the mesh plate to be replaced. The mesh plate is placed in the storage channel, and the positioning strips are inserted into the positioning slots of the mesh plate. The mesh plate falls to the bottom of the storage channel along the length direction of the positioning strips under the action of its own gravity. The mesh plate that falls to the bottom of the storage channel is pushed to the replacement slot by the loading piece, thereby transferring the mesh plate to the replacement slot of the replacement turntable. The positioning strips and the positioning slots cooperate to limit the orientation of the mesh plate, ensuring that the mesh plate is transferred to the correct orientation of the replacement slot, so that the mesh holes on the mesh plate can face the air pump vent of the cloth head, thereby improving the installation accuracy between the mesh plate and the cloth head.

[0063] Example 2:

[0064] The embodiment of the present application discloses a screen plate replacement device for a uniform distribution device.

[0065] Reference Figure 8 、 Figure 9 The difference between the screen plate replacement device for uniform distribution equipment disclosed in the embodiment of the present application and embodiment 1 is that:

[0066] When the cam 31 is in the unlock position, the cam 32 is in the unlock position, and the lock 32 is in the unlock position, so that the cam 32 is locked.

[0067] Reference Figure 8 、 Figure 9 、 Figure 10 Each positioning block 21 is provided with a first limiting groove 211 on the side wall close to the cloth head 1, and a plurality of second limiting grooves 13 are provided on the outer peripheral wall of the lower end of the cloth head 1, and all the second limiting grooves 13 are arranged corresponding to all the first limiting grooves 211; in this embodiment, the disassembly and assembly components 5 are provided with multiple groups and are arranged corresponding to the multiple positioning blocks 21.

[0068] Reference Figure 9 、 Figure 10 The disassembly and assembly component 5 includes a limit block 53, a limit spring 54 and a disassembly part 55. The limit block 53 is slidably installed in the first limit groove 211. The side wall of the limit block 53 close to the cloth head 1 has a first guide surface 531. The first guide surface 531 is used to move the limit block 53 toward the side away from the cloth head 1; one end of the limit spring 54 is fixedly connected to the inner wall of the first limit groove 211, and the other end is fixedly connected to the limit block 53. The limit spring 54 often makes the limit block 53 partially exposed in the first limit groove 211 and inserted in the second limit groove 13.

[0069] Reference Figure 9 The disassembly part 55 is arranged on the replacement turntable 3. When the screen plate 2 moves to abut against the bottom wall of the replacement slot 31 (that is, the screen plate 2 pushes the lifting plate 32 and forces the lifting plate 32 to abut against the bottom wall of the replacement slot 31), the disassembly part 55 forces the limit block 53 to disengage from the second limit slot 13.

[0070] Reference Figure 9 、 Figure 10When the cam 53 is in the unlock state, the second push rod 552 is in the unlock state, and the second push rod 552 is in the unlock state, so that the cam 53 is locked.

[0071] Reference Figure 9 、 Figure 11 , a rotating ring groove 61 is provided on the upper surface of the workbench 6, and the axial direction of the rotating ring groove 61 coincides with the axial direction of the replacement turntable 3; an ejector rod 34 is fixedly installed on the lower surface of the lifting plate 32, and the ejector rod 34 is vertically arranged. The lower end surface of the ejector rod 34 passes through the replacement turntable 3 and extends to the rotating ring groove 61. When the lifting plate 32 abuts against the bottom wall of the replacement slot 31, the lower end surface of the ejector rod 34 abuts against the bottom wall of the rotating ring groove 61; the rotating ring groove 61 is fixed A guide block 62 is fixedly installed, and the guide block 62 has a guide surface 621 for pushing the ejection rod 34 toward the side away from the workbench 6; it should be noted that after the mesh plate 2 (old mesh plate 2) of the cloth head 1 is removed from the replacement slot 31, the replacement turntable 3 is rotated to rotate the new mesh plate 2 to the bottom of the cloth head 1 and rotate the old mesh plate 2 out from under the cloth head 1. During the process of rotating the old mesh plate 2 out, the ejection rod 34 abuts against the guide block 62 to eject the old mesh plate 2 outward.

[0072] Reference Figure 9 A magnet block 341 is fixed to the outer peripheral wall of the ejector rod 34, and a magnet ring 611 is fixed to the inner wall of the rotating ring groove 61. When the lower end surface of the ejector rod 34 abuts against the bottom wall of the rotating ring groove 61, the magnet block 341 and the magnet ring 611 are magnetically attracted to each other.

[0073] When the cam 32 is in the working state, the cam 32 is in the working state, and the cam 32 is in the working state, so that the cam 32 is in the working state, and the cam 32 is in the working state, so that the cam 32 is in the working state, and the cam 32 is in the working state, so that the cam 32 is in the working state, and the cam 32 is in the working state, so that the cam 32 is in the working state, and the cam 32 is in the working state.

[0074] The implementation principle of Example 2 of the present application is as follows: when the mesh plate 2 of the cloth head 1 is disassembled, the cloth head 1 is moved so that the old mesh plate 2 on the cloth head 1 moves down to abut against the lifting plate 32, and downward pressure is continued to be applied to force the lifting plate 32 to abut against the bottom wall of the replacement slot 31. At this time, the ejection rod 34 abuts against the bottom wall of the rotating ring groove 61 and causes the magnet block 341 and the magnet ring 611 to be magnetically attracted to each other, and the limit block 53 is disengaged from the second limit groove 13 under the action of the first ejection rod 34, and then the cloth head 1 is lifted to separate the cloth head 1 and the old mesh plate 2 from each other.

[0075] When the new mesh plate 2 is installed, the new mesh plate 2 is pushed to the replacement slot 31 and the replacement turntable 3 is rotated, forcing the new mesh plate 2 to rotate to the bottom of the cloth head 1 and the old mesh plate 2 to rotate out from the bottom of the cloth head 1. During the rotation of the replacement turntable 3, the ejector rod 34 moves upward under the action of the guide block 62, forcing the magnet block 341 and the magnet ring 611 to interact with each other, thereby pushing the old mesh plate 2 out of the replacement slot 31 to facilitate the removal of the old mesh plate 2; after the new mesh plate 2 rotates to the bottom of the cloth head 1, the cloth head 1 is driven downward, and the outer peripheral wall of the cloth head 1 pushes the limit block 53 away through the first guide surface 531. When the cloth head 1 moves down to abut against the upper surface of the new mesh plate 2, the limit block 53 is inserted into the second limit slot 13 under the action of the limit spring 54, completing the installation of the new mesh plate 2, greatly improving the convenience of disassembly and installation of the mesh plate 2, and improving the working efficiency of the overall structure.

[0076] Example 3:

[0077] The embodiment of the present application discloses a screen plate replacement device for a uniform distribution device.

[0078] Reference Figure 12 The difference between the screen plate replacement device for uniform distribution equipment disclosed in the embodiment of the present application and embodiment 2 is that:

[0079] In this embodiment, a guide strip 7 is installed on the upper surface of the workbench 6. The guide strip 7 is located on the top of the replacement turntable 3, and one end of the guide strip 7 extends out of the upper surface of the replacement turntable 3. The guide strip 7 is arc-shaped and forms a guide surface 71 for the mesh plate 2 to abut against. When the ejection rod 34 ejects the old mesh plate 2 outward under the action of the guide block 62 and the replacement turntable 3 continues to rotate, the old mesh plate 2 is guided out of the upper surface of the replacement turntable 3 along the guide surface 71 of the guide strip 7.

[0080] The implementation principle of Example 3 of the present application is as follows: the ejection rod 34 is ejected outward under the action of the guide surface 621 of the guide block 62, so that the lifting plate 32 can push the old mesh plate 2 out of the replacement slot 31. As the replacement turntable 3 continues to rotate, the replacement turntable 3 drives the old mesh plate 2 to abut against the guide surface 71 of the guide bar 7, so that the old mesh plate 2 can be guided out of the upper surface of the replacement turntable 3 along the guide surface 71, so that the old mesh plate 2 can be taken out in time, thereby improving the operational convenience of the overall structure.

[0081] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
