Description

Technical Field

[0001] This invention belongs to the field of feed production equipment, specifically relating to a device for adjusting the through hole of a ring die. Background Technology

[0002] The ring die is a core wear component of flat or ring die pellet mills and biomass pellet forming machines. Its working principle involves using pressure rollers to force powdered material into the through-holes on the ring die surface. Under high pressure and high temperature, the material is cooked, shaped, and cut to form pellet products. The geometric parameters of the ring die's through-holes directly determine the pellet density, hardness, surface finish, and production energy consumption.

[0003] Chinese Patent CN108543986B, published on July 26, 2019, discloses a device for drilling holes in a ring die. The device includes a ring die, a fixing mechanism for the ring die, a drilling mechanism disposed on the fixing mechanism, and a rotating mechanism disposed on the top of the fixing mechanism for rotating the ring die. The ring die includes a ring die body and ring die fixing rings disposed at both ends of the ring die body. The ring die fixing rings are provided with uniformly distributed ring die fixing holes, and the ring die body is provided with a plurality of through holes. The fixing mechanism includes a fixing base, and a telescopic support plate is vertically disposed on one side of the fixing base.

[0004] The aforementioned application document utilizes the irregular shape of the nautilus cam to solve the drilling problem of staggered holes in the ring die. However, when the device is used to adjust the through hole for thicker and longer ring dies, the rapid rotation of the drill head compresses the ring die, and pressure is applied from the side of the ring die, which may cause the ring die to shift away from the drill head, thus affecting the through hole effect of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for adjusting the through hole of a ring die, solving the problems mentioned in the background section. To achieve the above objective, this invention is implemented through the following technical solution: A device for adjusting the through hole of a ring die, comprising an adjusting chamber, a rotatable rotating platform mounted inside the adjusting chamber, a telescopic platform movable in the vertical direction mounted on the top of the rotating platform, an electric telescopic rod mounted inside the adjusting chamber, a servo motor mounted on the side of the electric telescopic rod, a drill bit mounted on the output end side of the servo motor, and a pressing rod movable on the telescopic end side of the electric telescopic rod. A fixing groove is formed inside the adjusting chamber, and a support rod is connected to the side of the fixing groove via a spring. A transmission component for transmission is assembled between the pressing rod and the support rod. A transmission plate is fixedly connected to the side of the support rod, and a support plate is connected to the side of the transmission plate via a spring. A torsion spring rod with an internal torsion spring is rotatably connected to the side of the support plate. A preload rod is fixedly connected to the side of the torsion spring rod, and a pressure plate is assembled on the side of the transmission plate. The regulating chamber is equipped with an auxiliary support assembly and a grinding fluid injection assembly.

[0006] Preferably, the transmission component includes a fixed plate fixed to the inner wall of the adjustment chamber. A pressing block is connected to the bottom of the fixed plate via a spring, and a force-bearing rod is fixedly connected to the side of the pressing block. This device allows for initial restriction using a pre-pressure rod before drilling, followed by stable support of the ring die using a pressure plate, thus improving the subsequent drilling effect of the drill bit.

[0007] Preferably, the support rod is located at the bottom of the extrusion block, and the support rod is in contact with the extrusion block.

[0008] Preferably, the support plate has a through opening, the cross-sectional shape of which is adapted to the cross-sectional shape of the pressure plate.

[0009] Preferably, the auxiliary support assembly includes a transmission rod fixed to the side of the support rod, a gear slidably connected to the side of the adjustment chamber, a through-rotating rod rotatably connected inside the adjustment chamber, a gear 1 and a transmission rod 2 fixedly connected to the outer side of the rotating rod 1, the gear 1 meshing with the gear 1, and a pressing plate connected to the side of the transmission rod 2 via a fixing block. By setting up the auxiliary support assembly, the pressing plate rotates to the inner wall side of the ring die and provides a certain degree of support there, thereby further improving the stability of the ring die during the through-hole process.

[0010] Preferably, the rack is located at the top of the first transmission rod, and the rack and the first transmission rod are in a fixed state.

[0011] Preferably, when the auxiliary support component is in the activated state, the pressing plate is in contact with the inner wall of the ring mold.

[0012] Preferably, the grinding fluid injection assembly includes a bevel gear 1 connected to the drill bit drive. A fixed platform is mounted on the top of the telescopic end of the electric telescopic rod. A rotating rod 2 is rotatably connected to the bottom of the fixed platform. A bevel gear 2 and a gear 2 are fixedly connected to the outer side of the rotating rod 2, respectively. The bevel gear 2 meshes with the bevel gear 1. A through-hole rigid pipe is mounted on the inner side of the fixed platform. A delivery hose is mounted on the side of the rigid pipe. A pipe connector is rotatably connected to the bottom of the rigid pipe. A gear 3 is fixedly connected to the outer side of the pipe connector, meshing with the gear 2. A nozzle is mounted on the bottom of the pipe connector. A detachable protective cover is mounted on the side of the fixed platform. A through-hole groove is opened on the side of the protective cover. By configuring the grinding fluid injection assembly, the grinding fluid can be intermittently sprayed to the drill bit, improving the drilling efficiency while reducing grinding fluid waste.

[0013] Preferably, when the grinding fluid injection assembly is in the activated state, the nozzle remains at the top position of the drill bit.

[0014] The advantages of this application are: (1) The device for adjusting the through hole of the ring die, when adjusting the through hole on the ring die, activates the electric telescopic rod, drives the servo motor and the drill head to move to the side, and cooperates with the extrusion rod, fixing plate, spring one, extrusion block, force rod one, fixing groove, spring two, support rod, transmission plate, spring three, support plate and torsion spring rod, pre-pressure rod and pressure plate, so that the pre-pressure rod can be used to initially restrict the through hole, and then the pressure plate is used to stabilize the ring die, which improves the subsequent through hole effect of the drill head.

[0015] (2) When the force rod moves downward, the device for adjusting the through hole of the ring die, in conjunction with the transmission rod, the rack, the rotating rod, the gear, the transmission rod and the fixing block, causes the pressing plate to rotate to the inner wall side of the ring die and perform a certain degree of support operation there, thereby further improving the stability of the ring die in the through hole process.

[0016] (3) The device for adjusting the through hole of the ring die, when the drill head rotates, can intermittently spray grinding fluid to the drill head by cooperating with bevel gear one, fixed platform, rotating rod two, bevel gear two, gear two, hard pipe, conveying hose, pipe joint, gear three, nozzle, protective cover and through groove, thereby improving the through hole efficiency of the drill head and reducing the waste of grinding fluid.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, please refer to Figures 1-6A device for adjusting the through hole of a ring die includes an adjusting chamber 100. A rotatable rotating table 200 is installed inside the adjusting chamber 100. A telescopic table 300, movable in the vertical direction, is installed on the top of the rotating table 200. An electric telescopic rod 400 is installed inside the adjusting chamber 100. A servo motor 500 is mounted on the side of the electric telescopic rod 400. A drill head 600 is mounted on the side of the output end of the servo motor 500. A pressing rod 701, movable accordingly, is mounted on the side of the telescopic end of the electric telescopic rod 400. The ring die to be processed is placed on the telescopic table 300. The telescopic table 300 is started, causing the ring die placed on it to move upward. Subsequently, the electric telescopic rod 400 is activated, causing the servo motor 500 and the drill head 600 to move laterally. The pressing rod 701 mounted on the side of the telescopic end of the electric telescopic rod 400 moves synchronously.

[0021] The regulating chamber 100 has a fixed groove 706 inside. A support rod 708 is connected to the side of the fixed groove 706 by a second spring 707. A transmission component for transmission is assembled between the pressing rod 701 and the support rod 708. The transmission component includes a fixed plate 702 fixed to the inner wall of the regulating chamber 100. A pressing block 704 is connected to the bottom of the fixed plate 702 by a first spring 703. The support rod 708 is located at the bottom of the pressing block 704 and is in contact with the pressing block 704. A force-bearing rod 705 is fixedly connected to the side of the pressing block 704. When the pressing rod 701 moves, it can press the force-bearing rod 705, causing the force-bearing rod 705 to move downward. The force-bearing rod 705 in the moving state can drive the pressing block 704 fixedly connected to it to move downward. At this time, the pressing block 704 stretches the first spring 703 and moves downward a certain distance. A transmission plate 709 is fixedly connected to the side of the support rod 708. When the pressing block 704 moves, it can press the support rod 708. The pressed support rod 708 can stretch the spring 707 and move a certain distance. The moving support rod 708 can drive the transmission plate 709 fixedly connected to it to move.

[0022] A support plate 711 is connected to the side of the transmission plate 709 via a spring 710. A torsion spring rod 712 with an internal torsion spring is rotatably connected to the side of the support plate 711. A preload rod 713 is fixedly connected to the side of the torsion spring rod 712. A pressure plate 714 is mounted on the side of the transmission plate 709. A through opening is provided on the support plate 711, the cross-sectional shape of which matches the cross-sectional shape of the pressure plate 714. As the two transmission plates 709 move towards each other, the preload rod 713 first contacts the outer wall of the ring die, and then the pressure plate 714 passes through the opening on the support plate 711, further supporting the outer wall of the ring die and improving the subsequent through-hole effect of the drill bit 600.

[0023] In use, the ring die to be processed is placed on the telescopic table 300. The telescopic table 300 is started, causing the ring die placed on it to move upward. Then, the electric telescopic rod 400 is activated, driving the servo motor 500 and the drilling head 600 to move to the side. The extrusion rod 701, which is mounted on the side of the telescopic end of the electric telescopic rod 400, moves synchronously. The extrusion rod 701 in the moving state can extrude the force rod 705, causing the force rod 705 to move downward. The force rod 705 in the moving state can then drive the extrusion block 704, which is fixedly connected to it, to move downward. At this time, the extrusion block 704 stretches the spring 703 and moves downward a certain distance, so that the extrusion block 704 extrudes the support rod 708. The support rod 708, which is compressed, can stretch the spring 707 and move a certain distance. The support rod 708 in the moving state can then drive the transmission plate 709, which is fixedly connected to it, to move. The two transmission plates 709 move towards each other, and the transmission plate 709 in the moving state can drive the spring 710 and the support plate 71. 1. The torsion spring rod 712 and the preload rod 713 move synchronously. When the preload rod 713 contacts the outer wall of the ring die, it is restricted by the outer wall, thus initially restricting the ring die. As the transmission plate 709 continues to move, the preload rod 713 can rotate at a certain angle around the torsion spring rod 712. Subsequently, the support plate 711 contacts the outer wall of the ring die, and the support plate 711 stops moving. The transmission plate 709 can then compress the torsion spring rod 712. 10. The pressure plate 714 is moved, and the pressure plate 714 passes through the opening on the support plate 711 to further support the outer wall of the ring die. Then, the servo motor 500 is activated, which drives the drill head 600 to rotate and perform the corresponding drilling operation. After the drilling operation is completed, the electric telescopic rod 400 drives the servo motor 500 and the drill head 600 to reset, and the device can be reset. Then, the position of the ring die can be adjusted by the rotating table 200 and the telescopic table 300 to facilitate the next drilling operation.

[0024] Example 2, please refer to Figures 3-8 Based on Embodiment 1, the adjustment chamber 100 is internally equipped with an auxiliary support assembly 800, which includes a transmission rod 801 fixed to the side of the support rod 708. When the force-bearing rod 705 moves downward, it can drive the transmission rod 801 fixedly connected to it to move downward.

[0025] A rack 802 is slidably connected to the side of the regulating chamber 100. The rack 802 is located at the top of the transmission rod 801, and the rack 802 and the transmission rod 801 are fixed together. When the transmission rod 801 moves downward, it can drive the rack 802, which is fixedly connected to it, to move downward together.

[0026] The regulating chamber 100 has a through-type rotating rod 803 internally connected. A gear 804 and a transmission rod 805 are fixedly connected to the outer side of the rotating rod 803. The gear 804 meshes with a rack 802. When the rack 802 moves downwards, as... Figure 7 As shown, the rack 802 in the downward moving state can drive the gear 804 meshing with it to rotate counterclockwise by a certain angle, so that the gear 804 drives the rotating rod 803 fixedly connected to it to rotate, and the rotating rod 803 in the rotating state can drive the transmission rod 805 fixedly connected to it to rotate.

[0027] A pressing plate 807 is connected to the side of the transmission rod 805 via a fixing block 806. When the auxiliary support assembly 800 is in operation, the pressing plate 807 is in contact with the inner wall of the ring die. When the transmission rod 805 rotates, it drives the fixing block 806, which is fixedly connected to it, to rotate synchronously. This causes the fixing block 806 to drive the pressing plate 807, which is fixedly connected to it, to rotate. The pressing plate 807 then rotates to the inner wall of the ring die, providing additional support at that point, thereby further improving the stability of the ring die during the through-hole process.

[0028] In use, based on Embodiment 1, when the force-bearing rod 705 moves downward, it can drive the transmission rod 801 fixedly connected to it to move downward, so that the transmission rod 801 drives the gear rod 802 fixedly connected to it to move downward together, such as... Figure 7 As shown, the rack 802 in the downward moving state can drive the gear 804 meshing with it to rotate counterclockwise by a certain angle, so that the gear 804 drives the rotating rod 803 fixedly connected to it to rotate. The rotating rod 803 in the rotating state can drive the transmission rod 805 fixedly connected to it to rotate, so that the transmission rod 805 drives the fixed block 806 fixedly connected to it to rotate synchronously, so that the fixed block 806 drives the pressing plate 807 fixedly connected to it to rotate. The pressing plate 807 then rotates to the inner wall of the ring mold to provide additional support at that point.

[0029] Example 3, please refer to Figures 7-9Based on Embodiments 1 and 2, a grinding fluid injection assembly 900 is installed inside the regulating chamber 100. The grinding fluid injection assembly 900 includes a bevel gear 901 that is driven by the drill head 600. A fixed platform 902 is installed at the top of the telescopic end of the electric telescopic rod 400. A rotating rod 903 is rotatably connected to the bottom of the fixed platform 902. A bevel gear 904 and a gear 905 are fixedly connected to the outer side of the rotating rod 903, respectively. The bevel gear 904 meshes with the bevel gear 901. When the drill head 600 rotates, it drives the bevel gear 901, which in turn drives the bevel gear 904, which in turn drives the rotating rod 903, which in turn drives the gear 905, which in turn rotates.

[0030] A through rigid pipe 906 is fitted inside the fixed platform 902, and a conveying hose 907 is fitted to the side of the rigid pipe 906. A pipe connector 908 is rotatably connected to the bottom of the rigid pipe 906, and a gear 909 is fixedly connected to the outside of the pipe connector 908. The gear 909 meshes with a gear 905. When the gear 905 rotates, it drives the meshing gear 909 to rotate, which in turn drives the fixedly connected pipe connector 908 to rotate.

[0031] A nozzle 910 is mounted at the bottom of the pipe connector 908. When the grinding fluid injection assembly 900 is in operation, the nozzle 910 remains at the top of the drill head 600. A removable protective cover 911 is mounted on the side of the mounting platform 902, and a through-hole groove 912 is provided on the side of the protective cover 911. When the pipe connector 908 rotates, it drives the nozzle 910 mounted at its bottom to rotate. At this time, grinding fluid is introduced through the delivery hose 907, and the grinding fluid in the delivery hose 907 is injected into the pipe connector 908 through the rigid pipe 906. When the nozzle 910 rotates to the through-hole groove 912 on the protective cover 911, the grinding fluid can be sprayed directly from there to the drill head 600. In this way, the grinding fluid can be sprayed intermittently to the drill head 600, improving the through-hole efficiency of the drill head 600 while reducing the waste of grinding fluid.

[0032] In use, based on Embodiments 1 and 2, when the drill bit 600 rotates, it drives the bevel gear 901 connected to it to rotate, causing the bevel gear 901 to drive the bevel gear 904 meshing with it to rotate. The rotating bevel gear 904 then drives the rotating rod 903 fixedly connected to it to rotate, causing the rotating rod 903 to drive the gear 905 fixedly connected to it to rotate. The rotating gear 905 then drives the gear 909 meshing with it to rotate, causing the gear 909 to rotate. 909 drives the pipe joint 908 fixedly connected to it to rotate, and the rotating pipe joint 908 can drive the nozzle 910 assembled at its bottom to rotate; at this time, grinding fluid is introduced through the delivery hose 907, and the grinding fluid in the delivery hose 907 can be injected into the pipe joint 908 through the rigid pipe 906. When the nozzle 910 rotates to the through groove 912 on the protective cover 911, the grinding fluid can be sprayed directly from there to the drill head 600; in this way, the grinding fluid can be sprayed intermittently to the drill head 600.
