Description

Technical Field

[0001] The present invention relates to the technical field of tube paper forming and processing, and in particular to a pollution-free green tube paper diversified forming structure with a mold that can be quickly switched. Background Art

[0002] As is well known, in the process of tube paper forming and processing, in order to achieve pollution-free processing, most use agricultural and forestry waste such as bamboo fiber, bagasse fiber, and wheat straw fiber as the main raw materials, which can reduce deforestation and carbon emissions. In the processing and forming of cylindrical tube paper, usually, the paper material is extruded at one end of the mold and formed and output at the other end.

[0003] In the existing tube paper forming and processing, especially when producing a large number of small batches, the sizes and shapes of the finished tube paper to be processed may vary, so the mold needs to be frequently replaced. In the prior art, most of the mold replacements are carried out through flanges. This method is relatively dependent on manual labor and the efficiency needs to be improved. When processing some large-diameter tube paper, due to the lack of support at the bottom, it sometimes sags and deforms during long-distance transportation to subsequent dehydration and other processes. Although it can be solved by auxiliary support, it is difficult to operate according to the formed tube paper of different sizes.

[0004] Based on the above-mentioned situations, we found that it is difficult to avoid the above situations simultaneously during the tube paper forming and processing of the prior art. Therefore, we propose a pollution-free green tube paper diversified forming structure with a mold that can be quickly disassembled and installed, and at the same time, molds of different sizes can be installed and used, and it can assist in supporting when outputting the formed tube paper. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides a pollution-free green tube paper diversified forming structure with a mold that can be quickly switched, which has the advantages of being able to quickly disassemble and install the mold, and at the same time, molds of different sizes can be installed and used, and it can assist in supporting when outputting the formed tube paper.

[0007] (2) Technical Solutions

[0008] The above technical object of the present invention is achieved by the following technical solutions: A pollution-free green tube paper diversified forming structure with a mold that can be quickly switched, including a frame and an outer support structure. Inside the frame, a front fixed frame and a rear fixed frame are fixedly connected. Inside the front fixed frame and the rear fixed frame, a front mold-changing ring and a rear mold-changing ring are respectively fixedly connected. Between the front mold-changing ring and the rear mold-changing ring, there is a ring mold sleeve. Inside the front mold-changing ring and the rear mold-changing ring, there are integrally formed connecting blocks. Inside the connecting blocks, connecting pins are rotatably connected. Inside the connecting pins, levers are rotatably connected. Outside the levers, claw jaws are rotatably connected. The ring mold sleeve is slidably connected to the outside of the rear mold-changing ring. On the front side of the ring mold sleeve, an adjustment pin is fixedly connected. Inside the lever, a chute for cooperating with the adjustment pin is opened. The inside of the chute is movably connected to the adjustment pin. Inside the frame, there is a mold body. The outside of the mold body is movably connected to the claw jaws. The rear side of the mold body is externally connected to the output pipe of a material pump.

[0009] By adopting the above technical solutions, the frame is provided to connect the structure and the forming equipment. The provided outer support structure is used to assist in supporting the formed tube paper. The provided front fixed frame and rear fixed frame are respectively used to fix the front mold-changing ring and the rear mold-changing ring. During normal use, the mold body is stuck between several claw jaws to limit and fix its position. When it is necessary to disassemble and replace the mold body, the ring mold sleeve can be rotated along the front fixed frame and the rear fixed frame. The connected adjustment pin slides inside the chute, and at the same time, the lever is pulled to rotate circumferentially along the connecting pin. During the rotation, the claw jaws connected to the lever will also change their positions inside the front mold-changing ring. Multiple claw jaws will approach or move away from the mold body synchronously, so as to facilitate the replacement of the mold body after disassembly. And when the ring mold sleeve is reversed, the claw jaws will be re-stuck outside the mold body again. This can not only quickly replace the mold body, but also install mold bodies with different diameters or external contours inside the frame.

[0010] The present invention is further provided as: Several card slots are opened on the surface of the mold body. On the side of the claw jaw close to the mold body, a contact pad is fixedly connected. The side of the claw jaw close to the card slot is in contact with the card slot.

[0011] By adopting the above technical solutions, the card slots are provided to cooperate with the claw jaws. When the inner diameter of the claw jaw and the outer diameter of the mold body cannot fit, the protruding part of the claw jaw can be embedded inside the card slot to complete the fixation. The provided contact pad increases the friction when the sizes of the claw jaw and the mold body fit, making the installation more stable.

[0012] The present invention is further configured as follows: the left side of the inner top and the right side of the inner bottom of the frame are both rotatably connected with telescopic cylinders, both sides of the ring mold sleeve are fixedly connected with force plates, and the telescopic ends of the telescopic cylinders are rotatably connected with the force plates.

[0013] By adopting the above technical solution, by setting a telescopic cylinder and a force-bearing plate, the force-bearing plate can be pushed or pulled synchronously by two telescopic cylinders on the inner side of the frame to rotate, so as to replace manual rotation of the ring die sleeve and fix the position of the ring die sleeve.

[0014] The present invention is further configured as follows: a limiting block is fixedly connected to the front side of the rear mold change ring, a limiting groove is opened on the inner side of the ring mold sleeve, and the inner side of the limiting groove is slidably connected to the limiting block.

[0015] The above technical solution is adopted to set a limiting block and a limiting groove to limit the installation position and activity trajectory of the ring die sleeve to prevent the structure from loosening or tilting.

[0017] The above technical solution is adopted, by setting a fixed ring to cooperate with the movable ring, which is used to install the driven frame and the active frame, and the wheel frame and the supporting roller connected by the driven frame and the active frame through the rotating pin are used to provide auxiliary support for the periphery of the formed tube paper that they contact, so as to reduce the downward deformation of its bottom before it is transmitted to the back-end process. According to the size of the formed tube paper, the movable ring can be close to or away from the fixed ring. At this time, the driven frame and the active frame rotate relative to the rotating pin to adjust the size of the interval between the multiple supporting rollers to match the size of the formed tube paper.

[0018] The present invention is further configured as follows: a torsion spring is fixedly connected to the outer side of the wheel frame, and a side of the torsion spring away from the wheel frame is rotatably connected to a rotating pin.

[0019] By adopting the above technical solution, a torsion spring is set to limit the position of the wheel frame, so that it is not easy to swing and cause failure to support normally. It also has a deformation range when subjected to force to avoid damage to the paper tube material.

The front side of the ring die sleeve 7 is fixedly connected with an adjusting pin 11. A chute for cooperating with the adjusting pin 11 is opened on the inner side of the lever 9. The inner side of the chute is movably connected with the adjusting pin 11. A die body 12 is arranged on the inner side of the frame 1. The outer side of the die body 12 is movably connected with the claw 10. The rear side of the die body 12 is externally connected to the output pipe of the material pump;

[0043] By setting the frame 1 for connecting the structure and the forming equipment, the front fixing frame 2 and the rear fixing frame 3 are set to fix the front die-changing ring 4 and the rear die-changing ring 5 respectively. During normal use, the die body 12 is clamped between several claws 10 to limit and fix its position. When it is necessary to disassemble and replace the die body 12, the ring die sleeve 7 can be rotated along the front fixing frame 2 and the rear fixing frame 3. The adjusting pin 11 connected thereto slides inside the chute, and at the same time, the lever 9 is pulled to rotate circumferentially along the connecting pin 8. During the rotation, the claws 10 connected to the lever 9 also change their positions inside the front die-changing ring 4. The multiple claws 10 will approach or move away from the die body 12 synchronously, so as to facilitate the replacement of the die body 12 after disassembly, and when the ring die sleeve 7 is reversed, the claws 10 are re-clamped outside the die body 12. It can not only quickly replace the die body 12, but also install the die body 12 with different diameters or outer contours inside the frame 1.

[0044] Among them, a number of card slots are provided on the surface of the die body 12. A contact pad is fixedly connected to one side of the claw 10 close to the die body 12. One side of the claw 10 close to the card slot is in contact with the card slot. By setting the card slot to cooperate with the claw 10, when the inner diameter of the claw 10 and the outer diameter of the die body 12 cannot fit, the protruding part of the claw 10 can be embedded inside the card slot to complete the fixation. The contact pad is set to increase the friction when the sizes of the claw 10 and the die body 12 fit, making the installation more stable. The left side of the inner top and the right side of the inner bottom of the frame 1 are both rotatably connected with a telescopic cylinder 13. Force plates 14 are fixedly connected to both sides of the ring die sleeve 7. The telescopic end of the telescopic cylinder 13 is rotatably connected to the force plate 14. By setting the telescopic cylinder 13 to cooperate with the force plate 14, the force plate 14 can be synchronously pushed or pulled to rotate inside the frame 1 to replace manual rotation of the ring die sleeve 7 and fix the position of the ring die sleeve 7. A limiting block 15 is fixedly connected to the front side of the rear die-changing ring 5. A limiting groove 16 is provided inside the ring die sleeve 7. The inside of the limiting groove 16 is slidably connected to the limiting block 15. By setting the limiting block 15 to cooperate with the limiting groove 16, it is used to limit the installation position and movement track of the ring die sleeve 7 to prevent the structure from loosening or tilting and shifting.

[0045] Working principle of this embodiment: First, place the mold body 12 inside the frame 1 so that the outer side of the mold body 12 is movably connected to the clamping jaws 10. The clamping jaws 10 hold the mold body 12 to complete the preliminary positioning. If the inner diameter of the clamping jaws 10 does not fit the outer diameter of the mold body 12, the protruding part of the clamping jaws 10 is embedded in the card slot on the surface of the mold body 12 for fixation. If the sizes fit, the contact pads on the clamping jaws 10 increase the friction force to make the installation more stable. Start the telescopic cylinders 13 on the left side at the top and the right side at the bottom inside the frame 1. The telescopic cylinders 13 push or pull the force-bearing plate 14 to drive the ring die sleeve 62 to rotate along the front fixing frame 2 and the rear fixing frame 3. When the ring die sleeve 7 rotates, the adjusting pins 11 on it slide in the chute inside the lever 9, pulling the lever 9 to rotate circumferentially around the connecting pin 8, and further moving the clamping jaws 10 inside the front die-changing ring 4. Multiple clamping jaws 10 move away from the mold body 12 synchronously, and then the mold body 12 can be disassembled and replaced. Put a new mold body 12 in, and operate the telescopic cylinders 13 in reverse to make the ring die sleeve 7 reverse, and the clamping jaws 10 approach and hold the outer side of the mold body 12 again to complete the installation of the new mold.

[0047] Reference Figure 1-8 , a pollution-free green tube paper diversified forming structure capable of quickly switching molds further includes an outer support structure 6. Among them, the outer support structure 6 includes a fixed ring 61 and a moving ring 62. The inner side of the fixed ring 61 is rotatably connected to a driven frame 63, and the inner side of the moving ring 62 is rotatably connected to a driving frame 64. The inner side of the driving frame 64 is fixedly connected to a rotating pin 66. The outer side of the rotating pin 66 is rotatably connected to the driven frame 63. The outer side of the rotating pin 66 is rotatably connected to a wheel frame 67, and the inner side of the wheel frame 67 is rotatably connected to a supporting wheel 65;

[0048] By setting the fixed ring 61 in cooperation with the moving ring 62, it is used to install the driven frame 63 and the driving frame 64, and the wheel frame 67 and the supporting wheel 65 connected by the rotating pin 66 between the driven frame 63 and the driving frame 64 are used to assist in supporting the periphery of the formed tube paper in contact, so as to reduce the situation that its bottom deforms downward before being transmitted to the subsequent process. According to the different sizes of the formed tube paper, the moving ring 62 can approach or move away from the fixed ring 61. At this time, the driven frame 63 and the driving frame 64 rotate relative to the rotating pin 66 to adjust the size of the interval between multiple supporting wheels 65, so as to facilitate matching the size of the formed tube paper.

[0049] Among them, the outer side of the wheel frame 67 is fixedly connected with a torsion spring 17, and the side of the torsion spring 17 away from the wheel frame 67 is rotatably connected with the rotating pin 66. By setting the torsion spring 17, it is used to limit the position of the wheel frame 67, so that it is not easy to swing and cannot be supported normally. There is also a deformation range when subjected to force to avoid damage to the paper tube material. The front side of the frame 1 is fixedly connected with a connecting frame, and the inner side of the connecting frame is fixedly connected to the fixed ring 61. The front side of the frame 1 is fixedly connected with a guide rail 18, and the inner side of the guide rail 18 is rotatably connected with a screw rod 19. The front side of the guide rail 18 is externally connected to the output end of the drive motor, and the outer side of the screw rod 19 is threadedly connected with a transmission block 23. The side of the transmission block 23 close to the moving ring 62 is fixedly connected to the moving ring 62. By setting the connecting frame to cooperate with the guide rail 18, it is convenient to fix the fixed ring 61. By setting the guide rail 18 to cooperate with the screw rod 19, when the external drive motor drives the screw rod 19 forward and reverse, the transmission fast threadedly connected thereto will also move horizontally along the guide rail 18. The movable ring 62 connected thereto is driven to move horizontally, so as to drive the structure to adjust its position. The front side of the frame 1 is fixedly connected to the limit strip 20, and the inner side of the limit strip 20 is slidably connected to the limit block 21. The limit block 21 is fixedly connected to the movable ring 62 on one side thereof close to the movable ring 62. The limit strip 20 is provided to cooperate with the limit block 21 to further limit the movement of the movable ring 62, so as to avoid the situation where only the top suspension is subjected to force and the tilting deformation occurs. The left side of the limit strip 20 is fixedly connected to an auxiliary tube 22, and an air flow hole is provided on the inner side of the auxiliary tube 22. The auxiliary tube 22 is externally connected to a fan device. By providing the auxiliary tube 22 to cooperate with the air flow hole, it is convenient to blow in air through the external fan device, and preliminarily air dry and shape the formed tube paper material passing through the inner side. The auxiliary tube 22 is composed of an inner tube and an outer tube, and a heating wire is provided between the inner tube and the outer tube. The heating wire is provided to heat the air flow passing through the inside of the auxiliary tube 22 to improve the pre-drying efficiency of the tube paper material.

[0050] Working principle of this embodiment: The fixed ring 61 is fixed by the connecting frame on the front side of the frame 1, and the movable ring 62 is connected to the screw rod 19 on the guide rail 18 through the transmission block 23. The external drive motor is started to drive the screw rod 19 to rotate forward and reversely, so that the transmission block 23 drives the movable ring 62 to move horizontally along the guide rail 18, and the distance between the movable ring 62 and the fixed ring 61 is preliminarily adjusted so that the support wheel 65 is roughly aligned with the outer position of the tube paper after forming. When the tube paper of different sizes passes through the external support structure 6, the outer periphery of the tube paper contacts the support wheel 65, and the wheel frame 67 is stressed. Rotating around the rotating pin 66, the driven frame 63 and the active frame 64 also rotate relatively, automatically adjusting the intervals between the multiple supporting wheels 65 so that the supporting wheels 65 fit closely to the outer periphery of the tube paper, and the torsion spring 17 limits the swing range of the wheel frame 67 to ensure stable support and avoid damage to the tube paper, turn on the external fan equipment, blow air into the auxiliary tube 22, turn on the heating wire between the inner and outer tubes of the auxiliary tube 22, heat the airflow and then act on the tube paper, and the airflow acts on the surface of the tube paper through the airflow holes on the inner side of the auxiliary tube 22 for preliminary air drying.
