Abstract
Description
Technical Field
[0001] This application relates to the field of clay toy production, and in particular to a clay extrusion and slitting apparatus. Background Technology
[0002] In the production process of clay toys, the continuous long strips of clay raw material (hereinafter referred to as raw material) extruded by the clay extruder need to be cut. The purpose is to cut the long strips of raw material into small pieces of a predetermined size to facilitate the next production process (such as embossing and boxing), which is an important step in the production of clay toys.
[0003] A slitting module for clay toy production is provided, wherein a conveying module is installed at the discharge port of a clay extruder, and the slitting module is mounted on the conveying module. The conveying module transports the raw material discharged from the extrusion port of the clay extruder to the area below the slitting module. The slitting module includes a drive cylinder and a cutter fixed to the output shaft of the drive cylinder. The drive cylinder drives the cutter to cut the raw material located on the conveying module.
[0004] However, in practical applications, the inventors discovered that during the process of the drive cylinder driving the cutter to cut the raw material located on the conveying module, the cutter moves linearly along the conveying module. The problem is that, due to the inherent characteristics of clay toys, after the cutter cuts the raw material, the two adjacent pieces of raw material are subjected to vibration and their own characteristics, resulting in some areas of the cut surface of the two adjacent pieces of raw material sticking together again. It is necessary to manually or through other mechanical structures to completely cut the two pieces of raw material, resulting in low cutting efficiency and a large quality deviation between the two adjacent pieces of raw material. There is room for improvement. Utility Model Content
[0005] The purpose of this utility model is to provide a clay extrusion slitting device to facilitate the slitting of raw materials after extrusion from a clay extruder.
[0006] To achieve the above objectives, the clay extrusion and slitting device provided in this application adopts the following technical solution:
[0007] A clay extrusion slitting device includes a frame and a conveyor belt rotatably supported on the frame. One end of the conveyor belt is connected to a clay extruder, and a slitting mechanism is provided at the end of the conveyor belt away from the clay extruder. The slitting mechanism includes a drive assembly, a transmission assembly, and a slitting blade. The transmission assembly includes a first base, a first swing arm, and a second swing arm. The first base is disposed on the frame, the first swing arm is rotatably connected to the first base, the second swing arm is rotatably connected to the first swing arm, and the second swing arm is movably connected to the slitting blade. The drive assembly is connected to the slitting blade. When the drive assembly drives the slitting blade to slit the raw material located on the conveyor belt, the slitting blade synchronously drives the second swing arm to swing along the first swing arm.
[0008] Preferably, the drive assembly includes a servo motor, a rotary wheel, and a swing arm. The servo motor is mounted on the frame. The rotary wheel is coaxially fixed with the output shaft of the servo motor. The rotary wheel has a rotating shaft on a surface off-center. One end of the swing arm along the length direction is rotatably connected to the rotating shaft, and the other end of the swing arm along the length direction is rotatably connected to the slitting blade.
[0009] Preferably, the second swing arm is provided with a guide plate, the guide plate is provided with a guide groove along the height direction, and the slitting blade slides in cooperation with the guide groove.
[0010] Preferably, the first base is provided with a guide member, and the guide member has an arc-shaped waist groove, and the end of the first swing rod away from the first base slides and engages with the arc-shaped waist groove.
[0011] Preferably, the first swing arm has a clearance groove, and the swing arm is located in the clearance groove.
[0012] Preferably, two sets of preliminary shaping components are provided on the frame located below the first base. The two sets of preliminary shaping components are symmetrically arranged about the centerline of the conveyor belt along the width direction. Each preliminary shaping component includes a drive cylinder and a shaping die. The shaping die is fixedly connected to the piston rod of the drive cylinder. When the slitting knife cuts the raw material, the piston rod of the drive cylinder drives the shaping die to simultaneously shape the raw material located between the slitting knife and the clay extruder.
[0013] Preferably, the frame is provided with a thickness adjustment assembly, which includes an adjustment block, a limiting roller, and a handle bolt. The limiting roller is rotatably connected to the adjustment block. The frame is provided with a limiting groove through it along the thickness direction. The adjustment block is inserted into the limiting groove. The handle bolt is threaded through the frame along the side wall of the frame and extends into the limiting groove. When the adjustment block is located in the limiting groove, the handle bolt abuts against the adjustment block.
[0014] Compared with the prior art, the present invention provides a clay extrusion and slitting device, which has the following beneficial effects:
[0015] 1. When it is necessary to cut the raw material on the conveyor belt, the drive assembly drives the cutting blade to move. Since the second swing arm is movably connected to the cutting blade, while the drive assembly drives the cutting blade to move, the second swing arm will swing along the first swing arm due to the force applied by the cutting blade. Since the first swing arm is movably connected to the first base, the first swing arm will also swing along the second swing arm. Thus, while the cutting blade cuts the raw material on the conveyor belt and moves away from the surface of the conveyor belt, the second swing arm, in conjunction with the first swing arm, drives the cutting blade to swing horizontally along the conveyor belt. At this time, since the conveyor belt is in motion, the cutting blade increases the distance between two adjacent pieces of raw material through the blocking effect of the cutting blade, so as to force the two adjacent pieces of raw material to separate. The separation operation and the cutting operation are synchronized, resulting in high cutting efficiency. This plays a positive guiding role in improving the efficiency of cutting the raw material after it is extruded from the clay extruder.
[0016] 2. Because the guide plate has a guide groove, the movement path of the slitting knife along the height of the frame is limited by the guide groove, which effectively solves the problem of uneven material size after slitting caused by irregular swaying of the slitting knife when it moves along the height of the frame;
[0017] 3. By limiting the swing path of the first pendulum along the first base through the guide member, the swing path of the second pendulum along the first pendulum is indirectly limited, thereby improving the stability of the second pendulum swinging along the first pendulum and reducing the gap when the second pendulum swings along the first pendulum.

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0023] This application discloses a clay extrusion and slitting apparatus. (Refer to...) Figure 1 and Figure 2 A clay extrusion slitting device includes a frame 1 and a conveyor belt 2 rotatably supported on the frame 1. One end of the conveyor belt 2 is connected to a clay extruder, and a slitting mechanism 3 is provided at the end of the conveyor belt 2 away from the clay extruder. The slitting mechanism 3 includes a drive assembly 31, a transmission assembly 32, and a slitting blade 33. The transmission assembly 32 includes a first base 321, a first swing arm 322, and a second swing arm 323. The first base 321 is disposed on the frame 1. The first swing arm 322 is rotatably connected to the first base 321. The second swing arm 323 is rotatably connected to the first swing arm 322 and is movably connected to the slitting blade 33. The drive assembly 31 is connected to the slitting blade 33. When the drive assembly 31 drives the slitting blade 33 to slitting the raw material located on the conveyor belt 2, the slitting blade 33 synchronously drives the second swing arm 323 to swing along the first swing arm 322.
[0024] First, it should be noted that the "conveyor belt 2 that rotates and is supported on the frame 1" can be driven by a drive motor to transport raw materials. The specific composition and working principle of the conveyor belt 2 are conventional conveying components, and will not be elaborated here.
[0025] Specifically, the first base 321 is mounted on the frame 1 at the end away from the clay extruder. The drive assembly 31 includes a servo motor 311, a rotary wheel 312, and a swing arm 313. The servo motor 311 is mounted on the frame 1. The rotary wheel 312 is coaxially fixed with the output shaft of the servo motor 311. A rotating shaft 3121 is provided on the surface of the rotary wheel 312 that is off-center. One end of the swing arm 313 along the length direction is rotatably connected to the rotating shaft 3121, and the other end of the swing arm 313 along the length direction is rotatably connected to the slitting blade 33.
[0026] Among them, the frame 1 is mounted on one side of the first base 321 with a support frame 9. The servo motor 311 is mounted on the support frame 9 in the horizontal direction. Since the rotating shaft 3121 is located on the surface of the rotating wheel 312 that is off-center from its center, and the swing arm 313 is rotatably connected to the rotating shaft 3121, when the output shaft of the servo motor 311 drives the rotating wheel 312 to rotate, the swing arm 313 swings along the rotating wheel 312 with the rotating shaft 3121 as the base point.
[0027] Furthermore, a first pivot shaft 10 is provided through the first pivot rod 322 along its length direction. The first pivot shaft 10 is fixedly connected to the first pivot rod 322, and both ends of the first pivot shaft 10 along its length direction are rotatably connected to the first base 321.
[0028] Furthermore, the second swing arm 323 is inserted through the second rotating shaft 11 along the length direction, and the second rotating shaft 11 is fixedly connected to the second swing arm 323. The two ends of the second rotating shaft 11 along the length direction are rotatably connected to the second swing arm 323.
[0029] Thus, the first pendulum 322 can swing along the first base 321 via the first rotating shaft 10, and the second pendulum 323 can swing along the first pendulum 322 via the second rotating shaft 11.
[0030] Furthermore, a guide plate 4 is provided on the second swing arm 323, and a guide groove 41 is provided on the guide plate 4 along the height direction. The slitting blade 33 slides in conjunction with the guide groove 41. The guide plate 4 is fixed to the second swing arm 323 along the height direction of the frame 1 by bolts. Because the guide plate 4 has a guide groove 41, the movement path of the slitting blade 33 along the height direction of the frame 1 is limited by the guide groove 41, which effectively solves the problem of uneven material size after slitting caused by irregular swaying of the slitting blade 33 when moving along the height direction of the frame 1.
[0031] Meanwhile, a guide member 5 is provided on the first base 321. The guide member 5 has an arc-shaped waist-shaped groove 51, and there are two guide members 5. The two guide members 5 are located at both ends of the width direction of the first base 321. Since the two guide members 5 are connected to the first swing rod 322 and the second swing rod 323 in the same way, the following will describe in detail the cooperation between one of the guide members 5 and the first swing rod 322 and the second swing rod 323. The end of the first swing rod 322 away from the first base 321 slides and engages with the arc-shaped waist-shaped groove 51. The two ends of the second rotating shaft 11 along the length direction are movably inserted into the arc-shaped waist groove 51. When the first swing rod 322 swings along the first base 321 through the first rotating shaft 10, the second swing rod 323 is rotatably connected to the first swing rod 322 through the second rotating shaft 11, and the two ends of the second rotating shaft 11 along the length direction are located in the arc-shaped waist groove 51. When the second swing rod 323 moves, the guide member 5 limits the swing path of the first swing rod 322 along the first base 321, thereby indirectly achieving the purpose of limiting the swing path of the second swing rod 323 along the first swing rod 322, improving the stability of the second swing rod 323 swinging along the first swing rod 322, and reducing the gap when the second swing rod 323 swings along the first swing rod 322.
[0032] Reference Figure 1 and Figure 3 The first swing arm 322 has a relief groove 3221, and the swing arm 313 is located in the relief groove 3221. The relief groove 3221 is located at the midpoint of the first swing arm 322 along its length direction, and the relief groove 3221 is formed by a recess in the thickness direction of the first swing arm 322. When the swing arm 313 moves, the relief groove 3221 provides relief, ensuring that the swing arm 313 never comes into contact with the first swing arm 322. This avoids mechanical interference to the movement of the swing arm 313 due to contact with the first swing arm 322, which would prevent the swing arm 313 from swinging smoothly.
[0033] Reference Figure 2 Two sets of preliminary shaping components 6 are provided on the frame 1 located below the first base 321. The two sets of preliminary shaping components 6 are symmetrically arranged about the center line of the conveyor belt 2 along the width direction. The preliminary shaping component 6 includes a drive cylinder 61 and a shaping mold 62. The shaping mold 62 is fixedly connected to the piston rod of the drive cylinder 61. When the slitting blade 33 cuts the raw material, the piston rod of the drive cylinder 61 drives the shaping mold 62 to simultaneously shape the raw material located between the slitting blade 33 and the clay extruder.
[0034] The purpose is that when the raw material extruded by the clay extruder falls onto the conveyor belt 2, as the conveyor belt 2 travels a longer distance, the raw material will become soft due to its own characteristics and mechanical vibration, which is not conducive to the radial movement of subsequent processing steps. Therefore, when the conveyor belt 2 transports the raw material to the vicinity of the slitting knife 33, the shaping mold 62 is driven by the drive cylinder 61 to shape the raw material, so as to reduce the deformation of the raw material. Then, the shaped raw material reaches the slitting knife 33 and can be slit by the slitting knife 33.
[0035] Reference Figure 1 and Figure 2 The frame 1 is provided with a thickness adjustment component 7, which includes an adjustment block 71, a limiting roller 72 and a handle bolt 73. The limiting roller 72 is rotatably connected to the adjustment block 71. The frame 1 is provided with a limiting groove 8 through the thickness direction. The adjustment block 71 is inserted into the limiting groove 8. The handle bolt 73 is threaded through the side wall of the frame 1 and extends into the limiting groove 8. When the adjustment block 71 is located in the limiting groove 8, the handle bolt 73 abuts against the adjustment block 71.
[0036] Specifically, the thickness adjustment component 7 is located on the frame 1 on the side of the slitting blade 33 away from the drive cylinder 61. Its purpose is that the height of the raw material after being slit by the slitting blade 33 may not meet the design requirements, which will interfere with subsequent processing steps. Therefore, by adjusting the distance between the limiting roller 72 and the conveyor belt 2, the height of the slit raw material can be adjusted. When the raw material reaches below the limiting roller 72, the height of the slit raw material is adjusted by the limiting roller 72 to make the height of the raw material meet the design requirements.
[0037] Therefore, when it is necessary to adjust the distance between the limit roller 72 and the conveyor belt 2, the handle bolt 73 can be loosened to adjust the adjusting block 71 along the height position of the frame 1. After the adjustment of the adjusting block 71 along the height distance of the frame 1 is completed, the handle bolt 73 can be tightened again. The operation is simple.
[0038] The implementation principle of the clay extrusion slitting device in this application embodiment is as follows: When it is necessary to slit the raw material located on the conveyor belt 2, the drive assembly 31 drives the slitting blade 33 to move. Because the second swing arm 323 is movably connected to the slitting blade 33, at the same time as the drive assembly 31 drives the slitting blade 33 to move, the second swing arm 323 will swing along the first swing arm 322 due to the force applied by the slitting blade 33. Since the first swing arm 322 is movably connected to the first base 321, the first swing arm 322 will also swing along the second swing arm 323. Thus, when the slitting blade 33... After the raw material on the conveyor belt 2 is cut and moves away from the surface of the conveyor belt 2, the second swing arm 323, in conjunction with the first swing arm 322, drives the slitting blade 33 to swing horizontally along the conveyor belt 2. At this time, because the conveyor belt 2 is in motion, the slitting blade 33 increases the distance between two adjacent raw materials through the blocking effect of the slitting blade 33, so as to force the two adjacent raw materials to separate. The separation operation and the cutting operation are synchronized, resulting in high cutting efficiency. This plays a positive guiding role in improving the efficiency of cutting the raw material after it is extruded from the clay extruder.
[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
