Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery edge cutting and punching technology, and more specifically, to an edge cutting and punching device. Background Technology

[0002] Agricultural machinery conveyor belts require edge trimming and perforation. Edge trimming is not only to match the width of the conveyor belt to the equipment, but also to prevent uneven edges from easily entangled with straw, weeds, or plastic film. Perforation helps with drainage and mud removal, reduces the load on the agricultural machinery, and prevents crops from accumulating and corroding in humid environments. In the current technology, since there is no dedicated production equipment for agricultural machinery conveyor belts, edge trimming and perforation are carried out separately. This not only reduces the processing efficiency of this type of conveyor belt, but also requires two large pieces of equipment with high purchase costs. Therefore, an edge trimming and perforation device is proposed. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 6This utility model discloses a cutting and punching device, including a workbench 1. The workbench 1 can be used to move and process the conveyor belt. The workbench 1 is arranged in sequence along the length direction as a cutting area 4, a aligning area 2, and a punching area 3. The cutting area 4 includes a cutting component 41. The workbench 1 has a working opening 11 on its surface. The cutting component 41 passes through the working opening 11 and acts on the conveyor belt on the workbench 1 to cut both sides of the conveyor belt. The aligning area 2 has an aligning channel 24 and a fixed aligning plate 21. The punching area 3 has an initial position. The fixed aligning plate 21 is aligned with the initial position in the front-back direction. The punching area 3 has a punching component 31. In the initial state, the punching component 31 is located above the initial position. This invention integrates two consecutive steps by setting up a trimming area 4 and a punching area 3 on a workbench 1, and setting a matching area 2 between the trimming area 4 and the punching area 3. The matching area 2 is set in the middle of the two steps, and the trimmed conveyor belt is aligned with the initial position of the punching area 3, so as to achieve continuous processing of the two steps. This invention can be specifically used for trimming and punching processing of agricultural machinery conveyor belts, which improves the production efficiency of agricultural machinery conveyor belts. Moreover, through simplified design, the volume is reduced and it is easier to use.

[0028] The punching area 3 includes a first drive motor 33 and a moving slide 32. The punching component 31 includes a linked cylinder 312 and a rotary motor 311. The output end of the rotary motor 311 is fixed to the cylinder 312, and the output end of the cylinder 312 is detachably connected to the punching drill bit 313. Both the first drive motor 33 and the rotary motor 311 are servo motors. The moving slide 32 includes a first slider 321, a first threaded rod, a limit sensor, a grating ruler, a pressure sensor, a thickness sensor, and a sensing sensor. A first movable block is rotatably set inside the first slider 321. The first movable block is threadedly connected to the first threaded rod, so that the first slider 321 slides linearly along the first threaded rod. The first slider 321 is connected to the punching component 31, and the first threaded rod is connected to the output end of the first drive motor 33. The limit sensor is used for position initialization, the grating ruler is used for real-time feedback of the actual position, the thickness sensor is used to detect whether the thickness of the conveyor belt is greater than 4mm, the pressure sensor is used to verify the punching pressure meets the standard deviation, and the sensing sensor is used to sense the conveyor belt entering the punching area. Data signals from the sensing sensors, limit sensors, thickness sensors, and pressure sensors are all sent to the PLC controller. The first drive motor 33 is electrically connected to the PLC controller. The gap between the transverse holes is programmed into the PLC controller according to requirements. The PLC controller outputs commands, such as a relative movement of 6.000mm (MOV REL 6.000mm). When the position reaches the 5.998-6.002mm range and the thickness is greater than 4mm, an output signal is sent to start cylinder 312 and rotary motor 311. When the position reaches the 5.998-6.002mm range and the thickness is less than or equal to 4mm, cylinder 312 is started. The gap between the longitudinal holes is controlled by a moving roller in the punching area. The moving roller can also be programmed to be controlled by the PLC controller. After the punching part has punched a row of holes, the PLC controller outputs a command, such as rotating one revolution. After the moving roller drives the conveyor belt to move, the punching part returns to the initial position to punch a new row of holes.

[0029] The cutting area 4 also includes a pressing component 45, which is disposed above the cutting component 41. The pressing component 45 includes a first connecting block 451 and a pressing block 452 (e.g., Figure 4 As shown, the first connecting block 451 has a strip-shaped hole 4511 in the height direction, and the lower pressing block 452 has a first screw hole 4521. The first screw hole 4521 is aligned with any position of the strip-shaped hole 4511. A first tightening bolt is provided in the strip-shaped hole 4511 and the first screw hole 4521, and the first tightening bolt fixes the first connecting block 451 and the lower pressing block 452. The first tightening bolt limits the connection position in the strip-shaped hole 4511 to adjust the height of the lower pressing block 452. When the bottom of the lower pressing block 452 abuts against the upper surface of the conveyor belt and the lower surface of the conveyor belt is in contact with the table surface of the workbench 1, the cutting assembly 41 can better apply cutting force to the conveyor belt.

[0030] This utility model also includes a guide rod, the direction of which is parallel to the width direction of the conveyor belt. The first connecting block 451 is provided with a connecting groove 4513, and the guide rod is provided in the connecting groove 4513 so that the first connecting block 451 moves along the guide rod. The connecting groove 4513 is provided with a second screw hole 4512, and a second tightening bolt is provided in the second screw hole 4512. The body of the guide rod is provided with an abutment plane 461. The end of the second tightening bolt passes through the second screw hole 4512 and presses against the abutment plane 461, so that the first connecting block 451 is fixedly limited to any position of the guide rod, which makes it convenient to adjust the position of the first connecting block 451 according to the position of the cut piece.

[0031] The workbench 1 is equipped with a chute 12, which is parallel to the perforated area 3. The edge-aligning area 2 includes a movable edge-aligning plate 25. The movable edge-aligning plate 21 is equipped with a pulley 23, which is movably disposed within the chute 12. This allows the distance between the fixed edge-aligning plate 21 and the movable edge-aligning plate 25, i.e., the width of the edge-aligning channel 24, to be adjusted according to the width of the conveyor belt. A limiting bolt 22 is provided within the chute 12. The limiting bolt 22 is threadedly connected to the edge-aligning plate 21. The limiting bolt 22 has an anti-slip bottom 221 made of rubber. When the anti-slip bottom 221 abuts against the bottom of the chute 12, the pulley 23 stops in time. In specific operation, the fixed edge-aligning plate 21 is aligned with the initial position of the perforated area 3. One side of the trimmed conveyor belt attempts to adhere to the fixed edge-aligning plate 21. The movable edge-aligning plate 25 moves on the chute 12 to adhere to the other side of the conveyor belt, thus aligning the conveyor belt with the perforated area 3. One side of the conveyor belt is aligned with the initial position of the perforated area 3.

[0032] Cutting assembly 41 includes a circular cutter 411 and a rotary motor 412 (e.g., Figure 5 As shown), the base assembly 42 includes a base plate 422 and a connecting plate 421. The connecting plate 421 is provided with a bearing seat. A fixed shaft is provided on the circular cutter 411. The fixed shaft is movably disposed in the bearing seat. The output end of the rotary motor 412 is provided with a first transmission wheel 4121. A second transmission wheel 4111 is provided on the fixed shaft. A transmission belt is sleeved on the first transmission wheel 4121 and the second transmission wheel 4111, so that the circular cutter 411 rotates to cut. Rotational cutting can improve the sharpness of the cut, avoid material stretching and deformation, and produce a smooth cut.

[0033] The base plate 422 has an adjusting bolt 43 in the height direction, and the connecting plate 421 has a second connecting block 47 with bolt holes. The adjusting bolt 43 is inserted into the bolt holes, and the second connecting block 47 moves along the adjusting bolt 43 to a suitable position. Then, the adjusting bolt 43 is engaged with the nut 44, so that the second connecting block 47 is fixed at any position of the adjusting bolt 43. Thus, the distance from the highest point of the circular cutter 411 to the working opening 11 is adjusted according to the thickness of the conveyor belt. The distance from the highest point of the circular cutter 411 to the working opening 11 is slightly larger than the thickness of the conveyor belt, which is more conducive to cutting.

[0034] This utility model also includes a linear module 49, which includes a guide rail, two second sliders, two second threaded rods, and two second drive motors. The second sliders are rotatably mounted with second movable blocks, which are threadedly connected to the second threaded rods, allowing the second sliders to reciprocate along the second threaded rods. The second sliders, base assembly 42, second sliders, and second threaded rods are connected in a one-to-one correspondence with the drive motors. Both second sliders are movably mounted on the guide rail at their bottoms. The operator inputs a command for the cutting edge width through the human-machine interface. This command is sent to the controller. Upon receiving the command from the controller, the second drive motors start, and after the second sliders move along the second threaded rods to the commanded position, the rotary motor 412 automatically starts.

[0035] A guide roller 48 is provided between the cutting components 41. The guide roller 48 is an electric roller that moves the conveyor belt toward the opposite side area 2.

[0036] To clarify, the conveyor belt is divided into a trimmed section and a section to be trimmed, depending on whether it is trimmed. During operation, the operator pushes the section to be trimmed into the trimming zone 4. The bottom surface of the pressing block 452 of the pressing assembly 45 in the trimming zone 4 adheres to the upper surface of the section to be trimmed, ensuring that the lower surface of the section to be trimmed adheres to the workbench 1. At this time, the cutting assembly 41 acts on the section to be trimmed, trimming both sides of the section to be trimmed to create flat edges. The guide roller 48 then moves the trimmed conveyor belt (i.e., the trimmed section) from the trimming zone 4 to the opposite zone 2. The operator gradually aligns the sides of the trimmed section with and fixes the trimming plate 21. The cutting plate 25 is adjusted to fit the other side of the cutting section. At this time, the cutting section is aligned with the punching area 3, and one side of the cutting section is aligned with the initial position of the punching area 3. It should be noted that if the position of the cutting section moves too much when aligning the edges, the position of the cutting section will also shift, which will affect the cutting. Therefore, when adjusting the position of the cutting component 41, the position of the circular cutter 411 needs to be adjusted to be aligned with the fixed edge plate 21, so that one side of the cutting section is close to the fixed edge plate 25 before entering the edge channel 24, and slides out with the side of the cutting section against the fixed edge plate 21 after entering the edge channel 24. When the punching area 3 detects that the cutting section has entered the punching area 3, it starts the punching component 31, the first drive motor 33 and the moving roller. The punching drill bit 313 of the punching component 31 punches an array of holes along the width and length of the cutting section, thereby completing the two consecutive steps of cutting and punching the conveyor belt.

[0037] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
