Description

Technical Field

[0001] The present application relates to the field of solar screen technology, and in particular to a device for cutting screen cloth to length. Background Art

[0002] A solar screen is a template used in the solar cell printing process. It consists of a screen frame and a mesh. The mesh is made from a wound mesh roll. When making a solar screen, the mesh is pulled from the roll, flattened, measured, and cut to size before being installed in the screen frame. The more precise the mesh cutting length, the better.

[0003] Currently, the mesh is cut by pulling out the mesh and placing it on a platform. The mesh is then flattened with a rod to make it flat, and then the length is measured for cutting.

[0004] Regarding the above-mentioned related technologies, the inventor believes that it is rather troublesome to flatten the mesh, requiring personnel to repeatedly take and place the rods, and the pressure of the rods on the mesh is insufficient, which easily causes the mesh to shift during cutting, and needs to be improved. Summary of the Invention

[0005] The present application provides a mesh fixed-length cutting device, which uses automated equipment to flatten and press the mesh to fix it. The mesh is not easily shifted during cutting, and the mesh is ensured to be flat through a pad, reducing manual labor.

[0006] This application provides a mesh cutting-to-length device, which adopts the following technical solutions: A mesh cloth fixed-length cutting equipment, characterized in that: it includes a frame and a pad, the frame is slidingly provided with a slide seat 1 and a slide seat 2, the slide seat 1 is driven to slide by a servo motor 1, the side wall of the slide seat 1 is provided with a limiting groove 1 for the end of the mesh cloth to enter, a plurality of cylinders 1 are fixed on the slide seat 1, the piston rod end of the cylinder 1 is fixed with a pressure block 1, and the pressure block 1 is located in the limiting groove 1; the side wall of the slide seat 2 is penetrated by a limiting groove 2 for the mesh cloth to pass through, a plurality of cylinders 2 are fixed on the slide seat 2, the piston rod end of the cylinder 2 is fixed with a pressure block 2, and the pressure block 2 is located in the limiting groove 2; the pad is slidably connected to the frame in the vertical direction, and the frame is fixed with a cylinder 3, and the cylinder 3 is used to drive the pad to rise and fall.

[0007] By adopting the above technical solution, the mesh is supported and flattened by a liftable pad, and the lowering of the pad does not affect the movement of slide 1. The end of the mesh is pressed by cylinder 1 and pressure block 1, and the mesh is stretched by servo motor 1. The other end of the mesh to be cut is pressed by cylinder 2 and pressure block 2, so that the mesh is reliably flattened and does not move during cutting, achieving high cutting stability.

[0008] Optionally, the end of the slide 2 close to the slide 1 is rotatably connected to a pressing plate, and a cutting groove is provided on the pressing plate.

[0009] By adopting the above technical solution, the pressing plate rotates downward and presses on the mesh, pressing the mesh by weight, and the cutting groove enables the tool to move along a straight line during cutting, thereby improving the straightness of cutting.

[0010] Optionally, the frame is fixed with a guide rod and rotatably connected to a screw rod 1. The slide 1 and slide 2 are both slidably connected to the guide rod. The slide 1 is threadedly connected to the screw rod 1. The screw rod 1 is driven to rotate by a servo motor 1. The guide rod is provided with a scale along its length.

[0011] By adopting the above technical solution, when the servo motor 1 is running, the screw rod 1 drives the rotation, and the screw rod 1 drives the slide 1 to slide through the threaded connection; the sliding stability of the slide 1 and the slide 2 is improved by the guide rod, and the length of the mesh to be cut is determined by the scale.

[0012] Optionally, after the pad is raised, the slide seat 1 is located outside the side wall of the pad, and the inner bottom wall of the limiting groove 1 is flush with the top surface of the pad.

[0013] By adopting the above technical solution, after the slide pulls the end of the mesh to the outside of the pad, the pad rises, making the mesh to be cut completely flat without height difference and wrinkles, making the length measurement more accurate.

[0014] Optionally, a pressure sensor is fixed to the side wall of the slide 1 facing the slide 2, the pressure sensor is electrically connected to the controller, and the pressure sensor is used to control the servo motor 1 to stop rotating.

[0015] By adopting the above technical solution, when Slide 1 moves toward Slide 2 and is about to contact it, Slide 2 presses the pressure sensor, thereby controlling servo motor 1 to stop working, preventing Slide 1 and Slide 2 from causing a hard collision. Slide 1 can also automatically stop moving, making it easier for the subsequent cylinder 1 and clamping block 1 to clamp the end of the mesh.

[0016] Optionally, the frame is equipped with a roller for the mesh roll to be sleeved, and the position where the mesh is led out of the mesh roll is located at the bottom of the mesh roll.

[0017] By adopting the above technical solution, the rollers are placed on the frame at both ends through a bracketed arrangement, facilitating the installation of the mesh roll. Since the mesh exits the roll at the bottom, the mesh tends to be concave in the middle due to its own elasticity after being unrolled. At this time, the pad rises to support the mesh, pushing the concave area upward and flattening the mesh, making it easier to fully flatten the mesh.

[0018] Optionally, the second slide seat is threadedly connected with a locking bolt, and the end of the locking bolt abuts against the guide rod.

[0019] By adopting the above technical solution, the locking bolt is rotated to make its end abut against the outer wall of the guide rod, thereby locking the position of the slide seat 2.

[0020] Optionally, the frame is installed with a servo motor 2 and a screw rod 2 driven to rotate by the servo motor 2, and the screw rod 2 passes through the slide 2 and is threadedly connected to the slide 2.

[0021] By adopting the above technical solution, slide two is moved electrically, and the rotation angle of the servo motor can be precisely controlled. By inputting the cutting length into the controller, the controller outputs a signal to servo motor two, which can directly move slide two into position without the need for measurement according to the scale, further reducing the amount of manual labor.

[0022] Optionally, a linear module is fixed on the slide seat 2, a cylinder 4 is fixed on the moving end of the linear module, a connecting block is fixed on the piston rod end of the cylinder 4, and a cutting knife is fixed on the bottom surface of the connecting block.

[0023] By adopting the above technical solution, cutting is carried out automatically, further reducing the amount of manual labor. After the cylinder is extended, the cutting knife moves downward, and then the linear module works to move the cutting knife horizontally, thus completing the automatic cutting of the mesh.

[0024] Optionally, a torsion spring is provided between the slide seat 2 and the pressure plate, and the elastic force of the torsion spring drives the pressure plate to rotate upward; the connecting block is slidably connected to the pressure block 3 through the sliding rod, and the pressure block 3 is used to press the pressure plate downward, and a spring is provided between the pressure block 3 and the connecting block.

[0025] By adopting this technical solution, when the pressure plate is not pressed down, the torsion spring's force causes it to rotate upward, tilting it away from the mesh. This prevents the pressure plate from dragging the mesh when slide two moves. Before the cutting blade moves down into position, pressure block three first contacts the pressure plate, which then compresses the spring. Pressure block three maintains downward pressure on the pressure plate, overcoming the torsion spring's force and keeping the pressure plate flat against the mesh, allowing for a stable cutting process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The mesh to be cut is completely flat, without height differences and wrinkles, making the length measurement more accurate; 2. The two ends of the mesh to be cut are pressed by pressing block 1 and pressing block 2 respectively, and the pressing plate ensures that the cutting position is pressed tightly; because the cutting position is close to pressing block 2, the mesh does not move during cutting, and the cutting stability is high; 3. The mesh pulling out work can be done automatically, reducing the manual labor. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] Reference Figure 1 A mesh fixed-length cutting device includes a frame 1 and a pad 2. The frame 1 is slidingly provided with a slide 3 and a slide 2 4. The frame 1 is installed with a roller 11 for the mesh roll to be sleeved. The two ends of the roller 11 are placed on the frame 1 by a frame arrangement. The position where the mesh 10 is led out of the mesh roll is located at the bottom of the mesh roll.

[0032] Reference Figure 2 and Figure 3 The side wall of the slide 3 is provided with a limiting groove 31 for the end of the mesh cloth 10 to enter, and a plurality of cylinders 32 are fixed on the slide 3, and a pressure block 33 is fixed at the piston rod end of the cylinder 32, and the pressure block 33 is located in the limiting groove 31; the side wall of the slide 2 4 is penetrated by a limiting groove 2 41 for the mesh cloth 10 to pass through, and a plurality of cylinders 2 42 are fixed on the slide 2 4, and a pressure block 2 43 is fixed at the piston rod end of the cylinder 2 42, and the pressure block 2 43 is located in the limiting groove 2 41.

[0033] A pressure plate 44 is rotatably connected to the end of slide 2 (4) near slide 1 (3). This plate is provided with a cutting slot 45. The top notch of this slot is flared to facilitate entry of a cutting tool. The narrower notch at the bottom of the slot limits the cutting tool, ensuring that the tool moves in a straight line during cutting, improving the straightness of the cut. The pressure plate 44 rotates downward and presses against the mesh 10, tightening it with its weight. After rotating upward past 90 degrees, the pressure plate 44 rests obliquely against slide 2 (4). At this point, the pressure plate 44 is clear of the mesh 10, facilitating its removal and removal.

[0034] The pad 2 is slidably connected to the frame 1 in the vertical direction. The frame 1 is fixed with a cylinder three 21. The telescopic end of the cylinder three 21 is fixed to the bottom surface of the pad 2. There are multiple cylinders three 21 along the circumference of the pad 2. The cylinder three 21 is used to drive the pad 2 to rise and fall.

[0035] Servo motor 12 is fixed to frame 1, which drives slide 3. A guide rod 13 is fixed to frame 1, rotatably connected to screw rod 14. Slide 3 and slide 2 4 are both slidably connected to guide rod 13. Slide 3 is threadedly connected to screw rod 14, which is rotated by servo motor 12. When servo motor 12 is in operation, it drives slide 3 to slide closer to or farther from slide 2 4. Scale 15 is provided along the length of guide rod 13, which is used to determine the desired length of mesh 10 to be cut.

[0036] A pressure sensor 16 is fixed to the side wall of Slide 1 (3) facing Slide 2 (4). This pressure sensor 16 is electrically connected to a controller and is used to control the servo motor 12 to stop. When Slide 1 (3) moves toward Slide 2 (4) and is about to make contact, Slide 2 (4) presses against pressure sensor 16, thereby stopping servo motor 12.

[0037] The slide 2 4 is threadedly connected with a locking bolt 46, and the end of the locking bolt 46 abuts against the guide rod 13. After the slide 2 4 is moved into position, the locking bolt 46 is rotated so that its end abuts against the outer wall of the guide rod 13, thereby locking the position of the slide 2 4.

[0038] After the pad 2 is raised, the slide 1 3 is located outside the side wall of the pad 2, and the inner bottom wall of the limit groove 1 31 is flush with the top surface of the pad 2. The bottom wall of the limit groove 2 41 near the edge of the slide 1 3 is a circular surface, which prevents the mesh 10 from being creased at this position.

[0039] In this embodiment, slide 2 (4) is manually slidable, allowing precise control of its position and measurement of the cutting length using scale 15. Once slide 2 (4) is in position, locking bolt 46 is rotated until its end abuts against the outer wall of guide rod 13, thereby locking slide 2 (4). Pressing plate 44 is then rotated downward, pressing against mesh 10. A knife or cutting tool is then used to cut mesh 10 through cutting slot 45. Once cutting is complete, pressing plate 44 is flipped upward, and cylinder 1 (32) releases mesh 10, allowing the cut-to-length mesh 10 to be removed.

[0040] The working principle of the mesh cloth fixed-length cutting equipment of this embodiment is as follows: a person adjusts the position of the cutting groove 45 relative to the mesh cloth 10 by sliding the slide 2 4, and presses the pressing plate 44 against the mesh cloth 10. Since the slide 1 3 is located outside the side wall of the backing plate 2, the inner bottom wall of the limiting groove 1 31 is flush with the top surface of the backing plate 2. The mesh cloth 10 to be cut is completely flat, without height differences or wrinkles, making the length measurement more accurate. The two ends of the mesh cloth 10 to be cut are respectively pressed by the pressing block 1 33 and the pressing block 2 43, and the pressing plate 44 ensures that the cutting position is pressed tightly. Since the cutting position is close to the pressing block 2 43, the mesh cloth 10 does not move during cutting, and the cutting stability is high.

[0041] The operator uses a knife or cutting tool to cut the mesh 10 through the cutting groove 45. After cutting, the cylinder 1 32 drives the pressing block 1 33 to move upward, and the operator flips up the pressing plate 44 to remove the cut mesh 10. At this time, the end of the mesh 10 remaining on the backing plate 2 is located outside the slide 2 4.

[0042] Reference Figure 4 Then, the reset process starts: pad 2 moves downward, servo motor 12 operates to move slide 1 3 toward slide 2 4. When slide 1 3 reaches its limit position, pressure sensor 16 stops it. During this process, pressure plate 44 enters limit slot 1 31, and then pressure block 1 33 moves downward to clamp the end of mesh 10. Pressure block 2 43 moves upward to release mesh 10. Slide 1 3 then moves away from slide 2 4, thereby pulling mesh 10 out and spreading it again. Pad 2 rises, and the next cutting can begin. With this device, the mesh 10 pulling operation can be performed automatically, reducing manual labor.

[0043] Example 2:

[0044] A mesh fabric cutting-to-length device, the difference between the second embodiment and the first embodiment is that: Reference Figure 5 and Figure 6In this embodiment, slide 2 (4) is electrically driven. Specifically, frame 1 is equipped with servo motor 2 (17) and screw rod 2 (18), which is driven by servo motor 2 (17). Screw rod 2 (18) passes through slide 2 (4) and is threadedly connected to slide 2 (4). Screw rod 2 (18) is parallel to screw rod 1 (14). Servomotor 2 (17) is electrically connected to a controller. The servomotor's rotation angle can be precisely controlled. By inputting the cutting length into the controller, the controller outputs a signal to servomotor 2 (17), directly moving slide 2 (4) into position. Without measuring with scale 15, the cutting groove 45 on the pressure plate 44 can be aligned with the desired cutting position.

[0045] Furthermore, this embodiment utilizes an automatic cutting method. Specifically, a linear module 5 is fixed to the second slide 4. A cylinder 4 is fixed to the movable end of the linear module 5. A connecting block 52 is fixed to the piston rod end of the cylinder 4, and a cutting blade 53 is fixed to the bottom surface of the connecting block 52. The cutting blade 53 is located directly above the cutting groove 45. When the cylinder is extended, the cutting blade 53 is inserted into the cutting groove 45. The linear module 5 then operates, moving the cutting blade 53 horizontally, thereby completing the automatic cutting of the mesh 10.

[0046] A torsion spring 47 is provided between the second slide 4 and the pressure plate 44. The torsion spring 47 is mounted at the pivoting connection between the second slide 4 and the pressure plate 44. The elastic force of the torsion spring 47 drives the pressure plate 44 to rotate upward. When the pressure plate 44 is not pressed downward, the pressure plate 44 rotates upward and is tilted. The pressure plate 44 does not contact the mesh 10, preventing the pressure plate 44 from dragging the mesh 10 when the second slide 4 moves.

[0047] Connecting block 52 is slidably connected to pressure block 3 54 via a slide bar. Pressure block 3 54 is located below connecting block 52, and the cutting blade 53 passes through pressure block 3 54. Pressure block 3 54 is used to press down the pressure plate 44. Made of polytetrafluoroethylene, pressure block 3 54 reduces sliding friction and wear. A spring 55 is interposed between pressure block 3 54 and connecting block 52. Before the cutting blade 53 moves downward into position, pressure block 3 54 first contacts the pressure plate 44. This compresses the spring 55, maintaining downward pressure on the pressure plate 44, overcoming the elastic force of torsion spring 47 and ensuring that the pressure plate 44 lies flat against the mesh 10, allowing for a stable cutting process.

[0048] In summary, through this embodiment, the automatic cutting of the mesh 10 is completed, which improves automation and further saves manpower.

[0049] The above are all 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.
