Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, in particular to a rubber plate flat cutting device. Background Art

[0002] Plastic sheets are commonly used in industrial production, such as polyurethane sheets (PU sheets). During the production process, plastic sheets are formed into a large sheet of a certain thickness, and then cut into specific sizes.

[0003] The Chinese patent document with authorization announcement number CN214604614U discloses a silicone plate cutting device, comprising a frame, a transverse motion mechanism, a longitudinal motion mechanism and a cutting mechanism; a working platform is installed on the upper end of the frame, and the transverse motion mechanism comprises a slide rail, a sliding frame, a first lead screw and a motor, and slide rails are respectively installed on both sides of the frame, one end of the first lead screw is rotatably matched with one end of the frame, and the other end passes through the other end of the frame and is connected to the motor shaft of the motor through a coupling; both sides of the frame are slidably matched with the sliding frame, and a slide groove is provided at the lower end of the sliding frame, and the slide rail is placed in the slide groove of the sliding frame. One of the slides is fixedly connected to a lead screw nut, which in turn cooperates with the first lead screw. The longitudinal motion mechanism includes a guide frame, a second lead screw, and a slider. Both ends of the guide frame are fixedly connected to the slide frame. The guide frame is provided with a rectangular guide hole. One end of the second lead screw rotates with one end wall of the guide frame's rectangular guide hole, while the other end passes through the other end wall of the guide frame's rectangular guide hole and is connected to the motor shaft of the motor via a coupling. The slider is placed in the guide frame's rectangular guide hole and is provided with a threaded through hole. The second lead screw cooperates with the slider's threaded hole. The slider is connected to the cutting mechanism. The cutting mechanism is driven by the transverse and longitudinal motion mechanisms, and the blade of the cutting mechanism cuts the silicone sheet without manual cutting, greatly reducing the labor intensity of the staff.

[0004] In the technical solution of the aforementioned patent document, after the silicone sheet is placed on a workbench, a first screw drives the cutter to move longitudinally, while a second screw drives the cutter to move transversely, thereby achieving the silicone cutting process. However, when the silicone sheet is placed on the workbench, the force exerted by the cutter during the cutting process can cause the silicone sheet to loosen. This is particularly true when cutting the last section of the silicone sheet, as the overall weight of the silicone sheet decreases, reducing adhesion and thus causing the silicone sheet to loosen.

[0029] Reference Figure 1 and Figure 2 , the frame 100 is provided with a support surface 101, and the support surface 101 is used to support the rubber sheet to be cut, so that the rubber sheet to be cut can be laid flat on the support surface 101. The first translation mechanism 200 is provided on the frame 100. The movable frame 300 is provided on the first translation mechanism 200 and is located above the support surface 101. Among them, the first translation mechanism 200 can be an electric linear module provided on the frame 100. Specifically, the first translation 200 includes a guide rail 201, a mounting groove 202, a rack 203, a gear and a motor 204; the guide rail 201 and the mounting groove 202 are provided on the support surface 101, the movable frame 300 is connected to the guide rail 201, the rack 203 is provided on the inner side of the mounting groove 202, the motor 204 is provided on the movable frame 300, and the gear is provided on the main shaft of the motor 204 and meshes with the rack 203. Therefore, driven by the motor 204 , the gear is driven to rotate, and under the meshing action of the gear and the rack 203 , the movable frame 300 is pushed to translate along the guide rail 201 .

[0030] Reference Figure 3 and Figure 4The second translation mechanism 400 is arranged on the movable frame 300, and the movement directions of the first translation mechanism 200 and the second translation mechanism 400 are arranged perpendicular to each other. Among them, the second translation mechanism 400 can be an electric linear module. The cutting mechanism 500 includes a lifting drive member 510, a cutter 520, a pressure plate 530 and a downward pressure drive member 540. The lifting drive member 510 is arranged on the second translation mechanism 400, the cutter 520 is arranged at the bottom end of the lifting drive member 510, and the pressure plate 530 is arranged on the bottom side of the cutter 520. The pressure plate 530 is provided with a pressing portion to avoid the airflow of the cutter 520. The downward pressure drive member 540 is connected to both ends of the pressure plate 530. The downward pressure drive member 540 is arranged on the movable frame 300 and is used to drive the pressure plate 530 to press down to compress the rubber sheet to be cut. The rubber sheet can be placed on the support surface 101 and straightened. When cutting the rubber sheet, the first translation mechanism 200 drives the movable frame 300 to move, positioning the cutter 520 in the cutting position. The downward drive 540 drives the pressure plate 530 to press against the top side of the rubber sheet. The lift drive 510 then drives the cutter 520 downward, while the second translation mechanism 400 drives the cutter 520 to translate, cutting the rubber sheet. Because the pressure plate 530 holds the rubber sheet in place during the cutting process, loosening of the rubber sheet is prevented, ensuring smooth cutting.

[0031] Preferably, refer to Figure 6 The pressing plate 530 is provided with an air-avoiding groove 531, which forms two pressing parts on the pressing plate. The air-avoiding groove 531 avoids the cutter 520 from being in the air, and the pressing plate 530 presses the rubber sheets on both sides of the cutter 520 to increase the stability of the rubber sheets.

[0032] Preferably, refer to Figure 3 and Figure 4 The lifting drive 510 includes a mounting base 511, a cylinder 512, and a knife holder 513. The mounting base 511 is connected to the second translation mechanism 400, the cylinder 512 is mounted on the mounting base 511, the knife holder 513 is connected to the cylinder 512, and the cutter 520 is mounted at the bottom end of the knife holder 513. In this embodiment, the cylinder 512 drives the knife holder 513 downward, causing the cutter 520 to cut downward.

[0033] Preferably, refer to Figure 4 The back side of the knife seat 513 is provided with a guide groove 514, and the mounting seat 511 is provided with a limiting slider 515 extending into the guide groove 514. By cooperating with the limiting slider 515 and the guide groove 514, the stability of the knife seat 513 can be improved.

[0034] Preferably, refer to Figure 6The pressing plate 530 is further provided with a groove 532, which serves to provide a clearance for the blade holder 513. The clearance groove 531 is provided at the bottom of the groove 532. This embodiment prevents the cutter 520 from being too long when passing through the clearance groove 513, thereby ensuring the strength of the cutter 520. Furthermore, the thickness of the pressing plate 530 is maintained, preventing deformation when the pressing plate 530 is pressed against the rubber sheet.

[0035] Preferably, refer to Figure 5 and Figure 6 The downward pressing driving member 540 includes a downward pressing cylinder 541, a connecting plate 542, a guide shaft 543 and a compression spring 544. The downward pressing cylinder 541 is connected to the movable frame 300, and the connecting plate 542 is arranged at the bottom end of the downward pressing cylinder 541. Two guide shafts 543 connect the connecting plate 542 and the pressure plate 530, and the lower end of the guide shaft 543 is fixedly connected to the pressure plate 530, and the upper end slides through the connecting plate 542. The top end of the guide shaft is provided with a limit portion for limiting the position on the top side of the connecting plate; the compression spring is sleeved on the guide shaft and supported between the pressure plate 530 and the connecting plate 542. In this embodiment, when the downward pressing driving member 540 drives the pressure plate 530 to press down, the downward pressing cylinder 541 drives the connecting plate 542 to descend, so that the pressure plate 530 is pressed on the top side of the rubber plate, and the compression spring 544 is compressed. Under the action of the compression spring 544, it not only plays a buffering role, but also plays a role in maintaining pressure after being compressed.

[0036] Preferably, refer to Figure 1 and Figure 2 A backing plate 110 is also provided on the support surface 101. A plurality of cutting grooves 111 are provided on the backing plate 110 along the movement direction of the first translation mechanism 200. The cutting grooves 111 are used to avoid the cutter 520. In this embodiment, the rubber sheet to be cut can be laid flat on the backing plate 110. When cutting the rubber sheet, the cutter cuts the rubber sheet along the cutting grooves 111, thereby preventing the cutter 520 from contacting the backing plate 110 or the support surface 101, and providing good protection for the cutter 520 and the support surface 101. In addition, the backing plate 110 is made of multiple independent plates, so the spacing of the cutting grooves 111 can be adjusted according to actual needs.

[0037] Preferably, refer to Figure 1 and Figure 2 , there are also baffles 120 on both sides of the backing plate 110, and a plurality of pressing blocks 130 are provided on the baffles 120 for pressing the rubber sheet to be cut on the backing plate 110. The baffles 120 limit the position of the rubber sheet, and the pressing blocks 130 are used to press the rubber sheet against the backing plate 110 to increase the stability of the rubber sheet.

[0038] Preferably, refer to Figure 3A fixed cylinder 310 is further provided at one end of the movable frame 300. A rubber block 320 is provided at the bottom end of the fixed cylinder 310. The fixed cylinder 310 drives the rubber block 320 to press against the support surface 101. Specifically, in this embodiment, when the cutter 520 cuts the rubber sheet, the fixed cylinder 310 can drive the rubber block 320 to press against the support surface 101, thereby securing the movable frame 300 and preventing the movable frame 300 from moving out of position during the cutting process.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
