Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a lightbox cloth cutting device with a correction function. Background Technology

[0002] Lightbox fabric, also known as inkjet printing fabric, is mainly made of PVC and is commonly used as a base for outdoor advertising inkjet printing. It can be divided into outer light fabric, inner light fabric, knife-coated fabric, and outer light sandwich fabric. There are various production processes for lightbox fabric, the most common of which are knife coating, lamination and calendering. Furthermore, the lightbox fabric needs to be cut during production, processing and packaging, at which point a cutting device is used to cut the lightbox fabric.

[0003] A search revealed Chinese patent CN212372234U, which discloses a cutting device for lightbox fabric rolls. This cutting device reduces the difficulty of cutting fabric rolls and improves production efficiency. It includes a cutting motor housing, a receiving basket, a fabric roll fixing seat, a cutting chamber, and a drive cylinder. The cutting motor housing is located on one side of the cutting chamber and has a linear cutting blade. The receiving basket is located below the linear cutting blade. The fabric roll fixing seat is positioned inside the cutting chamber via the drive cylinder. A slide rail is provided on the bottom surface of the cutting chamber. A pulley is provided at the lower end of the fabric roll fixing seat, with the lower part of the pulley embedded in the slide rail. A positioning component is provided at the upper end of the fabric roll fixing seat to position the fabric roll. When the fabric roll is placed on a conical cylinder, the outer wall of the fabric roll abuts against the side wall of the conical cylinder. Furthermore, an ejection mechanism is provided inside the cutting chamber to push the fabric roll between the conical cylinders.

[0004] However, the above design still has shortcomings. In the process of transmitting lightbox cloth, the design does not have the function of correcting the deviation of lightbox cloth, which makes it inconvenient to cut the lightbox cloth later and will reduce the accuracy of cutting.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a lightbox fabric cutting device with a correction function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lightbox fabric cutting device with a correction function, comprising a base, a fixed frame fixedly connected to the top left side of the base, through slots through both sides of the fixed frame, a telescopic cylinder fixedly installed at the top of the fixed frame, a transmission plate fixedly connected to the output end of the telescopic cylinder, a first forward and reverse motor fixedly installed inside the transmission plate, a threaded rod fixedly connected to the output end of the first forward and reverse motor, a threaded block threadedly connected to the outer wall of the threaded rod, a mounting plate fixedly connected to the bottom of the threaded block, a second forward and reverse motor fixedly installed inside the mounting plate, a bidirectional screw fixedly connected to the output end of the second forward and reverse motor, a moving block threadedly connected to the outer wall of the bidirectional screw, a crossbar movably disposed through the upper surface of the moving block, a transmission block fixedly connected to the bottom of the moving block, a connecting rod fixedly connected to the bottom of the transmission block, and a clamping frame fixedly connected to the bottom of the connecting rod.

[0008] As a further embodiment of this utility model: a U-shaped frame is fixedly installed on the upper surface of the base on the right side of the fixed frame, and a guide wheel is rotatably installed on the inner side of the U-shaped frame.

[0009] As a further embodiment of this utility model: a mounting frame is fixedly provided on the right side of the U-shaped frame, and a hydraulic push rod is fixedly installed on the top of the mounting frame.

[0010] As a further embodiment of this utility model: the output end of the hydraulic push rod is fixedly connected to a lifting plate, and the bottom of the lifting plate is fixedly connected to a cutter.

[0011] As a further embodiment of this utility model: the bottom of the cutter is provided with a matching cutting groove, and a soft rubber sleeve is detachably provided inside the cutting groove.

[0012] As a further embodiment of this utility model: a control panel is fixedly installed on the front end face of the base, and support blocks are fixedly connected to the four corners of the bottom of the base.

[0013] This utility model has the following beneficial effects:

[0014] Through the structural design of telescopic cylinder, fixed frame, through groove, transmission plate, threaded block, mounting plate, crossbar, bidirectional screw, transmission block, clamping frame, threaded rod, first forward and reverse motor, second forward and reverse motor, moving block and connecting rod, it is possible to easily adjust the vertical and horizontal of the transmitted lightbox cloth, thereby achieving the purpose of correction. This facilitates the subsequent cutting of the lightbox cloth and improves the cutting accuracy. At the same time, it is possible to reasonably adjust the distance between the two clamping frames, thereby facilitating better limiting and guiding of lightbox cloth of different widths, thereby improving the guiding effect. This solves the problem that the lightbox cloth does not have the function of correction during the transmission process, which makes it inconvenient to cut the lightbox cloth later and reduces the cutting accuracy.

[0015] Through the structural design of hydraulic push rods, lifting plates, cutters, mounting frames, guide wheels, U-shaped frames, cutting grooves, and soft rubber sleeves, the lightbox fabric can be guided by the guide wheels before cutting, making it easier to cut the fabric later. At the same time, the output end of the hydraulic push rod can drive the lifting plate to move downwards, which in turn drives the cutter downwards to cut the lightbox fabric. Furthermore, the soft rubber sleeve can prevent the cutter from directly contacting the inner wall of the cutting groove, thereby reducing the wear of the cutter and extending its service life.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5An embodiment of this utility model provides a lightbox cloth cutting device with a correction function, including a base 4, a fixed frame 2 fixedly connected to the top left side of the base 4, through slots 3 through both sides of the fixed frame 2, a telescopic cylinder 1 fixedly installed on the top of the fixed frame 2, a transmission plate 13 fixedly connected to the output end of the telescopic cylinder 1, a first forward and reverse motor 23 fixedly installed inside the transmission plate 13, a threaded rod 22 fixedly connected to the output end of the first forward and reverse motor 23, a threaded block 16 threadedly connected to the outer wall of the threaded rod 22, an mounting plate 17 fixedly connected to the bottom of the threaded block 16, a second forward and reverse motor 24 fixedly installed inside the mounting plate 17, a bidirectional screw 19 fixedly connected to the output end of the second forward and reverse motor 24, a moving block 25 threadedly connected to the outer wall of the bidirectional screw 19, a crossbar 18 movably arranged through the upper surface of the moving block 25, a transmission block 20 fixedly connected to the bottom of the moving block 25, a connecting rod 26 fixedly connected to the bottom of the transmission block 20, and a clamping frame 21 fixedly connected to the bottom of the connecting rod 26.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, during the transmission of the lightbox fabric, the fabric is located inside the two clamping frames 21. The output of the telescopic cylinder 1 drives the transmission plate 13 to move, which in turn moves the clamping frames 21, facilitating vertical height adjustment of the lightbox fabric. Furthermore, the output of the first forward / reverse motor 23 drives the threaded rod 22 to rotate, which in turn moves the threaded block 16, which in turn moves the mounting plate 17, which in turn moves the clamping frames 21, thus facilitating horizontal adjustment of the lightbox fabric. This allows for vertical and horizontal adjustment of the transmitted lightbox fabric, achieving the purpose of correction and facilitating subsequent cutting of the lightbox fabric. This improves the cutting accuracy and allows the output of the second forward and reverse motor 24 to drive the bidirectional screw 19 to rotate. The rotation of the bidirectional screw 19 drives two moving blocks 25 to move in directions that are closer or further apart from each other. The movement of the two moving blocks 25 drives two transmission blocks 20 to move. The movement of the two transmission blocks 20 drives two clamping frames 21 to move in directions that are closer or further apart from each other through two connecting rods 26. By reasonably adjusting the distance between the two clamping frames 21, it is easier to limit and guide lightbox cloth of different widths, thereby improving the guiding effect. This solves the problem that in the process of transmitting lightbox cloth, there is no function to correct the deviation of the lightbox cloth, which makes it inconvenient to cut the lightbox cloth later and reduces the cutting accuracy.

[0029] A U-shaped frame 12 is fixedly installed on the upper surface of the base 4 on the right side of the fixed frame 2. A guide wheel 11 is rotatably installed on the inner side of the U-shaped frame 12. An installation frame 10 is fixedly installed on the right side of the U-shaped frame 12. A hydraulic push rod 7 is fixedly installed on the top of the installation frame 10. A lifting plate 8 is fixedly connected to the output end of the hydraulic push rod 7. A cutter 9 is fixedly connected to the bottom of the lifting plate 8. A control panel 5 is fixedly installed on the front end of the base 4. Support blocks 6 are fixedly connected to the four corners of the bottom of the base 4.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, during use, before cutting the lightbox fabric, the guide wheel 11 can guide the lightbox fabric, making it easier to cut the lightbox fabric later. At the same time, the output end of the hydraulic push rod 7 can drive the lifting plate 8 to move downward, and the downward movement of the lifting plate 8 can drive the cutter 9 to move downward, thereby cutting the lightbox fabric. Furthermore, the soft rubber sleeve 15 can prevent the cutter 9 from directly contacting the inner wall of the cutting groove 14, thereby reducing the wear of the cutter 9 and extending the service life of the cutter 9.

[0031] Working principle: In this application, when cutting the lightbox fabric, the fabric is passed from left to back through the through groove 3, between the two clamping frames 21, the bottom of the guide wheel 11, and below the cutter 9, and finally fixed on the outer wall of the take-up roller. Then, the take-up motor is started to drive the take-up roller to rotate slowly. During the transmission process of the lightbox fabric, the fabric is located inside the two clamping frames 21. Then, the output end of the telescopic cylinder 1 can drive the transmission plate 13 to move. The movement of the transmission plate 13 ultimately drives the clamping frames 21 to move, thereby... The vertical height of the lightbox fabric can be adjusted, and the output of the first forward and reverse motor 23 can drive the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the threaded block 16 to move, the movement of the threaded block 16 drives the mounting plate 17 to move, and the movement of the mounting plate 17 ultimately drives the clamping frame 21 to move. This facilitates the adjustment of the horizontal position of the lightbox fabric. By facilitating the vertical and horizontal adjustment of the conductive lightbox fabric, the purpose of correction is achieved, which in turn facilitates the subsequent cutting of the lightbox fabric and improves the cutting accuracy. Secondly, the output of the second forward and reverse motor 24 drives the bidirectional screw 19 to rotate. The rotation of the bidirectional screw 19 drives the two moving blocks 25 to move in a direction that approaches or moves away from each other. The movement of the two moving blocks 25 drives the two transmission blocks 20 to move. The movement of the two transmission blocks 20 drives the two clamping frames 21 to move in a direction that approaches or moves away from each other through the two connecting rods 26. By reasonably adjusting the distance between the two clamping frames 21, it is easier to limit and guide lightbox fabrics of different widths, thereby improving the guiding effect. Finally, before cutting the lightbox fabric, the guide wheel 11 can guide the lightbox fabric, making it easier to cut the lightbox fabric later. At the same time, the output of the hydraulic push rod 7 drives the lifting plate 8 to move downward. The downward movement of the lifting plate 8 drives the cutter 9 to move downward, thereby cutting the lightbox fabric. Furthermore, the soft rubber sleeve 15 can prevent the cutter 9 from directly contacting the inner wall of the cutting groove 14, thereby reducing the wear of the cutter 9 and extending its service life.
