Description

Technical Field

[0001] This utility model relates to the field of flexible material cutting technology, specifically to a pressure plate height adjustment device for a cutting head. Background Technology

[0002] When producing flexible materials such as fabrics, they need to be divided into small pieces or cut into the required shapes and sizes by cutting equipment for further processing. Due to the special nature of flexible materials, they need to be stretched during cutting to make them taut before being cut by the cutting blade.

[0003] Currently, a utility model patent with announcement number CN218666872U discloses a fabric cutting device. This patent uses a spring in conjunction with a lower pressure roller to press the fabric, so that the outer side of the fabric can be tensioned; then, a cutting blade cuts the tensioned fabric, which helps to improve the cutting efficiency and accuracy of the fabric.

[0004] In the above technical solution, after the fabric is pressed and positioned by the lower pressure roller, the fabric is in a tense state from a macroscopic perspective. At this time, when the fabric is cut by the cutting blade, the fabric at the cutting edge will undergo elastic displacement or rebound under tension, resulting in edge curling and other issues that affect the cutting quality and effect. Based on this, this application provides a pressure plate height adjustment device for the cutting head to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a pressure plate height adjustment device for a cutting head to solve the problem in the prior art that when cutting flexible materials, the fabric at the cutting edge is prone to elastic rebound, which affects the cutting quality and effect.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a pressure plate height adjustment device for a cutting head, including a main support, two side support plates, a mounting block and a drive blade assembly are provided on the main support, a connecting frame is provided between the tops of the two side support plates, and a cutting blade for cutting flexible materials is provided at the output end of the drive blade assembly. The mounting block is equipped with a pressure plate assembly that can slide vertically, and the pressure plate assembly is located outside the cutting blade; The connecting frame is equipped with a lifting module that limits the bottom of the pressure plate assembly and a limiting module that limits the top of the pressure plate assembly; The lifting module includes a positioning frame located at the bottom of the connecting frame, a base plate that can slide vertically on the positioning frame, and a limiting component that physically limits the base plate. The base plate limits the bottom of the pressure plate assembly.

[0007] The above technical solution restricts the position of the pressure plate assembly by using the lifting module and the limiting module, enabling the pressure plate assembly to limit the flexible material on the cutting path of the cutting blade. This allows the pressure plate assembly to physically limit the flexible material while maintaining a certain gap to avoid excessive friction.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the pressure plate assembly includes a pressure plate that slides on the outside of the cutting blade and a limiting plate. The limiting plate is located on the top of the pressure plate, and two connecting rods are provided on the top of the limiting plate. A top plate is fixed between the top ends of the two connecting rods, and a through hole for the cutting blade to move is provided on the top of the top plate. Two support blocks are provided on the outside of the mounting block. The top of the support blocks fits into the bottom of the top plate. The mounting block has movable holes for the connecting rod to move.

[0010] The above technical solution can restrict the flexible material on the cutting path of the cutting blade by means of the pressure plate.

[0011] Furthermore, the positioning frame includes a first connecting block disposed at the bottom of the connecting frame, a guide block disposed at the bottom of the first connecting block, a second connecting block disposed at the bottom of the guide block, and a support block disposed at the bottom of the second connecting block.

[0012] The above technical solutions can provide space for structural design.

[0013] Furthermore, a sliding hole is provided between the top of the guide block and the support block, and a sliding rod is slidably connected inside the sliding hole, with the bottom end of the sliding rod fixed to the top of the base plate; The top of the support plate can fit against the bottom of the limiting plate, and the height of the support plate is less than the height of the pressure plate.

[0014] The above technical solution enables the base plate to slide vertically in cooperation with the sliding rod and the sliding hole.

[0015] Furthermore, the limiting component includes an adjusting rod fixed to the top of the base plate, with vertically equidistant toothed grooves on the outer side of the adjusting rod, and an adjusting hole for sliding the adjusting rod between the top of the guide block and the support block. The support block is equipped with a first cylinder, and the piston end of the first cylinder is equipped with a toothed block. The toothed block has teeth on its outer side and can mesh with the tooth groove.

[0016] The above technical solution uses a first cylinder to push a toothed block, which then achieves the positioning of the adjusting rod through the meshing between the teeth and the groove.

[0017] Furthermore, the support block is provided with a mating block, and a pointing groove is provided on the side of the mating block near the adjusting rod. Both the left and right sides of the pointing groove are open. The tooth block has a pointing block on its outer side, and the pointing groove allows the pointing block to be inserted and slid.

[0018] Through the above technical solution, the tooth block can move smoothly with the sliding cooperation of the pointing block and the pointing groove.

[0019] Furthermore, the limiting module includes a vertical plate mounted on the connecting frame, a second cylinder mounted on the vertical plate, and a limiting plate mounted on the piston end of the second cylinder.

[0020] Through the above technical solution, the second cylinder can drive the top plate to move.

[0021] Furthermore, the top plate is L-shaped, with the side of the top plate away from the second cylinder located above the top plate.

[0022] The above technical solution enables the top plate to limit the top of the top plate.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. By setting a pressure plate assembly on the outside of the cutting blade, the pressure plate assembly can physically limit the flexible material around the cutting point of the cutting blade; thus, when the fabric at the cutting edge rebounds due to elasticity, its top can be restricted, which is beneficial to improving the quality and effect of cutting flexible materials. 2. With the cooperation of the lifting module and the limiting module, the minimum and maximum height of the pressure plate assembly can be limited, so that there is a certain gap between the pressure plate assembly and the flexible fabric. This prevents the pressure plate assembly from directly rubbing against the surface of the flexible material during cutting, reducing frictional resistance and avoiding excessive constraint. It also allows the flexible material to naturally fine-tune under the tension on the outside, thereby limiting the cutting edge while ensuring the basic state of the flexible material.

[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] Example: Reference Figure 1 A pressure plate height adjustment device for a cutting head includes a main support 1, on which two side support plates 2, a mounting block 4, and a drive blade assembly are provided. A connecting frame 3 is provided between the tops of the two side support plates 2. The output end of the drive blade assembly is provided with a cutting blade for cutting flexible materials. A pressure plate assembly 5 that can slide vertically is provided on the mounting block 4, and the pressure plate assembly 5 is located outside the cutting blade. A lifting module 6 that restricts the bottom of the pressure plate assembly 5 and a top limiting module 8 that restricts the top of the pressure plate assembly 5 are provided on the connecting frame 3. The lifting module 6 includes a positioning frame located at the bottom of the connecting frame 3, on which a bottom plate 72 that can slide vertically is provided, and a limiting component that physically limits the bottom of the bottom plate 72. The bottom plate 72 limits the bottom of the pressure plate assembly 5.

[0029] It should be noted that the drive assembly can drive the cutting blade to perform reciprocating linear motion. The drive assembly can be any structure capable of achieving reciprocating linear motion, such as an electric push rod driving the cutting blade. Specifically, it can be an eccentric wheel and a connecting rod structure. The rotation of the eccentric wheel drives one end of the connecting rod structure to perform circular motion. Under the limiting action of the pressure plate assembly 5 located outside the cutting blade, the other end of the connecting rod structure drives the cutting blade to perform vertical reciprocating linear motion. The technology of combining the eccentric wheel and the connecting rod structure to achieve reciprocating linear motion is a commonly used technical solution in modern industry and is a publicly available technology, so it will not be elaborated further.

[0030] refer to Figure 3 and Figure 6 The pressure plate assembly 5 includes a pressure plate 51 that slides on the outside of the cutting blade and a limiting plate 52. The pressure plate 51 can restrict the flexible material on the cutting path of the cutting blade. The limiting plate 52 is located on the top of the pressure plate 51. The top of the limiting plate 52 is provided with two connecting rods 53. A top plate 54 is fixed between the top ends of the two connecting rods 53. The top of the top plate 54 has a through hole for the cutting blade to move, so that the cutting blade can move normally and cut the flexible material. The mounting block 4 has two lifting blocks 55 on its outside. The top of the lifting blocks 55 fits against the bottom of the top plate 54, so that the lifting blocks 55 can limit the top plate 54. The mounting block 4 has a movable hole for the connecting rods 53 to move. With the sliding cooperation of the connecting rods 53 and the movable hole, the top plate 54, the pressure plate 51, and the limiting plate 52 can move up and down together.

[0031] refer to Figure 2 The positioning frame includes a first connecting block 61 at the bottom of the connecting frame 3, a guide block 62 at the bottom of the first connecting block 61, a second connecting block 63 at the bottom of the guide block 62, and a support block 64 at the bottom of the second connecting block 63. By arranging them vertically, they can provide space for structural installation.

[0032] refer to Figure 2 and Figure 4 A sliding hole is provided between the top of the guide block 62 and the support block 64. A sliding rod 71 is slidably connected inside the sliding hole. The bottom end of the sliding rod 71 is fixed to the top of the base plate 72, so that the base plate 72 can slide vertically with the cooperation of the sliding rod 71 and the sliding hole. The top of the base plate 72 can fit against the bottom of the limiting plate 52. The height of the base plate 72 is less than the height of the pressure plate 51, so that the base plate 72 can lift the limiting plate 52 and limit the position of the pressure plate 51. This allows the gap between the pressure plate 51 and the flexible material to be controlled. In this state, the bottom of the base plate 72 is above the bottom of the pressure plate 51 and does not fit against the surface of the flexible material.

[0033] refer to Figure 2 and Figure 5 The limiting component includes an adjusting rod 73 fixed to the top of the base plate 72. The adjusting rod 73 has vertically spaced toothed grooves 74 on its outer side. An adjusting hole for sliding the adjusting rod 73 is provided between the top of the guide block 62 and the support block 64. The support block 64 is provided with a first cylinder 75. The piston end of the first cylinder 75 is provided with a toothed block 76. The toothed block 76 has teeth on its outer side and can mesh with the toothed grooves 74. By pushing the toothed block 76 with the first cylinder 75, the toothed block 76 meshes with the corresponding toothed grooves 74 through its teeth. The position of the adjusting rod 73 can be positioned by the meshing between the teeth and the toothed grooves 74, thus completing the position positioning of the base plate 72.

[0034] In use, move the toothed block 76 away from the tooth groove 74, use your hand to move the pressure plate 51 to a height that meets your needs, start the first cylinder 75 to push the toothed block 76 close to the adjusting rod 73, and lock it by meshing between the teeth and the tooth groove 74, thus positioning the pressure plate 51.

[0035] refer to Figure 2 The support block 64 is provided with a mating block 77. The mating block 77 has a guide groove on the side near the adjusting rod 73. Both sides of the guide groove are open. The toothed block 76 has a guide block 78 on its outer side. The guide groove allows the guide block 78 to be inserted and slide. With the sliding cooperation between the guide block 78 and the guide groove, the toothed block 76 can move smoothly, thereby improving the smoothness of the toothed block 76 when it is driven to move by the first cylinder 75.

[0036] refer to Figure 2 and Figure 7 The top limiting module 8 includes a vertical plate 81 mounted on the connecting frame 3. A second cylinder 82 is mounted on the vertical plate 81. A top limiting plate 83 is mounted on the piston end of the second cylinder 82. The second cylinder 82 can drive the top limiting plate 83 to move vertically.

[0037] refer to Figure 6 and Figure 7 The top plate 83 is L-shaped, and the side of the top plate 83 away from the second cylinder 82 is located above the top plate 54, so that the top plate 83 can limit the top of the top plate 54, thereby limiting the maximum height of the top plate 54.

[0038] In use, the second cylinder 82 is activated, which moves the top plate 83 to any height, thus limiting the maximum height of the top plate 54 and making it the maximum height limit point. This prevents the operator from lifting the pressure plate 51 too high when adjusting the pressure plate 51, which would result in an excessive gap between the pressure plate 51 and the flexible material, failing to meet the physical limit requirements.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
