Description

Technical Field

[0001] This utility model relates to the technical field of flatbed die-cutting machine devices, specifically to an automatic pressure adjustment structure for a flatbed die-cutting machine. Background Technology

[0002] A flatbed die-cutting machine is a device that can cut printed materials or composite materials into specific shapes. This equipment uses a flatbed die for die-cutting; the blade mounted on the cutter head is controlled by a drive mechanism to cut the material.

[0003] However, traditional die-cutting machines do not have the function of automatically adjusting pressure during use. That is, if the pressure of the lifting action is too high when the die-cutting material is lifted for die-cutting, it will damage the die-cutting blade and affect production efficiency. In addition, there are certain defects in the replacement of the die-cutting blade of traditional die-cutting machines. The traditional blade replacement process is too cumbersome and takes too much time during disassembly, which affects the replacement efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed automatic pressure adjustment structure for a flat die-cutting machine, which can solve the above-mentioned defects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a base, a mounting frame is provided on the base, an upward pushing component is provided below the top plate of the mounting frame, a plurality of locking and clamping components are provided on the upward pushing component, and a replaceable die-cutting component is also provided on the mounting frame, the replaceable die-cutting component frame covering the upward pushing component.

[0006] Preferably, the upward pushing assembly includes a U-shaped frame fixedly connected to the mounting frame, a telescopic cylinder fixedly connected to the U-shaped frame, the bottom of the telescopic cylinder fixedly connected to the base, a movable frame fixedly connected to the output end of the telescopic cylinder, a T-shaped guide rail on both sides of the movable frame, a T-shaped guide rail groove on both inner side walls of the U-shaped frame, and the movable frame slidably connected to the U-shaped frame through the T-shaped guide rail.

[0007] Preferably, two buffer springs are provided between the movable frame and the mounting frame, and telescopic rods are provided inside the two buffer springs. The upper and lower ends of the telescopic rods are fixedly connected to the movable frame and the mounting frame, respectively.

[0008] Preferably, the top plate of the mounting frame is provided with two through slots, the side plates of the movable frame are movable within the through slots, and the two through slots correspond one-to-one with the T-shaped guide rail slots.

[0009] Preferably, the locking and clamping assembly includes a mounting base fixedly connected to the movable frame, a motor at the bottom of the mounting base, a support frame fixedly connected to the motor, the support frame fixedly connected to the movable frame, a vertical plate on the mounting base, a horizontal plate fixedly connected to the top of the vertical plate, a lead screw at the transmission end of the motor, the lead screw being rotatably connected to the mounting base and the horizontal plate, and a pressure plate movably mounted on the thread of the lead screw.

[0010] Preferably, two guide posts are provided between the horizontal plate and the mounting base, the clamping plate is slidably connected to the two guide posts, two T-shaped guide rails are provided on one side of the clamping plate, and two T-shaped guide rail grooves are provided on the vertical plate that match the T-shaped guide rails. The clamping plate is slidably connected to the vertical plate through the T-shaped guide rails.

[0011] Preferably, the replaceable die-cutting assembly includes several support legs fixedly connected to the mounting frame, and a shielding seat is provided on the several support legs. A cover plate is hinged to one side of the shielding seat, and the end of the cover plate away from the hinge is connected to the shielding seat by several bolts.

[0012] Preferably, the shielding seat has two grooves, and a T-shaped block is slidably disposed in the grooves. The T-shaped block is disposed through the shielding seat, and a die-cutting flat blade is disposed at the bottom of the T-shaped block.

[0013] The beneficial effects of this utility model after adopting the above structure are:

[0014] This invention, by setting up an upward pushing component, enables the flatbed die-cutting machine to control the pushing stroke of the movable frame top plate by controlling the stroke of the output end of the telescopic cylinder during operation. When the movable frame pushes upward, in conjunction with the telescopic rod and the buffer spring, the buffer spring is in a compressed state, thus enabling the die-cutting flatbed knife to automatically adjust the pressure when die-cutting the material. This reduces the pressure of the lifting action, preventing damage to the die-cutting flatbed knife and not affecting production efficiency.

[0015] This invention features a replaceable die-cutting assembly. When the die-cutting flat blade needs to be replaced, simply remove a few bolts, open the cover plate, replace the two T-blocks with the required ones, align them with the grooves, and close the cover plate to complete the die-cutting flat blade replacement. The entire die-cutting blade replacement process is faster and more efficient, without taking up too much time during disassembly or affecting the replacement efficiency.

[0016] This invention, by setting a locking clamping component, can achieve stable clamping of the die-cutting material, which facilitates subsequent die-cutting operations and makes the die-cut finished product more neat and perfect. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-7 As shown, the present invention proposes an automatic pressure adjustment structure for a flat die-cutting machine, which includes a base 1, a mounting frame 2 on the base 1, an upward pushing component 3 below the top plate of the mounting frame 2, a plurality of locking clamping components 4 on the upward pushing component 3, and a replaceable die-cutting component 5 on the mounting frame 2, which frames and covers the upward pushing component 3.

[0028] The upward pushing component 3 includes a U-shaped frame 31 fixedly connected to the mounting frame 2. A telescopic cylinder 32 is fixedly connected to the U-shaped frame 31. The telescopic cylinder 32 can push the movable frame 33 upward, so that the die-cutting material at the top plate of the movable frame 33 comes into contact with the die-cutting flat blade 56 for die-cutting. The bottom of the telescopic cylinder 32 is fixedly connected to the base 1. The output end of the telescopic cylinder 32 is fixedly connected to the movable frame 33. T-shaped guide rails 34 are provided on both sides of the movable frame 33. T-shaped guide rail grooves 35 are provided on both inner side walls of the U-shaped frame 31. The movable frame 33 is slidably connected to the U-shaped frame 31 through the T-shaped guide rails 34.

[0029] Two buffer springs 36 are provided between the movable frame 33 and the mounting frame 2. The two buffer springs 36 are provided with telescopic rods 38. The upper and lower ends of the telescopic rods 38 are fixedly connected to the movable frame 33 and the mounting frame 2 respectively.

[0030] The top plate of the mounting bracket 2 is provided with two through slots 37. The two side plates of the movable bracket 33 move within the through slots 37, and the two through slots 37 correspond to the T-shaped guide rail slot 35, which facilitates the up and down movement of the movable bracket 33.

[0031] The locking and clamping assembly 4 includes a mounting base 41 fixedly connected to the movable frame 33. A motor 42 is provided at the bottom of the mounting base 41. A support frame 43 is fixedly connected to the motor 42. The support frame 43 is fixedly connected to the movable frame 33. A vertical plate 44 is provided on the mounting base 41. A horizontal plate 45 is fixedly connected to the top of the vertical plate 44. A lead screw 46 is provided at the transmission end of the motor 42. The lead screw 46 is rotatably connected to the mounting base 41 and the horizontal plate 45. A pressure plate 47 is movably installed on the thread of the lead screw 46.

[0032] Two guide posts 48 are provided between the horizontal plate 45 and the mounting base 41. The clamping plate 47 is slidably connected to the two guide posts 48. Two T-shaped guide rails 49 are provided on one side of the clamping plate 47. Two T-shaped guide rail grooves 410 that match the T-shaped guide rails 49 are provided on the vertical plate 44. The clamping plate 47 is slidably connected to the vertical plate 44 through the T-shaped guide rails 49. Through the cooperation of the guide posts 48, the T-shaped guide rails 49 and the T-shaped guide rail grooves 410, the clamping plate 47 can be made stable during movement.

[0033] The replaceable die-cutting assembly 5 includes several support legs 51 fixedly connected to the mounting frame 2. A shielding seat 52 is provided on the several support legs 51. A cover plate 53 is hinged to one side of the shielding seat 52. The end of the cover plate 53 away from the hinge is connected to the shielding seat 52 by several bolts.

[0034] The shielding base 52 has two grooves 54, and a T-shaped block 55 is slidably disposed in the grooves 54. The T-shaped block 55 passes through the shielding base 52, and a die-cutting flat blade 56 is provided at the bottom of the T-shaped block 55.

[0035] The principle and usage process of this utility model:

[0036] When in use, the staff places the prepared die-cutting material on the top plate of the movable frame 33, and at the same time starts several motors 42. The transmission end of the motor 42 drives the lead screw 46 to rotate, and the pressure plate 47 located on the lead screw 46 will move at this time. With the cooperation of two guide pillars 48, two T-shaped guide rails 49 and T-shaped guide rail grooves 410, several pressure plates 47 will press and fix the die-cutting material, thus facilitating subsequent die-cutting operations.

[0037] After the die-cutting material is pressed and fixed, the operator starts the telescopic cylinder 32. The output end of the telescopic cylinder 32 pushes the movable frame 33 upward, thereby pushing the die-cutting material fixed on the top plate of the movable frame 33 to overlap with the die-cutting flat blade 56. Throughout the process, the T-shaped guide rails 34 on both sides of the movable frame 33 will move in the T-shaped guide rail grooves 35 on both sides of the U-shaped frame 31, thus stabilizing the push of the movable frame 33. Since there are two telescopic rods 38 between the bottom plate of the movable frame 33 and the top plate of the mounting frame 2, and buffer springs 36 are set on the outer periphery of the telescopic rods 38, the movable frame 33 can be effectively restored to its original position by the cooperation of the two devices. Moreover, the push stroke of the movable frame 33 can be controlled by controlling the stroke of the output end of the telescopic cylinder 32 from the outside, thus achieving the effect of automatic pressure adjustment.

[0038] When the worker needs to replace the die-cutting flat blade 56, he can first loosen the bolts connecting the cover plate 53 and the shielding seat 52, then remove the bolts, then open the cover plate 53 and take out the two T-blocks 55 from the groove 54. The replacement T-blocks 55 only have a different shape for the bottom die-cutting flat blade 56, so the replacement T-blocks 55 can be placed along the groove 54, with the bottom aligned with the top plate of the movable frame 33. Finally, the cover plate 53 is closed, and the bolts are tightened to secure the T-blocks 55 in place. The subsequent die-cutting operation can then be carried out. The operation process is now complete.

[0039] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
