Description

Technical Field

[0001] The utility model relates to the technical field of printed matter die-cutting, in particular to a die-cutting device for printed matter processing. Background Technique

[0002] With the rapid development of the printing field, people can use printing technology to process a large number of beautiful printed matters. During the processing of these printed matters, die-cutting is required to cut these printed matters into sizes that meet production requirements.

[0003] According to Chinese Patent Publication No. CN215618397U, this patent provides a die-cutting device for printed matter processing, including a fixed frame and a movable rod. A die-cutting device is installed on the top of the fixed frame. A conveyor belt is installed on the top surface of the fixed frame. A push plate is arranged on the top surface of the conveyor belt. The movable rod is fixedly connected to one side of the push plate. The end of the movable rod away from the push plate is movably connected to a fixed plate. The fixed plate is fixedly connected to the side surface of the fixed frame. By setting a fixed plate on the fixed frame and cooperating with the movable rod on the fixed plate, the position of the printed matter is limited by the push plate and the baffle on the movable rod. Through the setting of the spring, it is convenient for the operator to place the printed matter between the baffle and the push plate, and at the same time, it also has the effect of limiting the placement of printed matters of different lengths.

[0004] The printed matter paper painting is fed by a winding roller. During the die-cutting process, the cutter can only die-cut the printed matter paper painting on a single winding roller. When the workload increases, the die-cutting efficiency will be reduced. In view of this, we propose a die-cutting device for printed matter processing. Content of the Utility Model

[0005] The purpose of the utility model is to provide a die-cutting device for printed matter processing, which solves the problem of low die-cutting efficiency of printed matter.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A die-cutting device for printed matter processing, including a support plate and a U-shaped seat. An adjusting part is installed on the support plate for adjusting multiple blades to cut simultaneously. A die-cutting part is installed on the adjusting part for cutting printed matter. A feeding part is installed on the U-shaped seat for installing and conveying printed matter.

[0008] Preferably, the adjusting part includes two support arms. One end of each of the two support arms is connected to the support plate, and the other ends of the two support arms are connected to a cross beam. A first motor is installed on the cross beam. The output end of the first motor is connected to a reciprocating lead screw. The reciprocating lead screw movably penetrates through the cross beam and extends downward. The support plate is connected with a mounting block. The extending end of the reciprocating lead screw is rotatably connected to the mounting block. A limiting rod is connected between the mounting block and the cross beam. A lead screw slider is slidably connected to the limiting rod, and the lead screw slider is simultaneously sleeved on the reciprocating lead screw in a threaded manner. The lead screw slider reciprocates along the reciprocating lead screw, thereby realizing the steps of expanding and resetting the die-cutting part.

[0009] Preferably, the die-cutting part includes a slide rod. The slide rod slidably penetrates through one of the support arms. One end of the slide rod close to the reciprocating lead screw is connected with a pressing arm. A spring is elastically connected between the pressing arm and the support arm. The other end of the slide rod is connected with a tool holder, and a cutting knife is installed on the tool holder. The elastic force of the spring pushes the pressing arm to reset, driving the cutting knife away from the cutting groove.

[0010] Preferably, there are two die-cutting parts. The other die-cutting part is symmetrically installed on the other support arm. Both ends of the pressing arms in the two die-cutting parts are arc-shaped structures. Both sides of the lead screw slider are arc-shaped structures. The lead screw slider is attached to the arc-shaped surfaces at one ends of the two pressing arms through its own arc-shaped surface. The arc-shaped structure can reduce the friction force, thereby ensuring that the pressing arms are smoothly expanded during the movement of the lead screw slider.

[0011] Preferably, the feeding part includes a second motor. The second motor is installed on one side of the outer wall of the U-shaped seat. One end of a rotating rod is connected to the output shaft of the second motor. The other end of the rotating rod movably penetrates between the inner walls of the U-shaped seat. Two first helical gears are sleeved on the penetrating end of the rotating rod. A partition is connected between the inner walls of the U-shaped seat. Two rotating shafts are rotatably connected to the bottom of the partition. Two second helical gears are sleeved on one ends of the two rotating shafts respectively. The two second helical gears are respectively meshed with the two first helical gears. The other ends of the two rotating shafts both movably penetrate through the top of the partition and are respectively installed with clamps. The clamps are convenient for clamping and unclamping the winding roller, facilitating the rapid replacement of the feeding by manpower.

[0012] Preferably, one end of the winding roller is clamped by each of the clamps. Cutting plates are connected to both ear ends of the U-shaped seat. The bottoms of the two cutting plates far away from the U-shaped seat are both connected to the support plate.

[0013] Preferably, limiting plates are installed on the sides of the two cutting plates close to each other. The limiting plates are both U-shaped structures. Cutting grooves are opened on the sides of the two cutting plates close to each other. In this case, the cutting knife is aligned with the cutting groove. The movable end of the printed matter continues to pass through the limiting plate and extend towards the cutting groove. The inner walls of the limiting plate limit the printed matter to prevent the printed matter from falling from the two cutting plates on both sides.

[0014] By means of the above technical solution, the utility model provides a die-cutting device for printed matter processing, which has at least the following beneficial effects:

[0015] (1) The utility model starts the motor to drive the reciprocating screw to drive the screw slider to reciprocate along the reciprocating screw. During the movement of the screw slider, the pressure arms on both sides are spread open, the slide bar pushes the tool holders on both sides, and at the same time pushes the cutter to cut the printed paper. After the screw slider contacts the mounting block, it is reset, and the cutter is reset away from the cutting groove to make the cut printed paper fall off. After the screw slider reciprocates once, two groups of printed products can be die-cut simultaneously, which doubles the work efficiency in batch operations.

[0016] (2) The utility model winds up the printed matter paper and picture by means of a winding roller, and inserts the winding roller into a corresponding fixture for installation. Then, the second motor is started to cause the rotating rod to drive the first bevel gear to rotate, and the meshing drives the second bevel gear to rotate, so that the winding rollers on the two fixtures drive the movable end of the printed matter to pass through the limit plate and extend toward the cutting groove until the printed matter paper and picture wound on the winding roller are cut. Then, the winding roller is pulled out from the fixture for replacement, thereby eliminating the steps of manually calibrating the screws for installing the material and improving the efficiency of loading and changing the material.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] See also Figures 1-5 The utility model provides a die-cutting device for processing printed materials, including a support plate 1 and a U-base 4. The support plate 1 and the U-base 4 serve as a base to support the device of this case. An adjusting part 2 is installed on the support plate 1 for adjusting multiple blades to cut simultaneously. The die-cutting part 3 is installed on the adjusting part 2 for cutting printed materials. The feeding part 5 is installed on the U-base 4 for installing and conveying printed materials. The adjusting part 2 includes two supporting arms 21. One end of the two supporting arms 21 is connected to the support plate 1. The other end of the two supporting arms 21 is connected to a cross beam 22. A motor 23 is installed on the cross beam 22. A reciprocating screw rod 24 is connected to the output end of the motor 23. The reciprocating screw rod 24 movably penetrates the cross beam 22 and extends downward. A mounting block 25 is connected to the support plate 1. The extended end of the reciprocating screw rod 24 is rotatably connected to the mounting block 25. A limiting rod 26 is connected between the mounting block 25 and the cross beam 22. A wire rod 26 is slidably connected to the limiting rod 26. The rod slider 27 is limited by the limit rod 26, and the problem of self-rotation dislocation will not occur. The screw slider 27 is also threadedly sleeved on the reciprocating screw 24. The die-cutting part 3 includes a slide rod 31, and the slide rod 31 slides through one of the support arms 21. The end of the slide rod 31 close to the reciprocating screw 24 is connected to a pressure arm 32, and a spring 33 is elastically connected between the pressure arm 32 and the support arm 21. The other end of the slide rod 31 is connected to a tool holder 34, and a cutter 35 is installed on the tool holder 34. There are two die-cutting parts 3, and the other die-cutting part 3 is symmetrically installed on the other support arm 21. Both ends of the pressure arms 32 in the two die-cutting parts 3 are arc structures, and both sides of the screw slider 27 are arc structures. The screw slider 27 fits with the arc surface of one end of the two pressure arms 32 through its own arc surface, and the screw slider 27 uses the arc surface to resist the arc surface of the pressure arm 32, and the pressure arms 32 on both sides are spread open during the movement of the screw slider 27.

[0026] In this embodiment, by starting the motor 1 23, the reciprocating screw 24 drives the screw slider 27 to reciprocate along the reciprocating screw 24. During the movement of the screw slider 27, the pressure arms 32 on both sides are stretched open, the slide bar 31 pushes the tool holders 34 on both sides, and at the same time pushes the cutter 35 to cut the printed paper. After the screw slider 27 contacts the mounting block 25, it is reset, and the cutter 35 is reset away from the cutting groove 9 to make the cut printed paper fall off. Example

[0027] Please refer to Figures 1-5 Based on the first embodiment, the present utility model provides a technical solution: Preferably, the feeding part 5 includes a second motor 51, the second motor 51 is installed on one side of the outer wall of the U-shaped seat 4, one end of a rotating rod 52 is connected to the output shaft of the second motor 51, and the other end of the rotating rod 52 movably penetrates between the inner walls of the U-shaped seat 4. Two first helical gears 53 are sleeved on the penetrating end of the rotating rod 52. A partition plate 54 is connected between the inner walls of the U-shaped seat 4. Two rotating shafts 55 are rotatably connected to the bottom of the partition plate 54. Two second helical gears 56 are sleeved on one ends of the two rotating shafts 55. The two second helical gears 56 are respectively meshed with the two first helical gears 53. The other ends of the two rotating shafts 55 both movably penetrate through the top of the partition plate 54 and are respectively installed with clamps 57. The clamps 57 are common three-jaw chucks in the prior art. One ends of the winding rollers 6 are clamped on the clamps 57. Cutting plates 7 are connected to both ear ends of the U-shaped seat 4. The bottoms of the two cutting plates 7 on the sides far from the U-shaped seat 4 are both connected to the support plate 1. Limiting plates 8 are installed on the sides of the two cutting plates 7 close to each other. The limiting plates 8 are both U-shaped structures. The movable ends of the printed matter on the two rollers are stretched, and the movable ends of the printed matter penetrate through the inner walls of the limiting plates 8 for limiting. Cutting grooves 9 are opened on the sides of the two cutting plates 7 close to each other.

[0028] In this embodiment, the printed matter paper painting is wound around the winding roller 6 and inserted and installed in the corresponding clamp 57. The second motor 51 is started to drive the rotating rod 52 to drive the first helical gear 53 to rotate, and the meshing drives the second helical gear 56 to rotate, so that the winding rollers 6 on the two clamps 57 drive the movable end of the printed matter to extend through the limiting plate 8 towards the cutting groove 9 until the printed matter paper painting wound on the winding roller 6 is cut. The winding roller 6 is pulled out from the clamp 57 for replacement.

[0029] Working principle: The printed matter paper painting is wound around the winding roller 6, and the two winding rollers 6 are respectively inserted into the corresponding clamps 57 for limiting. The clamp 57 is a common three-jaw chuck in the prior art, so it will not be elaborated here. After clamping the winding roller 6, the movable ends of the printed matter on the two rollers are stretched, and the movable ends of the printed matter penetrate through the inner walls of the limiting plates 8 for limiting to prevent falling from the two cutting plates 7 on both sides. At this time, the second motor 51 is started to drive the rotating rod 52 to drive the first helical gear 53 to rotate, and the meshing drives the second helical gear 56 to rotate, so as to drive the clamp 57 to rotate through the rotating shaft 55, so that the winding rollers 6 on the two clamps 57 rotate relative to each other, and then the movable end of the printed matter continues to penetrate through the limiting plate 8 towards the cutting groove 9. After the printed matter is extended to the appropriate length according to the die-cutting size requirements, the second motor 51 is stopped.

[0030] After the die-cutting size is determined in the above steps, the motor 23 is started to rotate the reciprocating screw 24 and drive the screw slider 27 to reciprocate along the reciprocating screw 24. The screw slider 27 is limited by the limit rod 26, and the problem of self-rotation and misalignment will not occur. The screw slider 27 uses the arc surface to resist the arc surface of the pressure arm 32, and the pressure arms 32 on both sides are spread apart during the movement of the screw slider 27, thereby squeezing the springs 33 of the pressure arms 32 on both sides to cause the slide bar 31 to push the tool holders 34 on both sides, and At the same time, the cutter 35 is pushed close to the adjacent printed paper. In this case, the cutter 35 is aligned with the cutting groove 9, and the cutter 35 can fit the front side of the limit plate 8 after moving, thereby ensuring the flatness and stability of the lower knife cutting. After the cutter 35 is pushed into the cutting groove 9, the printed paper is cut off at the same time, and the screw slider 27 contacts the mounting block 25 and resets. After resetting, the elastic force of the spring 33 pushes the pressure arm 32 to reset, thereby driving the cutter 35 away from the cutting groove 9, so that the cut printed paper falls and is recovered.

[0031] By using the above steps, the die-cutting operation of two groups of printed materials can be achieved simultaneously after the screw slider 27 reciprocates once, thereby improving work efficiency. The above first step is continued to be used, so that the motor 2 51 continues to work to push the movable end of the printed material to cover the cutting groove 9, and then the motor 1 23 is used to work to perform the cutting work until the printed paper wound on the winding roller 6 is cut. At this time, the winding roller 6 can be pulled out from the clamp 57 for replacement, which is convenient and quick, eliminating the steps of manually proofreading the screws and installing the material, thereby improving the efficiency of loading and changing materials.
