Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box production technology, and in particular to a die-cutting machine for packaging box production. Background Technology
[0002] Die-cutting machines, also known as die-cutting boxes or die-pressing machines, are a type of mechanical equipment widely used in the printing and packaging industry. They are mainly used for die-cutting and creasing various sheets. A die-cutting machine generally consists of several parts, including the machine body, transmission system, die-cutting mechanism, and creasing device. The die-cutting mechanism uses steel blades and wires to precisely cut materials such as paper and cardboard according to the pre-designed shape and size, thereby creating the prototype of various packaging boxes, labels, and other printed materials. The creasing device can press creases on the surface of the material to facilitate subsequent folding and forming processes.
[0003] According to the patent document with publication number CN219856184U, the patent document limits the movement of the cardboard by protrusions on the outer wall of the pressure plate. The pressure plate is driven to move back and forth by the eccentric pull of the drive motor, connecting rod and turntable, so that the fixed template and the pressure plate close and separate, completing the die cutting and creasing of the cardboard. During this process, the push block in the transmission mechanism provides an upward push to the cardboard located on the outer wall of the pressure plate, so that the end of the cardboard automatically moves out of the end part of the pressure plate.
[0004] The patent document states that when die-cutting different types of cardboard using a fixed template, tools are usually needed to disassemble and replace multiple dies one by one. When processing the same type of cardboard again, it is still necessary to install and adjust the position accuracy of the dies, which is troublesome and affects the die-cutting accuracy. Utility Model Content
[0005] The purpose of this invention is to provide a die-cutting machine for producing packaging boxes in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A die-cutting machine for producing packaging boxes includes a fixed template, a movable template on one side of the fixed template, a transmission mechanism on the lower side of the movable template, a steel blade on one side of the fixed template, and a clamping mechanism for changing.
[0008] The clamping mechanism includes four support rods, all of which are rotatably connected to one side of the fixed template. Each of the four support rods has a sliding rod slidably connected to the side of the steel blade plate. Each of the four sliding rods has a clamping plate fixed to the end of the end of the sliding rod near the steel blade plate. Each of the four sliding rods has a spring sleeved on the outside. One end of the spring is fixedly connected to the clamping plate, and the other end of the spring is fixedly connected to the support rod. A stop is fixed to one side of the fixed template.
[0009] Preferably, the transmission mechanism includes a support frame, a rotating shaft is rotatably connected to the top of the support frame, a worm gear is fixed to the outside of the rotating shaft, and a worm is engaged at the bottom of the worm gear.
[0010] Preferably, cams are fixed at both ends of the rotating shaft, and connecting rods are hinged between the protruding side of the two cams and the front and rear sides of the moving template.
[0011] Preferably, a motor is fixedly installed at the worm gear input end, and protective covers for shielding the two cams are fixed on both the front and rear sides of the fixed template.
[0012] Preferably, the bottom of the moving template is hinged to the support frame, and the fixed template is fixed to the top of the support frame.
[0013] Preferably, a square groove for placing and replacing the clamping mechanism is provided on one side of the fixed template, and a rotating groove for cooperating with four sliding rods is provided at the four corners of the square groove.
[0014] Preferably, all four support rods are provided with grooves for engaging with the sliding rod.
[0015] The advantages compared with the existing technology are as follows: by placing the steel blade between the four clamping plates, the steel blade presses against the four clamping plates, and then the four clamping plates drive the sliding rod to move away from the steel blade. During this process, the four springs are compressed and react on the clamping plates, so that the four clamping plates clamp the steel blade, avoiding the back and forth disassembly of the steel blade, improving the positional accuracy of die cutting, facilitating replacement, and being applicable to steel blades of different sizes.

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.
[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] like Figures 1-8 As shown, a die-cutting machine for producing packaging boxes includes a fixed template 1, a movable template 2 on one side of the fixed template 1, a transmission mechanism 3 on the lower side of the movable template 2, a steel blade 5 on one side of the fixed template 1, and a clamping mechanism 4 for changing.
[0030] In this embodiment: the replacement clamping mechanism 4 includes four support rods 401, all of which are rotatably connected to one side of the fixed template 1. A square groove for placing the replacement clamping mechanism 4 is provided on one side of the fixed template 1. Rotary grooves that mate with four sliding rods 402 are respectively provided at the four corners of the square groove. Sliding rods 402 are slidably connected to the side of each support rod 401 near the steel blade plate 5. Each support rod 401 has a sliding groove for mates with the sliding rod 402. A clamping plate 403 is fixed to the end of each sliding rod 402 near the steel blade plate 5. Springs 404 are fitted on the outer sides of the four sliding rods 402. One end of the spring 404 is fixedly connected to the clamping plate 403, and the other end of the spring 404 is fixedly connected to the support rod 401. A stop 405 is fixed on one side of the fixed template 1. By placing the steel blade 5 between the four clamping plates 403, the steel blade 5 presses the four clamping plates 403, and then the four clamping plates 403 drive the sliding rods 402 to move away from the steel blade 5. During this process, the four springs 404 are compressed and react with the clamping plates 403, so that the four clamping plates 403 clamp the steel blade 5.
[0031] In this embodiment: the transmission mechanism 3 includes a support frame 301, a rotating shaft 302 rotatably connected to the top of the support frame 301, a worm gear 303 fixed to the outside of the rotating shaft 302, a worm 304 meshing with the bottom of the worm gear 303, cams 305 fixed to both ends of the rotating shaft 302, connecting rods 306 hinged between the protruding side of the two cams 305 and the front and rear sides of the moving template 2, a motor fixedly installed at the input end of the worm 304, and two shielding rods 306 fixed to the front and rear sides of the fixed template 1. The protective cover of cam 305, the bottom of the moving template 2 is hinged to the support frame 301, and the fixed template 1 is fixed to the top of the support frame 301. The worm 304 is driven to rotate by the motor. The worm 304 and the worm wheel 303 mesh, and the worm 304 drives the worm wheel 303 and the rotating shaft 302 to rotate, thereby driving the two cams 305 to rotate. The rotation of the cams 305 pulls the connecting rod 306 to drive the moving template 2 to rotate. The moving template 2 squeezes the fixed template 1, and the steel blade 5 completes the die cutting of the cardboard.
[0032] Working principle: Select the appropriate steel blade 5 according to the die-cutting requirements of the cardboard, and place the steel blade 5 between the four clamping plates 403. The steel blade 5 presses against the four clamping plates 403, which in turn causes the four clamping plates 403 to move the sliding rods 402 away from the steel blade 5. The four sliding rods 402 slide in the grooves of the corresponding support rods 401. During this process, the four springs 404 are compressed and react against the clamping plates 403, so that the four clamping plates 403 clamp the steel blade 5. Place the cardboard on top of the moving template 2, with the other side of the cardboard abutting against the three protrusions on the top of the moving template 2. The motor drives the worm gear 304 to rotate, and the worm gear 304 meshes with the worm wheel 303. The worm gear 304 then drives the worm wheel 303 and the rotating shaft 302 to rotate, thereby driving the two cams 305 to rotate. The rotation of the cams 305 pulls the connecting rod 306, which drives the moving template 2 to rotate. The moving template 2 presses against the fixed template 1, and the steel blade 5 completes the die-cutting of the cardboard.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
