Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a safety protection mechanism for a flat pressure indentation wire cutting machine. Background Technology
[0002] A creasing machine, also known as a flatbed creasing and cutting machine, is a specialized piece of equipment used for creasing and cutting various types of ordinary cardboard, corrugated cardboard, plastic sheets, and leather products. It is suitable for use in the printing, packaging, decoration, and plastics industries.
[0003] In the prior art, such as the Chinese patent publication number CN216683562U, a flatbed creasing and slitting machine with a fixing function is disclosed. This machine includes a machine body, a pressure plate, a positioning component, and evenly distributed fixing components. The pressure plate is installed on the surface of the machine body, and the positioning components are installed inside the pressure plate, with their surface penetrating the pressure plate and extending to its exterior. This invention, by setting up the positioning component, allows the worker to measure the dimensions of the cardboard before processing it. The worker then rotates an adjusting rod based on these dimensions. The adjusting rod simultaneously rotates two external threads, causing them to drive two moving plates to move in opposite directions. The moving plates then move the limiting blocks until the distance between the two limiting blocks on the same horizontal plane is adjusted to match the worker's measurement. The worker can then place the cardboard between the two limiting blocks for creasing.
[0004] However, existing flatbed creasing and cutting machines require the cardboard to be placed inside two plates for cutting when cutting the cardboard. After the cardboard is cut, the operator needs to remove the cardboard from the two plates. This process poses a significant safety hazard. Therefore, a safety protection mechanism for the flatbed creasing and cutting machine is needed to solve this problem. Utility Model Content
[0005] The purpose of this invention is to provide a safety protection mechanism for a flat-press creasing and tangling machine, which has a high safety effect during the tangling process.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a safety protection mechanism for a flat-press creasing and tangling machine, comprising a machine body, a first plate fixedly connected to one side of the machine body, a rotating shaft rotatably connected to the other side of the machine body, a second plate fixedly connected to one end of the rotating shaft, a cylinder fixedly installed inside the first plate, a push plate fixedly connected to the output end of the cylinder, a tangling cutter fixedly installed on the outer side of the push plate, a limit rail fixedly connected to the outer side of the second plate, a sleeve fixedly connected to the edge of the second plate, a spring fixedly connected to the inner bottom wall of the sleeve, a mounting seat fixedly connected to the top of the spring, a top block fixedly connected inside the mounting seat, linear rails fixedly connected to both sides of the inner wall of the sleeve, the mounting seat slidably connected inside the linear rails, and a rubber block fixedly connected to one end of the top block.
[0007] By adopting the above technical solution, the first and second plates are symmetrical to each other. The second plate rotates around the pivot inside the machine body. When creasing and cutting the cardboard, the cardboard is first placed into the limiting track inside the second plate, so that the cardboard extends into the limiting track. Then, the cylinder is activated, which drives the push plate and the cutting blade to extend and retract. Through the displacement of the cutting blade, the cutting blade contacts the cardboard inside the limiting track, thereby creasing and cutting the cardboard. When the second plate opens and closes inside the first plate, the rubber block will contact the inside of the first plate. At this time, the spring will be compressed, and the mounting base drives the top block and the rubber block to extend and retract inside the linear track, thus leaving a gap between the first and second plates. When the worker's hand is put into the gap between the first and second plates, the gap setting can prevent the first and second plates from pinching and injuring the worker's hand, thus making the device extremely safe to use and reducing the occurrence of safety accidents.
[0008] A further feature of this invention is that the number of rubber blocks is two, and the two rubber blocks are distributed on both sides of the outer side of the second plate.
[0009] By adopting the above technical solution, the two rubber blocks are parallel to each other, and both rubber blocks are in contact with the inner side of the first plate.
[0010] A further feature of this invention is that a drive box is fixedly installed on the outside of the machine body, and an electric push rod is fixedly installed inside the drive box.
[0011] By adopting the above technical solution, a bracket adapted to the electric push rod is fixedly installed inside the drive box, thereby enabling the electric push rod to be fixed in the bracket inside the drive box.
[0012] A further feature of this invention is that the output end of the electric push rod is fixedly connected to a pulley seat, and a pulley is slidably connected inside the pulley seat.
[0013] By adopting the above technical solution, the electric push rod is activated, which drives the pulley seat and pulley to extend and retract.
[0014] A further feature of this invention is that a slide rail is fixedly connected to the back of the second plate, and the pulley extends into the interior of the slide rail and is slidably connected to the slide rail.
[0015] By adopting the above technical solution, the pulley seat is limited inside the slide rail, and the pulley is slidably connected inside the slide rail. When the electric push rod drives the pulley to extend, the pulley will move inside the slide rail. At this time, the second plate will rotate around the pivot, so that the second plate can open and close outside the first plate.
[0016] A further feature of this invention is that the interior of the body has a cavity, and a storage box is slidably connected inside the cavity.
[0017] By adopting the above technical solution, the storage box is installed inside the machine body through a cavity, and the working equipment is stored in the storage box.
[0018] A further feature of this invention is that a cover plate is fixedly connected to the outside of the storage box, and a handle is fixedly connected to the outside of the cover plate.
[0019] By adopting the above technical solution, the cover closes the storage box inside the machine body.
[0020] A further feature of this invention is that a base is fixedly connected to the bottom of the body, and an anti-slip pad is fixedly connected to the bottom of the base.
[0021] By adopting the above technical solution, the base and anti-slip pads support the machine body, improving the stability of the machine body during operation.
[0022] A further feature of this invention is that a cylinder frame is fixedly installed inside the first plate, and the cylinder is fixedly connected inside the cylinder frame.
[0023] By adopting the above technical solution, the cylinder is fixed inside the first plate by the cylinder bracket, which improves the stability of the cylinder during operation.
[0024] A further feature of this invention is that the first plate has heat dissipation holes inside.
[0025] By adopting the above technical solution, the heat dissipation holes can expel the high temperature generated by the cylinder during operation, preventing heat from accumulating inside the first plate.
[0026] The beneficial effects of this utility model are:
[0027] This invention, through the arrangement of a machine body, a first plate, a rotating shaft, a second plate, a cylinder, a push plate, a crisscross cutter, a limiting track, a sleeve, a spring, a mounting base, a top block, a linear track, and a rubber block, establishes that the first and second plates are symmetrical. The second plate rotates around the rotating shaft inside the machine body. When creasing and crisscrossing the cardboard, the cardboard is first placed into the limiting track inside the second plate, allowing the cardboard to extend into the limiting track. Then, the cylinder is activated, driving the push plate and the crisscross cutter to extend and retract. Through the displacement of the crisscross cutter, the crisscross cutter interacts with the cardboard inside the limiting track. The first and second plates make contact with each other, allowing for the creasing and cutting of the cardboard. When the second plate opens and closes inside the first plate, the rubber block contacts the inside of the first plate, causing the spring to contract. The mounting base then drives the top block and the rubber block to extend and retract within the linear track, creating a gap between the first and second plates. This gap prevents workers from getting their hands pinched when they put their hands into it, ensuring the device is highly safe and reducing the risk of accidents.
[0028] This invention utilizes an electric push rod, a pulley seat, a pulley, and a slide rail. Activating the electric push rod drives the pulley seat and pulley to extend and retract. The pulley seat is confined within the slide rail, and the pulley is slidably connected within the slide rail. When the electric push rod extends the pulley, the pulley travels within the slide rail. At this time, the second plate rotates around the pivot, allowing the second plate to open and close outside the first plate. Attached Figure Description

[0038] Reference Figure 1-6A safety protection mechanism for a flatbed creasing and tangling machine includes a body 1. A first plate 2 is fixedly connected to one side of the body 1, and a rotating shaft 3 is rotatably connected to the other side of the body 1. A second plate 4 is fixedly connected to one end of the rotating shaft 3. A cylinder 5 is fixedly installed inside the first plate 2, and a push plate 6 is fixedly connected to the output end of the cylinder 5. A tangling cutter 7 is fixedly installed on the outer side of the push plate 6. A limit rail 8 is fixedly connected to the outer side of the second plate 4. A sleeve 9 is fixedly connected to the edge of the second plate 4. A spring 10 is fixedly connected to the inner bottom wall of the sleeve 9, and a mounting base 11 is fixedly connected to the top of the spring 10. A top block 12 is fixedly connected inside the mounting base 11. Linear rails 13 are fixedly connected to both sides of the inner wall of the sleeve 9. The mounting base 11 slides... Connected inside the linear track 13, a rubber block 14 is fixedly connected to one end of the top block 12. The first plate 2 and the second plate 4 are symmetrical to each other. The second plate 4 rotates around the pivot 3 inside the machine body 1. When creasing and cutting the cardboard, the cardboard is first placed into the limiting track 8 inside the second plate 4, so that the cardboard extends into the limiting track 8. Then, the cylinder 5 is activated, which drives the push plate 6 and the cutting blade 7 to extend and retract. Through the displacement of the cutting blade 7, the cutting blade 7 contacts the cardboard inside the limiting track 8, thereby creasing and cutting the cardboard. When the second plate 4 opens and closes inside the first plate 2, the rubber block 14 will contact the inside of the first plate 2. At this time, the spring 10 will be retracted. The mounting base 11 causes the top block 12 and rubber block 14 to extend and retract within the linear track 13, creating a gap between the first plate 2 and the second plate 4. This gap prevents the worker's hand from being pinched when it enters the gap, ensuring the device's safety and reducing the risk of accidents. Two rubber blocks 14 are positioned on either side of the second plate 4, parallel to each other and in contact with the inner side of the first plate 2. A drive box 15 is fixedly mounted externally on the body 1, and an electric push rod is fixedly mounted inside the drive box 15. 16. A bracket adapted to the electric push rod 16 is fixedly installed inside the drive box 15, thereby fixing the electric push rod 16 in the bracket inside the drive box 15. The output end of the electric push rod 16 is fixedly connected to a pulley seat 17, and a pulley 18 is slidably connected inside the pulley seat 17. When the electric push rod 16 is activated, it drives the pulley seat 17 and the pulley 18 to extend and retract. A slide rail 19 is fixedly connected to the back of the second plate 4. The pulley 18 extends into the slide rail 19 and is slidably connected to the slide rail 19. The pulley seat 17 is limited inside the slide rail 19, and the pulley 18 is slidably connected inside the slide rail 19. When the electric push rod 16 drives the pulley 18 to extend, the pulley 18 will move inside the slide rail 19. At this time,The second plate 4 will rotate around the pivot 3, allowing it to open and close outside the first plate 2. The machine body 1 has an internal cavity, inside which a storage box 20 is slidably connected. The storage box 20 is installed inside the machine body 1 through the cavity to store the work equipment. A cover 21 is fixedly connected to the outside of the storage box 20, and a handle is fixedly connected to the outside of the cover 21. The cover 21 closes the storage box 20 inside the machine body 1. A base 22 is fixedly connected to the bottom of the machine body 1. An anti-slip pad is fixedly connected to the bottom of the base 22. The base 22 and the anti-slip pad support the machine body 1, improving the stability of the machine body 1 during operation. A cylinder frame 23 is fixedly installed inside the first plate 2, and the cylinder 5 is fixedly connected inside the cylinder frame 23. The cylinder 5 is fixed inside the first plate 2 by the cylinder frame 23, improving the stability of the cylinder 5 during operation. Heat dissipation holes are provided inside the first plate 2 to dissipate the high temperature generated by the cylinder 5 during operation, preventing heat accumulation inside the first plate 2.
[0039] In this invention, the first plate 2 and the second plate 4 are symmetrical. The second plate 4 rotates around the pivot 3 inside the machine body 1. When creasing and cutting the cardboard, the cardboard is first placed into the limiting track 8 inside the second plate 4, allowing the cardboard to extend into the limiting track 8. Then, the cylinder 5 is activated, causing the cylinder 5 to drive the push plate 6 and the cutting blade 7 to extend and retract. Through the displacement of the cutting blade 7, the cutting blade 7 contacts the cardboard inside the limiting track 8, thereby creasing and cutting the cardboard. When the second plate 4 opens and closes inside the first plate 2, the rubber block 14 will contact the inside of the first plate 2. At this time, the spring 10 will be contracted, and the mounting base 11 will drive the top block 12 and the rubber block 14 to extend and retract inside the linear track 13, thereby... A gap is left between the first plate 2 and the second plate 4. When a worker's hand is inserted into the gap between the first plate 2 and the second plate 4, the gap prevents the worker's hand from being pinched by the first plate 2 and the second plate 4, thus making the device extremely safe to use and reducing the occurrence of safety accidents. Activating the electric push rod 16 causes the electric push rod 16 to drive the pulley seat 17 and the pulley 18 to extend and retract. The pulley seat 17 is limited inside the slide rail 19, and the pulley 18 is slidably connected inside the slide rail 19. When the electric push rod 16 drives the pulley 18 to extend, the pulley 18 will travel inside the slide rail 19. At this time, the second plate 4 will rotate around the pivot 3, thus allowing the second plate 4 to open and close outside the first plate 2.
