Description

Technical Field

[0001] The present invention relates to the technical field of paper processing devices, and particularly to an indentation machine paper jam processing structure for a leatherette jewelry box. Background Art

[0002] In the current jewelry packaging field, leatherette is widely used in the production of jewelry boxes due to its leather-like texture, good strength, and diverse processing properties. The indentation process is a key link in the production of leatherette jewelry boxes and is crucial for improving the quality of jewelry boxes.

[0003] However, there are many deficiencies in the actual operation of existing indentation machines for leatherette jewelry boxes. During the transportation and processing of leatherette, the head of the paper often warps upwards, which makes the front end of the paper extremely likely to top against the paper feeding side of the device in the next processing step, thereby causing paper jams. Paper jams not only seriously affect the working efficiency of the indentation machine but also lead to damage to the leatherette, increasing production costs. At the same time, static electricity is easily generated during the processing of leatherette, which adsorbs dust and impurities, affecting product quality. Moreover, there may be wrinkles on the paper surface, affecting the indentation effect, and the paper corners are also prone to offset, making it difficult to ensure the indentation accuracy.

[0004] Although some existing indentation machines have taken improvement measures, for the paper jam problem caused by the upward warping of the paper head, generally, the jammed paper is removed by disassembling the knife beam. This method causes the indentation machine to be in a shutdown state for a long time, affecting the indentation efficiency of leatherette.

[0005] Therefore, it is necessary to design an indentation machine paper jam processing structure for a leatherette jewelry box to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose an indentation machine paper jam processing structure for a leatherette jewelry box.

[0011] Preferably, the feeding component includes two rotating rods rotatably connected to the adjacent sides of the two square blocks. Feeding rollers are fixedly connected to the two rotating rods.

Compared with the prior art, through the setting of the humidity sensor and the connection component, the present invention can monitor the humidity of the surrounding environment in real time. When the environmental humidity is low, control multiple winding wheels to rotate to release more wires, increasing the contact area between the wire and the ground, thereby enhancing the grounding effect and effectively coping with the static electricity problem caused by the dry environment. When the environmental humidity is high, only a small number of winding wheels release wires or the wires are all wound on the winding wheels, making the whole device cleaner.

[0016] In summary, through the collaborative innovative design of multiple components such as feeding, smoothing, corner pressing, and static elimination, the present invention comprehensively and effectively solves a series of problems existing in the existing leatherized paper jewelry box indentation machine, such as the paper head warping and jamming, unstable feeding, poor indentation quality, and static interference. It significantly improves the production efficiency, reduces the production cost, greatly enhances the production quality of the leatherized paper jewelry box, and has outstanding substantive features and remarkable progress.

Detailed implementation manners

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Refer to Figures 1-6, a paper jam processing structure of a creasing machine for a leather-filled paper jewelry box, comprising a fixed frame 1, a creasing assembly is arranged in the fixed frame 1, the creasing assembly comprises a lower cutting die 19 fixedly connected to the inner bottom of the fixed frame 1, two hydraulic cylinders 2 are fixedly connected to the inner top of the fixed frame 1, and an upper cutting die 3 is fixedly connected to the telescopic ends of the two hydraulic cylinders 2. The creasing assembly is used to creasing the leather-filled paper, and the lower cutting die 19 is used to provide a supporting surface for creasing. The upper cutting die 3 can move downward under the drive of the two hydraulic cylinders 2, and cooperate with the lower cutting die 19 to apply pressure to the leather-filled paper placed therebetween, thereby achieving creasing of the leather-filled paper. The structure of the upper and lower cutting dies cooperating can ensure the accuracy and quality of the creasing, and a top plate 4 is fixedly connected to the front side of the fixed frame 1, and two square blocks are fixedly connected to the front side of the fixed frame 1, and a feeding assembly is commonly arranged on the two square blocks, and the feeding assembly is used to feed the leather-filled paper to the creasing assembly For internal conveying, the feeding component can smoothly feed the leather-filled paper into the creasing component at the set speed and direction, ensuring that the position of the leather-filled paper is accurate when entering the creasing area, providing good prerequisites for subsequent creasing operations. The front sides of the two square blocks are commonly fixedly connected with a placement table 5, and a smoothing component is provided at the lower end of the top plate 4. The smoothing component is used to smooth the leather-filled paper. The smoothing component includes a pneumatic rod 21 fixedly connected to the lower end of the top plate 4, and the lower end of the pneumatic rod 21 is fixedly connected to a rectangular plate 22. The lower end of the rectangular plate 22 is rotatably connected to two connecting blocks 15. The lower ends of the two connecting blocks 15 are rotatably connected to a mounting frame 16. Smoothing rollers 20 are installed on the two mounting frames 16. The two smoothing rollers 20 are both made of rubber material. The pneumatic rod 21 can accurately control the lifting and lowering of the rectangular plate 22, thereby driving the connecting block 15, the mounting frame 16 and the smoothing roller 20 to move up and down. The rubber smoothing roller 20 has good flexibility and elasticity. When it comes into contact with the leather-filled paper, it can effectively fit the surface of the paper and eliminate wrinkles on the surface of the paper by rolling, making the surface of the leather-filled paper smoother and preparing for subsequent processing steps. A corner pressing component is provided at the upper end of the placement table 5. The corner pressing component is used to press the two left corners of the leather-filled paper after the smoothing component smoothes the leather-filled paper. After the leather-filled paper is smoothed, the corner pressing component can press the two left corners of the paper in time to prevent the corners of the paper from curling up during the subsequent transportation process, thereby ensuring the stability and accuracy of the paper during transportation, which is beneficial to improving the quality and efficiency of indentation.

[0021] Among them, the pressing assembly includes two moving grooves 26 provided on the placing tabletop 5. The front and rear inner walls of the two moving grooves 26 are jointly rotatably connected with a lead screw 14. Both lead screws 14 are threadedly connected with L-shaped blocks 18. The two L-shaped blocks 18 are slidably connected with the inner walls of the corresponding moving grooves 26. The right sides of the two L-shaped blocks 18 are fixedly connected with first electromagnets 33. The lower ends of the two first electromagnets 33 are fixedly connected with two telescopic rods 34. The telescopic ends of each two cooperating telescopic rods 34 are jointly fixedly connected with a pressing plate 36. The pressing plate 36 is made of a magnetic material. After the first electromagnet 33 is energized, it can generate magnetism and attract the pressing plate 36 to move downward to press the two corners of the leather-like paper. The adjacent sides of the two pressing plates 36 and the corresponding first electromagnets 33 are elastically connected by first springs 35. An infrared distance sensor 24 is installed at the lower end of the rectangular plate 22. A controller (not shown) is provided on the top plate 4. After the pneumatic rod 21 is stretched to the limit length, at this time, the electrical signal generated by the infrared distance sensor 24 is transmitted to the controller, and the controller controls the two first electromagnets 33 to be energized. Sliding grooves 27 are provided on the adjacent sides of the two moving grooves 26. Moving plates 37 are slidably connected in the two sliding grooves 27. The adjacent sides of the moving plates 37 and the corresponding pressing plates 36 are relatively rough, so that after the leather-like paper is clamped, it can drive the leather-like paper to move. Connecting pieces 38 are fixedly connected to the rear sides of the two L-shaped blocks 18. The two connecting pieces 38 are fixedly connected to the corresponding moving plates 37. A pressure sensor is installed at the rear side of the sliding groove 27 on the left side. When the pressure sensor is squeezed by the moving plate 37, it will generate an electrical signal and transmit it to the controller, and the controller controls the first electromagnet 33 to be powered off. The distance between the two corner pressing assemblies is greater than the length of the feeding roller 7, so that the rear side of the leather-like paper can be moved between the two feeding rollers 7.

[0022] Among them, the feeding assembly includes two rotating rods 6 rotatably connected to the adjacent sides of two square blocks. Feeding rollers 7 are fixedly connected to both rotating rods 6. The left sides of the two rotating rods 6 penetrate through the corresponding square blocks and are fixedly connected with rotating gears 8. The two rotating gears 8 mesh with each other. A first motor 17 is installed on the square block on the right side. The end of the output shaft of the first motor 17 is fixedly connected with the rotating rod 6 located above. The first motor 17 serves as a power source to drive the rotating rod 6 located above to rotate. Through the two meshing rotating gears 8, the power is transmitted to the rotating rod 6 located below, so that the two rotating rods 6 rotate synchronously, and then drive the feeding rollers 7 to rotate. The rotation of the feeding rollers 7 can smoothly convey the leather-like paper to the indentation assembly, realizing the automatic feeding process of the leather-like paper.

[0023] Among them, two mounting blocks 10 are fixedly connected to the left side of the placement table 5, and a transmission rod 11 is rotatably connected to the two mounting blocks 10. The transmission rod 11 and the rotating rod 6 located below are both provided with a bevel gear 9, and the two bevel gears 9 are meshed with each other. The front sides of the two screw rods 14 extend to the outside, and the two screw rods 14 are connected through the second transmission assembly 13. The transmission rod 11 and the screw rod 14 located on the left are connected through the first transmission assembly 12. The threaded layers on the two screw rods 14 are reciprocating threaded layers, so that the leather-filled paper can be reset after feeding. The first transmission assembly 12 includes a first sprocket arranged on the transmission rod 11 and the screw rod 14, and the two first sprockets are connected through a first chain transmission. The second transmission assembly 13 includes a second sprocket arranged on the two screw rods 14, and the two second sprockets are connected through a second chain transmission.

[0024] Among them, the placement table 5 is made of metal material, and a plurality of static elimination components are arranged at the lower end of the placement table 5. The static elimination components include two fixed blocks 28 fixedly connected to the lower end of the placement table 5. The adjacent sides of the two fixed blocks 28 are connected to a cross bar 31 for rotation together. A winding wheel 29 is fixedly connected to the cross bar 31. A wire 30 is wound around the winding wheel 29. One end of the wire 30 is fixedly connected to the lower end of the placement table 5. Both ends of the cross bar 31 pass through the two fixed blocks 28. The cross bar 31 is elastically connected to the fixed block 28 on the right side through a torsion spring 32. A second motor 25 is installed at the lower end of the placement table 5. The end of the output shaft of the second motor 25 is fixedly connected to the cross bar 31 on the left side. Two adjacent static elimination components are connected through a connecting component. The metal placement table 5 itself has certain conductive properties and can assist in the release of static electricity. Multiple static electricity elimination components work together, and the second motor 25 can drive the cross bar 31 on the left to rotate. When the cross bar 31 rotates, it drives the winding wheel 29 to rotate, thereby releasing or retracting the wire 30. The function of the connecting component is to connect multiple static electricity elimination components together, so that when necessary, multiple static electricity elimination components can work together to enhance the effect of static electricity elimination and improve the ability of the equipment to deal with static electricity problems under different environmental humidity.

[0025] The connection assembly includes an insertion slot 42 arranged on the right side of the left crossbar 31, a rectangular slot is arranged on the left side of the right crossbar 31, a second electromagnet 39 is fixedly connected to the inner wall of the rectangular slot, an insertion block 41 is slidably connected in the rectangular slot, the insertion block 41 is elastically connected to the adjacent side of the second electromagnet 39 through a second spring 40, and a humidity sensor 23 is installed at the lower end of the top plate 4, the humidity sensor 23 can monitor the humidity of the environment in real time, and feed back the humidity signal to the controller. The controller controls the power on and off of the second electromagnet 39 (controlled from left to right in sequence) and the operating state of the second motor 25 according to the humidity signal, thereby realizing automatic adjustment of the working mode of the static elimination assembly to meet the static elimination needs under different humidity environments.

[0026] The functional principle of the present invention can be described through the following operating mode: First, place the artificial leather paper flat on the placement table 5 made of metal material. At this time, the pneumatic rod 21 at the lower end of the top plate 4 is activated, and the pneumatic rod 21 drives the rectangular plate 22 at its lower end to move downward. The lower end of the rectangular plate 22 drives the mounting frame 16 rotatably connected to the lower end of the connecting block 15 through two rotatably connected connecting blocks 15 at its lower end, so that the two rubber smoothing rollers 20 on the mounting frame 16 come into contact with the surface of the artificial leather paper. Under the continuous action of the pneumatic rod 21, the smoothing rollers 20 roll on the surface of the artificial leather paper, performing a detailed and comprehensive smoothing operation on the paper, effectively eliminating the wrinkles on the paper surface and at the same time preventing the head of the paper from warping, providing a flat paper basis for subsequent processing.

[0027] After the pneumatic rod 21 is stretched to the longest distance, at this time the infrared distance sensor 24 generates an electrical signal and transmits it to the controller, and the controller controls the two first electromagnets 33 to be energized. After the two first electromagnets 33 are energized, they generate a repulsive force on the pressure plate 36, causing the two pressure plates 36 to move downward, thereby pressing the rear two corners of the artificial leather paper against the moving plate 37.

[0028] After the pressure plate 36 presses the two corners of the artificial leather paper, start the first motor 17. The output shaft of the first motor 17 drives the upper rotating rod 6 to rotate. Through the meshing rotating gears 8, the lower rotating rod 6 rotates synchronously. The feeding rollers 7 fixedly connected to the two rotating rods 6 start to rotate under the drive of the rotating rods 6.

[0029] At the same time, the rotation of the rotating rod 6 is transmitted to the lead screw 14 through the bevel gears 9, the first transmission assembly 12 and the second transmission assembly 13, driving the lead screw 14 to rotate. When the lead screw 14 rotates, the L-shaped block 18 threadedly connected thereto moves in the feeding direction under the action of the lead screw 14 because it is slidably connected to the inner wall of the moving groove 26, thereby pushing the rear side of the artificial leather paper with the two corners pressed to gradually move between the two feeding rollers 7.

[0030] When the artificial leather paper contacts the pressure sensor behind the left sliding groove 27, the pressure sensor generates an electrical signal and transmits it to the controller. After receiving the electrical signal from the pressure sensor, the controller controls the first electromagnet 33 to be powered off. The first electromagnet 33 loses magnetism, and the pressure plate 36 separates from the artificial leather paper under the action of the first spring 35. At this time, the two feeding rollers 7 continue to rotate under the drive of the first motor 17, and convey the artificial leather paper to the indentation assembly in the fixed frame 1.

[0031] The indentation assembly consists of a lower die 19 at the bottom inside the fixed frame 1 and an upper die 3 driven by two hydraulic cylinders 2 at the top inside. When the artificial leather paper is conveyed in place, the telescopic ends of the two hydraulic cylinders 2 push the upper die 3 downward to cooperate with the lower die 19 to perform an indentation treatment on the artificial leather paper.

[0032] In addition, during the feeding process, since there is a reciprocating thread layer on the lead screw 14, as the lead screw 14 rotates, the L-shaped block 18 will move in the opposite direction within the moving groove 26, causing the corner pressing assembly to reset and preparing for the next corner pressing operation on a new piece of leatherette paper.

[0033] During the entire leatherette paper processing, static elimination is an important step. The static elimination assembly at the lower end of the placement table 5 continuously operates, and its working mechanism is closely related to the environmental humidity. The humidity sensor 23 installed at the lower end of the top plate 4 continuously monitors the humidity of the surrounding environment.

[0034] When the humidity sensor 23 detects that the environmental humidity is low, it indicates that the possibility of static electricity generation is relatively high. The humidity sensor 23 transmits a signal to the controller. After receiving the signal, the controller controls the second electromagnet 39 in multiple connecting components to be energized (the lower the humidity, the number of second electromagnets 39 controlled increases sequentially from left to right, so that the static elimination components are connected together sequentially from left to right). Specifically, the insertion slot 42 on the right side of the left cross bar 31 cooperates with the structure within the rectangular slot on the left side of the right cross bar 31. After the second electromagnet 39 within the rectangular slot is energized, it generates a repulsive force on the insertion block 41, causing the insertion block 41 to overcome the elastic force of the second spring 40 and insert into the insertion slot 42 of the left cross bar 31, connecting multiple cross bars 31 together.

[0035] At the same time, the controller controls the second motor 25 to operate. The second motor 25 drives the left cross bar 31 to rotate. Since multiple cross bars 31 are already connected, under the drive of a single second motor 25, multiple winding wheels 29 rotate synchronously to release more wires 30, increasing the contact area between the wires 30 and the ground, thereby enhancing the grounding effect and more effectively eliminating the static electricity generated by the leatherette paper.

[0036] When the humidity sensor 23 detects that the environmental humidity is high, it indicates that the risk of static electricity generation is low. At this time, the controller does not need to control the second motor 25 to operate. At the same time, the second electromagnet 39 is de-energized, and the insertion block 41 withdraws from the insertion slot 42 under the action of the second spring 40, and each cross bar 31 returns to an independent state. All the wires 30 are wound around the winding wheels 29, keeping the entire static elimination device clean.

[0037] It is worth mentioning that during the processing, when the air humidity increases, it will cause the electrical signal generated by the humidity sensor 23 to change, so that the second electromagnet 39 is de-energized sequentially from right to left. Under the action of the torsion spring 32, the released wires 30 can be wound around the winding wheels 29 again.

[0038] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
