Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a material changing mechanism for efficiently changing materials. Background Art

[0002] Multi-station rotary die-cutting machine, also known as rotary machine, is commonly known as circular knife machine, hob machine or circular knife die-cutting machine. It continuously rotates and cuts in the form of a hob, and is one of the most efficient equipment among die-cutting machines. The die-cut products are widely used in mobile phones, computers, LCD monitors, digital cameras, LCD backlights and other fields.

[0003] In the prior art, after the circular knife die-cutter has finished unloading the material, the production line or equipment needs to be shut down before the material can be replaced. During the equipment shutdown period, the work stoppage will occur, and the production demand cannot be guaranteed. Especially for large production workshops, once the die-cutter stops, it is easy to cause the entire production line to collapse. Although various die-cutters that can be replaced without stopping are currently available on the market, such as the automatic material changing device for the circular knife die-cutter disclosed in the authorization announcement number CN104960026B, the adsorption roller adsorbs the end of the stand-by coil, and the push roller pushes the coil that is about to be used to the adsorption roller and generates a pressing force, so that the two coils with adhesive surfaces at the ends are bonded. It uses adhesive glue coated on the ends of the materials, and then when changing the materials In the process, the adhesive is used to achieve bonding. However, in actual use, since the materials are mostly in rolls and are generally purchased directly from suppliers, it is not practical to apply adhesive on the ends thereof. Moreover, it is easy for the adhesive to adhere to the material strip during use, that is, when the material is not changed, it will also affect the quality of the material strip. In the prior art, when a circular knife die-cutting machine splices new materials and old materials, it is necessary to cut the starting end of the new material and overlap and splice it with the end of the old material. There are at least two splicing sections after splicing, and the overlapping sections reduce the utilization rate of the material. The waste generated by cutting the new material is also easy to adhere to the spliced ​​material, which is easy to affect the subsequent production. Summary of the invention

[0004] The purpose of the present invention is to provide a material changing mechanism for efficiently changing materials, which can change the material belt without stopping the machine, avoiding the shutdown caused by changing the material belt and improving efficiency.

[0065] The splicing rubber roller module 40 is provided with a second tape area. The splicing rubber roller module 40 is assembled at the lower end of the first adsorption cavity 22. The splicing rubber roller module 40 is provided with, and the splicing rubber roller module 40 can move synchronously with the first module 20 in the horizontal direction;

[0066] The floating rubber roller module 50, as Figure 10 shown, the floating rubber roller module 50 includes a stop block 51, a first base 52, an elastic element 53 and a first rubber roller 54. The stop block 51 is fixed on the bottom plate 10. The first base 52 is slidably connected to one side of the bottom plate 10 through a slide rail group. The elastic element 53 is assembled between the stop block 51 and the first base 52. The first rubber roller 54 is rotatably connected to one side of the first base 52;

[0067] The electric rubber roller module 60, as Figure 11 shown, the electric guide rail 61 is assembled on the bottom plate 10. The second base 62 is slidably connected to one side of the electric guide rail 61. The second rubber roller 63 is rotatably connected to one side of the second base 62;

[0068] Among them, after the first strip is attached to the first air suction plate 24, the air inside the first adsorption cavity 22 and the second adsorption cavity 23 is extracted, which can form a negative pressure space inside the first adsorption cavity 22 and the second adsorption cavity 23. The first strip can be adsorbed through the first adsorption cavity 22 and the second adsorption cavity 23. After the second strip is attached to the second air suction plate 34, the air inside the third adsorption cavity 32 and the fourth adsorption cavity 33 is extracted, which can also form a negative pressure space inside the third adsorption cavity 32 and the fourth adsorption cavity 33. The second strip can be adsorbed through the third adsorption cavity 32 and the fourth adsorption cavity 33;

[0069] Further, the first material roll is wound by a first material tape, and the second material roll is wound by a second material tape.

[0070] When in use, taking the first material tape as the old roll material, and the old roll material is assembled on the air shaft 11 at the upper end of the first module 20, and the second material tape as the new roll material, and the new roll material is assembled on the air shaft 11 at the upper end of the second module 30 as an example. Of course, the above left and right are only for better describing the working process of the present application and do not represent specific limitations on the modules of the present application.

[0071] In this embodiment, when the remaining amount of the first material tape at the upper end of the first module 20 is small and needs to be replaced with the second material tape, tapes are placed in the first tape area and the second tape area respectively. The second material tape is assembled outside the air shaft 11 at the upper end of the second module 30. The reduction motor 15 adapted to the air shaft 11 is started, and the air shaft 11 at the upper end of the second module 30 is driven to rotate by the reduction motor 15, so as to feed the second material tape until the starting end of the second material tape moves to the middle of the second mold base 31. A negative pressure space is formed inside the third adsorption cavity 32 through the air pump module, and the starting end of the second material tape is adsorbed by the third adsorption cavity 32. The driving part 12 is started to make the first mold base 21 and the second mold base 31 approach each other, and the first material tape and the second material tape are clamped by the first mold base 21 and the second mold base 31. A negative pressure space is formed inside the first adsorption cavity 22 and the second adsorption cavity 23 through the air pump module, so that the first adsorption cavity 22 and the second adsorption cavity 23 adsorb the first material tape. The cutting element 25 is slid, and the first material tape is cut by the cutting element 25, so that the first material tape is divided into a front end and a tail end. At this time, the front end of the first material tape is separated from the air shaft 11, and the tail end of the first material tape is still assembled on the corresponding air shaft 11, and the starting end of the second material tape and the front end of the first material tape are connected end to end. After cutting, the cutting element 25 is reset, and the second module 30 is operated to bond the tape in the first tape area to the side close to the second module 30 at the cutting position, so as to splice the second material tape and the front end of the first material tape. After splicing, the negative pressure space states inside the first adsorption cavity 22, the second adsorption cavity 23 and the third adsorption cavity 32 are released, so that the first adsorption cavity 22, the second adsorption cavity 23 and the third adsorption cavity 32 no longer adsorb the first material tape and the second material tape;

[0072] Restart the driving unit 12 to move the first die carrier 21 and the second die carrier 31 away from each other. Start the reduction motor 15 adapted to the first strip, and wind up the end of the first strip. At the same time, convey the spliced strip. Start the splicing rubber roller module 40 to make the splicing rubber roller module 40 and the spliced strip run synchronously. When the splicing point of the strip gradually approaches the splicing rubber roller module 40, the splicing rubber roller module 40 bonds the tape in the second tape area to one side of the splicing point close to the splicing rubber roller module 40, thereby realizing non-stop material change, avoiding shutdown and production stoppage and reduction of production efficiency caused by material change. It should be noted that for more convenient expression, in this embodiment, the splicing point and the cutting point both refer to the joint of the starting end of the second strip and the front end of the first strip.

[0073] Please refer to the appendix Figures 4 to 6 As shown, the first module 20 further includes a slide rail assembly 26, two flange plates 27 and a first baffle 28. The slide rail assembly 26 is assembled inside the first die carrier 21. A slider is slidably arranged on the slide rail assembly 26. The cutting element 25 is fixedly connected to the slider, and the slider is connected to the air pump module. Both flange plates 27 are fixed to the lower end of the first die carrier 21. The flange plate 27 is connected to the splicing rubber roller module 40. The first baffle 28 is fixed to one end of the first die carrier 21. An avoidance groove is formed inside the first baffle 28, and one end of the cutting element 25 penetrates through the avoidance groove.

[0074] In this embodiment, after the first die carrier 21 and the second die carrier 31 are fitted, the first strip is adsorbed through the first adsorption cavity 22 and the second adsorption cavity 23. The air pump module is started to drive the slider, and due to the fixed connection between the slider and the cutting element 25, the first strip is cut by the cutting element 25, and then the first strip and the second strip are spliced with tape, thereby realizing non-stop material change.

[0075] Please refer to the appendix Figures 7 to 9As shown in the figure, the second module 30 further includes two bidirectional motors 35, two sliding blocks 36, a commutation motor 37, and a square shaft 38. The two bidirectional motors 35 are fixed to one end of the second mold base 31 away from the first mold base 21. The two sliding blocks 36 are respectively threadedly connected to the output ends of the two bidirectional motors 35, and the sliding blocks 36 are slidably connected to the second mold base 31. The commutation motor 37 and the square shaft 38 are assembled between the two sliding blocks 36. Among them, one sliding block 36 is fixedly connected to the commutation motor 37, and the other sliding block 36 is rotatably connected to the square shaft 38, and the square shaft 38 is fixedly connected to the output end of the commutation motor 37. The vertical cross-section of the square shaft 38 is rectangular. A plurality of fifth adsorption cavities are provided on the outer side of the square shaft 38. Third air path connectors are arranged inside the plurality of fifth adsorption cavities, and the third air path connectors are also connected to the air pump module through pipelines.

A plurality of air holes are evenly provided inside the tape suction plates 39, and the plurality of tape suction plates 39 correspond to the plurality of fifth adsorption cavities one by one. A tool clearance groove is provided on the tape suction plate 39, and the tool clearance groove is adapted to the cutting element 25.

[0076] Here, T-shaped flanges and T-shaped slide rails are fixed to both sides inside the second mold base 31. The bidirectional motor 35 and the T-shaped flange are fixedly connected by screws, the bidirectional motor 35 and the second mold base 31 are fixedly connected by the T-shaped flange, and the sliding block 36 is slidably connected to the outside of the T-shaped slide rail. The sliding block 36 and the second mold base 31 are slidably connected by the T-shaped slide rail.

[0077] Further, when the output end of the commutation motor 37 drives the square shaft 38 to rotate, the outer wall of the square shaft 38 does not contact the inner wall of the second mold base 31.

[0078] It should be noted that in the initial state, in the vertical direction, the tape suction plate 39 closest to the first mold base 21 and the second suction plate 34 are located in the same vertical plane. When the starting end of the second strip is pulled, the stopping position of the starting end of the second strip can be conveniently confirmed through the tool clearance groove on the tape suction plate 39.

[0079] In this embodiment, the tape is placed on the first tape area located at the top of the square shaft 38, and the tape is adsorbed by the fifth adsorption cavity located at the top of the square shaft 38. The second strip is assembled on the air shaft 11 and conveyed, so that the starting end of the second strip fits with the upper end of the relief groove. The air pump module is started to form a negative pressure space inside the first adsorption cavity 22, the second adsorption cavity 23 and the third adsorption cavity 32. The first strip is adsorbed by the first adsorption cavity 22 and the second adsorption cavity 23, and the second strip is adsorbed by the third adsorption cavity 32. The driving part 12 is started to make the first die holder 21 and the second die holder 31 fit together and clamp the first strip and the second strip. The slider inside the first die holder 21 is started, and the cutting element 25 is driven by the slider to cut the first strip, and the first strip is cut into a front end and a tail end. The bidirectional motor 35 is started. Since the slider 36 is threadedly connected to the output end of the bidirectional motor 35, the bidirectional motor 35 drives the slider 36 to move. Since the reversing motor 37 and the square shaft 38 are assembled between the two sliders 36, the slider 36 drives the reversing motor 37 and the square shaft 38 to move away from the second strip. After the square shaft 38 moves into the second die holder 31, the reversing motor 37 is started, and the square shaft 38 and the tape at the top of the square shaft 38 are driven to rotate by the reversing motor 37, so that the tape rotates from the top of the square shaft 38 to the end close to the second strip (in this embodiment, the rotation angle of the square shaft 38 and the tape at its top is 90 degrees). The bidirectional motor 35 is started again, and the square shaft 38 and the tape at its end are driven by the bidirectional motor 35 to move towards the second strip. When the tape contacts the second strip, the second strip and the front end of the first strip are spliced by the tape. At this time, the tape is adhered to the side of the first strip and the second strip close to the second module 30. At the same time, the adsorption of the fifth adsorption on the tape is released.

[0080] The splicing rubber roller module 40 includes a suction roller 41 and a driving motor 42. The suction roller 41 is rotatably connected between two flange plates 27. A sixth adsorption cavity is formed inside the suction roller 41. A fourth air passage joint is fixed inside the sixth adsorption cavity. The fourth air passage joint is connected to the air pump module through an air passage. A rubber bushing is sleeved outside the suction roller 41, and the second tape area is arranged on the rubber bushing. A plurality of air holes are evenly formed inside the rubber bushing, and the air holes are adapted to the sixth adsorption cavity. The driving motor 42 is fixed on one side of the first adsorption cavity 22, and the suction roller 41 is fixedly connected to the output end of the driving motor 42;

[0081] Here, a control terminal is also used in conjunction with the air pump module. A plurality of solenoid valves are arranged inside the air pump module. Through the control terminal, the opening and closing of the air pump module and the plurality of solenoid valves can be controlled respectively. After the air pump module operates, it can simultaneously extract the gas inside one or more of the first adsorption chamber 22, the second adsorption chamber 23, the third adsorption chamber 32, the fourth adsorption chamber 33, the fifth adsorption chamber, and the sixth adsorption chamber. One or more of the first adsorption chamber 22, the second adsorption chamber 23, the third adsorption chamber 32, the fourth adsorption chamber 33, the fifth adsorption chamber, and the sixth adsorption chamber form a negative pressure space;

[0082] It should be noted that the solenoid valve is an existing mature technology. The solenoid valve is an industrial device controlled by electricity. It is a basic automation component used to control fluids and belongs to an actuator, not limited to hydraulic or pneumatic. It is used in industrial control systems to adjust parameters such as the direction, flow rate, speed, and others of the medium. The solenoid valve can cooperate with different circuits to achieve the expected control, and both the control accuracy and flexibility can be guaranteed. There are many types of solenoid valves, and different solenoid valves play roles in different positions of the control system. The most commonly used ones are check valves, safety valves, direction control valves, speed regulating valves, etc. In this embodiment, as long as the air circuits inside the first adsorption chamber 22, the second adsorption chamber 23, the third adsorption chamber 32, the fourth adsorption chamber 33, the fifth adsorption chamber, and the sixth adsorption chamber can be controlled separately, no specific limitation is made.

[0083] In this embodiment, the tape is placed on the second tape area, and the tape is adsorbed through the sixth adsorption chamber. When the cutting element 25 finishes cutting the first strip of material, and the tape in the first tape area splices the first strip of material and the second strip of material, the negative pressure space states of the first mold frame 21, the first adsorption chamber 22, the second mold frame 31, and the fifth adsorption chamber are released, and the adsorption of the first strip of material, the second strip of material, and the tape located in the first tape area is released. The driving part 12 is started to move the first mold frame 21 and the second mold frame 31 away from each other to convey the spliced strip of material. At the same time, the reduction motor 15 adapted to the first strip of material is started, and the tail end of the first strip of material is wound up through the reduction motor 15. The driving motor 42 is started. Since the output ends of the air suction roller 41 and the driving motor 42 are fixedly connected, the driving motor 42 drives the air suction roller 41 and the above-mentioned tape to operate. When the splicing part of the spliced strip of material gradually approaches the air suction roller 41, the tape in the second tape area gradually adheres to the spliced strip of material. As the strip of material is conveyed, the tape in the second tape area is adhered to one side of the splicing part close to the splicing rubber roller module 40, and under the elastic action of the elastic element 53, the first rubber roller 54 and the air suction roller 41 are closely attached. Through the extrusion of the first rubber roller 54 and the air suction roller 41, the tape and the spliced strip of material are closely attached, improving the stability of the splicing part.
