Description

Technical Field

[0001] This utility model relates to the field of cutting and forming technology, and in particular to a sheet material cutting and forming mechanism. Background Technology

[0002] In product manufacturing, raw materials often need to be cut into the required shapes to form sheets. For example, in badge production, reflective paper or stickers need to be cut into sheets, which are then assembled or glued together with the cover to produce the finished badge.

[0003] In existing patents, Chinese patent application number 202023011419.7 discloses a mask sticker cutting and forming device, including a frame and a cutting component. The frame includes an operating table fixedly mounted on a support frame, with raw material paper rolls and waste paper rolls distributed at both ends of the operating table. An installation groove is provided at one end of the operating table, and the cutting component is positioned on the operating table corresponding to the installation groove. The free end of the mask sticker strip from the raw material paper roll passes through the cutting component and is wound onto the waste paper roll. A transmission component is provided on the support frame, and a prying component is provided on the transmission component corresponding to the cutting component. This patent document describes a method where the cut and formed sheet material falls downwards onto the transmission component via the cutting component and is output through the transmission component. Only after the transmission component delivers the cut and formed sheet material to a preset position can it be picked up by an external robotic arm, which delays the picking time and reduces the efficiency of the external robotic arm. Therefore, the shortcomings are obvious, and a solution is urgently needed. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a sheet material cutting and forming mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sheet material cutting and forming mechanism includes a raw material feeding device and a cutting and forming device disposed on the discharge side of the raw material feeding device. The cutting and forming device includes a cutting seat located on the discharge side of the raw material feeding device, an inner blade head that is lifted and disposed on the top surface of the cutting seat, an outer blade assembly disposed on the top surface of the cutting seat, and a lifting cutting driver disposed on the cutting seat. The outer blade assembly is provided with a feed groove in the transverse direction, and a cutting inner hole that penetrates the feed groove is longitudinally opened in the middle of the outer blade assembly. The inner blade head is adapted to the cutting inner hole. The lifting cutting driver is used to drive the inner blade head to move up and down in the cutting inner hole. The cutting edge of the inner blade head cooperates with the cutting edge of the cutting inner hole. The raw material feeding device is used to supply raw materials into the feed groove.

[0007] Furthermore, the lifting and cutting driver includes a cutting cylinder mounted on the cutting seat, and the piston rod of the cutting cylinder is driven and connected to the inner cutter head.

[0008] Furthermore, the lifting and cutting driver also includes a guide rod mounted on the bottom surface of the inner blade head, an abutment plate disposed at the bottom end of the guide rod, and a reset elastic element elastically connected to the cutting seat and the abutment plate; the piston rod of the cutting cylinder abuts against the bottom surface of the abutment plate, and the bottom surface of the inner blade head can abut against the top surface of the cutting seat.

[0009] Furthermore, the outer blade assembly includes an inner blade guide plate mounted on the top surface of the cutting seat, an outer blade ring mounted on the top surface of the inner blade guide plate, and a pad sandwiched between the inner blade guide plate and the outer blade ring. The inner blade guide plate has a central hole in the middle, which is coaxially arranged with the blade hole of the outer blade ring to form a cutting inner hole. The inner blade guide plate, the pad, and the outer blade ring form a material passage groove, and the cutting edge of the inner blade head is engaged with the cutting hole of the outer blade ring for cutting.

[0010] Furthermore, the inner blade guide plate and the outer blade ring are positioned and assembled by several positioning pins. The positioning pins have locking holes in their axial direction, and locking fasteners are detachably connected to the locking holes. The locking fasteners pass through the locking holes and are detachably connected to the cutting seat.

[0011] Furthermore, the sheet material cutting and forming mechanism also includes a waste material guide installed on the side of the cutting seat away from the raw material supply device. The inlet of the waste material guide is used to connect with the outlet of the feed trough. A roller is rotatably connected to the inlet of the waste material guide.

[0012] Furthermore, the raw material supply device includes a roller conveying module disposed on one side of the cutting seat and located at the inlet end of the feed trough, and a raw material supply module disposed on the feed side of the roller conveying module. The raw material supply module is used to supply raw materials to the roller conveying module, and the roller conveying module is used to transport the raw materials into the feed trough.

[0013] Furthermore, the raw material supply module includes a base connected to the cutting seat, a hopper detachably connected to the base for storing raw materials, and a picking robot movably disposed above the hopper for picking up the raw materials stored in the hopper to the roller conveyor module.

[0014] Furthermore, the raw material supply module includes a base connected to the cutting seat and an unwinding frame mounted on the base. The unwinding frame is used to install raw material rolls, which can rotate relative to the unwinding frame to supply raw materials to the roller conveying module.

[0016] The beneficial effects of this utility model are as follows: In practical applications, the raw material supply device supplies raw materials to the cutting and forming device, allowing the raw materials to pass through the inner cutting hole along the feed groove. The inner wall of the feed groove limits the two sides of the raw materials, which not only improves the stability of the raw material movement but also enhances the stability and quality during cutting. At this time, the lifting cutting driver drives the inner blade head to move upward along the inner cutting hole, so that the blade edge of the inner blade head engages with the blade edge of the inner cutting hole to cut the raw material. As the inner blade head moves upward, the sheet material cut from the raw material rises to the waiting position for the external robot to pick up the sheet material. After the sheet material on the inner blade head at the high position is removed, the lifting cutting driver drives the inner blade head to descend and reset, and the raw material supply device supplies raw materials to the cutting and forming device again, allowing the raw material to move a preset displacement along the feed groove to facilitate the cutting and forming of the next sheet material. Specifically, during the cutting process, the raw material supply device provides a certain tension to the raw material, ensuring that the raw material always enters the feed groove straight. This invention has a simple structure and low cost. It can quickly cut and shape sheet materials and output the cut and shaped sheet materials upward (cutting and shaping method from bottom to top) so that external robotic arms can quickly pick up the sheet materials. It is beneficial for application in automated production lines and automated equipment. Attached Figure Description

Detailed Implementation

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0027] Example 1.

[0028] like Figure 1 and Figures 3 to 7 As shown, this utility model provides a sheet material cutting and forming mechanism, which includes a raw material feeding device 1 and a cutting and forming device 2 disposed on the discharge side of the raw material feeding device 1. The cutting and forming device 2 includes a cutting seat 3 located on the discharge side of the raw material feeding device 1, an inner blade 4 that is lifted and disposed on the top surface of the cutting seat 3, an outer blade assembly 5 disposed on the top surface of the cutting seat 3, and a lifting cutting driver 6 disposed on the cutting seat 3. The outer blade assembly 5 is provided with a feed groove 7 in the transverse direction, and a cutting inner hole 8 that penetrates the feed groove 7 is longitudinally opened in the middle of the outer blade assembly 5. The inner blade 4 is adapted to the cutting inner hole 8. The lifting cutting driver 6 is used to drive the inner blade 4 to move up and down within the cutting inner hole 8. The cutting edge of the inner blade 4 cooperates with the cutting edge of the cutting inner hole 8. The raw material feeding device 1 is used to supply raw material 44 into the feed groove 7. In this embodiment, the raw material 44 can be paper tape, paper sheet, film tape, or film sheet, etc.

[0029] In practical applications, the raw material supply device 1 supplies raw material 44 to the cutting and forming device 2, allowing raw material 44 to pass through the cutting inner hole 8 along the material passage 7. The inner wall of the material passage 7 limits the two sides of the raw material 44, which not only improves the stability of the movement of raw material 44, but also improves the stability and quality during cutting. At this time, the lifting cutting driver 6 drives the inner blade 4 to move upward along the cutting inner hole 8, so that the blade of the inner blade 4 cooperates with the blade of the cutting inner hole 8 to cut the raw material 44. As the inner blade 4 moves upward, the sheet material cut from the raw material 44 will rise to the waiting position for the external robot to pick up the sheet material. When the sheet material on the inner blade 4 at the high position is picked up, the lifting cutting driver 6 drives the inner blade 4 to descend and reset, and the raw material supply device 1 supplies raw material 44 to the cutting and forming device 2 again, so that raw material 44 moves a preset displacement along the material passage 7 to facilitate cutting and forming the next sheet material. Specifically, during the cutting process, the raw material supply device 1 provides a certain tension to the raw material 44, ensuring that the raw material 44 always enters the feed trough 7 in a straight line. This utility model has a simple structure, low cost, and can quickly cut and form sheet materials, and output the cut sheet materials upwards (cutting and forming method from bottom to top), so that external robotic arms can quickly pick up the sheet materials, which is beneficial for application in automated production lines and automated equipment.

[0030] Specifically, the shape of the inner blade 4 and the shape of the cutting inner hole 8 can be changed or modified according to the shape of the sheet material to be cut, such as square, round, etc.

[0031] In this embodiment, the lifting and cutting driver 6 includes a cutting cylinder 9 mounted on the cutting seat 3, and the piston rod of the cutting cylinder 9 is drivenly connected to the inner cutter head 4. In practical applications, the inner cutter head 4 is driven to move up and down by extending and retracting the piston rod of the cutting cylinder 9, so as to cut the raw material 44.

[0032] In this embodiment, the lifting and cutting driver 6 also includes a guide rod 10 installed on the bottom surface of the inner cutter head 4, an abutment plate 11 disposed at the bottom end of the guide rod 10, and a reset elastic member 12 elastically connected to the cutting seat 3 and the abutment plate 11; the piston rod of the cutting cylinder 9 abuts against the bottom surface of the abutment plate 11, and the bottom surface of the inner cutter head 4 can abut against the top surface of the cutting seat 3.

[0033] In practical applications, the piston rod of the cutting cylinder 9 extends and pushes the abutment plate 11 upward, causing the abutment plate 11 to drive the guide rod 10 and the inner cutter head 4 to move upward and compress the reset elastic element 12. The upward-moving inner cutter head 4 cuts the raw material 44 to form a sheet. When the sheet on the inner cutter head 4 is removed, the piston rod of the cutting cylinder 9 retracts, and the piston rod of the cutting cylinder 9 releases the upward pushing force on the abutment plate 11. The abutment plate 11 moves downward and resets under the action of the rebound force of the reset elastic element 12. The downward-reset abutment plate 11 drives the guide rod 10 and the inner cutter head 4 to move downward and reset until the bottom surface of the inner cutter head 4 contacts the top surface of the cutting seat 3.

[0034] In addition, the piston rod of the cutting cylinder 9 and the contact plate 11 are not fixedly connected, which facilitates disassembly and maintenance.

[0035] Specifically, the reset elastic element 12 is a reset spring, which is sleeved outside the guide rod 10. The guide rod 10 guides and positions the reset spring, improving the working stability of the reset spring and facilitating its assembly and disassembly.

[0036] In this embodiment, a mounting plate 13 is provided on the top surface of the cutting seat 3, the outer blade assembly 5 is mounted on the top surface of the mounting plate 13, the inner blade head 4 is located above the mounting plate 13, a guide hole 14 is provided in the middle of the mounting plate 13, the guide rod 10 slides through the guide hole 14, the abutment plate 11 is located below the mounting plate 13, and the two ends of the reset elastic member 12 abut against the bottom surface of the mounting plate 13 and the top surface of the abutment plate 11, respectively. With this structural design, during the lifting and lowering of the inner blade head 4, the guide rod 10 slides along the guide hole 14, guiding and positioning the movement of the guide rod 10, thus improving the stability of the lifting and lowering of the inner blade head 4.

[0037] In this embodiment, the outer blade assembly 5 includes an inner blade guide plate 15 mounted on the top surface of the cutting base 3, an outer blade ring 16 mounted on the top surface of the inner blade guide plate 15, and a pad 17 sandwiched between the inner blade guide plate 15 and the outer blade ring 16. A central hole is formed in the middle of the inner blade guide plate 15, which is coaxially aligned with the blade hole of the outer blade ring 16 to form a cutting inner hole 8. A material passage groove 7 is formed between the inner blade guide plate 15, the pad 17, and the outer blade ring 16. The cutting edge of the inner blade head 4 engages with the blade hole of the outer blade ring 16 for cutting. This structural design enables modular assembly of the outer blade assembly 5, facilitating disassembly, assembly, and maintenance. Furthermore, depending on the thickness of the different raw materials 44 to be cut, only the number of pads 17 needs to be increased or decreased, or pads 17 of different thicknesses need to be replaced.

[0038] In this embodiment, the inner blade guide plate 15 and the outer blade ring 16 are positioned and assembled via a plurality of positioning pins 18. The positioning pins 18 pass through the outer blade ring 16, the pad 17, and the inner blade guide plate 15. The positioning pins 18 have axially formed locking holes, and the locking fasteners 19 pass through the locking holes and are detachably connected to the cutting seat 3. Specifically, there are four positioning pins 18 arranged in a rectangular shape. The locking fasteners 19 are locking bolts, and the studs of the locking bolts are threadedly connected to the cutting seat 3 to lock the outer blade ring 16, the pad 17, and the inner blade guide plate 15 onto the cutting seat 3. This structural design ensures the positional accuracy and stability of the inner blade guide plate 15 and the outer blade ring 16 during assembly, thereby guaranteeing the cutting accuracy. It also facilitates the replacement of inner blade guide plates 15 and outer blade rings 16 of different specifications. Furthermore, the stud of the locking fastener 19 passes through the locking hole of the positioning pin 18 and is threadedly connected to the cutting seat 3. This not only ensures a firm connection between the outer blade ring 16, the inner blade guide plate 15, the pad 17, and the cutting seat 3, but also results in a simple structure, an aesthetically pleasing appearance, and a reduction in the number of holes to be machined in the outer blade ring 16 and the inner blade guide plate 15.

[0039] In this embodiment, the sheet material cutting and forming mechanism also includes a waste material discharge member 20 installed on the side of the cutting seat 3 away from the raw material supply device 1. The inlet of the waste material discharge member 20 is used to connect with the outlet of the material conveying groove 7. A roller 21 is rotatably connected to the inlet of the waste material discharge member 20. In practical applications, waste material is generated after the raw material 44 is cut into sheets. As the raw material 44 moves, the waste material will pass around the roller 21 and enter the waste material discharge member 20, which will discharge the waste material. The roller 21 can rotate relative to the waste material discharge member 20. The rotating roller 21 rolls against the waste material, reducing the frictional resistance of the waste material movement, so that the waste material can move smoothly along the waste material discharge member 20 and is less likely to jam.

[0040] Specifically, a cutter is installed inside the waste discharge part 20. The cutter can be a pneumatic shear, used to cut the waste inside the waste discharge part 20. In practical applications, when the waste inside the waste discharge part 20 or the waste output by the waste discharge part 20 is too long, the cutter cuts the waste to a fixed length to avoid obstructing the movement of the waste due to excessive length, and also to facilitate the fixed-length recycling of the waste.

[0041] In this embodiment, the raw material supply device 1 includes a roller conveying module 22 disposed on one side of the cutting seat 3 and located at the inlet end of the feed trough 7, and a raw material supply module 23 disposed on the feed side of the roller conveying module 22. The raw material supply module 23 is used to supply raw material 44 to the roller conveying module 22, and the roller conveying module 22 is used to transport the raw material 44 into the feed trough 7.

[0042] In practical applications, the raw material supply module 23 supplies the raw material 44 to the roller conveying gap of the roller conveying module 22. The roller conveying module 22 conveys the raw material 44, causing it to move into the feed trough 7 and move along the feed trough 7, thereby realizing the automated feeding of the raw material 44. The roller conveying module 22 conveys the raw material 44 intermittently to achieve fixed-length conveying of the raw material 44 and to ensure that the raw material 44 has a certain tension, so that the raw material 44 can enter the feed trough 7 straight.

[0043] In this embodiment, the raw material supply module 23 includes a base 24 connected to the cutting seat 3, a hopper 25 detachably connected to the base 24 for storing raw materials 44, and a picking robot 26 movably disposed above the hopper 25 for picking up the raw materials 44 stored in the hopper 25 to the roller conveying module 22.

[0044] In practical applications, raw material sheets of a fixed length are stacked in the hopper 25. After the picking robot 26 picks up the top layer of raw material sheet in the hopper 25, it conveys the raw material sheet to the roller conveying gap of the roller conveying module 22, so that the roller conveying module 22 can convey the raw material sheet to realize the automated feeding of raw material sheet.

[0045] Specifically, the side wall of the hopper 25 is hollow, which makes it easy for operators to observe the quantity of raw material sheets in the hopper 25, and also makes it easy for operators to add raw material sheets into the hopper 25 and for the picking robot arm 26 to reach into the hopper 25 to pick up raw material sheets.

[0046] Specifically, the top end of the hopper 25 is provided with a handle 27, which facilitates lifting the hopper 25 and thus allows for the assembly and disassembly of the hopper 25 from the base 24.

[0047] Specifically, the bottom surface of the hopper 25 is provided with positioning holes 28 and / or positioning posts. Correspondingly, the base 24 is provided with positioning posts and / or positioning holes 28. The positioning posts of the base 24 and the positioning holes 28 of the hopper 25 are in concave-convex fit, and the positioning holes 28 of the base 24 and the positioning posts of the hopper 25 are adapted to each other. During the assembly of the hopper 25 and the base 24, the positioning holes 28 and the positioning posts are in fit, which improves the positional accuracy and stability of the assembly of the hopper 25 and the base 24, thereby improving the positional accuracy of the raw material sheets in the hopper 25, which is beneficial for the picking robot 26 to accurately pick up the raw material sheets in the hopper 25.

[0048] Specifically, the picking robot 26 includes a translation driver 29 mounted on the base 24, a lifting picking driver 30 mounted on the moving end of the translation driver 29, a vacuum suction plate 31 mounted on the lifting end of the lifting picking driver 30, and a vacuum degree detector or pressure switch mounted on the top or side of the vacuum suction plate 31. The vacuum degree detector or pressure switch is used to determine whether the vacuum suction plate 31 picks up the raw material 44. Preferably, the translation driver 29 can be a cylinder or the like, and the lifting picking driver 30 can be a motor screw module or the like.

[0049] In practical applications, when the vacuum suction plate 31 picks up the raw material sheet in the hopper 25, the lifting and picking driver 30 drives the vacuum suction plate 31 to descend until the vacuum suction plate 31 contacts and sucks up the top layer of raw material sheet. During this process, the vacuum degree detector or pressure switch monitors the air pressure in real time. When the vacuum degree detector or pressure switch detects a change in the vacuum degree of the vacuum suction plate 31, it proves that the vacuum suction plate 31 has picked up the raw material sheet. At this time, the lifting and picking driver 30 drives the vacuum suction plate 31 and the raw material sheet to move upward to a preset height. Then, the translation driver 29 drives the lifting and picking driver 30, along with the vacuum suction plate 31 and the raw material sheet, to move closer to the roller conveying gap of the roller conveying module 22, so that the roller conveying module 22 can convey the raw material sheet. Furthermore, when the lifting pickup driver 30 drives the vacuum suction plate 31 to its lowest position, and the vacuum level detector or pressure switch detects no change in the vacuum level of the vacuum suction plate 31, it indicates that the vacuum suction plate 31 has not picked up any raw material sheet. At this time, the vacuum level detector or pressure switch will send a signal to the machine's control system, causing the control system to issue an alarm to remind the operator to check the machine or add raw material sheet to the hopper 25. The vacuum level detector or pressure switch not only monitors the vacuum level of the vacuum suction plate 31 to determine whether it has picked up any raw material sheet, but also controls the downward position of the vacuum suction plate 31 driven by the lifting pickup driver 30 based on whether it has picked up any raw material sheet.

[0050] Specifically, a positioning block 32 is rotatably connected to the end of the base 24 away from the cutting seat 3. The positioning block 32 is in an upright state under its own weight. The upright positioning block 32 is used to position the outer side of the hopper 25.

[0051] In this embodiment, the roller conveying module 22 includes a support 33 connected to one side of the cutting seat 3, a guide plate 34 mounted on the top surface of the support 33, a lower conveying roller 35 rotatably connected to the support 33 and located between the inlet end of the feed chute 7 and the guide plate 34, a guide frame 36 mounted on the support 33 and mounted above the guide plate 34 and the lower conveying roller 35, a lifting plate 37 slidably connected to the guide frame 36, an upper conveying roller 38 rotatably connected to the lifting plate 37 and located above the lower conveying roller 35, a lifting conveying driver 39 mounted on the top of the guide frame 36 for driving the lifting plate 37 to rise and fall, and a rotation drive module 40 mounted on the support 33 for driving the lower conveying roller 35 to rotate.

[0052] In practical applications, the picking robot 26 first places one end of the raw material 44 on the guide plate 34, and then drives the raw material 44 to move along the guide plate 34 into the conveying gap between the upper conveying roller 38 and the lower conveying roller 35. The output end of the lifting conveying driver 39 extends and drives the lifting plate 37, along with the upper conveying roller 38, to descend until the upper conveying roller 38 and the lower conveying roller 35 clamp the raw material 44. The rotation drive module 40 drives the lower conveying roller 35 to rotate. The rotating lower conveying roller 35 cooperates with the upper conveying roller 38 to drive the raw material 44 to move, thereby realizing the conveying of the raw material 44. During the process of the lifting conveying driver 39 driving the lifting plate 37 to rise and fall, the guide frame 36 plays a guiding and positioning role for the lifting plate 37, improving the lifting stability of the lifting plate 37. In addition, the lifting conveyor driver 39 drives the lifting plate 37 to rise and fall, which can adjust the conveying gap between the upper conveying roller 38 and the lower conveying roller 35. This not only meets the needs of conveying raw materials 44 of different thicknesses, but also facilitates the passage of raw materials 44 through the conveying gap between the upper conveying roller 38 and the lower conveying roller 35 (facilitating material passage).

[0053] Specifically, both the lower conveyor roller 35 and the upper conveyor roller 38 are fitted with a gear 41. The gear 41 of the upper conveyor roller 38 is used to mesh with the gear 41 of the lower conveyor roller 35 for transmission. During the process of the upper conveyor roller 38 and the lower conveyor roller 35 cooperating to drive the movement of the raw material 44, the gear 41 of the upper conveyor roller 38 meshes with the gear 41 of the lower conveyor roller 35 to ensure that the upper conveyor roller 38 and the lower conveyor roller 35 can stably convey the raw material 44.

[0054] Specifically, the lifting and conveying driver 39 can be a cylinder, the rotation drive module 40 can be a motor, and a pressing elastic element 42 is provided between the top of the guide frame 36 and the lifting plate 37. The pressing elastic element 42 can be a pressing spring. The pressing spring is sleeved on the guide post of the guide frame 36, and the two ends of the pressing spring elastically abut against the top of the guide frame 36 and the top surface of the lifting plate 37, respectively.

[0055] In practical applications, under normal conditions, the downward-pressing elastic element 42 extends and applies a downward force to the lifting plate 37, causing the upper conveying roller 38 to stably press the raw material 44 onto the lower conveying roller 35. At this time, the output end of the lifting conveyor driver 39 extends and does not apply force to the lifting plate 37. The downward-pressing elastic element 42 can drive the lifting plate 37 to move downward and reset. The downward-pressing elastic element 42 also acts as a buffer, preventing hard impact collisions between the upper conveying roller 38 and the lower conveying roller 35. It can also adapt to the thickness error of the raw material 44, ensuring stable conveying of the raw material 44. When it is necessary to lift the upper conveying roller 38, the output end of the lifting conveyor driver 39 retracts and drives the lifting plate 37 to rise and compress the downward-pressing elastic element 42, thereby increasing the conveying gap between the upper conveying roller 38 and the lower conveying roller 35.

[0056] Example 2.

[0057] like Figure 1 As shown, the difference between this embodiment and embodiment one is that in this embodiment, the raw material supply module 23 includes a base 24 connected to the cutting seat 3 and an unwinding frame 43 installed on the base 24. The unwinding frame 43 is used to install the raw material 44 rolls. The raw material 44 rolls can rotate relative to the unwinding frame 43 to supply the raw material 44 to the roller conveying module 22.

[0058] In practical applications, the raw material roll 44 is rotatably mounted on the unwinding frame 43. The raw material strip 44 on the raw material roll 44 passes through the roller conveying gap of the roller conveying module 22, so that the roller conveying module 22 can convey the raw material strip 44.
