Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cutting and punching integrated machine, in particular to a plastic plate slitting and punching device. BACKGROUND

[0002] The above-mentioned plastic plate mainly refers to, but not absolutely limited to, refers to the degradable plastic plate. Taking the plastic plate with excellent degradable performance as an example, because it is processed from the degradable plastic particles made of starch and a little PLA (poly lactic acid), so the degradation rate can reach to be close to 100%. This plastic plate with excellent degradable performance is mainly used as various packaging materials, such as packaging of poultry eggs in the food category, household appliance parts in the light industry product category, etc., which can play a good role of positioning and buffering the packaged products, and is favored by people in the product logistics industry.

[0003] In the disclosed Chinese patent documents, there are some technical information related to the plastic plate slitting and punching device. Typically, CN106042049B recommends a "movable punching mechanism for plastic plate", which is driven by two moving motors to move the moving plate with the plastic plate to be punched, and then the punch is driven by the punching cylinder to punch holes on the plastic plate. The removed material falls from the through hole on the moving plate (see the specification of the patent for details, see paragraph 0020). However, the patent does not explain the nature of the plastic plate and the use after punching. In addition, the patent does not have the function of slitting the plastic plate. More typically, CN202742433U provides a "plastic plate punching and shearing integrated machine", which is used in the processing of plastic plate, and is composed of a traction device, a punching device, a shearing device and a product removal trolley arranged on a workbench. See the specification of the patent for details, see paragraph 0020.

[0004] The CN202742433U has the functions of shearing and punching, but it is not for the aforementioned degradable plastic plate used as a packaging material. For the degradable packaging material with specific use, there are specific requirements, such as the length of the slitting can be adjusted as needed, and as for the current machinery, it is difficult to produce a degradable plastic plate with a relatively large thickness, such as a thickness of 20 to 40 mm, as a packaging material (the degradable plastic plate with a large thickness is difficult to be foamed and molded after being extruded from the head of the extruder, and the product quality is difficult to guarantee). If a degradable plastic plate that meets the aforementioned thickness requirement of 20 to 40 mm or even more is to be produced, the existing machinery that can only produce a thin degradable plastic plate needs to be completely reformed, which is not suitable from an economic point of view, and there are many technical obstacles in the equipment reform. Moreover, the use of a degradable plastic plate with a large thickness is much less than that of a thin plastic plate. Therefore, it is of positive significance to explore technical measures to solve the aforementioned problems. The technical solution to be introduced below is generated in this background. SUMMARY

[0005] The task of the present application is to provide a plastic plate slitting and punching device that helps to meet the requirement of adjusting the length of the slitting as needed, facilitates the good stacking of ordinary thin plastic plates in the thickness direction to become thick plastic plates to meet the relatively strict requirement of the cushioning effect as a packaging material, facilitates the realization of the ideal punching efficiency and guarantees excellent punching effect, is beneficial to the good relay between cutting and stacking and punching to improve the processing efficiency.

[0031] See the key points Figure 1The preferred, but not absolutely limited, structure of the aforementioned plastic sheet cutting mechanism 1 is as follows: it includes a front sliding guide rail fixing column 11 for the cutting blade holder, a rear sliding guide rail fixing column 12 for the cutting blade holder, a cutting blade holder 13, a cutting blade 14, a cutting blade holder drive cylinder support beam 15, and a cutting blade holder drive cylinder 16. The lower rear end of the front sliding guide rail fixing column 11 is preferably fixed to the front side of the left end of the aforementioned upper front beam 105a of the frame by welding, while the upper end extends upwards. The front sliding guide rail fixing column 11 is secured longitudinally to the rearward side (facing the rearward side) by screws. A front sliding guide rail 111 of the cutting blade holder is fixed in place. A rear sliding guide rail fixing column 12 of the cutting blade holder corresponds to the aforementioned front sliding guide rail fixing column 11. The lower front end of the rear sliding guide rail fixing column 12 is preferably fixed to the rear side of the left end of the aforementioned upper rear beam 105b of the frame by welding, while the upper end extends upward. On the side of the rear sliding guide rail fixing column 12 facing the front sliding guide rail fixing column 11, i.e., the forward-facing side, a rear sliding guide rail 121 of the cutting blade holder, corresponding to the position of the front sliding guide rail 111, is fixed longitudinally by screws in front of the cutting blade holder 13. A front slider 131 of the cutting blade holder is fixed to the end with screws. The front slider 131 of the cutting blade holder 13 slides in cooperation with the front sliding guide rail 111 of the cutting blade holder. A rear slider 132 of the cutting blade holder 13 is fixed to the rear end with screws. The rear slider 132 of the cutting blade holder 13 slides in cooperation with the rear sliding guide rail 121 of the cutting blade holder. A cutting blade holder connecting rod 133 is fixed at the upper center position of the cutting blade holder 13. That is, the lower end of the cutting blade holder connecting rod 133 is fixed at the upper center position of the cutting blade holder 13. The cutting blade 14 is fixed to the cutting blade holder 13 by means of the cutting blade fixing plate 141 and the cutting blade fixing plate screw 1411. The cutting blade 14 is fixed at the middle of the lower right side, with its blade 142 facing downwards. The cutting blade holder drive cylinder support beam 15 is fixed between the tops of the front and rear sliding guide rail fixing columns 11 and 12 of the cutting blade holder using cutting blade drive cylinder support beam fixing screws 151. In this embodiment, the cutting blade holder drive cylinder 16 is a cylinder and is fixed at the middle of the side of the cutting blade holder drive cylinder support beam 15 facing upwards. The cutting blade holder drive cylinder column 161 of the cutting blade holder drive cylinder 16 faces downwards and extends to the lower part of the cutting blade holder drive cylinder support beam 15 before connecting to the upper end of the aforementioned cutting blade holder connecting rod 133.

[0032] When the aforementioned cutting blade holder drive cylinder 16 receives a working signal from the electrical controller, for example, requiring the cutting blade 14 to descend and cut the plastic sheet conveyed from the previous station, such as the foaming molding station, to the left plastic sheet conveying mechanism 2, then under the operation of the cutting blade holder drive cylinder 16, the cutting blade holder drive cylinder column 161 extends downward, i.e., out of the cylinder body. The cutting blade holder drive cylinder column 161, through the cutting blade holder connecting rod 133, moves the cutting blade holder 13 along with the cutting blade 14 downward, and the cutting blade blade 142 cuts the plastic sheet at the left end of the frame 10. During the downward movement of the aforementioned cutting blade holder 13, the front and rear slides 131 and 132 of the cutting blade holder slide downward along the front and rear slide guides 111 and 121 of the cutting blade holder, respectively. Since the upward movement of the cutting blade 14 is the opposite of the above (the cutting blade holder drive cylinder column 161 moves upward, i.e., into the cylinder body), the applicant will not elaborate further.

[0033] Please see Figure 2 and Figure 3 And continue to combine Figure 1The structure of the aforementioned right plastic sheet conveying mechanism 3 is the same as that of the aforementioned left plastic sheet conveying mechanism 2. Therefore, the applicant will only describe the left plastic sheet conveying mechanism 2 in detail below. The left plastic sheet conveying mechanism 2 includes a front support 21 for the left plastic sheet conveying roller, a rear support 22 for the left plastic sheet conveying roller, a drive motor 23 for the left plastic sheet conveying roller, a drive reduction gearbox 24 for the left plastic sheet conveying roller, and a set of left plastic sheet conveying rollers 25. The front support 21 for the left plastic sheet conveying roller is connected to the middle part of the front support 211 by screws 213, and each end of the front support 211 has an upwardly folded end guard ear 2111. The plastic sheet left conveyor roller front support bracket 211 is fixedly welded to the rear left end of the aforementioned upper front beam 105a of the frame. The plastic sheet left conveyor roller rear support bracket 22 corresponds to the plastic sheet left conveyor roller front support bracket 21, and the plastic sheet left conveyor roller rear support bracket 221 is fixed by plastic sheet left conveyor roller rear support bracket screws (not shown in the figure) and the middle part corresponding to its lower part, with each end forming an upwardly folded plastic sheet left conveyor roller rear support bracket fixing ear 2211. The plastic sheet left conveyor roller rear support bracket fixing bracket 221 is fixedly welded to the front left end of the aforementioned upper rear beam 105b of the frame. The plastic sheet left conveyor roller drive motor 23 is horizontally positioned. The state is connected to the left conveyor roller drive reduction gearbox 24 of the plastic sheet, and the left conveyor roller drive reduction gearbox 24, together with the left conveyor roller drive motor 23 of the plastic sheet, is fixed to the left conveyor roller drive reduction gearbox fixing seat 241 of the plastic sheet. The left conveyor roller drive reduction gearbox fixing seat 241 of the plastic sheet is fixed to the upward side of the aforementioned upper front beam 105a of the frame. The final stage power output shaft of the left conveyor roller drive reduction gearbox 24 of the plastic sheet faces rearward and is fixed with a left conveyor roller drive main gear 242 of the plastic sheet. A group of left conveyor rollers 25 of the plastic sheet are supported between the aforementioned left conveyor roller front and rear support seats 21 and 22 of the plastic sheet in a state of alternating rotation and non-rotation. The front end of the plastic sheet left conveyor roller 25's plastic sheet left conveyor roller shaft 251 extends to the front side of the aforementioned plastic sheet left conveyor roller front support 21, and each shaft is provided with a plastic sheet left conveyor roller gear 2511. The plastic sheet left conveyor roller gears 2511 on each pair of adjacent plastic sheet left conveyor roller shafts 251 mesh with each other. In the aforementioned set of plastic sheet left conveyor rollers 25, the front end and rear end of the rotating plastic sheet left conveyor roller's plastic sheet left conveyor roller shaft 251 are rotatably supported on the front and rear support seats 21 and 22 of the plastic sheet left conveyor roller through bearings, respectively. The plastic sheet left conveyor roller gear 2511 provided at the front end of the rotating plastic sheet left conveyor roller shaft 251 is fixed to the front end of the rotating plastic sheet left conveyor roller shaft 251.The left conveyor roller gear 2511, located at the front end of the non-rotating left conveyor roller shaft 251, is rotatably mounted at the front end of the left conveyor roller shaft 251 via a left conveyor roller gear rotating bearing 25111. The left conveyor roller gear 2511 below the aforementioned left conveyor roller drive main gear 242 meshes with the left conveyor roller drive main gear 242. A roller gap baffle 26 is provided above each pair of adjacent left conveyor roller gears 2511 along their length. The front end of the roller gap baffle 26 is fixed to the front mating cavity 212 of the roller gap baffle formed on the upper surface of the front support seat 21 of the left conveyor roller shaft 21 by a front roller gap baffle screw 261, and the rear end of the roller gap baffle 26 is fixed to the rear mating cavity 222 of the roller gap baffle formed on the upper surface of the rear support seat 22 of the left conveyor roller shaft 22 by a rear roller gap baffle screw 262.

[0034] Depend on Figure 3 As can be seen from the diagram and the above explanation, the reason why a set of plastic sheet left conveyor rollers 25 are arranged with one rotating and one non-rotating roller alternately is to ensure that the rotation direction (clockwise rotation) of the aforementioned plastic sheet left conveyor roller gear 2511 is consistent.

[0035] When the plastic sheet cut (i.e., "cutting", hereinafter the same) by the aforementioned plastic sheet cutting mechanism 1 is to be conveyed to the plastic sheet right conveying mechanism 3 via a set of left plastic sheet conveying rollers 25, under the operation of the left plastic sheet conveying roller drive motor 23 controlled by the electrical controller, the left plastic sheet conveying roller drive motor 23 drives the left plastic sheet conveying roller drive reduction gearbox 24, the final stage power output shaft of the left plastic sheet conveying roller drive reduction gearbox drives the left plastic sheet conveying roller drive main gear 242, and the left plastic sheet conveying roller drive main gear 242 drives the... Figure 3 The rightmost plastic sheet left conveying roller gear 2511 shown is the first plastic sheet left conveying roller gear 2511 on the plastic sheet left conveying roller shaft 251 of a set of plastic sheet left conveying rollers 25, which rotate clockwise in a chain reaction, and correspondingly cause a set of plastic sheet left conveying rollers 25 to rotate clockwise in sync.

[0036] Please see Figure 1 and Figure 4The preferred, but not absolutely limited, structure of the aforementioned plastic sheet stamping mechanism 4 is as follows: it includes a front lifting sliding guide rail fixing column 41 for the stamping plate frame, a rear lifting sliding guide rail fixing column 42 for the stamping plate frame, a stamping plate frame 43, a stamping plate 44, a stamping plate frame drive cylinder support beam 45, a stamping plate frame drive cylinder 46, and a set of stamping plate thrust cylinders 47. The lower end of the front lifting sliding guide rail fixing column 41 is welded and fixed to the front right end of the aforementioned frame front upper beam 105a of the aforementioned frame 10, while the upper end extends upward. A front lifting sliding guide rail for the stamping plate frame is longitudinally fixed with screws on the side of the front lifting sliding guide rail fixing column 41 facing the rear lifting sliding guide rail fixing column 42 of the stamping plate frame. The moving guide rail 411 and the rear lifting sliding guide rail fixing column 42 of the stamping plate frame correspond to the front lifting sliding guide rail fixing column 41 of the stamping plate frame. The lower end of the rear lifting sliding guide rail fixing column 42 of the stamping plate frame is welded and fixed to the rear right end of the aforementioned upper beam 105b of the aforementioned frame 10, while the upper end extends upward. On the side of the rear lifting sliding guide rail fixing column 42 of the stamping plate frame facing the front lifting sliding guide rail fixing column 41 of the stamping plate frame, a rear lifting sliding guide rail 421 of the stamping plate frame, corresponding to the front lifting sliding guide rail 411 of the stamping plate frame, is fixed in a longitudinal state by screws. A front slider 431 of the stamping plate frame is fixed to the front end of the stamping plate frame 43 by screws. The front slider 431 of the stamping plate frame is connected to the stamping plate. The front lifting sliding guide rail 411 is slidably engaged. A rear slider 432 of the stamping plate frame is fixed to the rear end of the stamping plate frame 43 by screws. The rear slider 432 of the stamping plate frame is slidably engaged with the rear lifting sliding guide rail 421 of the stamping plate frame. A connecting rod 433 of the stamping plate frame is fixed at the center position above the stamping plate frame 43. The stamping plate 44 is located in the middle area below the stamping plate frame 43, and the stamping plate frame 43 and the stamping plate 44 correspond to the upper part of the aforementioned plastic plate punching mechanism 5. A plurality of rows of plastic plate punching holes 441 are spaced apart on the stamping plate 44. A stamping plate thrust cylinder column connecting hole 442 is opened at each of the four corners of the stamping plate 44. The stamping plate frame drive cylinder support beam 45 is fixed between the tops of the front and rear lifting sliding guide rail fixing columns 41 and 42 of the stamping plate frame by the fixing screw 451 of the stamping plate frame drive cylinder support beam. The stamping plate frame drive cylinder 46 is a cylinder and is fixed in the middle of the upward-facing side of the stamping plate frame drive cylinder support beam 45. The stamping plate frame drive cylinder column 461 of the stamping plate frame drive cylinder 46 faces downward and extends to the lower part of the stamping plate frame drive cylinder support beam 45, connecting to the upper end of the aforementioned stamping plate frame connecting rod 433. There are four stamping plate thrust cylinders 47 (using cylinders) in a set, and they are fixed longitudinally to the upward-facing side of the stamping plate frame 43 at positions corresponding to the aforementioned stamping plate thrust cylinder column connecting holes 442.The piston rod of the stamping plate thrust cylinder 47 extends below the stamping plate frame 43 and connects to the stamping plate 44 at a position corresponding to the aforementioned piston rod connection hole 442.

[0037] In this embodiment, the aforementioned plastic sheet punching holes 441 are arranged in three rows with three holes in each row. Therefore, in this embodiment, there are nine plastic sheet punching holes 441, but obviously, this number should not be limited. When the punching plate frame drive cylinder 46 (in this embodiment, a cylinder) controlled by the electrical controller is working, for example, when the punching plate frame 43 needs to be moved downward, the punching plate frame drive cylinder column 461 extends downward, i.e., outward from the cylinder body. The punching plate frame drive cylinder column 461 pushes the punching plate frame 43 and the punching plate 43 downward through the aforementioned punching plate frame connecting rod 433. At this time, under the operation of a set of punching plate thrust cylinders 47 (in this embodiment, cylinders) also controlled by the electrical controller, the punching plate thrust cylinder column of the set of punching plate thrust cylinders 47 pushes the punching plate 44 downward so that the plastic sheet punching holes 441 on the punching plate 44 can punch the plastic sheet located below it. During the downward movement of the aforementioned stamping plate frame 43, the front and rear sliders 431 and 432 of the stamping plate frame slide downward along the front and rear lifting sliding guide rails 411 and 421 of the stamping plate frame, respectively. Since the upward movement of the stamping plate frame 43 is the opposite of the aforementioned action process, for example, the stamping plate frame drive cylinder column 461 moves upward, that is, it moves into the cylinder body, and a set of stamping plate thrust cylinder columns also moves upward, that is, they move into the cylinder body of the stamping plate thrust cylinder, so the applicant will not repeat the explanation.

[0038] Please see Figure 1 and Figure 5The preferred, but not absolutely limited, structure of the aforementioned plastic sheet punching mechanism 5 is as follows: It includes a base plate 51, a rotary punching cylinder mounting plate 52, a punching cylinder mounting plate thrust cylinder 53, a punching cylinder rotary drive motor 54, a punching cylinder rotary drive reduction gearbox 55, a transition connecting sleeve 56, a punching cylinder protective cover 57, a set of rotary punching cylinders 58, and a set of rotary punching cylinder rotary drive gears 59. The front end of the base plate 51 is fixed to the front fixing plate 511 of the base plate by screws, and the front fixing plate 511 is welded to the front fixing beam 5111 of the base plate. The front fixing beam 5111 of the base plate is fixed to the middle of the right front side of the aforementioned frame 10 in the height direction. Specifically, it is fixed to the middle front column 103a and the right front column 104 of the aforementioned frame. Between a, the rear end of the substrate 51 is fixed to the substrate rear fixing plate 512 by screws, and the substrate rear fixing plate 512 is welded and fixed to the substrate rear fixing plate fixing beam 5121. The substrate rear fixing plate fixing beam 5121 corresponds to the rear of the substrate front fixing plate fixing beam 5111 and is fixed to the middle of the height direction of the rear right side of the aforementioned frame 10. Specifically, it is fixed between the aforementioned frame middle rear column 103b and the frame right rear column 104b. A reduction gearbox clearance hole 513 is opened on the substrate 51 at the position corresponding to the aforementioned punching cylinder rotary drive reduction gearbox 55, penetrating the thickness direction of the substrate 51. The rotary cutting punching cylinder mounting plate 52 is vertically floating above the substrate 51. The rotary cutting punching cylinder mounting plate 52 faces downward. A rotary cutting punching cylinder mounting plate lifting guide post 521 is fixed longitudinally cantilevered at each of the four corners. The rotary cutting punching cylinder mounting plate lifting guide post 521 slides against the base plate 51 via a lifting guide post sleeve 5211 mounted on the base plate 51. A punching cylinder mounting plate thrust cylinder 53 is fixed longitudinally cantilevered to the center position of the aforementioned base plate 51 on the downward-facing side via a set of punching cylinder mounting plate thrust cylinder fixing screws 532. The punching cylinder mounting plate thrust cylinder column 531 of the punching cylinder mounting plate thrust cylinder 53 extends above the base plate 51, and a rotary cutting punching cylinder mounting plate push post 533 is threaded onto the cylinder head 5311 of the punching cylinder mounting plate thrust cylinder column 531. The upper end face of column 533 corresponds to and contacts the center position of the downward-facing side of the rotary punching cylinder mounting plate 52. The punching cylinder rotary drive motor 54 is longitudinally cantilevered and drives the punching cylinder rotary drive gearbox 55. The punching cylinder rotary drive gearbox 55 extends above the base plate 51 at the position corresponding to the aforementioned gearbox clearance hole 513 and forms a gearbox connecting flange 552. The punching cylinder rotary drive gearbox shaft 551 of the punching cylinder rotary drive gearbox 55 extends upward toward the aforementioned rotary punching cylinder mounting plate 52, and a punching cylinder shaft flat keyway is formed at the center position of the upper end of the punching cylinder rotary drive gearbox shaft 551. The transition connecting sleeve 56 is loosely fitted outside the punching cylinder rotary drive gearbox shaft 551.The upper end of the transition connecting sleeve 56 forms an outwardly expanding upper flange edge 561, which is preferably fixed to the downward-facing side of the aforementioned rotary cutting and punching cylinder mounting plate 52 with screws. The lower end of the transition connecting sleeve 56 forms an outwardly expanding lower flange edge 562, which corresponds to the upper part of the aforementioned gearbox connecting flange 552 and is fixed to the gearbox connecting flange 552 with screws. A plurality of rows of rotary cutting and punching cylinders 58 are arranged longitudinally above the rotary cutting and punching cylinder mounting plate 52, and each of the rotary cutting and punching cylinders 58 has a discharge outlet 581 for excess material at its center in the height direction. The upper cutting port 582 (i.e., the rotary cutting port) of the cylinder 58 communicates with the punching residue discharge port 581, and the cutting port 582 is surrounded by cutting blades 5821. A rotary punching cylinder shaft 583 is fixed at the center of the bottom of each set of rotary punching cylinders 58. A rotary punching cylinder shaft bearing 5831 is provided on the rotary punching cylinder shaft 583. The rotary punching cylinder shaft bearing 5831 is positioned within a rotary punching cylinder shaft bearing cavity 522 opened on the rotary punching cylinder mounting plate 52. The lower end of the rotary punching cylinder shaft 583 extends below the rotary punching cylinder mounting plate 52 at a position corresponding to the rotary punching cylinder shaft bearing cavity 522, and a pressure bearing 5832 and a pressure bearing limiting nut 5833 are sequentially arranged from top to bottom. The fixed nut 5833 is threaded into the limiting nut 5835 formed on the rotary punching cylinder shaft 583. In a set of rotary punching cylinders 58, the rotary punching cylinder shaft 583 of one rotary punching cylinder 58 corresponding to the aforementioned punching cylinder rotary drive reduction gearbox shaft 551 is fixed to the aforementioned punching cylinder shaft shaft through a keyway connection 5834 formed on its outer wall. A set of rotary punching cylinder rotary drive gears 59 are loosely fitted on the aforementioned rotary punching cylinder shaft 583 at a position above the rotary punching cylinder mounting plate 52 and are fixed to the bottom of the rotary punching cylinder 58 by a set of gear fixing screws 591 spaced around the rotary punching cylinder rotary drive gears 59. Two adjacent rotary cutting and punching cylinder rotary drive gears 59 in each set mesh with each other. The rotary cutting and punching cylinder rotary drive gear 59 on the rotary cutting and punching cylinder shaft 583, which corresponds to and is connected to the aforementioned rotary cutting and punching cylinder rotary drive reduction gearbox shaft 551, constitutes a direct drive gear 59a for the rotary cutting and punching cylinder rotary drive reduction gearbox shaft. A punching cylinder protective cover 57 covers the aforementioned set of rotary cutting and punching cylinders 58, and the lower edge of the protective cover 57 is fixed to the protective cover fixing screw holes 523 on the outer side of the aforementioned rotary cutting and punching cylinder mounting plate 52 via protective cover fixing screws 574. A punching residue discharge port 571 is provided on both the front and rear side walls of the protective cover 57.On the upper and lower walls of the punching tube cover 57, at corresponding positions, are provided a number of rotary punching tube clearance holes 573 equal to the number of the aforementioned set of rotary punching tubes 58. A set of rotary punching tubes 58 passes through the rotary punching tube clearance holes 573 from bottom to top and protrudes from the upper surface of the punching tube cover 57.

[0039] In this embodiment, since the aforementioned plastic sheet punching holes 441 are in three rows with three holes in each row (a total of nine holes), the number of a set of rotary cutting punching cylinders 58, a set of rotary cutting punching cylinder rotation drive gears 59, and rotary cutting punching cylinder clearance holes 573 are also in three corresponding rows with three holes in each row.

[0040] While the plastic sheet is being pressed and stamped by the aforementioned stamping plate 44, the punching cylinder mounting plate thrust cylinder 53 (using a pneumatic cylinder), controlled by the electrical controller, operates. The punching cylinder mounting plate thrust cylinder column 531 extends upward, i.e., outward from the cylinder body, and pushes the rotary punching cylinder mounting plate 52 upward under the guidance of a set of rotary punching cylinder mounting plate lifting guide columns 521 via the rotary punching cylinder mounting plate push column 533. As the rotary punching cylinder mounting plate 52 is pushed upward by the rotary punching cylinder mounting plate push column 533... As the plate moves upward, the rotary cutting and punching cylinder mounting plate 52 drives a set of rotary cutting and punching cylinders 58 mounted on it, as well as a set of rotary cutting and punching cylinder rotation drive gears 59 fixed to the bottom of the set of rotary cutting and punching cylinders 58 by a set of gear fixing screws 591. The set of rotary cutting and punching cylinders 58 protrudes upward through the rotary cutting and punching cylinder clearance hole 573, and the aforementioned punching cylinder rotation drive motor 54, punching cylinder rotation drive reduction gearbox 55, and transition connecting sleeve 56 also move upward accordingly. Simultaneously, the punching cylinder rotation drive motor 54, controlled by the electrical controller, operates, driving the punching cylinder rotation drive reduction gearbox 55. The reduction gearbox shaft 551 drives the aforementioned rotary punching cylinder shaft 583 of one of the set of rotary punching cylinders 58 connected to it via a key. This causes the aforementioned punching cylinder rotation drive reduction gearbox shaft to directly drive the gear 59a to rotate, thereby triggering a chain reaction that puts all the rotary punching cylinder rotation drive gears 59 into a rotating state. The set of rotary punching cylinder rotation drive gears 59 drives the set of rotary punching cylinders 58 to rotate, thereby causing the cutting blade 5821 to rotary cut the plastic sheet. Under the synergistic effect of the aforementioned stamping plate 44, three rows of three through holes are formed on the plastic sheet. After the stamping and rotary cutting of the plastic sheet is completed, the stamping plate frame drive cylinder 461 of the aforementioned stamping plate frame drive cylinder 46 moves upward. At the same time, the aforementioned punching cylinder rotation drive motor 54 stops working, and the punching cylinder mounting plate thrust cylinder 531 moves downward. During the above process, the stamping and rotary cutting residue generated by the cutting blade 5821 enters the rotary cutting and punching cylinder cavity of a set of rotary cutting and punching cylinders 58 from the cutting port 582, and is discharged from the residue discharge port 581. It then falls naturally to the ground through the residue discharge port 571 on the punching cylinder cover 57 and is cleaned up by personnel in a timely manner.

[0041] Please stay tuned. Figure 1 and Figure 2 See also Figure 6In this embodiment, the aforementioned plastic sheet length adjustment control mechanism 6 is laterally positioned on the left front side of the front upper beam 105a of the frame. If it is positioned on the left rear side of the rear upper beam 105b of the frame, it should be considered an equivalent technical means and still fall within the technical scope of this invention. The plastic sheet length adjustment control mechanism 6 includes a photoelectric switch bracket adjustment screw 61, a photoelectric switch bracket 62, a photoelectric switch 63, a lifting rod 64, and a lifting rod drive motor 65. The photoelectric switch bracket adjusting screw 61 is set in a horizontal position. The left end of the adjusting screw 61 is rotatably supported on the left support seat 611 of the adjusting screw via a bearing, while the right end is similarly rotatably supported on the right support seat 612 of the adjusting screw via a bearing. A rotating operating hole 613 for the adjusting screw 61 is formed at the center of the left end face and / or the right end face (i.e., it can be on the left end face, the right end face, or both). The support 611 is fixed to the front left end of the aforementioned upper front beam 105a of the frame by a pair of adjusting screw left support fixing screws 6111, while the adjusting screw right support 612 is fixed to the front left end of the aforementioned upper front beam 105a of the frame by a pair of adjusting screw right support fixing screws 6121. The photoelectric switch bracket 62 is threaded with the middle of the photoelectric switch bracket adjusting screw 61 by the photoelectric switch bracket moving nut 621 on its lower left side. The photoelectric switch 63 is connected to the photoelectric switch bracket 62 by the photoelectric switch fixing screw 631. The left side is fixed, the lifting rod drive motor 65 is mounted on the photoelectric switch 63, and a lifting rod fixing plate 6511 is fixed at the left end of the lifting rod drive motor shaft 651 of the lifting rod drive motor 65. One end of the lifting rod 64 facing the lifting rod fixing plate 6511 is fixed to the left side of the lifting rod fixing plate 6511 by the lifting rod fixing screw 641, while the other end of the lifting rod 64 is configured as a free end that falls in the direction of the aforementioned plastic plate left conveying mechanism 2 or rises in the direction away from the plastic plate left conveying mechanism 2.

[0042] When an operator uses a tool such as a screwdriver to rotate the adjusting screw 61 of the aforementioned photoelectric switch bracket by turning the operating hole 613 (a blind hexagonal socket hole), the rotation of the adjusting screw 61 causes the photoelectric switch bracket moving nut 621 to move left or right on the adjusting screw 61. This, in turn, causes the photoelectric switch bracket 62 to drive the photoelectric switch 63 and the lifting rod drive motor 65 (which uses the photoelectric switch 63 as a carrier), along with the lifting rod 64, to move left or right accordingly, thus setting the size of the plastic sheet according to process requirements. Furthermore, based on common sense, the further the photoelectric switch 63 moves to the right, the longer the plastic sheet will be, and vice versa.

[0043] Please see below.Figure 1 And see also Figure 7 and combination Figure 2 The aforementioned plastic sheet thickening and stacking mechanism 7 includes a suction cup frame front sliding guide rail fixing column 71, a suction cup frame rear sliding guide rail fixing column 72, a suction cup 73, a suction cup frame 74, a suction cup frame drive cylinder support beam 75, a suction cup frame drive cylinder 76, and a plastic sheet stacking adhesive spraying device 77. The lower end of the suction cup frame front sliding guide rail fixing column 71 is welded and fixed to the front side of the middle of the aforementioned frame front upper beam 105a, while the upper end extends upward, and a suction cup frame front sliding guide rail 711 is longitudinally fixed on the side of the suction cup frame front sliding guide rail fixing column 71 facing the suction cup frame rear sliding guide rail fixing column 72. The suction cup frame rear sliding guide rail fixing column 72 corresponds to the suction cup frame front sliding guide rail fixing column 71. The lower end of the suction cup frame rear sliding guide rail fixing column 72 is welded and fixed to the rear side of the middle of the aforementioned upper beam 105b of the frame, while the upper end extends upward. On the side of the suction cup frame rear sliding guide rail fixing column 72 facing the suction cup frame front sliding guide rail fixing column 71, a suction cup frame rear sliding guide rail 721 is fixed in a longitudinal state, with a position corresponding to the suction cup frame front sliding guide rail 711. The number of suction cups 73 is one set (four in this embodiment) and corresponds to the aforementioned left and right conveying mechanisms 2 and 3 of the plastic plate. The position of the suction cup 73 is fixed at the center of the lower part of the suction cup frame 74. In use, the suction cup 73 is connected to the negative pressure generating device via a pipeline. A front slider 741 of the suction cup frame is fixed at the front end of the suction cup frame 74, and the front slider 741 slides in cooperation with the front sliding guide rail 711 of the suction cup frame. A rear slider 742 of the suction cup frame is fixed at the rear end of the suction cup frame 74, and the rear slider 742 slides in cooperation with the rear sliding guide rail 721 of the suction cup frame. A suction cup frame connecting rod 743 is fixed at the center of the upper part of the suction cup frame 74. The suction cup frame drive cylinder support beam 75 is driven by the suction cup frame. The cylinder support beam fixing screw 751 is fixed between the tops of the front and rear sliding guide rail fixing columns 71 and 72 of the suction cup frame. The suction cup frame drive cylinder 76 (in this embodiment, a cylinder is used) is fixed in the middle of the side of the suction cup frame drive cylinder support beam 75 facing upward. The suction cup frame drive cylinder column 761 of the suction cup frame drive cylinder 76 faces downward and is threaded to the upper end of the aforementioned suction cup frame connecting rod 743 after extending below the suction cup frame drive cylinder support beam 75. The plastic sheet lamination adhesive spraying device 77 is set on the rear upper beam 105b of the aforementioned frame at the position corresponding to the right side of the suction cup 73.

[0044] As can be seen from the above, the front and rear sliding guide rail fixing columns 71 and 72 of the suction cup frame and the suction cup frame drive cylinder support beam 75 together form a gantry frame, i.e., a ⊓-shaped structure; the aforementioned front and rear sliding guide rail fixing columns 11 and 12 of the cutting blade frame and the cutter frame drive cylinder support beam 15 together also form a gantry frame, i.e., a ⊓-shaped structure; the aforementioned front and rear lifting sliding guide rail fixing columns 41 and 42 of the stamping plate frame and the stamping plate frame drive cylinder support beam 45 together also form a gantry frame, i.e., a ⊓-shaped structure.

[0045] Under the operation of the suction cup frame drive cylinder 76 (i.e., the cylinder) controlled by the electrical controller, the suction cup frame drive cylinder column 761 extends downwards, extending outwards from the cylinder body. This drives the suction cup frame 74 downwards via the suction cup frame connecting rod 743. The suction cup frame 74 then drives a set of suction cups 73 downwards. At this time, with the suction cups 73 connected by pipelines and the aforementioned negative pressure generating device (such as a vacuum pump), a negative pressure is generated in the suction cups 73, causing them to hold the first (or first) plastic sheet. Then, the suction cup frame drive cylinder 76 reverses its operation, causing the set of suction cups 73 holding the plastic sheet to move upwards. When the next (or second) plastic sheet is delivered below the first plastic sheet held by the set of suction cups 73 and positioned above it, the plastic sheet bonding adhesive spraying device 77, controlled by the electrical controller, sprays the upper surface of the next (or second) plastic sheet in an atomized state with plastic sheet bonding adhesive (also called "diluent"). Next, the aforementioned suction cup holder drive cylinder 76 operates again, causing a set of suction cups 73, along with the first plastic sheet they hold, to descend and adhere to the second plastic sheet. After a delay of 2-3 seconds, the aforementioned negative pressure generating device stops operating, and the suction cups 73 change from negative pressure to positive pressure, releasing the first plastic sheet they hold. Then, the suction cup holder drive cylinder 76 reverses its operation, causing the suction cups 73 to rise and return to their upper position. The stacked plastic sheet is then conveyed to the direction of the plastic sheet stamping mechanism 4 and the plastic sheet punching mechanism 5 under the operation of the aforementioned plastic sheet right conveying mechanism 3. Punching is then performed by the combined action of the plastic sheet stamping mechanism 4 and the plastic sheet punching mechanism 5, as described above.

[0046] In this embodiment, the plastic sheet bonding adhesive mentioned above is preferably, but not absolutely limited to, the MD-Ⅱ environmentally friendly adhesive produced and sold by Shenzhen Mingde Materials Co., Ltd. in Guangdong Province, China.

[0047] Please pay attention. Figure 7 And combined Figure 1 and Figure 2The aforementioned plastic sheet composite adhesive spraying device 77 includes an atomizer bracket 771 and an atomizer 772. The lower end of the atomizer bracket 771 is fixed to the upward-facing side or front side of the aforementioned upper rear beam 105b of the frame, or it can be fixed to the front side of the upper rear beam 105b of the frame. Figure 7 As shown, a bracket fixing foot 7711 is folded out at the lower end of the atomizer bracket 771, and a bracket fixing foot screw hole 77111 is formed on the bracket fixing foot 77111. The bracket fixing foot 771 is fixed to the upward-facing side of the rear upper beam 105b of the frame by screws at the positions corresponding to the bracket fixing foot screw hole 77111. The atomizer 772 has an air inlet 7721, a glue inlet 7722, a glue nozzle 7723, and a glue spray volume adjustment knob 7724. Interface 7721 is located on the left side of atomizer 772 and is connected to the compressed air supply device pipeline in use. Glue inlet interface 7722 is located on the right side of atomizer 772 and is connected to the plastic sheet bonding glue supply device via a pipeline in use. Glue nozzle 7723 is located on the front side of atomizer 772 and is fixed to the upper end of atomizer bracket 771. The glue nozzle 7723 faces the aforementioned plastic sheet right conveying mechanism 3. Glue amount adjustment knob 7724 is located on the rear side of atomizer 772.

[0048] Pressurized air is supplied to the atomizer 772 by a pressurized air supply device such as an air compressor connected by a pipeline, and plastic sheet bonding adhesive is supplied to the atomizer 772 by a plastic sheet bonding adhesive supply device connected by a pipeline. The supply of air and adhesive can be adjusted and controlled by the pressurized air supply device and the plastic sheet bonding adhesive supply device, which are controlled by an electrical controller, respectively. The amount of plastic sheet bonding adhesive sprayed from the adhesive spraying gap 77231 of the adhesive spraying nozzle 7723 (or a group of densely arranged adhesive spraying micro-holes on the edge of the adhesive spraying nozzle) can be adjusted by adjusting the adhesive spraying amount adjustment knob 7724.

[0049] In the aforementioned pair of plastic plate mid-journey release control mechanisms 8, since the structure of the plastic plate mid-journey release control mechanism 8 located at the rear middle of the aforementioned rear upper beam 105b of the frame is the same as the structure of the plastic plate mid-journey release control mechanism 8 located at the front middle of the aforementioned front upper beam 105a of the frame, the applicant will only describe the plastic plate mid-journey release control mechanism 8 located at the front middle of the front upper beam 105a of the frame below. This plastic plate mid-journey release control mechanism 8 located at the front middle of the front upper beam 105a of the frame includes a photoelectric sensor. The system includes a switch mounting bracket adjusting screw 81, a photoelectric sensor switch mounting bracket 82, a photoelectric sensor switch 83, a lifting stop lever 84, and a lifting stop lever drive motor 85. The photoelectric sensor switch mounting bracket adjusting screw 81 is horizontally positioned. Its left end is rotatably supported on a left adjusting screw support 811, while its right end is rotatably supported on a right adjusting screw support 812. An equivalent [missing information - likely a device or mechanism] is formed at the center of the left and / or right end faces of the photoelectric sensor switch mounting bracket adjusting screw 81. The aforementioned photoelectric switch bracket adjusting screw rotation operation hole 613, the photoelectric sensor switch bracket adjusting screw rotation operation hole 813, the left support seat 811 and the right support seat 812 of the adjusting screw are fixed to the front middle of the aforementioned upper front beam 105a of the frame. The photoelectric sensor switch mounting bracket 82 is threaded with the middle of the adjusting screw 81 of the photoelectric sensor switch mounting bracket through the photoelectric sensor switch mounting bracket moving nut 821 on its lower left side. The photoelectric sensor switch 83 is mounted on the photoelectric sensor switch mounting bracket through the photoelectric sensor switch fixing screw 831. The left side of the bracket 82 is fixed, the lifting and lowering lever drive motor 85 is mounted on the photoelectric sensor switch 83, and a lifting and lowering lever fixing plate 851 is fixed at the left end of the lifting and lowering lever drive motor shaft of the lifting and lowering lever drive motor 85. One end of the lifting and lowering lever 84 facing the lifting and lowering lever fixing plate 851 is fixed to the left side of the lifting and lowering lever fixing plate 851 by lifting and lowering lever fixing screws, while the other end of the lifting and lowering lever 84 is configured as a free end that falls in the direction of the aforementioned plastic plate right conveying mechanism 3 or rises in the direction away from the plastic plate right conveying mechanism 3.

[0050] Since the structure and function of the mid-way release control mechanism 8 for a pair of plastic boards, as well as the process of adjusting the adjustment screw 81 of the photoelectric sensor switch mounting bracket to move the photoelectric sensor switch mounting bracket 82 together with the photoelectric sensor switch 83, are the same as those of the aforementioned plastic board length adjustment control mechanism 6, the applicant will not elaborate further.

[0051] See you later Figure 1 and Figure 2In the aforementioned pair of punching termination plastic plate release control mechanisms 9, since the structure of the punching termination plastic plate release control mechanism 9 located on the right rear side of the aforementioned upper beam 105b of the frame is the same as the structure of the punching termination plastic plate release control mechanism 9 located on the right front side of the aforementioned upper beam 105a of the frame, the applicant will only describe the latter. The punching termination plastic sheet release control mechanism 9, located on the right front side of the upper front beam 105a of the frame, includes a photoelectric sensing switch bracket 91, a photoelectric sensing switch 92, a rotating stop bar 93, and a rotating stop bar drive motor 94. The photoelectric sensing switch bracket 91 is fixed to the right front side of the aforementioned upper front beam 105a of the frame. The photoelectric sensing switch 92 is fixed on the photoelectric sensing switch bracket 91. The rotating stop bar drive motor 94 is located on the photoelectric sensing switch 92. The rotating stop bar drive motor shaft of the rotating stop bar drive motor 94 faces upward and is fixed with a rotating stop bar fixing plate 941. The front end of the rotating stop bar 93 is fixed to the rotating stop bar fixing plate 941, and the rear end is configured as a free end and corresponds to the right side of the aforementioned plastic sheet punching mechanism 4.

[0052] When the stacked plastic sheets touch the photoelectric sensing switch 92, the photoelectric sensing switch 92 sends a signal to the electrical controller. The aforementioned plastic sheet stamping mechanism 4 and plastic sheet punching mechanism 5 of the electrical controller then operate as described above. After the set time, i.e., the set delay time, is reached, the electrical controller sends a working signal to the plastic sheet right conveying device 3. Furthermore, the rotating stop bar drive motor 94 of the pair of punching-finish plastic sheet release control mechanisms 9 also operates under the signal from the electrical controller, causing the rotating stop bar 93 to move from... Figure 1 and Figure 2 The state shown is rotated 90° to release the closure of the plastic plate exit channel at the upper right end of the frame 10, and the stacked and punched plastic plate exits through the aforementioned plastic plate exit channel.

[0053] Because the position of the plastic sheet length adjustment control mechanism 6 and the position of the pair of plastic sheet mid-journey release control mechanisms 8 can be adjusted accordingly, the length of the plastic sheet is both controllable (by adjusting the position of the photoelectric switch 63) and precise. At the start of operation, the lifting lever 64 of the plastic sheet length adjustment control mechanism 6 and the lifting stop levers 84 of the pair of plastic sheet mid-journey release control mechanisms 8 are both in a lowered state, or in a horizontally lowered state. The plastic sheet is conveyed to the left by the left conveying mechanism 2. When the plastic sheet is detected by the length adjustment control mechanism 6 and touches the lifting bar 64 on the right end face of the plastic sheet, the lifting bar 64 is raised. At the same time, the cutting blade 14 of the plastic sheet cutting mechanism 1 cuts the plastic sheet. After a set time, the first plastic sheet that was previously cut passes through the length adjustment control mechanism 6 and the lifting bar 64 falls again. The above process is repeated and the cutting blade 14 of the plastic sheet cutting mechanism 1 cuts the second plastic sheet that is input. During this process, the first plastic sheet enters the station of the plastic sheet thickening and stacking mechanism 7. The first plastic sheet is detected by the photoelectric sensor switch 83 of the pair of plastic sheet mid-way release control mechanism 8 and touches the lifting bar 84 on the right end face of the plastic sheet. The left conveying mechanism 2 of the plastic sheet stops working (i.e., stops conveying). At this point, as described above by the applicant, a set of suction cups 73 picks up the first plastic sheet. Because the first plastic sheet is held by the suction cups 73, the photoelectric sensor switch 83 cannot detect it. Under the operation of the left conveying mechanism 2, the second plastic sheet is conveyed towards the mid-way release control mechanism 8. After the photoelectric sensor switch 8 detects that the second plastic sheet has touched the lifting stop bar 84, the left conveying mechanism 2 stops conveying (i.e., pauses operation). During this period, the aforementioned plastic sheet bonding adhesive spraying device 77 sprays plastic sheet bonding adhesive (diluent) onto the second plastic sheet. Then, as described above by the applicant, the operation of the plastic sheet thickening and bonding mechanism 7 causes the first plastic sheet previously held by the set of suction cups 73 to bond with the surface... The second plastic sheet, coated with a plastic sheet bonding adhesive, is stacked. After a set delay time, such as 2-3 seconds, the lifting stop 84 rises. Under the operation of the plastic sheet right conveying mechanism 3, the stacked thick plastic sheet is conveyed to the right. When the thick plastic sheet is detected by the photoelectric sensing switch 92 of the pair of punching termination plastic sheet release control mechanisms 9, and the right end face of the stacked thick plastic sheet touches the rotating stop bar 93, according to the applicant's description above of the plastic sheet punching mechanism 4 and the plastic sheet punching mechanism 5, nine holes are punched in the thick plastic sheet through the cooperation of the plastic sheet punching mechanism 4 and the plastic sheet punching mechanism 5. After the set time, such as 2-3 seconds, is reached, the rotating stop bar 93 releases the closure of the plastic sheet exit channel at the upper right end of the aforementioned frame (i.e., opens the plastic sheet exit channel). The aforementioned process is repeated to punch holes in the plastic sheet efficiently and with a relay effect.

[0054] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
