Description

Technical Field

[0001] The present invention relates to the technical field of processing of packaging printed matter, and particularly relates to a floating intermittent die-cutting machine. Background Art

[0002] The die-cutting process is one of the most commonly used processes for packaging printed matter. The main process of the die-cutting process is: mounting the plate → adjusting the pressure → determining the registration → pasting the base material auxiliary materials → trial die-cutting → formal die-cutting and indentation → waste removal → finished product winding or sheet cutting → counting and packaging, which is mainly used for die-cutting of some corresponding non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone gasket, etc.

[0003] After retrieval, the patent with the publication number CN202558348U discloses a floating intermittent flat-bed die-cutting machine. The intermittent feeding or small feeding of paper is achieved by changing the rotation speed and direction of the floating motor, and then regulating the movement of the synchronous belt, and further controlling the movement of the floating guide roller seat and the floating guide roller to achieve the effect of tensioning the paper and achieving the purpose of preventing the paper from running off.

[0004] Although the existing device has improved the tensioning of paper for intermittent feeding and small feeding, its conveyance of the rolled material is completed by the unwinding mechanism and the winding mechanism. In this way, the material cannot be cut during conveyance in this device, otherwise the material wound on the unwinding mechanism and the winding mechanism will be disconnected, and then the material on the unwinding mechanism cannot be conveyed along the predetermined path. For this reason, this device has to cut the material behind the winding mechanism, which is not only inconvenient to operate but also difficult to control the length of each cut sheet, and will affect the die-cutting processing rate. In view of this, we propose a floating intermittent die-cutting machine. Summary of the Invention

[0019] Beneficial effects

[0020] The technical solution provided by the present invention has the following beneficial effects compared with the known public technology:

[0021] 1. The present invention is provided with a moving seat, a guide rod and a swivel ring. The reciprocating movement of the moving seat can be realized under the cooperation of the three and other structures provided on them. Then, through the extrusion plate, the top plate and the shearing assembly, the printed products on the conveyor belt can be subjected to synchronous die-cutting indentation and sheet cutting operations, which can not only effectively improve the production efficiency, but also better control the die-cutting indentation position and the sheet cutting position.

[0022] 2. The present invention is provided with a transmission mechanism. Through the drive of the transmission mechanism, the fixed-length conveying of the printed products and the die-cutting of the printed products can be respectively realized. Moreover, in the process of realizing the two operations, there is no need for the staff to spend much effort. It can be achieved by the continuous drive of the motor on the disk, which greatly improves the die-cutting processing efficiency of the device for the printed products.

[0023] 3. The present invention is provided with a shearing assembly, which structure enables the device to cut printed products in an effect similar to that of scissors. Cutting the printed products into sheets by shearing force not only increases the shearing speed, but also ensures that the cut edges of the printed products are smoother. At the same time, compared with the direct pressure cutting method, the reaction force on the cutter of the device is smaller, which can greatly reduce the wear of the cutter, thereby extending the service life of the shearing assembly of the device.

[0024] 4. The present invention is provided with a transition plate, a side plate, a tooth column B and a tooth column C. Through the cooperation relationship of the above structures, the side plate in the device will drive the transition plate to extend and retract respectively before conveying the printed product and before die-cutting the printed product, and the provision of multiple tooth columns C can enable the tooth column B to drive the side plate to retract or extend at the fastest speed, thereby ensuring that the transition plate can have a lifting and supporting effect on the printed product or does not hinder the shearing component. Furthermore, through the compression spring and the sliding groove of the sliding block that slides with each other, the tooth column B can have a certain activity space after driving the side plate to reach the specified position, thereby preventing the tooth column C from interrupting the movement of the side plate and causing damage to the side plate.

Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0037] A floating intermittent die-cutting machine includes an outer shell 1. The interior of the outer shell 1 has a U-shaped structure. Four drums 2 are rotatably connected inside the outer shell 1. The distance between the two drums 2 in the middle is relatively close. A conveyor belt 3 is connected between the outer walls of the two drums 2 at the front side and between the outer walls of the two drums 2 at the rear side. The side wall of the conveyor belt 3 is in sliding contact with the inner wall of the outer shell 1. A support plate 4 in sliding contact with the conveyor belt 3 is provided on the inner side of the conveyor belt 3. A transition plate 5 is provided between the two support plates 4. A transmission mechanism 6 is installed inside the right wall of the outer shell 1;

[0038] The transmission mechanism 6 includes a motor 7 fixedly provided on the right wall of the outer shell 1, a disc 8 coaxially and fixedly connected to the output end of the motor 7, a plurality of tooth columns A9 fixedly provided on the outer wall of the disc 8 in a one-third arc-shaped and equally spaced structure, two gears 10 symmetrically provided on both sides of the disc 8, a rotating shaft 11 coaxially and fixedly connected to the left end of the gear 10, a transmission belt 12 connected between the right ends of the two rotating shafts 11, a control panel 13 coaxially and fixedly connected to the left end of the rotating shaft 11, a swivel 14 provided to the left of the control panel 13 at the front side, a guide rod 15 slidably connected inside the swivel 14, and a moving seat 16 fixedly provided at the left end of the guide rod 15;

[0039] A cavity 17 that is slidably engaged with the moving seat 16 is provided on the left inner wall of the outer shell 1. A shearing assembly 18 is provided in the right part of the cavity 17. The shearing assembly 18 includes two cutting knives 19 arranged in a centrosymmetric structure and a fixed seat 20 fixedly provided at the left end of the cutting knife 19. The shearing assembly 18 is used to cut the materials on the conveyor belt 3.

[0040] Specifically, both ends of the support plate 4 are respectively connected and fixed to the inner walls on both sides of the outer shell 1. The cross-section of the support plate 4 and the cross-section of the conveyor belt 3 are both U-shaped structures. Such a structure can prevent the materials on the conveyor belt 3 from deviating from the specified path during transportation and prevent the problem of inclination during die-cutting operations. The inner wall of the support plate 4 at the rear is a symmetric inclined surface structure. Such a design makes the inside of the support plate 4 at the rear a trapezoidal column structure with a larger front and a smaller rear. In this way, when the materials are cut and then conveyed backward, they can be guided, and then continue to travel along the specified path, ensuring that the cutting knife 19 of the shearing assembly 18 is always perpendicular to the materials. A plate groove 21 that is slidably engaged with the transition plate 5 is provided on the rear wall of the support plate 4 at the front. When the shearing assembly 18 cuts the printed products, the transition plate 5 will be driven by the transmission mechanism 6 and retracted into the plate groove 21 to avoid obstructing the cutting knife 19. The transition plate 5 is in an inclined structure with a lower front and a higher rear, and the rear end of the top surface is flush with the top surface of the support plate 4 at the rear. In this way, the position of the plate groove 21 will be lower than the top surface position of the support plate 4 at the front, so that the plate groove 21 will not affect the movement of the printed products from the top surface of the support plate 4 at the front. Moreover, with the setting of the transition plate 5, it can also lift the printed products, enabling the device to provide a stable support surface for the backward movement of the printed products without affecting the cutting of the printed products by the shearing assembly 18, and at the same time, it can also lift them to the top surface position of the support plate 4 at the rear.

[0041] Furthermore, a side plate 22 is fixedly arranged on the right wall of the transition plate 5. The side plate 22 is an L-shaped structure with a small front and a large rear. The side plate 22 is slidably connected to the inner wall of the right side of the shell 1. The front of the bottom of the side plate 22 is provided with a plurality of tooth columns B23 in a linear and equidistant structure. The upper ends of the plurality of tooth columns B23 located in the middle are all connected and fixed to the bottom surface of the side plate 22. The top surfaces of the two tooth columns B23 located at the front and rear ends are fixed with sliders 24. The bottom surface of the side plate 22 is provided with a slide groove 25 that slidably cooperates with the slider 24. A compression spring 26 is fixedly arranged between the slider 24 and the slide groove 25. The outer wall of the rotating shaft 11 located on the front side is provided with a plurality of tooth columns C27 that mesh with the tooth columns B23 in an annular and equidistant structure. During the forward and reverse rotation of the rotating shaft 11, the plurality of tooth columns C27 can also produce different directions of shifting on the tooth columns B23, and then the side plate 22 can drive the transition plate 5 along the plate groove 21 The side plate 22 and the housing 1 move forward or backward in the direction of the sliding connection, and under the action of the two toothed columns B23 elastically connected by the slider 24, the slide groove 25 and the compression spring 26 at both ends, when the rotating shaft 11 drives the side plate to the front or rear end, the toothed column C27 thereon continues to produce a toggling effect on the toothed column B23, which will be resolved by the sliding cooperation between the slider 24 and the slide groove 25. At this moment, the compression spring 26 can also push the toothed column B23 back to its original position after being toggled. In this way, not only can the side plate 22 and the transition plate 5 change their positions as the device realizes different operations, but also the design of multiple toothed columns C27 can make the side plate 22 drive the transition plate 5 to reach the corresponding position at the fastest speed, rather than rotating one circle or even longer to achieve the effect, and at the same time, it can avoid the continuous rotation of the rotating shaft 11 to damage the toothed column B23.

[0042] Furthermore, the right inner wall of the shell 1 is provided with a cavity 28 that slidably cooperates with the disc 8, the gear column A9, the gear 10, the shaft 11, the transmission belt 12 and the gear column C27. The cavity 28 not only provides an installation position for multiple structures, but also limits the position of multiple structures. The output end of the motor 7 extends through the right wall of the shell 1 to the cavity 28 corresponding to the disc 8 and is coaxially fixed thereto. The gear column A9 is meshingly connected with the gear 10. Because the gear column A9 is arranged in a one-third arc-shaped equal-pitch structure, there will be a pause in the process of the gear column A9 disengaging from the meshing with the gear 10 on one side and switching to the meshing with the gear on the other side, so as to prevent the problem of too fast forward and reverse conversion while the other structures have not yet adapted. On the other hand, the two shafts 11 are connected to each other by a transmission belt 12, so that the two shafts 11 will keep rotating in the same direction and at the same speed. The two shafts 11 are respectively connected to the two rollers 2 located in the middle and coaxially therewith. Rotationally connected, the two control disks 13 and the rotating ring 14 are rotationally connected to the shell 1, and the left walls of the two rollers 2 located in the middle are both annular and equidistantly spaced elastically connected with a plurality of clamping blocks A29, and the right wall of the control disk 13 is provided with a clamping groove A30 that is clamped and matched with the clamping block A29. In the process of the tooth column A9 being meshed and connected with the front side gear 10, the clamping groove A30 on the control disk 13 will have a pushing effect on the right-angled side of the clamping block A29, and then the roller 2 will rotate in the same direction as the control disk 13 and the rotating shaft 11, and then the conveyor belts 3 on the front and rear sides will transport the printed products backward under the action of the roller 2, and the front side gear 10 can be rotated multiple times by the multiple tooth columns A9, so that the conveyor belt 3 can move backward for a total circumference of a corresponding number of circles, and the printed products thereon will also be transported backward by the same length. In summary, the fixed-length conveying effect of the printed products can be achieved, which is convenient for the subsequent fixed-length cutting of the printed products into sheets by the device.

[0043] Furthermore, a plurality of clamping blocks B31 are elastically connected to the right wall of the swivel ring 14 at equal intervals in a circular structure. A clamping groove B32 that is in clamping fit with the clamping blocks B31 is formed in the left wall of the control disk 13. The left end of the clamping block A29 and the right end of the clamping block B31 are both in the structure of a right-angled triangular prism. The plurality of clamping blocks A29 and the plurality of clamping blocks B31 are arranged in a centrosymmetric structure. Because the clamping blocks B31 and the clamping blocks A29 are arranged in a centrosymmetric structure, during the process that the control disk 13 pushes the clamping blocks A29 to make the roller 2 rotate, the clamping groove B32 will continuously contact the inclined surface part of the clamping blocks B31. Moreover, the clamping blocks B31 and the swivel ring 14 are elastically connected. In this way, under the extrusion of the clamping groove B32, the clamping blocks B31 will continuously shrink into the swivel ring 14. Thus, the swivel ring 14 will not rotate in the same direction as the roller 2. The frictional force at the position where the swivel ring 14 is rotatably connected to the outer shell 1 is greater than the force that the clamping groove B32 squeezes the clamping blocks B31 into the swivel ring 14. A guide block 33 is fixedly arranged on the inner top surface of the swivel ring 14. An annular curve groove 34 that is in sliding fit with the guide block 33 is formed in the outer wall of the guide rod 15. The guide rod 15 is slidably connected to the outer shell 1. When the tooth column A9 is meshed and connected with the rear gear 10, the two rotating shafts 11 and the two control disks 13 will synchronously change the rotation direction. At this moment, the clamping blocks A29 on the roller 2 will be continuously squeezed into the roller 2 by the clamping grooves A30. The clamping blocks B31 and the clamping grooves B32 will act on each other in the same way as the clamping blocks A29 and the clamping grooves A30 before. Subsequently, the swivel ring 14 and the control disk 13 can rotate together. Then, under the sliding fit of the guide block 33 and the annular curve groove 34, the guide rod 15 can reciprocate back and forth along the position where it is slidably connected to the outer shell 1, and at the same time drive the moving seat 16 to move back and forth along the cavity 17. The shearing assembly 18 connected to the rear part of the moving seat 16 will also move synchronously. Furthermore, under the influence of other structures, the printed matter will be cut.

[0044] Furthermore, the front parts of the moving seat 16 and the cavity 17 are both U-shaped structures. The guide rod 15 is fixedly connected to the lower end of the front side of the left wall of the moving seat 16. An extrusion plate 35 is fixedly provided at the upper end of the front side of the left wall of the moving seat 16. The upper part and the rear part of the front side of the cavity 17 are both communicated with the inside of the outer shell 1. An elastic connection is provided between the inner top surface of the outer shell 1 and the end of the extrusion plate 35. The right part of the bottom surface of the extrusion plate 35 is a slope structure. The left end of the top surface of the top plate 36 is a slope structure and is in extrusion cooperation with the end of the extrusion plate 35. A die-cutting plate 37 is installed on the bottom surface of the top plate 36. The die-cutting plate 37 can be connected to the bottom surface of the top plate 36 by screws and nuts, or can be connected by tenon and mortise or snap-fit structures. Workers can actively replace die-cutting plates 37 with different patterns according to needs to adapt to the needs of different printed products. Under the cooperation of the inclined bottom surface of the extrusion plate 35 and the inclined top surface of the top plate 36, when the moving seat 16 moves, the extrusion plate 35 will squeeze the top plate 36 and the die-cutting plate 37 installed on its bottom surface downward together. During the reciprocating movement of the guide rod 15, the moving seat 16 will also drive the extrusion plate 35 to squeeze the top plate 36 multiple times. Subsequently, the die-cutting plate 37 on the bottom surface of the top plate 36 will also repeatedly perform die-cutting operations on the same position of the printed product, which can effectively enhance the die-cutting effect and avoid the problem of inconsistent clarity of die-cutting contours on the same printed product.

[0045] It is worth introducing that a through hole 38 is provided at the rear part of the moving seat 16. The inner walls on both sides of the through hole 38 are both convex-shaped structures. The cutting knives 19 and the fixed seats 20 are both arranged in an inverted trapezoidal structure with the outer part larger and the inner part smaller. The two cutting knives 19 and the two fixed seats 20 form a structure similar to scissors. The fixed seat 20 is in an L-shaped structure. A central axis 39 is fixedly provided at the right end of the outer wall of the fixed seat 20. The outer end of the central axis 39 is rotatably connected to the middle part of the inner wall of the through hole 38. A coil spring 40 is sleeved on the outer end of the central axis 39. If the fixed seat 20 rotates along the position of the rotation connection of the central axis 39 and the through hole 38, it will cause the coil spring 40 to tighten. When there is no external force, the coil spring 40 will rotate back to restore the fixed seat 20 and the central axis 39 to their original positions.

[0046] It should be noted that an inner cavity 41 is provided inside the moving seat 16 at a position corresponding to the spiral spring 40. The outer end of the spiral spring 40 is fixedly connected to the inner wall of the inner cavity 41. A guide plate 42 is fixedly provided on the left wall of the cavity 17 at a position corresponding to the outer end of the fixed seat 20. A guide groove 43 is provided on the inner wall of the guide plate 42. The guide groove 43 is arranged in a wavy structure. The outer end of the fixed seat 20 is in sliding fit with the bottom surface of the guide groove 43. Both sides of the outer end of the fixed seat 20 are in a semi-cylindrical structure. In such a structure, the sliding contact between it and the guide groove 43 is smoother, avoiding the problem that the guide groove 43 hinders the movement of the fixed seat 20. During the process of the moving seat moving to the right, the fixed seat 20 will drive the cutting knife 19 to swing continuously along the position of the central axis 39 under the promotion of the wavy structure of the guide groove 43. In this way, the two cutting knives 19 can produce an effect similar to that of scissors cutting, which can greatly improve the cutting effect on the printed matter, enabling any of the non-metallic materials, self-adhesive labels, EVA, double-sided tape, and rubber pads on this device to be easily cut into pieces, greatly improving the die-cutting efficiency of this device.

[0047] Working principle: When the staff uses this device to process printed matter, the corresponding die-cutting plate 37 for die-cutting can be first installed on the bottom surface of the top plate 36, and then the transmission mechanism 6 can be started. Driven by the motor 7, the disc 8 will rotate in a circle, and then through the tooth column A9, the two rotating shafts 11 connected to each other by the transmission belt 12 can perform intermittent synchronous forward and reverse rotations. Subsequently, under the action of the control panel 13, when the tooth column A9 meshes with the front-side gear 10, the roller 2 can be driven to rotate by itself through the rotating shaft 11 and the control panel 13, thereby transporting the materials on the conveyor belt 3 backward. When the tooth column A9 meshes with the rear-side gear 10, it will drive the moving seat 16 to move along the cavity. Then, under the promotion of the structure on the moving seat 16, the materials on the rear-side conveyor belt 3 are cut off and the materials on the front-side conveyor belt 3 are die-cut at the same time. Finally, the staff only needs to use an external container to collect the materials that have been die-cut and processed at the rear end of the rear-side conveyor belt 3.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
