Abstract
Description
Technical Field
[0001] This utility model relates to the printing field, and in particular to an online waste removal and finished product separation and collection device that uses a single-sheet paper conveying method for post-printing die-cutting and waste removal processing of cards and hang tags. Background Technology
[0002] In the post-printing die-cutting of sheet materials such as cards and hang tags, sheet-fed rotary or flatbed automatic die-cutting machines are commonly used, and their finished product collection methods are basically the same: the finished sheets are collected and stacked on the receiving table of the receiving section. Commonly used sheet-fed flatbed automatic die-cutting machines include... Figure 1 As shown:
[0003] Typically, after printing, single sheets of paper or sheet material are stacked on the paper feeding section of the die-cutting machine and fed one by one into the main die-cutting section to be die-cut into products such as cards or tags. The finished paper or sheet material is then stacked one by one on the receiving platen of the die-cutting machine. Afterwards, the waste edges from the die-cutting are removed manually or by a separate waste removal device, and the finished cards, tags, etc., are collected.
[0004] The existing technology has the following drawbacks;
[0005] 1. Existing die-cutting machines only complete "die-cutting + paper stacking". Waste edge removal and finished product separation require manual labor or separate equipment. The process is scattered, occupies a large area, and has high labor costs.
[0006] 2. Existing technologies use manual tearing of waste cards, which can easily damage them and result in fluctuating finished product qualification rates; independent waste removal machines require secondary positioning, leading to large cumulative errors.
[0007] 3. Finished products and waste are stacked together, requiring additional space and personnel for subsequent sorting, resulting in low automation. Utility Model Content
[0008] The utility model description section introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0009] The technical problem to be solved by this utility model is to provide an online waste cleaning and finished product separation and collection device that can complete waste cleaning, separation and finished product collection in one go.
[0010] To solve the above-mentioned technical problems, the present invention provides an online waste removal and finished product separation and collection device, which is used for waste removal and separation after product die-cutting processing, including:
[0011] The paper receiving and conveying unit, located below the paper receiving unit of the automatic die-cutting machine, has a paper receiving and conveying belt driven by servo motor I, which is used to receive and convey the die-cut sheets of paper along the X direction; a pressure bar that can be adjusted up and down is provided above the paper receiving and conveying belt. The pressure bar presses on the waste edge area of the paper to break the connection point between the waste edge and the finished product for the first time during the conveying process.
[0012] The separating conveyor section, located immediately downstream of the receiving conveyor section along the X direction, has a separating and conveying belt driven by a servo motor II. The upper surface of the separating and conveying belt is coplanar with the upper surface of the receiving and conveying belt, and the linear velocity v2 of the separating and conveying belt is greater than the linear velocity v1 of the receiving and conveying belt.
[0013] The separation mechanism, located between the paper receiving conveyor and the separation conveyor, includes:
[0014] The paper separating bottom roller is driven by servo motor III and has a linear speed equal to v1;
[0015] The paper-slitting buffer pressure roller assembly is used to press the finished card that has been cleaned of waste between the paper-slitting bottom roller and the separating and conveyor belt;
[0016] Guide blocks and waste collection boxes are used to guide and collect the waste edges that break off during the first pull.
[0017] In this process, when the speed difference v2 > v1, the connecting point between the separating conveyor section and the paper separating bottom roller is torn off for the second time, thus forming a single sheet of finished product on the separating and conveyor belt.
[0018] Preferably, the online waste removal and finished product separation and collection equipment is further improved by using a thin sheet of stainless steel with a thickness of 0.1mm–0.3mm and a rounded chamfer at the front end.
[0019] Preferably, in a further improvement of the online waste removal and finished product separation and collection equipment, the paper separating buffer pressure roller assembly is installed on the support crossbar II driven by the pressure roller lifting cylinder, and the pressure between the pressure roller and the paper separating bottom roller can be steplessly adjusted through the pressure control valve.
[0020] Preferably, the online waste removal and finished product separation and collection equipment is further improved by having the separation and conveyor belt surface covered with a friction layer with a friction coefficient ≥0.7.
[0021] Preferably, in a further improvement of the online waste removal and finished product separation and collection equipment, the friction layer is a polyurethane coating.
[0022] Preferably, the online waste removal and finished product separation and collection equipment is further improved by providing a counting and stacking module at the outlet of the separation and conveying section for quantitative stacking of the separated card finished products.
[0023] Preferably, the online waste removal and finished product separation and collection equipment is further improved in that the wall panels of the paper receiving conveyor and the separation conveyor share the same supporting wall panel, forming a drawer-type module that can be pushed in or pulled out as a whole under the die-cutting machine.
[0024] The working principle of this utility model is as follows;
[0025] The paper or sheet material 2 to be processed is stacked on the paper feeding section 1 of the automatic die-cutting machine. The paper or sheet material 2 is conveyed one sheet at a time to the main unit section 5 through the paper feeding section 1. The gripper bar 3 picks up the positioned paper or sheet material 2 to be processed and, driven by the chain 4, feeds the paper or sheet material 2 to be processed between the fixed platform and the movable platform 6. The die-cutting process is completed when the movable platform moves upward. Driven by the chain 4, the gripper bar 3 moves to the receiving section 11 and places the die-cut finished paper or sheet material 10 it is holding onto the receiving and conveyor belt 9 of the receiving conveyor section 43.
[0026] One end of the paper receiving and conveying unit 43 is installed below the paper receiving unit sleeve 11 of the automatic die-cutting machine. Its paper receiving and conveying belt 9 can receive the processed finished paper or sheet material 10 fed into the paper receiving unit sleeve 11 by the gripper bar 3. The paper receiving and conveying belt 9 is supported on the driving belt roller I8 located at the left end of the paper receiving and conveying unit 43 and the driven belt roller I17 located at the right end of the paper conveying unit 43. It is driven by the driving belt roller I8, which is fixedly connected to the output shaft hole of the servo motor I7. The transmission surface wall plate 44 and the operation surface wall plate 51 of the paper receiving and conveying unit are respectively supported on several support wall plates 36, forming the frame of the paper receiving and conveying unit 43. On the top surface of the transmission surface wall plate 44 and the operation surface wall plate 51 near the driven belt roller I17 of the paper receiving and conveying unit 43, a crossbar support plate 14 is symmetrically fixedly installed. Between the inner surface of the crossbar support plate 14 fixed on the transmission surface and the operation surface, a support crossbar I13 is fixedly installed. Several pressure strip mounting brackets 12 are installed on the support crossbar I13, and a thin sheet-like pressure strip 16 is fixed to the lower surface of the pressure strip mounting bracket 12. According to the product die-cutting pattern and process requirements, the pressure strips 16 are pressed onto the waste edge 45 on the upper surface of the finished paper or sheet material 10. According to the position of the waste edge 45, the pressure strip mounting brackets 12 with the pressure strips 16 fixed to them can be locked onto the support crossbar I13 by locking knob I15. The thin sheet-like pressure strip 16 hangs naturally on the upper surface of the paper delivery and conveyor belt 9, and extends to the side of the arc surface of the paper delivery and conveyor belt 9 supported on the driven belt roller I17.
[0027] Along the X direction, on the right side of the paper receiving conveyor section 43, near the paper receiving conveyor section 43, a separation conveyor section 32 is installed. The transmission surface wall plate 47 and the operation surface wall plate 50 of the separation conveyor section are also supported on several support wall plates 36, forming the frame of the separation conveyor section 32. One end of a driven belt roller II 30 is fixedly supported at the leftmost end of the operation surface wall plate 50 of the separation conveyor section; the other end of the driven belt roller II 30 is fixedly supported at a symmetrical position at the leftmost end of the transmission surface wall plate 47 of the separation conveyor section. The driven belt roller II 30 can rotate along its axis. One end of a driving belt roller II 33 is supported in a bearing hole on a belt roller fixing sleeve 49, which is fixed at the rightmost end of the operation surface wall plate 50 of the separation conveyor section. The other end of the driving belt roller II 33 is supported in a bearing hole at a symmetrical position at the rightmost end of the transmission surface wall plate 47 of the separation conveyor section. Its shaft end, extending beyond the outer side of the transmission wall plate 47 of the separating conveyor section, is fixedly connected to the output shaft hole of the servo motor II 34, which is fixed to the outer right side of the transmission wall plate 47 of the separating conveyor section. A separating and conveying belt 35 is supported on the driving belt roller II 33 and the driven belt roller II 30. The width of the separating and conveying belt 35 is the same as the width of the receiving and conveying belt 9. The upper surface of the separating and conveying belt 35 is in the same plane as the upper surface of the receiving and conveying belt 9. The servo motor II 34 can drive the separating and conveying belt 35 to move clockwise.
[0028] On the top surfaces of the transmission surface wall plate 47 and the operation surface wall plate 50 of the separation conveyor section 32, near the driven belt roller II 30, a rocker support plate 29 is symmetrically fixed. On the inner sides of the two symmetrically mounted rocker support plates 29, a paper-splitting pressure roller rocker plate 28 is symmetrically mounted on the rocker support plate 29 via hinged bolts. The paper-splitting pressure roller rocker plate 28 can swing along the axis of the hinged bolts. A paper-splitting pressure roller 27 is supported at one end in a bearing hole on the paper-splitting pressure roller rocker plate 28 on the transmission surface, and at the other end in spatially symmetrical bearing holes on the paper-splitting pressure roller rocker plate 28 on the operation surface. The paper-splitting pressure roller 27 can rotate along its axis. Under the action of gravity, the paper-splitting pressure roller 27 presses precisely on the separation and conveyor belt 35 located above the driven belt roller II 30. Furthermore, the axis of the paper-splitting pressure roller 27 is parallel to the axis of the driven belt roller II 30. The pressure of the paper separating roller 27 pressing on the separating and conveying belt 35 can be adjusted and locked by the hinge hole bolts of the paper separating roller rocker plate 28.
[0029] Between the paper receiving conveyor section 43 and the separating conveyor section 3, on the outer surfaces of the right end of the paper receiving conveyor transmission surface wall plate 44 and the left end of the separating conveyor transmission surface wall plate 47, and on the outer surfaces of the right end of the paper receiving conveyor operation surface wall plate 51 and the left end of the separating conveyor operation surface wall plate 50, a small separating mechanism wall plate 18 is fixedly installed. A servo motor III 39 is fixedly installed on the lower part of the outer surface of the small separating mechanism wall plate 18. A drive synchronous pulley 38 is fixedly connected to the output shaft of the servo motor III 39 on one side of the inner surface of the small separating mechanism wall plate 18. Vertically above the drive synchronous pulley 38, one end of a paper separating roller 26 is supported and installed in a bearing hole on the small separating mechanism wall plate 18. A driven synchronous pulley 37 is also fixedly connected to the paper separating roller 26 at a position corresponding to the drive synchronous pulley 38. A synchronous belt 52 is supported on the drive synchronous pulley 38 and the driven synchronous pulley 37. The other end of the separating roller 26 is supported and installed in a bearing hole on the small wall plate 18 of the operating surface separation mechanism. The upper tangent plane of the separating roller 26 is in the same plane as the upper surface of the separating and conveying belt 35 and the upper surface of the receiving and conveying belt 9. Driven by the servo motor III 39, the separating roller 26 can be driven to rotate clockwise through the active synchronous pulley 38 and the driven synchronous pulley 37. A pressure roller lifting cylinder 23 is fixedly installed on the top of the L-shaped curved plate of the small wall plate 18 of the transmission surface and the operating surface separation mechanism. A crossbar mounting plate 20 is symmetrically fixed to the top plate of the pressure roller lifting cylinder 23. A support crossbar II 21 is fixedly installed on the symmetrical plane of the two crossbar mounting plates 20 of the transmission surface and the operating surface, and several separating buffer pressure roller assemblies 24 are installed on the support crossbar II 21. According to the product die-cutting pattern, the paper-separating pressure rollers 25 of several paper-separating buffer pressure roller assemblies 24 can be moved and pressed onto the surface of the cleaned cards or tags 48 on the finished paper or sheet material 10. The pressure roller mounting bracket 22 of the paper-separating buffer pressure roller assembly 24 can be locked in the position adjusted by the locking knob II 19 on the support crossbar II 21.
[0030] Between the two small wall panels 18 of the separation mechanism on the transmission surface and the operation surface, near the paper receiving conveyor section 43, a guide block 41 is also fixedly installed to guide the removed waste edge 42 into the waste collection box 40.
[0031] During operation, the finished paper or sheet material 10, after die-cutting, falls onto the receiving and conveying belt 9 of the receiving and conveying section 43 via the receiving section sleeve 11. Driven by the servo motor I7, the receiving and conveying belt 9 moves forward in the X direction, causing the finished paper or sheet material 10 to pass under the pressure bar 16. Guided by the pressure bar 16 and the guide block 41, the waste edge 45 breaks off from the die-cutting connecting point 46 between itself and the card or tag 48 during the movement, becoming the cleaned waste edge 42, which is then guided into the waste collection box 40.
[0032] Simultaneously, the connected cards or tags 48, conveyed by the take-up and conveyor belt 9, pass between the separating bottom roller 26 and the separating pressure roller 25. Driven by the servo motor III 39, the rotational linear velocity of the separating bottom roller 26 is the same as the linear velocity of the take-up and conveyor belt 9. Under the control of the pressure control valve, the pressure roller lifting cylinder 23 moves slightly up or down via the cylinder top plate and the crossbar mounting plate 20 fixed to the cylinder top plate, adjusting the pressure between the separating pressure roller 25 and the separating bottom roller 26. Under the clamping and conveying action of the relative movement of the separating pressure roller 25 and the separating bottom roller 26, the connected cards or tags 48 are conveyed onto the separating and conveyor belt 35 and pass between the separating and conveyor belt 35 and the separating pressure roller 27. The separating pressure roller 27 presses against the separating and conveyor belt 35 above the driven belt roller II 30 under the action of gravity. The pressure between it and the separating and conveyor belt 35 can be manually adjusted and locked with bolts. Because the linear speed of the servo motor II 34 driving the separating and conveyor belt 35 is faster than the rotational linear speed of the paper separating bottom roller 26, under the clamping force between the paper separating pressure roller 25 and the paper separating bottom roller 26, and the clamping force between the paper separating pressure roller 27 and the separating and conveyor belt 35, the die-cutting connecting points 46 between the connected cards or tags 48 are broken. With the relatively fast movement speed of the separating and conveyor belt 35, the separated card or tag finished products 31 are formed on the separating and conveyor belt 35 in an alternating arrangement. Afterwards, these separated card or tag finished products 31 can be stacked and collected using different methods.
[0033] This utility model can achieve at least the following technical effects:
[0034] 1. The pressure strip of this utility model "nails" the waste edge to the surface of the belt. As the paper moves forward, the connecting point is subjected to concentrated tension and is instantly pulled off to complete a tear. The waste edge slides into the waste collection box along the guide block, realizing online waste removal.
[0035] 2. In this utility model, the paper separating bottom roller moves at the same speed as the paper receiving belt, keeping the cards relatively stationary; the downstream separating belt suddenly accelerates, and the connecting knife point between the cards is subjected to the dual action of speed difference shearing and pulling, reliably breaking to complete the secondary tearing and separation, forming equidistant single sheets.
[0036] 3. This utility model can control the breaking force by precisely setting v2 and v1 through a servo motor, avoiding tearing of the card body, and achieving a pass rate of ≥99.5%.
[0037] 4. This utility model allows the entire machine to be directly inserted below the paper receiving section of the die-cutting machine without altering the original machine structure. Waste removal, separation, and collection are completed in one step, saving labor and reducing floor space. Attached Figure Description

[0054] In this embodiment, after die-cutting, the finished paper or sheet material 10 falls onto the receiving and conveying belt 9 of the receiving and conveying section 43 via the receiving section sleeve 11. Driven by the servo motor 17, the receiving and conveying belt 9 moves forward in the X direction, allowing the finished paper or sheet material 10 to pass under the pressure bar 16. Guided by the pressure bar 16 and the guide block 41, the waste edge 45 breaks off from the die-cutting connecting point 46 between itself and the card or tag 48 during the movement, becoming the removed waste edge 42, which is then guided into the waste collection box 40.
[0055] Simultaneously, the connected cards or tags 48, conveyed by the take-up and conveyor belt 9, pass between the separating bottom roller 26 and the separating pressure roller 25. Driven by the servo motor III 39, the rotational linear velocity of the separating bottom roller 26 is the same as the linear velocity of the take-up and conveyor belt 9. Under the control of the pressure control valve, the pressure roller lifting cylinder 23 moves slightly up or down via the cylinder top plate and the crossbar mounting plate 20 fixed to the cylinder top plate, adjusting the pressure between the separating pressure roller 25 and the separating bottom roller 26. Under the clamping and conveying action of the relative movement of the separating pressure roller 25 and the separating bottom roller 26, the connected cards or tags 48 are conveyed onto the separating and conveyor belt 35 and pass between the separating and conveyor belt 35 and the separating pressure roller 27. The separating pressure roller 27 presses against the separating and conveyor belt 35 above the driven belt roller II 30 under the action of gravity. The pressure between it and the separating and conveyor belt 35 can be manually adjusted and locked with bolts. Because the linear speed of the servo motor II 34 driving the separating and conveyor belt 35 is faster than the rotational linear speed of the paper separating bottom roller 26, under the clamping force between the paper separating pressure roller 25 and the paper separating bottom roller 26, and the clamping force between the paper separating pressure roller 27 and the separating and conveyor belt 35, the die-cutting connecting points 46 between the connected cards or tags 48 are broken. With the relatively fast movement speed of the separating and conveyor belt 35, the separated card or tag finished products 31 are formed on the separating and conveyor belt 35 in an alternating arrangement. Afterwards, these separated card or tag finished products 31 can be stacked and collected using different methods.
