Description

Technical Field

[0001] The present application relates to the field of die-cutting machines, and in particular to a paper collection mechanism of a die-cutting machine and a die-cutting machine. Background Art

[0002] A die-cutter is a device used to cut paper, cardboard, plastic, leather, metal and other materials into specific shapes. It is widely used in packaging printing, label making, advertising production, electronic product manufacturing and other industries. The die-cutter cuts the material into a predetermined shape by combining a die-cutting plate (usually made of metal material with the shape to be cut engraved on it) with a die-cutting knife (such as a steel knife, laser knife, etc.). Under the guidance of the die-cutting plate, the die-cutting knife presses and cuts the material to separate it into the required shape.

[0003] After the die-cutting machine completes die-cutting, it generally uses a paper collection mechanism to collect and stack the paper. To ensure that the paper remains neat during the stacking process, the paper collection structure will adjust the position of the paper through some alignment devices (such as the baffle in the paper collection mechanism of the die-cutting machine with patent announcement number CN207534939U) so that it will not shift during stacking.

[0004] However, if only the alignment device is used, there may still be a situation where the paper is not aligned. Therefore, the patent with patent announcement number CN208413433U discloses a paper buffer positioning device for a paper collection mechanism of a die-cutting machine. The paper buffer positioning device is used to eliminate the moving inertia of the die-cut paper after entering the paper collection mechanism, ensuring that the die-cut paper can be transported and dropped smoothly, thereby achieving neat stacking and collection of the die-cut paper.

[0005] With respect to the above-mentioned related technologies, there is still a short distance when a new paper falls into the paper pile. When the paper falls within this distance, the paper may occasionally bend and close together. This may cause the alignment device to be unable to align the fallen paper, ultimately causing the paper stack to be uneven. Summary of the invention

[0006] In order to effectively and neatly stack and collect papers, the present application provides a paper collection mechanism of a die-cutting machine and a die-cutting machine.

[0007] In the first aspect, the present application provides a paper collection mechanism for a die-cutting machine using the following technical solution: A paper receiving mechanism of a die-cutting machine includes: A brake brush device is used to brake the paper to slow down the conveying speed of the paper; A receiving paper board, used to support and stack the paper; A paper picking device, used for releasing the paper conveyed by the paper gripper row onto the receiving paper board; The air blowing device comprises an air blowing pipe, the air blowing pipe is located above the center of the receiving paper board, the air outlet hole is opened on the pipe wall of the air blowing pipe, the air outlet hole faces downward, and the air blown from the air outlet hole is sprayed toward the center of the upper surface of the paper, so that the height of the center of the lower surface of the paper is lower than the height of the peripheral side of the lower surface of the paper when the paper falls; The paper aligning device is arranged on the peripheral side of the upper surface of the receiving paper board, and is used for reciprocatingly abutting the peripheral side edges of the papers on the receiving paper board to align the stacked papers.

[0008] By adopting the above technical solution, the paper collection mechanism of the die-cutting machine can effectively improve the neatness and stability of paper stacking. Specifically, the brake brush device moderately slows down the paper to ensure that the paper enters the paper collection board area smoothly, reducing the paper deviation or stacking misalignment caused by high-speed transportation. The air blowing device blows air at the center of the upper surface of the paper, so that the paper forms a state of being low in the middle and high around during the falling process, which helps to evenly distribute the paper and quickly attach it to the paper collection board, further improving the stacking quality. The design of the paper alignment device can not only accurately align the edges of the paper, but also automatically adjust the position after each action to ensure that each piece of paper can fall accurately in the specified position, thereby realizing an efficient and stable paper collection process.

[0009] Optionally, the blowing device further comprises: An air blowing support rod extending along the conveying direction of the paper; An air blowing slider is slidably connected to the air blowing support rod, the air blowing pipe is installed on the air blowing slider, and the air blowing pipe extends perpendicular to the paper conveying direction; The slider adjustment component is used to adjust the position of the blowing slider on the blowing support rod.

[0010] By adopting the above technical solutions, the structure of the air blowing device is more flexible and changeable. Specifically, the setting of the air blowing support rod allows the air blowing tube to freely adjust its position along the paper conveying direction, so as to adapt to paper of different sizes or shapes; the sliding connection method of the air blowing slider ensures that the air blowing tube can be accurately adjusted perpendicular to the paper conveying direction, further improving the applicability and flexibility of the equipment; the design of the slider adjustment component facilitates users to quickly and accurately adjust the position of the air blowing slider, improving the convenience of operation. These improvement measures work together to effectively ensure the stability and neatness of the paper during the paper collection process.

[0011] Optionally, the brake brush device comprises: A flap, the upper surface of which is for paper to pass through; A brush assembly comprises a brush roller and a brush fixed on the outer periphery of the brush roller, wherein a paper deceleration gap is provided between the brush and the flap for paper to pass through; The brake adjustment component is used to synchronously drive the flap and the brush roller to rotate so as to adjust the gap size of the paper deceleration gap.

[0012] By adopting the above technical solution, the synergistic effect of the flap and the brush assembly can accurately adjust the gap size of the paper deceleration gap, thereby achieving accurate braking of paper of different thicknesses or materials. In addition, the design of the braking adjustment assembly makes the operation of the entire device more flexible and convenient, and improves the adaptability and work efficiency of the equipment.

[0013] Optionally, the brake adjustment assembly includes: An operating surface bracket, the brush roller is rotatably connected to the operating surface bracket; The flap transmission component comprises a first flap transmission shaft and a flap transmission bracket, wherein the first flap transmission shaft is rotatably connected to the operating surface bracket, and the flap transmission bracket connects the first flap transmission shaft and the flap; The brake transmission component includes a brush roller swing arm, a flap drive shaft swing arm and a brush power pressure plate, wherein the brush roller swing arm is fixed to the brush roller, the flap drive shaft swing arm is fixed to the first flap drive shaft, the end of the brush roller swing arm away from the brush roller is in sliding contact with the brush power pressure plate, and the end of the flap drive shaft swing arm away from the first flap drive shaft is in sliding contact with the brush power pressure plate; The brake driving component is used to drive the brush power pressure plate to make circular motion, so as to utilize the brush power pressure plate to drive the brush roller swing arm and the flap drive shaft swing arm to swing in the opposite direction.

[0014] By adopting the above technical solution, when it is necessary to reduce the paper deceleration gap, the brake drive component drives the brush power pressure plate to make an arc motion, so that the brush roller swing arm and the flap drive shaft swing arm swing in opposite directions, thereby synchronously reducing the width of the paper deceleration gap, ensuring that the speed of the paper is effectively controlled when entering the paper collection mechanism. This design improves the stability and accuracy of the paper conveying process and reduces the problem of paper accumulation or misalignment caused by uneven speed.

[0015] Optionally, the paper collecting mechanism also includes a side panel, an operating surface bracket is slidably connected to the side panel along the paper conveying direction, a first rack is fixedly connected to the side of the side panel, a first gear is fixed to the end of the first flap transmission shaft, the first rack and the first gear are meshed, and when the gap of the paper deceleration gap becomes smaller, the flap and the brush move a distance along the paper conveying direction.

[0016] By adopting the above technical solution, when the gap of the paper deceleration gap becomes smaller, the flap and the brush can move a certain distance along the paper conveying direction. This design can avoid the problem of paper jamming or blocking caused by too small a gap when adjusting the gap size of the paper deceleration gap, thereby ensuring that the paper passes smoothly through the deceleration gap and improving the working stability and reliability of the paper collection mechanism. At the same time, this adjustable structure can also flexibly adapt to the processing of paper of different thicknesses or materials, further improving the scope of application and working efficiency of the equipment.

[0017] Optionally, an air suction hole is provided on the upper surface of the flap, and the air suction hole is located on the feeding side of the paper deceleration gap. When the paper passes through the paper deceleration gap, the air suction hole can absorb dust scraped from the upper surface of the paper.

[0018] By adopting the above technical solution, the dust scraped off by the brush can be removed in time after the paper passes through the paper reduction gap, preventing the dust from adhering to the paper surface again or scattering inside the equipment, thereby improving the cleanliness of the product and the operating stability of the equipment.

[0019] Optionally, a plurality of the air suction holes are arranged in the longitudinal and transverse directions.

[0020] By adopting the above technical solution, the dust scraped by the brush can be more effectively adsorbed during the paper deceleration process, ensuring the cleanliness of the paper while reducing the impact of dust on subsequent processes. The design of multiple suction holes makes the adsorption force distribution more uniform, further improving the dust removal efficiency.

[0021] Optionally, the paper aligning device comprises: Front and rear paper aligning components, including a front paper aligning frame and a rear paper aligning frame arranged opposite to each other; The left and right paper aligning components include a left paper aligning frame and a right paper aligning frame which are arranged opposite to each other; The paper aligning transmission assembly is used to drive the left paper aligning frame and the right paper aligning frame to perform linear reciprocating motion, and at the same time drive the front paper aligning frame and the rear paper aligning frame to perform circular reciprocating motion.

[0022] By adopting the above technical solution, compared with the traditional solution in which the paper aligning device basically performs direct reciprocating motion, the front paper aligning rack and the rear paper aligning rack can have a downward pressing action during the reciprocating motion, making the paper stacking more flat and compact.

[0023] Optionally, the paper aligning transmission assembly includes: A paper jogging swing arm, wherein the rotation axis of the paper jogging swing arm is perpendicular to the paper conveying direction; Front and rear paper jogging transmission plates, the front and rear paper jogging transmission plates are fixed to the ends of the paper jogging swing arms, the front and rear paper jogging frames and the rear paper jogging frames are fixed to the front and rear paper jogging transmission plates, and the sides of the front and rear paper jogging transmission plates are provided with inclined blocks; A guide sleeve extending perpendicular to a paper conveying direction; A guide rail seat, wherein the guide rail seat is slidably connected to the guide sleeve, the left paper aligning rack and the right paper aligning rack are fixed on the guide rail seat, and a paper aligning transmission roller is provided on the guide rail seat, and the paper aligning transmission roller can abut against the inclined surface of the inclined block to make the guide rail seat reciprocate along the guide sleeve.

[0024] By adopting the above technical solution, the paper aligning transmission assembly can ensure the synchronization of the movement of the front and rear paper aligning assemblies and the left and right paper aligning assemblies, which not only improves the overall flatness of the paper stacking, but also reduces subsequent processing problems caused by misalignment, thereby improving production efficiency and product quality.

[0025] In the second aspect, the present application provides a die-cutting machine adopting the following technical solution: A die-cutting machine comprises the above-mentioned paper collecting mechanism of the die-cutting machine.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The brake brush device moderately slows down the paper to ensure that the paper enters the paper collection area smoothly, reducing paper deviation or stacking misalignment caused by high-speed transportation. The air blowing device blows air in the center of the upper surface of the paper, so that the paper forms a state of low in the middle and high around during the falling process, which helps the paper to be evenly distributed and quickly attached to the paper collection board, further improving the stacking quality. The design of the paper alignment device can not only accurately align the edges of the paper, but also automatically adjust the position after each action to ensure that each piece of paper can fall accurately in the specified position. The above devices are used in combination to achieve an efficient and stable paper collection process; 2. When the gap of the paper deceleration gap becomes smaller, the flap and brush can move a distance along the paper conveying direction. This design can avoid paper jamming or clogging caused by too small a gap when adjusting the gap size of the paper deceleration gap, thereby ensuring that the paper passes through the deceleration gap smoothly and improving the working stability and reliability of the paper collection mechanism. At the same time, this adjustable structure can also flexibly adapt to the processing of paper of different thickness or material, further improving the scope of application and working efficiency of the equipment.

[0027] 3. There are suction holes on the upper surface of the flap, which can promptly remove the dust scraped off by the brush after the paper passes through the paper reduction gap, preventing the dust from adhering to the paper surface again or scattering inside the equipment, thereby improving the cleanliness of the product and the operating stability of the equipment.

[0040] Reference Figure 3 Specifically, the braking brush device 1 includes a flap 11, a brush assembly 12 and a braking adjustment assembly 13. The upper surface of the flap 11 is for paper to pass through. The brush assembly 12 includes a brush roller 121 and a brush 122 fixed on its periphery. A paper deceleration gap 14 is provided between the brush 122 and the flap 11 for paper to pass through. The braking adjustment assembly 13 is used to synchronously drive the flap 11 and the brush roller 121 to rotate to adjust the gap size of the paper deceleration gap 14.

[0041] In a preferred embodiment, the brake adjustment assembly 13 includes an operating surface bracket 131, a flap transmission component, a brake transmission component and a brake drive component 15. Two operating surface brackets 131 are provided and the two operating surface brackets 131 are arranged opposite to each other. The brush roller 121 is rotatably connected between the two operating surface brackets 131. The flap transmission component includes a first flap transmission shaft 132 and a flap transmission bracket 133. The first flap transmission shaft 132 is rotatably connected between the two operating surface brackets 131. The flap transmission bracket 133 is fixedly connected between the first flap transmission shaft 132 and the flap 11. When the first flap transmission shaft 132 rotates, it drives the flap 11 to rotate through the flap transmission bracket 133.

[0042] Reference Figure 4 and Figure 5Specifically, one end of the flap transmission bracket 133 is connected to a flap tension spring 134, and the other end of the flap tension spring 134 is connected to the operation surface bracket 131, so that when the flap transmission bracket 133 is not subjected to other external forces, the flap 11 is in the maximum open state under the action of the flap tension spring 134. At the same time, a brush tension spring 135 is also connected between the brush roller 121 and the operation surface bracket 131, so that when the brush roller 121 is not subjected to other external forces, the brush 122 is in the maximum open state.

[0043] Reference Figure 6 and Figure 7 Preferably, the brake transmission component includes a brush roller swing arm 136, a flap transmission shaft swing arm 137 and a brush power pressure plate 138. The brush roller swing arm 136 is fixed to one end of the brush roller 121, the flap transmission shaft swing arm 137 is fixed to one end of the first flap transmission shaft 132, the brush power pressure plate 138 extends in the horizontal direction, and a power slide 139 is provided on the upper surface of the brush power pressure plate 138. The end of the brush roller swing arm 136 away from the brush roller 121 slides against the groove wall of the power slide 139, and the end of the flap transmission shaft swing arm 137 away from the first flap transmission shaft 132 slides against the groove wall of the power slide 139. The brake drive component 15 is used to drive the brush power pressure plate 138 to make an arc motion, so that the brush roller swing arm 136 and the flap transmission shaft swing arm 137 swing in opposite directions, thereby adjusting the gap size of the paper deceleration gap 14.

[0044] Optionally, the brake drive component 15 can be an eccentric rocker arm component, and the rocker arm of the eccentric rocker arm component is connected to the brush power pressure plate 138. When the rocker arm of the eccentric rocker arm component rotates, it can drive the brush power pressure plate 138 to move in a circular trajectory, thereby adjusting the gap size of the paper deceleration gap 14. The eccentric rocker arm component can be driven by some transmission components outside the device, so that the gap size of the paper deceleration gap 14 can be adjusted outside the device.

[0045] Reference Figure 3 and Figure 4 Furthermore, the paper collection mechanism also includes a side plate 16, an operating surface bracket 131 is slidably connected to the side plate 16 along the paper conveying direction, a first rack 17 is fixedly connected to the inner side of the side plate 16, a first gear 18 is fixed to the end of the first flap transmission shaft 132, the first rack 17 and the first gear 18 are meshed, and when the gap of the paper deceleration gap 14 becomes smaller, the flap 11 and the brush 122 move a distance along the paper conveying direction. This design makes it possible to avoid paper jams or blockages caused by too small a gap when adjusting the gap size of the paper deceleration gap 14, thereby ensuring that the paper passes smoothly through the deceleration gap and improving the working stability and reliability of the paper collection mechanism. At the same time, this adjustable structure can also flexibly adapt to the processing of paper of different thicknesses or materials, further improving the scope of application and work efficiency of the equipment.

[0046] In addition, a brush position adjustment mechanism 19 can be set on the side of the side panel 16. The brush position adjustment mechanism 19 can use a gear rack mechanism to adjust the position of the operating surface bracket 131 in the paper conveying direction, thereby adjusting the position of the brush 122 and the flap 11 to improve its applicability.

[0047] Reference Figure 3 In another preferred embodiment, the upper surface of the flap 11 is provided with a suction hole 111, and a plurality of the suction holes 111 are arranged at equal intervals in the longitudinal and transverse directions. The suction holes 111 are located on the feeding side of the paper deceleration gap 14. When the paper passes through the paper deceleration gap 14, the suction holes 111 can absorb the dust scraped from the upper surface of the paper. Optionally, the air outlet end of the suction hole 111 can be connected to a suction pipe and a negative pressure suction system. Further, a sensor can be arranged near the flap 11. After the sensor detects that the paper passes through the paper deceleration gap 14, the negative pressure suction system performs a suction, and then stops suction. The next round of suction is performed after the next sheet of paper has passed completely, so as to avoid suction affecting the normal transportation of the paper. Through the above scheme, the brush 122 can decelerate the paper on the one hand, and clean the dust and other impurities on the upper surface of the paper on the other hand, and then recycle them through the suction hole 111, which can ensure the cleanliness of the paper and reduce the influence of dust and other impurities on the quality of the paper.

The shape of the receiving paperboard 2 can be rectangular or trapezoidal to accommodate paper of different specifications. The surface of the receiving paperboard 2 can be provided with an anti-slip texture to increase the friction of the paper and prevent the paper from sliding.

[0050] Optionally, the paper collecting plate 2 may be a belt-type paper collecting plate 2, that is, a belt is used as the paper collecting plate 2, and after the papers on the paper collecting plate 2 are stacked to a certain extent, the stacked papers are conveyed out by the belt-type paper collecting plate 2. Specifically, the position of the belt-type paper collecting plate 2 can be adjusted so that the belt-type paper collecting plate 2 can be moved away, and the papers fall from the stacking position of the belt-type paper collecting plate 2 onto the conveying plate, and the papers are conveyed out by the conveying plate.

[0051] Specifically, the paper lifting device 3 is used to release the paper conveyed by the paper gripper row (not shown in the figure) onto the receiving board 2. The paper lifting device 3 is generally used in conjunction with the paper gripper row to realize the conveying and separation of paper. In this application, the specific structure of the paper lifting device 3 is the prior art and will not be described in detail here.

[0052] Reference Figure 4 In a preferred embodiment, the blowing device 4 further includes a blowing support rod 42, a blowing slider 43 and a slider adjustment assembly 44. The blowing pipe 41 is located above the approximate center of the paper receiving paperboard 2. In this embodiment, the blowing pipe 41 extends perpendicular to the paper conveying direction, and the gas blown out from the air outlet is sprayed toward the center of the upper surface of the paper, so that the paper forms a state of being low in the middle and high on both sides during the falling process, thereby reducing the occurrence of the side edges of the paper being rolled up and bent during the falling process, and improving the flatness of the paper stacking.

[0053] At the same time, the blowing support rod 42 extends along the conveying direction of the paper, the blowing slider 43 is slidably connected to the blowing support rod 42, the blowing pipe 41 is installed on the blowing slider 43, and the slider adjustment assembly 44 is used to adjust the position of the blowing slider 43 on the blowing support rod 42, which can be flexibly adjusted according to the actual width and thickness of the paper.

[0054] Optionally, the slider adjustment component 44 may be a synchronous belt drive component (the synchronous belt is hidden in the figure), the synchronous belt of the synchronous belt drive component is connected to the air blowing slider 43, and the synchronous belt drive is driven by operating the synchronous belt drive component, that is, the position of the air blowing slider 43 can be adjusted, and then the position of the air blowing pipe 41 can be adjusted. Furthermore, the operating end of the synchronous belt drive component can be extended to the outside of the equipment for easy operation by personnel.

[0055] Reference Figure 2 and Figure 8 The paper aligning device 5 is arranged on the peripheral side of the upper surface of the receiving paperboard 2, and is used to reciprocally abut the peripheral side edges of the papers on the receiving paperboard 2 to align the stacked papers.

The paper aligning transmission assembly 55 is used to drive the left paper aligning frame 53 and the right paper aligning frame 54 to perform linear reciprocating motion, and at the same time drive the front paper aligning frame 51 and the rear paper aligning frame 52 to perform circular arc reciprocating motion, so that the front paper aligning frame 51 and the rear paper aligning frame 52 have a downward pressing action during the reciprocating motion, so that the paper stacking is more flat and compact.

The rotation axis of the paper aligning swing arm 551 is perpendicular to the paper conveying direction. The paper aligning swing arm 551 swings back and forth. The front and rear paper aligning transmission plates 552 are fixed to the ends of the paper aligning swing arm 551. The front and rear paper aligning transmission plates 552 are provided in two pieces and the same transmission shaft is connected between the two front and rear paper aligning transmission plates 552. The front paper aligning frame 51 and the rear paper aligning frame 52 are respectively fixed to the two front and rear paper aligning transmission plates 552, so as to achieve the relative approach or distance between the front and rear paper aligning frame 51 and the rear paper aligning frame 52 by driving the two front and rear paper aligning transmission plates 552 to move relative to each other.

[0058] The cam driving mechanism 56 can be used to drive the paper aligning swing arm 551 to swing. At this time, a tension spring can be set between the paper aligning swing arm 551 and the side plate (not shown in the figure), and then used in conjunction with the cam driving mechanism 56 to achieve reciprocating swing of the paper aligning swing arm 551.

[0059] At the same time, the sides of the front and rear paper aligning transmission plates 552 are provided with inclined blocks 555, the guide sleeve 553 is fixed to the side plate 16 and extends perpendicular to the paper conveying direction, the guide rail seat 554 is slidably connected to the guide sleeve 553, and a guide spring (not shown) is provided between the guide sleeve 553 and the guide rail seat 554, and the guide spring has elastic potential energy to push the guide seat toward the center of the paper receiving paper board 2; the left paper aligning frame 53 and the right paper aligning frame 54 are fixed to the guide rail seat 554, and the guide rail seat 554 is provided with a paper aligning transmission roller 556, The paper aligning transmission roller 556 can abut against the inclined surface of the inclined block 555 to make the guide rail seat 554 reciprocate along the guide sleeve 553. Optionally, the left paper aligning rack 53 and the right paper aligning rack 54 are respectively connected with an adjusting rod 557, and the adjusting rod 557 is slidingly connected to the guide rail seat 554, and a locking piece is provided between the adjusting rod 557 and the guide rail seat 554 for locking. Therefore, the width between the left paper aligning rack 53 and the right paper aligning rack 54 can be adjusted by the adjusting rod 557, thereby further improving its scope of application.

[0060] The present application uses the same cam drive mechanism 56 to synchronously drive the front and rear paper aligning components and the left and right paper aligning components to move, which not only improves the overall flatness of the paper stack, but also reduces subsequent processing problems caused by misalignment, thereby improving production efficiency and product quality.

[0061] The implementation principle of this embodiment is as follows: the paper is braked by the brake brush device 1 to slow down the conveying speed of the paper and reduce the instability of the paper during the transmission process. The paper collection board 2 supports the paper and provides paper for stacking, thereby improving the flatness of the paper. The paper picking device 3 releases the paper from the paper gripping teeth row to ensure the smooth transfer of the paper. The air blowing device 4 blows air to the center of the upper surface of the paper through the air blowing pipe 41, so that the center height of the paper is lower than the peripheral height when the paper falls, thereby avoiding the tilting of the paper during the falling process. The paper aligning device 5 realizes automatic alignment of the paper through the coordinated work of the front and rear paper aligning components and the left and right paper aligning components, thereby improving the quality and efficiency of paper stacking. These designs jointly solve the problems of tilting and offsetting that are prone to occur during paper stacking in traditional paper collection mechanisms, thereby improving product quality and production efficiency.

[0062] The present application also discloses a die-cutting machine, which significantly improves the automation and production efficiency of paper processing by integrating the above-mentioned efficient paper collection mechanism. In particular, when processing large quantities and multiple varieties of paper, it can maintain high stability and consistency, and is suitable for various industrial production and printing and packaging fields.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
