Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated board printing, and more specifically, particularly relates to a material discharging structure of a corrugated board printing and die-cutting machine. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper and one layer of cardboard, and has high mechanical strength.

[0003] The existing corrugated cardboard printing and die-cutting machine transmits the corrugated cardboard after printing and die-cutting from the paper outlet, and the transmitted corrugated cardboard is placed on the conveyor belt and transmitted to the paper receiving frame through the conveyor belt. In order to increase the collection and storage capacity of the corrugated cardboard by the paper receiving frame, the user increases the capacity height inside the paper receiving frame by raising the upward inclination angle of the conveyor belt, so that the corrugated cardboard can be transmitted through the inclined conveyor belt and accurately fall into the paper receiving frame from the end of the high conveyor belt, so as to achieve the unified collection of a large number of corrugated cardboards. However, due to the excessively fast paper discharge speed of the paper outlet, a plurality of corrugated cardboards overlap and stack on the conveyor belt. The overlapped and stacked corrugated cardboards are transmitted through the conveyor belt. Because the conveyor belt is inclined, the adhesion between the overlapped and stacked corrugated cardboards is insufficient, resulting in that during the transportation process, the remaining corrugated cardboards except the bottommost corrugated cardboard slide downward, causing the position of the corrugated cardboard to shift, thereby reducing the production efficiency of the printing and die-cutting machine.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a discharge structure of a corrugated cardboard printing and die-cutting machine is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a material discharge structure of a corrugated cardboard printing and die-cutting machine to solve the problem that due to the excessively fast paper discharge speed of the paper outlet, multiple sheets of corrugated cardboard are overlapped and stacked on a conveyor belt, and the overlapped and stacked corrugated cardboards are transported by the conveyor belt. Because the conveyor belt is set at an angle, the adhesion between the overlapped and stacked corrugated cardboards is insufficient, resulting in the remaining corrugated cardboards except the bottom corrugated cardboard sliding downward during transportation, causing the position of the corrugated cardboards to shift.

[0006] The purpose and function of the discharging structure of the corrugated board printing and die-cutting machine of the utility model are achieved by the following specific technical means:

[0007] A discharge structure of a corrugated cardboard printing and die-cutting machine, comprising a printing and die-cutting machine body and a conveying mechanism, wherein the conveying mechanism is located in front of the printing and die-cutting machine body, and supports are provided on both sides of the top of the conveying mechanism, and a stopper is provided between the two supports, and the spacing between the stopper and the conveying belt in the conveying mechanism is greater than the thickness of one corrugated cardboard but not more than the thickness of two corrugated cardboards;

[0008] Fixed seats are provided on both sides of the top of the conveying mechanism, and moving blocks are slidably inserted into the two fixed seats. One end of the moving block is connected to an arc guide plate, and the arc guide plate is located on the conveyor belt. A locking mechanism is provided between the fixed seat and the arc guide plate, and the conveying mechanism is driven by a motor.

[0009] Furthermore, the locking mechanism includes an adjusting block arranged on the top of the fixed seat, a connecting port penetrating the adjusting block is opened on the top of the fixed seat, a fixed block is slidably arranged in the connecting port, a rotating shaft is passed through the adjusting block, a wrench is sleeved on the rotating shaft, and one end of the wrench is abutted against the fixed block.

[0010] Furthermore, the conveying mechanism is also provided with a lifting assembly, which includes a multi-position cylinder, which is installed on both sides of the conveying mechanism, and the two ends of the block are respectively located in two supports, and sliding grooves are provided on both sides of the inside of the two supports. The two sides of the block are slidably connected with the sliding grooves through sliders, and a limiting groove is provided on the side wall of the support, and a connecting block is passed through the limiting groove. The block is connected to the piston rod of the multi-position cylinder through the connecting block.

[0011] Furthermore, the shape of the arc guide plate is L-shaped, and a paper receiving frame is provided on one side of the conveying mechanism.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting the stopper, the spacing between the stopper and the conveyor belt is greater than the thickness of one corrugated cardboard but not more than the thickness of two corrugated cardboards. When the conveyor belt rotates forward, multiple overlapping and stacked corrugated cardboards on the surface of the conveyor belt contact the stopper, and the stopper blocks the corrugated cardboards exceeding the set spacing, while the corrugated cardboards passing the set spacing continue to be conveyed forward during the rotation of the conveyor belt, and the blocked conveying plate falls on the conveyor belt, and the stopper blocks the overlapping and stacked corrugated cardboards again, thereby preventing the overlapping and stacked corrugated cardboards from sliding downward during transportation on the inclined conveyor belt, preventing the sliding corrugated cardboards from being displaced, and improving the production efficiency of the printing and die-cutting machine.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 5 As shown:

[0026] The utility model provides a material discharging structure of a corrugated cardboard printing and die-cutting machine, comprising a printing and die-cutting machine body 1 and a conveying mechanism 2, wherein the conveying mechanism 2 is located in front of the printing and die-cutting machine body 1, and a paper receiving frame 3 is arranged in front of the conveying mechanism 2, and the conveying mechanism 2 is a plurality of conveying belt 14 units arranged in parallel, each unit comprising a driving roller, a redirecting roller, a supporting roller, a tensioning device and a conveying belt 14, wherein the roller is driven to rotate by a motor, and the friction between the roller and the belt is utilized to make the belt run continuously, and supports 4 are fixedly arranged on both sides of the top of the conveying mechanism 2, The support 4 is in a U-shape, and a stopper 5 is arranged between the two supports 4. The stopper 5 can be used to block the corrugated cardboard that exceeds the set spacing. Since the conveyor belt 14 in the conveying mechanism 2 is arranged obliquely, the spacing between the stopper 5 and the conveyor belt 14 in the conveying mechanism 2 is set to be greater than the thickness of one corrugated cardboard but not more than the thickness of two corrugated cardboards, thereby avoiding the phenomenon of paper jam when the overlapping and stacked corrugated cardboards pass through the set spacing, thereby improving the conveying efficiency. The conveyor belt 14 drives the overlapping and stacked multiple corrugated cardboards from the space below the stopper 5. When the stacked corrugated cardboards pass through the gap, the overlapping and stacked multiple corrugated cardboards contact the side wall of the block 5, and the block 5 blocks the corrugated cardboards that exceed the set gap to prevent them from continuing to overlap and stack. The corrugated cardboards that meet the set gap requirements can smoothly pass through the gap below the block 5 and continue to be transported forward along the predetermined route under the continuous drive of the conveyor belt 14. The corrugated cardboards blocked by the block 5 will naturally fall from the corrugated cardboards that meet the gap requirements under the block 5 due to the loss of support from the bottom corrugated cardboard, and fall back on the The corrugated cardboard that subsequently falls down on the conveyor belt 14 contacts the block 5 again under the drive of the conveyor belt 14, and the block 5 plays a role again to block the corrugated cardboard that exceeds the set spacing. This continuous process ensures that only the corrugated cardboard that meets the set spacing requirements can continue to move forward, thereby achieving effective separation of multiple overlapping and stacked corrugated cardboards, which helps multiple corrugated cardboards to be arranged neatly and move forward during the conveying process, and prevents multiple corrugated cardboards from overlapping and stacking, so that the corrugated cardboards slide down during the conveying process;

[0027] A fixed seat 10 is provided on both sides of the top of the conveying mechanism 2. The fixed seat 10 is located on one side of the support 4. A moving block 11 is slidably penetrated in the fixed seat 10. An arc guide plate 12 is provided at one end of the moving block 11. The arc guide plate 12 is located above the conveyor belt 14 and is relatively parallel to the conveyor belt 14. The shape of the arc guide plate 12 is "L" shaped. The setting of the arc guide plate 12 can guide and adjust the movement direction of the corrugated cardboard on the conveyor belt 14 to ensure that they move along a predetermined path. The adjustment block 131 set on the top of the fixed seat 10, the fixed The top of the fixed seat 10 is provided with a connection port 132 that penetrates the adjustment block 131, and a fixed block 135 is slidably arranged inside the connection port 132. A rotating shaft 133 is passed through the adjusting block 131, and a wrench 134 is sleeved on the rotating shaft 133. The bottom of the wrench 134 is in the shape of an eccentric wheel. One side of the fixed block 135 contacts with a protruding position at one end of the wrench 134, and the other side of the fixed block 135 contacts with the moving block 11. When the wrench 134 rotates around the rotating shaft 133 as the axis, the protruding position at one end of the wrench 134 is moved by the one side of the fixed block 135. The other side of the fixed block 135 abuts against the moving block 11, thereby achieving a locking and fixing effect. The user can adjust the position of the moving block 11 in the fixing seat 10 according to the length of the corrugated cardboard. The moving block 11 with the adjusted position is abutted against the fixed block 135 by rotating the wrench 134, and the protruding position of one end of the wrench 134 abuts against the fixed block 135, so that the other side of the fixed block 135 abuts against the moving block 11, so that the arc guide plate 12 with the adjusted position is locked and fixed in the fixed block 135, so that the arc guide plate 12 can be more flexibly adapted to different specifications. The arc guide plate 12 can guide the corrugated cardboard in the grid and stacked state, and prevent the arc guide plate 12 from moving when it is hit by the position-shifted corrugated cardboard. When the corrugated cardboard on the conveyor belt 14 is shifted, the arc guide plate 12 will exert a certain guiding effect on the position-shifted corrugated cardboard. The two arc guide plates 12 can guide the position-shifted corrugated cardboard to move along a predetermined path through the coordinated effect of the two arc guide plates 12, thereby ensuring that the corrugated cardboard is neatly arranged, avoiding the position shift of the corrugated cardboard, and further improving the production efficiency of the printing and die-cutting machine.

[0028] The conveying mechanism 2 is also provided with a lifting assembly 9, which includes a multi-position cylinder 92, which is installed on both sides of the conveying mechanism 2. Slide grooves 6 are provided on both sides of the two supports 4. Both sides of the stopper 5 are slidably connected to the slide grooves 6 through sliders 7. A limiting groove 8 is provided on the side wall of the support 4, and a connecting block 91 is provided in the limiting groove 8. The stopper 5 is connected to the piston rod of the multi-position cylinder 92 through the connecting block 91. The multi-position cylinder 92 is used as a power source. It is based on the mechanical principle of compressed air and can achieve multiple position stops. It is composed of two to five cylinders with different stroke lengths connected in series. By controlling the extension and retraction of different cylinders, the block can be accurately positioned at different heights. When the user needs to control the multi-position cylinder 92 according to corrugated cardboards of different thicknesses, two multi-position cylinders 92 are started at the same time, and the piston rods of the two multi-position cylinders 92 simultaneously drive the connecting block 91 to move upward in the limit groove 8, thereby driving the block 5 to slide up and down in the support 4 through the slider 7, and controlling and adjusting the distance between the block 5 and the conveyor belt 14, thereby further improving the production efficiency of the printing die-cutting machine; the multi-position cylinder 92 is a prior art and is not described in detail in the present utility model.

[0029] When using:

[0030] After printing and die-cutting, the corrugated cardboard is passed out from the paper outlet. Multiple sheets of corrugated cardboard are overlapped and stacked on the surface of the conveyor belt 14. The conveyor belt 14 drives the overlapped and stacked corrugated cardboard to move forward. When the overlapped and stacked corrugated cardboard passes through the gap between the baffle 5 and the conveyor belt 14, the overlapped and stacked corrugated cardboard contacts the side wall of the block 5. The block 5 blocks the corrugated cardboard that exceeds the set gap, while the corrugated cardboard that meets the gap requirement passes through the block 5 smoothly and continues to be conveyed forward driven by the conveyor belt 14. The corrugated cardboard blocked by the block 5 is The corrugated cardboard that loses the support of the bottom will fall back onto the conveyor belt 14. Driven by the conveyor belt 14, the fallen corrugated cardboard will contact the block 5 again. The block 5 will block the corrugated cardboard that exceeds the set spacing again. The two arc-shaped guide plates 12 adjust and guide the position of the corrugated cardboard on the conveyor belt 14 to allow it to move along a predetermined path. The neatly arranged corrugated cardboard is conveyed forward and then neatly falls into the paper receiving frame 3, which prevents the corrugated cardboard from sliding downward during the conveyance process, thereby causing position deviation, thereby improving the production efficiency of the printing and die-cutting machine.
