Description

Technical Field

[0001] This invention relates to the field of printing and conveying equipment technology, specifically to a multi-part document collation and coding conveying device. Background Technology

[0002] Existing multi-part document collation and coding equipment mainly includes a conveying device, a gripper, a coding device, a paper receiving table, and a control system. Each part of the document is conveyed to the gripper for collation by the conveying device. After collation, the document is conveyed to the coding device for coding. After coding, the document is stacked and recycled by the paper receiving table. The control system controls the coding device and the gripper to work.

[0003] However, existing conveying devices lack a flattening function for ticket pages, resulting in easily wrinkled ticket papers that can affect subsequent coding and positioning. Furthermore, wrinkled ticket papers can also reduce transmission efficiency. Therefore, we propose a multi-part ticket collation and coding conveying device to improve upon these shortcomings.

The relative width between the right guide frame and the left guide frame can be changed by adjusting the right guide frame to accommodate different widths of paper. Sliding wheels are provided on both sides of the sliding rod. The sliding wheels can move back and forth in the sliding groove to adjust the front and back position of the leveling device on the conveyor belt. After adjusting to the position, the sliding wheels can be locked with locking plates. It is simple and efficient. Attached Figure Description

[0038] Example:

[0039] Please see Figure 1-8 The present invention provides a technical solution for a multi-part invoice collation and coding conveying device: including a conveying device 1, which includes a conveyor belt 2, a leveling device 3, a guiding device 4 and a discharge leveling device 5;

[0040] A fixing frame 22 is symmetrically arranged on the left and right sides of the conveyor belt 2, and the fixing frame 22 is wrapped around the outside of the conveyor belt 2;

[0041] The front end of the conveyor belt 2 is equipped with a discharge leveling device 5, the rear end of the conveyor belt 2 is equipped with a guide device 4, and the middle of the conveyor belt 2 is equipped with a leveling device 3.

[0042] The discharge leveling device 5 includes two parallel extrusion rollers 52, with a discharge gap reserved between the extrusion rollers 52, and the discharge gap corresponds to the top surface of the conveyor belt 2.

[0043] Fixed plates 53 are connected to the left and right sides of the upper and lower extrusion rollers 52 near the fixed frame 22. The fixed plates 53 are rotatably connected to the extrusion rollers 52, and a limit ring is provided at the connection between the extrusion rollers 52 and the fixed plates 53.

[0044] A drive motor 21 is installed on the left front end of the fixed frame 22. The drive motor 21 is connected to the conveyor belt 2 inward. A drive wheel 23 is sleeved on the right side of the drive motor 21.

[0045] A pulley 51 is provided at the left end of the lower extrusion roller 52. The pulley 51 is parallel to the drive wheel 23 and is connected to the drive wheel 23 by a transmission belt.

[0046] The upper extrusion roller 52 is a driven roller;

[0047] The guiding device 4 includes a guide plate 41 and a guide frame 42. The guide plate 41 and the guide frame 42 are symmetrical on the left and right sides. The opposite sides of the left and right guide frames 42 are provided with front and rear guide grooves. There are four guide plates 41, which are symmetrically arranged in pairs at the front and rear ends of the conveyor belt 2. The guide plate 41 is a crescent-shaped arc plate and is connected to the front and rear ends of the guide frame 42 and is parallel to the guide frame 42.

[0048] The guide plate 41 is hollow, and a guide wheel is rotatably provided in the middle of the guide plate 41. The guide wheel is arranged along the arc of the guide plate 41.

[0049] The right guide frame 42 is fixedly connected to the guide plates 41 at the front and rear ends to form a whole, and is slidably set in the left fixed frame 22;

[0050] Three adjustment slots 43 are provided on the right side of the left fixed frame 22. Each of the three adjustment slots 43 is equipped with a locking bolt 44. The three locking bolts 44 are screwed downwards to the right guide frame 42. When unlocking, the locking bolts 44 move left and right in the adjustment slots 43.

[0051] Locking bolt 44 is a ring handle bolt;

[0052] A leveling device 3 is slidably installed on the top of the conveyor belt 2. The leveling device 3 includes three horizontally arranged extrusion rods 32 and two symmetrically arranged sliding rods 33. The extrusion rods 32 and the sliding rods 33 form a loop frame.

[0053] Leveling wheels 36 are equidistantly arranged at the bottom of the three extrusion rods 32. The leveling wheels 36 are fixed to the extrusion rods 32 by bolts, and the bottom of the wheel surface of the leveling wheels 36 abuts against the top surface of the conveyor belt 2.

[0054] Sliding frames 31 are fixed to the top of opposite sides of the fixed frames 22 on both the left and right sides, and sliding grooves are opened on opposite sides of the sliding frames 31 on both the left and right sides.

[0055] Two sliding rods 33 are respectively close to the left and right sliding frames 31. Sliding wheels 39 are equally spaced on the side of the left and right sliding rods 33 that are close to the sliding frame 31. The sliding wheels 39 slide against the sliding groove of the sliding frame 33.

[0056] A fixing frame is installed between the sliding wheel 39 and the sliding rod 33, and a locking piece 38 is slidably installed on the fixing frame;

[0057] Both ends of the extrusion rod 32 are movably inserted into the sliding rod 33, and adjustment holes are provided at the joints between the sliding rod 33 and the extrusion rod 32. Adjustment bolts 37 are screwed into the adjustment holes, and knob caps 34 are provided on the top of the adjustment bolts 37.

[0058] The knob cap 34 is rotatably mounted on the top surface of the slide rod 33. The adjusting bolt 37 includes an upper smooth section and a lower threaded section. The lower threaded section of the adjusting bolt 37 is screwed downwards onto the pressing rod 32, and the upper smooth end of the adjusting bolt 37 is rotatably inserted into the slide rod 33.

[0059] A leveling rod 35 is horizontally arranged at the front end of the leveling device 3. The leveling rod 35 is inclined and its bottom extends to the top surface of the conveyor belt 2.

[0060] Furthermore, in this solution, the paper tickets are conveyed from back to front along the conveyor belt 2. First, they pass through the guide plate 41 at the rear end. The openings of the two guide plates 41 expand outward and gradually contract inward as the paper tickets move forward, guiding the paper tickets into the guide frame 42.

[0061] Meanwhile, a guide wheel is provided inside the guide plate 41. When the ticket paper comes into contact with the guide wheel, the wheel slides, reducing the friction between the guide plate 41 and the ticket paper.

[0062] Then, the paper is guided to the guide frame 42 and continues forward along the guide groove inside the guide frame 42. The guide groove corresponds to the top surface of the conveyor belt 2, so that the two sides of the paper are engaged in the guide groove. The guide groove can keep the stability during conveying by limiting the paper, and can also align and flatten the two sides of the paper.

[0063] Furthermore, as the conveyor belt 2 continues to convey forward, the paper passes through the leveling device 3. The bottom of the leveling device 3 is equipped with leveling wheels 36. Several leveling wheels 36 are arranged in sequence on the width of the conveyor belt 2 to flatten the paper, making the paper that is conveyed out flatter and easier to find the printing point.

[0064] The leveling rollers 36 are all bolted to the extrusion rods 32, which can be quickly replaced when damaged. They can also be replaced with leveling rollers 36 of different wheel widths to achieve better extrusion and leveling effect.

[0065] Furthermore, the relative position of the extrusion rod 32 and the top surface of the conveyor belt 2 is adjustable. When adjusting, turning the knob cap 34 will drive the adjusting bolt 37 to rotate. The threaded section at the bottom of the adjusting bolt 37 is screwed to the extrusion rod 32. By rotating the screwed section, the height of the extrusion rod 32 in the adjusting hole is adjusted, which in turn adjusts the relative distance between the leveling wheel 36 and the top surface of the conveyor belt 2.

[0066] During adjustment, the upper smooth section of the adjusting bolt 37 can rotate instead of moving up and down like the threaded section, so that the knob cap 34 can always remain in contact with the sliding rod 33 and remain stable;

[0067] Furthermore, sliding wheels 39 are provided on both sides of the sliding rod 33. The sliding wheels 39 can move back and forth in the sliding groove to adjust the front and rear position of the leveling device 3 on the conveyor belt 2. After adjusting to the position, the sliding wheels 39 can be locked with locking plates 38.

[0068] The locking plate 38 is slidably mounted on the fixed frame. When locking, the locking plate 38 is pushed down and slides along the arc towards the wheel surface of the sliding wheel 39, and abuts against the wheel surface of the sliding wheel 39. Through the friction between the locking plate 38 and the sliding wheel 39, the sliding wheel 39 is limited and fixed, which is very convenient. The sliding part of the locking plate 38 uses damping sliding. The damper makes the sliding have a certain resistance, which can prevent the locking plate 38 from rebounding.

[0069] Furthermore, the guide frame 42 on the right side is slidably set inside the fixed frame 22 and can be adjusted inward. The sliding distance is the length of the adjustment groove 43. After sliding to the position, it is screwed downward by the locking bolt 44. The locking bolt 43 is positioned and screwed onto the guide frame 42. When unlocking, it can slide to the left synchronously with the right guide frame 42 in the adjustment groove 43. A locking washer is fitted on the locking bolt 44. When the locking bolt 44 is screwed downward, it squeezes the locking washer. The locking washer is squeezed onto the surface of the fixed frame 22, and locking is completed by squeezing and fixing.

[0070] The relative width between the right guide frame 42 and the left guide frame 42 can be changed by adjusting the right guide frame 42 to accommodate different widths of paper, which is simple and efficient.

[0071] Furthermore, a discharge leveling device 5 is provided at the front end of the conveyor belt 2. When the paper tickets are output forward through the conveyor belt 2, they are discharged forward under the pressure of the extrusion roller 52. The paper tickets can be finally extruded and leveled during discharge to keep them flat. At the same time, a smoothing rod 35 is provided at the front end of the leveling device 3. The smoothing rod 35 abuts against the top surface of the conveyor belt 2. When the paper tickets pass by, they are smoothed on the surface in sequence to flatten the bulges on the paper. The smoothing effect is very efficient.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics.
