Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a paper feeding machine. Background Art

[0002] In the paper printing industry, raw paper must be cut to size before printing. This requires a series of processes, including paper picking, cutting, and unloading. Currently, factories primarily utilize a paper picker, a paper cutter, and a paper unloader to form a complete production line. During paper picking, the picker grabs the appropriate number of sheets from the stack, according to the paper cutter's stack height limit, and then transfers the sheets to the cutter's worktable.

[0003] Traditional paper cutters generally include: a base module, a paper loading module, and a paper clamping module. During operation, the paper clamping module first lifts one end of the paper through the lifting cardboard, making the paper pile loose in the vertical direction. Then, the multiple paper picking paddles in the paper clamping module rotate horizontally in turn, and the action of each paper picking paddle is set with a delay in turn. For example, when the previous paper picking paddle rotates 90° and is fully inserted into one of the gaps and stretches it open, at this time, the next paper picking paddle rotates 60° and can be inserted into the gap stretched by the previous paper picking paddle. Through this design, it is ensured that each paper picking paddle can be inserted into the same gap. After all the paper picking paddles are inserted into the same gap, the paper pressing cardboard of the paper clamping module descends, and the paper pressing cardboard and paper picking paddles clamp the paper pile in place. Next, the paper carrier in the paper loading module is horizontally inserted from under the paper pick-up paddle into the gap where the paper pick-up paddle is located until the paper pile is completely accommodated by the paper carrier. Finally, the paper clamping module and the paper carrier move horizontally synchronously to deliver the paper pile to the workbench of the paper cutter. The disadvantage of this traditional paper cutter is that space for rotation needs to be reserved between two adjacent paper pick-up paddles, that is, these paper pick-up paddles are set at intervals. When applied to hard paper, there is no problem, but when applied to soft paper, there is still a risk that two adjacent paper pick-up paddles will be inserted into different gaps. Because the hardness of the paper is low, the paper in the gap between the two adjacent paper pick-up paddles is likely to sag, causing the gap to be unable to support the gap, making it impossible to ensure that the next paper pick-up paddle enters the same gap, which ultimately leads to paper clamping failure and low paper pickup reliability. Utility Model Content

[0004] Based on this, the utility model provides a paper picker, which uses a paper picker with a triangular tip structure to avoid the problem that traditional multiple rotating picks cannot ensure that they are inserted into the same gap, and adopts an inclined wedge structure to achieve linkage, effectively compressing the lateral space occupied, maintaining the compactness of the structure, improving the success rate of paper clamping, and enhancing the reliability of paper picking.

[0005] A paper dispensing machine, comprising:

[0006] Base module;

[0007] a paper carrier module connected to the base module; and

[0008] The paper clamping module is connected to the base module; the paper clamping module includes: a second crossbeam connected to the base module, a paper clamping unit connected to the second crossbeam, and a paper clamping transverse movement driver connected to the paper clamping unit; the paper clamping unit includes: a transverse movement slide slidably connected to the second crossbeam, a paper picking paddle slidably connected to the transverse movement slide, a driving block slidably connected to the transverse movement slide, a paper insertion lifting driver connected to the driving block, a reset spring connected between the paper picking paddle and the transverse movement slide, an outer cover connected to the transverse movement slide, a paper clamping pressure plate slidably connected to the outer cover, and a paper clamping lifting driver connected to the paper clamping pressure plate; the paper clamping transverse movement driver is used to drive the transverse movement slide to move linearly along the second crossbeam; the front end of the paper picking paddle is a triangular tip structure, and the paper picking paddle is provided with a first inclined wedge surface; the driving block is provided with a second inclined wedge surface matching the first inclined wedge surface; the paper insertion lifting driver is used to drive the driving block to descend so as to force the paper picking paddle to be inserted into the gap of the paper pile; the reset spring is used to drive the paper picking paddle to reset; the outer cover is provided with a lifting paper board; the paper clamping driver is used to drive the paper clamping pressure plate to move up and down.

[0009] In the aforementioned paper picker, when paper needs to be clamped, the transverse drive drives the transverse slide to the storage area of the paper pile, so that the lifting plate on the outer cover rests against the side of the paper pile. Next, the base module drives the paper loading module and the paper clamping module to rise synchronously, raising the lifting plate to loosen the paper pile vertically. The paper insertion lift drive then drives the drive block downward, using the wedge structure to force the paper pick paddle forward. Because the paper pick paddle has a triangular tip structure, the tip of the paper pick paddle is first inserted into one of the gaps in the paper pile, and the subsequent areas of the paper pick paddle are then gradually inserted into the same gap along the tip. When the paper pick paddle has been inserted to the required depth for paper removal, the paper clamping lift drive drives the paper clamping plate downward, so that the paper clamping plate and the paper pick paddle jointly clamp the paper pile of a preset thickness. Through the above design, the paper picking pick with a triangular tip structure is used to avoid the problem that traditional multiple rotating picks cannot ensure that they are inserted into the same gap, and the inclined wedge structure is used to achieve linkage, effectively compressing the lateral space occupied, maintaining the compactness of the structure, improving the success rate of paper clamping, and enhancing the reliability of paper picking.

[0011] In one embodiment, the paper loading module includes: a first beam connected to the base module, a paper loading platform slidably connected to the first beam, a paper loading transverse movement driver connected to the paper loading platform, a paper locking pressure plate slidably connected to the paper loading platform, and a paper locking lifting driver connected to the paper locking pressure plate; the paper loading transverse movement driver is used to drive the paper loading platform to move linearly along the first beam; the paper locking lifting driver is used to drive the paper locking pressure plate to move up and down.

[0012] In one embodiment, the paper carrier is an air-floating platform, which can reduce the friction coefficient between the supporting surface of the paper carrier and the bottom surface of the paper pile, thereby improving the smoothness of the sliding of the paper pile on the paper carrier.

[0013] In one embodiment, the front end of the paper carrier is a triangular tip structure, which allows the front end of the paper carrier to be smoothly inserted into the same gap of the paper pile along the ejection direction of the paper picking paddle.

[0014] In one embodiment, a roller is provided at the bottom of the transverse slide, and a first chute is provided on the supporting surface of the paper platform for the roller to travel.

[0015] In one embodiment, an L-shaped support portion is provided at the bottom of the transverse slide; the paper pick-up paddle is slidably connected to the support portion. The L-shaped support portion can provide stable support for the paper pick-up paddle and improve the reliability of the paper clamping action.

[0041] like Figures 1 to 13 As shown, it is a paper dispenser 100 according to an embodiment of the present invention.

[0042] like Figure 1 and Figure 2 As shown, the paper dispenser 100 comprises a base module 10, a paper carrier module 20 connected to the base module 10, and a paper clamping module 30 connected to the base module 10. The base module 10 drives the paper carrier module 20 and the paper clamping module 30 to move synchronously upward and downward, and serves as the base of the device. The paper carrier module 20 is used to carry a stack of paper. The paper clamping module 30 is used to pick up a predetermined amount of paper from the stack.

[0043] Below, combined Figures 1 to 13 , the above-mentioned paper dispenser 100 is further explained.

[0044] like Figure 2As shown, in this embodiment, the base module 10 includes a frame 11, a lift platform 12 slidably connected to the frame 11, and a paper pickup lift actuator 13 connected to the lift platform 12. The lift platform 12 is used to mount the paper loading module 20 and the paper clamping module 30. The paper pickup lift actuator 13 is used to drive the lift platform 12 to move the paper loading module 20 and the paper clamping module 30.

[0045] like Figure 3 As shown, in this embodiment, the paper loading module 20 includes: a first crossbeam 21 connected to the base module 10, a paper loading platform 22 slidably connected to the first crossbeam 21, a paper loading transverse movement driver 23 connected to the paper loading platform 22, a paper locking plate 24 slidably connected to the paper loading platform 22, and a paper locking lift driver 25 connected to the paper locking plate 24. The paper loading transverse movement driver 23 is used to drive the paper loading platform 22 to move linearly along the first crossbeam 21. The paper locking lift driver 25 is used to drive the paper locking plate 24 to move up and down to press the paper stack against the paper loading platform 22.

[0046] Furthermore, in this embodiment, the paper carrier 22 is an air-floating platform, which can reduce the friction coefficient between the supporting surface of the paper carrier 22 and the bottom surface of the paper pile, thereby improving the smoothness of the paper pile sliding on the paper carrier 22.

[0047] like Figure 5 As shown, in this embodiment, the paper clamping module 30 includes: a second crossbeam 31 connected to the base module 10, a paper clamping unit 32 connected to the second crossbeam 31, and a paper clamping transverse movement driver 33 connected to the paper clamping unit 32. The paper clamping transverse movement driver 33 is used to drive the paper clamping unit 32 to move linearly along the second crossbeam 31, and the paper clamping unit 32 is used to clamp the paper stack.

[0048] like Figures 6 to 9 As shown, in this embodiment, the paper clamping unit 32 includes: a transverse slide 321 slidably connected to the second crossbeam 31; a paper pick-up paddle 322 slidably connected to the transverse slide 321; a drive block 323 slidably connected to the transverse slide 321; a paper insertion lift actuator 324 connected to the drive block 323; a return spring 325 connected between the paper pick-up paddle 322 and the transverse slide 321; an outer cover 326 connected to the transverse slide 321; a paper clamping plate 327 slidably connected to the outer cover 326; and a paper clamping lift actuator 328 connected to the paper clamping plate 327. Driven by the transverse drive, the transverse slide 321 slides linearly along the second crossbeam 31. The paper insertion lift actuator 324 drives the drive block 323 downward to force the paper pick-up paddle 322 into the gap between the paper stack. The return spring 325 resets the paper pick-up paddle 322.

[0049] like Figure 9As shown, in this embodiment, an L-shaped support portion 3211 is provided at the bottom of the transverse slide 321. The paper pick-up paddle 322 is slidably connected to the support portion 3211. The L-shaped support portion 3211 can provide stable support for the paper pick-up paddle 322, thereby improving the reliability of the paper clamping action.

[0050] In addition, in this embodiment, Figure 7 As shown, the bottom of the transverse sliding seat 321 is provided with a roller 3212. Figure 4 As shown, the supporting surface of the paper carrier 22 is provided with a first chute 221 for the roller 3212 to move. The roller 3212 and the first chute 221 cooperate to allow the transverse slide 321 to roll on the paper carrier 22, so that the two can be as close as possible, which facilitates the paper carrier 22 to be inserted into the same gap as the paper pick 322.

[0051] Further, if Figure 10 As shown, the front end of the paper picking pick 322 is a triangular tip structure, and the paper picking pick 322 is provided with a first inclined wedge surface 3221. Figure 8 and Figure 9 As shown, the driving block 323 is provided with a second inclined wedge surface 3231 matching the first inclined wedge surface 3221. The outer cover 326 is provided with a lifting paper board 3261. The paper clamping driver is used to drive the paper clamping plate 327 to move up and down.

[0052] Based on the design of the front end of the paper picking pick 322 being a triangular tip structure, as shown in FIG. Figure 4 As shown, in this embodiment, the front end of the paper carrier 22 may also be a triangular tip structure. The triangular tip structure allows the front end of the paper carrier 22 to be smoothly inserted into the same gap of the paper stack along the ejection direction of the paper pick 322 (see Figure 12 ).

[0053] like Figure 11 As shown, in this embodiment, the outer cover 326 is provided with a second slide 3262. At the same time, the paper clamping plate 327 is provided with a connecting piece connected to the paper clamping lifting driver 328. The connecting piece is slidably connected to the second slide 3262. The second slide 3262 can limit the movement trajectory of the paper clamping plate 327, improving the accuracy and reliability of the lifting action of the paper clamping plate 327.

[0054] Brief description of working principle:

[0055] When paper needs to be clamped, the transverse drive drives the transverse slide 321 to the paper stack, allowing the lift plate 3261 on the outer cover 326 to rest against the side of the paper stack. The base module 10 then simultaneously raises the paper loading module 20 and the paper clamping module 30, raising the lift plate 3261 to loosen the paper stack vertically.

[0056] Next, the paper insertion lift driver 324 drives the drive block 323 downward, forcing the paper pick paddle 322 forward using the wedge structure. Because the paper pick paddle 322 has a triangular tip, the tip of the paddle 322 first inserts into one of the gaps in the paper stack, and the remaining areas of the paddle 322 gradually insert into the same gap, following the tip. When the paddle 322 reaches the required depth for paper removal, the clamping lift driver 328 drives the clamping plate 327 downward, allowing the clamping plate 327 and the paddle 322 to jointly clamp the paper stack to a predetermined thickness.

[0057] Then, if Figure 12 As shown, the paper carrier 22 moves forward to the paper pick 322 to start inserting into the same gap of the paper pile. Figure 13 As shown, until all the paper stacks are accommodated on the paper loading platform 22.

[0058] Finally, the paper loading platform 22 and the paper clamping unit 32 move backward synchronously (if a paper locking structure is provided on the paper loading platform 22, such as the above-mentioned paper locking pressure plate 24 and paper locking lifting drive, the paper clamping unit 32 can release the paper stack or keep the paper stack clamped) until the paper stack is delivered to the workbench of the paper cutter.

[0059] The paper picker 100 uses a paper picker 322 with a triangular tip structure to avoid the problem that multiple conventional rotating picks cannot be inserted into the same gap, and adopts an inclined wedge structure to achieve linkage (for example, Figure 8 As shown, the vertical driving force is converted into the horizontal driving force, so that the paper insertion lifting driver 324 can be set vertically to reduce the horizontal space occupation), effectively compressing the horizontal space occupation, maintaining the compactness of the structure, improving the success rate of paper clamping, and improving the reliability of paper removal.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments merely represent preferred implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
