Description

Technical Field

[0001] This invention relates to the field of paper cutting machine equipment technology, and in particular to a paper positioning auxiliary cutter for a paper cutting machine. Background Technology

[0002] In the production of paper and packaging paperboard, the paper needs to be cut to certain specifications. A paper cutter is the equipment used to cut the paper.

[0003] Patent publication number CN213499549U discloses a stable and fixed limiting device for a paper cutter, including a fixed base plate. Two first fixed side plates are symmetrically arranged on the upper end of the fixed base plate. A sliding base plate is fixed to the upper end of the first fixed side plates. A paper pressing platform is provided on the upper end of the sliding base plate. Two first sliding grooves are symmetrically arranged on the upper end of the sliding base plate. Two first sliders are symmetrically arranged on the lower end of the paper pressing platform. The first sliding grooves and the first sliders are slidably connected. A first threaded rod is provided on the inner side of the sliding base plate. This patent, when fixing the paper, directly places the paper on the paper pressing platform and then only uses a pressure plate to press and limit the paper. However, this method of pressing the paper with a pressure plate cannot guarantee that the paper will be completely neat, which can easily affect the quality of the cut paper.

[0004] In conclusion, it is necessary to develop a paper positioning auxiliary cutter for paper cutters that can ensure the neatness of the paper. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies that rely solely on pressing plates to compress paper, which cannot guarantee the neatness of the paper, this invention provides a paper positioning auxiliary cutter for paper cutters that can guarantee the neatness of the paper.

[0006] To achieve the above objectives, the present invention provides the following solution: a paper positioning auxiliary cutter for a paper cutter, comprising:

[0007] The paper cutter body and sliding crossbeams are slidably connected to both the left and right sides of the paper cutter body.

[0008] Multi-stage cylinders are connected to the top of the sliding crossbeam;

[0009] The cutting blade is connected to the bottom of the telescopic rod of the multi-stage cylinder;

[0010] Positioning mechanism: The main body of the paper cutter is equipped with a positioning mechanism for positioning and sorting the paper.

[0011] The paper cutter body is equipped with a flattening mechanism for rolling the paper.

[0012] Furthermore, the positioning mechanisms include:

[0013] Sliding limit block: A sliding limit block for limiting the paper is placed on the top of the paper cutter body. The top of the sliding limit block is evenly spaced with locking holes.

[0014] Limiting slide rails are slidably connected between the upper parts of each adjacent sliding limiting block;

[0015] The limit rail is slidably connected with a locking pin, and the lower part of the locking pin is locked in the locking hole on the sliding limit block.

[0016] The first pressure spring is connected to the upper part of each pin, and the lower end of the first pressure spring is in contact with the limit slide rail.

[0017] Telescopic limit rods are connected to both the front and rear sides of the upper part of the paper cutter body;

[0018] The first linear spring is connected to both the first linear spring and the telescopic limit rod.

[0019] Furthermore, the flattening mechanism includes:

[0020] The motor is connected to the upper front side of the middle part of the paper cutter body;

[0021] The telescopic frame is rotatably connected to the upper middle part of the paper cutter body. The telescopic frame is connected to a spring inside. The upper front side of the telescopic frame is connected to the rear side of the motor's output shaft.

[0022] Rollers: The lower part of the telescopic frame has rollers rotatably connected to both the front and rear sides for rolling the paper.

[0023] The telescopic frame has a locking block connected in the middle of its upper part.

[0024] Furthermore, it also includes a vibration mechanism for striking the main body of the paper cutter, the vibration mechanism comprising:

[0025] A rotating rod is connected to the upper rear side of the telescopic frame;

[0026] A striking bar is slidably connected to the rear of the paper cutter body for striking the paper cutter body;

[0027] Linkages; there are linkages connecting adjacent striking rods.

[0028] The second pressure spring is fitted on the lower part of the striking rod, and the two ends of the second pressure spring are connected to the lower part of the striking rod and the main body of the paper cutter, respectively.

[0029] Furthermore, the bottom of the rotating rod is curved.

[0030] Furthermore, it also includes an actuating mechanism for actuating and supporting the paper, the actuating mechanism comprising:

[0031] Connecting rods are attached to the lower outer side of the sliding crossbeam;

[0032] The top plate and the inner side of the top of the connecting rod are slidably connected to a top plate for supporting the paper.

[0033] The second linear spring is fitted on the lower part of the top plate, and the two ends of the second linear spring are connected to the top plate and the connecting rod, respectively.

[0034] Furthermore, all four sides of the top plate are sloping.

[0035] Furthermore, it also includes a pre-pressing mechanism for pressing and limiting the paper, the pre-pressing mechanism comprising:

[0036] Connecting blocks are attached to both the left and right sides of the upper part of the cutting blade;

[0037] The fourth telescopic rod is connected to each connecting block, and each fourth telescopic rod is connected to a spring.

[0038] The pressure plate and the bottom of the adjacent fourth telescopic rod are both connected to pressure plates used to press and limit the paper.

[0039] This invention has at least one of the following advantages: By placing the paper between the limiting adjustment blocks, the limiting adjustment blocks can maintain the neatness of the paper, thereby improving the cutting effect. Under the pressing action of the rollers, the paper is made denser, preventing the paper from being too fluffy and affecting its neatness, thus affecting the cutting effect. By rotating the rotating rod to squeeze the striking rod, in conjunction with the second pressure spring, the striking rod moves up and down to strike the paper cutter body, causing the paper cutter body to vibrate, thereby making the paper more dense, which facilitates the subsequent cutting of the paper by the cutting blade. Under the reset action of the second linear spring, the top plate moves upward to support the paper, thereby slightly lifting the paper and preventing the last two sheets of paper at the bottom from not being completely cut, thus improving the cutting effect. Under the reset action of the fourth telescopic rod and the spring inside, the pressure plate moves downward to press and limit the paper, thus preventing the paper from moving with the cutting blade when the cutting blade retracts, which would easily damage the paper.

Detailed Implementation

[0052] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0053] Example 1

[0054] A paper positioning auxiliary cutter for a paper cutter, such as Figures 1-6As shown, the paper cutter includes a main body 1, a sliding crossbeam 2, a cutting blade 3, a multi-stage cylinder 4, a positioning mechanism 5, and a flattening mechanism 6. The main body 1 is slidably connected to the sliding crossbeam 2 on both sides. The top of each sliding crossbeam 2 is bolted to a multi-stage cylinder 4. The bottom of the telescopic rods of each multi-stage cylinder 4 is fixed to a cutting blade 3. The main body 1 is equipped with a positioning mechanism 5 for positioning and arranging the paper. The main body 1 is also equipped with a flattening mechanism 6 for rolling the paper. The positioning mechanism 5 includes a sliding limit block 51, a limit rail 52, a locking pin 53, a first pressure spring 54, a telescopic limit rod 55, and a first linear spring 56. Four sliding limit blocks 51 are placed on the top of the main body 1 to limit the paper. Each of the four sliding limit blocks 51 has evenly spaced locking holes on its top. Each pair of adjacent sliding limit blocks 51 is slidably connected to a limiter at the top. The four limit slide rails 52 are each slidably connected to two locking pins 53. The lower part of each locking pin 53 is locked in a locking hole on the sliding limit block 51. Each locking pin 53 is connected to a first pressure spring 54. The lower end of each first pressure spring 54 is in contact with the limit slide rail 52. The upper front and rear sides of the paper cutter body 1 are fixedly connected to two telescopic limit rods 55. Each of the four telescopic limit rods 55 is connected to a first linear spring 56. The flattening mechanism 6 includes a motor 61. The paper cutter body 1 is equipped with a telescopic frame 62, rollers 63, and a locking block 64. A motor 61 is bolted to the upper front side of the middle part of the paper cutter body 1. A telescopic frame 62 is rotatably connected to the upper middle part of the paper cutter body 1. A spring is connected inside the telescopic frame 62. The upper front side of the telescopic frame 62 is connected to the rear side of the output shaft of the motor 61 through a coupling. Rollers 63 are rotatably connected to the front and rear sides of the lower part of the telescopic frame 62. The rollers 63 are used to roll the paper. A locking block 64 is fixed to the middle of the upper part of the telescopic frame 62.

[0055] In use, the operator can adjust the position of the sliding limit block 51 according to the required paper size. The latch 53 is manually pulled upwards, stretching the first pressure spring 54 and releasing the latch 53 from the sliding limit block 51. Then, the operator manually pulls the sliding limit block 51 to adjust the required size. When the sliding limit block 51 moves outwards, it presses the telescopic limit rod 55, compressing the first linear spring 56. After adjustment, the latch 53 is released, the first pressure spring 54 returns to its original position, and the latch 53 moves downwards to reset, engaging the latch 53 into the locking hole on the sliding limit block 51. This limits the sliding limit block 51, centering it for easy cutting of the paper by the cutter 3. The paper is then placed between the sliding limit blocks 51, positioned below the roller 63. Initially, the lower part of the telescopic frame 62 is locked onto the latch block 64, compressing both the telescopic frame 62 and its internal spring. The operator then manually... The telescopic frame 62 is separated from the locking block 64, the spring inside the telescopic frame 62 returns to its original position, causing the telescopic frame 62 to extend, thereby causing the roller 63 to move downwards and contact the paper. Then, the motor 61 is started, and the output shaft of the motor 61 drives the telescopic frame 62 and the roller 63 to rotate, so that the roller 63 can flatten the paper, thereby making the paper more compact. This avoids the paper being too fluffy, which would affect the neatness of the paper and improve the cutting effect. Then, the paper cutter body 1 is started, and the sliding beam 2 is controlled to move the cutting blade 3 and the multi-stage cylinder 4 to adjust the cutting position. After adjustment, the multi-stage cylinder 4 is started, and the telescopic rod of the multi-stage cylinder 4 extends, causing the cutting blade 3 to move downwards, so that the cutting blade 3 cuts the paper. After cutting, the telescopic rod of the multi-stage cylinder 4 is controlled to retract, causing the cutting blade 3 to move upwards and return to its original position. Then, the paper cutter body 1 drives the sliding beam 2 to move outwards and return to its original position. Finally, the cut paper is taken out.

[0056] Example 2

[0057] Based on Example 1, such as Figure 1 and Figure 7As shown, it also includes a shaking mechanism 7, which is used to strike the paper cutter body 1. The shaking mechanism 7 includes a striking rod 71, a connecting rod 72, a second pressure spring 73, and a rotating rod 74. The rotating rod 74 is fixedly connected to the upper rear side of the telescopic frame 62. The bottom of the rotating rod 74 is arc-shaped. Three striking rods 71 ​​are slidably connected to the rear of the paper cutter body 1. The striking rods 71 ​​are used to strike the paper cutter body 1. A connecting rod 72 is fixedly connected between adjacent striking rods 71. The lower part of each of the three striking rods 71 ​​is fitted with a second pressure spring 73. The two ends of the second pressure spring 73 are respectively connected to the lower part of the striking rod 71 and the paper cutter body 1. Initially, the rotating rod 74 presses against the striking rod 71, and the second pressure spring 73 is in a stretched state. When the telescopic frame 62 rotates, it drives the rotating rod 74 to rotate, causing the rotating rod 74 to separate from the striking rod 71. The second pressure spring 73 returns to its original position, causing the striking rod 71 and the connecting rod 72 to move upward. When the rotating rod 74 contacts the striking rod 71, it presses the striking rod 71 to move downward, and the second pressure spring 73 is stretched. This process repeats, allowing the striking rod 71 to strike the paper cutter body 1, causing the paper cutter body 1 to vibrate. This makes the paper more compact and neater, thus facilitating the subsequent cutting of the paper by the cutting blade 3.

[0058] like Figure 1 , Figure 9 and Figure 10 As shown, it also includes a lifting mechanism 8, which is used to lift and support the paper. The lifting mechanism 8 includes a connecting rod 81, a top plate 82, and a second linear spring 83. The lower outer sides of the two sliding crossbeams 2 are each welded with a connecting rod 81. The top inner sides of the two connecting rods 81 are slidably connected to the top plate 82. The top plate 82 is used to lift and support the paper. The front, back, left, and right sides of the two top plates 82 are all inclined surfaces. The lower part of the two top plates 82 is fitted with a second linear spring 83. The two ends of the second linear spring 83 are respectively connected to the top plate 82 and the connecting rod 81. When the sliding beam 2 moves inward, it drives the connecting rod 81 to move inward, causing the connecting rod 81 to drive the top plate 82 to move inward. When the top plate 82 moves inward to contact the sliding limit block 51, since the top plate 82 has inclined surfaces on all four sides, it will be squeezed downward when it contacts the sliding limit block 51, and the second linear spring 83 will be compressed. When the top plate 82 moves inward to contact the bottom of the paper, under the action of the reaction force of the second linear spring 83, the top plate 82 will hold the paper, thus providing support for the paper and preventing the last two sheets of paper from not being completely cut, thereby improving the cutting effect. When the sliding beam 2 moves outward to reset, it drives the connecting rod 81 and the top plate 82 to move outward to reset. When the top plate 82 moves outward to separate from the sliding limit block 51, the second linear spring 83 resets, driving the top plate 82 to move upward to reset.

[0059] like Figure 1 and Figure 11 As shown, it also includes a pre-pressing mechanism 9, which is used to press and limit the paper. The pre-pressing mechanism 9 includes a connecting block 91, a fourth telescopic rod 92 and a pressure plate 93. The two cutting blades 3 are fixedly connected to the left and right sides of the upper part of the connecting block 91. The fourth telescopic rod 92 is fixedly connected to each of the four connecting blocks 91. A spring is connected inside each fourth telescopic rod 92. The pressure plate 93 is fixedly connected to the bottom of two adjacent fourth telescopic rods 92. The pressure plate 93 is used to press and limit the paper. When the cutting blade 3 moves downward, it drives the connecting block 91 downward, which in turn drives the fourth telescopic rod 92 and the pressure plate 93 downward. When the pressure plate 93 moves downward to contact the paper, it stops moving, and the cutting blade 3 continues to move downward. The fourth telescopic rod 92 and its internal spring are compressed, and then the cutting blade 3 passes through the through slot on the pressure plate 93, so that the cutting blade 3 cuts the paper. In this way, the cutting position can be pressed and limited when the cutting blade 3 cuts, preventing the paper from sinking. When the cutting blade 3 moves upward to reset, the fourth telescopic rod 92 and its internal spring reset, so that the pressure plate 93 presses against the paper. In this way, the paper can be prevented from moving with the cutting blade 3 when the cutting blade 3 retracts, which would easily damage the paper. After the fourth telescopic rod 92 and its internal spring have completely reset, the cutting blade 3 continues to move upward, driving the connecting block 91, the fourth telescopic rod 92 and the pressure plate 93 to move upward to reset.

[0060] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
