Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of paper cutting machine especially relates to a paper cutting machine. BACKGROUND

[0002] In order to be compatible with the cutting of paper skin of multiple widths, the existing paper cutting machine usually sets a paper library module, and specifically designs the paper library module to include multiple layers of clamping assemblies arranged in the longitudinal direction. The paper skin is clamped by each layer of clamping assemblies before being fed into the paper cutting host. When the paper skin clamped by a specified layer of clamping assemblies needs to be processed, the layer of clamping assemblies will be fed into the paper cutting host. Then the drive shaft in the paper cutting host will drive the paper skin clamped by the corresponding layer of clamping assemblies to continue to be fed into the interior (the clamping assembly will release the paper skin during this process). The paper skin is then cut by the cutter structure inside the paper cutting machine. More specifically, when the other several layers of clamping assemblies are in a standby state that does not need to be fed into the paper cutting host, these several layers of clamping assemblies are currently mostly limited from retracting by the longitudinally extending limit blocks. Since the number of layers of clamping assemblies is large and there is a certain assembly error, there is usually a gap between the clamping assemblies and the limit blocks, which causes the clamping assemblies to shake slightly and collide with the limit blocks when the paper cutting machine is working, resulting in abnormal noise. This seriously reduces the user experience of manufacturers. In addition, the rack used by the current paper cutting host usually includes a cross beam, and the two ends of the drive shaft are connected to the cross beam through bearing seats. Connecting the drive shaft to the cross beam will result in a large structure and volume of the paper cutting machine, which cannot meet the needs of manufacturers who need to use small spaces.

[0043] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and examples.

[0044] Please see Figures 1 to 9 The embodiment provides a paper cutting machine which mainly comprises a paper cutting main machine 10 and a support frame 20, wherein the support frame 20 is arranged at a position adjacent to the paper cutting main machine 10 in the opposite direction of a first direction X, and the support frame 20 is used for supporting a plurality of layers of paper skins arranged in the longitudinal direction, each layer of the paper skins has different width sizes, and the support frame 20 is arranged so that the paper cutting main machine 10 can send the paper skins with appropriate width sizes into the paper cutting main machine 10 and perform cutting work according to actual needs.

[0045] The paper cutting main machine 10 mainly comprises a rack 1, a first driving mechanism 2, a paper warehouse module 3, a second driving mechanism 4, a driving shaft 5, a pressing assembly 6 and a cutter structure 7; the paper warehouse module 3 specifically comprises a lifting seat 31 and a plurality of layers of clamping assemblies 32, wherein the lifting seat 31 is slidably connected with the rack 1 in the longitudinal direction through a connecting guide rail and a sliding block, and the plurality of layers of clamping assemblies 32 are slidably connected with the lifting seat 31 in the first direction X, wherein the clamping assembly 32 has a clamping state for clamping the paper skin and a release state for releasing the paper skin so that the paper skin can move in the first direction X. The first driving mechanism 2 and the second driving mechanism 4 are both connected to the side plates 11 of the rack 1, the first driving mechanism 2 is preferably a combination structure of a motor and a chain, and is used for driving the lifting seat 31 to move in the longitudinal direction, so that each clamping assembly 32 can be moved to a required height, the second driving mechanism 4 is preferably a combination structure of a pneumatic cylinder and a hook, and is used for driving the clamping assembly 32 actually required to move in a straight line in the first direction X, so that the clamping assembly 32 can be sent into the paper cutting machine or withdrawn from the paper cutting machine in the opposite direction of the first direction X. In addition, the bearing seat 12 is fixed on each of the two side plates 11 of the rack 1, the two ends of the driving shaft 5 are connected with the bearing seat 12, the driving shaft 5 is arranged in the first direction X of the clamping assembly 32, the pressing assembly 6 is connected with the rack 1 and arranged in the longitudinal direction of the driving shaft 5 and close to or away from the driving shaft 5 in the longitudinal direction, when the pressing assembly 6 is close to the driving shaft 5, the pressing assembly 6 and the driving shaft 5 are used for jointly clamping the paper skin, the driving shaft 5 rotates to drive the paper skin to move in a straight line in the first direction X, and the cutter structure 7 is connected with the rack 1 and arranged in the first direction X of the driving shaft 5; when the pressing assembly 6 is away from the driving shaft 5, the paper skin can be reset in the opposite direction of the first direction X under the clamping of the clamping assembly 32.

[0046] Specifically, when the paper cutter of this solution is working, the first drive mechanism 2 drives the lifting seat 31 of the paper storage module 3 to move, causing a designated layer of clamping components 32 on the paper storage module 3 to move to a designated height. Then, the second drive mechanism 4 drives this layer of clamping components 32 to move along the positive direction of the first direction X to a preset position. During this process, the clamping components 32 always clamp the corresponding paper. At this time, the incoming paper will be located between the drive shaft 5 and the pressing component 6. Then, the pressing component 6 moves closer to the drive shaft 5 and clamps the paper together with the drive shaft 5. At this time, the incoming clamping component 32 can be switched to the state of releasing the paper. The number of rotations of the drive shaft 5 can drive the paper to be processed to move a designated distance along the first direction X. The cutting tool structure 7 performs the paper cutting operation. When it is necessary to cut a different width of paper, the clamping component 6 moves away from the drive shaft 5, so that the paper is not subject to the clamping force of the drive shaft 5 and the clamping component 6. The clamping component 32 that has entered the paper cutter will switch from the paper feeding state to the paper clamping state. Then, under the drive of the second drive mechanism 4, the clamping component 32 moves backward in the opposite direction of the first direction X and resets to the initial position. Then, the first drive mechanism 2 drives the corresponding layer of clamping component 32 to move to a suitable height, and then the second drive mechanism 4 drives the corresponding layer of clamping component 32 to enter the preset position along the first direction X to change to another width of paper for cutting.

[0047] In addition, such as Figure 4 As shown, the lifting seat 31 has a blocking block 33 fixed at the position of each layer of clamping assembly 32. The blocking block 33 is set on the path of the clamping assembly 32 moving in the opposite direction of the first direction X. When the clamping assembly 32 and the corresponding blocking block 33 abut against each other, the blocking block 33 will restrict the clamping assembly 32 from moving in the opposite direction of the first direction X. Preferably, the blocking block 33 and the clamping assembly 32 are magnetically attracted to each other when they abut against each other. That is, when the multi-layer clamping assembly 32 is in a standby state and does not need to enter the paper cutter, this solution uses magnetic attraction to restrict multiple clamping assemblies 32 to a corresponding blocking block 33, thereby solving the problem of the multi-layer clamping assembly 32 shaking and producing abnormal noise due to processing errors or assembly errors. Preferably, a magnet is fixed on the side of the blocking block 33 facing the clamping assembly 32. In addition, this solution also provides bearing seats 12 on the two side plates 11 of the frame 1, so that the two ends of the drive shaft 5 can be connected to the side plates 11 through the bearing seats 12. The drive shaft 5 is not connected to the crossbeam, which helps to reduce the structural volume of the paper cutter to meet the needs of manufacturers who need to use it in a small space.

[0048] Please refer to the following: Figures 3 to 7The clamping assembly 32 specifically comprises a support plate 321, a mounting plate 322, a driving cylinder 323 and a clamping plate 324; the support plate 321 and the mounting plate 322 are spaced apart and fixedly connected with each other, and both the support plate 321 and the mounting plate 322 are slidably connected with the lifting seat 31 in the first direction X by means of connecting the two ends of the support plate 321 and the mounting plate 322 with the rollers 325; at least one driving cylinder 323 is fixed on the mounting plate 322, and the clamping plate 324 is connected with the driving cylinder 323; the driving cylinder 323 is used to drive the clamping plate 324 to move close to or away from the support plate 321. When the clamping plate 324 moves close to the support plate 321, the clamping plate 324 and the support plate 321 jointly clamp the paper cover; at this time, the clamping assembly 32 is in the clamping state of clamping the paper cover; when the clamping plate 324 moves away from the support plate 321, the support plate 321 supports the paper cover at this time, but the paper cover can move along the first direction X under the driving of the driving shaft 5; at this time, the clamping assembly 32 is in the release state of releasing the paper cover.

[0049] Please refer to Figure 2 In fact, the pressing assembly 6 comprises an actuator 61 and a pressing wheel 62; the actuator 61 is fixed on the rack 1 and connected with the pressing wheel 62; the actuator 61 is used to drive the pressing wheel 62 to move close to or away from the driving shaft 5 in the longitudinal direction; the pressing wheel 62 can rotate relative to the actuator 61; the central axis of the rotation of the pressing wheel 62 and the central axis of the rotation of the driving shaft 5 are both parallel to the second direction Y. In operation, the paper cover and the driving shaft 5 maintain a large force under the pressure of the pressing wheel 62, so that when the driving shaft 5 rotates, the driving shaft 5 can drive the paper cover to move along the first direction X to a position that can be cut by the cutter structure 7 through frictional contact. By arranging the rotatable pressing wheel 62, the friction between the paper cover and the pressing assembly 6 when the paper cover moves along the first direction X can be reduced, and the risk of paper cover wear can be reduced.

[0050] The existing cutter structure usually has a pressing ring and a cutter at the same time; the pressing ring is used to press the paper cover to form a crease, so that the paper cover can be folded according to the preset shape in the subsequent process; the cutter is used to cut the paper cover, so that the paper cover is cut into the required shape. At present, the pressing ring and the cutter are usually arranged in the transverse direction and controlled by independent drivers to move up and down; this kind of cutter structure has the disadvantage of large size, so that the size of the paper cutter is also large; in addition, in order to improve the cutting efficiency, a driving module is usually connected to each cutter structure to move each cutter structure to the required position and press the paper cover or cut the paper cover at the same time; the multiple driving modules also occupy a lot of space, which also makes the size of the paper cutter large. In order to solve the problem that the existing cutter structure has a large size and the paper cutter has a large structure size, the following structural improvements are made in the present scheme:

[0051] Please refer toFigure 8 And Figure 9 The paper cutting machine of the embodiment specifically comprises at least one cutter structure 7 as a horizontal cutter and at least one cutter structure 7 as a vertical cutter, the horizontal cutter and the vertical cutter are arranged at an angle of 90° with each other, and through the combination of the horizontal cutter and the multiple sets of vertical cutters, the paper skin can be cut according to the preset shape and at the same time the creases can be pressed at the preset positions of the paper skin. The embodiment adopts at least two sets of cutter structures 7, and specifically preferably adopts multiple sets of cutter structures 7 as vertical cutters, and the multiple sets of cutter structures 7 are all slidingly connected with the rack 1 in the second direction Y. In addition, the paper cutting machine of the embodiment further comprises a belt driving module 9 connected to the rack 1, the driving direction of the belt driving module 9 is parallel to the second direction, and the multiple sets of cutter structures 7 all have a state of clamping or releasing the belt. Through the design of the cutter structure 7 having the state of clamping or releasing the belt, the horizontal cutter and the multiple sets of vertical cutters can be controlled to move to the specified positions through one belt driving module 9. Through the adoption of the above-mentioned multiple sets of cutter structures 7, it is beneficial to make the paper cutting machine have a smaller structural volume under the condition of higher paper cutting efficiency, so as to meet the purchasing demand of the paper cutting manufacturer who has higher paper cutting efficiency but limited indoor space.

[0052] Please refer to Figure 10 And Figure 11 The cutter structure 7 is specifically designed to comprise a fixed seat 71, a first driver 72, a swing seat 73, a second driver 74, a cutting knife 75, a pressing ring 76, a belt clamping mechanism 78 and three guide wheels 77. One end of the first driver 72 is rotatably connected to the fixed seat 71 at P, the end of the first driver 72 away from the fixed seat 71 is rotatably connected to the swing seat 73 at Q, and the end of the swing seat 73 away from the first driver 72 is rotatably connected to the fixed seat 71 at M. The three guide wheels 77 are all located inside the pressing ring 76 and are all connected to the swing seat 73. The outer wall of one of the guide wheels 77 elastically abuts against the inner ring of the pressing ring 76, and the inner ring of the pressing ring 76 abuts against the outer walls of the other two guide wheels 77 under the elastic force of the one guide wheel 77. The inner ring of the pressing ring 76 abuts against the outer walls of the three guide wheels 77 at the same time to achieve the purpose of swinging together with the swing seat 73. The cutting knife 75 is also arranged in the inner ring of the pressing ring 76, so that the cutting knife 75 occupies the internal space of the pressing ring 76, thereby saving the volume of the whole cutter structure. The second driver 74 is connected to the swing seat 73 and the cutting knife 75 respectively, and is used to drive the cutting knife 75 to extend outward relative to the outer ring of the pressing ring 76 or to retract inward into the pressing ring 76. The belt clamping mechanism 78 has a clamping state of clamping the belt and a releasing state of releasing the belt.

[0053] Specifically, when the paper skin needs to be creased, the cutter 75 needs to be retracted into the pressing ring 76 under the drive of the second driver 74, and the swing seat 73 is swung downward relative to the fixed seat 71 under the drive of the first driver 72, and the three guide wheels 77 will also swing downward when the swing seat 73 swings, and the three downward swinging guide wheels 77 will drive the pressing ring 76 to move downward because the inner ring of the pressing ring 76 is in contact with the outer wall of the three guide wheels 77, and the downward moving pressing ring 76 will crease the paper skin; when the paper skin needs to be cut, the cutter 75 needs to be extended outward relative to the outer ring of the pressing ring 76 under the drive of the second driver 74, and then the swing seat 73 is swung downward relative to the fixed seat 71 under the drive of the first driver 72, and the second driver 74 and the cutter 75 will move downward together under the swing of the downward swinging swing seat 73, and the downward moving cutter 75 will cut the paper skin. Compared with the existing solution of arranging the cutter 75 and the pressing ring 76 transversely, the cutter structure of the present solution is more compact, which is conducive to reducing the size of the paper cutter. In addition, by loosening or clamping the belt through the belt clamping mechanism 78, the distance between the multiple cutter structures 7 can be adjusted under the drive of the belt, so that the multiple cutter structures 7 can be moved to the preset position and work at the same time, so as to improve the cutting efficiency of the paper cutter. By arranging the belt clamping mechanism 78 on the cutter structure 7, it is not necessary to connect a set of driving module to each cutter structure 7, and the distance between multiple cutter structures can be adjusted by only one belt, which is not only conducive to further greatly reducing the structure size of the paper cutter, but also can reduce the production cost of the paper cutter.

[0054] Please refer to Figure 10 and Figure 11 again, the fixed seat 71 specifically includes a first seat body 711 and a second seat body 712 fixedly connected, the first seat body 711 extends transversely, and the second seat body 712 extends longitudinally, one end of the first driver 72 is rotatably connected to the first seat body 711 at P, and the end of the swing seat 73 away from the first driver 72 is rotatably connected to the second seat body 712, and the first seat body 711, the second seat body 712, the swing seat 73 and the first driver 72 together form a quadrilateral structure, a part of the pressing ring 76 and the second driver 74 are accommodated in the quadrilateral structure, and the belt clamping mechanism 78 is connected between the first seat body 711 and the pressing ring 76. By designing the fixed seat 71 and arranging other parts as described above, the cutter structure as a whole can be further compact, thereby being conducive to further reducing the structure size of the paper cutter.

[0055] Please refer to Figure 10 and Figure 11The first seat body 711 is provided with a clamping portion 7111, and the belt clamping mechanism 78 comprises a third driver 781 and a clamping block 782 connected with each other. The third driver 781 is preferably fixed on the first seat body 711. The third driver 781 is connected with the clamping block 782. The third driver 781 is used to drive the clamping block 782 to approach or move away from the clamping portion 7111. When the clamping block 782 approaches the clamping portion 7111, the clamping block 782 is used to clamp the belt together with the clamping portion 7111, so that the cutter structure can be driven to the required position under the drive of the belt. When the clamping block 782 moves away from the clamping portion 7111, the cutter structure will loosen the belt. The cutter structure 7 in the loosened state cannot follow the movement of the belt. At this time, the belt can drive another cutter structure 7 to move. That is, only one belt is needed to adjust the distance between multiple cutter structures 7, so as to realize efficient cutting of the paper skin and greatly reduce the structural volume of the paper cutter. Preferably, the clamping block 782 approaches or moves away from the clamping portion 7111 along the horizontal direction, so that the clamping block 782 and the clamping portion 7111 clamp the belt along the horizontal direction.
