Description

Technical Field

[0001] This application relates to the field of paper bowl making technology, specifically to a cutting device and a paper bowl making machine. Background Technology

[0002] Cultivating seedlings using substrate-filled paper pot strips involves directly cutting the strips to create multiple substrate-filled pots. The advantages of paper pots, such as air circulation and ease of transport, reduce seedling damage and improve transplant survival and overall seedling survival rates. Currently, most methods use a drive mechanism to propel the cutting element in a linear motion to cut the paper pot strips into pots. However, existing cutting devices struggle to simultaneously improve cutting efficiency and ensure service life. Summary of the Invention

[0003] In view of the above, it is necessary to provide a cutting device and a paper bowl machine to both improve cutting efficiency and ensure the service life of the cutting device.

[0004] In a first aspect, this application provides a cutting device for cutting paper bowl strips to form paper bowls.

[0005] When the above-mentioned cutting device is working, the transmission component synchronously transmits multiple paper bowl strips, the swing assembly drives the cutting component to swing, approach and extend into the feeding channel, and the cutting component cuts the paper bowl strip in the current feeding channel. The displacement drive component drives the mounting component to move along the first direction, thereby moving the cutting component that has extended into the feeding channel along the first direction, thus cutting all the paper bowl strips in multiple feeding channels in sequence. After all the paper bowl strips have been cut, the swing assembly drives the cutting component to swing again, extending and moving away from the feeding channel, and the displacement drive component drives the mounting component to move back to its original position along the first direction, so as to facilitate the next cutting action.

Detailed Implementation

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two elements or the interaction between two elements. In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0036] See Figure 1 This application provides a cutting device 100 for cutting paper roll strips to form paper rolls. The cutting device 100 includes a transmission member 110, a displacement drive member 120, and a cutting assembly 130. The transmission member 110 has multiple feeding channels Q1 arranged side by side along a first direction X, and the multiple feeding channels Q1 are used to feed paper roll strips through. The displacement drive member 120 is spaced apart from the transmission member 110 along a second direction Y, and the second direction Y intersects the first direction X. The cutting assembly 130 includes a mounting member 131, a swinging assembly 132, and a cutting member 133. The mounting member 131 is convexly connected to the displacement drive member 120 and is configured to move along the first direction X under the drive of the displacement drive member 120. The swinging assembly 132 is disposed on the mounting member 131 and is convexly connected to the cutting member 133. The swinging assembly 132 is used to drive the cutting member 133 to swing, so as to move the cutting member 133 closer to or away from the feeding channels Q1.

[0037] When the cutting device 100 is in operation, the transmission component 110 synchronously transmits multiple paper rolls. The swing component 132 drives the cutting component 133 to swing, approaching and extending into the feeding channel Q1. The cutting component 133 cuts the paper roll in the current feeding channel Q1. The displacement drive component 120 drives the mounting component 131 to move along the first direction X, thereby moving the cutting component 133 extending into the feeding channel Q1 along the first direction X, thus sequentially cutting all the paper rolls in the multiple feeding channels Q1. After all the paper rolls have been cut, the swing component 132 drives the cutting component 133 to swing again, extending and moving away from the feeding channel Q1. The displacement drive component 120 then drives the mounting component 131 to move back to its original position along the first direction X, so as to facilitate the next cutting action. During the cutting process described above, each paper pot strip is cut by the cutting component 133 with a short distance between it and the mounting component 131. This reduces the problems of decreased cutting quality and excessive wear of the cutting component 133 that may be caused by excessive torque. It ensures that each paper pot strip is subjected to a stable and reliable cutting force, thereby improving the cutting quality of the paper pot strip, increasing cutting efficiency, and reducing the damage cycle of the cutting component 133.

[0038] Furthermore, since the displacement drive 120 can drive the cutting element 133 to move along the first direction X, a large number of paper rolls can be cut using a smaller number of cutting elements 133, thereby further reducing the cost of the cutting device 100.

[0039] In some embodiments, see Figure 2 The number of cutting elements 133 is at least two, and the at least two cutting elements 133 are spaced apart along the first direction X. The cutting assembly 130 also includes a connector 135. Two adjacent cutting elements 133 are movably connected through the connector 135. The swing assembly 132 is connected to one of the cutting elements 133 and drives the other cutting elements 133 to swing through the connector 135.

[0040] When the swing assembly 132 drives one of the cutting elements 133 to swing relative to the mounting member 131, the cutting element 133 drives the connecting member 135 to move, and the moving connecting member 135 drives the other cutting element 133 to swing. In this way, multiple cutting elements 133 can be driven to swing simultaneously by one swing assembly 132, reducing the cost of the cutting device 100. At the same time, by setting multiple cutting elements 133, each cutting element 133 can cut only a specified number of paper strips in the feeding channels Q1. When there are many feeding channels Q1, the driving stroke of the displacement drive member 120 can be saved, the cutting efficiency can be improved, and the cutting wear of individual cutting elements 133 can be reduced, extending their service life. Thus, both improving cutting efficiency and extending the service life of the cutting device 100 can be achieved.

[0041] In some embodiments, see Figure 2The connector 135 includes a connecting rod 1351, two connecting bearings 1352, and two rotating rods 1353. The two ends of the connecting rod 1351 are respectively connected to the two connecting bearings 1352. The two rotating rods 1353 are rotatably fitted into the two connecting bearings 1352, and each rotating rod 1353 is connected to a corresponding cutting piece 133. By cooperating with the cutting piece 133 through the connecting bearings 1352, the risk of jamming when the connecting rod 1351 drives the cutting piece 133 to rotate can be reduced.

[0042] In some embodiments, see Figure 2 The cutting component 133 includes a cutting seat 1332, a cutting blade 1331, and a connecting body 1338. The cutting seat 1332 is drive-connected to the swing assembly 132. The cutting blade 1331 is rotatably connected to the cutting seat 1332. The connecting body 1338 is located on the side of the cutting seat 1332. The side of the connecting body 1338 opposite to the cutting seat 1332 has a movable groove C4. A rotating rod 1353 passes through the side wall of the movable groove C4. A portion of the connecting bearing 1352 is rotatably sleeved on the rotating rod 1353 and located within the movable groove C4.

[0043] In some embodiments, see Figure 2 and Figure 3 The swing assembly 132 includes a swing drive 1321 and a linkage 1322. The linkage 1322 is rotatably connected to the cutting seat 1332. The swing drive 1321 is located on the mounting part 131 and connected to the linkage 1322, and is used to drive the linkage 1322 to swing the cutting seat 1332.

[0044] Optionally, see Figure 2 The linkage 1322 extends into the movable groove C4 and is rotatably connected to the side wall of the movable groove C4 via the rotating shaft 1323.

[0045] In some embodiments, the cutting device 100 further includes a frame 143. The mounting bracket 141, the conveyor 110, and the recovery assembly 170 are sequentially spaced along the second direction Y on the frame 143.

[0046] In some embodiments, the cutting blade 1331 is rotatably connected to the swing assembly 132, and the thickness direction of the cutting blade 1331 is parallel to the rotation direction of the cutting blade 1331. The transmission member 110 is provided with a cutting slit Q3 extending along the second direction Y, and the cutting slit Q3 is correspondingly arranged with the cutting blade 1331 along the second direction Y. In this way, the cutting slit Q3 can make way for the cutting blade 1331, so that the cutting blade 1331 swings to the position of passing through the cutting slit Q3 under the drive of the swing assembly 132, which is beneficial for cutting the paper rolls one by one along the first direction X under the drive of the displacement drive member 120. At the same time, the rotatable cutting blade 1331 helps to reduce local wear and extend the service life of the cutting blade 1331.

[0047] Optionally, the outer periphery of the cutting disc 1331 can be set to a circle.

[0048] In some embodiments, see Figure 3 and Figure 4 The transmission component 110 includes a first part 111 and a second part 112. The first part 111 and the second part 112 are spaced apart. The first part 111 has a plurality of discharge sections 113 on its side facing the second part 112. A cutting slit Q3 is defined between the discharge section 113 and the second part 112. The plurality of discharge sections 113 are distributed along a first direction X, and a discharge gap Q2 is defined between the plurality of discharge sections 113. The first part 111 and the plurality of discharge sections 113 define a plurality of first channels Q11, and the second part 112 defines a plurality of second channels Q12. Each first channel Q11 and a second channel Q12 form a feeding channel Q1. Thus, by defining the cutting slit Q3, the discharge gap Q2, and the multiple feeding channels Q1 through the first part 111, the second part 112, and the multiple discharge sections 113, the paper pot strip debris and the matrix inside the paper pot strip generated during the cutting process can be discharged through the discharge gap Q2, reducing the accumulation and blockage of debris in the cutting area, ensuring the reliability of material conveying and the cutting process, and reducing the wear of debris on the cutting disc 1331.

[0049] Optionally, multiple discharge sections 113 can be arranged at intervals or connected to each other.

[0050] In some embodiments, see Figure 4 and Figure 5 The transmission component 110 also includes multiple first guide sections 114 and multiple second guide sections 115. The multiple guide sections 114 are located on the side of the second portion 112 opposite to the first portion 111 along the first direction X. Both the multiple first guide sections 114 and the multiple second guide sections 115 extend along the first direction X. Each feeding channel Q1 has a first guide section 114 on both sides along the first direction X. Multiple feeding channels Q1 have multiple second guide sections 115 on both sides along the first direction X. The multiple second guide sections 115 are higher than the multiple first guide sections 114 along the second direction Y. The first guide sections 114 guide the discharged paper trays to ensure accurate delivery to the next process. The multiple second guide sections 115 provide overall positioning and guidance for the multiple paper trays along the first direction X.

[0051] In some embodiments, see Figure 3 and Figure 5 The cutting device 100 also includes a recycling component 170. The recycling component 170 is located below the cutting slit Q3 along the second direction Y. The recycling component 170 is used to recycle paper roll debris and substrate.

[0052] Optionally, see Figure 3The recycling assembly 170 includes a front plate 171, a rear plate 172, and two guide plates 173. The front plate 171 and rear plate 172 are spaced apart and connected along a third direction Z. The third direction Z, the second direction Y, and the first direction X intersect each other. The third direction Z can be parallel to the transport direction of the paper rolls. The two guide plates 173 are inclinedly positioned between the front plate 171 and the rear plate 172 along the first direction X. The distance between the two guide plates 173 gradually decreases along the second direction Y, away from the cutting seam Q3. Thus, the two guide plates 173 can guide and recycle paper roll debris and substrate.

[0053] In some embodiments, see Figure 3 and Figure 4 The cutting device 100 also includes a clamping assembly 150. The clamping assembly 150 includes a bearing portion 151 and a clamping member 152. The bearing portion 151 is connected to the upstream side of the conveying member 110 along the paper roll conveying direction (e.g., the third direction Z). The bearing portion 151 is provided with a plurality of bearing grooves C1 distributed along the first direction X, and each bearing groove C1 is connected to a corresponding feeding channel Q1. The clamping member 152 is movably disposed relative to the bearing portion 151. The side of the clamping member 152 facing the bearing portion 151 is provided with a plurality of clamping grooves C2 distributed along the first direction X. Each clamping groove C2 is correspondingly disposed to a bearing groove C1, and the clamping groove C2 is used to dock with the bearing groove C1 to position the paper roll.

[0054] When the clamping member 152 approaches the bearing part 151, the clamping groove C2 aligns with the corresponding bearing groove C1 and together defines the clamping cavity to position the paper roll inserted into the clamping cavity; when the clamping member 152 moves away from the bearing part 151, the clamping groove C2 separates from the bearing groove C1 so that the paper roll can be conveyed to the cutting seam Q3. Multiple clamping cavities can position the paper rolls therein, thereby reducing mutual interference between adjacent paper rolls and suppressing the paper rolls from rotating or shifting under the action of the circular cutting blade 1331, which is beneficial to improving the positional accuracy and cut quality of multi-channel cutting.

[0055] In some embodiments, see Figure 3 and Figure 4 The bearing portion 151 is connected to the side of the first portion 111 that is away from the second portion 112 along the third direction Z.

[0056] In some embodiments, see Figure 3 and Figure 6The clamping assembly 150 also includes a support member 153 and a clamping drive member 154. The support member 153 is mounted on the frame 143. The clamping drive member 154 is mounted on the support member 153 and is driveably connected to the clamping member 152 to drive the clamping member 152 to move along the second direction Y. The clamping member 152 is movably fitted to the support member 153 along the second direction Y. Thus, the clamping member 152 can be driven to move closer to or away from the support portion 151 by the clamping drive member 154. The clamping drive member 154 may be a cylinder or a drive motor.

[0057] In some embodiments, see Figure 6 and Figure 7 The clamping component 152 includes a connecting plate 1522 and two clamping plates 1523. The connecting plate 1522 is drively connected to the clamping drive component 154. The two clamping plates 1523 are spaced apart from the connecting plate 1522 along a first direction X. Both clamping plates 1523 are provided with clamping grooves C2.

[0058] Thus, by pressing the paper roll with a thinner clamping plate, damage to the paper roll can be reduced, while ensuring the clamping effect. Optionally, the number of clamping plates 1523 can also be set to multiple.

[0059] In some embodiments, the clamping member 152 includes a clamping body and a plurality of clamping portions distributed along a first direction X. The clamping assembly 150 further includes a plurality of second buffers, and the clamping drive is tractively connected to the clamping body. The plurality of clamping portions are connected to the clamping body one-to-one through the plurality of second buffers, and each clamping portion is provided with a clamping groove C2. When the clamping body approaches the bearing portion 151, each clamping block contacts the corresponding paper roll. For paper rolls with differences in diameter, filling amount, or shape, each clamping block can move independently and cause the corresponding elastic element to undergo different degrees of compression deformation, thereby applying clamping force to each paper roll. This can compensate for the size and shape differences between the multiple paper rolls, reduce the possibility of some paper rolls being under-clamped and rotating, and some paper rolls being over-clamped and crushing, ensuring that each paper roll achieves a relatively stable clamping state.

[0060] Optionally, the second buffer may include a guide portion and an elastic element. The guide portion guides the pressing block to move in a direction closer to or further away from the corresponding bearing groove C1, and the elastic element may be a compression spring sleeved on the guide portion. One end of the elastic element abuts against the pressing body, and the other end abuts against the corresponding pressing block. The second buffer may also be provided with a limiting portion to limit the movement of the pressing block relative to the pressing body and prevent the pressing block from disengaging.

[0061] In some embodiments, see Figure 7The bottom wall of the clamping groove C2 is provided with multiple pressing parts 1521, which are spaced apart circumferentially along the clamping groove C2. When the clamping groove C2 is connected to the bearing groove C1, the multiple pressing parts 1521 press against different areas of the outer circumference of the paper roll strip to increase the friction between the clamping member 152 and the paper roll strip. In this way, the anti-rotation effect on the paper roll strip can be improved without significantly increasing the overall clamping force, reducing the possibility of the circular cutting blade 1331 causing the paper roll strip to rotate, and reducing the concentrated compression and damage to the surface of the paper roll strip by the clamping member 152.

[0062] In some embodiments, see Figure 8 and Figure 9 The cutting device 100 also includes a mounting frame 141 and a first buffer 142. The mounting frame 141 and the transmission member 110 are spaced apart along the second direction Y, and the displacement drive member 120 is disposed on the mounting frame 141. The first buffer 142 is disposed on the mounting frame 141, and the first buffer 142 is located on the side of the mounting member 131 opposite to the displacement drive member 120 along the first direction X.

[0063] When the mounting component 131 is driven to the end of the cutting stroke, the mounting component 131 abuts against the first buffer component 142, and the first buffer component 142 absorbs part of the kinetic energy of the mounting component 131 and the cutting component 133. In this way, the impact and vibration generated when the cutting assembly 130 reaches the end of the lateral stroke can be reduced, the operating noise of the equipment can be reduced, and the service life of the displacement drive component 120, the mounting component 131 and the cutting component 133 can be improved.

[0064] Optionally, in this embodiment, the displacement drive 120 can be a cylinder. The first buffer 142 can be a hydraulic buffer, a spring buffer, or an elastic buffer block.

[0065] In some embodiments, see Figure 9 The mounting component 131 includes a first mounting portion 1311, a second mounting portion 1312, and a connecting portion 1313. The first mounting portion 1311 is slidably fitted to the side of the mounting bracket 141 along a first direction X. The second mounting portion 1312 is slidably fitted to the bottom surface of the mounting bracket 141 along the first direction X. The connecting portion 1313 connects the first mounting portion 1311 and the second mounting portion 1312 along a second direction Y. The swing assembly 132 is connected to one end of the first mounting portion 1311 that is away from the displacement drive member 120 along the first direction X. The displacement drive member 120 is driven by the connecting portion 1313. The cutting assembly 130 is disposed on one side of the second mounting portion 1312 along the second direction Y. In this way, the installation rationality of the swing assembly 132 and the cutting assembly 130 can be improved, ensuring that there is no interference between the swing assembly 132 and the mounting component 131, and ensuring that the swing assembly 132 is driven by the cutting assembly 130 to drive the cutting assembly 130 to swing.

[0066] In some embodiments, see Figure 9 The mounting bracket 141 is provided with a third mounting portion 144, which is correspondingly arranged with the connecting portion 1313 along the first direction X. A first buffer member 142 is provided on the side of the third mounting portion 144 facing the connecting portion 1313 along the first direction X. In this way, the first buffer member 142 achieves a buffering effect by abutting against the connecting portion 1313.

[0067] In some embodiments, see Figure 9 The mounting bracket 141 is provided with two guide rails 145. One guide rail 145 is located on the side of the mounting bracket 141 and extends along the first direction X, while the other guide rail 145 is located on the bottom surface of the mounting bracket 141 and extends along the first direction X. The first mounting part 1311 and the second mounting part 1312 are respectively provided with sliders 146, which slide in cooperation with the corresponding guide rails 145 along the first direction X. In this way, the movement accuracy of the mounting member 131 along the first direction X can be improved. In other embodiments, the mounting member 131 and the mounting bracket 141 can also be guided and cooperated by other guiding structures.

[0068] In some embodiments, the output end of the displacement drive 120 is connected to the connecting portion 1313 via an elastic force transmission assembly. The elastic force transmission assembly includes a force transmission portion and a pre-tightening elastic member. The force transmission portion is connected to the output end of the displacement drive 120 and is slidably disposed relative to the mounting member 131 along a first direction X. The pre-tightening elastic member abuts between the force transmission portion and the mounting member 131, so that the driving force output by the displacement drive 120 is transmitted to the mounting member 131 sequentially through the force transmission portion and the pre-tightening elastic member.

[0069] The pre-tensioning elastic element can be a compression spring, a disc spring, an elastic rubber component, or other structures capable of elastic deformation. The pre-tensioning elastic element has a preset compression amount before the cutting assembly 130 begins to move, thereby avoiding transmission idle stroke between the force transmission part and the mounting part 131.

[0070] When the cutting blade 1331 cuts into the paper roll or moves in the gap between adjacent paper rolls, the cutting resistance changes. The mounting member 131 can generate a small displacement relative to the force transmission part, and absorb part of the load fluctuation through the compression change of the pre-tightened elastic member, so that the driving force applied to the cutting assembly 130 by the displacement drive member 120 gradually changes. In this way, the elastic transmission assembly can mitigate the sudden change in resistance generated when the cutting blade 1331 cuts multiple paper rolls in sequence, reduce the instantaneous acceleration, deceleration and vibration of the cutting assembly 130, and allow the cutting blade 1331 to move laterally in a more stable state, which is beneficial to improving the cutting quality of multiple paper rolls and reducing the impact wear of the cutting blade 1331.

[0071] In some embodiments, the force transmission part is provided with a first rigid abutment surface, and the mounting member 131 is provided with a second rigid abutment surface corresponding to the first rigid abutment surface. When the cutting assembly 130 moves along the cutting direction, a buffer gap is left between the first rigid abutment surface and the second rigid abutment surface, and the displacement drive member 120 transmits driving force to the mounting member 131 through the pre-tightened elastic member; when the cutting assembly 130 moves back along the first direction X, the first rigid abutment surface can abut against the second rigid abutment surface, so that the displacement drive member 120 directly drives the mounting member 131 back to its original position. In this way, the pre-tightened elastic member can be used to buffer load changes during the cutting process, and a rigid transmission can be formed during the return process, reducing the shaking of the mounting member 131 caused by the elastic member's rebound and transmission lag, improving the return accuracy of the cutting assembly 130 and the positional consistency of the next cutting cycle.

[0072] In some embodiments, see Figure 8 The cutting seat 1332 is inclined relative to the first direction X, and the cutting blade 1331 is connected to the end of the cutting seat 1332 away from the mounting member 131. The cutting device 100 also includes a grinding mechanism 160. The grinding mechanism 160 is located on the side of the cutting seat 1332 near the transmission member 110 and away from the mounting member 131. The grinding mechanism 160 is used to grind the cutting blade 1331. The inclined cutting seat 1332 can form an installation space between the mounting member 131 and the cutting blade 1331, allowing the cutting blade 1331 to extend towards the cutting position of the transmission member 110, and reserving space for the grinding mechanism 160. The grinding mechanism 160 is located near the cutting blade 1331, which can shorten the movement stroke required for the grinding wheel 163 to approach the cutting blade 1331; the grinding mechanism 160 is located away from the mounting member 131, which can reduce interference between the grinding mechanism 160 and the swing assembly 132, the displacement drive member 120 and the mounting bracket 141. This helps to improve the structural compactness of the cutting assembly 130, simplify the driving and guiding structure of the grinding mechanism 160, and improve the reliability of the oscillation, lateral movement and automatic grinding process of the cutting assembly 130.

[0073] For example, the grinding mechanism 160 can perform grinding operations on the cutting part 133 when the cutting part 133 is not in operation, thereby improving the sharpness of the cutting part 133. In addition, the grinding mechanism 160 can also perform grinding operations on the cutting part 133 when the cutting part 133 is in operation, without shutting down the cutting assembly 130, thereby improving the cutting efficiency of the cutting part 133.

[0074] The following reference Figure 10 The cutting component 130 of this application is described in an embodiment.

[0075] In some embodiments, see Figure 15The cutting assembly 130 also includes a rotation drive 134. The cutting component 133 further includes a drive wheel 1333, a driven wheel 1334, a guide wheel 1335, a transmission belt 1336, and a connecting shaft 1339. The rotation drive 134 is mounted on the mounting component 131. The rotation drive 134 drives the cutting disc 1331 to rotate via the drive wheel 1333, driven wheel 1334, guide wheel 1335, transmission belt 1336, and connecting shaft 1339. Thus, the cutting component 133 cuts paper rolls in a rotating manner, increasing the number of paper roll positions that the cutting component 133 can cut, extending the wear cycle of the cutting component 133, and thereby improving the replacement cycle of the cutting component 133.

[0076] Please see Figure 15 In some embodiments, the rotation drive 134 includes a rotation drive body 1341 and an output shaft 1342. The cutting assembly 130 also includes a support member. The support member is connected to the mounting member 131. The rotation drive body 1341 is fixedly mounted on the support member, one end of the output shaft 1342 is connected to the rotation drive body 1341, and the other end of the output shaft 1342 passes through the cutting seat 1332 and is connected to the drive wheel 1333.

[0077] The output shaft 1342 passes through the cutting seat 1332, so that the cutting seat 1332 and the output shaft 1342 form a sleeve structure. The output shaft 1342 can guide the cutting seat 1332 to improve the installation efficiency of the cutting seat 1332.

[0078] For example, the rotation drive 1341 is a servo motor.

[0079] Please see Figure 15 The drive wheel 1333 is rotatably connected to the cutting seat 1332, and the drive wheel 1333 is connected to the rotation drive component 134. The driven wheel 1334 is rotatably connected to the cutting seat 1332. The guide wheel 1335 is rotatably connected to the cutting seat 1332 and is located between the drive wheel 1333 and the guide wheel 1335. The transmission belt 1336 is respectively connected to the drive wheel 1333, the guide wheel 1335 and the driven wheel 1334. The two ends of the connecting shaft 1339 are respectively connected to the driven wheel 1334 and the cutting component 133.

[0080] For example, the surfaces of the driving wheel 1333, the driven wheel 1334 and the guide wheel 1335 are each provided with a plurality of toothed grooves, which sequentially engage with the transmission belt 1336.

[0081] For example, the drive pulley 1333, driven pulley 1334 and guide pulley 1335 are located on the same side of the cutting seat 1332, which facilitates the disassembly and assembly of the transmission belt 1336 and improves replacement efficiency.

[0082] In some embodiments, see Figure 15The cutting seat 1332 has a mounting groove C3 on the side opposite to the cutting part 133, and the driving wheel 1333, driven wheel 1334, guide wheel 1335 and transmission belt 1336 are respectively located in the mounting groove C3.

[0083] For example, a portion of the driving pulley 1333, a portion of the driven pulley 1334, a portion of the guide pulley 1335, and a portion of the transmission belt 1336 are accommodated within the mounting groove C3. The mounting groove C3 can limit the movement of the driving pulley 1333, the driven pulley 1334, the guide pulley 1335, and the transmission belt 1336, thereby improving the accuracy of their installation.

[0084] Please see Figure 15 In some embodiments, the cutting device 100 further includes a protective cover 1337. The protective cover 1337 is connected to the cutting seat 1332 and covers the drive wheel 1333, the driven wheel 1334, the guide wheel 1335 and the transmission belt 1336.

[0085] For example, the protective cover 1337 has a groove on the side facing the cutting seat 1332, and part of the driving wheel 1333, part of the driven wheel 1334, part of the guide wheel 1335 and part of the transmission belt 1336 are located in the mounting groove C3, and the remaining part of the driving wheel 1333, the remaining part of the driven wheel 1334, the remaining part of the guide wheel 1335 and the remaining part of the transmission belt 1336 are located in the groove of the protective cover 1337.

[0086] The protective cover 1337 can accommodate part of the driving wheel 1333, part of the driven wheel 1334, part of the guide wheel 1335, and part of the drive belt 1336, and together with the mounting groove C3, it forms a cover for the driving wheel 1333, driven wheel 1334, guide wheel 1335, and drive belt 1336. Therefore, the protective cover 1337 can prevent external dirt from entering the mounting groove C3, thereby reducing the damage caused by external dirt and / or external components to the driving wheel 1333, driven wheel 1334, guide wheel 1335, and drive belt 1336.

[0087] The following reference Figures 11 to 15 The grinding mechanism 160 of this application embodiment is described.

[0088] Please see Figure 11 and Figure 12The grinding mechanism 160 includes a fixing member 161, a drive assembly 162, and two grinding wheels 163. The fixing member 161 is connected to the cutting seat 1332. The drive assembly 162 includes a grinding drive member 1621 and a connecting seat 1622. The grinding drive member 1621 is disposed on the fixing member 161 and connected to the connecting seat 1622, and is used to drive the connecting seat 1622 to move closer to or away from the cutting disc 1331. The two grinding wheels 163 are rotatably connected to the connecting seat 1622 and are spaced apart. Each grinding wheel 163 forms a rotating plane when rotating, and the two rotating planes intersect. Specifically, when the grinding drive unit 1621 drives the connecting seat 1622 to move the two grinding wheels 163 closer to the cutting disc 1331, the cutting disc 1331 extends between the two rotating planes, and the opposite sides of the cutting disc 1331 abut against the two grinding wheels 163 respectively. When the grinding drive unit 1621 drives the connecting seat 1622 to move the two grinding wheels 163 away from the cutting disc 1331, the cutting disc 1331 separates from the two grinding wheels 163.

[0089] For example, the grinding drive 1621 is a telescopic cylinder.

[0090] In the aforementioned grinding mechanism 160, the grinding drive 1621 drives the connecting seat 1622 to move the two grinding wheels 163 closer to or further away from the cutting disc 1331. Each grinding wheel 163 forms a rotating plane when rotating, and the two rotating planes intersect. When it is necessary to grind the cutting disc 1331, the grinding drive 1621 drives the connecting seat 1622 to move the two grinding wheels 163 closer to the cutting disc 1331, so that the cutting disc 1331 extends between the two rotating planes and the opposite sides of the cutting disc 1331 abut against the two grinding wheels 163 respectively. At this time, the cutting disc 1331 is driven to rotate, and the two grinding wheels 163 can grind the opposite sides of the cutting disc 1331 without the need to adjust the angle of the cutting disc 1331 separately, which simplifies the operation process and improves the grinding efficiency.

[0091] The grinding mechanism 160 in the cutting device 100 can shorten the grinding cycle of the cutting disc 1331. Furthermore, the grinding mechanism 160 can grind the cutting disc 1331 simultaneously with the cutting assembly 130's cutting operation, without needing to shut down the cutting device 100, thereby improving the cutting efficiency of the cutting device 100. In addition, the grinding mechanism 160 in the cutting device 100 has a fixed position relative to the cutting assembly 130. Compared to the method where the grinding mechanism 160 and the cutting assembly 130 are separated, requiring the angle of the cutting disc 1331 to be adjusted before grinding, the relative position of the cutting disc 1331 and the grinding mechanism 160 is more stable, which helps improve the uniformity of grinding the cutting disc 1331 by the grinding mechanism 160.

[0092] Please see Figure 12 and Figure 13 In some embodiments, the connecting seat 1622 includes a connecting member 1622a and two guide members 1622b. The connecting member 1622a is connected to the grinding drive member 1621 so as to move closer to or further away from the cutting disc 1331 under the drive of the grinding drive member 1621. The two guide members 1622b are spaced apart and correspond one-to-one with the two grinding wheels 163. One end of each guide member 1622b is connected to the connecting member 1622a. The grinding wheel 163 is rotatably sleeved on the corresponding guide member 1622b. The two guide members 1622b are respectively inclined relative to the connecting member 1622a, and the inclination directions of the two guide members 1622b relative to the connecting member 1622a are opposite.

[0093] The two guide members 1622b extend relative to the connector 1622a, so that the periphery of the guide members 1622b forms the activity space of the grinding wheel 163, thereby reducing the interference of the connector 1622 on the grinding wheel 163.

[0094] Please see Figure 13 In some embodiments, each guide member 1622b includes a guide shaft 1622c, a protrusion 1622d, and a bearing 1622e. One end of the guide shaft 1622c is connected to the connector 1622a. The protrusion 1622d is connected to the end of the guide shaft 1622c away from the connector 1622a and is arranged around the guide shaft 1622c. The bearing 1622e is fixedly sleeved on the guide shaft 1622c and abuts against the side of the protrusion 1622d opposite to the connector 1622a. The grinding wheel 163 is fixedly sleeved on the bearing 1622e.

[0095] The grinding wheel 163 is rotatably connected to the guide shaft 1622c via the bearing 1622e. The bearing 1622e is low in cost and easy to install and remove, thereby improving the installation and removal efficiency and cost of the grinding wheel 163.

[0096] In some embodiments, the connector 1622a has two connecting through holes 1622f, the two connecting through holes 1622f extending in opposite directions, and the two connecting through holes 1622f are correspondingly provided with two guide shafts 1622c. Each guide shaft 1622c includes a main shaft portion 1622g and a locking portion 1622h. One end of the main shaft portion 1622g passes through the corresponding connecting through hole 1622f, a protrusion 1622d is provided at the end of the main shaft portion 1622g away from the connecting through hole 1622f and surrounds the main shaft portion 1622g, a bearing 1622e is fixedly sleeved on the main shaft portion 1622g, and the locking portion 1622h passes through the connector 1622a and the main shaft portion 1622g located in the connecting through hole 1622f to lock the main shaft portion 1622g and the connector 1622a.

[0097] For example, the locking part 1622h is a bolt.

[0098] With the above configuration, the locking part 1622h and the main shaft part 1622g are connected to the connecting part 1622a in a detachable manner, which facilitates the replacement of the grinding wheel 163.

[0099] For example, the protrusion 1622d and the spindle portion 1622g are integrated into one structure to reduce the machining difficulty of the guide 1622b.

[0100] Please see Figure 13 In some embodiments, the guide 1622b further includes a retaining ring 1622k. The retaining ring 1622k is embedded in the grinding wheel 163 and abuts against the bearing 1622e.

[0101] The snap ring 1622k can limit the bearing 1622e in the axial direction, thereby improving the stability of the bearing 1622e when it is fixed.

[0102] Please see Figure 14 In some embodiments, the grinding wheel 163 has a through hole 163a that penetrates both opposite surfaces of the grinding wheel 163. The sidewall of the through hole 163a has a stop body 163b and a limiting groove 163c. The stop body 163b is arranged around the sidewall of the through hole 163a and abuts against the side of the bearing 1622e away from the retaining spring 1622k. The limiting groove 163c is arranged around the sidewall of the through hole 163a to accommodate part of the retaining spring 1622k.

[0103] The limiting groove 163c accommodates the retaining ring 1622k, which can reduce the axial movement of the retaining ring 1622k and improve the stability of the retaining ring 1622k in limiting the position of the bearing 1622e.

[0104] Please see Figure 14 In some embodiments, each grinding wheel 163 includes a body 1631 and a friction element 1632. The body 1631 is rotatably fitted onto a corresponding guide 1622b, and the friction element 1632 is connected to the body 1631 and arranged around the corresponding guide 1622b for rubbing the cutting disc 1331. One friction element 1632 is located on the side of the body 1631 facing away from the connector 1622a, and the other friction element 1632 is located on the side of the body 1631 facing the connector 1622a.

[0105] For example, the friction element 1632 is detachably connected to the main body 1631 to facilitate replacement of the friction element 1632. The friction element 1632 can be a grinding wheel, diamond powder, etc.

[0106] Please see Figure 12 and Figure 15For example, in the two grinding wheels 163, the friction body 1632 of one grinding wheel 163 is connected to the main body 1631 in the direction away from the connecting member 1622a. At this time, the stop body 163b and the protrusion 1622d are arranged opposite to each other in the radial direction of the protrusion 1622d, and the stop body 163b is arranged around the protrusion 1622d. The stop body 163b and the protrusion 1622d respectively abut against the bearing 1622e, and the snap ring 1622k abuts against the side of the bearing 1622e away from the protrusion 1622d.

[0107] Please see Figure 12 and Figure 16 For example, in the two grinding wheels 163, the friction body 1632 of the other grinding wheel 163 is connected to the main body 1631 in the direction toward the connector 1622a. At this time, the stop body 163b and the protrusion 1622d are spaced apart in the axial direction of the protrusion 1622d, and the stop body 163b and the protrusion 1622d respectively abut against the opposite sides of the bearing 1622e. The retaining ring 1622k abuts against the bearing 1622e and is arranged opposite to the protrusion 1622d in the radial direction of the protrusion 1622d. The retaining ring 1622k is arranged around the protrusion 1622d.

[0108] In some embodiments, the grinding drive 1621 is also electrically connected to the control system in the cutting device 100. The control system is used to control the number of cuts of the cutting blade 1331. When the number of cuts reaches the preset requirement, the grinding drive 1621 drives the connecting seat 1622 to drive the two grinding wheels 163 to abut against the opposite sides of the cutting blade 1331.

[0109] For example, the preset number of cuts can be 1000, 2000, 3000, 4000, 5000, etc. For instance, after the cutting blade 1331 cuts the paper roll 5000 times, the two grinding wheels 163 of the grinding mechanism 160 continuously grind the cutting blade 1331 for a predetermined time. The predetermined time can be 3 seconds, 20 seconds, one minute, etc.

[0110] With the above settings, the grinding mechanism 160 intermittently grinds the cutting disc 1331 to improve the cutting effect of the cutting disc 1331 on the paper strip.

[0111] Please see Figure 17 An embodiment of this application also provides a paper roll forming machine 1000, including a machine base 200, a feeding device 300, a loading device 400, and a cutting device 100 of any of the above embodiments. The transmission component 110 of the cutting device 100 is disposed on the machine base 200, the feeding device 300 is disposed on the machine base 200 and used to form paper roll strips, and the loading device 400 is disposed on the machine base 200 and located between the feeding device 300 and the cutting device 100, used to drive the paper roll strips into the feeding channel Q1 of the cutting device 100.

[0112] In the aforementioned paper roll making machine 1000, the feeding device 300 generates paper roll strips, and the loading device 400 drives the paper roll strips generated by the feeding device 300 into the first channel Q11 of the cutting device 100. The loading device 400 and the oscillating drive 1321 work together so that the loading device 400 drives the paper roll strips from the first channel Q11 to the second channel Q12, and under the drive of the displacement drive 120, the cutting device 133 sequentially cuts multiple paper roll strips located in the cutting slit Q3. For example, the loading device 400 and the oscillating drive 1321 adopt intermittent driving methods. When the loading device 400 drives the paper roll strips, the cutting device 133 sequentially cuts multiple paper roll strips located in the cutting slit Q3. When the paper strip moves from the first channel Q11 to the second channel Q12, the swing drive 1321 drives the linkage 1322 to move the cutting assembly 130 away from the transmission assembly 110. When the feeding device 400 is in a stopped state, the swing drive 1321 drives the linkage 1322 to move the cutting assembly 130 closer to the transmission assembly 110 until the cutting assembly 133 cuts the paper strip in the cutting slit Q3, so that a single paper strip enters the second channel Q12. Multiple paper strips in the second channel Q12 are generated in sequence and pushed out of the second channel Q12 in sequence by the paper strip in the first channel Q11.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
