Description

Technical Field

[0001] This invention relates to the field of conveyor belt splicing, and in particular to a centering structure and a conveyor belt splicing device. Background Technology

[0002] In coal mines and coal conveying systems of thermal power plants, conveyor belt splicing is an important maintenance task. There are two types of conveyor belt splicing: cold splicing and vulcanized splicing. Among them, vulcanized splicing is the most common and frequently used splicing method.

[0003] During the joint bonding process, because the conveyor belts on both sides of the joint are in a free state and far apart, their sag is large under their own weight. Even if the joint is well aligned during the trial closing before applying adhesive, a certain degree of alignment deviation will still occur when it is opened up for adhesive application and then properly closed. Furthermore, personnel need to stand on the conveyor belt to operate during joint adhesive application and closing, and their own weight will also cause uneven stress on the conveyor belt, resulting in alignment deviation. Under these circumstances, the conveyor belt will run off-track during operation and cannot be adjusted. If the deviation is severe, the joint must be cut off and re-bonded, resulting in significant economic losses and affecting the stable operation of the coal conveying system. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to ensure the alignment of the adhesive joint of the conveyor belt and prevent deviation.

[0005] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a centering structure, which includes a first support platform and a second support platform with their tops located on the same horizontal plane; positioning clamps, the two positioning clamps being respectively disposed on the tops of the first support platform and the second support platform, the positioning clamps being used to fix the conveyor belt.

[0006] In a preferred embodiment of the centering structure of the present invention: the first support platform includes two vertically arranged first frames and a first crossbar fixed to the first frames. The two first frames are fixedly connected by a first connecting rod, and a plurality of first connecting rods form an accommodating space with the two first frames. Both first frames are provided with first threaded holes, and a first support plate is installed in the first frame by bolts engaging with the threads of the first threaded holes.

[0007] In a preferred embodiment of the centering structure described in this invention: first connecting blocks are symmetrically fixedly connected to both sides of the first frame located on the upper layer, and the first connecting blocks are detachably connected to the positioning clamps by bolts.

[0008] In a preferred embodiment of the centering structure described in this invention: the first crossbar located in the lower layer has two first long slots symmetrically opened, and the bottom of the first support plate located in the lower layer has a first long groove corresponding to the first long slot, and the size of the first long groove is larger than the size of the first long slot.

[0009] In a preferred embodiment of the centering structure described in this invention: the second support platform includes two vertically arranged second frames and a second crossbar fixed to the second frames. The two second frames are fixedly connected by a second connecting rod. A plurality of second connecting rods and the two second frames form an accommodating space. The top area of ​​the second support platform is larger than the top area of ​​the first support platform. Both of the second frames have second threaded holes, and a second support plate is installed in the second frame by bolts that engage with the threads of the second threaded holes.

[0010] In a preferred embodiment of the centering structure described in this invention: the second frame located on the upper layer has two symmetrically fixed connections to the two sides near the end of the first frame, and the second connecting blocks are detachably connected to the positioning clamps by bolts.

[0011] In a preferred embodiment of the centering structure described in this invention: the second crossbar located on the lower layer has two symmetrically opened second long slots, and the bottom of the second support plate located on the lower layer has a second long groove corresponding to the second long slot, and the size of the second long groove is larger than the size of the second long slot.

[0012] In a preferred embodiment of the centering structure of the present invention: the positioning fixture includes a clamping plate, and a placement groove is provided in the middle of the bottom of the clamping plate, the placement groove allowing the conveyor belt to pass through, and the positioning fixture located on the top of the second support platform is disposed on the side of the second support platform close to the first support platform.

[0013] Another objective of this invention is to provide a conveyor belt bonding device, which includes a bearing unit and a vulcanizing machine. The first support platform and the second support platform are disposed on both sides of the vulcanizing machine, and the top surfaces of the first support platform and the second support platform are at the same level as the top surface of the first part of the vulcanizing machine.

[0014] In a preferred embodiment of the conveyor belt splicing device of the present invention: the bearing unit includes two symmetrically arranged crossbeams, legs fixed to the outside of the crossbeams, connecting holes evenly opened on the crossbeams, and a support member installed on the top of the crossbeams by bolts. The connecting holes are adapted to the first long slot and the second long slot. The vulcanizing machine is installed on the top of the crossbeams. The support includes a base plate, a bracket fixed to the top of the base plate, and an idler roller rotatably mounted on the bracket. The idler roller is used to provide running support for the conveyor belt. The vulcanizing machine also includes a second part, which works in conjunction with the first part to bond the conveyor belt joints.

[0015] The beneficial effects of this invention are as follows: First, the arrangement of the first and second support platforms, and their cooperation with the clamps, provides operators with a stable operating platform, preventing personal safety hazards such as falls from the frame due to unstable footing; Second, it provides planar support for the conveyor belt joint, ensuring that the conveyor belt will not deform due to gravity or when stepped on, thus stabilizing the position of the conveyor belt and ensuring the flatness of the joint; Third, it allows operators to smoothly cut and peel the joint with a cutter, reducing the chance of the cutter accidentally damaging the next layer of canvas, ensuring the quality of joint cutting and peeling, indirectly ensuring the quality of belt bonding, and improving work efficiency.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0019] Reference Figures 1-5 This embodiment provides a centering structure, including a first support platform 1 and a second support platform 2 with their tops on the same horizontal plane; and positioning clamps 3, with the two positioning clamps 3 respectively disposed on the tops of the first support platform 1 and the second support platform 2, and the positioning clamps 3 being used to clamp and fix the conveyor belt S.

[0020] The first support platform 1 and the second support platform 2 are used to support the joint ends of the two conveyor belts respectively. The first support platform 1 supports the upper surface of the S-joint of the conveyor belt. The required length and area of ​​the first support platform 1 can support the joint once, ensuring the stability of the joint bonding in the vulcanizing machine 5. The support of the first support platform 1 also provides space for the workers to stand, ensuring the stability of the workers when standing and cutting, avoiding the centering deviation of the conveyor belt joint caused by standing on an unsupported conveyor belt, and also avoiding the centering deviation problem caused by the weight of the conveyor belt itself.

[0021] The second support platform 2 mainly supports the other joint side of the conveyor belt S. The second support platform 2 clamps and fixes the conveyor belt S on its upper surface through the positioning clamp 3. On the second support platform 2, the lower surface of the joint can be cut and peeled, which provides convenience for the staff.

[0022] The first support platform 1 and the second support platform 2 are at the same height, and the first support platform 1 and the second support platform 2 can be spliced ​​together to form a rectangular working platform. On this working platform, the joint of the conveyor belt S can be directly cold glued. When it is separated, it can be vulcanized and glued together with the vulcanizing machine 5.

[0023] The first support platform 1 and the second support platform 2 cooperate with the positioning clamp 3. The first support platform 1, in cooperation with the positioning clamp 3, controls the spatial state of one joint of the conveyor belt S. The second support platform 2, in cooperation with the positioning clamp 3, controls the spatial state of the other joint. During the stripping process, the joint on the second support platform 2 needs to be bent, which changes its state. The positioning clamp 3 can constrain the translation of the joint during the rotation process, retaining only one rotation process. Thus, after the stripping of the lower surface of the joint is completed after rotation, it can be directly rotated back and can be directly docked with the joint on the first support platform 1, ensuring the alignment effect of the joint. This allows for accurate positioning after gluing without the need for re-docking, improving the gluing efficiency.

[0024] In use, firstly, install the first support platform 1 and the second support platform 2 in their respective positions. Then, place the connectors in appropriate positions for cutting. When cutting the connector placed on the second support platform 2, since the lower surface of the connector is being cut, positioning clamps 3 should be installed on the first and second support platforms 1 and 2 to fix the conveyor belt S. Then, fold the connector on the second support platform 2 in half, ensuring that the folded part is horizontal on the second support platform 2. The positioning clamps 3 also ensure that the connector will not deflect after folding, ensuring the accuracy of subsequent cutting. Then, the operator can perform the cutting operation and connect the two cut connectors. The conveyor belt S is fixed by the positioning clamp 3, and then the cut and stripped parts can be coated with glue. After the glue is applied, there is no need for manual re-alignment of the joints. The two joints can be stacked. With the cooperation of the first support platform 1, the second support platform 2 and the positioning clamp 3, the accuracy of the final alignment is ensured, and the deviation is prevented from causing damage to the operation of the conveyor belt. In order to ensure the stability of the conveyor belt S, the situation where the alignment accuracy of the two joints is not high can be changed to the positioning and gluing method, thereby increasing the alignment accuracy of the cut and stripped parts of the two joints and improving the gluing efficiency. The positioning clamp 3 can also be used with screws to directly nail the conveyor belt S onto the first support plate 17 for further fixing of the conveyor belt S.

[0025] Reference Figures 1-2 In one embodiment provided in this application, the first support platform 1 includes two vertically arranged first frames 11 and a first crossbar 12 fixed to the first frames 11. The two first frames 11 are fixedly connected by a first connecting rod 13, and a receiving space M is formed between the multiple first connecting rods 13 and the two first frames 11. Each of the two first frames 11 is provided with a first threaded hole 14, and a first support plate 17 is installed in the first frame 11 by bolts that are threaded into the first threaded hole 14.

[0026] The first support plate 17 can be placed on the two first frames 11. The first support plate 17 is detachably installed on the first frame 11 by bolts and first threaded holes 14. The first connecting rod 13 provides support for the two first frames 11. The first crossbar 12 strengthens the support for the first support plate 17, ensuring support strength and ensuring the safety of the staff on the wooden board. The space between the two first frames 11 allows the staff to put in or take out the required tools through the storage space M, solving the problem of tools being placed randomly. The hollow design also reduces the weight of this part, making it easier for the staff to carry. The first crossbar 12 and the first connecting rod 13 can be fixed by welding, bolting, etc., to ensure connection strength, allowing the staff to stand stably on the first support platform 1 and the second support platform 2. The wooden board of the lower first frame 11 can also be placed in the storage space M.

[0027] Specifically, the first connecting blocks 16 are symmetrically fixedly connected to both sides of the first frame 11 located on the upper layer. The first connecting blocks 16 are detachably connected to the positioning clamps 3 by bolts.

[0028] The first connecting block 16 is designed to be connected to the positioning clamp 3 by bolts. The two first connecting blocks 16 are set symmetrically so that when the positioning clamp 3 is fixed, the position of the positioning clamp 3 can be quickly positioned and the positioning clamp 3 can be kept vertical.

[0029] Specifically, the first crossbar 12 located on the lower layer has two first long slots 15 symmetrically opened, and the bottom of the first support plate 17 located on the lower layer has a first long groove 18 corresponding to the first long slots 15, and the size of the first long groove 18 is larger than the size of the first long slots 15.

[0030] The first long slot 15 is formed on the lower first crossbar 12, which does not affect the supporting strength of the component. The first long slot 15 allows for detachable installation on the bearing unit 4, ensuring the stability of the device. The first long groove 18 in the lower first support plate 17 corresponds to the first long slot 15, and the size of the first long groove 18 is larger than that of the first long slot 15. The purpose is that after the bolts are fixedly connected to the bearing unit 4 through the first long slot 15, the first support plate 17 can be laid in the lower first frame 11. The bolts at the position of the first long slot 15 will not affect the installation of the lower first support plate 17. Although the lower first support plate 17 has bolt holes for connection with the lower first frame 11, due to the convenience of installation, the lower first support plate 17 does not need to be fixed and can be installed without bolts. It can simply be placed in the first frame 11.

[0031] Reference Figures 3-4In one embodiment provided in this application, the second support platform 2 includes two vertically arranged second frames 21 and a second crossbar 22 fixed to the second frames 21. The two second frames 21 are fixedly connected by a second connecting rod 23. A plurality of second connecting rods 23 and the two second frames 21 form an accommodating space M. The top area of ​​the second support platform 2 is larger than the top area of ​​the first support platform 1. Both second frames 21 are provided with second threaded holes 24. A second support plate 27 is installed in the second frame 21 by bolts that are threaded into the second threaded holes 24.

[0032] The second support plate 27 can be placed and supported by two second frames 21. The second support plate 27 is detachably installed on the second frame 21 by bolts and second threaded holes 24. The second connecting rod 23 creates a certain distance between the two second frames 21 and provides support for the upper second frame 21. The second connecting rod 23 is the same height as the first connecting rod 13, and the second frame 21 and the first frame 11 use the same dimensions of components, all welded from angle steel of the same specification, thus ensuring that the second support platform 2 and the first support platform 1 are at the same height. The second crossbar 22 strengthens the support for the second support plate 27. The support ensures the strength of the support and guarantees the safety of the staff on the wooden board. Since the second frame 21 is relatively long, an appropriate number of second crossbars 22 can be set according to the actual required support strength. The space between the two second frames 21 can also be used for staff to put in or take out the tools they need, solving the problem of tools being placed randomly. The hollow design also reduces the weight of this part, making it easier for staff to carry. The second crossbars 22 and the second connecting rods 23 can be fixed by welding or other methods to ensure the connection strength, so that the staff can stand stably on the first support platform 1 and the second support platform 2. The space M can be used to put the wooden board of the lower second frame 21.

[0033] Furthermore, the first support platform 1 and the second support platform 2 are set at the same angle on the adjacent side. For example, if the side of the first support platform 1 closest to the second support platform 2 is set vertically, then the side of the second support platform 2 closest to the first support platform 1 is also set vertically, so that the two can be spliced ​​together. After splicing, the two form a support platform, which can support the cold bonding of the clamp. When the two are separated and fixed, a vulcanizing machine 5 is set between them, flush with its top surface. Through the cooperation of the first support platform 1, the second support platform 2 and the vulcanizing machine 5, the joint can be vulcanized and bonded, which greatly improves the applicability of the component.

[0034] The area of ​​the second support platform 2 is larger than that of the first support platform 1, mainly in terms of length. It can also be wider, or both the length and width are larger than the first support platform 1. The length of the second support platform 2 is longer, while the width can be set according to the actual use. It can be the same as or different from the width of the first support platform 1, mainly depending on the width of the support under the conveyor belt S.

[0035] If the width of the second support platform 2 is relatively wide, when cutting the joint on the second support platform 2, the positioning clamp 3 can be set in an inclined position, and one side of the positioning clamp 3 is longer and has multiple bolt holes. After the positioning clamp 3 is set in an inclined position, the joint can be folded backward to flip it to one side of the second support platform 2. The width of the second support platform 2 also meets the flipping requirements. After flipping, the lower surface of the joint can also be cut. The angle of the positioning clamp 3 can be set according to the angle of joint cutting, which can make it more convenient for the operator to operate.

[0036] Specifically, the second frame 21 located on the upper layer has two symmetrically fixed connections of second connecting blocks 26 on both sides near the end of the first frame 11. The second connecting blocks 26 are detachably connected to the positioning clamps 3 by bolts.

[0037] Specifically, the second crossbar 22 located on the lower layer has two symmetrically opened second long slots 25, and the bottom of the second support plate 27 located on the lower layer has a second long groove 28 corresponding to the second long slots 25, and the size of the second long groove 28 is larger than the size of the second long slots 25.

[0038] The second connecting block 26 can fix the positioning clamp 3, which is the same as the function of the first connecting block 16. The second long groove 28 is also the same as the function of the first long groove 18, and will not be described in detail here.

[0039] like Figure 5 As an optional embodiment, unlike the above embodiment, the first frame 11 and the second frame 21 in the first support platform 1 and the second support platform 2 can be set to be movable. That is, the two ends of the first frame 11 and the second crossbar 22 that are close to each other are hinged by a rotating shaft 111, and at the hinge position, there is room for rotation for the position supporting the first support plate 17 to prevent motion interference. The reserved space for movement can be set according to the actual application requirements, and no specific angle is limited here.

[0040] One end is hinged, while the other end can have a connecting part. This connecting part includes two angle steels larger than the first frame 11. The inner side of the rotating angle steel slides against the outer side of the angle steel in the first frame 11, and a slide bar 112 is fixedly connected to the inner side of the rotating angle steel. This slide bar 112 slides against a groove 113 on the outer side of the angle steel in the first frame 11. The slide bar 112 and the groove 113 can be inverted trapezoidal in shape, which not only allows for sliding but also provides a limiting function. A first fastening bolt 114 is threaded onto the side wall of the rotating angle steel. The first fastening bolt 114 can be moved so that one end of it abuts against the side wall of the first frame 11. With the arrangement of the slide bar 112 and the slide groove 113, it can achieve the function of limiting the position. The rotating part is set by two angle steels that are hinged to each other and can slide on both sides of the first frame 11 respectively. One side slides with the rotatable angle steel in the first frame 11. When the first fastening bolt 114 is loosened, the side of the first frame 11 near the second frame 21 can be adjusted to change its angle. This setting can adapt to vulcanizing machines 5 with different side angles, thereby increasing the applicable scenarios of the device.

[0041] The same implementation method is applied to the second support platform 2, enabling it to produce the same transformation as the first support platform 1, ensuring that the side of the first support platform 1 and the second support platform 2 that is close to each other can not only be spliced, but also adapt to different vulcanizing machines 5, ensuring that cold bonding or vulcanizing bonding can be achieved for the two joints of the conveyor belt S.

[0042] refer to Figure 6 As an optional embodiment, unlike the previous embodiment, the rotating part consists of only a large-sized angle steel. One end of this angle steel is glued to a rotatable angle steel of the first frame 11 via a rotating shaft 111. The angle steel of the rotating part slides into a fixed angle steel on one side of the first frame 11. Furthermore, the vertical angle steel and the first crossbar 12 in the first frame 11 are both designed to be telescopic, and this telescopic nature allows for fixation using a second fastening bolt 115. The vertical direction mentioned here refers to... Figure 6 The vertical direction is shown in the attached diagram.

[0043] In this embodiment, if it is necessary to adjust the sides of the first support platform 1 and the second support platform 2 according to the shape of the vulcanizing machine 5, the first fastening bolt 114 and the second fastening bolt 115 are loosened, and the angle steel of the rotating part is moved. During the movement, the projected side length of the rotatable angle steel of the first frame 11 in the vertical direction increases, thus widening the width of the first frame 11. After the adjustment is completed, the first fastening bolt 114 and the second fastening bolt 115 are tightened to fix them. After this adjustment, the lateral distance between the first support platform 1 and the second support platform 2 is correspondingly reduced, while their width increases. In some cases, the reduction in length can be compensated by increasing the width to ensure the standing position of the staff. The first support platform 1 and the second support platform 2 can be set up simultaneously, or one of them can be set up in the manner of this embodiment and the other in the manner of the previous optional embodiment. This embodiment can be used when there are requirements for the number of standing staff and the space is small, while the previous optional embodiment can be used if there is no concern about the area limitation. The first support plate 17 and the second support plate 27 can be adjusted and cut according to the adjusted first support platform 1 and the second support platform 2, or the first support plate 17 or the second support plate 27 can be spliced.

[0044] As an optional embodiment, when the positioning clamp 3 is fixed, if the positioning hole on the positioning clamp 3 is located above the first support plate 17 or the second support plate 27, the positioning clamp 3 can be directly fixed to the first support plate 17 or the second support plate 27 by screws, without the participation of the first connecting block 16 or the second connecting block 26. Without affecting the clamping of the conveyor belt S by the positioning clamp 3, that is, the distance between the two screws must be greater than the width of the conveyor belt S, the clamping effect of the conveyor belt S can be ensured. The first support plate 17 and the second support plate 27 are fixed in the first frame 11 and the second frame 21 by bolts. When the first support plate 17 or the second support plate 27 has been used for a long time and cannot bear the weight of a person or the bolts are not firmly fixed, they can be replaced.

[0045] Reference Figure 7 In one embodiment provided in this application, the positioning fixture 3 includes a clamping plate 31, and a placement groove 32 is provided in the middle of the bottom of the clamping plate 31. The placement groove 32 allows the conveyor belt S to pass through. The positioning fixture 3 located on the top of the second support platform 2 is disposed on the side of the second support platform 2 close to the first support platform 1.

[0046] The clamping plate 31 is used to compress the conveyor belt S, and the placement groove 32 is provided to allow the conveyor belt S to pass through. The surface of the placement groove 32 that contacts the conveyor belt S can be fixedly installed with an anti-slip pad. When the conveyor belt S is tightened, it can also provide a certain degree of protection for the conveyor belt S. In addition, the opening at the placement groove 32 can also serve as a reference for both sides of the conveyor belt S, ensuring that it is laid flat in a straight line on the first support platform 1 or the second support platform 2.

[0047] The positioning clamp 3 is positioned near the end of the first support platform 1, that is, near the end of the connector. After the positioning clamp 3 is installed near the first support platform 1, it can leave a lot of space on the rear side of the top of the second support platform 2. Since the lower surface of the conveyor belt S connector on the second support platform 2 needs to be cut off, the connector needs to be folded back along the positioning clamp 3 in order to cut it off. The space left behind the top of the second support platform 2 can accommodate the folded conveyor belt S connector and provide space for workers to operate, ensuring effective support for the personnel.

[0048] The hole for the bolt to pass through can be set as a long slot, which can accommodate different width changes between the two first connecting blocks 16, and can also accommodate the tilt changes of the positioning fixture 3.

[0049] The positioning fixture 3 is not limited to the clamping plate 31, but can also be any other component in the prior art that can cooperate with the first connecting block 16 to fix the conveyor belt S, such as common buckles, etc., without specific limitations here.

[0050] Reference Figures 8-13 This embodiment provides a conveyor belt bonding device, which also includes a bearing unit 4 and a vulcanizing machine 5. The first support platform 1 and the second support platform 2 are disposed on both sides of the vulcanizing machine 5, and the top surfaces of the first support platform 1 and the second support platform 2 are at the same level as the top surface of the first part 51 in the vulcanizing machine 5.

[0051] Specifically, the bearing unit 4 includes two symmetrically arranged crossbeams 41, support legs 42 fixed to the outside of the crossbeams 41, connecting holes 43 evenly opened on the crossbeams 41, and support members 44 installed on the top of the crossbeams 41 by bolts. The connecting holes 43 are adapted to the first long slot 15 and the second long slot 25. The vulcanizing machine 5 is installed on the top of the crossbeams 41. The support member 44 includes a base plate 441, a bracket 442 fixed to the top of the base plate 441, and an idler roller 443 rotatably mounted on the bracket 442. The idler roller 443 is used to provide running support for the conveyor belt S. The vulcanizing machine 5 also includes a second part 52, which works in conjunction with the first part 51 to bond the joint of the conveyor belt S.

[0052] The bearing unit 4 can support the conveyor belt S. It can provide stable support through the crossbeam 41 and the support leg 42. The support member 44 installed on the crossbeam 41 can not only support the conveyor belt S, but also ensure the movement of the conveyor belt S. The connecting holes 43 are evenly opened on the crossbeam 41 for fixing the support member 44. When it is necessary to glue the joint of the conveyor belt S, the support member 44 at the joint needs to be removed. Then, the first support platform 1 and the second support platform 2 are installed on the crossbeam 41 through the first long slot 15 and the second long slot 25, and fixed to the connecting hole 43 with bolts. Then, the joint can be cut and peeled.

[0053] Among them, the base plate 441 and bracket 442 in the support member 44 serve as support, and the base plate 441 can be fixed in the connecting hole 43 by bolts, while the idler roller 443 can rotate to ensure the stable operation of the conveyor belt S. The height of the idler roller 443 is consistent with the height of the top of the first support platform 1 and the second support platform 2, so that the joint of the conveyor belt S can be laid flat and will not tilt during operation.

[0054] The vulcanizing machine 5 can heat and vulcanize the joint to ensure the connection. The conventional vulcanizing machine 5 is rectangular, but it also has a parallelogram shape. The implementation of the first support platform 1 and the second support platform 2 can adapt to the shape changes of the vulcanizing machine 5, ensuring that it can be adapted to vulcanizing machines 5 of various shapes and improving the applicability of the centering structure.

[0055] refer to Figure 12 and Figure 13 The diagram shows the cutting and peeling of the upper and lower surfaces of the two joints of the conveyor belt S. The cutting and peeling angle shown in the diagram is set at an inclination. The upper surface of one joint is in an inclination stepped shape, and the lower surface of the other joint is also in an inclination stepped shape. The two joints can be spliced ​​together. As for the cutting and peeling of the joints, no specific limitation is made here, and reasonable changes can be made according to actual needs.
