Description

Technical Field

[0001] The utility model relates to a disassembly tool, in particular to a disassembly tool used for disassembling a driving roller of a ribbon winding machine. Background Art

[0002] In the tobacco industry, the tobacco lifting belt assembly of the tobacco rolling machine is mainly used to lift the tobacco from the storage area and transport it to the metering trough evenly. The stability of its operation directly affects key physical indicators such as the weight deviation of the cigarette. The tobacco lifting belt assembly of the tobacco rolling machine mainly includes the driving roller, the tobacco lifting belt, the frame, etc. The two ends of the driving roller are connected to the outer ring of the bearing by interference fit, and the inner ring of the bearing is connected to the short shaft by interference fit. The short shaft is fixed to the lifting belt bracket. The driving roller transmits power to the lifting belt, which plays a key role. When working, the motor rotates the driving roller, and the driving roller drives the lifting belt to start moving.

[0003] Since the belt-lifting drive roller is basically in a harsh working environment with high speed, heavy load and dense dust, the belt-lifting drive roller bearing is very easy to be damaged, resulting in the belt-lifting being unable to run stably. The bearing needs to be replaced in time to keep the belt-lifting running normally. Since the drive roller and the bearing, the bearing and the short shaft all adopt interference fit, and the fit clearance is small, after the bearing is damaged, the bearing operating temperature will rise rapidly, and the metal will undergo slight deformation, making the gap between the drive roller, the bearing and the short shaft smaller, resulting in a tighter fit and difficult to separate. In addition, the belt-lifting bracket is very heavy, which makes it difficult to remove the drive roller from the short shaft. The current disassembly method is to use a hydraulic crane to hang the bracket and separate the drive roller from the short shaft by knocking on the edge of the bracket. This disassembly method requires knocking on the bracket, which is easy to cause damage to the bracket on the one hand, and the knocking rate cannot be fast and takes a long time on the other hand. Moreover, the way of hitting the tooling causes the equipment itself to vibrate, and there are also safety hazards. Utility Model Content

[0004] The utility model aims to provide a disassembly tool for disassembling the driving roller of the ribbon lifting machine for solving the problem that the separation and disassembly of the ribbon lifting driving roller and the short shaft in the prior art is laborious or unstable.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a disassembly tool for disassembling the driving roller of the ribbon winding machine, comprising: a support plate, a clamping assembly and a push rod; the clamping assembly is arranged on a side adjacent to the plate surface of the support plate, and can be clamped to the outer wall of the driving roller in a direction parallel to the plate surface of the support plate; one end of the push rod passes through the plate surface of the support plate perpendicularly and is threadedly connected to the support plate, and the other end of the push rod axially passes through the clamping assembly and is used to push on the short shaft; the clamping assembly is detachably and fixedly connected to the support plate through a connecting column.

[0006] The disassembly tool for disassembling the driving roller of the ribbon winding machine described in the utility model is provided with a support plate, a clamping assembly and a pushing rod. The disassembly tool is used in the process of disassembling the driving roller, and the clamping assembly can be clamped tightly to the outer wall of the driving roller along the radial direction of the driving roller. By arranging one end of the pushing rod to pass through the supporting plate perpendicular to the plate surface of the supporting plate, the pushing rod can be screwed in or out along the axial direction of the driving roller; screwing in the pushing rod makes one end of the pushing rod pass axially through the inside of the driving roller and push it to the short shaft, and the other end of the pushing rod is connected to the supporting plate by a thread, so that the supporting plate is subjected to the reverse force transmitted to the pushing rod by the short shaft; the supporting plate then transmits this reaction force to the clamping assembly through the connecting column, and the clamping assembly can be clamped tightly to the outer wall of the driving roller along the radial direction of the driving roller, and combined with the reaction force of the support plate, the driving roller is driven to move axially away from the short shaft, thereby realizing the separation of the driving roller and the short shaft from each other along the axial direction of the driving roller. The utility model twists the push rod, the support plate cooperates with the push rod to provide a push force to the short shaft, the clamping assembly clamps the outer wall of the driving roller, and cooperates with the support plate and the connecting column to interact, so as to generate a reaction force for the driving roller to axially withdraw from the short shaft; there is no need to knock the bracket, nor to push the push rod in diameter, so the driving roller can be separated and disassembled from the short shaft with relatively little effort and easily, shortening the disassembly time of the maintenance personnel to disassemble the ribbon driving roller of the winding machine, improving the convenience of disassembly, so that the damaged bearing in the roller can be replaced in time, so as to quickly complete the maintenance of the winding machine. In addition, the utility model can make the driving roller move and separate relative to the short shaft along the axial direction, and only needs to overcome the friction between the driving roller and the short shaft, so that the disassembly process is smooth and stable, reducing the damage to the bracket and the short shaft, avoiding the risk of personnel injury and the surface of the driving roller being damaged due to disassembly in the traditional disassembly method, largely eliminating the safety hazards in the disassembly process, and improving the safety and stability of disassembly; so that the equipment can be put into production again in a short time, reducing the risk of production task delay caused by equipment damage, and improving production efficiency.

[0007] Preferably, the disassembly tool for disassembling the driving roller of the ribbon winding machine described in the utility model, the clamping assembly includes at least two clamping blocks that can approach and move away from each other, the inner side of the clamping block is provided with a groove matching the outer wall of the driving roller, and the outer side of the clamping block is provided with two first connecting ears for connecting to another adjacent clamping block; the first connecting ears protrude outward, and the corresponding two first connecting ears are telescopically connected by a locking screw.

[0008] As a preferred embodiment of the present invention, the clamping assembly is arranged to have at least two clamping blocks that can be approached or separated from each other. The two clamping blocks can be clamped to the outer wall of the driving roller when they are approached radially along the driving roller. The two matching first connecting ears refer to the two first connecting ears that need to be connected to each other. The first connecting ears protrude outward, which can facilitate the use of a bolt wrench closer to the locking screw, and facilitate the removal or twisting of the locking screw. The first connecting ears are connected by the locking screw, and a driving roller with a smaller diameter can be tightened by tightening the locking screw. By loosening the locking screw, the distance between the two matching first connecting ears is increased, and a driving roller with a smaller diameter can be tightened. The driving roller can be used to disassemble driving rollers with different diameters, thereby increasing the applicability of the disassembly tool.

[0009] Preferably, the disassembly tooling for disassembling the driving roller of the ribbon winding machine described in the utility model is such that the outer wall of the driving roller is provided with a plurality of axially distributed pushing grooves, the width of the pushing grooves matches the thickness of the clamping block, and the clamping block can abut against the side walls of the pushing grooves.

[0010] As a preferred solution of the utility model, a plurality of the pushing grooves are arranged on the driving roller so that the width of the pushing grooves matches the thickness of the clamping block, so that the clamping block can be embedded in the pushing grooves. The pushing rod cooperates with the reaction force of the support plate on the clamping block, so that the clamping block can abut against the side wall of the pushing groove, thereby generating a reverse pushing force on the axial direction of the driving roller, and the action direction is opposite to the action direction of the pushing rod pushing the short shaft. Compared with the clamping block having a greater tightening force on the driving roller, the driving roller can be withdrawn from the short shaft more effortlessly, the effect is more obvious, and the disassembly efficiency is higher without affecting the disassembly stability.

[0011] Preferably, in the disassembly tool for disassembling the ribbon driving roller of the winding and splicing machine described in the utility model, one of the two corresponding first connecting ears is provided with a first threaded through hole for connection of the locking screw, and the other is provided with a first connecting hole for passing the locking screw.

[0012] As a preferred solution of the utility model, one of the two corresponding first connecting ears is provided with a threaded through hole for connection of the locking screw, and the other is provided with a first connecting hole for passing the locking screw. By screwing the locking screw into the threaded through hole, the spacing between the two first connecting ears can be reduced, thereby achieving a stronger effect of tightening the outer wall of the driving roller; relative to screwing in, the spacing between the two first connecting ears is increased by screwing out of the threaded through hole in the opposite direction, thereby achieving loosening from the outer wall of the driving roller, which, on the one hand, facilitates the removal of the clamping assembly, and on the other hand, can be used for disassembling driving rollers of different diameters, and can also temporarily adjust the degree of tightening the driving roller, thereby further enhancing the applicability of the disassembly tool.

[0013] Preferably, the disassembly tool for disassembling the driving roller of the ribbon winding machine described in the utility model is provided with at least two second connecting ears which are outwardly protruding and radially symmetrical on the outer side of the clamping block, one end of the connecting column is axially connected to the second connecting ear, and the other end of the connecting column is axially connected to the support plate.

[0014] As a preferred solution of the utility model, at least two outwardly protruding and symmetrical second connecting ears are provided on the outer side of the clamping block, so that one end of the connecting column is axially connected to the second connecting ear, and the other end of the connecting column is axially connected to the support plate. This allows the second connecting column to be subjected to the force of the support plate and transmitted to the clamping block through the connecting column in a relatively balanced manner. Since the axial reaction force of the support plate is not transmitted symmetrically and distributed on the clamping block, the clamping block may become eccentric and stuck. Through the setting of this preferred solution, the clamping block can be further prevented from getting stuck, thereby reducing the sticking rate of the disassembly tool.

[0015] Preferably, in the disassembly tool for disassembling the driving roller of the ribbon winding machine described in the utility model, the plate surface of the support plate is diamond-shaped, and a second threaded through hole for connecting the push rod is provided in the center of the support plate; the connecting column is axially connected to the corner corresponding to the long diagonal of the support plate.

[0016] As a preferred solution of the utility model, by making the plate surface of the support plate rhombus-shaped and providing a second thread in the center of the support plate, the push rod can be axially connected to the center of the support plate, and the column is axially connected to the angle corresponding to the long diagonal of the rhombus-shaped support plate. Not only can the force of the connecting column be kept symmetrical with the center of the support plate, but also the axial thrust of the push rod and the reaction force of the support plate on the connecting column can be made to act axially and parallel to the thrust, so that the thrust is evenly transmitted to the support plate and radially symmetrically to the connecting column. On the one hand, the loss in the force transmission is reduced, and on the other hand, the force balance of the driving roller can be further maintained during the process of withdrawing the short shaft, further avoiding the occurrence of eccentric jamming of the driving roller, further reducing the failure rate of the disassembly tooling and improving the performance.

[0017] Preferably, the disassembly tooling for disassembling the driving roller of the ribbon winding machine described in the utility model is provided with a connecting groove at the corner corresponding to the long diagonal of the support plate, and the connecting groove is U-shaped with an opening facing outward, and the connecting column can pass through the connecting groove and be clamped to the support plate by a nut.

[0018] As a preferred solution of the utility model, a U-shaped connecting groove opening outward is provided at the corner corresponding to the long diagonal line of the support plate, and the connecting column can be conveniently clamped to the support plate through a locking nut, so that the supporting and force transmission function of the connecting column can be maintained; by loosening the nut and withdrawing one end of the connecting column connected to the clamping block, the support column can be withdrawn from the outer side of the U-shaped connecting groove, thereby disassembling or adjusting the disassembly tool to meet the disassembly use conditions and facilitate the use of the disassembly tool.

[0019] Preferably, in the disassembly tool for disassembling the driving roller of the ribbon winding machine described in the utility model, the middle section of the connecting column is set as a hexagonal column, and both ends of the connecting column are provided with external threads that respectively match and connect the support plate and the clamping assembly.

[0020] As a preferred solution of the utility model, the middle section of the connecting column is set as a hexagonal column, and the two ends of the connecting column are respectively provided with external threads matching the support plate and the clamping assembly. The hexagonal column can be disassembled by screwing the connecting column with a hexagonal wrench, which facilitates the disassembly of the hexagonal column. Moreover, after the connecting column of the hexagonal column is threadedly connected and fastened to the support plate or the clamping block, the cross section of the hexagonal column supports and presses against the plate surface of the support plate or the surface of the clamping block. Compared with columns with other cross sections, the balance of the connecting column in axial force transmission can be further enhanced, the supporting strength of the connecting column can be further enhanced, and the stability of the tooling can be further improved.

[0021] Preferably, in the disassembly tooling for disassembling the driving roller of the ribbon winding machine described in the utility model, the push rod is arranged into at least two sections that can be detachably connected, and the connecting ends of the two sections of the push rod are respectively provided with an internal thread section and a first external thread section that matches the internal thread.

[0022] As a preferred solution of the utility model, by setting the push rod to be detachably connected with at least two sections, on the one hand, it is suitable for disassembly of drive rollers of different lengths, and on the other hand, by disassembling and placing the detachable multi-section push rod, in the working scenario where the drive roller is longer, it is convenient to store the disassembly tool. Then, the connecting ends of the two sections of the push rod are respectively provided with an internal thread section and a first external thread section that cooperates with the internal thread section; the internal thread section and the first external thread section are matched, and the internal thread section can extend into the interior of the first external thread section to form an axial threaded sleeve, so that the push rod can be detachable into multiple sections. Since the push rod needs to transmit the push force axially, this setting can keep the force transmission between the two sections of the push rod along the axial direction, and also enhances the firmness of the multi-section connection to avoid bending or disconnection due to force, and further improves the stability of the tool.

[0023] Preferably, in the disassembly tooling for disassembling the driving roller of the ribbon winding machine described in the utility model, one end of the pushing rod used to push the short shaft is provided with an end cover having a cross-sectional diameter larger than the diameter of the pushing rod, and the surface of the end cover used to push the short shaft is a plane.

[0024] As a preferred solution of the utility model, an end cover with a cross-sectional diameter larger than the diameter of the pushing rod is provided at one end of the pushing rod used for pushing the short shaft, and the surface of the end cover used for pushing the short shaft is a plane, so that after the end of the pushing rod is pushed on the cross section of the short shaft, the pushing rod has a larger contact area than when the pushing rod pushes against the cross section of the short shaft, and the contact with the cross section of the short shaft is more stable, further avoiding slippage or translation of the pushing rod during the pushing process, thereby enhancing the stability of the disassembly device.

[0025] Preferably, in the disassembly tool for disassembling the driving roller of the ribbon winding machine described in the utility model, a hexagonal column section is provided at one end of the push rod passing through the support plate; the hexagonal column section can be rotated in conjunction with a wrench.

[0026] As a preferred solution of the utility model, since the push rod needs to be screwed in or out during use to achieve the purpose of pushing the short shaft, this preferred solution is to set the end of the push rod that passes through the support plate as a hexagonal prism section that can be rotated with a wrench, which is convenient for using a wrench to rotate the push rod. The disassembly device is suitable for disassembling heavier driving rollers such as the driving roller of the winding and splicing machine, and the push rod can be pushed with less effort. Combined with the push rod being provided with a threaded function that cooperates with the support plate, the driving roller can be separated from the short shaft, thereby achieving quick disassembly and facilitating disassembly of the driving roller.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0028] 1. By arranging a support plate, a clamping assembly and a push rod, the disassembly tool is used in the driving roller. By twisting the push rod, the support plate cooperates with the push rod to provide a push force to the short shaft, and the clamping assembly can clamp the outer wall of the driving roller, and cooperate with the support plate to generate a force on the outer wall of the driving roller opposite to the push force of the push rod, so that the driving roller is axially away from the short shaft, and the driving roller can be separated and disassembled from the short shaft more labor-saving and easily, without axially pushing the push rod and knocking the bracket, which shortens the disassembly time of the maintenance personnel for disassembling the ribbon driving roller of the winding and splicing machine, improves the convenience of disassembly, and enables the damaged bearing in the roller to be replaced in time, thereby quickly completing the maintenance of the winding and splicing machine.

[0029] 2. Through the coordinated use of the above-mentioned push rod, support plate and clamping assembly, the driving roller can be axially withdrawn from the short shaft, making the disassembly process smooth and stable, reducing the possibility of damage to the bracket and the short shaft, avoiding possible personal injury in traditional disassembly methods, and avoiding the risk of damage to the driving roller surface due to disassembly. The safety hazards in the disassembly process are eliminated to a large extent, the safety and stability of disassembly are improved, the equipment can be put back into production in a shorter time, reducing the risk of production task delays due to equipment damage, and improving production efficiency.

DETAILED DESCRIPTION

[0039] The utility model is described in detail below in conjunction with the accompanying drawings.

[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0041] Example 1

[0042] refer to Figure 1 As shown, the disassembly tool for disassembling the driving roller of the ribbon winding machine described in this embodiment includes: a support plate 1, a clamping assembly 2 and a pushing rod 3; the clamping assembly 2 is arranged on a side adjacent to the plate surface of the support plate 1, and can be clamped to the outer wall of the driving roller 0 in a direction parallel to the plate surface of the support plate 1; one end of the pushing rod 3 passes through the plate surface of the support plate 1 perpendicularly, and is threadedly connected to the support plate 1, and the other end of the pushing rod 3 axially passes through the clamping assembly 2 and is used to push on the short shaft 00; the clamping assembly 2 is detachably fixedly connected to the support plate 1 through a connecting column 4.

[0043] refer to Figure 2 The use of the utility model is as follows: the clamping assembly 2 is clamped to the outer wall of the driving roller 0 along the radial direction of the driving roller 0, and the push rod 3 is passed through the support plate 1, and then screwed into the driving roller 0 along the axial direction of the driving roller 0 until the push rod 3 can be pushed to the short shaft 00. The push rod 3 is connected to the support plate 1 through a thread, so that the support plate 1 is subjected to the reverse force during the screwing process of the push rod 3. The support plate 1 transmits this reaction force to the clamping assembly 2 through the connecting column 4. The clamping assembly 2 can be clamped to the outer wall of the driving roller 0 along the radial direction of the driving roller 0, driving the driving roller 0 to move axially away from the short shaft 00, thereby separating the driving roller 0 and the short shaft 00 from each other. During the disassembly process, the push rod 3 and the end cover 35 are used to support the end face of the short shaft 00, and the clamping block 21 clamps the outer surface of the driving roller 0. The push rod 3 is rotated clockwise with a wrench, and the driving roller 0 can be separated from the short shaft 00 under the force of the thread, so as to achieve quick disassembly.

[0044] It should be noted that the push rod 3 can be a push screw. The driving roller 0 of the winding machine described in the utility model can be the driving roller 0 of the ZJ17 winding machine VE ribbon, but it is not limited to this type of driving roller 0 disassembly, and can be applied to any scene that can be actually used.

[0045] It should be noted that the “axial direction” and “radial direction” refer to the axial direction and radial direction of the driving roller 0 , the radial direction is parallel to the support plate 1 , and the axial direction is perpendicular to the plane of the support plate 1 .

[0046] like Figure 1 and Figure 3As shown, in this embodiment, the clamping assembly 2 includes at least two clamping blocks 21 that can approach and move away from each other, the inner side of the clamping block 21 is provided with a groove 22 that matches the outer wall of the driving roller 0, and the outer side of the clamping block 21 is provided with two first connecting ears 23 for connecting another adjacent clamping block 21; the first connecting ears 23 protrude outward, and the corresponding two first connecting ears 23 are telescopically connected through a locking screw 24.

[0047] It should be noted that, in this embodiment, Figure 2 As shown, by setting a pushing groove 100 on the outer wall of the driving roller 0, the width of the pushing groove 100 is equivalent to the thickness of the clamping block 21 in the clamping assembly 2, and the clamping block 21 can be embedded in the pushing groove 100. After receiving the reverse pushing force transmitted to the support plate 1 by the pushing rod 3 and then transmitted to the clamping block 21, the side wall of the clamping block 21 pushes the pushing groove 100, thereby driving the driving roller 0 to move axially away from the short shaft 00, so that the force of the clamping assembly 2 is greater, and the driving roller 0 can be withdrawn from the short shaft 00 more quickly and conveniently with less effort.

[0048] It should be noted that if Figure 1 and Figure 3 As shown, the two "corresponding" first connecting ears 23 refer to the two first connecting ears 23 matched and connected by the locking screw 24, such as Figure 3 As shown, a first connecting ear 23 of a left clamping block 21 and a first connecting ear 23 of another right clamping block 21 that need to be connected to each other are corresponding connecting ends.

[0049] In this embodiment, Figure 3 and Figure 4 As shown, one of the two corresponding first connecting ears 23 is provided with a first threaded through hole 231 for connecting the locking screw 24, and the other is provided with a first connecting hole 232 for passing the locking screw 24, and the first connecting hole 232 is a through hole. It should be noted that, Figure 5 The two first connecting ears 23 of a clamping block 21 shown in the figure are respectively provided with a first threaded through hole 231 and a first connecting hole 232. Alternatively, the two first connecting ears 23 of a clamping block 21 may be both provided with the first threaded through hole 231, while the two first connecting ears 23 of another adjacent matching clamping block 21 may be both provided with the first connecting holes 232. There is no limitation here. For example, the left clamping block 21 is an M10 threaded through hole, and the right clamping block 21 is an ordinary through hole of φ10.5. The two are connected and locked by bolts to clamp and fix the driving roller 0.

[0050] It should be noted that the threaded through hole refers to a through hole having an internal thread matching the external thread of the locking screw 24, the first connecting hole 232 refers to a through hole without a thread, and the connection method of the locking screw 24 is that the nut end of the locking screw 24 is connected to the through hole without a thread, and the other end of the locking screw 24 is threadedly connected to the threaded through hole. Figure 1 and Figure 3 By opening an M10 threaded through hole on the two first connecting ears 23 of a clamping block 21 and opening an M10.5 common first connecting hole 232 on the two first connecting ears 23 of another adjacent clamping block 21 that needs to be connected, or by opening an M10 threaded through hole on one of the two first connecting ears 23 of a clamping block 21 and opening an M10.5 common first connecting hole 232 on the other first connecting ear 23 of the same clamping block 21, during the process of connecting the locking screw 24, it is necessary to pay attention to that the nut end of the screw is connected to the side of the first connecting hole 232 without a threaded through hole, so that the locking screw 24 can be screwed into the threaded through hole to reduce the distance between the two first connecting ears 23, and the distance between the two first connecting ears 23 can be increased by screwing out of the threaded through hole in the opposite direction relative to screwing in.

[0051] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, at least two second connecting ears 25 that are outwardly protruding and radially symmetrical are provided on the outer side of the clamping block 21, one end of the connecting column 4 is axially connected to the second connecting ear 25, and the other end of the connecting column 4 is axially connected to the support plate 1.

[0052] In this embodiment, Figure 5-Figure 6 As shown, the surface of the support plate 1 is rhombus-shaped, and a second threaded through hole 11 for connecting the push rod 3 is provided in the center of the support plate 1; the connecting column 4 is axially connected to the corner corresponding to the long diagonal line of the support plate 1.

[0053] In this embodiment, a connecting groove 12 is provided at a corner corresponding to the long diagonal line of the support plate 1. The connecting groove 12 is U-shaped with an opening facing outward. The connecting column 4 can pass through the connecting groove 12 and be clamped to the support plate 1 through a nut. Figure 5-Figure 6 As shown, the support plate 1 is a rhombus, with a U-shaped opening processed symmetrically at its left and right ends along the middle, and an M22 threaded through hole processed in the middle. At the same time, the edges and corners of the upper and lower ends of the workpiece are chamfered.

[0054] like Figure 7As shown, in this embodiment, the middle section of the connecting column 4 is configured as a hexagonal prism, and the two ends of the connecting column 4 are respectively provided with external threads that match the connection support plate 1 and the clamping assembly 2. The hexagonal prism is obtained by processing threads of different sizes at both ends of a regular hexagonal prism. The left side of the workpiece is processed with an M10×30 external thread, and a certain distance is left from the prism body; the right side is processed with an M12×19 external thread. The hexagonal prism is mainly used for connecting the support plate 1 and the clamping block 21. The right side of the hexagonal stud is threadedly connected by a second connecting hole 251 with an M12 internal thread opened on the second connecting ear 25 on the clamping block 21. The second connecting hole 251 can be a threaded through hole or a threaded non-through hole. The other end is fixed to the support plate 1 by a nut. The number of connecting columns 4 matches the number of clamping blocks 21 and the number of second connecting ears 25. Here, it can be as shown Figure 1 As shown, two clamping blocks 21 are provided and each clamping block 21 is provided with a second connecting ear 25 , and two connecting columns 4 equal in number to the clamping blocks 21 are provided.

[0055] In this embodiment, the push rod 3 is provided with at least two sections that can be detachably connected. The connecting ends of the two sections of the push rod 3 are respectively provided with an internal thread section 31 and a first external thread section 32 that cooperates with and connects to the internal thread section 31. Figure 8 As shown, the push rod 3 is divided into an upper section located outside the driving roller 0 and a lower section located inside the driving roller 0. Figure 8 The upper part of the lower screw is as follows Figure 8 As shown in the lower side, the two sections of the push rod 3 are connected with the internal thread section 31 and the first external thread section 32. Figure 8 A second external threaded section 34 with external threads is processed on the upper side of the middle push rod 3, which is mainly used to connect with the threaded hole in the middle of the support plate 1. The top of the push rod 3 is processed into a hexagonal column section 33 so that the push rod 3 can be rotated with a wrench. That is, it can be understood that the end of the push rod 3 passing through the support plate 1 is processed into a hexagonal column section 33; the hexagonal column section 33 can be used to rotate with a wrench, so that the push rod 3 can be twisted conveniently and labor-savingly.

[0056] In this embodiment, Figure 8 As shown, the end of the push rod 3 used to push the short shaft 00 is provided with an end cap 35 whose cross-sectional diameter is larger than that of the push rod 3. The surface of the end cap 35 used to push the short shaft 00 is a plane. The right side of the push rod 3 (the end used to push the short shaft 00, which is also the end extending into the driving roller 0) is also processed with an internal thread, which is used to cooperate with the end cap 35. The end cap 35 is connected to the end of the push rod 3 by bolts, which can increase the force area and avoid damage to the screw. Since the driving roller 0 is relatively long, in order to reduce the processing cost and difficulty and facilitate use and storage, the push rod 3 in the disassembly device is split into two parts, upper and lower, so that it can be changed according to the actual use scenario.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
