Abstract
Description
Technical Field
[0001] This invention relates to the field of extruder screw disassembly technology, and more specifically, to an extruder screw disassembly device. Background Technology
[0002] In the processing of polymer materials such as plastics and rubber, extruders are the core equipment for melting, mixing, and molding materials. The screw inside, as a key transmission and conveying component, needs to be disassembled regularly for cleaning, maintenance, or replacement to ensure stable operation of the extruder and product quality. Currently, extruder screws are mainly disassembled using a lifting method, which involves using lifting equipment in conjunction with manual operation to remove the screw. During the screw disassembly process, operators need to repeatedly adjust the lifting point position, pull the screw in sections, and manually support it to prevent it from colliding with the inner wall of the barrel. This process not only consumes a lot of manpower but also results in low disassembly efficiency due to frequent starts, stops, and posture adjustments. Summary of the Invention
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an extruder screw disassembly device that can improve the disassembly efficiency of the extruder screw.
[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, this application provides an extruder screw disassembly device, comprising: a clamping device including a base and a clamping assembly, the clamping assembly being disposed on the base, the clamping assembly including at least two clamping members, the two clamping members being symmetrically arranged and capable of approaching or moving away from each other; a disassembly device including a first driving member and a first transmission member, the first transmission member extending along a first direction, the base being connected to the first transmission member, the first driving member being connected to the first transmission member and used to drive the first transmission member to rotate around the first direction, so that the base moves along the first direction; and a fixing device disposed at one end of the first transmission member along the first direction.
[0005] In an optional embodiment, the disassembly device further includes a guide member with a guide groove extending along the first direction. The first transmission member and the base are both disposed within the guide groove, and the base is in contact with the groove wall of the guide groove.
[0006] In an optional embodiment, the clamping assembly further includes at least two second driving members, each of which is connected to one of the clamping members and is used to drive the clamping members so that the symmetrically arranged clamping members clamp the screw.
[0007] In an optional embodiment, the guide member is further provided with a first clearance hole, which extends along the first direction and communicates with the guide groove. The driving end of the second driving member passes through the first clearance hole and is connected to the clamping member.
[0008] In an optional embodiment, the disassembly device further includes a connecting plate disposed at the edge of one end of the guide groove along the first direction, and the first driving member is connected to the connecting plate.
[0009] In an optional embodiment, the disassembly device further includes a second transmission component, which is connected to the first transmission component and the first drive component.
[0010] In an optional embodiment, the clamping device further includes a disassembly aid for connecting to the end of the screw and clamping between the clamping members of any pair of clamping assemblies.
[0011] In an optional embodiment, the fixing device includes a first fixing component, the first fixing component including a support member and a first fixing member, the support member having at least one limiting groove for bearing at least a portion of the screw, and the first fixing member being connected to the end of the support member away from the clamping component along a first direction.
[0012] In an optional embodiment, the first fixing component further includes a third driving member, which is connected to the support member and is used to drive the support member to move along a second direction; wherein the second direction is perpendicular to the first direction.
[0013] In an optional embodiment, the fixing device further includes a second fixing component, the second fixing component including a second fixing member disposed at one end of the support member near the clamping component along a first direction.
[0014] The extruder screw disassembly device of this application has the following advantages: In the extruder screw disassembly device of this application, since the clamping assembly includes at least two clamping members, and the two clamping members are symmetrically arranged and can move closer or further apart from each other, the screw can be clamped between the two clamping members during the disassembly of the extruder screw. This eliminates the need for manual support of the screw during disassembly and achieves a fixed connection between the screw and the clamping device. During the disassembly of the extruder screw, the extruder body is located at one end of the first transmission member along the first direction. The first driving member can drive the first transmission member to rotate around the first direction, causing the base to move along the first direction away from the extruder body. This, in turn, causes the base to drive the screw to move along the first direction away from the extruder body. Since the screw extends along the first direction in the extruder, as the screw moves along the first direction, it gradually disengages from the extruder, thus achieving the disassembly of the extruder screw. Furthermore, the fixing device can be positioned at the end of the first transmission member away from the extruder body along the first direction. Thus, when the screw detaches from the extruder, the fixing device can support part of the screw. In summary, when disassembling the screw, there is no need for extensive manual adjustments, and the screw can be prevented from bending and deforming due to suspension, thereby improving the disassembly efficiency of the extruder screw.

[0023] Reference Figure 1 as well as Figure 2 As shown, the extruder screw disassembly device involved in the embodiments of this application includes: a clamping device 100, a disassembly device 200, and a fixing device 300.
[0024] Specifically, the clamping device 100 includes a base 110 and a clamping assembly 120. The clamping assembly 120 is disposed on the base 110 and includes at least two clamping members 121. The two clamping members 121 are symmetrically arranged and can move closer to or further away from each other. The disassembly device 200 includes a first driving member 210 and a first transmission member 220. The first transmission member 220 extends along a first direction x. The base 110 is connected to the first transmission member 220. The first driving member 210 is connected to the first transmission member 220 and is used to drive the first transmission member 220 to rotate around the first direction x, so that the base 110 moves along the first direction x.
[0025] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle.
[0026] In the extruder screw disassembly device of this application, since the clamping assembly 120 includes at least two clamping members 121, and the two clamping members 121 are symmetrically arranged and can move closer or further away from each other, when disassembling the extruder screw 21, the screw 21 can be clamped between the two clamping members 121, thus eliminating the need for manual support of the screw 21 during disassembly, and simultaneously achieving a fixed connection between the screw 21 and the clamping device 100. During the disassembly of the extruder screw 21, the extruder body 22 is located at one end of the first transmission member 220 along the first direction x, and can be driven by the first driving member 210 to rotate around the first direction x, so that the base 110 moves along the first direction x in a direction away from the extruder body 22, thereby causing the base 110 to drive the screw 21 to move along the first direction x in a direction away from the extruder body 22. In the extruder, the screw 21 extends along the first direction x. Therefore, when the screw 21 moves along the first direction x, it can gradually disengage from the extruder, thereby achieving the disassembly of the extruder screw 21. Furthermore, a fixing device 300 can be positioned at the end of the first transmission member 220 away from the extruder body 22 along the first direction x. Thus, after the screw 21 disengages from the extruder body 22, the fixing device 300 can support a portion of the screw 21. In summary, when disassembling the screw 21, there is no need for extensive manual adjustments, and the screw 21 can be prevented from bending and deforming due to suspension, thereby improving the disassembly efficiency of the extruder screw 21.
[0027] Specifically, in this embodiment, the extruder includes a plurality of screws 21 arranged in a manner such that any two adjacent screws 21 are engaged and connected. In the clamping assembly 120, two clamping members 121 are symmetrically arranged, one clamping member 121 clamps one of the outermost screws 21, and the other clamping member 121 clamps the other outermost screw 21, so as to achieve simultaneous clamping of the plurality of screws 21 of the extruder.
[0028] Reference Figure 2 As shown, the disassembly device 200 also includes a guide member 230, which is provided with a guide groove 231. The guide groove 231 extends along the first direction x. The first transmission member 220 and the base 110 are both disposed in the guide groove 231, and the base 110 is in contact with the groove wall of the guide groove 231.
[0029] In this embodiment, since the guide groove 231 extends along the first direction x and the base 110 is in contact with the groove wall of the guide groove 231, when the base 110 moves along the first direction x, the guide groove 231 can guide the movement of the base 110 to ensure the accuracy of the direction of the base 110's movement along the first direction x, avoid the base 110 from deviating during the movement, and reduce the possibility of the screw 21 colliding with the extruder body 22 during the disassembly process.
[0030] Reference Figure 3 as well as Figure 4 As shown, the clamping assembly 120 also includes at least two second driving members 122, each second driving member 122 being connected to a clamping member 121 and used to drive the clamping member 121 to move so that the symmetrically arranged clamping members 121 clamp the screw.
[0031] In this embodiment, the second driving member 122 can drive the corresponding clamping member 121 to move, thereby clamping the screw 21 between the two symmetrically arranged clamping members 121 to achieve the clamping of the screw 21.
[0032] Reference Figure 2 As shown, the base 110 has a mounting groove 111 and a second clearance hole 112. The second clearance hole 112 penetrates the groove wall of the mounting groove 111. The clamping assembly 120 is disposed in the mounting groove 111. The driving end of the second driving member 122 passes through the second clearance hole 112 and is connected to the clamping member 121. In this way, the clamping member 121 can be driven to move within the mounting groove 111 by the second driving member 122, thereby realizing the movement of the clamping member 121 relative to the base 110.
[0033] Continue to refer to Figure 2 As shown, the guide member 230 is also provided with a first clearance hole 232. The first clearance hole 232 extends along the first direction x and communicates with the guide groove 231. The driving end of the second driving member 122 passes through the first clearance hole 232 and is connected to the clamping member 121.
[0034] In this embodiment, since the driving end of the second driving member 122 passes through the first clearance hole 232, the driving end of the second driving member 122 can simultaneously pass through both the first clearance hole 232 and the second clearance hole 112, allowing the driving end of the second driving member 122 to enter the guide groove 231, thereby achieving the connection between the second driving member 122 and the clamping member 121. When the base 110 moves along the first direction x, the base 110 will drive the second driving member 122 to move along the first direction x. Since the first clearance hole 232 extends along the first direction x, when the base 110 drives the second driving member 122 to move along the first direction x, the groove wall of the guide groove 231 can be prevented from interfering with the movement of the second driving member 122.
[0035] Reference Figure 3 As shown, the clamping device 100 also includes a connector 140, one end of which is connected to the second drive member 122, and the other end of which is connected to the base 110. In this way, the other end of the second drive member 122 can also be connected to the base 110 through the connector 140 to further fix the second drive member 122.
[0036] Reference Figure 2 As shown, the disassembly device 200 also includes a connecting plate 240, which is disposed at the edge of one end of the guide groove 231 along the first direction x, and the first driving member 210 is connected to the connecting plate 240.
[0037] In this embodiment, the first driving member 210 can be fixed by the connecting plate 240 to improve the structural stability of the first driving member 210, thereby improving the driving stability of the first driving member 210 on the first transmission member 220.
[0038] Continue to refer to Figure 2 As shown, the disassembly device 200 also includes a second transmission member 250, which is connected to the first transmission member 220 and the first driving member 210.
[0039] In this embodiment, the first transmission member 220 and the first driving member 210 can be connected through the second transmission member 250, so as to realize the first driving member 210 driving the first transmission member 220.
[0040] Specifically, continue to refer to Figure 2 As shown, in this embodiment, the second transmission member 250 is a transmission belt, and the driving end of the first driving member 210 and the first transmission member 220 are both engaged with the transmission belt to achieve the transmission effect of the second transmission member 250 on the first transmission member 220.
[0041] Specifically, continue to refer to Figure 2As shown, in this embodiment, the first transmission component 220 is a lead screw, which is threadedly connected to the base 110. The disassembly device 200 includes two lead screws and two transmission belts. The two lead screws are spaced apart, and each lead screw is threadedly connected to the base 110. One transmission belt engages with the driving end of the first driving component 210 and one of the lead screws, while the other transmission belt engages with the driving end of the first driving component 210 and the other lead screw, so that the first driving component 210 can simultaneously drive the two lead screws. In this way, the base 110 can be driven simultaneously by the two lead screws, thereby further improving the directional accuracy of the base 110 moving along the first direction x and reducing the possibility of the screw 21 colliding with the extruder body 22.
[0042] Reference Figure 2 as well as Figure 4 As shown, the clamping device 100 also includes a disassembly aid 130, which is used to connect to the end of the screw 21 and is clamped between the clamping members 121 of any pair of clamping assemblies 120.
[0043] In this embodiment, when the screw 21 is disassembled, the initial position of the screw 21 is inside the extruder body 22. At this time, the screw 21 can be connected to the disassembly aid 130. When the screw 21 is connected to the disassembly aid 130, since the disassembly aid 130 is clamped between the clamping members 121 of any pair of clamping assemblies 120, when the base 110 moves along the first direction x, the screw 21 can be pulled along the first direction x by the disassembly aid 130, so that the screw 21 is gradually exposed outside the extruder body 22.
[0044] Specifically, in this embodiment, when the base 110 moves along the first direction x so that the screw 21 is at least partially exposed in the body 22 of the extruder, the first drive member 210 can stop driving the first transmission member 220, causing the base 110 to pause its movement along the first direction x. At the same time, the second drive member 122 drives the two symmetrically arranged clamping members 121 to move away from each other, so that the clamping assembly 120 can release its clamping on the disassembly auxiliary member 130. Subsequently, the first drive member 210 is reversed to drive the lead screw to reverse, so that the base 110 drives the clamping assembly 120 to move along the first direction x toward the body 22 of the extruder, so that the clamping assembly 120 can clamp the screw 21 itself. Furthermore, during the disassembly of the screw 21, the base 110 is moved back and forth along the first direction x so that the clamping assembly 120 can clamp the screw 21 at different positions, thereby facilitating the overall pulling of the screw 21 out of the extruder body 22 and realizing the disassembly of the screw 21 of the extruder.
[0045] Reference Figure 3 as well as Figure 4 As shown, the clamping assembly 120 also includes limiting members 123. Each clamping member 121 is provided with multiple limiting members 123, which protrude from the clamping member 121 and are oriented towards another clamping member 121. Therefore, when the extruder screw 21 is clamped between two clamping members 121, the multiple limiting members 123 provided on the clamping member 121 can be embedded between any two adjacent threads of the screw 21, so as to limit the screw 21 in the axial direction by the limiting members 123, thereby improving the clamping effect of the clamping assembly 120 on the screw 21.
[0046] Reference Figure 3 As shown, the limiting member 123 has a connecting portion 1231 and a limiting portion 1232. One end of the connecting portion 1231 is connected to the clamping member 121, and the other end of the connecting portion 1231 is connected to the limiting portion 1232. The cross-sectional area of the limiting portion 1232 gradually decreases in the direction away from the connecting portion 1231. In this way, when the limiting member 123 abuts against the surface of the spring, the limiting portion 1232 can abut against the surface of the spring. Since the cross-sectional area of the limiting portion 1232 gradually decreases in the direction away from the connecting portion 1231, the limiting portion 1232 can be better fitted between any two adjacent threads of the screw 21, reducing the damage of the limiting portion 1232 to the surface of the screw 21.
[0047] Reference Figure 3 as well as Figure 4 As shown, clamping member 121 has a clamping groove 1211 on one side facing the clamping member 121 symmetrically arranged thereto. Multiple limiting members 123 are disposed on the groove wall of clamping groove 1211 and protrude from the groove wall of clamping groove 1211. In this way, the extruder screw 21 can be clamped between the two clamping grooves 1211, so that the multiple limiting members 123 are embedded between any two adjacent threads of the screw 21.
[0048] Continue to refer to Figure 3 as well as Figure 4 As shown, the clamping groove 1211 is an arc-shaped clamping groove 1211, and multiple limiting members 123 are spaced apart along the circumference of the arc-shaped clamping groove 1211 on the groove wall of the clamping groove 1211. In this way, the shape of the clamping groove 1211 can be consistent with the shape of the screw 21, so as to increase the contact area with the screw 21 and thus improve the clamping capacity of the screw 21. At the same time, multiple limiting members 123 can be embedded between any two adjacent threads of the screw 21 along the circumference of the screw 21, thereby improving the limiting effect of the limiting members 123 on the screw 21 in the axial direction.
[0049] Reference Figure 4As shown, the clamping assembly 120 also includes an elastic element 124. The clamping member 121 has multiple receiving slots 1212, all of which communicate with the clamping slot 1211. Each receiving slot 1212 is provided with an elastic element 124. A limiting element 123 is at least partially inserted through the receiving slot 1212. Each limiting element 123 corresponds to one receiving slot 1212 and is at least partially inserted through it. One end of the elastic element 124 is connected to the wall of the receiving slot 1212, and the other end of the elastic element 124 is connected to the limiting element 123. When the limiting element 123 contacts the surface of the screw 21, the elastic element 124 can provide elastic displacement for the limiting element 123, so that the limiting element 123 can be adapted to screws 21 of different diameters. When the diameter of the screw 21 is small, the limiting member 123 can contact the surface of the screw 21 under the push of the elastic member 124. When the diameter of the screw 21 is large, the elastic member 124 can provide elastic displacement for the limiting member 123, avoiding interference between the surfaces of the limiting member 123 and the elastic member 124. Furthermore, the elastic movement of the elastic member 124 and the limiting member 123 can be guided by the receiving groove 1212, ensuring that the elastic member 124 and the limiting member 123 move in a preset direction.
[0050] Reference Figure 1 , Figure 5 as well as Figure 6 As shown, the fixing device 300 includes a first fixing component 310, which includes a support member 311 and a first fixing member 312. The support member 311 is provided with at least one limiting groove 3111, which is used to support at least a portion of the screw 21. The first fixing member 312 is connected to the end of the support member 311 away from the clamping component 120 along the first direction x.
[0051] In this embodiment, after the screw 21 is gradually pulled out of the extruder body 22, it can be placed in the limiting groove 3111 along the first direction x. The limiting groove 3111 limits the screw 21, reduces the rolling of the screw 21 in the circumferential direction, improves the fixing stability of the screw 21, and supports the screw 21 through the support member 311. Since the first fixing member 312 is connected to the end of the support member 311 away from the clamping assembly 120 along the first direction x, the fastener can connect the first fixing member 312 to the screw 21, thereby realizing the fixed connection between the screw 21 and the first fixing member 312, fixing the disassembled screw 21, and facilitating the cleaning and maintenance of the screw 21.
[0052] Specifically, in this embodiment, the limiting groove 3111 extends along the first direction x, and the shape of the groove wall of the limiting groove 3111 is consistent with the outer contour of the screw 21, so as to improve the stability of the screw 21 placed in the limiting groove 3111.
[0053] Specifically, refer to Figure 5 as well as Figure 6 As shown, the first fixing member 312 is provided with at least one first fixing hole 3121. The first fixing member 312 protrudes from the support member 311 at least partially along the second direction z toward the limiting groove 3111, and the first fixing hole 3121 is opened in the part of the first fixing member 312 that protrudes from the support member 311. In this way, when the screw is placed in the limiting groove 3111, the fastener can pass through the first fixing hole 3121 and connect with the screw, thereby realizing the fixed connection between one end of the screw and the first fixing member 312.
[0054] Reference Figure 5 As shown, the first fixing component 310 further includes a third driving member 313, which is connected to the support member 311 and is used to drive the support member 311 to move along the second direction z; wherein the second direction z is perpendicular to the first direction x.
[0055] It should be noted that the second direction z is Figure 1 The direction indicated by z in the middle.
[0056] In this embodiment, the support member 311 can be driven to move along the second direction z by the third driving member 313, so that the support member 311 can contact the screw 21, thereby realizing the supporting function of the support member 311 on the screw 21. At the same time, the support member 311 can support screws 21 of different diameters, avoiding interference between the support member 311 and the screw 21 during the movement of the screw 21.
[0057] Reference Figure 6 As shown, the fixing device 300 also includes a second fixing component 320, which includes a second fixing member 321. The second fixing member 321 is disposed at one end of the support member 311 near the clamping component 120 along the first direction x.
[0058] In this embodiment, since the second fixing member 321 is located near the clamping assembly 120 along the first direction x of the support member 311, the fastener can connect the second fixing member 321 to the screw 21, thereby achieving a fixed connection between the other end of the screw 21 and the second fixing member 321, so as to fix the screw 21 between the first fixing member 312 and the second fixing member 321, thereby improving the fixing effect on the screw 21 and facilitating the cleaning and maintenance of the screw 21.
[0059] Specifically, refer to Figure 7As shown, the second fixing member 321 is provided with at least one second fixing hole 3211. Therefore, when the screw is placed in the limiting groove 3111, the fastener can pass through the second fixing hole 3211 and connect with the screw, thereby achieving a fixed connection between one end of the screw and the second fixing member 321. Furthermore, the central axis of both the first fixing hole 3121 and the central axis of the second fixing hole 3211 extend along the first direction x. Therefore, when both ends of the screw 21 are fixed to the first fixing member 312 and the second fixing member 321 respectively, the connection stability between the screw 21 and the first fixing member 312 and the second fixing member 321 can be improved, thereby improving the fixing effect of the fixing device 300 on the screw 21.
[0060] Reference Figure 5 as well as Figure 6 As shown, the fixing device 300 also includes a connecting seat 330. The first fixing component 310 and the second fixing component 320 are both disposed on the connecting seat 330. The second fixing component 321 can move relative to the connecting seat 330 along the second direction z. Therefore, when the screw needs to be placed in the limiting groove 3111, the second fixing component 321 can move relative to the connecting seat 330 along the second direction z toward the direction away from the limiting groove 3111 to avoid the second fixing component 321 interfering with the placement of the screw. After the screw is placed, the second fixing component 321 can move relative to the connecting seat 330 along the second direction z toward the limiting groove 3111 so that the second fixing component 321 can be located at the end of the screw away from the first fixing component 312, so that the end of the screw away from the first fixing component 312 can be fixed on the second fixing component 321, thereby achieving the fixing of both ends of the screw.
[0061] Reference Figure 7 As shown, the second fixing component 320 further includes at least one mounting member 322, which is connected to the connecting seat 330 and disposed at the end of the first fixing member 312 away from the support member 311 along the first direction x. The second fixing member 321 is connected to the mounting member 322, and the mounting member 322 is movable relative to the connecting seat 330 along the second direction z.
[0062] In this embodiment, the second fixing member 321 and the connecting seat 330 can be connected by the mounting member 322. Since the mounting member 322 can move relative to the connecting seat 330 along the second direction z, when the mounting member 322 moves relative to the connecting seat 330 along the second direction z, the second fixing member 321 can be moved relative to the connecting seat 330 along the second direction z by the mounting member 322, thereby realizing the movement of the second fixing member 321 relative to the connecting seat 330.
[0063] Continue to refer to Figure 7As shown, the mounting component 322 is provided with a mounting hole 3221, which communicates with the second fixing hole 3211 and is coaxially arranged with the second fixing hole 3211.
[0064] In this embodiment, since the mounting hole 3221 is connected to and coaxially arranged with the second fixing hole 3211, when the screw 21 is fixed to the second fixing member 321, the screw 21 can pass through the mounting hole 3221, so as to avoid the mounting member 322 interfering with the connection between the screw 21 and the second fixing member 321.
[0065] Continue to refer to Figure 7 As shown, the second fixing component 320 also includes a plurality of positioning blocks 323, which are disposed on the wall of the mounting hole 3221 and protrude from the wall of the mounting hole 3221.
[0066] Specifically, in this embodiment, a drive motor is connected to one end of the screw 21 away from the first fixing member 312 along the first direction x, for driving the screw 21 to rotate inside the extruder, and the surface of the drive motor has a toothed groove.
[0067] In this embodiment, since multiple positioning blocks 323 are disposed on the wall of the mounting hole 3221 and protrude from the wall of the mounting hole 3221, when the end of the screw 21 away from the first fixing member 312 passes through the mounting hole 3221 along the first direction x, the positioning blocks 323 can be embedded in the toothed groove on the surface of the drive motor, so as to restrict the rotation of the drive motor along the circumferential direction by the positioning blocks 323, thereby restricting the rotation of the screw 21 along the circumferential direction and improving the fixing effect of the screw 21.
[0068] Reference Figure 5 As shown, the support member 311 is provided with multiple limiting grooves 3111, which are arranged in a row; the first fixing member 312 is provided with multiple first fixing holes 3121, which are arranged in a row; the second fixing component 320 includes multiple mounting members 322 and multiple second fixing members 321, which are arranged in a row, and each mounting member 322 is connected to a second fixing member 321; any two adjacent mounting members 322 are rotatably connected and can rotate relative to each other around the second direction z.
[0069] In this embodiment, since the support member 311 is provided with multiple limiting grooves 3111 arranged in a plurality of ways, multiple screws 21 can be supported simultaneously by the support member 311. Furthermore, since the first fixing member 312 is provided with multiple first fixing holes 3121, one end of multiple screws 21 can be fixed simultaneously by the first fixing member 312. Moreover, since the second fixing assembly 320 includes multiple mounting members 322 and multiple second fixing members 321 arranged in a plurality of ways, with each mounting member 322 connected to a second fixing member 321, the other end of multiple screws 21 can be fixed simultaneously by the multiple second fixing members 321. Furthermore, since any two adjacent mounting pieces 322 are rotatably connected and can rotate relative to each other around the second direction z, when the other ends of multiple screws 21 are simultaneously fixed by multiple second fixing pieces 321, the distance between any two screws 21 can be adjusted by rotating the mounting pieces, so that each screw 21 can be located in a limiting groove 3111, thereby improving the stability of the screw 21 in the limiting groove 3111 and improving the fixing effect of the screw 21.
[0070] Specifically, in this embodiment, any two adjacent mounting pieces 322 are hinged.
[0071] Reference Figure 6 As shown, the second fixing component 320 also includes a fourth driving member 324. The mounting member 322 is rotatably connected to the driving end of the fourth driving member 324. The mounting member 322 is able to rotate relative to the driving end of the fourth driving member 324 about the second direction z. The fourth driving member 324 is used to drive the mounting member 322 to move along the second direction z.
[0072] In this embodiment, the mounting member 322 can be driven to move along the second direction z by the fourth driving member 324, so that the second fixing member 321 can move relative to the connecting seat 330 along the second direction z, thereby realizing the connection between the screw 21 and the second fixing member 321. At the same time, since the mounting member 322 can rotate about the second direction z relative to the driving end of the fourth driving member 324, the rotation of the mounting member 322 about the second direction z can be realized, thereby realizing the adjustment of the distance between any two screws 21.
[0073] Reference Figure 5 As shown, the support member 311 is connected to the connecting seat 330. The support member 311 extends along the first direction x and is movable relative to the connecting seat 330 along the first direction x.
[0074] In this embodiment, since the support member 311 can move relative to the connecting seat 330 along the first direction x, when the support member 311 moves along the first direction x, the distance between the first fixing member 312 and the second fixing member 321 can be changed, so that the fixing device 300 can be adapted to the fixing requirements of screws 21 of different lengths.
[0075] Reference Figure 6 As shown, the second fixing component 320 also includes a fifth driving member 325. The second fixing component 321 is connected to the driving end of the fifth driving member 325. The fifth driving member 325 is used to drive the second fixing component 321 to move along the first direction x.
[0076] In this embodiment, the second fixing member 321 can be driven to move along the first direction x by the fifth driving member 325, thereby further changing the distance between the first fixing member 312 and the second fixing member 321, so that the fixing device 300 can be adapted to the fixing requirements of screws 21 of different lengths.
[0077] Specifically, refer to Figure 7 As shown, in this embodiment, the fixing device 300 further includes a plurality of third driving members 313, and the support member 311 has a plurality of support portions 3112. The plurality of support portions 3112 are arranged along the first direction x. Each third driving member 313 is used to drive a support portion 3112 to move along the second direction z. Each support portion 3112 is provided with a sub-limiting groove 3113. The plurality of sub-limiting grooves 3113 form a limiting groove 3111. The length of the limiting groove 3111 along the first direction x can be changed by changing the number of support portions 3112, so as to meet the support requirements of screws 21 of different lengths.
[0078] Reference Figure 1 , Figure 2 as well as Figure 6 As shown, the disassembly device 200 and the fixing device 300 are offset along the second direction z and along the first direction x, so that the disassembled screw 21 can be placed on the fixing device 300. The disassembly device 200 also includes a first support block 260, which is connected to the guide member 230 and is located on the side of the guide member 230 along the second direction z close to the fixing device 300. The fixing device 300 also includes a second support block 340, which is connected to the connecting seat 330 and is located on the side of the connecting seat 330 along the first direction x close to the disassembly device 200. The first support block 260 is supported on the second support block 340, so that the disassembly device 200 is supported by the second support block 340, thereby improving the structural stability of the disassembly device 200 and improving the stability of the screw 21 disassembly process.
