Description

Technical Field

[0001] This application relates to the field of printing technology, and in particular to a belt guide correction component, a belt guide machine, and a printer. Background Technology

[0002] During inkjet printing, the printer uses a conveyor belt to transport the printing medium (such as fabric), which is driven forward by a drive roller and a driven roller. However, the conveyor belt cannot guarantee that it will move in a straight line on both sides during its movement; it will generally deviate to the left or right during the process. Currently, manual correction is used. However, in actual manual correction, both ends of the driven roller need to be adjusted separately, which is inconvenient, time-consuming, and labor-intensive. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a belt guide correction component, belt guide machine and printer, which can facilitate correction operation, save time and labor, and have a simpler overall structure, which helps to reduce equipment costs and facilitate maintenance.

[0004] This application provides the following technical solution: In a first aspect, embodiments of this application provide a guide strip correction component, the guide strip correction component comprising: Guide roller; A pair of mounting modules are provided at both ends of the guide roller. Each mounting module includes a mounting component and an adapter component. The adapter component and the mounting component are hinged together, which allows the adapter component to swing and rotate. The adapter component and the guide roller are slidably connected, and the guide roller can slide axially. The axis of the guide roller and the axis of rotation of the adapter component are collinear. An adjustment module is provided, wherein at least one of the mounting components of the mounting module is connected to the adjustment module, and the adjustment module is used to adjust the position of the corresponding mounting component in the adjustment direction so as to drive the mounting component and the guide roller to swing.

[0005] In some embodiments of the first aspect, the mounting member mates with the spherical joint of the adapter, enabling the adapter to swing and rotate with multiple degrees of freedom around a fixed sphere.

[0006] In some embodiments of the first aspect, the adapter has an axial through hole, and the end of the guide roller slides through the corresponding axial through hole of the adapter.

[0007] In some embodiments of the first aspect, at least one of the mounting modules further includes a first locking member disposed on the adapter, the first locking member enabling the guide roller to switch between a locked state and a free state.

[0008] In some embodiments of the first aspect, the first locking member includes a locking actuator, the adapter has two mounting positions, and the locking actuator can be selectively disposed in either of the mounting positions; when the locking actuator is disposed in one of the mounting positions, the locking actuator forms an abutment engagement with the guide roller to lock the guide roller; when the locking actuator is disposed in the other mounting position, the locking actuator is moved away from the guide roller to free the guide roller.

[0009] In some embodiments of the first aspect, the adjustment module includes an operating member, a second locking member, and a base member, the operating member being connected to the mounting member, and the operating member being movably disposed on the base member in the adjustment direction to drive the mounting member and the guide roller to swing. The second locking member is disposed on one of the operating member and the base member, and the second locking member is detachably connected to the other, so that the operating member can switch between a locked state and a free state.

[0010] In some embodiments of the first aspect, the operating member and the mounting member are threadedly connected to form a threaded transmission pair, and the operating member and the mounting member are rotatably connected, with the screw-in / screw-out direction of the mounting member parallel to the adjustment direction; The second locking member and the operating member are threadedly connected to form a helical transmission pair. The second locking member can abut against the base member to lock the position of the operating member so that the operating member is in a locked state.

[0011] In some embodiments of the first aspect, the adjustment module further includes a guide member that guides and engages with the mounting member to constrain the direction of movement of the mounting member such that the direction of movement of the mounting member is parallel to the adjustment direction.

[0012] Secondly, embodiments of this application also provide a belt guide machine, which includes a belt correction component as described in any of the above embodiments.

[0013] Thirdly, embodiments of this application also provide a printer, which includes the belt guide as described in the above embodiments.

[0014] The embodiments of this application have the following advantages: This application provides a belt guide correction assembly. The belt guide roller's two ends are hinged together by mounting modules (including mounting parts and adapters) to achieve swing and rotation functions. The adapter is slidably connected to the belt guide roller, allowing axial sliding of the roller, while its rotation axis is collinear with the roller's axis, ensuring synchronization during swing. When the belt deviates left or right during movement, an adjustment module (such as a screw or cylinder) pushes or pulls one of the mounting parts to move along the adjustment direction (e.g., horizontally). Because the mounting part is hinged to the adapter, the displacement of the mounting part is converted into the swing of the adapter, thereby changing the position of one end of the belt guide roller, altering the contact angle between the roller and the belt, and achieving automatic left-right correction of the belt. The mounting module at the other end of the belt guide roller adjusts accordingly, absorbing displacement through the sliding connection and hinge structure, ensuring the overall tilt angle of the belt guide roller is controllable and avoiding rigid interference.

[0015] Therefore, by automatically adjusting the guide roller angle via an adjustment module, the traditional method of manually adjusting both ends is replaced, significantly reducing operational complexity and saving time and effort. The modular design combining hinges and sliding joints reduces complex mechanical structures, lowers manufacturing costs, and facilitates maintenance and component replacement. The collinear design of the guide roller axis and the adapter's rotation axis ensures coordinated movement during the correction process, preventing guide belt twisting and improving correction stability and accuracy.

[0025] In related technologies, during inkjet printing, the printer uses a guide belt to transport the printing medium (such as fabric), which is driven forward by a drive roller and a driven roller. However, during the movement of the guide belt, it cannot be guaranteed that the left and right sides will move in a straight line; deviations usually occur during the movement. Currently, manual correction is used. However, in actual manual correction, both ends of the driven roller need to be adjusted separately, which is inconvenient, time-consuming, and labor-intensive.

[0026] As shown in Figure 1, Figure 2 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides a belt guide correction assembly. The belt guide correction assembly includes a belt guide roller 100, a pair of mounting modules 200, and an adjustment module 300. A mounting module 200 is respectively provided at both ends of the belt guide roller 100. Each mounting module 200 includes a mounting member 210 and a connecting member 220. The connecting member 220 and the mounting member 210 are hinged, allowing the connecting member 220 to swing and rotate. The connecting member 220 and the belt guide roller 100 are slidably connected, allowing the belt guide roller 100 to slide axially. The axis of the belt guide roller 100 and the rotation axis of the connecting member 220 are collinear. At least one mounting member 210 of the mounting module 200 is connected to the adjustment module 300. The adjustment module 300 is used to adjust the position of the corresponding mounting member 210 in the adjustment direction, thereby causing the mounting member 210 and the belt guide roller 100 to swing.

[0027] In these embodiments, this embodiment provides a guide belt correction component for automatically or semi-automatically correcting the running trajectory of the guide belt in an inkjet printer, so as to solve the problems of inconvenience, time and labor costs caused by manually adjusting the two ends of the driven roller in the prior art.

[0028] The guide roller 100 is a cylindrical metal roller with anti-slip textures or a rubber coating on its surface, used to support and drive the guide belt to run smoothly. Each end of the guide roller 100 is connected to a pair of mounting modules 200.

[0029] A mounting module 200 is provided at each end of the guide roller 100. Each mounting module 200 includes a mounting member 210 and an adapter member 220. For example, the mounting module 200 may be a universal ball bearing.

[0030] Mounting component 210 is a fixed bracket that is bolted to the printer frame and has a sliding groove or guide rail that allows it to slide in the adjustment direction.

[0031] The adapter 220 and the mounting member 210 are connected by a hinge structure. The hinge structure allows the adapter 220 to swing and rotate relative to the mounting member 210. Simultaneously, the adapter 220 and the guide roller 100 are slidably connected. For example, in this embodiment, the end of the guide roller 100 is provided with a splined shaft section, and the adapter 220 has a matching splined hole, allowing the guide roller 100 to slide freely axially within the adapter 220 while transmitting torque.

[0032] At least one mounting component 210 of the mounting module 200 is connected to an adjustment module 300. In this embodiment, both mounting components 210 are connected to the adjustment module 300 to achieve more precise bidirectional adjustment.

[0033] For example, the adjustment module 300 includes an adjustment screw and a drive element (such as a handwheel or a micro motor). One end of the adjustment screw is threadedly connected to the mounting member 210, and the other end is rotatably fixed to the frame. When the drive element is rotated, the adjustment screw causes the mounting member 210 to move in the adjustment direction. In an automated implementation, the drive element is a servo motor for automatic adjustment.

[0034] Based on one embodiment, this embodiment provides a simplified structure: the adjustment module 300 is installed on the module 200 on only one side (such as the right side), and the mounting part 210 on the other side (left side) is fixed to the frame.

[0035] When correction is needed, only the position of the right-side mounting piece 210 is adjusted, causing the guide roller 100 to swing as a whole. Although the degree of freedom of adjustment is slightly lower than that of double-sided adjustment, it can still effectively achieve the correction function, making it suitable for scenarios where high precision is not required, further simplifying the structure and reducing costs.

[0036] In other words, the guide roller 100 achieves swinging and rotation functions through hinged mounting modules 200 (including mounting parts 210 and adapter parts 220) at both ends. The adapter part 220 is slidably connected to the guide roller 100, allowing the guide roller 100 to slide axially, while its rotation axis is collinear with the axis of the guide roller 100, ensuring that the guide roller 100 maintains synchronization during swinging. When the guide belt deviates left or right during movement, the adjustment module 300 (such as a screw, cylinder, etc.) pushes or pulls one of the mounting parts 210 to move along the adjustment direction (such as the horizontal direction). Since the mounting part 210 is hinged to the adapter part 220, the displacement of the mounting part 210 is converted into the swinging of the adapter part 220, thereby causing a change in the position of one end of the guide roller 100, changing the contact angle between the guide roller 100 and the guide belt, and achieving automatic correction of the left and right position of the guide belt. The mounting module 200 at the other end of the guide roller 100 is adjusted accordingly. The displacement is absorbed by the sliding connection and hinge structure to ensure that the overall tilt angle of the guide roller 100 is controllable and to avoid rigid interference.

[0037] Therefore, the automatic adjustment of the guide roller 100 angle by the adjustment module 300 replaces the traditional manual adjustment of both ends, significantly reducing operational complexity and saving time and effort. The modular design combining hinges and sliding joints reduces complex mechanical structures, lowers manufacturing costs, and facilitates maintenance and component replacement. The collinear design of the guide roller 100 axis and the rotation axis of the adapter 220 ensures coordinated movement during the correction process, avoids guide belt twisting, and improves correction stability and accuracy.

[0038] In some embodiments, the mounting member 210 and the adapter 220 are spherically coupled, enabling the adapter 220 to swing and rotate with multiple degrees of freedom around a fixed sphere center.

[0039] In these embodiments, this application also provides an improved mounting module 200 structure, wherein the mounting member 210 and the adapter 220 are engaged by a spherical joint (also known as a "ball joint") to achieve more flexible and stable multi-degree-of-freedom motion.

[0040] In this embodiment, the mounting member 210 has a spherical groove on its inner side, which has a fixed spherical center. The adapter 220 has a ball head on its outer side that matches the spherical groove. The ball head is embedded in the spherical groove to form a spherical mating fit.

[0041] To prevent the ball head from coming out, an elastic retaining ring or retaining ring can be installed at the opening of the spherical groove, allowing the ball head to move freely within a certain angle range.

[0042] Through the spherical joint, the adapter 220 can perform multi-degree-of-freedom oscillation and rotational motion around the axis of the guide roller 100 with the center of the sphere as a fixed center. Specifically, when the adjustment module 300 drives the mounting component 210 to move in the adjustment direction, the spherical joint allows the adapter 220 to tilt the end of the guide roller 100 to achieve the oscillation angle required for correction. During operation, the torque of the guide roller 100 is transmitted through the adapter 220, and the spherical joint structure allows the adapter 220 to rotate synchronously with the guide roller 100 while maintaining the oscillation posture.

[0043] As mentioned above, the guide roller 100 and the adapter 220 are still connected by a sliding connection such as a spline or linear bearing, which allows the guide roller 100 to freely extend and retract in the axial direction to adapt to the slight changes in the distance between the two ends during the swinging process.

[0044] In some embodiments, the adapter 220 has an axial through hole, and the end of the guide roller 100 slides through the corresponding axial through hole of the adapter 220.

[0045] In these embodiments, this application also provides a preferred sliding connection structure for realizing axial sliding and torque transmission between the guide roller 100 and the adapter 220.

[0046] In this embodiment, the adapter 220 has an axial through hole extending through its body along the axial direction of the guide roller 100. The end of the guide roller 100 is machined into an adapting structure and slidably passes through the axial through hole of the adapter 220.

[0047] For example, the inner wall of the axial through hole is provided with an internal spline, and the outer periphery of the end of the guide roller 100 is provided with a matching external spline, forming a spline pair connection.

[0048] In other implementations, sliding connection and torque transmission can also be achieved by using a flat key + keyway, polygonal fit (such as hexagonal hole and hexagonal shaft), or linear bearing + optical shaft.

[0049] Alternatively, the axial through hole can be a smooth hole, and the end of the guide roller 100 can be a smooth shaft.

[0050] When the adapter 220 achieves multi-degree-of-freedom oscillation through the spherical pair, the sliding of the end of the guide roller 100 in the axial through hole can automatically compensate for the axial displacement caused by the oscillation, and realize the coordinated movement of the three degrees of freedom of oscillation, rotation and axial sliding.

[0051] In some embodiments, at least one mounting module 200 further includes a first locking member disposed on the adapter 220, the first locking member enabling the guide roller 100 to switch between a locked state and a free state.

[0052] In these embodiments, this application also provides an installation module 200 structure with switchable motion state, which realizes the switching between "locked state" and "free state" of the guide roller 100 on the adapter 220 by setting a first locking member.

[0053] In this embodiment, the first locking member (40) is disposed on the adapter 220 (22), specifically a radially disposed locking screw or an eccentric clamping mechanism.

[0054] The locking end of the first locking member can extend into the axial through hole and act on the outer periphery of the end of the guide roller 100 that passes through it.

[0055] When the first locking element is tightened, its locking end presses against the outer wall of the guide roller 100, generating frictional force, thereby restricting the sliding freedom of the guide roller 100 in the axial through hole, and causing the system to enter the "locked state".

[0056] When the first locking element is loosened, the locking end disengages from or maintains a gap with the outer wall of the guide roller 100, allowing the guide roller 100 to slide freely within the through hole, and the system returns to its "free state".

[0057] Initial installation and debugging mode (locked state) During equipment installation or maintenance, the first locking component can be tightened to form a relatively fixed connection between the guide roller 100 and the adapter 220. At this time, the guide roller 100 can be easily axially positioned, aligned, or disassembled as a whole, avoiding loosening or falling off of components due to sliding.

[0058] Normal operating mode (free state) After installation, loosen the first locking element to restore the axial sliding ability of the guide roller 100. At this time, the correction component can work normally: when the adjustment module 300 drives the mounting part 210 to move, the end of the guide roller 100 can slide within the adapter 220 to achieve overall swing correction.

[0059] Emergency Lock Mode (Locked State) During equipment shutdown or transportation, the first locking component can be locked to prevent the guide roller 100 from unnecessary axial movement due to vibration or external force, thereby improving safety.

[0060] Clearly, the state can be switched simply by tightening / loosening the screws, without the need for additional tools (if hand-tightening screws are used); the locking force acts directly on the outer periphery of the guide roller 100, with a large contact area and good anti-loosening effect; For example, the first locking element may also be an elastic pressure block + adjusting bolt, a wedge block mechanism, or an electromagnetic locking device.

[0061] Of course, a first locking element can be installed on both mounting modules 200 to achieve synchronous locking at both ends. Optionally, in an automated system, the first locking element can be driven by a pneumatic or electric actuator to achieve remote or automatic locking control.

[0062] In some embodiments, the first locking member includes a locking actuator, and the adapter 220 has two mounting positions, wherein the locking actuator can be selectively disposed in either of the mounting positions; when the locking actuator is disposed in one of the mounting positions, the locking actuator forms an abutment engagement with the guide roller 100 to keep the guide roller 100 in a locked state; when the locking actuator is disposed in the other mounting position, the locking actuator is moved away from the guide roller 100 to keep the guide roller 100 in a free state.

[0063] In these embodiments, this application also provides an improved first locking member structure, which, by setting two installation positions, allows the locking actuator to be installed in different positions, thereby realizing the mechanical switching between the "locked state" and the "free state" of the guide roller 100, avoiding frequent twisting operations, and improving operating efficiency and reliability.

[0064] In this embodiment, the locking actuator is a detachable or movable mechanical component, such as a metal block with a boss or pressure head, an eccentric wheel, or a slider. The adapter 220 has two mounting positions: First installation position: located in the radial direction of the axial through hole, and directly opposite the outer periphery of the guide roller 100; Second installation position: located on the side away from the axial through hole, or at a position offset from the radial line of action of the guide roller 100.

[0065] The locking actuator can be selectively installed in either the first or the second mounting position.

[0066] Locked State: When the locking actuator is installed in the first installation position, its pressure head or boss portion abuts against the outer peripheral surface of the guide roller 100, generating radial pressure and restricting the sliding freedom of the guide roller 100 within the axial through hole. At this time, the guide roller 100 is mechanically locked and cannot move axially, and the system is in the "locked state".

[0067] Free State: When the locking actuator is removed and reinstalled in the second mounting position, its pressure head is completely detached from the outer periphery of the guide roller 100 and does not contact the guide roller 100. At this time, the guide roller 100 can slide freely within the axial through hole, the system returns to the "free state", and the correction function is activated normally.

[0068] For example, the locking actuator can also be a locking screw. The adapter 220 is provided with a locking threaded hole 221 that communicates with the axial through hole. The state switching can be completed by using a tool to turn the locking screw, making the operation more intuitive and faster.

[0069] In some embodiments, the adjustment module 300 includes an operating member 310, a second locking member, and a base member 330. The operating member 310 is connected to the mounting member 210. In the adjustment direction, the operating member 310 is movably disposed on the base member 330 to drive the mounting member 210 and the guide roller 100 to swing.

[0070] The second locking member is disposed on one of the operating member 310 and the base member 330, and the second locking member is detachably connected to the other, so that the operating member 310 can switch between a locked state and a free state.

[0071] In these embodiments, this application also provides an adjustment module 300 structure with integrated locking function. By setting up an operating member 310, a base member 330 and a second locking member, the adjustability of the adjustment process and the position locking after the adjustment are completed are realized, so as to avoid adjustment failure caused by vibration during operation.

[0072] In this embodiment, the base component 330 is fixed to the support seat on the printer frame and is provided with a guide rail or slide groove extending in the adjustment direction. The operating element 310 is fixedly connected to the mounting element 210 (e.g., by bolts or welding) and is movably mounted on the base element 330; The operating element 310 and the base element 330 form a sliding pair, which allows the operating element 310 to slide relative to the base element 330 in the adjustment direction, thereby causing the mounting element 210 and the guide roller 100 to swing.

[0073] Furthermore, a second locking member is disposed on one of the operating member 310 or the base member 330 and is detachably connected to the other, for locking the sliding position of the operating member 310.

[0074] Free State (Adjustment State): When the second locking element is in the loose state (e.g., bolt loosened, snap released), the operating element 310 can slide freely on the guide rail of the base component 330. The operator or an automatic drive device (such as a motor) pushes the operating element 310 to move it in the adjustment direction, thereby changing the position of the mounting component 210, realizing the tilting and swinging of the guide roller 100, and completing the correction adjustment.

[0075] Locked State (Fixed State): After adjustment, tighten the second locking element (e.g., tighten the bolt, press down the locking handle) to press it against the contact surface between the operating element 310 and the base element 330, generating sufficient friction or mechanical interference to fix the relative position of the operating element 310 on the base element 330. At this time, the adjustment module 300 enters the "locked state" to prevent the adjustment position from drifting due to vibration or load changes during equipment operation.

[0076] Example, second locking member form: It can be a locking screw, an eccentric locking handle, a wedge-shaped pressure block mechanism, or a pneumatic / electromagnetic lock; If an eccentric handle is used, "quick locking / releasing" can be achieved without tools; One or more locking points can be set to ensure reliable locking.

[0077] The control element 310 can also be connected to the drive source through the lead screw nut 320 mechanism to achieve precise feeding. The second locking element is used to prevent reverse drive when the power is off or the machine stops. In the automation system, the second locking element can be an electromagnetic brake, which releases when energized and automatically locks when the power is off, improving safety. The base component 330 can be designed as a modular component, which is easy to replace or adapt to different models.

[0078] In some embodiments, the operating member 310 and the mounting member 210 are threadedly connected to form a threaded transmission pair, and the operating member 310 and the mounting member 210 are rotatably connected, with the screw-in and screw-out directions of the mounting member 210 parallel to the adjustment direction.

[0079] The second locking element and the operating rod are threaded together to form a helical transmission pair. The second locking element can abut against the base part 330 to lock the position of the operating element so that the operating element is in a locked state.

[0080] In these embodiments, this application also provides an adjustment module 300 structure that combines high-precision adjustment with reliable locking, wherein the operating member 310 and the mounting member 210 constitute a threaded transmission pair, and linear adjustment is achieved by rotation; at the same time, the second locking member and the operating member 310 constitute a helical transmission pair, which is used to press the base member 330 to achieve position locking.

[0081] For example, the connection method between the operating component 310 and the mounting component 210 is as follows: The operating element 310 is an adjusting rod (or "lead screw") with external threads; the mounting element 210 has a matching internal threaded hole; the threaded section of the operating element 310 is screwed into the threaded hole of the mounting element 210, forming a threaded transmission pair; at the same time, to prevent the mounting element 210 from rotating with the operating element 310, the two are also provided with a rotating connection structure, for example: The head of the operating element 310 is inserted into the corresponding groove of the mounting element 210, allowing rotation but restricting axial disengagement; or a thrust bearing is provided at the end of the operating element 310 to transmit axial force but allow relative rotation.

[0082] Adjusting the direction and transmission relationship: The direction of screwing in / out of the thread (i.e., the axial movement direction of the operating element 310) is parallel to the adjustment direction; When the control element 310 is rotated (e.g., using a wrench or handwheel), the control element 310 will move linearly along the axial direction because the mounting element 210 is restricted from rotation, thereby driving the mounting element 210 and the end of the guide roller 100 connected thereto to move in the adjustment direction, thus achieving the correction swing.

[0083] The locking mechanism of the second locking element: The second locking element is a locking nut 320 or a locking sleeve with internal threads; the outer periphery of the operating element 310 is provided with a second thread (or continuous with the first thread), and the second locking element is screwed onto the thread to form a helical transmission pair; the base element 330 is provided with a locking mating surface (such as a plane or annular shoulder). When locking is required, tighten the second locking member so that one end face of it abuts and presses against the locking mating surface of the base member 330, thereby "clamping" the operating member 310 onto the base member 330 and preventing it from moving in the adjustment direction, thus achieving the locking state. When adjustment is required, loosen the second locking member to disengage it from the base member 330, and the operating member 310 can then rotate freely and move axially, entering a free state.

[0084] Workflow Example Initial state: The second locking element is tightened, and the system is in the locked state.

[0085] Adjustment preparation: Loosen the second locking element to disengage it from the base element 330; Adjustment is performed by rotating the control component 310, which drives the mounting component 210 to move in the adjustment direction via a threaded transmission, thereby achieving the swing correction of the guide roller 100. Locking complete: After adjustment, keep the position of the operating part 310 unchanged, tighten the second locking part again to press it against the base part 330, and complete the position fixation.

[0086] For example, in this embodiment, the second locking member can also be a nut 320, the operating lever is a screw, the nut 320 is threadedly connected to the screw, and when locked, the nut 320 and the base member 330 abut and lock.

[0087] In some embodiments, the adjustment module 300 further includes a guide 340, which guides and mounts 210 to constrain the movement direction of the mounts 210, such that the movement direction of the mounts 210 is parallel to the adjustment direction.

[0088] In these embodiments, this application also provides an adjustment module 300 with a guide structure. By adding a guide member 340, the moving direction of the mounting member 210 is precisely constrained to ensure that it moves linearly along the preset adjustment direction (Y direction) and avoids deflection or shaking caused by uneven force or structural gaps.

[0089] In this embodiment, the guide 340 is fixed to the base 330 or directly integrated into the frame structure; the mounting 210 and the guide 340 form a guiding fit, so that the mounting 210 can only move in the adjustment direction.

[0090] For example, the specific implementation of the guide structure Sliding guide rail pair type: The guide component 340 is a linear guide rail (such as a dovetail guide rail, rectangular guide rail or rolling guide rail); the mounting component 210 is provided with a matching slider or groove; the mounting component 210 is sleeved on the guide rail by the slider to achieve high-precision linear guidance.

[0091] Guide shaft - linear bearing type: The guide component 340 is one or more guide shafts, fixed on the base component 330; the mounting component 210 is provided with a linear bearing or bushing; the mounting component 210 is sleeved on the guide shaft through the linear bearing to achieve low friction and high linearity sliding.

[0092] Obviously, the guide 340 forcibly constrains the movement trajectory of the mounting part 210, making its movement direction strictly parallel to the adjustment direction, avoiding the "skew" phenomenon caused by threaded transmission eccentricity or external force interference; reducing swaying and return error during movement, and improving the repeatability of the correction positioning accuracy; under the action of belt tension or external vibration, the guide 340 can bear part of the lateral force, reduce the load on the threaded pair or hinged structure, and extend its service life.
