The cloth rolling device comprises a machine base, a connecting assembly, a cloth rolling roller and a driving assembly. The connecting assembly comprises a sliding part and a rotating part, the sliding part is slidably arranged on the machine base in the first direction, and the rotating part is rotatably arranged on the sliding part around a first axis; the two connecting assemblies are arranged on the machine base in the second direction in a spaced mode. The two ends of the cloth rolling roller are rotationally connected with the rotating pieces of the two connecting assemblies respectively; the driving assembly is arranged on the machine base and used for driving the two connecting assemblies to move relative to the machine base in the first direction.

Description

Technical Field

[0001] This application relates to the field of digital printing technology, and more particularly to a fabric rolling device. Background Technology

[0002] When digital printing equipment is in operation, pressure is first applied to the printing medium by a rolling device to lay it flat and adhere it to the printing guide belt. Then, the printing guide belt transports the printing medium to the printing position for printing. The rolling device includes a rolling roller, both ends of which are slidably connected to the machine base via sliders and guide rails. A transmission mechanism synchronously drives the two sliders to slide relative to the machine base, thereby driving the rolling roller to roll along the printing guide belt. This continuously applies pressure to the printing medium without generating lateral forces parallel to the printing medium, reducing the likelihood of wrinkles on the printing medium.

[0003] Due to processing and assembly errors, the sliding processes of the two sliders are often asynchronous, causing the rolling roller to deflect relative to the machine base. This, in turn, results in the slider being subjected to a deflection force relative to the guide rail. The deflection force on the slider increases the friction between the slider and the guide rail, leading to slider slippage or even jamming, resulting in a high failure rate of the rolling device. Summary of the Invention

[0004] The embodiments of this application aim to provide a rolling device that can at least improve the problem of high failure rate of rolling devices.

[0006] In some embodiments, the connecting assembly further includes a connector slidably disposed on the rotating member along the second direction, and the two ends of the rolling roller are respectively rotatably connected to the connectors of the two connecting assemblies.

[0007] In some embodiments, the connector is provided with a sliding shaft, the rotating member is provided with a sliding hole, the sliding shaft is at least partially disposed in the sliding hole, and both the sliding shaft and the sliding hole extend along the second direction.

[0008] In some embodiments, the sliding shaft is located on the side of the connector opposite to another of the connecting components, and the sliding hole extends to the side facing the connector.

[0009] In some embodiments, the connecting assembly further includes a guide rod, a slide block, and a first driver. The guide rod is disposed on the connecting member and extends along a third direction. The slide block is slidably disposed on the guide rod. Both ends of the rolling roller are rotatably connected to the slide blocks of the two connecting assemblies, respectively. The first driver is disposed on the connecting member and is drively connected to the slide block. The first driver is used to drive the slide block to slide along the guide rod.

[0010] In some embodiments, the first driver includes a drive shaft and a drive housing, the drive housing being used to drive the drive shaft to move axially; one end of the drive shaft extends toward the pressing direction of the rolling roller and is connected to the slide; the connecting assembly further includes an elastic element and a first adjusting element, the other end of the drive shaft extending out of the drive housing and connected to the first adjusting element, the elastic element being supported between the first adjusting element and the drive housing.

[0011] In some embodiments, the rolling device further includes a sensor disposed on the machine base for detecting the position of the slider relative to the machine base; and / or, the rolling device further includes a buffer disposed on the machine base, with two buffers located on opposite sides of the slider along the first direction to limit the slider to a safe range of movement.

[0012] In some embodiments, the drive assembly includes a drive shaft, a pulley structure, and a second driver. The drive shaft is rotatably mounted on the base. The two pulley structures are respectively driven to both ends of the drive shaft and are respectively driven to the two sliding members. The second driver is mounted on the base and is used to drive the drive shaft to rotate so as to drive the two sliding members to slide synchronously relative to the base.

[0013] In some embodiments, the pulley structure includes a first pulley, a second pulley, and a synchronous belt. The first pulley is disposed on the drive shaft, the second pulley is rotatably disposed on the base, and the synchronous belt is tensioned between the first pulley and the second pulley. The synchronous belt includes a tensioning section extending along the first direction, and the tensioning section is connected to the rotating member. The base includes two first mounting plates, which are spaced apart along the second direction. Both ends of the drive shaft are rotatably connected to the two first mounting plates.

[0015] In the rolling device of this application embodiment, a rotating member is rotatably disposed on a sliding member, allowing the sliding member to rotate relative to the rolling roller about a first axis. When the two sliding members slide asynchronously relative to the machine base, the rolling roller deflects relative to the machine base about the first axis, while the sliding member can rotate relative to the rolling roller about the first axis, preventing the sliding member from deflecting synchronously with the rolling roller about the first axis. This improves the problem of increased sliding friction between the sliding member and the machine base due to deflection force, which can lead to slippage or even jamming of the sliding member, thus reducing the failure rate of the rolling device.

[0025] Firstly, please refer to Figure 1 This application provides a rolling device 100, which includes a base 1, a connecting component 2, a rolling roller 3, and a driving component 4. The base 1 is used to mount the connecting component 2 and the driving component 4. The connecting component 2 is used to slidably mount the rolling roller 3 on the base 1 along a first direction X. The driving component 4 is used to drive the rolling roller 3 to move relative to the base 1 along the first direction X.

[0026] In some embodiments, please refer to Figure 1 The rolling device 100 also includes a printing guide belt 5. A rolling roller 3 is used to lay and adhere the printing media to the printing guide belt 5. Exemplarily, the printing guide belt 5 includes at least a section extending along a first direction X, the rolling roller 3 presses the printing media against this section of the printing guide belt 5, and the rolling roller 3 moves along the first direction X under the drive of the drive assembly 4, thereby laying and adhering the printing media to the printing guide belt 5. It is understood that the printing guide belt 5 has adhesive to adhere the printing media. In some other embodiments, the printing guide belt 5 may not be part of the rolling device 100; for example, the printing guide belt 5 may be a component of the printer, or a structure independent of the printer and the rolling device 100.

[0027] In some embodiments, please refer to Figure 2 The base 1 includes a support plate 11 for supporting the printing guide belt 5. Optionally, the support plate 11 is parallel to the first direction X and the second direction Y, and the rolling roller 3 is located on one side of the support plate 11 along the third direction Z.

[0028] Among them, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0029] In some embodiments, please refer to Figure 2 The base 1 includes two side plates 12 spaced apart along the second direction Y. The two ends of the support plate 11 are connected to the two side plates 12 respectively. Thus, the support plate 11 and the two side plates 12 are connected to form a whole, which can both support the printing guide belt 5 and connect the two support plates 11 to each other.

[0030] In some embodiments, please refer to Figure 2 The base 1 includes a sliding mounting plate 13, which is slidably connected to the connecting assembly 2. Optionally, the sliding mounting plate 13 is disposed on the side plate 12, for example, it is detachably mounted to the side plate 12 by screws.

[0031] In some embodiments, please refer to Figure 2The base 1 includes a first mounting plate 14 and a second mounting plate 15, which are used to mount the drive assembly 4. Optionally, the first mounting plate 14 is disposed on the side plate 12, for example, and is detachably mounted to the side plate 12 by screws. Optionally, the second mounting plate 15 is disposed on the side plate 12, for example, and is detachably mounted to the side plate 12 by screws. Optionally, along the first direction X, the first mounting plate 14 and the second mounting plate 15 are respectively located on both sides of the sliding mounting plate 13.

[0032] For connection component 2 mentioned above, please refer to Figure 3 and Figure 4 The connecting component 2 includes a slider 21, which is slidably disposed on the base 1 along a first direction X. For example, the sliding mounting plate 13 is provided with a guide rail 131, which extends along the first direction X, and the slider 21 is provided with a slider 211, which is slidably connected to the guide rail 131 to slidably dispose the slider 21 on the base 1.

[0033] Two connecting components 2 are spaced apart on the base 1 along the second direction Y. A driving component 4 is located on the base 1 and drives the two connecting components 2 to move relative to the base 1 along the first direction X. Specifically, the driving component 4 can drive the two sliders 211 of the two connecting components 2 to move relative to the base 1 along the first direction X. The two ends of the rolling roller 3 are respectively connected to the sliders 21 of the two connecting components 2, so that the rolling roller 3 can move with the sliders 21 along the first direction X. When the two sliders 21 slide asynchronously relative to the base 1, the rolling roller 3 deflects relative to the base 1 about a first axis. The first axis is parallel to the third direction Z. This causes the sliders 21 to be subjected to a deflection force relative to the base 1. The deflection force on the sliders 21 increases the friction between the sliders 211 and the guide rails 131 of the base 1, which in turn causes the sliders 211 to slide and even get stuck, resulting in a high failure rate of the rolling device 100.

[0034] In some embodiments, please refer to Figure 4 The sliding mounting plate 13 is provided with a baffle 132, which is located on the side of the guide rail 131 facing the other connecting component 2. That is, the baffle 132 is located between the printing guide belt 5 and the guide rail 131, and is used to block debris such as lint and yarn on the printing guide belt 5 and the printing medium. It can also be used to block ink and glue, and improve the problem that the slider 211 slides along the guide rail 131 due to contamination of the guide rail 131, which increases the friction and even causes the slider 211 to get stuck on the guide rail 131.

[0035] In some embodiments, please refer to Figure 4 and Figure 5The connecting component 2 also includes a rotating member 22, which is rotatably disposed on the sliding member 21 about a first axis. The two ends of the rolling roller 3 are respectively rotatably connected to the rotating members 22 of the two connecting components 2. For example, the sliding member 21 is provided with a rotating shaft 212, and the rotating member 22 is provided with a rotating hole 221. The rotating shaft 212 is rotatably engaged with the rotating member 22 through the rotating hole 221. For example, a bearing is provided between the rotating shaft 212 and the inner wall of the rotating hole 221, and both the rotating shaft 212 and the rotating hole 221 extend along a third direction Z, thereby rotatably disposing the rotating member 22 on the sliding member 21 about a first axis. The two ends of the rolling roller 3 can be respectively connected to the two rotating members 22 through bearings, so that the rolling roller 3 is rotatably connected to the rotating member 22.

[0036] The rotating component 22 is rotatably mounted on the sliding component 21, allowing the sliding component 21 to rotate relative to the rolling roller 3 about a first axis. When the two sliding components 21 slide asynchronously relative to the machine base 1, the rolling roller 3 deflects relative to the machine base 1 about the first axis, while the sliding component 21 rotates relative to the rolling roller 3 about the first axis, preventing the sliding component 21 from deflecting synchronously with the rolling roller 3 about the first axis. This improves the problem of increased sliding friction between the sliding component 21 and the machine base 1 due to deflection force, which can lead to the sliding component 21 becoming stuck or even jammed, thus reducing the failure rate of the rolling device 100.

[0037] In some embodiments, please refer to Figure 4 and Figure 5The connecting assembly 2 further includes a connector 23, which is slidably disposed on the rotating member 22 along the second direction Y. Both ends of the rolling roller 3 are rotatably connected to the connectors 23 of the two connecting assemblies 2. Exemplarily, the connector 23 has a sliding shaft 231, and the rotating member 22 has a sliding hole 222. The sliding shaft 231 is at least partially disposed within the sliding hole 222, and both the sliding shaft 231 and the sliding hole 222 extend along the second direction Y. Both ends of the rolling roller 3 can be connected to the two connecting members 23 via bearings, thereby rotatably connecting the rolling roller 3 to the connecting members 23. The sliding shaft 231 can slide within the sliding hole 222, thereby allowing the connecting member 23 to slide relative to the rotating member 22 along the second direction Y. It should be noted that the two guide rails 131 connected to the two sliders 21 are not strictly parallel. Due to production and assembly errors, the distance between the two guide rails 131 is not constant, causing variations in the pressure exerted by the slider 211 on the guide rails 131. Consequently, the frictional force of the slider 211 changes continuously as it slides along the guide rails 131, leading to jamming or even complete stoppage. In this embodiment, the connecting member 23 can slide relative to the rotating member 22 in the second direction Y. As a result, the distance between the two sliders 211 of the two connecting components 2 changes synchronously with the change in the distance between the two guide rails 131. This makes the frictional force of the slider 211 more uniform as it slides along the guide rails 131, improving the problem of jamming or even complete stoppage, and making the sliding speed of the slider 211 more stable. It is understandable that the connector 23 is provided with at least two sliding shafts 231 and the rotating part 22 is provided with at least two sliding holes 222, with one sliding shaft 231 corresponding to one sliding hole 222, thereby improving the problem of the rotating part 22 rotating around the sliding shaft 231.

[0038] In some embodiments, the sliding shaft 231 is located on the side of the connector 23 opposite to another connecting component 2, and the sliding hole 222 extends to the side facing the connector 23. See also... Figure 3 The two connecting components 2 are mirror-symmetrically arranged along the second direction Y. That is, in the two connecting components 2, the sliding shaft 231 is located outside the two connecting parts 23, and the sliding hole 222 is located inside the two rotating parts 22, thereby preventing the sliding shaft 231 from disengaging from the sliding hole 222. No additional limiting structure is needed to achieve sliding limitation between the connecting parts 23 and the rotating parts 22, simplifying the structure of the connecting components 2 and facilitating their assembly and disassembly.

[0039] In some embodiments, please refer to Figure 6The connecting component 2 further includes a guide rod 24, a slide 25, and a first driver 26. The guide rod 24 is disposed on the connecting member 23 and extends along the third direction Z. The slide 25 is slidably disposed on the guide rod 24. The two ends of the rolling roller 3 are rotatably connected to the slides 25 of the two connecting components 2 respectively. The first driver 26 is disposed on the connecting member 23 and is drively connected to the slide 25. The first driver 26 is used to drive the slide 25 to slide along the guide rod 24. Exemplarily, the connecting member 23 includes a first connecting plate 232 and two second connecting plates 233. The two second connecting plates 233 are spaced apart from the first connecting plate 232 along the third direction Z. The slide 25 has a hole. The two ends of the guide rod 24 pass through the hole of the slide 25 and are respectively connected to the two second connecting plates 233 to slidably dispose of the slide 25 on the connecting member 23. The two ends of the rolling roller 3 can be connected to the two slides 25 respectively through bearings to rotatably connect the rolling roller 3 to the slides 25. The first driver 26 can drive the rolling roller 3 to move relative to the base 1 along the third direction Z, realizing the rising and falling of the rolling roller 3. The falling of the rolling roller 3 means that it moves towards the support plate 11 to press the printing medium onto the printing guide belt 5; the rising of the rolling roller 3 means that it moves away from the support plate 11, creating a gap between the rolling roller 3 and the printing guide belt 5, facilitating the placement of the printing medium between them. It is understood that the connecting assembly 2 includes at least two guide rods 24, and the slide 25 has at least two holes, with one guide rod 24 corresponding to one hole, thereby improving the problem of the slide 25 rotating around the guide rods 24. Optionally, the first driver 26 is a cylinder.

[0040] In some embodiments, please refer to Figure 6The first driver 26 includes a drive shaft 261 and a drive housing 262. The drive housing 262 is used to drive the drive shaft 261 to move axially. One end of the drive shaft 261 extends toward the pressing direction of the rolling roller 3 and is connected to the slide 25. The connecting assembly 2 also includes an elastic element 27 and a first adjusting element 28. The other end of the drive shaft 261 extends out of the drive housing 262 and is connected to the first adjusting element 28. The elastic element 27 is supported between the first adjusting element 28 and the drive housing 262. Exemplarily, the middle part of the drive shaft 261 is located inside the drive housing 262, and both ends of the drive shaft 261 extend out of the drive housing 262 in a direction parallel to the third direction Z. The end of the drive shaft 261 facing the support plate 11 is connected to the slide 25, and the end of the drive shaft 261 away from the support plate 11 is connected to the first adjusting element 28. Thus, the elastic element 27 applies an elastic force away from the support base to the drive shaft 261. When the first driver 26 stops working, the elastic element 27 drives the rolling roller 3 to rise, thereby mitigating the problem of the rolling roller 3 suddenly falling and hitting the operator when the printing media is placed between the rolling roller 3 and the printing guide belt 5 due to the first driver 26 unexpectedly stopping. Furthermore, the elastic element 27 counteracts the force exerted by the first driver 26 on the rolling roller 3 to press down on the support plate 11, mitigating the problem of excessive pressure from the rolling roller 3 on the printing media. Optionally, the elastic element 27 is a straight spring.

[0041] In some embodiments, the first adjusting member 28 is threadedly connected to the drive shaft 261. The first adjusting member 28 is used to adjust the position of the first adjusting member 28 relative to the drive shaft 261 in the third direction Z when rotating relative to the drive shaft 261. By rotating the first adjusting member 28, the degree of compression of the elastic member 27 can be adjusted, thereby adjusting the pressure of the rolling roller 3 on the printing medium. Optionally, the first adjusting member 28 is a bolt.

[0042] In some embodiments, please refer to Figure 3 and Figure 4The rolling device 100 also includes a sensor 6, which is disposed on the base 1. The sensor 6 is used to detect the position of the slider 21 relative to the base 1. For example, the sensor 6 is a photoelectric switch, and the slider 21 is provided with a trigger 213, which is a light-blocking plate. When the trigger 213 moves with the slider 21 to a position opposite to the sensor 6, the sensor 6 is triggered, thereby detecting the position of the slider 21 relative to the base 1. In another example, the sensor 6 is a magnetic switch, and the trigger 213 is a magnetic contact. When the trigger 213 moves with the slider 21 to a position opposite to the sensor 6, the magnetic field strength detected by the sensor 6 reaches a preset trigger value and triggers, thereby detecting the position of the slider 21 relative to the base 1. In this case, there are two sensors 6, which are spaced apart along a first direction X. Two sensors 6 can confine the slider 21 within a preset movement range. For example, whenever sensor 6 is triggered, the driving direction of the control device changes, so that the slider 21 always moves between the two endpoints, confining the slider 21 within this movement range, which is the preset movement range. The preset movement range can be changed by adjusting the position of sensor 6 on the base 1. Specifically, the trigger 213 can be moved with the slider 21 to a position opposite to sensor 6. Then, the magnetic field strength detected by sensor 6 at this time is recorded as the reference trigger value, and the preset trigger value is updated to the reference trigger value, thus setting the preset trigger value. The preset trigger value can be appropriately increased based on the above reference trigger value, for example, by 1% or 2%, so that the preset trigger value is slightly larger than the reference trigger value, thereby improving the reliability of sensor 6. By confining the slider 21 within the preset movement range, the problem of the slider 21 disengaging from the guide rail 131 or colliding with other parts of the rolling device 100 is improved.

[0043] In some embodiments, please refer to Figure 3 and Figure 7 The rolling device 100 also includes buffer members 7, which are disposed on the base 1 along the first direction X. Two buffer members 7 are located on either side of the slider 21 to limit the slider 21 to a safe range of movement. When the slider 21 moves to contact the buffer member 7, the buffer member 7 can absorb the impact force of the slider 21, improving the problem of the slider 21 being damaged by impact and detaching from the guide rail 131. Optionally, the buffer member 7 is made of a material with elastic elements 27, such as rubber or silicone. It is understood that a safe range of movement is formed by the slider 21 contacting the two buffer members 7 respectively. The preset range of movement is within the safe range, so that when the sensor 6 fails, the buffer member 7 provides a second layer of safety, further improving the problem of the slider 21 detaching from the guide rail 131 or impacting other parts of the rolling device 100. Optionally, the two buffer members 7 are respectively disposed on the first mounting plate 14 and the second mounting plate 15.

[0044] In some embodiments, please refer to Figure 3 The drive assembly 4 includes a drive shaft 41, pulley structures 42, and a second driver 43. The drive shaft 41 is rotatably mounted on the base 1. The two pulley structures 42 are respectively connected to both ends of the drive shaft 41 and are respectively connected to two sliding members 21. The second driver 43 is mounted on the base 1 and is used to drive the drive shaft 41 to rotate, thereby causing the two sliding members 21 to slide synchronously relative to the base 1. Exemplarily, the base 1 includes two first mounting plates 14, which are spaced apart along a second direction Y. Both ends of the drive shaft 41 are rotatably connected to the two first mounting plates 14. The first mounting plates 14 may have holes, and bearings are provided between the inner wall of the holes and the drive shaft 41, thereby rotatably connecting the drive shaft 41 to the first mounting plates 14. The second driver 43 drives the transmission shaft 41 to rotate, thereby driving the two pulley structures 42 to move synchronously. This, in turn, drives the two connecting components 2 to move synchronously relative to the base 1 along the first direction X. This improves the synchronicity of the sliding of the two connecting components 2 relative to the base 1, reduces the deflection force on the sliding member 21, and mitigates the problem of increased sliding friction between the sliding member 21 and the base 1 due to the deflection force, which could lead to the sliding member 21 getting stuck or even jammed. This reduces the failure rate of the rolling device 100. Optionally, the second driver 43 can be a motor, servo motor, etc.

[0045] For the pulley structure 42 described above, please refer to Figure 7 The pulley structure 42 includes a first pulley 421, a second pulley 422, and a synchronous belt 423. The first pulley 421 is located on the drive shaft 41, the second pulley 422 is rotatably located on the machine base 1, and the synchronous belt 423 is tensioned between the first pulley 421 and the second pulley 422. The synchronous belt 423 includes a tensioning section extending along the first direction X, and the tensioning section is connected to the rotating member 22. Exemplarily, the second pulley 422 is rotatably mounted on the second mounting plate 15 via bearings; the two ends of the synchronous belt 423 pass over the first pulley 421 and the second pulley 422 respectively, and the portion of the synchronous belt 423 located between the first pulley 421 and the second pulley 422 is tensioned to tension the synchronous belt 423 between the first pulley 421 and the second pulley 422; the first pulley 421 and the second pulley 422 are spaced apart along the first direction X, so that the tensioned portion located between the first pulley 421 and the second pulley 422 is parallel to the first direction X, that is, the synchronous belt 423 includes a tensioned section extending along the first direction X; the connecting assembly 2 also includes a fixing member 29, which is disposed on the rotating member 22 and is fixedly connected to the tensioned section of the synchronous belt 423. When the drive shaft 41 drives the first pulley 421 to rotate, the tensioned section moves along the first direction X, thereby causing the sliding member 21 to slide relative to the base 1 along the first direction X.

[0046] In some embodiments, please refer to Figure 4 The fixing member 29 includes a first fixing plate 291 and a second fixing plate 292, which clamp the tensioning section of the synchronous belt 423. Optionally, the first fixing plate 291 and the second fixing plate 292 can be fixed relative to each other by screws. Optionally, the first fixing plate 291 and the rotating member 22 can be detachably connected by angle brackets and screws. Optionally, the trigger member 213 is disposed on the second fixing plate 292.

[0047] In some embodiments, please refer to Figure 8 The drive assembly 4 also includes two limiting rings 44, which are respectively sleeved on both ends of the drive shaft 41. The two limiting rings 44 abut against the inner sides of the two first mounting plates 14, and are used to adjust their positions on the drive shaft 41. The inner sides of the two first mounting plates 14 are the sides of each first mounting plate 14 facing the other. For example, the limiting rings 44 have threaded holes, and bolts are threaded through these holes. The bolts abut against the drive shaft 41, thereby limiting the axial position of the limiting rings 44 along the drive shaft 41. By simultaneously adjusting the positions of the two limiting rings 44 on the drive shaft 41, the position of the drive shaft 41 relative to the base 1 in the second direction Y is adjusted. The first pulley 421 is mounted on the drive shaft 41, thereby adjusting the position of the first pulley 421 relative to the base 1 in the second direction Y. By adjusting the position of the pulley relative to the machine base 1 along the second direction Y, the position of the end of the synchronous belt 423 closest to the first pulley 421 relative to the machine base 1 along the first direction X can be adjusted. This, in turn, adjusts the parallelism between the synchronous belt 423 and the guide rail 131, improving the problem of increased friction between the slider 211 and the guide rail 131 caused by the poor parallelism between the synchronous belt 423 and the guide rail 131. Optionally, a bearing is provided between the drive shaft 41 and the first mounting plate 14. The outer ring of the bearing is fixed to the first mounting plate 14, the inner ring of the bearing is sleeved on the drive shaft 41, and the limiting ring 44 abuts against the inner ring of the bearing.

[0048] In some embodiments, please refer to Figure 7 and Figure 9The base 1 includes a second mounting plate 15, a tensioning member 16, and a second adjusting member 17. The tensioning member 16 is slidably disposed on the second mounting plate 15 along a first direction X. The second adjusting member 17 is rotatably disposed on the second mounting plate 15. The second adjusting member 17 is threadedly connected to the tensioning member 16. The second adjusting member 17 is used to drive the tensioning member 16 to move relative to the second mounting plate 15 along the first direction X when rotating. The second pulley 422 is rotatably disposed on the tensioning member 16. For example, the second mounting plate 15 has a groove 151 on one side along the second direction Y, and a strip hole 152 at the bottom of the groove 151. Both the groove 151 and the strip hole 152 extend along the first direction X. One end of the tensioning member 16 is located inside the groove 151. A screw passes through the strip hole 152 from the outside of the second mounting plate 15 and is connected to the tensioning member 16 so that the tensioning member 16 is slidably disposed on the second mounting plate 15 along the first direction X. The second mounting plate 15 has a through hole 153 on the side away from the first pulley 421. The through hole 153 extends along the first direction X to the groove 151. The second adjusting member 17 passes through the through hole 153 from the outside of the second mounting plate 15 and is threadedly connected to the tensioning member 16. The second adjusting member 17 abuts against the side of the second mounting plate 15 away from the first pulley 421. When the second adjusting member 17 is rotated, it translates relative to the tensioning member 16 along the first direction X. However, due to the constraint of the second mounting plate 15, the second adjusting member 17 cannot move towards the first pulley 421. Therefore, the distance between the first pulley 421 and the second pulley 422 can be adjusted by rotating the second adjusting member 17, thereby adjusting the tension of the synchronous belt 423. Optionally, the second adjusting member 17 is a bolt, with the bolt head abutting against the side of the second mounting plate 15 opposite to the first pulley 421. Alternatively, the second adjusting member 17 can be rotatably mounted on the second mounting plate 15, in which case the through hole 153 can also be located on the side of the second mounting plate 15 facing the first pulley 421.
