[0032] Please refer to Figure 1 And Figure 2 The roller mechanism 100 includes a cylinder assembly 10, a connecting assembly 20 and a sliding assembly 30. The cylinder assembly 10 includes a first sleeve piece 11 and a second sleeve piece 12 connected by a piston. The connecting assembly 20 includes a first connecting piece 21 and a second connecting piece 22, both of which include a rotatingly connected outer ring 211 and an inner ring 212. The first sleeve piece 11 is sleeved on the outer ring 211 of the first connecting piece 21 and is in interference fit with the outer ring 211 of the first connecting piece 21. The second sleeve piece 12 is sleeved on the outer ring 211 of the second connecting piece 22 and is in interference fit with the outer ring 211 of the second connecting piece 22. The sliding assembly 30 includes a loading piece 31 and a sliding piece 32. The inner ring 212 of the first connecting piece 21 is sleeved on the loading piece 31 and is in interference fit with the loading piece 31. The loading piece 31 is provided with a receiving groove 311 and a first gas inlet hole 312 in communication. The inner ring 212 of the second connecting piece 22 is sleeved on the sliding piece 32 and is in interference fit with the sliding piece 32. The sliding piece 32 is inserted into the receiving groove 311 and airtightly abuts against the groove wall of the receiving groove 311, so as to divide the receiving groove 311 into a first space 3111 and a second space 3112. The sliding piece 32 is provided with a second gas inlet hole 321. The first gas inlet hole 312 and the second gas inlet hole 321 are in communication with the first space 3111 and the second space 3112, respectively. The first gas inlet hole 312 is used for conveying gas to the first space 3111 to drive the sliding piece 32 to move the second sleeve piece 12 away from the first sleeve piece 11. The second gas inlet hole 321 is used for conveying gas to the second space 3112 to drive the sliding piece 32 to move the second sleeve piece 12 close to the first sleeve piece 11. Exemplarily, the first connecting piece 21 and the second connecting piece 22 can be ball bearings.
[0033] The roller mechanism 100 and the conveying device 200 described above, when in actual use, when the width dimension of the conveying belt 201 is increased, the first air inlet hole 312 delivers gas to the first space 3111, so that the sliding member 32 drives the second connecting member 22 and the second sleeve member 12 to move away from the first sleeve member 11, so that the length of the first sleeve member 11 inserted into the second sleeve member 12 decreases, and then the length of the first sleeve member 11 and the second sleeve member 12 between the first connecting member 21 and the second connecting member 22 increases, so as to adapt to the conveying belt 201 with the increased width dimension, when the width dimension of the conveying belt 201 is decreased, the second air inlet hole 321 delivers gas to the second space 3112, so that the sliding member 32 drives the second connecting member 22 and the second sleeve member 12 to move close to the first sleeve member 11, so that the length of the first sleeve member 11 inserted into the second sleeve member 12 increases, and then the length of the first sleeve member 11 and the second sleeve member 12 between the first connecting member 21 and the second connecting member 22 decreases, so as to adapt to the conveying belt 201 with the decreased width dimension. In this way, the first air inlet hole 312 and the second air inlet hole 321 respectively deliver gas to the first space 3111 and the second space 3112 to drive the sliding member 32 to drive the second sleeve member 12 to move away from or close to the first sleeve member 11, so that the length of the first sleeve member 11 and the second sleeve member 12 between the first connecting member 21 and the second connecting member 22 increases or decreases, and then adapts to the conveying belt 201 with different dimensions, improves the flexibility of use, and reduces the production cost.
[0034] In addition, the outer ring 211 and the inner ring 212 of the first connecting member 21 are respectively in interference fit with the first sleeve member 11 and the loading member 31, so that the loading member 31 can drive the first sleeve member 11 to slide synchronously through the first connecting member 21, the outer ring 211 and the inner ring 212 of the second connecting member 22 are respectively in interference fit with the second sleeve member 12 and the sliding member 32, so that the sliding member 32 can drive the second sleeve member 12 to slide synchronously through the second connecting member 22, and since the outer ring 211 and the inner ring 212 are rotationally connected, the first sleeve member 11 and the second sleeve member 12 can rotate relative to the loading member 31 and the sliding member 32.
[0035] Please refer to Figure 2 In some embodiments, the loading member 31 and the sliding member 32 are both provided with annular grooves 313 away from one end of the receiving groove 311, the annular groove 313 of the loading member 31 is arranged along the circumference of the loading member 31 and receives the inner ring 212 of the first connecting member 21, the annular groove 313 of the sliding member 32 is arranged along the circumference of the sliding member 32 and receives the inner ring 212 of the second connecting member 22, and the annular groove 313 adjacent to the groove wall of the receiving groove 311 is used to abut against the inner ring 212 to limit the position of the inner ring 212.
[0036] Thus, by setting the annular groove 313, when the first connecting piece 21 and the second connecting piece 22 are assembled to the loading piece 31 and the sliding piece 32 respectively, the annular groove 313 receives the inner ring 212, and the annular groove 313 abuts against the inner ring 212 through the groove wall adjacent to the receiving groove 311, so that the annular groove 313 limits the installation position of the inner ring 212, and ensures that the first connecting piece 21 and the second connecting piece 22 are stably assembled to the preset position of the loading piece 31 and the sliding piece 32 respectively.
[0037] Referring to Figure 3 In some embodiments, the loading piece 31 comprises a main body 314 and a cover 315, the main body 314 is provided with the receiving groove 311 at one end facing the sliding piece 32, and the other end of the main body 314 is provided with the first air inlet hole 312 extending to the groove bottom of the receiving groove 311 along the extension direction of the main body 314, the cover 315 is detachably connected to the main body 314 and is provided with a through hole 3151 in communication with the receiving groove 311, and the sliding piece 32 is movably arranged in the through hole 3151 and extends into the receiving groove 311.
[0038] Thus, by detachably connecting the main body 314 and the cover 315, the loading piece 31 forms a split structure, which facilitates the assembly of the sliding piece 32 to the loading piece 31 and simplifies the assembly operation.
[0039] Referring to Figure 2 and Figure 3 In some embodiments, the sliding piece 32 comprises a sliding body 322 and a piston body 323, the inner ring 212 of the second connecting piece 22 is sleeved on the sliding body 322 and is in interference fit with the sliding body 322, the sliding body 322 is movably arranged in the through hole 3151, the second air inlet hole 321 is formed in the sliding body 322, the piston body 323 is in airtight abutment with the groove wall of the receiving groove 311 and is detachably connected with the sliding body 322, and the piston body 323 is used to divide the receiving groove 311 into a first space 3111 and a second space 3112. Specifically, the second air inlet hole 321 is formed in the end of the sliding body 322 away from the receiving groove 311 and extends to the side wall of the sliding body 322 located in the receiving groove 311.
[0040] Thus, by setting the specific structure of the sliding piece 32, the sliding body 322 and the piston body 323 form a split connection structure, which facilitates the stable assembly of the sliding body 322 and the piston body 323 to the loading piece 31 by the operator.
[0041] Referring to Figure 3In some embodiments, the sliding member 32 further comprises a resisting body 324, which is arranged in a spaced manner with the piston body 323 along a direction in which the sliding body 322 points to the first connecting member 21 and is connected with the sliding body 322, and the orifice of the second air inlet hole 321 in the receiving groove 311 is located between the resisting body 324 and the sliding body 322, and the resisting body 324 is used to abut against the groove bottom of the receiving groove 311 away from the first connecting member 21 to limit the sliding body 322.
[0042] In this way, by arranging the above-mentioned resisting body 324, when the sliding body 322 drives the second sleeve member 12 to move away from the first sleeve member 11, the resisting body 324 abuts against the groove bottom of the receiving groove 311 away from the first connecting member 21, thereby limiting the movement distance of the sliding body 322, avoiding the orifice of the second air inlet hole 321 moving out of the receiving groove 311 away from the second connecting member 22, and further ensuring the repeated operation of the drum mechanism 100.
[0043] Please refer to Figure 2 In some embodiments, the drum mechanism 100 further comprises two supporting members 40, which are respectively detachably connected with the loading member 31 and the sliding member 32 away from one end of the receiving groove 311, and are used to support the loading member 31 and the sliding member 32.
[0044] In this way, by arranging the above-mentioned two supporting members 40, the two supporting members 40 are arranged to support the loading member 31 and the sliding member 32 respectively, thereby preventing the loading member 31 and the sliding member 32 from rotating with the rotation of the first sleeve member 11 and the second sleeve member 12, and facilitating the normal operation of the drum mechanism 100.
[0045] Please refer to Figure 2 and Figure 3 In some embodiments, the loading member 31 and the sliding member 32 are both provided with a limiting groove 316 at one end away from the receiving groove 311, and the two limiting grooves 316 are used to clamp the corresponding supporting members 40 respectively.
[0046] In this way, by arranging the two limiting grooves 316 to clamp the corresponding supporting members 40 respectively, the loading member 31 and the sliding member 32 are arranged to be clamped and connected with the corresponding supporting members 40 respectively, thereby facilitating the quick disassembly and assembly of the two supporting members 40.
[0047] Please refer to Figure 2In some embodiments, the support 40 comprises a support body 41 and a mounting body 42, the support body 41 is provided with an open slot 411 and a clearance hole 412, the open slot 411 is arranged on the side of the support body 41 away from the receiving slot 311, the clearance hole 412 is arranged on the bottom of the open slot 411 and communicates with the open slot 411, the sliding member 32 and the loading member 31 are respectively arranged in the corresponding clearance hole 412 and extend to the corresponding open slot 411, the support bodies 41 of the two supports 40 respectively support the loading member 31 and the sliding member 32, and the mounting body 42 is connected with the support body 41 and is used for mounting the support body 41 to an external device.
[0048] In this way, by arranging the specific structure of the support 40, the sliding member 32 and the loading member 31 are respectively arranged in the corresponding clearance hole 412 and extend to the corresponding open slot 411, so that the sliding member 32 and the loading member 31 do not protrude out of the open slot 411 and interfere with the external device connected with the mounting body 42.
[0049] Please continue to refer to Figure 2 In some embodiments, the first sleeve body 111 comprises a sleeve body 111 and a connecting body 112, the sleeve body 111 is sleeved on the outer ring 211 of the first connecting member 21 and is connected with the connecting body 112, the connecting body 112 is movably arranged in the second sleeve member 12, the cross-sectional area of the sleeve body 111 is equal to the cross-sectional area of the second sleeve member 12 and is greater than the cross-sectional area of the connecting body 112.
[0050] In this way, by arranging the cross-sectional area of the sleeve body 111 equal to the cross-sectional area of the second sleeve member 12, the sleeve body 111 of the first sleeve member 11 and the second sleeve member 12 abut the transmission belt 201 at the same time, so that the sleeve body 111 and the second sleeve member 12 cannot stably support the transmission belt 201 due to the inconsistent size, and by arranging the cross-sectional area of the sleeve body 111 greater than the cross-sectional area of the connecting body 112, the connecting body 112 is movably arranged in the second sleeve member 12, so as to ensure the clearance fit between the second sleeve member 12 and the connecting body 112 and prevent the friction between the second sleeve member 12 and the connecting body 112 when the second sleeve member 12 moves relative to the connecting body 112.
