[0096] As shown in Figures 7-9 The packaging machine provided by the embodiment includes a conveying rotating wheel 8 connected to the frame 1, the conveying rotating wheel 8 has at least a feeding position, a folding position, an adhering position and a discharging position on the frame 1; a folding assembly 33 is rotatably installed on the frame and located at the folding position of the conveying rotating wheel 8, the folding assembly 33 is provided with a swingable first swing arm 35, the first swing arm 35 is connected with a first folding member 36, and the first folding member 36 is used to fold the first side edge of the paperboard; a folding assembly 34 is rotatably installed on the central shaft 39 of the conveying rotating wheel 8, the folding assembly 34 is provided with a swingable second swing arm 37, the second swing arm 37 is connected with a second folding member 38, and the second folding member 38 is used to fold the second side edge of the paperboard.

[0097] In use, the conveying wheel 8 conveys the paperboard to be packaged from the feeding station to the edge folding station, the first swing arm 35 is driven by the driving device to swing from the initial station to the edge folding station, the first bending piece 36 with the right angle opening is in contact with the corner of the product 9 to be packaged, the upper edge of the right angle opening is in contact with and presses against the upper side of the product 9 to be packaged, and the folding assembly 33 completes the folding of the first side edge; the second swing arm 37 is driven by the second transmission belt to swing from the bonding station to the edge folding station, the second bending piece 38 is in contact with the second side edge of the product 9 to be packaged, and the folding assembly 34 completes the folding of the second side edge; the folding assembly 33 is reset, and as the conveying wheel 8 rotates, the folding assembly 34 swings from the edge folding station to the bonding station, and the product 9 to be packaged slides from one end of the arc-shaped second bending piece 38 to the other end, continuously pressing against the second side edge, so as to realize the folding of the side edge of the product 9 to be packaged. Specifically, the second transmission belt can be a belt, a synchronous belt or a hinge, etc. In addition, as an alternative embodiment, the transmission belt can also be other rotary driving devices installed at the rotary connection of the second swing arm 37, such as a wheel chain rotary driving or a worm gear type rotary driving device, etc.

[0098] Specifically, as shown in Figure 10 , the central shaft 39 of the conveying wheel 8 is connected with a third transmission belt, the conveying wheel 8 is driven to rotate intermittently by the third transmission belt, and a plurality of clamping assemblies 40 are uniformly arranged on the central shaft 39 in the circumferential direction, the clamping assembly 40 has a fixed part 41 and a sliding part 42, the sliding part 42 is connected with a driving device, the sliding part 42 is driven to move towards the fixed part 41 by the driving device, so as to clamp the product 9 to be packaged; when the product 9 to be packaged is sent to the clamping assembly 40 at the feeding station, the side edge of the product 9 to be packaged protrudes outside the clamping assembly 40, which facilitates the folding and packaging of the side edge of the product 9 to be packaged at the subsequent station. In addition, as an alternative embodiment, the conveying wheel 8 can not be provided, and other linear conveying devices 65 that can operate the side edge of the product 9 to be packaged can be used.

[0099] As shown in Figure 11 , Figure 12As shown, a driving device is provided on the central shaft 39. The driving device is used to drive the clamping assembly 40 to slide along the axial direction of the central shaft 39. The clamping assembly is connected by multiple sets of belt drive structures 83. The belt drive structure 83 includes a bracket and a synchronous belt. The synchronous belt is disposed on the bracket and extends along the axial direction of the central shaft 39. The middle set of every three sets of clamping assemblies 40 is connected to the bracket. The two ends of the synchronous belt are respectively connected to a set of clamping assemblies 40 adjacent to the clamping assembly 40 on the bracket. The synchronous belt keeps the distance between the three sets of clamping assemblies 40 equal. Every three sets of clamping assemblies 40 are linked together by the belt drive structure 83. Two connected sets share a set of clamping assemblies 40, so that the clamping assemblies 40 are kept at equal intervals in pairs along the axial direction of the central shaft 39. Therefore, when clamping the product 9, the clamping position can be evenly arranged, and the clamping stability can be improved.

[0100] like Figure 13 As shown, in the packaging machine provided in this embodiment, the side sealing mechanism 5 includes: a crossbeam 43 arranged laterally along the side direction of the cardboard; a first mounting base 44 slidably connected to the crossbeam 43; a first tape mounting post 46 connected to the first mounting base 44, the first tape mounting post 46 being adapted to mount a roll of tape; and a first rotating wheel 45 connected to the first mounting base 44 and located on one side of the tape mounting post near the corner of the product 9 to be sealed, the first rotating wheel 45 pulling out the tape on the tape mounting post and adhering it to the product 9 to be sealed. On one side of the corner of the product 9 to be packaged; a first cutting blade 47, movably connected to the first mounting base 44, having a cutting head for cutting the pulled-out tape; a compaction roller 48 connected to the first mounting base 44 and located behind the first rotating wheel 45, the compaction roller 48 being a flexible wheel, the compaction surface of the compaction roller 48 being opposite to the corner of the product 9 to be packaged; when the compaction surface of the compaction roller 48 contacts the corner of the product 9 to be packaged, the compaction surface contacts both sides of the corner of the product 9 to be packaged.

[0101] In use, the adhesive tape roll is fixed on the first adhesive tape mounting column 46, and the adhesive tape is pulled out through the first rotating wheel 45. When the product 9 to be packaged moves to the packaging position, the first mounting seat 44 is driven to move downward by the up-down driving device, so that the side edge of the product 9 to be packaged contacts the first rotating wheel 45, and the adhesive tape is adhered to one side edge of the corner of the product 9 to be packaged. The compaction surface of the compaction roller 48 behind the first rotating wheel 45 contacts the corner of the product 9 to be packaged, and the compaction surface contacts the two side edges of the corner of the product 9 to be packaged respectively. With the first mounting seat 44 being pressed and sliding forward on the cross beam 43 parallel to the corner to be packaged, the adhesive tape is continuously pulled out, and the compaction roller 48 behind the first rotating wheel 45 compacts the adhesive tape. When the product 9 to be packaged moves to the front end, the cutter head on the first cutting knife 47 cuts off the adhesive tape, and the corner sealing machine is reset. The corner of the product 9 to be packaged is continuously sealed with the adhesive tape, and the adhesive tape is compacted and flat without wrinkles.

[0102] It should be further explained that the first rotating wheel 45 and the first adhesive tape mounting column 46 are further provided with a second rotating wheel 49. The second rotating wheel 49 is a metal wheel contacting the adhesive surface of the adhesive tape, so as to guide the adhesive tape to be pulled out and avoid the adhesive on the adhesive tape from adhering to the second rotating wheel 49. The first rotating wheel 45 is provided with an elastic pressing element 53. The adhesive tape passes through the gap between the elastic pressing element 53 and the first rotating wheel 45. The elastic force increases the friction between the adhesive tape and the first rotating wheel 45. When the adhesive tape is cut off, the adhesive tape can be prevented from retracting or adhering to other positions. In addition, as an alternative embodiment, the elastic pressing element 53 is not provided, and other clamping structures for preventing the adhesive tape from retracting after being cut off can be arranged below the first rotating wheel 45.

[0103] As shown in Figure 14 , the first adhesive tape mounting column 46 and the first rotating wheel 45 are connected to the first fixed plate 50. The first fixed plate 50 can be driven to move up and down by a moving device, so that the first rotating wheel 45 contacts one side edge of the product 9 to be packaged. The first cutting knife 47 is rotationally connected to the back of the first fixed plate 50. The first cutting knife cuts off the adhesive tape adhered to the side edge of the product 9 to be packaged. The first cutting knife 47 is connected with an elastic element. The elastic element is used to drive the first cutting knife 47 to deflect towards the side away from the adhesive tape. Specifically, the rotating shaft 26 of the first cutting knife 47 is connected with a torsional spring. The torsional spring is used to drive the first cutting knife 47 to rotate and move. In addition, as an alternative embodiment, the torsional spring can be replaced by other elastic devices, such as a tension spring connected to one side of the first cutting knife 47.

[0104] As shown in Figure 14 , Figure 15As shown, the first fixing plate 50 is movably connected to the second fixing plate 51. A first support column 52 is connected to the second fixing plate 51. When the first fixing plate 50 and the second fixing plate 51 move relative to each other, the first support column 52 cooperates with the first cutting blade 47. Through the relative movement of the first support column 52 and the first cutting blade 47, the first support column 52 drives the first cutting blade 47 to overcome the elastic force of the elastic member and deflect towards the side capable of cutting the tape. Specifically, when the moving device drives the first fixing plate 50 to move downwards, the first cutting blade 47 is moved downwards by the first fixing plate 50, while simultaneously being driven upwards by the elastic member, so that the upper edge of the first cutting blade 47 always rests against the first support column 52. When the moving device drives the first fixed plate 50 to move upward, the first cutting blade 47 is driven upward by the first fixed plate 50. At this time, due to the obstruction of the first support column 52, the first cutting blade 47 overcomes the elastic force of the elastic element and deflects downward, thereby causing the blade of the first cutting blade 47 to apply pressure to the tape and cut the tape.

[0105] like Figure 15 As shown, the compaction roller 48 is mounted on the second fixed plate 51, and a front-to-back moving device is mounted on the second fixed plate 51. The drive end of the front-to-back moving device is connected to the connecting plate 55. The lower half of the connecting plate 55 has an inclined surface that leans towards the first mounting base 44. A vertical moving device is mounted on the inclined surface, and the drive end of the vertical moving device is connected to the compaction roller 48. The vertical moving device drives the compaction roller 48 to reciprocate along the direction parallel to the bisector of the angle of the product 9 to be packaged, thereby making the compaction surface of the compaction roller 48 contact the corner of the product 9 to be coated with corner tape. The front-to-back moving device is used to adjust the distance between the compaction roller 48 and the pre-compression component 54.

[0106] like Figure 15As shown, in the packaging machine provided in this embodiment, a pre-compression component 54 is provided before the compaction roller 48. The pre-compression component 54 can be driven to move up and down by a vertical moving device, thereby moving closer to or away from the packaged product 9. The pre-compression component 54 includes a pre-compression roller and a support frame 32. The pre-compression roller is embedded in the support frame 32. The pre-compression roller has a rolling surface that contacts one side of the corner of the product 9 to be packaged, and the rolling surface forms the pre-compression surface. The pre-compression roller also has a flange protruding towards the other side of the corner of the product 9 to be packaged. In use, the rolling surface of the pre-compression roller pre-compresses the tape adhered to the upper side of the product 9, and the protruding flange on the pre-compression roller presses against the unbonded part of the tape to prevent the tape from curling. The support frame 32 has a lower surface for contacting one side of the corner of the product 9 to be packaged, which forms the pre-pressing surface. The support frame 32 also has an extension plate protruding toward the other side of the corner of the product 9 to be packaged, with the side of the extension plate facing the product 9 to be packaged forming the extension surface. Alternatively, as an alternative embodiment, the pre-pressing surface and the extension surface may be provided in only one set on the support frame 32 or the pre-pressing roller, or one of them may be provided on the support frame 32 and the pre-pressing roller respectively.

[0107] like Figure 15 As shown, in the packaging machine provided in this embodiment, the compacting roller 48 is mounted on the second fixed plate 51. A front-to-back moving device is mounted on the second fixed plate 51. The drive end of the front-to-back moving device is connected to a connecting plate 55. The lower half of the connecting plate 55 has an inclined surface that leans towards the first mounting base 44. A vertical moving device is mounted on the inclined surface, and the drive end of the vertical moving device is connected to the compacting roller 48. The vertical moving device drives the compacting roller 48 to reciprocate along the direction parallel to the bisector of the angle of the product 9 to be packaged, thereby causing the compacting surface of the compacting roller 48 to contact the corner of the product 9 to be coated with corner tape. The front-to-back moving device is used to adjust the distance between the compacting roller 48 and the pre-compression component 54. Specifically, the vertical moving device and the front-to-back moving device can be electrically driven or pneumatically driven, etc. Alternatively, as an alternative implementation, the vertical moving device and the front-to-back moving device can also be other linear drive devices such as electric push rods or pneumatic push rods.

[0108] like Figure 15 , Figure 16As shown, the packaging machine provided in this embodiment further includes: a first pressing device 56 connected to the first mounting base 44, the first pressing device 56 being driven by the first driving device 16 to press against one side of the corner of the product 9 to be packaged; and a second pressing device 57 connected to the crossbeam 43, the second pressing device 57 being driven by the second driving device 17 to press against the other side of the corner of the product 9 to be packaged.

[0109] When using, such as Figure 13 As shown, the first pressing device 56 is rotatably connected to the second fixed plate 51 via a rotating plate. A pressing wheel is mounted on one end of the rotating plate, and an elastic element is also connected to the rotating plate. The elastic element has an elastic force that drives the rotating plate to deflect away from the product 9 to be packaged. A second support column 58 that cooperates with the rotating plate is mounted on the first mounting base 44. The second support column 58 and the rotating plate move relative to each other through the relative movement of the second fixed plate 51 and the first mounting base 44. Specifically, a driving device is provided between the second fixed plate 51 and the first mounting base 44. Driven by the driving device, the second fixed plate 51 moves up and down relative to the first mounting base 44. When the second fixed plate 51 moves upward, the rotating plate deflects upward under the drive of the elastic element, thereby disengaging the pressing wheel from the product to be packaged 9, so as to press the edge of the next product to be packaged 9; when the second fixed plate 51 moves downward, the rotating plate moves downward following the second fixed plate 51, while the second pillar 58 does not move on the first mounting base 44. At this time, under the drive of the second pillar 58, the rotating plate deflects downward against the elastic force of the elastic element, thereby making the pressing wheel contact the outer edge of the corner of the product to be packaged 9.

[0110] like Figure 16 As shown, in the packaging machine provided in this embodiment, the second edge-pressing device 57 is connected to the crossbeam 43. The second edge-pressing device 57 is driven by a driving device to press against the other side of the corner of the product 9 to be packaged. During use, this prevents the product 9 from spreading out during tape application. Specifically, the second edge-pressing device 57 includes: an edge-pressing plate, which is mounted on an edge-pressing bracket. Both ends of the edge-pressing bracket are respectively mounted on the crossbeam 43 via vertical slides. A driving device is provided between the edge-pressing bracket and the crossbeam 43. Driven by the driving device, the edge-pressing plate is pressed downwards against the upper side of the product 9 to be packaged.

[0111] like Figure 17 , Figure 18As shown, the packaging machine provided by the embodiment comprises a base 78, a conveying device 65 mounted on the base 78, a second mounting seat 59 fixedly mounted on the base 78, the second mounting seat 59 being provided with a first work station and a second work station in sequence along the conveying device 65, the second mounting seat 59 being connected with a first ear folding piece 60, a second ear folding piece 61, a third edge folding piece 62, a pressing piece 64 and a fourth edge folding piece 63, the first ear folding piece 60, the second ear folding piece 61 and the third edge folding piece 62 being located at the first work station, and the pressing piece 64 and the fourth edge folding piece 63 being located at the second work station, the first ear folding piece 60 being used for folding a first ear folding part of the product 9 to be packaged, the second ear folding piece 61 being used for folding a second ear folding part of the product 9 to be packaged, the third edge folding piece 62 being used for folding an upper side edge of the product 9 to be packaged, the pressing piece 64 being used for pressing the upper side edge of the product 9 to be packaged, and the fourth edge folding piece 63 being used for folding a lower side edge of the product 9 to be packaged.

[0112] In use, the first ear folding member 60 has a bending part extending outwardly in the direction of the incoming product 9 to be packaged, which contacts and folds the first ear folding part of the end of the product 9 to be packaged. The second ear folding member 61 is an ear folding pusher rotatably connected to the base 78, which is connected to the second rotary driving device, and is driven to rotate by the second rotary driving device, thereby contacting and folding the second ear folding part of the product 9 to be packaged opposite the first ear folding part. The first and second edge folding members are connected to the up-and-down moving device, and in use, the first edge folding member is driven downward by the up-and-down driving device, contacts and folds the upper side edge of the product 9 to be packaged, and the second edge folding member is driven upward by the up-and-down driving device, contacts and folds the lower side edge of the product 9 to be packaged. Specifically, the up-and-down driving device can be an electric push rod or a pneumatic push rod driving device, etc. The pressing member 64 is slidably connected to the second mounting base 59, and is connected to the first horizontal driving device, which drives the pressing member 64 to move in the transverse direction. In order to facilitate folding, the product 9 to be packaged has a certain distance from the end edge folding structure, and in use, after the upper side edge of the product 9 to be packaged is folded, the pressing member 64 is moved toward the end of the product 9 to be packaged to press the upper side edge of the product 9 to be packaged. The second edge folding member is connected to the second horizontal driving device, which drives the second edge folding member to move in the transverse direction, and in use, after the lower side edge of the product 9 to be packaged is folded, the second edge folding member is moved toward the end of the product 9 to be packaged to press the lower side edge of the product 9 to be packaged. Thus, the end edge folding of the carton is realized mechanically. In addition, as an alternative embodiment, the first ear folding member 60 can also be a rotatable ear folding pusher arranged on the second mounting base 59 at a position corresponding to the first ear folding part of the product 9 to be packaged.

[0113] As Figure 19As shown, the packaging machine provided by the embodiment has the conveying device 65 which is a step conveying device 65 and has two groups arranged symmetrically left and right. Each group of the conveying device 65 has two groups of conveying frames 66 which make reciprocating linear motion in the front-back direction, and the two groups of conveying frames 66 are connected by connecting rods in adjustable spacing, so that the two groups of conveying frames 66 are kept in synchronization while the front-back distance can also be adjusted according to actual application. The conveying frame 66 is driven by a transmission belt to push the product 9 to be flanged from the initial position, sequentially pass through the first and second workstations of the end flanging structure, and then the conveying frame 66 returns to the initial position to convey the next product 9 to be packaged. In order to avoid the collision between the baffle 76 on the conveying frame 66 and the next product 9 to be packaged when it returns, the conveying frame 66 is connected with a sliding frame 69, the sliding frame 69 is connected with an up-down driving device, the sliding frame 69 is driven by the up-down driving device to move up and down, and the sliding frame 69 is used to directly contact the product 9 to be packaged. Specifically, the up-down driving device can be an electric drive or a pneumatic cylinder drive. In addition, as an alternative embodiment, the conveying device 65 can adopt a belt conveying device 65 or other ways which can realize horizontal linear conveying. Each group of the conveying device 65 can also be provided with only one conveying frame 66, so as to convey the products 9 to be packaged one by one.

[0114] As shown, Figure 20 , Figure 21 As shown, the packaging machine provided by the embodiment has the conveying device 65 which is a step conveying device 65 and has two groups arranged symmetrically left and right. Each group of the conveying device 65 has two groups of conveying frames 66 which make reciprocating linear motion in the front-back direction, and the two groups of conveying frames 66 are connected by connecting rods in adjustable spacing, so that the two groups of conveying frames 66 are kept in synchronization while the front-back distance can also be adjusted according to actual application. The conveying frame 66 is driven by a transmission belt to push the product 9 to be flanged from the initial position, sequentially pass through the first and second workstations of the end flanging structure, and then the conveying frame 66 returns to the initial position to convey the next product 9 to be packaged. In order to avoid the collision between the baffle 76 on the conveying frame 66 and the next product 9 to be packaged when it returns, the conveying frame 66 is connected with a sliding frame 69, the sliding frame 69 is connected with an up-down driving device, the sliding frame 69 is driven by the up-down driving device to move up and down, and the sliding frame 69 is used to directly contact the product 9 to be packaged. Specifically, the up-down driving device can be an electric drive or a pneumatic cylinder drive. In addition, as an alternative embodiment, the conveying device 65 can adopt a belt conveying device 65 or other ways which can realize horizontal linear conveying. Each group of the conveying device 65 can also be provided with only one conveying frame 66, so as to convey the products 9 to be packaged one by one.

[0115] In use, the slide frame 69 has two groups of tape rolls installed on the second tape mounting column 70 in sequence and at intervals along the conveying direction of the product 9 to be packaged. In use, after the tape is pulled out, the smooth surface of the tape without adhesive passes through two guide wheels 75, and then winds around the stretching wheel 81, so that the adhesive surface of the tape contacts the stretching wheel 81, and then passes through the clamping member 82 below the stretching wheel 81 to avoid the tape from retracting. In packaging, the third driving device 68 drives the slide frame 69 to slide on the third mounting seat 67 towards the product 9 to be packaged, so that the tape is attached to the end of the product 9 to be packaged, and the pressing wheel 74 of the pressing assembly 73 contacts and presses the tape on the end of the product 9 to be packaged. As the slide frame 69 moves towards the product 9 to be packaged, the pressing assembly 73 rotates on the slide frame 69, so that the pressing wheel 74 moves from the end of the product 9 to be packaged to the upper surface of the product 9 to be packaged to press and compact the tape. The pressing assembly 73 is connected to the stretching assembly 71 in linkage, when the tape is stretched to a sufficient length, the pressing assembly 73 drives the stretching assembly 71 to rotate on the slide frame 69 away from the product 9 to be packaged, so that the stretched section of the tape contacts the second cutting knife 72, and then the second cutting knife 72 cuts the stretched section of the tape, and finally the pressing wheel 74 compacts the tape, thereby completing the packaging of the end of the product 9 to be packaged with the tape.

[0116] Specifically, the pressing assembly 73 is connected to an elastic member, which has an elastic force to rotate the pressing assembly 73 towards the product 9 to be packaged. When the pressing assembly 73 contacts and presses against the product 9 to be packaged, the pressing assembly 73 rotates away from the product 9 to be packaged, and at this time, the elastic member has an elastic force to rotate the pressing assembly 73 towards the product 9 to be packaged. The elastic force makes the pressing wheel 74 press the tape. The elastic member can be a spring or a torsion spring, etc. Alternatively, the elastic member can be omitted, and other power devices can be used to drive the pressing assembly 73 to rotate, such as a motor, etc.

[0117] Further, the third mounting seat 67 is connected to a baffle 76 on the side close to the product 9 to be packaged. In use, the baffle 76 is attached to the side edge of the end of the product 9 to be packaged to avoid the end of the product 9 to be packaged from spreading during the packaging process. Alternatively, the baffle 76 can adopt other ways to press against the end of the product 9 to be packaged, such as a folding structure with a pressing member 64 that can move to the end packaging machine station along with the conveying.

[0118] Further, the third mounting seat 67 is slidingly connected to the base 78, and an up-down driving device is connected to the third mounting seat 67, the up-down driving device drives the third mounting seat 67 to vertically move on the base 78, adjusts the vertical height of the third mounting seat 67, so that the adhesive tape and the compacting rotating wheel can contact the end of the product 9 to be packaged, and the packaging is facilitated. The third mounting seat 67 has an adjusting seat and a base 77, the adjusting seat is slidingly connected to the base 77 in a horizontal direction, and a driving device is connected to the adjusting seat, the driving device drives the adjusting seat to horizontally move along the direction of the product 9 to be packaged, adjusts the horizontal position of the adjusting seat, and facilitates the adaptation to different products 9. Specifically, the up-down driving device can be a rotary driving device, for example, a gear type rotary driving device or a worm gear type rotary driving device, etc. In addition, as an alternative embodiment, the up-down driving device can also adopt other driving modes, for example, an electric push rod or a cylinder push rod driving device, etc.

[0119] As shown in Figure 22 , in the packaging machine provided by the embodiment, the rack 1 is provided with two mounting racks 79 arranged in parallel, the paperboard conveying mechanism 2, the product conveying mechanism 3, the side edge folding mechanism 4, the side edge packaging mechanism 5, the end edge folding mechanism 6 and the end edge packaging mechanism 7 are all mounted on the two mounting racks 79, and a distance adjusting device 80 is arranged between the two mounting racks 79, and the distance adjusting device 80 can adjust the interval distance between the two mounting racks 79.

[0120] In use, the distance adjusting device 80 can adjust the interval distance between the two mounting racks 79, and one-key adjustment is performed on the product 9 size to which the product conveying mechanism 3, the conveying rotating wheel 8, the end edge folding mechanism 6 and the end edge packaging mechanism 7 are adapted, so that the packaging machine can be used for packaging products 9 of various sizes. Specifically, one side of the mounting rack 79 is slidingly mounted, and the distance adjusting device 80 can drive the side of the mounting rack 79 to move close to the other side of the mounting rack 79. In addition, as an alternative embodiment, both sides of the mounting rack 79 can be slidingly mounted, and the distance adjusting device 80 can drive both sides of the mounting rack 79 to move to the middle.

[0121] Specifically, as shown in Figure 11 , Figure 23 , the clamping assembly 40 at the end of the conveying rotating wheel 8 away from the third transmission belt is connected to the sliding mounting rack 79, the clamping assembly 40 is slidingly connected to the central shaft 39, and the distance adjusting device 80 drives the sliding mounting rack 79 to move, thereby driving the clamping assembly 40 to move, the clamping assembly 40 is connected through the belt transmission structure 83, and the clamping assembly 40 is kept at equal intervals along the axial direction of the central shaft 39.
