Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically a laminating machine for producing laminating mesh fabric. Background Technology

[0002] Currently, space mesh composite materials have been widely used in various fields, such as as waterproof membranes for pool walls or bottoms, as materials for kayak manufacturing, or as air cushion membranes for various air cushion products. When used as air cushion membranes for various air cushion products, the air cushion is prone to bursting due to excessive local stress during inflation, thus rendering the air cushion product unusable. Therefore, users will perform post-processing when using it.

[0003] To increase strength, reinforcement sheets are added to both sides of a conventional space mesh composite material. Specifically, adhesive is applied, and then the reinforcement sheets are manually attached, requiring a laminating machine. The mesh with the reinforcement sheets is then placed on a heating roller for heating and flattening, bonding them together. The mesh passes between the adhesive blanket and the heating roller, and is compressed by the high temperature of the adhesive blanket and the heating roller, causing changes in its fiber structure, thereby eliminating internal stress and achieving the purpose of preventing shrinkage. However, the pressure between the adhesive blanket and the heating roller is often not adjustable, so the shrinkage rate of the mesh cannot be adjusted. Especially when processing long and thin strips of mesh, the mesh is prone to bending or wavy deformation, and wrinkles are easily generated during lamination.

[0004] Chinese Patent CN221392335U discloses a mesh fabric bonding and pressing machine, including a bonding frame. The bonding frame is equipped with a mesh fabric feeding component, a transport component, and a mesh fabric ironing component. The mesh fabric ironing component includes a rubber roller, a heating roller, and two opposing mounting brackets. The two mounting brackets are fixedly connected to both sides of the bonding frame. One side of each mounting bracket extends outward and is fixed with a support plate. The bottom of each support plate is hinged with a movable plate, and the top of each support plate is equipped with a cylinder. The output ends of the two cylinders pass through the two support plates and are movably connected to the top of the two movable plates. The two ends of the heating roller are movably connected to the two movable plates, and the two ends of the rubber roller are movably connected to the two mounting brackets. By adjusting the distance between the heating roller and the rubber roller, the heating roller is always in contact with the mesh fabric surface, which increases the pressure on the mesh fabric to a certain extent, smooths out the wrinkles on the mesh fabric surface, and further improves the bonding quality of the mesh fabric.

[0005] The utility model describes in its specification that "the mesh fabric feeding assembly includes a fixed frame 9, a roll roller 10, and two opposing limiting collars 11. The fixed frame 9 is fixedly connected to the top of the bonding frame 1. The two ends of the roll roller 10 are movably connected to the two sides of the fixed frame 9, and an adjustable speed mechanism is provided at the end of the roll roller 10 away from the fixed frame 9. The two limiting collars 11 are respectively encircled at both ends of the roll roller 10. The adjustable speed mechanism includes a fixed plate 12, a movable seat 13, a drive motor 14, a first small gear 15, a first large gear 16, and a limiting member. The fixed plate 12 is fixedly connected to the outer wall of the fixed frame 9. The first small gear 15 and the first large gear 16 are respectively encircled at the end of the roll roller 10 away from the fixed frame 9. The limiting member is fixedly connected to the top of the fixed plate 12, and the movable seat 13 is movably connected to the limiting member. The drive motor 14..." 4 is fixedly connected to the top of the movable seat 13, and the output end of the drive motor 14 is fixedly connected to the shaft 17. The surface of the shaft 17 is respectively provided with a second small gear 23 and a second large gear 24. The second large gear 24 meshes with the first small gear 15, and the second small gear 23 meshes with the first large gear 16. The limiting component includes a base plate 18, a smooth rod 19 and a threaded rod 20. The base plate 18 is fixedly connected to the fixed plate 12. The four corners of the top of the base plate 18 are respectively provided with fixed posts 21. The smooth rod 19 and the threaded rod 20 pass through the bottom of the movable seat 13 and two opposite fixed posts 21 respectively. The smooth rod 19 is fixedly connected to the fixed posts 21 and is movably connected to the bottom of the movable seat 13. The threaded rod 20 is movably connected to the fixed posts 21 through ball bearings and is threadedly connected to the bottom of the movable seat 13.

[0006] "By rotating the threaded rod 20, the movable seat 13 slides on the smooth rod 19, and the movable seat 13 drives the drive motor 14 to move. When the second small toothed disc 23 meshes with the first large toothed disc 16, the teeth of the second large toothed disc 24 will move away from the tooth groove of the first small toothed disc 15, and the rotation speed of the winding roller 10 will change accordingly, which facilitates the adjustment of the feeding speed of the mesh to a certain extent."

[0007] In this novel speed-regulating mechanism, the drive motor is moved by rotating a threaded rod during speed adjustment. The drive motor then moves a shaft, which in turn moves the second small gear disc and the second large gear disc. When the second small gear disc moves towards the first large gear disc, it is prone to chipping teeth on the first large gear disc. Similarly, when the second large gear disc moves towards the first small gear disc, it is prone to chipping teeth on the first small gear disc. This leads to accelerated wear on the first small gear disc, the first large gear disc, the second small gear disc, and the second large gear disc, shortening their service life.

[0008] Therefore, this utility model proposes a technical solution to solve the problem that the speed regulating mechanism is prone to gear breakage during speed regulation, which leads to accelerated wear and shortened service life. Utility Model Content

[0009] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pressing machine for producing laminated mesh fabric. The speed adjustment mechanism will not experience tooth breakage during the speed adjustment process, and will not accelerate the wear of the first small toothed disc, the first large toothed disc, the second small toothed disc, and the second large toothed disc, thereby achieving the technical effect of non-destructive speed adjustment.

[0010] A laminating machine for producing laminated mesh fabric includes a laminating frame, on which a mesh fabric feeding component, a transport component, and a mesh fabric ironing component are provided. The transport component is located between the mesh fabric feeding component and the mesh fabric ironing component. The mesh fabric feeding component includes a fixed frame, a roll roller, an adjustable speed mechanism, and two opposing limiting rings. The adjustable speed mechanism includes a top plate, a bottom plate, a first large gear, a first small gear, a second large gear, a second small gear, a first motor, a drive shaft, and two rotating tubes.

[0011] The base plate is fixed to the bottom end of the outer wall of the fixing frame, the top plate is fixed to the top end of the outer wall of the fixing frame, and three spaced vertical plates are fixed to the bottom end of the top plate. One end of the roll roller is fixed with a rotating shaft that is concentric and coaxial with it. The other end of the rotating shaft passes through the fixing frame and the three vertical plates in sequence, and is rotatably connected to the fixing frame and the three vertical plates through bearings. The first motor is installed at the top end of the base plate, one end of the drive shaft is fixedly connected to the output shaft of the first motor, and the other end of the drive shaft is rotatably connected to the fixing frame through bearings.

[0012] The two rotating tubes are rotatably connected between two adjacent vertical plates via bearings, and are both sleeved on the outside of the rotating shaft. The rotating tubes are concentric and coaxial with the rotating shaft, and there is a gap between their inner sidewalls and the outer sidewalls of the rotating shaft. The rotating tubes are provided with fixing components for fixing the rotating tubes to the rotating shaft.

[0013] The first large gear and the first small gear are both fixedly sleeved on the outside of the drive shaft. The second large gear and the second small gear are respectively fixedly sleeved on the outside of the two rotating tubes. The first large gear meshes with the second small gear, and the first small gear meshes with the second large gear.

[0014] By adopting the above technical solution, when it is necessary to adjust the sending speed of the mesh fabric through the speed regulating mechanism, one rotating tube is fixed to the rotating shaft by operating the fixing component, while the other rotating tube is released from the rotating shaft. After the first motor is started and drives the drive shaft to rotate, the drive shaft drives the first large gear and the first small gear to rotate. The first large gear drives the second small gear to rotate, and the first small gear drives the second large gear to rotate. The second small gear and the second large gear respectively drive the two rotating tubes to rotate. The rotating tube fixed to the rotating shaft can drive the rotating shaft to rotate synchronously, while the rotating tube released from the rotating shaft only rotates between the two vertical plates and has no effect on the rotating shaft. When the rotating shaft is driven by the second large gear, the rotation speed of the rotating shaft is relatively slow, and when the rotating shaft is driven by the second small gear, the rotation speed of the rotating shaft is relatively fast.

[0015] The speed regulation mechanism of this invention will not experience tooth breakage during the speed regulation process, and will not accelerate the wear of the first small gear plate, the first large gear plate, the second small gear plate, and the second large gear plate, thus achieving a lossless speed regulation effect.

[0016] A further feature of this invention is as follows: the fixing component includes a sliding ring and several fixing assemblies arranged in a ring array. Each fixing assembly includes a cavity, a pressing block, a clamping rod, a spring, and the pressing rod. The cavity is formed within the wall of the rotating tube. The pressing block is slidably connected within the cavity. One end of the clamping rod is fixedly connected to the end of the pressing block near the rotating shaft. The other end of the clamping rod extends out of the cavity and into a gap via a slidable connection, and is fixedly fitted with a clamping plate for clamping the rotating shaft. The spring is sleeved on the outside of the clamping rod and is fixedly connected... The pressing rod is attached to the wall of the cavity between one end of the pressing block near the rotating shaft and the cavity wall. One end of the pressing rod is fixedly connected to the end of the pressing block opposite to the rotating shaft. The other end of the pressing rod extends out of the cavity in a sliding connection manner. The sliding ring is slidably sleeved on the outside of the rotating tube. Several sliding grooves are opened on the inner side wall of the sliding ring. Several sliding grooves correspond to several pressing rods respectively. The bottom of the groove is set as an inclined surface. The end of the pressing rod that extends out of the cavity is inserted into the groove in a mating connection manner and fits against the bottom wall of the groove, and can slide along the groove.

[0017] By adopting the above technical solution, when one end of the pressing rod is attached to the bottom wall of the chute away from the rotating shaft, the spring is in its original state, and the clamping plate is separated from the rotating shaft. When one end of the pressing rod is attached to the bottom wall of the chute near the rotating shaft, the spring is in a compressed state, and the clamping plate is tightly attached to the rotating shaft. Therefore, the fixing and loosening of the rotating tube and the rotating shaft can be achieved simply by sliding the sliding ring along the axial direction of the rotating tube.

[0018] A further feature of this invention is that one end of the pressing rod that is attached to the bottom wall of the sliding groove is designed to be arc-shaped.

[0019] By adopting the above technical solution, the pressing rod can move more smoothly along the bottom wall of the groove, thereby making the axial movement of the sliding ring smoother.

[0020] A further feature of this invention is that a plurality of strip-shaped limiting grooves are provided on the inner side wall of the sliding ring, and a limiting block is fixed on the outer side wall of the rotating tube for inserting into the strip-shaped limiting grooves and sliding along the strip-shaped limiting grooves.

[0021] By adopting the above technical solution, when the sliding ring moves axially along the rotating tube, the limiting block slides along the strip-shaped limiting groove. This ensures that the sliding ring can only move axially relative to the rotating tube.

[0022] Further features of this invention: Two through slots are provided on the top plate, and a movable structure is provided at the top of the top plate. The movable structure includes a cover, a positive and negative threaded rod, a guide rod, a second motor, and two nut seats. The cover is fixed to the top of the top plate. The positive and negative threaded rod is rotatably connected to the cover body through bearings. The guide rod is fixed inside the cover body. The two nut seats are respectively threaded and sleeved on the outside of the positive threaded part and the negative threaded part of the positive and negative threaded rod, and are slidably sleeved on the outside of the guide rod. A movable rod is fixed at the bottom of each of the two nut seats. The two movable rods correspond to the two through slots respectively. The movable rods pass through the through slots and slide along the through slots, and a movable ring is fixed at its bottom. The sliding ring is rotatably connected to the movable ring through bearings.

[0023] By adopting the above technical solution, when it is necessary to move the two sliding rings, the second motor is started. The second motor drives the forward and reverse threaded rods to rotate, which in turn drives the two nut seats to move in opposite directions along the guide rod. The nut seats drive the moving rod to slide along the through groove. The moving rod drives the moving ring to move. The moving ring drives the sliding ring to move. When the rotating tube rotates, the rotating tube can drive the sliding ring to rotate within the moving ring.

[0024] Further features of this invention: The fabric ironing assembly includes a rubber roller, a heating roller, and two opposing mounting brackets. The two mounting brackets are fixedly connected to both sides of the bonding machine frame. The rubber roller is rotatably connected between the two mounting brackets. Each mounting bracket has an extension rod fixedly attached to it. A connecting rod is fixedly connected between the two extension rods. The connecting rod has an inner cavity. A rotating rod is rotatably connected to the inner cavity via a bearing. Two drive gears are fixedly sleeved on the outside of the rotating rod. A third motor for driving the rotating rod to rotate is installed on the outside of the connecting rod. Each of the two extension rods has a strip groove on one opposite side. A lead screw is rotatably connected to each of the two strip grooves via a bearing. A slider is sleeved on the outside of each of the two lead screws via a threaded connection. One end of each lead screw passes into the inner cavity and is fixedly attached to a driven gear that meshes with the drive gear. The heating roller is rotatably connected between the two sliders.

[0025] By adopting the above technical solution, the third motor is started, which drives the rotating rod to rotate. The rotating rod drives the two driving gears on it to rotate simultaneously. The two driving gears drive the two driven gears to rotate. The two driven gears drive the two lead screws to rotate. The two lead screws drive the two sliders to slide in the slots of the two extension rods. The two sliders drive the heating roller to move, adjusting the distance between the heating roller and the rubber roller, so that the heating roller is always in contact with the surface of the mesh, which to a certain extent increases the pressure on the mesh, smooths out the wrinkles on the surface of the mesh, and further improves the bonding quality of the mesh.

The speed adjustment mechanism in this invention will not cause tooth breakage during the speed adjustment process, and will not accelerate the wear of the first small toothed disc, the first large toothed disc, the second small toothed disc, and the second large toothed disc, thus achieving a lossless speed adjustment effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] A laminating machine for producing laminated mesh fabric, such as Figures 1-4 As shown, the machine includes a laminating frame 1.

[0036] The mesh fabric ironing assembly in this embodiment can refer to the "mesh fabric ironing assembly" in Chinese Patent No. CN221392335U, a mesh fabric bonding and pressing machine, which will not be described in detail here. It may also include a rubber roller 3, a heating roller 4, and two opposing mounting brackets 5. The two mounting brackets 5 are respectively fixedly connected to the left and right sides of the bonding machine frame 1 by bolts. The rubber roller 3 is rotatably connected between the two mounting brackets 5. Each mounting bracket 5 has an integrally formed extension rod 6 extending laterally. A connecting rod 7 extending laterally is fixedly connected between the two extension rods 6 by bolts. The connecting rod 7 has an inner cavity 8 extending in the same direction. A rotating rod 9 extending laterally is rotatably connected to the inner cavity 8 by bearings. Two drive gears 10 are fixedly sleeved on the outside of the rotating rod 9 by set screws.

One end of each lead screw 13 penetrates the inner cavity 8 and is fixed with a driven gear 15 meshing with the driving gear 10 by a set screw. A heating roller 4 is rotatably connected between the two sliders 14. The heating roller 4 utilizes the eddy current effect and hysteresis effect of electromagnetic induction to heat itself, raising the temperature of the working area of ​​the roller in a uniform manner. The third motor 11 is started, driving the rotating rod 9 to rotate. The rotating rod 9 drives the two driving gears 10 to rotate simultaneously. The two driving gears 10 drive the two driven gears 15 to rotate. The two driven gears 15 drive the two lead screws 13 to rotate. The two lead screws 13 drive the two sliders 14 to slide within the slots 12 of the two extension rods 6. Two sliding rollers drive the heating roller 4 to move, adjusting the distance between the heating roller 4 and the rubber roller 3 so that the heating roller 4 is always in contact with the surface of the mesh, which increases the pressure on the mesh to a certain extent, smooths out the wrinkles on the surface of the mesh, and further improves the bonding quality of the mesh.

[0037] The mesh fabric feeding assembly includes a fixed frame 16, a winding roller 17, an adjustable speed mechanism, and two opposing limiting collars 18. The fixed frame 16, winding roller 17, and limiting collars 18 can all be referenced in the "fixed frame 16, winding roller 17, and limiting collars 18" of Chinese Patent No. CN221392335U, a mesh fabric laminating and pressing machine, and will not be described in detail here.

[0038] The adjustable speed mechanism includes a top plate 19, a bottom plate 20, a first large gear 21, a first small gear 22, a second large gear 23, a second small gear 24, a first motor 25, a drive shaft 26, and two rotating tubes 29.

[0039] The base plate 20 is bolted to the bottom end of the right outer side wall of the mounting bracket 16. The first motor 25 is bolted to the top of the base plate 20. One end of the drive shaft 26 is fixedly connected to the output shaft of the first motor 25 via a coupling. The other end of the drive shaft 26 extends horizontally to the left and is rotatably connected to the mounting bracket 16 via a bearing.

[0040] The top plate 19 is bolted to the top of the right outer wall of the fixing frame 16. Three vertical plates 27, spaced apart from left to right, are bolted to the bottom of the top plate 19. One end of the winding roller 17 has an integrally formed rotating shaft 28, concentrically and coaxially arranged therewith. The other end of the rotating shaft 28 passes sequentially through the fixing frame 16 and the three vertical plates 27, and is rotatably connected to the fixing frame 16 and the three vertical plates 27 via bearings.

[0041] Two rotating tubes 29 are rotatably connected between two adjacent vertical plates 27 via bearings, and both are sleeved on the outside of the rotating shaft 28. The rotating tubes 29 and the rotating shaft 28 are arranged concentrically and coaxially, and a gap is maintained between their inner sidewalls and the outer sidewalls of the rotating shaft 28. The rotating tubes 29 are provided with fixing components for fixing the rotating tubes 29 to the rotating shaft 28.

[0042] It is worth noting that, for ease of description, in the following description of this embodiment, the two rotating tubes 29 will be referred to as the first rotating tube 29 and the second rotating tube 29 from left to right.

[0043] The first large gear 21 and the first small gear 22 are both fixedly sleeved on the outside of the drive shaft 26 by set screws. The second large gear 23 and the second small gear 24 are respectively fixedly sleeved on the outside of the first rotating tube 29 and the second rotating tube 29 by set screws. The first large gear 21 meshes with the second small gear 24, and the first small gear 22 meshes with the second large gear 23.

[0044] The fixing components include a sliding ring 31 and four fixing assemblies arranged in a ring array. Each fixing assembly includes a cavity 32, a pressing block 33, a clamping rod 34, a spring 35, and a pressing rod 36. The cavity 32 is formed within the wall of the rotating tube 29. The pressing block 33 is slidably connected within the cavity 32 and can move radially along the cavity 32 relative to the rotating shaft 28. One end of the clamping rod 34 is bolted to the end of the pressing block 33 near the rotating shaft 28. The other end of the clamping rod 34 extends out of the cavity 32 in a slidable connection and enters the gap, and is bolted to a clamping plate 37 for clamping the rotating shaft 28. The end of the clamping plate 37 near the rotating shaft 28 is configured with an arc shape matching the outer wall of the rotating shaft 28. The spring 35 is sleeved on the outside of the clamping rod 34 and fixedly connected between the end of the pressing block 33 near the rotating shaft 28 and the cavity wall of the cavity 32. One end of the pressing rod 36 is fixedly connected to the end of the pressing block 33 facing away from the rotating shaft 28 by bolts. The other end of the pressing rod 36 slides out of the cavity 32. The sliding ring 31 is slidably sleeved on the outside of the rotating tube 29. Four horizontally extending grooves 38 are provided on the inner sidewall of the sliding ring 31. The four grooves 38 correspond to a number of pressing rods 36. The bottom of the groove 38 is set as an inclined surface, which is a plane with unequal distances from the rotating shaft 28 at both ends. In this embodiment, the left end of the bottom of the groove 38 is closer to the rotating shaft 28, and the right end of the bottom of the groove 38 is further away from the rotating shaft 28. The end of the pressing rod 36 that extends out of the cavity 32 is inserted into the groove 38 in a mating connection and fits against the bottom wall of the groove 38. The pressing rod 36 can slide along the groove 38.

[0045] It is worth noting that, for ease of description, in the following description of this embodiment, the two sliding rings 31 will be referred to as the first sliding ring 31 and the second sliding ring 31 from left to right. When the pressing rod 36 in the first rotating tube 29 corresponds to the leftmost end of the groove 38 of the first sliding ring 31 (that is, when the pressing rod 36 is attached to the bottom wall of the groove 38 near the rotating shaft 28), the pressing rod 36 in the second rotating tube 29 corresponds to the rightmost end of the groove 38 of the second sliding ring 31 (that is, when the pressing plate is attached to the bottom wall of the groove 38 away from the rotating shaft 28). Similarly, when the pressing rod 36 in the first rotating tube 29 corresponds to the rightmost end of the groove 38 of the first sliding ring 31, the pressing rod 36 in the second rotating tube 29 corresponds to the leftmost end of the groove 38 of the second sliding ring 31.

[0046] Two through slots 39 are formed on the top plate 19. A movable structure is provided at the top of the top plate 19. The movable structure includes a cover 40, a threaded rod 41, a guide rod 42, a second motor 43, and two nut seats 44. The cover 40 is fixed to the top of the top plate 19 by bolts. The threaded rod 41 is rotatably connected to the inside of the cover 40 by bearings. The guide rod 42 is fixed inside the cover 40. Both the threaded rod 41 and the guide rod 42 extend laterally to the left and right. The two nut seats 44 are respectively threaded onto the outside of the threaded rod 41 (forward and reverse threads) and are slidably fitted onto the outside of the guide rod 42. The bottom of each of the two nut seats 44 is fixed with a movable rod 45 by bolts. The two movable rods 45 correspond to the two through slots 39 respectively. The movable rods 45 pass through the through slots 39 and slide along the through slots 39, and their bottoms are fixed with movable rings 30 by bolts. The sliding ring 31 is rotatably connected to the moving ring 30 via a bearing.

[0047] Additionally, one end of the pressing rod 36 that adheres to the bottom wall of the groove 38 is curved. This allows the pressing rod 36 to move more smoothly along the bottom wall of the groove 38, thereby making the axial movement of the sliding ring 31 smoother.

[0048] The inner wall of the sliding ring 31 is also provided with several strip-shaped limiting grooves (not shown in the figure), and the outer wall of the rotating tube 29 is fixed with a limiting block (not shown in the figure) for inserting into the strip-shaped limiting grooves and sliding along the strip-shaped limiting grooves. When the sliding ring 31 moves axially along the rotating tube 29, the limiting block slides along the strip-shaped limiting grooves. This ensures that the sliding ring 31 can only move axially relative to the rotating tube 29.

[0049] Working principle:

[0050] After the first motor 25 is started and drives the drive shaft 26 to rotate, the drive shaft 26 drives the first large gear 21 and the first small gear 22 to rotate. The first large gear 21 drives the second small gear 24 to rotate, and the first small gear 22 drives the second large gear 23 to rotate. The second small gear 24 and the second large gear 23 respectively drive the second rotating tube 29 and the first rotating tube 29 to rotate. When the second rotating tube 29 and the first rotating tube 29 rotate, they can drive the sliding ring 31 on them to rotate within the corresponding moving ring 30.

[0051] When the first rotating tube 29 is fixed to the rotating shaft 28, and the second rotating tube 29 is not fixed to the rotating shaft 28, the first rotating tube 29 drives the rotating shaft 28 to rotate. The second rotating tube 29 only rotates between the two vertical plates 27 and has no effect on the rotating shaft 28. At this time, the first small gear 22 drives the second large gear 23, the second large gear 23 drives the first rotating tube 29, and the first rotating tube 29 drives the rotating shaft 28. The rotational speed of the rotating shaft 28 is relatively slow, i.e., this is the low-speed gear. Similarly, when the second rotating tube 29 is fixed to the rotating shaft 28, and the first rotating tube 29 is not fixed to the rotating shaft 28, this is the high-speed gear.

[0052] When it is necessary to shift from a low speed to a high speed, the second motor 43 is activated. The second motor 43 drives the forward and reverse threaded rods 41 to rotate clockwise. The forward and reverse threaded rods 41 drive the two nut seats 44 to move in the opposite direction along the guide rod 42. The two nut seats 44 drive the two moving rods 45 to slide in the opposite direction along the through groove 39. The two moving rods 45 drive the two moving rings 30 to move in the opposite direction. The two moving rings 30 drive the first sliding ring 31 and the second sliding ring 31 to move in the opposite direction. That is, the first sliding ring 31 moves to the left, and the second sliding ring 31 moves to the right. When the first sliding ring 31 slides to the left, under the action of the rebound force of the spring 35, the pressing rod 36, the pressing block 33, the clamping rod, and the clamping plate all move radially away from the rotating shaft 28. The clamping plate separates from the rotating shaft 28, and the first rotating tube 29 is no longer fixed to the rotating shaft 28. When the second sliding ring 31 moves to the right, it presses the pressing rod 36 against the bottom wall of the groove 38, causing the pressing rod 36 to move radially toward the rotating shaft 28. The pressing rod 36 drives the pressing block 33 to move radially toward the rotating shaft 28. The pressing block 33 drives the clamping rod to move radially toward the rotating shaft 28. The clamping rod drives the clamping plate to move radially toward the rotating shaft 28, thereby clamping the rotating shaft 28 through the clamping plate, and the second rotating tube 29 can then be fixed on the rotating shaft 28.

[0053] Similarly, when it is necessary to switch from a high speed to a low speed, the second motor 43 is started, causing its output shaft to rotate in the opposite direction. The forward and reverse rotation of the output shaft of the second motor 43 can be achieved by a reversing switch, which is prior art well known to those skilled in the art, and will not be described in detail here.

[0054] In this embodiment, when switching between low speed and high speed, the first motor 25 should be turned off first.

[0055] The speed regulation mechanism of this invention will not experience tooth breakage during the speed regulation process, and will not accelerate the wear of the first small gear plate, the first large gear plate, the second small gear plate, and the second large gear plate, thus achieving a lossless speed regulation effect.
