Description

Technical Field

[0001] This utility model relates to friction lines, or more precisely, a friction line power module. Background Technology

[0002] Friction lines are primarily used for product transfer on production lines. Existing friction lines typically include a frame, a drive motor mounted on the frame, a shaft connected to and rotating under the drive motor's power, a friction line power module mounted on the shaft and rotating with it, a driven gear connected to and rotating under the power module's power, and friction wheels connected to and rotating with the driven gear. Multiple friction wheels are arranged in a row. In actual use, a carrier containing products is placed on the friction wheels. The drive motor drives the shaft to rotate, thereby rotating the friction wheels and moving the carrier, thus transferring the products on the production line. However, existing friction line power modules have a complex structure, and each component is individually mounted on the shaft, making installation inconvenient. Utility Model Content

[0003] To address the technical problems of complex structure and inconvenient installation of existing friction line power modules, this utility model provides a friction line power module and a friction line.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a friction line power module, comprising:

[0005] A fixed sleeve includes a sleeve shaft and a fixed boss that is disposed on the outer surface of the sleeve shaft and protrudes outward. The sleeve shaft is provided with a rotating shaft hole centered on the central axis of the sleeve shaft in the axial direction. One end of the sleeve shaft is provided with a sleeve shaft threaded portion, and the outer surface of the sleeve shaft threaded portion is also provided with an adjusting thread.

[0008] A spring, which is fitted onto the sleeve shaft;

[0009] A pressure regulating part is fitted onto and threadedly connected to the threaded part of the sleeve shaft. The fixed boss, drive gear, spring, and pressure regulating part are arranged in sequence. The pressure regulating part compresses the spring between the drive body of the drive gear and the pressure regulating part, and uses the compression force of the spring to press the drive body against one side of the fixed boss. Rotating the pressure regulating part adjusts its position on the threaded part of the sleeve shaft and adjusts the compression force of the spring. When the external force acting on the drive gear is balanced with the frictional force on the drive gear, the drive gear rotates together with the sleeve shaft. When the drive gear stops rotating and the external force acting on the sleeve shaft overcomes the frictional force on the drive gear, the sleeve shaft rotates relative to the drive gear.

[0010] The outer surface of the sleeve shaft is also provided with a sleeve shaft positioning part arranged along the axial direction; the sleeve shaft positioning part and the adjusting thread are located on the same side of the fixed boss;

[0011] The friction line power module also includes:

[0012] A first friction pad is fitted onto the sleeve shaft and is axially movable relative to the sleeve shaft. The first friction pad is pressed by the spring between the fixed boss and the drive body of the drive gear. The first friction pad is provided with a first pad positioning part corresponding to the sleeve shaft positioning part. The first pad positioning part cooperates with the sleeve shaft positioning part to prevent the first friction pad from rotating relative to the sleeve shaft.

[0013] One end of the drive body is provided with a recessed pad groove, and the depth of the pad groove is less than the thickness of the first friction pad. One end of the first friction pad is inserted into the pad groove, and the other end is in close contact with one side of the fixed boss.

[0014] The drive body is provided with drive sleeve holes that penetrate both ends of the drive body. The drive sleeve holes are fitted onto the sleeve shaft. The bottom of the gasket groove is provided with recessed grooves that are spaced apart and penetrate into the drive sleeve holes.

[0015] The sleeve positioning part is a flat part formed by cutting the outer surface of the sleeve shaft along the axial direction; the first friction pad is provided with a pad hole at the center, and the first friction pad is sleeved on the sleeve shaft through the pad hole; the first pad positioning part is a pad boss that extends inward from the pad hole and has a flat inner surface; when the first friction pad is sleeved on the sleeve shaft, the inner surface of the pad boss is directly opposite the flat part.

[0016] The friction line power module also includes:

[0017] The second friction pad is sleeved on the sleeve shaft and can move axially relative to the sleeve shaft. The second friction pad is pressed between the drive body of the drive gear and the spring by the spring. The second friction pad is provided with a second pad positioning part corresponding to the sleeve shaft positioning part. The second pad positioning part cooperates with the sleeve shaft positioning part to prevent the second friction pad from rotating relative to the sleeve shaft. The structure of the second friction pad is the same as that of the first friction pad.

[0018] The friction line power module also includes:

[0019] The third friction pad is fitted onto the threaded portion of the sleeve shaft and is axially movable relative to the sleeve shaft. The third friction pad is pressed between the pressure adjusting portion and the spring by the spring. The sleeve shaft positioning portion passes through the threaded portion of the sleeve shaft. The third friction pad is provided with a third pad positioning portion corresponding to the sleeve shaft positioning portion. The third pad positioning portion cooperates with the sleeve shaft positioning portion to prevent the third friction pad from rotating relative to the sleeve shaft. The structure of the third friction pad is the same as that of the first friction pad.

[0020] The other end of the sleeve shaft is provided with a fixing part, and the fixing boss is located between the fixing part and the threaded part of the sleeve shaft. An elastic groove penetrating the shaft hole is opened on the outer surface of the fixing part. The fixing member includes a retaining ring sleeved on the fixing part and fasteners that clamp the two ends of the retaining ring.

[0021] The pressure regulating unit includes:

[0022] Adjust the main body;

[0023] A threaded hole is provided on the adjusting body; the inner surface of the threaded hole is provided with an internal thread, and the pressure adjusting part is sleeved on the sleeve threaded part through the threaded hole and the internal thread is threadedly connected to the adjusting thread.

[0024] The spring arm groove is located at one end of the adjusting body and is formed by the outward indentation of the inner side of the threaded hole;

[0025] An elastic arm is disposed in the elastic arm groove and extends from the side of the elastic arm groove along the axial direction of the adjusting body;

[0026] The positioning arm is formed by extending the end of the elastic arm away from the bottom surface of the elastic arm groove along the radial direction of the adjusting body towards the center; the end of the positioning arm is provided with a positioning protrusion.

[0027] The fixing sleeve also includes an inwardly recessed positioning groove that is arranged along the axial direction of the sleeve shaft and is located on the threaded portion of the sleeve shaft; the positioning protrusion can be inserted into the positioning groove to prevent the pressure adjustment part from rotating relative to the threaded portion of the sleeve shaft without external force, and when the adjustment body is rotated by external force, the positioning protrusion can be rotated out of the positioning groove and rotate together with the adjustment body.

[0028] This utility model also provides a friction line, comprising:

[0029] frame;

[0030] The drive motor is mounted on the frame;

[0031] A rotating shaft, which is connected to the drive motor and rotates under the drive of the drive motor;

[0032] A driven gear is mounted on the frame and is rotatable relative to the frame;

[0033] A friction wheel, which is connected to the driven gear and rotates with the driven gear;

[0034] The friction line also includes the aforementioned friction line power module. The fixed sleeve is fitted onto the rotating shaft through the rotating shaft hole. The fixing member fixes the fixed sleeve onto the rotating shaft. The fixed sleeve rotates together with the rotating shaft. The driven gear meshes with the driving gear.

[0035] The drive motor drives the rotating shaft to rotate. The external force acting on the drive gear is balanced with the frictional force on the drive gear. The drive gear rotates synchronously with the rotating shaft, driving the friction wheel to rotate. When the friction wheel is blocked by an external force and stops rotating, the drive gear stops rotating. At this time, the external force acting on the sleeve shaft overcomes the frictional force on the drive gear, and the sleeve shaft rotates with the rotating shaft. The sleeve shaft and the rotating shaft rotate relative to the drive gear.

[0036] The friction line power module includes multiple units, which are evenly spaced along the rotating shaft; the driven gear and friction wheel each include multiple units, which are arranged in a one-to-one correspondence with the friction line power module.

[0037] This utility model comprises a fixed sleeve, a fixing member, a drive gear, a spring, and a pressure adjusting part. The fixed sleeve includes a sleeve shaft and a fixing boss protruding outward from the outer surface of the sleeve shaft; one end of the sleeve shaft has a sleeve shaft thread; the fixing member is connected to the fixed sleeve and fixes the fixed sleeve to a rotating shaft; the drive gear includes a drive body and drive teeth on the outer surface of the drive body, the drive body being sleeved on the sleeve shaft; the spring is sleeved on the sleeve shaft; the pressure adjusting part is sleeved on the sleeve shaft thread and threadedly connected to the sleeve shaft thread; the fixing boss, drive gear, spring, and pressure adjusting part are arranged in sequence. In this configuration, the pressure regulating unit compresses the spring between the drive body of the drive gear and the pressure regulating unit itself. The spring's compression force presses the drive body against one side of the fixed boss. Rotating the pressure regulating unit adjusts its position on the threaded portion of the sleeve shaft, thus adjusting the spring's compression force. When the external force acting on the drive gear balances the frictional force acting on the drive gear, the drive gear rotates together with the sleeve shaft. When the drive gear stops rotating and the external force acting on the sleeve shaft overcomes the frictional force acting on the drive gear, the sleeve shaft rotates relative to the drive gear. Therefore, in use, it is only necessary to first assemble the friction line power module, then fit the drive gear and spring onto the sleeve shaft, and fit the pressure regulating unit onto the threaded portion of the sleeve shaft. This completes the assembly of the friction line power module. Finally, the fixed sleeve is fitted onto the rotating shaft, and the fixed sleeve is fixed to the rotating shaft using fasteners. This completes the installation of the friction line power module onto the rotating shaft. The structure is very simple, and installation is very convenient. Furthermore, the frictional force acting on the drive gear can be adjusted by regulating the spring's compression force through the pressure regulating unit. Furthermore, when the drive gear stops rotating, the external force acting on the sleeve shaft by the rotating shaft overcomes the frictional force on the drive gear, and the sleeve shaft rotates relative to the drive gear. Therefore, when it is necessary to pause the product at the current position, it is only necessary to block the rotation of the friction wheel to make the rotating shaft rotate while the drive gear remains stationary, without hindering the operation of other friction line power modules.

[0046] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0047] Please see also Figures 1 to 7 This utility model friction line includes a frame 1, a drive motor (not shown in the figure), a rotating shaft 2, a driven gear 3, a friction wheel 4, and a friction line power module 5. Wherein;

[0048] The frame 1 primarily serves a supporting function. The frame 1 typically includes two opposing support rods 11.

[0049] The drive motor is mounted on the frame; the drive motor is mainly used to provide power and drive the shaft to rotate.

[0050] The rotating shaft 2 is connected to the drive motor and rotates under the drive of the drive motor. The rotating shaft 2 is supported on the support rod 11 and is arranged parallel to the support rod. In this specific embodiment, there are two rotating shafts 2, which are respectively located on the outside of the two support rods.

[0051] Driven gear 3 is mounted on the frame and can rotate relative to the frame. Driven gear 3 is mainly used to cooperate with friction line power module 5 to realize the transmission of force from friction line power module to friction wheel, or from friction wheel to friction line power module.

[0052] Friction wheel 4 is connected to the driven gear and rotates with the driven gear. In this specific embodiment, the driven gear is located on the outside of the support rod, and the friction wheel is located on the inside of the support rod. There are multiple driven gears and friction wheels, which are evenly distributed parallel to each other along the axial direction of the rotating shaft and are symmetrically arranged in two rows on the two support rods, so that the force and driving force on the carrier carrying the product are more uniform.

[0053] The friction line power module 5 includes a fixed sleeve 51, a fixing member 52, a drive gear 53, a spring 54, and a pressure adjustment part 55.

[0054] in:

[0055] The fixed sleeve 51 includes a sleeve shaft 511 and a fixed boss 512 protruding outward from the outer surface of the sleeve shaft. The sleeve shaft 511 has an axially arranged pivot hole 5111 centered on its central axis; one end of the sleeve shaft 511 has a sleeve shaft threaded portion 5112, and the outer surface of the sleeve shaft threaded portion 5112 also has an adjusting thread 5113. The sleeve shaft is mainly used to assemble the drive gear, spring, and pressure adjusting part into a single unit, avoiding the need for subsequent individual installation on the rotating shaft. The fixed boss mainly acts as a blocking element, clamping the spring and drive gear together with the pressure adjusting part, so that the spring's compression force acts on the drive gear, thereby generating friction on the drive gear when the rotating shaft rotates. By adjusting the position of the pressure adjusting part, the compression length of the spring can be adjusted, thereby adjusting the pressure acting on the drive gear and the maximum friction force that can be generated on the drive gear. Simultaneously, the sleeve shaft also facilitates the assembly of the drive gear and spring; simply fitting the drive gear and spring onto the sleeve shaft is sufficient.

[0056] The fastener 52 is connected to the fastener sleeve and fixes the fastener sleeve to the rotating shaft. After the fastener sleeve is fitted onto the rotating shaft, the fastener sleeve is fixed to the rotating shaft.

[0057] In this specific embodiment, a fixing part 513 is provided at the other end of the sleeve shaft 511. The fixing boss is located between the fixing part and the threaded part of the sleeve shaft. An elastic groove 5131 penetrating the shaft hole is formed on the outer surface of the fixing part 513. The fixing member 52 includes a retaining ring 521 sleeved on the fixing part and fasteners (not shown in the figure) that clamp the two ends of the retaining ring. The elastic groove is mainly used to allow the fixing part to undergo elastic deformation, thereby fixing the fixing part to the shaft.

[0058] The retaining ring 521 has screw holes 5211 at both ends. Fasteners, such as screws or bolts, pass through the screw holes, pressing the retaining ring firmly onto the fixing part. Simultaneously, the pressure generated by the retaining ring acts on the fixing part, securing it to the rotating shaft. In this specific embodiment, multiple elastic grooves are evenly distributed around the fixing part. An elastic sheet 5132 is formed between two adjacent elastic grooves. The retaining ring is fitted onto the elastic sheet. During the fastening process, the pressure generated by the retaining ring causes the elastic sheet 5132 to undergo elastic deformation, thereby fixing the fixing part to the rotating shaft.

[0059] Of course, the fixing sleeve can also be directly fixed to the rotating shaft using screws or pins. However, since the clamping ring method is more convenient, it is preferred.

[0060] The drive gear 53 includes a drive body 531 and drive teeth 532 disposed on the outer surface of the drive body, the drive body being sleeved on the shaft. The drive teeth and driven gear are meshing bevel teeth, thereby enabling steering of motion. The drive gear and driven gear can be made of metal or plastic.

[0061] Spring 54 is sleeved on the shaft. The spring is mainly used to generate compressive force, thereby pressing the drive body tightly. At the same time, the elastic force generated by the spring also acts on the pressure regulating part, which can prevent the pressure regulating part from accidentally loosening.

[0062] The pressure adjusting part 55 is sleeved on the threaded part of the sleeve shaft and threadedly connected to the threaded part of the sleeve shaft; the fixed boss 512, the drive gear 52, the spring 54 and the pressure adjusting part 55 are arranged in sequence. The pressure adjusting part compresses the spring between the drive body of the drive gear and the pressure adjusting part, and presses the drive body against one side of the fixed boss by means of the compression force of the spring. Rotating the pressure adjusting part adjusts the position of the pressure adjusting part on the threaded part of the sleeve shaft and adjusts the compression force of the spring; when the external force acting on the drive gear is balanced with the friction force on the drive gear, the drive gear rotates together with the sleeve shaft; when the drive gear stops rotating and the external force acting on the sleeve shaft overcomes the friction force on the drive gear, the sleeve shaft rotates relative to the drive gear. By rotating the pressure adjustment unit, the pressure adjustment unit moves axially along the sleeve shaft thread, thereby adjusting the spring compression length to adjust the spring compression force, changing the axial pressure on the drive body, and thus changing the maximum friction force on the drive body, so as to adjust the driving force of the friction wheel on the carrier carrying the product.

[0063] The fixed sleeve 51 is fitted onto the rotating shaft 2 through the rotating shaft hole 5111, and the fixing member 52 fixes the fixed sleeve 51 onto the rotating shaft 2. The fixed sleeve rotates together with the rotating shaft. The driven gear 3 meshes with the driving gear 53.

[0064] The drive motor drives the rotating shaft to rotate. The external force acting on the drive gear is balanced by the frictional force on the drive gear. The drive gear rotates synchronously with the rotating shaft, driving the friction wheel to rotate. When the friction wheel stops rotating due to external force, the drive gear stops rotating. At this time, when the external force acting on the sleeve shaft overcomes the frictional force on the drive gear, the sleeve shaft rotates with the rotating shaft, and the sleeve shaft and the rotating shaft rotate relative to the drive gear. The friction wheel stopping rotating due to external force can be achieved by blocking the movement of the carrier carrying the product. When it is necessary to stop the carrier in its current position, a stop lever can be driven by a cylinder to stop the carrier, thus stopping the carrier's movement and causing the friction wheel to stop rotating. At this time, the force exerted by the friction wheel on the drive gear through the driven gear is greater than the frictional force on the drive gear, causing the drive gear to stop rotating. The external force acting on the sleeve shaft overcomes the frictional force on the drive gear, and the sleeve shaft continues to rotate with the rotating shaft, thus rotating relative to the drive gear. This does not obstruct the rotation of the drive gears of other friction line power modules, and the unobstructed carrier will continue to move.

[0065] The friction line power module includes multiple units, which are evenly spaced along the rotating shaft; the driven gear and friction wheel each include multiple units, which are arranged in a one-to-one correspondence with the friction line power module.

[0066] In use, simply assemble the friction line power module first. Place the drive gear and spring onto the sleeve shaft, and then fit the pressure adjustment part onto the threaded part of the sleeve shaft. This completes the assembly. Next, place the fixing sleeve onto the rotating shaft and secure it using fasteners. This completes the installation of the friction line power module onto the rotating shaft. The structure is very simple, and installation is very convenient. Furthermore, the friction force on the drive gear can be adjusted by regulating the spring's compression force through the pressure adjustment part. In addition, since the external force acting on the sleeve shaft overcomes the friction force on the drive gear, the sleeve shaft rotates relative to the drive gear. Therefore, when it is necessary to pause the product in its current position, simply blocking the rotation of the friction wheel will allow the rotating shaft to rotate while the drive gear remains stationary, without interfering with the operation of other friction line power modules.

[0067] In this specific embodiment, the outer surface of the sleeve shaft 511 is also provided with a sleeve shaft positioning part 5114 arranged along the axial direction; the sleeve shaft positioning part 5114 and the adjusting thread 5113 are located on the same side of the fixed boss 512.

[0068] The friction line power module 5 also includes a first friction pad 56. The first friction pad 56 is sleeved on the sleeve shaft and can move axially relative to the sleeve shaft. The first friction pad is pressed between the fixed boss and the drive body of the drive gear by the spring. The first friction pad 56 is provided with a first pad positioning part 561 corresponding to the sleeve shaft positioning part. The first pad positioning part cooperates with the sleeve shaft positioning part to prevent the first friction pad from rotating relative to the sleeve shaft.

[0069] By using the first friction pad, direct contact between the drive gear body and the fixed boss can be avoided. Furthermore, because the first friction pad engages with the sleeve shaft positioning part through the first pad positioning part, the first friction pad will not rotate relative to the sleeve shaft. Therefore, when the drive gear and the shaft rotate relative to each other, the fixed boss will not be worn, thus preventing damage to the sleeve shaft. When the first friction pad or the drive gear needs to be replaced due to wear, only the first friction pad or the drive gear needs to be replaced, significantly reducing usage and maintenance costs.

[0070] In this specific embodiment, one end of the drive body 531 is provided with a recessed pad groove 533, and the depth of the pad groove is less than the thickness of the first friction pad. One end of the first friction pad is inserted into the pad groove, and the other end is in close contact with one side of the fixing boss. By providing a pad groove and making the depth of the pad groove less than the thickness of the first friction pad, the structure of the entire friction line power module can be made more compact, smaller in size, and more aesthetically pleasing.

[0071] In this specific embodiment, the drive body 531 is provided with drive sleeve holes 5311 that penetrate both ends of the drive body, the drive sleeve holes are fitted onto the sleeve shaft, and the bottom of the gasket groove 533 is provided with recessed grooves 5331 that are spaced apart and penetrate into the drive sleeve holes.

[0072] The grooves effectively conduct and dissipate the heat generated by the first friction pad and the drive body, which is beneficial for heat dissipation and avoids heat accumulation that could damage the first friction pad and the drive gear. At the same time, the grooves can also increase the maximum friction between the first friction pad and the drive body, thereby improving the driving force.

[0073] In this specific embodiment, the sleeve positioning part 5114 is a flat part formed by cutting the outer surface of the sleeve shaft along the axial direction; the first friction pad 56 has a pad hole 562 at its center, and the first friction pad is sleeved on the sleeve shaft through the pad hole. The first pad positioning part 561 is a pad boss extending inward from the pad hole and having a flat inner surface. When the first friction pad is sleeved on the sleeve shaft, the inner surface of the pad boss is directly opposite the flat part, thereby preventing the first friction pad from rotating relative to the sleeve shaft. Of course, the sleeve positioning part can also be set as a recessed positioning groove opened on the sleeve shaft, and the first pad positioning part can be a protruding positioning piece, which is inserted into the positioning groove to prevent the first friction pad from rotating relative to the sleeve shaft.

[0074] In this specific embodiment, the friction line power module further includes a second friction pad 57. The second friction pad 57 is sleeved on the sleeve shaft and can move axially relative to the sleeve shaft. The second friction pad is pressed between the drive body of the drive gear and the spring by the spring. The second friction pad 57 is provided with a second pad positioning part 571 corresponding to the sleeve shaft positioning part. The second pad positioning part cooperates with the sleeve shaft positioning part to prevent the second friction pad from rotating relative to the sleeve shaft. The structure of the second friction pad is the same as that of the first friction pad. By providing a second friction pad, direct contact between the drive body and the spring can be avoided, and wear on the spring can be avoided when the drive gear rotates relative to the sleeve shaft. Therefore, in later maintenance, only the second friction pad needs to be replaced, and the spring does not need to be replaced, which can significantly reduce the use and maintenance costs. At the same time, the structure of the second friction pad is the same as that of the first friction pad, so no distinction is needed during installation, which is convenient for manufacturing and installation.

[0075] In this specific embodiment, the friction line power module further includes a third friction pad 58. The third friction pad 58 is sleeved on the threaded portion of the sleeve shaft and can move axially relative to the sleeve shaft. The third friction pad is pressed between the pressure adjusting part and the spring by the spring. The sleeve shaft positioning part passes through the threaded portion of the sleeve shaft. The third friction pad 58 is provided with a third pad positioning part 581 corresponding to the sleeve shaft positioning part. The third pad positioning part cooperates with the sleeve shaft positioning part to prevent the third friction pad from rotating relative to the sleeve shaft. The structure of the third friction pad is the same as that of the first friction pad. The third friction pad is located between the spring and the pressure adjusting part, which can prevent the spring from directly contacting the pressure adjusting part and facilitate the operation of the pressure adjusting part. The structure of the third friction pad is the same as that of the first friction pad, so there is no need to distinguish them during installation, which is convenient for manufacturing and installation.

[0076] In this specific embodiment, the pressure regulating unit 55 includes an regulating body 551, a threaded hole 552, a spring arm groove 553, an elastic arm 554, and a positioning arm 555. Wherein:

[0077] The adjustment body 551 is mainly used for holding and rotating the pressure adjustment part during adjustment.

[0078] A threaded hole 552 is provided on the adjusting body; the inner surface of the threaded hole 552 is provided with an internal thread 5521, and the pressure adjusting part is sleeved on the sleeve shaft threaded part through the threaded hole and the internal thread is threadedly connected to the adjusting thread.

[0079] The spring arm groove 553 is located at one end of the adjustment body and is formed by the outward indentation of the inner side of the threaded hole.

[0080] The elastic arm 554 is disposed in the elastic arm groove and extends from the side of the elastic arm groove along the axial direction of the adjusting body.

[0081] The positioning arm 555 is formed by extending the end of the elastic arm away from the bottom surface of the elastic arm groove along the radial direction of the adjusting body towards the center; the end of the positioning arm 555 is provided with a positioning protrusion 5551.

[0082] The fixing sleeve 51 further includes an inwardly recessed positioning groove 514 disposed along the axial direction of the sleeve shaft and on the threaded portion of the sleeve shaft; the positioning protrusion can be inserted into the positioning groove to prevent the pressure adjusting part from rotating relative to the threaded portion of the sleeve shaft without external force, and when the adjusting body is rotated by external force, the positioning protrusion can be unscrewed from the positioning groove and rotate together with the adjusting body. In this specific embodiment, both the positioning protrusion and the positioning groove are pointed, and the two inclined surfaces of the pointed corners can be used to facilitate the positioning protrusion from the positioning groove.

[0083] The elastic arm can deform, facilitating the disengagement of the positioning latch from the positioning slot when the adjusting body is rotated. When the positioning latch is engaged in the positioning slot, it prevents the pressure adjusting part from rotating relative to the sleeve shaft. Combined with the threaded connection between the pressure adjusting part and the sleeve shaft, this effectively prevents the pressure adjusting part from loosening. When it is necessary to adjust the spring compression force, the adjusting body is rotated forcefully. Due to the deformation of the elastic arm, the positioning latch disengages from the positioning slot and rotates with the adjusting body, thereby allowing the pressure adjusting part to move relative to the sleeve shaft thread, adjusting the spring compression length.

[0084] This utility model, by setting a fixed sleeve, a fixing component, a drive gear, a spring, a pressure adjusting part, a first friction pad, a second friction pad, and a third friction pad, can be installed by simply placing the first friction pad, the drive gear, the second friction pad, and the spring onto the sleeve shaft of the fixed sleeve in sequence, then threading the pressure adjusting part to the threaded part of the sleeve shaft, and finally placing the retaining ring of the fixing component onto the fixing part of the fixed sleeve. The installation of the friction line power module is then completed. The overall structure is very simple and easy to install.

[0085] When installing on a friction line, simply slip the entire friction line power module onto the rotating shaft, and then use fasteners to secure the fixing sleeve to the shaft. This completes the installation of the friction line power module onto the rotating shaft, making the structure very simple and installation very convenient. Furthermore, the frictional force on the drive gear can be adjusted by regulating the spring's compression force through the pressure adjustment unit. In addition, when an external force acts on the sleeve shaft to overcome the frictional force on the drive gear, the sleeve shaft rotates relative to the drive gear. Therefore, when it is necessary to pause the product in its current position, simply blocking the rotation of the friction wheel will allow the rotating shaft to rotate while the drive gear remains stationary, without interfering with the operation of other friction line power modules.

[0086] This utility model has a simple structure and is easy to install. The pressure on the drive gear can be adjusted by adjusting the compression length of the spring through the pressure adjustment part, thereby adjusting the driving force. After the friction power module is installed on the friction line, the pressure on the drive gear can be easily adjusted according to the actual situation.

[0087] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
