[0027] The fixed sleeve further includes a positioning card slot that is axially arranged along the sleeve shaft and is recessed inwardly on the threaded portion of the sleeve shaft; the positioning card convex can be inserted into the positioning card slot to prevent the pressure adjusting portion from rotating relative to the threaded portion of the sleeve shaft without external force, and when the adjusting body is rotated by an external force, the positioning card convex can be screwed out of the positioning card slot and rotate together with the adjusting body.

[0028] The present invention also provides a friction wire, comprising:

The fixed sleeve rotates together with the rotating shaft; the driven gear meshes with the driving gear;

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

The fixing sleeve includes a sleeve shaft and a fixing boss protruding outwardly on the outer surface of the sleeve shaft; one end of the sleeve shaft is provided with a sleeve shaft thread part; the fixing member is connected to the fixing sleeve and fixes the fixing sleeve on the rotating shaft; the driving gear includes a driving body and driving teeth provided on the outer surface of the driving body, and the driving body is sleeved on the sleeve shaft; the spring is sleeved on the sleeve shaft; the pressure adjusting part is sleeved on the sleeve shaft thread part and is threadedly connected to the sleeve shaft thread part; the fixing boss, the driving gear, the spring and the pressure adjusting part are arranged in sequence, the pressure adjusting part compresses the spring between the driving body of the driving gear and the pressure adjusting part, and presses the driving body against one side of the fixing boss by means of the compression elastic force of the spring; by rotating the pressure adjusting part to adjust the position of the pressure adjusting part on the sleeve shaft thread part, the compression elastic force of the spring is adjusted; when the external force acting on the driving gear is balanced with the frictional force received by the driving gear, the driving gear rotates together with the sleeve shaft; when the driving gear stops rotating and the external force acting on the sleeve shaft overcomes the frictional force received by the driving gear, the sleeve shaft rotates relative to the driving gear. Thus, during use, only need to first assemble the friction wire power module, sleeve the driving gear and the spring on the sleeve shaft, sleeve the pressure adjusting part on the sleeve shaft thread part, then the assembly of the friction wire power module can be completed, and then sleeve the fixing sleeve on the rotating shaft and use the fixing member to fix the fixing sleeve on the rotating shaft, then the installation of the friction wire power module on the rotating shaft can be completed. The structure is very simple and the installation is very convenient. Moreover, the frictional force received by the driving gear can be adjusted by adjusting the compression elastic force of the spring through the pressure adjusting part. In addition, when the driving gear stops rotating, the external force acting on the sleeve shaft by the rotating shaft overcomes the frictional force received by the driving gear, and the sleeve shaft rotates relative to the driving gear.

[0046] The following further elaborates the detailed implementation manners of the present invention in conjunction with the accompanying drawings:

[0047] Please refer to Figures 1 to 7 . The friction wire of the present invention includes a frame 1, a driving motor (not shown in the figure), a rotating shaft 2, a driven gear 3, a friction wheel 4, and a friction wire power module 5. Among them;

[0048] The frame 1 mainly serves as a support. The frame 1 generally includes two opposite support rods 11.

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

[0050] The rotating shaft 2 is connected to the driving motor and rotates under the drive of the driving 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 arranged outside the two support rods.

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

[0052] The friction wheel 4 is connected to the driven gear and rotates with the driven gear. In this specific embodiment, the driven gear is located outside the support rod, and the friction wheel is located inside the support rod. There are multiple driven gears and friction wheels, and they are evenly distributed parallel to 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 wire power module 5 includes a fixing sleeve 51, a fixing member 52, a driving gear 53, a spring 54, and a pressure regulating part 55.

[0054] Among them:

[0055] The fixing sleeve 51 includes a sleeve shaft 511 and a fixing boss 512 provided on the outer surface of the sleeve shaft and protruding outward. An axial rotation shaft hole 5111 centered on the central axis of the sleeve shaft is provided on the sleeve shaft 511; one end of the sleeve shaft 511 is provided with a sleeve shaft thread portion 5112, and an adjusting thread 5113 is further provided on the outer surface of the sleeve shaft thread portion 5112. The sleeve shaft is mainly used to assemble the driving gear, the spring and the pressure adjusting portion into a whole, so as to avoid the need for subsequent individual installation on the rotation shaft. The fixing boss mainly plays a blocking role, and together with the pressure adjusting portion, clamps the spring and the driving gear, so that the compression elastic force of the spring acts on the driving gear, so that when the rotation shaft rotates, friction force is generated on the driving gear. By adjusting the position of the pressure adjusting portion, the compression length of the spring can be adjusted, so as to adjust the pressure acting on the driving gear and the maximum friction force that can be generated on the driving gear. At the same time, the sleeve shaft can also facilitate the assembly of the driving gear and the spring, and only need to sleeved the driving gear and the spring on the sleeve shaft.

[0056] The fixing member 52 is connected to the fixing sleeve and fixes the fixing sleeve on the rotation shaft. After the fixing sleeve is sleeved on the rotation shaft, the fixing sleeve is fixed on the rotation shaft by the fixing member.

[0057] In this specific embodiment, the other end of the sleeve shaft 511 is provided with a fixing portion 513, the fixing boss is located between the fixing portion and the sleeve shaft thread portion, and an elastic groove 5131 penetrating the rotation shaft hole is opened on the outer surface of the fixing portion 513; the fixing member 52 includes a retaining ring 521 sleeved on the fixing portion and a fastening member (not shown in the figure) for clamping both ends of the retaining ring. The elastic groove is mainly used to enable the fixing portion to undergo elastic deformation, so as to fix the fixing portion on the rotation shaft.

[0058] Both ends of the retaining ring 521 are provided with screw holes 5211. The fastening member can be realized by using a screw or a bolt. The fastening member passes through the screw holes and presses and fixes the retaining ring on the fixing portion. At the same time, the pressure generated by the retaining ring acts on the fixing portion to fix the fixing portion on the rotation shaft. In this specific embodiment, the elastic grooves include a plurality of and are uniformly arranged around the fixing portion. An elastic piece 5132 is formed between two adjacent elastic grooves. The retaining ring is sleeved on the elastic piece. During the fastening process of the fastening member, the pressure generated by the retaining ring causes the elastic piece 5132 to undergo elastic deformation, so as to fix the fixing portion on the rotation shaft.

[0059] Of course, the fixing member can also directly use a screw to fix the fixing sleeve on the rotation shaft, or fix the fixing sleeve on the rotation shaft by means of pin fixing. However, since the method of fixing with a retaining ring is more convenient, the method of fixing with a retaining ring is preferably used.

[0060] The driving gear 53 includes a driving body 531 and driving teeth 532 provided on the outer surface of the driving body. The driving body is sleeved on the sleeve shaft. The driving teeth and the driven gear are conical teeth that mesh with each other, so that the steering of the movement can be realized. The driving gear and the driven gear can be made of metal or plastic.

[0061] The spring 54 is sleeved on the sleeve shaft. The spring is mainly used to generate compressive elastic force to press the driving body tightly. At the same time, the elastic force generated by the spring also acts on the pressure adjusting part to prevent the pressure adjusting part from accidentally loosening.

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

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

[0064] The driving motor drives the rotating shaft to rotate. The external force acting on the driving gear is balanced with the frictional force received by the driving gear. The driving gear rotates synchronously with the rotating shaft to drive the friction wheel to rotate. When the friction wheel is blocked by an external force and stops rotating, the driving gear stops rotating. At this time, when the external force applied by the rotating shaft to the sleeve shaft overcomes the frictional force received by the driving gear, the sleeve shaft rotates with the rotating shaft, and the sleeve shaft and the rotating shaft rotate relative to the driving gear. The friction wheel being blocked by an external force and stopping rotating can be achieved by blocking the movement of the carrier carrying the product. When it is necessary to stop the carrier at the current position, a first gear lever can be driven by a cylinder to block the carrier, so that the carrier stops moving, and thus the friction wheel stops rotating. At this time, the acting force of the friction wheel on the driving gear through the driven gear is greater than the frictional force received by the driving gear, and the driving gear stops rotating. The external force acting on the sleeve shaft overcomes the frictional force received by the driving gear, and the sleeve shaft continues to rotate with the rotating shaft, so as to rotate relative to the driving gear, without interfering with the rotation of the driving gears of other friction line power modules, and the unblocked carrier will continue to move.

[0065] There are multiple friction line power modules, which are evenly spaced along the rotating shaft; there are multiple driven gears and friction wheels, and they are arranged in one-to-one correspondence with the friction line power modules.

[0066] During use, only need to first assemble the friction line power module, sleevethe driving gear and the spring on the sleeve shaft, and sleevethe pressure adjusting part on the threaded part of the sleeve shaft, then the assembly of the friction line power module can be completed. Then sleevethe fixed sleeve on the rotating shaft and use a fixing part to fix the fixed sleeve on the rotating shaft, and the installation of the friction line power module on the rotating shaft can be completed. The structure is very simple and the installation is very convenient. Moreover, the frictional force received by the driving gear can be adjusted by adjusting the compression elastic force of the spring through the pressure adjusting part. In addition, since the external force applied by the rotating shaft to the sleeve shaft overcomes the frictional force received by the driving gear, the sleeve shaft rotates relative to the driving gear. Therefore, when it is necessary to pause the product at the current position, only need to block the rotation of the friction wheel, then the rotating shaft can rotate while the driving gear does not move, without interfering with the work of other friction line power modules.

[0067] In this specific embodiment, an axially arranged sleeve shaft positioning part 5114 is further provided on the outer surface of the sleeve shaft 511; 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 further includes a first friction gasket 56. The first friction gasket 56 is sleeved on the sleeve shaft and can axially move relative to the sleeve shaft. The first friction gasket is pressed by the spring between the fixed boss and the driving body of the driving gear; a first gasket positioning portion 561 corresponding to the sleeve shaft positioning portion is provided on the first friction gasket 56, and the first gasket positioning portion cooperates with the sleeve shaft positioning portion to prevent the first friction gasket from rotating relative to the sleeve shaft.

[0069] Through the setting of the first friction gasket, the direct contact between the driving gear body and the fixed boss can be avoided. At the same time, since the first friction gasket cooperates with the sleeve shaft positioning portion through the first gasket positioning portion, the first friction gasket will not rotate relative to the sleeve shaft. Therefore, when the driving gear and the rotating shaft rotate relative to each other, the fixed boss will not be worn, so as to damage the sleeve shaft. When the first friction gasket or the driving gear needs to be replaced due to wear, only the first friction gasket or the driving gear needs to be replaced, thus greatly reducing the use and maintenance costs.

[0070] In this specific embodiment, a recessed gasket groove 533 is provided at one end of the driving body 531, and the depth of the gasket groove is less than the thickness of the first friction gasket. One end of the first friction gasket is inserted into the gasket groove, and the other end abuts against one side of the fixed boss. By setting the gasket groove and making the depth of the gasket groove less than the thickness of the first friction gasket, the structure of the entire friction line power module can be made more compact, the size can be smaller, and the appearance can be more beautiful.

[0071] In this specific embodiment, a driving sleeve hole 5311 penetrating through both ends of the driving body is provided on the driving body 531. The driving sleeve hole is sleeved on the sleeve shaft, and recessed grooves 5331 which are spaced apart and penetrate to the driving sleeve hole are provided at the bottom of the gasket groove 533.

[0072] The setting of the grooves can effectively conduct and dissipate the heat generated between the first friction gasket and the driving body through the grooves, which is beneficial to heat dissipation and avoids damage to the first friction gasket and the driving gear caused by heat accumulation. At the same time, the setting of the grooves can also increase the maximum friction force between the first friction gasket and the driving body and improve the driving force.

[0073] In this specific embodiment, the sleeve positioning portion 5114 is a planar portion formed by axially cutting the outer surface of the sleeve; a gasket hole 562 is provided at the center of the first friction gasket 56, and the first friction gasket is sleeved on the sleeve through the gasket hole. The first gasket positioning portion 561 is a gasket boss extending inward from the gasket hole and having a planar inner side surface. When the first friction gasket is sleeved on the sleeve, the inner side plane of the gasket boss faces the planar portion, thereby preventing the first friction gasket from rotating relative to the sleeve. Of course, the sleeve positioning portion can also be set as a recessed positioning groove opened on the sleeve, and the first gasket positioning portion is a protruding positioning piece, and the positioning piece is inserted into the positioning groove to prevent the first friction gasket from rotating relative to the sleeve.

[0074] In this specific embodiment, the friction line power module further includes a second friction gasket 57. The second friction gasket 57 is sleeved on the sleeve and can axially move relative to the sleeve. The second friction gasket is pressed by the spring between the driving body of the driving gear and the spring; a second gasket positioning portion 571 corresponding to the sleeve positioning portion is provided on the second friction gasket 57, and the second gasket positioning portion cooperates with the sleeve positioning portion to prevent the second friction gasket from rotating relative to the sleeve. The structure of the second friction gasket is the same as that of the first friction gasket. The provision of the second friction gasket can prevent the driving body from directly contacting the spring, and avoid wear on the spring when the driving gear rotates relative to the sleeve. Thus, in later maintenance, only the second friction gasket needs to be replaced, rather than the spring, thereby greatly reducing the use and maintenance costs. At the same time, the structure of the second friction gasket is the same as that of the first friction gasket, and there is no need to distinguish during installation, which is convenient for manufacturing and installation.

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

[0076] In this specific embodiment, the pressure adjustment part 55 includes an adjustment body 551, a threaded hole 552, a spring arm groove 553, a resilient arm 554, and a positioning arm 555. Among them:

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

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

[0079] The spring arm groove 553 is provided at one end of the adjustment body and is recessed outward from the inner side surface of the threaded hole.

[0080] The resilient arm 554 is provided in the spring arm groove and extends along the axial direction of the adjustment body from the side surface of the spring arm groove.

[0081] The positioning arm 555 extends from one end of the resilient arm away from the bottom surface of the spring arm groove in the radial direction of the adjustment body towards the center of the circle; a positioning convex 5551 is provided at the end of the positioning arm 555.

[0082] The fixed sleeve 51 further includes an inwardly recessed positioning card slot 514 provided along the axial direction of the sleeve shaft and on the sleeve shaft threaded part; the positioning convex can be inserted into the positioning card slot to prevent the pressure adjustment part from rotating relative to the sleeve shaft threaded part without external force, and when the adjustment body is rotated by an external force, the positioning convex can be screwed out of the positioning card slot and rotate together with the adjustment body. In this specific embodiment, both the positioning convex and the positioning card slot are of a sharp angle type. By using the two inclined surfaces of the sharp angle, it is convenient for the positioning convex to be disengaged from the positioning card slot.

[0083] The resilient arm can deform, so as to facilitate the positioning convex to be disengaged from the positioning card slot when the adjustment body is rotated. When the positioning convex is stuck in the positioning card slot, it can prevent the pressure adjustment part from rotating relative to the sleeve shaft. Combined with the threaded connection between the pressure adjustment part and the sleeve shaft threaded part, it can effectively prevent the loosening of the pressure adjustment part. When it is necessary to adjust the compression elastic force of the spring, rotate the adjustment body forcefully. Since the resilient arm can deform, the positioning convex is disengaged from the positioning card slot and rotates together with the adjustment body, thereby realizing the movement of the pressure adjustment part relative to the sleeve shaft threaded part and adjusting the compression length of the spring.

[0084] In the present invention, by providing a fixed sleeve, a fixing member, a driving gear, a spring, a pressure adjusting part, a first friction gasket, a second friction gasket and a third friction gasket, during installation, it is only necessary to sequentially sleeved the first friction gasket, the driving gear, the second friction gasket and the spring on the sleeve shaft of the fixed sleeve, and then thread the pressure adjusting part onto the threaded part of the sleeve shaft of the sleeve shaft. Then, the clamping ring of the fixing member is sleeved on the fixing part of the fixed sleeve, and the installation of the friction line power module can be completed. The overall structure is very simple and the installation is convenient.

[0085] When installed on a friction line, it is only necessary to sleeve the entire friction line power module on the rotating shaft, and then use the fixing member to fix the fixed sleeve on the rotating shaft, and the installation of the friction line power module on the rotating shaft can be completed. The structure is very simple and the installation is also very convenient. Moreover, the compression elastic force of the spring can be adjusted through the pressure adjusting part to adjust the friction force received by the driving gear. In addition, when the external force acting on the sleeve shaft overcomes the friction force received by the driving gear, the sleeve shaft rotates relative to the driving 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, so that the rotating shaft rotates while the driving gear does not move, without interfering with the work of other friction line power modules.

[0086] The structure of the present invention is simple and the installation is convenient. Moreover, the compression length of the spring can be conveniently adjusted through the pressure adjusting part to adjust the pressure received by the driving gear, thereby adjusting the driving force. After the friction power module is installed on the friction line, the pressure received by the driving gear can be very conveniently adjusted according to the actual situation.
