Description

Technical Field

[0001] This invention belongs to the field of fabric winding technology, specifically a winding device for toy fabric production. Background Technology

[0002] As a crucial component in toy manufacturing, the material and properties of toy fabric directly impact the toy's appearance, feel, and safety. After the toy fabric is produced, it needs to be wound up using a winding device, which consists of a winding roller mechanism and a guide roller mechanism to keep the fabric flat during the winding process. Before winding the toy fabric, it needs to be wound around the guide rollers (as shown in the attached image). Figure 11 (As shown) the winding roller can only be connected after the guide rollers are in groups and appear alternately, making the operation of winding the toy fabric onto the guide rollers difficult and time-consuming. Therefore, to solve the above problems, a winding device for toy fabric production is proposed. Summary of the Invention

[0003] To address the problems mentioned in the background art, the present invention provides a winding device for toy fabric production, which solves the problems of high difficulty and time consumption in winding toy fabric onto guide rollers.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a winding device for toy fabric production, comprising a support assembly and a second guide roller, wherein the support assembly includes a bracket and a first guide roller equidistantly connected to the bracket, and toy fabric is wound around the first guide roller; further comprising: a pressure roller mechanism movably sleeved on one end of the first guide roller; a drive linkage disposed on the support assembly for driving the pressure roller mechanism to rotate; and a release assembly equidistantly fixed to the bracket. The release component includes stops that are equidistantly fixed to the bracket; The pressure roller mechanism includes a third link, a fourth link, and a connecting assembly. The third link is movably sleeved on the first guide roller. One end of the fourth link is hinged to the third link. The second guide roller is movably sleeved on one end of the fourth link. The connecting assembly is fixed to the third link to keep the third link and the fourth link in a straight line. A straight groove is provided on the third link. The drive linkage includes a hydraulic rod hinged to one end of the bracket and a first linkage. A second linkage is also movably connected in the groove at the top of the stop block. Pins are fixedly connected to the second linkage at equal intervals. The hydraulic rod retracts, causing its top end to rotate around the hinge point between the first connecting rod and the bracket. When the first connecting rod rotates, it causes the pin inside to move horizontally toward the hydraulic rod, and through the second connecting rod, it causes the remaining pins to slide inside the straight groove. This causes the pressure roller mechanism to drive the second guide roller to rotate clockwise around the first guide roller, pressing down the toy fabric.

[0005] Preferably, the second guide roller is initially located above the first guide roller, and the second guide roller is located below the first guide roller after the pressing roller mechanism drives the second guide roller to rotate and presses the toy cloth.

[0007] Preferably, the connecting assembly comprises a connecting block fixed to one side of the third connecting rod, and an elastic clamping block elastically connected to the inside of the connecting block. One end of the elastic clamping block is clamped into a clamping groove provided on the fourth connecting rod.

[0009] Preferably, the two ends of the elastic clamping block are provided with chamfers, and one end of the elastic clamping block away from the fourth connecting rod is blocked by the blocking block and keeps the other end clamped into the clamping groove.

[0010] Preferably, the releasing assembly further comprises a groove provided in the bottom of the blocking block. When the pressing roller mechanism rotates to the maximum angle, the third connecting rod drives the elastic clamping block to be on the same axis with the groove through the connecting block, one end of the elastic clamping block is clamped into the groove under the action of its own elastic force, and the other end of the elastic clamping block is separated from the clamping groove.

[0011] Preferably, the depth of the groove gradually increases from the top end to the bottom end.

[0012] Preferably, the pressing roller mechanism further comprises an elastic sheet fixed to the top end of the third connecting rod for supporting the fourth connecting rod.

[0013] Preferably, the third connecting rod further comprises a blocking plate fixed to one end of the third connecting rod, and the fourth connecting rod further comprises a protruding column abutting against the upper surface of the blocking plate.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 11 As shown, the present invention provides a winding device for toy fabric production, including a support assembly 1 and a second guide roller 5. The support assembly 1 includes a bracket 11 and a first guide roller 12 equidistantly connected to the bracket 11. Toy fabric 6 is also wound around the first guide roller 12. The device further includes: a pressure roller mechanism 3, which is movably sleeved on one end of the first guide roller 12; a drive linkage 2, which is disposed on the support assembly 1 for driving the pressure roller mechanism 3 to rotate; and a release assembly 4, which is equidistantly fixed to the bracket 11. Among them, the release component 4 includes a stop 41 that is equidistantly fixed to the bracket 11; The pressure roller mechanism 3 includes a third connecting rod 31, a fourth connecting rod 32, and a connecting assembly 33. The third connecting rod 31 is movably sleeved on the first guide roller 12. One end of the fourth connecting rod 32 is hinged to the third connecting rod 31. The second guide roller 5 is movably sleeved on one end of the fourth connecting rod 32. The connecting assembly 33 is fixedly connected to the third connecting rod 31 to keep the third connecting rod 31 and the fourth connecting rod 32 in a straight line. A straight groove 311 is provided on the third connecting rod 31. The drive link 2 includes a hydraulic rod 21 hinged to one end of the bracket 11 and a first link 22. A second link 23 is also movably connected in the groove at the top of the stop block 41. Pins 231 are fixedly connected to the second link 23 at equal intervals. The hydraulic rod 21 retracts, causing its top end to drive the top end of the first connecting rod 22 to rotate around the hinge point between the first connecting rod 22 and the bracket 11. When the first connecting rod 22 rotates, it drives the pin 231 inside to move horizontally toward the hydraulic rod 21, and through the second connecting rod 23, it drives the remaining pins 231 to slide inside the straight groove 311, thereby causing the pressure roller mechanism 3 to drive the second guide roller 5 to rotate clockwise around the first guide roller 12 to press down the toy fabric 6. With the above scheme, the toy cloth 6 is spread out and placed on the first guide roller 12, the hydraulic rod 21 pushes the first connecting rod 22 to rotate, and the second connecting rod 23 is pulled to move through the cooperation of the first connecting rod 22 and the internal pin shaft 231. At this time, due to the limiting of the stop block 41 in the vertical direction of the second connecting rod 23, the second connecting rod 23 drives the remaining pin shafts 231 to slide in the straight groove 311 respectively and forces the compression roller mechanism 3 to rotate as a whole, thereby making the compression roller mechanism 3 drive the second guide roller 5 to rotate counterclockwise to the lower side of the first guide roller 12 and press down the toy cloth 6, completing the operation of winding the toy cloth 6 around the roller; It is worth noting that the design of the connecting assembly 33 ensures the integrity of the third connecting rod 31 and the fourth connecting rod 32, so that when the compression roller mechanism 3 is pressed down on the toy cloth 6 as a whole, the angle of rotation and the distance of descent of the second guide roller 5 driven by each group of compression roller mechanisms 3 are equal. Avoiding the different frictional forces of the toy cloth 6 on the second guide roller 5 of each group of compression roller mechanisms 3, each fourth connecting rod 32 can rotate independently when pressing down on the toy cloth 6, thereby reducing the situation that the stroke of each fourth connecting rod 32 is inconsistent when the subsequent toy cloth 6 shrinks too fast.

[0019] As shown in Figures 1-3 , the second guide roller 5 is initially located above the first guide roller 12, and after the compression roller mechanism 3 drives the second guide roller 5 to rotate and press down the toy cloth 6, the second guide roller 5 is located below the first guide roller 12; The first guide roller 12 near the hydraulic rod 21 is used for guiding out the toy cloth 6, and the outside of which is not sleeved with the compression roller mechanism 3; With the above scheme, when the second guide roller 5 is above the first guide roller 12, it is convenient for people to place the toy cloth 6 on the first guide roller 12, and when the second guide roller 5 is lowered to the lower side of the first guide roller 12, it can press down the toy cloth 6, thereby simplifying the complex winding operation.

[0020] As shown in Figures 1-3 and Figures 5-9 , the connecting assembly 33 includes a connecting block 331 fixed to one side of the third connecting rod 31; an elastic clamping block 333 elastically connected to the inside of the connecting block 331; one end of the elastic clamping block 333 is clamped into a clamping groove 332 provided on the fourth connecting rod 32; The cross sections of the clamping groove 332 and the two ends of the elastic clamping block 333 are hexagonal, the end of the elastic clamping block 333 away from the clamping groove 332 is limited by the circumferential wall of the connecting block 331, and the elastic clamping block 333 has an axial movement tendency under the action of its own elastic force; The two ends of the elastic clamping block 333 are provided with chamfers, and the end of the elastic clamping block 333 away from the fourth connecting rod 32 is blocked by the stop block 41 and keeps the other end clamped into the clamping groove 332; Adopting the above scheme, through the design of the hexagonal section of the elastic clamping block 333 at both ends, since the elastic clamping block 333 is limited in the circumferential direction by the inner wall of the connecting block 331, when the other end of the elastic clamping block 333 is clamped into the clamping groove 332, the rotation of the fourth connecting rod 32 at the hinge with the third connecting rod 31 is avoided. It is worth noting that through the design of the connecting assembly 33, the collinearity of the third connecting rod 31 and the fourth connecting rod 32 is ensured, thereby avoiding the rotation of the fourth connecting rod 32 at the hinge with the third connecting rod 31 when the pressure roller mechanism 3 drives the second guide roller 5 to press down on the toy fabric 6.

[0021] As shown in Figures 1-3 and Figures 7-10 , the release assembly 4 further comprises a groove 42 opened at the bottom of the stop block 41; When the pressure roller mechanism 3 rotates to the maximum angle, the third connecting rod 31 drives the elastic clamping block 333 through the connecting block 331 to be on the same axis as the groove 42, one end of the elastic clamping block 333 is clamped into the groove 42 due to its own elastic force, and the other end of the elastic clamping block 333 is separated from the clamping groove 332; The depth of the groove 42 gradually increases from the top end to the bottom end; The pressure roller mechanism 3 further comprises a spring piece 34 fixed to the top end of the third connecting rod 31 for supporting the fourth connecting rod 32; Adopting the above scheme, when the contact end of the elastic clamping block 333 slides to the groove 42, the elastic clamping block 333 is clamped into the groove 42 due to its own elastic force, and the other end of the elastic clamping block 333 is separated from the clamping groove 332, at this time the fourth connecting rod 32 can rotate around the hinge with the third connecting rod 31, therefore when the winding mechanism winds the toy fabric 6 too fast, the toy fabric 6 will force the fourth connecting rod 32 to rotate through the second guide roller 5, and the spring piece 34 will be compressed, at this time the travel of the toy fabric 6 will be shortened, to avoid the deformation of the toy fabric 6 due to excessive tension when it is wound quickly; It is worth noting that when the device needs to be reset, at this time the operating hydraulic rod 21 is elongated, which can make the pressure roller mechanism 3 rotate counterclockwise as a whole, and the end of the elastic clamping block 333 clamped into the groove 42 is gradually separated from the groove 42 and abuts against the stop block 41, during this process the inner wall of the groove 42 will force the elastic clamping block 333 to shrink into the connecting block 331, and the other end of the elastic clamping block 333 will be gradually clamped into the clamping groove 332, thereby maintaining the integrity of the third connecting rod 31 and the fourth connecting rod 32, which is helpful for the subsequent pressing and winding of the toy fabric 6 by the device.

[0022] As shown in Figures 5-6 and Figures 8-9As shown, the third connecting rod 31 is further fixed with a baffle 312 at one end of the fourth connecting rod 32, and the fourth connecting rod 32 is further fixed with a protruding column 321 abutting the upper surface of the baffle 312; By adopting the above scheme, the protruding column 321 is blocked by the baffle 312, so as to avoid the occurrence of the case that the fourth connecting rod 32 rotates clockwise with the hinge joint of the third connecting rod 31 as the axis, and meanwhile, when the toy cloth 6 is completely rolled up, the fourth connecting rod 32 is reset by the elastic piece 34, so as to ensure that the third connecting rod 31 and the fourth connecting rod 32 are on the same straight line.

[0023] Working principle and use process of the present application: Firstly, the operator spreads the toy cloth 6 and places it on the first guide roller 12, the hydraulic rod 21 pushes the first connecting rod 22 to rotate, and the first connecting rod 22 and the internal pin shaft 231 cooperate to pull the second connecting rod 23 to move, so that the second connecting rod 23 drives the remaining pin shafts 231 to slide in the straight groove 311 and forces the compression roller mechanism 3 to rotate as a whole, and then the compression roller mechanism 3 drives the second guide roller 5 to rotate counterclockwise to the lower side of the first guide roller 12 and press the toy cloth 6; In the process of rotating the third connecting rod 31, the fourth connecting rod 32 is also driven to rotate through the connecting assembly 33, the elastic clamping block 333 first contacts the baffle 41 and then contacts the second connecting rod 23, and finally contacts the baffle 41 again, when the elastic clamping block 333 contacts one end of the baffle 41 and slides to the recess 42, the elastic clamping block 333 is clamped into the recess 42 under the action of its own elastic force, and the other end of the elastic clamping block 333 is separated from the clamping groove 332, at this time, the fourth connecting rod 32 can rotate with the hinge joint of the third connecting rod 31 as the axis.
