DETAILED DESCRIPTION

[0027] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0028] Referring to Figures 1-7 As shown in the figure: a fixing device for quilt production, including rack 1, linear module 2 installed at both ends of rack 1 and sewing assembly 3 provided in linear module 2, clamping mechanism 4 is provided between linear module 2, clamping mechanism 4 includes clamping base 41, first motor 42 is installed on clamping base 41, the output shaft of first motor 42 is connected with first gear 43, first gear 43 is connected with second gear 44 in meshing, second gear 44 is connected with rotating shaft 45, third gear 46 is provided at the head and tail ends of rotating shaft 45, third gear 46 is connected with fourth gear 47 in meshing, fourth gear 47 is connected with fixed sleeve 48, rotating shaft is provided at the head and tail ends of clamping base 41, fixed sleeve 48 is sleeved on the rotating shaft on clamping base 41, mounting block 481 is provided on the circumferential surface of fixed sleeve 48, clamping block 482 is installed on mounting block 481, mounting hole is formed in mounting block 481 and clamping block 482, clamping block 482 is installed on mounting block 481 through bolts.

[0029] The clamping device in the prior art has poor stability and needs manual operation to open and close the clamping device. To solve this problem, the fixing and adjustment of the quilt are realized by the cooperation of mechanical transmission and clamping structure in the present application. The linear module 2 at both ends of the rack 1 is controlled by the program to make the sewing assembly 3 translate along the module axis, so that it can cover the quilting area of the quilt and keep the path accurate. The core power of the clamping mechanism 4 comes from the first motor 42 on the clamping base 41, the output shaft of the first motor 42 is connected with the second gear 44 in meshing through the first gear 43 for one-stage transmission, driving the rotating shaft 45 to rotate. The third gear 46 and the fourth gear 47 at both ends of the rotating shaft 45 are engaged to form two-stage transmission, and through the rotation of the first motor 42, the stability of the clamping action is ensured.

[0030] The fixed sleeve 48 is driven to rotate around the rotation shaft by the fourth gear 47, and the mounting block 481 on the circumferential surface of the fixed sleeve 48 rotates synchronously. The mounting block 481 is connected with the clamping block 482 through bolts, and the radial position of the clamping block 482 can be adjusted according to the rotation angle of the fixed sleeve 48. When the fixed sleeve 48 rotates, the clamping block 482 moves along the circumferential track inward or outward, completing the clamping or releasing of the quilt edge. The bolt connection design allows quick replacement of the clamping block 482 according to the thickness or material of the quilt. During the sewing process, the clamping mechanism 4 first clamps and positions the quilt edge, and then the linear module 2 drives the sewing assembly 3 to move. The synchronization of the gear transmission ensures that the clamping blocks 482 at both ends move consistently, avoiding the offset of the quilt during sewing. Through the coordination of the electrical control system, the clamping and sewing actions are realized, achieving an automatic production process.

[0031] Referring to Figures 1-7 As shown: the rack 1 is provided with a through slot, and the adjusting mechanism 5 is installed in the through slot. The adjusting mechanism 5 includes a bidirectional threaded rod 51 arranged in the through slot, and mounting bases 52 for mounting clamping bases 41 are threadedly connected to both ends of the bidirectional threaded rod 51. The bidirectional threaded rod 51 is driven by a second motor 53.

[0032] The adjusting mechanism 5 realizes flexible adjustment of the distance between the clamping bases 41 through the cooperation of the bidirectional threaded rod 51 and the motor. The bidirectional threaded rod 51 transversely penetrates the through slot, and its two ends are threadedly connected with the two mounting bases 52, respectively. When the second motor 53 drives the bidirectional threaded rod 51 to rotate, the two mounting bases 52 will move synchronously and reversely along the axial direction of the through slot due to the opposite rotation directions of the threads at both ends of the bidirectional threaded rod 51.

[0033] When it is necessary to adapt to quilts of different sizes, the second motor 53 is started to drive the bidirectional threaded rod 51 to rotate, and the mounting bases 52 are driven by the threads to move towards the center or separate to both sides, thereby changing the distance between the clamping bases 41 so that the clamping mechanism 4 can automatically adjust the clamping range according to the width of the quilt, ensuring that the clamping blocks 482 always act on the quilt edge accurately. The self-locking property of the threaded transmission can keep the positions of the mounting bases 52 stable after adjustment, avoiding displacement due to vibration during sewing.

[0034] When the adjusting mechanism 5 and the clamping mechanism 4 work together, the clamping bases 41 are first adjusted to the target distance by the second motor 53, and then the clamping action is completed by the first motor 42 driving the clamping blocks 482. The symmetrical design of the bidirectional threaded rod 51 ensures the synchronous movement of the two clamping bases 41, avoiding uneven force on the quilt due to unilateral offset. Through integrated control of the electrical system, the adjustment process can be linked with the stroke parameters of the sewing machine 32, realizing fully automatic production of multiple specifications of quilts.

[0035] Referring to Figures 1-5As shown: the mounting base 52 is provided with a positioning slot 521, the clamping base 41 is provided with a positioning plug 411 matched with the positioning slot 521, the positioning plug 411 is inserted into the positioning slot 521, and the clamping base 41 is mounted on the mounting base 52 by bolts.

[0036] The positioning slot 521 on the mounting base 52 extends along the length direction, and the cross-sectional shape matches that of the positioning plug 411 at the bottom of the clamping base 41. During installation, the operator vertically inserts the positioning plug 411 of the clamping base 41 into the positioning slot 521 of the mounting base 52, and the close fit of the plug and the slot can limit the horizontal freedom degree of the clamping base 41, avoiding its deviation in the horizontal or vertical direction, thereby ensuring the initial positioning accuracy of the clamping base 41 and the mounting base 52.

[0037] When adjusting the distance between the clamping bases 41, the mounting base 52 is driven to move along the through slot by the bidirectional threaded rod 51, and the clamping base 41 is synchronously slid in the positioning slot 521 by the positioning plug 411 at the bottom. The guiding effect of the slot on the plug makes the moving track of the clamping base 41 strictly aligned with the movement axis of the adjusting mechanism 5, preventing deviation caused by transmission error. After completing the position adjustment, the operator locks and fixes the clamping base 41 and the mounting base 52 by bolts, forming a mechanical hard connection. The locking force of the bolts and the friction force of the plug-slot jointly act to resist vibration or pulling in sewing operation, ensuring the stability of the clamping base 41 under dynamic working conditions.

[0038] Referring to Figures 1-4 As shown: the through slot is provided with a limiting block 11 at the center position, the limiting block 11 is provided with a limiting through slot 111, and the bidirectional threaded rod 51 is provided with a limiting ring 511 at the center position, and the limiting ring 511 is rotationally connected with the limiting through slot 111.

[0039] The limiting block 11 at the center position of the through slot serves as a fixed reference, the limiting through slot 111 on the limiting block 11 is a transversely penetrating structure, and the limiting ring 511 at the center position of the bidirectional threaded rod 51 forms a rotational pair with the limiting through slot 111. When the second motor 53 drives the bidirectional threaded rod 51 to rotate, the limiting ring 511 rotates around its own axis in the limiting through slot 111, but the axial movement is completely blocked by the limiting block 11, thereby avoiding axial movement of the threaded rod due to uneven force or vibration.

[0040] Referring to Figures 1-4 As shown: the sewing assembly 3 includes a support frame 31 and a sewing machine 32 mounted on the support frame 31, and the support frame 31 is inserted into the linear module 2.

[0041] Support frame 31 is inserted into the slide rail or slide block of linear module 2 as the mounting base of sewing machine 32. Linear module 2 controls the axial translation of support frame 31 along the axis of linear module 2 through internal driving devices such as servo motors and ball screws, thereby driving the movement of sewing machine 32 along the preset trajectory within the length range of linear module 2.

[0042] Referring to Figures 1-4 As shown in the figure, the support frame 31 is provided with a transverse module 6, and the transverse module 6 is slidably connected with the sewing machine 32.

[0043] The transverse module 6 installed on the support frame 31 is arranged perpendicular to the linear module 2, forming a two-dimensional motion plane. The transverse module 6 usually integrates slide rail, slide block or ball screw structure inside, and the sewing machine 32 is slidably connected with the transverse module 6 through the slide block. When the driving part of the transverse module 6 such as the stepping motor is started, the sewing machine 32 can translate along the axis of the transverse module 6, and after superimposing the longitudinal motion of the linear module 2, it forms an arbitrary trajectory motion in the plane.

[0044] Referring to Figures 1-7 As shown in the figure, the facing surface of the clamping base 41 is provided with a guide rail 412, and the placing rack 413 for placing the quilt is slidably connected on the guide rail 412.

[0045] The placing rack 413 spans two clamping bases 41, and its top surface is used to place the quilt. During the sewing process, the relative position of the quilt in the horizontal plane can be adjusted by sliding along the guide rail 412, ensuring that the sewing area is always flat.

[0046] Referring to Figures 1-4 As shown in the figure, the end of the guide rail 412 away from the first motor 42 is provided with a baffle.

[0047] The end of the guide rail 412 away from the first motor 42 is fixedly installed with a baffle, and the height of the baffle is usually slightly higher than the top surface of the guide rail 412, forming a hard blocking surface perpendicular to the rail. When the support frame 31 slides along the guide rail 412, the slide block or ball guide rail at the bottom of the support frame 31 will contact the baffle when approaching the end of the rail, and the movement is forcibly terminated.

[0048] Working principle: The quilt production fixing device realizes self-adaptive clamping, accurate sewing and efficient production through the cooperation of multi-stage mechanical transmission and automatic control system. The built-in driving devices such as servo motors and ball screws in the linear modules 2 at both ends of the rack 1 control the axial translation of the support frame 31 of the sewing assembly 3, so that the sewing machine 32 covers the quilting area. The clamping mechanism 4 is located between the two linear modules 2, and its core is driven by the first motor 42: the output shaft of the first motor 42 drives the first gear 43 and the second gear 44 to mesh with the rotating shaft 45 through one-stage gear transmission, and the third gear 46 and the fourth gear 47 at both ends of the shaft mesh to form two-stage transmission, and finally drive the fixed sleeve 48 to rotate around the rotating shaft on the clamping base 41. The mounting block 481 on the circumference of the fixed sleeve 48 moves synchronously with the rotation, driving the clamping block 482 to clamp inward or release outward along the circular trajectory, and the synchronous nature of gear transmission ensures that the clamping actions on both sides are consistent, avoiding the deviation of the quilt.

[0049] To adapt to different sizes of quilts, the rack 1 is provided with a two-way threaded rod 51 adjusting mechanism 5 in the through slot. When the second motor 53 drives the two-way threaded rod 51 to rotate, the reverse threads at both ends cause the mounting base 52 to move synchronously in the opposite direction. The mounting base 52 is matched with the positioning insert block 411 of the clamping base 41 through the positioning slot 521: the insert block is vertically inserted into the slot to limit the horizontal degree of freedom, ensuring that the clamping base 41 moves accurately along the trajectory when the mounting base 52 moves; after adjustment, it is locked by bolts, forming a double stable structure of insert block guidance and bolt fixation. The center of the through slot is provided with a limiting block 11, and the limiting through slot 111 and the limiting ring 511 of the two-way threaded rod 51 constitute a rotating pair, which allows the rod to rotate and limits the axial movement, avoiding transmission errors caused by the deviation or vibration of the threaded rod.

[0050] The sewing assembly 3 is inserted into the linear module 2 through the support frame 31 to realize longitudinal movement, and the additional transverse module 6 on the support frame 31 integrates the slide rail and the driving part to enable the sewing machine 32 to move horizontally, forming a two-dimensional plane movement capability. The control system coordinates the motion parameters of the linear module 2 and the transverse module 6, so that the needle of the sewing machine 32 accurately follows the complex quilting path. The sliding connection of the transverse module 6 supports manual quick adjustment of the position of the sewing machine 32, facilitating maintenance or replacement of the head.

[0051] The opposite faces of the clamping base 41 are provided with guide rails 412, and the placing rack 413 is slidingly connected with the rails through the bottom block. When the clamping distance is adjusted, the placing rack 413 expands or contracts along the rail to maintain the support area of the quilt, preventing the middle part from sagging. The end of the guide rail 412 is provided with a baffle, which limits the movement range of the placing rack 413 through a hard blocking surface, and the contact surface is made of a cushioning material to reduce impact noise. The baffle is designed to be detachable to adapt to the processing needs of quilts of different sizes, and also serves as a visual positioning mark to assist operation.

[0052] The whole system is integrated and coordinated by an electrical control system: during production, the second motor 53 drives the bidirectional threaded rod 51 to adjust the distance between the clamping bases 41 to the width of the quilt, and then the first motor 42 drives the clamping blocks 482 to clamp the quilt; the linear module 2 and the transverse module 6 drive the sewing machine 32 to work according to the preset trajectory. The self-locking characteristic of the threaded transmission, the hard limit of the block-slot and the mechanical blocking of the baffle jointly guarantee the stability under the dynamic working condition, and realize the efficient production of the full-automatic multi-specification quilt.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
