Description

Technical Field

[0001] This utility model relates to the technical field of quilting machines, specifically to a quilting machine frame. Background Technology

[0002] A quilting machine is a specialized sewing device used for quilting multi-layered textile fabrics such as quilts, bedspreads, or cotton clothing. The core function of a quilting machine is to securely sew together the outer fabric filling (such as cotton, down, or sponge) and the underlying fabric by sewing decorative or functional reinforcing stitches, creating a three-dimensional, fluffy, and aesthetically pleasing quilted product. The quilting machine's frame is a crucial component used to hold and unfold the quilted fabric, ensuring it is flat and wrinkle-free for precise sewing.

[0003] The shortcomings of existing technology: The frame of the quilting machine described above includes four support plates connected end to end to form a square frame. Each support plate is equipped with several clamps, which are evenly distributed along the length of the support plate. One side of each clamp is connected to the support plate, and the other side is used to clamp the quilted fabric. Since the clamps are fixedly connected to the support plates, when the operator processes quilted fabrics of different sizes, the clamps can only hold a limited amount of quilted fabric, making it difficult to clamp large-sized quilted fabrics. In this case, the operator needs to frequently manually adjust the position of the fabric to clamp it. This process can easily reduce production efficiency, and the increased manual intervention can easily introduce operational errors. Utility Model Content

[0019] Please see Figure 1-6 As shown, this utility model provides a technical solution for the tensioning frame of a quilting machine: A quilting machine frame includes four support plates 1. Each horizontally arranged support plate 1 has a connector installed at its end. The four support plates 1 are connected end to end by the connectors, forming a square frame. Each support plate 1 has a horizontally formed support groove 12 on its side wall. The connector includes a drive block 14 and a drive rod 13. One end of the drive rod 13 extends into the support groove 12 and is slidably connected to the side wall of the support groove 12. The other end of the drive rod 13 is fixedly connected to the drive block 14. The side wall of the horizontally arranged drive block 14 is fixedly connected to the adjacent drive block 14.

[0020] Each support plate 1 is equipped with a first slide rail 21, a second slide rail 22 and a slider 3 on its top. The bottom of the horizontally arranged first slide rail 21 is fixedly connected to the top of the support plate 1. There are two horizontally arranged second slide rails 22, and both second slide rails 22 are located on both sides of the upper surface of the first slide rail 21. A transmission cavity for the slider 3 to slide is provided between each second slide rail 22 and the first slide rail 21. A transverse groove 23 is horizontally opened on the side wall of the second slide rail 22, and a vertical groove 24 is horizontally opened on the top of the second slide rail 22. The horizontally arranged slider 3 includes a first slider 31 and a second slider 32. Each first slider 31 and second slider 32 is in the shape of an "I". There are two first sliders 31, and the two first sliders 31 are located at the ends of the second slide rail 22 away from the first slide rail 21. The first sliders 31 are fixedly connected to the second slide rail 22. There are several second sliders 32, and the second sliders 32 are evenly distributed along the length direction of the first slide rail 21. The bottom and top of the second sliders 32 are slidably connected to the first slide rail 21. A transmission mechanism 4 is installed on the first slide rail 21. The transmission mechanism 4 includes a telescopic rod 41 and a transmission spring 42. The horizontally arranged telescopic rod 41 is located inside the first slide rail 21, and the telescopic rod 41 extends and retracts along the length direction of the first slide rail 21. The side wall of the telescopic rod 41 passes through the second slider 32 and is slidably connected to the second slider 32. The two ends of the telescopic rod 41 are fixedly connected to the side walls of the two first sliders 31. The transmission spring 42 is located within two adjacent second sliders 32, and the ends of the transmission spring 42 are fixedly connected to the side walls of the second slider 32 or the first slider 31, respectively. Each first slider 31 and second slider 32 is equipped with a clamping clip 11. One side of the clamping clip 11 is slidably connected to the side wall of the transverse groove 23, and the other side of the clamping clip 11 is used to clamp the quilted fabric.

[0021] Each of the first slider 31 and the second slider 32 has a vertically formed abutment groove 71 at its top. Each of the first slider 31 and the second slider 32 is equipped with an abutment member 5 and a limiting rod 92. The abutment member 5 includes an abutment spring 51, an abutment rod 52, a telescopic plate 53, and an abutment screw 54. There are multiple abutment springs 51 and abutment rods 52, and each vertically arranged abutment spring 51 is located within the abutment groove 71. The bottom of the abutment spring 51 is fixedly connected to the bottom wall of the abutment groove 71, and the top of the abutment spring 51 is fixedly connected to the bottom of the abutment rod 52. The bottom of the connecting rod 52 extends into the abutment groove 71 and is slidably connected to the side wall of the abutment groove 71. The top of the abutment rod 52 is slidably connected to the vertical groove 24 passing through the second slide rail 22 and to the side wall of the vertical groove 24. The horizontally arranged telescopic plate 53 is located at the top of the abutment rod 52, and the bottom of the telescopic plate 53 abuts against the top of the abutment rod 52. The telescopic plate 53 extends and retracts along the length of the support plate 1. The vertically arranged abutment screw 54 is rotatably connected to the top of the support plate 1, and the top of the abutment screw 54 is threaded through the telescopic plate 53 and extends to the outside of the telescopic plate 53. The vertically arranged limiting rod 92 is located on one side of the screw, and the bottom of the limiting rod 92 is fixedly connected to the top of the support plate 1. The top of the limiting rod 92 passes through the telescopic plate 53 and is slidably connected to the telescopic plate 53. Through the limiting action of the limiting rod 92, the abutment plate rises and falls along the axial direction of the limiting rod 92.

[0022] When workers process quilted fabrics of different sizes, they adjust the positions of the two second slide rails 22 via the drive block 14 and drive rod 13, causing the two second slide rails 22 to move along the length of the support plate 1 until they reach the set position. This causes the two first sliders 31 located at the ends of the two second slide rails 22 to move synchronously. When the positions of the two first sliders 31 change, the elastic potential energy of the spring 42 is transmitted, and several second sliders 32 move synchronously within the first slide rail 21 and the second slide rail 22. This makes the first sliders 31 and the second sliders 32 evenly distributed along the length of the support plate 1, thereby causing the clamping clamp 11 to move synchronously and evenly clamp the quilted fabric. At this time, the operator adjusts the abutment screw 54. The rotation of the abutment screw 54 drives the telescopic plate 53 to rise and fall, thereby driving the abutment rod 52 to rise and fall synchronously. The abutment spring 51 is compressed. Through the elastic potential energy of the abutment spring 51, it abuts against the first slider 31 and the second slider 32, making the first slider 31 and the second slider 32 less likely to move at will, thereby improving the stability of the first slider 31 and the second slider 32, and further improving the stability of the clamping clamp 11. This makes it less likely for the clamping clamp 11 to move at will when processing quilted fabric. At the same time, when processing quilted fabric of different sizes, the position of the clamping clamp 11 can be adjusted to adapt to different sizes of quilted fabric, thus expanding the range of applications. Moreover, the position of the quilted fabric does not need to be manually adjusted by the operator, reducing manual intervention, thereby reducing operational errors and improving production efficiency.

[0023] Each support groove 12 has two horizontally formed limiting grooves 15 on its sidewall, located on opposite sides of the support plate 1. Each limiting groove 15 is connected to the support groove 12. A drive groove 16 is horizontally formed on the sidewall of each support groove 12, located in the middle of the support plate 1 and connected to the support groove 12. Each support groove 12 contains a drive mechanism 6, a limiting component 72, a rotating component 8, and a cross plate 17. The drive mechanism 6 includes a rotating shaft 61, a drive screw 62, and a screw sleeve 63. The limiting component 72 includes a limiting block. The rotating component 8 includes a rotating motor 81, a driving wheel 82, and a driven wheel 83.

[0024] A horizontally positioned rotating shaft 61 is located within the support groove 12 and is rotatably connected to the side wall of the support groove 12. There are two horizontally positioned driving screws 62, which are located at both ends of the rotating shaft 61. Each driving screw 62 is coaxially and fixedly connected to the end of the rotating shaft 61. There are two horizontally positioned threaded sleeves 63, which are located at both ends of the driving screws 62. The inner side wall of each threaded sleeve 63 is threadedly connected to the driving screw 62, and the outer side wall of each threaded sleeve 63 is rotatably connected to the side wall of the support groove 12. The end of each threaded sleeve 63 is coaxially and fixedly connected to the side of the driving rod 13 away from the driving block 14. There are two horizontally positioned limit blocks, each corresponding to one of the two threaded sleeves 63. One side of each limit block is fixedly connected to the side wall of the threaded sleeve 63, and the other side of each limit block extends into the limit groove 15 and is slidably connected to the side wall of the limit groove 15. Each limit block has a ball bearing 73 installed on its side wall. One side of the ball bearing 73 is rotatably connected to the side wall of the limit block, and the other side of the ball bearing 73 contacts the side wall of the limit groove 15, thereby reducing wear between the limit block and the limit groove 15 and extending the service life of the limit block.

[0025] A horizontally arranged transverse plate 17 is located on the side wall of the drive groove 16 and is fixedly connected to the side wall of the drive groove 16. The transverse plate 17 is located on one side of the rotating shaft 61. A horizontally arranged driving wheel 82 is sleeved on the rotating shaft 61 and is fixedly connected to the rotating shaft 61 coaxially. A horizontally arranged driven wheel 83 is located on one side of the driving wheel 82 and is meshed with the driving wheel 82. The side wall of the driven wheel 83 is rotatably connected to the side wall of the transverse plate 17. A rotating motor 81 is located on the transverse plate 17 and is fixedly connected to the transverse plate 17. The output shaft of the rotating motor 81 is fixedly connected to the driven wheel 83 coaxially. Each support plate 1 has a baffle 91 installed at its end. The horizontally arranged baffle 91 is located on one side of the threaded sleeve 63. Each baffle 91 is detachably connected to the side wall of the support plate 1 by bolts. Each baffle 91 is used to abut against the limiting block, so that the limiting block is not easily disengaged from the limiting groove 15.

[0026] When processing quilted fabrics of different sizes, the operator adjusts the rotating motor 81. The output shaft of the rotating motor 81 rotates, causing the driven wheel 83 to rotate synchronously, which in turn drives the driving wheel 82 to rotate synchronously. The rotation of the driving wheel 82 drives the rotating shaft 61 to rotate synchronously, which in turn drives the two screws to rotate synchronously. Through the limiting block and the limiting groove 15, the two screw sleeves 63 move in a direction that approaches or moves away from each other, thereby driving the drive rod 13 and the drive block 14 to move synchronously, which in turn drives the two second slide rails 22 to move synchronously, thereby adjusting the position of the two second slide rails 22, and then adjusting the position of the two first sliders 31 and several second sliders 32, thereby synchronously adjusting the position of the clamping clamp 11. This adapts to quilted fabrics of different sizes, reduces manual intervention by the operator, thereby reducing operational errors and improving production efficiency.

[0027] The working principle of this utility model is as follows: In this embodiment, when the quilting machine frame is in use, and the operator is processing quilted fabrics of different sizes, the operator starts the lower rotating motor 81. The output shaft of the rotating motor 81 rotates, driving the driven wheel 83 to rotate synchronously. Through the engagement of the driving wheel 82 and the driven wheel 83, the driving wheel 82 rotates synchronously, thereby driving the rotating shaft 61 to rotate synchronously. The rotation of the rotating shaft 61 drives the two driving screws 62 to rotate synchronously, thereby causing the two threaded sleeves 63 to move synchronously. Through the limiting block and the limiting groove 15, the two threaded sleeves 63 move in a direction away from or close to each other, thereby driving the driving rod 13 and the driving block 14 to move synchronously. The movement of the two driving blocks 14 drives the two second slide rails 22 to move synchronously in a direction away from or close to each other, thereby driving the two first sliders 31 on the ends of the two second slide rails 22 to move synchronously, thereby adjusting the position of the two first sliders 31. When the position of the two first sliders 31 changes, through the elastic potential energy of several transmission springs 42, several second sliders 32 move synchronously within the second slide rail 22 or the first slide rail 21. Until the two first sliders 31 and several second sliders 32 are evenly distributed along the length of the support plate 1, thereby driving several clamping clamps 11 to move synchronously, so that the clamping clamps 11 evenly clamp the quilted fabric. At this time, the first sliders 31 and second sliders 32 are transferred to the set position. The operator then adjusts the abutting screw 54, so that the abutting screw 54 rotates and drives the telescopic plate 53 to move synchronously. Through the limiting rod 92, the telescopic plate 53 moves in the vertical downward direction until the bottom of the telescopic plate 53 is in contact with the abutting rod 52. The top abuts against the spring 51, and through the elastic potential energy of the spring, the two first sliders 31 and several second sliders 32 are abutted and limited, making it difficult for the two first sliders 31 and several second sliders 32 to move freely. This, in turn, makes it difficult for the clamping clip 11 to move freely, improving the stability of the clamping clip 11. The position of the clamping clip 11 can be adjusted to adapt to quilted fabrics of different sizes. At the same time, there is no need for workers to manually adjust the position of the quilted fabric, reducing operational errors caused by manual intervention and improving production efficiency.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
