Description

Technical Field

[0001] This utility model relates to the field of dot sewing technology, and in particular to a dot sewing machine for the side of a mattress. Background Technology

[0002] With the development of technology, there are now more advanced automated mattress dotting production line systems available. These systems have abandoned the traditional glue bonding method and adopted an automated dotting process that can penetrate the mattress with a single needle without glue. The dots are even, beautiful, and highly efficient. These systems usually integrate functions such as automatic cutting and trimming, which further improves production efficiency and product quality.

[0003] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the fabric, allowing one or more layers of fabric to interweave or sew together. Sewing machines can sew products made of cotton, linen, silk, wool, synthetic fibers, leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing is fast and easy to use, and it has given rise to art forms such as hand-pushed embroidery and computer embroidery. For side dot stitching, a mattress side dot stitching machine may be required.

[0004] In existing technical solutions, when it is necessary to stitch the sides of a mattress, multiple materials for the sides of the mattress are usually stacked up and then stitched at specific points using a sewing machine. Finally, the mattress is rolled up using a roller. However, when rolling up, the mattress made of multiple stacked materials becomes too large, which not only affects the storage and packaging work, but also affects the subsequent transportation work.

[0005] Therefore, a mattress side dot sewing machine is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution:

[0028] A mattress side-dotting sewing machine includes a frame 1. A machine compartment 11 is fixedly connected to the upper end of the frame 1. A sewing machine assembly 2 is installed inside the machine compartment 11. A feed inlet 111 and a feed rack 21 are fixedly connected to the right end of the machine compartment 11, with the feed rack 21 located to the right of the feed inlet 111. A tensioning assembly 3 is installed at the left end of the frame 1. The tensioning assembly 3 includes a support frame 31 fixedly connected to the left end of the machine compartment 11. The upper end of the support frame 31 is fixedly connected to both its front and rear ends with fixed fasteners. A fixed plate 311 is provided, and a scroll 32 is movably connected between the two fixed plates 311. A first motor 322 is fixedly connected to the rear end of the rear fixed plate 311. The output shaft of the first motor 322 is fixedly connected to the scroll 32. A missing gear 323 is fixedly connected to the front end of the scroll 32. A round shaft 33 is movably connected inside the front fixed plate 311. A connecting rod 34 is fixedly connected to the outside of the round shaft 33. A clamping block 341 is fixedly connected to the end of the connecting rod 34 away from the round shaft 33.

[0029] The scroll 32 is externally fixedly connected to a clamping rod 321. Both of the two circular shafts 33 are movably connected to the inside of the fixed disk 311 by torsion springs 332. There are two circular shafts 33. The missing gear 323 meshes with the two adjacent driven gears 331. The elastic force of the torsion spring 332 is greater than the sum of the weights of the circular shafts 33, the connecting rods 34, and the clamping blocks 341. The swing range of the two connecting rods 34 is 0 to 90 degrees. The two clamping blocks 341 can mesh.

[0030] By adopting the above technical solution, the support frame 31 and the feeding rack 21 are first placed on the left and right sides of the machine compartment 11. Then, the mattress side assembly materials need to be installed on the feeding rack 21 respectively. Then, the assembly is installed into the machine compartment 11 through the feed port 111. The sewing machine unit 2 inside the machine compartment 11 at the upper end of the frame 1 is started to sew the mattress side materials. The sewn mattress side is then connected to the outside of the roller 32 through the machine compartment 11, and one end of the mattress side is clamped and fixed by the clamping rod 321. At this time, the first motor 322 at the rear end of the roller 32 is started. The output shaft of the first motor 322 drives the roller 32 between the two fixed disks 311 to rotate together. As the roller 32 rotates continuously, it rolls up the mattress side. At this time, the roller 32 drives the missing gear 323 to rotate. The rotation causes the driven gear 331 to mesh and rotate, while the upper driven gear 331 meshes with and causes the lower driven gear 331 to rotate. The rotation of the two driven gears 331 causes the round shaft 33, the external connecting rod 34, and the two clamping blocks 341 to swing together and clamp the side of the mattress. At this time, as the roller 32 rotates, the side of the mattress is continuously tightened. When the driven gear 331 contacts the toothless area of ​​the missing gear 323, the two torsion springs 332 separate the two connecting rods 34 and swing them apart, so that the two connecting rods 34 return to their initial positions. At this time, the roller 32 rotates to roll up the side of the mattress. This achieves the purpose of tightening the mattress roll by clamping the subsequent mattress after rolling up a section of the mattress, thereby facilitating the storage and transportation of the product.

[0031] Specifically, such as Figure 4 As shown, a material spreading assembly 4 is provided at the left end of the cabin 11. The material spreading assembly 4 includes a material discharge block 41 fixedly connected to the left end of the cabin 11. A first rotating shaft 42 is movably connected inside the material discharge block 41. There are two first rotating shafts 42. A second motor 421 is fixedly connected to the right end of the material discharge block 41. The output shaft of the second motor 421 is fixedly connected to the upper first rotating shaft 42. A pressure roller 422 is fixedly connected to the outside of the first rotating shaft 42. A first bevel gear 423 is fixedly connected to both the front and rear ends of the upper pressure roller 422. A pad block is fixed to the right end of the material discharge block 41. 411, the material spreading assembly 4 further includes a second rotating shaft 43 movably connected to the right end of the inside of the material dispensing block 41. There are two second rotating shafts 43. A second bevel gear 431 and a swing wheel 432 are fixedly connected to the outside of the second rotating shaft 43. The swing wheel 432 is located at the right end of the second bevel gear 431. The first bevel gear 423 and the second bevel gear 431 mesh with each other. The gap between the two pressure rollers 422 is less than the thickness of the mattress side. The two swing wheels 432 are located on the front and rear sides of the pad block 411 respectively. Both swing wheels 432 are in contact with the pad block 411.

[0032] By adopting the above technical solution, the mattress side material is sewn by the sewing machine unit 2 inside the machine compartment 11. When the sewn mattress side passes between the two pressure rollers 422 inside the output block 41, the second motor 421 is started. The second motor 421 rotates, causing the upper first rotating shaft 42 to rotate together with the pressure rollers 422. As the pressure rollers 422 rotate continuously, the mattress side is output to the left end of the machine compartment 11. At this time, the first rotating shaft 42 rotates, causing the first bevel gear 423 to rotate together. The rotation of the first bevel gear 423, in turn, meshes with the two second bevel gears 431, causing the two second rotating shafts 43 to rotate. The rotation of the two second rotating shafts 43 causes the swing wheels 432 to rotate in opposite directions. When the mattress side passes the upper end of the pad block 411, the two swing wheels 432 continuously flatten and unfold the mattress side, so that the unfolding component 4 can flatten and unfold the formed mattress, thereby facilitating the subsequent rolling up of the product and improving the efficiency of the mattress side sewing work.

[0033] Working principle: First, the support frame 31 and the feeding rack 21 are placed on the left and right sides of the machine compartment 11. Then, the mattress side assembly materials need to be installed on the feeding rack 21 respectively. Then, the assembly is installed into the machine compartment 11 through the feed port 111. The sewing machine unit 2 inside the machine compartment 11 is started to sew the mattress side materials. The sewn mattress side is then connected to the outside of the roller 32 through the machine compartment 11, and one end of the mattress side is fixed by the clamping rod 321. At this time, the first motor 322 at the rear end of the roller 32 is started. The output shaft of the first motor 322 drives the roller 32 between the two fixed plates 311 to rotate together. As the roller 32 rotates continuously, it rolls up the mattress side. At this time, the roller 32 drives the missing gear 323 to rotate. The rotation of the missing gear 323 drives the mattress side to rotate. The driven gear 331 meshes and rotates, and the driven gear 331, through meshing, drives the lower driven gear 331 to rotate. The rotation of the two driven gears 331 causes the round shaft 33 and the external connecting rod 34 to swing together, clamping the side of the mattress. At this time, as the roller 32 rotates, the side of the mattress is continuously tightened. When the driven gear 331 contacts the toothless area of ​​the missing gear 323, the two torsion springs 332 respectively separate the two connecting rods 34 and swing them back to their initial positions. At this time, the roller 32 rotates to roll up the side of the mattress. This achieves the purpose of tightening the mattress roll by clamping the subsequently discharged mattress after rolling up a section of the mattress, thereby facilitating the storage and transportation of the product.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
