Description

Technical Field

[0001] This utility model relates to the field of garment production equipment technology, and specifically to a drive mechanism for a pattern making machine. Background Technology

[0002] Existing pattern making machines are mostly small-scale devices. For example, Chinese invention patent application CN118308837A discloses a fully automatic pattern making machine with a follow-up presser foot structure, including a support platform, a sewing module, an X-axis drive module, a template drive module, and a sewing template. The sewing module further includes a follow-up presser foot mechanism and a material pressing mechanism. This fully automatic pattern making machine is not suitable for the production of larger products, and the operation of the sewing template is not smooth enough.

[0003] Therefore, based on the aforementioned shortcomings of existing pattern making machines, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a drive mechanism for a pattern sewing machine to address the shortcomings of existing technologies. This pattern sewing machine solves the defects of existing pattern sewing machines, such as unstable operation of the sewing template.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A drive mechanism for a pattern making machine includes a frame, a drive motor mounted on the upper rear end of the frame, the drive motor driving a gear set, the gear set coaxially connected to a transmission shaft, the transmission shaft driving a Y-axis belt, the Y-axis belt mounted on a Y-axis module, the Y-axis belt driving a side drive arm, the side drive arm connected to a front drive arm, and the front drive arm having an upper frame and a lower frame fixed to it.

[0007] Furthermore, the drive shaft has Y-belts driving both ends, and two Y-modules are located on both sides of the headstock and mounted on the frame. The use of two Y-belts, two side drive arms, and two Y-modules increases stability.

[0008] Furthermore, the top of the Y-axis module has an upper slide rail, on which a slider is mounted. The Y-axis module is hollow, with the upper part of the Y-axis belt located above the slider and the lower part located inside the Y-axis module. The Y-axis belt rotates cyclically around the Y-axis module.

[0009] Furthermore, the Y-axis belt has teeth, and the upper end face of the slider is formed with positioning teeth. The teeth of the Y-axis belt mesh with the positioning teeth of the slider. The slider is driven to move along the upper slide rail by the Y-axis belt.

[0010] Furthermore, the front end of the Y-axis module is embedded with an adjustment rail, on which a front belt seat is fixed. The position of the front belt seat can be adjusted by moving the adjustment rail.

[0011] Furthermore, a rear belt seat is installed at the rear end of the Y-axis module, through which the drive shaft passes. The front and rear belt seats respectively fix the Y-axis belt. The Y-axis belt is parallel to the Y-axis module.

[0012] Furthermore, a connecting seat is fixedly installed on the upper end of the slider, and the connecting seat is fixedly connected to the side drive arm. The slider is driven to move by the Y-axis belt, so that the slider and the connecting seat move together, realizing the Y-axis movement of the side drive arm.

[0013] Furthermore, the bottom of the connecting seat has a slot for the Y-axis belt to pass through. The connecting seat and the slider clamp the Y-axis belt.

[0014] The beneficial effects of this utility model are as follows: the drive motor drives the gear set to rotate, the gear set drives the transmission shaft to rotate coaxially, the transmission shaft drives the Y-axis belt to rotate in the Y direction, the Y-axis belt drives the side drive arm to move in the Y direction, the side drive arm drives the front drive arm to move, so that the upper frame and lower frame of the front drive arm are fixed to the fabric to move, and the sewing pattern is performed. The overall movement is more stable and more suitable for the production of large-sized patterns. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] See Figure 1 —— Figure 6 This utility model of a pattern sewing machine includes: a frame 1, with a sewing head mounted on the upper center of the frame 1. The sewing head includes an upper sewing head base 2 and a lower sewing head base 3. A sewing head motor 7 is connected to the rear of the upper sewing head base 2, and the sewing head motor 7 drives the sewing needles of the sewing head to sew patterns. The bottom rear end of the upper sewing head base 2 is fixedly connected to the top rear end of the lower sewing head base 3. Multiple side protrusions 4 are formed on the side of the bottom end of the lower sewing head base 3. The side protrusions 4 have mounting holes, and bolts pass through the mounting holes of the side protrusions 4 to connect and fix the frame 1, so that the frame 1 and the sewing head are fixedly assembled.

[0025] The lower headstock 3 of this invention has a side mounting portion 5 for connecting a side support plate. A rear cover plate 9 is installed at the upper rear end of the frame 1, and a side protrusion 6 is formed on the top side of the rear end of the lower headstock 3. The rear cover plate 9 is fixedly connected to the side protrusion 6. A platform 8 is installed at the upper front end of the frame 1, and the side support plate supports the middle of the platform 8.

[0026] The frame 1 of this invention has a drive motor 10 mounted on its upper rear end. The drive motor 10 drives a gear set 11, which is coaxially connected to a transmission shaft 12. Both ends of the transmission shaft 12 drive Y-axis belts 13, which are mounted on a Y-axis module 14. Two Y-axis modules 14 are located on both sides of the headstock and mounted on the frame 1. The top of the Y-axis module 14 has an upper slide rail 15, on which a slider 16 is mounted. The Y-axis module 14 is hollow. The upper part of the Y-axis belt 13 is above the slider 16, and the lower part is inside the Y-axis module 14. The Y-axis belt 13 has teeth, and the upper end face of the slider 16 has positioning teeth 17. The teeth of the Y-axis belt 13 mesh with the positioning teeth of the slider 16. The front end of the Y-axis module 14 is embedded with an adjustment rail 18, and a front belt seat 19 is fixed on the adjustment rail 18. A rear belt seat 20 is installed at the rear end of the Y-axis module 14, and the drive shaft 12 passes through the rear belt seat 20. The front belt seat 19 and the rear belt seat 20 are used to fix the Y-axis belt 13.

[0027] The upper end of the slider 16 of this invention is fixedly mounted with a connecting seat 30. The bottom of the connecting seat 30 has a slot for the Y-direction belt 13 to pass through. The connecting seat 30 is fixedly connected to the side drive arms 21. A front drive arm 22 is mounted on the front part of the two side drive arms 21. The front drive arm 22 is arranged along the X direction and perpendicular to the Y-direction belt 13. A limit strip 23 is installed on the bottom surface of the upper head seat 2. The limit strip 23 is installed along the Y direction. A connecting plate 24 is installed on the upper middle part of the front drive arm 22. The connecting plate 24 has a limit groove, and the limit strip 23 is embedded in the limit groove. When the front drive arm 22 moves along the Y direction with the side drive arms 21, the stability of the front drive arm 22 can be ensured by the cooperation of the connecting plate 24 and the limit strip 23.

[0028] The front drive arm 22 of this utility model is equipped with an X-direction belt 29 and an X-direction slide rail. A movable block is mounted on the X-direction slide rail, connecting the X-direction belt 29 and a movable plate.

[0029] An X-axis motor 28 is fixed to one side drive arm 21 of this invention. The X-axis motor 28 drives the X-axis belt 29 through a drive shaft. The X-axis motor 28 drives the X-axis belt 29 to rotate, which drives the moving block to move in the X direction along the X-axis slide rail within the front drive arm 22. At the same time, the moving block plate drives the lower frame 25 and the upper frame 27 to move, thereby realizing the X-axis movement of the fabric to sew patterns.
