Abstract

This utility model discloses a tent sewing material feeding device, including a sewing machine. A connecting frame is welded to one side of the sewing machine, and an mounting frame is fixedly installed on the upper surface of the sewing machine. A material roll is installed on one side of the top of the mounting frame, and a feeding mechanism for feeding the material roll is fixed on the top of the mounting frame. The operation of the feeding mechanism controls the rotation of the material roll, realizing automatic tension control of the waterproof heat-sealing strip during feeding, ensuring the tension of the waterproof heat-sealing strip during the conveying process. A section of the tent material being sewn is squeezed and fixed between two squeezing rollers. Then, the moving frame is controlled to move, which drives the squeezing rollers to pull the tent material.

At the same time, the feeding of the tent material can be controlled by the first motor driving the friction roller to rotate, thereby improving the quality of tent sewing.

Description

Technical Field

[0001] This utility model relates to the field of tent manufacturing technology, specifically a tent sewing feeding device. Background Technology

[0002] During the tent production process, tent material is divided into several rectangles of different sizes. The edges of these rectangles are then sewn together. To ensure the seal at the seams, waterproof heat-sealing strips are applied to the joints between the two pieces of tent material. The waterproof heat-sealing strips are then sewn together with the two pieces of tent material to ensure the overall waterproof performance of the tent.

[0003] In existing technologies, when sewing two pieces of tent fabric, a roll containing waterproof heat-sealing strips is placed above the sewing equipment. The waterproof heat-sealing strips are fed simultaneously as the two pieces of tent fabric are sewn. However, the waterproof heat-sealing strips remain loose, resulting in wrinkles at the contact points between the strips and the tent fabric, affecting the sewing quality. Furthermore, while existing technologies use a clamping device to hold one end of the tent fabric in place due to its length, and control the automatic movement of the sewing position, the area to be sewn still requires manual feeding, leading to wrinkles and bending at the sewing points, again affecting the sewing quality.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a tent sewing material feeding device includes a sewing machine 1. A connecting frame 2 is welded to one side of the sewing machine 1. A mounting frame 3 is fixedly installed on the upper surface of the sewing machine 1. A material roll 4 is installed on one side of the top of the mounting frame 3. A feeding mechanism 5 for feeding the material roll 4 is fixed on the top of the mounting frame 3. A first motor 22 is fixedly installed on the upper surface of the sewing machine 1 near the sewing position. A friction roller 23 is fixedly installed on the output shaft of the first motor 22 by bolts. Tent material passes under the friction roller 23 and is in frictional contact with the friction roller 23. A movable frame 7 is slidably installed in the middle of the connecting frame 2. Squeezing rollers 8 are symmetrically installed on one side of the movable frame 7. The tent material is positioned between the two squeezing rollers 8. The edge of the tent material is fed through the friction roller 23 and conveyed to the sewing machine 1. On the sewing assembly, the waterproof heat-sealing strip on the material roll 4 is simultaneously placed above the edge of the tent material. The sewing equipment 1 performs the sewing operation on the tent material. The material roll 4 is rotated by the operation of the feeding mechanism 5 to achieve automatic tension control of the waterproof heat-sealing strip, ensuring the tension of the waterproof heat-sealing strip during the conveying process. After sewing a section of tent material, the sewn section is placed between two extrusion rollers 8. The sewn section of tent material is squeezed and fixed between the two extrusion rollers 8, and then the sewing operation is performed here. The moving frame 7 is controlled to move, which will drive the extrusion rollers 8 to pull the tent material. The sewn tent material can be moved. During the conveying process of the tent material, the friction between the friction roller 23 and the tent material will maintain the tension of the tent material between the friction roller 23 and the extrusion roller 8. At the same time, the first motor 22 drives the friction roller 23 to rotate, which can control the feeding of the tent material.

[0023] like Figures 1 to 5 As shown, the feeding mechanism 5 includes a second motor 9 and an expansion shaft 10. The second motor 9 is fixedly installed on one side of the top of the mounting frame 3. The output shaft of the second motor 9 passes through the mounting frame 3 and is fixedly installed on the expansion shaft 10 through a shaft connector. The output shaft of the second motor 9 is rotatably connected to the mounting frame 3 through a bearing. The material roll 4 is set on the outside of the expansion shaft 10.

[0024] The material roll 4 is fixed on the outside of the expansion shaft 10. The expansion shaft 10 is rotated by the second motor 9, which in turn drives the material roll 4 to rotate, thereby achieving automatic feeding of the waterproof heat-sealing strip to adjust its tightness.

[0025] like Figures 1 to 5As shown, an extension frame 11 is integrally provided in the middle of the mounting frame 3. A mounting block 12 is installed in the middle of the extension frame 11. A rotating shaft 13 is rotatably mounted in the middle of the mounting block 12 via a bearing. A guide wheel 14 is fixedly installed at the end of the rotating shaft 13. A waterproof heat-sealing strip is provided through the guide wheel 14.

[0026] When conveying the waterproof heat-sealing strip, the guide wheel 14 guides the waterproof heat-sealing strip to control the vertical conveying of the waterproof heat-sealing strip onto the sewing equipment 1.

[0027] like Figures 1 to 5 As shown, the extension frame 11 is symmetrically fixedly installed with limit rods 15 in the middle. The mounting block 12 is slidably installed between the two limit rods 15. An adjusting spring 16 is sleeved on the outer side of the limit rod 15. The bottom end of the adjusting spring 16 is fixedly connected to the bottom of the extension frame 11, and the top end of the adjusting spring 16 is fixedly connected to the lower surface of the mounting block 12.

[0028] When conveying the waterproof heat-sealing strip, the tensioned waterproof heat-sealing strip will press down on the guide wheel 14. The position of the mounting block 12 connected to the guide wheel 14 in the extension frame 11 is adjusted by the adjusting spring 16 to ensure the tension of the waterproof heat-sealing strip at all times, and to prevent the tension of the waterproof heat-sealing strip from being affected by the mismatch between the conveying speed and the sewing speed.

[0029] like Figures 1 to 5 As shown, guide rods 17 are symmetrically fixedly installed on the lower top surface of the connecting frame 2. The movable frame 7 is slidably installed between the two guide rods 17. A screw 18 is rotatably installed on the lower top surface of the connecting frame 2 at the position between the two guide rods 17 via a bearing. The screw 18 is threadedly connected to the middle of the movable frame 7. A third motor 19 is fixedly installed at one end of the connecting frame 2 at the position corresponding to the screw 18. The output shaft of the third motor 19 is fixedly connected to one end of the screw 18.

[0030] The operation of the third motor 19 drives the screw 18 to rotate. The screw 18 is connected to the moving frame 7 by a thread, which controls the moving frame 7 to move along the trajectory of the two guide rods 17, thereby driving the extrusion roller 8 to pull the tent material.

[0031] like Figures 1 to 5 As shown, the bottom squeezing roller 8 is fixedly installed on one side of the movable frame 7, the top of the movable frame 7 is fixedly installed with an electric push rod 20, the moving end of the electric push rod 20 passes through the movable frame 7 and is fixedly installed with a lifting block 21, and the top squeezing roller 8 is fixedly installed on one side of the lifting block 21.

[0032] The section of tent material sewn together is positioned between two compression rollers 8. By controlling the operation of the electric push rod 20, the moving frame 7 is lowered, and the section of tent material sewn together is pressed and fixed between the two compression rollers 8.

[0033] like Figures 1 to 5 As shown, a fixing plate 6 is welded to the upper surface of the sewing device 1 below the friction roller 23, and the friction coefficient of the surface of the fixing plate 6 is relatively small.

[0034] When the tent material is fed through the edge of the sewing position below the friction roller 23, the fixing plate 6 prevents friction damage between the tent material and the upper surface of the sewing equipment 1.

[0035] This utility model provides a tent sewing material feeding device, the specific working principle of which is as follows:

[0036] In use, the material roll 4 is fixed to the outside of the expansion shaft 10. The edge of the tent material is fed through the friction roller 23 and then conveyed to the sewing assembly of the sewing equipment 1. Simultaneously, the waterproof heat-sealing strip on the material roll 4 is placed above the edge of the tent material. The sewing equipment 1 performs the sewing operation on the tent material. The second motor 9 drives the expansion shaft 10 to rotate, which in turn drives the material roll 4 to rotate, achieving automatic tension control of the waterproof heat-sealing strip and ensuring tension during the conveying process. After sewing a section of tent material, the sewn section is placed between the two compression rollers 8. The electric push rod 20 is controlled to lower the moving frame 7, thus lowering the tent material. The material is pressed and fixed between two pressing rollers 8 at one end, and then the sewing operation is performed here. At the same time, the operation of the third motor 19 drives the screw 18 to rotate. The screw 18 is connected to the moving frame 7 by a thread, which controls the movement of the moving frame 7 along the trajectory of the two guide rods 17. This causes the pressing rollers 8 to pull the tent material, which can move the sewn tent material. During the conveying of the tent material, the friction between the friction roller 23 and the tent material will maintain the tension of the tent material between the friction roller 23 and the pressing roller 8. At the same time, the first motor 22 drives the friction roller 23 to rotate, which can control the feeding of the tent material. In addition, the worker can also tighten the tent material to manually control the tension of the tent material during the conveying.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
