A reverse seam pressing device for a garment seam pressing machine

Abstract

This utility model belongs to the field of garment production technology, specifically relating to a backstitching device for a garment seam sealing machine. It includes a connecting pipe installed on the seam sealing machine, the connecting pipe having an L-shaped structure. An air inlet pipe is connected to the vertical section of the connecting pipe, and a fixed seat is fixedly fitted onto the horizontal section of the connecting pipe. A pressure plate is fixedly connected to one side of the bottom of the fixed seat, the pressure plate having a triangular structure. When the seam sealing machine conveys the fabric, the fabric first passes under the pressure plate, and the inclined backstitching plate presses down on the protrusions at the seam seam, initially flattening them. With the conveyor rollers, the initially flattened fabric passes under the ironing plate, where it can be ironed and flattened a second time by the heated high-temperature ironing plate. This minimizes the problem of the fabric lifting up again before the waterproof tape is applied, preventing the waterproof tape from sticking tightly and affecting the waterproof performance of the seam seam.

Description

Technical Field

[0001] This utility model belongs to the field of garment production technology, and specifically relates to a backstitching device for a garment seam sealing machine. Background Technology

[0002] A garment seam sealing machine is used to press waterproof tape onto the edges of garment seams to ensure the waterproof performance of the seam. It is mainly used in the production and processing of outdoor clothing such as windbreakers and raincoats. Before pressing the tape, the fabric at the seam needs to be flattened by a backstitching device so that the tape can better adhere to the fabric.

[0003] Existing backstitching and pressing devices typically install a pressure plate directly on one side of the conveyor wheel. When the garment is transported by the conveyor wheel, the pressure plate works with the conveyor wheel to press the fabric flat. If the fabric is hard, the pressed fabric may curl up again after being transported and separated from the pressure plate, which seriously affects the subsequent application and pressing of waterproof tape. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed backstitching device for a garment seam sealing machine in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A backstitching device for a garment seam sealing machine includes a connecting pipe installed on the seam sealing machine. The connecting pipe has an L-shaped structure. An air inlet pipe is connected to the vertical section of the connecting pipe. A fixing seat is fixedly fitted on the horizontal section of the connecting pipe. A pressure plate is fixedly connected to the bottom of one side of the fixing seat. The pressure plate has a triangular structure. A backstitching plate is integrally formed on the bottom of one side of the pressure plate. The backstitching plate is perpendicular to the pressure plate. An ironing plate is fixedly connected to the bottom of the other side of the fixing seat. A heat insulation cover is fixedly connected to the upper surface of the ironing plate. An air inlet hole communicating with the inside of the connecting pipe is opened on the side of the heat insulation cover near the connecting pipe.

[0007] As a further optimization of this utility model, a top plate is fixedly connected to the top of the vertical connecting pipe, and a sliding seat is slidably sleeved on the connecting pipe below the top plate. A tension spring is sleeved on the connecting pipe between the sliding seat and the top plate, and the two ends of the tension spring are fixedly connected to the top plate and the sliding seat, respectively.

[0008] As a further optimization of this utility model, both sides of the slide extend outward to form a mounting plate. A fixing hole is provided at the end of the mounting plate away from the slide. A bolt passes through the fixing hole and is screwed and fixed to the glue pressing machine after passing through the fixing hole.

[0009] As a further optimization of this utility model, a three-way connector is installed on the connecting pipe below the slide block. One end of the air intake pipe is connected to the vertical section of the connecting pipe through the three-way connector, and the other end of the air intake pipe is connected to the exhaust end of an external hot air blower.

[0010] As a further optimization of this utility model, the ironing board is made of a material with excellent thermal conductivity, and the bottom height of the ironing board is flush with the bottom height of the seam board.

[0011] As a further optimization of this utility model, the open end of the heat insulation cover is placed on the upper surface of the ironing board and fixed to the ironing board, and an exhaust hole is provided on one side wall of the heat insulation cover.

[0012] As a further optimization of this utility model, a plug is fixedly connected to one end of the connecting pipe near the fixed base, and an anti-scalding tube is sleeved on the outer surface of the connecting pipe. Both the plug and the anti-scalding tube are made of heat-insulating material resistant to high temperature.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the sealing machine conveys the fabric, the fabric first passes under the pressure plate and is initially flattened by the inclined back seam plate pressing down on the protrusions at the seam of the fabric. As the conveyor rollers carry the fabric, the initially flattened fabric passes under the ironing plate. At this time, the fabric can be ironed and flattened a second time by the heated ironing plate, which helps to prevent the fabric from curling up again before the waterproof tape is pressed on, which would cause the waterproof tape to not adhere properly and affect the waterproof performance of the fabric seam.

[0015] 2. The plugs connected to the connecting pipe, the anti-scalding pipes fitted on the outer surface of the connecting pipe, and the heat insulation cover are made of high-temperature resistant heat insulation materials, which can minimize the problem of excessive temperature of the connecting pipe and the heat insulation cover, and prevent workers from being easily burned during operation.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1 - Figure 4 As shown, a backstitching device for a garment seam sealing machine includes an L-shaped connecting pipe 1. A slide block 3 is slidably mounted on the vertical section of the connecting pipe 1. Both sides of the slide block 3 extend outward to form mounting plates. A fixing hole 4 is provided at the end of the mounting plate away from the slide block 3. A bolt 5 passes through the fixing hole 4 and is screwed to the seam sealing machine after passing through the fixing hole 4. The screw connection method not only makes the connection stable, but also facilitates the installation and disassembly of the slide block 3.

[0024] A top plate 2 is fixedly installed at the top of the vertical section of the connecting pipe 1. The top plate 2 can seal the top of the vertical section of the connecting pipe 1. A tension spring 6 is sleeved on the connecting pipe 1 between the top plate 2 and the slide 3. The two ends of the tension spring 6 are fixed to the top plate 2 and the slide 3 respectively. When the user is backstitching and pressing the garment, he can slide the connecting pipe 1 upward to stretch the tension spring 6 and adjust the distance between the horizontal section of the connecting pipe 1 and the feed wheel. When the user releases the connecting pipe 1, the tension spring 6 can pull the connecting pipe 1 in the opposite direction under its own elastic force, and drive the connecting pipe 1 to reset.

[0025] A three-way connector 7 is installed on the connecting pipe 1 below the slide 3. One end of the air inlet pipe 8 is connected to the three-way connector 7. The air inlet pipe 8 is connected to the inside of the connecting pipe 1 through the three-way connector 7. The end of the air inlet pipe 8 away from the three-way connector 7 is connected to the exhaust end of the external hot air blower, so that when the user uses it, the hot air blower can be used in conjunction with the air inlet pipe 8 and the three-way connector 7 to deliver high-temperature gas into the connecting pipe 1.

[0026] A fixed seat 9 is fixedly connected to the horizontal section of the connecting pipe 1. A pressure plate 10 is fixedly connected to the bottom of one side of the fixed seat 9. The pressure plate 10 has a triangular structure. A reverse seam plate 11 is integrally formed on the bottom of one side of the pressure plate 10 and is perpendicular to the pressure plate 10. When the fabric is transferred between the feed wheel and the pressure plate 10, the reverse seam plate 11 can press down the protrusion at the seam position of the fabric and flatten the protrusion.

[0027] An ironing board 12 is fixedly connected to the bottom of the other side of the fixing base 9. The ironing board 12 is made of a material with excellent thermal conductivity. The bottom height of the ironing board 12 is flush with the bottom height of the seam board 11. A heat insulation cover 13 is provided above the ironing board 12. The open end of the heat insulation cover 13 covers the upper surface of the ironing board 12 and is fixed to the ironing board 12. The side of the heat insulation cover 13 near the connecting pipe 1 communicates with the inside of the connecting pipe 1 through the air inlet 14. A plug 16 is fixedly connected to the end of the connecting pipe 1 near the fixing base 9. When high-temperature gas is transmitted to the fixing base 9 along the connecting pipe 1, the plug 16 seals the gas. Due to the blocking effect, the high-temperature gas cannot be discharged from the bottom of the connecting pipe 1. Under the subsequent air pressure, the high-temperature gas passes through the air inlet 14 into the heat insulation cover 13 and is discharged from the exhaust hole 15 on one side of the heat insulation cover 13. When the high-temperature gas passes through the heat insulation cover 13, it will heat the ironing board 12. When the fabric, which has been initially flattened by the back seam board 11, passes through the ironing board 12, it can be ironed and flattened again by the high-temperature ironing board 12, so as to avoid the fabric from curling up again before pressing the waterproof tape, which would cause the waterproof tape to not be properly adhered and affect the waterproof performance of the fabric seam.

[0028] A scalding tube 17 is fitted on the outer surface of the connecting pipe 1. Both the plug 16 and the scalding tube 17 are made of high-temperature resistant heat insulation material, which can minimize the problem of the connecting pipe 1 being affected by high-temperature gas and getting too hot, which could easily burn the staff.

[0029] It should be noted that, in use, the reverse seam pressing device of this garment seam pressing machine is operated by sliding the connecting pipe 1 upward to stretch the tension spring 6, causing the bottom of the reverse seam plate 11 and the ironing plate 12 to separate from the feed wheel. Then, the fabric sewing position is placed between the feed wheel and the reverse seam plate 11. At this time, the connecting pipe 1 can be released, allowing the tension spring 6 to return the reverse seam plate 11 and the ironing plate 12 to their original positions under its own elastic force, pressing them against the fabric. Then, the operator starts the external hot air blower to deliver high-temperature gas into the connecting pipe 1 through the air inlet pipe 8. After the high-temperature gas is delivered to the heat insulation cover 13 through the connecting pipe 1, it will heat the ironing plate 12 at the bottom of the heat insulation cover 13.

[0030] When the sealing machine conveys the fabric, the fabric first passes under the pressure plate 10 and is pressed flat by the inclined backstitch plate 11, which presses down on the protrusion at the seam of the fabric. The protrusion is initially flattened. As the conveyor wheel is conveyed, the pre-flattened fabric passes under the ironing plate 12. At this time, the fabric can be ironed flat again by the heated high-temperature ironing plate 12, which avoids the fabric from curling up again before the waterproof tape is pressed on, which would cause the waterproof tape to not be properly adhered and affect the waterproof performance of the fabric seam.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
