Description

Technical Field

[0001] The invention relates to the field of clothing processing, in particular to a cloth hot edge binding machine. Background Art

[0002] The fabric hemming machine is a mechanical equipment specially used for fabric hemming and bonding. When working, the fabric hemming machine dissolves the heating strip on the fabric through the upper and lower pressure rollers, and then presses the rollers to achieve the bonding of the fabric; it is conducive to the rapid hemming and bonding of the fabric.

[0003] Compared with the traditional needlework process, the fabric hemming machine has a simple process, and the clothes after hemming and bonding are smoother, which is conducive to improving the beauty of the clothes. At the same time, it also reduces dust and noise during production, which is conducive to improving the environmental protection of the equipment.

[0004] Existing hemming machines do not heat the hot melt adhesive hemming strips sufficiently and do not fully heat all surfaces, resulting in poor hemming effects. Summary of the invention

[0005] In order to fully heat the hemming strips and improve the hemming effect, the present application provides a fabric hot hemming machine.

[0006] The present application provides a fabric hot hemming machine that adopts the following technical solution:

[0007] A cloth hot hemming machine comprises a frame, an upper pressing roller, a lower pressing roller and a heating assembly; the upper pressing roller and the lower pressing roller are both rotatably mounted on the frame, and a working chamber for pressing and fitting the cloth with an hemming strip is formed between the upper pressing roller and the lower pressing roller; the heating assembly comprises a heating block, a heat-conducting wire and a first hot air pipe; the heating block is mounted on the frame and is used to heat the heat-conducting wire and the air blowing in the first hot air pipe, and the heat-conducting wire is mounted on the frame and is used to heat the upper pressing roller; the first hot air pipe is mounted on the frame, and the output end of the first hot air pipe is directly opposite to the hemming strip located at the input end of the working chamber.

[0008] By adopting the above technical solution, when working, the worker first wraps the edge on the cloth, and then puts the cloth and the edge strip into the working chamber together, starts the heating block and transfers the heat to the upper pressing roller through the electric heating wire, so as to heat the edge strip that is close to the upper pressing roller; at the same time, the first hot air duct blows hot air to the edge strip to preheat the edge strip that is not in contact with the cloth; under the dual heating action of the first hot air duct and the heated upper pressing roller, the edge strip is fully heated, so that the hot melt adhesive inside is fully melted and pressed against the cloth under the joint action of the upper and lower pressing rollers, thereby improving the effect of cloth edge wrapping.

[0009] Preferably, the hemming machine also includes a stabilizing frame installed on the frame, and a first fixing sleeve is provided at one end of the stabilizing frame close to the working chamber, and a first fixed chamber for the hemming rubber strip to pass through is formed between the first fixing sleeve and the stabilizing frame; a second fixing sleeve is provided at one end of the stabilizing frame away from the working chamber, and a second fixed chamber for the hemming rubber strip to pass through is formed between the second fixing sleeve and the stabilizing frame.

[0010] By adopting the above technical solution, after the edge binding strip passes through the first fixed cavity and the second fixed cavity, the edge binding strip can be stably moved and transmitted to the working cavity at the input end of the working cavity through the fixation of the two fixed cavities, thereby improving the stability and accuracy of the edge binding strip being attached to the cloth.

[0011] Preferably, the output end of the first hot air pipe faces the first fixing sleeve.

[0012] By adopting the above technical solution, the first fixing sleeve can position the edge-binding rubber strip, so that the first hot air duct can stably heat the edge-binding rubber strip.

[0013] Preferably, the rack is installed with a second hot air pipe, and the output end of the second hot air pipe is directly opposite to the second fixing sleeve.

[0014] By adopting the above technical solution, the second hot air duct is used to preheat the end of the edge strip away from the working chamber, further accelerating the melting speed of the hot melt adhesive in the edge strip, so that the edge strip can fully fit the fabric.

[0015] Preferably, the first fixing sleeve and the stabilizing frame are provided with a turning opening for allowing one end of the edging rubber strip passing through the first fixing cavity to bend toward the working cavity.

[0016] By adopting the above technical solution, after the edging strip passes through the first fixed cavity, it is bent at the turning point. At the same time, after bending at the turning point, the edging strip changes from normal extension to bending from both sides to the middle. At this time, the worker puts the cloth into the edging to form a wrapping of the cloth.

[0017] Preferably, the upper pressing roller is slidably mounted on the frame in a direction approaching or moving away from the lower pressing roller, and a driving assembly for driving the upper pressing roller to rotate on the frame is mounted on the frame.

[0018] By adopting the above technical solution, after the upper pressing roller rotates, the size of the working chamber formed between the upper pressing roller and the lower pressing roller changes. First, the larger working chamber makes it easier for workers to place the hemming strips and cloth into the working chamber, reducing the workers' adjustments to the placement of the cloth and speeding up the operation. Second, through the adjustable working chamber, it can operate on cloths of various thicknesses, thereby improving the adaptability of the hot hemming machine to different cloths.

[0019] Preferably, the driving assembly includes a swing frame and a cylinder, the upper pressure roller is rotatably mounted on the swing frame, and the swing frame is swingably mounted on the frame; the cylinder is rotatably mounted on the frame, and the piston rod of the cylinder is rotatably mounted on one end of the swing frame away from the rotating connection.

[0020] By adopting the above technical solution, the cylinder is started. When the piston rod of the cylinder is extended or retracted, the swing frame connected to the piston rod of the cylinder is swung on the frame accordingly. The position of the swing frame is adjusted to change the size of the working chamber. The use of the cylinder can accurately adjust the swing distance of the swing frame, thereby facilitating workers to operate according to fabrics of different material thicknesses.

[0021] Preferably, a driving motor is fixedly mounted on the frame, a belt is arranged on the output shaft of the driving motor, and the belt is wound around the output shaft and the rotating shaft of the lower pressure roller at the same time.

[0022] By adopting the above technical solution, a driving motor is used to actively drive the lower pressure roller to rotate, and then during operation, the rotation of the lower pressure roller drives the edge binding strip wrapped on the cloth to move, thereby improving the degree of automation of the edge binding operation.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Under the dual heating action of the first hot air duct and the heated upper pressing roller, the edge binding strip is fully heated, so that the hot melt adhesive inside is fully melted and pressed tightly on the fabric under the joint action of the upper and lower pressing rollers, thereby improving the fabric edge binding effect;

[0025] 2. After the edge tape passes through the first fixing cavity and the second fixing cavity, the edge tape can be stably moved and transmitted to the working cavity at the input end of the working cavity through the fixation of the two fixing cavities, thereby improving the stability and accuracy of the edge tape being attached to the fabric;

[0026] 3. After the upper pressing roller rotates, the size of the working chamber formed between the upper pressing roller and the lower pressing roller changes. First, the larger working chamber makes it easier for workers to put the hemming strips and fabrics into the working chamber, reducing the workers' adjustment of the fabric placement and speeding up the operation. Second, through the adjustable working chamber, it can operate on fabrics of various thicknesses, improving the adaptability of the hot hemming machine to different fabrics.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a cloth heat hemming machine. Figure 1 and Figure 2 The hot hemming machine includes a frame 1, an upper pressing roller 2, a lower pressing roller 3 and a heating assembly 4; the upper pressing roller 2 and the lower pressing roller 3 are both rotatably mounted on the frame 1, and a working chamber for pressing and fitting the fabric after the hemming strip is formed between the upper pressing roller 2 and the lower pressing roller 3; the heating assembly 4 includes a heating block 41, a heat-conducting wire 42 and a first hot air pipe 43; the heating block 41 is mounted on the frame 1 and is used to heat the heat-conducting wire 42 and the air in the first hot air pipe 43, and the heat-conducting wire 42 is mounted on the frame 1 and is used to heat the upper pressing roller 2; the first hot air pipe 43 is mounted on the frame 1, and the output end of the first hot air pipe 43 is directly opposite to the output end of the first hot air pipe 43. For the hemming strip located at the input end of the working chamber, the worker wraps the hemming strip on the cloth, and then puts the cloth and the hemming strip together in the working chamber. After starting the hot hemming machine, the air in the first hot air duct 43 is heated under the action of the heating block, thereby outputting hot air to heat the hemming strip, so that the hot melt adhesive in the hemming strip is softened. When passing through the working chamber, the upper pressing roller 2 and the lower pressing roller 3, which are heated by transferring heat through the heat conducting wire 42, work together to perform secondary heating on the hemming strip and extrude it to the edge, so that the hot melt adhesive in the hemming strip is completely melted, thereby making the hemming strip tightly attached to the cloth.

[0035] Reference Figure 2 and Figure 3The upper pressing roller 2 is slidably mounted on the frame 1 in a direction close to or away from the lower pressing roller 3, and a driving assembly 5 for driving the upper pressing roller 2 to rotate on the frame 1 is mounted on the frame 1.

[0040] The implementation principle of a hot edge binding machine for fabric in the embodiment of the present application is as follows: a worker sequentially passes the prepared edge binding strip through the second fixed cavity and the first fixed cavity 62, and under the action of the turning mouth, the two sides of the edge binding strip are closed toward the center to form a folding mouth for the fabric to be placed in; after the fabric is placed in the edge binding strip, the two are placed in the working cavity as a whole, and at the same time, the cylinder 52 is started to drive the swing frame 51 to swing on the frame 1 so that the upper pressing roller 2 and the lower pressing roller 3 work together to press the edge binding strip and the fabric; then the driving motor 11 is started to drive the lower pressing roller 3 to rotate and then drive the edge binding strip and the fabric to be transported in the working cavity to complete the hot pressing molding of the edge binding strip;

[0041] At the same time, under the action of the heating component 4, the edge adhesive strip can be preheated to soften the hot melt adhesive, and then the hot melt adhesive is melted through the overall heating of the swing frame 51.
