Description

Technical Field

[0001] The invention belongs to the technical field of clothing, and in particular relates to a heating pack and a seamless folding machine with the heating pack. Background Art

[0002] The cut pieces of cloth (cut pieces) need to be sewn together to make a garment or pants. The traditional method is to use an ordinary sewing machine to sew, which can achieve a great sewing effect, but the lines can be clearly seen at the seams, which cannot meet the needs of underwear with high requirements on fabrics.

[0003] For this purpose, a seamless gluing method has emerged, such as hot-melt adhesive film pasting and sewing, in which a hot-melt adhesive film is pasted on the cut edge of the cloth by machine or manually to achieve the purpose of seamlessness at the cut edge. The seamless process is roughly divided into two steps. First, the hot-melt adhesive film is pasted on the cut piece (gluing), and then two or more glued cut pieces are bonded together. At present, manual gluing is prone to wrinkles. In addition, after gluing, the excess cloth pieces must be manually trimmed, which is inefficient.

[0004] In order to solve the above technical problems, a Chinese utility model patent "Multifunctional Glue Laminating Device" with patent number ZL201220565623.X (authorization announcement number CN202958960U) discloses a multifunctional glue laminating device including a frame, an upper rubber wheel, and a lower rubber wheel. The upper rubber wheel and the lower rubber wheel are located at corresponding positions. The frame and the connecting arm are movably connected, and the upper rubber wheel is arranged on the outer side of the free end of the connecting arm. In the utility model multifunctional glue laminating device, the upper rubber wheel is arranged on the outer side of the free end of the connecting arm. The above-mentioned gluing device realizes seamless bonding of the cloth, but the position of the glue strip on the cloth is prone to left and right deviation, which results in the two pieces of cloth not being able to be bonded at the joint position and causes poor bonding effect. In addition, the heating structure of the blowing heating furnace and the blowing nozzle insulation block is adopted. When working, the hot air blown out by the blowing heating furnace reaches the blowing nozzle insulation block for insulation and is blown out through the blowing nozzle to soften the hot melt adhesive. The whole heating structure is complicated, which increases the complexity of the pipeline connection between the blowing nozzle insulation block and the blowing heating furnace. In addition, the air flow process is prone to generate noise.

[0005] Therefore, it is necessary to further improve the existing seamless folding machine. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a heating pack with a simple structure and reduced pipeline connections in view of the current status of the above-mentioned prior art.

[0007] The second technical problem to be solved by the present invention is to provide a seamless folding machine having the above-mentioned heating pack.

[0008] The third technical problem to be solved by the present invention is to provide a seamless folding machine with a fixed position of the adhesive strip to achieve the purpose of accurate bonding.

[0009] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a heating pack, characterized in that it includes:

[0010] A housing having at least one air inlet channel and at least one air outlet channel, wherein the air inlet channel and the air outlet channel are fluidically connected to form a flow channel;

[0011] a sound-absorbing member disposed in the housing; and

[0012] The heating element is arranged in the shell and is used to heat the airflow in the flow channel.

[0013] Preferably, there are two air inlet channels, which are arranged on the same side, and the flow passages between the air inlet channels and the air outlet channels are connected, and the heating element is located between the two air inlet channels. In this way, sufficient air outlet volume can be ensured.

[0014] In order to heat the airflow in the two air inlet channels, a plurality of through holes extending along the length direction of the air inlet channels are provided in the shell, each of the through holes is located between the two air inlet channels, and the heating element is provided in each of the through holes.

[0015] In order to reduce noise, a silencer channel extending along the extension direction of the through hole is provided in the housing, the silencer channel is connected to the flow channel, and the silencer is located in the silencer channel. In this way, when the airflow flows and collides in the flow channel, noise is easily generated. The existence of the silencer channel and the silencer can reduce noise and achieve a silencer effect.

[0016] In order to achieve the purpose of noise reduction, the silencer channels are arranged in rows, and there are at least two rows arranged along the side-by-side direction of the air intake channels. The through holes are located between two adjacent rows of silencer channels, and there are multiple through holes in each row and arranged at intervals along the side-by-side direction of the through holes.

[0017] There are many structural forms of the silencer, but preferably, each of the silencer channels is provided with a silencer, and the silencer includes at least two silencers, and a spring is provided between two adjacent silencers. The presence of the spring prevents the silencers from colliding with each other, which prevents the silencers from being damaged due to collision, and can adjust the silencer position according to the size of the airflow.

[0018] The technical solution adopted by the present invention to solve the above second technical problem is: a seamless folding machine with the above heating pack, characterized in that it also includes

[0019] a workbench on which a connecting arm is disposed;

[0020] an upper roller, rotatably disposed on the connecting arm; and

[0021] The lower roller is arranged to be rotatable relative to the workbench and is located below the upper roller and is consistent with the rotation axis of the upper roller. A gap is left between the lower roller and the upper roller for the cloth to pass through; the outlet of the outlet channel of the heating pack faces the gap.

[0022] In order to adjust the position of the heating pack according to the position of the gap, the heating pack can move back and forth along the rotation axis direction of the upper roller under the drive of the third driving mechanism, and the output end of the third driving mechanism is connected to the heating pack. In this way, the position of the heating pack can be adjusted, and when heating is not required, the heating pack is prevented from interfering.

[0023] The technical solution adopted by the present invention to solve the third technical problem is: a limiting space for partially limiting the rubber strip is provided on the connecting arm above the upper roller, and the limiting space is located above the supporting surface.

[0024] Preferably, a guide plate is provided on the workbench, and the guide plate has a support surface for placing the cloth, and along the advancing direction of the cloth, the support surface is located upstream of the gap and gradually tilts upward along the advancing direction of the cloth. In this way, it can better meet ergonomics and facilitate the placement and guidance of the cloth.

[0025] Compared with the prior art, the advantages of the present invention are that a flow channel, a heating element and a silencer are provided in the heating pack. The heating element can heat the airflow in the flow channel, so that the airflow flowing out through the air outlet channel is a hot airflow, which is convenient for heating the rubber strips of the subsequent seamless folding machine. The silencer can achieve the purpose of noise reduction and prevent the heating pack from making too much noise and affecting the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
