Description

Technical Field

[0001] The utility model relates to the technical field of edge trimming structures, in particular to a polyester overlock edge trimming machine. Background Art

[0002] Overlocking is also called lock edge. In the process of producing clothing, since the materials used are generally synthetic fibers such as polyester, the texture is relatively hard. After cutting, the silk threads at the edge of the cut clothing will spread out due to its high hardness, so overlocking is needed: a special overlocking machine is used to overlock a circle of edges at the edge to prevent the silk threads in the fabric from spreading out. This also plays a role in aesthetics.

[0003] During the edge-locking process of polyester materials, there are usually a lot of broken scraps attached to the surface of the fabric due to electrostatic adsorption, which makes the waste easily adsorbed on the surface of the machine and human body when the fabric is pushed during the edge-locking sewing, affecting the edge-locking process of the personnel.

[0004] For this reason, we propose a polyester overlock edge trimming machine to solve the existing problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. During the use of the polyester overlocking line edge collecting machine, the polyester fabric is overlocked. During this process, the suction cup can be controlled to rest against the surface of the fabric. During the translation of the fabric, the suction cup and the fabric are in rolling contact. At this time, the air inside the suction cup is sucked through the pump body.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] like Figure 1-3As shown, the polyester overlock edge trimming machine proposed by the utility model includes a table 1, a suction cylinder 3, a sliding sleeve 6 and a box body 11. A support seat 2 is provided on the lower surface of the table body 1, a machine head 13 is provided on the upper surface of the table body 1, a sewing needle 5 is provided on the machine head 13, a pin block 7 is movably provided on the outer wall of the machine head 13, the pin block 7 is movably plugged into the sliding sleeve 6, a suction cylinder 3 is rotatably provided on the sliding sleeve 6, a suction tube 4 is rotatably provided on the suction cylinder 3, the suction tube 4 passes through the sliding sleeve 6 and is fixed on the box body 11, and the box body 11 is provided on the upper surface of the machine head 13.

[0021] Based on Example 1: The polyester fabric is overlocked by the action of the sewing needle 5 of the head 13 of the overlock machine. During this process, the suction cylinder 3 can be controlled to press against the surface of the fabric. During the translation of the fabric, the suction cylinder 3 rolls in contact with the fabric. At this time, the air inside the suction cylinder 3 is sucked by the pump body 9. Under the action of negative pressure, the suction cylinder 3 that rolls in contact with the fabric absorbs the waste material attached to the fabric and transfers it to the box body 11.

[0022] Embodiment 2

[0023] like Figure 1-3 As shown, the polyester overlock edge trimming machine proposed by the utility model, compared with the first embodiment, this embodiment also includes: the outer wall of the machine head 13 is installed with a pneumatic rod 8 by bolts, and the bottom end of the pneumatic rod 8 is fixed to the upper surface of the pin block 7 by bolts. Through the design of the pneumatic rod 8, power can be provided for the up and down movement of the suction cylinder 3.

[0024] The pin block 7 is slidably connected to the sliding sleeve 6, and a spring 14 is fixed to the bottom end of the inner wall of the sliding sleeve 6 by bolts. The other end of the spring 14 is fixed to the lower surface of the pin block 7 by bolts. Through the design of the spring 14, when the pneumatic rod 8 drives the suction cylinder 3 to move down and press against the surface of the polyester fabric, the spring 14 makes the suction cylinder 3 elastically contact with the fabric to prevent the suction cylinder 3 from pressing the fabric to a stop.

[0025] A pump body 9 is provided on the upper surface of the box body 11 by bolts, and the suction end of the pump body 9 is at the top end of the inner wall of the box body 11. A filter screen 10 is fixed to the upper end of the inner wall of the box body 11, and a drawer 12 is slidably provided at the bottom end of the inner wall of the box body 11. Through the cooperation of the above structure, the pump body 9 sucks the air inside the suction cylinder 3 through the suction pipe 4, and the adsorbed waste enters the suction cylinder 3, and then enters the box body 11 through the suction pipe 4. After being blocked by the filter screen 10, it falls into the drawer 12 under the action of gravity.

[0026] The sliding sleeve 6 is provided with a through hole matched with the suction pipe 4 , and the suction pipe 4 is movably plugged into the through hole. The installation position of the suction pipe 4 is limited by the design of the through hole.

[0027] There are four support bases 2 in total, and the positions of the four support bases 2 are distributed in a rectangular array on the lower surface of the platform 1.

[0028] It should be noted that the pneumatic rod 8, the pump body 9 and the head 13 of the overlock machine are existing mature technologies, and their working principles and internal structures are known to technicians in the relevant technical field. The present invention only utilizes its functions and does not improve its internal structure.
