Description

Technical Field

[0001] This utility model belongs to the technical field of sock production equipment, and specifically relates to a dustproof mechanism for a sock sewing device. Background Technology

[0002] The toe-sewing process is the final step in sock knitting. It involves sewing the toe area of ​​the finished sock together. Traditionally, this is done on a sewing machine. Modern one-piece sock knitting machines consist of two parts: a knitting unit and a toe-sewing unit. After knitting, the sock can be transferred to the toe-sewing unit for direct sewing. Existing toe-sewing units typically include a toe-sewing box and sewing and cutting components mounted on it.

[0003] For example, Chinese invention patent publication number "CN102046873B" discloses a sewing or crocheting head specifically for automatically closing a tubular knitted article at one of its axial ends, comprising: a pair of sewing pieces that can move along corresponding actuation paths and cooperate with each other to form a sewing chain stitch; and a cutting piece that can be actuated to cut the sewing chain stitch, with a support block associated with a support structure of the sewing head; in the sewing or crocheting head, the cutting piece can approach the intersection of the paths of the pair of sewing pieces or the point where the sewing chain stitch is formed and engage with the sewing chain stitch, thereby minimizing the length of the sewing chain stitch beyond the required length of the sewing or crocheting article, and thus reducing the time required for sewing or crocheting operations.

[0004] Socks are prone to generating a lot of fine lint (or hair) during sewing. This lint is scattered in the air of the sewing workshop. Since a large area of ​​the sewing thread and the sewing head box is exposed to the air, the lint in the air can easily adhere to the sewing thread or the internal structure of the sewing head box. When the sock sewing head device drives the sewing thread, the lint that falls off and the lint that adheres to the sewing thread can easily clog the internal structure of the sewing head box and the needle holes of the sewing needles, causing the sewing thread to break and affecting production efficiency.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0006] The purpose of this utility model is to provide a dustproof mechanism for a sock sewing device, which can effectively protect the sewing box of the sock sewing device, reduce the exposed area of ​​the sewing box and the sewing thread on the sewing box, and prevent lint from clogging the internal structure and needle holes of the sewing box, thus preventing the sewing thread from breaking.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] A dustproof mechanism for a sock sewing device includes a dust cover fitted onto a sewing box and a fixing side plate for fixing the dust cover. The inner side of the fixing side plate is fixed to the outer side of the sewing box. The outer side of the fixing side plate has several protruding fixing portions. The inner side wall of the dust cover has a locking portion corresponding to the position of the fixing portion, which engages with the fixing portion. The fixing portion is arranged laterally. The outer side of the fixing portion has a recess. The locking portion includes a housing. A groove is formed inside the housing for the fixing portion to be inserted. A spring is provided on the dust cover corresponding to the position of the locking portion. The position of the spring corresponds to the position of the groove. There is a gap between the outer side of the spring and the dust cover. The side of the spring facing the groove has a protrusion that engages with the recess.

[0009] Furthermore, two fixing parts are provided on the outer side of the fixed side plate, and the two fixing parts are arranged at an upper and lower interval.

[0010] Furthermore, a guide strip corresponding to the bottom of the housing is provided below one of the fixing parts, and when the bottom of the outer side of the housing abuts against the top of the guide strip, the fixing part is aligned with the inlet of the groove.

[0011] Furthermore, the fixing part is arranged in a horizontal arrow shape, and the recessed part is located in the middle of the fixing part.

[0012] Furthermore, one end of the dust cover is provided with an inlet, and the other end of the dust cover is provided with an outlet.

[0013] Furthermore, the outer side of the dust cover is also provided with a first long groove and a second long groove arranged horizontally. The first long groove and the second long groove are arranged vertically at intervals. The first long groove is arranged at the position corresponding to the torsion spring, and the second long groove is arranged at the position corresponding to the tensioner. The fixing part located below is located between the first long groove and the second long groove.

[0014] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0015] This utility model's dustproof mechanism, through the setting of a dustproof cover and a fixing side plate for fixing the dustproof cover, allows the locking part and fixing part to be aligned before the sock sewing device starts working. Then, the dustproof cover is installed on the fixing side plate. By setting mutually locking recesses and protrusions, when the fixing part is located in the groove of the locking part, the protrusion on the spring can be located in the recess of the fixing part, thereby achieving the locking effect. The dustproof cover, locked onto the sewing box, can effectively protect the sewing box, reduce the exposed area of ​​the sewing box and the sewing thread on the sewing box, and prevent airborne hair from adhering to the sewing thread on the sewing box, causing blockage of the internal structure of the sewing box and the needle hole of the sewing needle, resulting in thread breakage and affecting production efficiency.

[0016] Furthermore, the addition of guide strips allows operators to easily align the bottom of the housing with the guide strips when installing the dust cover, thus facilitating quick alignment of the slide groove with the fixing part and making installation convenient.

[0017] Furthermore, the opening of the first and second long slots facilitates installation and also saves materials, thereby reducing costs. Attached Figure Description

Figure 1 As shown, existing sock sewing devices typically include a sewing head box 10 and a sewing component 20 (partially omitted in the figure) and a cutting component (not shown in the figure) located at one end of the sewing head box 10. The sewing component 20 has a sewing needle at the end away from the sewing head box 10. The sewing head box 10 is provided with several traction blocks 30 for guiding the sewing thread. The sock sewing device also includes: a torsion spring 40 located at the end of the sewing head box 10 away from the sewing component 20 for pulling back the remaining sewing thread during sewing, and a tensioner 50 for controlling the tension of the sewing thread. The sewing thread is introduced from one end of the sewing head box 10 and passes through the torsion spring 40, the tensioner 50 and each traction block 30 in sequence, and is finally fixed to the sewing needle of the sewing component 20 at the other end. The structures of the above sock sewing devices are all structures disclosed in the art.

[0036] In this utility model, the inner side of the fixed side plate 2 is fixed to the outer side of the seam head box 10. Correspondingly, the outline of the fixed side plate 2 corresponds to the outline of the seam head box 10 to maintain the consistency of the appearance of the seam head box 10. The fixed side plate 2 is locked to the outer side of the seam head box 10 by conventional fasteners. The outer side of the fixed side plate 2 is provided with several protruding fixing parts 21. The inner side wall of the dust cover 1 is provided with a locking part 11 corresponding to the fixing part 21, which engages with the fixing part 21. Specifically, the fixing part 21 is arranged horizontally, fixing... The outer side of part 21 is provided with a recessed part 22; the locking part 11 includes a housing 111, and a sliding groove 112 for the fixing part 21 to be inserted is formed in the housing 111. A spring piece 12 is provided on the dust cover 1 at the position corresponding to the locking part 11. The position of the spring piece 12 corresponds to the position of the sliding groove 112. There is a gap between the outer side of the spring piece 12 and the dust cover 1, which allows the spring piece 12 to deform. A protrusion 13 is provided on the side of the spring piece 12 facing the sliding groove 112, which engages with the recessed part 22. The protrusion 13 is located in the sliding groove 112.

[0037] It should be noted that since the fixed side plate 2 is fixed to the seam box 10 and cannot be moved, during actual installation, the locking part 11 of the dust cover 1 needs to be aligned with the fixing part 21 of the fixed side plate 2, the sliding groove 112 needs to be aligned with the fixing part 21, and then the locking part 11 needs to be moved towards the fixing part 21 so that the fixing part 21 is inserted into the sliding groove 112 of the locking part 11.
