Description

Technical Field

[0001] This utility model relates to the field of sock processing technology, specifically to a sewing device for sock processing. Background Technology

[0002] The toe-sewing process is a key step in sock production. The core of it is to sew the opening at the toe of the knitted sock closed, so that the sock forms a tubular structure.

[0003] In an effort to reduce costs, some factories still use semi-automatic sock toe-sewing machines. Operators need to manually tidy up the sock toe before placing it between the feed clamps and manually feeding it towards the toe-sewing machine. A skilled operator can move the sock very quickly, which means that the sock cannot be kept taut while it is being moved rapidly between the feed clamps. This causes the sock to be easily squeezed and wrinkled. After being sewn by the toe-sewing machine, these wrinkles result in creases at the toe, affecting both quality and appearance. Utility Model Content

[0004] The purpose of this invention is to provide a sewing device for socks. By setting a toothed disc inside the sock feeding clamp, the rotation of the toothed disc is used to clamp and transport the socks. This not only maintains the tension of the socks, but also transports the socks smoothly, so that the sock toes remain neat after sewing, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewing device for sock processing, comprising: The main body of the sock sewing machine; Two sets of sock feeding clamps are movably installed on one side of the main body of the sock sewing machine. Multiple sets of toothed discs are installed inside the sock feeding clamps via a rotating shaft. The opposing side of the toothed discs extends through to the outside of the sock feeding clamps to smoothly convey the socks. The sock feeding clamps are equipped with a drive component that drives the toothed discs. The outer side of the main body of the sock sewing machine is also equipped with an adjustment component for adjusting the distance between the two sets of sock feeding clips.

[0006] Preferably, the sock clip includes a base frame and a cover plate. The top of the cover plate has multiple sets of countersunk holes, and mounting bolts are movably disposed in the countersunk holes. The mounting bolts pass through the cover plate and are threadedly connected to the base frame.

[0007] Preferably, the drive assembly includes a synchronous pulley fixed to the outside of the rotating shaft, the inner cavity of the base frame is rotatably connected to multiple sets of guide wheels through bearings, the synchronous pulley and the outside of the guide wheels are connected by a synchronous belt, a set of micro motors are fixed to the top of the cover plate, the output shaft of the micro motors passes through the cover plate and is fixed with a connector, and the end of the set of rotating shafts is provided with a slot for engaging with the connector.

[0008] Preferably, the adjustment assembly includes a fixing frame fixed on the base frame, the fixing frame extending upward and slidably disposed within the fixing frame, the fixing frame being fixed on the side of the main body of the sock sewing machine, the inner cavity of the fixing frame being rotatably connected to a bidirectional screw via a bearing, a threaded sleeve being fixedly embedded in the upper end of the fixing frame, the threaded sleeve being threadedly engaged with the bidirectional screw, and a knob seat being fixed at one end of the bidirectional screw.

[0009] Preferably, two sets of limiting seats are fixed on the side wall of the main body of the sock sewing machine, and a limiting groove is opened on the side wall of the base frame, and the limiting seat is slidably disposed in the limiting groove.

[0010] Preferably, a guide strip is fixed to the top of the cover plate on the opposite side, the diameter of the front end of the guide strip gradually increases, and the rear ends of the two sets of guide strips are kept parallel.

[0011] Preferably, a controller is fixed to the outside of one of the base frames, and three sets of control buttons are respectively installed on the outside of the controller. The control buttons are electrically connected to the micro motor through the controller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention adjusts the distance between two sets of sock-feeding clips using an adjusting component, preventing the socks from falling directly due to excessive gaps between them. It also avoids squeezing and wrinkling of the socks between the clips. A drive component then drives multiple sets of toothed discs, which not only transport the socks but also maintain a certain tension for smooth movement. This prevents uneven tension during transfer, which could lead to stitching defects. Furthermore, the guide strips not only maintain the stability of the socks by utilizing the rolled edge at the toe but also tighten the rolled edge, ensuring neat stitching at the toe.

[0013] This invention allows for the control of the micro motor's start, stop, and reverse rotation via a control button, making it convenient for operators to cancel the sock conveying action and preventing improperly arranged socks from being directly sewn. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1-4 A sock-making sewing device is shown, comprising: Main body of the sock sewing machine 1; Two sets of sock feeding clips 2 are movably installed on one side of the main body 1 of the sock sewing machine. Multiple sets of toothed discs 3 are installed inside the sock feeding clips 2 through the rotating shaft 4. The opposite side of the toothed discs 3 extends through to the outside of the sock feeding clips 2 to smoothly convey the socks. The sock feeding clips 2 are equipped with a drive component 5 that drives the toothed discs 3. The outer side of the main body 1 of the sock sewing machine is also provided with an adjustment component 6 for adjusting the distance between the two sets of sock feeding clips 2; The distance between the two sets of sock-feeding clips 2 is adjusted by the adjusting component 6 to prevent the socks from falling directly due to excessive gaps between the clips 2. This also prevents the socks from wrinkling due to compression between the clips 2. The driving component 5 then drives multiple sets of toothed discs 3. The toothed discs 3 not only transport the socks but also maintain a certain tension for smooth movement, preventing uneven tension during the transfer of the socks and thus avoiding sewing defects. Moreover, under the constraint of the guide strip 9, the socks can not only maintain stability by utilizing the rolled edge of the toe but also have a certain tightening effect on the rolled edge, ensuring neat sewing of the toe.

[0018] Among them, such as Figure 3 As shown: The sock clip 2 includes a base frame 21 and a cover plate 22. The top of the cover plate 22 has multiple sets of countersunk holes, and mounting bolts 23 are movably installed in the countersunk holes. The mounting bolts 23 pass through the cover plate 22 and are threadedly connected to the base frame 21. The cover plate 22 and the base frame 21 can be fixedly installed by the mounting bolts 23, and the cover plate 22 can be easily removed to maintain the internal structure of the base frame 21.

[0019] Furthermore, such as Figure 3-4 As shown: The drive assembly 5 includes a synchronous pulley 51 fixed to the outside of the rotating shaft 4. The inner cavity of the base frame 21 is rotatably connected to multiple sets of guide wheels 52 via bearings. The synchronous pulley 51 and the outer side of the guide wheels 52 are connected by a synchronous belt 53. A set of micro motors 54 is fixed to the top of the cover plate 22. The output shaft of the micro motor 54 passes through the cover plate 22 and is fixed with a connector 55. The end of a set of rotating shafts 4 is provided with a slot 56 that engages with the connector 55. The micro motor 54 drives a set of rotating shafts 4 to rotate. Then, the other rotating shafts 4 rotate synchronously with the cooperation of the synchronous pulley 51 and the guide wheels 52. Then, the gear disc 3 on the rotating shaft 4 is synchronously driven, which facilitates the insertion of the gear disc 3 into the sock and the conveying and transfer of the sock along the sock clip 2.

[0020] Preferred, such as Figure 2 As shown: The adjustment assembly 6 includes a fixing frame 61 fixed on the base frame 21. The fixing frame 61 extends upward and slides within the fixing frame 62, which is fixed to the side of the main body 1 of the sock sewing machine. The inner cavity of the fixing frame 62 is rotatably connected to a bidirectional screw 63 via a bearing. A threaded sleeve 64 is fixedly embedded in the upper end of the fixing frame 61. The threaded sleeve 64 is threadedly engaged with the bidirectional screw 63. A knob seat 65 is fixed to one end of the bidirectional screw 63. The bidirectional screw 63 is rotated and driven by the knob seat 65, and then the two sets of fixing frames 61 are moved in opposite directions in conjunction with the threaded sleeve 64 to facilitate the adjustment of the distance between the two sets of sock feeding clips 2. A precise scale is provided on the knob seat 65 for precise control of the distance between the two sets of sock feeding clips 2.

[0021] It is worth noting that, such as Figure 1-2 As shown: Two sets of limiting seats 7 are fixed on the side wall of the main body 1 of the sock sewing machine. A limiting groove 8 is opened on the side wall of the base frame 21. The limiting seat 7 is slidably disposed in the limiting groove 8. Through the cooperation of the limiting seat 7 and the limiting groove 8, the sock feeding clip 2 is stably installed on the outside of the main body 1 of the sock sewing machine along with the fixing frame 62 and the fixing bracket 61. At the same time, the main body 1 of the sock sewing machine can move towards each other.

[0022] In a further preferred embodiment, such as Figure 3 As shown: A guide strip 9 is fixed to the top of the cover plate 22 on one side. The diameter of the front end of the guide strip 9 gradually increases, and the rear ends of the two sets of guide strips 9 are set in parallel. The guide strip 9 makes it easy for the rolled edge of the sock to be caught on the guide strip 9, preventing the sock from falling between the sock feed clips 2. At the same time, the guide strip 9 has the function of sorting and guiding, avoiding wrinkles on the rolled edge.

[0023] In addition, such as Figure 1-2 As shown: A controller 10 is fixed to the outside of a set of base frames 21. Three sets of control buttons 11 are installed on the outside of the controller 10. The control buttons 11 are electrically connected to the micro motor 54 through the controller 10. The controller 10 can control the micro motor 54, which can not only start and stop, but also reverse. This allows the socks stuck on the toothed disc 3 to be sent out from the inlet end of the sock feeder 2, avoiding operational errors that could affect the uniformity of the socks and the stitching quality of the sock toes.

[0024] The sock sewing machine is an existing piece of equipment, and its functions and principles will not be described in detail here.

[0025] In practical use, the equipment needs to be debugged before operation. The rotation angle of the knob seat 65 is precisely controlled by the dial on the knob seat 65. Then, the knob seat 65 drives the bidirectional screw 63 to rotate. The fixing frame 61 moves and adjusts in opposite directions within the fixing frame 62 with the cooperation of the threaded sleeve 64, thereby adjusting the distance between the sock feeding clips 2. Then, the operator follows the normal operating procedure to straighten the socks by "stretching, pinching, and tucking" the toe part, and then feeds them into the sock feeding clips 2. The rolled edge at the toe is caught on the outside of the guide strip 9, which not only supports the socks but also... The tension of the sock is maintained by the toothed disc 3 to prevent it from falling and to avoid further curling of the hem. After the sock enters the inside of the sock feeder 2, it is hooked by the toothed disc 3. Then, the micro motor 54 drives a set of rotating shafts 4 through the connector 55. Then, the other rotating shafts 4 rotate synchronously with the cooperation of the synchronous belt pulley 51, the guide wheel 52 and the synchronous belt 53, so that multiple sets of toothed discs 3 rotate synchronously. The toothed disc 3 at the front end conveys and transfers the sock toe, and then the toothed disc 3 at the rear end takes over the conveying. During the transfer process, the synchronous rotation of the toothed discs 3 can maintain the tension of the sock and prevent the sock from wrinkling.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
