The shovel-shaped brush head is made of a hard material. This sock toe-sewing machine, by setting multiple circular and shovel-shaped brush heads, can not only sweep away and clean the waste material above the blade generated during the sock toe-sewing process, but also sweep away and clean the waste material that falls into the gap between the blades during the sock toe-sewing process.

Description

Technical Field

[0001] This invention relates to the field of sewing machine technology, specifically a sock sewing machine. Background Technology

[0002] Knitted socks are cylindrical with open ends, requiring a sock toe-sewing machine to sew one end shut. A sock toe-sewing machine is a specialized piece of equipment for processing socks with open ends, essentially sewing the toe closed. Normally, when sewing the toe, excess material is trimmed before the cut is sewn shut. However, with a straight-line sock toe-sewing machine, the sock passes through the first and second sewing points before the toe is finished. During this process, thread ends or other waste material are generated, which can easily become tangled on the machine head or frame and cannot be cleaned promptly, thus affecting the normal operation of the machine.

[0003] For example, the patent with application number CN201921347479.0 achieves the function of collecting waste by setting a waste collection mechanism, a connecting pipe connected to the collection hood and the collection box on the frame. However, since the cutting blade of the straight sewing machine is long and thin, this patent only sets a connecting pipe on the frame to collect waste through a vacuum pump. This is prone to incomplete waste collection. Only the waste near the location of the connecting pipe can be collected, while the waste on the cutting blade is difficult to collect. At the same time, when the device is running in the sock sewing machine, it is possible that when the waste is sucked to the position of the connecting pipe, the waste may fall into the cutting blade, causing the machine to stop running.

[0004] For example, the patent with application number CN201921347479.0 sets up a waste collection device including a suction drive device, a waste collection bin, a suction pipe, a diverter, one main air pipe and two auxiliary air pipes to collect waste generated during the sewing process of socks. However, because its air pipe has too many bends, and all of them are sharp 90-degree turns, it is not easy to control the airflow setting when using the suction device. If the airflow is too strong, it may affect the normal operation of the machine. If the airflow is too weak, it will not be able to suck up all the waste on the cutting blade. In addition, when the device is running while the sock sewing machine is working, it may cause the waste to fall into the cutting blade when it is sucking up the waste, causing the machine to stop running.

[0005] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a sock sewing machine that solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sock sewing machine, comprising a support base, a support plate mounted on the support base, a cutting blade mounted on the support plate, the cutting blade having a groove in the middle, waste material scattered randomly on the cutting blade, and waste material embedded in the groove, a collecting structure and a driving structure connected to the support plate, the collecting structure moving horizontally along the length of the cutting blade via the driving structure, the collecting structure comprising a brush head connecting plate, a circular brush head and a shovel-shaped brush head mounted on the outer sidewall of the brush head connecting plate, the circular brush head corresponding to the upper side of the cutting blade, the inner end of the shovel-shaped brush head extending down into the groove, and the shovel-shaped brush head being made of a hard material.

[0008] Preferably, the driving structure includes a displacement plate located on the inner sidewall of the brush head connecting plate. A serrated groove is provided at the lower end of the displacement plate. An external gear is rotatably connected below the displacement plate. The external gear rotates left and right, driving the displacement plate to reciprocate laterally.

[0009] Preferably, the collection structure is provided at intervals and is located on each side of the shearing blade, so that every piece of waste on the long shearing blade will be collected by the collection structure.

[0010] Preferably, the size of the shovel-shaped brush head is half the width of the groove, and shovel-shaped brush heads are provided on both sides. Their cooperation ensures that no small amount of fertilizer remains in the groove of the shearing tool.

[0011] Preferably, the external gear has a threaded slot in the middle, the threaded slot is connected to a threaded post, the threaded post is connected to one end of a connecting rod, and the other end of the connecting rod is connected to a transmission gear.

[0012] Preferably, the circular brush heads and shovel-shaped brush heads are evenly arranged on the side wall of the brush head connecting plate, and the shovel-shaped brush heads are staggered among the circular brush heads.

[0013] Preferably, the lower end of the displacement plate is provided with a protrusion, and the protrusion is slidably connected to the slide rail.

[0014] Preferably, the length of the lateral reciprocating movement of the displacement plate is twice the length of the displacement plate.

[0015] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] This invention discloses a sock sewing machine. By using multiple reciprocating brush head connecting plates arranged at equal intervals and brush heads mounted on the brush head connecting plates, it can collect and clean the waste material remaining on the entire cutting blade. This avoids the problem of only collecting waste material remaining on the upper part of the blade, which would cause waste material to accumulate on the upper part of the long cutting blade and affect the normal operation of the machine. Moreover, the brush head connecting plates are located on the upper side of the cutting blade edge, and can be started simultaneously when the machine is sewing socks to collect and clean the waste material.

[0017] This invention discloses a sock-sewing machine. It incorporates two types of brushes: multiple circular brush heads and shovel-shaped brush heads evenly distributed among the circular brush heads. As the brush head connecting plate reciprocates, the circular brush heads sweep away waste material normally generated above the cutting blades during the sock-sewing process. If some waste material falls into the gaps between the cutting blades, the shovel-shaped brush heads collect this waste material. The shovel-shaped brush heads collect and clean this waste material as the brush head connecting plate moves, preventing the machine from having to stop and remove the waste material when it falls into the gaps between the blades.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-3As shown: A sock sewing machine includes a support base 1, a support plate 2 on the support base 1, and a cutting blade 3 on the support plate 2. The cutting blade 3 has a groove 20 in the middle, and waste material is scattered on the cutting blade 3. Waste material is embedded in the groove 20. A collection structure and a driving structure are connected to the support plate 2. The collection structure moves horizontally along the length of the cutting blade 3 through the driving structure. The collection structure includes a brush head connecting plate 10, a circular brush head 11 and a shovel-shaped brush head 12 set on the outer side wall of the brush head connecting plate 10. The circular brush head 11 corresponds to the upper side of the cutting blade, and the inner end of the shovel-shaped brush head 12 extends down to the groove 20. The shovel-shaped brush head 12 is made of hard material. By setting multiple brush head connecting plates 10 that move back and forth at equal intervals and the brush heads set on the brush head connecting plates, the waste material remaining on the entire cutting blade can be collected and cleaned. This avoids only collecting the waste material remaining on the upper part of the blade, which would cause waste material to accumulate on the upper part of the long cutting blade and affect the normal operation of the machine.

[0028] The driving structure includes a displacement plate 7 located on the inner side wall of the brush head connecting plate 10. A serrated groove 8 is provided at the lower end of the displacement plate 7. An external gear 9 is rotatably connected below the displacement plate 7. The external gear 9 rotates left and right, driving the displacement plate 7 to move laterally back and forth.

[0029] Multiple collection structures are spaced apart and located on each side of the shearing blade 3, so that every piece of waste on the long shearing blade will be collected by the collection structures.

[0030] The shovel-shaped brush head 12 is half the width of the groove, and shovel-shaped brush heads are provided on both sides. Their cooperation ensures that no small fertilizer particles remain in the groove of the shearing tool.

[0031] The external gear 9 has a threaded slot 16 in the middle, and a threaded post 6 is rotatably connected to the threaded slot 16. One end of the threaded post 6 is connected to a connecting rod 5, and the other end of the connecting rod 5 is connected to the transmission gear 4.

[0032] Circular brush heads 11 and shovel-shaped brush heads 12 are evenly arranged on the side wall of the brush head connecting plate 10. The shovel-shaped brush heads 12 are staggered among the circular brush heads 11. By setting both circular brush heads and shovel-shaped brush heads evenly arranged among the circular brush heads, when the brush head connecting plate moves back and forth, the circular brush heads sweep away and clean the waste material located above the cutter during the process of cutting the sock toe. If some waste material generated during the process of cutting the sock toe falls into the gap 20 between the cutters, the shovel-shaped brush heads can collect this waste material and clean it up as the brush head connecting plate moves.

[0033] The lower end of the displacement plate 7 is provided with a protrusion 19, which is slidably connected to the slide rail 14. The displacement plate can move left and right through the cooperation between the protrusion and the slide rail.

[0034] The transverse reciprocating length of the displacement plate 7 is twice the length of the displacement plate 7. Multiple collection structures and driving structures are provided at equal intervals to collect and clean the waste on the entire shearing cutter 3.

[0035] The working principle of this device is as follows:

[0036] like Figure 4-6 As shown: Under normal conditions, when the sock sewing machine is started, the sock is passed through the cutting blade 3 and the toe is sewn. Waste material is generated during the process. At this time, the drive motor 15 is turned on, which drives the gear on it to rotate. This causes the rotating gear 18, which is connected to the rotating gear through the drive belt, to rotate. The rotation of the rotating gear 18 drives the drive gear 4 to move in a circle around the rotating gear 18. When the drive gear 4 moves clockwise to the right of the rotating gear 18, the threaded column 6 and the connecting rod 5 are horizontal. The threaded column 6 moves backward to the extreme point, which drives the shift plate 7 to move to the left to the extreme point. At this time, the brush head connecting plate 10 and the circular brush head 11 move to the left during this process and sweep away and clean the waste material generated after the sock toe is sewn.

[0037] When the transmission gear 4 continues to move clockwise in a semicircle to the left of the rotating gear 18, it drives the threaded column 6 to move forward to the extreme point, thereby causing the displacement plate 7 to move from the leftmost to the rightmost. During this process, the brush head connecting plate 10 and the circular brush head 11 also move from the leftmost to the rightmost, completing a cleaning of the waste generated after sewing the socks from left to right.

[0038] When some waste material generated after sewing the socks falls into the middle gap of the cutting blade 3, the downward extension length of the shovel-shaped brush head 12 provided on the brush head connecting plate 10 is just enough to allow it to enter the middle gap of the cutting blade 3. Through the protrusion provided at the downward extension end of the shovel-shaped brush head 12, it can hook the waste material that has fallen into the middle gap of the cutting blade 3, and then collect and clean the waste material in the gap as the brush head connecting plate 10 and the displacement plate 7 move left and right.

[0039] By evenly arranging multiple collection and driving structures around the long shearing blade 3, they work together to collect the waste material on the shearing blade 3 to the end. Then, the waste material is sucked into the collection box by the suction of a vacuum pump, thus realizing the processing of the waste material.

[0040] This device uses multiple reciprocating brush head connecting plates 10 arranged at equal intervals and brush heads provided on the brush head connecting plates 10 to collect and clean the waste material remaining on the entire cutting blade 3. This avoids only collecting the waste material remaining on the blade, which would cause waste material to accumulate on the upper part of the long cutting blade 3 and affect the normal operation of the machine. In addition, the brush head connecting plates 10 are set on the upper side of the cutting edge of the cutting blade 3, and can be started simultaneously when the machine is running to sew the toes of socks to collect and clean the waste material.

[0041] By setting the brush heads on the brush head connecting plate 10 into two types—circular brush heads 11 and shovel-shaped brush heads evenly arranged among the circular brush heads—it can handle waste materials scattered on the shearing blade 3 and those falling into the gaps between the shearing blade 3. In response to various situations, the waste materials are collected and cleaned as the brush head connecting plate moves, avoiding situations where the machine has to be shut down to clean up the waste materials.

[0042] The above-described embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
