Description

Technical Field

[0001] The present application relates to the technical field of knitting needle processing, and in particular to a high-stability back planing machine. Background Art

[0002] With the improvement of people's living standards, the styles of knitted garments are becoming increasingly diverse. In the production process of knitted garments, a knitting machine is generally used for knitting operations. A knitting needle is a main component on the knitting machine and is used to knit yarn into coils and connect the coils in series to form a knitted fabric. The structure and shape of the knitting needle have an important impact on the knitting loop formation process, the productivity of the knitting machine, and the quality of the product. There are generally multiple knitting needles on the knitting machine, and the multiple knitting needles cooperate with each other to complete the knitting operation of the knitted fabric.

[0003] After the knitting needle is stamped, there are many burrs. Workers use a back planing tool to polish the knitting needle, which provides convenience for the production of knitting needles. Manually polishing the knitting needle individually requires a lot of labor and time costs, and the polishing efficiency is low. Utility Model Content

[0004] In order to facilitate the back planing and polishing of knitting needles, the present application provides a high-stability back planing machine.

[0005] The present application provides a high-stability back planing machine, adopting the following technical solutions:

[0006] A high-stability back planing machine includes a machine body. A working plate is arranged on the machine body. A through hole for the knitting needle to pass through is opened on the working plate. A pushing mechanism for conveying the knitting needle is arranged on one side of the machine body. A supporting plate located below the through hole is arranged on the side of the working plate away from the pushing mechanism. The supporting plate is inclined. A conveyor belt located below the supporting plate is arranged on the machine body. A fixing mechanism located above the supporting plate is arranged on the machine body. A back planing mechanism for back planing and polishing the knitting needle is arranged on the side of the machine body close to the supporting plate.

[0007] By adopting the above technical solutions, the knitting needles are sequentially placed at the through hole, pushed to the upper part of the supporting plate by the pushing mechanism, fixed by the fixing mechanism, back planed by the back planing mechanism, and the back planed knitting needles fall onto the conveyor belt from the supporting plate for conveying, realizing automation.

[0008] Optionally, the pushing mechanism includes a pushing plate and a pushing cylinder. The pushing cylinder is horizontally installed on the machine body. The pushing plate is connected to the end of the piston rod of the pushing cylinder. The pushing plate faces the through hole, and the size of the pushing plate corresponds to that of the through hole.

[0009] By adopting the above technical solution, by starting the pushing cylinder, the pushing plate moves, and the knitting needle is pushed through the through-port and moved onto the support plate.

[0010] Optionally, a receiving mechanism for placing knitting needles is provided on one side of the working plate close to the pushing mechanism. The receiving mechanism includes two first receiving plates and two second receiving plates. The two first receiving plates are installed on the working plate in the vertical direction, and the distance between the two first receiving plates corresponds to the length of the knitting needle. The two second receiving plates are installed on the two first receiving plates and are located on the side where the two first receiving plates are close to each other.

[0011] By adopting the above technical solution, the knitting needles are sequentially placed between the two first receiving plates, and the second receiving plates limit the sides of the knitting needles. After the pushing mechanism pushes the knitting needles onto the support plate, the knitting needles placed between the two first receiving plates drop by the height of one knitting needle, so that the knitting needles fall onto the machine body in sequence and are pushed by the pushing mechanism.

[0012] Optionally, a connecting frame is provided on one of the first receiving plates, and a calibration needle is provided on the connecting frame close to the working plate side.

[0013] By adopting the above technical solution, the knitting needle is limited by the calibration needle.

[0014] Optionally, the fixing mechanism includes a fixing cylinder, a first connecting arm, a first connecting plate and a second connecting plate. The fixing cylinder is installed on the machine body in the vertical direction. One end of the first connecting arm is hinged to the end of the piston rod of the fixing cylinder, and the other end of the first connecting arm is rotatably connected to a first connecting plate. The second connecting plate is located between the first connecting plate and the support plate. The first connecting plate and the second connecting plate are connected by a third connecting plate. A fourth connecting plate is fixedly arranged below the first connecting plate. Two first connecting seats are provided on the working plate, and a first rotating shaft is rotatably connected between the two first connecting seats. A connecting ring is sleeved on the first rotating shaft. A fifth connecting plate is fixedly connected to the outer wall of the connecting ring. Two second connecting seats are provided on the fourth connecting plate, and a second rotating shaft is rotatably connected between the two second connecting seats. The second rotating shaft passes through the fifth connecting plate and is rotatably connected to the fifth connecting plate.

[0015] By adopting the above technical solution, whenever a knitting needle moves onto the support plate, the fixing cylinder is started, the piston rod of the fixing cylinder extends, and the first connecting plate is driven to move downward by the first connecting arm, so that the second connecting plate moves downward. The second connecting plate and the support plate clamp the knitting needle, so as to facilitate back planing of the knitting needle. When the first connecting plate and the second connecting plate move downward, the second connecting plate drives the connecting ring and the first rotating shaft to rotate, improving the stability of the fixing mechanism.

[0016] Optionally, a first spring plate is provided on the first connecting plate, a second spring plate is fixedly installed on the working plate, and an elastic spring is provided between the first spring plate and the second spring plate.

[0017] By adopting the above technical solution, during the downward movement of the first connecting plate, the elastic spring is compressed. During the upward movement and reset of the first connecting plate, the compressed elastic spring exerts an upward force on the first connecting plate through the first spring plate, facilitating the reset of the first connecting plate.

[0018] Optionally, the back planing mechanism includes a support table, a working cylinder, a reciprocating cylinder, a reciprocating seat, a driving seat, and a back planing knife. The support table is installed on the machine body, the working cylinder is installed in the support table, the driving seat is installed above the support table, a fixed rod is provided on the side wall of the support table, the piston rod of the working cylinder is connected to the driving seat through a second connecting arm, both ends of the second connecting arm are hinged to the end of the piston rod of the working cylinder and the side wall of the driving seat, the end of the fixed rod is hinged to the middle position of the second connecting arm, the reciprocating seat is located on the driving seat and is slidably connected to the driving seat, the reciprocating cylinder is installed in the machine body, and the end of the piston rod of the reciprocating cylinder is connected to the reciprocating seat. The back planing knife is installed on the side of the reciprocating seat close to the working plate.

[0019] By adopting the above technical solution, by starting the reciprocating cylinder, the piston rod of the reciprocating cylinder drives the reciprocating seat to reciprocate on the driving seat, and the back planing knife planes the surface of the knitting needle. Whenever the back planing knife planes the knitting needle, the working cylinder is started once, the piston rod of the working cylinder extends, and drives the driving seat to move towards the working plate through the second connecting arm, so that the back planing knife contacts the knitting needle to plane the knitting needle. After the back planing work is completed, the piston rod of the working cylinder retracts, causing the driving seat to move away from the working plate.

[0020] Optionally, a moving guide rail is provided on the driving seat along the moving direction of the piston rod of the reciprocating cylinder. A guide plate is provided on the reciprocating seat, and a guide wheel located in the moving guide rail is rotatably connected to the end of the guide plate.

[0021] By adopting the above technical solution, when the reciprocating seat reciprocates on the driving seat, the guide wheel moves in the moving guide rail, improving the stability of the reciprocating seat movement.

[0022] Optionally, a limiting plate is inclinedly provided on the side of the conveyor belt away from the support plate.

[0023] By adopting the above technical solution, the limiting plate blocks the knitting needles falling from the support plate, so that the knitting needles fall on the conveyor belt for conveying.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] Place the knitting needles at the passing openings in sequence, push the knitting needles above the support plate through the pushing mechanism, fix the knitting needles through the fixing mechanism, plane the backs of the knitting needles through the back planing mechanism, which facilitates the back planing and grinding of the knitting needles. After the back planing is completed, the knitting needles fall from the support plate onto the conveyor belt for transportation, realizing automation;

[0026] Whenever a knitting needle moves onto the support plate, start the fixing cylinder. The piston rod of the fixing cylinder extends, drives the first connecting plate to move downward through the first connecting arm, thereby causing the second connecting plate to move downward. The second connecting plate and the support plate clamp the knitting needle, thus facilitating the back planing of the knitting needle. When the first connecting plate and the second connecting plate move downward, the second connecting plate drives the connecting ring and the first rotating shaft to rotate, improving the stability of the fixing mechanism;

[0027] Start the reciprocating cylinder. The piston rod of the reciprocating cylinder drives the reciprocating seat to reciprocate on the driving seat. The back planing knife planes the surface of the knitting needle. Whenever the back planing knife planes the knitting needle, the working cylinder starts once. The piston rod of the working cylinder extends, drives the driving seat to move towards the working plate through the second connecting arm, makes the back planing knife contact the knitting needle, and planes the back of the knitting needle. After the back planing work is completed, the piston rod of the working cylinder retracts, making the driving seat move away from the working plate. Description of the Drawings
