[0005] In order to facilitate the transportation of knitting needles, this application provides a rolling and flattening machine for knitting needles.

[0006] This application provides a rolling and flattening machine for knitting needles, adopting the following technical solutions:

[0007] A rolling and flattening machine for knitting needles includes a machine body. On the machine body, there is a rolling and flattening mechanism for flattening knitting needles. On the machine body, there is a placement rack near the input end of the rolling and flattening mechanism. The placement rack is arranged vertically. At the top of the placement rack, there is a placement opening. At the bottom of the placement rack, near the input end of the rolling and flattening mechanism, there is a discharge opening arranged vertically. On the machine body, there is a pushing cylinder arranged horizontally. At the end of the piston rod of the pushing cylinder, there is a pushing block. The height of the pushing block is the same as that of the placement opening. On the placement rack, there is a pushing opening for the pushing block to pass through.

The pushing cylinder is started, and the pushing block moves to push the lowermost knitting needle in the placement rack out from the discharge opening and push it into the rolling and flattening mechanism. With the reciprocating movement of the piston rod of the pushing cylinder, the pushing block sequentially pushes the knitting needles into the rolling and flattening mechanism, facilitating the transportation of the knitting needles.

[0009] Optionally, an adjustment opening with a width smaller than the width of the knitting needle is formed in the placing rack along the vertical direction at one end close to the input end of the flattening mechanism.

[0010] By adopting the above technical solution, it is convenient for workers to adjust the knitting needles that are offset during the falling process in the placing rack through the adjustment opening.

[0011] Optionally, the flattening mechanism includes a fixed frame, two upper connecting frames and two lower connecting frames. The fixed frame is installed on the machine body. The two lower connecting frames are installed on the fixed frame and are parallel to each other. The two upper connecting frames and the two lower connecting frames correspond one by one. A plurality of upper rollers are arranged between the two upper connecting frames, and a plurality of lower rollers are arranged between the two lower connecting frames. The upper rollers and the lower rollers are arranged in a staggered manner.

[0012] By adopting the above technical solution, when the knitting needle passes through the flattening mechanism, the upper rollers and the lower rollers rotate simultaneously, and the knitting needle is flattened during the movement of the knitting needle.

[0013] Optionally, connecting gears are coaxially and fixedly connected to the same-side ends of a plurality of the upper rollers and the lower rollers, and intermediate gears are meshed and connected between adjacent connecting gears.

[0014] By adopting the above technical solution, through the meshing connecting gears and the intermediate gears, the upper rollers are connected to each other, and rotating one upper roller can drive all the upper rollers to rotate synchronously. Similarly, the lower rollers are connected to each other, and rotating one lower roller can drive all the lower rollers to rotate synchronously.

[0015] Optionally, a lifting screw rod is rotatably connected to the fixed frame along the vertical direction. One of the upper connecting frames is threadedly connected to the lifting screw rod. A guide rod is arranged along the vertical direction on one side of the fixed frame away from the lifting screw rod. The guide rod passes through the other upper connecting frame and is movably connected to the upper connecting frame.

[0016] By adopting the above technical solution, by rotating the lifting screw rod, the lifting seat drives the two upper connecting frames to move, so as to adjust the position between the upper connecting frame and the lower connecting frame.

[0017] Optionally, the machine body is provided with a receiving mechanism at the output end of the flattening mechanism. The receiving mechanism includes a receiving rack and two receiving screw rods. The two receiving screw rods are rotatably connected to the receiving rack, and the two receiving screw rods are parallel to each other.

[0018] By adopting the above technical solution, the knitting needles flattened by the flattening mechanism fall on the two receiving screw rods, and the receiving screw rods rotate to convey the knitting needles, so that the knitting needles are placed in sequence.

[0019] Optionally, a baffle is inclinedly arranged on one side of the receiving rack away from the machine body.

[0020] By adopting the above technical solution, the knitting needles are limited by the baffle to prevent the support from falling outside the storage rack.

[0021] Optionally, connecting sprockets are coaxially and fixedly connected to the same end of the two storage screws, and the two connecting sprockets are connected by a connecting chain.

[0022] By adopting the above technical solution, one of the storage screws is rotated, and the other storage screw is driven to rotate synchronously through the connecting sprockets and the connecting chain.

[0024] The knitting needles are sequentially placed in the placement rack from the placement opening, the pushing cylinder is started, the pushing block moves, and the bottommost knitting needle in the placement rack is pushed out from the discharge opening and pushed into the flattening mechanism. As the piston rod of the pushing cylinder reciprocates, the pushing block sequentially pushes the knitting needles into the flattening mechanism, facilitating the transportation of the knitting needles.
