Description

Technical Field

[0001] The utility model relates to the technical field of flat sewing machines, in particular to an adjusting device for a flat sewing machine for knitted products. Background Art

[0002] A flatbed sewing machine, also known as a flatbed sewing machine, is a machine that uses an electric needle to sew wire harnesses horizontally on pieces of cloth, leather, etc. The traces are neat and the wire harnesses are firm, and the stitches can be sewn at equal distances. Due to the fixed position of the flatbed sewing machine, the raw materials can only be pushed by moving pieces of cloth or leather.

[0003] In order to facilitate loading and unloading, an adjustment device is often installed on the table of the flat lathe. Although it is convenient to extract and place the materials to be processed, it lacks a corresponding tensioning structure. As the materials are pushed, looseness is inevitable, and the sewing effect of the flat lathe cannot be maintained.

[0004] Now, a novel adjustment device for a flat sewing machine for knitted goods is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an adjustment device for a flat-bed sewing machine for knitted goods, so as to solve the problem of lack of a tightening structure in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flat lathe adjustment device for knitwear, comprising a workbench and a rectangular chamber, a rectangular chamber is arranged on the left side inside the workbench, and the front and rear ends of the rectangular chamber are both provided with through grooves, a movable plate is horizontally placed in the rectangular chamber, and cylindrical grooves are respectively arranged between the front and rear ends of the left and right sides of the movable plate, an electric shaft is movably installed between the front and rear ends of the cylindrical groove, and baffles are welded on the front and rear ends of the outside of the electric shaft, hanging blocks are fixed on the front and rear ends above the cylindrical groove, and a cylinder is installed above the hanging block, a positioning plate is horizontally welded between the bottom ends of the piston rods of the cylinders, and a cloth piece is wrapped between one side of the surface of the electric shaft.

[0007] Preferably, the positioning plate is vertically located above the electric rotating shaft, and the cylinder can control the positioning plate to slide up and down.

[0008] Preferably, the cloth piece is embedded in the gap between the electric rotating shaft and the positioning plate, and the electric rotating shaft can pull the cloth piece located in the activity space left and right.

[0009] Preferably, a movable chamber is provided between the front and rear of the inner center of the workbench, and a screw is movably connected in the movable chamber, a shaft sleeve is sleeved on the outside of the screw, and the left side of the shaft sleeve is fixedly connected to the movable plate, and the front and rear of the right side of the shaft sleeve are movably embedded with balls, a motor is installed at the center of the front end of the workbench, and the output shaft of the motor is fixedly connected to the screw.

[0010] Preferably, the outer wall of the ball is in contact with the movable chamber, and the sleeve is meshed with the screw rod by means of an internal thread.

[0011] Preferably, fixed blocks are installed at both the front and rear locations on the left side of the outside of the workbench, and a cavity is provided on the inner side of the fixed block, a reel is installed between the front and rear of the inner side of the cavity, a motor is installed above the front end of the fixed block, a level is installed below the front end of the fixed block, a lifting rope is wound in the reel, and a positioning block is fixed on the top of the lifting rope, and a flat car machine body is installed on the right side of the top of the workbench.

[0012] Preferably, the output shaft of the motor is fixedly connected to the reel, and the reel can rotate in the cavity.

[0013] Preferably, the lifting rope is connected between the drum and the positioning block, and the right side of the positioning block is mounted on the flat car machine body by means of screws.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the adjustment device for a flat sewing machine for knitted goods not only realizes the flattening of the material to be sewn and the adjustment of the orientation of the cloth piece, but also realizes the stability of the device;

[0015] (1) By placing a movable plate horizontally in a rectangular chamber, the two sides of the cloth and leather are respectively wound on the electric rotating shaft, and the cylinder on the top of the hanging block vertically lifts and lowers the positioning plate through the piston rod. When the electric rotating shaft stops winding and unwinding, the cloth can be pressed and fixed, which can not only tighten and flatten the cloth, but also horizontally adjust the position of the cloth corresponding to the needle head of the flat sewing machine body to prevent the pins from loosening and twisting;

[0016] (2) A motor is installed at the center of the front end of the workbench. The motor at the front end of the workbench is turned on to rotate the screw in the moving chamber. Under the lubrication of the ball bearing, the movable plate moves forward and backward in the rectangular chamber along the left wall of the moving chamber. The cloth piece that can be translated left and right can also move forward and backward. This can expand the push range of the machine sewing and achieve the purpose of adjusting the position of the cloth piece in multiple directions.

[0017] (3) By installing fixed blocks at the front and rear positions on the left side of the workbench, the external motor is started to adjust the rotation angle of the reel in the cavity, and then the lifting rope is stretched and tightened. Since the lifting rope is fixed on the flat car body through the positioning block, the moving position of the water droplets on the level can be observed to level the adjustment device, so that the mechanism for pushing and moving the cloth piece is level with the workbench, avoiding excessive vibration when moving the cloth piece inside the adjustment device.
