Technical Field

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

[0002] Sewing thread refers to the thread used to sew textile materials, plastics, leather products, and to bind books and periodicals. It is characterized by its sewing ability, durability, and appearance quality. There are many types of sewing thread, which can be divided into natural fiber type, chemical fiber type, and blend type. During the production and processing of sewing thread, it is necessary to stretch the thread.

[0003] The existing stretching devices for sewing thread production have mature stretching technology, but they still have problems with poor dust removal, which leads to poor stretching effect. Utility Model Content

[0004] The purpose of this invention is to provide a stretching device for sewing thread production to solve the problems mentioned in the background art.

A dust extraction mechanism is provided above the base, and a cooling mechanism is provided inside the cooling box. The vacuuming mechanism includes: a front upright plate, a front suction pipe, a front pinion, a front slot, a front large gear, a hollow box, an air pipe, a filter box, an activated carbon plate, a curved pipe, a rear pinion, a rear large gear, a rear upright plate, a rear suction pipe, and a rear slot. The front upright plate is fixed above the base. The front suction pipe passes through the front upright plate and is rotatably connected at the point of penetration. The front slot is located on the outer wall of the front suction pipe. The front pinion is fixed to the outer wall of the front suction pipe. The front large gear is fixed to the outer wall of the low-speed rotating rod. The front large gear meshes with the front pinion. The inner wall of the hollow box is rotatably connected to the outer wall of the front suction pipe. The rear upright plate is fixed above the base. The rear suction pipe passes through the hollow box and is rotatably connected at the point of penetration. The rear slot is located on the outer wall of the rear suction pipe. The rear pinion is fixed to the outer wall of the rear suction pipe. The rear large gear is fixed to the outer wall of the rear suction pipe. The rear large gear and the rear small gear are meshed on the outer wall of the high-speed rotating rod. One end of the air pipe is fixed to the suction end of the exhaust fan, and the other end of the air pipe is fixed to the side wall of the filter box. The activated carbon plate is fixed inside the filter box. One end of the bent pipe is fixed to the side wall of the filter box, and the other end of the bent pipe is fixed above the hollow box. The rotation of the low-speed motor and the high-speed motor will cause the low-speed rotating rod and the high-speed rotating rod to rotate, which in turn causes the front large gear and the rear large gear to rotate, thereby causing the front small gear and the rear small gear to rotate. The operation of the exhaust fan causes dust to be sucked into the hollow box from the front slot and the rear slot.

[0006] Preferably, the rear pinion is fixed to the outer wall of the rear suction pipe, the rear large gear is fixed to the outer wall of the high-speed rotating rod, the rear large gear and the rear pinion mesh, one end of the air pipe is fixed to the suction end of the exhaust fan, the other end of the air pipe is fixed to the side wall of the filter box, the activated carbon plate is fixed inside the filter box, one end of the bent pipe is fixed to the side wall of the filter box, and the other end of the bent pipe is fixed to the top of the hollow box.

[0007] Preferably, the cooling mechanism includes: a bearing, a cross, a fan blade, a rotating shaft, a protrusion, a block, a connecting column, a spoiler, and a torsion spring. The cross is fixed to the inner wall of the air outlet, the bearing is fixed to the center of the cross, and the rotating shaft is fixed to the center of the bearing.

[0008] Preferably, the fan blade is fixed to the outer wall of the rotating shaft, the protrusion is fixed to the outer wall of the rotating shaft, the block is fixed to the inner wall of the cooling box, and the connecting post is fixed to the side of the block.

[0009] Preferably, the spoiler is hinged to the outer wall of the connecting column, one end of the torsion spring is fixed to the side of the block, and the other end of the torsion spring is fixed to the side of the spoiler. The fan blades located in the air outlet rotate with the airflow, which further drives the rotating shaft to rotate. The rotation of the rotating shaft will drive the protrusion to rotate. During the rotation, the spoiler will be intermittently agitated. The spoiler will shake repeatedly under the action of the torsion spring.

[0010] Compared with the prior art, the present invention provides a stretching device for sewing thread production, which has the following advantages: 1. The stretching device for sewing thread production uses a low-speed motor and a high-speed motor to rotate a low-speed rotating rod and a high-speed rotating rod, which in turn rotates a large front gear and a large rear gear, causing a small front gear and a small rear gear to rotate. The exhaust fan draws dust from the front and rear slots into the hollow box. The dust then enters the filter box through a curved pipe and is adsorbed by the activated carbon plate. Clean air is drawn into the exhaust fan. These actions achieve the effect of rotating the front and rear suction pipes to draw in dust, resulting in better dust collection and solving the problem of poor thread stretching caused by poor dust collection.

[0011] 2. The stretching device for sewing thread production has a fan blade located in the air outlet duct that rotates with the airflow, which in turn drives the rotating shaft to rotate. The rotating shaft drives the protrusion to rotate, and during the rotation, it intermittently agitates the baffle. The baffle repeatedly shakes under the action of the torsion spring, which achieves the effect of disturbing the airflow in the cooling box, making the cooling effect in the cooling box more uniform and solving the problem of uneven cooling that may be caused by the fixed airflow direction in the cooling box.

[0017] Working principle: First, the worker wraps the sewing thread three times around the low-speed rotating rod 8, and then three times around the high-speed rotating rod 9. Next, the sewing thread is passed through the inlet pipe 13 and the outlet pipe 12, and connected to the next process equipment. Then, the low-speed motor 6, the high-speed motor 7, and the exhaust fan 4 are turned on. The rotation of the low-speed motor 6 and the high-speed motor 7 will cause the low-speed rotating rod 8 and the high-speed rotating rod 9 to rotate, which in turn causes the front large gear 105 and the rear large gear 112 to rotate, thereby causing the front small gear 103 and the rear small gear 111 to rotate. The operation of the exhaust fan 4 causes dust to be sucked into the hollow box 106 from the front slot 104 and the rear slot 115.

The above actions achieve the effect of the front suction pipe 102 and the rear suction pipe 114 rotating to suck up dust, making the dust collection effect better. The exhaust pipe of the exhaust fan 4 blows high-speed, clean airflow into the cooling box 10 to cool and shape the sewing thread inside. The fan blades 203 located at the air outlet 11 rotate with the airflow, which in turn drives the rotating shaft 204 to rotate. The rotation of the rotating shaft 204 drives the protrusion 205 to rotate. During the rotation, the deflector 208 is intermittently agitated. The deflector 208 is repeatedly shaken under the action of the torsion spring 209, which achieves the effect of disturbing the airflow inside the cooling box 10, making the cooling effect inside the cooling box 10 more uniform.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
