Description

Technical Field

[0001] This utility model belongs to the field of textile processing technology, specifically relating to a yarn stretching and traction mechanism. Background Technology

[0002] Stretching and drawing of the fiber top is an important step in the textile process. Its main purpose is to stretch the fiber using mechanical equipment such as a stretching machine or drawing machine, so that the molecular chains are aligned along the fiber axis, thereby improving the strength and toughness of the fiber. The degree and speed of stretching need to be adjusted according to the properties of the fiber.

[0003] When stretching wool slivers, heating is usually required. Strict temperature control is essential to ensure fiber quality and performance. Improper temperature settings may lead to overstretching or understretching of the fibers, thus affecting their strength and uniformity.

[0004] In the existing process of stretching and pulling wool strips, heating plates are usually used to heat the wool strips. However, since the heating plate is fixed in position, it is not possible to effectively heat the four sides of the wool strip during traction. Furthermore, the heating plate is fixed in length and the required temperature varies depending on the material of the wool strip. This results in poor heating efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the issue that, during the stretching and traction process of existing wool strips, some parts cannot be heated due to inconsistent lengths, which affects the quality, and the wool strips cannot be effectively and evenly heated around their perimeter during the heating process.

[0006] To solve the above-mentioned technical problems, the present invention provides a sliver stretching and traction mechanism, comprising a base, an mounting block fixedly connected to the upper surface of the base, a motor fixedly connected to the side surface of the mounting block, a gear fixedly connected to the output end of the motor, a turntable rotatably connected to the inner side wall of the mounting block, a rack fixedly connected to the side surface of the turntable, a fixed heating device fixedly connected to the inner side wall of the turntable, the fixed heating device comprising a horizontal plate, a first heating plate, a sliding groove and a slot, a slider movably connected to the inner wall of the sliding groove, a movable heating plate fixedly connected to the side surface of the slider, an installation groove provided on the side surface of the slider, a pressing device rotatably connected to the inner side wall of the installation groove, a second heating plate switch provided on the side surface of the slider, a telescopic cylinder fixedly connected to the inner side wall of the base, and a stretching plate fixedly connected to the output end of the telescopic cylinder.

[0007] Through the above technical solution, after the clamping device clamps the wool strip, the stretching plate is pushed by the telescopic cylinder to stretch the wool strip. When it is pushed, the moving heating plate is pulled out at the same time, so that it can heat wool strips of different lengths. When it is pulled out, one end of the pressing plate of the pressing device will pop out under the action of the spring, causing the pressing hook plate to move and press the switch of the second heating plate, so that the corresponding second heating plate opens to heat the wool strip. At the same time, the motor is started to make the first heating plate and the moving heating plate rotate to heat the wool strip evenly.

[0008] The present invention is further configured such that the side surface of the rack meshes with the gear, the side surface of the mounting block is fixedly connected to the mounting frame, the side surface of the mounting frame is fixedly connected to the clamping device, the clamping device includes a mounting post, a clamping disc and several bolts, one end of the mounting post is fixedly connected to the mounting frame, and the bolts are threadedly connected to the clamping disc.

[0009] The above technical solution enables the motor to drive the gear to rotate, which in turn drives the rack and turntable to rotate, causing the first heating plate and the moving heating plate to rotate and heat the surrounding area of ​​the clamped wool strip evenly.

[0010] The present invention is further configured such that the side surface of the mounting column is movably connected to the turntable, and the side surface of the mounting column is fixedly connected to the mounting bracket.

[0011] Through the above technical solution, the fixed connection between the mounting column and the mounting frame makes the clamping device installed stably and firmly, and the mounting column and the mounting block cooperate to restrict the position of the turntable.

[0012] The present invention is further configured such that a guide bolt is fixedly connected to the upper surface of the movable heating plate, the side surface of the guide bolt is movably connected to the slot, and a plurality of second heating plates are fixedly connected to the lower surface of the movable heating plate.

[0013] Through the above technical solution, the guide bolt is used to guide and limit the displacement of the moving heating plate.

[0014] The present invention is further configured such that the pressing device includes a pressing plate, a pressing hook plate and a spring, the two ends of the spring are respectively fixedly connected to the mounting groove and the pressing plate, and the pressing hook plate passes through the slider to the interior of the movable heating plate.

[0015] With the above technical solution, the pressing device automatically opens the corresponding second heating plate for heating when the moving heating plate is pulled out, eliminating the need for manual control and reducing manpower.

[0016] The present invention is further configured such that the side surface of the pressing hook plate is movably connected to the second heating plate switch.

[0017] The above technical solution allows the pressing hook plate to be used to turn the second heating plate switch on and off.

[0018] The present invention is further configured such that the end of the slide away from the turntable is chamfered, a handle is fixedly connected to the side surface of the movable heating plate, and a groove is provided on the inner side wall of the stretching plate.

[0019] Through the above technical solution, the chamfering treatment makes the pressing plate of the pressing device press back more smoothly when the moving heating plate is pushed back.

[0020] The present invention is further configured such that a cylindrical locking block is provided on the side surface of the handle, and the side surface of the cylindrical locking block is movably connected to the groove.

[0021] With the above technical solution, the cylindrical block is locked in the groove so that the stretching plate pulls out the moving heating plate when it moves.

[0022] The present invention is further configured such that the number of the second heating plate switches is the same as the number of the second heating plates.

[0023] The beneficial effects of this utility model are as follows: By cooperating with the clamping device, the fixed heating device, the movable heating plate, the pressing device, the motor, the gear, the turntable, the stretching plate and the telescopic cylinder, the movable heating plate is synchronously pulled out when the wool strip is clamped and stretched. At this time, the pressing plate of the corresponding pulled-out second heating plate will pop out the pressing hook plate to press the switch of the second heating plate, so that the second heating plate is turned on to heat the stretched wool strip. Moreover, the fixed heating device and the movable heating plate can rotate to heat the wool strip evenly around its perimeter, avoiding the problem of uneven heating or partial inadequate heating leading to poor wool strip quality.
