Description
Technical Field
[0001] The utility model relates to the field of yarn shearing, in particular to a yarn shearing device. Background Art
[0002] Yarn is a textile product made of various textile fibers into a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. During the production and processing of yarn, it is usually necessary to wind the formed yarn on a reel. When the appropriate amount is wound, the yarn needs to be cut.
[0003] The commonly used method at present is to cut the yarn manually with scissors. However, when the yarn is produced in the factory, multiple yarns will be transmitted from all directions, and only one yarn can be cut each time. It is impossible to cut multiple yarns at the same time. At the same time, if a large knife is used for unified cutting, the yarn direction cannot be unified because the yarns will be transmitted from all directions. If multiple independent yarns are bundled together and cut, the yarns will also be tangled together. At this time, it is necessary to manually untie the tangled yarns, which is very inconvenient.
[0004] Therefore, it is necessary to invent a yarn shearing device. Utility Model Content
[0005] The purpose of the utility model is to solve the problems raised in the above background technology.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a yarn shearing device, comprising a fixed frame, a first adjusting component and a second adjusting component are arranged on both sides of the inner cavity of the fixed frame, a driving gear is installed between the first adjusting component and the second adjusting component, a rotating shaft is installed in the middle of the driving gear, an upper knife seat is installed at the lower end of the second adjusting component, a lower knife seat is installed at the lower end of the first adjusting component, a shearing blade is installed at one end of the upper knife seat aligned with the lower knife seat, and a guide component is installed at the upper end of the lower knife seat away from the shearing blade.
[0007] Based on the above features: when it is necessary to shear the yarn in various directions, the yarn will first pass through the guide assembly, and then the yarn will pass through the middle of the upper knife seat and the lower knife seat. When it is necessary to shear the yarn, the rotating shaft is used to drive the driving gear to rotate. When the driving gear rotates, it can drive the first adjusting assembly to move upward, and the second adjusting assembly to move downward. At this time, the first adjusting assembly and the second adjusting assembly will drive the upper knife seat and the lower knife seat to move synchronously, so that the shear blades at one end of the upper knife seat and the lower knife seat can cut the yarn, which is simple and convenient.
[0008] Preferably, the first adjustment component includes a fixed plate A and a movable toothed plate A slidably connected in the middle of the fixed plate A, and the movable toothed plate A is meshingly connected with the driving gear.
[0009] Based on the above characteristics: when the driving gear rotates forward, one side of the driving gear will engage with the moving tooth plate A, so that the moving tooth plate A drives the lower knife seat to move upward, and when the driving gear rotates reversely, the moving tooth plate A drives the lower knife seat to move downward.
[0010] Preferably, the second adjustment assembly includes a fixed plate B and a movable tooth plate B slidably connected in the middle of the fixed plate B, and guide grooves are symmetrically provided on both sides of the inner cavity of the fixed plate A and the fixed plate B.
[0011] Based on the above characteristics: when the driving gear rotates forward, the side of the driving gear away from the moving tooth plate A will engage with the moving tooth plate B. At this time, the moving tooth plate B will drive the upper tool holder to move downward. When the driving gear rotates reversely, the moving tooth plate B will drive the upper tool holder to move downward.
[0012] Preferably, guide sliders are symmetrically installed on both sides of the movable tooth plate B and the movable tooth plate A, and buffer springs are installed on the top ends of the movable tooth plate B and the movable tooth plate A.
[0013] Based on the above characteristics: the movable tooth plate A and the movable tooth plate B are slidably connected through the guide slider and the guide groove, the movable tooth plate A and the movable tooth plate B move in opposite directions, and when the movable tooth plate A or the movable tooth plate B moves, the two will squeeze or stretch the buffer spring for buffering, thereby strengthening the movement resistance of the shear blade and avoiding collision when the two relatively aligned shear blades are fitted together.
[0014] Preferably, a T-shaped slide groove is provided at one end of the upper knife seat aligned with the lower knife seat, lugs are symmetrically installed on both sides of the upper knife seat and the lower knife seat, a through hole is provided in the middle of the lug, and a positioning pin is installed inside the through hole.
[0015] Based on the above features: after the shear blade is inserted into the T-shaped slide slot, the positioning pin can be used to pass through the through hole in the middle of the lug, so that the positioning pin can be limited on both sides of the upper blade seat and the lower blade seat to prevent the shear blade from separating from the T-shaped slide slot. When disassembly is required, just pull out the positioning pin and then pull the shear blade out of the T-shaped slide slot.
[0016] Preferably, two shear blades are provided, and a T-shaped handle is installed at one end of the shear blade.
[0017] Based on the above features: the two shear blades are inserted into the inner side of the T-shaped slide groove using the T-shaped handle, and then the positioning pins are used to limit the positions on both sides of the T-shaped handle. At this time, the shear blades cannot fall down by themselves.
[0018] Preferably, the guide assembly includes a support and a first guide roller and a second guide roller installed in the middle of the support, a limiting groove is provided on the surfaces of the first guide roller and the second guide roller, and bearing seats are installed at both ends of the first guide roller and the second guide roller.
[0019] Based on the above features: when multiple yarns pass through the first guide roller and the second guide roller at the same time, a single yarn can be located inside the limiting groove, so that the limiting groove can separate the multiple yarns to avoid multiple yarns coming from all directions from being entangled together.
[0020] The beneficial effects of the utility model are:
[0021] 1. It is convenient to uniformly cut the yarns transmitted in all directions. During operation, multiple yarns are first passed through the middle of the first guide roller and the second guide roller at the same time to keep the yarn transmission direction consistent. Then the yarns with the same direction will pass through the middle of the upper knife seat and the lower knife seat. Then the driving gear is used to drive the movable tooth plate A and the movable tooth plate B to move in opposite directions. When the movable tooth plate A moves upward, the shear blade at one end thereof can be driven to move upward through the lower knife seat, and when the movable tooth plate B moves downward, the shear blade at one end thereof can be driven to move upward through the upper knife seat. At this time, the two shear blades will fit together to uniformly cut multiple yarns.
[0022] 2. The limiting grooves on the surfaces of the first guide roller and the second guide roller are in an aligned state. When multiple yarns pass through the middle of the first guide roller and the second guide roller at the same time, a single yarn can be located on the inner side of the limiting groove, so that the limiting groove can separate the multiple yarns to avoid multiple yarns coming from all directions from being entangled together.
[0023] 3. It is convenient to quickly disassemble and assemble the shear blades. The two shear blades are inserted into the inner side of the T-shaped slide groove using the T-shaped handle. Then the positioning pin can be used to penetrate the through hole in the middle of the lug so that the positioning pin can be limited on both sides of the upper and lower blade seats. At this time, the T-shaped handle cannot fall by itself, nor can it move left and right to escape from the T-shaped slide groove. When disassembly is required, just pull out the positioning pin and then pull the T-shaped handle out of the T-shaped slide groove. It is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

When it is necessary to shear the yarn, the rotating shaft 5 is used to drive the driving gear 4 to rotate (the rotating shaft 5 can be driven by a motor or other equipment, or it can be rotated manually. This application is not limited and it can be set according to needs). When the driving gear 4 rotates, it can drive the first adjusting component 2 to move upward, and the second adjusting component 3 to move downward.
