Description

Technical Field

[0001] The utility model relates to the technical field of tufted carpet processing, in particular to a yarn cutting device for a numerically controlled tufted carpet machine that is convenient for installation. Background Technique

[0002] A tufted carpet machine mainly pierces yarns into a base cloth woven from non-woven fabric through a series of needles and forms pile loops on the top of the base cloth, thereby constituting the surface of the carpet;

[0003] During the processing of a tufted carpet machine, the cutting of yarns is an important step. Especially when making cut-pile carpets, it is necessary to cut the pile loops to form a flat carpet surface. In addition, even when making loop-pile carpets, if the yarns are too long or not cut at the appropriate position, it may cause problems such as an uneven back of the carpet and many loose ends, affecting the beauty and durability of the carpet.

[0004] In order to overcome the above defects, there is a yarn cutting device for a numerically controlled tufted carpet machine in the prior art 1 (publication number: CN216473896U, Chinese patent with a publication date of May 10, 2022). The telescopic rod of the scissors cylinder is extended. At this time, the position of the cylinder joint moves. Since the two ends of the scissors connecting rod are respectively rotationally connected to the cylinder joint and the scissors, and the scissors are rotationally connected to the scissors cylinder fixing plate through a fixed rotating shaft, the movement of the cylinder joint drives the two scissors connecting rods to expand outwards, thereby causing the scissors to open. Then, the extending cylinder is used to drive the scissors cylinder fixing plate to extend, so that the scissors extend. The wool yarn to be cut is placed in the open scissors. Then, the scissors cylinder is contracted, so that the scissors are closed, thereby performing a cutting operation on the wool yarn. It effectively realizes that when the needle nozzle leaves the base cloth during the processing of loop-pile carpets by the numerically controlled tufted carpet machine, the yarn is automatically cut close to the base cloth to meet the process requirements, so that the back of the carpet is flat, the loose ends are reduced, and the yarn and glue are saved.

[0005] There is also a yarn cutting device in the prior art 2 (publication number: CN115874340A, Chinese patent with a publication date of March 31, 2023). During the operation of the loom, when the reed swings for beating-up, at this time, the reed controls the weft cutter to swing synchronously in the opposite direction through the first transmission unit and the second transmission unit to cut the weft yarn introduced and clamped in the weft guide opening. It does not require additional electrical control equipment to control the accurate cutting of the weft cutter. Its control method is relatively stable and not prone to failures. When the reed swings for beating-up, the first rotating shaft in the reed drives the input bevel gear to rotate. The input bevel gear drives the transmission rod to rotate through the first transmission bevel gear. The transmission rod drives the first belt pulley to rotate through the second transmission bevel gear and the output bevel gear. The first belt pulley drives the second belt pulley to rotate through the transmission belt to control the weft cutter to swing synchronously in the opposite direction to cut the weft yarn introduced and clamped in the weft guide opening.

[0006] Although the prior art 1 and the prior art 2 can cut the yarn, the steps are rather cumbersome during the installation of their devices. When the user needs to replace the cutting device, the replacement is inconvenient. At the same time, when the cutting device cuts the yarn, some fluff waste will be generated from the yarn, and the waste accumulates at the blade position, which easily affects the subsequent cutting operation.

[0007] Therefore, we propose a yarn cutting device for a numerically controlled tufting carpet machine that is easy to install to solve the above-mentioned problems. Summary of the Utility Model

[0008] The purpose of the present utility model is to provide a yarn cutting device for a numerically controlled tufting carpet machine that is easy to install, so as to solve the problems mentioned in the above background technology that when the user needs to replace the cutting device, the replacement is inconvenient, and at the same time, when the cutting device cuts the yarn, some fluff waste will be generated from the yarn, and the waste accumulates at the blade position, which easily affects the subsequent cutting operation.

[0009] To achieve the above purpose, the present utility model provides the following technical solution: A yarn cutting device for a numerically controlled tufting carpet machine that is easy to install, including an installation head, the lower surface of the installation head is fixedly connected with a fixing plate, and the center of the lower surface of the fixing plate is fixedly connected with a telescopic rod, and the output end of the telescopic rod is fixedly connected with a connecting plate, and at the same time, a cutting knife is fixedly connected to the lower side of the connecting plate;

[0011] Activity groove, the activity groove is opened on the side of the lower surface of the fixing plate, and two groups of air bags are fixedly connected to the inner side of the activity groove, and a dust cleaning mechanism for preventing interference from cutting scraps is arranged between the inner sides of the two groups of air bags and the side of the connecting plate.

[0012] Further, the auxiliary mechanism includes an auxiliary elastic piece, the auxiliary elastic piece is fixedly connected to the inner side of the first elastic piece, a screw rod is threadedly connected to the side of the installation head, and a handle is fixedly connected to the outer side of the screw rod.

[0013] Further, the first elastic piece is arranged in a zigzag structure, and the first elastic piece extends to the outside of the installation head, and the first elastic piece is symmetrically arranged about the center point of the installation head.

[0014] Further, the auxiliary elastic piece is arranged at the inner side end of the first elastic piece, and the auxiliary elastic piece protrudes towards the inside of the installation head.

[0015] Furthermore, the dust cleaning mechanism includes a limiting rod fixedly connected to the lower surface of the fixed plate. A slider is nested on the outer side of the limiting rod, and a rotating rod is hinged to the outer side of the slider. The other end of the rotating rod is hinged to the side of the connecting plate. An extrusion plate is fixedly connected to the inner side of the slider, and the extrusion plate is fixedly connected to the inner sides of two air bags. A blowing port is provided on the air bag.

[0016] Furthermore, the limiting rod is arranged at the central position of the moving groove. The extrusion plate drives the rotating rod and the slider to form a rotating structure through a telescopic rod, and the slider forms a rotating structure with the limiting rod through the rotating rod.

[0017] Furthermore, the extrusion plate is nested inside the moving groove, and the extrusion plate forms a rotating structure with the moving groove through the slider.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The user can snap the device onto the carpet machine through the mounting head. At the same time, the anti-slip pad can increase the resistance between the mounting head and the carpet machine during installation, reducing the occurrence of the device slipping down during installation.

[0020] 2. Through the elasticity of the first elastic sheet itself, the contact between the mounting head and the carpet machine can be made more firm.

[0022] 4. When the yarn needs to be cut, the telescopic rod can be started. At this time, the telescopic rod synchronously drives the connecting plate to move, causing the connecting plate to drive the cutting knife to cut the yarn. During the movement of the connecting plate, the two ends of the rotating rod will be synchronously driven to rotate. When the rotating rod rotates, it will drive the slider to slide along the limiting rod. At this time, the limiting rod will limit the slider, further improving the stability of the slider during movement and enabling the connecting plate to stably drive the cutting knife to cut the yarn.

[0023] 5. When the slider slides, it will synchronously drive the extrusion plate to slide inside the moving groove, thereby squeezing the two air bags on both sides. The air bag is squeezed, and the gas inside it will be discharged outward through the blowing port, thereby cleaning the lint adhered to the cutting knife and reducing the possibility of lint accumulating on the cutting knife and affecting the subsequent cutting effect of the cutting knife.
