Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of yarn winding, and in particular to a device for cutting and winding PVDF polymer composite yarn. Background Technology
[0002] Yarn has irregular shapes and different types of structures. By arranging textile fibers in a regular manner, various fabrics on the market are formed. In the production process of PVDF polymer composite yarn, the yarn is generally cut by a cutting device and then wound onto a yarn winding wheel by hand. Moreover, during the production process, the yarn needs to be wound up by a winding device to facilitate subsequent processing of the yarn.
[0003] Existing PVDF polymer composite yarn cutting and winding devices fail to clamp and compress the cut composite yarn before cutting, making it difficult for the cutting blade to cut the composite yarn and for pulling out the cut composite yarn. Furthermore, the tension of the composite yarn cannot be easily adjusted during winding, and overly loose composite yarn is neither easy to cut nor easy to wind up neatly.
[0004] Therefore, we designed a PVDF polymer composite yarn cutting and winding device to meet the needs of practical applications. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a PVDF polymer composite yarn cutting and winding device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a PVDF polymer composite yarn cutting and winding device, including a base, a body mounted on one top end of the base, a first guide roller mounted on one top end of the body, a second guide roller mounted on one side top end of the body, a height adjustment mechanism between the second guide roller and the base, a support plate mounted on the outer side of the second guide roller, yarn perforations on the surface of the support plate, a pressing mechanism mounted inside the yarn perforations, a cutting mechanism between the two support plates, and a winding roller mounted on one end of the base;
[0008] The clamping mechanism includes a clamping plate and a clamping rod. The bottom end of the clamping rod is slidably inserted into the yarn through hole, and the clamping plate is fixed to the bottom end of the clamping rod.
[0009] The cutting mechanism includes a cutting blade, and the top of the base has a movable groove. The bottom end of the cutting blade is vertically inserted into the movable groove and is located between the two yarn through holes.
[0010] In detail, the height adjustment mechanism includes an adjustment block and an adjustment rod. A first mounting plate is fixed to the top of the base. The first mounting plate is close to the body and has an adjustment groove on its surface. A first guide hole is formed at the top of the adjustment groove.
[0011] In detail, the adjusting rod is fixed to the top of the adjusting block, the second guide roller is rotatably installed between the two adjusting blocks, the adjusting block is slidably inserted into the adjusting groove, the top of the adjusting rod slides through the first guide hole, and a nut is connected to its surface.
[0012] In detail, the support plate is set vertically, the yarn perforation is set horizontally, and a second guide hole is opened at its top.
[0013] In detail, the clamping rod slides vertically through the second guide hole, the clamping plate has an arc-shaped structure with its bottom end protruding downwards, a connecting plate is fixed to the top of several clamping rods, and a first electric push rod is installed between the bottom end of the connecting plate and the top end of the support plate.
[0014] In detail, the moving slot is a long strip structure. A second mounting plate is fixed on one side of the base and at the outer end of the moving slot. A second electric push rod is horizontally mounted on the top of the second mounting plate. A mounting frame is fixed to the inner end of the second electric push rod. The cutting blade is rotatably mounted inside the mounting frame. A first motor is mounted on one side of the frame. The first motor is fixed on the outer side of the mounting frame. The mounting frame is slidably mounted on the top of the base.
[0015] In detail, a third mounting plate is fixed to the top of the base, the take-up roller is rotatably mounted between the two third mounting plates and is horizontally positioned above the yarn through hole, and a second motor is mounted on one end of the take-up roller, the second motor being fixedly mounted on the outside of the third mounting plate.
[0016] Core function: The first guide roller and the second guide roller are respectively set on the upper and lower sides of the machine body. The second guide roller is mounted on the base through the adjusting block and the first mounting plate to guide the composite yarn.
[0017] In the first mounting plate, the adjusting block and adjusting rod are moved up and down along the adjusting groove and the first guide hole to adjust the height of the second guide roller, thereby adjusting the tension of the composite yarn, which facilitates the subsequent cutting and winding of the yarn.
[0018] Two support plates are set on the base, and yarn through holes are provided on the surface of the support plates for passing through the composite yarn;
[0019] Inside the yarn perforation, the pressing rod drives the pressing plate to move, and the first electric push rod drives the connecting plate to move several pressing rods up and down. Therefore, before the cutting knife cuts the composite yarn, the second electric push rod drives the pressing rod and pressing plate to descend, and the pressing plate presses the composite yarn to the bottom end of the yarn perforation, thereby pressing the composite yarn on both sides of the cutting knife.
[0020] A cutting blade is installed between two support plates. The second electric push rod drives the mounting frame and the cutting blade to move along the moving groove. At the same time, the first motor drives the cutting blade to rotate, so that during the cutting rotation, it moves along the moving groove and cuts several composite yarns.
[0021] After several composite yarns are cut by a cutting knife, the composite yarns on both sides of the cut are pressed by a pressure plate. The first electric push rod on the side near the take-up roller rises, causing the pressure plate to release the composite yarns, so that the take-up roller can take up the composite yarns. The composite yarns near the second guide roller retain the yarn ends, making it easy to pull them outwards.
[0022] The design scheme proposed in this utility model has the following beneficial effects in application:
[0023] 1. Press the composite yarn tightly before cutting to maintain the ease of cutting the composite yarn, and press the cut composite yarn tightly to make it easier to pull out the cut composite yarn.
[0024] 2. Adjust the height of the second guide roller by adjusting the adjusting block and adjusting rod, thereby adjusting the tension of the composite yarn, which facilitates the cutting of the composite yarn by the cutting knife and also facilitates the neat winding of the composite yarn.
