[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0033] Example
[0034] like Figure 1-9As shown, a fully automatic linear density detection device includes a frame 1, an adjustable tension control mechanism 2 installed on one side above the frame 1, a yarn feeding mechanism 3 installed on the frame 1 and cooperating with the adjustable tension control mechanism 2, a yarn winding mechanism 4 installed on the other side above the frame 1 and cooperating with the yarn feeding mechanism 3, a waste yarn collection suction pipe 5 installed on the outside of the yarn winding mechanism 4, a weighing mechanism 6 installed inside the frame 1 and located between the yarn feeding mechanism 3 and the yarn winding mechanism 4, and a yarn suction mechanism 7 fixed on the weighing mechanism 6 and cooperating with the weighing mechanism 6.
[0035] The adjustable tension control mechanism 2 includes a first lifting cylinder 21 fixedly installed on the frame 1, a transverse moving cylinder 22 fixedly installed above the first lifting cylinder 21, a plurality of yarn guide hooks 23 equidistantly installed on the output end of the transverse moving cylinder 22, a strip plate 24 fixedly installed above the first lifting cylinder 21, and tension adjustment components 25 equidistantly installed on the strip plate 24, with the same number as the yarn guide hooks 23.
[0036] An L-shaped bracket 211 is fixedly installed on the inner side of the first lifting cylinder 21 by bolts, which facilitates the installation of the first lifting cylinder 21 and the frame 1.
[0037] The output end of the first lifting cylinder 21 is provided with a top plate 212. Specifically, the top plate 212 can support and fix the transverse moving cylinder 22 and the tension adjustment component 25.
[0038] The output end of the transverse moving cylinder 22 is fixedly mounted with a yarn guide hook assembly plate 221 by bolts. Specifically, yarn guide hooks 23 can be inserted at equal intervals, and the yarn guide hooks 23 can guide the yarn into the yarn feeding mechanism 3 for processing.
[0039] The tension adjustment assembly 25 includes a base 251 that abuts against the top plate 212 and is fixed with bolts, a yarn guide plate 252 that is fixed to the base 251 with bolts, a pressure sensor 253 installed inside the base 251, and a second lifting cylinder 254 fixedly installed above the base 251. Specifically, the first lifting cylinder 21 and the second lifting cylinder 254 operate simultaneously. After the yarn is centered by the yarn guide plate 252, it is pressed down by the yarn guide plate 252. The pressure sensor 263 presses down on the yarn and will provide feedback on the pressure value. During the yarn winding process, the pressure value is controlled by the pressure of the second lifting cylinder 254. The second lifting cylinder 254 is connected to a digital display pressure gauge, which will adjust the pressure according to the pressure value to achieve stable tension control.
[0040] The yarn feeding mechanism 3 includes a yarn feeding and transplanting mold base 31 fixedly installed with the frame 1 and equipped with a drive cylinder, a yarn feeding support plate 32 fixedly installed on the yarn feeding and transplanting mold base 31 and driven to move by the yarn feeding and transplanting mold base 31, a suction tube 33 with a funnel equidistantly installed on the yarn feeding support plate 32, a front yarn cutting cylinder 34 with a knife installed on the yarn feeding support plate 32 and connected to the suction tube 33, a winding tube 35 installed on the yarn feeding support plate 32 and connected to the front yarn cutting cylinder 34 with a knife, and a winding motor 36 installed on the yarn feeding support plate 32 and connected to the winding tube 35 via a belt.
[0041] The yarn winding mechanism 4 includes a yarn winding and transfer mold base 41 fixedly installed with the frame 1 and equipped with a drive cylinder, a yarn winding bracket 42 fixedly installed on the yarn winding and transfer mold base 41 and driven to move by the yarn winding and transfer mold base 41, a winding reel 43 equidistantly installed inside the yarn winding bracket 42, a yarn pushing rod 44 disposed inside the winding reel 43 and fixed to the yarn winding bracket 42 by a micro cylinder, a yarn pressing cylinder 45 installed on the yarn winding bracket 42 and corresponding to the winding reel 43, and a yarn cutting cylinder 46 with a knife installed on the yarn winding bracket 42 and corresponding to the yarn pressing cylinder 45.
[0042] Specifically, the yarn end is sucked up through the funnel of the suction tube 33, and the yarn passes through the suction tube 33, the front yarn-cutting cylinder 34 with a blade, and the winding tube 35.
[0043] The yarn winding tube 35 guides the yarn to the winding reel 43. The yarn pressing cylinder 45 on the winding reel 43 clamps the yarn end. The yarn cutting cylinder 46 with a blade cuts off the excess yarn tail. The waste yarn collection suction tube 5 sucks away the cut yarn tail. Then, the yarn guiding and transfer mold base 31 drives the yarn guiding plate 32 to move the yarn winding tube 35 to the vicinity of the winding reel 43. The yarn winding motor 36 drives the yarn winding tube 35 to rotate, winding the yarn onto the winding reel 43. During this process, the yarn winding reel 43 moves back and forth through the yarn winding transfer mold base 41, driving the yarn winding bracket 42 to make the yarn on the winding reel 43 evenly wound. After a certain number of turns, the yarn cutting cylinder 34 with a blade cuts the yarn. After cutting, the yarn winding tube 35 winds two more turns to wind the remaining yarn tail onto the winding reel 43. Finally, the push rod 44 pushes out the wound yarn ball, causing it to fall into the weighing mechanism 6.
[0044] The weighing mechanism 6 includes a weighing frame 61, a weighing balance 62 equidistantly mounted on the weighing frame 61, a hopper 63 located above the weighing balance 62 and supported by the weighing frame 61, and a balance cover 64 mounted in front of the weighing frame 61 and controlled by a telescopic cylinder.
[0045] The yarn suction mechanism 7 includes a guide rail 71, a traveling trolley 72 mounted on the guide rail 71, a forward / backward cylinder 73 mounted on the traveling trolley 72, and a yarn suction elbow 74 mounted on the output end of the forward / backward cylinder 73. Specifically, the guide rail 71 is fixedly mounted on the side of the weighing frame 61, and the yarn suction elbow 74 is flexibly controlled by the forward / backward cylinder 73 to move to the position between the weighing balance 62 and the feed hopper 63, so that the yarn suction elbow 74 can easily suck away the wound yarn.
[0046] It should be further explained that after the wound yarn ball is pushed out by the yarn pusher 44, it falls into the feed hopper 63 and then falls precisely onto the weighing balance 62. At this time, the balance cover 64 moves above the weighing balance 62 through the telescopic cylinder to form a sealed environment. After the weighing is completed, the balance cover 64 is removed, and the yarn suction mechanism 7 starts to move and suck up the yarn ball.
[0047] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, shall fall within the scope of protection of this utility model.
