Description

Technical Field

[0001] The present invention relates to the technical field of spinning packaging equipment, and in particular provides a rapid detection and film sleeving packaging equipment for cheese yarns in a spinning mill. Background Art

[0002] The cheese yarn film sleeving packaging equipment is a special equipment for automatically packaging cheese yarns in the textile industry, aiming to improve packaging efficiency, reduce labor costs and ensure packaging quality. The working principle of cheese yarn film sleeving packaging: automatically convey the cheese yarn to the packaging position, accurately sleeve the film on the cheese yarn, fix the film through heat sealing technology, cut the film after sleeving, and remove and stack the packaged cheese yarn.

[0003] In the existing film sleeving packaging process, since the film cutting requires a fixed space and is in a linear layout, when the previous cheese yarn is sleeved and packaged, the waiting position of the next cheese yarn is at a long distance from the film sleeving position, increasing the packaging time and reducing the efficiency; at the same time, the traditional equipment relies on the heat shrinkage process and needs to reserve extra film materials (usually 15%-20% more) during cutting and heating to compensate for the shrinkage amount. Moreover, due to poor tension control during cutting, the film is prone to wrinkles or breakage, and the waste film rate is as high as 5%-8%. In addition, the variety of cheese yarns is not verified before film sleeving, resulting in low accuracy. Summary of the Invention

Heating mounting sliders 531 protrude from the four corners of the outer wall of the heating conveyor 53. The four heating mounting sliders 531 are respectively slidably installed at the bottoms of the four mounting vertical sliding columns 521. A heating connecting rod 532 protrudes from one end of each heating mounting slider 531. The tops of the four heating straight racks 55 are respectively connected to the bottoms of the four heating connecting rods 532.

Cutting mounting sliders 541 protrude from the four corners of the outer wall of the cutter 54. The four cutting mounting sliders 541 are respectively slidably installed at the tops of the four mounting vertical sliding columns 521.

The tops of the four cutting straight racks 56 are respectively connected to the bottoms of the four cutting connecting rods 542. And the four cutting straight racks 56 are respectively meshed and connected with the four cutting gears 511.

[0038] On both sides of the bottom of the heating conveyor 53 and one end adjacent to the film placing vertical frame 12, a plurality of cutting springs 533 are respectively arranged. A U-shaped buffer cutting seat 534 is arranged at the tops of the plurality of cutting springs 533; A first hot cutting head 543 and a second hot cutting head 544 are arranged on the cutter 54. The first hot cutting head 543 is arranged on the outside of the cutter 54. The second hot cutting head 544 is arranged at one end of the cutter 54 adjacent to the film placing vertical frame 12. And an elastic clamping plate 545 is arranged at the bottom of the second hot cutting head 544. The elastic clamping plate 545 is arranged opposite to the inclined clamping plate 412.

[0039] For example, in an embodiment: The output end of the cheese yarn production line is arranged opposite to the inner side of the end of the adjustment feeding assembly 30 away from the cutting vertical frame 13. The return end of the cheese yarn re-selection conveyor belt is arranged opposite to the outer side of the end of the adjustment feeding assembly 30 away from the cutting vertical frame 13. A film winding device 60 is arranged on the outside of the chassis 11 adjacent to one end of the cutting vertical frame 13.

[0040] The folded film is a heat-shrinkable film.

[0041] The quick inspection head 343 is used to detect the color of the cheese yarn and the hairiness of the surface yarn. The quick inspection head 343 is electrically connected to the adjustment motor 345 and the feeding drive motor 35. The preheating abutment plate 41 and the vertical heat conducting plate 411 are both made of heat conducting materials. The preheating floating roller 434 is internally provided with heating wires, and a temperature sensor is arranged on the floating mounting vertical plate 431. The temperature sensor is used to monitor the temperatures on the outer surfaces of the two preheating floating rollers 434 and the two temperature expanding discs 435 to ensure that their temperatures are lower than the shrinkage temperature (Ts) of the folded film.

[0042] For example, in an embodiment: When the bottom end of the folded film is pulled out from the film dispenser 20 before sheathing the film, and is guided by the film feeding reversing roller 121 to move to the adjusting feeding assembly 30, and the folded film is opened, and the top and bottom of the folded film are turned over, and are turned over and reversed by the end of the upper triangular plate 428 away from the cutting vertical frame 13 and the end of the lower triangular plate 429 away from the cutting vertical frame 13, and the inner wall of the middle part of the folded film is attached to the vertical heat conducting plate 411, and then it is sent to the cutting and heating assembly 50 in parallel and passes through between the cutter 54 and the heating conveyor 53 and is wound on the film winding device 60.

[0043] When sheathing the film is required, the production line of the cheese yarn feeds the cheese yarn into the cheese yarn conveyor belt, starts the feeding drive motor 35, and then drives the cheese yarn conveyor belt to convey. Subsequently, the pushing cylinder 341 will start, and then drive the pushing plate 342 to move inwards, pushing the cheese yarn to move directionally inside until the cheese yarn is arranged inside the folded film and is sent onto the heating conveyor 53 of the cutting and heating assembly 50. Then, two synchronous motors are started to drive the two cutting adjustment rotating shafts 51 to rotate, and then the four cutting gears 511 will follow to rotate, and then the four heating straight racks 55 and the four cutting straight racks 56 will follow to move. The four heating straight racks 55 will move upwards, causing the four heating connecting rods 532 and the heating mounting sliders 531 to follow upwards, causing the heating conveyor 53 to follow upwards, and the four cutting straight racks 56 will move downwards, and then the four cutting connecting rods 542 and the four cutting mounting sliders 541 will follow downwards until the first hot cutting knife head 543 and the second hot cutting knife head 544 press the folded film and continue to move until they abut against the top surface of the buffer cutting seat 534 and compress a plurality of cutting springs 533. At this time, the first hot cutting knife head 543 and the second hot cutting knife head 544 will start, causing the folded film to melt and complete the packaging of a single cheese yarn.

[0044] And when the second hot cutting head 544 moves downward to abut against the top surface of the buffer cutting seat 534, and the bottom end of the elastic clamping plate 545 abuts against the inclined clamping plate 412, the film feeder 20 will pause, thereby fastening the feeding end of the folded film. At the same time, the stretching motor and the clamping motor 445 will start. The clamping motor 445 will drive the clamping rod 446 to move upward to clamp the upper part of the folded film. At the same time, the stretching motor will drive the middle threaded rod 425 to rotate, so that the upper triangular cross bar 427 and the upper triangular plate 428 will move upward, thereby tightening and stretching the upper part of the folded film. And, the two floating adjustment motors 433 will start synchronously, so that the preheating floating roller 434 and the temperature expansion plate 435 will move up and down, so that the outer wall of the preheating floating roller 434 will abut against the outer wall of the folded film to soften and stretch the folded film. At the same time, it will also cause the lower adjustment cross bar 426 to move downward, so that the inclined pressing piece 449 will move downward accordingly. Since one end of the lower triangular plate 429 away from the cutting vertical frame 13 is made of elastic material, and the bottom end of the inclined pressing piece 449 abuts against the top surface of the pushing piece 448, the lower triangular plate 429 will be pushed to expand the lower part of the folded film. In addition, when the preheating floating roller 434 and the temperature expansion plate 435 move up and down, the outside of the temperature expansion plate 435 will abut against the middle part of the outer wall of the folded film, thereby synchronously softening the middle part of the outer wall of the folded film. And because the inner wall of the middle part of the folded film is attached to the vertical heat conducting plate 411, the temperature on the temperature expansion plate 435 will be evenly dispersed onto the vertical heat conducting plate 411. Thereby preheating, softening, expanding and stretching the folded film between the adjusting feeding assembly 30 and the cutting and heating assembly 50, thereby ensuring that the folded film is uniform and flat during subsequent cutting and packaging, preventing wrinkles or breakage, and at the same time reducing the thickness of the folded film, and thus the amount of redundant film material required for cutting and heating. In addition, because the folded film is expanded and stretched, the next package of cheese to be cut and packaged can continue to move "forward" on the cheese conveyor belt during the above actions, reducing the distance between the waiting position and the film sleeving position and improving the cutting efficiency.

[0045] When the cutting and packaging of the folded film of the cheese on the cutting and heating assembly 50 is completed, the heating conveyor 53 will start to send the packaged cheese to the heat shrinker to perform heat shrinkage on the folded film. And, the stretching motor and the clamping motor 445 will reverse and reset, and the film feeder 20 will start to convey the folded film.

[0046] For example, in one embodiment: when there are color differences in the cheese yarn output from the production line to the cheese yarn conveyor belt, the uniformity does not meet the requirements, or the hairiness of the surface yarn is dispersed or burrs appear, etc., the quick inspection head 343 will quickly identify this situation and send a signal to the adjustment motor 345 and the feeding drive motor 35, so that the adjustment motor 345 is started to drive the adjustment screw rod 344 to rotate, so that the feeding moving frame 33, the feeding fixed frame body 31, the preheating abutting plate 41, and the stretching triangular plate element 42 will slide outward along the two feeding installation cross rails 32, so that the cheese yarn therein will move along, until the cheese yarn is oppositely arranged relative to the return end of the cheese yarn return conveyor belt. At the same time, it will also cause the feeding drive motor 35 to run in reverse, and then move the cheese yarn conveyor belt in the reverse direction to return the unqualified cheese yarn to the cheese yarn return conveyor belt, completing the rapid detection and return sorting of the cheese yarn.
