Description

Technical Field

[0001] This invention belongs to the field of towel fabric production technology, specifically relating to a material feeding adjustment device for towel fabric production. Background Technology

[0002] The terry loop fabric of terry cloth is composed of plain knit loops and loops with elongated sinker arcs. It is generally woven with two yarns: one yarn weaves the ground knit and the other yarn weaves the loops. Terry cloth can be used to produce bath towels, hand towels, bathrobes, floor mats, and pillowcases. During the production process, terry cloth needs to be slit into the required size using a slitting machine, and then cut into blanks using a blanking machine.

[0003] In existing unloading equipment, the slit towels are directly conveyed to the collection box via a conveyor during the unloading process. Due to the weight of the towels falling, they are piled up haphazardly in the collection box, which is not conducive to subsequent packaging and collection. When carrying out the subsequent packaging process, manual stacking is required, which is time-consuming, labor-intensive, and has low work efficiency. In addition, during the slit process, the cutter is used to press down directly to slit the towels, and the sides of the towels are not pressed and fixed. The cuts are not uniform, and the quality of the slit towels is poor. Summary of the Invention

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example: Please refer to Figure 1 and Figure 2 A material feeding adjustment device for towel fabric production includes a frame 1, which provides a mounting base for the equipment on it. Two pressing and conveying mechanisms 3 for towel fabric conveying are symmetrically arranged on the top of the frame 1. An electrical control box 6 is arranged on the front side of the frame 1. A slitting mechanism 4 is arranged on the top right side of the frame 1. A material feeding mechanism 5 for material feeding and stacking is arranged on the right side of the slitting mechanism 4. A first guide roller 2 is rotatably installed on the top left side of the frame 1. A second guide roller 9 is rotatably installed in the middle of the top of the frame 1. Two servo motors 8 are fixedly installed on the rear side of the frame 1. A connecting shaft is fixedly installed on the rear side of the fixed roller 36. The connecting shaft is connected to the output end of the servo motor 8 through a sprocket and chain. A roller conveyor 7 is arranged on the top right side of the frame 1.

[0031] In use, the pressing and conveying mechanism 3 is used to press and convey the fabric, the electrical control box 6 is used to open and close the equipment and control the operation of the equipment to ensure the smooth conveying and cutting of the fabric, the slitting mechanism 4 is used to realize the automatic slitting of the towel fabric, the second guide roller 9 is used to realize the guiding and conveying of the fabric, the servo motor 8 is used to drive the pressing and conveying mechanism 3, and the roller conveyor 7 is used to convey the slitting material to the unloading mechanism 5.

[0032] Please see Figure 1The pressing and conveying mechanism 3 includes mounting frames 32 symmetrically fixedly installed on the top of the frame 1. Movable blocks 33 are movably installed on the mounting frames 32. Fixed rollers 36 are rotatably installed between the two mounting frames 32 at the bottom. Movable blocks 33 are movably installed on both mounting frames 32. Movable rollers 35 are rotatably installed between the two movable blocks 33. The top of the two movable blocks 33 are fixedly connected to a linkage plate 34. A cylinder 31 is fixedly installed on the top of one of the mounting frames 32. The cylinder 31 is connected to the output end of an external air pump (not shown in the figure). The air pump is existing technology. The output end of the cylinder 31 moves through the mounting frame 32 and is fixedly connected to the top of the movable block 33. A guide rod 37 that slides through the other movable block 33 is fixedly installed on the other mounting frame 32.

[0033] In use, the towel to be processed is passed around the first guide roller 2, and then guided by the second guide roller 9. The fabric is then placed between the movable roller 35 and the fixed roller 36 on the pressing and conveying mechanism 3. At this time, the first cylinder 31 is activated, and the output end of the first cylinder 31 extends, driving the movable block 33 and the linkage plate 34 on it to move downward. Simultaneously, it drives another movable block 33 to move downward, and at the same time, it drives the movable roller 35 to move downward. The movable roller 35 and the fixed roller 36 are used to clamp and stretch the towel. At this time, the servo motor 8 is activated, and the output end of the servo motor 8 drives the fixed roller 36 to rotate. The rotation of the fixed roller 36 drives the towel to continue to be conveyed.

[0034] Please see Figure 2 and Figure 4 The slitting mechanism 4 includes a gantry frame 41 fixedly installed on the frame 1. Multiple fixed frames 44 are fixedly connected to the top center of the gantry frame 41. A third cylinder 42 is fixedly installed on the fixed frame 44 in the middle. A second guide rod 43 is movably passed through the fixed frames 44 on both sides. Limit blocks 45 are fixedly installed at the bottom of the output ends of the second guide rod 43 and the third cylinder 42. A pre-pressing assembly 46 is provided at the bottom of the multiple limit blocks 45. The third cylinder 42 is connected to the output end of an external air pump, which is existing technology.

[0035] Please see Figure 2 , Figure 4 and Figure 5The pre-pressing assembly 46 includes a knife holder 466 fixedly connected to the bottom of the limiting block 45. A cutter is fixedly installed at the bottom of the knife holder 466. Multiple fixed arms 461 are fixedly installed on the left and right sides of the knife holder 466. A top plate 462 is fixedly installed at the bottom of the multiple fixed arms 461 located on the same side. Multiple movable rods 464 are movably passed through the top plate 462. A pressing plate 463 is fixedly installed at the bottom of the multiple movable rods 464. A first spring 465 is sleeved on the outside of the movable rod 464. The first spring 465 is fixedly installed between the top plate 462 and the pressing plate 463. A stop block that fits against the top of the top plate 462 is fixedly installed on the top of the movable rod 464.

[0036] In use, the electrical control box 6 is used to transport the material by the pressing and conveying mechanism 3, realizing the intermittent fixed-length conveying of the towel. The intermittent fixed-length conveying is the existing technology. The towel is transported to the bottom of the slitting mechanism 4. At this time, the third cylinder 42 is started. The output end of the third cylinder 42 extends, driving the limit block 45 and the knife holder 466 on it to move downward. Simultaneously, the cutter moves downward, driving the fixed arm 461 and the top plate 462 on it to move downward. Simultaneously, the movable rod 464 and the pressing plate 463 on it move downward. The pressing plate 463 is used to press and fix the towel. During the pressing process, the first spring 465 is compressed. As the cutter presses down, the first spring 465 is compressed tighter and tighter, ensuring the stable pressing of the towel. While maintaining the compressed state, the cutter is used to cut, which helps to ensure the neatness of the cut and the good cutting quality. After the cutting is completed, the roller conveyor 7 is used to transport the slid fabric to the unloading mechanism 5.

[0037] Please see Figure 2 , Figure 6 and Figure 7 The material unloading mechanism 5 includes a material unloading collection box 51 located on the right side of the cutting mechanism 4. The material unloading collection box 51 is equipped with a lifting component 55. A second cylinder 53 is fixedly installed on the top rear side of the material unloading collection box 51. Two fixed blocks are symmetrically installed on the front side of the material unloading collection box 51. A fixed shaft 57 is fixedly installed between the two fixed blocks. A flip door 56 is rotatably installed on the fixed shaft 57. A torsion spring 58 is sleeved in the middle of the fixed shaft 57. The two ends of the torsion spring 58 are fixedly installed on the flip door 56 and the material unloading collection box 51, respectively.

[0038] Please see Figure 2 , Figure 6 , Figure 7 and Figure 8The lifting assembly 55 includes fixed sleeves 553 fixedly connected to the four corners of the bottom surface inside the material collection box 51. Telescopic rods 552 are movably inserted through the fixed sleeves 553. A lifting plate 551 is fixedly connected to the top of multiple telescopic rods 552. The lifting plate 551 is slidably connected inside the material collection box 51. A second baffle 554 is fixedly connected to the bottom of the telescopic rods 552. The second baffle 554 is slidably connected inside the fixed sleeves 553. A second spring 555 is installed inside the fixed sleeves 553. The second spring 555 is fixedly connected between the bottom surface of the fixed sleeve 553 and the second baffle 554. The material collection box 51 is fixedly installed on the top left side. A guide plate 52 is provided to guide the towel cloth and ensure that it falls accurately onto the lifting plate 551. A baffle 54 is fixedly installed on the top right side of the material collection box 51. A contact switch 556 is fixedly installed on the lower middle part of the rear inner wall of the material collection box 51. A through hole is opened in the middle of the rear side of the material collection box 51. The output end of the second cylinder 53 moves through the material collection box 51 and is fixedly connected to a fixing plate 59. The fixing plate 59 is located above the contact switch 556. That is, when the fixing plate 59 presses the contact switch 556, the fixing plate 59 is above the lifting plate 551. The fixing plate 59 is L-shaped, and the horizontal section of the fixing plate 59 moves through the through hole.

[0039] In operation, when the roller conveyor 7 transports the slit towels onto the lifting plate 551, the stacking of the towels causes the lifting plate 551 and its telescopic rod 552 to move downwards, simultaneously causing the second baffle 554 to move downwards and compressing the second spring 555. As the towels are pressed down, the lifting plate 551 gradually moves downwards, achieving simultaneous stacking and downward movement, thus realizing automatic stacking of the towels. This continues until the lifting plate 551 presses the contact switch 556, at which point the contact switch 556 controls the second cylinder 53 to start. The output end of cylinder 53 drives the fixed plate 59 to convey forward. The fixed plate 59 pushes the stacked towels forward. During the pushing process, the horizontal section at the bottom of the fixed plate 59 contacts the top of the lifting plate 551. As it is pushed, the towels squeeze the flip door 56. The flip door 56 rotates around the fixed shaft 57 and then compresses the torsion spring 58. At this time, the fixed plate 59 pushes the stacked towels out from the flip door 56 and then pushes them onto the conveyor belt (not shown in the figure). The conveyor belt transports the towels to the next process, realizing the automatic stacking and conveying of towels.

[0040] It should be noted that, in the use of this material feeding adjustment device for terry cloth production, the terry cloth to be processed is passed around the first guide roller 2, and then guided by the second guide roller 9. The cloth is then placed between the movable roller 35 and the fixed roller 36 on the pressing and conveying mechanism 3. At this time, the first cylinder 31 is activated, and the output end of the first cylinder 31 extends, driving the movable block 33 and the linkage plate 34 on it to move downwards. Simultaneously, it drives another movable block 33 to move downwards, and at the same time, it drives the movable roller 35 to move downwards. The movable roller 35 and the fixed roller 36 are used to clamp and stretch the terry cloth. At this time, the servo motor 8 is activated, and the output end of the servo motor 8 drives the fixed roller 36 to rotate. The rotation of the fixed roller 36 drives the terry cloth to continue to be conveyed. The terry cloth is conveyed to the bottom of the slitting mechanism 4. The cutter in the slitting mechanism 4 is used to pre-press and slit the terry cloth. After the slitting is completed, the roller conveyor 7 is used to convey the slit terry cloth to the material feeding mechanism 5. The material feeding mechanism 5 is used to automatically stack and convey the slit terry cloth.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
