[0066] like Figures 1-12 As shown, a non-woven pillowcase production device includes a feeding device 1, a first folding device, a second folding device, a welding device, a cutting device and a finished pillowcase folding device installed in sequence from front to back, and the front to back refers to from the front end of the production line to the back end of the production line; a cloth pulling roller device is installed between the second folding device and the welding device and between the cutting device and the finished pillowcase folding device; a cloth passing roller device and the cloth pulling roller device are provided in sequence from front to back between the first folding device and the second folding device.

[0067] The feeding device 1 includes a horizontally arranged first mounting frame 34, and the first mounting frame 34 is a rectangular frame. Mounting plates 30 are fixed on both sides of the first mounting frame 34, and a support shaft 46 is rotatably connected between the two mounting plates 30. The support shaft 46 is arranged close to the first folding device. Two spaced assembly components are installed on the support shaft 46, and a feeding roller 38 is installed between the two assembly components. One end of the feeding roller 38 is transmission-connected to the first power device 31. The first power device 31 is used to provide power to the feeding roller 38 to facilitate loading.

[0068] The assembly component includes two first assembly plates 44 and a second assembly plate 45 fixed at intervals on the support shaft 46, and a guide rod 35a group is provided between the first assembly plate 44 and the second assembly plate 45. The guide rod 35a group is installed with a mounting block 35, and both ends of the feeding roller 38 are installed on the mounting block 35; a driving shaft 43 is provided between the guide rod 35a group and the support shaft 46, and the two ends of the driving shaft 43 are rotatably connected to the first assembly plate 44 and the second assembly plate 45 respectively, and an inclined telescopic rod 42 is fixed to the bottom of the driving shaft 43. The telescopic rod 42 uses conventional telescopic devices such as a cylinder, an electric push rod and a hydraulic cylinder. The bottom end of the telescopic rod 42 is close to the support shaft 46 and is hinged to the first mounting frame 34. The telescopic rod 42 is telescopic to drive the assembly to rise and fall. The assembly drives the mounting block 35 to rise and fall and changes the direction of the mounting block 35 to facilitate the installation of the feeding roller 38.

[0069] The guide rod 35a group includes two spaced apart guide rods 35a, the two ends of which are respectively fixed on the first assembly plate 44 and the second assembly plate 45, and the mounting block 35 is slidably connected to the two guide rods 35a. The mounting block 35 is respectively provided with a first assembly hole and a second assembly hole that slides with the two guide rods 35a. The guide rods 35a play a guiding role, which facilitates the adjustment of the position of the mounting block 35 and the loading roller 38.

[0070] The mounting block 35 is L-shaped and includes a horizontal portion and a vertical portion. The first assembly hole and the second assembly hole are respectively arranged at the two ends of the horizontal portion. A mounting groove 49 is provided on the front side of the vertical portion. The front side of the vertical portion refers to the side of the vertical portion facing away from the first folding device, that is, the side close to the front end of the production line. First bearings 36 are installed at both ends of the feeding roller 38, and the first bearing 36 is installed in the mounting groove 49; the top of the vertical portion is threadedly connected to the first locking bolt 37, and the bottom of the first locking bolt 37 extends into the mounting groove 49 and is tightened on the outer ring of the first bearing 36. The first locking bolt 37 plays a locking role, locking the first bearing 36 in the mounting groove 49, and then locking the two ends of the feeding roller 38 in the mounting block 35.

[0071] When the non-woven fabric roll on the feeding roller 38 needs to be replaced, the telescopic rod 42 is retracted, and the telescopic rod 42 drives the assembly of the device to rotate downward by pushing the shaft 43. The position of the mounting block 35 is lowered, and the opening of the mounting groove 49 points to the front end of the production line. The first locking bolt 37 is loosened, and the feeding roller 38 slides out of the mounting groove 49 along the horizontal part to facilitate the installation of a new non-woven fabric roll. The new non-woven fabric roll is loaded from one end of the feeding roller 38, and then the non-woven fabric roll is pushed to push the first bearings 36 at both ends of the feeding roller 38 into the mounting groove 49. The first locking bolt 37 is tightened, and the telescopic rod 42 is extended. The telescopic rod 42 drives the assembly to rotate upward by pushing the shaft 43, and the position of the mounting block 35 is raised. The feeding roller 38 is connected to the first power device 31 through transmission. The first power device 31 provides power for the feeding roller 38, which facilitates the rotation of the feeding roller 38 to discharge the material.

[0072] A feeding roller adjustment device for adjusting the position of the feeding roller 38 is installed on one of the assembly components. The feeding roller adjustment device includes an adjusting screw 40 arranged between the two guide rods 35a. The first assembly plate 44 and the second assembly are respectively fixed with a second bearing 39 with a seat. The first assembly plate 44 and the second assembly are respectively provided with a through hole corresponding to the second bearing 39. The mounting block 35 is provided with a threaded hole. The two ends of the adjusting screw 40 are respectively matched with the corresponding second bearing 39. The adjusting screw 40 passes through the through holes of the first assembly plate 44 and the second assembly plate 45 and can rotate along the through holes. The adjusting screw 40 is threadedly matched with the threaded hole.

[0073] The feeding roller adjustment device is used to adjust the horizontal position of the feeding roller 38. When the non-woven fabric needs to be symmetrically folded by the first folding device, one side of the non-woven fabric is aligned with the other side of the non-woven fabric and folded. The center of the feeding roller 38 corresponds to the center of the first folding device, and the center planes of the two coincide. When the center of the feeding roller 38 deviates from the center of the first folding device, the first folding device folds the non-woven fabric asymmetrically. In this embodiment, the first folding device folds the non-woven fabric asymmetrically to facilitate the formation of an opening on the back of the pillowcase for loading the pillow core.

[0074] The first assembly plate 44 is disposed outside the second assembly plate 45 . The outer end of the adjusting screw 40 extends outside the first assembly plate 44 and fixes the hand wheel 41 to facilitate the rotation of the adjusting screw 40 .

[0075] When it is necessary to adjust the position of the feeding roller 38 relative to the center of the first folding device according to the folding requirements, the hand wheel 41 is turned, and the hand wheel 41 drives the adjusting screw 40 to rotate. The adjusting screw 40 is threadedly connected to the mounting block 35. The rotation of the adjusting screw 40 is converted into horizontal movement of the mounting block 35. The mounting block 35 drives the feeding roller 38 to move to the appropriate position. During the movement of the mounting block 35 along the adjusting screw 40, the mounting block 35 slides along the guide rod 35a.

[0076] The feeding roller 38 is a cylinder shaft, and an air filling port is provided at the end of the cylinder shaft to facilitate the inflation of the cylinder shaft. After a new non-woven fabric roll is installed on the feeding roller 38, the cylinder shaft is inflated, and the air tube at the position where the cylinder shaft is installed in the non-woven fabric roll expands and presses against the inner wall of the non-woven fabric roll to prevent the non-woven fabric roll from falling out; the first power device 31 is an automatic tension controller. When the automatic tension controller provides power to the feeding roller 38, it is convenient to adjust the speed of the feeding roller 38 according to the tension of the non-woven fabric, so that the non-woven fabric maintains a relatively constant tension during the unwinding process. The power device 31 is fixed to one of the assembly components. A driving gear 32 is installed at the output end of the first power device 31. A driven gear 33 is installed at the end of the loading roller 38 close to the first power device 31. The driven gear 33 is engaged with the driving gear 32. The first power device 31 transmits power to the loading roller 38 through the engagement of the driving gear 32 with the driven gear 33.
