Description

Technical Field

[0001] This utility model relates to the field of linen stacking machine technology, and more specifically, to a linen stacking machine for the laundry industry. Background Technology

[0002] Linen stacking machines are mainly used in large laundry rooms in hotels, hospitals, factories, etc., to stack folded clothes, blankets, quilt covers and other linens.

[0003] Currently used linen stacking machines typically use a first conveyor belt to transfer linens to a second conveyor belt, which then transfers them to a switching platform. The platform is then activated, causing the folded linens to fall onto a third conveyor belt. This process is repeated to stack the linens. However, when the linens are placed on the third conveyor belt, they are in free fall from a considerable height. This can cause the linens to unfurl due to the airflow during free fall, resulting in uneven stacking. Furthermore, the unfurled linens need to be refolded, leading to repetitive work and reduced production efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, this utility model provides a linen stacking machine for the laundry industry, including a base 1, a placement frame 2 fixedly connected to the top of the base 1, a PLC controller 3 fixedly connected to the top of the placement frame 2, two first conveyor rollers 4 rotatably connected inside the placement frame 2, a first conveyor belt 5 rotatably connected to the outside of the first conveyor rollers 4, two second conveyor rollers 6 rotatably connected inside the placement frame 2, a second conveyor belt 7 rotatably connected to the outside of the second conveyor rollers 6, a lifting assembly provided inside the placement frame 2, the lifting assembly including a first motor 8 fixedly connected to the top of the base 1, the first motor 8 electrically connected to the PLC controller 3, a screw 9 fixedly connected to the transmission end of the first motor 8, a first transmission block 10 threadedly connected to the outside of the screw 9, a mounting frame 13 fixedly connected to the outside of the first transmission block 10, two limiting blocks 14 fixedly connected inside the mounting frame 13, the two limiting blocks 14 being arranged opposite to each other, a connecting plate 12 rotatably connected to the top of the screw 9, the connecting plate 12 being fixedly connected to the inside of the placement frame 2, two sliding rods 11 fixedly connected between the connecting plate 12 and the base 1, the sliding rods 11 passing through the first transmission block 10 and slidingly connected.

[0026] The first motor 8 drives the screw 9 to rotate, which in turn drives the first transmission block 10 to move, which in turn drives the mounting frame 13 to move, which in turn drives the switch assembly to move, which in turn drives the linen to move, thereby changing the distance between the linen and the third conveyor belt 36. This reduces the time the linen spends in free fall, reduces the probability of the linen being unfolded, reduces the possibility of uneven stacking, reduces the possibility of rework of the linen, and thus improves work efficiency.

[0027] The mounting frame 13 is equipped with a transmission assembly, which includes a second motor 15 fixedly connected inside the mounting frame 13. The second motor 15 is electrically connected to the PLC controller 3. The transmission end of the second motor 15 is fixedly connected to a first transmission rod 16. There are two first transmission rods 16. The two ends of the second first transmission rod 16 are rotatably connected to the inside of the mounting frame 13. The outer side of the first first transmission rod 16 is fixedly connected to a first gear 17. There are two first gears 17, and the two first gears 17 mesh with each other.

[0028] The second motor 15 drives the first transmission rod 16 to rotate, which in turn drives the two first gears 17 to rotate.

[0029] The transmission assembly also includes a second transmission rod 18 fixedly connected inside the second first gear 17.

[0035] The position sensor 28 can sense when the linen has reached a designated position, thereby facilitating the repositioning of the linen.

[0036] When the linens are stacked to the moving height, the L-shaped limit plate 32 will affect the opening of the switch plate 23. At this time, the third motor 29 can be started to drive the third transmission rod 30 to rotate, which in turn drives the transmission roller 31 to rotate, which in turn drives the L-shaped limit plate 32 to rotate, thereby changing the position of the L-shaped limit plate 32 so that the L-shaped limit plate 32 will not affect the opening and closing of the switch plate 23.

[0037] The placement frame 2 is equipped with an auxiliary component, which includes a first fixing plate 24 fixedly connected inside the placement frame 2, an auxiliary platform 25 fixedly connected to the outside of the first fixing plate 24, and the end of the auxiliary platform 25 abutting against the end of the switch plate 23.

[0038] The position of the auxiliary platform 25 is fixed by the first fixing plate 24, so that the auxiliary platform 25 can assist in the movement of the linens.

A fourth conveyor belt 37 is rotatably connected to the outside of the two third conveyor rollers 35. A placement platform 38 is fixedly connected between the two third fixed plates 34.

[0040] The third conveyor roller 35 drives the third conveyor belt 36 and the fourth conveyor belt 37 to rotate, thereby moving the stacked linens to the placement platform 38.

[0041] The working principle and usage process of this utility model are as follows: The first motor 8 drives the screw 9 to rotate, which in turn drives the first transmission block 10 to move, which in turn drives the mounting frame 13 to move, which in turn drives the switch assembly to move, which in turn drives the linen to move, thereby changing the distance between the linen and the third conveyor belt 36, thereby reducing the time of free fall of the linen, thereby reducing the probability of the linen being unfolded, thereby reducing the possibility of uneven stacking, thereby reducing the possibility of rework of the linen in the future, thereby improving work efficiency.

[0042] Once the linens are at the appropriate height, the second motor 15 can be activated, which in turn drives the first transmission rod 16 to rotate, which in turn drives the two first gears 17 to rotate, which in turn drives the second transmission rod 18 to rotate, which in turn drives the first second gear 20 to rotate, which in turn drives the gear chain 21 to rotate, which in turn drives the second second gear 20 to rotate, which in turn drives the second first transmission rod 16 to rotate, which in turn drives the second transmission block 22 to rotate, which in turn drives the switch plate 23 to rotate, so that the linens that have moved onto the switch plate 23 can fall freely, thereby stacking the linens.
