[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that: similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0028] This embodiment mainly elaborates on the detachable structure of the feeding device of a non-woven bag making machine that can independently disassemble and assemble the rubber roller, specifically as follows:

[0029] As Figures 1-5 shown, the detachable structure of the feeding device of the non-woven bag making machine includes a housing 1 and a rubber roller that is detachably and rotatably installed on the housing 1. The rubber roller includes a roller body 4 and a shaft rod 6. An inner layer 16 is provided on the shaft rod 6, and the roller body 4 is wrapped outside the inner layer 16.

[0030] An installation groove 15 is formed on the housing 1. The installation groove 15 is rectangular. The notch of the installation groove 15 is provided on the inner wall of the housing 1 and communicates with the outer wall of the housing 1. A slidably installed positioning block 7 is provided in the installation groove 15, and a U-shaped groove 14 is provided on the outer wall of the installation groove 15. The width of the U-shaped groove 14 is smaller than that of the installation groove 15, which limits the positioning block from detaching along the notch direction, facilitating better installation guidance when slidably installing the positioning block 7 and improving the installation efficiency.

[0031] A number of shaft holes are provided on the positioning block 7. The shaft rod 6 is rotatably connected to the shaft holes. The roller body 4 is located between the two positioning blocks 7. The outer diameter of the roller body 4 is larger than the inner diameter of the shaft holes. The positioning block restricts the axial sliding of the rubber roller on the housing 1. Preferably, the roller body 4 can be arranged between the positioning block 7 and the housing 1.

[0032] In this application, through the detachable setting of the positioning block 7 on the housing 1, the rubber roller can be individually disassembled and replaced without overall disassembly, improving the replacement efficiency of the rubber roller and reducing the replacement cost.

[0033] The shaft holes on the positioning block 7 are divided into a first shaft hole 11 and a second shaft hole 12. Bearings 10 are installed in both the first shaft hole 11 and the second shaft hole 12. The two ends of the shaft rod 6 are rotatably connected to the bearings 10. The setting of the bearings 10 can prevent the ends of the shaft rod 6 from abutting against the side walls of the installation groove 15, reduce the loss of the shaft rod 6 during the operation of the equipment, and improve the operation efficiency of the equipment.

[0034] The installation of the bearing 10 in this patent is not limited to the situation where bearings 10 are installed in both the first shaft hole 11 and the second shaft hole 12. The rotational connection of the shaft rod 6 on the positioning block 7 can also be achieved by installing a bearing 10 in one of the first shaft hole 11 and the second shaft hole 12.

[0035] As Figures 1-2 shown, a fastener 8 is detachably installed between the positioning block 7 and the housing 1. A threaded hole 13 is provided on the fastener 8, and hole grooves corresponding to the threaded hole 13 on the fastener 8 are provided on the outer wall of the housing 1 and the positioning block 7 respectively. When the positioning block 7 is slidably installed in the installation groove 15, a bolt 9 is screwed into the threaded hole 13 on the fastener 8 to complete the fixation of the positioning block 7. The fastener 8 restricts the positioning block 7 from detaching from the installation groove 15.

[0036] Furthermore, the hole groove on the housing 1 corresponding to the threaded hole 13 on the fastener 8 is not limited to being provided on the outer wall of the housing 1. The fastener 8 can also be detachably installed on the inner wall of the housing 1 through a bolt 9.

[0037] In other embodiments, the fastener 8 can be fixedly connected to the positioning block 7 by welding.

[0038] One end of the shaft rod 6 extends out of the outer shell, and a transmission mechanism 5 for connecting to the motor is provided at one end of the shaft rod 6. The transmission structure 5 and the motor can adopt gear meshing or belt pulley transmission, etc., to provide power for the operation of the equipment.

[0039] In this embodiment, two groups of rubber rollers are installed on the housing. A first gear 2 is installed on the shaft rod 6. The first gear 2 is located between the roller body 4 and the positioning block 7 or the inner wall of the housing 1. A second gear 3 is installed on the other group of rubber rollers. The second gear 3 is located above the first gear 2. The first gear 2 meshes with the second gear 3 to ensure the accuracy and stability of power transmission, making the equipment operate more precisely and reliably.

[0040] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0041] The detachable structure of the feeding device of the non-woven fabric bag making machine provided by the present utility model has been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
