[0024] The application will be further described below in combination with the drawings and embodiments. These drawings are all simplified schematic views, and only illustrate the basic structure of the application in a schematic manner, so that only the components related to the application are shown.

[0025] In the description of the utility model, need understanding is, the term "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" orientation or positional relationship indicated for based on the orientation or positional relationship shown in the drawing, just for the convenience of describing the utility model and simplifying the description, and not indicate or imply the device or element indicated must have a particular orientation, with a particular orientation configuration and operation, therefore can not be understood as the restriction of the utility model. In addition, the features defined as "first", "second" can be explicitly or implicitly include one or more features. In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two.

[0026] In the description of the utility model, it should be explained that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] A bag pressing roller comprises a roller body 1 and bag pressing roller pieces 2, a plurality of bag pressing roller pieces 2 are arranged equidistantly along the axial direction of the roller body 1, and the bag pressing roller pieces 2 are detachably connected with the roller body 1.

[0028] The bag pressing roller piece 2 is circular, a bag pressing part 3 is arranged on the bag pressing roller piece 2, a plurality of bag pressing parts 3 are arranged along the circumferential direction of the bag pressing roller piece 2, the bag pressing roller piece 2 and the bag pressing part 3 form a regular polygon, a plurality of bag pressing grooves 4 are arranged on each side of the bag pressing roller piece 2 along the length direction of the side, the bag pressing groove 4 penetrates through the bag pressing roller piece 2 along the thickness direction of the bag pressing roller piece 2, and the width d of the groove opening of the bag pressing groove 4 is 1 / 10-1 / 9 times the length D of the side wall of the bag pressing roller piece 2.

[0029] Since the pressing bag roller piece 2 and the pressing bag part 3 form a regular polygon, the straight line distance between the right angle edge of the pressing bag roller piece 2 and the other roller is larger than the straight line distance between the pressing bag part 3 and the other roller, so that the space for containing is formed between the right angle edge of the pressing bag roller piece 2 and the other roller, and the garbage bag moves towards the other roller through the space for containing along with the rotation of the roller body 1, and the pressing bag part 3 pushes and extrudes the garbage bag towards the other roller body 1. If the number of the pressing bag parts 3 on the pressing bag roller piece 2 is small, such as the pressing bag roller piece 2 is a regular triangle or a regular quadrilateral, the volume of the space for containing is large, but the distance between the adjacent pressing bag parts 3 is long, the pressing bag efficiency is low, and the garbage bag is easy to accumulate in the space for containing; if the number of the pressing bag parts 3 on the pressing bag roller piece 2 is large, such as the pressing bag roller piece 2 is a regular decagon, the volume of the space for containing is small, so that the garbage of the large bag is difficult to transmit forward. Therefore, preferably, the pressing bag roller piece 2 in the application is a regular hexagon, and the number of the pressing bag parts 3 on each pressing bag roller piece 2 is six.

[0030] The roller body 1 is hollow, and the outer side wall of the roller body 1 is provided with a containing groove 5 along the axial direction thereof, and a plurality of flat keys 6 are arranged on the roller body 1 along the axial direction thereof, the flat keys 6 are located in the containing groove 5, the flat keys 6 protrude from the groove opening of the containing groove 5, the number of the flat keys 6 on the roller body 1 is the same as the number of the bag hooking roller pieces, and the flat keys 6 are connected with the inner side wall of the bag hooking roller pieces.

[0031] A plurality of shaft sleeves 7 are sleeved on the roller body 1, the number of the shaft sleeves 7 is one more than that of the pressing bag roller pieces 2, the shaft sleeves 7 are arranged at intervals with the flat keys 6, the shaft sleeves 7 are provided with key grooves 8 for inserting the flat keys 6, so that the plurality of shaft sleeves 7 fix the flat keys 6 on the driving main shaft, and two shaft covers 11 are connected with the two ends of the roller body 1 through bolts, respectively, and the plurality of shaft sleeves 7 are clamped on the roller body 1 by the shaft covers 11.

[0032] The outer side wall of the shaft sleeve 7 is further provided with a plurality of protrusions 9 arranged along the axial direction of the shaft sleeve 7, and the side wall opposite to the rotation direction of the roller piece is provided with a pressing surface 10, and the pressing surface 10 is arranged obliquely towards the direction opposite to the rotation direction of the roller body 1.

[0033] In summary, a plurality of pressing bag grooves 4 are arranged on the edge of the pressing bag part 3, so that when the garbage bag is extruded, the pressing bag part 3 can firmly hold the garbage bag and transmit and extrude the garbage bag towards the other roller body, thereby improving the garbage treatment efficiency. The roller piece is detachably installed on the roller body 1 through the embedding of the shaft sleeve 7 and the flat key 6 on the roller body 1, the stress strength of the pressing bag part 3 is improved through the design of the shape of the roller piece and the reasonable layout of the pressing bag part 3, and the service life of the roller piece is improved.

[0034] On the other hand, the pressing bag roller piece 2 is arranged as a hexagon, so that a reasonable containing space is formed between the pressing bag roller piece 2 and the other roller, so that the garbage can be transported towards the outlet direction, the pressing bag part 3 pushes and extrudes the garbage towards the outlet at a suitable time interval, thereby improving the garbage bag breaking and conveying efficiency.

[0035] The way of clamping and fixing the roller pieces by the shaft sleeve 7 in the application is convenient for replacing the roller pieces, and only the shaft cover 11 at the end needs to be removed to replace all the roller pieces.

[0036] With the above ideal embodiments of the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined by the scope of the claims.
