[0024] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0025] As shown in the figure, Figures 2-5 The present application provides a positioning device for a counter-lining wheel of a packaging machine, which is applied to the axial positioning of a counter-lining wheel 1-2 of a packaging machine in a cigarette factory. The positioning device is used as an auxiliary tool to axially position and adjust the counter-lining wheel 1-2 of the packaging machine. In the past, the position of a gumming wheel 1-1 was fixed and could not be adjusted when the counter-lining wheel 1-2 of the packaging machine was adjusted. The counter-lining wheel 1-2 was installed on a rotating shaft by locking screws. After the locking screws of the counter-lining wheel 1-2 were loosened, the axial position of the counter-lining wheel 1-2 was manually adjusted by a worker. Then, the worker visually ensured that the outer circumferential groove of the counter-lining wheel 1-2 was aligned with the gumming wheel 1-1. However, the precise alignment of the groove of the counter-lining wheel 1-2 with the gumming wheel 1-1 could not be ensured. The alignment of the groove of the counter-lining wheel 1-2 with the gumming wheel 1-1 could be ensured only after multiple trial runs and adjustments. Thus, the adjustment of three counter-lining wheels 1-2 had to be sequentially completed. The whole process was relatively troublesome, time-consuming and labor-intensive, and was not conducive to the improvement of the overall production efficiency of the equipment. The positioning device for the counter-lining wheel 1-2 of the packaging machine provided by the present application is designed to conveniently and quickly complete the adjustment of the counter-lining wheel 1-2 of the packaging machine.

[0026] The packaging machine counter wheel 1-2 positioning device comprises a device body 100, a first side 101, a second side 102 and a third side 103 are arranged on the device body 100, the first side 101 can constitute a reference plane, the second side 102 can constitute a reference plane, and the third side 103 can constitute a reference plane, at this point, constituting a reference plane means that it can form at least three-point contact with other planes, and the three positions of the three-point contact are not all on the same straight line, that is, it can form stable contact with other planes, preferably, the first side 101, the second side 102 and the third side 103 are all planes, the first side 101, the second side 102 and the third side 103 can form a plane contact with other planes, the second side 102 is parallel to the first side 101, the third side 103 is parallel to the first side 101, preferably, the first side 101, the second side 102 and the third side 103 are parallel to each other, and the third side 103 is located between the first side 101 and the second side 102, the third side 103 is formed by the partial direction of the first side 101 offsetting towards the second side 102, that is, the partial direction of the first side 101 is recessed and offset towards the second side 102, forming a structure similar to a ladder, the recessed area is the third side 103, so that the third side 103 and the first side 101 form a ladder structure, so, as shown in Figure 5 the first side 101 and one side of the rubberizing wheel 1-1 are abutted on the outside first, then the corresponding counter wheel 1-2 of the rubberizing wheel 1-1 is adjusted, so that the outer side of the counter wheel 1-2 and the third side 103 are abutted, then the axial adjustment and positioning of the counter wheel 1-2 are realized, the counter wheel 1-2 is locked, then the device body 100 is placed between the counter wheel 1-2 and the intermediate counter wheel 1-2, the intermediate counter wheel 1-2 is loosened and axially adjusted, so that the opposite sides of the two adjacent counter wheels 1-2 abut against the first side 101 and the second side 102 respectively, then the intermediate counter wheel 1-2 is locked, so that the axial positioning of the intermediate counter wheel 1-2 is completed, and the positioning of the last counter wheel 1-2 is completed by the same method, in this method, because the positions of the rubberizing wheels 1-1 are fixed and unchanged in the initial state, when the positions of the counter wheels 1-2 and the rubberizing wheels 1-1 are accurately corresponding, the spacing between the adjacent counter wheels 1-2 is also a fixed value, with the long-time operation of the equipment, the counter wheels 1-2 have axial deviation, and the counter wheels 1-2 are restored to the vertical position state by the device body 100.

[0027] In practice, for the three glue applying wheels 1-1 and the three counter wheels 1-2, the axial thickness of the glue applying wheel 1-1 is 9 mm, the space distance between the two adjacent glue applying wheels 1-1 is 33 mm, the distance between the center lines of the two adjacent glue applying wheels 1-1 is 42 mm, the axial width of the counter wheel 1-2 is 18 mm, and the axial width of the groove at the outer periphery of the counter wheel 1-2 is 10.5 mm. Therefore, the distance between the first side surface 101 and the second side surface 102 is 24 mm, and the distance between the first side surface 101 and the third side surface 103 is 4.5 mm, so that the axial positioning of each counter wheel 1-2 can be accurately completed, the counter wheel 1-2 and the corresponding glue applying wheel 1-1 are accurately aligned, the required adjustment time is greatly reduced, the adjustment of the counter wheel 1-2 is more convenient and fast, and the overall production efficiency of the equipment is improved.

[0028] More preferably, the fourth side surface 104 is arranged between the first side surface 101 and the third side surface 103, and the two sides of the fourth side surface 104 are transitionally connected with the first side surface 101 and the third side surface 103, respectively. In an embodiment, the first side surface 101 and the third side surface 103 are perpendicularly connected with the fourth side surface 104, respectively. The fourth side surface 104 extends along a direction parallel to the first side surface 101 and parallel to the third side surface 103. The fourth side surface 104 has a certain length, one side of the fourth side surface 104 is perpendicularly connected with the first side surface 101, and the other side of the fourth side surface 104 is perpendicularly connected with the third side surface 103. In this way, the first side surface 101 and the third side surface 103 form a vertical stepped structure. During adjustment, the fourth side surface 104 can abut against the bottom of the counter wheel 1-2, so that the bottom of the counter wheel 1-2 is tangent to the fourth side surface 104, and the positioning is more convenient.

[0029] In an embodiment, a first scale line 201 is arranged on the first side 101 near the fourth side 104 along the direction of the fourth side 104, that is, the scale line is arranged on the edge of the first side 101 near the fourth side 104, and the scale line is arranged along the direction of the fourth side 104, so that the positioning operation is facilitated. More preferably, the first scale line 201 can include a straight line which is on the edge of the first side 101 and parallel to the direction of the fourth side 104, so that the straight line can play a role of a reference position. Because in practice, the vertical distance between the bottom of the contrast wheel 1-2 and the top of the glue applying wheel 1-1 also has a specified requirement, the distance between the straight line of the first scale line 201 and the connecting line between the first side 101 and the fourth side 104 is set as the specified vertical distance, when adjusting the first contrast wheel 1-2, the straight line of the first scale line 201 is tangent to the top of the glue applying wheel 1-1, and the bottom of the contrast wheel 1-2 is tangent to the fourth side 104 and abuts against the fourth side 104, which indicates that the distance between the bottom of the contrast wheel 1-2 and the top of the glue applying wheel 1-1 meets the requirement, otherwise, the shaft body of the contrast wheel 1-2 needs to be adjusted.

[0030] More preferably, a second scale line 202 is arranged on the first side 101 along the direction perpendicular to the direction of the fourth side 104, the direction of the second scale line 202 is perpendicular to the direction of the first scale line 201, and the second scale line 202 intersects the middle part of the first scale line 201, so that the vertical distance between the top of the glue applying wheel 1-1 and the bottom of the contrast wheel 1-2 is more intuitively understood through the second scale line 202.

[0031] In some embodiments, in the projection in the direction perpendicular to the first side 101, the projection of the first side 101 and the projection of the third side 103 are both located in the projection of the second side 102.

In this embodiment, the device body 100 can be a cylindrical structure, the end of the device body 100 is partially recessed, so that the end face of the partially recessed end of the device body 100 is formed as the first side surface 101, the partially recessed part forms the third side surface 103, and the other end face of the device body 100 is formed as the second side surface 102. The device body 100 is a cylindrical structure, and the two axial end faces of the device body 100 are the first side surface 101 and the second side surface 102, respectively. The first side surface 101 is provided with a recessed stepped structure, and the recessed stepped structure is recessed and offset towards the direction of the second side surface 102, that is, the third side surface 103 and the fourth side surface 104 are formed. The fourth side surface 104 is connected between the first side surface 101 and the third side surface 103. The first side surface 101 and the second side surface 102 are parallel, the first side surface 101 and the third side surface 103 are parallel, the fourth side surface 104 and the third side surface 103 are perpendicular, the fourth side surface 104 and the first side surface 101 are perpendicular, the distance between the first side surface 101 and the second side surface 102 is 24 mm, the width of the fourth side surface 104 is 4.5 mm, that is, the distance between the first side surface 101 and the third side surface 103 is 4.5 mm, and the area of the third side surface 103 is smaller than the area of the first side surface 101. The first scale line 201 is arranged along the edge of the first side surface 101 close to the fourth side surface 104, and the second scale line 202 passes through the axis of the device body 100 and is perpendicular to the first scale line 201. In this way, the cylindrical device body 100 is convenient for the operator to hold and operate, occupies less space, is convenient for positioning operation in the equipment gap, and can be made by removing part of the overall cylindrical material, which is convenient for manufacturing and reduces production cost.
