Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1-Figure 2 The supporting assembly 3 includes a supporting plate 31, which is fixedly connected to the right side surface of the processing table 1. The bottom end of the outer wall of the guide plate 36 contacts the surface of the conveyor belt 2. The contact between the two supports the object to be supported and maintained at the center through the guide plate 36. The inner wall of the top of the supporting plate 31 passes through and is slidably connected with a moving rod 34. The inner wall of the top of the supporting plate 31 is elastically connected with a plug rod 32 through a limit spring 33. The surface of the moving rod 34 is provided with a plurality of groups of through holes. The bottom end of the outer wall of the plug rod 32 is plugged into the inner wall of the through hole. The plugging between the two allows the moving rod 34 to drive two groups of hinged rods 35 and the guide plate 36 to guide and fix the object to multiple positions after moving according to the size of the object. The plug rod 32 passes through and is slidably connected to the inner wall of the top of the supporting plate 31. One end of the limit spring 33 is fixedly connected to the surface of the plug rod 32, and the other end of the limit spring 33 is fixedly connected to the inner wall of the top of the supporting plate 31. The function of the limit spring 33 is to automatically reset the position of the plug rod 32 after it is pulled outward.

[0038] Reference Figure 2The top of the outer wall of the guide plate 36 is fixedly connected to a sliding rod 37, and a guide groove is provided at the top of the inner side wall of the support plate 31. The top of the outer wall of the sliding rod 37 is slidably connected to the inner wall of the guide groove at the top of the inner side wall of the support plate 31. By providing a guide groove on the inner side wall of the support plate 31, the guide plate 36 can only be adjusted laterally. The inner side wall of the guide plate 36 is rotatably connected to multiple sets of auxiliary wheels 38. By setting multiple sets of auxiliary wheels 38, when the guide plate 36 guides and supports an object, the auxiliary wheels 38 can be used to reduce the friction of its moving position to keep it in the centered position.

[0039] Reference Figure 1 and Figure 3-Figure 4 The mounting assembly 4 includes a turntable 41, which is provided with two groups. The two groups of turntables 41 are rotatably connected to the surfaces on both sides of the top of the processing table 1. The outer wall of the fixed column 42 is sleeved with a label tube, so that when the guide wheel 5 rotates to transport the label, the turntable 41 will also rotate, so that the label tube installed on the surface of the fixed column 42 can rotate and transport the label. The top of the outer wall of the turntable 41 is fixedly connected with a fixed column 42, and the outer wall of the fixed column 42 is provided with a plurality of groups of vertical grooves. The outer wall of the slider 46 is provided with a protrusion, and the part of the protrusion of the slider 46 is slidably connected to the inner wall of the vertical groove of the fixed column 42. By providing a guide groove that fits the slider 46 on the inner wall of the fixed column 42, the slider 46 can only move up and down when the slider 46 rotates with the two-way threaded rod 43, and will not rotate synchronously with the rotation of the two-way threaded rod 43.

[0040] Reference Figure 3-Figure 4 The inner wall of the fixed column 42 is rotatably connected with a bidirectional threaded rod 43, and a handle is provided on the surface of the bidirectional threaded rod 43, by which the bidirectional threaded rod 43 can be quickly rotated, and the bidirectional threaded rod 43 is a prior art, and its surface is provided with two sets of upper and lower threads, and the directions of the two sets of threads are opposite, so that when it is rotated, it can drive the two sets of sliders 46 to move closer to each other or away from each other, and the surface of the bidirectional threaded rod 43 is threadedly connected with the upper and lower sets of sliders 46, and the inner wall of the fixed column 42 is provided with a cavity, and the slider 46 is slidably connected to the inner wall of the cavity of the fixed column 42, and the outer walls of the two sets of sliders 46 are hinged with a connecting rod 44, and the end of the connecting rod 44 away from the slider 46 is hinged with an arc plate 45, and when the bidirectional threaded rod 43 is rotated, the two sets of sliders 46 will move toward each other on its surface, or move away from each other, so that the connecting rod 44 can pull multiple sets of arc plates 45 to expand or contract outward, so as to install and fix according to label tubes with different inner diameters.

[0041] Working principle: Start the motor inside the conveyor belt 2 to make it run and drive the conveyor belt 2 to work, place the object to be labeled on the surface of the conveyor belt 2 for transportation, when the object moves on the conveyor belt 2, adjust the support component 3 according to the size of the object, pull the insertion rod 32 outward to separate it from the through hole on the surface of the moving rod 34, release the fixation of the moving rod 34, move the moving rod 34, and drive the guide plates 36 to move toward or away from each other through the hinge rod 35 to adapt to the width of the object, release the insertion rod 32, and under the action of the limit spring 33, the insertion rod 32 is reinserted into the through hole of the moving rod 34 to fix the position of the guide plate 36, and the auxiliary wheel 38 on the inner side wall of the guide plate 36 contacts the object, while reducing the friction, so that the object is kept in the center position of the conveyor belt 2 to ensure the accuracy of the labeling position.

[0042] When preparing for labeling, the label tube is installed through the installation component 4, and the handle of the bidirectional threaded rod 43 is turned. The bidirectional threaded rod 43 rotates. Since the threads on its surface are in opposite directions, the upper and lower sets of sliders 46 are driven to move toward or away from each other on the inner wall of the cavity of the fixed column 42. When the sliders 46 move, the arc plate 45 is pulled outward by the connecting rod 44 to expand or contract, thereby adapting to label tubes of different inner diameters and fixing the label tube on the fixed column 42.

[0043] When the conveyor belt 2 conveys an object passing through the guide wheel 5, the guide wheel 5 rotates to drive the label to be conveyed, and the label is attached to both sides of the object through the labeling plate 6, completing the fully automatic double-sided labeling process. During the label conveying process, the turntable 41 rotates as the label is pulled to ensure smooth label conveying.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
