Description

TECHNICAL FIELD

[0001] The utility model relates to a box body labeling equipment. BACKGROUND

[0002] After injection molding product production is completed, generally will be installed in the box body, and the label is pasted on the outside of the box body, and then is shipped.

[0003] Generally, the box body labeling equipment is used to paste the label on the outside of the box body, and some box bodies need to paste the label on the front and back sides respectively, and the existing box body labeling equipment capable of pasting the label on the front and back sides of the box body respectively comprises: a conveying belt extending along the left-right direction, provided with racks on the front and back sides respectively and used for conveying the box body from left to right, and a pair of labeling mechanisms separately provided on the racks on the front and back sides and used for pasting the label on the front and back sides of the box body respectively.

[0004] During labeling production, the box bodies are placed on the left end of the conveying belt one by one, the conveying belt conveys the box bodies from left to right, and when the box bodies are conveyed to the pair of labeling mechanisms, the pair of labeling mechanisms pastes the label on the front and back sides of the box body respectively (the labeling mechanism on the front side rack pastes the label on the front side of the box body, and the labeling mechanism on the back side rack pastes the label on the back side of the box body).

[0005] However, in the actual production process, the box body needs to be on the center line of the conveying belt (that is, the distance between the front side of the box body and the front side rack is equal to the distance between the back side of the box body and the back side rack), and only then the pair of labeling mechanisms can accurately paste the label on the front and back sides of the box body respectively; when the box bodies are placed on the left end of the conveying belt one by one, it cannot be guaranteed that every box body is on the center line of the conveying belt; if the box body is not on the center line of the conveying belt, only one labeling mechanism of the pair of labeling mechanisms can effectively contact the box body, and then only one side of the front and back sides of the box body is pasted with the label, finally resulting in that the box body lacks the label.

[0019] The specific embodiments of the utility model are described further below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0020] The technical scheme of the specific embodiment of the utility model is as follows:

[0022] The positioning mechanism 3 comprises: located directly above the conveying belt 1, extending along the left and right direction and the bottom end abutting the conveying belt 1 guide slide plate 41, located outside the guide slide plate 41, horizontally along the front and back direction, one end is rotatably connected with the outer side of guide slide plate 41 through bearing 42, the other end is provided with steering wheel 45 screw rod 43, screw rod seat 44 is arranged on the corresponding rack 11, is penetrated by screw rod 43 and is screwed with screw rod 43, sliding groove 55 is arranged on the corresponding rack 11, extending along the left and right direction and located at the left side of screw rod seat 44, sliding block 53 is arranged in sliding groove 55 and is slidably connected with sliding groove 55, spring 54 is arranged in sliding groove 55, located at the right side of sliding block 53, extending along the left and right direction and being compressed by sliding block 53, the bottom end and the top end of sliding block 53 are fixedly connected with vertical rod 52, and one end of vertical rod 52 is fixedly connected with vertical rod 52, and the other end is fixedly connected with the left end of the inner side of guide slide plate 41 (the inner side of guide slide plate 41 is the side of guide slide plate 41 facing the center line of conveying belt 1, and the outer side of guide slide plate 41 is the side of guide slide plate 41 away from the center line of conveying belt 1); the distance between guide straight strip 51 and conveying belt 1 is less than the thickness of box body 6 (preferably, the distance between guide straight strip 51 and conveying belt 1 is equal to half of the thickness of box body 6);

[0023] The guide slide plates 41 of the pair of positioning mechanisms 3 are respectively arranged on the front and back sides of the center line of the conveying belt 1, and the guide slide plates 41 of the pair of positioning mechanisms 3 are symmetrically arranged with the center line of the conveying belt 1 as the symmetry axis; the bearings 42 of the pair of positioning mechanisms 3 are symmetrically arranged; the screw rods 43 of the pair of positioning mechanisms 3 are symmetrically arranged; the screw rod seats 44 of the pair of positioning mechanisms 3 are symmetrically arranged; the sliding grooves 55 of the pair of positioning mechanisms 3 are symmetrically arranged; the sliding blocks 53 of the pair of positioning mechanisms 3 are symmetrically arranged; the springs 54 of the pair of positioning mechanisms 3 are symmetrically arranged; the vertical rods 52 of the pair of positioning mechanisms 3 are symmetrically arranged; the guide straight strips 51 of the pair of positioning mechanisms 3 are symmetrically arranged.

[0024] The working principle of this box labeling device includes:

[0025] Before labeling production, the spacing of the guide plates 41 of the pair of positioning mechanisms 3 is adjusted. Specifically, the corresponding screw 43 is rotated by the throttle 45 (making the throttle 45 move closer to or away from the corresponding screw seat 44), and then the corresponding guide plate 41 is driven closer to or away from the center line of the conveyor belt 1 by the screw 43; until the spacing between the guide plates 41 of the pair of positioning mechanisms 3 and the center line of the conveyor belt 1 is equal (that is, the guide plates 41 of the pair of positioning mechanisms 3 are symmetrically arranged with respect to the center line of the conveyor belt 1), and the spacing between the guide plates 41 of the pair of positioning mechanisms 3 is just enough for the box 6 to pass through; and since the spring 54 in the slide 55 is always compressed by the corresponding slider 53, the guide bars 51 of the pair of positioning mechanisms 3 are always taut during the process of adjusting the spacing between the guide plates 41 of the pair of positioning mechanisms 3; the spacing between the guide bars 51 of the pair of positioning mechanisms 3 is always gradually narrowed from left to right, that is, the guide bars 51 of the pair of positioning mechanisms 3 are always gradually narrowed from the outside of the conveyor belt 1 to the facing surfaces of the guide plates 41 of the pair of positioning mechanisms 3.

[0026] Then the labeling production begins. The cube boxes 6 are placed one by one at the left end of the conveyor belt 1. The conveyor belt 1 transports the boxes 6 from left to right. The boxes 6 first pass through a pair of positioning mechanisms 3, and then through a pair of labeling mechanisms 2.

[0027] When box 6 passes a pair of positioning mechanisms 3, the pair of positioning mechanisms 3 can position box 6 on conveyor belt 1 (so that box 6 is on the center line of conveyor belt 1); specifically: if box 6 is on the center line of conveyor belt 1 (that is, the distance between the front side of box 6 and the front frame 11 is equal to the distance between the rear side of box 6 and the rear frame 11), then box 6 can pass between the guide plates 41 of the pair of positioning mechanisms 3; if box 6 deviates from the center line of conveyor belt 1, then before box 6 passes the guide plates 41 of the pair of positioning mechanisms 3, it will first contact the guide bar 51 of one of the positioning mechanisms 3, and then during the process of box 6 being conveyed from left to right, the guide bar 51 in contact with box 6 can gradually guide box 6, so that box 6 gradually approaches the center line of conveyor belt 1, until box 6 reaches the guide plates 41 of the pair of positioning mechanisms 3, then box 6 can be guided to be on the center line of conveyor belt 1, and thus can pass between the guide plates 41 of the pair of positioning mechanisms 3;

[0028] When the box 6 is conveyed to a pair of labeling mechanisms 2, the pair of labeling mechanisms 2 apply labels to the front and back sides of the box 6 respectively (the labeling mechanism 2 on the front frame 11 applies labels to the front side of the box 6, and the labeling mechanism 2 on the rear frame 11 applies labels to the rear side of the box 6); since the labeling mechanism 2 is existing technology, the specific structure and working principle of the pair of labeling mechanisms 2 will not be described in detail in this utility model.

[0029] From above, the box body labeling equipment can label the box body 6 through a pair of labeling mechanisms 2 on the front and back sides respectively; and can guide and position the box body 6 to be on the center line of the conveying belt 1 before labeling, thereby ensuring that the pair of labeling mechanisms 2 can effectively contact the box body 6, and the box body 6 can be prevented from lacking labels due to not being on the center line of the conveying belt 1.

[0030] The above is only the preferred embodiment of the present application, and it should be pointed out that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of protection of the present application.
