Description

Technical Field

[0001] This utility model relates to the field of labeling device technology, specifically a labeling device for paper box production. Background Technology

[0002] Utility model patent CN206857171U discloses a cardboard box labeling machine, including a workbench with a horizontally positioned control cabinet. A cardboard box labeling device is vertically positioned at the center of the upper surface of the control cabinet. The cardboard box labeling device includes a labeling traction mechanism and a labeling mechanism. A conveyor platform is located in front of the control cabinet to transport the cardboard boxes to be labeled to the labeling mechanism for labeling. This conveyor platform is positioned close to the control cabinet. The labeling mechanism includes a vertical drive component and a horizontal drive component. The horizontal drive component drives the vertical drive component to move laterally. In this utility model, when the labeling traction mechanism conveys the labeling tape to the output end, the labeling mechanism, under the vertical push of a second cylinder, uses a pneumatic suction cup to pick up the label. Then, through the horizontal push of a first cylinder, the second cylinder is pushed above the cardboard box to be labeled, thus performing the labeling. This achieves an automatic labeling process, improves the accuracy of the labeling position, and increases work efficiency.

[0003] However, when using this device, the labeling efficiency of the cardboard boxes is low, and the device is not convenient for supporting and limiting cardboard boxes of different sizes. Utility Model Content

[0004] The purpose of this invention is to provide a labeling device for paper box production, which solves the problems of low labeling efficiency and inconvenience in supporting and limiting paper boxes of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a labeling device for paper box production, comprising a bracket, a support shaft mounted inside the bracket via bearings, a conversion mechanism mounted on the support shaft, a turntable fixedly connected to the upper end of the support shaft, an adjustment mechanism mounted on the turntable, a cylinder fixedly mounted to the upper end of the bracket, the cylinder rod of the cylinder passing through the bracket and slidably connected to the bracket, and a labeler fixedly connected to the lower end of the cylinder rod.

[0006] Preferably, the conversion mechanism includes a support, with the support fixedly connected to the inner bottom of the bracket, the support contacting the turntable, a gear fixedly connected to the outer side of the support shaft, and a motor fixedly installed on the inner bottom of the bracket. The motor's shaft passes through the bracket and is rotatably connected to it, with an incomplete gear fixedly connected to the lower end of the motor's shaft. A support ring is fixedly connected to the outer side of the support shaft, and an elastic plate is fixedly connected to the surface of the support ring. The motor drives the incomplete gear to rotate, causing it to rotate intermittently, which in turn causes the support shaft to drive the turntable to rotate. This facilitates the adjustment mechanism on the turntable to change work positions, allowing the device to change cardboard boxes without stopping the machine, resulting in more efficient labeling.

[0007] Preferably, a rod is fixedly connected to the lower end of the elastic plate, and the rod is slidably connected to the bracket. The rod facilitates positioning of the turntable after it rotates.

[0008] Preferably, the adjusting mechanism includes a screw barrel, a sprocket mounted inside the turntable via bearings, a screw threadedly connected inside the screw barrel, a support block fixedly connected to the upper end of the screw, a slide cylinder fixedly connected inside the support block, a slide rod slidably connected inside the slide cylinder, a spring disposed inside the slide cylinder, a top plate fixedly connected to the end of the slide rod, the top plate and the support block slidably connected, and a chain meshing with the outer side of the sprocket. By rotating the sprocket, the screw barrel rotates and the screw performs threaded motion, thereby adjusting the height of the support block, and the top plate can slide within the support block under the action of the spring, thus enabling the device to support and label cartons of different sizes and depths.

[0009] Preferably, a guide cylinder is fixedly connected to the upper end of the turntable, and a guide rod is slidably connected inside the guide cylinder. The guide rod and the support block are fixedly connected. By setting the guide cylinder and the guide rod in cooperation, the movement of the support block is guided.

[0010] Preferably, one end of the spring is fixedly connected to the slide rod, and the other end of the spring is fixedly connected to the support block. By providing the spring, the slide rod can be easily reset.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a motor to drive an incomplete gear to rotate, which in turn causes the gear to rotate intermittently, which in turn causes the support shaft to drive the turntable to rotate, which in turn makes it easy for the adjustment mechanism on the turntable to switch work positions, and thus the device can change the cardboard box without stopping the machine, making the labeling device more efficient.

[0013] 2. This utility model uses a rotating sprocket to drive the screw barrel to rotate and the screw to make a threaded motion, thereby making the height of the support block adjustable. The top plate can slide inside the support block under the action of a spring, thus enabling the device to support and label cardboard boxes of different sizes and depths.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-2 A labeling device for paper box production includes a bracket 1, a support shaft 2 mounted inside the bracket 1 via bearings, a conversion mechanism 3 mounted on the support shaft 2, a turntable 4 fixedly connected to the upper end of the support shaft 2, an adjustment mechanism 5 mounted on the turntable 4, a cylinder 6 fixedly mounted to the upper end of the bracket 1, the cylinder rod of the cylinder 6 passing through the bracket 1 and slidably connected to the bracket 1, and a labeler 7 fixedly connected to the lower end of the cylinder rod of the cylinder 6.

[0021] Please see Figures 1-3The conversion mechanism 3 includes a support 31. The support 31 is fixedly connected to the bottom inner side of the bracket 1. The support 31 is in contact with the turntable 4. A gear 32 is fixedly connected to the outer side of the support shaft 2. A motor 33 is fixedly installed on the bottom inner side of the bracket 1. The rotating shaft of the motor 33 passes through the bracket 1 and is rotatably connected to the bracket 1. An incomplete gear 34 is fixedly connected to the lower end of the rotating shaft of the motor 33. A support ring 35 is fixedly connected to the outer side of the support shaft 2. An elastic plate 36 is fixedly connected to the surface of the support ring 35. An insertion rod 37 is fixedly connected to the lower end of the elastic plate 36. The insertion rod 37 is slidably connected to the bracket 1. By setting the insertion rod 37, the turntable 4 can be easily positioned after rotation. The incomplete gear 34 is driven to rotate by the motor 33, which in turn causes the gear 32 to rotate intermittently. This causes the support shaft 2 to drive the turntable 4 to rotate, which makes it easy for the adjustment mechanism 5 on the turntable 4 to switch positions. This allows the device to change cardboard boxes without stopping the machine, making the labeling process more efficient.

[0022] Please see Figures 1-4 The adjusting mechanism 5 includes a screw cylinder 51. A sprocket 52 is mounted inside the turntable 4 via bearings. A screw 53 is threadedly connected inside the screw cylinder 51. A support block 54 is fixedly connected to the upper end of the screw 53. A guide cylinder 55 is fixedly connected to the upper end of the turntable 4. A guide rod 56 is slidably connected inside the guide cylinder 55. The guide rod 56 and the support block 54 are fixedly connected. The guide cylinder 55 and the guide rod 56 guide the movement of the support block 54. A slide cylinder 57 is fixedly connected inside the support block 54. A slide rod 58 is slidably connected inside the slide cylinder 57. A spring 59 is installed inside the slide cylinder 57. One end of spring 59 is fixedly connected to slide bar 58, and the other end of spring 59 is fixedly connected to support block 54. By setting spring 59, slide bar 58 can be easily reset. Top plate 510 is fixedly connected to the end of slide bar 58. Top plate 510 and support block 54 are slidably connected. Chain 511 is engaged on the outside of sprocket 52. By rotating sprocket 52, screw barrel 51 is driven to rotate and screw 53 is driven to make threaded movement, thereby making the height of support block 54 adjustable. Under the action of spring 59, top plate 510 can slide in support block 54, thereby enabling the device to support and label cardboard boxes of different sizes and depths.

[0023] The specific implementation process of this utility model is as follows: In use, according to the carton depth adjustment device, manually rotate the sprocket 52. The sprocket 52 drives the screw barrel 51 to rotate. The rotation of the screw barrel 51 and the screw 53 perform threaded motion, thereby causing the screw 53 to rise and fall. The screw 53 drives the support block 54 to rise and fall, thereby allowing the height of the support block 54 to be adjusted. Then, the carton is inverted and placed on the outside of the support block 54, with the edge of the carton contacting the top plate 510, causing the top plate 510 to move towards the support block 54. The top plate 510 drives the slide rod 58 to slide into the slide cylinder 57, thereby compressing the spring 59. Under the action of spring 59, the top plate 510 can slide within the support block 54, thereby enabling the device to support and label cartons of different sizes and depths. Then, the cylinder 6 is activated to drive the cylinder rod to extend and retract, which in turn drives the labeler 7 to rise and fall, labeling the cartons. The motor 33 is then activated, which drives the incomplete gear 34 to rotate. The rotation of the incomplete gear 34 drives the gear 32 to rotate intermittently, thereby causing the support shaft 2 to drive the turntable 4 to rotate. This allows the adjustment mechanism 5 on the turntable 4 to easily switch work positions, enabling the device to change cartons without stopping the machine, making the labeling process more efficient.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
