Description

Technical Field

[0001] The utility model relates to the field of labeling machines, in particular to a paper box paging automatic printing and labeling machine. Background Art

[0002] A carton labeling machine is an automated device that is mainly used to attach labels to cartons or other packaging materials. This machine is widely used in the food, beverage, medicine, cosmetics, daily necessities and other industries to improve production efficiency and ensure the consistency and accuracy of labels. In order to improve labeling efficiency, existing carton labeling machines stack cartons vertically in a feed frame, and convey the bottom cartons one by one along the conveyor belt to the labeling machine at the front end for labeling. However, when cartons are separated from the feed frame one by one at the feed frame, it is easy for multiple cartons to be stacked together and conveyed out, resulting in the inability to label the bottom cartons, affecting the yield rate. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a paper box paging automatic printing and labeling machine in view of the deficiencies of the above-mentioned prior art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paper box paging automatic printing and labeling machine, comprising a frame, a feeding frame arranged at one end of the frame for stacking paper boxes, a labeling machine, and a second conveyor belt for conveying the paper boxes at the bottom of the feeding frame to the labeling machine for labeling, a first conveyor belt is arranged at the bottom of the feeding frame, a paper box paging assembly is arranged between the first conveyor belt and the second conveyor belt, the paper box paging assembly comprises a paging conveyor belt arranged above the frame, two ends of the paging conveyor belt are respectively mounted above the first conveyor belt and the second conveyor belt, and there is a width-limited gap between the paging conveyor belt and the first conveyor belt for the paper boxes to pass through one by one.

[0005] By adopting the above technical solution, the limited width gap formed by the paging conveyor belt between the first conveyor belt and the second conveyor belt is utilized, so that the paper boxes in the discharge frame can only enter the second conveyor belt from the first conveyor belt through the limited width gap, and the limited width gap is set to the thickness of the first paper box so that only one paper box can pass through at the same time. In this way, the paper boxes can be separated and conveyed one by one, avoiding the stacking output of paper boxes and improving the yield rate.

[0006] The above-mentioned paper box paging automatic printing and labeling machine can be further configured as follows: the paper box paging assembly also includes a paging frame, a paging shaft fixedly connected to the paging frame, a first conveying wheel rotatably arranged on one end of the paging frame facing the material discharge frame, and a second conveying wheel sleeved on the paging shaft, the paging conveyor belt is wound around the first conveying wheel and the second conveying wheel, and the paging frame is connected to the frame through the paging shaft.

[0007] By adopting the above technical solution, through the cooperation of the paging shaft and the paging conveyor belt, and the setting of the first conveyor wheel and the second conveyor wheel, it is ensured that the paging conveyor belt can provide stable support and guidance during the paper box paging process, wherein the paging conveyor belt can be without a power source, and only needs to cooperate with the first and second conveyor belts to rotate, thereby realizing stable paper box transportation.

[0008] The above-mentioned paper box paging automatic printing and labeling machine can be further configured as follows: a gap adjustment component is provided at the position of the frame corresponding to the paging conveyor belt, and the gap adjustment component includes a height adjustment seat arranged at both ends of the frame, a height adjustment groove is opened in the height adjustment seat, and a height adjustment bolt is arranged inside, the two ends of the paging shaft are inserted into the height adjustment groove and are threadedly connected with the height adjustment bolt, and the paging shaft is driven close to or away from the frame by rotating the height adjustment bolt.

[0009] By adopting the above technical solution and the design of height adjustment bolts and height adjustment slots, the operator can manually adjust the height position of the paging shaft according to the size of the paper box, thereby changing the gap size between the paging conveyor belt and the first conveyor belt to accommodate paper boxes of different thicknesses passing through one by one.

[0010] The above-mentioned carton paging automatic printing and labeling machine can be further configured as follows: a plurality of stop rods are provided above the paging conveyor belt corresponding to the frame, a paper passing gap exists between the stop rods and the frame, and the stop rods cooperate with the paper boards on both sides to form the material discharge frame.

[0011] By adopting the above technical solution, the blocking rod cooperates with the paper board to form a stable paper feeding frame structure. The paper passing gap between the blocking rods allows the paper boxes to pass through one by one, and the blocking rods themselves prevent the paper boxes from moving horizontally, avoiding the paper boxes from passing over the paging conveyor belt, thereby improving the stability of the paging conveyor.

[0012] The above-mentioned paper box paging automatic printing and labeling machine can be further configured as follows: the number of the material blocking rods is 2, and they are respectively arranged on both sides of the paging conveyor belt, and the frame is provided with material blocking racks on both sides corresponding to the paperboard placement, and at least two material blocking adjustment shafts are provided between the material blocking racks, and the material blocking rods are all sleeved on the outer peripheral surface of the material blocking adjustment shaft and can slide left and right along the material blocking adjustment shaft.

[0013] By adopting the above technical solution, the blocking rod is sleeved on the blocking adjustment shaft and can slide left and right along the shaft. By adjusting the height adjustment bolt, the distance between the blocking rod and the paging conveyor belt can be changed to adapt to paper boxes of different widths.

[0014] The above-mentioned paper box paging automatic printing and labeling machine can be further configured as follows: the material blocking rod is slidably connected to the material blocking adjustment shaft through a material blocking adjustment seat, the material blocking adjustment seat is sleeved on the outer circumferential surface of the material blocking adjustment shaft, a height adjustment groove is opened on the material blocking rod, a height adjustment groove is penetrated by a height control bolt, the height control bolt passes through the height adjustment groove and is connected to the material blocking adjustment seat, and enables the material blocking rod to be close to or away from the first conveyor belt relative to the material blocking adjustment seat.

[0015] By adopting the above technical solution, the cooperation of the height adjustment slot on the material blocking rod and the height control bolt allows the operator to adjust the height of the material blocking rod according to the thickness of different cartons to ensure the stability of the cartons during the conveying process.

[0016] The above-mentioned paper box paging automatic printing and labeling machine can be further configured as follows: the end of the material blocking rod is provided with a guide block which gradually narrows axially along the direction from the first conveyor belt to the second conveyor belt.

[0017] By adopting the above technical solution, the design of the guide block gradually narrowing along the conveyor belt direction can guide the paper box to maintain the correct direction when passing through the paging conveyor belt, thereby reducing conveying failures caused by paper box deviation.

[0018] The above-mentioned paper box paging automatic printing and labeling machine can be further configured as follows: the labeling machine includes a printer and a labeling rack arranged above the second conveyor belt, the labeling rack is provided with a label peeling plate at one end corresponding to the second conveyor belt, the labeling rack is provided with a label traction component for pulling the label at the printer onto the label peeling plate, and a waste collection device for collecting waste at the label peeling plate.

[0019] By adopting the above technical solution, the printer directly prints out the label information to be affixed to the paper box. The label peeling plate and label traction assembly on the labeling frame work together to accurately peel off the printed label and stick it to the paper box. At the same time, the waste collection device collects the waste and collects the peeled label waste paper at the same time to facilitate subsequent processing, thereby realizing automatic printing and labeling of paper boxes and improving production efficiency and label consistency.

[0020] The above-mentioned paper box paging automatic printing and labeling machine can be further configured such that: the conveying speed of the second conveyor belt is greater than the conveying speed of the first conveyor belt.

[0021] By adopting the above technical solution, the faster conveying speed of the second conveyor belt relative to the first conveyor belt provides a forward propulsion force for the paper box, which helps the paper box to remain in a separated state when passing through the paging conveyor belt. Since the speed of the second conveyor belt is faster than that of the first conveyor belt, the paper box will be quickly picked up by the second conveyor belt when it transitions from the first conveyor belt to the second conveyor belt, reducing the residence time of the paper box on the paging conveyor belt, preventing the paper boxes from stacking and thus maintaining the gap between the paper boxes, and also speeding up the speed of the paper boxes passing through the labeling area, making the labeling process faster, improving the overall efficiency of the production line, and effectively avoiding the stacking and congestion of paper boxes during the transportation process, while improving the overall labeling efficiency.
