Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing, and in particular relates to a carton color printing and laminating machine which is convenient for cleaning dust particles. Background Art

[0002] The carton laminating machine uses heat and pressure to tightly fit the film to the carton. Usually the film is preheated first, and then put into contact with the carton under a certain pressure to make the film firmly adhere to the surface of the carton.

[0003] Since cartons come in different sizes and sizes, they need to be transported to a laminating machine using a conveying device before laminating. Cartons are usually color-printed or printed before laminating. After being stacked and transported, dust and particulate matter will adhere to their surface. Therefore, the surface of the cartons needs to be cleaned before laminating.

[0004] However, most of the conveying devices on the existing laminating machines do not have a cleaning mechanism. Cartons often pass through the conveying device directly into the laminating machine for lamination. After lamination, bubbles or loose adhesion between the film and the carton often occur. On the one hand, this affects the quality and appearance of the carton lamination, and on the other hand, it also increases the probability of defective carton lamination.

[0005] Therefore, design a carton color printing and laminating machine that is convenient to clean dust particles to improve above-mentioned technical defects. Utility Model Content

DETAILED DESCRIPTION

[0024] This specific embodiment is a carton color printing and laminating machine that is easy to clean dust particles. Its structural diagram is as follows Figure 1-Figure 5 As shown, it includes several hollow rollers 1, and the hollow rollers 1 are distributed in two rows, the upper hollow rollers 1 can select a specified number according to actual needs, or they can not be installed on the upper side. The side wall of the hollow roller 1 is provided with several micropores 3, and the diameter of the micropores 3 is relatively small to avoid the aperture being too large and the suction being too large, which affects the normal transportation of the cartons. The two ends of the hollow roller 1 are respectively fixedly connected with a rotating shaft 4, and the right rotating shaft 4 is hollow. A bracket 13 is provided on the lower side of the hollow roller 1, and several support plates 2 are fixedly connected to the top surface of the bracket 13. The other end of the rotating shaft 4 is rotatably connected to the support plates 2 on both sides, and the right end of the right rotating shaft 4 is connected to the same negative pressure pipe 6, and a filter component is provided between the right rotating shaft 4 and the negative pressure pipe 6.

[0025] like Figure 4 and Figure 5 As shown, the filter assembly includes an annular plate 7 rotatably connected to the end face of the right rotating shaft 4, a collar 8 is provided on the right end face of the annular plate 7, a hose 5 is fixedly connected to the end face of the collar 8, the hose 5 is connected to the negative pressure pipe 6, the annular plate 7 and the collar 8 are both stepped structures, the side walls of the annular plate 7 and the collar 8 are threadedly connected with a screw sleeve 9, and a filter screen 10 is assembled between the annular plate 7 and the collar 8.

[0026] Among them, when the filter 10 needs to be taken out for cleaning, first rotate the screw sleeve 9, remove the ring 8, and then take out the filter 10 for cleaning to avoid excessive impurities adhering to the filter 10 and affecting the dust collection effect; in addition, the filter 10 can be replaced with a filter 10 formed by a net bag to increase the impurity storage space.

[0027] like Figure 5 As shown, a sealing block 11 is fixedly connected to the end face of the annular plate 7, and an annular groove 12 is formed on the end face of the right rotating shaft 4. The sealing block 11 is rotatably connected to the annular groove 12. The provision of the sealing block 11 and the annular groove 12 not only serves to limit the position of the annular plate 7, so that when the rotating shaft 4 rotates, the annular plate 7 and the collar 8 will not rotate. On the other hand, they also provide a sealing function to prevent gas leakage that would affect the sealing effect. In addition, the sealing block 11 and the annular groove 12 can also be configured in other shapes, such as T-shaped, L-shaped, etc.

[0028] like Figure 2As shown, the left end face of the rotating shaft 4 is fixedly connected to a sheave 14, and a belt 15 is connected between the sheaves 14. The belts 15 are staggered. The sheaves 14 and belts 15 can drive the multiple hollow rollers 1 to rotate synchronously. The upper hollow roller 1 can rotate by friction due to the movement of the carton.

[0029] like Figure 1 As shown, the right side wall of the bracket 13 is fixedly connected to a mounting plate, on which a fan 16 is mounted, and the air inlet end of the fan 16 is connected to the negative pressure pipe 6. Driven by the fan 16, it has the characteristics of simple structure, low energy consumption, and flexible use.

[0030] like Figure 1 and Figure 2 As shown, the side walls of the hollow roller 1 are provided with a plurality of transverse grooves 17, which are connected to the micropores 3. The transverse grooves 17 can increase the uniformity of dust collection and prevent cartons from being adsorbed, thereby not affecting the conveying performance of the cartons.

[0031] Working principle: First, place this device on the feed side of the laminating machine for use. When the carton needs to be laminated, first use an external motor to drive one of the hollow rollers 1 to rotate, and use the cooperation of the groove wheel 14 and the belt 15 to drive the other hollow rollers 1 to rotate synchronously. Then place the carton on the hollow roller 1 and convey it as the hollow roller 1 rotates. At the same time, start the fan 16, and the fan 16 generates negative pressure in the negative pressure pipe 6. The outside air enters the hollow roller 1 through the micropores 3, and uses suction to clean the dust and particulate impurities adhering to the carton, so as to achieve the purpose of efficient cleaning and effectively improve the lamination quality of the carton.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
