Description

Technical Field

[0001] This utility model belongs to the field of cardboard processing technology, and more specifically, relates to a pressing device for printing cartons. Background Technology

[0002] In the printing of cardboard boxes, the boxes are glued together to improve their quality. However, when the cardboard is pressed, the glued cardboard solidifies when it enters the pressing equipment, resulting in poor pressing effect. Based on this, a pressing device for cardboard box printing is proposed.

[0003] A pressing device for printing cartons, as described in patent application CN202420528978.4, which facilitates positioning, includes a pressure plate, a vertical cover, a support plate, and a bottom cover. The support plate is fixed to the upper end of the bottom cover, and the vertical cover is connected to the upper edge of the bottom cover. A vertical cylinder is fixed to the outer wall of the vertical cover, and a top plate is provided at the upper end of the vertical cylinder. The two ends of the lower part of the top plate are fixedly connected to the upper end of the vertical cylinder. A support rod is fixed to the lower end of the top plate, and a slider is fixed to the lower end of the support rod. A sleeve is provided outside the slider, and the upper end of the sleeve is slidably connected to the support rod. The pressure plate is located on the upper part of the support plate, and the upper end of the pressure plate is fixedly connected to the lower end of the sleeve. A spring damper is connected to the lower end of the slider, and the lower end of the spring damper is fixedly connected to the upper end of the pressure plate. A guide rail is provided on the inner wall of the vertical cover. This utility model has excellent pressing effect and is easy to handle dust.

[0004] However, the aforementioned cardboard box printing pressing device, which is easy to position, is prone to problems due to dust accumulation on the pressing area, which can affect subsequent pressing and result in a lack of stability. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pressing device for printing cartons, which ensures stability during pressing.

[0006] This utility model discloses a pressing device for printing cartons, comprising an operating table; a bracket fixedly connected to the upper end of the operating table; an electric cylinder fixedly connected to the upper end of the bracket; a support plate fixedly connected to the output end of the electric cylinder; a housing slidably connected to the support plate; a pair of springs provided between the support plate and the housing; a pressure roller rotatably connected to the inner side of the housing; and a scraper fixedly connected to the inner side of the housing; the left end of the scraper abutting against the outer circumference of the pressure roller; a dust outlet opened on the upper side of the housing above the scraper; a dust collection box fixedly connected to the upper end of the bracket; a dust pump fixedly connected to the input end of the dust collection box; and the input end of the dust pump connected to the dust outlet.

[0007] Preferably, the upper end of the scraper is V-shaped; the lowermost side of the upper end of the scraper is located below the dust outlet.

[0008] Preferably, a damping rod is embedded between each spring in the support plate to buffer the impact on the pressure roller and the outer shell;

[0009] Preferably, the support plate has grooves on both sides; the two ends of the pressure roller are rotatably connected to the outer shell; the two ends of the pressure roller slide inside the grooves on both sides after passing through the outer shell.

[0010] Preferably, a hot air fan is provided on the front side of the bracket to preheat the cardboard.

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

[0012] (1) By setting up a scraper, dust collection box and dust pump, the dust on the pressure roller can be scraped off and collected, ensuring the stability during pressing; by setting up a damping rod and spring, the impact on the pressure roller is absorbed and buffered, improving the stability of pressing.

[0013] (2) By setting up a hot air fan, the residual dust on the pressed cardboard can be blown away, and the downward airflow can help the cardboard to be compacted after pressing. At the same time, the surface of the cardboard is preheated, which is convenient for subsequent printing work. Attached Figure Description

[0018] Specific Implementation Example 1: Please refer to Figure 1-3A pressing device for printing cartons includes an operating table 10; a bracket 11 is fixedly connected to the upper end of the operating table 10; an electric cylinder 12 is fixedly connected to the upper end of the bracket 11; a support plate 16 is fixedly connected to the output end of the electric cylinder 12; a housing 18 is slidably connected to the support plate 16; a pair of springs 21 are provided between the support plate 16 and the housing 18; a pressure roller 19 is rotatably connected to the inner side of the housing 18; and a scraper 22 is fixedly connected to the inner side of the housing 18; the left side end of the scraper 22 abuts against the outer circumference of the pressure roller 19. The outer casing 18 has a dust outlet 23 on the upper side of the scraper 22; the upper end of the bracket 11 is fixedly connected to the dust collection box 14; the input end of the dust collection box 14 is fixedly connected to the vacuum pump 13; the input end of the vacuum pump 13 is connected to the dust outlet 23; by setting up the scraper 22, the dust collection box 14, and the vacuum pump 13, the dust on the pressure roller 19 can be scraped off and collected, ensuring the stability during pressing; by setting up the damping rod 20 and the spring 21, the impact on the pressure roller 19 is absorbed and buffered, improving the stability of pressing.

[0019] Please see Figure 3 The upper end of the scraper 22 is V-shaped; the lowermost side of the upper end of the scraper 22 is located below the dust outlet 23.

[0020] Please see Figure 2 The support plate 16 is fitted with a damping rod 20 between each spring 21 to buffer the impact on the pressure roller 19 and the outer shell 18;

[0021] Please see Figure 2 The support plate 16 has sliding grooves 17 on both sides; the two ends of the pressure roller 19 are rotatably connected to the outer shell 18; the two ends of the pressure roller 19 pass through the outer shell 18 and slide inside the sliding grooves 17 on both sides respectively.

[0022] Please see Figure 1 A hot air fan 15 is provided on the front side of the bracket 11 to preheat the cardboard. By providing the hot air fan 15, the residual dust on the pressed cardboard can be blown away, and the downward airflow can help the cardboard to be pressed tightly. At the same time, the surface of the cardboard is preheated to facilitate subsequent printing work.

[0023] During operation, the electric cylinder 12 is activated, and its output end drives the support plate 16 to press down. Subsequently, the pressure roller 19 presses against the cardboard to press it together. During the pressing process, the outer shell 18 is subjected to the reaction force from the cardboard transmitted by the pressure roller 19. The outer shell 18 and the pressure roller 19 slide inside the support plate 16, compressing the spring 21 and the damping rod 20. If a large vibration is encountered, the liquid inside the damping rod 20 flows, which can buffer the impact on the outer shell 18.

[0024] When there is a lot of dust on the cardboard, turn on the hot air fan 15 to blow away the dust on the pressed cardboard. A lot of dust will stick to the pressure roller 19. Then the dust on the pressure roller 19 will be scraped off by the scraper 22. Since the upper end of the scraper 22 is V-shaped, the dust will be concentrated on the lower side of the dust outlet 23. Start the dust pump 13 to draw the dust into the dust collection box 14.

[0025] Since printing is required later, the hot air fan 15 generates downward airflow to press down the cardboard while heating the surface of the pressed cardboard to facilitate subsequent printing.
