Description

Technical Field

[0001] This utility model relates to the field of packaging and printing, specifically to a packaging and printing roller assembly with a cleaning mechanism. Background Technology

[0002] Printing rollers are one of the accessories of printing and packaging machines. After long-term use, pigment residue remains on the surface of the printing rollers. Because the pigment is sticky, it is easy to attract impurities. Therefore, the surface of the printing rollers needs to be cleaned regularly to ensure that the printed patterns meet the requirements.

[0003] Most existing printing roller assemblies are fixed designs. When cleaning the printing rollers, it is necessary to remove them from the packaging equipment and then reinstall them after cleaning. This results in cumbersome installation steps and time-consuming cleaning. Utility Model Content

[0008] The adjustment mechanism includes a cylinder, a piston rod is installed at the output end of the cylinder, a suspension is connected to the other end of the piston rod, a force arm is provided at the end of the suspension, an adjustment shaft seat is installed in the through hole of the suspension and the force arm, and a printing roller is clamped in the through hole of the force arm.

[0009] The cleaning box includes an upper cleaning box and a lower cleaning box arranged symmetrically. The upper cleaning box and the lower cleaning box have a bolt plate with a bolt hole formed on their adjacent end faces. A bolt rod is screwed into the bolt plate.

[0010] The cleaning mechanism includes a brush holder disposed inside the lower cleaning box, on which a brush is attached to the printing roller. The upper cleaning box is also provided with a spray frame, on which nozzles facing the opening of the printing roller are installed at intervals.

[0011] Preferably, a transmission gap is provided between the idler roller and the printing roller, and the printing roller is rotated by an external drive device.

[0012] Preferably, the upper cleaning box has a raised plate formed on it, and the lower cleaning box has a slot that matches it. The raised plate and the slot are inserted and combined.

[0013] Preferably, the printing roller to be cleaned is held inside the cleaning box formed by the closed upper cleaning box and the lower cleaning box.

[0014] Preferably, the brush holder is provided in three sets, with two sets symmetrically arranged in the lower cleaning box and the other set arranged in the upper cleaning box.

[0015] Preferably, the bottom of the convex plate is provided with a water leakage hole, which is connected to a water storage box with an internal cavity.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] 1. When cleaning the printing roller is required, the piston rod at the output end is extended by the cylinder to lift the suspension and lever arm upward. By adjusting the rotation of the bearing seat, the printing roller is exposed to an open space. The printing roller can be cleaned in conjunction with the cleaning box without disassembling it, thus improving cleaning efficiency.

[0018] 2. During the cleaning process, the tilted nozzles spray clean water or cleaning solution onto the printing rollers. The brushes on the brush holder work together at multiple angles to clean the surface of the printing rollers, improving the cleaning effect. The cleaning box is in a fixed state, and the printing is controlled by the rotation of the drive device inside the packaging equipment. The power for the cleaning process comes from the packaging equipment itself, so there is no need to add power equipment. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figure 1-4 As shown, the present invention proposes a packaging printing roller assembly with a cleaning mechanism, which includes symmetrically arranged roller frames 11, and rollers 12 are placed in the slots of the roller frames 11.

[0027] The adjustment mechanism includes a cylinder 21, a piston rod 22 is installed at the output end of the cylinder 21, a suspension 23 is connected to the other end of the piston rod 22, a force arm 25 is provided at the end of the suspension 23, an adjustment bearing seat 24 is installed in the through hole of the suspension 23 and the force arm 25, and a printing roller 26 is clamped in the through hole of the force arm 25.

[0028] The cleaning box includes an upper cleaning box 31 and a lower cleaning box 32 arranged symmetrically. The upper cleaning box 31 and the lower cleaning box 32 have a bolt plate 35 with a bolt hole formed on their adjacent end faces. A bolt rod 36 is screwed into the bolt plate 35.

[0029] The cleaning mechanism includes a brush holder 41 located inside the lower cleaning box 32, on which a brush 42 is attached to the printing roller 26. The upper cleaning box 31 also has a spray rack 43, on which nozzles 44 are installed at intervals facing the printing roller 26.

[0030] It should be noted that a transmission gap is left between the idler roller 12 and the printing roller 26 for the printing material to pass through. The printing roller 26 is controlled by an external drive device to rotate and print patterns and colors on the surface of the printing material.

[0031] In one embodiment, when the printing roller 26 needs to be cleaned, the piston rod 22 at the output end is extended by the cylinder 21, which lifts the suspension 23 and the lever arm 25 upward. By adjusting the rotation of the bearing seat 24, the printing roller 26 is exposed to an open space. The cleaning work can be carried out with the cleaning box without disassembling the printing roller 26, thus improving the cleaning efficiency.

[0032] As an example of a cleaning box assembly: the upper cleaning box 31 has a raised plate 33 formed on it, and the lower cleaning box 32 has a matching slot 34. The raised plate 33 and the slot 34 are inserted and combined. The printing roller 26 to be cleaned is clamped by the upper cleaning box 31 and the lower cleaning box 32. The raised plate 33 is inserted into the slot 34 for initial positioning. The cleaning box is assembled and reinforced by the screw connection of the external bolt plate 35 and bolt rod 36.

[0033] As an example of cleaning the printing roller 26: three sets of brush holders 41 are provided, two sets are symmetrically arranged in the convex plate 33, and the other set is arranged in the upper cleaning box 31. The three sets of brush holders 41 are located at different angles. The inclined nozzles 44 spray clean water or cleaning solution onto the printing roller 26. The surface of the printing roller 26 is cleaned by the multi-angle cooperation of the brushes 42 on the brush holders 41. During the cleaning process, the cleaning box is in a fixed state, and the printing roller 26 is controlled by the drive device inside the packaging equipment to rotate. The power for the cleaning process comes from the packaging equipment itself, and no additional power equipment is required.

[0034] To facilitate the collection of wastewater during the cleaning process, a drainage hole is provided at the bottom of the convex plate 33, which is connected to a water storage box 5 with an internal cavity.

[0035] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
