[0024] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0025] Please refer to Figures 1 to 3 As shown, the present invention is a printing roller placement device, including a horizontally arranged bottom plate 1 and a bracket assembly 3 provided in the middle of the bottom plate 1. The bracket assembly 3 is used to clamp the printing roller 4. The bracket assembly 3 and the bottom plate 1 are rotatably connected through a rotating disk 35. Among them, the rotating disk 35 can be a rotating bearing in the prior art. Specifically, the rotating disk 35 is coaxially fixed on the bottom surface of the support plate 34, and the lower part of the rotating disk 35 is rotatably connected to the upper part of the bottom plate 1, so as to realize the free rotation of the bracket assembly 3 on the bottom plate 1.

[0026] Please continue to refer to Figure 3 As shown, the bracket assembly 3 includes a support plate 34, a column 33, and a plurality of fixing rods 32. The support plate 34 is horizontally arranged above the bottom plate 1. The top surface of the rotating disk 35 is fixedly connected to the bottom surface of the support plate 34. The column 33 is coaxially and vertically fixed on the top surface of the support plate 34, that is, the vertical line obtained by the central axis of the column 33 passes through the center of the bottom plate 1. A plurality of sliding grooves 38 are evenly formed in the upper part of the column 33 along the circumferential direction. The axial direction of each sliding groove 38 is parallel to the central axis of the column 33. One ends of the plurality of fixing rods 32 are respectively slidably connected to the plurality of sliding grooves 38, and the other ends of the plurality of fixing rods 32 extend radially outward along the column 33, that is, the length direction of the fixing rods 32 is perpendicular to the central axis of the column 33. Lower positioning holes 37 are evenly arranged at the lower part of the end of the fixing rod 32 far from the column 33. A plurality of lower positioning holes 36 are respectively provided on the top of the support plate 34 corresponding to the plurality of upper positioning holes 37.

[0027] Preferably, the upper positioning holes 37 and the lower positioning holes 36 respectively protrude towards the printing roller 4 along the periphery of the positioning holes to form a ring of convex rings. The convex rings can strengthen the positioning of the printing roller 4 by the positioning holes, prevent the printing roller 4 from being placed in place and tipping over, causing losses.

[0028] During implementation, one end of the cleaned printing roller 4 in the length direction is placed in the lower positioning hole 36 of the support plate 34. The height of the fixing rod 32 is adjusted as needed, and the other end of the printing roller 4 is placed in the upper positioning hole 37 of the fixing rod 32. When continuing to place the printing roller 4 as needed, the support bracket assembly 3 can be manually rotated to find an empty fixing rod 32, and the height of the fixing rod 32 is adjusted to pick up and place other printing rollers 4. By vertically placing the printing roller 4, it is possible to avoid eccentricity and deformation of the printing roller 4 that may occur due to the influence of gravity on the surface adhesive layer, affecting subsequent use. At the same time, by setting the sliding groove 38 to adjust the position of the fixing rod 32, it is possible to adapt to printing rollers 4 of different lengths.

[0029] As Figures 5 to 6 shown, a plurality of receiving cavities 331 are provided on the upper part of the column 33 along the circumferential direction. The plurality of receiving cavities 331 correspond one-to-one with the plurality of sliding grooves 38, and the plurality of receiving cavities 331 are respectively communicated with the corresponding sliding grooves 38. Specifically, the length of the receiving cavity 331 is equal to or slightly greater than the length of the sliding groove 38. One end of each fixing rod 32 close to the sliding groove 38 respectively passes through the sliding groove 38 and extends into the interior of the receiving cavity 331. Springs 39 are respectively placed in each receiving cavity 331, and the springs 39 respectively abut against the top surface of the receiving cavity 331 and the top surface of the fixing rod 32. Specifically, when the fixing rod 32 moves upward, the spring 39 will exert a downward reaction force on the fixing rod 32, thereby strengthening the positioning strength of the printing roller 4 and avoiding the overturning of the printing roller 4 due to insecure fixation, resulting in damage to the printing roller 4.

[0030] Please refer to Figures 1 to 2 shown, a protective cover 2 is further provided on the top surface of the bottom plate 1. The protective cover 2 and the bottom plate 1 form a rectangular box structure. The protective cover 2 covers the outside of the support bracket assembly 3, which can prevent water or dust in the environment, etc. One side of the protective cover 2 is open, and a box door 21 is hinged at the open part of the protective cover 2. A plurality of ventilation holes 22 are opened in the upper part of the side wall of the protective cover 2 to avoid the situation where there is still a certain amount of moisture remaining in the printing roller 4 after cleaning and cannot be discharged, resulting in aging of the rubber surface of the printing roller 4. A roller 11 for moving the bottom plate 1 is rotatably connected below the bottom plate 1, and a push rod 12 is fixedly provided on one side of the bottom plate 1. The push rod 12 facilitates moving the printing roller placement device to the required position.

[0031] Please refer to Figures 1 to 4 shown, preferably, a connecting rod 311 is fixedly provided at the top end of the column 33 of the support bracket assembly 3. The top end of the connecting rod 311 passes through the top surface of the protective cover 2 and is fixedly connected to a rotating handle 31. The connecting rod 311 is rotatably connected to the protective cover 2. During implementation, by applying a certain force to the rotating handle 31 in the horizontal direction, the rotating handle 31 can drive the support bracket assembly 3 to rotate, thereby facilitating the picking up and placing of the required printing roller 4.

[0032] When the specific implementation of the utility model is carried out, when the staff needs to place the printing roller 4, first open the box door 21, and then apply a certain force to the rotating handle 31 in the horizontal direction to rotate the idle fixing rod 32 to the side close to the box door 21. Then place one end of the cleaned printing roller 4 in the lower positioning hole 36 of the support plate 34. Next, adjust the position of the fixing rod 32 according to the length of the printing roller 4, and insert the other end of the printing roller 4 into the upper positioning hole 37, that is, adjust the distance between the fixing rod 32 and the support plate 34 to adapt to printing rollers 4 of different lengths. At this time, the spring 39 is in a compressed state. Therefore, the printing roller 4 can be firmly clamped between the fixing rod 32 and the support plate 34.

[0033] The above description is only the preferred embodiment of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
