Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag film processing, in particular to a printing roller placement rack. Background Art

[0002] During the production process of packaging bag film, it is necessary to print the required pattern on the surface of the film by a printing roller. In order to protect the printing roller, the printing roller is generally disassembled and placed on a placement rack when not in use. For example, the utility model patent with patent application number CN202321048166.1 discloses a printing roller placement rack, whose structure includes a base, and a placement plate is fixedly connected to the upper surface of both ends of the base. The placement plates are inclined and the upper ends of the two placement plates are fixedly connected. Two placement rods are fixedly connected to the side wall of the placement plate away from the other placement plate. The two placement rods are arranged in parallel and along the height direction of the placement plate, and a number of placement hooks are fixedly connected to the placement rods.

[0003] Before using the printing roller, the flexible resin printing plate needs to be manually pasted on the surface of the printing roller. For the convenience of pasting, it is generally operated directly on the placement rack, and the pasting is performed while rotating the printing roller. However, the above-mentioned existing structure causes sliding friction between the printing roller and the placement hook during rotation and pasting. The friction will cause wear or damage to the printing roller, which will affect printing. In addition, it is difficult to paste the printing plate. It must be pasted straight and tightly on the surface of the printing roller. Two workers are required to cooperate when pasting the printing plate. One person holds the printing plate, and the other worker aligns the printing plate with the printing roller and then rotates the printing roller to slowly paste it. This method consumes labor and is costly. Utility Model Content

[0004] The utility model aims to provide a printing roller placing rack to solve the problems raised in the above background technology.

[0005] The utility model solves the technical problem by adopting the following technical solution: a printing roller placing frame, comprising a bottom frame, a pair of supporting frames symmetrically arranged on both sides of the bottom frame, a group of card seats are respectively arranged on the two supporting frames, and the card seats on the two supporting frames are symmetrically arranged, the card seats are provided with arc-shaped card slots adapted to the end of the printing roller, a group of bearings are arranged on the card seats along the arc-shaped card slots, and the bearings protrude from the arc-shaped card slots, and a detachable lifting frame is also arranged on the supporting frames;

[0006] Furthermore, the lifting frame includes a lifting platform, and lifting support rods symmetrically arranged on both sides of the lifting platform. The two support frames are respectively provided with a group of fixing devices for fixing the lifting support rods, and each socket is correspondingly provided with a fixing device.

[0007] Furthermore, the holder includes a bottom plate, and vertical plates symmetrically arranged on both sides of the bottom plate, wherein an arc-shaped slot is arranged at the upper end of the vertical plates, and a group of bearing mounting holes are arranged on the two vertical plates along the arc-shaped slot.

[0008] In order to facilitate the disassembly and assembly of the lifting frame, the fixing device includes a fixing seat arranged on the support frame, and the fixing seat is provided with a socket adapted to the lifting support rod.

[0009] To ensure stability, the support frame is an inverted V-shaped structure, including a pair of oblique support arms inclined and symmetrically arranged on the bottom frame, horizontal support arms are arranged at the upper ends of the two oblique support arms, and a reinforcing arm is arranged between the horizontal support arm and the bottom frame.

[0010] In order to facilitate the pasting of the printing plate, the lifting platform includes a group of rollers rotatably arranged between two lifting support rods, and the two lifting support rods are provided with roller mounting holes.

[0011] To facilitate movement, a group of universal wheels with brakes are also arranged at the bottom of the bottom frame.

[0012] Beneficial effects of the utility model: Compared with the prior art, the utility model provides a group of bearings at the arc-shaped groove of the holder, and supports the end of the printing roller through the bearings, so that rolling friction is generated between the end of the printing roller and the holder when pasting the printing plate, instead of sliding friction, to reduce the friction force on the end of the printing roller, thereby reducing the friction loss on the end of the printing roller and reducing the risk of damage; the printing roller can be rotated more easily through rolling friction, which is convenient for workers to operate. At the same time, the printing plate is lifted by the lifting frame, so that the pasting process can be operated by one person instead of two people, saving labor costs; the lifting frame is easy to load and unload by fitting with the lifting support rod socket; by placing the printing plate on the roller and using rolling friction, it is convenient to drag the printing plate during pasting. In addition, the support frame adopts an inverted V-shaped structure to ensure the stability of the placement frame and prevent it from tipping over during movement.

[0020] Examples, such as Figure 1-6 As shown, a printing roller placement frame includes a bottom frame 1, a pair of support frames 2 symmetrically arranged on both sides of the bottom frame 1, a group of card seats 3 are respectively arranged on the two support frames 2, and the card seats 3 on the two support frames 2 are symmetrically arranged. The card seats 3 are provided with an arc-shaped card slot 31 adapted to the end of the printing roller, and a group of bearings 32 are arranged on the card seats 3 along the arc-shaped card slot 31, and the bearings 32 protrude from the arc-shaped card slot 31. By clamping the end of the printing roller on the bearing 32 at the arc-shaped card slot 31, rolling friction is used instead of sliding friction. When the printing roller is rotated to paste the printing plate, the friction force on the end of the printing roller can be reduced, thereby reducing the friction loss of the end of the printing roller and improving the service life. For the convenience of processing, the card seat 3 includes a bottom plate 33, and vertical plates 34 symmetrically arranged on both sides of the bottom plate 33. The upper end of the vertical plate 34 is provided with an arc-shaped card slot 31, and the two vertical plates 34 are provided with a group of bearing mounting holes 341 along the arc-shaped card slot 31. The bearings 32 can be rotatably mounted on the bearing mounting holes 341.
