Roller disassembly device for coating machine

Abstract

A roller disassembly device for a coating machine has a support plate structure that can adjust the tilt angle and an adjustment rod structure that can disengage and cooperate with a key slot on a rotating sleeve, so that the support plate can be adjusted separately and the rotating sleeve can be driven to rotate together. When the support plate is adjusted separately, the tilt angle of the support plate can be adaptively adjusted to adapt to the height of the roller on different equipment; when the support plate rotates together with the rotating sleeve, the support plate is connected to the lever mechanism through a push rod. At this time, after the support plate bears the weight of the roller, it will push a clamping column to press on the ground through the lever. The heavier the roller, the greater the corresponding clamping force of the clamping column on the ground, which can greatly enhance the friction, avoid sliding of the entire vehicle body, and increase the stability of the device.

[0002] At present, there are many kinds of coating methods for coating machines, the main coating methods include direct gravure coating, three-roller offset transfer coating, five-roller solvent-free coating, etc.; most of the coating machines currently used can realize the function of using multiple rollers, which greatly improves the application scope of the coating machine, while reducing the increase in infrastructure costs caused by one machine for one use in the actual production process, thereby effectively reducing the price of the product; this kind of one-machine-multiple-purpose equipment needs to replace the roller according to different application scenarios during use.

[0003] In addition, most of the rollers of coating machines now need regular maintenance. During maintenance, the rollers need to be removed and the surface of the rollers needs to be processed. Now, whether it is a multi-purpose machine or other models, during the replacement of rollers, due to the heavy weight of the rollers, in order to avoid bumps and damage to the roller surface, the rollers generally need to be supported during the disassembly process. The commonly used method is to use a crane to hang the outer surface of the roller with a soft rope for support.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] By the attached Figure 1-9It can be seen that the present invention provides a roller disassembly device for a coating machine, and its technical solution for solving the technical problem includes a body 1, a fixed shaft 2 is provided at the lower right side of the body 1, a support plate 3 is hinged on the fixed shaft 2, the free end of the support plate 3 is higher than the hinged end, and the free end of the support plate 3 is always higher than the hinged end no matter how it is adjusted, so that the disassembled roller can fall on the support plate 3 to avoid the risk of sliding back; a plurality of sliders 4 are arranged in an arranged manner on the support plate 3, and a first spring 5 is connected between adjacent sliders 4; the arrangement and combination of multiple sliders 4 and the design of multiple groups of first springs 5 ​​can well increase the buffering and supporting effect of the roller; an arc-shaped bracket 6 is fixedly provided on the slider 4 located on the far right side of the support plate 3, and the concave surface of the arc-shaped bracket 6 faces the free end of the support plate 3. The design of the arc-shaped bracket 6 can well adapt to the circular structure of the roller, and at the same time, in specific use, the arc-shaped bracket The concave surface of 6 can be covered with an elastic layer to better protect the roller; a rotating sleeve 7 is provided on the fixed shaft 2. In the initial state, the support plate 3 is not in contact with the rotating sleeve 7. A plurality of key grooves 9 distributed along the circumference are provided on the outer edge surface of the rotating sleeve 7. An adjusting rod 8 is provided at one end of the support plate 3 close to the fixed shaft 2. The adjusting rod 8 and the support plate 3 are slidingly connected in the front-to-back direction. The front-to-back sliding of the adjusting rod 8 can realize the mutual cooperation between the adjusting rod 8 and the key groove 9. The adjusting rod 8 is inserted into the key groove 9. The adjusting rod 8 and the rotating sleeve 7 both exist as a conversion part to realize the independent adjustment of the support plate 3 and the association with the lever mechanism; the support plate 3 can drive the rotation of the rotating sleeve 7 through the cooperation of the key groove 9 and the adjusting rod 8. A pushing rod is provided on the outer edge of the rotating sleeve 7. A lever 10 is provided on the body 1. One end of the lever 10 is placed on the upper part of the push rod, and a pressing column 11 that can move up and down is provided at the lower part of the other end of the lever 10.

[0034] In the present invention, a key block facing the rotating sleeve 7 is provided on the adjusting rod 8, and inclined surfaces are respectively provided at the front and rear ends of the key block. The entire key block is a shuttle-shaped structure in the front and rear directions. This shape design can facilitate the adjustment of the conversion member. The adjusting rod 8 can facilitate the key block to be inserted into the key slot of the rotating sleeve 7 through the shuttle-shaped structure, which plays a guiding role; at the same time, the key slots 9 on the rotating sleeve 7 are distributed in the upper half of the rotating sleeve 7, and the key slots 9 are evenly distributed on the outer edge of the rotating sleeve 7; the distribution number and angle of the key slots 9 can control the different initial angles of the support plate 3, thereby ensuring better adaptability.

[0035] In the present invention, one end of the lever 10 placed on the upper part of the clamping column 11 is designed as a cam structure, and a second spring 12 is connected between the clamping column 11 and the vehicle body 1. Under the action of the second spring 12, the outer edge surface of the cam always keeps in contact with the upper end surface of the clamping column 11, which can well adapt to the slight movement of the support plate 3; at the same time, the distance between the end of the lever 10 placed on the upper part of the clamping column 11 and the hinge point is greater than the distance between the other end of the lever 10 and the contact point of the push rod and the hinge point, which will form a laborious lever structure, and the slight rotation of the push rod will amplify the up and down movement distance of the clamping column through the lever mechanism, which can further increase the friction effect and increase the stability of the device.

[0036] The end of the push rod that contacts the lever 10 is a spherical structure, and the design of the spherical structure can well ensure the contact effect with the lever without any jamming.

[0037] A counterweight 13 is provided on the outer wall of the vehicle body 1 on the opposite side of the support plate 3. Because the longer the support plate 3 is designed, the greater the vertical downward force it receives at the right end after receiving the roller, the overall device will have a tendency to tilt upward to the left and easily fall over. A heavier counterweight is set on the left side of the vehicle body 1 to balance the torque and maintain stability.

[0038] In the present invention, a sliding groove is provided inside the support plate 3, the slider 4 is installed in the sliding groove, a through groove is opened on the upper end surface of the support plate 3, the slider 4 is connected to the arc bracket 6 through a connecting plate, and an I-shaped structure is formed between the arc bracket 6 and the slider 4; the slider 4 is installed inside the support plate 3, so that all the first springs 5 ​​and the slider 4 are hidden inside the support plate 3, and only the arc bracket 6 is connected to the upper end surface of the support plate 3 through the connecting plate to achieve support for the roller.

[0039] The lower end of the clamping column 11 passes through the bottom wall of the vehicle body 1 , and the lower end surface of the clamping column 11 is provided with an anti-skid layer 14 to better increase the friction force.

[0040] When the present invention is used, it is divided into two states, which are carried out successively. First, the device is moved as a whole to the vicinity of the coating machine where the roller needs to be disassembled. Specifically, it can be driven by the wheels designed at the lower part of the vehicle body. When the device is moved to the vicinity of the coating machine, the key block on the adjusting rod 8 is not in contact with the key slot 9 on the rotating sleeve 7. At this time, the operator can adjust the inclination angle of the support plate alone, so that the end of the support plate 3 can reach different heights, which can realize the disassembly assistance of rollers of different heights of different equipment; when the support plate 3 is adjusted to the specified position, at this time, the adjusting rod 8 is first adjusted to insert the key block into the key slot 9, The connection between the support plate 3 and the rotating sleeve 7 is realized; at this time, the connecting parts of the roller can be disassembled. When the roller is disassembled, it will slide downward along the support plate 3 under the action of its own gravity and rest on the concave surface of the arc-shaped bracket 6. Due to the design of the slider and the first spring, the buffering effect on the roller can be increased; at the same time, after the support plate 3 is affected by gravity, it tends to rotate downward. At this time, the pushing rod on the rotating sleeve 7 will push the right end of the lever to rotate upward, and then the other end of the lever can swing downward, which can push the clamping column 11 to move downward and finally rest on the ground, thereby increasing the friction against the ground and increasing the stability of the device.
