Coated materials sequentially bypass the fixed roller and the floating roller, and rodless air cylinders which synchronously push the floating roller to do lifting motion so as to prolong the distance between the fixed roller and the floating roller are installed on the inner side face of the left wall plate and the inner side face of the right wall plate respectively. According to the storage rack, a balancing weight adjusting mode adopted by a traditional storage rack is omitted, the rodless air cylinder drives the floating roller to move, the distance between the floating roller and the fixed roller can be increased, the storage rack is simple in structure and long in adjusting distance, more materials can be stored when a coating machine changes rolls, and therefore the requirement for the replacement time of an air expansion shaft is met.

Description

Technical Field

[0001] The utility model relates to the technical field of coating technology, in particular to a roll-changing storage rack for a coating machine. Background Art

[0002] During the production process of the coating machine, the produced materials need to be rolled up and stored on an air shaft. After the materials are rolled up on the air shaft, a new air shaft needs to be replaced. Since the coating machine is produced continuously without stopping, a material storage rack is generally set up at the winding station so that more materials can be stored when changing rolls to meet the air shaft replacement time requirements.

[0003] In the existing material storage rack structure, the fixed roller 3 is rotatably set on the frame 1, one end of the counterweight is transmission-connected to the floating roller, the other end of the counterweight is set on the frame, the extended end of the cylinder is connected to the counterweight through a sprocket and a chain transmission, the floating roller is rotatably set on the floating arm, one end of the chain is fixed on the counterweight, the other end of the chain is wound around the sprocket and set on the floating arm, a linear guide is set on the frame, and a slider matching the linear guide is provided on the floating arm. During adjustment, the counterweight is driven up by the cylinder piston rod, and the force applied by the counterweight to the floating arm is controlled, so that the distance between the floating roller and the fixed roller is enlarged to store more materials. However, the adjustment length of this material storage rack with a counterweight is limited, and the structure is also complicated and cumbersome. Summary of the invention

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a coating machine roll changing storage rack which has a simple structure and can quickly adjust the distance between the floating roller and the fixed roller to store more materials.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a coating machine roll-changing storage rack, comprising a left wall panel and a right wall panel arranged at a distance from each other on the left and right sides, at least three fixed rollers arranged in an odd number are rotatably arranged between the inner side surfaces of the left wall panel and the right wall panel, and a floating roller whose number is one less than the number of the fixed rollers is arranged below the fixed rollers, and the coated material passes around the fixed rollers and the floating rollers in sequence, and rodless cylinders are respectively installed on the inner side surfaces of the left wall panel and the right wall panel to synchronously push the floating rollers to perform lifting movements to extend the material storage length.

[0006] Furthermore, a feeding roller is installed between the outer side of the left wall panel and the outer side of the right wall panel, and a discharging roller is installed between the inner side of the left wall panel and the inner side of the right wall panel.

[0007] Specifically, the rodless cylinder is located between two floating rollers, and floating arms are fixedly connected to both sides of the piston of the rodless cylinder, and both ends of the floating roller are rotatably supported on the corresponding floating arms.

[0008] Furthermore, cylinder seats with upper and lower spacings are fixed on the left wall panel and the right wall panel respectively, and two ends of the rodless cylinder are fixed on the corresponding cylinder seats respectively.

[0009] The beneficial effects of the utility model are as follows: the utility model cancels the counterweight adjustment method used in the traditional material storage rack, and the floating roller is driven by the rodless cylinder to move, so that the distance between the floating roller and the fixed roller can be increased. The material storage rack has a simple structure and a longer adjustment distance. More materials can be stored when the coating machine changes rolls, thereby meeting the time requirements for replacing the inflatable shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0013] In the figure: 1. left wall panel, 2. right wall panel, 3. fixed roller, 4. floating roller, 5. rodless cylinder, 6. floating arm, 7. feed roller, 8. discharge roller, 9. cylinder seat. DETAILED DESCRIPTION

[0014] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0015] like Figure 1 , Figure 2 A roll-changing storage rack for a coating machine shown in the figure comprises a left wall panel 1 and a right wall panel 2 which are arranged at a distance from each other on the left and right sides, three fixed rollers 3 which are arranged at equal intervals in sequence are provided between the inner side surfaces of the left wall panel 1 and the inner side surfaces of the right wall panel 2, two floating rollers 4 are provided below the three fixed rollers 3, a feed roller 7 is installed between the outer side of the left wall panel 1 and the outer side of the right wall panel 2, and a discharge roller 8 is installed between the inner side of the left wall panel 1 and the inner side of the right wall panel 2. The material to be coated enters from the feed roller 7, bypasses the fixed roller 3 and the floating roller 4 in sequence, and is sent out from the discharge roller 8 to the coating machine for coating treatment.

[0016] Cylinder seats 9 with upper and lower spacings are fixed on the inner side surfaces of the left wall panel 1 and the right wall panel 2, respectively. The vertical center of the cylinder seat 9 is located between the two floating rollers 4. A rodless cylinder 5 is installed between the two cylinder seats 9. Floating arms 6 are fixedly connected to both sides of the piston of the rodless cylinder 5, and both ends of the floating roller 4 are rotatably supported on the corresponding floating arms 6.

[0017] When the rodless cylinder 5 drives the two floating rollers 4 to move downward synchronously, the distance between the floating roller 4 and the fixed roller 3 can be lengthened, thereby extending the storage length of the material in the storage rack.

[0018] Since the counterweight adjustment method used in the traditional material storage rack is cancelled, the rodless cylinder 5 directly drives the floating roller 4 to move, so that the distance between the floating roller 4 and the fixed roller 3 can be increased. The material storage rack has a simple structure and a longer adjustment distance, and can store more materials when the coating machine changes rolls, thereby meeting the time requirements for replacing the air shaft.

[0019] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
