Description

Technical Field

[0001] The utility model relates to the technical field of rubber and plastic foam board production, in particular to a rubber and plastic foam board material clamping device. Background Art

[0002] Rubber-plastic foam board insulation material products use high-performance nitrile rubber (NBR) and polyvinyl chloride (PVC) as the main raw materials, with various auxiliary materials, and are mixed, extruded, and foamed into final products through special formulas and processes.

[0003] At present, after searching, the known existing patent, the discharging machine of rubber and plastic foaming machine, application number is 201420607506.4, application date is 2014.10.20, which discloses the following technical contents: a discharging machine of rubber and plastic foaming machine, having a film feeding frame, a film feeding roller, a film feeding transmission device and a film collecting device, the film feeding motor of the film feeding transmission device drives all the film feeding rollers to rotate synchronously through chain transmission; the film collecting device includes a translation mechanism and a clamping mechanism, the translation mechanism includes a translation cylinder and a translation cylinder driven by the translation cylinder in the feeding The translation frame on the top surface of the film frame is translated back and forth, the clamping mechanism includes a fixed frame connected to the front side of the translation frame and a lifting frame driven by a lifting cylinder, a driving roller is arranged between the left and right frame edges of the fixed frame, a driven roller is arranged between the left and right frame edges of the lifting frame, and a driving roller transmission mechanism is arranged on the fixed frame, the driving roller transmission mechanism includes a roller motor arranged on the top surface of the fixed frame and a transmission shaft connected to the output shaft of the roller motor, and the transmission shaft and the main shaft of each driving roller are connected by a bevel gear pair. The present invention adopts mechanized film collection, which saves labor and time, significantly improves labor efficiency, and has low labor intensity for workers.

[0004] After the existing rubber and plastic foam board completes the compression molding operation in the mold cavity of the hydraulic press, there are two ways to discharge the material. One is the manual unloading method. The biggest disadvantage of this method is the high labor intensity. The temperature in the mold cavity of the hydraulic press is as high as 180°C or above. Workers need to wear heavy heat-insulating clothes to put the rubber and plastic foam board into the mold cavity of the hydraulic press. In the hot summer, the high temperature working environment is unbearable. Workers also need to drag the rubber and plastic foam board out of the mold cavity of the hydraulic press and place it in the designated position. If they are not careful, the rubber and plastic foam board will be placed irregularly or even fall off. It touches the workers' feet, has high labor intensity, poor working environment and certain safety hazards. Therefore, the labor cost is also relatively high. Another way is to use a conventional belt conveyor structure or a roller conveyor structure. However, the belt conveyor mechanism is not resistant to high temperatures, has a small turning radius and severe bending during transportation, and the belt needs to be replaced frequently, resulting in high production costs and frequent maintenance. The roller conveyor structure has the problem of slipping and affecting the material forming effect. The material conveyed by the roller cannot achieve the effect of single-sheet layer-by-layer sheeting, which affects the subsequent stacking operation.

[0005] Therefore, in order to solve the above problems, our technical personnel have developed a rubber and plastic foam board clamping device with a high degree of automation. It can realize the clamping operation of the material in the mold cavity of the hydraulic press, greatly reducing the labor intensity of the staff, driving the cylinder, the upper bracket and the lower bracket are close to each other, and the upper clamping block and the lower clamping block clamp the sheet material, avoiding the situation where workers use their hands to take the material in the mold cavity of the hydraulic press and consume a lot of physical energy. It can also avoid the phenomenon that the roller conveying structure transports materials and slips and affects the material molding effect. The sheet discharging and material taking operation that originally required two to three people to achieve can now be achieved by only one worker, reducing production costs and improving economic benefits.

[0022] The material clamping mechanism 1 comprises an upper bracket 104 and a lower bracket 101 which are arranged opposite to each other. Both the upper bracket 104 and the lower bracket 101 are in a comb-shaped structure. An upper clamping block 103 is arranged on the lower surface of the upper bracket 104. The upper clamping block 103 is arranged corresponding to the lower clamping block 102 on the lower bracket 101.

[0023] The lifting mechanism 2 includes a support base 203, a lifting plate 107 is symmetrically arranged on the inner wall of the support base 203, a cylinder 106 is arranged on the lifting plate 107, a movable plate 105 is arranged at the telescopic shaft end of the cylinder 106, the lower end of the movable plate 105 is connected to the upper bracket 104, and the lower end of the lifting plate 107 is connected to the lower bracket 101.

[0024] Specifically, the clamping mechanism 1 is used to clamp the sheet material in the mold cavity of the hydraulic press, driving the cylinder 106. The telescopic shaft end of the cylinder 106 drives the upper bracket 104 and the lower bracket 101 to move closer to each other, so that the upper clamping block 103 and the lower clamping block 102 can clamp the sheet material. The lifting mechanism 2 is used to lift the clamping mechanism 1, which is conducive to aligning the clamping mechanism 1 with the sheet material in the mold cavity of the hydraulic press, and providing basic conditions for the clamping mechanism 1 to clamp the material.

[0025] like Figure 3 As shown, as a preferred embodiment of the above embodiment, the contact surfaces of the upper clamping block 103 and the lower clamping block 102 with the sheet material are both provided with anti-slip grooves.

[0026] Specifically, the anti-skid pattern is configured as a grid pattern structure, which is used to increase the friction between the upper clamping block 103 and the lower clamping block 102 and the sheet material, thereby preventing the material from slipping and falling off during the clamping process.

[0027] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the above embodiment, the slider 201 provided on the side of the lifting plate 107 is matched with the guide rail 202 on the support seat 203 .

[0028] Specifically, the slider 201 and the guide rail 202 play a guiding role, thereby improving the stability and reliability of the clamping mechanism 1 during the lifting movement.

[0029] like Figure 2 As shown, as a preferred embodiment of the above embodiment, the upper portion of the lifting plate 107 is connected to a chain 204 , and one end of the chain 204 passes upward around a sprocket 205 to connect to a counterweight block, and the sprocket 205 is disposed on a rotating shaft 207 .

[0030] Specifically, when the rotating shaft 207 rotates, the sprocket 205 drives the chain 204 to move, thereby achieving the lifting and lowering movement of the lifting plate 107 along the guide rail 202 .

[0031] like Figure 2As shown, as a preferred embodiment of the above embodiment, the rotating shaft 207 is connected to the output end of the reducer, and the input end of the reducer is connected to the output shaft end of the motor 206.

[0032] Specifically, the drive motor 206 and the reducer reduce the rotation speed, thereby driving the rotating shaft 207 to rotate.

[0033] The specific working principle of the utility model is as follows: the clamping mechanism 1 is used to clamp the sheet material in the mold cavity of the hydraulic press, driving the cylinder 106. The telescopic shaft end of the cylinder 106 drives the upper bracket 104 and the lower bracket 101 to move closer to each other, so that the upper clamping block 103 and the lower clamping block 102 can clamp the sheet material. The lifting mechanism 2 is used to lift the clamping mechanism 1, which is conducive to realizing that the clamping mechanism 1 is aligned with the sheet material in the mold cavity of the hydraulic press, and provides basic conditions for the clamping operation of the clamping mechanism 1 on the material.
