Description

Technical Field

[0001] The utility model relates to the technical field of rubber foot pad processing, in particular to a rubber foot pad grabbing device. Background Art

[0002] Flame retardant ethylene propylene diene monomer rubber (EPDM) belongs to hydrocarbon polymer material, has low oxygen index, is very easy to burn, and produces a large amount of smoke. At present, the commonly used halogen-free flame retardants for EPDM include inorganic metal compound flame retardants, silicon flame retardants, intumescent flame retardants, phosphorus flame retardants, phosphorus-nitrogen synergistic flame retardants, etc. Among these types of flame retardants, the phosphorus-nitrogen synergistic flame retardant system has the advantages of phosphorus flame retardants and nitrogen flame retardants. By adding nitrogen to the phosphorus flame retardant, it can improve thermal stability and reduce smoke generation. At the same time, it can reduce the amount of flame retardant. When this type of flame retardant is heated, a uniform carbon foam layer will be produced on its surface, which has the functions of heat insulation, heat preservation, oxygen suppression, smoke suppression and prevention of droplet phenomenon, so it has good flame retardant properties. However, there is little automation in the production of rubber products, especially the automation of large rubber foot pad products is basically blank in China. Therefore, rubber foot pad grabbing devices are used in the production of rubber foot pad products.

[0003] The ambient temperature of the existing rubber product mold is 60 to 70 degrees. The weight of the agricultural machinery foot pad is relatively large. In addition, the rubber and mold have high adsorption force, so the operator's physical load is quite high. Therefore, the operator is very tired. The present invention solves the problem of using a machine to replace people to perform the heavy demoulding work. Utility Model Content

[0020] Example

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A rubber foot pad grabbing device comprises a cylinder connecting seat 2 and a fixed frame 3. The cylinder connecting seat 2 is installed and connected to the top position of the fixed frame 3. A limit block 5 is arranged in the middle of the upper end of the cylinder connecting seat 2. The inner side of the limit block 5 is provided with a cylinder limit rod 7 on the cylinder connecting seat 2. The upper end of the fixed frame 3 is provided with mounting holes 8 at the corners around the upper end. A driving cylinder 1 is arranged at the top of the cylinder connecting seat 2. A limit hole 6 is arranged around the outer side of the fixed frame 3. A grabbing assembly 4 is arranged at the lower inner end of the fixed frame 3. During use, when the driving rod of the driving cylinder 1 is pushed out, the clamping claw head 44 in the grabbing assembly 4 surrounds the connecting pin 4. 1 rotates inwards, so that the distance between the left and right clamping claw heads 44 gradually becomes smaller to clamp the object. When the clamping claw head 44 clamps the object and lifts it upward, the tension makes the clamping grip tighter and tighter. The mouth of the clamping claw head 44 has teeth to prevent slipping, so it is not easy to slip during the process of clamping and dragging the product. When the driving cylinder 1 is withdrawn, the left and right clamping claw heads 44 rotate outwards around the connecting pin 41 on the clamping grip, so that the distance between the left and right clamping claw heads 44 gradually becomes larger, the clamping mouth is loosened, and the product slides off. The overall structure of the device is simple, the versatility is strong, the grasping process is stable, the risk of tearing is low, and the degree of automation is high. It effectively fills the gap in the domestic large-scale automatic demoulding mechanism of rubber foot pads.

[0022] In the utility model, the fixed frame 3 and the grabbing assembly 4 are connected and installed by a sleeve connection, and the grabbing assembly 4 is connected to the inner lower end position of the fixed frame 3. The grabbing assembly 4 includes a connecting pin 41, a chain plate 42, a stainless steel block 43 and a clamping claw head 44. Chain plates 42 are arranged on both sides of the outer end of the stainless steel block 43, and a connecting pin 41 is arranged at the connection between the chain plate 42 and the stainless steel block 43. The clamping claw head 44 is arranged on both sides of the lower end of the stainless steel block 43. The stainless steel block 43 is connected to the fixed frame 3. During use, when the driving rod of the driving cylinder 1 is pushed out, the clamping claw head 44 in the grabbing assembly 4 rotates inward around the connecting pin 41. The rotation movement causes the distance between the left and right clamping claw heads 44 to gradually decrease to clamp the object. When the clamping claw heads 44 clamp the object and lift it upward, the tension makes the clamping grip tighter and tighter. The teeth at the mouth of the clamping claw heads 44 have an anti-slip effect, so it is not easy to slip during the process of clamping and dragging the product. When the driving cylinder 1 is withdrawn, the left and right clamping claw heads 44 rotate outward around the connecting pin 41 on the clamping grip, causing the distance between the left and right clamping claw heads 44 to gradually increase, the clamping mouth is loosened, and the product slides off. The device has a simple overall structure, strong versatility, a smooth grasping process, a low risk of tearing, and a high degree of automation, which effectively fills the gap in the domestic large-scale automatic demoulding mechanism of rubber foot pads.

[0023] In the present invention, the cylinder connection base 2 and the fixed frame 3 are connected and installed by riveting, and the cylinder connection base 2 is connected to the top position of the fixed frame 3.

[0024] In the utility model, the driving cylinder 1 and the cylinder connecting seat 2 are fixed by the cylinder limiting rod 7. When the driving cylinder 1 is installed, it is rotated and tightened with the cylinder limiting rod 7 on the inner side of the cylinder connecting seat 2, so that it is not easy to loosen during use. The threaded rotation method is used for connection and installation, which makes disassembly and assembly convenient.

[0025] In the utility model, the cylinder connecting seat 2, the fixed frame 3, the grabbing assembly 4, the limit block 5 and the cylinder limit rod 7 are all made of stainless steel. The cylinder connecting seat 2, the fixed frame 3, the grabbing assembly 4, the limit block 5 and the cylinder limit rod 7 are made of stainless steel so that they will not rust when placed and will not affect their sensitivity when used.

[0026] Working principle: During use, when the driving rod of the driving cylinder 1 is pushed out, the claw head 44 in the grabbing assembly 4 rotates inward around the connecting pin 41, so that the distance between the left and right claw heads 44 gradually becomes smaller to clamp the object. When the claw head 44 clamps the object and lifts it upward, the tension makes the clamping tighter and tighter, and the mouth of the claw head 44 has teeth to prevent slipping, so it is not easy to slip during the process of clamping and dragging the product. When the driving cylinder 1 is retracted, the claw heads 44 on the left and right sides rotate outward around the connecting pin 41 on the clamping, so that the distance between the left and right claw heads 44 gradually becomes larger, the clamping mouth is loosened, and the product slips off. The overall structure of the device is simple, the versatility is strong, the grasping process is smooth, the risk of tearing is low, and the degree of automation is high. It effectively fills the gap in the domestic large-scale automatic demoulding mechanism of rubber foot pads.
