Description

Technical Field

[0001] The invention relates to the technical field of tire production, in particular to a tooling vehicle for performing curling and unwinding operations. Background Art

[0002] The collection and unwinding of the tread rubber produced by the four-composite tread extrusion line and its use in the next process are also critical basic work. The material transportation previously used a shutter-type tooling vehicle, which did not meet the requirements of the new process, and the tread rubber packaged by the shutter vehicle occupied a lot of manpower and the labor intensity of the manpower was high.

[0003] After searching, it was found that there was a previously applied utility model patent CN209455757, which had a similar working scenario to a material storage tooling winding trolley device, but there was still room for improvement in the operational continuity of the solution. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a tooling vehicle for performing curling and unwinding operations.

[0005] The present invention provides the following technical solution: comprising a large wheel and a small wheel installed at intervals, wherein both the large wheel and the small wheel are rotatably installed on a vehicle frame;

[0006] The vehicle also includes a brake device, which includes a brake wheel located at the gap between the large wheel and the small wheel, the brake wheel is installed at the end of a power arm, and a spring is connected to the upper part of the brake wheel. Under normal conditions, the brake wheel is pressed tightly between the large wheel and the small wheel under the action of the spring, and the large wheel and the small wheel remain fixed;

[0007] The middle part of the power arm is hinged on the frame. When the power arm at one end away from the brake wheel is subjected to a force opposite to that of the spring, the brake wheel releases the large wheel and the small wheel.

[0008] Furthermore, it includes an operating station, with conveying platforms arranged on both sides of the station and a space reserved in the middle for accommodating a tooling vehicle.

[0009] Furthermore, the conveying platform includes a chain driven by a motor, and the input end of the chain has a slope. When the tooling vehicle drives in, the chain with the slope contacts the bottom of the frame to guide the tooling vehicle into the workstation.

[0010] Furthermore, a driving device is provided on one side of the middle of the work station, and the driving device includes a driving wheel driven by a motor. When the tooling vehicle enters the work station, the driving wheel is in friction contact with the small wheel, thereby realizing friction drive.

[0012] Furthermore, a slow-release device is provided on the other side relative to the driving device, and the slow-release device includes a slow-release wheel. When the tooling vehicle enters the workstation, the slow-release wheel is in frictional contact with the large wheel to increase friction and reduce inertia of the large wheel.

[0013] Furthermore, one end of the slow-release wheel is driven by a cylinder to adjust the distance between the slow-release wheel and the large wheel. A tilted lifting arm is installed on one side of the slow-release wheel. When the cylinder is driven, the lifting arm is pushed forward, and the lifting arm lifts one end of the power arm, so that the brake wheel releases the large wheel and the small wheel.

[0014] Furthermore, both the large wheel and the small wheel are I-shaped wheel structures, and observation ports are opened on the sides.

[0015] Furthermore, the large wheel and the small wheel are provided in two groups, left and right, to form a double-station structure.

[0016] Furthermore, a guide roller group is arranged between the large wheel and the small wheel, the guide roller group includes an introduction roller, a first horizontal roller and a second horizontal roller arranged parallel to the first horizontal roller, a first reversing roller is arranged at the lower part between the first horizontal roller and the second horizontal roller, a second reversing roller is arranged at the output end of the second horizontal roller, and a lead-out roller is arranged at the output end of the second reversing roller;

[0017] The coiled material enters from above the inlet roller to above the first horizontal roller, then enters from below the first reversing roller to above the second horizontal roller, and then is input to the outlet roller from above the second reversing roller.

[0018] Compared with the prior art, the present invention provides a tooling vehicle for performing curling and unwinding operations, which has the following beneficial effects:

[0019] The brake device has been improved, and the braking and releasing of the brakes are controlled by a power arm. In actual implementation, the control can be achieved with the help of the linkage mechanism on the workstation, which reduces the dependence on personnel and improves the degree of automation.

[0026] 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.

[0027] Please refer to the figure, a tooling vehicle for performing curling and unwinding operations includes a large wheel 2 and a small wheel 1 installed at intervals, and the large wheel 2 and the small wheel 1 are both rotatably mounted on a vehicle frame 3;

[0028] Reference Figure 6 As shown, the brake device 20 is also included. The brake device 20 includes a brake wheel 203 located at the gap between the large wheel 2 and the small wheel 1. The brake wheel 203 is installed at the end of a power arm 201. A spring 204 is connected to the upper part of the brake wheel. Under normal conditions, the brake wheel 203 is pressed tightly between the large wheel 2 and the small wheel 1 under the action of the spring 204, and the large wheel 2 and the small wheel 1 remain fixed.

[0029] Reference Figure 3 As shown, a guide roller group 5 is arranged between the large wheel 2 and the small wheel 1, and the guide roller group 5 includes an introduction roller 56, a first horizontal roller 51, and a second horizontal roller 53 arranged parallel to the first horizontal roller 51, a first reversing roller 52 is arranged at the lower part between the first horizontal roller 51 and the second horizontal roller 53, a second reversing roller 54 is arranged at the output end of the second horizontal roller 53, and a lead-out roller 55 is arranged at the output end of the second reversing roller 54;

[0030] The coiled material enters from above the inlet roller 56 to above the first horizontal roller 51, then enters from below the first reversing roller 52 to above the second horizontal roller 53, then enters from above the second reversing roller 54 to the outlet roller 55, and finally from the tensioning roller 4 to the small wheel 1. The orderly arrangement of the rolling rollers is used to separate the padding from the material. This design can effectively prevent the extrusion caused by the separation of the material and the padding, and the arrangement of the rolling rollers can prevent the friction of the padding caused by the change of the roll diameter.

[0031] The middle part of the power arm 201 is hinged on the vehicle frame 3. When the power arm 201 at one end away from the brake wheel 203 is subjected to a force opposite to the spring 204, the brake wheel 203 releases the large wheel 2 and the small wheel 1.

[0032] It includes an operating station 10, with a conveying platform 11 on both sides of the station, and a space reserved in the middle to accommodate a tooling vehicle. Figure 4 and Figure 5As shown, the conveying platform 11 includes a chain driven by a motor, and the input end of the chain has a slope. When the tooling vehicle drives in, the sloped chain contacts the bottom of the frame to guide the tooling vehicle into the work station.

[0033] A driving device 13 is provided on one side of the middle of the workstation, and the driving device includes a driving wheel 132 driven by a motor 131. When the tooling vehicle enters the workstation, the driving wheel 132 is in friction contact with the small wheel 1 to achieve friction drive. A servo slide is installed at the bottom of the driving wheel 132 to adjust the distance between the driving wheel 132 and the small wheel 1.

[0034] A slow-release device 12 is provided on the other side of the driving device 13. The slow-release device 12 includes a slow-release wheel 122. When the tooling vehicle enters the workstation, the slow-release wheel 122 is in frictional contact with the large wheel 2 to increase friction and reduce the inertia of the large wheel 2. One end of the slow-release wheel 122 is driven by a cylinder 121 to adjust the distance between the slow-release wheel 122 and the large wheel 2. An inclined lifting arm 123 is installed on one side of the slow-release wheel 122. When the cylinder is driven, the lifting arm 123 is pushed to move forward together. The lifting arm 123 lifts one end of the power arm, so that the brake wheel 203 releases the large wheel 2 and the small wheel 1.

[0035] As mentioned above, the tooling vehicle can be used for coiling and cutting. Based on the above, the coiling station and the cutting station can be designed to have the same structure, that is, Figure 4 and Figure 5 The work vehicle itself does not need to be equipped with a driving part, and uses an external device 13 and a slow-release device 12 to achieve operation and stopping.

[0036] Specifically, when the tooling vehicle enters the workstation, the driving wheel of the driving device 13 and the slow-release wheel 122 of the slow-release device 12 move simultaneously to respectively press against the small wheel and the large wheel, and the lifting arm 123 drives the power arm at the same time to release the brake device 20, and the whole is in operation. The driving device 13 and the slow-release device 12 move in the opposite direction (i.e., leave the large wheel / small wheel) and then stop.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
