Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a cutting device and tire processing equipment having the same. Background Art

[0002] At present, a solid tire is a solid tire assembled on a pneumatic tire rim. Its carcass is made of solid rubber, has no cord as a skeleton, and does not need to be inflated. Since solid tires have the disadvantages of thick carcass and poor elasticity, the heat generated during deformation (load bearing) is difficult to dissipate. Therefore, side holes are often designed on the side of the tire to improve the cushioning and heat dissipation performance of the solid tire. The manufacturing process of solid tires generally adopts a winding method for molding, that is, the rubber sheet hot-mixed on the mixing mill is wound on the molding drum in turn to form a base rubber, intermediate rubber and tread rubber with a certain thickness to form a tire blank with a rectangular cross-section, and then formed once by the molding drum. In fact, the above molding process is not applicable to all solid tires. For example, the solid tires used for skid loaders have a small aspect ratio, a deep tread and side holes on the sidewalls. During the actual molding process, due to the large difference between the tire structure and the structure of the solid tire (the structure of the wheel mold cavity) (that is, the outer surface of the tire with a rectangular cross-section cannot stably fit with the cavity wall of the wheel mold cavity), and the amount of change in the tire mouth and sidewall during the molding process (due to the side holes), the rubber (rubber sheet) of the tire is prone to large flow in the wheel mold cavity during the extrusion and molding process. At this time, the position distribution of the wire ring and the rubber layers inside the tire is difficult to predict. If the wire ring is skewed during the rubber flow, it will increase the difficulty of assembling the solid tire and the rim. If the intermediate rubber flows into the base rubber position, it will cause insufficient hardness between the solid tire and the rim, which is easy to cause slipping, loosening of the wire ring and the base rubber, and other damage problems, seriously affecting the quality of the finished tire.

[0003] In the existing technology, technicians have developed a new processing technology, that is, during the production process of the tire blank, the width of the rubber sheet is adjusted to form a tire blank shape that is close to the shape of the tire mold (wheel mold cavity), thereby avoiding problems such as large tire deformation, difficulty in mold installation, and skewed position of the wire ring caused by excessive width difference between the rubber layers in the tire blank.

[0004] However, the size of the film heat-mixed by the conventional open mixing mill is fixed and cannot be adjusted accordingly. Utility Model Content

[0025] In order to solve the problem that the size of the film on the tire processing equipment in the prior art cannot be adjusted, the present application provides a cutting device and tire processing equipment having the same.

[0026] like Figure 1As shown, the cutting device is mounted on a conveyor for conveying material to be processed and includes a frame 10, a tool assembly 20, a first drive mechanism 30, and a second drive mechanism 40. The frame 10 has a movable portion 11, which has a receiving space 111. The tool assembly 20 is movably mounted on the frame 10, with at least a portion of the tool assembly 20 located within the receiving space 111, so that the movable portion 11 can drive the tool assembly 20 to move. The tool assembly 20 includes a tool holder 21 and a tool 22, which is rotatably mounted on the tool holder 21. The first drive mechanism 30 is drivably connected to the movable portion 11. The first drive mechanism 30 drives the tool assembly 20 by driving the movable portion 11 to adjust the processing position of the tool 22 on the material to be processed. The second drive mechanism 40 is drivably connected to the tool holder 21. The second drive mechanism 40 drives the tool holder 21 to rotate the tool 22, thereby driving the tool 22 into or out of contact with the material to be processed.

[0027] Applying the technical solution of this embodiment, the cutting device is arranged on a conveying device for conveying materials to be processed and includes a frame 10. The movable part 11 of the frame 10 has an accommodating space 111. The tool assembly 20 is movably arranged on the frame 10, and at least part of the tool assembly 20 is located in the accommodating space 111, so as to drive the tool assembly 20 to move through the movable part 11. The tool 22 of the tool assembly 20 is rotatably arranged on the tool holder 21, and the tool holder 21 is rotatably arranged. The first drive device 30 is driven and connected to the movable part 11 to drive the tool assembly 20 to move by driving the movable part 11 to adjust the processing position of the tool 22 on the material to be processed. The second drive device 40 is driven and connected to the tool holder 21 to drive the tool 22 to rotate by driving the tool holder 21 to drive the tool 22 to contact or separate from the material to be processed. In this way, the cutting device installed on the conveyor device can actually cut the material to be processed during transportation. Specifically, when the second drive device 40 drives the tool holder 21 to rotate the tool 22 until it contacts the material to be processed, the tool 22 can passively cut the material to be processed during transportation. By driving the movable portion 11 and the tool assembly 20 through the first drive device 30, the cutting position of the tool 22 can be adjusted to adjust the cutting size of the material to be processed, thereby resolving the problem of the film size being unable to be adjusted on conventional tire processing equipment. Furthermore, this arrangement allows the specific structure of the tire blank formed by winding the material to be processed to be adjusted accordingly, thereby improving the tire molding quality.

[0028] In this embodiment, the material to be processed is rubber (film).

[0029] In this embodiment, the cutter 22 is a disc cutter. The cutter 22 does not need to be actively driven to rotate. It can be passively rotated during the conveying process of the material to be processed to achieve cutting of the material to be processed.

[0030] Specifically, the contact between the disc cutter and the material to be processed is close to one point, the force is smaller, and the cutting edge is not easily damaged, thereby extending the service life of the tool.

[0031] Optionally, there are at least two tool assemblies 20 and at least two movable parts 11, and the at least two tool assemblies 20 and the at least two movable parts 11 are arranged in a one-to-one correspondence. The first drive device 30 is driven and connected to the at least two movable parts 11 to drive the at least two movable parts 11 to move toward or away from each other. In this way, the above arrangement can, on the one hand, achieve synchronous driving of the at least two tool assemblies 20 to ensure that the cut material to be processed has a high degree of dimensional symmetry, thereby adapting to the structure of the tire blank and further improving the molding quality of the tire blank; on the other hand, it can achieve synchronous cutting of both sides of the material to be processed, thereby reducing the processing steps of the material to be processed and improving processing efficiency. At the same time, the above arrangement also makes the number of tool assemblies 20 to be set more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0032] In this embodiment, there are two tool assemblies 20 and two movable parts 11 , and the two tool assemblies 20 and the two movable parts 11 are provided in a one-to-one correspondence.

[0033] like Figure 1 As shown, the cutting device further includes a transmission structure 50, through which the first drive device 30 is drivenly connected to at least two movable parts 11. The transmission structure 50 is a bidirectional lead screw. Thus, by providing the transmission structure 50, the first drive device 30 can be drivenly connected to at least two movable parts 11 simultaneously, thereby reducing the number of first drive devices 30 required and thereby lowering the manufacturing cost of the cutting device. Furthermore, this arrangement also achieves greater drive synchronization between the at least two movable parts 11, further improving the cutting quality of the cutting device.

[0034] In this embodiment, two bearing seats 70 for supporting the bidirectional screw are further provided on the frame 10. The two ends of the bidirectional screw are respectively passed through the bearings of the two bearing seats 70 to ensure that the bidirectional screw has high rotational stability.

[0035] In this embodiment, the first driving device 30 is a servo motor.

[0036] In this embodiment, a speed reducer is further provided between the first driving device 30 and the bidirectional lead screw.

[0037] In this embodiment, the thread on the bidirectional lead screw is a T-shaped thread.

[0038] In other embodiments not shown in the accompanying drawings, there are at least two first drive devices, each corresponding to the at least two movable parts. This arrangement allows for greater flexibility and variety in the number of first drive devices to accommodate different operating conditions and usage requirements. Furthermore, it eliminates the need for a transmission structure on the frame, thereby reducing the size of the cutting device and facilitating a compact design.

[0039] like Figure 1 As shown, the transmission structure 50 is rotatably mounted on the frame 10, and the movable portion 11 has a first through-hole 112 and a second through-hole 113 spaced apart from each other. The first through-hole 112 is for receiving the transmission structure 50. The cutting device further includes a guide structure 60 mounted on the frame 10, at least a portion of which is disposed within the second through-hole 113 to guide the movable portion 11 during movement. In this manner, the guide structure 60 not only guides the direction of movement of the movable portion 11 to enhance its stability, but also prevents rotation of the movable portion 11, enabling the movable portion 11 to cooperate with the bidirectional lead screw and achieve its movement.

[0040] In this embodiment, the guide structure 60 is rod-shaped.

[0041] In this embodiment, there are two second through-holes 113 and two guide structures 60. The two second through-holes 113 are respectively located on both sides of the first through-hole 112, and the two guide structures 60 are respectively located on both sides of the bidirectional screw to balance the load.

[0042] like Figure 1As shown, the movable portion 11 includes at least two plate-like structures 114 and a connecting tube 115. The at least two plate-like structures 114 are arranged relative to each other to surround and form a receiving space 111. The connecting tube 115 is penetrated on the at least two plate-like structures 114 to form a first penetration hole 112 through the inner hole of the connecting tube 115. Each plate-like structure 114 is provided with a through hole to form a second penetration hole 113 through the through hole. Among them, the tool 22 is provided at one end of the tool holder 21, and the other end of the tool holder 21 has a sleeve portion 212. The sleeve portion 212 is rotatably provided on the guide structure 60 and is located between the at least two plate-like structures 114. In this way, the provision of the connecting tube 115 can increase the matching area between the movable portion 11 and the bidirectional screw, thereby improving the matching reliability between the movable portion 11 and the bidirectional screw. At the same time, during the movement of the movable portion 11, the plate-like structure 114 can stop the sleeve portion 212, thereby driving the sleeve portion 212 (the tool holder 21) to move. At the same time, the above arrangement also makes the structure of the movable portion 11 simpler, which is conducive to achieving a lightweight design of the movable portion 11.

[0043] In this embodiment, the rotation axis of the tool holder 21 is coaxial with the guide structure 60 .

[0044] Optionally, each plate-like structure 114 further has a mounting hole 1141. At least a portion of the second drive device 40 is disposed within the accommodating space 111 and is rotatably connected to the movable portion 11 via the mounting hole 1141. The second drive device 40 drives a cylinder; one of the cylinder body and piston rod of the second drive device 40 is rotatably connected to the movable portion 11, and the other of the cylinder body and piston rod of the second drive device 40 is rotatably connected to the tool holder 21. Thus, during the process of the second drive device 40 driving the tool holder 21 to rotate, the tool holder 21 can further adaptively rotate about the connection between the second drive device 40 and the tool holder 21, thereby ensuring high driving stability of the second drive device 40.

[0045] Optionally, the blade holder 21 is provided with a connection hole 211 for rotatably connecting to the second drive device 40. Multiple connection holes 211 are provided, spaced apart along the extension direction of the blade holder 21. This arrangement provides the blade holder 21 with a wider rotation range, allowing operators to adjust the connection hole 211 for rotatable connection with the second drive device 40 according to actual needs, thereby improving the versatility of the cutting device.

[0046] In this embodiment, there are five connecting holes 211 , and the five connecting holes 211 are arranged at intervals along the extending direction of the tool holder 21 .

[0047] It should be noted that the number of connection holes 211 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of connection holes 211 is two, three, four, six, seven, or more.

[0048] like Figure 1 As shown, the frame 10 also includes a base plate 12 and at least two mounting plates 13. The at least two mounting plates 13 are arranged on the base plate 12, and the at least two mounting plates 13 surround and form an installation space. The transmission structure 50 and the guide structure 60 are both arranged in the installation space. During the movement of the movable part 11, at least a portion of the mounting plate 13 is stopped by the movable part 11. In this way, the above arrangement, on the one hand, makes the structure of the frame 10 simpler and easier to manufacture, thereby reducing the processing cost of the frame 10 and the processing difficulty of the staff; on the other hand, the mounting plate 13 can serve as a limiter to limit the movement range of the movable part 11, ensuring that the cutting device has a high movement stability.

[0049] This embodiment further provides a tire processing device (not shown), comprising a conveying device, a control module, and a cutting device disposed on the conveying device. The conveying device is used to convey materials to be cut. The cutting device is disposed on the conveying device to cut the materials to be cut during the conveying process. The control module is connected to both the first drive device 30 and the second drive device 40 of the cutting device. The cutting device is the cutting device described above.

[0050] In this way, the control module of the tire processing equipment can control the working status of the first drive device 30 and the second drive device 40 according to the preset processing requirements, that is, control the speed and direction of the first drive device 30 to achieve the distance adjustment between the two tool assemblies 20, control the telescopic distance of the piston rod of the second drive device 40 to control the cutting timing of the tool assembly 20, and thereby enable the film on the tire processing equipment to be cut to the required width, so as to control the specific structure of the tire blank formed by winding the film, thereby improving the tire molding quality.

[0051] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0052] The cutting device is mounted on a conveying device for conveying material to be processed and includes a frame, a movable portion of the frame having a receiving space, a tool assembly movably mounted on the frame, at least a portion of the tool assembly being located within the receiving space, and configured to be driven by the movable portion to drive the tool assembly for movement. The tool assembly is rotatably mounted on a tool holder, the tool holder being rotatably mounted. A first drive is drivably connected to the movable portion to drive the tool assembly for movement by driving the movable portion to adjust the tool position on the material to be processed, and a second drive is drivably connected to the tool holder to drive the tool holder for rotation by driving the tool holder to drive the tool into contact with or away from the material to be processed. Thus, the cutting device mounted on the conveying device can actually cut the material to be processed during conveyance. Specifically, when the second drive drives the tool holder to rotate the tool until it contacts the material to be processed, the tool can passively cut the material to be processed during conveyance. Furthermore, when the first drive drives the movable portion to drive the tool assembly for movement, the cutting position of the tool can be adjusted to adjust the size of the material to be processed, thereby resolving the problem of the inability to adjust the size of the film on the tire processing equipment in the prior art. At the same time, the above arrangement enables the specific structure of the tire blank formed by winding the material to be processed to be adjusted accordingly, thereby improving the molding quality of the tire.
