Description

Technical Field

[0001] This invention belongs to the field of tire semi-finished product manufacturing technology, specifically relating to an infrared heating cutting device, method, and application. Background Technology

[0002] Currently, equipment used for cutting semi-finished tires needs to cut tire components of various sizes. The cutting blades used in this process require heating to prevent them from sticking to subsequent rubber products and causing blockages, thus forcing production to stop. Currently, heating the blades primarily involves installing electric heating rods, which presents several problems:

[0003] A semi-circular groove needs to be machined into the cutter and one of the clamping plates to fix the heating rod. This machining method is unconventional and inconvenient.

[0004] Because of the semi-circular groove on the cutter, the angle of the blade is limited by the structure and cannot be made smaller (the smaller the angle, the sharper the cutter).

[0005] Since the electric heating rod needs to be powered and rotates along with the cutter, a through-hole slip ring is required to power the heating rod. Furthermore, the friction between the slip ring and the brush generates heat and is prone to wear, making the structure more complex.

[0006] The installation distance between the heating rod and the cutting edge cannot be too large, otherwise when the thickness of the rubber material is large, the clamp of the electric heating rod will come into contact with the rubber material and form pressure, eventually causing the cutter to jam and block the rubber, thus forcing the production to stop.

[0007] In addition, the electric heating rod can only heat the inside. Tests have shown that it has the disadvantages of slow heating and uneven surface heating after heat transfer. Summary of the Invention

[0008] The purpose of this invention is to solve the problems existing in the prior art and provide an infrared heating cutting device, method and application. It uses infrared heat conduction to directly heat the cutting edge of the cutter, which has a large heating area and uniform temperature, and avoids angle limitations, thereby improving the processing conditions of the cutter, simplifying the overall structure and expanding the application range of the cutter.

[0009] This invention is achieved through the following technical solution:

[0010] A first aspect of the present invention provides an infrared heating cutting device, including a cutting device and an infrared heating device disposed above the cutting device.

[0011] A further improvement of the present invention is that:

[0012] The infrared heating device includes a mounting bracket, in which multiple infrared heaters are fixed sequentially, and the multiple infrared heaters are located above the cutting device.

[0013] A further improvement of the present invention is that:

[0014] The infrared heating cutting device also includes a controller, which is electrically connected to multiple infrared heaters and is used to control the infrared heaters to start or stop heating.

[0015] A further improvement of the present invention is that:

[0016] The cutting device includes two fixed supports arranged opposite to each other, and a rotating shaft is provided between the two fixed supports. A cutting blade is fixed on the rotating shaft by a cutting blade mounting seat. The cutting blade rotates as the rotating shaft rotates.

[0017] Multiple infrared heaters are located directly above the cutter.

[0018] A further improvement of the present invention is that:

[0019] The cutter is equipped with at least one temperature sensor, which is connected to the controller. The temperature sensor is used to detect the temperature of the cutter in real time and transmit the data to the controller.

[0020] A further improvement of the present invention is that:

[0021] The blade angle of the cutter is 8-15°, and the thickness of the blade body is 10mm.

[0022] A further improvement of the present invention is that:

[0023] The cutter mounting base includes a rotating shaft connecting part and a cutter fixing part;

[0024] The cutter fixing part is vertically fixed on one of the long sides of the rotating shaft connecting part. The rotating shaft connecting part has a through hole along the length direction. The rotating shaft passes through the through hole so that the rotating shaft connecting part is sleeved on the rotating shaft.

[0025] The cutter is fixed to the cutter fixing part.

[0026] A further improvement of the present invention is that:

[0027] The cutter has a bolt hole at its bottom, and bolt through holes are provided on the rotating shaft connection and the rotating shaft. The bolt through holes and bolt holes are positioned correspondingly. The adjusting bolt passes through the bolt through holes and bolt holes in sequence to adjust the height of the cutter.

[0028] A second aspect of the present invention provides an infrared heating cutting method, wherein the infrared heating cutting device described above is used to cut tire parts, and the infrared heating device heats the cutting blade during the cutting process.

[0029] A third aspect of the invention is the application of the infrared heating cutting device described above in the production of tire semi-finished products.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] This invention features a heating device consisting of multiple infrared heaters connected in series above the cutting device. Since infrared radiation is a long-wavelength electromagnetic radiation, it can penetrate the air and generate a thermal effect on the surface of an object. This principle is used to heat the cutting edge of the cutter, which ensures uniform temperature of the cutting edge and a large heating area, while avoiding angle limitations. This improves the processing conditions of the cutter, simplifies the overall structure, and expands the application range and cutting effect of the cutter.

[0032] Because the infrared heater used in this invention is arc-shaped, it has a good heat concentration effect and little outward radiation, so the accuracy requirements for the stop position of the cutter are not high. The blade angle of the cutter in this invention is 8-15°, which improves the sharpness of the cutter and thus extends its service life and reduces the amount of equipment maintenance. In addition, the thickness of the cutter body is reduced from 20mm to 10mm, which improves the sharpness of the cutter while reducing the amount of special cutter steel used and reducing manufacturing costs.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings:

[0038] like Figure 1As shown, an embodiment of the present invention provides an infrared heating cutting device, including a cutting device and an infrared heating device disposed above the cutting device.

[0039] The present invention provides an infrared heating device above the cutting device. Since infrared radiation is a long-wavelength electromagnetic radiation, it can penetrate the air and generate a thermal effect on the surface of an object. This principle is used to heat the cutting edge of the cutting device, which ensures uniform temperature of the cutting edge and a large heating area, and avoids angle limitations. This improves the processing conditions of the cutting device, simplifies the overall structure, and expands the application range and cutting effect of the cutting device.

[0040] As a preferred embodiment of the present invention, such as Figure 2 As shown, the infrared heating device includes a mounting bracket 12, in which multiple infrared heaters 2 are fixed in sequence. The multiple infrared heaters 2 are located directly above the cutter. Infrared rays are used to directly heat the cutting edge of the cutter 1, which ensures uniform temperature of the cutting edge and a large heating area, and avoids angle limitations. This improves the processing conditions of the cutter, simplifies the overall structure, expands the application range of the cutter, and improves the cutting effect.

[0041] Preferably, the heating surface of the infrared heater 2 is arc-shaped, which makes the heat concentration effect good and the outward radiation small during infrared heating, and the positional accuracy requirement for the stop of the cutter is not high.

[0042] In a preferred embodiment of the present invention, the infrared heating cutting device further includes a controller (not shown in the figure), which is electrically connected to a plurality of infrared heaters 2 and is used to control the infrared heaters 2 to start heating or stop heating.

[0043] In a preferred embodiment of the present invention, the cutting device includes two fixed supports 9 arranged opposite to each other, and a rotating shaft 10 is arranged between the two fixed supports 9. A cutting blade 1 is fixed on the rotating shaft 10 by a cutting blade mounting seat 4, and the cutting blade 1 can rotate as the rotating shaft 10 rotates. Preferably, a plurality of infrared heaters 2 are located directly above the cutting blade 1.

[0044] In a preferred embodiment of the present invention, at least one temperature sensor (not shown in the figure) is provided on the cutter 1, and the temperature sensor is connected to the controller. The temperature sensor is used to detect the temperature of the cutter 1 in real time and transmit it to the controller. The controller determines whether the cutter needs to be heated further based on the detected cutter temperature. If heating is required, the controller will control the infrared heater 2 to turn on to heat the cutter; otherwise, it will control the infrared heater to turn off.

[0045] In a preferred embodiment of the present invention, the blade angle of the cutter 1 is 8-15° and the thickness of the blade body is 10mm. In the prior art, due to structural limitations, the blade angle of the cutter is set to 25° and the blade thickness is 20mm. Compared with the prior art, the present invention improves the sharpness of the cutter while reducing the amount of steel used in the cutter and reducing manufacturing costs.

[0046] In a preferred embodiment of the present invention, the two ends of the rotating shaft 10 are respectively fixed on two fixed supports 9 by support bearings 3, and one end of the rotating shaft 10 extends out of the fixed support 9 and is connected to the transmission shaft of the motor 8. The motor 8 is fixed on the fixed support 9, and drives the rotating shaft 10 to rotate through the transmission shaft of the motor 8, thereby driving the cutter 1 to rotate.

[0047] As a preferred embodiment of the present invention, such as Figure 3 As shown, the cutter mounting base 4 is an integrally formed structure, including a rotating shaft connecting part 401 and a cutter fixing part 402. The cutter fixing part 402 is vertically fixed on one of the long sides of the rotating shaft connecting part 401. The rotating shaft connecting part 401 has a through hole 403 along its length. The rotating shaft 10 passes through the through hole 403, so that the rotating shaft connecting part 401 is sleeved on the rotating shaft 10. The cutter 1 is fixed to the cutter fixing part 402 by fixing bolts 7. When the rotating shaft 10 rotates under the drive of the motor 8, it drives the cutter mounting base 4 to rotate, thereby driving the cutter 1 to rotate. Multiple fixing bolts 7 are evenly distributed.

[0048] Preferably, the cutter 1 has a bolt hole at its bottom, and bolt through holes are provided on the rotating shaft connection 401 and the rotating shaft 10, with the bolt through holes and bolt holes corresponding to each other. The adjusting bolt 5 passes through the bolt through holes and bolt holes in sequence to adjust the height of the cutter. More preferably, multiple bolt holes and bolt through holes are provided.

[0049] Preferably, the cutter mounting base 4 is provided with a position indicator 6 for detecting the position of the cutter 1. More preferably, at least two position indicators 6 are provided for detecting different positions of the cutter to prevent the cutter from tilting.

[0050] In a preferred embodiment of the present invention, a reinforcing rib 11 is fixed between the bottoms of the two fixed supports 9 to improve the stability of the entire device, and the height of the reinforcing rib 11 does not affect the rotation of the cutter.

[0051] This invention also provides an infrared heating cutting method, which uses the aforementioned infrared heating cutting device to perform the cutting operation, specifically as follows:

[0052] Start motor 8, the drive shaft of motor 8 drives the rotating shaft 10 to rotate, which in turn drives the cutter 1 to rotate to cut the tire parts. At the same time, the controller controls the infrared heater 2 to turn on to heat the cutter, so as to prevent the cold cutter from sticking to subsequent rubber products and causing glue blockage.

[0053] During the cutting process, the temperature of the cutter is detected in real time by a temperature sensor and transmitted to the controller. The controller controls the start and stop of the infrared heater based on the detected cutter temperature.

[0054] This invention features a heating device consisting of multiple infrared heaters connected in series above the cutting device. Since infrared radiation is a long-wavelength electromagnetic radiation, it can penetrate the air and generate a thermal effect on the surface of an object. This principle is used to heat the cutting edge of the cutter, which ensures uniform temperature of the cutting edge and a large heating area, while avoiding angle limitations. This improves the processing conditions of the cutter, simplifies the overall structure, and expands the application range and cutting effect of the cutter.

[0055] Because the infrared heater used in this invention is arc-shaped, it has a good heat concentration effect and little outward radiation, so the accuracy requirements for the stop position of the cutter are not high. The blade angle of the cutter in this invention is 8-15°, which improves the sharpness of the cutter and thus extends its service life and reduces the amount of equipment maintenance. In addition, the thickness of the cutter body is reduced from 20mm to 10mm, which improves the sharpness of the cutter while reducing the amount of special cutter steel used and reducing manufacturing costs.
