Description

Technical Field

[0001] The present application relates to the field of tire rubber radiation pre-vulcanization technology, and in particular to a radiation vulcanization device for rubber tire production. Background Art

[0002] With the rapid development of the automotive industry, the demand for tire quality is becoming increasingly stringent. Vulcanization, a crucial step in tire manufacturing, aims to optimize the physical and mechanical properties of every tire component. Therefore, the uniformity of vulcanization significantly impacts tire performance. Because tires are thick rubber products and poor conductors of heat, by the time the interior of the tire reaches full vulcanization, the exterior surface is already over-vulcanized. This uneven vulcanization significantly impacts tire quality.

[0003] In the prior art, tire manufacturing rubber sheets primarily consist of a machine body, which includes an irradiation chamber formed within it for the rubber sheets to circulate. The irradiation end of the irradiation main unit is mounted on the top of the irradiation chamber, and a radiation shielding mechanism is installed on the inner wall of the irradiation chamber. The irradiation chamber has an inlet and outlet at each end, for feeding the irradiated rubber sheets. A lower beam drive roller assembly (consisting of a tensioning mechanism, support rollers, floating pressure rollers, and a drive roller assembly) is rotatably connected within the irradiation chamber. The rubber sheets are fed through the drive roller assembly through the inlet, passed through the irradiation main unit for irradiation pre-vulcanization, and then discharged through the outlet.

[0004] However, when the rubber sheet is being transported through the irradiation chamber, if the transmission tension of the transmission roller group under the beam is too large, the rubber sheet may be easily deformed due to stretching. Manual monitoring of the deformation state of the rubber sheet is inefficient, and there is room for improvement. Utility Model Content

[0005] In order to improve the efficiency of continuous deformation detection of rubber sheets, the present application provides a radiation vulcanization device for rubber tire manufacturing.

[0006] The present application provides a radiation vulcanization device for manufacturing rubber tires, which adopts the following technical solutions:

[0007] A radiation vulcanization device for manufacturing rubber tires, comprising a body, with transmission roller groups provided at both ends of the body, the transmission roller groups including induction rollers; and:

[0008] An infrared emitting end, fixedly mounted on the side wall of the machine body, for emitting infrared rays;

[0009] An infrared receiving end is fixedly mounted on the end surface of the sensing roller close to the infrared emitting end, and is used to receive the infrared rays and emit a high-level signal;

[0010] A first single-chip microcomputer, whose signal input terminal is signal-connected to the signal output terminal of the infrared receiving terminal, is used to count the number of occurrences of the high-level signal and output a trigger signal when the number of occurrences of the high-level signal reaches a set value or an integer multiple of the set value;

[0011] An image collector is fixedly mounted on the machine body, located on one side of the discharge port of the machine body, mounted on the surface of the rubber sheet, with a signal input terminal connected to a signal output terminal of the first single-chip microcomputer, for receiving the trigger signal and outputting image data;

[0012] an image data processor, data-connected to the data output terminal of the image collector, configured to receive the image data and output a first alarm signal when the image data is abnormal;

[0013] an audible and visual alarm, fixedly mounted on the machine body, with a signal input terminal connected to a signal output terminal of the image data processor, for receiving the first alarm signal and issuing a warning signal;

[0014] Mounting grooves for mounting the infrared transmitting end and the infrared receiving end are respectively provided on the end face of the sensing roller and the side wall of the body. A transparent cover is hinged at the notch of the mounting groove, and a quick switch structure is provided between the transparent cover and the inner wall of the mounting groove.

[0015] By adopting the above technical solution, during the actual production process, the transmission roller assembly pulls the rubber sheet through the interior of the machine body, and the irradiation main unit performs irradiation pre-vulcanization treatment on the rubber sheet passing through the irradiation chamber. During the flow of the rubber sheet, the induction roller in the transmission roller assembly rotates at a constant speed. Since each rotation of the induction roller corresponds to a fixed length of the conveyed rubber sheet, the infrared transmitter and the infrared receiver are aligned once for each rotation of the induction roller. The infrared receiver receives infrared rays and outputs a high-level signal. The first single-chip microcomputer calculates the number of occurrences of the high-level signal, thereby achieving the technical effect of automatically detecting the conveyed length of the rubber sheet. At the same time, the first single-chip microcomputer automatically controls the image acquisition device to collect image data when the number of occurrences of the high-level signal reaches a set value or an integer multiple of the set value, thereby achieving the technical effect of continuously collecting image data of the rubber sheet. After comparison by the image data processor, the shape of the rubber sheet can be analyzed. When the rubber sheet is deformed, the audible and visual alarm is automatically controlled to emit a warning sound and flash, notifying the on-site operator of the rubber sheet deformation so that the operator can take relevant debugging measures. For example, if the image acquisition device captures an image of 40 cm in length, and the rubber sheet conveyed during each rotation of the induction roller is 4 cm long, then when the high-level signal occurs 10 times or an integer multiple of 10, the image acquisition device is triggered to take a photo of the rubber sheet. This allows for continuous detection of rubber sheet deformation, effectively saving manpower and improving the efficiency of rubber sheet deformation monitoring. Furthermore, the transparent cover at the notch of the mounting slot ensures infrared penetration while providing excellent protection for the infrared transmitter and receiver. A quick-release mechanism allows operators to quickly open the transparent cover for maintenance and inspection of the infrared receiver and transmitter.

[0016] Preferably, the outer rings of the slots of the two mounting slots are respectively fixedly connected with connecting parts, and the two transparent cover plates are respectively hinged on the two connecting parts;

[0017] The quick switch structure includes a first connecting member and a second connecting member, wherein the first connecting member is slidably connected to the connecting portion, and the second connecting member is fixedly connected to a side of the transparent cover plate close to the mounting groove;

[0018] The connecting portion is provided with a through hole for the first connecting member to extend into, a metal spring is fixedly connected to the inner wall of the connecting portion, and one end of the first connecting member passing through the through hole is fixedly connected to a push plate;

[0019] A protrusion is integrally formed on one side of the push plate close to the connecting portion, and a bayonet adapted to the protrusion is provided on the second connecting member. The first connecting member and the second connecting member are tightly pressed between the spring sheet and the connecting portion, and the protrusion is snap-fitted into the bayonet.

[0020] By adopting the above technical solution, when it is necessary to open the cover to inspect the infrared transmitting end or the infrared receiving end, the relevant personnel can push the first connecting member and at the same time flip the transparent cover upward to pull the second connecting member out from between the first push plate and the connecting part, thereby achieving the technical effect of quickly separating the cover; when the maintenance and inspection is completed, the relevant personnel can push the first connecting member to facilitate the insertion of the second connecting member, and through the protrusion on the push plate and the bayonet on the second connecting member, the first connecting member and the second connecting member can be engaged and connected, thereby preventing the cover from detaching from the connecting part in a sealed state.

[0021] Preferably, one end of the first connecting member away from the push plate is fixedly connected to a pressing plate, and the width of the pressing plate is greater than the width of the through hole.

[0022] By adopting the above technical solution, the pressing plate can increase the contact area between the fingers of the relevant personnel and the first connecting member, thereby improving the convenience of pressing and pushing the first connecting member and reducing the occurrence of the first connecting member falling off.

[0023] Preferably, the signal output terminal of the infrared receiving terminal is connected to a second single chip microcomputer, and the second single chip microcomputer receives the low level signal and outputs a second alarm signal when the duration of the low level signal is greater than a set time value;

[0024] An LED indicator light is fixedly mounted on the side wall of the machine body. The signal input end of the LED indicator light is connected to the signal output end of the second single chip microcomputer. The LED indicator light receives the second alarm signal and emits light.

[0025] By adopting the above technical solution, when the infrared transmitting end and the infrared receiving end are misaligned, the infrared receiving end outputs a low-level signal. When the infrared receiving end or the infrared transmitting end is abnormal (or the transparent cover is dirty), the infrared receiving end cannot sense infrared rays and continues to output a low-level signal. The second single-chip microcomputer calculates the duration of the low-level signal, thereby achieving the technical effect of self-checking the working status of the infrared transmitting end and the infrared receiving end. In addition, the second single-chip microcomputer can automatically control the LED indicator to light up when the low-level signal lasts for too long, thereby promptly reminding relevant personnel on site to maintain and repair the infrared transmitting end and the infrared receiving end.

[0026] In summary, the radiation vulcanization device for manufacturing rubber tires in the present application has at least one of the following beneficial technical effects:

[0027] 1. During the actual production process, the transmission roller group pulls the rubber sheet through the inside of the machine body, and the irradiation host performs irradiation pre-vulcanization treatment on the rubber sheet passing through the irradiation cavity. During the flow of the rubber sheet, the induction roller in the transmission roller group rotates at a constant speed. Since the length of the conveyed rubber sheet corresponding to each rotation of the induction roller is a fixed value, the infrared transmitting end and the infrared receiving end are opposite to each other once when the induction roller rotates one circle. The infrared receiving end receives the infrared rays and outputs a high-level signal. The first single-chip microcomputer calculates the number of occurrences of the high-level signal, thereby realizing the technical effect of automatically detecting the conveying length of the rubber sheet. At the same time, the first single-chip microcomputer can automatically control the image collector to collect image data when the number of occurrences of the high-level signal is a set value or an integer multiple of the set value, thereby realizing the technical effect of continuously collecting image data of the rubber sheet. After comparison by the image data processor, the shape of the rubber sheet can be analyzed, and the sound and light alarm can be automatically controlled to emit a warning sound and flash when the rubber sheet is deformed, thereby prompting the on-site operator that the rubber sheet is deformed so that the operator can take relevant debugging measures. Thus, the technical effect of continuously detecting whether the rubber sheet is deformed can be realized, which can effectively save manpower investment and improve the efficiency of monitoring the deformation of the rubber sheet.

[0028] 2. The transparent cover at the notch of the installation slot can ensure the penetration effect of infrared rays while providing good protection for the infrared transmitter and infrared receiver. The quick switch structure allows operators to quickly open the transparent cover to maintain and inspect the infrared receiver and infrared transmitter. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] Example

[0036] The embodiment of the present application discloses a radiation vulcanization device for manufacturing rubber tires. Figures 1-4 , including a body 1, with transmission roller groups 2 provided at both ends of the body 1, and the transmission roller group 2 including an induction roller 21, wherein the induction roller 21 is located on the feed port side of the body 1.

[0037] And: an infrared transmitting end 3, fixedly mounted on the side wall of the machine body 1, for emitting infrared rays; an infrared receiving end 4, fixedly mounted on the end surface of the induction roller 21 close to the infrared transmitting end 3, for receiving infrared rays and sending out a high-level signal; a first single-chip microcomputer, whose signal input end is signal-connected to the signal output end of the infrared receiving end 4, for counting the number of occurrences of the high-level signal and outputting a trigger signal when the number of occurrences of the high-level signal is a set value or an integer multiple of the set value; an image collector 5, fixedly mounted on the machine body 1, located on one side of the discharge port of the machine body 1, mounted on the surface of the rubber sheet, whose signal input end is signal-connected to the signal output end of the first single-chip microcomputer, for receiving a trigger signal and outputting image data; an image data processor, data-connected to the data output end of the image collector 5, for receiving image data and outputting a first alarm signal when the image data is abnormal; an audible and visual alarm 6, fixedly mounted on the machine body 1, whose signal input end is signal-connected to the signal output end of the image data processor, for receiving a first alarm signal and sending out a warning signal.

[0038] Mounting grooves 12 for mounting the infrared transmitting end 3 and the infrared receiving end 4 are respectively provided on the end face of the sensing roller 21 and the side wall of the body 1. A transparent cover 13 is hinged at the notch of the mounting groove 12, and a quick switch structure 14 is provided between the transparent cover 13 and the inner wall of the mounting groove 12.

[0039] During the actual production process, the transmission roller assembly 2 pulls the rubber sheet through the interior of the machine body 1, and the irradiation host performs irradiation pre-vulcanization on the rubber sheet passing through the irradiation chamber 11. As the rubber sheet flows, the induction roller 21 in the transmission roller assembly 2 rotates at a constant speed. Since each rotation of the induction roller 21 corresponds to a fixed length of the conveyed rubber sheet, the infrared emitting terminal 3 and the infrared receiving terminal 4 are aligned once for each rotation of the induction roller 21. The infrared receiving terminal 4 receives infrared rays and outputs a high-level signal. The first single-chip microcomputer calculates the number of occurrences of the high-level signal, thereby automatically detecting the conveyed length of the rubber sheet. At the same time, the first single-chip microcomputer automatically controls the image acquisition device 5 to collect image data when the number of occurrences of the high-level signal reaches a set value or an integer multiple of the set value, thereby continuously collecting image data of the rubber sheet. After comparison by the image data processor, the shape of the rubber sheet can be analyzed. When the rubber sheet is deformed, the sound and light alarm 6 is automatically controlled to emit a warning sound and flash, notifying the on-site operator of the rubber sheet deformation so that the operator can take relevant debugging measures.

[0040] For example, if the length of the image collected by the image collector 5 is 40 cm, and the conveying length of the rubber sheet is 4 cm per rotation of the induction roller 21, then when the high-level signal appears 10 times or an integer multiple of 10, the image collector 5 is triggered to take a picture of the rubber sheet, which can achieve the technical effect of continuously detecting whether the rubber sheet is deformed, and can effectively save manpower investment.

[0041] In addition, the transparent cover at the slot of the installation slot 12 can ensure the penetration effect of infrared rays while providing good protection for the infrared transmitting end 3 and the infrared receiving end 4; the quick switch structure can facilitate the operator to quickly open the transparent cover to maintain and inspect the infrared receiving end 4 and the infrared transmitting end 3.

[0042] Reference Figure 2 and Figure 3 The outer rings of the slots of the two mounting grooves 12 are respectively fixedly connected with connecting parts 15, and the two transparent cover plates 13 are respectively hinged on the two connecting parts 15; the quick switch structure includes a first connecting member 141 and a second connecting member 142, the first connecting member 141 is slidably connected to the connecting part 15, and the second connecting member 142 is fixedly connected to the side of the transparent cover plate 13 close to the mounting groove 12; a through hole 151 is opened on the connecting part 15 for the first connecting member 141 to extend into, a metal spring is fixedly connected to the inner wall of the connecting part 15, and one end of the first connecting member 141 passing through the through hole 151 is fixedly connected to the push plate 143.

[0043] A protrusion 144 is integrally formed on one side of the push plate 143 near the connecting portion, and a bayonet 145 adapted to the protrusion 144 is opened on the second connecting member 142. The first connecting member 141 and the second connecting member 142 are tightly pressed between the spring sheet and the connecting portion, and the protrusion 144 is engaged and fixed in the bayonet 145.

[0044] When it is necessary to open the cover to inspect the infrared emitting terminal 3 or the infrared receiving terminal 4, the relevant personnel can push the first connecting member 141 and at the same time flip the transparent cover upwards so that the second connecting member 142 is pulled out from between the first push plate 143 and the connecting part 15, thereby achieving the technical effect of quickly separating the cover; when the maintenance and inspection is completed, the relevant personnel can push the first connecting member 141 to facilitate the insertion of the second connecting member 142, and through the protrusion 144 on the push plate 143 and the bayonet 145 on the second connecting member 142, the first connecting member 141 and the second connecting member 142 can be engaged and connected, thereby preventing the cover from detaching from the connecting part 15 in a sealed state.

[0045] Reference Figure 3 One end of the first connecting member 141 away from the push plate 143 is fixedly connected to the pressing plate, and the width of the pressing plate is greater than the width of the through hole 151.

[0046] The pressing plate can increase the contact area between the fingers of the relevant personnel and the first connecting member 141, thereby improving the convenience of pressing and pushing the first connecting member 141 and reducing the occurrence of the first connecting member 141 falling off.

[0047] Reference Figure 2 and Figure 4 The signal output terminal of the infrared receiving terminal 4 is connected to the second single chip microcomputer, which receives the low level signal and outputs the second alarm signal when the duration of the low level signal is greater than the set time value.

[0048] An LED indicator light 16 is fixedly mounted on the side wall of the machine body 1 . The signal input terminal of the LED indicator light 16 is connected to the signal output terminal of the second single chip microcomputer. The LED indicator light 16 receives the second alarm signal and emits light.

[0049] When the infrared transmitting end 3 and the infrared receiving end 4 are misaligned, the infrared receiving end 4 outputs a low-level signal. When the infrared receiving end 4 or the infrared transmitting end 3 is abnormal (or the transparent cover 13 is dirty), the infrared receiving end 4 cannot sense infrared rays and continues to output a low-level signal. The second single-chip microcomputer calculates the duration of the low-level signal, thereby achieving a technical effect of self-checking the working status of the infrared transmitting end 3 and the infrared receiving end 4. The second single-chip microcomputer can automatically control the LED indicator 16 to light up when the low-level signal lasts too long, thereby promptly reminding relevant on-site personnel to maintain and repair the infrared transmitting end 3 and the infrared receiving end 4.

During the flow of the rubber sheet, the sensing roller 21 in the transmission roller group 2 rotates at a constant speed. Since the length of the conveyed rubber sheet corresponding to each rotation of the sensing roller 21 is a fixed value, the infrared transmitting end 3 and the infrared receiving end 4 are opposite to each other once when the sensing roller 21 rotates one circle. The infrared receiving end 4 receives the infrared rays and outputs a high-level signal. The first single-chip microcomputer calculates the number of occurrences of the high-level signal, thereby achieving the technical effect of automatically detecting the conveying length of the rubber sheet. At the same time, the first single-chip microcomputer can automatically control the image collector 5 to collect image data when the number of occurrences of the high-level signal is a set value or an integer multiple of the set value, thereby achieving the technical effect of continuously collecting image data of the rubber sheet. After comparison by the image data processor, the shape of the rubber sheet can be analyzed, and when the rubber sheet is deformed, the sound and light alarm 6 can be automatically controlled to emit a warning sound and flash, prompting the on-site operator that the rubber sheet is deformed so that the operator can take relevant debugging measures. The technical effect of continuously detecting whether the rubber sheet is deformed can be achieved, which can effectively save manpower investment and improve the efficiency of monitoring the deformation of the rubber sheet.
