Description

Technical Field

[0001] The present application belongs to the field of film cooling technology, and more specifically, relates to a cooling device for tire film. Background Art

[0002] Tires are circular, ground-engaging, rolling, elastic rubber products mounted on various vehicles and machinery. They often operate under complex and demanding conditions, subjecting them to various deformations, loads, forces, and high and low-temperature conditions. Therefore, they must exhibit high load-bearing, traction, and cushioning properties, as well as high wear and flex resistance, and low rolling resistance and heat buildup. Half of the world's rubber consumption is used in tire production, demonstrating the significant rubber consumption capacity of tires. The rubber sheet used in tire production is an essential component of tires, but existing tire sheet cooling devices suffer from inefficient and uneven cooling.

[0003] At present, Chinese patent publication No. CN214447841U discloses a film cooling device for tire production, comprising a support base, support legs are provided at the bottom corners of the support base, a cooling box is provided on the upper side of the support base, an opening and closing door is provided on the front of the cooling box, an observation window is provided above the front of the opening and closing door, and a control panel is provided on the front of the closing door and below the observation window, and an air collecting box is provided on the top of the cooling box, and a rotating placement cylinder is provided on the upper side of the support mounting frame, which can drive the rotating placement cylinder to rotate inside the cooling box through a set motor, and the set connecting pipe is a U-shaped structure, and the side walls of the rotating placement cylinder are evenly provided with ventilation holes, so that the cold air blown out by the air cooler can be blown to the rotating placement cylinder from the left, right and upper directions for cooling. In summary, the above-mentioned settings can make the cooling effect of the tire film better and more uniform when it is cooled.

[0004] During actual use of the above device, the film is placed in the rotating placement cylinder for cooling. If too much film is stacked, it takes more time to cool the film evenly, so it is difficult to cool the film quickly. After the film is cooled, it is necessary to open the box door to take out the film, and then continue to place the film to be cooled in the rotating placement cylinder for cooling. Continuous cooling operation cannot be performed, and the discharge and removal of materials are more troublesome, which affects the cooling efficiency. Summary of the Invention

[0005] The purpose of the utility model is to make up for the shortcomings of the existing technology and provide a cooling device for tire rubber sheets, which has the characteristics of quickly cooling the rubber sheets while moving the rubber sheets, effectively improving the processing efficiency of the rubber sheets, facilitating the automatic collection of the rubber sheets, and being easy to use.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a tire rubber sheet cooling device, comprising a cooling frame, wherein a first conveyor, a second conveyor, and a third conveyor are sequentially installed inside the cooling frame from top to bottom; two first air coolers distributed on the left and right are installed through the top surface of the cooling frame; a second air cooler and a third air cooler corresponding to the second conveyor and the third conveyor, respectively, are installed through the front surface of the cooling frame; an air outlet of the second air cooler is connected to a ventilation duct located above the second conveyor through a pipe;

[0009] In order to eject the airflow in the ventilation pipe, as a preferred embodiment of the tire rubber cooling device of the present invention, a plurality of nozzles are installed at the bottom of the outer side wall of the ventilation pipe.

[0010] In order to press and convey the film, as a preferred tire film cooling device of the present invention, the left and right walls of the cooling frame are both movably mounted with fixed frames through rotating shafts, and pressure rollers are installed inside the fixed frames, and the two pressure rollers are respectively in contact with the outer side walls of the first conveyor belt and the second conveyor belt.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0023] A tire rubber cooling device body provided in an embodiment of the present application is now described.

[0024] like Figures 1 to 3 As shown, a tire rubber sheet cooling device includes a cooling frame 1. A first conveyor 2, a second conveyor 3, and a third conveyor 4 are installed in sequence from top to bottom inside the cooling frame 1. Two first cooling air fans 201 are installed on the top surface of the cooling frame 1, which are distributed on the left and right. A second cooling air fan 301 and a third cooling air fan 401 corresponding to the second conveyor 3 and the third conveyor 4, respectively, are installed on the front surface of the cooling frame 1. The air outlet of the second cooling air fan 301 is connected to a ventilation pipe 302 located above the second conveyor 3 through a pipe.

[0025] A first conveying frame 5 is mounted on the left side wall of the first conveyor 2. A plurality of first conveying rollers 501 are mounted inside the first conveying frame 5. A bidirectional screw rod 502 is rotatably connected to the rear end surface of the first conveying frame 5. Two sliders 503 are movably mounted on the outer side wall of the bidirectional screw rod 502. Limit rollers 504 are movably mounted on the upper end surfaces of the two sliders 503 via rotating shafts.

[0026] A second conveying frame 7 is movably mounted on the right side wall of the third conveyor 4 via a rotating shaft, a plurality of second conveying rollers 701 are mounted inside the second conveying frame 7, and an electric push rod 702 is movably mounted between the bottom end surface of the second conveying frame 7 and the right side wall of the second conveying frame 7 via a rotating shaft.

[0027] In this embodiment: when in use, by rotating the bidirectional screw rod 502, the two sliders 503 and the two limiting rollers 504 can be driven to move, so that the distance between the two limiting rollers 504 can be adjusted, and the two limiting rollers 504 can limit the film, and then the pressure roller 601 presses one end of the film, and by starting the first conveyor 2, the second conveyor 3, the third conveyor 4, the two first cooling air machines 201, the second cooling air machine 301 and the third cooling air machine 401, the pressure roller 601 on the left cooperates with the first conveyor 2 to press and convey the film. When the film passes through the two second conveyors 2, the second conveyor 3 and the third conveyor 4, the pressure roller 601 on the left cooperates with the first conveyor 2 to press and convey the film. When the first cooling air machine 201 is used, the cold air flow blown by the two first cooling air machines 201 can initially cool the film. When the film moves to the second conveyor 3, the pressing roller 601 on the right side presses the film, and the second conveyor 3 cooperates to convey the film further. At this time, the second cooling air machine 301 flows the cold air into the ventilation pipe 302 through the pipe, so that multiple nozzles blow out the cold air to cool the other side of the film. Then, when the film moves to the third conveyor 4, the third cooling air machine 401 can further cool the film, thereby achieving the effect of quickly cooling the film.

[0028] When the film moves into the second conveying frame 7, by starting the electric push rod 702, the second conveying frame 7 is pushed to swing back and forth in coordination with the rotation speed of the conveyor belt of the third conveyor 4, so that the film is stacked in the collection box 8, which is convenient for automatic collection of the film and easy to use.

[0029] As a technical optimization solution of the present invention, a plurality of nozzles are installed at the bottom of the outer side wall of the ventilation pipe 302 .

[0030] In this embodiment, a plurality of nozzles are provided to spray out the cold air flow in the ventilation pipe 302 .

[0031] As a technical optimization solution of the present invention, the left and right walls of the cooling frame 1 are both movably mounted with a fixed frame 6 through a rotating shaft, and a pressure roller 601 is installed inside the fixed frame 6. The two pressure rollers 601 are respectively in contact with the outer walls of the conveyor belt of the first conveyor 2 and the conveyor belt of the second conveyor 3.

[0032] In this embodiment, by lifting the fixing frame 6 on the corresponding conveyor, the film is placed on the conveyor belt of the first conveyor 2. When the fixing frame 6 is placed on the conveyor belt, the pressure roller 601 cooperates with the conveyor belt to press and convey the film.

[0033] As a technical optimization solution of the present invention, the front end of the bidirectional screw rod 502 passes through the front end face of the first conveying frame 5 and is installed with a handwheel. The inner bottom end face of the first conveying frame 5 is provided with a sliding groove 505 that is slidably connected to the two sliders 503.

[0034] In this embodiment, a hand wheel is provided to facilitate the rotation of the bidirectional screw rod 502, and a slide groove 505 is provided so that when the slider 503 moves, the slide groove 505 can limit the moving direction of the slider 503, thereby enabling the slider 503 to move stably.

[0035] As a technical optimization solution of the present invention, a collection box 8 is installed at the bottom of the right side wall of the cooling frame 1.

[0036] In this embodiment, a collection box 8 is provided to facilitate the collection of the cooled film.

[0037] As a technical optimization solution of the present invention, the conveyor belts of the first conveyor 2, the second conveyor 3 and the third conveyor 4 are in a mesh shape.

[0038] In this embodiment, the conveyor belts of the first conveyor 2, the second conveyor 3 and the third conveyor 4 are arranged in a mesh shape to facilitate air flow.

[0039] Working principle: First, when using the device, connect the device to an external power supply, and then adjust the distance between the two limiting rollers 504 according to the width of the film. The specific operation is to rotate the bidirectional screw rod 502 by the hand wheel to drive the two sliders 503 and the two limiting rollers 504 to move, so as to adjust the distance between the two limiting rollers 504. Then, place one end of the film to be cooled on the multiple first conveying rollers 501 in the first conveying frame 5. The two limiting rollers 504 can limit the film. Then, move it to the conveyor belt of the first conveyor 2 through the two limiting rollers 504. At this time, by lifting the fixed frame 6 on the left, the pressure roller 601 presses the film. Then start the first conveyor 2, the second conveyor 3, the third conveyor 4, and the two first cooling air fans 2 01, the second cooling air machine 301 and the third cooling air machine 401, so that the pressure roller 601 on the left cooperates with the first conveyor 2 to press and convey the film, thereby increasing the stability of the film movement. When the film passes through the two first cooling air machines 201, the cold air flow blown out by the two first cooling air machines 201 can initially cool the film. When the film moves to the second conveyor 3, the pressure roller 601 on the right presses the film and cooperates with the second conveyor 3 to continue conveying the film. At this time, the second cooling air machine 301 flows the cold air into the ventilation pipe 302 through the pipe, so that multiple nozzles blow out the cold air to cool the other side of the film. Then, when the film moves to the third conveyor 4, the third cooling air machine 401 can further cool the film, thereby achieving the effect of quickly cooling the film.

[0040] When the film moves into the second conveying frame 7, the electric push rod 702 is activated to push the second conveying frame 7 to swing back and forth in coordination with the rotation speed of the conveyor belt of the third conveyor 4, so that the film is stacked in the collection box 8 for collection.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
