Description

Technical Field

[0001] The utility model relates to the technical field of transmission and cooling of rubber products, in particular to a rubber block feeding mechanism. Background Art

[0002] In tire manufacturers, the production of rubber primary products is an important process before tire production. In this process, the rubber raw materials are first heated to a certain temperature to melt and become soft, so as to facilitate subsequent calendering or extrusion operations. In this process, the rubber will absorb a lot of heat.

[0003] Therefore, after the rubber is calendered or extruded by the extrusion equipment, its temperature is still relatively high. If it is directly processed or stored, it may cause deformation, aging or other quality problems of the rubber. In addition, when the rubber at a relatively high temperature is transmitted, the rubber is easy to adhere to the transmission equipment, which is not conducive to transportation during the transportation process. There are also problems such as poor heat dissipation effect of the existing traditional belt transmission equipment. Utility Model Content

[0023] Example 1

[0024] Please refer to Figure 1-Figure 4 shown.

[0025] The utility model provides a rubber block feeding mechanism, such as Figure 1 , Figure 2As shown, the utility model provides a rubber block feeding mechanism, including a frame 1 and a plurality of material transfer hoppers 4, the plurality of material transfer hoppers 4 are arranged on the frame 1 in a surrounding manner, a driving mechanism for driving the plurality of material transfer hoppers 4 to reciprocate on the frame 1 is provided in the frame 1, a plurality of exhaust pipes 10 are arranged in an array in the frame 1, a main conveying pipe 11 connected to the plurality of exhaust pipes 10 is provided in the frame 1, and an air supply device 2 connected to the main conveying pipe 11 is provided on the frame 1. The rubber block feeding mechanism provided in the present technical solution is to cut the rubber strips in sheet or block shape after being calendered or extruded by the extrusion equipment into blocks by a cutter, and then transmit them through the surrounding transfer hopper 4 installed on the frame 1. During the transmission process, the transfer hopper 4 transmits the block-shaped rubber blocks separately, which can accelerate the heat dissipation of the rubber blocks, avoid the rubber blocks from being connected as a whole, reduce the volume of the rubber strips, increase the relative area of ​​heat dissipation of the rubber blocks, and accelerate the heat dissipation effect; and the array of exhaust ducts 10 provided in the frame 1 can guide the cold air input by the air supply equipment 2 to the transfer hopper 4 storing the rubber blocks, and take the heat emitted by the rubber blocks away from the surface of the rubber blocks through the cold air, thereby accelerating the heat dissipation of the rubber blocks; and the transfer hoppers 4 arranged at intervals on the frame 1 also increase the space between the rubber blocks, thereby increasing the ventilation effect between the rubber blocks and improving the ventilation capacity.

[0026] In some technical schemes of the utility model, the driving mechanism includes two groups of transmission parts, which are symmetrically arranged in the frame 1. The transmission parts include two transmission sprockets 6 and chains 5 which are respectively rotatably arranged on the frame 1. The chains 5 are connected end to end in a ring shape and are sleeved on the two transmission sprockets. The two ends of the material transfer hopper 4 are respectively connected to the chains 5 located in the two transmission parts. The two opposite transmission sprockets 6 located in the two groups of transmission parts are connected through transmission shafts, and the transmission shafts are installed in the frame 1 through mounting seats and load-bearing bearings, which can ensure the stability and consistency of the two groups of transmission parts when transmitting the material transfer hopper 4, and improve the stability of the equipment during operation; the material transfer hopper 4 is fixed by bolts on the links of the two chains 5 which are connected end to end in a ring shape.

[0027] Preferably, a plurality of engaging teeth 12 are disposed around the outer circumferential wall of the transmission wheel, and a portion of the engaging teeth 12 is embedded in the holes on the chain 5, which can increase the matching strength between the two.

[0028] In some technical solutions of the utility model, a plurality of heat dissipation pipes 17 are embedded on the outer wall of the material transfer hopper, and the heat dissipation pipes 17 are filled with heat dissipation medium. The heat dissipation pipes 17 are arranged based on the principle that the heat absorption and heat release of an object are relative. Whenever there is a temperature difference, heat will inevitably be transferred from a high temperature to a low temperature. There are three ways of heat transfer: radiation, convection, and heat conduction, among which heat conduction is the fastest. That is, the heat dissipation material utilizes the liquid in the heat pipe to evaporate in the heat pipe and then dissipate in the cavity formed by the heat pipe, so that the temperature difference between the two ends of the heat pipe is large, so that the heat is quickly conducted inside the heat pipe; the specific structure of the heat dissipation pipe 17 is composed of a tube shell, a liquid wick and an end cover; the manufacturing method is to evacuate the inside of the heat pipe into a negative pressure state, and then fill it with a suitable liquid, which has a very low boiling point and is easy to evaporate; a liquid wick is provided on the inner wall of the cavity, and the liquid wick is composed of a capillary porous material; one end of the heat pipe is the evaporation end, and the other end is the condensation end; when one end of the heat pipe is heated, the liquid in the capillary evaporates rapidly, and the vapor flows to the other end under a small pressure difference, and releases heat and condenses into liquid again; the liquid then flows back to the evaporation section along the porous material by the action of capillary force, and the cycle continues; the heat is transferred from one end of the heat pipe to the other end, and this cycle is carried out quickly, and the heat can be conducted continuously. In this way, when the exhaust pipe 10 can guide the cold air input by the air supply device 2 to the transfer hopper 4 storing the rubber blocks, the heat emitted by the heat dissipation pipe 17 is taken away from the transfer hopper 4. The provision of the heat dissipation pipe 17 can accelerate the heat dissipation capacity of the transfer.

[0029] In some technical solutions of the utility model, a solenoid valve is provided on the output end of the exhaust pipe and connected thereto. The solenoid valve can adjust the output gas volume and output gas pressure of the exhaust pipe according to the actual situation on site, provide appropriate heat dissipation adjustment for the transfer hopper 4, and avoid the exhaust pipe outputting too much or too little gas volume, which cannot provide appropriate cooling conditions for the rubber block.

[0030] In some technical solutions of the utility model, the outer wall of the material transfer hopper is provided with heat dissipation fins 9 arranged in an array. The heat dissipation fins 9 can increase the heat dissipation area of ​​the material transfer hopper; thus, when the exhaust pipe 10 can guide the cold air inputted thereto by the air supply device 2 to the material transfer hopper 4 where the rubber blocks are stored, the heat dissipated by the heat dissipation conduit 17 is taken away from the material transfer hopper 4, and the heat dissipation conduit 17 can accelerate the heat dissipation capacity of the material transfer.

[0031] In some technical solutions of the utility model, a heat dissipation roller 15 connected to the transmission sprocket is rotatably provided on the frame 1, a plurality of liquid discharge ports 16 are provided on the outer wall of the heat dissipation roller 15, a water storage chamber connected to the liquid discharge port 16 is provided inside the heat dissipation roller 15, and a booster device 3 connected to the water storage chamber is provided on the frame 1. The driven gear 14 provided on the heat dissipation roller 15 and the driving gear 13 provided on the transmission sprocket are meshed with each other for transmission, at which time the liquid in the water storage chamber in the heat dissipation roller 15 is thrown out from the liquid discharge port 16 by the centrifugal force generated by the heat dissipation roller 15, and the booster device 3 is used to apply air pressure to the water storage chamber, increasing the initial velocity of the liquid discharged from the liquid discharge port 16, acting on the outer wall of the transfer hopper 4, thereby accelerating the heat dissipation effect of the transfer hopper 4.

[0032] Preferably, a nozzle is provided in the liquid discharge port 16 , and the nozzle can atomize the liquid under the pressure of the boosting device 3 , thereby improving the heat dissipation effect of the transfer hopper 4 .

[0033] In some technical solutions of the utility model, a diffuser bin 7 is installed on the frame 1, and an exhaust hole is provided on the diffuser bin 7, and an exhaust fan is provided in the exhaust hole. The upward air carrying a large amount of heat can be guided to prevent the heat from accumulating above the discharge hopper and being unable to be discharged, thereby affecting the heat dissipation effect of the rubber block; the diffuser bin 7 can be covered above the frame 1 to form a heat dissipation channel with the frame 1. When the transfer hopper 4 carrying the rubber block moves obliquely upward along the frame 1 under the drive of the driving mechanism, the rubber block continues to perform heat dissipation in the heat dissipation channel, which speeds up the heat dissipation effect and avoids the subsequent process from affecting the operation progress of the subsequent process due to a long heat dissipation time.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
