Description

Technical Field

[0001] The utility model relates to the technical field of rubber inner tube extrusion devices, in particular to an environmentally friendly extrusion molding device for a rubber inner tube. Background Art

[0002] Automobile tires usually consist of three parts: outer tube, inner tube and flap. The outer tube is the annular outer shell of the pneumatic tire. Its function is to bear the vehicle load, prevent the inner tube from swelling after inflation, limit the size of the outer edge of the tire, and protect the inner tube from mechanical damage; the inner tube, commonly known as the inner tube, is a circular elastic tube with a tire valve used to maintain the internal pressure of the tire, and the valve is used for inflation; the flap, also known as the lining tape or pressure strip, is an annular tape used to protect the contact surface of the inner tube from rim wear. It is installed between the inner tube and the rim, with a thicker middle part and gradually thinner edges from the inside to the outside.

[0003] However, many existing rubber inner tube extrusion molding devices generally require operators to manually add rubber materials continuously during operation, which is cumbersome and puts a heavy burden on the operator's physical strength. At the same time, once the material is lacking, the thickness of the inner tube may be uneven or even interrupted, thereby affecting the quality of the finished product and the yield rate. In addition, many existing rubber inner tube extrusion devices generally do not have a structure for cooling the die, so the temperature at the die can only be cooled slowly by natural cooling, which reduces the processing efficiency of the device to a certain extent. Utility Model Content

Through the arrangement of a support frame, a conveyor belt and a rubber baffle, an operator only needs to place the rubber material inside a discharge bin. The operation of the conveyor belt cooperates with the rubber baffle to continuously add the rubber material into the extruder, thereby reducing the occurrence of uneven thickness of the inner tube or even interruption due to lack of material. In addition, through the arrangement of a heat dissipation fan and a protective net, not only can the die be cooled by air, thereby improving the processing efficiency of the device, but it can also prevent the operator from accidentally touching the heat dissipation fan with his hands during operation, thereby solving the above-mentioned problem.

[0006] Preferably, a plurality of groups of rubber baffles are fixedly mounted on the outer wall of the conveyor belt in an equidistant array.

[0007] Preferably, second leak-proof plates are fixedly installed at an angle at both the front and rear ends of the top of the support frame.

[0008] Preferably, a feed port is fixedly installed at the top input end of the extruder body, and the feed port is funnel-shaped.

[0009] Preferably, support plates are fixedly installed at the front and rear ends of the right top of the base plate, and mounting openings are opened inside the two groups of support plates. A bracket is fixedly installed inside each group of mounting openings, and a cooling fan is fixedly installed on each group of brackets.

[0010] Preferably, protective nets are fixedly installed on the ends of the two groups of installation openings that are away from each other.

[0011] Preferably, a control panel is fixedly installed at the front end edge of the top of the bottom plate, and the extruder body, the conveyor belt and the heat dissipation fan are all electrically connected to the control panel.

[0012] Preferably, rubber pads are fixedly installed at the four corners of the bottom end of the base plate.

[0013] The working principle and beneficial effects of the utility model are as follows:

In addition, in this device, through the provision of the first leak-proof plate and the second leak-proof plate, in the process of transporting the rubber material to the inside of the extruder, the rubber material that falls at the edge position can fall back into the discharge bin to prevent the rubber material from falling and scattering on the ground and causing certain pollution to the working environment. Finally, the operator can start the set cooling fan through the control panel during the processing, so that it can have a certain cooling effect on the rubber inner tube that has just been made.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, this embodiment proposes an environmentally friendly extrusion molding device for a rubber inner tube, comprising a base plate 1, an extruder body 2 is fixedly installed at the middle position of the top of the base plate 1, a head 3 is fixedly connected to the output end of the extruder body 2, a die 4 is fixedly installed at the right end of the head 3, a support frame 6 is fixedly installed on the right side of the top of the base plate 1, a conveyor belt 7 is fixedly installed at the top of the support frame 6 at an angle, a discharge bin 9 is fixedly installed at the bottom left end of the support frame 6, and a first leak-proof plate 10 is fixedly installed inside the support frame 6 at a position directly below the conveyor belt 7, and is communicated with the discharge bin 9.

[0025] A plurality of groups of rubber baffles 8 are fixedly mounted on the outer wall of the conveyor belt 7 in an equidistant array.

[0026] A second leak-proof plate 11 is fixedly installed at both the front and rear ends of the top of the support frame 6 at an angle.

[0027] A feed port 5 is fixedly mounted on the top input end of the extruder body 2 , and the feed port 5 is funnel-shaped.

[0028] A control panel 18 is fixedly mounted at the front end edge of the top of the base plate 1 , and the extruder body 2 , the conveyor belt 7 and the heat dissipation fan 15 are all electrically connected to the control panel 18 .

[0029] Rubber pads 17 are fixedly installed at the four corners of the bottom end of the base plate 1.

[0030] In this embodiment, when using this device, the operator can first place the prepared rubber material inside the discharge bin 9, and then start the set conveyor belt 7 through the control panel 18. During the operation, the conveyor belt 7 can drive the rubber baffle 8 fixedly installed on the outer surface of the conveyor belt 7 to rotate, so that when the rubber baffle 8 passes through the discharge bin 9, the rubber material can be driven into the funnel-shaped feed port 5, thereby reducing the occurrence of uneven thickness of the inner tube or even interruption due to lack of material, and also reducing the workload of the operator. In addition, in this device, through the setting of the first leak-proof plate 10, the rubber material that is transported through the rubber baffle 8 but does not fall into the feed port 5 can be guided back and dropped back into the discharge bin 9. At the same time, through the setting of the second leak-proof plate 11, the rubber material that falls from the front and rear edges of the rubber baffle 8 can be guided back and dropped into the discharge bin 9, thereby preventing the rubber material from falling and scattering on the ground and causing pollution to the working environment, thereby making the practical usability of this device higher.

[0031] Example 2

[0032] like Figures 1 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that support plates 12 are fixedly installed at the front and rear ends of the top right side of the base plate 1, and mounting openings 13 are opened inside the two groups of support plates 12. A bracket 14 is fixedly installed inside each group of mounting openings 13, and a heat dissipation fan 15 is fixedly installed on each group of brackets 14.

[0033] A protective net 16 is fixedly mounted on one end of the two groups of mounting openings 13 that are away from each other.

[0034] In this embodiment, when using the present device, the operator can start the provided heat dissipation fan 15 through the control panel 18, so that the die 4 can be cooled and dissipated by air, which not only improves the production and molding efficiency of the rubber inner tube, but also extends the service life of the die 4 to a certain extent. In addition, the provision of the protective net 16 fixedly installed at the ends of the two sets of mounting openings 13 away from each other can not only prevent the operator from accidentally touching the heat dissipation fan 15 with his hands during operation and causing unnecessary damage to the operator, but also can reduce the risk of larger external debris being sucked into the interior of the mounting opening 13 during air cooling, thereby causing unnecessary damage to the heat dissipation fan 15, thereby further improving the practical usability of the present device.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
