Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of waterproof coiled material production equipment, and in particular relates to a waterproof coiled material base overlapping device. Background Art
[0002] The waterproof material product made by impregnating asphalt or polymer waterproof materials on the base is provided in the form of rolls, which are called waterproof rolls.
[0003] The rolled PET tire base material is unrolled and transferred to the impregnation production equipment for production and processing into products. When the PET tire base material is unrolled and transferred, in order to overlap the previous roll of tire base material with the next roll of tire base material, a tire base roll storage device will be set at the front end of the transmission, that is, close to the unrolling position, to facilitate manual overlapping of the end of the tire base material at the end of unrolling with the front end of the tire base material to be unrolled next time. At present, the overlapping method of PET tire base materials is: manually cut the end and the front end of the tire base neatly and then connect them together, and use high-temperature tape to bond the end and the front end. This overlapping method requires neat cutting before overlapping and someone to assist in fixing the front and back tire base materials during bonding, which is time-consuming and labor-intensive; and the overlapping effect is affected by the operator's experience, which is not conducive to large-scale and standardized production of products. Summary of the invention

[0005] To achieve the above object, the present invention is implemented through the following technical solutions: A waterproof coiled material base overlapping device, comprising a support platform, a base fixing component and a hot pressing component; The tire base fixing assembly includes: multiple rows of negative pressure suction nozzles, through holes, L-shaped push rods, rotating shafts, connecting rods and electric push rods; through holes are provided through the upper and lower end surfaces of the support platform, and an L-shaped push rod is provided at the lower end of each through hole; the rotating shaft passes through the turning part of the L-shaped push rod and the L-shaped push rod is rotatably connected to the rotating shaft, and the lower part of the L-shaped push rod is fixedly connected through the connecting rod; the lower end of one of the L-shaped push rods is hinged to the output end of the electric push rod, and the bottom of the electric push rod is rotatably connected between the two vertical plates; The hot pressing assembly includes: a cylinder, an electric heating platen, a horizontal block, a vertical rod, a base and a driving motor; the vertical rod is rotatably connected to the base, the upper end of the vertical rod is connected to the horizontal block, the lower end of the horizontal block is connected to the cylinder, and the output end of the cylinder is connected to the electric heating platen; the vertical rod is fixedly connected to a driven gear, the driving motor is installed on the base, and a driving gear meshing with the driven gear is installed on the output shaft of the driving motor.
[0006] Furthermore, there are six rows of negative pressure suction nozzles, three rows of which are used to fix the end of the tire base at the end of unwinding, and the other three rows are used to fix the front end of the newly unwinding tire base; the hot pressing area is between the negative pressure suction nozzles for different purposes.
[0007] Furthermore, the driving motor is a servo motor.
[0008] Through the above technical solution, the present invention can at least achieve the following beneficial effects: The invention is used to overlap the waterproof coiled material base, and compared with the traditional method, no cutting is required; at the same time, the entire overlapping process only requires the front end and the end of the base to be positioned, and the overlapping process no longer relies on the operator's experience, which is conducive to the standardization and large-scale production of the product.

[0011] Embodiment, as attached Figure 1-2 As shown, a waterproof coiled material base overlapping device comprises a support platform 1, a base fixing component and a hot pressing component; The tire base fixing assembly includes: multiple rows of negative pressure suction nozzles 2, through holes 3, L-shaped push rods 4, rotating shafts 5, connecting rods and electric push rods 6; through holes 3 are provided through the upper and lower end surfaces of the support platform 1, and an L-shaped push rod 4 is provided at the lower end of each through hole 3; the rotating shaft 5 passes through the turning part of the L-shaped push rod 4 and the L-shaped push rod 4 is rotatably connected to the rotating shaft 5, and the lower part of the L-shaped push rod 4 is fixedly connected by a connecting rod 15; the lower end of one of the L-shaped push rods 4 is hinged to the output end of the electric push rod 6, and the bottom of the electric push rod 6 is rotatably connected between the two vertical plates 7; The hot pressing assembly includes: a cylinder 8, an electric hot pressing plate 9, a horizontal block 10, a vertical rod 11, a base 12 and a driving motor 13; the vertical rod 11 is rotatably connected to the base 12, the upper end of the vertical rod 11 is connected to the horizontal block 10, the lower end of the horizontal block 10 is connected to the cylinder 8, and the output end of the cylinder 8 is connected to the electric hot pressing plate 9; the vertical rod 11 is fixedly connected to a driven gear, the driving motor 13 is installed on the base 12, and a driving gear meshing with the driven gear is installed on the output shaft of the driving motor 13, and the driving motor 13 can be a servo motor.
[0012] There are six rows of negative pressure suction nozzles 2, three rows of which are used to fix the end of the tire base after unwinding, and the other three rows are used to fix the front end of the newly unwinding tire base; the hot pressing area 14 is between the negative pressure suction nozzles 2 for different purposes.
[0013] Working principle of the present invention: When the end and front of the coil need to be overlapped, the end of the coil is pulled to the hot pressing area 14 of the support platform 1, and the end of the base is fixed with three rows of negative pressure nozzles 2. At this time, the row of negative pressure nozzles 2 close to the through hole 3 releases the end of the base, and the remaining two rows of negative pressure nozzles 2 continue to suck the end of the coil base; then the electric push rod 6 starts to work, driving the L-shaped push rod 4 to rotate around the rotating shaft 5 and then pass through the through hole 3 to lift the released end of the coil base; the operator then pulls the front end of the next coil base onto the support platform 1, and uses the other three rows of negative pressure nozzles 2 to fix it in place, and the front end of the coil base extends into the hot pressing area 14.
[0014] The cylinder 8 drives the electric heating platen 9 connected to its output end to first heat the upper surface of the front end of the coil in the hot pressing area 14. After the heating is completed, the electric push rod 6 and the cylinder 8 are reset, and the electric push rod 6 drives the L-shaped push rod 4 to fall, so that the end of the coil base falls to the upper surface of the end of the base coil; the aforementioned negative pressure suction nozzle 2 close to the through hole 3 now works again to suck the coil base, so that the end of the base is more stably located on the upper surface of the front end of the base; at this time, the cylinder 8 drives the electric heating platen 9 to move downward again, hot-presses the coil base, so that the preheated front and end of the tower base are connected together.
[0015] After the hot pressing is completed, the driving motor 13 drives the vertical rod 11, the horizontal block 10, the cylinder 8 and the electric hot pressing plate 9 to rotate, so that they are away from the support platform 1, to prevent the horizontal block 10, the cylinder 8 and the electric hot pressing plate 9 from affecting the subsequent transmission of the overlapped coil base. A travel switch can be set for the rotation and reset of the vertical rod 11, the horizontal block 10, the cylinder 8 and the electric hot pressing plate 9, so that the rotation ends when the rotation reaches the required position. This is a setting that can be made by technicians in this field according to needs, and will not be repeated here.
[0016] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
