Description

Technical Field

[0001] The utility model relates to the technical field of rubber strip extrusion dies, in particular to a rubber strip extrusion die. Background Art

[0002] At present, rubber strips are a kind of strip-shaped colloid used for bonding, repairing or applying glue to tires and treads. It combines a unique cold-resistant and heat-resistant process formula and has excellent airtightness. It enables the repaired tires to adapt to various road environments around the clock, effectively improves the wear resistance and service life of tire retreading, and makes the retreaded tires more beautiful.

[0003] Among them, sealing strips play an important role in waterproofing, sealing and energy saving in doors and windows, as well as sound insulation, dustproofing, antifreeze and warmth preservation. They must have strong tensile strength, good elasticity, and relatively good temperature resistance and aging resistance. Most of the sealing strips on the market are produced and processed through extrusion molds. After the extruder extrude the shaping raw materials, the raw materials will be formed into the desired shape under the shaping of the die hole of the extrusion mold.

[0004] However, it is difficult to quickly cut the extruded sealing strips into fixed lengths when they are extruded through an extrusion die. Most of the processes on the market collect the extruded strips and then cut them into fixed lengths, which increases the processing steps. Therefore, a new technical solution needs to be designed to solve the problem, which can cut the strips into fixed lengths while they are being extruded. Utility Model Content

[0005] The utility model aims to provide a rubber strip extrusion die, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber strip extrusion die, comprising an extrusion die, a mounting frame is fixedly installed on one side of the extrusion die, a filter box is rotatably installed on one side of the middle part of the mounting frame, a plurality of groups of equally spaced rollers are rotatably installed on the top of the filter box, and a positioning shearing mechanism is installed on one side of the outer wall of the extrusion die;

[0007] The positioning and shearing mechanism includes a mounting ring detachably mounted on one side of the extrusion die, a support frame fixedly mounted on the top of the mounting ring, an electric push rod fixedly mounted on one side of the top of the support frame, a fixing seat fixedly mounted on the other end of the electric push rod, a cutting knife fixedly mounted on the bottom of the fixing seat, and a distance measuring sensor fixedly mounted on one side of the mounting frame.

[0008] As an optional solution of the technical solution of the present application, the distance measuring sensor corresponds to the discharge port of the extrusion die, and the cutting knife is in contact with one side of the extrusion die.

[0009] As an optional solution of the technical solution of the present application, a motor is fixedly installed in the middle of the other side of the mounting frame, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed on one side of the filter box, which can drive the filter box to rotate.

[0010] As an optional solution of the technical solution of the present application, the outer wall of the mounting ring is provided with a plurality of groups of equidistantly distributed positioning holes, and each group of the positioning holes is threadedly connected with an adjusting bolt, so that the mounting ring can be adjusted.

[0011] As an optional solution to the technical solution of the present application, a collecting box is fixedly installed at the bottom of the mounting frame, a liquid pump is fixedly installed on one side of the collecting box, the outlet port of the liquid pump is connected to the nozzle through a conduit, and the nozzle is distributed on the top of the filter box to cool the rubber strip.

[0012] As an optional solution to the technical solution of the present application, limiting holes are provided on both sides of the support frame, limiting rods are movably installed in the two groups of limiting holes, and the bottoms of the two groups of limiting rods are fixedly installed on the top of the fixing seat, so as to limit the fixing seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application can detect the distance between the extruded rubber strip and the distance measuring sensor by positioning the distance measuring sensor in the shearing mechanism. When the extruded rubber strip reaches the specified distance from the distance measuring sensor, the signal can be transmitted to the control processor, which in turn drives the electric push rod on the top of the support frame and the motor on one side of the mounting frame, which not only drives the cutting knife at the bottom of the fixed seat to quickly cut the rubber strip to a fixed length, but also can synchronously rotate the filter box to quickly discharge the cut rubber strip.

[0015] 2. In the technical solution of the present application, a liquid pump is fixedly installed on one side of the interior of the collecting box, and the outlet port of the liquid pump is connected to the nozzle through a conduit. When the high-temperature rubber strip is slowly extruded from the extrusion die, the liquid pump inside the collecting box is driven to transport the cooling water inside the collecting box to the nozzle. In conjunction with the multiple groups of nozzles installed on the piping, the high-temperature rubber strip can be cooled and shaped. At the same time, due to the high spacing between the filter box and the collecting box, the collecting box can have a better heat dissipation effect when recycling the cooling water, thereby ensuring that the cooling water always remains at a low temperature and can continuously cool the rubber strip.

When the extruded rubber strip reaches the specified distance from the distance sensor 25, the signal can be transmitted to the control processor, which in turn drives the electric push rod 22 on the top of the support frame 21 and the motor 14 on the side of the mounting frame 11, which not only drives the cutting knife 24 at the bottom of the fixing seat 23 to quickly cut the rubber strip to a fixed length, but also can synchronously rotate the filter box 12 to quickly discharge the cut rubber strip.

[0024] In this technical solution, after the high-temperature rubber strip is slowly extruded from the extrusion die 1, the liquid pump 31 inside the collection box 3 is driven to transport the cooling water inside the collection box 3 to the nozzle 32. In conjunction with the multiple groups of nozzles installed on the piping, the high-temperature rubber strip can be cooled and shaped. At the same time, due to the high spacing between the filter box 12 and the collection box 3, the collection box 3 has a better heat dissipation effect when recycling the cooling water, ensuring that the cooling water always remains at a low temperature, and the rubber strip can be continuously cooled.

[0025] In some technical solutions, limiting holes 33 are provided on both sides of the support frame 21, and limiting rods 34 are movably installed in the two groups of limiting holes 33.

[0032] When in use, the high-temperature rubber strip is first slowly extruded through the extrusion die 1, and a plurality of equally spaced rollers 13 are rotatably installed on the mounting frame 11 on one side to pull the extruded rubber strip, and at the same time, the distance sensor 25 in the positioning shearing mechanism can be used to detect the distance between the extruded rubber strip and the distance sensor 25. When the extruded rubber strip and the distance sensor 25 reach a specified distance, a signal can be transmitted to the control processor to sequentially drive the electric push rod 22 on the top of the support frame 21 and the motor 14 on one side of the mounting frame 11, which not only pushes the cutting knife 24 at the bottom of the fixing seat 23 to quickly cut the rubber strip to a fixed length, but also can synchronously rotate the filter box 12, The cut rubber strips are discharged quickly, and a liquid pump 31 is fixedly installed on one side of the collecting box 3, and the outlet port of the liquid pump 31 is connected to the nozzle 32 through a conduit. When the high-temperature rubber strips are slowly extruded from the extrusion die 1, the liquid pump 31 inside the collecting box 3 is driven to transport the cooling water inside the collecting box 3 to the nozzle 32. In conjunction with the multiple groups of nozzles installed on the piping, the high-temperature rubber strips can be cooled and shaped. At the same time, due to the high spacing between the filter box 12 and the collecting box 3, it is ensured that the collecting box 3 has a better heat dissipation effect when recycling the cooling water, and the cooling water is kept at a low temperature, so that the rubber strips can be continuously cooled.
