Description

Technical Field

[0001] The present invention relates to the technical field of rubber extrusion molding, and particularly to a composite molding device for a rubber composite sealing strip. Background Art

[0002] The composite molding of rubber is a production process that mainly combines two or more rubber materials with different properties to obtain a composite material with excellent performance. During production, the two rubbers are respectively extruded through two rubber extruders and are extruded and molded at a composite die head. Then, the molded rubber strip is sent to be vulcanized under high temperature and high pressure conditions to endow it with stable physical and chemical properties. Finally, the vulcanized rubber composite material is processed, such as cutting, grinding, etc., to obtain the required shape and size. The composite molding process of rubber can produce composite materials with excellent performance, such as high strength, high wear resistance, corrosion resistance, etc., and is widely used in fields such as automobiles, machinery, electronics, and construction.

[0003] After the two groups of extruders send the rubber material into the composite die head for extrusion molding, the rubber itself has a high temperature and insufficient material hardness and cannot directly contact the equipment. Therefore, after extrusion from the composite die head, the rubber strip is generally suspended for a certain distance and then carried by a conveyor belt as a traction device to transport the rubber strip to the vulcanization processing area, so that the rubber strip has a certain cooling time to prevent structural collapse or stress deformation.

[0004] However, the running speed of the traction device and the extrusion rate of the extruder are in a dynamic balance state during the actual production process, and their speeds will both fluctuate. When the speed of the traction device is higher than the extrusion speed of the extruder, the traction device will stretch the just-extruded rubber strip, thereby causing the width of the rubber strip to change during the cooling process, affecting the quality and precision of the product. And manual inspection has a certain lag, and often a large number of rubber strips are structurally damaged when the problem is discovered. Moreover, simply relying on manual observation of the width of the rubber strip, it is difficult to determine whether the deformation amount of the rubber strip has exceeded the production requirements. And in the actual production process, the shapes of the produced rubber sealing strips are diverse. Especially for the case where the lower part of the rubber strip is an arc surface or a special-shaped surface, the rubber strip is prone to tipping over during transportation on the traction device, resulting in torsion of the extruded rubber strip. When the rubber strip is not completely cooled, the structure will undergo slight torsional deformation, resulting in a decline in product quality. Summary of the Invention

The lifting frame is driven to move up and down on the lifting lead screw through the transmission of the lifting lead screw and the first transmission nut. The movement of the lifting frame is limited by the lifting limit holes, reducing the vibration amplitude of the lifting frame itself during the movement and improving the stability of the device. The height of the lifting frame is measured by the laser rangefinder and transmitted to the PLC controller for display, facilitating the operator to timely discover whether the heights of the front and rear two groups of lifting frames are consistent and improving the practicability of the device.

When the rubber strip extruded by the composite die head sags or straightens due to the speed difference between the traction device and the extrusion device, the optoelectronic signals emitted by the signal generators on the upper and lower parts of the iron lifting arm will be blocked respectively, that is, the speed gap between the traction device and the extrusion device is too large and exceeds the automatic adjustment range. When the signal receiver cannot receive the signal from the signal generator, the signal receiver transmits the information to the PLC controller to prompt the operator for maintenance, improving the practicability of the device.

[0039] This embodiment is an improvement based on Embodiment 1, including a supporting device and a limiting device. The supporting device is installed on the frame, and the limiting device is installed on the supporting device; the sag amplitude of the rubber strip between the output end of the composite die head 2 and the supporting device during the extrusion process is monitored through the supporting device and the limiting device, preventing the rubber strip from being structurally deformed due to too large a difference in the extrusion rates of the traction device and the composite die head 2, and improving the practicability of the device.

[0040] The supporting device includes a gantry 30, a support body 31, an adjusting lead screw 32, a limiting slider 33, a second transmission nut 34, and a rotating rod 35. A set of gantries 30 are respectively installed at the front and rear of the upper part of the frame. The two sets of gantries 30 are located at the position between the composite die head 2 and the support roller 15. The support body 31 is installed on the upper end surface of the gantry 30, and a scale line 36 is engraved on the side surface of the support body 31.

[0041] A chamber is provided inside the support body 31. The limiting slider 33 is located in the chamber inside the support body 31.

The second transmission nut 34 is installed on the limiting slider 33, and the adjusting lead screw 32 is connected to the limiting slider 33 through the second transmission nut 34.

[0042] The limiting device includes an iron lifting arm 37, a magnet 38, a mounting plate 39, a signal generator 40, and a signal receiver 41. A rectangular hole is provided on the lower end surface of the support body 31. The iron lifting arm 37 is connected to the lower end surface of the limiting slider 33. Vertical rectangular holes are provided on the iron lifting arm 37. Multiple groups of magnets 38 are respectively adsorbed on the outer side surfaces of the two sets of iron lifting arms 37.

[0044] Such as Figures 1 to 10As shown in the figure, when the present invention is working, first select a suitable support roller 15 according to the die structure of the composite die head 2, and rotate it to the upper part of the transverse support arm 9. Then, pass the fixing rod 18 through the circular holes on the rotating arm 14 and the fixing plate 16, and rotate the fixing rod 18 to connect the thread on the fixing rod 18 with the fixing nut 17, so as to fix the fixing rod 18, and further fix the position of the support roller 15. According to the weight per unit length of the rubber strip extruded by the composite die head 2, move the sliding block 10 to a suitable position and fix the position of the sliding block 10 by rotating the fastening bolt 11. Turn on the reduction motor 20 to transmit power to the lifting lead screw 21 to drive the lifting lead screw 21 to rotate. Through the transmission of the lifting lead screw 21 and the first transmission nut 24, drive the lifting frame 22 to move up and down on the lifting lead screw 21, so that the lower part of the guide roller 29 is located below the upper end surface of the conveyor belt 6. Then, turn on the composite extruder 1 to extrude the rubber strip from the composite die head 2. When the extrusion is stable, place the rubber strip in the special-shaped groove on the support roller 15, and then pass the front part of the rubber strip through the lower part of the guide roller 29 and place it on the upper end surface of the conveyor belt 6. Then, turn on the motor 4 to transmit power through the reducer 3 to the connected conveyor roller 5. Through the cooperation of multiple groups of conveyor rollers 5 and the conveyor belt 6, drive the rubber strip to move to the left, and monitor the quality of the guide roller 29 through the pressure sensor 26 and transmit the data to the PLC controller 19 for display. The operator controls the rotation speed of the motor 4 according to the pressure value measured by the pressure sensor 26 so that the pressure value monitored by the pressure sensor 26 is within the preset value range. Then, when the value monitored by the pressure sensor 26 for the guide roller 29 is higher than the preset value range, the PLC controller 19 controls the reduction motor 20 to turn on to lower the height of the guide roller 29 to press the rubber strip, preventing the rubber strip structure from deforming due to excessive sagging of the rubber strip between the support roller 15 and the composite die head 2; when the value monitored by the pressure sensor 26 for the guide roller 29 is lower than the preset value range, the PLC controller 19 controls the reduction motor 20 to turn on to raise the position of the guide roller 29, preventing the rubber strip structure from being stretched and damaged due to excessive internal tension of the rubber strip between the composite die head 2 and the support roller 15; when the rubber strip between the composite die head 2 and the support roller 15 is still sagging or straightened after exceeding the adjustable range of the lifting of the guide roller 29 until it blocks the upper or lower signal receiver 41 from receiving the optoelectronic signal of the signal generator 40, the signal receiver 41 transmits the information to the PLC controller 19 to prompt the operator, and then the equipment can be adjusted and maintained.
