Description

Technical Field

[0002] Tire rubber is the main material that makes up the tire. It is composed of multiple ingredients, including natural rubber and synthetic rubber. The main ingredient in tire rubber is rubber. Usually, the ratio of rubber in the formula rubber will exceed 50%. The rubber used in tires is divided into two categories: natural rubber and synthetic rubber. The flow test of rubber is that the fluidity of rubber in the production process directly affects the quality of the product. Through flow testing, the correct production process can be formulated, production efficiency can be improved, and the occurrence of product defects can be reduced. The equipment used for rubber flow testing is the melt flow rate meter, which melts the rubber and then calculates the flow performance of the tire rubber through the time and speed of the melted rubber flowing out.

[0003] When testing the flow properties of current tire rubber, the melt flow rate meter used needs to first fix the die into the material hole of the furnace, and then compact the rubber with a compaction rod, then insert the weight rod and put weights on the rod to simulate the actual pressure environment, then melt the rubber, wait for the melted rubber to be squeezed out of the die, and then cut the extruded rubber at fixed intervals to obtain uniform rubber segments, and weigh and calculate them to confirm the flow properties of the rubber;

[0004] However, current melt flow rate meters require multiple manual operations during use, including compacting the rubber material, assembling the counterweights, and cleaning the compaction rod and the weight rod after the test is completed.

[0015] The second part of the present invention provides the following technical solution, a tire rubber flow detection method, applied to the tire rubber flow detection device, comprising the following steps:

[0016] S1. First, prepare the tire rubber particles, then push the push-pull rod toward the heating furnace, and then put the die through the top of the material hole, then start the machine to set parameters and preheat, and after the preheating temperature reaches the set value, put the tire rubber particles into it through the material hole;

[0017] S2. After the tire rubber particles are added into the material hole, the No. 1 motor is started to drive the switch plate to rotate, and the electric telescopic rod is rotated to the top of the material hole. Then the electric telescopic rod is started to drive the pressing block to move into the material hole and compact the tire rubber particles. At this time, the tire rubber particles are preheated. After the preheating is completed, the electric telescopic rod drives the pressing block to move upward and reset;

[0018] S3, the No. 1 motor starts again, driving the switch plate to continue to rotate, rotating the hydraulic pump to the top of the material hole, and then the hydraulic pump starts to push the hydraulic rod into the material hole. After the hydraulic rod is inserted into the material hole, pressure is applied to the heated tire rubber material, and then the tire rubber material melts and flows out through the die at the bottom of the material hole. Then the electric cutter starts to cut at intervals, cutting the extruded tire rubber material into rubber bodies of uniform length, and then weighing the cut rubber bodies to obtain the flow data of the rubber material;

[0019] S4. After a certain number of tire rubber inspections are completed, the pressure block and the hydraulic rod need to be cleaned. When the hydraulic rod rises and resets, the melted attachments on its surface can be scraped off by the scraper ring. When cleaning is required, the No. 1 motor is started to drive the switching plate to rotate so that the two ends of the switching plate are aligned with the inner concave plate. Then the electric telescopic rod and the hydraulic pump move to the bottom of the inner concave plate in the moving groove through the movable block. At this time, the pressure block enters the No. 1 cleaning box for cleaning, and the hydraulic rod enters the No. 2 cleaning box for cleaning.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention configures the compaction rod and the weight rod into an electric telescopic rod and a hydraulic pump, and then integrates the two into a frame arranged above the heating furnace. By configuring a switching plate, the compaction and pressure switching are automatically performed, so that the detection device is more convenient and efficient in detecting the flow of the rubber material.

[0022] 2. In the present invention, when the electric telescopic rod above the pressing block for pressing enters the material hole, the electric telescopic rod does not contact the inner wall of the material hole, thereby reducing the problem of adhesion. When the hydraulic rod rises and resets, the scraper ring scrapes its surface, thereby conveniently cleaning the surface of the hydraulic rod, so that the compaction and pressing parts of the device do not need to be cleaned frequently, so that the detection device can continuously and efficiently perform detection, thereby improving the detection work efficiency of the device;

[0023] 3.

[0041] Example 2

[0042] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8 Further improvements have been made on the basis of Example 1:

[0043] A through hole is formed inside the switch plate 10 near the two movable grooves 12, and a connecting rod 21 is rotatably connected inside the through hole of the switch plate 10. Both ends of the connecting rod 21 are embedded with movable threaded rods 22 for telescopic sliding. A transmission groove 23 is formed on the side wall of the vertical plate 7 relative to the movable groove 12, and a fixed threaded rod 24 is rotatably connected inside the transmission groove 23. The top of the transmission groove 23 is parallel to the cross plate 8, and through holes are formed at both ends of the cross plate 8, and the transmission groove 23 is connected to the through hole of the cross plate 8.

A spring 27 is fixedly connected between the side of the limit plate 26 close to the telescopic groove 25 and the inner groove wall opposite to it, and an electromagnetic column 28 is fixedly connected to the inner groove wall of the inner end of the telescopic groove 25. The limit plate 26 is made of magnetic metal. When the pressure block 15 and the hydraulic rod 17 are cleaned, they need to be moved out of the No. 1 cleaning box 19 and the No. 2 cleaning box 20. At this time, the No. 2 motor 34 is started to drive the rotating rod 33 to rotate, and then the movable threaded rod 22 and the fixed threaded rod 24 are driven to rotate through the meshing transmission of the transmission disk 31 and the transmission belt 32. The above two are connected and rotated through the connecting rod 21, and then the movable threaded rod 22 and the fixed threaded rod 24 are driven to rotate. The threaded rod 24 drives the movable block 13 to move from the movable groove 12 under the inner concave plate 11 to the movable groove 12 under the switching plate 10. During the process, the movable block 13 is ensured to be stable by the sliding of the slide plate 35 and the slide groove 36. After the movable block 13 moves into the movable groove 12 under the switching plate 10, the electromagnetic column 28 is powered off. At this time, the spring 27 rebounds, causing the limit plate 26 and the movable threaded rod 22 to move into the telescopic groove 25 and be blocked by the convex ring 45. At this time, the movable threaded rod 22 and the fixed threaded rod 24 move away from each other, and the limit plug 29 and the limit slot 30 are separated, so that the electric telescopic rod 14 and the hydraulic pump 16 are moved and positioned to the circular path position of the material hole 6, so that the pressing block 15 and the hydraulic rod 17 are aligned with the material hole 6, and vice versa, the movable threaded rod 22 and the fixed threaded rod 24 can be plugged and fixed.

The outer sides of the two transmission discs 31 on the same side are meshed and connected with a transmission belt 32. A second motor 34 is bolted to the outer wall of one side of the vertical plate 7 relative to the end of the rotating rod 33. The output end of the second motor 34 penetrates the side wall of the vertical plate 7 and is fixedly connected to the end opposite to the rotating rod 33. When the movable threaded rod 22 is plugged and docked with the end of the fixed threaded rod 24, the rotating rod 3 is driven by the second motor 34. 3 is rotated, the rotating rod 33 can transmit power through the transmission disc 31 and the transmission belt 32, and then the rotating rod 33 drives the two fixed threaded rods 24 to rotate synchronously in the transmission groove 23, and then the fixed threaded rods 24 and the movable threaded rods 22 on both sides can rotate synchronously, driving the two movable blocks 13 to move synchronously toward or away from each other in the movable groove 12, so that the electric telescopic rod 14 and the hydraulic pump 16 can be synchronously driven to synchronously enter the No. 1 cleaning box 19 and the No. 2 cleaning box 20, or synchronously move to the position of the movable threaded rod 22, and synchronously position and align the circular path of the material hole 6.

[0047] Two limit rods 46 are fixedly connected to one side of the limit plate 26 near the opening of the telescopic slot 25. A convex ring 45 is provided on the outer side of one end of the movable threaded rod 22 near the limit plate 26. The other end of the limit rod 46 penetrates the outer wall of the end of the connecting rod 21 and is fixedly connected to the opposite side of the convex ring 45. When the movable block 13 moves to the outside of the movable threaded rod 22, the convex ring 45 is used to block and position it, so that the pressure block 15 and the hydraulic rod 17 can be accurately aligned with the material hole 6. When the movable threaded rod 22 slides in the telescopic slot 25, the limit rod 46 penetrates and slides with the end of the connecting rod 21, so that the movable threaded rod 22 moves stably. At the same time, the connecting rod 21 and the movable threaded rod 22 can rotate synchronously through the blocking of the limit rod 46.

[0051] Application Examples

[0052] This embodiment is applied to the above-mentioned embodiments 1-3, with reference to Fig.10 ;

[0053] After testing the flow performance of tire rubber, the corresponding tire is produced. In tire design, the flow of rubber has certain requirements on the rationality of the size design of tire rubber.

[0054] Specifically, current tires are mainly composed of skeleton materials and rubber semi-components. During the tire development process, the type of skeleton material is selected according to the tire specifications and load index size, and its thickness is fixed. The size design of rubber semi-components such as treads and sidewalls is mostly determined based on empirical formulas. If the size design of the treads and sidewalls is improper, when the fit with the mold is not high during the vulcanization process, relative mold flow will occur, resulting in unreasonable distribution of finished tire materials, which in turn leads to quality problems in the use of tires. In the prior art, the method of marking the surface of the tire embryo is often used to observe the flow of the rubber material. This method only has a certain indication effect on the flow of the rubber material on the surface of the tire embryo, and cannot detect the flow of the rubber material inside. Rubber itself is a poor conductor of heat. During the vulcanization process of the tire, there is a temperature difference between the surface and the inside of the tire embryo, and there is a large difference in the flow of the rubber material inside and outside.

[0055] Therefore, after the fluidity test of the tire rubber is completed, the rubber is applied to the actual design and processing steps. It is necessary to use the vulcanization test to evaluate the rationality of the rubber size design. The specific test method is as follows:

[0056] S1. First, select the rubber of two tire sections and paste the grid paper on the tread joint of the rubber. The grid paper can be used as a reference mark. Then apply a layer of release agent. The role of the release agent is to prevent the tread joints from sticking to each other after docking, and to enable the rubber to flow relatively freely during the vulcanization process.

[0057] S2. After the tread joint is butt-jointed, it is compacted by the equipment. The compaction starts from a relatively small initial pressure of 0.5-1MPa, and gradually increases to a final pressure of 2-5MPa after 10-30s, and is maintained for an appropriate time such as 30-60s, so that the joint is fully compacted to ensure that the rubber at the tread joint is tightly combined. This step is to ensure the fitting quality of the tread joint so that the rubber can form a whole during the vulcanization process, and then vulcanization is carried out. According to the formula of the tire tread rubber and product requirements, the vulcanization temperature (such as 140-180℃), pressure (such as 2-10MPa) and time (such as 10 to 30 minutes) and other parameters are set to complete the vulcanization process.

[0058] S3. After vulcanization, take out the tire tread. Use a cutting tool to carefully cut it along the tread joint. Keep the cut flat during the cutting process and try to avoid causing additional damage to the grid paper and rubber to affect the observation effect. Then carefully observe the distance and density between the grids after cutting. You can use a measuring tool (such as a caliper) to measure the grid spacing and record the grid spacing data at different positions. At the same time, intuitively judge whether the grid density is uniform and whether there are local dense or sparse areas. According to the observation and measurement results, you can analyze the flow trend of the rubber and make a judgment on whether the tire rubber size design is reasonable.

[0059] Using the above-mentioned vulcanization test process, when abnormal rubber flow is observed, for the rubber shape design, you can consider adjusting the parameters such as the thickness, width or shape of the rubber, and according to the flow of the rubber, appropriately adjust the vulcanization parameters such as temperature, pressure and time. For example, when the rubber flow is insufficient, you can appropriately increase the vulcanization temperature or pressure to promote the flow of the rubber. Therefore, through this applied vulcanization test, the tire rubber can be further optimized in the actual design and processing process, thereby improving the quality of tire products.
