Description

Technical Field

[0001] The present invention relates to the technical field of material detection, and in particular to a tire rubber material flow detection device and method. Background Art

[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 currently used for rubber flow testing is a melt flow rate meter, which melts the rubber and then calculates the flow properties 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 compounds, a melt flow rate meter is used. The die is first fixed to the material hole of the furnace. The rubber compound is then compacted using a compacting rod. A weight rod is then inserted and a weight is placed on the rod to simulate a realistic pressure environment. The rubber compound is then melted and allowed to extrude from the die. The extruded rubber compound is then cut at fixed intervals to obtain uniform segments. These segments are then weighed to confirm the flow properties of the rubber compound.

[0004] However, current melt flow rate meters require multiple manual operations during use, including compacting the rubber material, assembling the counterweight, 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 material flow detection method, using the tire rubber material flow detection device, comprising the following steps:

[0016] S1. First, prepare the tire rubber pellets, 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, set the parameters and preheat. After the preheating temperature reaches the set value, put the tire rubber pellets into the furnace through the material hole;

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

[0018] S3. Motor 1 starts again, driving the switch plate to continue rotating, turning the hydraulic pump to the top of the material hole. The hydraulic pump then starts to push the hydraulic rod into the material hole. After the hydraulic rod is inserted into the material hole, it applies pressure to the heated tire rubber compound, which then melts and flows out through the die at the bottom of the material hole. The electric cutter then starts to cut the extruded tire rubber compound into uniform lengths. The cut rubber compounds are then weighed to obtain the rubber compound flow data.

[0019] S4. After completing a certain number of tire rubber compound tests, the pressure block and hydraulic rod need to be cleaned. When the hydraulic rod rises and resets, the scraper ring can scrape off the melted attachments on its surface. When cleaning is required, the No. 1 motor starts, driving 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 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 compacting rod and the weight rod as an electric telescopic rod and a hydraulic pump, and integrates the two into a frame above the heating furnace. By setting a switch plate, the compaction and pressure switching is automatically performed, making the flow detection process of the rubber material by the detection device more convenient and efficient;

[0022] 2. In the present invention, when the electric telescopic rod above the pressing block for compaction 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, its surface is scraped by the scraper ring, thereby conveniently cleaning the surface of the hydraulic rod. This makes it unnecessary to frequently clean the compaction and pressure components of the device, allowing the detection device to perform detection continuously and efficiently, thereby improving the detection efficiency of the device.

[0023] 3. The present invention provides a No. 1 cleaning box and a No. 2 cleaning box to clean the pressing block, the hydraulic rod and the scraper ring respectively, and the cleaning can be completed without disassembling the structure, thereby making it more convenient and efficient when regularly cleaning attachments.

[0041] Example 2

[0042] Reference Figure 3 、 Figure 4 、 Figure 7 and Figure 8 Further improvements were made based on Example 1:

[0043] A through hole is opened inside the switching plate 10 near the two movable grooves 12, and a connecting rod 21 is rotatably connected inside the through hole of the switching plate 10. Both ends of the connecting rod 21 are embedded with movable threaded rods 22 for telescopic sliding. A transmission groove 23 is opened 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 horizontal plate 8, and through holes are opened at both ends of the horizontal plate 8. The transmission groove 23 is connected to the through hole of the horizontal plate 8.

[0044] Both ends of the connecting rod 21 are provided with a telescopic slot 25, and one end of the movable threaded rod 22 close to the telescopic slot 25 is fixedly connected to a limit plate 26, and the limit plate 26 is adapted to the telescopic slot 25 and slidably connected. A spring 27 is fixedly connected between the side of the limit plate 26 close to the telescopic slot 25 and the inner groove wall opposite thereto, and an electromagnetic column 28 is fixedly connected to the inner groove wall of the telescopic slot 25 near the inner end. 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 removed from 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 plate 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 from the movable groove 12 below the inner concave plate 11 to the movable groove 12 below 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 below 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 are separated, and the limiting plug 29 and the limiting 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 can be 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.

[0045] One end of the movable threaded rod 22 relative to the fixed threaded rod 24 is fixedly connected to the limiting plug 29, and a limiting slot 30 is provided at one end of the fixed threaded rod 24 relative to the movable threaded rod 22. The limiting plug 29 is adapted to be plugged into the limiting slot 30. When the movable threaded rod 22 is energized by the electromagnetic column 28 and magnetized, it produces a like-charge repulsion effect with the limiting disk 26, pushing the movable threaded rod 22 to move in the direction of the fixed threaded rod 24. Then, the limiting plug 29 is inserted into the limiting slot 30, so that the movable threaded rod 22 and the fixed threaded rod 24 can be docked and fixed. Then, the fixed threaded rod 24 can rotate synchronously with the movable threaded rod 22, driving the two movable blocks 13 to move synchronously in the movable groove 12.

[0046] The two transmission grooves 23 are rotatably connected with the inner groove wall of the through hole of the horizontal plate 8, and the fixed threaded rod 24 is fixedly connected with a transmission disk 31 at one end close to the transmission groove 23 and the relative position of the rotation rod 33. The outer sides of the two transmission disks 31 on the same side are meshed with a transmission belt 32. The outer wall of one side of the vertical plate 7 relative to the end of the rotation rod 33 is bolted with a No. 2 motor 34. The output end of the No. 2 motor 34 passes through the side wall of the vertical plate 7 and is fixedly connected to the end opposite to the rotation rod 33. When the movable threaded rod 22 is plugged into and docked with the end of the fixed threaded rod 24, the No. 2 motor 34 is started to drive the rotation rod 3 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 rod 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 as to synchronously drive the electric telescopic rod 14 and the hydraulic pump 16 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 them on 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 passes through 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, it is blocked and positioned by the convex ring 45, 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 slides through 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.

[0048] Example 3

[0049] Reference Figure 6 , further improvements were made on the basis of Example 1:

[0050] The bottom of the inner groove of the No. 1 cleaning box 19 and the No. 2 cleaning box 20 are both provided with a circular groove, and a cleaning ring 37 is rotatably connected inside the circular groove. A cleaning brush 38 is fixedly connected to the inner arc of the cleaning ring 37. The bottom of the cleaning ring 37 is a closed disc, and a cleaning brush 38 is also provided on the surface of the disc. The top of the cleaning ring 37 of the No. 2 cleaning box 20 is fixedly connected to a scraper 39. The shape of the scraper 39 is adapted to the shape of the scraper ring 18. When the cleaning ring 37 rotates, the outer surface of the scraper ring 18 and the bottom end of the hydraulic rod 17 are scraped in contact. The cleaning ring 37 is fixedly connected to an outer gear ring 40. The No. 1 cleaning box 19 and the No. 2 cleaning box 20 are internally rotatably connected to a gear 41 on one side near the outer gear ring 40. The No. 3 motor 42 is connected to the internal bolts of the No. 1 cleaning box 19 and the No. 2 cleaning box 20 near the bottom of the gear 41. The output of the No. 3 motor 42 The output end is fixedly connected to the bottom of the gear 41. When the pressure block 15, hydraulic rod 17 and scraper ring 18 are cleaned, the electric telescopic rod 14 and the hydraulic pump 16 are moved to the bottom of the inner concave plate 11 in the movable groove 12 through the movable block 13. At this time, the electric telescopic rod 14 and the pressure block 15 move into the No. 1 cleaning box 19, and then the electric telescopic rod 14 is started to drive the pressure block 15 to descend to the inside of the cleaning ring 37. At this time, the No. 3 motor 42 is started to drive the gear 41 to rotate, and then the gear 41 is driven by meshing with the outer gear ring 40. The outer gear ring 40 can drive the cleaning ring 37 to rotate. At this time, the cleaning brush 38 of the inner arc of the cleaning ring 37 can clean the pressure block 15.

At the same time, the scraper 39 cleans the attachments on the surface of the scraper ring 18 and the hydraulic rod 17.

[0051] Application Examples

[0052] This embodiment is applied to the above embodiments 1-3, refer to Figure 10 ;

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

[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, and its thickness is fixed. The size design of rubber semi-components such as the tread and sidewall is mostly determined based on empirical formulas. If the size design of the tread and sidewall is improper, if the fit with the mold is not high during the vulcanization process, relative mold flow will occur, resulting in unreasonable distribution of the finished tire material, which in turn causes quality problems during tire use. In the existing technology, the method of marking the surface of the tire blank 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 tire blank surface, and cannot detect the flow of the rubber material inside the tire blank. Rubber itself is a poor conductor of heat. During the tire vulcanization process, there is a temperature difference between the surface and the interior of the tire blank, and there is a large difference in the flow of the rubber material inside and outside.

[0055] Therefore, after the tire compound fluidity test is completed, the compound is applied to the actual design and processing steps. It is necessary to conduct a 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 grid paper on the tread joint of the rubber section. 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 compound 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, to fully compact the joint and ensure that the rubber at the tread joint is tightly bonded. This step is to ensure the fitting quality of the tread joint and enable the rubber to form a whole during the vulcanization process. Subsequently, vulcanization is carried out. According to the formula of the tire tread rubber compound and product requirements, the vulcanization temperature (such as 140-180℃), pressure (such as 2-10MPa) and time (such as 10-30 minutes) and other parameters are set to complete the vulcanization process.

[0058] S3. After vulcanization is complete, remove the tire tread. Use a cutting tool to carefully cut along the tread joint. Keep the cut smooth during the cutting process and try to avoid causing additional damage to the grid paper and rubber, which will 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 locations. At the same time, intuitively determine whether the grid density is uniform and whether there are locally dense or sparse areas. Based on 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, the thickness, width or shape of the rubber profile can be adjusted for the rubber profile size design. In addition, the vulcanization temperature, pressure and time can be appropriately adjusted according to the flow of the rubber. For example, when the rubber flow is insufficient, the vulcanization temperature or pressure can be appropriately increased to promote the flow of the rubber. Therefore, through this applied vulcanization test, the tire rubber can be further optimized during the actual design and processing process, thereby improving the quality of tire products.
