Description

Technical Field

[0001] The invention belongs to the technical field of rubber processing, and in particular relates to a recycled fluororubber continuous heating and pressurizing vulcanizing machine. Background Art

[0002] In the rubber processing process, vulcanization is a relatively common procedure. There are many kinds of vulcanization equipment used for fluororubber vulcanization according to needs. Among them, the most common one is the column vulcanizer, which is a vulcanization equipment with a column as the core supporting structure, mainly used for the vulcanization molding of rubber products.

[0003] The column type vulcanizing machine generally includes the following structures: The crossbeam is one of the main load-bearing components of the vulcanizer, and it mainly bears bending stress during work.

[0004] The column is the supporting component of the vulcanizer and it bears tensile stress.

[0005] Frames, either modular or fully welded, have components that perform the same functions as columns and beams and are calculated on the same principles.

[0006] The power hydraulic cylinder is a key component of the column vulcanizer, which provides the pressure required for the vulcanization process. The hydraulic cylinder is equipped with a plunger, which bears the pressure of the working fluid and transmits this force to the heating plate of the vulcanizer.

[0007] The vulcanizing machine plate is used to place the model of the vulcanized product, and the plate is used to transfer pressure to the model and heat the model.

[0008] Traditional column-type vulcanizers generally output rubber parts after a single hot-press vulcanization. It is necessary to check whether the vulcanization is complete after the parts are output. If the vulcanization is not complete, it needs to be vulcanized again.

[0009] Secondly, during the vulcanization process, a layer of colloid will be produced on the surface of the rubber parts. During the second vulcanization process, this layer of colloid will affect the vulcanization process, resulting in low vulcanization completion and affecting the vulcanization efficiency.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0026] like Figure 1-Figure 14 As shown, a recycled fluororubber continuous heating and pressurizing vulcanizer comprises a vulcanizing machine body 1, a vertical pushing assembly 2 installed at the discharge end of the vulcanizing machine body 1, an adsorption conveyor belt 3 installed at the power output end of the vertical pushing assembly 2, and a pressure measuring platform 4 installed on the top of the vertical pushing assembly 2 for extrusion testing the fluororubber. The adsorption conveyor belt 3 can adsorb and transport the rubber parts after the initial vulcanization, and at the same time, cooperate with the pressure measuring platform 4 to perform an extrusion test on the rubber parts to determine whether they are completely vulcanized. If they are not completely vulcanized, they will be subjected to secondary vulcanization. If they are completely vulcanized, they will be output.

[0027] See attached Figure 1 and Figure 2The vulcanizing machine body 1 includes a base 11, columns 13 vertically fixedly installed at the four corners of the base 11, and a hydraulic cylinder 12 fixedly installed at the center of the top surface of the base 11. The top of the column 13 is threadedly connected with an upper pressing platform 15, and its height can be adjusted as needed to cooperate with vulcanized parts of different thicknesses, and an upper vulcanizing plate 16 is fixedly installed on the bottom surface of the upper pressing platform 15. A lower pressing platform 14 is fixedly installed at the power output end of the hydraulic cylinder 12. The four corners of the lower pressing platform 14 are slidably sleeved on the columns 13. Track beams 17 are fixedly installed on both sides of the top surface of the lower pressing platform 14, and a lower movable vulcanizing plate 18 used in conjunction with the upper vulcanizing plate 16 is slidably installed between the track beams 17. In this way, the lower movable vulcanizing plate 18 can be vertically pushed by the hydraulic cylinder 12 to cooperate with the upper vulcanizing plate 16, and the rubber parts placed between the two can be heated and pressurized for vulcanization.

[0028] Secondly, by fixing a horizontal pushing cylinder 19 for pushing the lower movable vulcanization plate 18 on the side away from the discharge end of the lower pressing platform 14, after the rubber component is vulcanized, the horizontal pushing cylinder 19 can be used to push the lower movable vulcanization plate 18 to slide along the track beam 17 to output the vulcanized rubber component.

[0029] It should be noted that, in this embodiment, both the upper vulcanizing plate 16 and the lower movable vulcanizing plate 18 are electrically heated vulcanizing plates; of course, in some other embodiments, a multi-stage steam vulcanizing plate may be selected according to specific production requirements.

[0030] See attached Figure 2 and Figure 4 The vertical pushing assembly 2 includes a vertical support 21 arranged vertically, a movable support plate 22 slidably mounted on the vertical support 21, and a fixed support 23 fixedly mounted on the discharge end of the track beam 17. Vertical support rods 24 are vertically fixedly mounted on both sides of the movable support plate 22. The vertical support rods 24 are slidably penetrated on the fixed support 23, and a top support plate 25 is fixedly mounted on the top of the vertical support rod 24. At the same time, a vertical pushing cylinder 26 is fixedly mounted on the bottom surface of the vertical support 21, and then the power output end of the vertical pushing cylinder 26 passes through the vertical support 21 and is fixedly mounted on the bottom surface of the movable support plate 22. The vertical pushing cylinder 26 can be used to push the movable support plate 22 to slide vertically along the vertical track rod, thereby driving the vertical support rods 24 and the top support plate 25 vertically fixed thereon to perform vertical lifting and lowering movements along the track holes on the fixed support 23.

[0031] See attached Figure 5-Figure 9An inner support 31 is embedded in the adsorption conveyor belt 3 to support it. The four corners of the inner support 31 are rotatably installed with driving rollers 32 for driving the adsorption conveyor belt 3 to reciprocate the fluororubber. Through holes are provided on the adsorption conveyor belt 3 and the inner support 31. At the same time, side supports 33 are symmetrically provided at both ends of the inner support 31. A bronchial tube 34 is integrally formed on the side support 33, and a connecting port 35 is installed in communication with the bronchial tube 34. Support tubes 37 are integrally formed on both sides of the inner support 31, and the support tubes 37 are fixedly inserted into the bronchial tube 34. At the same time, a sealing pad 38 is embedded in the interface to ensure the suction seal and avoid air leakage. After connecting the connecting port 35 to a vacuum pump, the vacuum pump can be used to extract the air inside the inner support 31 and on the surface of the adsorption conveyor belt 3 to form a negative pressure, so as to adsorb the rubber component when it contacts it.

[0032] Secondly, since through holes are also provided at the arc-shaped portions at both ends of the inner support 31, when the adsorption conveyor belt 3 adsorbs the rubber component and bends and transmits through the arc-shaped portions at both ends of the inner support 31, the rubber component can also tightly adsorb it, so that it bends synchronously with the adsorption conveyor belt 3 to maintain transmission synchronization.

[0033] Of course, in order to ensure the stability of the adsorption of the rubber parts, the density of the through holes on the surface of the adsorption conveyor belt 3 is much greater than the density of the through holes on the surface of the inner support 31. At the same time, the diameter of the through holes on the surface of the adsorption conveyor belt 3 is much smaller than the diameter of the through holes on the surface of the inner support 31. In this way, the negative pressure suction can be continuously maintained during the rotation transmission process.

[0034] Furthermore, a first servo motor 39 for driving the driving roller 32 is fixedly installed in the inner support 31 near one end of the driving roller 32. The first servo motor 39 can be used to drive the adsorption conveyor belt 3 to rotate forward or reverse around the inner support 31 to transport the rubber parts adsorbed on its surface.

[0035] It should be noted that by fixing the side support 33 on the top support plate 25, the adsorption conveyor belt 3 can be pushed up and down vertically by the vertical pushing cylinder 26, and then the movable vulcanization plate 18 can slide along the track beam 17 under the push of the horizontal pushing cylinder 19 to output the vulcanized rubber parts. Then, the adsorption conveyor belt 3 can transport the adsorbed rubber parts downward and transport them upward to cooperate with the pressure measuring platform 4 for detection.

[0036] See attached Figure 4 as well as Figure 10-11The bottom array of the pressure measuring platform 4 is rotatably connected to pressure rollers 41, and they are connected to each other through gear transmission. At the same time, a driving motor 42 is fixedly installed on one side of the pressure measuring platform 4. By directly connecting the power output end of the driving motor 42 with one of the pressure rollers 41, the driving motor 42 can be used to synchronously drive all the pressure rollers 41 to rotate, and the rotation direction is opposite to the transmission direction of the adsorption conveyor belt 3. After the adsorption conveyor belt 3 adsorbs the rubber component, it can be transferred and flipped to the opposite side of the pressure measuring platform 4, and then it is pushed vertically upward by the vertical pushing cylinder 26. The two cooperate with each other to use the pressure roller 41 to extrude the rubber component, and a pressure sensor (not shown in the figure) is arranged in the pressure measuring platform 4, which can continuously control the pressure to be constant during the extrusion process, and separate the two after a certain period of extrusion.

[0037] Secondly, by fixing an industrial camera 36 on the top surface of the side support 33 and facing the adsorption conveyor belt 3 and parallel to it, the industrial camera 36 can be used to observe the recovery state of the rubber accessory and record the recovery time, and transmit it to the judgment system to determine whether the rubber component is completely vulcanized.

[0038] Among them, if it quickly recovers to its original shape after extrusion (rebound time ≤ 1 second) and the residual deformation is less than 5%, it means that the rubber component is fully vulcanized and needs to be output through the adsorption conveyor belt 3.

[0039] Among them, slow rebound (>3 seconds) and residual deformation >10% indicate low cross-linking density or the presence of unreacted sulfur, which means insufficient vulcanization. At this time, the rubber part needs to be treated twice before vulcanization.

[0040] See attached Figure 10-12 In order to perform secondary vulcanization on the rubber parts that are under-vulcanized, a grinding assembly 5 is also provided in this embodiment, which includes a top support 51 installed on the top surface of the pressure measuring platform 4, a bending bracket 52 integrally formed with the top support 51, and a transmission roller 53 rotatably installed on the bending bracket 52. A grinding belt 55 is wound between the transmission rollers 53, and a second servo motor 54 is fixedly installed on the bending bracket 52, and the power output end is connected to one of the transmission rollers 53 through a synchronous wheel set. The second servo motor 54 can be used to drive the grinding belt 55 to rotate around the transmission roller 53, and the rotation direction is opposite to the transmission direction of the adsorption transmission belt 3.

[0041] Furthermore, when the vertical pushing cylinder 26 pushes the adsorption conveyor belt 3 to adsorb the rubber component to contact the grinding belt 55, the colloid produced on the surface of the rubber component due to vulcanization can be removed to facilitate its secondary vulcanization.

[0042] It should be noted that the bending bracket 52 is bent in a √ shape, so that a triangular space can be formed at its bending position, which can facilitate the installation of the second servo motor 54. At the same time, the second servo motor 54 can be used to directly drive the transmission roller 53 at the center of the bend, so that the grinding belt 55 is in closer contact with the rubber component, thereby ensuring the grinding efficiency and effect.

[0043] Secondly, a mounting groove 56 is provided at the connection between the bent bracket 52 and the top support 51, and a card interface 57 is provided in the mounting groove 56. By embedding the collecting groove 58 in the mounting groove 56 and tangentially fitting the edge of the collecting groove 58 to the surface of the grinding belt 55, it can be used to scrape off the colloid. Then, a card edge 59 matching the card interface 57 is integrally formed on the collecting groove 58, and the card edge 59 can be embedded in the card interface 57 to limit the collecting groove 58. At the same time, the downward thrust of the reverse rotation of the grinding belt 55 acts synchronously on the scraping mouth of the collecting groove 58, which can not only limit the collecting groove 58 to keep it stable, but also help to scrape off the colloid.

[0044] Furthermore, an upper mounting groove 43 is provided on the top surface of the pressure measuring platform 4, and a support shaft 44 is fixedly installed inside the groove. At the same time, a support shaft sleeve 511 is integrally formed on the bottom surface of the top support 51. The support shaft sleeve 511 is rotatably connected to the support shaft 44. At the same time, a gap is formed between the top support 51 and the bottom surface of the upper mounting groove 43, and a limiting spring 510 is embedded in the gap. When the rubber component contacts the surface of the grinding belt 55, the rebound force of the spring compression or stretching can act on the grinding belt 55 through the bending bracket 52 and the top support 51, so that it is in close contact with the rubber component, thereby ensuring the glue removal effect and ensuring that the glue removal is more complete.

[0045] Of course, in some other embodiments, the grinding assembly 5 may not be provided, and the selection is made according to specific needs and also according to the different rubber parts to be processed.

[0046] After the rubber parts that need secondary vulcanization are debonded, the adsorption conveyor belt 3 is needed to transfer them to the side facing the lower movable vulcanization plate 18. At the same time, the vacuum pump stops pumping air, so that the adsorption conveyor belt 3 loses its adsorption force, and then the rubber parts are placed back on the surface of the lower movable vulcanization plate 18. After the horizontal push cylinder 19 retracts, it is placed again between the lower movable vulcanization plate 18 and the upper vulcanization plate 16 for pressurized heating and vulcanization again to ensure complete vulcanization, and then tested again.

[0047] After detecting that the rubber parts are completely vulcanized, the horizontal push cylinder 19 pulls the lower movable vulcanizing plate 18 back to reset, and the next group of rubber parts are vulcanized. At the same time, the suction conveyor belt 3 outputs the completely vulcanized rubber parts.

[0048] See attached Figure 1 as well as Figure 13-14 , in this embodiment, a cleaning box 6 is further provided. Inside the inner side of the top surface of the cleaning box 6, a guiding plate 61, a scraping knife 62 and a guiding side plate 63 are sequentially installed. The scraping knife 62 and the guiding side plate 63 are arranged at intervals, and a cutting gap is reserved between them. By arranging the scraping knife 62 obliquely, and the cutting edge is in the same plane as the inner surfaces of the guiding plate 61 and the guiding side plate 63. After detecting that the rubber part is completely vulcanized, it is transmitted downward by using the vertical pushing cylinder 26 until the bottom surface of the adsorption conveyor belt 3 is attached to the top surface of the guiding plate 61; at this time, the adsorption conveyor belt 3 gradually flips and conveys the rubber part from top to bottom. At the same time, during the flipping and conveying process, the guiding plate 61 is used to position it and gradually convey it between the scraping knife 62 and the guiding side plate 63. At this time, if there are protruding parts at the edge, they will protrude into the interval space between the guiding plate 61, the scraping knife 62 and the guiding side plate 63, and then be cut off when passing through the scraping knife 62, so as to correct the rubber part. At the same time, the redundant part will fall into the cleaning box 6 for collection, so as to be cleaned later.

[0049] Among them, the guiding plate 61 is in a shape of a reverse slash. In this way, when the rubber part gradually enters, it can be gradually guided and positioned. At the same time, the scraping knife 62 and the guiding side plate 63 appear in groups at equal intervals. There are two groups designed by the designer of this embodiment; of course, in some other embodiments, different groups can be set according to needs.

[0050] It should be noted that a plum blossom groove 65 is opened inside the inner side of the top surface of the cleaning box 6, and plum blossom keys 64 matching the plum blossom groove 65 are fixedly installed on the bottom surfaces of the guiding plate 61, the scraping knife 62 and the guiding side plate 63. The plum blossom keys 64 and the plum blossom groove 65 can be inserted into each other to fix them to each other. At the same time, the plum blossom keys 64 and the cleaning box 6 are further fixed by screws, which can ensure the stability of the connection, so that there will be no shaking during the correction of the rubber part, thus ensuring the correction accuracy.

[0051] Secondly, in some other embodiments, if there is no need to trim the rubber part, the cleaning box 6 can not be set, and it can be selected according to specific production needs; at the same time, the cleaning box 6 is detachably installed inside the discharging end of the track cross beam 17 by screws, and it can also be removed when not needed.

[0052] The working principle of the present invention is as follows: First, place the rubber part on the lower movable vulcanizing plate 18, and cooperate the lower movable vulcanizing plate 18 with the upper vulcanizing plate 16 through the hydraulic cylinder 12 to heat and press vulcanize the rubber part placed between the two. Then, use the horizontal pushing cylinder 19 to push the lower movable vulcanizing plate 18 to slide along the track cross beam 17 to output the vulcanized rubber part.

[0053] Secondly, the vertical push cylinder 26 is used to transport the adsorption conveyor belt 3 downward, and the vacuum pump is used to adsorb the rubber component and transport it upward to cooperate with the pressure measuring platform 4 for testing. After the test, it is determined whether it is completely vulcanized: If the vulcanization is insufficient, the vertical pushing cylinder 26 is used to push the adsorption conveyor belt 3 to adsorb the rubber component and bring it into contact with the grinding belt 55, so that the colloid produced by vulcanization on the surface of the rubber component can be removed. Then, the adsorption conveyor belt 3 is used to place the rubber component on the surface of the lower movable vulcanization plate 18 again. After the horizontal pushing cylinder 19 retracts, it is placed again between the lower movable vulcanization plate 18 and the upper vulcanization plate 16 for pressurization, heating and vulcanization again.

[0054] If the vulcanization is complete, the rubber component is gradually turned over and transported from top to bottom using the adsorption conveyor belt 3. During the turning and transporting process, the guide plate 61 is used to position it. The rubber component is then corrected by the scraper 62. After the correction, the vacuum pump is turned off and the rubber component is output using the adsorption conveyor belt 3.

[0055] Finally, the above situation is repeated over and over again, and the rubber parts are continuously heated and pressurized for vulcanization to ensure that the rubber parts are fully vulcanized to meet production needs.

[0056] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
