Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber product forming, in particular to an energy-saving rubber product forming device and method. BACKGROUND

[0002] Traditional rubber product production mainly relies on new rubber resources, while rubber tree planting cycle is long, and natural rubber yield is limited, leading to the increasingly scarce rubber resources. In addition, the production process of new rubber needs to consume a large amount of energy and chemicals, causing great pressure on the environment, so that the recycling of waste rubber can reduce the demand for new rubber, save rubber resources, and alleviate the problem of resource shortage. In the traditional rubber product production process, the uniformity of rubber and additives cannot be guaranteed, leading to unstable product quality. In addition, rubber is easy to produce bubbles during heating, affecting product performance.

[0003] A large number of rubber product forming and corresponding devices are disclosed in the prior art. For example, a vertical self-pressurizing temperature rising regenerated rubber device is disclosed in Chinese Patent No. CN105949502A. The device comprises a conical main shaft, a main shaft sleeve, a feed inlet, an internal temperature control cooling zone of the main shaft sleeve, a material distribution and pulling piece, a rubber material processor, a rubber material cooling zone, a discharge outlet, and a driving device. The conical body of the conical main shaft is provided with a spiral groove from top to bottom. The inside of the main shaft sleeve is a conical cavity accommodating the conical main shaft and consistent with the outer shape of the conical main shaft. The top end of the main shaft sleeve is provided with a feed inlet. The lower end of the main shaft sleeve is horizontally outwardly protruding to form an annular table body. The conical main shaft sleeve is installed in the main shaft sleeve, and the gap between the conical main shaft and the main shaft sleeve gradually decreases from top to bottom. The internal temperature control cooling zone of the main shaft sleeve is fixed on the annular table body and is arranged around the outside of the main shaft sleeve. The material distribution and pulling piece is fixed on the top of the conical main shaft, and the lower end of the conical main shaft is connected with the upper end of the rubber material processor. The lower part of the annular table body is provided with a rubber material cooling zone around the rubber material processor.

[0004] When in use, the rubber material enters the feed inlet at the top of the main shaft. Under the action of the rotating conical main shaft, the rubber material gradually moves downward along the spiral groove. Since the conical main shaft becomes thicker from top to bottom, the gap between the main shaft sleeve and the conical main shaft gradually decreases, and the pressure and friction force borne by the rubber material also increase sharply. The intense friction continuously increases the temperature of the rubber material and the working surface, forming the high temperature and high pressure required for devulcanization.

[0005] However, the following problems exist in the process of forming rubber products by using the above-mentioned prior art: 1. Although the above-mentioned prior art can devulcanize the rubber material, the bubbles generated in the rubber material cannot be eliminated during the devulcanization process by only extrusion through the spiral groove, thereby affecting the subsequent injection molding of the rubber material. In addition, the rubber material containing bubbles is easy to cause defects in the rubber after injection molding, thereby affecting the quality of the rubber product.

[0006] 2. During the heating process of the rubber compound, multiple rolling can increase the density of the rubber compound, making it more compact and helping to improve the strength and wear resistance of the rubber compound. However, the existing technology mentioned above cannot roll the rubber compound multiple times, which can easily lead to product defects and increase the defect rate in subsequent molding processes.

[0041] Referring to Figure 5 , Figure 6 and Figure 7In order to avoid the rubber adhering to the inner wall of the mixing tank 1 and mixing unevenly, a stirring assembly 3 is provided in the embodiment. Specifically, each stirring assembly 3 includes a plurality of arc-shaped plates 31 distributed equidistantly along the outer wall of the stirring cylinder 11. The arc-shaped plates 31 are rotationally connected to the stirring cylinder 11. Two sliding grooves 32 are formed on the arc-shaped plates 31. A stirring rod 33 is slidably connected in the sliding grooves 32. Two crossbars 34 are sleeved on the outer wall of the transmission shaft 22.

An auxiliary shaft 36 is connected to the side of the arc-shaped plate 31 close to the axis of the stirring cylinder 11. An auxiliary gear 37 is sleeved on the outer wall of the auxiliary shaft 36. A plurality of tooth blocks 38 meshing with the auxiliary gear 37 are mounted on the opposite sides of the connecting ring 35. The plurality of tooth blocks 38 are distributed equidistantly along the axis of the connecting ring 35.

[0042] It should be noted that the arc-shaped plate 31 is an elastic structure capable of elastic deformation. A limiting ring is arranged between the connecting position of the arc-shaped plate 31 and the stirring cylinder 11 to limit the position of the arc-shaped plate 31, so as to avoid the melted rubber from penetrating into the gap between the connecting position of the arc-shaped plate 31 and the stirring cylinder 11. In addition, the rotation of the arc-shaped plate 31 can be avoided from being interfered.

[0043] In the specific implementation process, the transmission shaft 22 drives the crossbars 34 to rotate synchronously. The two crossbars 34 drive the connecting ring 35 and the tooth blocks 38 to rotate synchronously. The tooth blocks 38 drive the auxiliary shaft 36 to rotate through the auxiliary gear 37. The auxiliary shaft 36 drives the arc-shaped plate 31 to rotate synchronously. During this period, since the transmission shaft 22 drives the two tooth blocks 38 to rotate in the same direction, the corresponding two auxiliary shafts 36 of the two stirring assemblies 3 rotate relative to each other. The arc-shaped plate 31 drives the stirring rod 33 to rotate circumferentially along the rotation direction of the auxiliary shaft 36. Thus, after the rubber is rolled on the inner wall of the mixing tank 1 by the rolling roller 13, the stirring rod 33 twists the rubber rolled on the inner wall of the mixing tank 1, and then grabs the rubber and rolls it again in cooperation with the rolling roller 13, so as to avoid the rubber adhering to the inner wall of the mixing tank 1 and being unable to be rolled by the rolling roller 13. The rubber can be twisted and torn by the stirring rod 33 driven by the auxiliary shaft 36 rotating relative to each other, so as to enhance the mixing effect of the rubber and the sulfur powder in cooperation with the rolling roller 13. When the stirring rod 33 rotates circumferentially along the axis direction of the auxiliary shaft 36, the stirring cylinder 11 drives the arc-shaped plate 31 and the stirring rod 33 to rotate circumferentially synchronously. In the process of rolling the rubber and the sulfur powder by the rolling roller 13, the stirring rod 33 can also stir and twist the rubber and the sulfur powder, so as to greatly improve the mixing effect of the rubber and the sulfur powder.

[0045] In the specific implementation process, the arc-shaped plate 31 drives the circumferential rotation of the stirring rod 33, and the linkage rod 43 on the stirring rod 33 slides along the wave-shaped groove 42, when the linkage rod 43 slides to the lower arc groove 45 during rotation, the linkage rod 43 drives the stirring rod 33 to move to the side close to the axis of the stirring drum 11 along the lower arc groove 45, so that the rubber adhering to the outer wall of the stirring rod 33 is separated from the outer wall of the stirring rod 33, and then the rubber is continuously rolled by the rolling roller 13; when the linkage rod 43 rotates to the upper arc groove 44 during rotation, the linkage rod 43 drives the stirring rod 33 to move to the side away from the stirring drum 11 along the upper arc groove 44, and then the stirring rod 33 is inserted into the rubber pressed by the rolling roller 13, the arc-shaped plate 31 drives the stirring rod 33 to stir and twist the rubber, so that the above steps can be repeated to realize the stirring of the rubber, and the stirring effect of the rubber is further improved, and the quality of the subsequent rubber products is ensured.

[0046] It should be noted that in the embodiment, the wave-shaped grooves 42 in the inner walls of the adjacent two annular supports 41 in each stirring assembly 3 are distributed at an angle of 90 degrees, in addition, the upper arc grooves 44 and the lower arc grooves 45 both have two and are staggered, when the stirring rod 33, the auxiliary shaft 36, the auxiliary gear 37 and the annular support 41 move circumferentially to the side close to the discharge port 14, the linkage rod 43 driven by the stirring rod 33 is located in the upper arc groove 44, at this time, the stirring rod 33 is retracted into the annular support 41.

[0048] In the specific implementation process, after the rubber and sulfur powder are mixed, the multi-section hydraulic rod 16 is started, the multi-section hydraulic rod 16 pushes the discharge plate 15 to open, so that when the stirring rod 33 stirs the rubber and moves the rubber to the side close to the discharge port 14, the stirring rod 33 enters the inside of the stirring cylinder 11 along the sliding groove 32 under the action of the upper arc groove 44, the rubber falls from the discharge port 14 to the upper end of the transmission belt 21 after losing the winding of the stirring rod 33, the transmission shaft 22 drives the transmission shaft 51 to rotate through the belt drive, the transmission shaft 51 drives the transmission belt 21 to rotate, and the transmission belt 21 drives the rubber to move to the side close to the pressing roller 55; the connecting sleeve 23 drives the adjusting shaft 54 to rotate through the belt drive in the rotating process, and the adjusting shaft 54 drives the pressing roller 55 to rotate, so that when the rubber moves to the lower side of the pressing roller 55 along with the transmission belt 21, the pressing roller 55 presses the rubber to make the rubber be extruded into a rubber plate, and then the rubber plate continues to move along the transmission belt 21, so that the rubber is pressed into a rubber plate.

[0049] Further, by moving the adjusting shaft 54 out of the adjustment groove 53 and moving to the adjustment groove 53 at different heights along the sliding groove 32, the distance between the pressing roller 55 and the transmission belt 21 changes, so that when the rubber is pressed by the pressing roller 55, the thickness of the produced rubber plate changes correspondingly, so that the production of rubber plates with different thicknesses is realized, and the application range is greatly improved.

[0050] It should be noted that the transmission belt 21 used in the embodiment is made of high-temperature resistant material, so that the rubber can be pressed by the pressing roller 55 without causing adverse effects.

[0051] Further, the application also provides an energy-saving rubber product forming method, comprising the following steps: S1, rubber rolling: opening the sealing plate 18, rotating the sealing plate 18 along the hinge with the mixing tank 1, then putting the waste rubber and sulfur powder into the mixing tank 1 from the inlet 17, retracting the multi-section hydraulic rod 16 and driving the discharge plate 15 to close, so that the mixing tank 1 is sealed, heating the waste rubber by the heating wire to melt the waste rubber, facilitating the mixing of the rubber and sulfur powder; starting the driving motor 24, the output shaft of the driving motor 24 drives the transmission shaft 22 to rotate, the transmission shaft 22 drives the transmission gear 26 to rotate, the transmission gear 26 drives the linkage gear 27 and the linkage shaft 25 to rotate in opposite directions, the linkage shaft 25 drives the connecting sleeve ring 23 to rotate through belt drive, the connecting sleeve ring 23 drives the stirring cylinder 11 to rotate synchronously, so that the stirring cylinder 11 drives the rolling roller 13 to roll the rubber, and the repeated rolling of the rubber and sulfur powder can make them tear and mix repeatedly, so that the rubber and sulfur powder are fully and uniformly mixed, and the mixing effect between the rubber and sulfur powder is improved.

[0052] S2, rubber stirring: the transmission shaft 22 drives the cross 34 to rotate synchronously, the two crosses 34 drive the connecting ring 35 and the tooth block 38 to rotate synchronously, the tooth block 38 drives the auxiliary shaft 36 to rotate through the auxiliary gear 37, and the auxiliary shaft 36 drives the arc-shaped plate 31 to rotate synchronously, during which, since the transmission shaft 22 drives the two tooth blocks 38 to rotate in the same direction, the corresponding two auxiliary shafts 36 in the two stirring assemblies 3 rotate relative to each other, the arc-shaped plate 31 drives the stirring rod 33 to rotate circumferentially along the rotation direction of the auxiliary shaft 36, so that after the rubber is rolled in the inner wall of the mixing tank 1 by the rolling roller 13, the stirring rod 33 twists the rubber rolled in the inner wall of the mixing tank 1, grabs it and cooperates with the rolling roller 13 to roll it again, avoiding that the rubber adheres to the inner wall of the mixing tank 1 and cannot be rolled and mixed by the rolling roller 13, and the stirring rod 33 driven by the opposite rotating auxiliary shaft 36 can improve the twisting and tearing strength of the rubber, thereby cooperating with the rolling roller 13 to enhance the mixing effect of the rubber and sulfur powder; when the stirring rod 33 rotates circumferentially along the axis direction of the auxiliary shaft 36, the stirring cylinder 11 drives the arc-shaped plate 31 and the stirring rod 33 to rotate synchronously, and in the process of rolling the rubber and sulfur powder by the rolling roller 13, the stirring rod 33 can also stir and twist the rubber and sulfur powder, so that the mixing effect of the rubber and sulfur powder is greatly improved.

[0053] S3, complete stirring: the arc plate 31 drives the stirring rod 33 to rotate circumferentially, and the linkage rod 43 on the stirring rod 33 slides along the wave-shaped groove 42. When the linkage rod 43 slides along the downward arc groove 45 during rotation, the linkage rod 43 drives the stirring rod 33 to move along the downward arc groove 45 to the side close to the axis of the stirring cylinder 11, so that the rubber attached to the outer wall of the stirring rod 33 is separated from the outer wall of the stirring rod 33, and then the rubber is further rolled by the rolling shaft 13. When the linkage rod 43 rotates along the upward arc groove 44, the linkage rod 43 drives the stirring rod 33 to move along the upward arc groove 44 away from the stirring cylinder 11, and then the stirring rod 33 is inserted into the rubber pressed by the rolling shaft 13. The arc plate 31 drives the stirring rod 33 to stir and twist the rubber, so that the above steps can be repeated to realize the stirring of the rubber.

[0054] S4, rubber forming: after the rubber and sulfur powder are stirred and mixed well, the multi-section hydraulic rod 16 is started, and the extension end of the multi-section hydraulic rod 16 pushes the discharge plate 15 to open, so that when the stirring rod 33 stirs the rubber and moves the rubber to the side close to the discharge port 14, the stirring rod 33 enters the inside of the stirring cylinder 11 along the sliding groove 32 under the action of the upward arc groove 44. The rubber falls from the discharge port 14 to the upper end of the conveyor belt 21 after losing the winding of the stirring rod 33, the transmission shaft 22 drives the transmission shaft 51 to rotate through belt transmission, the transmission shaft 51 drives the conveyor belt 21 to rotate, and the conveyor belt 21 drives the rubber to move to the side close to the pressing roller 55. The connecting sleeve 23 drives the adjusting shaft 54 to rotate during rotation, and the adjusting shaft 54 drives the pressing roller 55 to rotate, so that when the rubber moves to the lower side of the pressing roller 55 with the conveyor belt 21, the pressing roller 55 presses the rubber to make the rubber be extruded into a rubber plate, and then the rubber plate continues to move along the conveyor belt 21, so as to realize the pressing of the rubber into a rubber plate.

[0055] Further, by moving the adjusting shaft 54 out of the adjusting groove 53 and moving it to the adjusting groove 53 at different heights along the sliding groove 32, the distance between the pressing roller 55 and the conveyor belt 21 changes, so that when the pressing roller 55 presses the rubber, the thickness of the produced rubber plate changes correspondingly, so as to realize the production of rubber plates with different thicknesses, greatly improving the application range.

[0056] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
