[0003] Compound rubber refers to rubber materials with specific properties obtained by uniformly mixing raw rubber with various compounding agents through a mixing process. One end of the compound rubber is cut into strips and placed inside the feed inlet of a vacuum degassing extruder for extrusion of the desired product. However, currently, a single rubber strip is stored through the material outlet. This can easily lead to material interruption when other operations are carried out after one rubber strip has been fed. As a result, the extruder cannot continuously extrude products, forcing the production process to be interrupted. Continuing to run the extruder will aggravate the wear of the screw and barrel, shorten the service life of the equipment, and affect the dimensional accuracy of the extruded products.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First embodiment:

[0026] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a schematic diagram of the structure of the first embodiment of the vacuum degassing extrusion device for sealing ring rubber compound provided by this utility model; Figure 2 is a schematic diagram of the structure of the rotating roller shown in Figure 1; Figure 3 is an enlarged schematic diagram of part A shown in Figure 2; and Figure 4 is an enlarged schematic diagram of part B shown in Figure 1.

[0027] A vacuum degassing extrusion device for sealing ring rubber compound includes: an extrusion device 1, a guide trough 2, an induction device 3, and a feeding device 4;

[0028] The feed chute 2 is located inside the extrusion device 1, and the sensing device 3 is located on one side inside the extrusion device 1;

[0029] The feeding device 4 includes a moving groove 41, a moving block 42, a moving wheel 43, a servo motor 44, a telescopic component 45, and multiple rotating rollers 46. The moving groove 41 is opened inside the extrusion device 1. The moving block 42 is slidably connected to the inside of the moving groove 41. The moving wheel 43 is rotatably connected to the inside of the moving block 42. The servo motor 44 is located on one side of the moving block 42. The telescopic component 45 is located on one side of the moving block 42. The multiple rotating rollers 46 are all rotatably connected to the inside of the extrusion device 1, and the multiple rotating rollers 46 are in pairs to clamp the two sections of mixed rubber.

[0030] The feed chute 2 is used to guide the compound conveyed by the rotating roller 46 into the interior of the extrusion unit 1.

[0031] Each of the two sets of rotating rollers 46 is equipped with a sensing device 3 on one side. The sensing device 3 is an infrared sensor used to check the compounded rubber held by the two sets of rotating rollers 46. When the infrared sensor detects the compounded rubber held by the first set of rotating rollers 46, the infrared sensor of the second set is turned off. When the infrared sensor of the first set detects that the compounded rubber held by the first set of rotating rollers 46 has finished conveying, the telescopic component 45 and the infrared sensor of the second set are automatically activated. At this time, the infrared sensor above the first set is turned off. When the compounded rubber held by the second set of rotating rollers 46 has finished conveying, the telescopic component 45 is activated again to retract. At this time, the infrared sensor of the first set is turned on and the infrared sensor of the second set is turned off. This process is repeated to make the moving wheel 43 switch between the two sets of rotating rollers 46.

[0032] The servo motor 44 is fixedly mounted on one side of the moving block 42, and its output end is connected to the inside of the moving wheel 43 via a coupling. The servo motor 44 is used to start the moving wheel 43 to rotate to one side. The surface of the moving wheel 43 contacts the surface of the rotating roller 46, so that after the servo motor 44 is started, it drives the moving wheel 43 to rotate to one side, thereby driving the rotating roller 46 to rotate to one side.

[0033] The telescopic component 45 includes an electric push rod, which is fixedly mounted on the surface of the extrusion device 1, and its output end is fixedly mounted on one side of the moving block 42. The telescopic component 45 is a cylinder or hydraulic rod, and is installed in the same manner as the electric push rod, thereby facilitating the movement of the moving block 42 to one side.

[0034] The working principle of this first embodiment is as follows:

[0035] In use, the servo motor 44 is started, which drives the moving wheel 43 to rotate to one side, thereby driving the rotating roller 46 to rotate to one side. This causes one end of the compound material placed between the two rotating rollers 46 to move to one side and enter the interior of the extrusion device 1 through the guide trough 2.

[0036] When the sensing device 3 detects that there is no mixed rubber material under the first set of rotating rollers 46, it pushes the moving block 42 to move to one side inside the moving groove 41 through the telescopic member 45, thereby driving the moving wheel 43 to move to the bottom of the next set of rotating rollers 46. Then, the servo motor 44 drives the moving wheel 43 to rotate to one side, so that the rotating roller 46 drives the mixed rubber material to move to one side for feeding.

[0037] In this first embodiment, the sensing device 3 causes the moving wheel 43 of the feeding device 4 to switch between multiple rotating rollers 46, so that after one batch of compound rubber is fed, it automatically switches to the rotating roller 46 under which the next batch of compound rubber is installed for automatic feeding, thus preventing the phenomenon of material interruption.

[0038] Second embodiment:

[0039] Referring to Figures 5 and 6, based on the vacuum degassing extrusion apparatus for sealing ring rubber compound provided in the first embodiment of this application, the second embodiment of this application proposes another vacuum degassing extrusion apparatus for sealing ring rubber compound. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0040] Specifically, the difference in the vacuum degassing extrusion device for sealing ring rubber compound provided in the second embodiment of this application is that the vacuum degassing extrusion device for sealing ring rubber compound has an adjustment device 5 inside the extrusion device 1. The adjustment device 5 includes two adjustment plates 51, two threaded rods 52 and two support plates 53. The two adjustment plates 51 are slidably connected to the inside of the extrusion device 1. One end of each of the two threaded rods 52 is rotatably connected to the top of the adjustment plate 51. The two support plates 53 are threadedly connected to the surface of the threaded rods 52.

[0041] Both support plates 53 are fixedly connected to the surface of the extrusion device 1. Both support plates 53 have threaded holes that are adapted to the threaded rods 52. The two threaded rods 52 are respectively threaded into the two threaded holes, so that when the threaded rods 52 are rotated to one side, the threaded rods 52 move upward inside the support plates 53.

[0042] A rotating handle is fixedly connected to one end of the threaded rod 52. The rotating handle is used to facilitate rotating the threaded rod 52 to one side.

[0043] The extrusion device 1 is equipped with a moving device 6. The moving device 6 includes two connecting blocks 61 and a mounting plate 62. One side of the two connecting blocks 61 is fixedly connected to one side of the two adjusting plates 51, and one side of the mounting plate 62 is fixedly connected to one side of the connecting blocks 61.

[0044] Two sensors 3 are fixedly installed at the bottom of the mounting plate 62, which are used to adjust the position of the two sensors 3 while adjusting the position of the adjustment plate 51.

[0045] The extrusion device 1 is provided with a sliding component 7. The sliding component 7 includes four sliding grooves 71 and four sliding blocks 72. The four sliding grooves 71 are all opened inside the extrusion device 1, and the multiple sliding blocks 72 are respectively slidably connected to the inside of the four sliding grooves 71.

[0046] One side of each of the four sliding blocks 72 is fixedly connected to both ends of the two adjusting plates 51.

[0047] The two ends of the two rotating rollers 46 are respectively rotatably connected to one side of the four sliding blocks 72, which are used to adjust the height of the two rotating rollers 46 through the threaded rod 52 and the adjusting plate 51, thereby facilitating the adjustment of the spacing between the multiple rotating rollers 46.

[0048] In this second embodiment, when feeding is required, the threaded rod 52 is rotated to one side, thereby moving upward inside the support plate 53. This causes the adjusting plate 51 to drive the two sliding blocks 72 to move upward inside the two sliding grooves 71, thereby driving the rotating roller 46 to move upward to the appropriate position.

[0049] After the rubber compound is placed between the two rotating rollers 46, the threaded rod 52 is rotated to one side, causing the adjusting plate 51 to move the two sliding blocks 72, thereby moving the rotating rollers 46 downwards to contact the surface of the rubber compound and limiting the position of the rubber compound.

[0050] In this second embodiment, the adjustment device 5, together with the moving device 6 and the sliding component 7, adjusts the distance between the two rotating rollers 46 in the same group, thereby allowing for the replacement of the rubber compound while facilitating the feeding of the rubber compound.

[0051] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
