Description

Technical Field

[0001] The utility model relates to the technical field of rubber forming, in particular to a preliminary refining device for vulcanized rubber forming blanks. Background Art

[0002] Rubber production mainly includes six basic processes: plasticizing, mixing, calendering, extrusion, molding, and vulcanization. Rubber plasticizing refers to the process of softening rubber into a uniform material with a certain plasticity by means of heat or mechanical work. The plasticity of the raw rubber is homogenized through preliminary plasticizing so that a rubber compound of uniform quality can be produced.

[0003] During the initial refining of existing rubber, it needs to be heated in a heating furnace to melt the rubber stock into a plastic liquid. However, after the existing rubber heating furnace completes heating of the rubber stock, the liquid rubber material needs to be output through a pipe for shaping. However, the outflow speed of the rubber material is limited by the pipe, which causes part of the rubber material to solidify before shaping. Utility Model Content

[0004] The purpose of the utility model is to provide a preliminary refining device for vulcanized rubber forming blanks to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a preliminary refining device for vulcanized rubber forming blanks, comprising a U-shaped seat, a refining assembly being provided at the upper end of the U-shaped seat, and a driving assembly being provided at one end of the refining assembly;

[0006] The refining component includes two jacks, which are symmetrically arranged on the side walls at both ends of the U-shaped seat. The interior of the two jacks is rotatably connected to a rotating shaft, and one end of the two rotating shafts is fixedly connected to a circular plate. The two circular plates are fixedly sleeved on the inner wall of the same rotating drum, and a feed port is provided on the outer wall of the rotating drum. Two annular grooves are symmetrically arranged on the outer wall of the rotating drum, and sealing rings are clamped in the two annular grooves. The outer walls of the two sealing rings are fixedly connected to the same sleeve, and the outer wall of the sleeve is provided with a discharge port.

[0007] Preferably, the drive assembly includes a fixed plate, which is fixedly connected to one side wall of the U-shaped seat, and a motor is fixedly connected to the lower surface of the fixed plate. The output end of the motor is fixedly connected to a driving gear, and the driving gear is meshed with a transmission gear, and the transmission gear is fixedly connected to one end of a rotating shaft.

[0008] Preferably, a hopper is fixedly connected to the upper surface of the U-shaped seat, and the hopper is located directly below the rotating drum.

[0009] Preferably, the feed port and the discharge port are arranged correspondingly, and the feed port and the discharge port are the same in size.

[0010] Preferably, the length of the hopper is longer than the length of the feed port.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the opening of the feed port is blocked by rotating the sleeve, and then the rotating drum is heated to melt the rubber blank. After the initial refining is completed, the rotating drum is controlled to rotate so that the feed port corresponds to the hopper, and then the discharge port on the rotating sleeve is matched with the feed port again, so that the molten rubber material flows out from the feed port, and the rubber material is quickly flowed out through the opening by gravity, and then the rubber material is guided into the mold through the hopper for shaping, thereby preventing the rubber material from quickly solidifying due to heat reduction during the transportation process.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: a preliminary refining device for vulcanized rubber forming blanks, comprising a U-shaped seat 1, a refining component 2 is provided at the upper end of the U-shaped seat 1, and a driving component 3 is provided at one end of the refining component 2;

[0020] The refining component 2 includes two jacks 21, which are symmetrically arranged on the side walls at both ends of the U-shaped seat 1. The interior of the two jacks 21 is rotatably connected to a rotating shaft 22, and one end of the two rotating shafts 22 is fixedly connected to a circular plate 23. The two circular plates 23 are fixedly sleeved on the inner wall of the same rotating drum 24. A feed port 25 is provided on the outer wall of the rotating drum 24, and two annular grooves 26 are symmetrically provided on the outer wall of the rotating drum 24. A sealing ring 27 is clamped in the two annular grooves 26. The outer walls of the two sealing rings 27 are fixedly connected to the same sleeve 28, and the outer wall of the sleeve 28 is provided with a discharge port 29. By providing a rotatable rotating drum 24 to heat the rubber billet, the billet can be directly poured out after being heated and melted, eliminating the pipeline transportation step, greatly accelerating the transportation speed of the rubber material, and preventing the rubber material from solidifying during the transportation process.

[0021] The driving assembly 3 includes a fixing plate 31, which is fixedly connected to one side wall of the U-shaped seat 1. A motor 32 is fixedly connected to the lower surface of the fixing plate 31. The output end of the motor 32 is fixedly connected to a driving gear 33. The driving gear 33 is engaged with a transmission gear 34. The transmission gear 34 is fixedly connected to one end of a rotating shaft 22. The driving gear 33 is driven to rotate by the motor 32, and the driving gear 33 drives the transmission gear 34 to rotate. When the transmission gear 34 rotates, it drives the rotating shaft 22 to rotate.

[0022] A hopper 210 is fixedly connected to the upper surface of the U-shaped seat 1. The hopper 210 is located directly below the rotating drum 24. The heated rubber material is received through the hopper 210 and guided to flow into the mold for shaping.

[0023] The feed port 25 and the discharge port 29 are correspondingly arranged and have the same size, so that the feed port 25 and the discharge port 29 can rotate correspondingly, making it convenient to take and put the rubber material in the two rotating drums 24.

[0024] The length of the hopper 210 is longer than that of the feed port 25 , thereby preventing the rubber material in the drum 24 from spilling out.

[0025] Specifically, when using the utility model, first, the motor 32 drives the driving gear 33 to rotate, the driving gear 33 drives the transmission gear 34 to rotate, and when the transmission gear 34 rotates, it drives the rotating shaft 22 to rotate, and when the rotating shaft 22 rotates, it drives the circular plate 23 to rotate, and when the circular plate 23 rotates, it drives the rotating drum 24 to rotate, so that the feed port 25 on the rotating drum 24 faces the upper end, and then the sleeve 28 is rotated to drive the discharge port 29 to correspond to the feed port 25, and the rubber blank is placed in the interior of the rotating drum 24 through the feed port 25, and then the sleeve is rotated. The cylinder 28 blocks the opening of the feed port 25, and then heats the rotating drum 24 to melt the rubber blank. After the initial refining is completed, the rotating drum 24 is controlled to rotate so that the feed port 25 corresponds to the hopper 210, and then the discharge port 29 on the sleeve 28 is rotated to correspond to the feed port 25 again, so that the molten rubber material flows out from the feed port 25. The rubber material flows out quickly through the opening due to gravity, and then is guided into the mold through the hopper 210 to be shaped, to prevent the rubber material from quickly solidifying due to heat reduction during the transportation process.
