Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machines, in particular to a semi-automatic rubber mixing machine. Background Art

[0002] A rubber mixer is a device used to prepare various rubber products. It mainly softens the rubber raw materials by heating and mixes them together, making them sticky and able to be further formed by molds. During the rubber mixing process of the rubber mixer, there are often residual materials that fall off the mixing rollers on the rubber mixer and fall onto the bottom plate of the rubber mixer, resulting in a waste of raw materials.

[0003] The prior art method for solving the above problems is to set a material collecting box at the bottom of the rubber mixer, collect the residual materials generated during the rubber mixing process, re-introduce them into the rubber mixer at one time, and mix them with the raw materials being refined.

[0004] Although this can solve the problem of waste of residual materials, there are still the following disadvantages: after the residual materials are collected, the residual materials in the collection box need to be manually re-introduced into the rubber mixer, which not only adds a process, but also takes a long time to collect these residual materials. During this period, the residual materials that enter the collection box early are easy to cool and solidify. When these cooled residual materials re-enter the rubber mixer, they have to go through the process of heating and softening, which affects the refining time of the raw materials being refined.

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 2 to Figure 5 As shown, the semi-automatic rubber mixing machine includes a fixed frame 1. The first refining roller 21 and the second refining roller 22 in this embodiment are rotatably arranged on the fixed frame 1. The first refining roller 21 and the second refining roller 22 are on the same horizontal plane to facilitate the placement of raw materials. A limiting structure is arranged above the first refining roller 21 and the second refining roller 22 to limit the refining width. The collecting box 4 is fixedly arranged on the fixed frame 1, and the collecting box 4 is arranged below the first refining roller 21 and the second refining roller 22. The transporting structure is arranged on the fixed frame 1, and is used to transport the remaining materials in the collecting box 4 to above the first refining roller 21 and the second refining roller 22.

[0030] The sliding round rod 81 in this embodiment is fixedly arranged on the upper side of the fixed frame 1, and the limiting structure includes a first limiting plate 31 and a second limiting plate 32. The first limiting plate 31 is arranged between the first refining roller 21 and the second refining roller 22. The lower end of the first limiting plate 31 is respectively provided with a first abutting groove 311 abutting against the first refining roller 21, and a second abutting groove 312 abutting against the second refining roller 22, which are used to clamp the first limiting plate 31 and the second limiting plate 32 so that the first limiting plate 31 and the second limiting plate 32 will not rotate. The sliding sleeve 82 is fixedly arranged on the first limiting plate 31, and the sliding sleeve 82 is sleeved on the sliding round rod 81 and is slidably connected with the sliding round rod 81. The locking structure 8 is arranged between the sliding sleeve 82 and the sliding round rod 81, and is used to lock the relative position of the sliding sleeve 82 relative to the sliding round rod 81. The first limiting plate 31 and the second limiting plate 32 have the same structure. Such a design enables the width of the refined colloid to be adjusted by adjusting the positions of the first limiting plate 31 and the second limiting plate 32 on the sliding round rod 81 .

[0031] The locking structure 8 in this embodiment includes an adjusting bolt 83, a threaded hole is set at the top of the sliding sleeve 82, the adjusting bolt 83 is threadedly connected with the threaded hole, and the center of the adjusting bolt 83 points to the central axis of the sliding round rod 81. This design ensures that when the first limit plate 31 and the second limit plate 32 slide to a suitable position, the position of the first limit plate 31 and the second limit plate 32 relative to the sliding round rod 81 does not change by rotating the adjusting bolt 83, ensuring that the width of the colloid is constant during the refining process.

[0032] The material collection box 4 in this embodiment includes a material collection bottom plate 43, which is fixedly connected to the fixed frame 1. The horizontal height of the material collection bottom plate 43 close to the first refining roller 21 and the second refining roller 22 is greater than the horizontal height close to the conveying structure end, which is used to produce a height difference and facilitate the collection of residual materials. The first guide plate 41 and the second guide plate 42 are respectively fixedly arranged on both sides of the material collection bottom plate 43 to prevent the residual materials from escaping. The distance between the first guide plate 41 and the second guide plate 42 gradually decreases from the end away from the conveying structure to the end close to the conveying structure, which is used to facilitate the collection of residual materials. Such a design allows the residual materials to be concentrated toward the conveying structure under the action of their own gravity, reducing the residual materials in the material collection box 4. In this embodiment, an oscillator can be set on the material collection box 4 to reduce the adhesion of residual materials to the material collection box 4.

[0033] The transport structure in this embodiment includes a shell 5, the projection surface of the shell 5 is a cylindrical structure, a transport cavity 51 is arranged in the shell 5, the rotating shaft 9 is rotatably connected to the center of the transport cavity 51, a transport rail 91 is arranged on the outer wall of the rotating shaft 9, and the transport rail 91 is spirally distributed along the central axis of the rotating shaft 9. The feed port 52 is arranged on the side of the shell 5 close to the material collection bottom plate 43, and the discharge port 53 is arranged at the upper end of the feed port 52. Such a design enables the residual material to be transported upward from the material collection box 4 at the bottom of the fixed frame 1, helping the residual material to re-enter the first refining roller 21 and the second refining roller 22 and be re-mixed with the raw materials.

[0034] The mounting plate 61 in this embodiment is fixedly arranged on the top of the housing 5, and the cross section of the mounting plate 61 is an "L"-shaped structure. The drive motor 6 is fixedly arranged on the mounting plate 61, and the output shaft of the drive motor 6 is fixedly connected to the rotating shaft 9. Such a design enables the output shaft of the drive motor 6 to be directly connected to the rotating shaft 9, reduces the number of connected parts, and makes the connection more tightly matched.

[0035] The guide hopper 7 in this embodiment is fixedly arranged on the discharge port 53, one end of the guide hopper 7 is fixedly connected to the discharge port 53, and the other end of the guide hopper 7 is located above the second refining roller 22. The horizontal height of the end of the guide hopper 7 close to the discharge port 53 is higher than the horizontal height of the other end of the guide hopper 7, so that the residual material can slide back into the first refining roller 21 and the second refining roller 22 by relying on the height difference under the action of its own gravity. Limit baffles 71 are fixed at both ends of the guide hopper 7 to prevent the residual material from falling off.

[0036] The working process of this embodiment is as follows: when residual material is generated during the rubber refining process, the residual material is transferred into the collecting box 4 under the action of its own gravity, and the collected residual material is introduced into the feed port 52 through the slope of the bottom plate of the collecting box 4, the first guide plate 41 and the second guide plate 42. At this time, due to the rotation of the rotating shaft 9 driving the conveying rail 91 to rotate, the residual material spirally rises and flows out from the discharge port 53 to the guide hopper 7, and finally re-enters the first refining roller 21 and the second refining roller 22 through the guide hopper 7 to be mixed with the raw materials and refined again.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
