[0002] Internal mixer is a closed mixer, which is mainly used for mixing plastics or rubber, as well as asphalt, felt and synthetic resin. There is a feed inlet at the top of the internal mixer, and the bottom is the outlet for the viscous mass after mixing. There are two main ways to add materials to the internal mixer. One is the automatic feeding method equipped with an automatic weighing system, which is mainly used for large internal mixers; the other is the manual feeding method, which is widely used in small and medium-sized internal mixers.
[0003] Internal mixers with manual feeding are usually equipped with storage devices such as hoppers in their upper space (upper factory building). Workers add a batch of materials into the hopper in advance, and operate the electric valve at the hopper outlet to feed the internal mixer in batches during internal mixing. The problem is that workers often estimate the amount of materials added to the hopper based on experience, and there is often material left after the internal mixing is completed. If the materials for the next batch of internal mixing are changed, the excess materials need to be cleaned out, and it is troublesome to clean them directly in the hopper. This problem has yet to be solved. Summary of the invention
[0004] The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology and provide a selective discharging device for the feed port of an internal mixer, which can select whether the material enters the internal mixer or is directly discharged, thereby facilitating production.

DETAILED DESCRIPTION
[0013] In order to enable ordinary technicians in the field to more clearly understand the purpose, technical solutions and advantages of the utility model, the utility model is further explained below in conjunction with the accompanying drawings and embodiments, but the utility model is not limited to the following embodiments.
[0014] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0015] like Figure 1As shown, this embodiment provides a selective discharge device for a feed port of an internal mixer, comprising a discharge chamber 6, a discharge branch pipe 12, a movable door 5 and a drive assembly.
[0016] The discharge chamber 6 is made of a square tube, and the material inlet 3 at the upper end of the discharge chamber 6 gradually closes and connects with the electric valve 2 of the hopper outlet 1. After the electric valve 2 is opened, the material in the hopper enters the discharge chamber 6 from the material inlet 3, and the material outlet 16 at the lower end of the discharge chamber 6 gradually closes and connects with the feed port 11 on the internal mixer. The right side wall (or the left side wall) of the discharge chamber 6 is provided with a rectangular opening to form a branch outlet 15 for the material.
[0017] The movable door 5 is arranged in the inner cavity of the discharge chamber 6 through the rotating shaft 10. The rotating shaft 10 drives the movable door 5 to swing under the drive of the driving assembly. In this embodiment, the movable door 5 is rectangular, and its bottom is fixed on the rotating shaft 10. The rotating shaft 10 is arranged in the front-to-back direction and is parallel to the bottom edge of the branch outlet 15. The edges around the movable door 5 are flush with or exceed the edges around the branch outlet 15. With such a structure, when the movable door 5 swings to the side where the movable door 5 is located to the end of the stroke ( Figure 1 The movable door 5 is in the erected state in the middle), the movable door 5 blocks the branch outlet 15 on the side of the discharge chamber 6, and the material cannot be discharged from the branch outlet 15. At this time, the material inlet 3 at the upper end of the discharge chamber 6 is connected with the material outlet 16 at the lower end, and the material from the hopper can be sent to the feed port 11 on the internal mixer. The front edge of the movable door 5 is in clearance with the front inner wall of the discharge chamber 6, and the rear edge is in clearance with the rear inner wall of the discharge chamber 6. The length of the movable door 5 in the left and right directions is greater than the distance between the left and right inner walls of the discharge chamber 6. Through such a structure, when the movable door 5 swings to the left and away from the movable door 5, the material outlet 16 at the lower end of the discharge chamber 6 will be blocked, and the material cannot enter the feed port 11 of the internal mixer. At this time, the material inlet 3 at the upper end of the discharge chamber 6 is connected with the discharge branch pipe 12 through the branch outlet 15, and the material from the hopper can be sent to the branch outlet 15. It should be noted that, since the length of the movable door 5 is greater than the distance between the left and right inner walls of the discharge chamber 6, the movable door 5 will be blocked by the left inner wall of the discharge chamber 6 at the end of the stroke, forming a structure that gradually tilts from left to right ( Figure 1 The movable door 5 is in a tilted state to facilitate guiding the materials into the branch outlet 15, and at the same time, the left inner wall of the discharge chamber 6 also provides support for the movable door 5 to resist the impact force of the materials.
[0018] The discharge branch pipe 12 is connected to the branch outlet 15 , and the discharge branch pipe 12 starts to slope downward from the branch outlet 15 and gradually converges into a round opening, and the round opening is connected to an extension pipe 13 (a corrugated hose can be used), and the extension pipe 13 is connected to a collection container 14 .
[0019] In this embodiment, the driving assembly includes a cylinder 4 and a swing arm 9, the cylinder 4 is fixed to the outer wall of the discharge chamber 6, one end of the rotating shaft 10 extends from the discharge chamber 6 and is fixed with a swing arm 9, and the overhanging end of the swing arm 9 is hinged to the top rod 7 of the cylinder 4 through the hinge shaft 8. It should be noted that since the overhanging end of the swing arm 9 will change in height to a certain extent during the swinging process, an adjustment slot or an adjustment hole needs to be provided at the hinge of the swing arm 9 and the top rod 7 to adapt to the change in height. The shape of the adjustment slot or the adjustment hole is conventional technology and will not be described in detail here.
[0020] The working principle of this embodiment is: during the normal production process of the internal mixer, the push rod 7 of the cylinder 4 rotates the movable door 5 to the position of blocking the branch outlet 15, and after the electric valve 2 of the hopper is opened, the material can normally enter the feed port 11 of the internal mixer through the discharge chamber 6. When it is necessary to discharge the excess material in the hopper, the push rod 7 of the cylinder 4 rotates the movable door 5 to the position of blocking the material outlet 16 at the lower end of the discharge chamber 6, and after the electric valve 2 of the hopper is opened, the material cannot enter the feed port 11 of the internal mixer, but is sent to the collection container 14 through the branch outlet 15, the discharge branch pipe 12, and the extension pipe 13 for recollection and recycling.
[0021] The above is only a preferred embodiment of the utility model. For those skilled in the art, the utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
