[0021] The first embodiment of the present application is:

[0022] See also Figure 1-Figure 3 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model; Figure 2 yes Figure 1 The enlarged view of point A in the middle; Figure 3 It is a structural schematic diagram of the moving component of the first embodiment of the utility model.

[0023] The utility model provides a rubber production batching weighing machine: comprising a batching tank 101 and a weighing mechanism, wherein the weighing mechanism comprises a weighing frame 102, a weighing box 103, a moving platform 104, a weighing scale 105, a weighing platform 106, a baffle 107, a moving component, a solenoid valve 116 and a controller 117, wherein the moving component comprises a moving frame 108, a moving motor 109, a convolution axis 110, two pulling chains 111, a strong spring 112, a protective shell 113 and two auxiliary parts, wherein the auxiliary parts comprise a rotating shaft 114 and two rollers 115. The above-mentioned solution solves the problem that the above prior art cannot weigh the batching, and when the production batch changes, the amount of the added batching will not change accordingly, so that the proportion of the batching changes, which will lead to poor quality of the output rubber or even scrapping.

[0024] According to the present specific embodiment, the weighing frame 102 is located on one side of the batching tank 101, the weighing box 103 is fixedly connected to the top of the weighing frame 102, and is provided with an inlet and a discharge port, the discharge port is located above the batching tank 101, the mobile platform 104 is slidably connected to the weighing box 103, and is located in the weighing box 103, and is located above the discharge port, the weighing scale 105 is fixedly connected to the top of the mobile platform 104, the weighing platform 106 is fixedly connected to the top of the weighing scale 105, the baffle 107 is slidably connected to the weighing platform 106, and is fixedly connected to the weighing box 103, and is located below the inlet, The moving component is located below the weighing box 103. When adding ingredients during rubber processing, the raw materials required for the rubber are added into the weighing box 103, and the ingredients enter the weighing box 103 from the feed port, then fall onto the weighing platform 106, and are restricted above the weighing platform 106 by the inner wall of the weighing box 103 and the baffle 107. After the weight displayed on the weighing scale 105 reaches the standard, the addition of ingredients is stopped, and the moving component is started to pull the weighing scale 105 and the weighing platform 106 backwards. The ingredients are gradually scraped away from the weighing platform 106 by the interception of the baffle 107, and fall from the weighing box 103 into the ingredient tank 101, and the addition of ingredients is completed.

[0025] The mobile frame 108 is fixedly connected to the bottom of the weighing box 103 and away from the mobile platform 104, and is used to install the mobile motor 109. The mobile motor 109 is fixedly connected to one side of the mobile frame 108 to provide power for the entire mobile assembly.

[0026] Secondly, the weighing box 103 is also provided with a moving groove, one end of the two pulling chains 111 is fixedly connected to the moving platform 104 and is located in the moving groove, the convolution axis 110 is fixedly connected to the other end of the two pulling chains 111, and is rotatably connected to the moving frame 108, and is fixedly connected to the output end of the moving motor 109. When the weighing scale 105 and the weighing platform 106 are moved, the moving motor 109 is started, the convolution axis 110 is rotated, and the two pulling chains 111 are gradually convoluted on the convolution axis 110. The moving platform 104 moves along the moving groove under the pull of the two pulling chains 111, thereby driving the weighing scale 105 and the weighing platform 106 to move.

When the moving platform 104 is reset, the moving motor 109 is started in reverse to loosen the two pulling chains 111 wound on the convolution axis 110. At the same time, under the action of the strong spring 112, the moving platform 104 is reset. At the same time, the protective shell 113 can effectively prevent impurities such as dust and particles from entering the moving component to reduce the working efficiency of the moving component.

[0028] At the same time, the rotating shaft 114 is fixedly connected to the moving platform 104, passes through the moving platform 104, and is located in the moving groove. The two rollers 115 are respectively rotatably connected to the two ends of the rotating shaft 114. When the moving platform 104 moves, the four rollers 115 respectively connected to the two ends of the rotating shaft 114 roll along the moving groove, which can effectively reduce the friction force applied to the moving platform 104 when it moves.

[0030] When adding ingredients in rubber processing, the raw materials required for rubber are added to the weighing box 103, and the solenoid valve 116 is controlled by the controller 117 to open the solenoid valve 116. The ingredients enter the weighing box 103 from the inlet through the solenoid valve 116, and then fall on the weighing platform 106, and are restricted above the weighing plate by the inner wall of the weighing box 103 and the baffle 107. After the weight displayed on the weighing scale 105 reaches the standard, the addition of ingredients is stopped, and the controller 117 is used to control the solenoid valve 116 to open the solenoid valve 116. The solenoid valve 116 is closed by the actuator 117, and the moving motor 109 is started at the same time, the convolution shaft 110 rotates, and the two pulling chains 111 are gradually convoluted on the convolution shaft 110. The moving platform 104 moves along the moving groove under the pull of the two pulling chains 111, thereby driving the weighing scale 105 and the weighing platform 106 to move, and the weighing scale 105 and the weighing platform 106 are pulled backward, and the ingredients are gradually scraped off the weighing platform under the interception of the baffle 107. 106, falls from the weighing box 103 into the ingredient tank 101, and the addition of ingredients is completed; when the moving platform 104 is reset, the moving motor 109 is started in reverse, and the two pulling chains 111 convoluted on the convolution axis 110 are loosened, and at the same time, under the action of the strong spring 112, the moving platform 104 is reset; at the same time, the protective shell 113 can effectively prevent dust, particles and other impurities from entering the moving component to reduce the working efficiency of the moving component; and when the moving platform 104 is moved, the four rollers 115 connected to the two ends of the rotating shaft 114 are respectively rotated to roll along the moving groove, which can effectively reduce the friction force of the moving platform 104 when it moves, avoiding the inability of the prior art to weigh the ingredients. When the production batch changes, the amount of ingredients added will not change accordingly, so that the proportion of ingredients changes, which will lead to poor quality of the output rubber, or even scrapped. The effect of weighing the ingredients, more accurately controlling the proportion of ingredients, and improving product quality is obtained.

The observation window 202 is fixedly connected to the weighing box 103 and is located in the installation port. When the weighing machine is working, the worker can observe the display data of the weighing scale 105 and the status of the mechanism in the weighing machine through the observation window 202.
