DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in 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 in 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.

[0022] Embodiment 1:

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a quantitative batching device for rubber latex raw materials, including a frame 1, a lower hopper 2 is fixed on the frame 1, a circular plate 3 is arranged above the lower hopper 2, a cylinder for driving the circular plate 3 to move up and down is arranged on the top of the frame 1, a circular ring 4 is fixed to the bottom of the circular plate 3 through a connecting rod, a circular plate 2 41 is also fixed to the bottom of the circular plate 3 through a connecting rod, a scale line 5 is arranged on the outer surface of the lower hopper 2, a blowing mechanism 6 for blowing air toward the inner wall of the lower hopper 2 is arranged on the frame 1, and an auxiliary mechanism 7 for driving the blowing mechanism 6 to rotate is installed on the circular ring 4.

[0024] according to Figure 1-Figure 4 It can be seen that the blowing mechanism 6 includes a gear circular housing 61 arranged below the ring 4 , the bottom of the gear circular housing 61 is connected to a nozzle 62 , and the top of the nozzle 62 is connected to an air inlet pipe 63 .

[0025] according to Figure 1-Figure 4 It can be seen that a gap is left between the circular ring 4 and the second circular plate 41, and the air inlet pipe 63 slides in the gap.

[0026] according to Figure 1-Figure 4 It can be seen that the blowing mechanism 6 further includes a fan 64 fixed on the top of the frame 1 , an air outlet end of the fan 64 is connected to a hose 65 , and the other end of the hose 65 is connected to the air inlet pipe 63 .

[0027] In the prior art, when the raw materials are unloaded, part of the raw materials will adhere to the inner wall of the material box, resulting in inaccurate unloading accuracy. Improvements are now made:

[0028] When in use, a mixing box for mixing raw materials is placed at the bottom of the lower hopper 2. When raw materials need to be added, the raw materials are first introduced into the lower hopper 2, and the weight of the raw materials represented by each scale line 5 is measured in advance. With this design, when the user observes that the introduced raw materials reach different scale lines 5, the weight of the introduced raw materials can be known, and quantitative feeding can be achieved. When feeding, the cylinder drives the circular plate 1 3 and the circular ring 4 to move downward, so that the circular ring 4 and the circular plate 2 41 cover the top of the frame 1, and the valve on the lower hopper 2 is opened to allow the raw materials in the lower hopper 2 to be introduced into the mixing box for mixing. After feeding, part of the raw materials will adhere to the inner wall of the lower hopper 2. At this time, the fan 64 can be started, and strong wind enters the air inlet pipe 63 through the fan 64, and then enters the gear circular housing 61 from the air inlet pipe 63, and finally is ejected from the air nozzle 62 to blow off the raw materials adhering to the inner wall of the lower hopper 2, thereby reducing the waste of raw materials and making the feeding accuracy more accurate.

[0029] The scale line 5 can also be replaced by a metering pump or a metering flow meter to achieve accurate metering.

[0030] Embodiment 2:

[0031] according to Figure 1-Figure 4 It can be seen that the auxiliary mechanism 7 includes a rotating rod 71 that rotates in the middle of the circular plate 41 through a bearing, a motor 72 is fixed to the top of the circular plate 41 for driving the rotating rod 71 to rotate, a gear plate 73 is fixed to the bottom end of the rotating rod 71, and the gear circular housing 61 is meshed and connected with the gear plate 73.

[0032] according to Figure 1-Figure 4 It can be seen that the auxiliary mechanism 7 further includes a limiting groove 74 opened on the top of the circular plate 41 , and a limiting block 75 is fixed on the top of the air inlet pipe 63 , and the limiting block 75 slides in the limiting groove 74 .

[0033] Compared with the first embodiment, further, when blowing air to the inner wall of the lower hopper 2, the motor 72 can be started to drive the rotating rod 71 and the gear plate 73 to rotate. Since the gear plate 73 and the gear circular shell 61 rotate, the nozzle 62 can be rotated for one circle, so as to blow air to different positions of the inner wall of the lower hopper 2, blow off the raw materials at different positions, avoid part of the inner wall from being blown away, and further improve the accuracy of material discharge. When the gear circular shell 61 rotates, the air inlet pipe 63 will rotate in the gap between the circular plate 2 41 and the ring 4, and will also drive the limit block 75 to rotate in the limit groove 74, thereby limiting the gear circular shell 61 and improving stability.
