[0020] The following is combined with Figure 1-8 The specific implementation methods of the utility model are further described in detail.
[0021] Embodiment 1, the technical solution is that during the use of the utility model, the lifting device provided can drive the material blocking shell 7 and the push rod 12 and other components in the material blocking shell 7 to lift and lower through the connecting rod 6, and then the push rod 12 can be positioned to the corresponding height, and then the first motor 2413 can be started. Under the drive of the first motor 2413, the first reciprocating screw 9 can drive the longitudinal rod 10 to reciprocate along the longitudinal rod 8, and then the push rod 12 fixedly connected to the longitudinal rod 10 through the short rod 11 will also reciprocate accordingly, and then the push rod 12 can smooth and evenly distribute the materials in the weighing cylinder 4 during the reciprocating movement, so that the materials can fully fill the weighing cylinder 4, ensure the volume ratio, and then weigh a sufficient amount of materials. The present application has a simple structure, is easy to use, and is highly practical, and can complete the smoothing operation without manual operation of the weighed materials.
[0022] Embodiment 2. On the basis of embodiment 1, when the utility model is in use, the electronic scale 2 is installed on the weighing platform 1, and the weighing cylinder is arranged on the electronic scale 2 through the frame 3. The skin is peeled before weighing, and then the plastic additive raw material to be weighed is sent into the weighing cylinder through the upper opening of the weighing cylinder 4 for weighing. The side wall of the weighing cylinder 4 is arranged with an observation window 14 made of tempered glass, which can be used to observe the stacking situation of the material in the weighing cylinder 4 and the height of the push rod 12. When necessary, the position of the push rod 12 can be adjusted by lifting and lowering, and then the first motor 2413 is started to drive the push rod 12 to move back and forth to smooth and evenly distribute the accumulated material.
[0023] When using the lifting function, start the second motor 24 on the bracket 20 to rotate forward, and the forward rotation of the second motor 24 will drive the second screw 23 between the base plate 22 and the bracket 20 to rotate forward. The forward rotation of the second screw 23 will drive the vertical rod 25 to move downward along the vertical rod 21, and then the connecting rod 6 fixedly connected to the vertical rod 25, the material blocking shell 7 fixedly connected to the connecting rod 6, and the relevant components installed on the material blocking shell 7 including the pushing rod 12 will also move downward accordingly. Correspondingly, starting the second motor 24 in reverse will drive the above-mentioned components including the pushing rod 12 to move upward, and then the height of the pushing rod 12 can be adjusted to facilitate even distribution of the material.
[0024] After adjusting the pushing rod 12 to an appropriate height, the first motor 2413 can be started to evenly distribute the material. The first motor 2413 drives the first reciprocating screw 9 to rotate, and the first reciprocating screw 9 will drive the longitudinal movement rod 10 to move longitudinally back and forth along the longitudinal rod 8, and then the short rod 11 together with the pushing rod 12 will also move back and forth accordingly, and then the coating rod can evenly distribute the material so that the material is evenly distributed in the weighing cylinder 4, ensuring the volume ratio of the weighing cylinder 4 and being able to weigh a sufficient amount of material.
[0025] Embodiment 3, based on Embodiment 2, when weighing is completed and material needs to be discharged, the feeding motor 2419 is started, the feeding motor 2419 drives the feeding screw 17 to rotate, and the feeding screw 17 drives the material to be discharged from the discharge cylinder 15 to the discharge pipe 16 and discharged from the discharge port 18. A conveyor belt and other corresponding equipment can be arranged at the discharge port 18 to facilitate the further transportation of the material. The blocking shell 7 can prevent the material from falling on the first reciprocating screw 9 when the material is discharged into the weighing cylinder 4, so as to prevent the material from adhering to the first reciprocating screw 9 and affecting its operation. The upper end of the blocking shell 7 is an inclined structure, which is convenient for the material to slide. The vertical shift rod 25 is a cross structure.
