Description

Technical Field

[0001] The utility model relates to the technical field of thermoplastic elastomers, in particular to a metering device for modified thermoplastic elastomer raw materials. Background Art

[0002] Thermoplastic elastomers, also known as artificial rubber or synthetic rubber, have the excellent properties of high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber, while also having the characteristics of easy processing and a wide range of processing methods of ordinary plastics.

[0003] A Chinese utility model patent with publication number CN218368401U discloses an automatic metering device for thermoplastic elastomer raw materials, which belongs to the field of thermoplastic elastomer production. The device includes a raw material bin, a discharge pipe is provided at the bottom of the raw material bin and the two are interconnected, a discharge hole is provided on the discharge pipe, and the discharge mechanism also includes a start-stop piston and a control component. The start-stop piston slides relative to the discharge pipe, and the control component is used to control the movement of the start-stop piston.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the raw materials in the above-mentioned device fall into the container by their own gravity, but the raw materials themselves are granular and fall into the container through the discharge hole. Without the help of external force, the material discharge speed is very slow and easily causes blockage, which is not conducive to improving the work efficiency of the staff. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a modified thermoplastic elastomer raw material metering device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a modified thermoplastic elastomer raw material metering device, including a support frame, the cross-section of the support frame is L-shaped, a plurality of support rods are fixedly arranged on the side walls in the vertical direction of the support frame, and a hollow silo is commonly installed on the side walls of the plurality of support rods away from the support frame, a feed port is opened on the upper surface of the silo, a feed hopper is installed in the feed port, a first motor is installed on the upper surface of the silo, the output shaft of the first motor passes through the silo and extends into the silo, a discharge hopper is installed on the bottom surface of the silo, and a stirring blade is fixedly installed on the end of the output shaft of the first motor.

[0007] Furthermore, a connecting pipe is fixedly provided on the bottom surface of the discharging hopper, a discharging pipe is connected to the side wall of the connecting pipe, a second motor is fixedly provided on the bottom surface of the connecting pipe, an output shaft of the second motor passes through the connecting pipe and extends into the connecting pipe, and a feeding screw is fixedly provided on the end of the output shaft of the second motor.

[0008] By adopting the above technical solution, when the staff needs to measure the production raw materials, the staff needs to put the production raw materials into the silo through the feed hopper. Subsequently, the staff needs to start the second motor, so that the output shaft of the second motor rotates, so that the feeding screw rotates synchronously with the output shaft of the second motor under the action of the second motor output shaft, and then the raw materials move under the action of the feeding screw, so that the raw materials are discharged from the silo through the discharge pipe. In this process, the staff can adjust the discharge speed by adjusting the speed of the second motor. In addition, in order to avoid the probability of the raw materials blocking the discharge pipe, the staff needs to start the first motor, so that the stirring blades rotate under the action of the first motor, and then the stirring blades clear the raw materials in the silo, thereby improving the work efficiency of the staff.

[0009] Furthermore, a weighing platform is fixedly provided on the upper surface of the support frame in the horizontal direction, and a collecting hopper is installed on the upper surface of the weighing platform.

[0010] By adopting the above technical solution, when the raw materials are moved to the outside of the silo through the discharge pipe, the raw materials are transferred into the collecting hopper. At this time, when the raw materials in the collecting hopper meet the standards, the staff can replace the collecting hopper.

[0011] Furthermore, a third motor is symmetrically installed on the side wall of the silo, and the output shaft of the third motor passes through the silo and extends into the silo. The ends of the output shafts of the two third motors are fixed with rotating rods, and the rotating rods are rotatably connected to the inner wall of the silo. A plurality of adjustment leaves are distributed in an array on the side wall of the rotating rods.

[0012] By adopting the above technical solution, when there are a lot of raw materials inside the silo, the staff needs to start the third motor, so that the output shaft of the third motor rotates, so that the adjusting leaf rotates under the action of the output shaft of the third motor, and then the adjusting leaf clears the raw materials in the silo, thereby increasing the flow speed of the raw materials in the silo, thereby improving the work efficiency of the staff.

[0013] Furthermore, a plurality of inclined blocks are distributed in an array on the bottom surface of the silo, and side walls of the plurality of inclined blocks abut against each other.

[0014] By adopting the above technical solution, the tilting block reduces the probability of raw materials settling on the bottom wall of the silo. In addition, the tilting block increases the flow rate of the raw materials in the silo, thereby improving the work efficiency of the staff.

[0015] Furthermore, a fixing rod is fixedly provided on two opposite inner walls of the discharge pipe, and a roller is sleeved on the side wall of the fixing rod.

[0016] By adopting the above technical solution, when the raw material moves along the discharge pipe to the outside of the discharge bin, the roller rotates, and the probability of the discharge pipe being blocked is reduced during the rotation of the roller.

[0017] Furthermore, limiting plates are symmetrically installed on the side walls of the fixing rod, and the side walls of the two limiting plates are both in contact with the roller.

[0018] By adopting the above technical solution, the limiting piece reduces the probability of the roller being offset, thereby improving the stability of the device.

[0019] Furthermore, a cover is threadedly connected to the outer wall of the discharge pipe.

[0020] By adopting the above technical solution, the cover reduces the probability of leakage of raw materials when the staff closes the device.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the staff needs to measure the production raw materials, the staff needs to put the production raw materials into the silo through the feed hopper. Afterwards, the staff needs to start the second motor to rotate the output shaft of the second motor, so that the feeding screw rotates synchronously with the output shaft of the second motor under the action of the second motor output shaft, and the raw materials move under the action of the feeding screw, so that the raw materials are discharged from the silo through the discharge pipe. In this process, the staff can adjust the discharge speed by adjusting the speed of the second motor. In addition, in order to avoid the probability of the raw materials clogging the discharge pipe, the staff needs to start the first motor to rotate the stirring blades under the action of the first motor, so that the stirring blades can clear the raw materials in the silo, thereby improving the work efficiency of the staff;

[0023] 2. In this application, when the raw materials are moved out of the silo through the discharge pipe, the raw materials are transferred into the collection hopper. At this time, when the raw materials in the collection hopper meet the standards, the staff can replace the collection hopper;

[0024] 3. In the present application, when there are a lot of raw materials inside the silo, the staff needs to start the third motor, so that the output shaft of the third motor rotates, so that the regulating leaves rotate under the action of the output shaft of the third motor, and then the regulating leaves clear the raw materials in the silo, thereby increasing the flow rate of the raw materials in the silo, thereby improving the work efficiency of the staff.

[0033] When the staff needs to measure the production raw materials, the staff needs to put the production raw materials into the silo 12 through the feed hopper 13. Subsequently, the staff needs to start the second motor 32, so that the output shaft of the second motor 32 rotates, so that the material screw 33 rotates synchronously with the output shaft of the second motor 32 under the action of the output shaft of the second motor 32, and then the raw materials move under the action of the material screw 33, so that the raw materials are discharged from the silo 12 through the discharge pipe 31. In this process, the staff can adjust the speed of the discharge by adjusting the speed of the second motor 32. In addition, in order to avoid the probability of the raw materials blocking the discharge pipe 31, the staff needs to start the first motor 14, so that the stirring blade 16 rotates under the action of the first motor 14, and then the stirring blade 16 clears the raw materials in the silo 12, thereby improving the work efficiency of the staff.

The aggregates are all in the shape of a rectangular parallelepiped with an open upper end, and the aggregate hopper 41 is installed on the upper surface of the weighing platform 4 .

A plurality of regulating leaves 52 are provided and distributed in an array on the side wall of the rotating rod 51, and are used to increase the flow speed of the raw materials in the silo 12.

[0037] When there is a large amount of raw materials inside the silo 12, the staff needs to start the third motor 5, so that the output shaft of the third motor 5 rotates, so that the regulating leaf 52 rotates under the action of the output shaft of the third motor 5, and then the regulating leaf 52 clears the raw materials in the silo 12, thereby increasing the flow speed of the raw materials in the silo 12 and improving the work efficiency of the staff.

[0043] The use principle of a modified thermoplastic elastomer raw material metering device in this embodiment is as follows: when the staff needs to meter the production raw materials, the staff needs to put the production raw materials into the silo 12 through the feed hopper 13. Subsequently, the staff needs to start the second motor 32, so that the output shaft of the second motor 32 rotates, so that the material screw 33 rotates synchronously with the output shaft of the second motor 32 under the action of the output shaft of the second motor 32, and then the raw materials move under the action of the material screw 33, so that the raw materials are discharged from the silo 12 through the discharge pipe 31. In this process, the staff can adjust the speed of the discharge by adjusting the speed of the second motor 32. In addition, in order to avoid the probability of the raw materials blocking the discharge pipe 31, the staff needs to start the first motor 14, so that the stirring blade 16 rotates under the action of the first motor 14, and then the stirring blade 16 clears the raw materials in the silo 12, thereby improving the work efficiency of the staff.
