[0029] See also Figure 1-7 The utility model provides a technical solution: a plastic raw material color mixing device, including a mixing tank body 3, a base support plate 2 is fixedly connected to the bottom of the mixing tank body 3, three support legs 1 are fixedly connected to the lower surface of the base support plate 2, a connecting component 4 is fixedly connected to the outer surface of the mixing tank body 3, a connecting end of the connecting component 4 away from the mixing tank body 3 is fixedly connected to an upper cover 5, the connecting component 4 can rotate to drive the upper cover 5 to open, an upper cover handle 6 is fixedly connected to the outer surface of the upper cover 5, and a control cabinet 16 is fixedly connected to the side surface of the mixing tank body 3;
[0030] A limiting device is provided above the upper cover 5;
[0031] A flashlight dual-control feeding device is provided on the top of the upper cover 5;
[0032] The hand-held dual-control feeding device includes a feeding pipe 14, which is fixedly connected to the outer surface of the upper cover 5, and a rectangular plate 11 is fixedly connected to the outer surface of the feeding pipe 14, and a second motor 12 is bolted to the upper surface of the rectangular plate 11, and the second motor 12 is a servo motor;
[0033] A feed valve 13 is fixedly connected to the pipeline interface of the feed pipe 14. The output end of the second motor 12 rotates and extends to the interior of the feed valve 13 and is connected to the rotating end of the feed valve 13. The feed valve 13 adjusts the valve through the start or stop command of the internal control system of the second motor 12, controls the feed amount, and realizes control of the feed ratio.
[0034] Further, a dial 17 is fixedly connected to the outer surface of the feed pipe 14, and a handle 15 is rotatably sleeved on the dial 17. A second hole 23 is opened on the outer surface of the transmission rod of the handle 15. The limiting device includes a spring 20, and the spring 20 is slidably sleeved inside the second hole 23 of the handle 15. A pointer 21 is fixedly connected to the outer surface of the handle 15, and the pointer 21 fits the scale on the dial 17. A hollow ejector pin 19 is slidably sleeved on the outer surface of the spring 20, and the outer end of the hollow ejector pin 19 is spherical. Due to the elastic force of the spring 20, the hollow ejector pin 19 is always in close contact with the inner wall of the dial 17.
[0035] The hollow ejector pin 19 can be telescopically moved. The inside of the scale plate 17 is provided with first holes 22 arranged equidistantly in a circular array. The hollow ejector pin 19 fits with the multiple first holes 22 of the scale plate 17. When the hollow ejector pin 19 enters the first hole 22 provided on the inner wall of the scale plate 17, a limiting effect is achieved. When the handle 15 is turned, the feeding ratio can be manually controlled under the action of the limiting device, avoiding the vibration caused by the feeding, so that the handle 15 can be freely rotated, and the accuracy of the feeding ratio is ensured;
[0036] The handle 15 is rotated to extend to the inside of the feed pipe 14. One end of the handle 15 is fixedly connected to a manually controlled feed valve 10. The manually controlled feed valve 10 is in contact with the inner wall of the feed pipe 14. By rotating the handle 15 clockwise, the rotation of the handle 15 drives the rotation of the manually controlled feed valve 10. The manually controlled feed valve 10 is a ball valve. When the handle 15 is rotated at different angles, the manually controlled feed valve 10 also rotates at corresponding angles.
[0037] The size of the feed port is changed by rotating the corresponding angle of the feed valve 10 manually. At the same time, the hollow ejector pin 19 enters the other second hole on the inner wall of the dial 17 to prevent the position adjusted by the current handle 15 from changing. At the same time, the rotation of 15 can also realize the valve adjustment of the manually controlled feed valve 10 to control the feeding amount. The dial of the dial 17 is provided with scale lines. The feeding amount can be read by the pointer 21 on the corresponding scale on the dial 17. In the normal state, the manually controlled feed valve 10 is in the normally open state. At this time, the feeding ratio is controlled by the feed valve 13.
[0038] Due to the coordinated use of the feed valve 13 and the manually controlled feed valve 10, the problem of low efficiency of the existing equipment is optimized. When problems occur in the electric control, manual control can be used in time to achieve feeding, avoiding the waste of materials inside the mixing tank due to the failure of the electric control and achieving the normal operation of the mixing tank.
[0039] Furthermore, because it is a manual and electric dual-control feeding device, when the second motor 12 fails or the feed valve 13 fails, the indicator light of the control cabinet 16 will flash, so that the staff can operate the manual control feed valve 10 in time to realize manual control of feeding, and the dial 17 is electrically connected to the control cabinet to determine the feeding amount to avoid material ratio imbalance caused by feed valve failure, resulting in material waste, and at the same time ensure the normal operation of the color mixing and stirring of the plastic raw materials.
[0040] Secondly, the upper cover 5 can be opened, because the feed pipe 14 is a hose feeder, so that the upper cover 5 can be opened and closed, so as to facilitate the cleaning and maintenance of the inside of the mixing tank, and when the equipment fails, it is also convenient for the staff to repair.
[0041] Furthermore, a discharge pipe 7 is fixedly connected to the bottom side of the stirring tank body 3, a first motor 8 is arranged at the bottom of the stirring tank body 3, a screw 9 is arranged between the stirring tank body 3 and the first motor 8, the first motor 8 is connected to the stirring tank body 3 through the screw 9, and a stirring blade 18 is fixedly connected to the output end of the first motor 8. The high-speed operation of the first motor 8 drives the stirring blade 18 to rotate, thereby achieving uniform stirring of the plastic raw material.
[0042] Furthermore, when the device is used, when adding materials to the mixing tank, the feed valve 13 adjusts the valve through the control system instructions inside the second motor 12 to control the feed ratio. When adding materials, the control system inside the second motor 12 first gives a feed instruction. When a material reaches the feed amount, the control system inside the second motor 12 gives a stop feed instruction, and the second motor 12 starts. The feed valve is driven to rotate by the rotation of the output shaft of the second motor 12, and the valve is closed. At this time, another material can be replaced;
[0043] Due to the coordinated use of the feed valve 13 and the manually controlled feed valve 10, the problem of low efficiency of the existing equipment is optimized. When problems occur in the electric control, manual control can be used in time to achieve feeding, avoiding the waste of materials inside the mixing tank due to the failure of the electric control and achieving the normal operation of the mixing tank.
[0044] Further, when the device is used, a dial 17 is fixedly connected to the outer surface of the feed tube 14, and a handle 15 is rotatably sleeved on the dial 17. A second hole 23 is provided on the outer surface of the transmission rod of the handle 15. The limiting device includes a spring 20, and the spring 20 is rotatably sleeved inside the second hole 23 provided in the handle 15. The hollow ejector 19 is slidably sleeved on the outer surface of the spring 20. Due to the elastic force of the spring 20, the hollow ejector 19 is always in close contact with the inner wall of the dial 17.
[0045] The hollow ejector pin 19 can be telescopically moved, and the inner wall of the scale plate 17 is provided with first holes 22 arranged equidistantly in a circular array. When the hollow ejector pin 19 enters the first hole 22 provided on the inner wall of the scale plate 17, a limiting effect is achieved. When the handle 15 is turned, the feeding ratio can be manually controlled under the action of the limiting device, thereby avoiding the vibration caused by the feeding, so that the handle 15 can be freely rotated.
[0046] The handle 15 extends to the inside of the feed pipe 14 and is fixedly connected with a manually controlled feed valve 10. The manually controlled feed valve is fitted with the inner wall of the feed pipe 14. By rotating the handle 15 clockwise, the rotation of the handle 15 drives the rotation of the manually controlled feed valve 10 through the output shaft. The manually controlled feed valve 10 is a ball valve. When the handle 15 is rotated at different angles, the manually controlled feed valve 10 also rotates at corresponding angles. The size of the feed port is changed by the corresponding rotation of the manually controlled feed valve 10.
[0047] The hollow ejector pin 19 enters into the first hole formed on the inner wall of the dial 17 to prevent the current position adjusted by the handle 15 from changing, thereby adjusting the valve of the manually controlled feed valve 10 and controlling the feeding amount. A pointer 21 is fixedly connected to the outer surface of the handle 15. The feeding amount can be read from the corresponding scale of the pointer 21 on the dial. In normal state, the manually controlled feed valve 10 is in a normally open state.
[0048] When using the device, when the second motor 12 fails or the feed valve 13 fails, the indicator light of the control cabinet 16 will flash so that the staff can operate the manual control feed valve 10 in time to realize manual control of feeding. The feed amount can be seen from the dial 17, and the dial 17 is electrically connected to the control cabinet, so the feed amount can be determined.
[0049] Working principle: When adding materials into the mixing tank, the feed valve 13 adjusts the valve through the control system instructions inside the second motor 12 to control the feed ratio. When adding materials, the internal control system of the second motor 12 first gives a feed instruction. When one material reaches the feed amount, the internal control system of the second motor 12 gives a stop feed instruction, and the second motor 12 starts. The feed valve is driven to rotate by the rotation of the output shaft of the second motor 12, and the valve is closed. At this time, another material can be replaced;
[0050] The outer surface of the handle 15 is provided with a limiting device, which includes a spring 20. The spring 20 is rotatably sleeved inside the second hole 23 opened in the handle 15. Due to the elastic force of the spring 20, the hollow ejector 19 is always in close contact with the inner wall of the scale plate 17. At the same time, the hollow ejector 19 can be telescopically moved. When the hollow ejector 19 enters the first hole 22 opened on the inner wall of the scale plate 17 and matched therewith, the limiting effect is achieved. When the handle 15 is rotated, the feeding ratio can be manually controlled under the action of the limiting device, thereby avoiding the vibration caused by the feeding, so that the handle 15 can be freely rotated.
[0051] The handle 15 extends to the inside of the feed pipe 14 and is fixedly connected with a manually controlled feed valve 10. The manually controlled feed valve is fitted with the inner wall of the feed pipe 14. By rotating the handle 15 clockwise, the rotation of the handle 15 drives the rotation of the manually controlled feed valve 10 through the output shaft. The manually controlled feed valve 10 is a ball valve. When the handle 15 is rotated at different angles, the manually controlled feed valve 10 also rotates at corresponding angles. The size of the feed port is changed by the corresponding rotation of the manually controlled feed valve 10.
[0052] The hollow ejector pin 19 enters the first hole 22 opened on the inner wall of the dial 17 to prevent the current position adjusted by the handle 15 from changing, so as to adjust the valve of the manually controlled feed valve 10 and control the feeding amount. The dial of the dial 17 is provided with scale lines, and the feeding amount can be read by the corresponding scale of the pointer 21 on the dial. In the normal state, the manually controlled feed valve 10 is in the normally open state;
[0053] When the second motor 12 fails or the feed valve 13 fails, the indicator light of the control cabinet 16 will flash so that the staff can operate the manual control feed valve 10 in time to realize manual control of feeding, and the feed amount can be seen from the dial 17.
[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
