Abstract
Description
Technical Field
[0001] This utility model relates to plastic compounding machines, and in particular to a vibrating powder-discharging device for a plastic color matching machine, belonging to the field of plastic production equipment. Background Technology
[0002] Plastic products are indispensable in people's lives, such as tableware, tables and chairs, vehicle accessories, and toys. Traditional plastic coloring methods include direct spraying, which is simple but produces poor color results and is prone to fading. Therefore, plastic color mixing machines were invented. These machines primarily mix plastic raw materials (plastic granules) and color powder in a specific ratio, stirring to coat the surface of the plastic raw materials with color powder, and then conveying the mixture to the barrel of an injection molding machine for heating and mixing. The plastic color mixing machine mainly consists of a plastic raw material feeding device, a color powder feeding device, a mixing device, and a storage device. The color powder feeding device includes a color powder base with a color powder tank on it. The bottom of the color powder tank is connected to the interior of the color powder base. The bottom of the color powder base has a powder outlet with a discharge valve. The discharge outlet is connected to the mixing chamber of the plastic color mixing machine. When powder needs to be discharged, a motor drives the discharge valve to open, allowing the color powder to fall into the mixing chamber through the discharge outlet. When pigment powder adheres to the inner wall of the can, or when too much pigment powder clogs the bottom of the can, the existing method is usually to manually tap the outer wall of the can to vibrate it and make the adhered pigment powder fall off. Manually tapping to dislodge the powder increases the labor intensity of workers and requires a dedicated worker to stand by and observe, which prevents the worker from doing other work. If the powder is not tapped, the remaining adhered powder will be wasted, and it may even cause the bottom of the can to be blocked, preventing the pigment powder from falling off and affecting the color matching of plastic raw materials. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a vibrating powder discharge device for a plastic color mixing machine that ensures the powder adhering to the inner wall of the powder tank can fall smoothly, reduces powder waste, avoids blockage at the bottom of the powder tank, and reduces the labor intensity of workers.
[0004] The technical solution of the vibrating powder dispensing device for a plastic color mixing machine of this utility model is as follows: It includes a machine body, a feeding hopper at the top of the machine body, a storage box on one side of the machine body, a mixing box above the storage box, a cover plate on the mixing box, a powder inlet on the cover plate, a color powder base on the cover plate, a powder outlet at the bottom of the color powder base, the powder outlet communicating with the powder inlet of the cover plate, a powder outlet valve at the powder outlet, the powder outlet valve being rotated by a motor, a color powder tank on the color powder base, the lower opening of the color powder tank communicating with the interior of the color powder base, a fixing plate on the side wall of the feeding hopper, a connecting rod on the fixing plate, one end of the connecting rod connected to the fixing plate, the other end of the connecting rod connected to an electric vibrator, and the other end of the electric vibrator contacting the outer wall of the color powder tank.
[0005] Furthermore, the electric vibrator includes a front housing and a rear housing, which are fixed together by fasteners and connected to a connecting rod. The outer wall of the front housing is in contact with the outer wall of the color powder tank. An installation cavity is formed inside the front and rear housings, and a vibration motor is installed in the installation cavity. The output shaft of the vibration motor is connected to an eccentric block.
[0006] Furthermore, the outer wall of the front housing is a concave arc surface.
[0007] Furthermore, a spring is fitted on the outer wall of the connecting rod, with one end of the spring in contact with the fixing plate and the other end of the spring in contact with the rear housing.
[0008] Furthermore, the cover plate is provided with two sets of color powder bases and color powder tanks, and the corresponding feed hopper sidewall is provided with two sets of fixing plates, connecting rods and electric vibrators.
[0009] The beneficial effects of the vibrating powder dispensing device for a plastic color mixing machine of this utility model are as follows: the centrifugal force generated by the high-speed rotation of the eccentric block driven by the vibrating motor causes the electric vibrator to vibrate, and the kinetic energy of the vibration is transferred to the color powder tank, causing the color powder adhering to the inner wall of the color powder tank to fall off. On the one hand, this avoids the color powder adhering to the inner wall of the color powder tank, reducing waste, and on the other hand, it prevents the color powder from accumulating at the bottom of the color powder tank, ensuring that the color powder can smoothly enter the color powder base. There is no need to manually tap the color powder tank, reducing the labor intensity of workers. Attached Figure Description

[0015] This utility model relates to a vibrating powder-dispensing device for a plastic color mixing machine, such as... Figure 1 — Figure 5As shown, the machine includes a body 1, a feeding hopper 2 at the top of the body 1, a storage box 3 on one side of the body 1, a mixing box 4 above the storage box 3, a cover plate 5 on the mixing box 4, a powder inlet 52 on the cover plate 5, a color powder base 6 on the cover plate 5, a powder outlet 61 at the bottom of the color powder base 6, the powder outlet 61 communicating with the powder inlet 52 of the cover plate 5, a powder outlet valve 611 at the powder outlet 61, the powder outlet valve 611 being rotated by a motor, a color powder tank 62 on the color powder base 6, the lower opening of the color powder tank 62 communicating with the interior of the color powder base 6, a fixing plate 63 on the side wall of the feeding hopper 2, a connecting rod 64 on the fixing plate 63, one end of the connecting rod 64 being connected to the fixing plate 63, and the other end of the connecting rod 64 being connected to an electric vibrator 65, the other end of the electric vibrator 65 being in contact with the outer wall of the color powder tank 62.
[0016] Furthermore, the electric vibrator 65 includes a front housing 651 and a rear housing 652. The front and rear housings 651 and 652 are fixed together by fasteners and connected to a connecting rod 64. The outer wall of the front housing 651 is in contact with the outer wall of the color powder tank 62. An installation cavity 653 is formed inside the front and rear housings 651 and 652. A vibration motor 654 is installed in the installation cavity 653, and the output shaft of the vibration motor 654 is connected to an eccentric block 655.
[0017] Furthermore, the outer wall of the front housing 651 is a concave arc surface 656. Since the toner can 62 is usually circular, designing the outer wall of the front housing 651 as a concave arc surface 656, with the curvature consistent with the arc shape of the toner can 62, allows it to fit snugly against the toner can 62, which is more conducive to shaking off the toner adhering to the inner wall of the toner can 62.
[0018] Furthermore, a spring 641 is sleeved on the outer wall of the connecting rod 64. One end of the spring 641 contacts the fixing plate 63, and the other end of the spring 641 contacts the rear housing 652. With the spring 641, the elasticity of the electric vibrator 65 during vibration is improved, and the kinetic energy of the electric vibrator 65 is reduced from being transmitted to the entire plastic color matching machine, thus ensuring the service life of the plastic color matching machine.
[0019] Furthermore, the cover plate 5 is provided with two sets of color powder bases 6 and color powder tanks 62, and the corresponding side wall of the feed hopper 2 is provided with two sets of fixing plates 63, connecting rods 64 and electric vibrators 65. The number of electric vibrators 65 can be set according to the number of color powder tanks 62 on the plastic color mixing machine.
[0020] This utility model discloses a vibrating powder dispensing device for a plastic color mixing machine. It mainly consists of a fixed plate 63 installed on the side wall of the feed hopper 2, with a connecting rod 64 mounted on the fixed plate 63. One end of the connecting rod 64 passes directly through the fixed plate 63 and connects to a fastener, while the other end passes directly through an electric vibrator 65 and connects to a fastener. Both ends of the connecting rod 64 are connected to fasteners. The electric vibrator 65 is directly sleeved on the connecting rod 64 but is not fixed to it. A spring 641 is sleeved on the outer wall of the middle section of the connecting rod 64, pressing against one side of the outer wall of the electric vibrator 65. The other side of the electric vibrator 65 is in contact with the color powder tank 62. During operation, the vibrating motor 654 in the electric vibrator 65 drives the eccentric block 655 to rotate. Since the eccentric block 655 is eccentrically set, it will generate centrifugal force when it rotates at high speed, thereby causing the entire vibrating motor 654 to vibrate. The vibrating motor 654 is fixed in the front and rear housings 651 and 652, so that the front and rear housings 651 and 652 vibrate together. Since the electric vibrator 65 is not fixed to the connecting rod 64, and under the elastic force of the spring 641, the front housing 651 of the electric vibrator 65 can fit against the outer wall of the pigment tank 62 when vibrating, and transfer kinetic energy to the pigment tank 62, causing the pigment tank 62 to vibrate, thereby shaking off the pigment adhering to the inner wall. This solution provides a vibrating powder dispensing device for a plastic color mixing machine. It utilizes the centrifugal force generated by the high-speed rotation of the eccentric block 655 driven by the vibrating motor 654 to cause the electric vibrator 65 to vibrate, and transmits the kinetic energy of the vibration to the color powder tank 62, causing the color powder adhering to the inner wall of the color powder tank 62 to be dispensing. On the one hand, this prevents the color powder from adhering to the inner wall of the color powder tank 62, reducing waste, and on the other hand, it prevents the color powder from accumulating at the bottom of the color powder tank 62, ensuring that the color powder can smoothly enter the color powder base 6. There is no need to manually tap the color powder tank 62, reducing the labor intensity of workers.
