Description

Technical Field

[0001] This utility model relates to the field of flower pot production equipment, and in particular to a raw material color mixing box for flower pot production. Background Technology

[0002] Plastic flower pots are a common type of flower pot. They are widely used due to their high plasticity and toughness. One of their advantages is their strong color plasticity. Before molding, different color powders can be mixed into the raw material granules to obtain plastic flower pots of different colors during molding. In order to ensure that the color of plastic flower pots in the same batch is uniform and consistent, the requirements for the uniformity of mixing between the color powder and the raw material granules are high. The mixing of color powder and raw material granules is generally carried out using a color mixing box. Therefore, it is particularly necessary to develop a raw material color mixing box for flower pot production with high uniformity of mixing between color powder and raw material granules. Summary of the Invention

[0003] The purpose of this invention is to provide a raw material mixing box for flowerpot production, which has the advantage of high uniformity of mixing of color powder and raw material particles.

[0004] The technical solution adopted is as follows:

[0005] A raw material mixing box for flower pot production includes a support frame, a mixing box at the upper end of the support frame, a feeding pipe at the upper end of the mixing box, a support pipe vertically rotatably mounted at the bottom end of the mixing box, a stirring plate mounted on the support pipe inside the mixing box, the lower end of the support pipe extending below the mixing box, a drive mechanism connected to the support pipe at the bottom of the mixing box, multiple storage pipes with open tops mounted inside the support pipe, pistons slidably mounted inside each storage pipe, multiple telescopic mechanisms vertically mounted on the support frame and connected to each piston, a first air pipe inside the support pipe, an air hole with an outward opening on the first air pipe inside the storage pipe, an air pressure balance hole at the upper end of the mixing box, a filter element mounted at the air pressure balance hole, and a discharge valve at the lower side of the mixing box.

[0006] Preferably, a second air pipe is provided above the color mixing box, and multiple air jet pipes extending into the color mixing box are vertically provided at the lower end of the second air pipe.

[0007] Preferably, a cover plate is provided between the storage pipes above the support pipe.

[0008] Preferably, the bottom of the color mixing box is a frustum shape with a higher center and lower sides.

[0009] Preferably, the drive mechanism includes a variable frequency motor, which is fixedly installed at the lower end of the color mixing box. The variable frequency motor is connected to a drive gear, and a driven gear ring is coaxially fixedly installed on the support tube. The driven gear ring meshes with the drive gear.

[0010] Preferably, the telescopic mechanism is a hydraulic telescopic cylinder.

[0011] Compared to existing technologies, the advantages are:

[0012] This invention involves storing different color powders in different storage tubes according to a specific ratio. The lifting mechanism is adjusted according to the amount of each color powder to make it level with the top of the storage tube. The extension speed of each telescopic mechanism is adjusted so that each piston reaches the top of the storage tube simultaneously, allowing the different color powders to be evenly mixed with the material. When the color powder reaches the top of the storage tube, the gas ejected from the vent disperses the color powder, facilitating its mixing with the material. Through the above process, the color powder and the material are evenly mixed. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 4 As shown:

[0019] A raw material mixing box for flower pot production includes a support 1, a mixing box 2 at the upper end of the support 1, the mixing box 2 being cylindrical in shape, an upper cover at the upper end of the mixing box 2, and a feed pipe 3 on the upper cover. Granular raw materials are fed into the mixing box 2 through the feed pipe 3. A dust cover 4 is detachably installed at the upper end of the feed pipe 3. A support pipe 5 is vertically rotatably installed at the bottom end of the mixing box 2, the support pipe 5 being rotatably and sealingly connected to the bottom end of the mixing box 2, and the support pipe 5 extending coaxially with the mixing box 2.

[0020] A stirring plate 6 is installed on the support tube 5 inside the color mixing box 2. The lower end of the support tube 5 extends to the bottom of the color mixing box 2. A drive mechanism connected to the support tube 5 is installed below the color mixing box 2. The drive mechanism drives the support tube 5 to rotate. The stirring plate 6 on the outside of the support tube 5 is used to stir and mix the inside of the color mixing box 2. Multiple storage tubes 10 with open tops are installed inside the support tube 5. The upper ends of the storage tubes 10 are all higher than the upper ends of the support tube 5. The storage tubes 10 are fixedly connected to the support 1 by longitudinal beams. A piston 11 is slidably installed inside each storage tube 10. Multiple telescopic mechanisms 12 are vertically installed on the support 1, which are connected to each piston 11. The telescopic mechanisms 12 control the pistons 11 to rise and fall inside the storage tubes 10. The storage tubes 10 are used to hold color powder.

[0021] A first air pipe 14 is provided inside the support pipe 5. The first air pipe 14 extends from the inside of the support pipe 5 to the bottom of the color mixing box 2 and is connected to an external high-pressure air pump. An air hole 15 with an outward opening is provided on the first air pipe 14 inside the storage pipe 10. When the telescopic mechanism 12 drives the piston 11 to rise and push the color powder in the storage pipe 10 out from the top, the gas sprayed out of the air hole 15 blows the color powder into the color mixing box 2, so that the color powder can be evenly mixed with the granular raw material. A discharge valve 20 is provided at the lower side of the color mixing box 2. The discharge valve 20 is used to discharge the granular raw material after color mixing.

[0022] Before coloring the granular raw materials, open the top cover of the color mixing box 2 and place different color powders into different storage tubes 10 according to the proportions. Adjust the corresponding lifting mechanism according to the different quantities so that the color powder is flush with the top of the storage tube 10. Close the top cover of the color mixing box 2 and put the granular raw materials into the color mixing box 2 through the feed pipe 3. Start the drive mechanism to drive the support tube 5 to rotate. Adjust the extension speed of each telescopic mechanism 12 so that each piston 11 reaches the top of the storage tube 10 at the same time. During the upward movement of the piston 11, the color powder is pushed out from the top of the storage tube 10. The gas sprayed from the air hole 15 blows the color powder into the color mixing box 2. The color powder is evenly mixed with the granular raw materials. The top of the color mixing box 2 is provided with an air pressure balance hole 18 and a filter element 19 is provided at the air pressure balance hole 18. After the color powder is pushed out, continue stirring for a period of time. Then open the discharge valve 20 to discharge the color-mixed granular raw materials.

[0023] Example 2: A raw material mixing box for flower pot production includes a support 1, a mixing box 2 is provided on the upper end of the support 1, the mixing box 2 is cylindrical in shape, the upper end of the mixing box 2 is covered with an upper cover, and a feed pipe 3 is provided on the upper cover. Granular raw materials are fed into the mixing box 2 through the feed pipe 3. A dust cover 4 is detachably provided on the upper end of the feed pipe 3. A support pipe 5 is vertically rotatably provided at the bottom end of the mixing box 2. The support pipe 5 is rotatably and sealingly connected to the bottom end of the mixing box 2, and the support pipe 5 extends coaxially with the mixing box 2. The inner bottom of the mixing box 2 is a frustum shape with a high middle and low sides, which facilitates the granular raw materials to gather to the outside.

[0024] A stirring plate 6 is installed on the support tube 5 inside the color mixing box 2. The lower end of the support tube 5 extends below the color mixing box 2. A drive mechanism connected to the support tube 5 is installed below the color mixing box 2. The drive mechanism includes a variable frequency motor 7, which is fixedly installed at the lower end of the color mixing box 2. The variable frequency motor 7 is connected to a drive gear 8. A driven gear ring 9 is coaxially fixedly installed on the support tube 5, and the driven gear ring 9 meshes with the drive gear 8.

[0025] The drive mechanism drives the support tube 5 to rotate, and the stirring plate 6 on the outside of the support tube 5 stirs and mixes the color mixing box 2. The support tube 5 is equipped with multiple storage tubes 10 with open tops. The upper ends of the storage tubes 10 are all higher than the upper ends of the support tube 5. The storage tubes 10 are fixedly connected to the bracket 1 by longitudinal beams. Pistons 11 are slidably installed in each storage tube 10. The bracket 1 is vertically equipped with multiple telescopic mechanisms 12 that are connected to each piston 11. The telescopic mechanism 12 is a hydraulic telescopic cylinder. The hydraulic telescopic cylinder with adjustable telescopic speed is existing technology and will not be described in detail here. The telescopic mechanism 12 controls the pistons 11 to rise and fall in the storage tubes 10. The storage tubes 10 are used to hold color powder. A cover plate 13 is installed between the storage tubes 10 above the support tube 5. The cover plate 13 reduces the entry of particulate raw materials and color powder into the support tube 5.

[0026] A first air pipe 14 is installed inside the support pipe 5, extending from the inside of the support pipe 5 to the bottom of the color mixing box 2 and connected to an external high-pressure air pump. An outward-facing air hole 15 is provided on the first air pipe 14 inside the storage pipe 10. When the telescopic mechanism 12 drives the piston 11 to rise and push the color powder in the storage pipe 10 out from the top, the gas ejected from the air hole 15 blows the color powder into the color mixing box 2, facilitating uniform mixing of the color powder with the granular raw materials. A second air pipe 16 is installed above the color mixing box 2. The lower end of the second air pipe 16 is vertically provided with multiple air jet pipes 17 extending into the color mixing box 2. The second air pipe 16 is connected to an external high-pressure air pump from the top of the color mixing box 2. The air jet pipes 17 blow air downwards to make the color powder move downwards and mix with the granular raw materials. The upper end of the color mixing box 2 is provided with an air pressure balance hole 18, and a filter element 19 is provided at the air pressure balance hole 18 to balance the gas pressure inside and outside the color mixing box 2.

[0027] The specific working process is as follows: Before coloring the granular raw materials, open the upper cover of the color mixing box 2, and put different color powders into different storage tubes 10 according to the proportion. Adjust the corresponding lifting mechanism according to the different quantities so that the color powder is flush with the upper end of the storage tube 10. Close the upper cover of the color mixing box 2, put the granular raw materials into the color mixing box 2 from the feed pipe 3, start the drive mechanism to drive the support pipe 5 to rotate, adjust the extension speed of each telescopic mechanism 12 so that each piston 11 reaches the uppermost end of the storage tube 10 at the same time. During the upward movement of the piston 11, the color powder is pushed out from the upper end of the storage tube 10. The gas sprayed from the air hole 15 blows the color powder into the color mixing box 2. The air nozzle blows air downward to make the color powder move downward and mix with the granular raw materials. The color powder is evenly mixed with the granular raw materials. After the color powder is pushed out, continue stirring for a period of time, and then open the discharge valve 20 to discharge the color-mixed granular raw materials.
