Description

Technical Field

[0001] The present application relates to the field of color matching machine equipment, and in particular to an automatic feeding color matching machine. Background Art

[0002] At present, in industries with more color matching or formula requirements, such as the wire and cable industry, it is often necessary to use outer insulation layers of different colors to mark cables of various specifications and functions. Therefore, there are many types of colors that need to be mixed during the production process, which leads to the need to frequently change the composition and ratio of masterbatch and auxiliary materials during the production process. In some specific occasions, it may be necessary to change the production of multiple colors in a relatively short period of time.

[0003] In the related art, the Chinese invention patent with publication number CN108636179A discloses a color matching device for garden landscape painting, which solves the problem that the color matching and mixing means are inefficient and cannot meet the construction needs when facing large-scale construction projects. Different single colors enter the mixing chamber through the pigment inlet, and then the power device drives the shaft to rotate through the transmission structure such as the coupling, and the adjustment component rotates with the shaft, and drives the sleeve to rotate at the same time. When the counterweight block expands to the set position, the expansion angle of the centrifugal rod changes periodically, and the connecting rod drives the sleeve to make periodic linear motion, so that the spiral blade not only produces a circumferential shearing effect on the raw material liquid, but also produces an axial pushing motion on the raw material liquid, so that the pigment is avoided from being stratified during the stirring process, and the pigment can be ensured to be mixed quickly, and the efficiency is greatly improved. In the color matching process of the pigment of the wire and cable, similar equipment is also commonly used, that is, multiple pigments are quantitatively added to the mixing box, and after the stirring shaft in the mixing box is completely stirred, the pigment is taken out from the mixing box and used for the production of the wire and cable.

[0004] Regarding the above-mentioned related technologies, the inventor believes that in actual use, the existing color matching machines use stirring to mix materials, and it takes a long time to mix the materials evenly, making it difficult to achieve rapid replacement of multiple colors in production, which results in the need for subsequent equipment to shut down and wait for a long time for the color matching process to be completed, thereby reducing the overall processing efficiency. Summary of the invention

[0005] In order to solve the problem of low material mixing efficiency of existing color matching machines, the present application provides an automatic feeding color matching machine.

[0006] The automatic feeding color matching machine provided in this application adopts the following technical solution:

[0007] An automatic feeding color matching machine comprises a main mixing cavity, wherein a main mixing chamber is arranged in the main mixing cavity, a plurality of feed pipes are connected to the main mixing chamber, a material dividing structure is arranged in the main mixing cavity, a storage bin is connected below the main mixing cavity, materials flow into the main mixing cavity through the plurality of feed pipes, materials flow into the storage bin after being mixed in the main mixing cavity by the material dividing structure, the material dividing structure comprises a material dividing block fixedly arranged in the main mixing cavity, the edge of the material dividing block is in contact with the inner wall of the main mixing cavity, and a plurality of material running holes are opened inside the material dividing block.

[0008] By adopting the above technical scheme, a variety of materials enter the main mixing chamber from the feed pipe for pre-mixing, and then the materials pass through the dividing block and naturally fall into the storage bin from a plurality of feeding holes. During the falling process, the pre-mixed materials are separated again through a plurality of feeding holes and fall into the storage bin, so that a variety of materials can be naturally dispersed and mixed without stirring. This process is carried out simultaneously with the flow of materials. The materials collected in the storage bin can be directly used for production, and subsequent equipment does not need to wait for a long time, and continuous and uninterrupted material transportation can be achieved.

[0009] Preferably, one side of the dividing block close to the main mixing chamber is in the shape of an arc with a raised center, a plurality of the feeding holes are radially distributed along the surface of the dividing block, and a plurality of rows of the feeding holes are circumferentially distributed along the surface of the dividing block, and the surface of the dividing block close to the main mixing chamber is polished.

[0010] By adopting the above technical scheme, the arc-shaped and smooth-surfaced dividing block can allow the material to flow freely along the surface of the dividing block, which is more conducive to the full flow and mixing of the material. At the same time, the material can also be evenly spread over the entire surface of the dividing block under the action of its own gravity, further improving the adequacy of the dividing block for material separation, thereby effectively improving the final material mixing quality.

[0011] Preferably, the material distribution structure also includes a guide block, which is cylindrical and has an outer surface fitted in the main mixing chamber, a first mixing chamber is opened inwardly at one end face of the guide block, and a second mixing chamber is opened inwardly at the other end face of the guide block, the first mixing chamber is located between the material distribution block and the feed pipe, the material distribution block is located in the second mixing chamber, the first mixing chamber and the second mixing chamber are connected to each other, and a drop hole is formed at the connection between the first mixing chamber and the second mixing chamber, the drop hole is concentrically arranged with the material distribution block, and the projection area of ​​the drop hole in the horizontal direction is smaller than the projection area of ​​the material distribution block in the horizontal direction.

[0012] By adopting the above technical solution, the setting of the guide block can guide the materials that will pass through the dividing block, and various materials flow and converge along the surface of the first mixing cavity, thereby effectively improving the adequacy of mixing of various materials. At the same time, since the area of ​​the drop hole is smaller than the surface area of ​​the dividing block, when the material falls from the drop hole, the material will first reach the center of the dividing block, and then flow to the edge of the dividing block, thereby further helping the materials to be separated and mixed.

The area of ​​the drop hole is set to 1 / 4 of the surface area of ​​the material distribution block, which can effectively improve the convergence effect of the first mixing chamber on the materials. The edges of the first mixing chamber are all rounded, which can effectively reduce the generation of material residue dead corners and reduce material waste.

[0016] By adopting the above technical solution, when mixing materials, air can be ventilated into the second mixing chamber through the auxiliary hole, and the airflow can blow the flowing materials, which is more conducive to the full mixing of various materials. When it is necessary to clean the inside of the main mixing chamber, cleaning liquid can be injected into the auxiliary hole through the liquid supply device, so as to achieve the effect of cleaning the main mixing chamber and the material distribution block.

[0017] Preferably, the level of one end of the auxiliary hole close to the second mixing chamber is lower than the level of the other end.

[0018] By adopting the above technical solution, the inclined setting of the auxiliary hole can effectively reduce the possibility of the material in the main mixing chamber flowing back in the auxiliary hole.

[0019] Preferably, a feeding device is provided at one end of each feed pipe away from the main mixing chamber, and the feeding device includes a first loading bin, a transition hopper and a second loading bin connected in sequence from top to bottom, the second loading bin is connected to the feed pipe, a conveying screw is provided in the feed pipe along the length direction, the conveying screw is connected to a driving motor, a weight sensor is provided at the transition hopper, a first valve is provided between the first loading bin and the transition hopper, a second valve is provided between the transition hopper and the second loading bin, and a third valve is provided between the second loading bin and the feed pipe.

After the weighing is completed, the second valve is opened to put the material between the second loading bin and finally into the feed pipe, thereby realizing the precise control of the ratio of various materials, so as to facilitate the adjustment of the final required materials. At the same time, by reading the weight change of the weight sensor within a certain period of time, the actual amount of material added during the period can also be obtained, so that the staff can more conveniently monitor and adjust the materials actually involved in the mixing process.

[0021] Preferably, the feed pipe and the main mixing chamber are both connected with a quick discharge pipe, and a discharge valve is provided at the connection between the quick discharge pipe, the feed pipe and the main mixing chamber.

[0022] By adopting the above technical solution, the setting of the rapid discharge channel can facilitate the staff to quickly discharge the materials in the feed pipe and the main mixing chamber under special circumstances, thereby improving the convenience of subsequent maintenance.

[0040] Reference Figure 2 and Figure 4 The material distribution structure 3 includes a material distribution block 31 fixedly arranged in the main mixing chamber 1, the edge of the material distribution block 31 is in contact with the inner wall of the main mixing chamber 1, and a plurality of material passage holes 311 are provided inside the material distribution block 31. The side of the material distribution block 31 close to the main mixing chamber 11 is in an arc shape with a raised center, and a plurality of material passage holes 311 are radially distributed along the surface of the material distribution block 31, and a plurality of material passage holes 311 are circumferentially distributed along the surface of the material distribution block 31, and the surface of the material distribution block 31 close to the main mixing chamber 11 is polished. The material distribution block 31 with an arc shape and a smooth surface can make the material flow freely along the surface of the material distribution block 31, which is more conducive to the full flow and mixing of the material, and at the same time, the material can evenly cover the entire surface of the material distribution block 31 under the action of its own gravity, further improving the adequacy of the material separation of the material distribution block 31, thereby effectively improving the final material mixing quality.

[0041] Reference Figure 2 and Figure 4The material distribution structure 3 also includes a guide block 32, which is cylindrical and has an outer surface that fits in the main mixing chamber 11. A first mixing chamber 321 is opened inwardly at one end surface of the guide block 32, and a second mixing chamber 322 is opened inwardly at the other end surface of the guide block 32. The first mixing chamber 321 is located between the material distribution block 31 and the feed pipe 2, and the material distribution block 31 is located in the second mixing chamber 322. The first mixing chamber 321 and the second mixing chamber 322 are located in the main mixing chamber 11. The cavities 322 are interconnected, and a drop hole 323 is formed at the connection between the first mixing cavity 321 and the second mixing cavity 322. The drop hole 323 is concentrically arranged with the dividing block 31, and the projection area of ​​the drop hole 323 in the horizontal direction is smaller than the projection area of ​​the dividing block 31 in the horizontal direction. Preferably, the projection area of ​​the drop hole 323 in the horizontal direction is smaller than 1 / 4 of the projection area of ​​the dividing block 31 in the horizontal direction. The edges of the first mixing cavity 321 are rounded.

[0042] Reference Figure 2 and Figure 4 , the guide block 32 is provided with a plurality of auxiliary holes 324, one end of the auxiliary holes 324 is connected to the second mixing chamber 322, and the other end of the auxiliary holes 324 is connected to the outer surface of the guide block 32, and the surface of the main mixing chamber 1 is provided with a plurality of openings corresponding to the auxiliary holes 324, and the auxiliary holes 324 are connected to an air supply or liquid supply device arranged outside the main mixing chamber 1, and the level of the auxiliary hole 324 close to one end of the second mixing chamber 322 is lower than the level of the other end. When mixing materials, the second mixing chamber 322 can be ventilated through the auxiliary holes 324, and the airflow can blow the flowing materials, which is more conducive to the full mixing of various materials. When it is necessary to clean the inside of the main mixing chamber 1, a cleaning liquid can be injected into the auxiliary holes 324 through the liquid supply device, so as to achieve the effect of cleaning the main mixing chamber 11 and the dividing block 31. The inclined setting of the auxiliary holes 324 can effectively reduce the possibility of the material in the main mixing chamber 11 flowing back in the auxiliary holes 324.

[0043] The implementation principle of an automatic feeding color matching machine in the embodiment of the present application is as follows: a plurality of materials enter the main mixing chamber 11 from the feed pipe 2 for premixing, and then the materials pass through the dividing block 31 and naturally fall from the plurality of material holes 311 into the storage bin 4. During the falling process, the premixed materials pass through the plurality of material holes 311 and separate again, and fall into the storage bin 4, so that a plurality of materials can be naturally dispersed and mixed without stirring. This process is carried out simultaneously with the flow of the materials. The materials collected in the storage bin 4 can be directly used for production, and the subsequent equipment does not need to wait for a long time, and continuous and uninterrupted material transportation can be realized. The arc-shaped and smooth dividing block 31 allows the materials to flow freely along the surface of the dividing block 31, which is more conducive to the full flow and mixing of the materials, and at the same time, the materials can be evenly spread over the entire surface of the dividing block 31 under the action of their own gravity. The setting of the guide block 32 can guide the materials that will pass through the dividing block 31, and various materials flow and converge along the surface of the first mixing chamber 321, thereby effectively improving the adequacy of the mixing of various materials. At the same time, since the area of ​​the drop hole 323 is smaller than the surface area of ​​the dividing block 31, when the material falls from the drop hole 323, the material will first reach the center of the dividing block 31, and then flow to the edge of the dividing block 31, thereby further helping the materials to be separated and mixed.

[0044] The material enters the transition hopper 52 from the first loading bin 51, and the material is accurately weighed by the weight sensor 56 in the transition hopper 52, so that the staff can conveniently adjust the ratio of various materials. After the weighing is completed, the second valve 58 is opened to put the material into the second loading bin 53 and finally enter the feed pipe 2, thereby realizing the precise control of the ratio of various materials, so as to facilitate the adjustment of the final required materials. At the same time, by reading the weight change of the weight sensor 56 in a certain period of time, the actual amount of material added in the period of time can also be obtained, so that the staff can more conveniently monitor and adjust the materials actually involved in the mixing process.

[0045] In this embodiment, a liquid level sensor is also inserted into the main mixing chamber 11. The liquid level sensor can detect the liquid level height in the main mixing chamber 11 in real time. When the material distribution mechanism itself fails and causes material blockage, etc., the staff can promptly sense the abnormal increase in the liquid level in the main mixing chamber 11 through the liquid level sensor, so as to carry out maintenance in time.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
