Description

Technical Field

[0001] The utility model relates to the technical field of particle mixing equipment, in particular to a multi-color porcelain-like sand-fixed proportion mixer. Background Art

[0002] Imitation porcelain sand is sand made of new nanomaterials. It is widely used in children's toy sand fields, fish tanks, potted plants, and even as fillings for rattle toys due to its health, environmental protection, flame retardancy, smooth surface, and high hardness. In the production process of imitation porcelain sand, bone particles are first processed, and then the bone particles are processed into finished sand with different surface colors, such as white, pink, blue, yellow, purple, etc. in the coloring process. In the packaging process, it is usually necessary to mix imitation porcelain sands of different colors according to weight ratio to form colored sand, so as to meet the aesthetic effects required in different usage scenarios.

[0003] At present, the mixing process adopted for multi-color imitation porcelain sand is to weigh each color of imitation porcelain sand according to the weight ratio, pour the weighed imitation porcelain sand into a mixer for stirring and mixing, output from the output port of the mixer after mixing, and package the mixed color imitation porcelain sand after final screening. The work of weighing each color of imitation porcelain sand in this mixing process is relatively cumbersome, especially when it is necessary to mix four or five or more colors of imitation porcelain sand, the mixing work as a whole will reflect low work efficiency. Moreover, the use of stirring mixing in the mixer will increase the surface wear of the sand grains, and even increase the breakage rate of the sand grains, reducing the output of qualified products. For this reason, it is necessary to provide a mixing method with high mixing efficiency and less sand damage to improve the above situation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a multi-color porcelain-like sand fixed-proportion mixer with high mixing efficiency, less sand damage and high mixing accuracy.

[0006] As a preferred technical solution, the flow control mechanism includes a flow gate movably installed along the radial direction on the material guiding structure, and a flow fixer for fixing the position of the flow gate is provided on the material guiding structure.

[0007] As a preferred technical solution, the flow fixer includes a gate fixing magnet.

[0008] As a preferred technical solution, the spreading structure includes a spreading trough, and the spreading trough is arranged to spread sand in the conveying direction of the belt conveyor.

[0009] As a preferred technical solution, the belt conveyor device includes a conveyor belt, and anti-spill baffles are respectively provided on both sides of the conveyor belt.

[0010] As a preferred technical solution, a screening machine is provided at the output end of the belt conveyor device, and a mixed material container is provided at the qualified material output port of the screening machine.

[0011] As a preferred technical solution, a dust removal device is installed on the frame at the output end of the belt conveyor device.

[0012] Due to the adoption of the above technical scheme, a multi-color porcelain-like sand fixed-proportion mixer includes a frame, a belt conveyor device is installed on the frame, and a plurality of raw material containers arranged in sequence along the conveying direction are arranged on the frame above the belt conveyor device, and a spreading structure for spreading sand toward the belt conveyor device is provided below each of the raw material containers, and a material guide structure for guiding materials toward the corresponding spreading structure is provided at the bottom of each of the raw material containers, and a flow control mechanism is provided on the material guide structure.

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the multi-color imitation porcelain sand fixed proportion mixer includes a frame 1, which is a carrier of various functional structures. Its specific structure can be easily set by those skilled in the art according to conventional technical means, and will not be repeated here and the specific structure is not illustrated in detail in the figure.

[0021] A belt conveyor device 2 is installed on the frame 1. Conventionally, the belt conveyor device 2 includes a conveyor belt. Of course, at least two belt rollers are installed on the frame 1. The conveyor belt is installed between the belt rollers. A conveying drive motor is provided between one of the belt rollers and the frame 1. The structural principle of the belt conveyor device 2 is easily derived by those skilled in the art based on conventional belt conveyor technology, and will not be described in detail here.

[0022] A plurality of raw material containers 3 are arranged in sequence along the conveying direction on the frame 1 above the belt conveyor 2. The raw material containers 3 store imitation porcelain sand for mixing, and each raw material container 3 stores only one color of imitation porcelain sand. The above arrangement in sequence along the conveying direction does not limit the spatial position relationship that the raw material containers 3 are arranged in a row along the conveying direction. As long as the arrangement of the plurality of raw material containers 3 allows the imitation porcelain sand in the containers to be output sequentially in the conveying direction, the raw material containers 3 are arranged in sequence in the conveying direction.

[0023] A spreading structure 4 for spreading sand toward the belt conveyor 2 is provided below each of the raw material containers 3. The spreading allows the sand reaching the belt conveyor 2 to form a relatively ideal dispersed state, and the porcelain-like sand spread thereafter can naturally mix with the porcelain-like sand spread previously, thereby forming a continuous mixing operation.

[0024] The spreading structure 4 of this embodiment includes a spreading groove, which is of course arranged obliquely to form free spreading with the good fluidity of the imitation porcelain sand. Preferably, the spreading groove is arranged to spread the sand in the conveying direction of the belt conveyor 2, so that the spread sand can be concentrated in the middle area of ​​the belt conveyor 2, reducing the waste of sand spilling from the side of the belt conveyor 2. Preferably, anti-spill baffles 21 are respectively provided on both sides of the conveyor belt to block the side spilling and further avoid the waste of sand spilling.

[0025] The bottom of each raw material container 3 is provided with a material guiding structure 5 for guiding the material toward the corresponding spreading structure 4. Since the imitation porcelain sand itself has a smooth surface, high hardness and good fluidity, the material guiding structure 5 can be implemented by a vertical or inclined material guiding pipe, etc., so that the imitation porcelain sand itself flows to form the material guide.

[0026] The material guide structure 5 is provided with a flow control mechanism 6, which makes the outflow speed of the imitation porcelain sand match the conveying speed of the belt conveyor 2, so that the number of sand grains within a fixed length range on the belt conveyor 2 is relatively stable. Therefore, during the operation of the belt conveyor 2, the weight of the multi-color imitation porcelain sand sprinkled sequentially on the conveyor belt of the same length range forms a fixed ratio, achieving the purpose of fixed ratio mixing.

[0027] The flow control mechanism 6 of this embodiment includes a flow gate 61 movably installed along the radial direction on the material guide structure 5, and a flow fixer 62 for fixing the position of the flow gate 61 is provided on the material guide structure 5. The cross-sectional area of ​​the flow channel at the material guide structure 5 is changed by the radial movement of the flow gate 61, so as to achieve the purpose of controlling the flow of the imitation porcelain sand. This embodiment shows that the flow gate 61 is arranged at the port of the material guide structure 5, and a guide groove for guiding the movement direction of the flow gate 61 is provided at the port of the material guide structure 5. Based on the inclined arrangement of the material guide structure 5 in this embodiment, the flow gate 61 is preferably movably installed in a manner that can close the channel in the material guide structure 5 from top to bottom.

[0028] The flow fixer 62 includes a gate fixing magnet, which fixes the position of the flow gate 61 by magnetic attraction, so as to avoid the extrusion and impact of the sand flow process affecting the position of the flow gate 61, and ensure the long-lasting and constant flow output of the imitation porcelain sand. Based on this, the material guide structure 5 and the flow gate 61 are preferably made of strong magnetic materials such as steel and iron. Of course, the flow fixer 62 can also be implemented by lateral fastening bolts, etc., which is an equivalent transformation method of the flow fixer 62 and should also be within the scope of the flow fixer 62.

[0029] like Figure 4As shown, a screening machine 7 is provided at the output end of the belt conveyor 2, and the sand particles that do not meet the particle size requirements or are broken in the raw materials are screened out by the screening machine 7. The screening machine 7 can be implemented by a vibrating screen, a rolling screen, etc., which is not limited here; conventionally, the screening machine 7 has an output port for the screened qualified materials, that is, a qualified material output port. Preferably, a mixed material container 8 is provided at the qualified material output port of the screening machine 7 to store the mixed material. A packaging output port, etc. can be provided on the mixed material container 8 to directly carry out subsequent packaging operations. The packaging output port can also use structural modes such as guides and gates, and the mixed material is self-flowing to form an output, which is easy to obtain for those skilled in the art, and will not be repeated here and is not illustrated in detail in the figure. In actual settings, if the second half of the belt conveyor 2 needs to be lifted and transported due to site reasons, a support sheet 22 should preferably be provided on the conveyor belt in the belt conveyor 2 to ensure that the imitation porcelain sand can be lifted smoothly.

[0030] Preferably, a dust removal device is installed on the frame 1 at the output end of the belt conveyor 2 to remove dust and other light impurities adhering to the imitation porcelain sand particles. The dust removal device can be implemented by fan backblowing or negative pressure suction, etc., which is not limited here.

[0031] When this embodiment is used, the imitation porcelain sands of various colors to be mixed are respectively filled into the corresponding raw material containers 3, and the belt conveyor 2 is turned on. The position of the corresponding flow gate 61 is adjusted according to the required weight ratio of the mixture, so that the imitation porcelain sands in the corresponding raw material container 3 can form the output of the required flow rate. Here, the position of the flow gate 61 can be adjusted by pre-making a caliper set according to several common weight ratios. The caliper is used to cushion the lower position of the end of the corresponding material guide structure 5. When the flow gate 61 is pushed down to the position in contact with the caliper, the caliper is withdrawn, and the flow gate 61 reaches the required opening size, thereby realizing the rapid adjustment of the position of the flow gate 61.

[0032] During the continuous operation of the belt conveyor 2, various colors of imitation porcelain sand are sprinkled thereon in turn, and within the range of the fixed length of the conveyor belt, the various colors of imitation porcelain sand sprinkled are naturally mixed in a fixed proportion. Thus, this embodiment forms a continuous mixing operation of multi-color imitation porcelain sand, and the mixing efficiency is high. The mixing process only involves the flow and spreading of the sand grains themselves, and the sand grains have little wear and tear on each other, and little extrusion damage, which can significantly reduce the damage to the sand grains and ensure the output of qualified products. This embodiment uses flow control instead of weighing to achieve continuous fixed-proportion mixing of multi-color imitation porcelain sands, and the error can be controlled within 3 to 4 kg / t, with high mixing accuracy.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
