Description

Technical Field

[0001] This utility model relates to the field of mixing devices, and in particular to a mixing device for dyeing granular raw materials. Background Technology

[0002] For the production of some colorless raw materials, dyeing is often used to improve the product's appearance, recognizability, or ease of use. Common methods for dyeing solid granular raw materials include float dyeing, masterbatch dyeing, and liquid pigment dyeing.

[0003] However, existing color masterbatch coloring methods generally involve putting colorless raw materials and colorants into a mixing chamber and mixing them using a structure such as a stirring paddle. However, the coloring effect of raw materials with this mixing structure is not uniform enough, there are color differences between the dyed products, and the coloring effect of the raw materials is also relatively poor.

[0004] Therefore, there is a need for a mixing device that can uniformly dye colorless raw materials and achieve good coloring results in granular raw materials. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, which has uneven dyeing of granular raw materials and poor coloring effect, and to provide a mixing device for dyeing granular raw materials.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A mixing device for dyeing granular raw materials includes a mounting base and a mixing chamber. The mounting base is equipped with a drive motor and a hot air blower, and the drive motor drives and connects to the mixing chamber.

[0008] The mixing chamber is provided with a storage cavity, which is a flat oval structure. The air outlet of the hot air blower is located inside the storage cavity and faces the lower end of the storage cavity. The side wall of the storage cavity is provided with a material plate. The central axis of the storage cavity is coaxially arranged with the drive shaft of the drive motor. The angle between the drive shaft of the drive motor and the horizontal plane is 30-45 degrees.

[0009] The mixing chamber has a feed inlet at one end opposite to the drive motor, and a discharge outlet is provided on the side wall of the mixing chamber. The discharge outlet is covered with a cover plate, which is detachably fixed to the discharge outlet.

[0010] Preferably, the material strip has an arc-shaped structure, with one end connected to the bottom of the storage cavity and the other end connected to the position of the storage cavity near the feed inlet. The end of the material strip near the feed inlet is inclined in the direction of rotation of the mixing chamber.

[0011] Preferably, there are multiple material strips, and each material strip is distributed at equal intervals on the side wall of the storage cavity.

[0012] Preferably, the connection between the discharge port and the storage cavity is provided with a rounded corner.

[0013] Preferably, the air outlet of the hot air blower is connected to an air duct, the air duct has a bent structure, the air outlet of the air duct passes through the feed inlet and is placed in the storage cavity, and the upper end of the air duct is close to the feed inlet.

[0014] Preferably, the feed inlet is circular, and the side of the feed inlet away from the storage cavity has an annular edge, and the feed inlet is coaxially arranged with the storage cavity.

[0015] Preferably, the mixing chamber has a flattened oval structure, and the storage cavity is coaxially arranged inside the mixing chamber.

[0016] Preferably, the lower end of the mounting base is provided with a support base, the support base including a connecting section and a support section connected to each other, the connecting section being fixed to the lower end of the mounting base, and the support section being located on the side of the mounting base that connects to the mixing chamber.

[0017] Preferably, there are multiple support bases, and each support base is symmetrically distributed on both sides of the lower end of the mounting base.

[0018] Preferably, the support base has a vibration damping pad on the side away from the mounting base, and the number of vibration damping pads is multiple, with each vibration damping pad evenly distributed at the lower end of the support base. Compared with the prior art, this utility model has the following advantages:

[0019] (1) In this scheme, the granular raw materials and pigments are placed together into the storage chamber of the mixing chamber through the feed port. The mixing chamber is driven to rotate by the drive motor, and hot air is blown into the mixture in the storage chamber by the hot air blower to heat the mixture. During the rotation of the mixing chamber, the material-carrying plate on the side wall of the storage chamber carries the mixture at the bottom out. As the mixing chamber rotates, the mixture is stirred and the granular raw materials are dyed. After the dyeing is completed, the cover is opened and the discharge port is rotated to the bottom of the storage chamber so that the dyed product can be taken out.

[0020] The flat, round storage cavity, combined with the material-carrying plates on the side walls, allows the mixture at the bottom to be flipped to the top as the mixing chamber rotates. Compared to mixing methods using a stirring paddle, this method provides a better mixing effect, resulting in a more uniform blend of raw materials and colorants. Furthermore, during the mixing process, a hot air blower heats the mixture, effectively improving the coloring effect of the raw materials. The hot air heating is also more uniform, enhancing the quality of the dyed product.

[0021] (2) The mixing chamber of this solution adopts a flat circular structure and is coaxially set with the flat circular structure of the storage cavity, so that the linear velocity of each position in the storage cavity is consistent and the turning speed of each position of the material is consistent, making the material mixing more uniform, and improving the stability of the drive motor driving the mixing chamber to rotate, thus improving the reliability of the mixing device.

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides a mixing device for dyeing granular raw materials, including a mounting base 1 and a mixing chamber 2. The mounting base 1 is equipped with a drive motor and a hot air blower, and the drive motor drives the mixing chamber 2.

[0032] The mixing chamber 2 is provided with a storage cavity 21, which has a flat oval structure. The air outlet of the hot air blower is located inside the storage cavity 21 and faces the lower end of the storage cavity 21. The side wall of the storage cavity 21 is provided with a material plate 22. The central axis of the storage cavity 21 is coaxially arranged with the drive shaft of the drive motor. The angle between the drive shaft of the drive motor and the horizontal plane is 30-45 degrees.

[0033] The mixing chamber 2 has an inlet 23 at one end opposite to the drive motor, and an outlet 24 on the side wall of the mixing chamber 2. The outlet 24 has a cover plate 25, which is detachably fixed to the outlet 24.

[0034] Working principle: Granular raw materials and colorants are placed together into the storage chamber 21 of the mixing chamber 2 through the inlet 23. The mixing chamber 2 is driven by a drive motor to rotate, and hot air is blown into the mixture in the storage chamber 21 by a hot air blower to heat the mixture. During the rotation of the mixing chamber 2, the conveyor plate 22 on the side wall of the storage chamber 21 carries the mixture from the bottom out. As the mixing chamber 2 rotates, the mixture is stirred and the granular raw materials are dyed. After dyeing, the cover plate 25 is opened and the outlet 24 is rotated to the bottom of the storage chamber 21 to remove the dyed product.

[0035] The flat, round storage cavity 21, in conjunction with the material-carrying plate 22 on the side wall, allows the mixed material at the bottom to be flipped to the top as the mixing chamber 2 rotates. Compared to mixing by a stirring paddle, this method provides a better mixing effect, resulting in a more uniform mixture of raw materials and colorants. Furthermore, during the mixing process, a hot air blower heats the mixture, effectively improving the coloring effect of the raw materials. The hot air heating is also more uniform, enhancing the quality of the dyed product.

[0036] In a preferred embodiment, the conveyor belt 22 has an arc-shaped structure. One end of the conveyor belt 22 is connected to the bottom of the storage cavity 21, and the other end is connected to the position of the storage cavity 21 near the feed inlet 23. The end of the conveyor belt 22 near the feed inlet 23 is inclined in the rotation direction of the mixing chamber 2. There are multiple conveyor belts 22, and each conveyor belt 22 is evenly distributed on the side wall of the storage cavity 21.

[0037] The arc-shaped conveyor plate 22, which is inclined in the direction of rotation of the mixing chamber 2, can flip the bottom mixture up and transfer more of it to the position near the bottom of the storage chamber 21, which is also the position directly opposite the air duct outlet. This can improve the temperature of the relatively low-temperature mixture that is flipped up from the bottom, making the temperature of the entire mixture more uniform and improving the uniformity of the dyeing and mixing of the materials.

[0038] Optionally, the connection between the discharge port 24 and the storage cavity 21 is rounded. This allows for a more thorough cleaning of the product inside the storage cavity 21 after dyeing.

[0039] Specifically, the air outlet of the hot air blower is connected to an air duct 11, which has a bent structure. The air outlet of the air duct 11 passes through the feed inlet 23 and is placed in the storage cavity 21. The upper end of the air duct 11 is close to the feed inlet 23.

[0040] The hot air blown out by the hot air blower is directionally transported through the air duct 11 to improve the heating effect of the mixture and thus ensure the coloring effect of the raw materials.

[0041] The feed inlet 23 is circular, and the side of the feed inlet 23 away from the storage cavity 21 has an annular edge. The feed inlet 23 and the storage cavity 21 are coaxially arranged. The mixing chamber 2 has a flat oval structure, and the storage cavity 21 is coaxially arranged inside the mixing chamber 2.

[0042] The annular edge outside the feed inlet facilitates material feeding and provides some protection for the internal materials. The discharge port is tilted upwards to ensure the maximum capacity of the storage chamber 21 at one time, thus guaranteeing the mixing efficiency of the raw materials. The mixing chamber adopts a flat-circular structure and is coaxially arranged with the flat-circular storage chamber, ensuring consistent linear velocity and material tumbling speed at all positions within the storage chamber. This results in more uniform material mixing and improves the stability of the drive motor rotating the mixing chamber, enhancing the reliability of the mixing process.

[0043] Specifically, the lower end of the mounting base 1 is provided with a support base 3. The support base 3 includes a connecting section 31 and a support section 32 that are connected to each other. The connecting section 31 is fixed to the lower end of the mounting base 3, and the support section 32 is located on the side of the mounting base 3 that is connected to the mixing chamber 2.

[0044] There are multiple support bases 3, and each support base 3 is symmetrically distributed on both sides of the lower end of the mounting base 1.

[0045] The support base 3 is provided with a vibration damping pad 33 on the side away from the mounting base 1. There are multiple vibration damping pads 33, and each vibration damping pad 33 is evenly distributed at the lower end of the support base 3.

[0046] Considering that the mixing chamber 2 connected to one side of the mounting base 1 is located outside the center of gravity of the mounting base 1, a support base 3 is set at the bottom of the mounting base 1. The support section of the support base 3 near the mixing chamber 2 is used for auxiliary support, and the shock-absorbing pad 33 at the lower end of the support base 3 is used to improve the stability and reliability of the device.

[0047] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
