Technical Field

[0001] The invention relates to a mixing device, in particular to a device for mixing glue. Background Art

[0002] The aviation manufacturing industry requires adhesives for bonding, sealing, potting and other processes. Many adhesives require their components to be measured and mixed evenly before use. Manual mixing requires a lot of manpower and is difficult to achieve a uniform effect, which can easily lead to quality defects. Especially when the viscosity of the adhesive is high, mixing is more difficult and the quality risk is higher.

[0003] Some adhesives are packaged in one-piece AB cartridges, which can be easily mixed using special tools. However, this packaging method is expensive, has limited capacity, and is disposable, becoming industrial waste after use.

[0004] The glue mixers on the market are generally large-scale equipment that loads each component of the adhesive into a storage barrel separately, transports it to the outlet through a pipeline, and then mixes it in a static mixer at the outlet before discharging it. This type of equipment is suitable for continuous production lines, but is not suitable for many aviation manufacturing companies with small batches and a wide variety of products.

[0026] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. These embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0027] A vertical magnetic glue mixing device, as shown in the attached Figures 1 to 3 As shown, it includes a stirring drum 1, a stirring claw 2, a driving ring 3, a base 4, a control box 5, and a driving mechanism 6.

[0028] The mixing drum 1 is placed vertically with its axis, and an openable opening is provided on the mixing drum for taking in and placing the glue and the mixing claws. At least one of the two end surfaces of the mixing drum can be provided with an end cover 11 as an openable opening, for example, Figure 3 As shown in the figure, the upper end surface of the mixing drum is used as the end cover 11, and the bottom of the mixing drum is installed on the base 4.

[0029] The base 4 is provided with a cantilever 41, and the driving ring 3 is arranged around the outer circumference of the mixing drum 1 and connected to the cantilever 41. The driving mechanism controls the driving ring 3 and the mixing drum 1 to rotate relative to each other along the circumferential direction. The inner circumference of the driving ring and the outer circumference of the mixing drum can be in contact or not, but no contact will not generate friction. In order to facilitate the connection between the driving ring 3 and the cantilever 41, the driving mechanism controls the driving ring 3 and the mixing drum 1 to rotate relative to each other along the circumferential direction. Figure 3 As shown, the upward end of the drive ring 3 is provided with an end surface 32, combined with the attached Figure 4 As shown, at least two magnets A31 are evenly distributed in the circumferential direction inside the driving ring 3 .

[0030] The stirring claw 2 is placed in the stirring drum 1, and a magnet B21 is arranged inside the stirring claw 2. Figure 5 As shown, the stirring claw 2 can be formed by at least two claw petals 22 arranged in a radial shape, and the magnet B21 is built in the top of the claw petal 22. Figure 6 As shown, the stirring claw 2 can also be composed of a rim 23 and an impeller 24, wherein the rim 23 surrounds and connects to the top of the impeller 24, and the magnets B21 are built into the rim 23 and are evenly distributed along the circumference thereof.

[0031] The driving ring is arranged around the outer circumference of the mixing drum, and the stirring claw is placed inside the mixing drum. The mixing drum is filled with glue liquid and is relatively heavy. It is usually designed to set a fixing groove 43 on the base 4, and the bottom of the mixing drum 1 is placed in the fixing groove 43 and fixed on the base. The driving ring rotates along the circumference of the mixing drum, and the magnetic field coupling of magnet A and magnet B is utilized. The magnetic attraction of magnet A to magnet B drives the stirring claw to rotate in the mixing drum in the same direction as the driving ring, thereby stirring and mixing the glue liquid of different components in the mixing drum. To this end, on the one hand, the magnet B on the stirring claw and the magnet A on the mixing drum should be basically at the same height, so that the driving ring can capture the stirring claw, for example, attached Figure 3 As shown, this purpose can be achieved by setting a vertical shaft 25 on the stirring claw 2. The viscosity of the adhesive is large, and the stirring claw is in the adhesive liquid. The vertical shaft and the bottom surface of the stirring drum basically do not produce large friction. On the other hand, when the magnet A31 and the magnet B21 are set, the magnet A31 and the magnet B21 are oppositely polarized to generate magnetic attraction. Figure 4 and 5 , 4 and 6 indicate a magnet pole arrangement and relationship, which forms radial magnetization along the radial direction of the mixing drum, so that the axis of the stirring claw is basically consistent with the axis of the mixing drum, and also improves the magnetic attraction effect. When the stirring claw rotates with the driving ring, it also helps that the stirring claw and the driving ring are basically at the same height of the mixing drum.

[0032] The driving mechanism for controlling the relative rotation of the driving ring and the mixing drum along the circumferential direction is connected to the control box 5 by signal, and the driving mechanism can be a friction wheel transmission mechanism, a gear transmission mechanism, a crank slider transmission mechanism, a belt transmission mechanism, etc. The present invention provides a specific structure of a driving mechanism 6, including a pair of friction wheels A61, a friction wheel B62, a transmission shaft 63, a guide column 64, an elastic telescopic member 65, an elastic pressing piece 66, and a thrust bearing 67. The friction wheel A61 is located above the upper surface of the end face 32, the transmission shaft 63 is fixed between the end face 32 and the friction wheel A61, the thrust bearing 67 and the guide column 64 are sequentially sleeved on the transmission shaft 63, a bearing 68 is arranged between the guide column 64 and the transmission shaft 63, a guide hole 42 is opened on the cantilever 41, and the guide column 64 is penetrated in the guide hole 4 2, a stop fit is formed between the guide hole 42 and the guide column 64, so that the drive ring is installed on the cantilever, one end of the elastic telescopic member 65 is connected and fixed to the bottom surface of the cantilever 41, and the other end is pressed against the upper surface of the end face 32, and can also be connected and fixed to the upper surface of the end face 32. The elastic telescopic member can be a spring and is sleeved on the guide column. The lower surface of the end face 32 is sequentially provided with a thrust bearing 67 and an elastic pressing plate 66. The friction wheel B62 is driven by a motor and installed on the base 4. The friction wheel B62 is connected to the friction wheel A61 by transmission, and the control box 5 is connected to the motor signal. When the drive ring is moved up and down, the drive ring, the transmission shaft, the guide rod, and the friction wheel A move up and down along the guide hole as a whole, and a space is provided below the drive ring to facilitate the placement of the mixing drum. The drive ring is released, and under the action of the elastic telescopic member, the friction wheel A is pressed against the friction wheel B, and the drive ring moves down accordingly. The thrust bearing and the elastic pressing plate apply pressure to the end cover of the mixing drum, pressing the mixing drum against the base. The rotation of friction wheel B drives friction wheel A to rotate. Since the guide column cannot rotate in the guide hole, the transmission shaft rotates with friction wheel A and drives the drive ring to rotate along the circumference of the mixing drum. The magnetic attraction of magnet A to magnet B drives the stirring claw to rotate in the mixing drum in the same direction as the drive ring.

[0033] The guide column can be designed as a rectangular column, and the shape of the guide hole matches it, thereby forming a non-rotation fit. When the transmission shaft rotates, the guide column can prevent wear due to self-rotation. The guide column can prevent wear caused by direct contact between the transmission shaft and the guide hole of the cantilever.

[0034] In order to improve the mixing effect of the stirring claws on the different components of the glue in the mixing drum, the driving ring rotates along the circumference of the mixing drum, and the mixing drum itself also rotates. The difference from the above structure is that a rotating shaft is set between the bottom of the mixing drum 1 and the base 4 to form a rotation connection, the mixing drum 1 can be driven by a motor, and the control box 5 is connected to the motor signal.

[0035] The control box 5 is provided with a power supply, a power switch, a display screen, operating buttons, etc., which are used to control the operation of the motor, the circumferential rotation speed, etc., and to set the stirring time, etc.

[0036] The inner and outer walls of the mixing drum can be coated with polytetrafluoroethylene, and the main body of the mixing head can be made of polytetrafluoroethylene to insulate, reduce friction resistance, and improve wear resistance. At the same time, the non-stickiness of polytetrafluoroethylene makes the mixing drum and the mixing head easy to clean.

[0037] The glue mixing device of the present invention mainly has the following advantages:

[0038] 1. The mixing head has realized non-contact transmission, and the mixing drum is completely closed. During the mixing process, the adhesive will not leak in the mixing drum.

[0039] 2. There is no mechanical connection between the stirring head and the mixing device as a whole. The stirring head and the mixing barrel can be completely separated and cleaned separately, which is easy to maintain.

[0040] 3. The device has a compact structure, flexible and convenient operation, easy loading and unloading of the mixing drum, and uniform mixing. The adhesive can be prepared and used according to production needs, and mixing drums of different volumes can be used according to the required material dosage. It is suitable for laboratories and production and manufacturing occasions with small product batches and a wide variety of products.

[0041] 4. Compared with manual mixing, it improves the stability of the mixing process, reduces process fluctuations caused by human factors, improves labor efficiency and reduces labor intensity.

[0042] 5. Compared with AB cartridge packaging, it reduces costs and reduces the generation of industrial solid waste.
