Description

Technical Field

[0001] This utility model relates to the field of adhesive raw material mixers, specifically a dustproof mechanism for adhesive raw material mixers. Background Technology

[0002] Adhesive raw material mixers are specialized equipment used for mixing and stirring adhesive raw materials. They include various types such as planetary mixers, ribbon mixers, and horizontal mixers, suitable for adhesive raw materials of different viscosities and properties. Typically, they utilize the rapid rotation of components such as screws, blades, or agitators to lift the raw material from the bottom to the top of the container, then scatter it in an umbrella-like pattern back to the bottom, achieving a rolling and stirring process. They are widely used in industries such as chemicals, building materials, and coatings for mixing and stirring various adhesive raw materials, such as adhesives, putty, and silicone sealants.

[0003] In the traditional adhesive preparation process, the raw material mixture needs to be mixed in a mixer. However, during the mixing process, powdery materials are easily scattered from the mixing port of the mixer, causing dust pollution to the surrounding environment. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a dustproof mechanism for an adhesive raw material mixer. This solves the technical problem that in the current adhesive preparation process, the raw material mixture needs to be mixed in a mixer, but during the mixing process, powdery materials are easily scattered from the mixing port of the mixer, causing dust pollution to the surrounding environment.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a dustproof mechanism for an adhesive raw material mixer is designed, including a mixing drum, a feed pipe connected to the middle of the top of the mixing drum, the feed pipe having a hollow structure, a dust suction hole opened inside the feed pipe, a baffle installed on the inner wall of the feed pipe, an air suction hole opened at one end of the outer side of the feed pipe, a dust suction pipe connected to one end of the outer side of the air suction hole, a guide tube connected to the bottom of the dust suction pipe, a through hole opened at one end of the outer side of the guide tube, a negative pressure pump installed at one end of the outer side of the through hole, and a filter screen installed in the inner cavity of the through hole.

[0006] Preferably, the bottom of the conduit is connected to a circular tube, one end of which is connected to a feed pipe. A pusher column is slidably connected inside the circular tube, and a rectangular hole is opened on the pusher column. A T-shaped push rod is movably passed through the end of the circular tube away from the feed pipe, and the T-shaped push rod is connected to the pusher column.

[0007] Preferably, a sealing gasket is fixedly connected to the outer side of the pusher column, and the sealing gasket is elastic.

[0008] Preferably, one end of the filter screen is on the same vertical plane as the inner wall of the conduit.

[0009] Preferably, a spring is sleeved on the outside of the T-shaped push rod on the outer side of the round tube, and the two ends of the spring are respectively connected to the T-shaped insert rod and the round tube.

[0010] Preferably, the spring is always in a compressed state, and the spring force is greater than the frictional force between the pusher and the round tube.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This utility model combines a mixing drum, a feed pipe, a baffle pipe, a dust suction hole, an air suction hole, a guide pipe, a dust suction pipe, a negative pressure pump, a through hole, a filter screen, a round tube, a T-shaped push rod, a push column, and a rectangular hole. When the mixing drum is working to stir the material, the negative pressure pump is activated to generate negative pressure in the guide pipe. This, in conjunction with the filter screen, draws the dust generated during the mixing drum's operation into the guide pipe through the dust suction hole, thus preventing powdery materials from escaping from the feed pipe of the mixing drum and causing dust pollution to the surrounding environment. Furthermore, when the negative pressure pump stops working, the dust adsorbed on the surface of the filter screen falls into the rectangular hole due to gravity. Then, the T-shaped push rod pushes the push column to move, placing the dust collected in the rectangular hole into the mixing drum, thereby enabling the collection of dust and avoiding waste.

[0013] 2. This utility model increases the sealing performance of the connection between the pusher column and the inner wall of the round tube by setting a sealing gasket. This not only prevents the powder in the mixing drum from being sucked into the guide tube when the negative pressure pump is started, but also prevents the dust collected in the rectangular hole from remaining in the round tube when the pusher column moves.

[0014] 3. This utility model uses a spring. When the T-shaped push rod is pushed, the spring is compressed, so that the dust collected in the rectangular hole is placed in the mixing drum. When the hand releases the T-shaped push rod, the spring force pushes the T-shaped push rod and the push column to reset, which facilitates the subsequent use of the push column.

[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A dustproof mechanism for an adhesive raw material mixer, see [link to example]. Figures 1 to 4 The system includes a mixing drum 1, with a feed pipe 11 connected to the top center of the mixing drum 1. The feed pipe 11 is hollow and has a dust suction hole 21 inside. A baffle 2 is installed on the inner wall of the feed pipe 11. An air suction hole 22 is opened at one end of the feed pipe 11, and a dust suction pipe 31 is connected to the outer end of the air suction hole 22. A guide pipe 3 is connected to the bottom of the dust suction pipe 31, and a through hole 33 is opened at one end of the outer end of the guide pipe 3. A negative pressure pump 32 is installed at the outer end of the through hole 33. A filter screen 34 is installed inside the through hole 33, and one end of the filter screen 34 is on the same vertical plane as the inner wall of the guide pipe 3. A circular pipe 4 is connected to the bottom of the guide pipe 3, and one end of the circular pipe 4 is connected to the feed pipe 11. A pusher column 42 is slidably connected inside the circular pipe 4. A rectangular hole 43 is provided on the column 42. A T-shaped push rod 41 is movably inserted through the end of the round tube 4 away from the feed pipe 11, and the T-shaped push rod 41 is connected to the push column 42. During operation, when the mixing drum 1 is working to stir the material, the negative pressure pump 32 is started to generate negative pressure in the guide tube 3. This, together with the filter screen 34, sucks the dust generated by the mixing drum 1 during operation into the guide tube 3 through the dust suction hole 21, thereby preventing the powdery material from being scattered from the feed pipe 11 of the mixing drum 1 and causing dust pollution to the surrounding environment. When the negative pressure pump 32 stops working, the dust adsorbed on the surface of the filter screen 34 falls into the rectangular hole 43 due to gravity. Then, the push column 42 is moved by the T-shaped push rod 41 to place the dust collected in the rectangular hole 43 into the mixing drum 1, thereby enabling the collection of dust to be utilized and avoiding waste.

[0022] For details, see Figure 3 A sealing gasket 44 is fixedly connected to the outside of the pusher column 42, and the sealing gasket 44 is elastic. By setting the sealing gasket 44, the sealing performance of the connection between the pusher column 42 and the inner wall of the round tube 4 is increased. This not only prevents the powder in the mixing drum 1 from being sucked into the conduit 3 when the negative pressure pump 32 is started, but also prevents the dust collected in the rectangular hole 43 from remaining in the round tube 4 when the pusher column 42 moves.

[0023] Further, see Figure 2A spring 45 is sleeved on the outside of the T-shaped push rod 41 on the outside of the round tube 4. The two ends of the spring 45 are connected to the T-shaped insert rod and the round tube 4 respectively. The spring 45 is always in a compressed state, and the elastic force of the spring 45 is greater than the frictional force between the push column 42 and the round tube 4. When the T-shaped push rod 41 is pushed, the spring 45 is compressed, so that the dust collected in the rectangular hole 43 is placed in the mixing drum 1. When the hand releases the T-shaped push rod 41, the elastic force of the spring 45 pushes the T-shaped push rod 41 and the push column 42 to reset, which facilitates the subsequent use of the push column 42.
