Description

Technical Field

[0001] This utility model relates to the field of coating production equipment technology, and in particular to a mixing and blending machine for coating production. Background Technology

[0002] Paint is a chemical material commonly used in construction, industry and other fields for decoration and rust prevention. Paint is a viscous liquid that is applied to the surface of an object to be protected or decorated and forms a continuous film that adheres firmly to the object. It is usually based on resin, oil or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared with organic solvents or water.

[0003] In the production process of coatings, a mixer is needed to mix and stir various raw materials. During the stirring process, additives need to be added to the coating or samples need to be taken from time to time. However, coating raw materials generally contain volatile and irritating gases. Even if the operators at the designated locations wear protective measures such as masks, gases can still escape during the process of opening the can, adding materials, and taking samples, causing inconvenience to other operators in the factory. Utility Model Content

[0004] In view of the above problems, this utility model provides a mixing and blending machine for paint production.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A mixing and blending machine for paint production is provided, including a mixing tank, a mixing mechanism installed inside the mixing tank, a tank cover installed on the top of the mixing tank, a feeding pipe vertically fixed on the tank cover, an opening at the top of the feeding pipe and a feed inlet at the bottom communicating with the mixing tank, a first sealing element installed inside the feed inlet for elastic sealing, a material holding cylinder movably installed inside the feeding pipe, an extension pipe cooperating with the feed inlet installed at the bottom of the material holding cylinder, a pipe cap detachably installed on the top of the feeding pipe, and a driving element installed on the pipe cap for driving the material holding cylinder to move inside the feeding pipe so that the extension pipe passes through the first sealing element.

[0007] Furthermore, the first sealing element includes a rubber sealing sheet, which is disposed inside the feed inlet and covers the feed inlet. A groove extending from the center to the edge is provided through the rubber sealing sheet, and multiple grooves are provided on the rubber sealing sheet.

[0008] Furthermore, the driving component includes a first threaded sleeve, which is fixedly mounted on the pipe cover and threadedly connected to the feeding pipe. An abutment ring is coaxially fixedly mounted on the end of the first threaded sleeve away from the pipe cover. When the pipe cover is threadedly connected to the feeding pipe through the first threaded sleeve, the abutment ring abuts against the end of the material container near the pipe cover and pushes the extension pipe through the first seal and into the mixing tank.

[0009] Furthermore, several connecting grooves are provided on the outer walls of both the material container and the extension pipe.

[0010] Furthermore, a spring is installed inside the feeding tube, which is used to push the material container away from the feed inlet.

[0011] Furthermore, a pusher screw is threadedly connected to the pipe cap. One end of the pusher screw, near the threaded sleeve, is coaxial with the extension tube of the material container and is fixedly connected to a stirring blade that can extend into the extension tube. The other end of the pusher screw is connected to a handle.

[0012] The beneficial effects of this utility model are as follows: When adding additives to the mixing tank, first open the pipe cover, seal the inlet of the feeding pipe with the rubber sealing sheet, add the additives into the holding cylinder, place the holding cylinder inside the feeding pipe, seal the feeding pipe with the pipe cover, and at the same time push the extension tube on the holding cylinder into the inlet, push open the rubber sealing sheet, and the additives can be smoothly added to the mixing tank. This can effectively reduce the escape of gas from the mixing tank and achieve a better environmental protection effect. Attached Figure Description

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] This application discloses a mixing and blending machine for paint production, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mixing tank 1, a tank cover 2 installed on the top of the mixing tank 1, and a mixing mechanism installed inside the mixing tank 1. The mixing mechanism can be a mixing rod driven by a motor. The mixing rod is rotatably installed on the tank cover 2 and extends into the mixing tank 1 to mix the materials in the mixing tank 1.

[0019] A feeding pipe 3 is vertically and integrally fixedly installed on the tank cover 2. The top of the feeding pipe 3 is open, and the bottom of the feeding pipe 3 is coaxially provided with an inlet 31 that connects the mixing tank 1 and the feeding pipe 3. A first sealing element that can elastically seal the inlet 31 is provided inside the inlet 31. Under normal conditions, the first sealing element seals the inlet 31, thereby allowing the gas in the mixing tank 1 to escape. A holding cylinder 4 is also movably installed inside the feeding pipe 3. The top opening and bottom of the holding cylinder 4 are coaxially and integrally connected to an extension pipe 41. The size of the extension pipe 41 should not be larger than the size of the inlet 31. When the holding cylinder 4 fits against the bottom wall of the feeding pipe 3, the extension pipe 41 can fit into the inlet 31 and open the first sealing element, so that the additive in the holding cylinder 4 can be smoothly added to the mixing tank 1. A cap 5 is detachably mounted on the top of the feeding pipe 3. The cap 5 has a drive mechanism for moving the container 4 within the feeding pipe 3 so that the extension tube 41 passes through the first seal. In actual use, the operator opens the cap 5, inserts the container 4 into the feeding pipe 3, aligns the extension tube 41 with the feed pipe without passing through the first seal, adds the desired additive into the container 4, and finally seals the feeding pipe 3 with the cap 5. The drive mechanism then moves the container 4 into the feeding pipe 3. Once the extension tube 41 passes through the first seal, the additive in the container 4 is added to the mixing tank 1, preventing gas from escaping from the mixing tank 1 during the additive addition process.

[0020] Specifically, the first sealing element includes a rubber sealing sheet 6, which is disposed inside the feed inlet 31 and covers the feed inlet 31. A groove 61 extending from the center to the edge is formed through the rubber sealing sheet 6, and multiple grooves 61 are provided on the rubber sealing sheet 6. Through the rubber sealing sheet 6 and the grooves 61, the rubber sealing sheet 6 can deform from the central groove 61 to form a channel through which the extension tube 41 can pass. After the extension tube 41 exits the feed inlet 31, the rubber sealing sheet 6 returns to its original shape, resealing the feed inlet 31.

[0021] The driving component can be a first threaded sleeve 51, which is fixedly mounted on the pipe cover 5. The first threaded sleeve 51 is threadedly connected to the feeding pipe 3. An abutment ring 52 is coaxially fixed at the end of the first threaded sleeve 51 away from the pipe cover 5. When the pipe cover 5 is threadedly connected to the feeding pipe 3 through the first threaded sleeve 51, the abutment ring 52 abuts against the end of the holding cylinder 4 near the pipe cover 5 and pushes the extension pipe 41 through the first seal and into the mixing tank 1. When the pipe cover 5 is connected to the feeding pipe 3 through the first threaded sleeve 51, the feeding pipe 3 can be closed, and at the same time, the first threaded sleeve 51 pushes the holding cylinder 4 to be completely embedded in the feeding pipe 3. The abutment ring 52 can increase the contact area with the holding cylinder 4, and can push the holding cylinder 4 to move more accurately.

[0022] Furthermore, several connecting grooves 42 are provided on the outer walls of both the material container 4 and the extension pipe 41. A notch corresponding to each connecting groove 42 is provided on the end face of the material container 4 away from the extension pipe 41. Through the connecting grooves 42, the internal air pressure of the material container 4 is the same as the air pressure inside the mixing tank 1 during its movement into the feeding pipe 3, facilitating the smooth entry of the additive into the mixing tank 1. Furthermore, a magnet can be installed inside the abutment ring 52. The abutment ring 52 is used to magnetically attract the material container 4. When the pipe cover 5 is removed, the magnetic attraction of the abutment ring 52 can be used to pull the material container 4 out of the central pipe.

[0023] Furthermore, a spring 32 is also installed inside the feeding pipe 3. The spring 32 is used to push the material container 4 away from the feed inlet 31. When the pipe cover 5 is removed, a greater thrust can be applied to push the extension pipe on the material container 4 out of the feed inlet 31, so as to close the feed inlet 31 in time and reduce the gas escape from the mixing tank 1.

[0024] Furthermore, a pusher screw 7 is threadedly connected to the pipe cap 5. One end of the pusher screw 7, near the threaded sleeve, is coaxially connected to the extension tube 41 of the material container 4 and fixedly connected to a stirring blade 71 that can extend into the extension tube 41. The other end of the pusher screw 7 is connected to a handle 72. After the pipe cap 5 closes the feed pipe, the operator can rotate the handle 72 to allow the pusher screw 7 and the stirring blade 71 to extend into the extension tube 41, quickly pushing the material in the material container 4 into the mixing tank 1. In this embodiment, the stirring blade 71 on the ejector screw is provided in multiple pieces and is dispersedly fixed on the pusher screw 7. For powder additives, by making the stirring blade 71 on the pusher screw 7 move back and forth at the extension tube 41, the powder is prevented from arching and blocking the extension tube 41.
