[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0025] See also Figures 1 to 3The utility model provides a discharging auxiliary device for coating production, which is connected to an extruder. The extruder includes a discharge pipe 1, including: a limit assembly 2 and a guide assembly 3. The limit assembly 2 includes a limit block 21, which is arranged above the discharge pipe 1 and has a guide notch 22 relative to the discharge pipe 1. The guide notch 22 is used to guide a mixing barrel 4 to slide in and align the discharge end of the mixing barrel 4 with the discharge pipe 1. The guide assembly 3 includes a guide barrel 31 and at least one linear drive member 32. One end of the guide barrel 31 is arranged relative to the discharge end of the mixing barrel 4, and the other end is slidably inserted in the discharge pipe 1. The linear drive member 32 is connected to the guide barrel 31, and is used to drive the guide barrel 31 to slide relative to the discharge pipe 1 to abut against the discharge end of the mixing barrel 4.

[0026] In this device, a limit block 21 is arranged above the discharge pipe 1 of the extruder, and a guide notch 22 is opened relative to the discharge pipe 1. The guide notch 22 is used to guide the mixing barrel 4 to slide in, and make the discharge end of the mixing barrel 4 after sliding in be aligned with the discharge pipe 1. At the same time, the guide barrel 31 can slide relative to the discharge pipe 1. Driven by the linear drive member 32, the guide barrel 31 can slide close to the discharge end of the mixing barrel 4, and the guide barrel after sliding is in contact with the discharge end of the mixing barrel 4.

[0027] Compared with the prior art, a limit block 21 with a guide notch 22 is provided above the feed tube 1 to guide the mixing barrel 4 to slide in and align the feed tube 1 with the discharge end of the mixing barrel 4, thereby facilitating the user to feed the material. At the same time, a guide barrel 31 structure that can slide relative to the feed tube 1 is utilized to reduce the gap between the feed tube 1 and the discharge end of the mixing barrel 4 by abutting the guide barrel 31 with the discharge end of the mixing barrel 4, thereby reducing leakage of materials and avoiding waste of materials. This can solve the technical problem in the prior art that it is difficult to ensure that the feed tube 1 of the mixing barrel 4 is aligned with the feed tube 1 of the discharge hopper when the mixed materials are fed into the extruder, thereby causing inconvenience in use.

[0028] Furthermore, in the present device, a discharge pipe 1 of the extruder is embedded in the floor of the second-floor platform 5, and the extruder also includes a barrel, and the discharge pipe 1 is arranged at the top of the barrel and is connected to the inside of the barrel, wherein the barrel is mounted in the space between the first floor and the second-floor platform 5. When discharge is required, the mixed mixing barrel 4 is transported to the second-floor platform 5, and the discharge end of the mixing barrel 4 is aligned with the discharge pipe 1, and the gravity of the material is used to automatically complete the discharge process. These are conventional settings well known to those skilled in the art and will not be described in detail.

[0029] Specifically, Figure 4 , Figure 5 As shown, the material guiding assembly 3 of the device further includes a fixing sleeve 33 , at least one sliding member 34 , an abutment block 35 , at least one elastic portion 36 , and a sealing gasket 37 .

[0030] The fixing sleeve 33 is coaxially arranged with the feeding pipe 1 and connected to the feeding pipe 1 , and one end of the material guiding cylinder 31 is inserted into the fixing sleeve 33 and slidably connected with the fixing sleeve 33 .

[0031] The setting of the fixing sleeve 33 plays a connecting and guiding role for the sliding of the material guiding cylinder 31 .

[0032] Furthermore, one end of the sliding member 34 is connected to the material guide cylinder 31, and the other end is slidably connected to the inner wall of the fixed sleeve 33. The sliding member 34 is used to connect and guide the sliding of the material guide cylinder 31 relative to the fixed sleeve 33; the abutment block 35 is annular, and the abutment block 35 is connected to the material guide cylinder 31, and overlaps the end of the fixed sleeve 33 away from the discharge pipe 1. The abutment block 35 is used to block the gap between the material guide cylinder 31 and the fixed sleeve 33 to reduce material leakage; the elastic part 36 is arranged between the fixed sleeve 33 and the abutment block 35, and is connected to the fixed sleeve 33. The elastic part 36 is used to play a buffering role when the abutment block 35 slides under the action of gravity when the action of the linear driving member 32 is released, so as to prevent the abutment block 35 from hitting the fixed sleeve 33; the sealing gasket 37 is arranged relative to the discharge pipe 1 and is connected to the abutment block 35. The sealing gasket 37 abuts against both the abutment block 35 and the material discharging end of the mixing barrel 4 to fill the gap between the abutment block 35 and the material discharging end of the mixing barrel 4 to reduce material leakage.

[0033] As an implementation method, Figures 1 to 3 As shown, the limit block 21 is U-shaped, and the opening of the limit block 21 forms a guide notch 22 . The limit assembly 2 also includes at least one support column 23 , which is connected to the limit block 21 for supporting the limit block 21 .

[0034] The support column 23 supports and connects the connection between the limit block 21 and the second-layer platform 5. The U-shaped limit block 21 can not only guide the mixing barrel 4 to slide into the guide notch 22, but also limit the mixing barrel 4 from continuing to slide relative to the guide notch 22, thereby ensuring that the discharge end of the feeding pipe 1 is aligned with the discharge end of the mixing barrel 4, which not only facilitates the user's operation, but also effectively reduces the waste of materials.

[0035] As another implementation method, Figure 1 , Figure 2 As shown, the cross-sectional area of ​​the opening end of the guide notch 22 gradually decreases along the opening direction, and guide slopes are formed on opposite sides of the guide notch 22 .

[0036] The guide notch 22 gradually increases in size along its opening direction, which facilitates the user to slide the mixing barrel 4 into the guide notch 22. The position of the mixing barrel 4 can be adjusted by the gradually changing guide notch 22 to ensure that the feed tube 1 is aligned with the discharge end of the mixing barrel 4, which is convenient for use.

[0037] As another implementation method, Figure 1 , Figure 2 As shown, the limiting assembly 2 further includes at least one buffer portion 24 , which is disposed opposite to the opening end of the guide notch 22 and connected to the limiting block 21 .

[0038] The buffer portion 24 is arranged relative to the open end of the guide notch 22 and is connected to the limit block 21, so as to reduce the deviation caused by the collision between the mixing barrel 4 and the limit block 21 after the mixing barrel 4 slides in. It can not only extend the service life, but also limit the sliding of the mixing barrel 4, and can effectively ensure that the feeding pipe 1 is aligned with the discharge end of the mixing barrel 4, which is convenient for use.

[0039] Furthermore, the buffer part 24 in the present device is a buffer pad block that is common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0040] like Figure 1 As shown, the device further comprises an auxiliary component 6 , and the auxiliary component 6 comprises a striking piece 61 and an auxiliary staircase 62 .

[0041] The knocking member 61 includes a knocking rod 611 , which is disposed on one side of the limiting block 21 and is used for knocking the mixing barrel 4 to assist in material discharge.

[0042] The user can knock the mixing barrel 4 with the knocking rod 611 to shake off the materials attached to the inner wall of the mixing barrel 4, thereby reducing the waste of materials.

[0043] As an implementation method, Figure 1 As shown, the knocking member 61 further includes a fixing frame 612 , which is disposed on one side of the limiting block 21 and connected to the limiting block 21 , and the knocking rod 611 is detachably connected to the fixing frame 612 .

[0044] The fixing frame 612 is used to place the knocking rod 611 and supports the knocking rod 611 .

[0045] As another implementation method, Figure 1 As shown, the knock rod 611 has a through hole, and the knock member 61 also includes a hook 613, which is connected to the fixing frame 612 and extends in a direction perpendicular to the fixing frame 612. The knock rod 611 is detachably connected to the hook 613 through the through hole.

[0046] The knocking rod 611 can be conveniently connected to the fixing frame 612 through the hook 613, and can also be conveniently removed.

[0047] As an implementation method, Figure 1As shown, the knocking member 61 further includes a connecting ring 614 . The connecting ring 614 is provided with a through hole. The connecting ring 614 is connected to the knocking rod 611 and is detachably connected to the hook 613 .

[0048] The connecting ring 614 is matched with the hook 613 to make it more convenient for the user to take the knocking rod 611 and connect the knocking rod 611.

[0049] As another implementation method, Figures 1 to 3 As shown, the auxiliary staircase 62 is arranged on one side of the limiting block 21 and extends in a direction close to the feeding pipe 1 .

[0050] The auxiliary staircase 62 can facilitate the user to stand at a high place to observe the situation in the mixing barrel 4, and at the same time facilitate the user to knock the mixing barrel 4 to reduce the waste of materials.

[0051] Furthermore, the auxiliary staircase 62 here is a step staircase that is common and easy to purchase on the market. The step staircase is arranged on one side of the discharge pipe 1 and is connected to the second-floor platform 5. This is a conventional setting well known to technical personnel in this field and will not be elaborated on.

[0052] In the specific working process of the utility model, the limit block 21 is arranged above the discharge pipe 1 of the extruder, and a guide notch 22 is opened relative to the discharge pipe 1. The guide notch 22 is used to guide the mixing barrel 4 to slide in, and make the discharge end of the mixing barrel 4 after sliding in be aligned with the discharge pipe 1. At the same time, the guide barrel 31 can slide relative to the discharge pipe 1. Driven by the linear drive member 32, the guide barrel 31 can slide close to the discharge end of the mixing barrel 4, and the guide barrel after sliding is in contact with the discharge end of the mixing barrel 4. Compared with the prior art, a limit block 21 with a guide notch 22 is provided above the feed tube 1 to guide the mixing barrel 4 to slide in and align the feed tube 1 with the discharge end of the mixing barrel 4, thereby facilitating the user to feed the materials. At the same time, a guide barrel 31 structure that can slide relative to the feed tube 1 is utilized to reduce the gap between the feed tube 1 and the discharge end of the mixing barrel 4 by abutting the guide barrel 31 with the discharge end of the mixing barrel 4, thereby reducing leakage of materials and avoiding waste of materials.

[0053] When in use, the user first transports the mixing barrel 4 to the second-layer platform 5, and then slides the mixing barrel 4 into the guide notch 22. During the sliding process, the guide notch 22 automatically guides the discharge end of the mixing barrel 4 to be aligned with the discharge tube 1, and then the linear drive member 32 drives the guide barrel 31 to slide relative to the discharge tube 1, so that the sliding guide barrel 31 abuts against the discharge end of the mixing barrel 4, and finally opens the discharge end of the mixing barrel 4, and the material falls into the discharge tube 1 of the extruder through the discharge end of the mixing barrel 4. As the material is continuously discharged, the user can reduce the adhesion of the material to the inner wall of the mixing barrel 4 by knocking the rod 611, thereby reducing the waste of material.

[0054] Furthermore, after the material discharge is completed, the discharging end of the mixing barrel 4 is closed and the linear drive member 32 is driven to retract. After the guide barrel 31 is separated from the discharging end of the mixing barrel 4 , the mixing barrel 4 can be slid out of the guide notch 22 .

[0055] The device, through the above structure, can solve the technical problem in the prior art that it is difficult to ensure that the feed pipe 1 of the mixing barrel 4 is aligned with the feed pipe 1 of the feed hopper when the mixed material is fed into the feed hopper of the extruder, thus causing inconvenience in use.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
