Description

Technical Field

[0001] The utility model relates to the field of wine-making equipment, and in particular to a 3D printing device for sealing cellar mud. Background Art

[0002] Today, the liquor industry is developing very rapidly in all aspects, and the degree of automated production is changing with each passing day. Traditional cellar sealing production operations can no longer meet market demand, especially today when workers' labor intensity is reduced and production efficiency is increasingly sought. The new cellar sealing production model of Luzhou-flavor liquor that combines high-tech and traditional technologies has become a general trend. In recent years, liquor production has gradually developed in the direction of mechanization, intelligence, and informatization, and the degree of automation in brewing production has been relatively greatly improved.

[0003] The traditional cellar sealing process for the production of Luzhou-flavor liquor is to seal the cellar with mud, which seals the whole cellar and the cellar cap to isolate the air and complete the wine production and aroma fermentation process of the cellar. The traditional cellar sealing process is relatively complicated, and the tail water needs to be fully infiltrated with the cellar sealing mud. The cellar sealing mud is stepped on to be soft and mature, soft with hardness, wet but not thin, and the overall hardness, dryness and wetness are uniform, without hard lumps of dry mud or dripping thin mud in some parts. The traditional cellar sealing mud is stepped on entirely by hand with feet, and then the workers need to complete the cellar sealing by pressing the cellar sealing mud piece by piece, hitting the cellar cap with a wooden sling, and scraping and smoothing with mud palms. The thickness of the cellar sealing mud is controlled at 10-12cm. The entire cellar sealing process takes a long time and the workers have high labor intensity. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0020] like Figure 1 , Figure 2 As shown, the utility model is used for a 3D printing device for sealing mud, comprising a mud making mechanism 2 and a printing mechanism 1 connected by a mud guide tube 3; the mud making mechanism 2 comprises a guide tube 21 and a threaded rod 22 rotatably arranged in the guide tube 21, one end of the guide tube 21 is provided with a mud outlet 23 connected to the mud guide tube 3, and the other end is provided with a mud bucket 24 and a tailwater inlet 25 above, the threaded rod 22 is driven to rotate by a motor 26, and the sealing mud falling from the mud bucket 24 is pushed to the mud outlet 23; the printing mechanism 1 comprises a frame with a roller 13 at the bottom, a Z-axis slider 14 that can be vertically lifted along the frame, and a Y-axis guide rail 15 horizontally arranged on the Z-axis slider 14, and a nozzle 16 connected to the mud guide tube 3 is slidably arranged on the Y-axis guide rail 15. Among them, the threaded rod 22 adopts a threaded structure with a deep tooth groove, which is convenient for accommodating more sealing mud. The outer contour of the threaded rod 22 can contact the inner wall of the guide cylinder 21 or leave a certain gap, and the threaded rod 22 is rotatably connected to the end of the guide cylinder 21 through one end away from the mud outlet 23. The roller 13 at the bottom of the frame can move the frame along the X-axis, the Z-axis slider 14 moves along the Z-axis, and the nozzle 16 moves along the Y-axis, thereby flexibly adjusting the position of the nozzle 16 to meet the requirements of cellar sealing.

[0021] The specific process of using the utility model to seal the cellar is: first connect one end of the mud guide pipe 3 to the mud outlet 23, connect the tailwater pipe to the tailwater inlet 25, then put the cellar sealing mud into the mud bucket 24, and start the motor 26 at the same time to rotate the threaded rod 22 to mix the tailwater and the cellar sealing mud. The cellar sealing mud moves along the direction of the threaded rod 22 to mix and gradually become soft and mature. The mixed and mature cellar sealing mud enters the mud guide pipe 3 through the mud outlet 23 and reaches the nozzle 16. At this time, the printing structure 1 starts to operate, and the cellar sealing mud is sprayed out through the nozzle 16. The long strip of cellar sealing mud is spread on the trough surface along the X-axis and the Y-axis in turn. After covering the entire trough surface, the Z-axis slider 14 moves up to lay the second layer of cellar sealing mud, thereby completing the entire cellar sealing process. The multiple layers of cellar sealing mud will adhere to each other under the action of their own gravity to achieve a sealing effect. This cellar sealing device combines the traditional cellar sealing method with modern technology, greatly reduces the labor intensity of workers, improves the efficiency of cellar sealing, and can achieve assembly line cellar sealing.

[0022] For the mud making mechanism 2, the utility model also provides the following preferred solutions.

[0023] In order to ensure the stable operation of the mud making mechanism 2 , the mud making mechanism 2 further includes a bracket 27 , and the guide cylinder 21 and the motor 26 are both arranged on the bracket 27 .

[0024] In order to form continuous and dense strip-shaped cellar-sealing mud, the threaded rod 22 is arranged in the guide tube 21 at one end close to the mud bucket 24, the rear end of the threaded rod 22 is connected to the rotating shaft of the motor 26, and a compression area 28 is left between the front end of the threaded rod 22 and the end of the guide tube 21 close to the mud outlet 23. The cellar-sealing mud mixed and softened by the threaded rod 22 will first accumulate in the compression area 28 to form dense cellar-sealing mud, and then be pressed into the mud guide tube 3, thereby ensuring that the cellar-sealing mud in the mud guide tube 3 is continuous and dense.

[0025] In addition, the compression area 28 is connected to the mud outlet 23 via a conical transition surface 29. The conical transition surface 29 can further squeeze the cellar sealing mud and smoothly guide the cellar sealing mud into the mud guide pipe 3.

[0026] For the printing mechanism 1, the preferred solution of the utility model includes:

[0027] The frame is a door-shaped structure, including two columns 11 and a crossbeam 12. The bottoms of the two columns 11 are provided with rollers 13 that can roll along the X axis. The two ends of the Y-axis guide rail 15 are respectively provided with a Z-axis slider 14, and the two Z-axis sliders 14 are respectively slidably connected with the vertical slide grooves 17 on the two columns 11. The use of a door-shaped frame can ensure the stability of the frame operation. The width of the frame needs to exceed the width of the cellar to ensure that the movement range of the nozzle 16 can cover the entire cellar.

[0028] For the operation mode of each mechanism, manual control can be adopted, that is, the worker manually controls the movement of the frame, the lifting of the Z-axis slider 14 and the movement of the nozzle 16 on the Y-axis guide rail 15. Automated control can also be adopted, that is, the roller 13 is driven by a motor, the Z-axis slider 14 and the vertical slide 17 of the column 11 are driven to lift and lower by a gear rack elevator or a hydraulic rod, and the nozzle 16 is connected to the Y-axis guide rail 15 by a gear rack drive mechanism. The gear rack elevator and the gear rack drive mechanism are both realized by the gear on the rotating shaft of the motor installed on the Z-axis slider 14 or the nozzle 16 and the gear installed on the column 11 or the Y-axis guide rail 15. Of course, other existing mechanisms can also be used to achieve the same function. Cooperating with the controller to control the automatic operation of each mechanism and the motor 26 in the mud making mechanism 2, a fully automatic cellar sealing operation can be realized.

[0029] In order to better control the spraying direction of the cellar sealing mud, an angle-adjustable nozzle 18 may be provided below the nozzle 16. The cross-section of the nozzle 18 is a rectangular structure, so that the sprayed cellar sealing mud is in the shape of rectangular strips, which facilitates the adhesion of adjacent cellar sealing mud strips to each other and ensures the sealing effect.

[0030] Since the mud guiding tube 3 is filled with sealing mud, which is relatively heavy and needs to move with the movement of the frame, in order to avoid it being directly connected to the nozzle 16 and affecting the structural stability of the nozzle 16, the end of the mud guiding tube 3 connected to the printing mechanism 1 can be fixed on one of the Z-axis sliders 14, and then connected to the nozzle 16 through a telescopic hose, which can improve the convenience and stability of the movement of the nozzle 16.
