Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a sliding sleeve mechanism of a tea stripping machine. Background Art

[0002] A tea leaf straightening machine is a mechanical equipment used to process green tea. It is mainly used to shape and straighten the tea leaves to make them tight and beautiful, while removing some excess fresh leaves to achieve the requirement of moderate spreading. Usually, a tea leaf straightening machine is composed of a pot body, a transmission system, a temperature control system, a conveying device, etc.

[0003] The sliding sleeve mechanism is one of the indispensable mechanisms in the transmission system of the strip straightening machine. The sliding sleeve mechanism can realize the processing of tea by reciprocating motion. The existing sliding sleeve mechanism is generally composed of a sliding rod, a sliding sleeve and a connecting plate. The connecting plate is directly welded to the outside of the sliding sleeve, and then connected to an external driving device to drive the sliding sleeve to move. The externally connected driving device applies force to the sliding sleeve to move it during driving, which can easily cause the sliding sleeve to deform and bite the sliding rod. At the same time, when the strip straightening machine is processed at high temperature, the externally connected equipment expands due to heat and drives the connecting plate to move, which also pulls the sliding sleeve to deflect a certain distance. As a result, the sliding sleeve and the sliding rod will be deformed, and sliding will be blocked, resulting in a short life of the sliding sleeve mechanism. Utility Model Content

[0020] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0021] The utility model discloses a sliding sleeve mechanism of a tea stripping machine. Figure 1 As shown, it includes a slide rod 2 and a slide sleeve 3, wherein the slide rod 2 is sleeved and slidably connected with the slide sleeve 3, wherein the slide rod 2 adopts a cylindrical structure, and a mounting plate 9 is fixed to the side of the slide sleeve 3, as shown in FIG. Figure 2 and 3 As shown, a mounting plate 9 is welded and fixed to the side of the sleeve 3, and the mounting plate 9 is fixed by welding in a rectangular structure, so as to ensure that the mounting plate 9 and the sleeve 3 are fixed more firmly and stably; limiting rods 8 are fixed on both sides of the mounting plate 9; the limiting rods 8 are provided with one or more groups, and a welding piece 7 is welded to the end of each group of the limiting rods 8; the limiting rods 8 are of a cylindrical structure, and the surface area of ​​the welding piece 7 is larger than the area of ​​the circular bottom surface of the limiting rods 8; illustratively, the limiting rods 8 are provided with three groups;

[0022] A buffer plate 4 is provided on the outside of the mounting plate 9, and there is a gap between the two; limiting holes 41 are provided on both sides of the buffer plate 4, the limiting rod 8 passes through the limiting holes 41, and the buffer plate 4 and the limiting rod 8 are rotatably and slidably connected; a welding piece 7 is welded on the end of the limiting rod 8 away from the mounting plate 9, and the welding piece 7 is used to limit the sliding of the buffer plate 4; the top of the buffer plate 4 is fixed with a connecting plate 5.

[0023] The side section of the buffer plate 4 adopts an inverted "U"-shaped structure, and the corners of the buffer plate 4 are chamfered to form an arc shape.

[0024] In order to facilitate the connection between the sliding sleeve mechanism and the outside, the connecting plate 5 adopts an "L"-shaped structure, and the connecting plate 5 is fixed to the buffer plate 4 by welding. The surface of the connecting plate 5 is provided with threaded holes for connecting with external equipment to drive the sliding sleeve mechanism to work;

[0025] In order to facilitate the installation of the entire sleeve processing, it also includes an outer protective box 1, and a slideway 13 with a "cross" shaped structure is opened on the surface of the outer protective box 1; through holes 12 are opened at both ends of the outer protective box 1, and the slide rod 2 passes through the through holes 12, and threaded structures are provided at both ends of the slide rod 2; the threaded structure is threadedly connected to the locking screw sleeve 6; fixed plates 11 are provided on both sides of the outer protective box 1, and fixed holes are opened on the surface of the fixed plates 11.

[0026] The sliding distance of the buffer plate 4 on the side of the limit rod 8 is 4-10 mm, and the width of the slide 13 is greater than the sliding distance of the buffer plate 4 on the side of the limit rod 8 to prevent the sliding mechanism from expanding due to heat during sliding, causing the buffer plate 4 and the connecting plate 5 to touch the outer protective box.

[0027] When the utility model is used, the overall installation and fixing is first performed, the mounting plate 9 is welded and fixed on the outer side of the sliding sleeve 3, and the limiting rods 8 are fixed on both sides of the mounting plate 9, so that the buffer plate 4 is sleeved on the outer side of the mounting plate 9, and the limiting rods 8 pass through the limiting holes 41, and then the welding piece 7 is formed by welding to limit the movement of the buffer plate 4; the sliding rod 2 passes through the through hole 12 and is locked by the locking screw sleeve 6 to complete the entire installation, such as Figure 4 shown.

[0028] When in use, as the tea stripping machine is started, the stripping machine drives the heated pot body to move back and forth, driving the sliding sleeve 3 on the surface of the sliding rod 2. Figure 1 As shown, the tea processing is completed by moving left and right. During processing, an external driving device connected to the connecting plate 5 applies force to the buffer plate 4. After the buffer plate 4 is subjected to the force, it will rotate along with the limit rod 8. For example, when the sleeve 3 is pushed to move to the left, the connecting plate 5 is pressed to move to the left to drive the sleeve 3 to move, avoiding direct action on the sleeve 3, causing the sleeve 3 to press the slide rod 2, causing the sleeve 3 to deform and the sliding to be blocked; when the sleeve mechanism expands at high temperature, the buffer plate 4 can move back and forth on the limit rod 8 to relieve the expansion.

[0029] The sliding sleeve mechanism of the utility model adds a combination of a buffer plate 4, a limit rod 8, and a mounting plate 9 between the sliding sleeve 3 and the connecting plate 5. The buffer plate 4 can rotate left and right and move forward and backward relative to the mounting plate 9; when the sliding sleeve 3 slides under the action of an external force, the external force acts on the connecting plate 5 to drive the buffer plate 4 to rotate, thereby preventing the sliding sleeve 3 from being deformed and gnawing at the sliding rod 2 due to the force applied to the sliding sleeve 3, thereby preventing the sliding of the sliding sleeve 3 from being obstructed; in addition, when the strip straightening machine is working, the external driving part is expanded due to high temperature, and the buffer plate 4 can buffer the expansion by moving a certain distance forward and backward on both sides of the mounting plate 9, thereby effectively avoiding damage to the sliding sleeve 3 and the sliding rod 2 caused by the force applied to the sliding sleeve 3 due to the expansion, thereby extending the overall service life.
