Description

Technical Field

[0001] The utility model relates to a manual grooving device, belonging to the field of cutting equipment. Background Art

[0002] In the current Pu'er tea market, compressed tea (such as tea cakes or tea bricks) is the mainstream. This type of tea has a longer aroma preservation time, better antioxidant properties, and is easy to preserve for a long time, making the tea easier to store and transport. However, this type of compressed tea is not very convenient for consumers in the process of making tea. Because the tea cake is very hard, it is not easy to cut into small pieces, which requires the use of tools such as tea knives or awls to cut longitudinally, but sometimes it breaks into small pieces, and the size of each cut cannot be guaranteed to be consistent. In addition, a large amount of tea residue will be produced, which is not only difficult to clean but also easy to hurt the hands, making tea making less easy. For this reason, it is necessary to propose grooving equipment.

[0053] Furthermore, the target object is a tea cake, and a tea cake pressing pin 36 is installed at one end of the rotating column 37 away from the supporting plate 31 .

[0054] Specifically, Figure 8 As shown, the target object moving and rotating device 4 includes a support plate 31, a sliding guide member ×432, a downward limit plate ×233, an M6×4 connecting screw 34, a displacement handle 35, and a target object rotating mechanism 45; wherein the target object rotating mechanism 45 is as shown in Fig.10 , 11 , 12. It is composed of a tea cake pressing nail × 536, a rotating column 37, a spring ball I 38, a limiting shaft sleeve 39, and a spring ball II 40. Fig. 9 As shown, the target object rotating mechanism 45 is placed at the center circular hole position on the support plate 31, and the circumferential array notches with a 90° interval cooperate with the spring ball II 40 extending from one end of the rotating column 37. The spring ball I 38 fixed at the other end of the rotating column 37 cooperates with three small circular holes with a 32mm interval on the chassis 44, and moves 32mm every time, thereby positioning the movement of the tea cake along the second preset direction; the tea cake rotates 90° to drive the spring ball II 40 in the target object rotating mechanism 45 to align with the notch and make a sound, thereby positioning the rotation angle of the tea cake; the tea cake pressing nail ×536 fixed on the rotating column 37 plays the role of fixing the tea cake. The tea cake pressing nail 36, the limiting shaft sleeve 39, the spring ball II 40 and the rotating column 37 are connected by threads. The limiting sleeve 39 can cooperate with the support plate 31 so that the target object rotating mechanism 45 will not move up and down (after the limiting sleeve 39 is installed from the bottom of the support plate 31 (the thick end of the limiting sleeve 39 cooperates with the limiting protrusion of the support plate 31), the rotating column 37 is connected to the limiting sleeve 39 (the thick end of the rotating column 37 contacts the top surface of the support plate), so as to achieve the limitation of the target object rotating mechanism 45 in the first preset direction). The sliding guide ×432 is connected to the bottom of the support plate 31 with M6 screws 34 to achieve the guidance of the target object moving and rotating device 4 in the second preset direction; the downward limiting plate ×233 is covered with a rubber layer, which has the function of buffering and vibration reduction. It is installed on both sides of the support plate 31 with M6 screws. There are notches on both sides that are colinear along the third preset direction to avoid collision when the knife body is pressed down; the displacement handle 35 is connected to the corresponding threaded hole of the support plate 31, which is used to push in and pull out the target object moving and rotating device 4. After the rotating column 37 is installed with the limiting sleeve 39, it cooperates with the opening on the support plate 31, so that the rotating column can rotate freely and has a limiting effect in the first preset direction (i.e. Fig.11 As the tea cake can be cut by rotation, multi-directional grooving can be achieved, and the second preset direction positioning and angle positioning are achieved by using two spring balls, thereby reducing the manufacturing cost of the mechanism.

[0055] like Figure 15-16As shown, the spline shaft 27 is connected to the frame 1 through a nut 46 and a sleeve 47, one end of the spline shaft 27 is slotted to cooperate with the inner hook of the spiral spring 48, and the outer ring of the spiral spring 48 will cooperate with the spiral spring fixing pin 8. When the pressing and cutting is completed, the spiral spring 48 will drive the spline shaft 27 to return. This not only ensures the safety of the pressing and cutting, but also saves the action of returning to the original position, making manual operation more convenient and quick.

[0056] It can be seen from the application of the above technical solution that the frame 1 serves as the framework of the entire pre-separator and plays the role of a connecting and supporting component. The connecting plate I7 ​​is connected to the chassis 44 with 6 M6 screws and is close to the frame baffle 42; the spline shaft 27 in the pressing device 2 passes through the spline connecting plate connection 10, so that the entire pressing device 2 is suspended at a fixed height and fixed to the frame 1 with two sleeves and nuts. The pressing connector III 26 is connected to the pressing mechanism connecting plate 18 with 4 M4 screws, so as to realize the movement of the pressing and cutting device 3 along the first preset direction (i.e. Figure 1 Up and down movement). The target object moving and rotating device 4 is placed on the base 5, and the sliding guide 32 passes through the slide groove on the chassis 44. Usage steps: Step 1, manually press the tea cake on the tea cake pressing pin 36, and then perform pressure cutting. After the pressure cutting is completed, the knife body 17 will automatically rise due to the spiral spring 48. Step 2, use the displacement handle 35 to move the support plate 31 to the next position for pressure cutting, and complete three-knife pressure cutting. Step 3, rotate the tea cake 180° to complete the parallel 6-knife pressure cutting. Step 4, rotate the tea cake 90°, repeat the above steps, and finally complete the 12-knife pressure cutting and remove the tea cake.

[0057] The specific description is as follows with reference to the accompanying drawings: Figure 18-20 As shown, Fig.18 The figure shows the initial position of the target object moving and rotating device 4. After the first cut is made at the position shown in the figure, the handle 30 is moved twice by 32 mm and cut (i.e., from Figures 18 to 20 Process), after three cuts, rotate the tea cake 180°, and then perform two 32mm displacements and press-cut the tea cake. At this time, 6 parallel indentations appear on the surface of the tea cake. Then rotate the tea cake 90°, repeat the above process, and complete 12 cuts (it is also possible to perform press-cutting every 90 degrees of rotation; or to achieve press-cutting through other rotation angles of the target object rotation mechanism 45 in the target object moving and rotating device and the movement along the second preset direction). During the press-cutting process, the M10 limit stud × 215 cooperates with the downward limit plate × 233 to prevent the cutter from continuing to press down at the preset position. Every time the tea cake moves 32mm and rotates 90°, the spring ball will make a sound and there will be resistance feedback. After each downward pressure, the volute spring 48 will drive the knife body 17 to return.

[0058] The specific implementation modes of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in the field without departing from the purpose of the present invention.
