[0011] A driving motor is used to drive the deblocking driving shaft to rotate.

[0012] Furthermore, the deblocking fixing frame is arranged tilted.

[0013] Furthermore, one end of the second block-solving blade, the third block-solving blade and the fourth block-solving blade protruding from the rectangular tube is provided with a triangular protrusion.

[0014] Furthermore, one end of the first block-deblocking blade protruding from the rectangular tube is provided with an end chamfered surface.

[0022] (1) When the fermented Pu'er tea block material falls onto the deblocking fixed blade on the deblocking fixed frame, the driving motor drives the deblocking driving shaft to rotate, and the deblocking blade group rotates accordingly. The first oblique cutting surface on the first deblocking blade cuts the Pu'er tea block material, and the protruding rectangular tubes of the second, third and fourth deblocking blades can play the role of stirring, breaking and pushing the Pu'er tea block material above. The cut Pu'er tea will fall from the gap between the deblocking blade group and the adjacent deblocking fixed blade. The cutting effect is good by adopting this method.

[0023] (2) Under the action of the first deblocking blade, the second deblocking blade, the third deblocking blade, the fourth deblocking blade and the fixed deblocking blade, the block-shaped Pu'er tea passes through a 0.85 cm gap after cutting, thus achieving cutting and deblocking. Unagglomerated Pu'er tea in the form of strips can pass through the gap without breaking and affecting the appearance quality, and the breakage rate of Pu'er tea is low;

[0024] (3) When the Pu'er tea blocks are cut, due to its resistance, the polyethylene flexible polymer material layer can play a good role in shock absorption. During the cutting process, the blade on the rotating shaft of the deblocking device can perform phased linear unidirectional flexible cutting on the Pu'er tea material, which can provide buffering and avoid damaging the top-quality, high-value large-leaf ancient tree tea leaves.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 7 The present invention provides a technical solution for a Pu'er tea deblocking device.

[0035] A Pu'er tea deblocking device, comprising:

[0036] A deblocking box 1, a deblocking cavity 21 is provided in the deblocking box 1, and a deblocking inlet 2 and a deblocking outlet 3 are provided on the deblocking cavity 21;

[0037] A deblocking fixed frame 4, the deblocking fixed frame 4 is fixed in the deblocking cavity 21, the deblocking fixed frame 4 is provided with a deblocking fixed groove 5, a plurality of parallel deblocking fixed blades 6 are fixed in the deblocking fixed groove 5, the deblocking fixed blades 6 are provided with deblocking fixed blade edges 7, and the deblocking fixed blade edges 7 face the deblocking inlet 2;

[0038] A deblocking drive shaft 8, which is arranged below the deblocking fixed frame 4, is rotatably connected to the deblocking box 1, and a rectangular tube 9 is installed on the deblocking drive shaft 8;

[0039] A plurality of deblocking blade groups 22, the deblocking blade groups 22 are arranged in sequence along the length direction of the rectangular tube 9, the deblocking blade groups 22 are sequentially arranged between adjacent deblocking fixed blades 6, there is a gap between the deblocking blade groups 22 and the adjacent deblocking fixed blades 6, the deblocking blade groups 22 include a first deblocking blade 10, a second deblocking blade 11, a third deblocking blade 12 and a fourth deblocking blade 13, the first deblocking blade 10, the second deblocking blade 11, the third deblocking blade 12 and the fourth deblocking blade 13 are sequentially fixed on four sides of the rectangular tube 9, the first deblocking blade 10, the second deblocking blade 11, the third deblocking blade 12 and the fourth deblocking blade 13 protrude from the side of the rectangular tube 9 by T1, T2, T3 and T4 respectively, T1 has the largest length, T2 and T4 are equal, T3 is greater than T2 and T4, and the first deblocking blade 10 is provided with a first chamfered surface 14;

[0040] The driving motor 15 is used to drive the deblocking driving shaft 8 to rotate.

[0041] When the fermented Pu'er tea block material falls onto the deblocking fixed blade 6 on the deblocking fixed frame 4, the driving motor 15 drives the deblocking driving shaft 8 to rotate, and the deblocking blade group 22 rotates accordingly, and the first beveled surface 14 on the first deblocking blade 10 cuts the Pu'er tea block material, and the second deblocking blade 11, the third deblocking blade 12 and the fourth deblocking blade 13 protrude from the rectangular tube 9. One end of the protruding rectangular tube 9 can play the role of stirring, breaking and pushing the Pu'er tea block material above. The cut Pu'er tea will fall from the gap between the deblocking blade group 22 and the adjacent deblocking fixed blade 6, and the unagglomerated Pu'er tea in strips and the like can pass through the gap without breaking and affecting the appearance quality.

[0042] The deblocking fixed frame 4 is tilted, and the tilt angle is preferably 45°. The angle between the first deblocking blades 10 of adjacent deblocking blade groups 22 is 90°. The gap between the deblocking blade group 22 and the adjacent deblocking fixed blade 6 is 0.85 cm. The thickness of the first deblocking blade 10, the second deblocking blade 11, the third deblocking blade 12 and the fourth deblocking blade 13 are all 1.8 cm, and the thickness of the deblocking fixed blade 6 is 1.7 cm.

[0043] When the fermented Pu'er tea block material falls onto the deblocking fixed blade 6 on the deblocking fixed frame 4, the driving motor 15 drives the deblocking driving shaft 8 to rotate, and the deblocking blade group 22 rotates accordingly, and the first beveled surface 14 on one of the first deblocking blades 10 cuts the Pu'er tea block material. Since the angle between the first deblocking blades 10 of adjacent deblocking blade groups 22 is 90°, after the deblocking driving shaft 8 rotates 90°, the first beveled surface 14 of the other first deblocking blade 10 cuts the Pu'er tea block material, and the cutting is cyclically carried out. During the cutting process, since T3 is greater than T2 and T4, the second deblocking blade 11, the third deblocking blade 12 and the fourth deblocking blade 13 of each layer in this process stir the Pu'er tea block materials accumulated on the deblocking fixed frame 4 inclined at 45°, and can also break and push them to the lower part of the fixed frame, thereby increasing the deblocking efficiency.

[0044] Under the action of the first deblocking blade 10, the second deblocking blade 11, the third deblocking blade 12, the fourth deblocking blade 13 and the fixed deblocking blade 6, the block Pu'er tea passes through a 0.85 cm gap after cutting to achieve cutting and deblocking. During the first to fifth fermentation processes of its sun-dried green tea, the moisture content of the raw Pu'er tea is relatively high, and the raw tea is highly soft. It appears in block shape because the substances produced by microbial fermentation make the tea combine with water to form blocks. Therefore, the present scheme can deblock the blocks, and the unagglomerated Pu'er tea in strips and the like can pass through the gaps without breaking and affecting the appearance quality, and the breakage rate of Pu'er tea is relatively low.

[0045] like Figure 4 and Figure 5 As shown, the second block cutting blade 11, the third block cutting blade 12 and the fourth block cutting blade 13 are all provided with a triangular protrusion 16 at one end protruding from the rectangular tube 9, and a chamfer is provided on the triangular protrusion 16. The first block cutting blade 10 is provided with an end chamfer 17 at one end protruding from the rectangular tube 9.

[0046] like Figure 6 and Figure 7 As shown, two rectangular frames 18 are fixed on the deblocking drive shaft 8, and a retaining ring 19 is fixed on the rectangular frame 18. The two ends of the rectangular tube 9 are sleeved on the two rectangular frames 18, and the rectangular tube 9 is located between the two retaining rings 19. The outer wall of the rectangular frame 18 is provided with a polyethylene flexible polymer material layer.

[0047] When cutting Pu'er tea blocks, there will be resistance, and the polyethylene flexible polymer material layer can play a good role in shock absorption. The polyethylene flexible polymer material layer has a high elastic modulus and good elastic recovery. It absorbs and disperses energy under the action of external force, and alleviates the sudden force caused by external impact through its own softness and elasticity. It can undergo plastic deformation under the action of external force, absorb and disperse energy, and thus reduce the conduction of impact force. It has high fracture toughness and strength, can effectively absorb impact energy, reduce vibration and damage of structures or equipment, has good wear resistance, and can reduce surface wear and damage under the action of friction and collision. It can effectively extend the service life of structures or equipment and reduce the frequency of maintenance and replacement.

[0048] In the traditional deblocking machine, the hard block Pu'er tea material is directly deblocked rigidly, which damages the top-grade, high-value large-leaf ancient tree tea leaves. With this deblocking machine design, the blade on the rotating shaft of the deblocking device can perform phased linear unidirectional flexible cutting on the Pu'er tea material during the cutting process, which can be buffered. The above design is used for the deblocking process after the fermentation of premium large-leaf ancient tree tea leaves. It needs to deblock a large number of fresh Pu'er tea leaves from ecological tea gardens after fermentation. Because the fresh leaves are larger than the premium large-leaf ancient tree tea leaves, the deblocking fixed blade 6 of the deblocking fixed frame 4 directly "takes one by one" to achieve rapid and large-scale deblocking.

[0049] like Figure 1 As shown, the deblocking device further includes an upper outer material frame 20, the upper end of which is larger than the lower end, the lower end of which is fixedly connected to the upper end of the deblocking box 1, and the upper outer material frame 20 is connected to the deblocking cavity 21. The upper end of the upper outer material frame 20 receives the Pu'er tea blocks to be deblocked, and then transports them to the deblocking box 1 through the lower end.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
