Description

Technical Field

[0001] The present application relates to the field of tea brick processing, and in particular to a high-precision pressing device for tea brick processing. Background Art

[0002] Tea brick is a traditional Chinese tea product, mainly made of Pu'er tea, and is made through a series of complex processes including screening, withering and fermentation, killing green tea, steaming, pressing, demoulding, drying, quality inspection, and packaging. The pressing uses high-precision pressing equipment to put the moistened tea leaves into the mold, and apply pressure mechanically or hydraulically to form it into a tea brick. After the pressing is completed, the tea brick is carefully taken out of the mold to avoid damage, and placed in a well-ventilated place to cool naturally and set.

[0003] The uniform and strong pressure of the existing high-precision pressing equipment is helpful to perfectly shape the tea bricks. However, after being pressed under strong pressure, a strong physical adhesion will be formed between the tea bricks and the mold, which will make subsequent demolding more difficult. If the demolding is forced, the initially pressed tea bricks will be damaged, affecting the output efficiency of the tea bricks. Increasing manual intervention in demolding will increase the labor cost. At the same time, due to certain differences in the strength and techniques of manual demolding, the shape, size and density of the demolded tea bricks will be different, affecting the standardization of the output tea bricks. In order to solve the above problems, a high-precision pressing device for tea brick processing is proposed.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-6 This application is described in further detail.

[0024] The present application embodiment discloses a high-precision pressing device for tea brick processing. Figure 1-6 The high-precision pressing device for processing tea bricks comprises a base 1, a movable plate 4 for supporting a lower mold 2 is arranged on the base 1, wedge-shaped grooves 25 are provided on both sides of the movable plate 4, wedge blocks 3 are arranged in the wedge-shaped grooves 25, the wedge blocks 3 and the movable plate 4 are wedge-matched, a support frame 5 is provided on the base 1, a high-precision pressing component for pressing tea leaves is provided on the support frame 5, a stopper 8 for releasing the wedge-shaped match between the wedge block 3 and the movable plate 4 is provided on the base 1, a lower pressing frame 11 for demoulding the lower mold 2 and an electric cylinder 2 10 for driving the lower pressing frame 11 are provided on the base 1, and a driving component 1 for driving the movable plate 4 to move horizontally is also provided on the base 1;

[0025] It should be noted that the inner size of the lower mold 2 is consistent with the size of the movable plate 4, the wedge block 3 is consistent with the smaller side size of the lower mold 2, the wedge block 3 is consistent with the size of the stopper 8, the two sides of the lower pressing frame 11 are consistent with the size of the stopper 8, and the bottom plate of the lower mold 2 is movable;

[0026] By adopting the above technical scheme, the driving component 1 drives the movable plate 4 and its upper and lower molds 2 to move under the high-precision pressing component. After the tea leaves in the lower mold 2 are pressed by the high-precision pressing component, the block 8 is continued to move to release the wedge-shaped fit between the wedge block 3 and the movable plate 4. The wedge block 3 no longer supports the lower mold 2. The pressed tea leaves have adhesion to the inner wall of the lower mold 2 and are not easy to fall off. The lower mold 2 is continued to be moved to the lower frame 11, and the electric cylinder 10 is started to make the lower pressing frame 11 press the smaller side of the lower mold 2 for smooth demoulding.

[0027] Reference Figure 1 The high-precision pressing assembly includes an electric cylinder 6 and an upper mold 7. The electric cylinder 6 is fixed on a support frame 5, and the telescopic end of the electric cylinder 6 is fixed to the upper mold 7;

[0028] It should be noted that the upper mold 7 cooperates with the lower mold 2;

[0029] It should be further explained that the electric cylinder 6 is driven by a servo motor, combined with high-precision encoder feedback, which can achieve precise control of the downward pressure and position, thereby achieving high-precision pressing of tea bricks, which is conducive to maintaining the consistency of density, thickness and shape of pressed tea bricks, and improving the quality of finished products. The model of the electric cylinder 6 can refer to the servo electric cylinder model YK135;

[0030] By adopting the above technical solution, the electric cylinder 6 is started to press the upper mold 7 downward to press the tea leaves in the lower mold 2, thereby achieving high-precision pressing of the tea bricks.

[0031] Reference Figure 2 A support frame 9 is provided on the base 1, an electric cylinder 10 is fixed on the support frame 9, a telescopic end of the electric cylinder 10 is fixed to a lower pressing frame 11, and an auxiliary demoulding component is provided on the lower pressing frame 11;

[0032] It should be noted that the description of the electric cylinder 2 10 can refer to the above-mentioned electric cylinder 1 6;

[0033] By adopting the above technical solution, when the lower mold 2 moves to the bottom of the lower pressing frame 11, the auxiliary demoulding component can be used to slightly knock the side wall of the lower mold 2 and then start the electric cylinder 2 10 to press the lower pressing frame 11 downward to achieve smooth demoulding.

[0034] Reference Figure 5The auxiliary demoulding component includes a mounting block 12, a rotating frame 13, a swing rod 14, a rubber pendulum 15, and a protrusion 18. The mounting block 12 is fixed on the lower pressing frame 11, the rotating frame 13 is fixed on the mounting block 12, one end of the swing rod 14 rotates on the rotating frame 13, the other end of the swing rod 14 is fixed to the rubber pendulum 15, one end of the protrusion 18 is fixed to the rubber pendulum 15, and the other end of the protrusion 18 is connected to the driving component 2. The driving component 2 includes a support block 16, a cam 17, a motor 19, and a spring 20. The support block 16 is fixed on the lower pressing frame 11, the support block 16 is located below the mounting block 12, the cam 17 rotates on the support block 16 through a rotating shaft, the motor 19 is fixed on the support block 16, the rotor end of the motor 19 is fixed to the rotating shaft on the cam 17, and the cam 17 is provided with a slide groove for the protrusion 18 to slide;

[0035] It should be noted that after the tea brick is formed under high pressure, there is an adsorption force between it and the lower mold 2. Direct pulling or prying with hard objects can easily cause damage to the edge or surface of the tea brick. The rubber pendulum 15 is soft in texture and can gently help the tea brick to separate from the lower mold 2 by tapping, thereby reducing damage to the integrity of the tea brick.

[0036] By adopting the above technical solution, when it is necessary to assist the lower pressure frame 11 to demold the lower mold 2, the motor 19 is started to rotate the cam 17, and the protrusion 18 slides along the slide groove opened on the cam 17, so that the rocker arm 14 drives the rubber pendulum 15 to knock the side wall of the lower mold 2, so that the demolding of the lower mold 2 is smoother.

[0037] Reference Figure 1 , 2 The driving component 1 includes a guide rod 21, a screw rod 22, and a motor 23. Two slide grooves are provided on the base 1. The guide rod 21 and the screw rod 22 are respectively arranged in the two slide grooves. The guide rod 21 is clearance-matched with the moving plate 4. The screw rod 22 is threadedly connected with the moving plate 4. The motor 23 is fixed on the base 1. The rotor end of the motor 23 is fixed to the screw rod 22.

[0038] It should be noted that the screw rod 22 rotates in one slide groove, and the guide rod 21 is fixed in another slide groove;

[0039] By adopting the above technical solution, when the movable plate 4 and its upper and lower molds 2 need to be moved, the motor 23 is started, and the screw rod 22 rotates under the guidance of the guide rod 21 to move the movable plate 4 and its upper and lower molds 2 along the slide groove on the base 1, thereby completing the pressing and demolding of the tea brick.

[0040] Reference Figure 1 , 3 The base 1 is provided with two sliding grooves, and electric push rods 24 are arranged in the two sliding grooves, and the telescopic ends of the electric push rods 24 are fixed to the wedge block 3;

[0041] By adopting the above technical scheme, the electric push rod 24 resets the wedge block 3. The electric push rod 24 is started to extend to push the wedge block 3 and the movable plate 4 to move together. When the wedge block 3 and the movable plate 4 move together to the bottom of the upper mold 7 and complete the pressing, the movable plate 4 continues to move under the drive of the motor 23. Under the restriction of the baffle 8, the wedge block 3 is released from the wedge-shaped fit with the movable plate 4. The electric push rod 24 is started again to contract, thereby driving the wedge block 3 to return to its initial position. When the movable plate 4 moves to the initial loading position, it can be wedge-fitted with the wedge block 3 again.
