Description

Technical Field

[0001] The invention relates to the technical field of liquor koji production equipment, and in particular to a bionic compacting upper die and an operating method thereof. Background Art

[0002] Koji production is the core production link of the brewing industry, and further, koji block forming has become the core of the core. At present, the mechanized and automated koji production line is relatively mature, but the koji block forming process is not particularly ideal. Without considering the influence of the incoming materials, the demoulding of the compaction upper mold is a one-time full peeling mode, which will cause the upper mold to stick, resulting in a reduction in the total mass of the koji block, thus affecting the consistency and appearance of the koji block. The mold is seriously sticky and needs to be cleaned regularly to prevent the impact on subsequent compaction operations, thereby affecting production efficiency and increasing labor intensity. Therefore, the development of a compaction upper mold with bionic compaction and bionic demoulding can effectively improve the compaction quality and product appearance, reduce the possibility of sticking, and thus improve product quality, production efficiency, and reduce labor intensity. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a bionic compaction upper mold and an operation method thereof, which is not easy to stick to the material during the compaction and demoulding process, thereby facilitating the consistency and appearance of the curved block.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a bionic compaction upper mold, including a mold base, a mold cavity groove is provided at the bottom of the mold base, a diaphragm locking frame is provided at the bottom of the mold base, the diaphragm locking frame and the mold base are connected by bolts, the bionic diaphragm is pressed between the mold base and the diaphragm locking frame, the bionic diaphragm closes the mold cavity groove, and an air pressure balancing mechanism is provided on the upper side of the mold base for balancing the air pressure in the mold cavity groove.

[0005] In a preferred embodiment, the bionic membrane is made of elastic and flexible material.

[0006] In a preferred embodiment, the mold base and the diaphragm locking frame are matched through a stop structure, and the stop structure includes a convex stop and a concave stop, and the convex stop and the concave stop are respectively arranged on the bottom of the mold base and the upper side of the diaphragm locking frame, or the convex stop and the concave stop are respectively arranged on the upper side of the diaphragm locking frame and the bottom of the mold base.

[0007] In a preferred solution, the inner wall of the diaphragm locking frame is provided with an arcuate surface, and the arcuate surface and the mold cavity groove together form the mold cavity.

[0008] In a preferred solution, locking ribs are provided around the bionic diaphragm, and the locking ribs are annular structures and are arranged on the upper side and / or the lower side of the bionic diaphragm.

[0009] In a preferred solution, the air pressure balancing mechanism includes a vent disposed on the top of the mold base and connected to the mold cavity groove.

[0010] In a preferred embodiment, a breathing valve is provided in the vent.

[0011] The present invention also provides an operation method of a bionic compaction upper mold. When the material arranged in the lower mold is compacted, the bionic compaction upper mold moves downward and contacts the compacted material. The bionic diaphragm contacts the material and compacts the material. During the compaction process, the bionic diaphragm is squeezed and deformed toward the mold cavity groove, squeezing the air in the mold cavity groove and discharging it from an air pressure balance mechanism. When the bionic compaction upper mold moves upward for demoulding, air is replenished to the mold cavity groove from the air pressure balance mechanism to keep the pressure inside and outside the mold cavity groove balanced. The shape of the bionic diaphragm gradually returns to its original state, and the volume of the space between the mold cavity groove and the bionic diaphragm gradually increases. The bionic diaphragm is separated from the material in the order of first the four sides and then the middle, until the bionic compaction upper mold is completely separated from the material.

[0012] The bionic compaction upper die and the operation method thereof provided by the present invention have the following beneficial effects: 1. During production, the bionic compaction upper die moves downward and when it contacts the compacted material, its contact surface is made of flexible material that imitates the surface of limbs to reduce damage to the material; 2. During the compaction process, the air accumulated on the mold surface can be effectively discharged, reducing the negative impact of air entering deep into the material and causing lack of compaction uniformity; and during the demoulding process when the mold moves upward, due to the stickiness of the material and the presence of the bionic diaphragm and the breathing valve, the material is separated from the mold in a sequential peeling mode of first the four sides and then the middle, rather than a one-time peeling mode, thereby reducing the possibility of sticking to the mold.

[0013] 3. Through bionic compaction and bionic demoulding, the compaction quality and product appearance can be effectively improved, the possibility of sticking can be reduced, thereby improving product quality and production efficiency, reducing labor intensity, and obtaining better economic and social benefits.

DETAILED DESCRIPTION

[0015] Embodiment 1: like Figures 1 to 5 As shown, a bionic compaction upper die includes a die base 1, which is used to be connected to a corresponding driving mechanism, and the driving mechanism drives the bionic compaction upper die to move up and down, and a cylinder or a hydraulic cylinder can be selected. From a top view, the die base 1 can be a rectangular structure, a circular structure, or a polygonal structure.

[0016] The mold base 1 is provided with a mold cavity groove 101 at the bottom, and the shape of the mold cavity groove 101 is adapted to the shape of the upper surface of the curved block. The mold base 1 is provided with a diaphragm locking frame 3 at the bottom, and the diaphragm locking frame 3 and the mold base 1 are connected by bolts. The bionic diaphragm 2 is pressed around between the mold base 1 and the diaphragm locking frame 3. The bionic diaphragm 2 closes the mold cavity groove 101, that is, a cavity space is formed between the bionic diaphragm 2 and the mold cavity groove 101. During the compaction process, the bionic diaphragm 2 can be deformed toward the mold cavity groove 101 to form a flexible mold that imitates the sole of a human foot. The mold base 1 is provided with an air pressure balancing mechanism on the upper side, which is used for balancing the air pressure in the mold cavity groove 101.

[0017] The bionic membrane 2 is an elastic and flexible material with high elasticity, pressure resistance and high wear resistance, thereby reducing damage to the material, i.e., bionic compaction. In this embodiment, the bionic membrane 2 can be made of silicone, rubber or plastic, and specifically can be made of silicone rubber, natural rubber, synthetic natural rubber, styrene rubber, butadiene rubber, butyl rubber, nitrile rubber, ethylene propylene rubber, polyurethane rubber, fluororubber, etc.

[0018] The bionic membrane 2 is a planar plate-shaped structure. From a top view, the bionic membrane 2 can be a rectangular structure, a circular structure, or a polygonal structure.

[0019] Preferably, the bionic diaphragm 2 is provided with locking ribs 201 around it, which are annular structures and are arranged on the upper side or / and lower side of the bionic diaphragm 2. When the bionic diaphragm 2 is installed, the mold base 1 and the diaphragm locking frame 3 press the locking ribs 201, which is conducive to locking the bionic diaphragm 2.

[0020] Preferably, the inner wall of the diaphragm locking frame 3 is provided with an arc surface 301, and the arc surface 301 and the cavity groove 101 together form a cavity, and the size and shape of the cavity are adapted to the curved block. The bionic diaphragm 2 is arranged on the dividing plane between the arc surface 301 and the cavity groove 101, and is located in the middle of the cavity.

[0021] In this embodiment, the air pressure balance mechanism includes a vent 102 disposed on the top of the mold base 1 and connected to the mold cavity groove 101. The vent 102 is provided to help maintain the pressure balance between the cavity space formed between the bionic membrane 2 and the mold cavity groove 101 and the external environment, and reduce the negative impact of air entering deep into the material and causing lack of compaction uniformity.

[0022] Furthermore, a breathing valve 5 is provided in the vent 102. In a free state, the valve core of the breathing valve 5 is at the bottom, and the valve is open to maintain the balance of internal and external pressures.

[0023] During production, the bionic compaction upper mold moves downward, and when it comes into contact with the compacted material, its contact surface uses a bionic diaphragm 2 that imitates the surface of the limbs to reduce damage to the material; at the same time, during the compaction process, the air accumulated in the bionic diaphragm 2 and the mold cavity groove 101 can be effectively discharged, reducing the negative impact of lack of compaction uniformity caused by air entering deep into the material; and in the demolding process when the mold moves upward, due to the viscosity of the material and the presence of the bionic diaphragm 2 and the air pressure balance mechanism, the material is separated from the mold in a sequential peeling mode of first the four sides and then the middle, rather than a full peeling mode at once, thereby reducing the possibility of sticking to the mold.

[0024] Embodiment 2: Different from Example 1, Figure 5 As shown, the mold base 1 and the diaphragm locking frame 3 are matched through a stop structure 4, and the stop structure 4 includes a convex stop 401 and a concave stop 402, and the convex stop 401 and the concave stop 402 are respectively arranged on the bottom of the mold base 1 and the upper side of the diaphragm locking frame 3, or the convex stop 401 and the concave stop 402 are respectively arranged on the upper side of the diaphragm locking frame 3 and the bottom of the mold base 1.

[0025] In this embodiment, the convex stopper 401 is arranged on the upper side of the diaphragm locking frame 3 and is integrally arranged with the diaphragm locking frame 3. The concave stopper 402 is arranged at the bottom of the mold base 1 and is formed by a groove of the mold base 1. The convex stopper 401 and the concave stopper 402 are annular structures. Through the cooperation of the convex stopper 401 and the concave stopper 402, the "stopper" positioning assembly is realized, which is beneficial to the positioning and installation of the diaphragm locking frame 3.

[0026] Embodiment 3: The invention discloses an operation method of a bionic compacting upper die. When compacting a material arranged in a lower die, the bionic compacting upper die moves downward and contacts the compacted material. The bionic diaphragm 2 contacts the material and compacts the material. During the compacting process, the bionic diaphragm 2 is squeezed and deformed toward a cavity groove 101, and the air in the cavity groove 101 is squeezed and discharged from an air pressure balance mechanism. When the bionic compacting upper die moves upward for demoulding, air is added to the cavity groove 101 from the air pressure balance mechanism to keep the pressure inside and outside the cavity groove 101 balanced. The shape of the bionic diaphragm 2 gradually returns to its original state, and the volume of the space between the cavity groove 101 and the bionic diaphragm 2 gradually increases. The bionic diaphragm 2 is separated from the material in the order of first the surroundings and then the middle, until the bionic compacting upper die is completely separated from the material.

[0027] During production, the bionic compaction upper mold moves downward and when it comes into contact with the compacted material, its contact surface is made of flexible material that imitates the surface of limbs to reduce damage to the material. At the same time, during the compaction process, it can effectively discharge the air accumulated on the mold surface to reduce the negative impact of lack of compaction uniformity caused by air entering deep into the material. Moreover, during the demoulding process when the mold moves upward, due to the stickiness of the material and the presence of the bionic diaphragm and the breathing valve, the material is separated from the mold in a sequential peeling mode of first the four sides and then the middle, rather than a one-time peeling mode, thereby reducing the possibility of sticking to the mold.

[0028] Through bionic compaction and bionic demoulding, the compaction quality and product appearance can be effectively improved, the possibility of sticking can be reduced, and thus product quality and production efficiency can be improved, labor intensity can be reduced, and better economic and social benefits can be obtained.
