Description
Technical Field
[0001] This invention relates to the field of tea brick production technology, and in particular to a tea-cutting machine. Background Technology
[0002] Tea bricks are tea leaves shaped like bricks. They are a representative type of compressed tea, made from tea leaves, tea stems, and sometimes tea dust pressed into blocks. To facilitate storage and transportation, or according to customer habits, tea leaves are pressed into square tea bricks of different sizes, making packaging, storage, and transportation convenient.
[0003] To facilitate the carrying and daily brewing of tea bricks, molds (such as...) are used. Figure 4 (As shown) Press the tea bricks into small pieces (such as...) Figure 5 As shown in the image, the pressed tea bricks are then cut into smaller pieces (each piece is 24mm long and wide, and 14mm deep). However, since there are no suitable cutting machines on the market, the small tea bricks need to be cut manually, resulting in high production costs. Summary of the Invention
[0004] The purpose of this invention is to provide a tea-cutting machine, which aims to solve the problem of high production costs caused by the need for manual cutting of small tea bricks.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a tea-cutting machine, comprising a machine body, a drive cylinder disposed on the top of the machine body, and a pusher plate disposed horizontally at the output end of the drive cylinder. The bottom surface of the pusher plate is uniformly provided with a plurality of pusher components with square cross-sections along the vertical direction, and a predetermined distance is provided between adjacent pusher components. A discharge plate is disposed horizontally on the machine body, and a plurality of discharge holes corresponding one-to-one with the pusher components are opened vertically on the discharge plate. The pusher components are movably fitted against the inner wall of the discharge holes. A pressure plate is movably disposed horizontally on the machine body, located between the discharge plate and the pusher components. The pressure plate is provided with a plurality of pressure holes corresponding one-to-one with the discharge holes. The pusher components are movably fitted against the inner wall of the pressure holes, and the pusher components can drive the pressure plate to rise and fall.
[0006] The above technical solution is used to process pressed tea bricks (such as...) Figure 5As shown, during shearing, the tea brick is laid flat on the discharge plate, with the convex side facing down and the flat side facing up in the discharge hole. Then, the drive cylinder is activated, driving the pusher plate and pusher components downwards. As the pusher components move downwards, the pressure holes on the pressure plate are against the outer wall of the pusher components. Through the friction between the pusher components and the pressure holes (in actual production, there are 63 pusher components, resulting in a large contact area between them and the pressure plate; actual production has confirmed that the pusher components can drive the pressure plate to rise and fall through friction), the pressure plate also moves downwards synchronously until it contacts the top surface of the tea brick. Afterwards, the pusher plate drives the pusher components to continue moving downwards. The friction applied by the pusher components to the pressure holes causes the pressure plate to press the tea brick firmly against the discharge plate (the pressure holes on the pressure plate correspond one-to-one with the discharge holes on the discharge plate, so the edges around the pressure holes can abut against the edges around the discharge holes). Then, the pusher... The material component presses against the top surface of the tea brick and pushes it downwards along the discharge hole until the bottom of the pusher component fits against the inner wall of the discharge hole, thus cutting the tea brick into small pieces. By setting up pusher components, pressure plates, and discharge plates, the discharge plate cooperates with the pressed tea brick, and then the pressure plate, driven by the pusher component, presses against the position on the tea brick to be cut. Then, the drive cylinder drives the pusher component to push the tea brick for cutting, achieving the cutting of 63 tea bricks at once without manual operation, thus greatly saving production costs. Simultaneously, multiple pusher components drive the pressure plate to move up and down synchronously through friction, allowing the pressure plate to fix the tea brick while ensuring that the pressure applied to the tea brick is not excessive. This avoids the pressure of the drive cylinder directly acting on the pressure plate or discharge plate, which could cause deformation of the edges of the pressure plate and discharge plate (the edges of the discharge plate and pressure plate are 1.8mm thick, and are prone to deformation under excessive force).
[0007] A further configuration of the present invention is as follows: the discharge hole is surrounded by a first partition, the top of the first partition is provided with a V-shaped shearing groove, the bottom of the pressure plate is flat, the pressure hole is surrounded by a second partition, and the second partition can abut against both ends of the first partition.
[0008] With the above technical solution, when it is necessary to shear the tea brick, the pressed tea brick is placed on the discharge plate with the convex side of the tea brick facing down and aligned with the discharge hole. The position of the tea brick to be cut is aligned with the first partition. Then, the pusher moves the discharge plate down until the second partition abuts against the position of the tea brick to be cut (at this time, the adjacent first and second partitions are on the same horizontal plane, and the second partition fixes the small tea brick at both ends of the first partition). After that, the pusher continues to descend, and the pressure applied by the drive cylinder acts on the periphery of the small tea brick through the pusher, pushing the tea brick to be sheared along the first partition. Since the first partition has openings... The shearing groove allows the tea brick to be sheared gradually along the V-shaped groove during the pushing process, resulting in a smoother cut. The first and second partitions, along with the shearing groove, ensure that the pushing component shears the tea brick gradually along the first partition, further smoothing the cut. This gradual shearing also allows the first partition to gradually bear the downward pressure from the pushing component, preventing deformation during the shearing process (the first partition is thin, and the pressure exerted by the cylinder driving the pushing component downwards is high, making it prone to deformation under direct force).
[0009] A further configuration of the present invention is as follows: the pusher includes a first pusher cylinder with a square cross-section and a second pusher cylinder with a cross-section equal to that of the first pusher cylinder. The second pusher cylinder and the first pusher cylinder are distributed adjacent to each other, and there is a set distance between the horizontal plane at the bottom of the first pusher cylinder and the horizontal plane at the bottom of the second pusher cylinder.
[0010] The above technical solution includes a first pusher cylinder and a second pusher cylinder that are adjacent to each other and have hollow interiors. The first pusher cylinder and the second pusher cylinder are at different heights. Therefore, when shearing tea bricks, the non-adjacent first pusher cylinder first pushes the non-adjacent small tea bricks along the first partition to shear them, and then the non-adjacent second pusher cylinder pushes the remaining non-adjacent small tea bricks downwards to shear them. By setting the first and second pusher cylinders at different heights, the small tea bricks are sheared asynchronously in two stages, which is more efficient than applying pressure to two adjacent tea bricks simultaneously. Applying downward pressure to only one of two adjacent tea bricks at a time results in a smoother cut and reduces the risk of deformation of the first partition. Simultaneously, designing the first and second pusher cylinders as hollow units ensures that when they act on the tea brick, they contact the edges of the smaller tea brick near the first partition. This reduces the area of force application compared to a blocky shape, concentrating the force from the first and second pusher cylinders on the smaller tea brick and resulting in a smoother cut.
[0011] A further configuration of the present invention is as follows: four first guide rods are symmetrically arranged on the machine body along the vertical direction. The first guide rods are located at the corners of the discharge plate and move through the push plate and the pressure plate. A first limiting block is provided at the top of the first guide rod, and the top of the push plate can abut against the bottom of the first limiting block. A second limiting block is provided in the middle of the first guide rod, and the bottom of the push plate can abut against the top of the second limiting block. The top of the pressure plate can abut against the bottom of the second limiting block.
[0012] Through the above technical solution, four first guide rods are set on the machine body to limit the movement direction of the pusher plate and the pressure plate. Simultaneously, first and second limit blocks are set, so that when the drive cylinder drives the pusher plate to rise, the pusher pushes the pressure plate to rise until it abuts against the bottom end of the second limit block. Then, the pusher plate continues to rise until it abuts against the bottom end of the first limit block. At this point, the bottoms of the first and second pusher cylinders are located within the pressure hole, and there is a certain distance between the bottom end of the first pusher cylinder and the bottom end of the pressure plate. This ensures that during the next pressing operation, the pressure plate first fixes the tea brick, and then the first... A pusher cylinder pushes the tea brick for shearing; when the drive cylinder drives the pusher plate to descend, the pusher plate descends to the top of the second limit block. At this time, the bottoms of the first and second pusher cylinders both pass through the discharge hole, thus ensuring that the tea brick will not get stuck in the discharge hole after shearing is completed; by setting the first guide rod, the first limit block and the second limit block, the movement direction of the pusher plate and the pressure plate is guided, and the movement distance of the pusher plate and the pressure plate is limited, ensuring that the tea brick will not get stuck in the discharge hole, and that the first and second pusher cylinders can normally shear the tea brick next time.
[0013] A further feature of the present invention is that a plurality of second guide rods are symmetrically arranged on the top of the machine body along the vertical direction, the second guide rods movably passing through the pusher plate and the pressure plate, and the bottom end of the second guide rod is at a set distance from the discharge plate.
[0014] Through the above technical solution, multiple second guide rods are set around the machine body to increase the connection between the pusher plate and the machine body, thereby increasing the stability of the pusher plate movement process. At the same time, there is a certain distance between the second guide rods and the discharge plate, which serves as the feeding port for the pressed tea bricks.
[0015] A further feature of the present invention is that a discharge hopper is provided at the bottom of the machine body at an angle downwards, and the discharge hole is located directly above the discharge hopper.
[0016] Through the above technical solution, the small tea bricks sheared by the first and second pusher cylinders are pushed to the bottom of the discharge hole, fall into the discharge hopper, and then slide along the inclined discharge hopper into the receiving frame, thus completing the entire tea brick shearing process.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] 1. By setting up pushers, pressure plates, and discharge plates, the discharge plate cooperates with the pressed tea bricks. Then, the pressure plate, driven by the pushers, abuts against the position on the tea brick to be cut. After that, the drive cylinder drives the pushers to push the tea bricks for cutting, achieving the cutting of 63 tea bricks at a time without manual operation, thus greatly saving production costs. At the same time, multiple pushers drive the pressure plate to move up and down synchronously through friction, so that the pressure plate can fix the tea bricks while ensuring that the pressure plate does not apply too much pressure to the tea bricks. This avoids the pressure of the drive cylinder directly acting on the pressure plate or discharge plate, which would cause deformation of the edges of the pressure plate and discharge plate (the edges of the discharge plate and the pressure plate are 1.8mm thick, and are prone to deformation if subjected to excessive force).
[0019] 2. By setting up a first and second pusher cylinder with different heights, the small tea bricks are sheared asynchronously in two stages. Compared to applying downward pressure to two adjacent tea bricks simultaneously, applying downward pressure to only one of the two adjacent tea bricks at a time results in a smoother cut and reduces the risk of deformation of the first partition. Furthermore, by making the first and second pusher cylinders hollow, when they act on the tea brick, they contact the four edges of the small tea brick near the first partition. This reduces the area of force application compared to a block shape, making the force from the first and second pusher cylinders more concentrated, thus resulting in a smoother cut.

The bottom surface of the pusher plate 3 is uniformly provided with a plurality of pusher parts 4 with square cross-sections in the vertical direction, and there is a set distance between two adjacent pusher parts 4. A discharge plate 5 is disposed horizontally on the body 1, and a plurality of discharge holes 6 corresponding to the pusher parts 4 are opened vertically on the discharge plate 5. The pusher parts 4 can be movably attached to the inner wall of the discharge holes 6. A pressure plate 7 is movably disposed horizontally on the body 1, and the pressure plate 7 is located between the discharge plate 5 and the pusher parts 4. A plurality of pressure holes 8 corresponding to the discharge holes 6 are opened on the pressure plate 7, and the pusher parts 4 can be movably attached to the inner wall of the pressure holes 8. The pusher parts 4 can drive the pressure plate 7 to rise and fall.
[0029] Furthermore, the discharge hole 6 is surrounded by a first partition 9, and the top of the first partition 9 is provided with a V-shaped shearing groove 10. The bottom of the pressure plate 7 is flat, and the pressure hole 8 is surrounded by a second partition 11. The second partition 11 can abut against both ends of the first partition 9.
[0030] Furthermore, the pusher 4 includes a first pusher cylinder 41 with a square cross-section and a second pusher cylinder 42 with a cross-section equal to that of the first pusher cylinder 41. The second pusher cylinder 42 and the first pusher cylinder 41 are distributed adjacent to each other, and there is a set distance between the horizontal plane where the bottom end of the first pusher cylinder 41 is located and the horizontal plane where the bottom end of the second pusher cylinder 42 is located.
[0031] Furthermore, four first guide rods 12 are symmetrically arranged on the machine body 1 along the vertical direction. The first guide rods 12 are located at the corner of the discharge plate 5. The first guide rods 12 move through the pusher plate 3 and the pressure plate 7. A first limiting block 13 is provided at the top of the first guide rod 12. The top of the pusher plate 3 can abut against the bottom of the first limiting block 13. A second limiting block 14 is provided in the middle of the first guide rod 12. The bottom of the pusher plate 3 can abut against the top of the second limiting block 14. The top of the pressure plate 7 can abut against the bottom of the second limiting block 14.
[0032] Furthermore, a number of second guide rods 15 are symmetrically arranged on the top of the machine body 1 along the vertical direction. The second guide rods 15 move through the pusher plate 3 and the pressure plate 7. The bottom end of the second guide rod 15 is at a set distance from the discharge plate 5.
[0033] Furthermore, a discharge hopper 16 is provided at the bottom of the machine body 1 at an angle downwards, and the discharge hole 6 is located directly above the discharge hopper 16.
[0034] Usage: When pressing tea bricks into shape (such as...) Figure 5When shearing (as shown), the tea brick is laid flat on the discharge plate 5, with the convex side of the tea brick facing down in the discharge hole 6 and the flat side facing up. The position of the tea brick to be cut is aligned with the first partition 9. Then, the drive cylinder 2 is turned on, driving the pusher plate 3 and the pusher 4 to move downward. When the pusher 4 moves downward, since the pressure hole 8 on the pressure plate 7 is in contact with the outer wall of the pusher 4, the friction between the pusher 4 and the pressure hole 8 (in actual production, there are 63 pushers 4, so the contact area between the pusher 4 and the pressure plate 7 is large. Through actual production, it has been determined that the pusher 4 can drive the pressure plate 7 to rise and fall through friction) drives the pressure plate 7 to move downward synchronously until the second partition 11 abuts against the position of the tea brick to be cut (at this time, the adjacent first partition 9 and second partition 11 are on the same horizontal plane, and the second partition 11 fixes the small tea brick). (Fixed at both ends of the first partition 9), then the pusher 4 continues to descend. Since the heights of the first pusher 41 and the second pusher 42 are not the same, when shearing the tea brick, the first pusher 41, which is not adjacent, pushes the small pieces of tea brick along the first partition 9 to shear them. Then, the second pusher 42, which is not adjacent, pushes the remaining small pieces of tea brick downwards to shear them. At the same time, since the first partition 9 has a shearing groove 10, the tea brick is gradually sheared along the V-shaped shearing groove 10 during the process of the first pusher 41 pushing it, making the cut of the tea brick smoother. After being sheared by the first pusher 41 and the second pusher 42, the small pieces of tea brick are pushed to the bottom of the discharge hole 6 and fall into the discharge hopper 16. Then, they slide along the inclined discharge hopper 16 into the receiving frame, thus completing the entire shearing process of the tea brick.
[0035] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0036] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
