Description

Technical Field

[0001] This invention relates to the field of tea-making machines, and in particular to an automatic tea-making machine for Fu brick tea. Background Technology

[0002] Fu brick tea is a type of compressed tea beverage made by shaping tea leaves into a fixed form. The production of Fu brick tea involves processes such as raw material screening, fermentation and steaming, shaping, drying, and final packaging. Due to the unique "fermentation" process of Fu brick tea, in addition to requiring precise temperature and humidity control in the fermentation room, another important condition is that the shaped bricks must be of moderate density to facilitate the growth of microorganisms. After the Fu brick tea is shaped and removed from the mold, it is sent back to the fermentation room where the temperature and humidity are precisely controlled for optimal fermentation, and adequate ventilation is maintained to ensure a smooth and vigorous fermentation process. Hand-made Fu brick tea is generally processed using existing hand-made molds. The mold has a cubic inner cavity, consisting of a back plate and a cover plate, with the top serving as the feeding port. Tea leaves are continuously and evenly poured into the mold cavity manually using tools such as a winnowing basket through the top feeding port, and then repeatedly hammered into shape by hand with a tea hammer stick. The traditional hand-made Fu brick tea production process relies entirely on manual labor, requiring a high level of expertise from the workers. It is also physically demanding, and only skilled and strong laborers can handle the task. The production process requires close cooperation between a tea feeder and a tea hammerer. In particular, the hammering process is prone to uneven force application due to differences in the workers' physical strength, resulting in inconsistent density of the tea bricks. This affects the appearance and quality of the tea bricks, leading to poor product uniformity and low production efficiency.

[0003] In the prior art, patent publication number CN209284192U discloses a brick tea pressing machine, including a support, a turntable, spring strips, a motor, a reducer, a hammer rod, a mold, and a hammer head. The turntable is located at the top of the support and connected to the reducer. The motor is connected to the reducer and is located at the top of the reducer. The top of the hammer rod is connected to the upper part of the support by at least one spring strip, and the hammer head is located at the lower end of the hammer rod. The mold is located at the bottom of the support and is perpendicular to the hammer head and aligned with it. This brick tea pressing machine, in the brick tea making process, uses a motor and reducer to drive the hammer rod to pound and press the tea leaves in the mold. Compared with the traditional manual pressing process, it replaces manual hammering, saving labor.

[0004] The above technical solutions have solved the problems of existing technologies to a certain extent. However, the molds in the above technical solutions require manual pushing from left to right to make the tea raw materials evenly distributed in the mold packaging to achieve uniform molding. The tea feeding process, that is, the method of adding tea raw materials, is the same as the traditional hand molding process, which requires manual feeding. After molding, the tea hammer rod needs to be lifted by hand and fixed at a high position with a hook before demolding can be carried out, which is quite inconvenient. Therefore, the production efficiency is still low and the labor intensity of the workers is high. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art by designing an automatic tea-making machine for Fu brick tea.

[0015] Beneficial effects:

[0016] This invention provides an automatic tea-forming machine for Fu brick tea, which has the following beneficial effects. Through its structural design, the device installs the Fu brick tea packaging inside the tea-forming mold. Then, the primary and secondary electromagnets disconnect, causing the lifting rod to fall into the tea-forming mold. Simultaneously, the lifting and feeding device lowers its height so that the feeding port is above the tea-forming mold. Then, the intermittent drive device, the lifting and feeding device, and the lateral reciprocating motion device on the mounting frame activate. The lifting and feeding device adds tea material into the tea-forming mold. The intermittent drive device drives the lifting rod to intermittently rise and then separate, descending under gravity to tap and compact the tea material added to the tea-forming mold. The lateral reciprocating motion device drives the tea-forming mold to move left and right, allowing the lifting rod to tap various positions within the tea-forming mold, thus achieving tea forming. When tea forming is complete, a displacement sensor, in conjunction with a sensing plate, detects the height of the lifting rod. When the lifting rod reaches its first maximum height under the intermittent drive, the first-stage electromagnet activates to attract and fix the lifting rod. At this time, the lifting rod remains in a high position and will not descend under the limiting action of the sliding sleeve and the limiting seat. Then, the intermittent motion device drives the lifting rod to rise again. At this time, the lifting rod and the sliding sleeve rise together in the fixed sleeve. When the displacement sensor detects that the lifting rod has reached its second maximum height, the second electromagnet activates to attract and fix the sliding sleeve, thereby realizing the lifting of the lifting rod. At the same time, the lifting and feeding device is raised, so that the lifting and feeding device and the lifting rod move above the tea-making mold, which does not hinder the opening of the tea-making mold to take out the Fu brick tea after tea making. Thus, this device has a high degree of automation, realizing the automatic operation of tea feeding, lifting rod, and left and right movement of the mold, significantly improving production efficiency and effectively reducing the labor intensity of workers.

[0027] Please see Figures 1-6 This invention provides a technical solution: an automatic tea-making machine for Fu brick tea, comprising a mounting frame 1, a lifting rod 2, an intermittent drive device, a limiting seat 3, a sliding sleeve 4, a primary electromagnet 5, a fixed sleeve 6, a secondary electromagnet 7, an induction plate 8, a displacement sensor 9, a transverse reciprocating motion device, a tea-making mold, and a lifting and feeding device. The lifting rod 2 is slidably mounted vertically in the middle of the mounting frame 1. The intermittent drive device is mounted on the upper part of the mounting frame 1, intermittently providing upward power to the lifting rod 2. The limiting seat 3 is mounted in the middle of the mounting frame 1, located around the lifting rod 2 but not in contact with it. A sliding sleeve 4 is mounted on the lifting rod 2 above the limiting seat 3, and a primary electromagnet is mounted on the sliding sleeve 4. A fixed sleeve 6 is fixedly installed on the mounting bracket 1 above the sliding sleeve 4. The inner diameter of the fixed sleeve 6 is greater than or equal to the outer diameter of the sliding sleeve 4 and is fitted outside the sliding sleeve 4. A secondary electromagnet 7 is installed on the fixed sleeve 6. An induction plate 8 is installed on the upper end of the lifting rod 2. A displacement sensor 9 is provided below the induction plate 8 above the mounting bracket 1. A transverse reciprocating motion device is provided at the lower part of the mounting bracket 1. A tea-making mold is installed on the transverse reciprocating motion device. The tea-making mold is located below the lifting rod 2. A lifting and feeding device is provided on the mounting bracket 1 behind the tea-making mold. This device also includes a controller for automatic control. The controller is a PLC controller. The specific control program and circuit connection relationship are common knowledge to those skilled in the art and will not be described in detail here.

[0028] In this invention, the intermittent drive device includes a power motor 10, a first pulley 11, a transmission belt 12, a second pulley 13, a drive wheel 14, a partially driven belt 15, and a support wheel 16. The power motor 10 is fixedly mounted on the upper part of the mounting frame 1. The first pulley 11 is mounted on the output end of the power motor 10. The transmission belt 12 is looped on the first pulley 11, and the other end of the transmission belt 12 is engaged with the second pulley 13. The drive wheel 14 is fixedly connected to the second pulley 13. The drive wheel 14 is rotatably mounted on the upper part of the mounting frame 1. The partially driven belt 15 is fixedly attached to the surface of the drive wheel 14. The distance between the outer surface of the partially driven belt 15 and the axis of the drive wheel 14 is greater than or equal to that of the drive wheel 14. The distance between the shaft center of the drive wheel 14 and the lifting rod 2 is [not specified]. A support wheel 16 is rotatably mounted on the mounting bracket 1. The support wheel 16 is located opposite the drive wheel 14 of the lifting rod 2. The wheel surface of the support wheel 16 is in contact with the lifting rod 2. The power motor 10 drives the first pulley 11 to rotate. The rotation of the first pulley 11 drives the transmission belt 12 to move, which in turn drives the second pulley 13 to rotate. The rotation of the second pulley 13 drives the drive wheel 14 to rotate. Under the influence of the rotation of the incomplete drive belt 15 on the drive wheel 14 and the intermittent contact movement of the lifting rod 2, the lifting rod 2 performs an intermittent upward movement, thereby achieving lifting and lowering. The support wheel 16 is used to balance the pressure exerted on the lifting rod 2 by the incomplete drive belt 15.

[0029] In this invention, an upper guide wheel 17 is installed on the upper part of the mounting frame 1, and a lower guide wheel 18 is installed in the middle of the mounting frame 1. The two upper guide wheels 17 are rotatably installed on the upper part of the mounting frame 1 and are located on both sides of the lifting rod 2 and in contact with the lifting rod 2. The two lower guide wheels 18 are rotatably installed in the middle of the mounting frame 1 and are located on both sides of the lifting rod 2 and in contact with the lifting rod 2. The upper guide wheels 17 and the lower guide wheels 18 provide stable guidance for the lifting rod 2 and reduce the running resistance of the lifting rod 2.

[0030] In this invention, the transverse reciprocating motion device includes a transverse motor 19, a transverse screw 20, a sliding seat 21, and a first guide rail 22. The transverse motor 19 is fixedly installed on the lower part of the mounting frame 1. The transverse screw 20 is installed at the output end of the transverse motor 19. The sliding seat 21 is engaged on the transverse screw 20. The first guide rail 22 is installed on the lower part of the mounting frame 1. The sliding seat 21 is slidably installed on the lower part of the mounting frame 1 through the first guide rail 22. The transverse motor 19 drives the transverse screw 20 to rotate, thereby driving the sliding seat 21 to slide on the first guide rail 22. The reciprocating motion of the sliding seat 21 is realized by the forward and reverse rotation of the transverse motor 19.

[0031] In this invention, a second guide rail 23 is installed on the lower part of the mounting frame 1. Two limit blocks 204 are symmetrically slidably installed on the second guide rail 23. A bidirectional screw 24 is rotatably installed on the lower part of the mounting frame 1. The opposite threads on both sides of the bidirectional screw 24 engage with the two limit blocks 204 respectively. A crank handle 25 is installed on the outer end of the bidirectional screw 24. A proximity switch 26 is installed on the limit block 204. By cranking the crank handle 25, the bidirectional screw 24 is rotated. The rotation of the bidirectional screw 24 causes the two limit blocks 204 to move inward or outward at the same time. According to the different models, i.e., the width of the mold installed on the sliding seat 21, the position of the two limit blocks 204 is adjusted, thereby adjusting the position of the proximity switch 26, thus limiting the left and right reciprocating stroke of the sliding seat 21, matching different tea-making mold sizes, and facilitating adjustment.

[0032] In this invention, the tea-making mold includes a fixed wall 27, a rotating wall 28, a locking rod 29, a locking ear 30, and a rotating bucket 31. The fixed wall 27 is mounted on a sliding seat 21 and has an L-shaped plate structure. The rotating wall 28 is rotatably mounted on the fixed wall 27. The rotating wall 28 also has an L-shaped plate structure. The rotating wall 28 and the fixed wall 27 cooperate to form a rectangular structure. The locking rod 29 is rotatably mounted on the rotating wall 28. The locking ear 30 is fixedly mounted on the right end of the fixed wall 27. The locking ear 30 has a diameter corresponding to that of the locking rod 29. The locking rod 29 falls into the groove to lock the rotating wall 28. The upper end of the fixed wall 27 is equipped with a rotating bucket 31 that can rotate up and down. When in use, first open the rotating bucket 31, then contact the locking rod 29 and the locking ear 30 to open the rotating wall 28. Then place the Fu brick tea packaging box into the fixed wall 27, close the rotating wall 28 and lock it with the locking rod 29, then rotate the rotating bucket 31 downwards to cover the fixed wall 27 and the rotating wall 28. The rotating bucket 31 plays a guiding role for the tea raw materials and prevents the tea raw materials from leaking out.

[0033] In this invention, the fixed wall 27 is detachably connected to the sliding seat 21 by bolts, which facilitates the replacement of the tea-making mold.

[0034] In this invention, the lifting and feeding device includes a vertical guide rail 32, a lifting seat 33, a telescopic cylinder 34, a hopper 35, a drive motor 36, a first sprocket 37, a first transmission chain 38, a second sprocket 39, a deflecting shaft 40, a third sprocket 41, a second transmission chain 42, a fourth sprocket 43, a feeding roller 44, a striking frame 45, a passive block 46, a deflecting block 47, and a torsion spring 48. Two vertical guide rails 32 are symmetrically installed at the rear bottom of the mounting frame 1. The lifting seat 33 is slidably mounted on the vertical guide rails 32. The lower end of the lifting seat 33 is connected to the telescopic cylinder 34. The hopper 35 is fixedly mounted on the lifting seat 33. The drive motor 36 is mounted on the hopper 35. A first sprocket 37 is mounted on the output end of the drive motor 36. A first sprocket 37 is engaged with the first sprocket 37. A transmission chain 38 has a second sprocket 39 engaged at one end. A deflector shaft 40 is fixedly connected to the second sprocket 39 and rotatably mounted on the hopper 35. A third sprocket 41 is fixedly mounted on the outside of the second sprocket 39, and a second transmission chain 42 is engaged on the third sprocket 41. A fourth sprocket 43 is engaged at the other end of the second transmission chain 42, and a feed roller 44 is fixedly connected to the fourth sprocket 43. The feed roller 44 is rotatably mounted at the discharge port of the hopper 35, and the discharge port of the hopper 35 has an arc surface corresponding to the shape of the feed roller 44. A striking frame 45 is rotatably mounted on the lower surface of the hopper 35, and a passive block 46 is mounted on the striking frame 45. A deflector block 47 is mounted on the deflector shaft 40. The deflector block 47 and the passive block... Position 46 corresponds to the height of the actuating block 47 plus the height of the passive block 46, which is greater than the distance between the actuating shaft 40 and the rotating shaft of the striking frame 45. A torsion spring 48 is installed on the striking frame 45, with one end of the torsion spring 48 connected to the hopper 35 and the other end connected to the striking frame 45. The feeding roller 44 is a roller structure with multiple equally sized grooves on its surface. The telescopic cylinder 34 drives the lifting seat 33 to move up and down on the vertical guide rail 32, thereby realizing the lifting of the hopper 35. When feeding is required, the drive motor 36 drives the first sprocket 37 to rotate. The rotation of the first sprocket 37 drives the first transmission chain 38 to move. The movement of the first transmission chain 38 drives the second sprocket 39 to rotate. The rotation of the second sprocket 39 drives the actuating shaft 40 to rotate, and simultaneously drives... The rotation of sprocket 41 drives the movement of transmission chain 42, which in turn drives the rotation of sprocket 43. The rotation of sprocket 43 drives the feeding roller 44 to feed the tea raw materials into the hopper 35. Since the feeding roller 44 has multiple equally sized grooves, the tea raw materials falling into the grooves have the same volume, thus achieving uniform feeding. At the same time, the rotation of the actuating shaft 40 drives the actuating block 47 to rotate. The actuating block 47 rotates and pushes the passive block 46 outward. The passive block 46 then drives the striking frame 45 to rotate outward against the elastic force of the torsion spring 48. Then the actuating block 47 and the passive block 46 separate. Under the elastic force of the torsion spring 48, the striking frame 45 strikes the hopper 35, promoting the feeding of tea raw materials into the hopper 35.

[0035] In this invention, a mounting cover 49 is installed on the upper part of the mounting frame 1. The mounting cover 49 covers the outside of the mounting frame 1. The displacement sensor 9 is installed on the upper part of the mounting cover 49. The mounting cover 49 provides shielding and protection for the inside of the device, and at the same time facilitates the installation of the control panel, control buttons and controller on the mounting cover 49.

[0036] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers, such as PLC controllers, should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0037] In this implementation plan:

[0038] By installing the Fu brick tea packaging inside the tea-building mold, and then disconnecting the primary electromagnet 5 and the secondary electromagnet 7, the lifting rod 2 falls into the tea-building mold. Simultaneously, the lifting and feeding device lowers its height so that the feeding port is above the tea-building mold. Then, the intermittent drive device, the lifting and feeding device, and the lateral reciprocating motion device on the mounting frame 1 activate. The lifting and feeding device adds tea material into the tea-building mold. The intermittent drive device drives the lifting rod 2 to intermittently rise and then separate, descending under gravity to tap and compact the added tea material in the tea-building mold. The lateral reciprocating motion device drives the tea-building mold to move left and right, allowing the lifting rod 2 to tap various positions within the tea-building mold, thus achieving tea building. When tea building is complete, the displacement sensor 9, in conjunction with the sensing plate 8, detects the height of the lifting rod 2. When the lifting rod 2 reaches its first maximum height under the drive of the intermittent drive device... The first-stage electromagnet 5 actuates to attract and fix the lifting rod 2. At this time, under the limiting action of the sliding sleeve 4 and the limiting seat 3, the lifting rod 2 remains in a high position and will not descend. Then, the intermittent motion device drives the lifting rod 2 to rise again. At this time, the lifting rod 2, carrying the sliding sleeve 4, rises together in the fixed sleeve 6. When the displacement sensor 9 detects that the lifting rod 2 has reached the highest height of the second rise, the second electromagnet actuates to attract and fix the sliding sleeve 4, thereby realizing the lifting of the lifting rod 2. At the same time, the lifting and feeding device is raised, so that the lifting and feeding device and the lifting rod 2 move to the top of the tea-making mold, without hindering the opening of the tea-making mold to take out the Fu brick tea after tea making. The displacement sensor can be a laser rangefinder sensor. The displacement sensor 9 and the induction plate 8 form a displacement detection structure.
