Description

Technical Field

[0001] This utility model relates to the technical field of tea shaping and processing, and in particular to a secondary pressure holding and shaping mechanism for tea balls and dragon beads. Background Technology

[0002] There are three main methods of shaping the dragon pearl-shaped tea currently on the market.

[0003] The first method involves placing steam-softened tea leaves on a cloth and then manually rubbing and wrapping the cloth to shape them into balls. The second method uses a simple manual tool for shaping, requiring manual handling of the tea leaf mold, manual placement on the tool, quick clamping to lock it in place, and then pressing it into shape in one go. The third method is a multi-station, one-time integrated pressing and pressure-holding molding process.

[0004] The first shaping method is entirely manual, which is not only inefficient but also makes it difficult to guarantee the uniformity of the size and shape of the spheres produced. The second method, while using molds to ensure the uniformity of the sphere size, also suffers from low processing efficiency due to its semi-automated design. The third method, with its complex and bulky multi-station, single-pressing mold structure, is also problematic because all three methods lack versatility and are primarily for specific applications.

[0005] The third type, although it uses automatic mechanical transmission, also completes the pressing, holding and shaping in the same mold in one go. The mechanism is huge, the mold cost is too high, and the time for changing molds and debugging is as long as 5-8 hours. Therefore, it is mainly a special specification and is troublesome to use. Utility Model Content

[0006] The purpose of this invention is to provide a secondary pressing and shaping mechanism for tea balls and dragon pearls, so as to solve the problem of inconvenience in using existing dragon pearl spherical tea pressing equipment.

[0007] This utility model is achieved through the following technical solution:

[0008] A secondary pressure-holding and shaping mechanism for tea balls includes a turntable, a pressure-holding and shaping mechanism, and a guide bar. Multiple pressure-holding and shaping mechanisms are uniformly fixed on the turntable, arranged in a circular pattern around the center of rotation of the turntable. Each pressure-holding and shaping mechanism includes a roller, a push-pull rod, a first hemispherical mold, and a second hemispherical mold. The first hemispherical mold is fixed relative to the turntable, and the second hemispherical mold is fixed relative to the push-pull rod. A roller is rotatably mounted on the end of the push-pull rod furthest from the turntable. When the pressure-holding and shaping mechanism rotates to the guide bar side, the roller contacts the guide bar.

[0009] In one possible design, the pressure-holding and shaping mechanism further includes a mounting base, a first fixing plate, and a sliding plate. The first fixing plate is located at one end of the mounting base near the turntable, the sliding plate is slidably engaged with the mounting base, the first hemispherical mold is fixed relative to the first fixing plate, and the second hemispherical mold is fixed relative to the sliding plate.

[0010] In one possible design, the sliding plate is connected to the mounting base via a sliding guide rail assembly, which includes a slide table and a guide rail. The guide rail is fixed to the mounting base, the slide table slides on the guide rail, and the sliding plate is fixed to the slide table.

[0011] In one possible design, the push-pull integrated rod passes through the first fixed plate and the sliding plate, the push-pull integrated rod is slidably connected to the first fixed plate, and the push-pull integrated rod is fixedly connected to the sliding plate.

[0012] In one possible design, the guide bar includes an inclined guide section and an arc section. The feeding position for placing the semi-finished tea balls between the first hemispherical mold and the second hemispherical mold is located between the center of the turntable and the end of the guide bar, which is the end of the guide bar away from the inclined guide section.

[0013] In one possible design, a second fixing plate is fixed to the end of the mounting base away from the first fixing plate, a sliding plate is disposed between the first fixing plate and the second fixing plate, and a first spring is provided between the sliding plate and the second fixing plate.

[0014] In one possible design, the first hemispherical mold is fixedly connected to the first fixed plate via a connecting sleeve, and the second hemispherical mold is fixedly connected to the sliding plate via another connecting sleeve. The first hemispherical mold and the connecting sleeve are detachably connected, and the second hemispherical mold and the connecting sleeve are also detachably connected.

[0015] In one possible design, the pressure-holding and shaping mechanism further includes a material ejection core mechanism, which includes a demolding push pin, a first ejector pin, and a second ejector pin. A demolding push pin is slidably disposed in each of the two connecting sleeves that fix the first hemispherical mold and the second hemispherical mold. One end of the demolding push pin is provided with a shoulder. After the demolding push pin is placed in the connecting sleeve, the shoulder is located at the end away from the hemispherical mold. Both the first hemispherical mold and the second hemispherical mold are provided with through holes for the demolding push pin to slide. A second spring is provided between the first hemispherical mold and the shoulder of the demolding push pin, and a second spring is also provided between the second hemispherical mold and the shoulder of the demolding push pin.

[0016] In one possible design, the first ejector pin, the second ejector pin, and the demolding push pin are coaxially arranged, the second ejector pin is fixed to the push-pull integrated rod by a connecting plate, and the first ejector pin is fixed to the second fixing plate.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. The hemispherical molds of different diameters in this utility model can be quickly matched and replaced according to the connecting sleeve. The mold is simple and low in cost. Compared with the multi-station method of one-time molding in the industry, this utility model reduces the mold change and debugging time from 5 to 8 hours to 5 minutes, and increases the efficiency by more than 60 times. It greatly improves the versatility and utilization rate of the equipment. It can process a variety of tea specifications without purchasing multiple machines, reducing the use of dedicated machines and greatly reducing the cost of the number of production equipment and the space occupied by the equipment.

[0019] 2. It is much more efficient than manual shaping, and avoids the large structural space and complexity of integrated compression and pressure holding structures. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0027] Examples, such as Figures 1 to 4 As shown, this embodiment includes a turntable 1, a pressure-holding and shaping mechanism 2, and a guide bar 3. Multiple pressure-holding and shaping mechanisms 2 are evenly fixed on the turntable 1, and are arranged in a circular pattern around the rotation center of the turntable 1. Each pressure-holding and shaping mechanism 2 includes a roller 4, a push-pull integrated rod 5, a first hemispherical mold 9, and a second hemispherical mold 10. The first hemispherical mold 9 is fixed relative to the turntable 1, and the second hemispherical mold 10 is fixed relative to the push-pull integrated rod 5. The end of the push-pull integrated rod 5 away from the turntable 1 is rotatably set... There is a roller 4. When the pressure-holding and shaping mechanism 2 rotates to the side of the guide bar 3, the roller 4 contacts the guide bar 3. Under the rotation of the turntable 1, the roller 4 rolls along the guide bar 3. When the roller 4 rolls on the guide bar 3, it drives the push-pull integrated rod 5 to slide away from the turntable 1, so that the distance between the first hemispherical mold 9 and the second hemispherical mold 10 increases, thereby causing the tea ball that has completed the secondary shaping between the first hemispherical mold 9 and the second hemispherical mold 10 to be released from between the first hemispherical mold 9 and the second hemispherical mold 10, and then collected.

[0028] In this embodiment, the pressure-holding and shaping mechanism 2 further includes a mounting base 6, a first fixing plate 7, and a sliding plate 11. The first fixing plate 7 is located at the end of the mounting base 6 near the turntable 1. The sliding plate 11 is slidably engaged with the mounting base 6. The first hemispherical mold 9 is relatively fixed to the first fixing plate 7, and the second hemispherical mold 10 is relatively fixed to the sliding plate 11. Thus, through the cooperation between the mounting base 6, the first fixing plate 7, and the sliding plate 11, the first hemispherical mold 9 and the second hemispherical mold 10 are in a relatively sliding state. When they slide closer to each other, the tea ball is clamped and shaped. When they slide further apart, the shaped tea ball is removed for subsequent processing.

[0029] Advantageously, the sliding plate 11 is connected to the mounting base 6 via a sliding guide rail assembly to enhance the smoothness of relative sliding between the mounting base 6 and the sliding plate 11. The sliding guide rail assembly includes a slide table 13 and a guide rail 12. The guide rail 12 is fixed on the mounting base 6, and the slide table 13 slides on the guide rail 12. The sliding plate 11 is fixed on the slide table 13. The slide table 13 is a ball-bearing slide table 13, which can greatly improve the smoothness of sliding.

[0030] In this embodiment, the push-pull integrated rod 5 passes through the first fixed plate 7 and the sliding plate 11. The push-pull integrated rod 5 is slidably connected to the first fixed plate 7 and fixedly connected to the sliding plate 11, so that the second hemispherical mold 10 can be driven to slide by the push-pull integrated rod 5.

[0031] Furthermore, the guide bar 3 includes an inclined guide section and an arc section. When the roller 4 is not in contact with the guide bar 3, the distance from the roller 4 to the center of the turntable 1 is less than the distance from the outer arc of the arc section to the center of the turntable 1. The roller 4 is guided by the inclined guide section, so that the roller 4 moves to the arc section. During this process, the roller 4 moves away from the turntable 1, thereby driving the push-pull rod 5 to move together, and also increasing the distance between the first hemispherical mold 9 and the second hemispherical mold 10.

[0032] After the roller 4 finishes rolling from the arc segment, it needs to automatically close the first hemispherical mold 9 and the second hemispherical mold 10. A second fixing plate 14 is fixed at the end of the mounting base 6 away from the first fixing plate 7. The sliding plate 11 is located between the first fixing plate 7 and the second fixing plate 14. A first spring 8 is provided between the sliding plate 11 and the second fixing plate 14. The first spring 8 causes the first hemispherical mold 9 and the second hemispherical mold 10 to close without external force.

[0033] It should be noted that the feeding position for placing the semi-finished tea ball between the first hemispherical mold 9 and the second hemispherical mold 10 is located between the center of the turntable 1 and the end of the guide bar 3. This end is the end of the guide bar 3 away from the inclined guide section. At this end position, the roller 4 is disengaged from the guide bar 3. Under the elastic force of the first spring 8, the second hemispherical mold 10 moves closer to the first hemispherical mold 9 to clamp and close, thus clamping and shaping the semi-finished tea ball.

[0034] Advantageously, the first hemispherical mold 9 is fixedly connected to the first fixed plate 7 through a connecting sleeve 18, and the second hemispherical mold 10 is fixedly connected to the sliding plate 11 through another connecting sleeve 18. The first hemispherical mold 9 and the connecting sleeve 18 are detachably connected, and the second hemispherical mold 10 and the connecting sleeve 18 are also detachably connected. Thus, when processing tea balls of different sizes, the first hemispherical mold 9 and the second hemispherical mold 10 of different sizes can be quickly replaced on the connecting sleeve 18, which not only increases the versatility of the entire shaping mechanism, but also greatly reduces the mold cost.

[0035] In this embodiment, the pressure holding and shaping mechanism 2 further includes a material ejection core mechanism, which includes a demolding push pin 19, a first ejector pin 15, and a second ejector pin 16. A demolding push pin 19 is slidably disposed in each of the two connecting sleeves 18 on which the first hemispherical mold 9 and the second hemispherical mold 10 are fixed. One end of the demolding push pin 19 is provided with a shoulder. After the demolding push pin 19 is placed in the connecting sleeve 18, the shoulder is located at the end away from the hemispherical mold. Both the first hemispherical mold 9 and the second hemispherical mold 10 are provided with through holes for the demolding push pin 19 to slide. A second spring is provided between the first hemispherical mold 9 and the shoulder of the demolding push pin 19, and a second spring is also provided between the second hemispherical mold 10 and the shoulder of the demolding push pin 19.

[0036] Furthermore, the first ejector pin 15, the second ejector pin 16, and the demolding pusher pin 19 are coaxially arranged. The second ejector pin 16 is fixed to the push-pull integrated rod 5 through the connecting plate 17, and the first ejector pin 15 is fixed to the second fixing plate 14. When the roller 4 pulls the push-pull integrated rod 5 to move away from the center of the turntable 1, the second ejector pin 16 approaches the demolding pusher pin 19 on the side of the first hemispherical mold 9 under the drive of the push-pull integrated rod 5, thereby pushing the demolding pusher pin 19 on this side to push out any tea balls that may be present in the first hemispherical mold 9. The second hemispherical mold 10 moves together with the push-pull integrated rod 5, causing the demolding pusher pin 19 on this side to actively approach the first ejector pin 15. Thus, under the obstruction of the first ejector pin 15, the demolding pusher pin 19 is pushed out from the arc bottom of the second hemispherical mold 10.

[0037] It should be noted that after the opening and closing between the first hemisphere mold 9 and the second hemisphere mold 10, the tea ball may fall out automatically, but it may also get stuck on one side of the first hemisphere mold 9 and the second hemisphere mold 10. The design of the ejector core mechanism can ensure that the tea ball will not get stuck on either side of the first hemisphere mold 9 and the second hemisphere mold 10.

[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
