Description

Technical Field

[0001] This utility model relates to the technical field of tea leaf compression molding, and in particular to a general-purpose quick-change compression mechanism and mold. Background Technology

[0002] During tea processing and shaping, molds are needed to achieve the desired shape. However, most molds currently on the market use four support columns or plates to fix the upper and lower molds. The pressure controlling the mold's opening and closing is located at the center of the entire mold's power unit, and the mold itself is also installed at the center of the power unit. This structure makes mold changing inconvenient, time-consuming, and the mold structure is relatively complex and large. Most commonly used tea cake machine molds are upper and lower molds, and some have a middle mold. Their common characteristic is the lack of an active demolding mechanism. During the pressing process, the pressed tea cakes or tea beads often stick to the mold, preventing the formed material from being discharged and causing frequent equipment malfunctions and jamming. This leads to frequent production shutdowns for maintenance and repairs. Current molds are highly specialized, often with multiple forming holes on a single mold set. These molds are heavy, difficult to replace, and have low installation versatility. Summary of the Invention

[0003] The purpose of this utility model is to provide a universal quick-change mold pressing mechanism and mold to solve the problem of inconvenient replacement of existing tea forming molds.

[0004] This utility model is achieved through the following technical solution:

The push rod has an insertion hole, and the push rod is fixedly connected to a first pusher core at the insertion hole. The push rod and the first pusher core are located on the same axis. When a lower mold assembly moves to an aligned state with the upper mold assembly, there is a state on the rotating platform where the push rod and the first pusher core below a mounting position are on the same axis as the top rod.

[0010] On the other hand, a universal quick-change mold is provided, including the upper mold assembly, the middle mold assembly and the lower mold assembly. The lower mold assembly is disposed at one end of the middle mold assembly. The middle mold assembly is fixed on the frame by a mounting plate.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] 1. This utility model, through its installation and connection structure design between the single-sided suspension mechanism and the upper mold assembly, and the turntable assembly and the lower mold assembly, provides ample space for mold changing, enabling faster mold changing and debugging. The mold changing time is reduced from the industry average of 3 hours to 3 minutes. The pressing process is simple in principle, with center-demolded release, preventing tea from sticking, and reducing downtime for maintenance.

[0017] 2. By using a turntable assembly, the process is broken down into smaller steps, allowing for simultaneous demolding and pressing, thus improving efficiency and reducing waiting time. It is compatible with various sizes of tea beads, cakes, and even irregularly shaped tea blocks. Modifying the die head data allows for the use of a universal die rod assembly, eliminating the need for numerous auxiliary structures and significantly improving interchangeability. Changing shapes requires only the die head assembly, minimizing the size and weight of the mold to closely approximate the dimensions of the tea block, thus reducing costs to a minimum.

Detailed Implementation

[0029] 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.

[0030] Example 1, as Figures 1 to 3 As shown, a general-purpose quick mold changing and pressing mechanism is provided. In this embodiment, it includes a single-sided suspension mechanism 1, a turntable assembly 2, and an ejection and demolding mechanism. The single-sided suspension mechanism 1 and the turntable assembly 2 cooperate with each other to control the mold to complete the pressing and forming operation.

[0031] The single-sided suspension mechanism 1 includes an electric telescopic rod 101 and a frame 103. The electric telescopic rod 101 is located at the top of the frame 103 and is fixedly connected to the frame 103. The bottom of the turntable assembly 2 is fixed to the base 3, and the turntable assembly 2 is fixed on the base 3. The turntable assembly 2 includes a rotating platform 201 and a rotation control motor 202. The rotation control motor 202 controls the rotating platform 201 to rotate. The movable rod of the electric telescopic rod 101 is used to fix the upper mold assembly 4. The electric telescopic rod 101 controls the upper mold assembly 4 to perform reciprocating linear motion. The rotating platform 201 is provided with at least two mounting positions for fixing the lower mold assembly 6. The fixed connection between the upper mold assembly 4 and the electric telescopic rod 101, and the fixed connection between the lower mold assembly 6 and the rotating platform 201 are both detachable fixed connections, which facilitates the replacement of the upper mold assembly 4 and the lower mold assembly 6.

[0032] The connection between the electric telescopic rod 101 and the upper mold assembly 4 is unobstructed, providing ample operating space and facilitating the installation and replacement of the upper mold assembly 4. Similarly, the mounting position on the rotating platform 201 away from the single-sided suspension mechanism 1 is also unobstructed by any component, making it easy to replace the lower mold assembly 6.

[0033] In this embodiment, the ejection and demolding mechanism is fixed on the base 3 at one end away from the single-sided suspension mechanism 1. The ejection and demolding mechanism includes a drive motor 7, a gear 8, a rack 9, and an ejector rod 10. The body of the drive motor 7 is fixed on the base 3. The gear 8 is fixed on the shaft of the drive motor 7. The gear 8 meshes with the rack 9. The rack 9 is slidably disposed on the base 3. The ejector rod 10 is fixed on the rack 9.

[0034] Furthermore, a U-shaped frame 11 is fixed below each mounting position. The U-shaped frame 11 is fixed on the rotating platform 201. A push rod 12 is slidably mounted on the U-shaped frame 11. A first spring 13 is provided between the end of the push rod 12 away from the U-shaped frame 11 and the U-shaped frame 11. An insertion hole is provided on the push rod 12. The push rod 12 is fixedly connected to the first push core 14 at the insertion hole. The push rod 12 and the first push core 14 are located on the same axis. When one of the lower mold components 6 moves to the alignment state with the upper mold component 4, there is a state on the rotating platform 201 where the push rod 12 and the first push core 14 below a mounting position are on the same axis as the top rod 10.

[0035] In this state, the drive motor 7 can control the gear 8 to rotate, the gear 8 to move the rack 9 to slide, so that the rack 9 drives the push rod 10 to rise, the rising push rod 10 pushes the push rod 12 to move upward, the push rod 12 then pushes the first push core 14 to move upward, so that the material formed in the lower mold assembly 6 is pushed out through the first push core 14. After the drive motor 7 controls the push rod 10 to retract, under the action of the first spring 13, it can push the push rod 12 to descend and return to the state before being squeezed by the push rod 10.

[0036] It should be noted that the rotating platform 201 can only be controlled to rotate after the push rod 10 is fully retracted, in order to prevent the push rod 12 from colliding with the push rod 10 that is not fully retracted during the rotation of the rotating platform 201, which would cause damage to the equipment.

[0037] Example 2, as Figures 3 to 5 A universal quick-change mold is provided for mounting on a pressing mechanism. It includes an upper mold assembly 4, a middle mold assembly 5, and a lower mold assembly 6. The lower mold assembly 6 is located at one end of the middle mold assembly 5. The middle mold assembly 5 is fixed to the frame 103 by a mounting plate 102. The upper mold assembly 4 and the lower mold assembly 6 are slidably engaged. The upper mold assembly 4 includes a mold rod assembly and a mold head assembly. The mold rod includes an outer sleeve 24 and a central shaft 15. The central shaft 15 is slidably disposed inside the outer sleeve 24. The middle mold assembly 5 has a feed port 501 on its side. A certain amount of tea leaves can be added into the middle mold assembly 5 through the feed port 501, thereby completing the shaping under the mutual compression of the upper mold assembly 4 and the lower mold assembly 6.

[0038] The die head assembly includes a die head 16, a second pusher core 17, and a second spring 18. The die head 16 is fixedly connected to one end of the outer sleeve 24. The second pusher core 17 is slidably engaged with the die head 16. The second spring 18 is disposed between the die head 16 and the second pusher core 17. The second pusher core 17 is fixed to the end of the central shaft 15.

[0039] In this embodiment, the sliding of the central shaft 15 between the outer sleeve 24 is achieved by the electromagnetic push rod 12. The body of the electromagnetic push rod 12 is relatively fixed to the outer sleeve 24. The push rod 12 can be popped out in a controllable manner, thereby controlling the sliding of the central shaft 15 relative to the outer sleeve 24, popping out the second push core 17, so that the upper mold assembly 4 will not be stuck with tea balls, ensuring that the tea balls are always in the lower mold assembly 6 after each shaping. As the lower mold assembly 6 moves to the designated position, the tea balls are pushed out from the lower mold assembly 6 through the first push core 14.

[0040] In this embodiment, the second pusher core 17 is detachably connected to the central shaft 15, and the die head 16 is detachably connected to the outer sleeve 24. The lower die assembly 6 includes an outer sleeve and the die head 16 fixed inside the sleeve. The die head 16 has a hemispherical surface and a through hole. The first pusher core 14 is slidably disposed in the through hole at the lower die assembly 6. The second pusher core 17 has an ejector spindle, which slides with the die head 16 at the through hole inside the die head 16.

[0041] Example 3, as Figure 6 and Figure 7 The difference between this embodiment and embodiment two is that the mold head assembly includes a mold head 16 and a sliding seat 22. The mold head 16 and the sliding seat 22 are slidably engaged. A second spring 18 is provided between the mold head 16 and the sliding seat 22. Two semi-circular plates 19 are fixed on the mold head 16. An indentation strip 20 is fixed between the two semi-circular plates 19. Two pusher shafts 21 are fixed on the sliding seat 22. Each pusher shaft 21 passes through the mold head 16 and the semi-circular plate 19 at one of the semi-circular plates 19. This mold can be used to process tea cakes with central imprints.

[0042] The lower mold assembly 6 includes an outer sleeve tube and a mold head 16 disposed inside the outer sleeve tube. Two semi-circular plates 19 are fixedly disposed inside the mold head 16, and an indentation strip 20 is fixed between the two semi-circular plates 19. In this embodiment, both semi-circular plates 19 are provided with through holes. The first pusher core 14 includes two ejector rods fixed to each other. The two ejector rods 10 pass through the through holes on the two semi-circular plates 19 respectively.

[0043] Example 4, as Figure 8 and Figure 9 The difference between this embodiment and embodiment two is that in this embodiment, the mold head 16 does not have a hemispherical structure, and a flat plate 23 is fixed on the mold head 16. The flat plate 23 is flat, and this mold can be used to process tea cakes without marks.

[0044] 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.
