Description

Technical Field

[0001] This invention relates specifically to the field of drilling equipment technology, and more specifically to a drilling device for monk fruit before drying. Background Technology

[0002] The core purpose of drilling holes in monk fruit before drying is to accelerate moisture evaporation, ensure uniform drying, prevent mold and spoilage, and improve drying efficiency and product quality.

[0003] Monk fruit has thick flesh, a hard peel, and a dense waxy layer, making it difficult for moisture to evaporate naturally. Drilling holes creates "internal and external channels," allowing internal moisture to quickly penetrate to the surface during drying and then be carried away by hot air, reducing drying time by 30%-50%.

[0004] Without perforations, the outer peel will dry and harden first, forming a "sealed layer" that prevents internal moisture from escaping, resulting in a partially cooked fruit that is dry on the outside but wet on the inside. The perforations allow heat to be evenly distributed to the flesh, ensuring simultaneous drying from the inside out and preventing localized mold growth or uneven sugar crystallization. During the drying process, the evaporation of moisture from the flesh creates internal pressure. Without perforations, this pressure cannot be released, easily causing the peel to crack. The perforations release this internal pressure, reducing the cracking rate, preserving the monk fruit's intact shape, and enhancing its commercial value.

[0005] Currently, before drying, each monk fruit needs to be manually drilled with an electric drill. This drilling method is inefficient, labor-intensive, and cannot be used for mass production of monk fruit.

[0006] Furthermore, manual drilling makes it difficult to guarantee the size of each hole, resulting in inconsistent drying effects and affecting the overall quality of the monk fruit. In addition, manual operation also poses certain safety hazards; improper operation may cause injury to the operator. Summary of the Invention

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-10In this embodiment of the invention, a perforation device for monk fruit before drying includes a frame body 1, and a mounting bracket 17 is fixed on the upper rear side of the frame body 1; a reducer 2 is installed below the mounting bracket 17, and a main sprocket 3 is fitted on the output shaft of the reducer 2; the main sprocket 3 is connected to two driven sprockets 24 through a toothed chain 15.

[0041] One of the two driven sprockets 24 is coaxially fitted with a turntable 7, and the other driven sprocket 24 is coaxially fitted with a cam disc 6; the turntable 7 is fitted with a connecting rod 8 via a rotating shaft, and the upper end of the connecting rod 8 is movably connected to a sliding seat 9 via the rotating shaft; a drive rod 11 is fixed to the rear side of the sliding seat 9; a drilling mechanism 12 is connected to the top of the drive rod 11;

[0042] The cam disk 6 has a cam groove inside, and a rotating wheel is slidably connected in the cam groove. The rotating wheel is installed on one side of the upper end of the sliding plate 13 through a rotating shaft. The sliding plate 13 is slidably connected to the worktable 25, and the lower end of the sliding plate 13 is movably connected to the guide plate 14 through a rotating shaft.

[0043] The workbench 25 is fixed to the upper end of the frame body 1, and a through hole is provided on the workbench 25 to facilitate the falling of the monk fruit. The through hole is located below the drilling mechanism 12.

[0044] More specifically, the guide plate 14 has a C-shaped cross-section, and the end of the guide plate 14 away from the sliding plate 13 is movably connected to the frame body 1 by a pin; a collection hopper 19 is provided below the end of the guide plate 14 connected to the sliding plate 13, and the collection hopper 19 is located inside the frame body 1.

[0045] By adopting the above technical solution, during use, the monk fruit enters the through hole on the worktable 25. Blocked by the guide plate 14, the monk fruit remains within the through hole. The reducer 2 drives the main sprocket 3 to rotate, and with the cooperation of the gear chain 15, the driven sprocket 24 and the turntable 7 rotate. When the connecting rod 8 on the turntable 7 is pulled from its highest point to its lowest point, it drives the drilling mechanism 12 to move. At this time, the sliding seat 9 slides downwards on the sliding rod 10, and the drive rod 11 drives the slide table 125 to slide downwards on the guide rod 123. Simultaneously, the buffer spring 124 is compressed, and the drilling motor 127 starts, driving the drill bit 128 to rotate, performing a drilling operation on the monk fruit in the through hole. When the connecting rod 8 on the turntable 7 is pushed from its lowest point to its highest point, it drives the drilling mechanism 12 to reset. The slide table 125 slides upwards to reset under the action of the buffer spring 124. The machine is ready for the next drilling operation. At the same time, another driven sprocket 24 drives the cam disk 6 to rotate. The wheel in the cam disk 6 slides in the cam groove, which drives the sliding plate 13 to slide on the worktable 25. The sliding plate 13 drives the guide plate 14 to swing around the connecting pin of the machine frame 1. When the drilling is completed, the guide plate 14 swings at a certain angle, so that the monk fruit in the through hole is unobstructed and falls from the through hole. It rolls into the collection hopper 19 through the guide groove 122 for collection. At this time, the rotary motor 22 in the feeding hopper 23 drives the dispersing disk 26 to rotate. The monk fruit in the U-shaped groove on the dispersing disk 26 rotates with the dispersing disk 26 to the groove opening, and then rolls out from the groove opening. It is replenished into the through hole on the worktable 25 through the guide groove 122, ready for the next drilling operation. This cycle is repeated to realize the automatic, fast and accurate drilling of monk fruit.

[0046] As a further explanation of the above embodiment, the rotation cycles of the cam disk 6 and the turntable 7 are staggered. When the connecting rod 8 on the turntable 7 is pushed from the lowest point to the highest point, the cam disk 6 drives the sliding plate 13 to press down on the guide plate 14; when the connecting rod 8 on the turntable 7 is pulled from the highest point to the lowest point, the cam disk 6 drives the sliding plate 13 to rise, releasing the obstruction of the guide plate 14 on the monk fruit. This staggered arrangement ensures that when the drilling mechanism is drilling holes in the monk fruit, the guide plate 14 can stably fix the monk fruit, preventing it from shaking or shifting, thereby ensuring the accuracy of drilling. After drilling is completed, the guide plate 14 can swing in time to allow the drilled monk fruit to fall smoothly, while new monk fruit can be quickly replenished to prepare for the next drilling. This design greatly improves the efficiency and continuity of drilling, reduces manual intervention and operation time, and further enhances the automation level of the entire device.

[0047] Please see the appendix Figure 9-10In this embodiment, the drilling mechanism 12 includes a U-shaped seat 121 fixed on the workbench 25, and two guide rods 123 are fixed on the U-shaped seat 121. The upper ends of the guide rods 123 are fixed to the top plate 16. The top plate 16 is fixed to the top of the frame body 1.

[0048] A buffer spring 124 is sleeved on each of the two guide rods 123, and a slide table 125 is slidably connected on the guide rods 123; a motor base 126 is fixed on the outside of the slide table 125, and a drilling motor 127 is fixed on the motor base 126, and a drill bit 128 is installed on the output shaft of the drilling motor 127.

[0049] By adopting the above technical solution, the buffer spring 124 can buffer the downward movement of the slide table 125 and provide a supporting force when the slide table 125 moves upward, making the movement of the slide table 125 on the guide rod 123 more stable, reducing vibration and impact caused by rapid movement, thereby improving the drilling accuracy and stability. The drilling motor 127 is firmly mounted on the slide table 125 through the motor base 126. As the slide table 125 moves up and down, it can precisely control the drill bit 128 to perform the drilling operation on the monk fruit. This design is not only compact in structure but also flexible in operation, and can meet the drilling needs of monk fruit of different sizes and shapes.

[0050] Please see the appendix Figure 7 In this embodiment, the rear side of the slide table 125 is fixed to the upper end of the drive rod 11; the sliding seat 9 is slidably connected to the two slide rods 10; and the two ends of the slide rods 10 are fixed to the frame body 1.

[0051] The drive shaft of the rotating disk 7 is mounted on the frame body 1 through a bearing with a seat; trapezoidal plates are fixed to the upper ends of both sides of the U-shaped seat 121, and a positioning cylinder 129 is fixed to one of the trapezoidal plates; a clamping plate is fixed to the end of the cylinder rod of the positioning cylinder 129.

[0052] By adopting the above technical solution, when the monk fruit enters the through hole, it will remain in the through hole temporarily due to the resistance of the guide plate 14. The cylinder rod of the positioning cylinder 129 extends and clamps the monk fruit on the inside of the trapezoidal plate to prevent the monk fruit from rolling during drilling.

[0053] Please see the appendix Figure 5-8 In this embodiment, idler sprockets 4 and tension sprockets 5 are provided on both sides of the toothed chain 15. The drive shaft for mounting the idler sprockets 4 is mounted on the frame body 1 via a bearing with a seat. The tension sprockets 5 are mounted on the tension arm which is arranged in an L-shape. The tension arm is connected to the mounting bracket 17 via a rotating shaft, and a cylinder (not shown) is also mounted on the tension arm.

[0054] By adopting the above technical solution, the idler sprocket 4 and tensioning sprocket 5 effectively tension and support the toothed chain 15, ensuring that the toothed chain 15 maintains a stable tension force during transmission and preventing the toothed chain 15 from loosening or falling off. The tensioning arm is L-shaped and connected to the mounting bracket 17 via a rotating shaft, allowing the tensioning arm to flexibly adjust the position of the tensioning sprocket 5, thereby achieving precise control of the tension force of the toothed chain 15 and ensuring that the transmission wrap angle of each driving sprocket and driven sprocket is greater than 120 degrees, guaranteeing transmission efficiency. Simultaneously, the cylinder installed on the tensioning arm provides additional power support, enabling the tensioning sprocket 5 to respond more quickly and accurately to changes in the tension force of the toothed chain 15, further improving the stability and reliability of the entire transmission system. This design not only extends the service life of the toothed chain 15 but also reduces equipment failures and downtime caused by problems with the toothed chain 15, improving the production efficiency and economic benefits of the entire Luo Han Guo pre-drying perforation device.

[0055] Please see the appendix Figure 1-2 In this embodiment, a side plate 20 is fixed to the outer side of the frame body 1, and a fixing frame 21 is fixed to the outer side of the upper end of the side plate 20. A feeding hopper 23 is fixed to the top of the fixing frame 21. A dispersing plate 26 is provided on the bottom side inside the feeding hopper 23.

[0056] The bottom of the fixed frame 21 is fixed with a rotary motor 22; the output shaft of the rotary motor 22 is fixedly connected to the dispersing disk 26; the dispersing disk 26 has multiple U-shaped grooves arranged in a ring around its perimeter to facilitate the falling of monk fruit.

[0057] The feeding hopper 23 has a slot on one side to facilitate the rolling out of the monk fruit, and a guide groove 122 is provided on the outside of the slot; the end of the guide groove 122 away from the feeding hopper 23 extends to the through hole on the worktable 25.

[0058] More specifically, the U-shaped grooves around the dispersion disc 26 can accommodate one monk fruit; the hopper 23 is inclined at 10-15 degrees from the outside towards the groove side to facilitate the monk fruit rolling out.

[0059] By adopting the above technical solution, the monk fruit is poured into the feeding hopper 23. Each U-shaped groove of the dispersing disc 26 can hold one monk fruit. When the U-shaped groove rotates and aligns with the guide groove 122, the inclined design allows the monk fruit to roll into the through hole, thus achieving automatic and orderly feeding of the monk fruit. This avoids the tedious process of manually placing the monk fruit one by one, greatly improving feeding efficiency. Simultaneously, this design ensures that each monk fruit falls accurately into the through hole on the worktable, providing a good foundation for subsequent drilling operations. Moreover, the inclined design of the feeding hopper and the rotation of the dispersing disc ensure that the monk fruit maintains a certain interval and order during feeding, further improving the automation level and drilling accuracy of the entire drilling device. Furthermore, this design facilitates observation and adjustment of the feeding process. When monk fruit jams or feeding becomes obstructed, timely cleaning and handling can be carried out, ensuring the stable operation of the entire device.

[0060] The working principle of this invention is as follows: When in use, the monk fruit enters the through hole on the workbench 25. Under the obstruction of the guide plate 14, the monk fruit is kept in the through hole. The reducer 2 drives the main sprocket 3 to rotate. With the cooperation of the toothed chain 15, the driven sprocket 24 and the turntable 7 rotate. When the connecting rod 8 on the turntable 7 is pulled from the highest point to the lowest point, it drives the drilling mechanism 12 to move.

[0061] At this time, the sliding seat 9 slides downward on the sliding rod 10, the drive rod 11 drives the slide table 125 to slide downward on the guide rod 123, and at the same time the buffer spring 124 is compressed. The drilling motor 127 starts and drives the drill bit 128 to rotate, and performs drilling operation on the monk fruit in the through hole. When the connecting rod 8 on the turntable 7 is pushed from the lowest point to the highest point, it drives the drilling mechanism 12 to reset. The slide table 125 slides upward to reset under the action of the buffer spring 124, ready to perform the next drilling operation.

[0062] Meanwhile, another driven sprocket 24 drives the cam disk 6 to rotate. The wheel inside the cam disk 6 slides in the cam groove, causing the sliding plate 13 to slide on the worktable 25. The sliding plate 13 drives the guide plate 14 to swing around the connecting pin to the frame 1. After the drilling is completed, the guide plate 14 swings at a certain angle, so that the monk fruit in the through hole is unobstructed and falls from the through hole, rolling into the collection hopper 19 through the guide groove 122 for collection. At this time, the rotary motor 22 in the discharge hopper 23 drives the dispersing disk 26 to rotate. The monk fruit in the U-shaped groove on the dispersing disk 26 rotates with the dispersing disk 26 to the groove opening, and then rolls out from the groove opening, and is replenished into the through hole on the worktable 25 through the guide groove 122, ready for the next drilling operation. This cycle is repeated, realizing the automatic, fast and accurate drilling of monk fruit.
