Description

Technical Field

[0001] This invention belongs to the field of deep processing technology of bergamot fruit, specifically relating to an automatic peeling device for bergamot fruit. Background Technology

[0002] Studies have shown that the pericarp of bergamot contains a large amount of essential oil, and the extraction of essential oil from the pericarp of bergamot has high economic value.

[0003] Before extracting essential oil from bergamot fruit peel, the peel layer needs to be removed from the freshly picked fruit, while the pulp is processed and reused. Currently, the main method for peeling bergamot fruit is manual, specifically using peeling tools to gradually remove the peel, which is then collected for essential oil extraction. However, this method has several drawbacks, including: low peeling efficiency (approximately 1.5 minutes per fruit for those with closed claws, and approximately 5 minutes per fruit for those with open claws); inconvenience, easily causing hand pain for the operator; and difficulty in uniformly controlling the peel thickness, typically only within 1-3 mm. To uniformly control the peel thickness, increase the total peel volume, and ensure complete removal, multiple layers must be peeled sequentially. Summary of the Invention

[0004] At least in response to the technical problems mentioned in the background section, the present invention aims to provide an automatic peeling device for bergamot fruit.

[0005] The present invention adopts the following technical solution.

[0006] An automatic peeling device for bergamot fruit includes a blade, which is a cylindrical blade positioned below a clamping mechanism. When the clamping mechanism clamps a cylindrical block of bergamot fruit, the cylindrical blade is controlled to move upward and cut the cylindrical block to peel the pulp of the bergamot fruit into the cylindrical blade, thereby obtaining the peel layer of the bergamot fruit.

[0007] Furthermore, the clamping mechanism includes a fixedly arranged inner cylinder with several pin holes. Two arc-shaped blocks are arranged around the inner cylinder. The outer walls of the two arc-shaped blocks are respectively connected to a horizontally arranged drive cylinder. Several radially arranged steel needles are arranged on the inner walls of the two arc-shaped blocks. The steel needles can enter and exit the pin holes. When the extension rod of the drive cylinder is in the initial state, the tip of the steel needle is just located in the pin hole. When the extension rod of the drive cylinder is in the extended state, the tip of the steel needle is located in the inner cavity of the inner cylinder.

[0008] As a preferred embodiment, when the extension rod of the drive cylinder is in the extended state, the inner walls of the two arc-shaped blocks are pressed against the outer wall of the inner cylinder.

[0009] Furthermore, a vertical cylinder is connected to the lower end of the cylindrical cutter, a limit block is fixedly installed at the top of the inner cavity of the cylindrical cutter, and a strip hole is provided on the side wall of the cylindrical cutter. The limit block is connected to the inner cylinder through a connecting rod passing through the strip hole. During the upward extension of the telescopic rod of the vertical cylinder, the cylindrical cutter slides relative to the limit block.

[0010] Furthermore, a hopper is provided at the top of the inner cylinder, and the hopper is connected to the vibrating base. The hopper is located below the discharge port of the screening mechanism, which is used to introduce the target-sized cylindrical Buddha's Hand fruit pieces into the hopper. The screening mechanism is existing technology, and its purpose is to introduce the target-sized cylindrical Buddha's Hand fruit pieces into the appropriate hopper.

[0011] In order to facilitate the peeling of the fruit peel, a removable cover plate is installed on the bottom wall of the inner cavity of the hopper, which can also completely cover the inner cavity of the inner cylinder.

[0012] Furthermore, a discharge mechanism is provided below the inner cylinder. The discharge mechanism includes a discharge trough and a top material assembly is provided at the top of the discharge trough. The top material assembly is used to push the incoming material into the discharge trough.

[0013] Furthermore, the hopper is fixedly connected to the inner cylinder, and the support plate of the inner cylinder is connected to the vibration base.

[0014] As a preferred option, multiple cylindrical cutters are arranged side by side, with each cylindrical cutter matching the same hopper.

[0015] As a preferred option, the cover plate is an L-shaped plate, with the horizontal plate of the L-shaped plate passing through the strip slot on the side wall of the hopper, and the vertical plate of the L-shaped plate connecting to the third cylinder, which is installed on the outer wall of the hopper.

[0016] Beneficial effects: This invention not only significantly improves the efficiency of peeling the peel layer of Buddha's Hand fruit—achieving a peeling efficiency of approximately 30 seconds per fruit for those with closed claws, and typically about 2 minutes per fruit for those with open claws—but also eliminates the need for manual operation, fundamentally solving the problem of hand soreness for the operator. It also increases the total amount of peel material and ensures complete peeling. More importantly, it can uniformly control the thickness of the peeled peel layer, keeping it within 4-6 mm in a single peeling operation, which is beneficial for essential oil extraction.

Detailed Implementation

[0018] The technical solutions 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. Example 1

[0019] Combination Figures 1 to 7 As shown, an automatic peeling device for bergamot fruit includes a blade, which is a cylindrical blade 1. The cylindrical blade 1 is located below the clamping mechanism. When the clamping mechanism clamps the cylindrical bergamot fruit block 2, the cylindrical blade 1 is controlled to move upward and cut the cylindrical bergamot fruit block 2 to peel the pulp of the cylindrical bergamot fruit block 2 into the cylindrical blade. The clamping mechanism includes a fixedly arranged inner cylinder 3 with several pinholes 4. Two arc-shaped blocks 5 are arranged around the inner cylinder 3. The outer walls of the two arc-shaped blocks 5 are respectively connected to a horizontally arranged drive cylinder 10. Several radially arranged steel needles 6 are arranged on the inner walls of the two arc-shaped blocks 5. The steel needles 6 can enter and exit the pinholes 4. When the extension rod of the drive cylinder 10 is in the initial state, the tip of the steel needle 6 is just in the pinhole 4. When the extension rod of the drive cylinder 10 is in the extended state, the tip of the steel needle 6 is in the inner cavity of the inner cylinder 3. When the extension rod of the drive cylinder 10 is in the extended state, the inner walls of the two arc-shaped blocks 5 are against the outer wall of the inner cylinder 3. The lower end of the cylindrical cutter 1 is connected to the vertical cylinder 11. A limit block 7 is fixedly installed at the top of the inner cavity of the cylindrical cutter 1. A strip hole 8 is provided on the side wall of the cylindrical cutter 1. The limit block 7 is connected to the inner cylinder 3 through a connecting rod 9 passing through the strip hole 8. During the upward extension of the telescopic rod of the vertical cylinder 11, the cylindrical cutter 1 slides relative to the limit block 7.

[0020] In this embodiment, a hopper 12 is provided at the top of the inner cylinder 3. Five through holes are arranged side-by-side on the bottom wall of the hopper 12, serving as the inner cavity of the inner cylinder 3. The hopper 12 is connected to a vibrating base 13. The hopper 12 is located below the discharge port of the screening mechanism, which is used to introduce target-sized bergamot fruit cylindrical blocks 2 into the hopper 12. A removable cover plate 14 is provided on the bottom wall of the inner cavity of the hopper 12, which can completely cover the inner cavity of the inner cylinder 3. A discharge mechanism is provided below the inner cylinder 3, including a discharge trough 15. A top-feeding assembly 16 is provided on the top of the discharge trough 15, used to push the incoming material into the discharge trough 15. The hopper 12 is fixedly connected to the inner cylinder 3, and the support plate 18 of the inner cylinder 3 is connected to the vibrating base 13. The vibrating base 13 refers to a commercially available vibrating component capable of vibrating at a preset frequency.

[0021] In this embodiment, multiple cylindrical cutters 1 are arranged side by side, each cylindrical cutter 1 is matched with the same hopper 12. The figure schematically shows five cylindrical cutters 1 arranged side by side, each cylindrical cutter 1 is matched with an independent vertical cylinder 11; the figure schematically shows five inner cylinders 3 arranged side by side, each arc-shaped block 5 is equipped with an independent drive cylinder 10. The cover plate 14 is an L-shaped plate, the horizontal plate of the L-shaped plate passes through the strip groove on the side wall of the hopper 12, and the vertical plate of the L-shaped plate is connected to the third cylinder 17, which is installed on the outer wall of the hopper 12.

[0022] The method of using the automatic peeling device for Buddha's Hand fruit in this embodiment is as follows: Step 1, in the initial state, such as Figure 4 As shown, the tip of the steel needle 6 is located in the needle hole 4, the horizontal plate of the cover plate 14 is located outside the inner cavity of the hopper 12, and the top material assembly 16 is located on the side above the limit block 7. Step 2: Use cutting tools / equipment to pre-cut the harvested and washed fresh Buddha's Hand fruit (the time after harvest should not exceed three days) into cylindrical shapes (length controlled at 10~20mm), i.e., cylindrical material blocks 2. If the claws of the Buddha's Hand fruit have opened, each claw needs to be cut into cylindrical shapes as well. Then, these cylindrical shapes are screened through a screening mechanism to screen out cylindrical shapes of basically the same size (diameter difference not greater than 3mm) and introduce them into the matching hopper 12 (the diameter of the cylindrical shape is 3-5mm smaller than the inner diameter of the inner cylinder 3). After the cylindrical Buddha's Hand fruit block 2 falls into the inner cavity of the hopper 12, the vibrating base 13 is activated, which guides the cylindrical block 2 into the inner cavity of the inner cylinder 3. Then, the drive cylinder 10 is activated, pushing the two arc-shaped blocks 5 to face each other and press against the outer wall of the inner cylinder 3. At this time, several steel needles 6 on the inner wall of the arc-shaped blocks 5 pass through the needle holes 4 and insert into the peel layer of the cylindrical block 2. The state at this time is as follows. Figure 5 As shown; Step 3, next, control the third cylinder 17 to move, so that the horizontal plate of the L-shaped plate passes through the strip groove on the side wall of the hopper 12 and enters the bottom wall of the inner cavity of the hopper 12, thereby realizing that the horizontal plate of the L-shaped plate is close to the top surface of the inner cylinder 3, which is equivalent to the horizontal plate of the L-shaped plate covering the cylindrical block 2. Then, the vertical cylinder 11 is controlled to move. As the telescopic rod of the vertical cylinder 11 extends upward, the cylindrical cutter 1 slides upward relative to the limiting block 7. The cylindrical cutter 1 cuts through the cylindrical block 2 of Buddha's Hand fruit until the top of the cylindrical cutter 1 abuts against the horizontal plate of the L-shaped plate. At this point, the state is as follows: Figure 6 As shown, at this time, the pulp 20 of the Buddha's Hand fruit columnar block remains in the inner cavity of the cylindrical cutter 1, while the peel layer 19 of the Buddha's Hand fruit columnar block is on the outside of the cylindrical cutter 1 and is still stuck by the steel needle 6. Step 4: Control the telescopic rod of the vertical cylinder 11 to reset and drive the cylindrical cutter 1 to move down. When the top of the cylindrical cutter 1 is lower than the top surface of the limit block 7, the pulp 20 of the Buddha's Hand fruit columnar block will detach from the cylindrical cutter 1 and remain on the top surface of the limit block 7. Then control the feeding assembly 16 to work and push the pulp 20 on the top surface of the limit block 7 to the discharge trough 15. Then control the feeding assembly 16 to reset. Next, the extension rod of the control drive cylinder 10 is reset. At this time, the steel needle 6 disengages from the peel layer 19 of the Buddha's Hand fruit columnar material block. The peel layer 19 is no longer limited and falls to the top surface of the limiting block 7. Then, the control of the ejector assembly 16 is activated to push the peel layer 19 on the top surface of the limiting block 7 to the discharge chute 15. The state at this time is as follows: Figure 7 As shown, the top material assembly 16 is then reset.

[0023] For bergamot fruits with closed claws, they can generally be cut into 12-15 cylindrical pieces 2. This requires only two to three steps to peel the peel 19 from these cylindrical pieces 2, taking an average of about 30 seconds to complete the peeling of one bergamot fruit. The continuous action of the steel needle 6 holding the cylindrical piece 2, cutting, and pushing takes less than ten seconds. For bergamot fruits with open claws, they can generally be cut into 30-40 cylindrical pieces 2. This requires only about 10 steps to peel the peel 19 from these cylindrical pieces 2, taking an average of about two minutes to complete the peeling of one bergamot fruit. If multiple automatic peeling devices of different sizes work simultaneously, the peeling efficiency of bergamot fruits can be controlled to within one minute per fruit.

[0024] During use, when precise control of the peel thickness of the bergamot fruit is required, only the length of the steel needle 6 inserted into the inner cavity of the inner cylinder 3 and the diameter of the cylindrical cutter 1 need to be adjusted accordingly. Since the length of the cylindrical block 2 is limited in this solution and the peel is peeled off by punching, the peel thickness can be precisely controlled even when the bergamot fruit is irregular, which also increases the total amount of peel and ensures complete peeling.
