Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, specifically to a winter melon cutting machine. Background Technology

[0002] Winter melon cutting equipment is mostly operated manually or semi-manually. Because the ends of winter melons are relatively small, traditional peeling machines struggle to effectively peel these areas, leading to material waste or requiring manual trimming. This method is not only inefficient but also heavily reliant on operator experience for cutting precision, easily resulting in over- or under-peeling and further material waste. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a winter melon cutting machine, which solves the technical problem that the head and tail of the winter melon need to be removed manually before or after peeling in the existing winter melon peeling machine.

[0004] According to one aspect, at least one embodiment of the present invention provides a winter melon cutting machine, comprising:

[0005] First conveyor;

[0006] A second conveyor is located on one side of the first conveyor and is used to receive the winter melons conveyed by the first conveyor. There is a material leakage gap between the first conveyor and the second conveyor.

[0007] A cutting device, which is movably mounted on the first conveyor, is used to cut off the head and tail of the winter melon.

[0008] For example, at least one embodiment of this disclosure provides a winter melon cutting machine, wherein the cutting device includes:

[0009] A support frame, which is movably mounted on the first conveyor;

[0010] A cutter, wherein the cutter is lifted and positioned on the side of the bracket near the second conveyor;

[0011] An ultrasonic ranging sensor is disposed on the side of the bracket away from the second conveyor, and is used to detect the diameter of the winter melon.

[0012] For example, at least one embodiment of this disclosure provides a winter melon cutting machine, wherein both the first conveyor and the second conveyor include:

[0013] A first conveyor belt and a second conveyor belt are inclined and opposite to each other, and the first conveyor belt and the second conveyor belt form a V-shaped conveying trough, which is used to convey the winter melon.

[0014] For example, at least one embodiment of this disclosure provides a winter melon cutting machine, wherein the support is an arched support, and the cutting blade has the same shape as the V-shaped conveying groove.

[0015] For example, a winter melon cutting machine provided in at least one embodiment of this disclosure further includes:

[0016] The pusher is a pair of pushers, which are respectively raised and lowered on both sides of the cutter. The two pushers are used to push the material adhering to the cutter into the V-shaped conveying groove after the cutter cuts the head and tail.

[0017] For example, at least one embodiment of this disclosure provides a winter melon cutting machine, wherein there are two ultrasonic ranging sensors, which are symmetrically arranged along the center line of the first conveyor.

[0018] For example, a winter melon cutting machine provided in at least one embodiment of this disclosure further includes:

[0019] A fixing clamp is movably mounted on the first conveyor. There are two fixing clamps, which are respectively located on both sides of the cutting device, for fixing the winter melon.

[0020] For example, at least one embodiment of this disclosure provides a winter melon cutting machine, wherein the fixing clamp includes:

[0021] A fixed frame is movably mounted on the first conveyor. There are two fixed frames, which are respectively located on both sides of the cutting device.

[0022] A sliding rod is slidably mounted on the fixed frame. The end of the sliding rod has a fixed assembly connected by a ball joint. After the sliding rod slides, the fixed assembly is used to abut or release the abutment from the winter melon.

[0023] For example, at least one embodiment of this disclosure provides a winter melon cutting machine, wherein the fixing component includes:

[0024] A connector, wherein the connector is ball-jointed to the end of the slide rod, and the connector has a plug portion;

[0025] The abutting member is a flexible member with a groove. The plug is slidably disposed in the groove. The side wall of the groove has an air port. The plug is configured to open or close the air port after sliding.

[0026] For example, a winter melon cutting machine provided in at least one embodiment of this disclosure further includes:

[0027] A material collecting component is disposed below the material leakage gap. The material collecting component has an inclined receiving portion extending toward the first conveyor. The material collecting component is used to collect the material falling through the material leakage gap.

[0028] The beneficial effects of the embodiments of this utility model are as follows:

[0029] In this invention, the first and second conveyors use anti-slip conveyor belts, slightly wider than the diameter of the winter melon, to ensure axial stability during transport and prevent slippage or deviation. This allows for precise positioning of the cutting device. The second conveyor transports the cut winter melon body to the peeling machine. A gap between the two conveyors allows the cut head and tail waste to fall directly into the collection box below without manual intervention. The cutting device is used for automatic positioning and cutting of the head and tail of the winter melon.

[0030] The first conveyor and the cutting device are linked and controlled by a PLC. When the cutting device is cutting, the first conveyor automatically slows down to ensure cutting stability. After the head and tail are removed, the diameter of the winter melon body is uniform, and the peeler blade can fit the surface of the winter melon throughout the process, avoiding the blade from cutting empty or hitting the hard stem of the winter melon due to the small diameter of the head and tail, thus extending the service life of the blade.

[0042] like Figures 1-3 As shown, it illustrates a winter melon cutting machine according to one embodiment of the present invention.

[0043] In some examples, such as Figure 1 As shown, the first conveyor 1 and the second conveyor 2 use non-slip conveyor belts, slightly wider than the diameter of the winter melon, to ensure axial stability of the winter melon during conveying and prevent slippage or deviation. This allows the cutting device to achieve precise positioning. The second conveyor 2 is used to transport the cut winter melon body to the peeling machine. The material leakage gap 201 between the two conveyors allows the cut head and tail waste to fall directly into the collection box below without manual intervention. The cutting device 3 is used to achieve automatic positioning and cutting of the head and tail of the winter melon.

[0044] The first conveyor 1 and the cutting device 3 are controlled by a PLC. When the cutting device 3 is cutting, the first conveyor 1 automatically reduces its speed to ensure cutting stability. After the head and tail are removed, the diameter of the winter melon body is uniform, and the peeling machine blade can fit the surface of the winter melon throughout the process, avoiding the blade from cutting empty or hitting the hard stem of the winter melon due to the small diameter of the head and tail, thus extending the service life of the blade.

[0045] In some examples, such as Figure 2 As shown, the support 301 moves on the first conveyor 1 via a linear guide or slider mechanism, allowing the cutter 302 to adjust its cutting position according to the length of the winter melon. The support 301 uses a rigid metal frame, resulting in minimal vibration during the lifting and lowering of the cutter 302, thus preventing uneven cuts caused by vibration. The cutter 302 is lifted and lowered via an electric push rod or cylinder, automatically adjusting its position based on the diameter of the winter melon detected by the ultrasonic ranging sensor 303.

[0046] The ultrasonic ranging sensor 303 has a measurement range of 5-50cm, dynamically monitoring changes in the diameter of the winter melon. When the diameter reaches the lower limit of the peeling machine's effective processing capacity, a cutting command is triggered. For example, as the diameter of the winter melon head gradually decreases from 1cm to 10cm, the system automatically calculates the cutting position to ensure that the diameter of the main body after removal is ≥10cm.

[0047] Through precise measurement and cutting, the amount of material removed from the head and tail is reduced, thus improving the utilization rate of raw materials. This structure can be adapted to different varieties of winter melon (such as black-skinned winter melon and pink-skinned winter melon), and by preset different diameter thresholds, it can achieve multiple uses in one machine.

[0048] In some examples, such as Figure 1 As shown, the inclined angle of the V-shaped conveyor trough 103 fits against the cylindrical outer surface of the winter melon. Utilizing the friction of the conveyor belt and the clamping effect of the V-shaped conveyor trough 103, the winter melon's axis is automatically aligned with the center line of the V-shaped conveyor trough 103. Even if there are differences in the diameter of the winter melon, it can maintain centered conveying through the adaptive adjustment of the V-shaped conveyor trough 103, reducing positioning errors.

[0049] The inclined conveyor belt increases the contact area between the winter melon and the conveyor surface, and the anti-slip texture (such as rubber ridges) makes it less likely for the winter melon to roll during transportation.

[0050] The winter melon is conveyed in a straight line along the center line in the V-shaped conveyor trough 103. The cutter 302 of the cutting device 3 can be aligned with the axis of the head and tail of the winter melon to ensure that the cut surface is perpendicular to the axis of the winter melon and avoid waste of raw materials caused by oblique cutting.

[0051] Once the winter melon is stably centered, the diameter data detected by the ultrasonic ranging sensor 303 is the true value perpendicular to the axis, rather than the artificially high or low value caused by offset in the traditional conveying method, further reducing waste.

[0052] The winter melon is held by the conveyor belts on both sides in the V-shaped conveyor trough 103. When the cutting device 3 is working, the vertical pressure on the winter melon is balanced by the horizontal component of the V-shaped conveyor trough 103, which is lower than the traditional single belt support, and provides a flatter reference surface for subsequent peeling.

[0053] In some examples, such as Figure 2 As shown, the arched bracket 301 spans the V-shaped conveyor trough 103, forming a bridge-like support structure, allowing the cutter 302 to cut vertically from the top of the winter melon to the bottom of the V-shaped trough without contacting the conveyor belt. The arched bracket 301 is connected to the guide rail of the first conveyor 1 via a bottom slider, allowing it to move horizontally along one side, while the cutter 302 can be adjusted in height on the bracket. The cutting edge of the cutter 302 is V-shaped, perfectly conforming to the outer contour of the winter melon within the V-shaped trough. During cutting, the blade simultaneously cuts into both sides from the top of the winter melon, reducing cutting resistance compared to traditional straight cutters. When the cutter 302 descends to its lowest point, the V-shaped cutting edge can cut through the entire circumference of the winter melon without requiring multiple reciprocating cuts.

[0054] When the cutter 302 is pressed down, the V-shaped conveyor trough 103 provides reverse support to the winter melon, and the friction of the conveyor belts on both sides prevents the winter melon from sliding or rolling, ensuring accurate cutting position.

[0055] In some examples, such as Figure 2As shown, two pusher components 4 are located on both sides of the cutter 302, and are raised and lowered by a cylinder or electric push rod. When the cutter 302 completes cutting and rises to its highest point, the pusher components 4 descend synchronously, pushing the winter melon tissue adhering to the blade towards the V-shaped conveying groove 103. The bottom of the pusher component 4 uses a silicone scraper, which ensures both close contact with the cutter 302 and avoids scratching the blade.

[0056] The pusher component 4 is cleaned immediately after each cut by the cutter 302 to prevent residual winter melon juice and fibers from hardening after drying. The automatic cleaning function of the pusher component 4 reduces the frequency of equipment maintenance, and the timely removal of adhering materials reduces corrosion and wear of the cutter 302, extending the service life of the blade.

[0057] In some examples, such as Figure 2 As shown, two ultrasonic ranging sensors 303 are located on both sides of the winter melon, with the center line of the first conveyor 1 as the axis of symmetry, and simultaneously measure the diameter data of the left and right sides of the winter melon. When the winter melon is shifted during conveying and one side is close to the sensor, the sensor on the other side can still obtain valid data, avoiding the detection blind spot caused by unilateral obstruction.

[0058] The system compares the sensor data on both sides in real time. If the difference is within the normal fluctuation range, the average value is taken as the diameter of the winter melon. If the difference is large, it is determined that the winter melon is being conveyed eccentrically, triggering an alarm and automatically adjusting the speeds of the two conveyor belts on the first conveyor 1 until the data on both sides are consistent. This ensures cutting stability and allows the winter melon to smoothly enter the second conveyor 2 after cutting.

[0059] In some examples, such as Figure 2 As shown, the fixing clamp 5 moves laterally along the first conveyor 1 via an electric slide rail, and its spacing can be automatically adjusted according to the diameter of the winter melon detected by the ultrasonic ranging sensor 303. Before cutting, the clamp initiates a pre-clamping action, fixing the winter melon to the center line of the V-shaped conveyor trough 103 through friction. The clamps on both sides form a three-point fixation with the V-shaped conveyor trough 103 (clamps on both sides + bottom conveyor belt). After reaching the cutting position, the pressure increases, thus fixing the winter melon.

[0060] The clamping / releasing cycle of the clamp is synchronized with the lifting and lowering action of the cutter 302 (the clamp tightens when the cutter descends and loosens when the cutter rises). After the clamp fixes the winter melon, the reaction force of the cutter 302 during cutting is transmitted to the frame of the first conveyor 1 through the clamp (instead of relying solely on the friction of the conveyor belt), thereby reducing the lateral force on the blade.

[0061] In some examples, such as Figure 2As shown, two fixing frames 501 move laterally on the first conveyor 1 via linear guide rails, ensuring that winter melons of different sizes can be effectively clamped. The sliding rod 502 can be driven by an electric cylinder on the fixing frame 501. When the fixing component 503 contacts the winter melon, because the fixing component 503 is connected to the sliding rod 502 via a ball joint, it can rotate freely 360°, ensuring that it always maintains tangential contact with the winter melon and avoids slippage due to angular deviation. The surface of the fixing component 503 is covered with a silicone layer, which can disperse the contact force and prevent indentation.

[0062] In some examples, such as Figure 3 As shown, when the abutment 506 contacts the surface of the winter melon, the plug 505 of the connector 504 slides in the groove 507, blocking the flow path between the internal and external air pressure of the groove 507 and ensuring the fixing strength. When the abutment 506 separates from the surface of the winter melon, the plug 505 of the connector 504 slides in the groove 507, causing the air port 508 to open and the internal air pressure to quickly balance, allowing the abutment 506 to quickly separate from the surface of the winter melon.

[0063] In some examples, such as Figure 1 As shown, the inclined receiving section 601 adopts an inclined design, gradually extending from the bottom of the first conveyor 1 towards the material leakage gap 201. Simultaneously, gravity accelerates the sliding of waste material, ensuring that the waste material (such as the stem and tail) falling from the gap between the first conveyor belt 101 and the second conveyor belt 102 can be quickly guided into the collecting component 6. The width of the collecting component 6 is greater than the material leakage gap 201, ensuring that material collection can be achieved.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
