Description

Technical Field

[0001] This utility model belongs to the technical field of cutting devices, and in particular relates to an automatic peach petal splitting machine. Background Technology

[0002] When peaches are processed into cans, cutting them in half is one of the processing steps. In order to improve production efficiency, people have proposed special equipment, such as an automatic peach splitting machine (application number 202321107296.8) described in Chinese patent literature, which includes a base, a feeding component, a conveying component, a cutting component, and a discharging component.

[0003] In actual production and processing, uneven peach size is an objective reality. Ideally, peaches should be cut in half along the longitudinal groove on one side, which facilitates subsequent automatic pitting. Existing automatic peach splitting machines cannot cut along this specific location, resulting in poor consistency in the cut shape and hindering the subsequent operation of automatic pitting equipment. Summary of the Invention

[0004] This utility model proposes an automatic peach splitting machine. The technical problem to be solved by this utility model is how to propose an automatic peach splitting machine that can cut peaches in half along the longitudinal groove on one side of the peach.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution: An automatic peach splitting machine includes a frame, on which a conveyor chain device with a fruit loading groove is installed to allow peaches placed in the fruit loading groove to move horizontally is installed. The frame is also equipped with a fruit rubbing device with a fruit rubbing wheel to allow the pointed ends of peaches placed in the fruit loading groove to face upwards, a fruit rotating device to allow peaches placed in the fruit loading groove to rotate horizontally, and a splitting device with a saw blade to cut open peaches placed in the fruit loading groove. The fruit rotating device includes an optical camera for taking a top view of peaches placed in the fruit loading groove and a fruit clamping component with a vertically set rotating shaft for clamping peaches. The fruit rubbing device, optical camera, fruit clamping component and splitting device are arranged sequentially along the peach moving direction of the conveyor chain device.

[0006] This utility model is a combination invention that combines technical solutions such as a conveyor chain device, a fruit-rubbing device, a fruit-turning device, and a petal-opening device to form an automatic peach petal-opening machine that can automatically convey peaches and cut them in half along the longitudinal groove on one side of the peach.

[0007] Compared to existing technologies, when processing peaches using this automatic peach splitting machine, the peaches are placed in the fruit-carrying trough at one end of the conveyor chain relative to the machine frame. The conveyor chain moves the peaches towards the other end of the frame. The conveyor chain drives the peaches to move intermittently. When a peach moves above the conveyor chain, the fruit-rubbing wheel of the fruit-rubbing device rotates. If the peach comes into contact with the fruit-rubbing wheel, it rotates until the concave area at the bottom of the peach aligns with the fruit-rubbing wheel. At this point, the peach separates from the fruit-rubbing wheel, with the pointed end of the peach facing upwards. Next, the peach moves to below the optical camera, which captures a top-down projection image of the peach. The upper computer of the fruit-rotating device processes the image. Then, the peach moves to the fruit-clamping component, where the upper computer controls the fruit-clamping component to hold and rotate the peach based on the image information, so that the longitudinal groove on one side of the peach faces or away from the saw blade. Then, the peach moves to the splitting device, where the saw blade cuts the peach in half along the longitudinal groove on one side. Finally, the peach continues to move, and under the influence of gravity, it slides down.

[0008] In the aforementioned automatic peach petal-opening machine, the conveyor chain device includes multiple conveyor chains and two sprockets for tensioning the conveyor chains. The sprockets are rotatably mounted on the frame via shafts. A first motor connected to one of the sprockets is also mounted on the frame. The conveyor chain includes multiple chain links, and each chain link has a 1 / 4 spherical semi-groove on both sides. Two semi-grooves in two adjacent conveyor chains form a fruit-carrying trough.

[0009] In the aforementioned automatic peach petal-opening machine, the fruit-rubbing device includes a base, a lifting seat, and multiple fruit-rubbing shafts rotatably connected to the lifting seat. The base and the lifting seat are connected by an automatic lifting mechanism. Each fruit-rubbing shaft is fixed with multiple fruit-rubbing wheels that correspond one-to-one with the gap between two adjacent conveyor chains. A second motor is installed on the lifting seat, and the multiple fruit-rubbing shafts are connected to the main shaft of the second motor via a transmission connection.

[0010] In the aforementioned automatic peach petal-opening machine, the gap between the rotating shaft of the fruit clamping component and the gap between two adjacent conveyor chains corresponds one-to-one.

[0011] In the aforementioned automatic peach petal-opening machine, the gaps between the saw blade and the two adjacent conveyor chains correspond one-to-one.

[0012] In the aforementioned automatic peach petal-opening machine, the bottom surface of the chain link has a strip-shaped guide groove, and a guide component embedded in the guide groove is installed on the frame. The guide component and the guide groove cooperate to form a guide structure.

[0013] In the aforementioned automatic peach petal-opening machine, multiple first guide shafts are rotatably mounted on the frame. The first guide shafts are located above the fruit-rubbing device. The guide component is a first guide roller fixedly mounted on the first guide shaft. The first guide roller is also used to support the conveyor chain.

[0014] In the aforementioned automatic peach petal-opening machine, the guide component is a guide rod fixed on the machine frame. The guide rod is horizontally positioned, and the fruit-turning device and the petal-opening device both coincide with the projection of the guide rod. The guide rod is also used to support the conveyor chain.

[0015] In the aforementioned automatic peach petal-opening machine, multiple second guide shafts are rotatably mounted on the frame. The second guide shafts are located below the fruit-turning device and the petal-opening device. Multiple second guide rollers are fixedly mounted on the second guide shafts. Each second guide roller includes a spacer ring located between two adjacent conveyor chains and a support portion located below the conveyor chains. A guide groove adapted to the width of the chain link is formed between the spacer rings of adjacent second guide rollers. The conveyor chains and the second guide rollers cooperate to form a guiding structure. Attached Figure Description

[0032] like Figure 1 and Figure 2 As shown, an automatic peach splitting machine includes a frame 10, a conveyor chain device 20, a fruit-rubbing device 30, a fruit-turning device 40, and a splitting device 50.

[0033] like Figures 10 to 12 As shown, the conveyor chain device 20 includes multiple conveyor chains 21 and two sprockets 22 for tensioning the conveyor chains 21. The sprockets 22 are rotatably mounted on the frame 10 via shafts. A first motor 23, which is connected to one of the sprockets 22, is also mounted on the frame 10. The conveyor chain 21 includes multiple links 24, each link 24 having a quarter-spherical semi-groove 24a on both sides. Two semi-grooves 24a in two adjacent conveyor chains 21 form a fruit-carrying trough 25. When the first motor 23 drives one sprocket 22 to rotate, the sprocket 22 moves continuously in a ring, thereby enabling the conveyor chain device 20 to move peaches placed in the fruit-carrying trough 25 horizontally.

[0034] like Figure 9As shown, the fruit-rubbing device 30 can make the pointed end of the peach placed in the fruit-carrying groove 25 face upward. The fruit-rubbing device 30 can adopt the corresponding mechanism in the peach positioning device of the automatic pitting machine for yellow peaches recorded in Chinese patent literature [authorization announcement number CN201410532549B]; the fruit-rubbing device 30 can also adopt the scheme given in the attached drawings of the specification, that is, the fruit-rubbing device 30 includes a base 31, a lifting seat 32 and multiple fruit-rubbing shafts 33 rotatably connected to the lifting seat 32. The base 31 and the lifting seat 32 are connected by an automatic lifting mechanism 34. Each fruit-rubbing shaft 33 is fixed with multiple fruit-rubbing wheels 35 that correspond one-to-one with the gap between two adjacent conveyor chains 21. A second motor 36 is installed on the lifting seat 32, and the multiple fruit-rubbing shafts 33 are connected to the main shaft of the second motor 36 through transmission.

[0035] The accompanying drawings show that the automatic lifting mechanism 34 includes a bearing shaft rotatably connected to the base 31, multiple cams fixedly mounted on the bearing shaft, and a cylinder mounted on the base 31. The piston rod of the cylinder and the lifting seat 32 are both connected to the bearing shaft through the cams. When the piston rod of the cylinder extends or retracts, the piston rod drives the bearing shaft to rotate through the cams, and then the bearing shaft drives the lifting seat 32 to move up or down through the cams.

[0036] Depending on the actual situation, the automatic lifting mechanism 34 can also be replaced by other structures, such as a motor, a guide rod and guide sleeve assembly connecting the base 31 and the lifting seat 32, and a lead screw and lead nut assembly, with the motor and lead screw and lead nut assembly being connected in a transmission connection.

[0037] The fruit-rotating device 40 enables the peaches placed in the fruit-carrying groove 25 to rotate horizontally. The fruit-rotating device 40 includes an optical camera 41 for capturing a top view of the peaches placed in the fruit-carrying groove 25, and a fruit-clamping assembly 42 with a vertically arranged rotating shaft 42a for holding the peaches. The fruit-rotating device 40 can employ the mechanism described in a Chinese patent document for an orange segmenting machine [Authorization Announcement No. CN109170982B]; or the mechanism described in Chinese patent documents for a pitting device with adjustable pitting size and a fruit pitting machine based on image recognition [Application Publication No. CN120167642A].

[0038] The petal-opening device 50 can cut open the peaches placed in the fruit loading groove 25. The petal-opening device 50 includes a saw blade 51 and a third motor 52. A set of saw blades 51 is provided between the gaps of two adjacent conveyor chains 21. The third motor 52 is connected to the saw blades 51 for transmission.

[0039] like Figure 1 and Figure 2 As shown, the fruit-rolling device 30, optical camera 41, fruit-clamping assembly 42, and petal-opening device 50 are arranged sequentially along the direction in which the peaches are conveyed by the conveyor chain device 20. (See attached diagram in the instruction manual) Figure 3The conveyor chain device 20 conveys peaches from left to right, and the fruit-rubbing device 30, optical camera 41, fruit-clamping component 42 and petal-opening device 50 are also arranged sequentially from left to right.

[0040] like Figures 10 to 12 As shown, the bottom surface of link 24 has a strip-shaped guide groove 24b. (As indicated...) Figure 3 and Figure 8 As shown, multiple first guide shafts 11 are rotatably mounted on the frame 10. The first guide shafts 11 are located above the fruit-rubbing device 30. Multiple first guide rollers 12, corresponding one-to-one with the guide grooves 24b, are fixedly mounted on the first guide shafts 11. The first guide rollers 12 not only support the conveyor chain 21, but the guide grooves 24b and the first guide rollers 12 also cooperate to form a guide structure, which significantly improves the stability of the conveyor chain 21 and the consistency of the peaches' state after being processed by the fruit-rubbing device 30.

[0041] like Figures 5 to 8 As shown, multiple guide rods 13 are fixed on the frame 10. Each guide rod 13 is embedded in the guide groove 24b of multiple chain links 24 in a conveyor chain 21. The guide rods 13 are set horizontally. The fruit turning device 40 and the petal opening device 50 are both projected to the guide rods 13. The guide rods 13 not only support the conveyor chain 21, but the guide grooves 24b and the guide rods 13 also form a guide structure, which significantly improves the movement stability of the conveyor chain 21, improves the accuracy of the captured images, improves the consistency of the peach state after turning, and increases the percentage of peaches that are cut in half along the longitudinal groove on one side of the peach, thereby significantly improving the consistency and pass rate of the peaches after cutting.

[0042] Multiple second guide shafts 14 are rotatably mounted on the frame 10. The second guide shafts 14 are located below the fruit-turning device 40 and the petal-opening device 50. Multiple second guide rollers 15 are fixedly mounted on the second guide shafts 14. Each second guide roller 15 includes a spacer ring 15a located between two adjacent conveyor chains 21 and a support portion 15b located below the conveyor chain 21. A guide groove adapted to the width of the chain link 24 is formed between the spacer rings 15a of adjacent second guide rollers 15. The conveyor chain 21 and the second guide rollers 15 cooperate to form a guide structure, thereby significantly improving the movement stability of the conveyor chain 21.

[0043] The conveyor chain 21 is connected to the frame 10 through the above-mentioned various guiding structures, which significantly improves the movement stability of the conveyor chain 21, thereby improving the stability of the peaches being conveyed, that is, significantly reducing the occurrence of peaches tipping over or rotating during the conveying process.
