Description

Technical Field

[0001] The present invention relates to the technical field of shell-breaking machines, and in particular to an olive pit shell-breaking machine for nuclear carving and its usage method. Background Art

[0002] Nuclear carving is a Chinese folk micro-carving technique and one of the traditional carving arts in Guangdong region. It was included in the national intangible cultural heritage list in 2008. To complete nuclear carving, a large number of olive pits need to be processed. Currently, cutting olive pits still relies on manual labor, mostly completed in the form of casual workers, which leads to low processing efficiency of olive pits. Therefore, an invention of a shell-breaking machine that uses mechanical cutting to process olive pit shell-breaking is needed to reduce the shell-breaking cost, improve production efficiency, and promote the development of olive pit carving technology.

[0003] Chinese invention CN 107183739 B discloses an olive pit shell-breaking and kernel-taking method and device. This device can make the nut shell have elasticity in the long axis direction: apply an external force in the long axis direction to crack and spring open the shell, separate it from the kernel, and thus separate; in order to reduce energy consumption, before shell-breaking, first use a pressing knife to press and split the shell in the direction parallel to the long axis to generate longitudinal cracks in the long axis direction of the shell, reduce the strength of the shell, and then break the shell; after shell-breaking, the shell and the kernel are further separated by screening and winnowing. However, in actual use, when applying an external force in the long axis direction to crack the shell, the problem of uneven distribution of crack patterns easily occurs, which is not suitable for the olive pit carving process.

[0004] Chinese invention CN 114886126 A discloses an olive pit shell-breaking and kernel-taking method and device: the staff pulls out the placement plate of the shell-breaking and kernel-taking device from the inside of the main body of the shell-breaking and kernel-taking device, then evenly places the olive pits on the inner side of the placement groove. After evenly placing the olive pits on the inner side of the placement groove, push the placement plate back into the inside of the main body of the shell-breaking and kernel-taking device, and then start the second cylinder. The second cylinder drives the crushing roller to move during operation, and the olive pits on the inner side of the placement groove are crushed by the crushing roller. However, when this device works, the outer shell of the olive pit will be completely broken and cannot be used for olive pit carving. Summary of the Invention

[0005] The purpose of the present invention is to provide an olive pit shell-breaking machine for nuclear carving, which can solve the above technical problems.

The conveying mechanism includes a storage bin, the bottom of the storage bin is provided with an opening, a vibrating screen is arranged below the opening, the inner bottom of the vibrating screen has an inclination, multiple output ports are arranged at the lowest point of the bottom of the vibrating screen, the output ports are connected with conveying hoses, the ends of the conveying hoses are connected with conveying hard pipes, and olive pits enter the clamping mechanism that plays a fixing role on the olive pits through the ends of the conveying hard pipes. The cracking mechanism includes a tool that can move up and down, and the clamping mechanism can move horizontally and is arranged on one side of the cracking mechanism.

[0007] Preferably, the shape of the output port is limited to allow the olive pit to enter along its tip direction.

[0008] Preferably, the conveying hard pipe is provided with vertical grooves that can be dredged manually when the olive pits are blocked.

[0009] Preferably, two horizontal grooves are arranged near the lower end of the conveying hard pipe, an upper baffle and a lower baffle are respectively arranged in the horizontal grooves, and the upper baffle and the lower baffle are driven by a telescopic motor to move up and down.

[0010] Preferably, the clamping mechanism includes two relatively arranged fixture shells, the fixture shells are driven by finger cylinders to move closer to or away from each other, equidistantly arranged inflatable silica gels are arranged horizontally on the inner sides of the two fixture shells, a lifting cylinder is arranged below the fixture shells, a clamping carrier table is arranged at the top of the lifting cylinder, and equidistantly arranged rubber blocks are arranged horizontally on the upper side of the clamping carrier table, and each rubber block is located in the gap between the inflatable silica gels.

[0011] Preferably, a sliding table is arranged above the fixture shell, a ball screw driven by a stepping motor is arranged on the sliding table, a nut seat is sleeved on the ball screw, and the nut seat is fixedly connected with the finger cylinder.

[0012] Preferably, the cracking mechanism includes a cutting carrier table, support columns are arranged at the bottom of the cutting carrier table, and a tool that can move up and down driven by a lifting mechanism is arranged above the cutting carrier table.

[0013] Preferably, the lifting mechanism includes a motor, a crank is arranged on the output shaft of the motor, the crank is rotatably connected with a connecting rod, a slide rail is arranged below the motor, a slider is slidably sleeved on the slide rail, the slider is fixedly connected with the tool, and the end of the connecting rod is hinged to the top of the tool.

[0014] Preferably, crescent-shaped cutting edges are equally spaced on the cutting edge of the tool.

[0015] A method for using an olive pit shelling machine for nuclear carving, applying the above-mentioned olive pit shelling machine, includes the following steps:

[0016] Step 1: Manually pour olive pits into the storage bin. After the storage bin is dried, the olive pits are discharged to the vibrating screen below at a certain rate.

[0017] Step 2: The vibrating screen vibrates. Due to the vibration and the shape of the output port of the vibrating screen that limits the olive pits to enter along the tip direction, the olive pits enter the conveying hose.

[0018] Step 3: Subsequently, the olive pits fall into the hard conveying pipe 5 under the action of gravity and the vibration of the pipe wall caused by the vibrating screen. The structure of the hard conveying pipe is a triangular shape imitating the olive pit, which can enable the olive pits to fall smoothly.

[0019] Step 4: The lower baffle and the upper baffle of the hard conveying pipe are in the closed state initially, and the distance between the two baffles is the vertical length of an olive pit. When the olive pit enters the hard conveying pipe, the upper baffle opens and the clamping mechanism is in the initial position. When there is no olive pit at the corresponding pipe orifice position, the lower baffle opens, and the olive pit falls into the corresponding position of the fixture. When the lower baffle 8 opens, the upper baffle 9 is in the closed state. After closing the upper baffle, the lower baffle 8 is opened. When both baffles are in the closed state, there is exactly one olive pit between the two baffles.

[0020] Step 5: The olive pits slide through the hard conveying pipe into the cuboid space surrounded by the fixture shell and the rubber block. The finger cylinder drives the fixture shell together with the inflatable silica gel body to contract inward. The rubber block is longitudinally compressed and laterally expanded under the pressure of the fixture shell, and the cuboid space shrinks, restricting the movement of the olive pits. At this time, the line connecting the tips of the olive pits is perpendicular to the fixture shell. The inflatable silica gel body contracts inward together with the fixture shell. When it touches the tip of the olive pit, the fixture shell continues to contract, and the tip of the olive pit begins to sink into the inflatable silica gel body. The greater the degree of contraction of the fixture shell, the deeper the tip of the olive pit sinks into the inflatable silica gel body, and the greater the clamping force.

[0021] Step 6: The lifting cylinder drives the clamping carrier platform together with the rubber block to move downward until the clamping carrier platform disengages from the fixture shell.

[0022] Step 7: The stepping motor rotates, driving the ball screw to rotate. The ball screw drives the nut seat to move forward, the nut seat drives the finger cylinder to move forward, and the finger cylinder drives the fixture shell together with the inflatable silica gel body to move forward until the fixture shell moves to the cutting carrier platform and stops moving.

[0023] Step 8: The motor rotates, driving the tool to move up and down through the crank and connecting rod. Through the downward impact of the tool, the olive pit is split, and the motor stops rotating.

[0024] Step 9: The finger cylinder expands outwards, driving the fixture housing and the inflatable silica gel body to expand outwards together. The stepping motor rotates, driving the fixture housing to retract to the position above the clamping stage. The lifting cylinder rises, driving the clamping stage and the rubber block back to their original positions, waiting for the arrival of the next batch of olive pits, and then returning to Step 1, repeating this process.

[0025] Beneficial effects:

[0026] Through the vibration of the vibrating screen in the present invention, the olive pits enter the conveying hose through the output port and then enter the clamping mechanism through the conveying rigid pipe. There are multiple output ports, conveying hoses, and conveying rigid pipes, which can output multiple olive pits simultaneously. The multiple olive pits are fixed by the clamping mechanism and then transported to the position below the cutter of the shell-breaking mechanism. As the cutter drops, the cutting of the olive pits is completed. The present invention can automatically break the shells of olive pits, saving manpower and material resources. At the same time, the cracking patterns of the olive pits are consistent, improving the quality of shell breaking, which is convenient for olive pit carving. Description of the drawings

[0038] Embodiment 1

[0039] An olive pit shell-breaking machine for nuclear carving, asFigure 1-6 As shown, it is composed of a conveying mechanism Ⅰ, a clamping mechanism Ⅱ, and a shell-breaking mechanism Ⅲ.

[0040] In the conveying mechanism Ⅰ, a drying-type storage bin 2 is installed on the upper elevated rack 1. A vibrating screen 3 is arranged below the storage bin. The vibrating screen is connected to multiple conveying hoses 4, and the conveying hoses 4 are connected to a conveying hard pipe 5. The conveying hard pipe 5 is connected to the clamping mechanism.

[0041] A vibrating motor is attached below the vibrating screen 3. The inner bottom of the vibrating screen 3 has a certain slope and is provided with slag filtering holes. Multiple output ports are provided at the lowest point of the bottom of the vibrating screen. The shape of the output ports is limited to allowing the olive pits to enter along their tip directions, for screening the olive pits so that the olive pits can enter the conveying hoses 4 in a certain posture.

[0042] The conveying hard pipe 5 is provided with a vertical groove, and when the olive pits are blocked, it can be dredged manually. Two horizontal grooves are provided near the lower end. Each horizontal groove is provided with a baffle (the lower baffle 8 and the upper baffle 9). The baffle is connected to a telescopic motor 7. The two baffles are used to orderly convey the olive pits into the clamping mechanism, preventing the olive pits from being blocked in the pipeline or falling out when the clamp is not ready to clamp.

[0043] The clamping mechanism includes two relatively arranged fixture shells 11. The fixture shells 11 are driven by a finger cylinder 13 to move closer to or away from each other. Equally spaced inflatable silica gels 12 are arranged horizontally on the inner sides of the two fixture shells 11. A lifting cylinder 20 is provided below the fixture shells 11. A clamping carrier table 15 is provided at the top of the lifting cylinder 20. Equally spaced rubber blocks 14 are arranged horizontally on the upper side of the clamping carrier table 15. Each rubber block 14 is located in the gap between the inflatable silica gels 12. A sliding table 18 is provided above the fixture shells 11. A ball screw 17 driven by a stepping motor 19 is provided on the sliding table 18. A nut seat 16 is sleeved on the ball screw 17, and the nut seat 16 is fixedly connected to the finger cylinder 13.

[0044] In the clamping mechanism II, the inflatable silica gel body 12 is embedded in the fixture housing 11, and the two form a bionic fixture. The exposed inflatable silica gel body 12 acts as a finger-like part for clamping the two tips of the olive pit. The rectangular space enclosed by the rubber block 14 and the fixture housing 11 is used to store an olive pit that slides down from the conveying hard tube 5. The volume change caused by the compression force of the fixture housing 11 on the rubber block 14 is used to change the rectangular space, thereby restricting the movement space of the olive pit. The finger cylinder 13 is used to control the contraction and expansion of the fixture housing 11. The stepping motor 19 drives the ball screw 17 to rotate, the ball screw 17 drives the nut seat 16 to move back and forth, the nut seat 16 drives the finger cylinder 13 to move back and forth, and at the same time drives the fixture housing 11 and the inflatable silica gel body 12 to move back and forth. The lifting cylinder 20 drives the clamping carrier 15 and the rubber block 14 to move up and down together. Moving downward away from the fixture housing 11 to meet the forward movement of the fixture housing 11, and moving upward to enclose a rectangular space with the fixture housing 11 for receiving the olive pit that slides down from the conveying hard tube 5.

[0045] The shell-breaking mechanism includes a cutting carrier 22. A support column 21 is provided at the bottom of the cutting carrier 22, and a cutter 26 that can move up and down driven by a lifting mechanism is provided above the cutting carrier 22. The lifting mechanism includes a motor 29. A crank 28 is provided on the output shaft of the motor 29. The crank 28 is rotationally connected to a connecting rod 27. A slide rail 24 is installed on the side plate 23 below the motor 29. A slider 25 is slidably sleeved on the slide rail 24. The slider 25 is fixedly connected to the cutter 26. The end of the connecting rod 27 is hinged to the top of the cutter 26. Crescent-shaped cutting edges are evenly distributed on the cutting edge of the cutter 26.

[0046] In the shell-breaking mechanism III, the cutting carrier 22 acts as a similar chopping board and is supported by the support column 21 at the same height as the clamping carrier 15. There is a slider 25 on the slide rail 24, and the slider 25 is connected to the cutter 26 to meet the up and down movement of the cutter 26. When the motor 29 rotates, the cutter 26 is driven to move up and down through the crank 28 and the connecting rod 27. When the cutting edge with crescent-shaped cutting edges moves downward, the circumferential force on the olive pit is relatively uniform, resulting in a relatively flat cross-section. The crescent-shaped cutting edge is relatively close to the outer circumferential line of the olive pit. When the cutter moves downward, the entire circumference of the olive pit comes into contact with the cutter simultaneously, and the force is also relatively uniform, which can ensure the integrity of the olive pit. The olive pit is relatively brittle, and it will automatically break along the direction of the shearing force as long as a little shearing force is applied above it. The cutter does not need to completely penetrate the olive pit.

[0047] Embodiment 2

[0048] Most of the components in this embodiment are the same as those in Embodiment 1. The only difference is that the lifting mechanism adopts a telescopic cylinder. The lower end of the piston rod of the telescopic cylinder is fixedly connected to the top of the cutter, and the cutter is driven by the telescopic cylinder to move up and down to complete the cutting of the olive pit.

[0049] Working and using process:

[0050] A method for using an olive pit cracking machine for nuclear carving, applying the above-mentioned olive pit cracking machine, includes the following steps:

[0051] Step 1: Manually pour olive pits into the storage bin. After the storage bin is dried, the olive pits are discharged to the vibrating screen below at a certain rate;

[0052] Step 2: The vibrating screen vibrates. Due to the vibration and the shape of the output port of the vibrating screen limited to allow the olive pits to enter along the direction of their tips, the olive pits enter the conveying hose;

[0053] Step 3: Subsequently, the olive pits fall into the hard conveying pipe 5 under the action of gravity and the vibration of the pipe wall caused by the vibrating screen. The structure of the hard conveying pipe is a triangular shape imitating the olive pit, which can enable the olive pits to fall smoothly;

[0054] Step 4: The lower baffle and the upper baffle of the lower end of the hard conveying pipe are in the closed state initially, and the distance between the two baffles is the vertical length of an olive pit. When the olive pit enters the hard conveying pipe, the upper baffle opens and the clamping mechanism is in the initial position. When there is no olive pit corresponding to this pipe orifice position, the lower baffle opens, and the olive pit falls into the corresponding position of the fixture. When the lower baffle 8 opens, the upper baffle 9 is in the closed state, and after closing the upper baffle, the lower baffle 8 is opened. When both baffles are in the closed state, there is exactly one olive pit between the two baffles;

[0055] Step 5: The olive pits slide through the hard conveying pipe into the cuboid space surrounded by the fixture shell and the rubber block. The finger cylinder drives the fixture shell and the inflatable silica gel body to contract inward together. The rubber block is longitudinally compressed and laterally expanded under the pressure of the fixture shell, and the cuboid space shrinks. The movement of the olive pits is restricted. At this time, the line connecting the tips of the olive pits is perpendicular to the fixture shell. The inflatable silica gel body contracts inward together with the fixture shell. When it touches the tip of the olive pit, the fixture shell continues to contract, and the tip of the olive pit begins to sink into the inflatable silica gel body. The greater the degree of contraction of the fixture shell, the deeper the tip of the olive pit sinks into the inflatable silica gel body, and the greater the clamping force;

[0056] Step 6: The lifting cylinder drives the clamping carrier platform and the rubber block to move downward together until the clamping carrier platform disengages from the fixture shell;

[0057] Step 7: The stepping motor rotates, driving the ball screw to rotate. The ball screw drives the nut seat to move forward. The nut seat drives the finger cylinder to move forward. The finger cylinder drives the fixture shell and the inflatable silica gel body to move forward together until the fixture shell moves to the cutting carrier platform and stops moving;

[0058] Step 8: The motor rotates, driving the tool to move up and down through the crank and the connecting rod. Through the downward punching of the tool, the olive pit is split, and the motor stops rotating;

[0059] Step 9: The finger cylinder expands outwards, driving the fixture housing together with the inflatable silica gel body to expand outwards. The stepping motor rotates, driving the fixture housing to retract to the position above the clamping stage. The lifting cylinder rises, driving the clamping stage and the rubber block back to their original positions, waiting for the arrival of the next round of olive pits, and then returning to Step 1, and so on.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
