Description

Technical Field

[0001] This invention relates to the field of primary processing technology for agricultural products, specifically to a fresh bamboo shoot pressing and peeling machine. Background Technology

[0002] Currently, bamboo shoots, as a seasonal and high-value-added agricultural product, rely heavily on manual labor for processing. Traditional manual peeling methods are not only labor-intensive, inefficient, and costly, but there are currently no bamboo shoot peeling machines on the market.

[0003] The main technical bottlenecks in the development of fresh bamboo shoot pressing and peeling machinery are the wide variety of fresh bamboo shoots, the large differences in individual morphology, the high dependence of manual peeling on human experience, the many layers of husk at the tip of the bamboo shoot, the strong wrapping effect, the fewer layers of husk at the root, the risk of damaging the bamboo shoot flesh if the peeling depth is too deep, and the lack of mature and reliable solutions for fresh bamboo shoot pressing and peeling machines. Summary of the Invention

[0004] To address the technical problem of the lack of mature and reliable mechanical equipment for pressing and peeling fresh bamboo shoots in existing technologies, this invention provides a fresh bamboo shoot pressing and peeling machine, the technical solution of which is as follows:

[0005] A fresh bamboo shoot pressing and peeling machine includes a pressing cylinder, a pressing cylinder connecting plate, a linear bearing, a bearing fixing seat, a pressing frame, a peeling device, a push rod T-shaped base, an electric push rod, a guide column, a bamboo shoot support plate, a pneumatic clamping device, a support shaft, a clamping cylinder base plate, a guide column connecting base plate, a safety light curtain sensor, an electrical control system, a fuma wheel, and a frame.

[0006] The upper part of the shell-cutting machine includes a working space, a pressing and cutting space, and a support and clamping space; the lower part is the frame. The pressing cylinder is located at the top of the shell-cutting machine, with its lower end connected to a pressing cylinder connecting plate. The pressing cylinder connecting plate is connected to a linear bearing. The linear bearing and its bearing mounting seat are located on the upper part of the pressing frame. The pressing frame is connected to the pressing cylinder, and a shell-cutting device, a push rod T-shaped base, and an electric push rod are installed at the bottom. The shell-cutting device is connected to the bearing mounting seat and the electric push rod. The push rod T-shaped base is connected to the electric push rod. The electric push rod is connected to the shell cutting device; the guide post connects the pressing cylinder connecting plate and the guide post connecting base plate; the support plate, the pneumatic clamping device, and the clamping cylinder base plate are arranged sequentially from top to bottom in the supporting clamping space; the support shaft connects the support plate, the clamping cylinder base plate, and the guide post connecting base plate; the guide post connecting base plate is installed on the frame; the safety light curtain sensor is set at the top of the working space and the bottom of the supporting clamping space; the electrical control system is set inside the frame; the fuma wheel is installed at the bottom of the frame.

[0007] Furthermore, the pressing cylinder includes a cylinder, a cylinder mounting base, and a flange; the cylinder is bolted to the cylinder mounting base and electrically connected to the electrical control system; the cylinder mounting base is bolted to the pressing cylinder connecting plate and fixes the cylinder; one side of the flange is threaded to the cylinder push rod head, and the other side is bolted to the pressing frame.

[0008] Furthermore, the shell cutting device includes a shell cutting arm connecting seat, a shell cutting arm, a shell cutting arm lug, a ratchet plate, a ratchet connecting seat, a slider, a guide rail, a connecting rod, a deep cutting profile cutter bar, a deep cutting blade, a shallow cutting profile cutter bar, a shallow cutting blade, a return spring, a pneumatic spring check valve, a cutter bar bolt, a return spring fixing bolt, and a limit pin.

[0009] Furthermore, in the shell-cutting device, the shell-cutting arm connecting seat and the shell-cutting arm are bolted together and connected to the bearing fixing seat; the shell-cutting arm is equipped with a shell-cutting arm lug, a guide rail, a pneumatic spring check valve, a return spring fixing bolt, a deep-cutting profile cutter bar, a shallow-cutting profile cutter bar, a cutter bar bolt, a return spring fixing bolt, and a limiting pin; the shell-cutting arm lug is connected to the electric push rod; the ratchet plate is bolted to the ratchet connecting seat; the ratchet connecting seat is mounted on the slider; the slider is movably mounted on the guide rail; the connecting rod connects the ratchet connecting seat to the deep-cutting profile cutter bar and the shallow-cutting profile cutter bar respectively; a deep-cutting blade is installed at the head of the deep-cutting profile cutter bar, and a cutter bar bolt is installed at the tail and connected to the shell-cutting arm; a shallow-cutting blade is installed at the head of the shallow-cutting profile cutter bar, and a cutter bar bolt is installed at the tail and connected to the shell-cutting arm; the return spring connects the cutter bar bolt and the return spring fixing bolt; the pneumatic spring check valve is electrically connected to the electrical control system.

[0010] Furthermore, the support plate is provided with a clamping gap groove and a knife-avoiding groove.

[0011] Furthermore, the pneumatic clamping device includes a clamping cylinder, a clamping claw, and a flexible clamping head; the clamping cylinder is bolted to the base plate of the clamping cylinder and electrically connected to the electrical control system; the clamping claw is installed on the clamping cylinder; the flexible clamping head is wrapped around the clamping claw and is made of flexible silicone material.

[0012] Furthermore, when ready to work, the electric push rod extends, positioning the peeling device in the work space in a vertical position. During operation, the pressing cylinder presses down, moving the peeling device to the pressing peeling space. The shallow and deep cutting blades pass through the tip of the bamboo shoot and cut the bamboo shoot shell. The shallow cutting guide bar passes through the root of the bamboo shoot, while the deep cutting guide bar stops at the upper middle part of the bamboo shoot. As the bamboo shoot shell is being cut, the shallow and deep cutting guide bars pull the corresponding return springs and push the slider upwards on the guide rail via the connecting rod. The ratchet plate passes through the pneumatic spring check valve. When the electric push rod retracts and opens the peeling device, the pneumatic spring check valve locks the teeth through which the ratchet plate passes, preventing the blade bar from resetting.

[0013] Furthermore, when the shell-cutting device rises and resets from the lower shell-cutting space to the waiting work space, the electric push rod extends to restore the shell-cutting device to a vertical position. The pneumatic spring check valve retracts the check block through the air supply of the electrical control system. The reset spring pulls the shallow cutting profile cutter bar and the deep cutting profile cutter bar to reset. The limit pin abuts the tail of the cutter bar to prevent overtravel. After reset and the electrical control system delay, the pneumatic spring check valve cuts off the air supply, and the check block extends.

[0014] Furthermore, the electrical control system is configured as follows:

[0015] (a) Receive the blocking signal from the safety light curtain sensor, determine that no human body or object is blocking the light beam, and start the device when there is no obstruction;

[0016] (b) Manually activate the start button on the electrical control system panel to receive a delayed signal and control the pneumatic clamping device to clamp;

[0017] (c) Receive the delayed signal and control the lowering cylinder to press down the shell-cutting device;

[0020] (f) Receive the delayed signal and control the pneumatic spring check valve to pop out the check stop.

[0021] Beneficial effects

[0022] This invention employs a deep-cutting contour cutter bar and a deep-cutting blade to deeply loosen the multi-layered husks at the tip of fresh bamboo shoots, while simultaneously using a shallow-cutting contour cutter bar and a shallow-cutting blade to prevent excessively deep cuts into the bamboo shoot flesh at the root. This achieves automated operation of the bamboo shoot pressing and peeling machine, which can be used in conjunction with an entire production line or as a standalone machine. Furthermore, the cutting points at the heads of both the shallow-cutting and deep-cutting contour cutter bars can dynamically conform to the irregular outer contour of the bamboo shoot, achieving a near-underactuated adaptive contour cutting. This invention also uses a pneumatic clamping device to hold and tighten the root of the bamboo shoot, effectively preventing the bamboo shoot from tipping over when the peeling device presses down.

[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figure 1 As shown, this embodiment discloses a fresh bamboo shoot pressing and peeling machine, including a frame 18 and a pressing cylinder 1, a pressing cylinder connecting plate 2, a linear bearing 3, a bearing fixing seat 4, a pressing frame 5, a peeling device 6, a push rod T-shaped base 7, an electric push rod 8, a guide column 9, a bamboo shoot support plate 10, a pneumatic clamping device 11, a support shaft 12, a clamping cylinder base plate 13, a guide column connecting base plate 14, a safety light curtain sensor 15, an electrical control system 16, and a fan wheel 17.

[0031] The downward pressing cylinder 1 is mounted on the downward pressing cylinder connecting plate 2 at the upper part of the working space 19, and is used for pressing down and pushing and pulling up to reset the shell cutting device 6 on the downward pressing frame 5. The downward pressing cylinder connecting plate 2 is located at the bottom of the downward pressing cylinder 1, and together with the guide post 9 and the guide post connecting base plate 14, forms the working space 19, the downward pressing and shell cutting space 20, and the support clamping space 21 from top to bottom. The downward pressing cylinder connecting plate 2 is square, and has rectangular through holes on four sides near the downward pressing cylinder 1, which facilitates the installation of the bearing fixing seat 4 on the downward pressing frame 5, and prevents the bearing fixing seat 4 and the shell cutting arm connecting seat 601 from hitting the downward pressing cylinder connecting plate 2 when the cylinder 101 retracts and drives the downward pressing frame 5 to rise. The linear bearing 3 and the bearing fixing seat 4 are located in the working space 19. The pressure frame 5 is used for the movement of the lower pressure frame 5 on the guide post 9 and for the opening and closing of the shell cutting device 6. The lower pressure frame 5 is mounted on the linear bearing 3 and connected to the lower pressure cylinder 1 through the flange 103 of the lower pressure cylinder 1. It serves as the mounting frame for the shell cutting device 6, the electric push rod 8, and the push rod T-shaped base 7. The lower pressure frame 5 is composed of a square steel frame and a thick plate welded together. The thick plate of the lower pressure frame 5 has a long rectangular opening slot, which facilitates the rotation of the shell cutting arm connecting seat 601 of the shell cutting device 6 around the bearing fixing seat 4 when the electric push rod 8 extends and retracts, thereby realizing the opening and closing of the shell cutting device 6 and preventing the shell cutting arm connecting seat 601 and the shell cutting arm 602 from hitting the lower pressure frame 5. The shell cutting device 6 is connected to the bearing fixing seat 4 and the electric push rod 8. The push rod T-shaped base 7 is mounted on the lower pressure frame 5. The four sides of the bottom of the pressure frame 5; the base of the electric push rod 8 is connected to the push rod T-shaped base 7, used to control the opening and closing of the shell cutting device 6, and is electrically connected to the electrical control system 16. When the operation is finished and before the material needs to be removed, the electric push rod 8 first retracts the push rod to open the shell cutting device 6 outward, so that the shallow cutting blade 6012 and the deep cutting blade 6010 are removed from the shell. When the shell cutting device 6 rises from the lower shell cutting space 20 to the waiting work space 19 and resets through the delay control of the electrical control system 16, the electric push rod 8 extends to restore the shell cutting device 6 to the vertical position; the head of the guide post 9 is connected to the lower cylinder connecting plate 2 at the upper part of the waiting work space 19, and the tail is connected to the guide post connecting base plate 14 under the support clamping space 21, used to support the lower cylinder connecting plate 2. The connecting plate 2 and the linear bearing 3 move on the guide post 9; the bamboo shoot support plate 10 is used to support the root of the fresh bamboo shoot 22 when manually feeding, and is provided with a clamping gap groove and a knife avoidance groove, so that the clamping claw 1102 can extend out of the support plate 10 to clamp the bamboo shoot shell at a certain distance, and the knife avoidance groove prevents the shallow cutting profile knife bar 6011 and the shallow cutting blade 6012 from hitting the support plate 10, causing damage and interference to the shallow cutting profile knife bar 6011 and the shallow cutting blade 6012; the pneumatic clamping device 11 is set in the middle of the support clamping space 21; the support shaft 12 and the clamping cylinder base plate 13 are set in the lower part of the support clamping space 21, and the support shaft 12 is used to connect the bamboo shoot support plate 10, the clamping cylinder base plate 13 and the guide post connecting base plate 14 to form the support clamping space 21;The guide post connecting base plate 14 is located at the bottom of the support clamping space 21 and installed above the frame 18, used to fix the tail of the guide post 9, the support shaft 12, and the clamping cylinder base plate 13; the safety light curtain sensor 15 is respectively located at the upper part of the working space 19 and the lower part of the support clamping space 21, used to determine that no human body or object is blocking the light beam, ensuring that the whole machine is in a safe state when the pressing frame 5, the shelling device 6, and other devices are pressed down or reset; the electrical control system 16 is used to coordinate the actions of each device; the fuma wheels 17 are installed at the four corners below the frame 18 for the movement and fixation of the fresh bamboo shoot pressing and shelling machine.

[0032] like Figure 2 As shown, the pressing cylinder 1 includes: cylinder 101, cylinder mounting base 102, and flange 103; cylinder 101 is bolted to cylinder mounting base 102 and electrically connected to electrical control system 16; cylinder mounting base 102 is bolted to pressing cylinder connecting plate 2 to fix cylinder 101; one side of flange 103 is threaded to the push rod head of cylinder 101, and the other side is bolted to pressing frame 5; when manual feeding is completed and the start button of electrical control system panel is activated, pneumatic clamping device 11 clamps and holds the root of fresh bamboo shoot 22. After a delay by electrical control system 16 and the safety light curtain sensor 15 determines that no human body or object is blocking the light beam, in a safe operating state, pressing cylinder 1 pushes pressing frame 5 down, and after completing the operation, it resets, and cylinder 101 retracts to drive pressing frame 5 up.

[0033] like Figure 3a , Figure 3b As shown, the shell-cutting device 6 includes: a shell-cutting arm connecting seat 601, a shell-cutting arm 602, a shell-cutting arm lug 603, a ratchet plate 604, a ratchet connecting seat 605, a slider 606, a guide rail 607, a connecting rod 608, a deep-cutting profile cutter bar 609, a deep-cutting blade 6010, a shallow-cutting profile cutter bar 6011, a shallow-cutting blade 6012, a return spring 6013, a pneumatic spring check valve 6014, a cutter bar bolt 6015, a return spring fixing bolt 6016, and a limiting pin 6017.

[0034] The shell-cutting arm connecting seat 601 and the shell-cutting arm 602 are bolted together and connected to the bearing fixing seat 4 on the lower cylinder connecting plate 2 by a pin. The shell-cutting arm 602 and the shell-cutting arm lug 603 are bolted together. The push rod mounting hole of the electric push rod 8 is connected to the pin of the shell-cutting arm lug 603. Two sets of guide rails 607, pneumatic spring check valves 6014, and return spring fixing bolts 6016, spaced 200mm apart from top to bottom, are bolted to the shell-cutting arm 602. The deep-cutting profile cutter bar 609 and the shallow-cutting profile cutter bar 6011 are connected to the pin of the shell-cutting arm 602. The shell-cutting arm 602 is mainly used for the installation and fixing of the components of the shell-cutting device 6 and for the deep-cutting profile cutter bar 609 and the shallow-cutting profile cutter bar 601. 1. Rotation around an axis when moving along the outer contour in contact with the surface of fresh bamboo shoot 22; the ratchet plate 604 is bolted to the ratchet connecting seat 605, the ratchet connecting seat 605 is mounted on the slider 606, and the slider 606 can move up and down on the guide rail 607; the connecting rod 608 connects the corresponding ratchet connecting seat 605 to the deep cutting contour cutter bar 609 and the shallow cutting contour cutter bar 6011 respectively with pin shafts; the deep cutting contour cutter bar 609 and the shallow cutting contour cutter bar 6011 are respectively equipped with deep cutting blades 6010 and shallow cutting blades 6012 at their heads, and are all provided with cutter bar bolts 6015 at their tails. The tail pin holes are connected to the shell cutting arm 602 through pin shafts, and are in a horizontal position when in operation. The deep-cutting blade 6010 is of moderate length and relatively thick. Its main function is to perform a deep double cut on the bamboo shoot from the tip to the middle, which is passed by the shallow-cutting blade 6012, to better loosen the bamboo shoot shell at the tip and facilitate subsequent peeling operations. The shallow-cutting blade 6012 mainly functions to cut the shell from the tip to the root of the bamboo shoot. The shallow-cutting blade 6012 is of moderate length and can effectively cut a small amount of the outer bamboo shoot shell when cutting the root of the bamboo shoot, without making too deep a cut into the inner bamboo shoot flesh. The return spring 6013 is connected to the blade bolt 6015 and the return spring fixing bolt 6016, and is used when the deep-cutting contour blade 609 and the shallow-cutting contour blade 6011 are in contact with the fresh bamboo shoot. When the surface contacts and slides along the outer contour, the pulling force of the return spring 6013 provides the cutting pressure for the deep cutting profile cutter bar 609 and the shallow cutting profile cutter bar 6011. When the pneumatic spring check valve 6014 retracts the check block through the electrical control system 16, the return spring 6013 pulls the shallow cutting profile cutter bar 6011 and the deep cutting profile cutter bar 609 to reset. The pneumatic spring check valve 6014 is electrically connected to the electrical control system 16. The limiting pin 6017 is wrapped with buffer rubber, which holds the tail of the cutter bar against the return spring 6013 when it pulls the deep cutting profile cutter bar 609 and the shallow cutting profile cutter bar 6011 to prevent the cutter bar from overtraveling during operation.

[0035] During operation, the peeling device 6 moves from the waiting space 19 to the pressing peeling space 20. The shallow cutting blade 6012 and deep cutting blade 6010 mounted on the shallow cutting profiler 6011 and deep cutting profiler 609 of the peeling device 6 pass through the tip of the bamboo shoot 22 and cut the bamboo shoot shell. The shallow cutting profiler 6011 passes through the root of the bamboo shoot 22, and the deep cutting profiler 609 stops at the upper middle part of the bamboo shoot 22. While peeling along the surface of the bamboo shoot shell, the shallow cutting profiler 6011 and deep cutting profiler 609 pull the corresponding return spring 6013, which in turn pushes the slider 606 upward on the guide rail 607 via the connecting rod 608. The ratchet plate 604 on the slider passes through the pneumatic spring check valve 6014. When the electric push rod 8 retracts to open the peeling device 6, the pneumatic spring check valve 6014... The ratchet plate 604 is locked by its teeth to prevent the return spring 6013 from directly resetting the shallow cutting profiler 6011 and the deep cutting profiler 609. This prevents the shallow cutting profiler 6011 and the deep cutting profiler 609 from constantly clamping the fresh bamboo shoot 22, which would prevent the shallow cutting blade 6012 and the deep cutting blade 6010 from being pulled out of the bamboo shoot shell smoothly. When the shell-cutting device 6 rises from the lower shell-cutting space 20 to the waiting space to reset, the electric push rod 8 extends to restore the shell-cutting device 6 to a vertical position. The pneumatic spring check valve 6014 retracts the check block through the air supply of the electrical control system 16. The return spring 6013 pulls the shallow cutting profiler 6011 and the deep cutting profiler 609 to reset. After the reset and the delay of the electrical control system 16, the pneumatic spring check valve 6014 cuts off the air supply, and the check block extends.

[0036] like Figure 4 As shown, the pneumatic clamping device 11 includes: a clamping cylinder 1101, a clamping claw 1102, and a flexible clamping head 1103; the clamping cylinder 1101 is bolted to the clamping cylinder base plate 13; the clamping cylinder 1101 is electrically connected to the electrical control system 16; the clamping claw 1102 is installed on the clamping cylinder 1101 and can move between the clamping gaps of the bamboo shoot support plate 10, used to clamp the roots of the fresh bamboo shoot 22 when manually feeding; the flexible clamping head 1103 is wrapped around the clamping claw 1102 and is made of flexible silicone material; during operation, the operator places the tipped and root-removed fresh bamboo shoot 22 in the center of the pneumatic clamping device and on the bamboo shoot support plate 10, and starts the electrical control system panel. After a delay by the electrical control system and the safety light curtain sensor determining that no human body or object is blocking the light beam, the pneumatic clamping device clamps and holds the roots of the fresh bamboo shoot 22 tightly, which can effectively prevent the fresh bamboo shoot 22 from tipping over when the peeling device 6 presses down.

[0037] The electrical control system 16 is electrically connected to the cylinder 101 of the pressing cylinder 1, the pneumatic spring check valve 6014 of the shell cutting device 6, the electric push rod 8, the clamping cylinder 1101 of the pneumatic clamping device 11, and the safety light curtain sensor 15, respectively. The electrical control system 16 is configured to: receive the blocking signal from the safety light curtain sensor 15, determine that no human body or object is blocking the light beam, and only start the device when no human body or object is blocking the light beam; manually activate the start button on the electrical control system panel, receive a delay signal to control the clamping cylinder 1101 of the pneumatic clamping device 11 to clamp; receive the delay signal... The system controls the downward pressing cylinder 101 to press down the shell cutting device 6; when the downward pressing cylinder 101 is fully extended, it receives a delayed signal, and the electric push rod 8 retracts to open the shell cutting device 6; upon receiving a delayed signal, it controls the downward pressing cylinder 101 to lift the shell cutting device 6, and the electric push rod 8 extends to restore the shell cutting device 6 to its vertical position, controlling the pneumatic spring check valve 6014 of the shell cutting device 6 to retract its check stop, so that the shallow cutting profile cutter bar 6011 and the deep cutting profile cutter bar 609 are reset; upon receiving a delayed signal, it controls the pneumatic spring check valve 6014 of the shell cutting device 6 to pop out its check stop.

[0038] In summary, the working process of the fresh bamboo shoot pressing and peeling machine of the present invention is as follows: The fresh bamboo shoot 22, with its tip and root removed, is manually placed in the center of the pneumatic clamping device 11, and the start button on the panel of the electrical control system 16 is activated; the pneumatic clamping device 11, controlled by the electrical control system 16, clamps and holds the root of the fresh bamboo shoot 22; under safe operating conditions, the pressing cylinder 1 pushes the four sets of peeling devices 6 on the pressing frame 5 downwards. During the downward pressing process, the shallow cutting blade 6012 on the shallow cutting contour blade 6011 on the peeling device 6 cuts from the tip of the bamboo shoot to the root, and the deep cutting blade 6010 on the deep cutting contour blade 609 cuts from the tip of the bamboo shoot to the upper middle part of the bamboo shoot. The shallow cutting blade 6012 can completely cut the bamboo shoot shell from top to bottom, but does not make excessively deep cuts to the bamboo shoot flesh at the root. The deep cutting blade 6010 cuts the shallow cutting blade 6012. The cut marks are then double-cut to separate the bamboo shoot tips and the uncut middle sections, loosening the bamboo shoot shell to the desired depth. After a delay, the electric push rod 8 retracts, opening the cutting device 6 and pulling the shallow cutting blade 6012 and deep cutting blade 6010 out of the bamboo shoot shell. Next, the pressing cylinder 1 drives the pressing frame 5 to reset, the clamping cylinder 1101 of the pneumatic clamping device 11 opens, the electric push rod 8 extends, restoring the cutting device 6 to a vertical position. The pneumatic spring check valve 6014 retracts the check block through the electrical control system 16, and the reset spring 6013 pulls the shallow cutting profile blade 6011 and the deep cutting profile blade 609 to reset. After a delay by the electrical control system 16, the pneumatic spring check valve 6014 de-airs, the check block extends, and then the fresh bamboo shoot 22 with four cuts is manually removed.
