Description

Technical Field

[0001] The invention relates to an agricultural product ingot-shaped engraving machine, belonging to the technical field of engraving machines. Background Art

[0002] In China, objects shaped like ingots symbolize wealth and good fortune, carrying profound cultural connotations. For a long period of history, ingots were indispensable in people's material lives, used for rewards, taxes, and transactions, and were a symbol of wealth. Furthermore, they are inextricably linked to Chinese folk customs and practices, carrying on traditional Chinese culture while serving as a symbol of prosperity and prosperity for the people, seeking blessings, happiness, and peace in autumn.

[0003] Foods shaped like ingots are very popular in the market, but most of the existing ingot-shaped foods are either hand-carved by chefs or produced by grinding the ingredients into powder and then using molds. The manual carving method not only requires a high level of carving skills from the chefs, but also has low carving efficiency and cannot form an industrialized production model. The method of grinding and then using molds destroys the original structure and nutritional value of the ingredients. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the present invention provides an agricultural product ingot-shaped engraving machine.

[0005] The technical solution of the present invention for solving the above-mentioned technical problems is as follows: it includes a frame, and a conveying device, a carving frame, a rotary carving device for carving the raised structure in the middle of the ingot, an outline carving device, a first driving mechanism and a second driving mechanism installed on the frame; the conveying device is arranged at the lower part of the frame, and a plurality of material discharge troughs are arranged at intervals on the conveying device, and the conveying device can intermittently move in the horizontal direction under the drive of the first driving mechanism; the carving frame is horizontally installed on the frame and located at the upper part of the conveying device, and the carving frame can move up and down under the drive of the second driving mechanism; the rotary carving device and the outline carving device are sequentially installed on the carving frame along the direction of material conveying; the rotary carving device includes a rotary driving device and a rotary carving knife, and one end of the rotary carving knife is connected to the output shaft of the rotary driving device.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the contour carving device includes a longitudinal beam, a knife arm, a shovel bucket, a support leg and an articulated arm. The longitudinal beam spans longitudinally above the conveying device of the frame through the support leg. One end of the knife arm is rotatable around the axis of the longitudinal beam and is connected to the longitudinal beam. The other end of the knife arm is connected to the shovel bucket. One end of the articulated arm is hinged to the knife arm, and the other end of the articulated arm is connected to the carving frame. When the carving frame moves up and down, the shovel bucket is driven to move through the articulated arm, and the shovel bucket makes a reciprocating up and down arc motion.

[0008] The beneficial effect of adopting the above further solution is that the carving frame drives the shovel bucket to move in an upward and downward arc shape, which will not cause the knife to get stuck and improve the carving efficiency.

[0009] Furthermore, it also includes a pressing and positioning device, which is installed on the engraving frame in the conveying direction facing the blank and is located at a position where the blank can pass first.

[0010] The beneficial effect of adopting the above further solution is that by adding a compacting and positioning device in front of the rotary engraving device, the blank can be compacted in the discharge trough before rotary engraving to prevent the blank from moving in the discharge trough or falling out of the discharge trough during the engraving process.

[0011] Furthermore, it also includes a dual-axis output drive mechanism, and the first drive mechanism and the second drive mechanism are respectively connected to the first output shaft and the second output shaft of the dual-axis output drive mechanism.

[0012] The beneficial effect of adopting the above further solution is that the dual-axis output drive mechanism drives the first drive mechanism and the second drive mechanism simultaneously, achieving a linkage effect of the first drive mechanism and the second drive mechanism, with a simple structure and economical applicability.

[0013] Furthermore, the conveying device includes a rotatable gear shaft mounted on a frame, a conveying gear mounted on the gear shaft, and a conveying chain / belt meshing with the conveying gear. The multiple discharge troughs are hinged on the conveying chain / belt, and the first driving mechanism drives the gear shaft to perform unidirectional intermittent rotational motion.

[0014] The beneficial effect of adopting the above further scheme is that the discharge trough is connected to the chain by an articulated manner, so that the discharge trough can be flipped at the end of the conveying device, making it convenient for the processed products to fall off the discharge trough; the first driving mechanism drives the gear shaft to perform unidirectional intermittent rotational motion. When the blank reaches the workstation, the gear shaft stops rotating, the conveying stops, and the engraving device processes the blank. After the processing is completed, the gear shaft continues to rotate, the conveying device starts to move forward, and the semi-finished blank is conveyed to the next processing station.

[0015] Furthermore, the first driving mechanism includes an active transmission mechanism, a first connecting rod mechanism and a driven transmission mechanism, the first connecting rod mechanism includes a first connecting rod and a second connecting rod, the first connecting rod is fixedly connected to the first driven wheel and rotates synchronously, one end of the second connecting rod is hinged to the first connecting rod, and the other end is hinged to the driven transmission mechanism, the active transmission mechanism is connected to the first output shaft of the dual-axis output drive mechanism, and the driven transmission mechanism is connected to the gear shaft.

[0016] The beneficial effect of adopting the above further solution is that it can not only realize the function of the first driving mechanism to intermittently move the conveying device in the horizontal direction, but also indirectly realize the linkage function with the second driving mechanism, the braking mechanism and the lever mechanism.

[0017] Furthermore, the second driving mechanism includes at least one eccentric bearing, wherein the inner ring of one of the eccentric bearings is connected to the second output shaft of the dual-axis output driving mechanism, the outer ring of the eccentric bearing is hinged to the engraving frame, and the outer rings of the remaining eccentric bearings are hinged to the engraving frame.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the outer ring of the eccentric bearing is hingedly connected to the engraving frame. When the eccentric bearing rotates, it can drive the engraving frame to move up and down but not forward and backward. The remaining outer ring of the eccentric bearing is hingedly connected to the engraving frame to ensure the balance of the lifting frame.

[0019] Furthermore, a braking mechanism is included, which is used to prevent the conveying device from running forward or reverse due to external force when the conveying stops and the engraving is performed.

[0020] The braking mechanism includes a gear set linked to the active transmission mechanism, a braking gear, a first braking pawl, and a second braking pawl. The gear set includes a second driven gear and a third driven gear that mesh with each other. The braking gear is mounted on the gear shaft. The first braking pawl is hinged to the frame at one end and engaged with the braking gear at the other end, thereby limiting counterclockwise rotation of the conveyor. The second braking pawl is hinged to the frame at one end and engaged with the braking gear at the other end, thereby limiting clockwise rotation of the conveyor.

[0021] The second braking pawl is connected to the third driven gear through a second connecting rod mechanism, so that the braking effect of the second braking pawl is linked to the conveying process of the conveying device. The second connecting rod mechanism includes a third connecting rod, a fourth connecting rod and a fifth connecting rod. One end of the third connecting rod is eccentrically hinged to the third driven gear, the other end of the third connecting rod is hinged to one end of the fourth connecting rod, the other end of the fourth connecting rod is connected to the fifth connecting rod through a sliding sleeve, and the fifth connecting rod is vertically fixedly connected to the second braking pawl, so that the third driven gear drives the second braking pawl to perform an arc-shaped up and down rotation around the intersection point.

[0022] The beneficial effect of adopting the above further solution is that the braking mechanism can prevent the conveyor device from rotating forward or backward due to external forces when conveying stops and engraving is in progress. The second braking pawl is connected to the third driven gear via a second linkage mechanism, thereby interlocking the second braking pawl with the conveyor device during the conveying process. When the active transmission mechanism drives the conveyor device to convey, the second braking pawl rises upward under the action of the third driven gear and the second linkage mechanism and separates from the braking gear. When the conveyor device stops conveying and engraving is in progress, the second braking pawl descends under the action of the third driven gear and the second linkage mechanism and engages with the braking gear.

[0023] Furthermore, the active drive mechanism includes a driving wheel, a first driven wheel and a first rotating shaft, the driving wheel is connected to the first output shaft of the dual-axis output drive mechanism, the first rotating shaft is installed on the frame through a positioning bearing, the first driven wheel is installed on the first rotating shaft, and the driving wheel and the first driven wheel are connected by a transmission chain / belt.

[0024] The beneficial effect of adopting the above further scheme is that the active drive mechanism includes a driving wheel, a first driven wheel and a first rotating shaft, which not only meets the size requirements of the engraving machine, but also can realize the linkage function of the first drive mechanism and the second drive mechanism, the braking mechanism and the lever mechanism, and the design is ingenious.

[0025] Furthermore, the driven transmission mechanism includes a rack or chain, a transmission gear, a ratchet and a driving pawl. The rack or chain can be arranged on the frame and can move up and down in the vertical direction. The rack or chain is hinged to the first connecting rod mechanism. The rack or chain is engaged with the transmission gear. The transmission gear is rotatably mounted on one end of the gear shaft. The ratchet is fixedly mounted on the gear shaft. One end of the driving pawl is fixed on the transmission gear, and the other end is engaged with the ratchet.

[0026] The beneficial effect of adopting the above further scheme is that the active drive mechanism includes a driving wheel, a first driven wheel and a first rotating shaft, which not only meets the size requirements of the engraving machine, but also can realize the linkage function of the first drive mechanism and the second drive mechanism, the braking mechanism and the lever mechanism, and the design is ingenious.

[0027] Furthermore, the frame is provided with a finished product outlet and a residual material outlet at the end of the conveying device.

[0028] The beneficial effect of adopting the above further solution is that the discharge port includes a finished product outlet and a residual material outlet, and the engraved parts are discharged from the corresponding outlets respectively, saving the step of re-sorting and improving work efficiency.

[0029] The beneficial effects of the present invention are:

[0030] 1.

Eccentric bearings are designed at both ends of the engraving frame 3 to prevent the engraving frame 3 from tilting and ensure that the engraving machine 3 moves up and down smoothly.

[0066] The steps for engraving machine to process the shape of ingot are as follows:

[0067] The first step is cutting and placing the root vegetables. First, the root vegetables are cut into rectangular / cuboid structures and the cut semi-finished blanks are clamped into the discharge chute 205. The conveyor device 2 drives the semi-finished blanks forward. Driven by the first drive mechanism 6, the conveyor device 2 can intermittently move horizontally. During the conveying process, the drive motor 8 drives the carving frame and the pressing and positioning device 19, the rotary carving device 4, and the contour carving device 5 on the carving frame to move upward.

[0068] The second step is compaction and positioning: compacting the semi-finished blank into the discharge trough. When the discharge trough 205 containing the semi-finished blank moves to the position directly below the compaction and positioning device 19, the conveying device 2 stops running, and the compaction and positioning device 19 moves downward to compact the blank into the discharge trough 205, preventing the blank from moving or falling out of the discharge trough 205 during the engraving process. After compaction in the discharge trough 205, the compaction and positioning device 19 rises, and the semi-finished blank continues to move to the next station.

[0069] The third step is rotary engraving: the raised structure in the middle of the semi-finished blank is engraved. After being compacted in the discharge chute 205, the blank continues to move directly below the rotary engraving device. The conveyor device 2 stops running, and the rotary drive device 401 drives the rotary engraving tool 402 to rotate, engraving the raised structure in the middle of the semi-finished blank. After engraving is completed, the rotary engraving device 4 rises, and the semi-finished blank continues to move to the next station.

[0070] The fourth step is carving the left side contour. The semi-finished blank continues to move forward under the drive of the conveyor 2. When it reaches the bottom of the left shovel bucket 504, the conveyor 2 stops and the left shovel bucket 504 moves down to carve the left side contour of the blank. After carving is completed, the semi-finished blank continues to move to the next station.

[0071] Step 5: Carve the right side contour. The semi-finished blank continues to move forward driven by the conveyor 2. When it reaches below the right shovel bucket 505, the conveyor 2 stops and the right shovel bucket 505 moves downward to carve the right side contour of the blank. After carving is completed, the conveyor 2 continues to move forward, the discharge chute 205 flips, and the finished product and residual material are discharged through the finished product outlet 1701 and residual material outlet 1702 respectively.

[0072] Based on the first, second, or third embodiment, the present invention further provides a fourth embodiment. In this fourth embodiment, the agricultural product ingot-shaped engraving machine further includes a brake mechanism 10, which is used to prevent the conveying device from rotating forward or backward due to external force when the conveying stops and the engraving is performed.

[0074] The second braking pawl 14 is connected to the third driven gear 1102 through a second connecting rod mechanism 15, so that the braking effect of the second braking pawl 14 is linked to the conveying process of the conveying device 2. The second connecting rod mechanism 15 includes a third connecting rod 1501, a fourth connecting rod 1502 and a fifth connecting rod 1503. One end of the third connecting rod 1501 is eccentrically hinged to the third driven gear 1102, and the other end of the third connecting rod 1501 is hinged to one end of the fourth connecting rod 1502. The other end of the fourth connecting rod 1502 is connected to the fifth connecting rod 1503 through a sliding sleeve. The fifth connecting rod 1503 is vertically fixed to the second braking pawl 14, so that the third driven gear 1102 drives the second braking pawl 14 to perform an arc-shaped up and down rotation around the intersection.

[0075] The braking process is as follows: the second brake pawl 14 is connected to the third driven gear 1102 through the second connecting rod mechanism 15, so that the second brake pawl 14 is linked to the conveying process of the conveying device 2. When the active transmission mechanism drives the conveying device 2 to convey, the second brake pawl 14 rises upward under the action of the third driven gear 1102 and the second connecting rod mechanism 15 and separates from the brake gear 12. When the conveying device 2 stops conveying and performs engraving, the second brake pawl 14 descends under the action of the third driven gear 1102 and the second connecting rod mechanism 15 and engages with the brake gear 12.

[0076] The discharge port 16 includes a finished product outlet 1601 and a residual material outlet 1602. The finished product outlet 1601 and the residual material outlet 1602 are arranged on the frame 1 at the end of the conveying device 2. The engraved parts are discharged from the corresponding outlets respectively, saving the step of re-sorting and improving work efficiency.

[0077] The steps for engraving machine to process the shape of ingot are as follows:

[0078] The first step is cutting and placing the root vegetables. First, the root vegetables are cut into rectangular / cuboid structures and the cut semi-finished blanks are clamped into the discharge chute 205. The conveyor device 2 drives the semi-finished blanks forward. Driven by the first drive mechanism 6, the conveyor device 2 can intermittently move horizontally. During the conveying process, the drive motor 8 drives the carving frame and the pressing and positioning device 19, the rotary carving device 4, and the contour carving device 5 on the carving frame to move upward.

[0079] The second step is to compact and position the semi-finished blank in the discharge trough. When the discharge trough 205 containing the semi-finished blank moves to the position directly below the compacting and positioning device 19, the conveying device 2 stops running, the brake mechanism 10 brakes, and the compacting and positioning device 19 moves downward to compact the blank in the discharge trough 205 to prevent the blank from moving or falling out of the discharge trough 205 during the engraving process. After compaction in the discharge trough 205, the compacting and positioning device 19 rises, the brake mechanism 10 releases the brake, and the semi-finished blank continues to move to the next station.

[0080] The third step is rotary engraving: the raised structure in the middle of the semi-finished blank is engraved. After being compacted in the discharge chute 205, the blank continues to move directly below the rotary engraving device. The conveyor device 2 stops, the brake mechanism 10 brakes, and the rotary drive device 401 drives the rotary engraving tool 402 to rotate, engraving the raised structure in the middle of the semi-finished blank. After engraving is completed, the rotary engraving device 4 rises, the brake mechanism 10 releases the brake, and the semi-finished blank continues to move to the next station.

[0081] Step 4: Carving the left side contour. The semi-finished blank continues to move forward driven by the conveyor 2. When it reaches below the left shovel bucket 504, the conveyor 2 stops, the brake mechanism 10 brakes, and the left shovel bucket 504 moves downward to carve the left side contour of the blank. After carving is completed, the brake mechanism 10 releases the brake, and the semi-finished blank continues to move to the next station.

[0082] Step 5: Carve the right side contour. The semi-finished blank continues to move forward driven by the conveyor 2. When it reaches below the right shovel bucket 505, the conveyor 2 stops, the brake mechanism 10 applies the brake, and the right shovel bucket 505 moves downward to carve the right side contour of the blank. After carving is completed, the brake mechanism 10 releases, the conveyor 2 continues to move forward, the discharge chute 205 flips, and the finished product and residual material are discharged through the finished product outlet 1701 and residual material outlet 1702 respectively.

[0083] In addition, those skilled in the art know that the present invention can be used not only for carving agricultural products in the shape of ingots, but also for other objects that can be carved, such as adobes, etc., as long as they are suitable for the engraving machine disclosed in the present invention, and no further details will be given here.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
