technical field

The invention relates to food processing machinery and equipment, in particular to equipment for coring and processing fresh lotus seeds.

Background technique

The coring of fresh lotus seeds is mainly divided into traditional manual coring and mechanical coring. Manual coring mainly uses fine needles and other tools to pick out the lotus cores of fresh lotus seeds. This method is labor-intensive and low in work efficiency. The operator often suffers hand injuries, and the lotus cores taken out are incomplete or the lotus seeds are broken. , poor processing quality. Moreover, the existing fresh lotus seed mechanical coring equipment currently on the market needs to be graded before coring, and is accompanied by problems such as incomplete lotus cores, crushed lotus seeds, and sorting of lotus cores and lotus seeds after coring. .

The core-through mechanism is that a driving sprocket 9 and a driven sprocket 11 are installed above the frame 1, and the stepper motor 3 drives the sprocket driving shaft 8 on the driving sprocket 9 through a synchronous belt 4 to rotate. The roller chain 12 that conveys the lotus seeds 28 and realizes the axis of the lotus seeds 28 to be parallel to the core-through punch 27 is installed on the sprocket. The rollers 13 are constantly rolling while moving, so that the lotus seeds 28 between the adjacent rollers 13 are adjusted from the initial irregular placement to the direction of the lotus cores parallel to the axis of the core punch 27, ensuring accurate core penetration. Reliable, the two adjacent rollers 13 of the roller chain 12 and the pressure roller 31 above them are distributed in a zigzag shape;

Roller chain support plate 18 is housed below roller chain 12, and crank mounting block 15 is equipped with below roller chain support plate 18, and one end of crank 29 is hinged on crank mounting block 15, and the other end of crank 29 and connecting rod 30 One end of the connecting rod 30 is hinged, and the other end of the connecting rod 30 is hinged with the pressure wheel mounting block 32; the roller chain support plate 18 is equipped with a silica gel plate 19.

The aforementioned pressure wheel 31 is installed under the pressure wheel mounting block 32, the upper end of the pressure wheel mounting block 32 is connected with the slide bar 33, the upper end of the slide bar 33 has a rectangular groove, and the horizontal plate 38 passes through the slide bar rectangular grooves of multiple sets of core-through mechanisms , and is fixedly connected with the ejector rod 35 of the ejector rod cylinder 36, and the ejector rod cylinder 36 drives the horizontal plate 38 and the slide bar 33 to move up and down through the ejector rod 35; the rectangular groove of the slide bar 33 and the transverse plate 38 have sufficient The gap can adapt to lotus seeds 28 of different sizes and cause changes in the vertical direction. When the push rod 35 moves down to the limit position, the pressure wheel 31 and the lotus seeds of different sizes will move under the gravity of the slide rod 33 and the through-core cylinder 26. 28 contacts, and the two rollers 13 of the pinch wheel 31 and the roller chain 12 clamp the lotus seeds 28 together;

A color sensor 21 is installed on one side of the aforementioned crank mounting block 15, and the front and back of the lotus seeds 28 are identified by the color sensor 21. A through-core cylinder 26 is respectively installed on both sides of the roller chain 12, and the through-core cylinder 26 is mounted on the through-core cylinder mounting plate 25, the through-core cylinder mounting plate 25 and the through-core cylinder support seat 23 are hinged together by two sets of struts 24, and one end of the through-core cylinder mounting plate 25 is mounted on the crank 29 and the connecting rod 30 on the bearing at the hinge, and move with the up and down movement of the slide bar 33; thus the through-core cylinder 26 can automatically adjust the height of the through-core cylinder 26 according to the size of the lotus seeds 28, so that the center of the through-core punch 27 is always in line with the setting The centers of the through-core processing areas coincide to ensure the accuracy of through-core processing.

The aforementioned color mark sensor 21 is connected to a PLC controller 42 , and the PLC controller 42 is connected to control the through-core cylinder 26 , the ejector cylinder 36 and the stepper motor 3 .

The working process of a kind of full-automatic fresh lotus seed corer of the present invention is as follows: lotus seeds 28 are poured in from the feed hopper 39 above the feed hopper 39 frame 1, and the lotus seeds 28 fall into the feed chute 40 under the action of gravity, and the feed chute The structure of 40 ensures that there is and only one lotus seed 28 falls on the groove between the two rollers 13 of the roller chain 12, because the stepper motor 3 drives the lotus seed on the roller chain 12 through the rotation of the driving sprocket 9 28 moves forward, while the roller chain 12 is moving forward, due to the friction between the roller chain 12 and the silica gel plate 19 below, the roller 13 is constantly rolling while moving, so that the lotus seeds 28 between adjacent rollers 13 The direction of the lotus core is adjusted from the initial irregular placement to be parallel to the axis of the through-core punch 27, so as to ensure the accuracy and reliability of the through-core. When the lotus seeds 28 move to the position of the identification mechanism, the color code sensor 21 identifies the front and back of the lotus seeds 28 and sends the identification signal to the PLC controller 42. The lotus seeds continue to move forward with the roller chain 12, and move to Two rollers 13 on 12 and pinch roller 31 form through core processing area. The stepping motor 3 stops rotating, and the push rod cylinder 36 moves downward, and the slide bar 33 and the cross plate 38 slide downward under the action of the push rod cylinder 36, and the slide rod 33 slides down until the lotus seeds 28 are compressed, and the push rod 35 Continue down to the limit with the horizontal plate 38 , the horizontal plate 38 at this moment keeps a certain gap with the rectangular groove on the upper end of the slide bar, so the pressure roller 31 can well compress the lotus seeds 28 of various sizes. At this time, the two rollers 13 on the pressure wheel 31 and the roller chain 12 clamp the lotus seeds 28, because the through-core cylinder 26 is installed on the through-core cylinder mounting plate 25, and the through-core cylinder mounting plate 25 and the through-core cylinder support seat 23 Two sets of struts 24 are hinged together, and one end of the through-core cylinder mounting plate 25 is mounted on the bearing at the hinge joint between the crank 29 and the connecting rod 30, and moves with the up and down movement of the slide rod 33; thereby enabling the through-core cylinder 26 to According to the size of the lotus seeds 28, the height of the core-through cylinder 26 is automatically adjusted, so that the center of the core-through punch 27 always coincides with the center of the set core-through processing area, ensuring the accuracy of the core-through processing. At this time, the PLC controller 42 recognizes the identification signal sent by the color code sensor 21, and sends out an action signal to make the core-through cylinder 26 located at one end of the lotus seed 28 move, and the core-through cylinder 26 drives the core-through punch 27 to quickly and accurately press the The lotus core is rushed out, and the lotus core falls on the lotus core discharge hopper 6 located directly below the core-through mechanism. The PLC controller 42 controls the action of the core-through cylinder 26, so that the core-through punch 27 quickly returns to complete the core-through operation, and the ejector rod cylinder 36 Through the horizontal plate 38, the slide bar 33 is raised to the upper limit position, the stepper motor 3 rotates, and the multi-roller chain 12 of the lotus root is transported to the position of the lotus seed discharge hopper 5, and falls into the lotus seed discharge hopper 5. The cyclic action of the whole mechanism is controlled by the PLC controller 42 to act on each air cylinder and stepping motor.
