Description

Technical Field

[0001] The invention belongs to the technical field of vegetable processing machinery, and in particular relates to a double-stage core removing device for cabbage vegetables with an inverted arch cutting track. Background Art

[0002] Heading vegetables are a type of cruciferous vegetable that is rich in various nutritional values ​​and is very popular among consumers. The market demand is increasing rapidly. Figure 10 As shown, head vegetables consist of a main rhizome A, florets B, and buds C. During food preparation, most people remove the main rhizome (core), leaving the florets and buds. Therefore, core removal of head vegetables not only meets consumer needs and saves time, but also facilitates packaging, storage, and transportation, saving transportation costs.

[0003] Existing processing devices for cabbage vegetables mainly adopt a single-stage process, which has problems such as incomplete removal of the main rhizome (core), low processing efficiency, high waste of raw materials, and oversized devices. Patent application number 201711372965.3 discloses a two-stage conveyor-type automatic cutting and coring production line for cabbage vegetables, including a frame, a feeding device, a conveying device, a rotating device, a guide device, an isolation device, an arc guide plate, a cutting device, and an arc-shaped flower cutting knife. The patent uses a power source to simultaneously realize the circular movement and closed cutting of the hemispherical tool. Since the main rhizome (core) of cabbage vegetables is cylindrical, the use of a single-stage process will inevitably lead to the miscutting of some small flower stems, resulting in waste of raw materials. Based on the above situation, it is very important to design a double-stage coring device for cabbage vegetables with an inverted arch cutting trajectory that adopts a double-stage process and can reduce raw material waste. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the above-mentioned background technology and to provide a double-stage coring device for head vegetables with an inverted arch cutting trajectory, which can accurately cut off the main rhizome of the head vegetables and reduce the waste of raw materials.

[0005] The technical solution of the present invention is:

[0006] A dual-stage coring device for cabbage vegetables with an inverted arch cutting path is characterized in that the device comprises a frame, a secondary coring mechanism for separating the florets of cabbage vegetables and removing the main rhizome of cabbage vegetables, and a conveying mechanism for horizontally transporting cabbage vegetables;

[0007] The secondary core removing mechanism includes a core remover and a lifting cylinder that drives the core remover to move up and down.

[0008] The core remover includes a core removing frame, a core removing cylinder fixed on the core removing frame, a cutting cylinder fixed to the core removing frame through a cutting bracket, an annular cutter head arranged on the piston rod of the cutting cylinder, a pair of arc-shaped blades positioned on the core removing frame that can be opened and closed, and a core removing connecting rod that transmits power from the core removing cylinder to drive the arc-shaped blades to open and close.

[0009] The piston rod of the lifting cylinder is fixed to the core removing frame; the core removing frame can be vertically slidably positioned on the frame; the two ends of the core removing connecting rod are rotatably hinged on the arc blade and the piston rod of the core removing cylinder respectively.

[0010] The secondary core removal mechanism further includes a core removal plate and a translation cylinder for driving the core removal plate to move horizontally.

[0011] The conveying mechanism includes a crawler conveyor and a plurality of trays arranged on a conveyor belt of the crawler conveyor.

[0012] The frame includes a first frame, and the secondary core removal mechanism is arranged on the first frame; the conveyor passes through the first frame, and the secondary core removal mechanism is arranged above the crawler conveyor.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention uses a cylinder to drive the arc-shaped blade to open and close to cut off the main root (core), with a simple structure and easy control;

[0015] 2. The present invention carries out the core removal process through a two-stage process, first separating the florets on both sides of the main rhizome (core), and then digging out the main rhizome (core), which can reduce the phenomenon of miscutting and thus reduce the waste of raw materials;

[0016] 3. The present invention integrates the arc-shaped blade and the annular cutter head into the core remover, thereby improving the spatial integration of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1 As shown, a double-stage coring device for head vegetables (taking broccoli as an example) with an inverted arch cutting trajectory includes a frame 1, a secondary coring mechanism 2, and a conveying mechanism 3.

[0037] The frame is made of square tubes welded together. The frame includes a first frame 101. Figure 1 As shown, the secondary core removing mechanism is arranged on the first frame, the conveying mechanism passes through the first frame, and the secondary core removing mechanism is arranged above the conveying mechanism.

[0038] The conveying mechanism includes a crawler conveyor 301 and a plurality of trays 303 mounted on a conveyor belt 302 of the crawler conveyor, with the trays spaced apart. The inner walls of the trays are curved (matching the shape of the buds of the cabbage vegetables) to ensure that the cabbage vegetables can be stably placed upside down in the trays for subsequent processing.

[0039] like Figure 5 As shown, the secondary coring mechanism includes a corer, a lifting cylinder 201, a core removal plate 221, and a translation cylinder 222. The lifting cylinder is used to drive the corer up and down. The lifting cylinder is fixed to the first frame, and the corer is positioned vertically and slidably on the first frame. The piston rod of the lifting cylinder is fixed to the corer's core removal frame.

[0040] like Figure 3 As shown, the core remover includes a core removing frame 211 , a core removing cylinder 212 , a cutting bracket 213 , a cutting cylinder 214 , an annular cutter head 215 , an arc-shaped blade 216 , and a core removing connecting rod 217 .

[0041] A vertically arranged sliding column 102 is provided on the first frame, and the core removing frame can slide vertically along the sliding column. The piston rod of the lifting cylinder is fixed to the core removing frame, and the core removing cylinder is fixed to the core removing frame. A pair of arc-shaped blades can be rotatably positioned on the core removing frame, and a connecting frame 218 is provided on the piston rod of the core removing cylinder. The two ends of the core removing connecting rod are rotatably hinged on the connecting frame and the arc-shaped blades respectively.

[0042] The cutting bracket is fixed on the two side support plates 219 of the core removal frame, and the cutting cylinder is fixed to the cutting bracket. The piston rod of the cutting cylinder is provided with an annular cutter head (arc blades are located on both sides of the annular cutter head). When the piston rod of the cutting cylinder is extended, the annular cutter head is driven vertically downward ( Figure 8 As shown), when the piston rod of the cutting cylinder is retracted, the annular cutter head is driven vertically upward ( Figure 7 To avoid interference, the annular cutter head can only move vertically when the curved blades are opened.

[0043] like Figure 4 As shown, the annular cutter head is fixed to the piston rod of the cutting cylinder via a plurality of L-shaped connecting rods 231. The annular cutter head and the L-shaped connecting rods are connected as a whole, and the L-shaped connecting rods are connected to the piston rod of the cutting cylinder via bolts. The annular cutter head has a blade angle of 8° and is made of 2Cr13.

[0044] Both ends of the arc blade are rotatably positioned on the two side support plates of the core removal frame, and the arc blade is closed when the piston rod of the core removal cylinder is extended ( Figure 9 The curved blade is in the shape of a grab bucket. When it is closed, the curved blade plays a role of cutting and grabbing. When the piston rod of the core cylinder is retracted, the curved blade opens ( Figure 7 The core removal plate is arranged below the core remover, and the translation cylinder is fixed to the first frame and is used to drive the core removal plate to move horizontally.

[0045] The arc-shaped blade has an edge angle of 15° and is made of 2Cr13. A position sensor 231 for detecting the tray (heading vegetables) is also provided on the first frame.

[0046] The present invention also includes a controller (omitted in the figure), which is electrically connected to the crawler conveyor, the lifting cylinder, the coring cylinder, the cutting cylinder, the translation cylinder, and the position sensor. The controller, the crawler conveyor, the lifting cylinder, the coring cylinder, the cutting cylinder, the translation cylinder, and the position sensor are all prior art and can be purchased externally.

[0047] The working principle of the present invention is as follows:

[0048] 1. The external device places the head vegetables one by one into the tray; the head vegetables are placed on the tray in an inverted position, with the buds facing downwards and the main root (core) facing upwards;

[0049] 2. The conveying mechanism drives the cabbage vegetables to move horizontally from right to left (the conveyor belt of the crawler conveyor rotates in the counterclockwise direction);

[0050] 3. When the position sensor detects that the tray is just below the corer, the secondary corer mechanism is activated and the conveying mechanism is paused: the lifting cylinder is activated to drive the corer downward; the cutting cylinder is activated, the annular blade moves downward (the arc blade opens), and the small flower stems on both sides of the main rhizome (core) are cut and separated; the cutting cylinder is reset, and the annular blade moves upward, away from the heading vegetables; the corer cylinder is activated, and the arc blade closes, cutting and grabbing the main rhizome (core) ( Figure 13 The dotted line in the figure is the cutting trajectory); the lifting cylinder is activated, driving the core remover to move upward to remove the main root (core);

[0051] 5. The conveying mechanism starts; at the same time, the translation cylinder starts, and the core removal plate moves to the bottom of the core remover; the core removal cylinder resets, the curved blade opens, and the main root (core) falls onto the core removal plate and is discharged to the side for separate collection; the translation cylinder resets;

[0052] 6. Return to step 2, and the present invention is carried out in a cycle according to the above steps.

[0053] like Figure 15 As shown, in the prior art (201711372965.3 A two-stage conveyor type broccoli automatic cutting and core removal production line), a single-stage process track ( Figure 15 The double-stage process of the present invention reduces the possibility of miscutting by first separating the florets on both sides of the main rhizome and then cutting the main rhizome.
