Abstract

The utility model discloses a prawn deheading device which comprises a rack, a feeding mechanism, a deheading mechanism and a discharging mechanism, wherein the feeding mechanism is perpendicularly fixed on the rack and comprises chain wheels, a chain and a plurality of V-shaped grooves; the deheading mechanism is arranged above the feeding mechanism and comprises a profiling clamp, a prawn head baffle, deheading rolls and a cylinder; and the discharging mechanism comprises discharging rods and a cylinder, and the discharging rods and the V-shaped grooves on working stations are arranged in parallel and connected onto the rack through the horizontally arranged cylinder. By arranging the deheading rolls, the prawn deheading device deheads a prawn, the prawn is pressed and discharged by controlling telescoping of the cylinder and rotating of motors, the processing operation can be simultaneously performed on the deheading stations and the discharging stations, the processing speed is high, the deheading effect is good, the structure is simple, and the device can be used for volume production of prawn processing.

Description

A kind of prawn head-removed device

Technical field

The utility model relates to a kind of prawn head-removed device, is particularly useful for the work of decaptitating that prawn is peeled off in technique in mechanical automation.

Background technology

In prawn shrimp head, contain heavy metal harmful, the processing of decaptitating of people multipair prawn when edible, the work of decaptitating of prawn is the important step that prawn mechanical automation is peeled off in technique, in follow-up prawn peeling operation, the head that removes prawn can prevent that the tissue of prawn head from polluting peeled shrimp.At present, the work of decaptitating of prawn, mostly by manually completing, in order to facilitate follow-up processing work, processes the relieved peeled shrimp of a kind of safety to the mankind, designs a kind of prawn head-removed device very necessary.

Summary of the invention

The utility model is to solve the unheading problem that prawn automation is peeled off in process, and a kind of prawn head-removed device is provided, and the prawn that this device can the transport directed prawn collator processing of decaptitating, to complete the follow-up processing work of peeling off.

The utility model solves the technical scheme that its technical problem adopts: a kind of prawn head-removed device, is mainly made up of frame, feed mechanism, decaptitate mechanism and shedding mechanism.Described feed mechanism is fixed in frame and is made up of sprocket wheel, chain and some V-type grooves, and described V-type groove is arranged on chain, V-type groove physical dimension determined by prawn size and under the driving of motor with chain movement, the prawn in V-type groove is transported to processing stations, described head cutter is set up the top in feed mechanism, by profiling jig, shrimp first speed plate, roller and the cylinder composition of decaptitating, described profiling jig be positioned at working position V-type groove directly over, be connected in frame by the cylinder of vertical layout, under the effect of described cylinder, realizing moves up and down compresses the prawn of working position, the dead ahead that described shrimp first speed plate is positioned at working position V-type groove keeps the distance of a shrimp length with V-type groove end face and aligns with described profiling jig, the described roller of decaptitating is placed between shrimp first speed plate and V-type groove near V-type groove end, by some groups side by side pony roll form, every group of pony roll relatively rotates the prawn work of decaptitating that realizes under the driving of motor, described shedding mechanism is made up of discharge arm and cylinder, and described discharge arm is arranged in parallel and is connected in frame by horizontally disposed cylinder with the V-shaped groove of locating working position, under the effect of described cylinder, seesaws, and realizes the discharging problem of prawn after decaptitating.

As optimization, described in decaptitate roller by some groups side by side pony roll form, the height that two pony rolls of every group are provided with helical raised that rotation direction is contrary and projection increases progressively gradually, the every group of roller rotating speed of decaptitating is identical, opposite direction.

The beneficial effects of the utility model: this prawn head-removed device is by the work of decaptitating realizing prawn that arranges of the roller of decaptitating, the rotation of the flexible and motor by control cylinder realize to prawn compress, discharging work, and can realize decaptitate station and unloading station and process operation simultaneously, process velocity is fast, it is effective to decaptitate, simple in structure, can be used in prawn and be processed into batch production.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is structural design drawing of the present utility model.

In figure: 1, motor I; 2, V-type groove; 3, discharge arm; 4, cylinder I; 5, profiling jig; 6, cylinder II; 7, sprocket wheel; 8, the roller of decaptitating; 9, shrimp first speed plate; 10, chain; 11, frame; 12, motor II.

The specific embodiment

For the technical characterstic of this programme can be described, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Figure 1, the utility model is a kind of prawn head-removed device, is made up of frame, feed mechanism, decaptitate mechanism and shedding mechanism.Each part is assembled in frame according to the design drawing shown in Fig. 1, arrange horizontally disposed cylinder I (4) and vertically arrange the program that cylinder II (6) is controlled, adjust the tensioning degree of chain (10) and the relative position of the roller of decaptitating (8), guarantee prawn the carrying out smoothly of work that decaptitate.

While carrying out this device to the work of decaptitating of prawn, the prawn transporting through directed collator is sent in V-type groove (2), motor I (1) drives V-type groove (2) motion, when when shrimp head touches shrimp first speed plate (9), shrimp body comes into line and moves under profiling jig (5) in V-type groove, profiling jig (5) moves downward and the shrimp body coming into line is clamped under the effect of cylinder II (6), motor II (12) drives the roller (8) of decaptitating to make its rotation by sprocket wheel (7), squeeze out and make shrimp head to fall into gathering-device on shrimp head, chain (10) drives V-type groove (2) to move forward, after arriving unloading station, pause the several seconds, discharge arm (3) is released the prawn decaptitating V-type groove (2) and is collected under the effect of cylinder I (4), so far, complete the work of decaptitating.
