Disclosure of Invention

The utility model aims at providing a longan takes off nuclear machine in the aspect of simple structure, cost are low, operation.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a longan pitting machine comprises an upper support and a lower support, wherein the upper support is supported and fixed on the lower support through a support rod, a rotary platform capable of rotating around the center of the support rod is mounted on the support rod, at least three screw hole seats are fixed on the surface of the rotary platform, a pitting mechanism is arranged corresponding to each screw hole seat and comprises a pressing plate mechanism mounted on the upper support and an intubation cutter mechanism mounted on the lower support, the pressing plate mechanism (provided with a sliding table or other guide mechanisms or incapable of moving downwards) comprises a first stepping motor, a gravity sensor and a pressing plate, the first stepping motor is fixed on the upper support, the gravity sensor is fixed on an output shaft of the first stepping motor, the pressing plate is fixed below the gravity sensor, and the intubation cutter mechanism comprises a second stepping motor, The second stepping motor is fixed on the lower support, the screw rod is fixed on an output shaft of the second stepping motor, the sliding table is screwed on the screw rod and is installed on the guide rail through a side sliding groove, the guide rail is fixed on the lower support, and the cannula cutter is fixed on the sliding table.

The surface of the longan seat is provided with a pit for placing longan, and the center of the pit is provided with a through hole.

The kernel removing mechanism has the function of removing the kernels of the longans placed on the longan seat in the previous unit process, keeping the original structures of the shells and the meat and sending the shells and the meat to the next unit process. The method requires that in the working process of the working procedure, on one hand, the pulled out core is kept complete and can not leave the core fragments, on the other hand, the pulled out core can not bring out excessive meat so as to ensure the product yield, and in addition, the cut is required to be neat to create conditions for the next working procedure. The specific design takes about 4-5 seconds for one working cycle, so at least three sets of core removing mechanisms are designed to work simultaneously to improve the working efficiency.

In the denucleation mechanism, the pressing plate mechanism and the intubation knife mechanism can respectively and independently move up and down in a concentric manner and are driven by a stepping motor, and the main purpose is to automatically control the advancing position. The pipe inserting knife mechanism is used for pulling out longan seeds after longan is inserted; the pressing plate mechanism is used for pressing the longan, and the high-quality and high-efficiency operation of the working procedure is guaranteed. The gravity sensor is used for measuring the acting force of the pressing plate and the pipe inserting knife on the longan.

Compared with the prior art, the utility model, following advantage and beneficial effect have: simple structure, low cost, low labor intensity and high production efficiency in operation.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 to 4 are schematic diagrams of the operation of the present invention.

In the figure, 1-a second step motor, 2-a sliding table, 3-a pipe inserting cutter, 4-a screw eye seat, 5-longan, 6-a pressing plate, 7-a gravity sensor, 8-a first step motor, 9-an upper bracket, 10-a supporting rod, 11-a rotating platform, 12-a lower bracket, 13-a recess, 14-a through hole, 15-a screw rod and 16-a guide rail.

Detailed Description

Referring to fig. 1 to 4, the utility model provides a longan takes off nuclear machine, including upper bracket 9 and lower carriage 12, upper bracket 9 is supported by branch 10 and is fixed on lower carriage 12, install on branch 10 and to wind the rotatory rotary platform 11 of branch center rotation, the rotary platform is fixed with three longyan seat 4 on the surface, longyan seat 4 surface has a sunken 13 of placing longan 5, sunken 13 center has through-hole 14, be provided with a mechanism of taking off nuclear corresponding to every longyan seat 4, the mechanism of taking off nuclear includes the pressure plate mechanism of installing on upper bracket 9 and the intubate sword mechanism of installing on lower carriage 12, the pressure plate mechanism includes first step motor 8, gravity sensor 7 and pressure plate 6, first step motor 8 is fixed on upper bracket 9, gravity sensor 7 is fixed on the output shaft of first step motor 8, pressure plate 6 is fixed below gravity sensor 7, intubate sword mechanism includes second step motor 1, the first step motor is fixed on the lower carriage 12, the second step motor is fixed in the first step motor, Screw rod 15, slip table 2, guide rail 16 and intubate sword 3, second step motor 1 is fixed on lower carriage 12, and screw rod 15 is fixed on the output shaft of second step motor 1, and slip table 2 connects soon on screw rod 15 and installs on guide rail 16 through the side spout, and guide rail 16 is fixed on lower carriage 12, and intubate sword 3 is fixed on slip table 2.

The working process is as follows:

when the rotating platform 11 rotates to enable the longan seat 4 with the longan 5 to enter the working position, namely, the longan seat is located at the same center with the pipe inserting knife mechanism and the pressing plate mechanism and is stationary, the pipe inserting knife mechanism and the pressing plate mechanism are controlled to simultaneously start to move towards the longan in the middle, and when the pressing plate 6 is in downward contact with the longan 5 and applies certain pressure, the gravity sensor 7 controls the motor of the pressing plate mechanism to stop moving downward. Then the intubation knife 3 ascends to contact the longan shell and cut through the longan shell and the pulp to reach the surface of the nucleus, the pressure detected by the sensor is rapidly increased due to the hard nucleus, the PLC program enables the intubation knife 3 to continuously ascend for a certain stroke at the node, and the intubation knife 3 is inserted into the nucleus and then stops. The stroke is determined in advance, so that the intubation knife 3 can not insert broken cores and can clamp the cores, and the longan cores can be completely taken out when the intubation knife 3 retreats. After completion, the intubation knife mechanism and the pressing plate mechanism simultaneously start to move in opposite directions and retract to the initial position for a period, as shown in fig. 2 to 4.
