Description

Technical Field

[0001] The invention relates to a peeler capable of peeling a pineapple and removing the pineapple eye, belonging to the technical field of fruit processing equipment. Background Art

[0002] Pineapple is a kind of fruit that people like, and pineapple is particularly rich in vitamin content, so it has extensive nutritional value and market value. Pineapple peel is closely connected with flesh, and there are many pineapple eyes and sharp edges on pineapple peel, so it is difficult to peel pineapple. There are two types of existing pineapple peeling methods, the first type is manual cutting, and the second type is a simple peeling machine. During manual cutting, first use a double-layer knife to cut the pineapple epidermis, and then use a small tweezer to remove the pineapple eyes one by one. This method is time-consuming, laborious, and inefficient, and the cutting is limited by personal experience and skills, and the finished product does not have a fixed form. When using a simple peeling machine for cutting, the pineapple is fixed on a bracket using a fixed rod, the knife handle is moved, and the fixed rod is rotated to peel horizontally. This method is wasteful, and the pineapple eyes must be removed one by one, which is difficult to promote and use. Therefore, it is very necessary to develop a processing device that can quickly remove pineapple peel and pineapple eyes to meet the needs of people eating pineapples. Summary of the invention

Under the action of the reduction motor 703, the eye removal knife rotates with the motor shaft of the reduction motor 703 to achieve the purpose of moving in the xy plane.

[0052] In the process of removing the pineapple peel, the peeling knife falls down, the eye-removing knife is put away, the cutting gear 503 rotates at a constant speed and makes a circular motion, the peeling knife is close to the pineapple peel, and the pineapple peel is removed during the rotation process. There are four peeling knives, which can remove the pineapple peel to the maximum extent. A pineapple has eight pineapple eyes, which are spiral-shaped. Four eye-removing knives are used. In the removal process, the cutting gear rotates slowly, cooperates with the up and down movement of the pineapple, and removes the pineapple eyes of the pineapple. It goes back and forth twice to remove all the pineapple eyes on the pineapple.

[0053] Figure 8It is shown that the cleaning and conveying part includes a lower drawer 207, a bevel baffle 801, and a slide rail 802. The bevel baffle 801 is located below the central circular hole of the lower partition 210. The lower part of the bevel baffle 801 is opposite to the lower drawer 207. The slide rail 802 is installed on both sides of the lower drawer 207. In addition to collecting cutting waste, the cleaning and conveying part is also designed with multiple compartments for placing tools, sundries, decorations, etc., which enhances the appearance and improves the space utilization. The lower drawer 207 of the collection mechanism is directly below the cutting tool, which can ensure that 100% of the falling waste falls into the lower drawer 207. The slide rails 802 are arranged on both sides of the lower drawer 207, which can easily and conveniently send out the waste and facilitate cleaning.

[0054] The motor of the present invention is a stepper motor, and its working principle is to convert the electric pulse signal into an open-loop control element of angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, which is called the "step angle". Its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, thereby achieving the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, thereby achieving the purpose of speed regulation.

[0055] The role of the stepper motor in the device is: in the process of cutting pineapple peel, the pineapple moves vertically up and down to ensure that the pineapple peel is cut cleanly. Therefore, the required speed is relatively slow and the movement of the tool is faster. In the process of cutting pineapple eyes, the movement of the pineapple and the speed of the eye-removing knife are relatively slow. Ordinary motors require too much current, and the speed is relatively fast and cannot be changed. Compared with ordinary motors, stepper motors have adjustable speed and are easy to control the speed to avoid cutting the pulp.

[0056] The chip controls the speed of each motor, as well as the forward and reverse rotation, to achieve the rotation and extension of the peeling knife, and the retraction and extension of the eye-removing knife set. Its working principle is: peeling: the chip controls the motor to rotate forward, and the clamping device transports the pineapple downward. At the same time, the chip controls the peeling knife to run at high speed until the pineapple is transported downward to the specified position. The chip controls the motor to reverse, and the clamping device transports the pineapple upward. At the same time, the chip controls the peeling knife to run at high speed until the pineapple is transported upward to the specified position. Removing "black eyes": the chip controls the eye-removing knife set to align the knife, and then controls the motor to rotate forward at low speed, and the clamping device slowly transports the pineapple downward. At the same time, the chip controls the tool clamping disk to rotate at low speed until the pineapple is transported downward to the specified position. The chip controls the knife set to retract, and then the chip controls the motor to reverse, and the clamping device transports the pineapple upward to the specified position, and the motor stops rotating.

[0057] Fig. 9The overall control diagram is displayed. The single-chip microcomputer U2 uses the MCU.SchDoc model to control the first, third, and fourth motors respectively, so that multiple motors can operate simultaneously. The second motor only rotates in one direction and does not need single-chip microcomputer control. It has a switch self-locking function.
