Description

Technical Field

[0001] This utility model relates to the field of persimmon peeling machine technology, specifically to a positioning mechanism for an automated persimmon peeling machine. Background Technology

[0002] Persimmon, also known as Zhu Guo, is the fruit of a deciduous tree belonging to the genus Diospyros in the family Ebenaceae. When processing persimmons into dried persimmons, they first need to be peeled. The traditional method in the industry is manual peeling, but this is time-consuming, labor-intensive, inefficient, and costly. Furthermore, uneven peeling results in inconsistent appearance and lowers the quality of the dried persimmons. Therefore, automated persimmon peeling machines have emerged.

[0003] Currently, automated persimmon peeling machines require a positioning mechanism to hold the persimmon in place when peeling it. To hold the persimmon in place and prevent it from slipping off the peeler during peeling, it is usually necessary to insert a rod into the persimmon or clamp it firmly at both ends. However, these fixing methods either cause the persimmon to break or prevent the end of the persimmon from being peeled smoothly, resulting in significant defects in the effectiveness of the machine. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for an automated persimmon peeling machine to address the aforementioned shortcomings in the technology.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Core components and working principle: This utility model relates to, for example Figures 1 to 7 The positioning mechanism of the automated persimmon peeling machine shown here has the core function of achieving stable, non-destructive fixation and precise centering of the persimmon through a combination of non-invasive adsorption and external auxiliary positioning. It can also drive the persimmon to rotate, so as to cooperate with the peeling blade to complete a comprehensive and uniform peeling operation. The mechanism adopts a dual-station design, with the upper station being the feeding and positioning station and the lower station being the peeling and automatic unloading station, which effectively improves production efficiency. The mechanism is mainly composed of a base plate (1), a fixed vertical plate (2), a rotating disk (3), an adsorption component, a movable plate (9), an auxiliary positioning component, and multiple power and adjustment components.

[0021] Specific implementation steps and the synergistic effect of each component: 1. Material loading and auxiliary positioning (upper workstation): Place the persimmon to be peeled at the adsorption head (5) at the front end of the upper adsorption tube (4).

[0022] The first motor (16) is started, driving the four clamping rods (10) to converge towards the center synchronously. The core function of these four clamping rods (10) is not to clamp forcefully, but to assist in positioning. They gently contact the persimmon from all sides to ensure that the central axis of the persimmon coincides with the central axis of the upper adsorption tube (4), thus achieving precise centering.

[0023] After centering is completed, start the negative pressure pump (6) connected to the upper adsorption tube (4). The negative pressure generated by the adsorption head (5) firmly adsorbs the persimmon stem part. To ensure adsorption, the persimmon stem part can be ground flat first.

[0024] After the adsorption stabilizes, the first motor (16) reverses and drives the four clamping rods (10) to retract synchronously, detaching from the persimmon and making room for subsequent rotation. At this point, the upper station has completed the loading and positioning of the persimmon.

[0025] 2. Workstation switching: The second motor (18) is started. The second motor (18) drives the second gear (21) fixed to the rotating disk (3) through the first rotating rod (19) and the first gear (20), causing the rotating disk (3) to rotate 180 degrees. At this time, the persimmons that have been positioned are transferred from the upper station to the lower peeling station, while the empty upper station is moved back to the original loading position, ready for the loading and positioning of the next persimmon. This design realizes the parallel operation of loading and unloading and peeling.

[0026] 3. Rotary peeling (lower station): The persimmons located at the lower peeling station have been reliably adsorbed by negative pressure.

[0027] Start the third motor (22) corresponding to this workstation. The third motor (22) drives the adsorption tube (4) below and the persimmon to rotate around its own axis (rotation) through the meshing of the second rotating rod (23), the third gear (24) and the fourth gear (25).

[0028] Fixed peeling blades can be pre-installed at the front and back of the persimmon (relative to the view in the attached diagram). The rotation of the persimmon allows its surface to pass over the blades in all directions without any blind spots, thus achieving uniform and thorough automated peeling. This is existing technology and will not be elaborated upon here.

[0029] 4. Automatic material unloading: After peeling, stop the negative pressure pump (6) connected to the lower adsorption tube (4) to release the adsorption on the persimmon.

[0030] The peeled persimmons automatically fall off the suction head (5) below under the action of gravity.

[0031] On the base plate (1) below the mechanism or on the equipment frame, a receiving trough, conveyor belt and other receiving structures can be designed and installed to receive and transfer the peeled persimmons.

[0032] 5. Cyclic operation: After the persimmons in the lower station are fed, the rotating plate (3) can rotate 180 degrees again to transfer the persimmons that have been positioned to the peeling station. At the same time, the empty upper station continues to feed and position the persimmons in the next cycle.

[0033] Appliance model description: Negative pressure pump (6): Small, low-noise vacuum generators or micro vacuum pumps can be selected, such as FESTO VN series or SMC ZH series vacuum generators. They are small in size, fast in response, and suitable for automated equipment.

[0034] First motor (16), second motor (18), and third motor (22): All can be servo motors (such as Panasonic Minas A6 series and Mitsubishi MR-JE series) or stepper motors (such as Leadshine DM series) with good precision and reliability, so as to accurately control the speed and direction.

[0035] Electric actuator (17): Used to drive the movable plate (9) to move closer to or away from the rotating disk (3), and can provide auxiliary support or make way when loading. Small linear electric actuators such as TIMMOTION TJ series can be selected.

[0036] This utility model provides an automated persimmon peeling and positioning mechanism that integrates precise positioning, non-destructive fixing, efficient peeling, and automatic feeding. It effectively overcomes the shortcomings of existing technologies and is very suitable for application in modern persimmon processing production lines. Specifically, this embodiment solves the problem that existing automated persimmon peeling machines require a positioning mechanism to fix the persimmons when peeling them. In order to fix the persimmons and prevent them from slipping away from the peeling blade during peeling, it is usually necessary to insert a rod into the persimmon or clamp the persimmon firmly at both ends. However, these fixing methods either cause the persimmons to break or prevent the end of the persimmon from being peeled smoothly, resulting in significant defects in the usage effect.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
