Description

Technical Field

[0001] This utility model relates to the technical field of fruit processing machinery and equipment, specifically to a multi-station rotary cutter device. Background Technology

[0002] In the fruit processing industry, including canned fruit and juice production, efficient and high-quality fruit peeling is a crucial step. For citrus fruits like oranges, traditional manual peeling methods are extremely inefficient, resulting in uneven peel thickness and potential damage to the fruit. Existing automated peeling equipment often suffers from the following drawbacks in its blade drive mechanism: 1) It uses multiple independent motors to drive each blade, leading to high costs, complex control, and difficulty in ensuring synchronized movement of all blades; 2) The drive structure is complex, resulting in low transmission efficiency and inconvenient maintenance; 3) The blades lack a buffer mechanism, making them prone to jamming or cutting the fruit when encountering uneven surfaces; 4) It cannot achieve unified cutting and retraction control for all blades, making operation cumbersome. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned technical problems, the purpose of this utility model is to propose a multi-station rotating tool device with a compact structure, high transmission efficiency, and the ability to synchronously drive multiple tool heads and perform precise control.

[0004] The technical solution adopted is as follows:

[0005] A multi-station rotary tool device, comprising:

[0006] A drive assembly, comprising a power source and a main drive shaft driven by the power source;

[0007] Multiple peeling units are arranged side by side along the axial direction of the main drive shaft;

[0008] Each of the peeling units includes:

[0009] The worm gear is fixedly mounted on the main drive shaft;

[0010] A worm gear, which meshes with the worm;

[0011] The tool holder is connected to the worm gear, so that the rotational motion of the worm gear can be converted into the arc-shaped oscillation of the tool holder;

[0012] A blade, mounted on the blade holder, is used to peel the fruit.

[0013] Furthermore, the tool holder is connected to the worm gear via an elastic element.

[0014] Furthermore, the multi-station rotary tool device also includes a swing control mechanism, which is located next to the tool holder and is used to control the swing of the tool holder.

[0015] Furthermore, the swing control mechanism includes:

[0016] A slide bar, which is rotatably mounted on the frame;

[0017] Multiple support plates are fixedly installed on the slide rod, each corresponding to a multiple peeling unit; each support plate has a hook groove that hooks onto the blade holder of the corresponding peeling unit.

[0018] A drive mechanism is provided, in which the slide bar is connected and the drive mechanism drives the slide bar to rotate.

[0019] Furthermore, the power source is a stepper motor.

[0020] Furthermore, the main drive shaft is supported on the frame by a bearing housing.

[0021] The beneficial effects of this utility model are as follows:

[0022] Firstly, a single power source drives a main drive shaft, which in turn drives all the blades to work synchronously through multiple sets of worm gear mechanisms arranged in parallel on the shaft. This ensures the consistency of peeling actions at all workstations, resulting in a compact structure, high transmission efficiency, and reduced manufacturing and maintenance costs.

[0023] Secondly, the worm gear transmission is smooth and can accurately convert the rotational motion of the spindle into the planetary arc swing of the tool holder, which, in conjunction with the rotating fruit, forms a cutting trajectory for the orange, resulting in thorough and uniform peeling.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] See Figures 1-3 The multi-station rotary cutting device shown includes a drive assembly and multiple peeling units arranged side by side.

[0033] The drive assembly consists of a power source 14 and a main drive shaft 15. In this embodiment, the power source 14 is preferably a stepper motor, which is connected to one end of the main drive shaft 15 via a coupling. The main drive shaft 15 is supported on the frame by two bearing seats 23 to ensure smooth rotation.

[0034] There are multiple peeling units ( Figure 1-3 (Illustrated diagram of 10 units). Each peeling unit includes a worm gear 16, a worm wheel 17, a blade holder 18, and a blade 4. The worm gear 16 is fixedly mounted on the main drive shaft 15 via a key connection or other means and rotates with the main shaft. The worm wheel 17 meshes with the worm gear 16. The blade holder 18 is connected to the worm wheel 17 via a rotating shaft. When the main drive shaft 15 rotates, it drives all the worm gears 16 to rotate synchronously, which in turn drives their corresponding worm wheels 17 to rotate. The rotational motion of the worm wheel 17 is converted into the arc-shaped oscillation of the blade holder 18 via the rotating shaft. The blade 4 is fastened to the front end of the blade holder 18 and is used to perform the peeling operation on the fruit.

[0035] An elastic element (such as a compression spring) is provided between the blade holder 18 and the shaft that drives it. This structure allows the blade holder 18 and the blade 4 to have a certain elastic buffer space in the radial direction, so that they can adapt to the shape of the fruit during the peeling process and play an overload protection role.

[0036] In addition, this multi-station rotary cutting device also includes a swing control mechanism. This mechanism consists of a slide rod 19, multiple support plates 20 fixed on the slide rod 19, and a drive mechanism (such as a small cylinder or motor). Each support plate 20 corresponds to a peeling unit, and each support plate 20 has a groove 21 machined at its end, which can hook the tail of the corresponding tool holder 18. When it is necessary to uniformly control the cutting depth of all blades 4 or to simultaneously retract all blades 4 from the working position, the drive mechanism drives the slide rod 19 to rotate a certain angle. The slide rod 19 drives all support plates 20 to rotate synchronously. The support plates 20 pull all tool holders 18 through the groove 21 at their front ends, causing them to swing synchronously, thereby achieving centralized and synchronous control of the position of all blades 4.

[0037] The working process of this multi-station rotary tool device is as follows:

[0038] When the stepper motor 14 operates, it drives the main drive shaft 15 to rotate, causing all the worm gears 16 fixed to it to rotate synchronously, and driving the worm wheel 17 meshing with it to rotate, thereby causing all the tool holders 18 and the blades 4 to perform synchronized planetary arc-shaped oscillations (see...). Figure 4 The swing trajectory 22 shown peels the fruit (e.g., oranges 60) at their respective workstations. All blades can be adjusted or retracted uniformly via the swing control mechanism. Elastic elements ensure flexibility and adaptability during the cutting process.

[0039] During the above-mentioned work process,

[0040] Firstly, a single power source drives a main drive shaft, which in turn drives all the blades synchronously through multiple sets of worm gear mechanisms arranged in parallel on the shaft. This ensures the consistency of peeling actions at all stations, resulting in a compact structure, high transmission efficiency, and reduced manufacturing and maintenance costs. Moreover, the drive shaft control offers higher precision and better synchronization compared to belt control.

[0041] Secondly, the worm gear transmission is smooth and can accurately convert the rotational motion of the spindle into the planetary arc swing of the tool holder, which, in conjunction with the rotating fruit, forms a cutting trajectory for the orange, resulting in thorough and uniform peeling.

[0042] Thirdly, the blade holder and worm gear are connected by an elastic mechanism, giving the blade a certain radial buffering capacity. When encountering irregular fruit surfaces or changes in hardness, it can adaptively make fine adjustments, improving the reliability of the device.

[0043] Fourthly, through a unique swing control mechanism, the swing range of all blade holders can be uniformly controlled by a single drive mechanism. Specifically, the support plate is controlled by rotating the slide rod, and the blade holder is supported by the support plate. When the blade holder swings, the blade does not touch the fruit. When the support plate does not support the blade holder, the blade peels. This achieves centralized and precise control of multi-station blades, with a high degree of automation and simple operation.

[0044] Moreover, using a rotating blade holder (planetary arc swing) to peel oranges with a regular peeler results in a uniform peel width and a smoother peel, which significantly improves the utilization rate of oranges. In addition, regular peelers are cheaper and easier to maintain later.

[0045] Fifthly, it adopts stepper motor control, which can adjust the speed of the blade holder according to the shape of the fruit, so as to achieve more precise peeling.

[0046] In addition, oranges are softer than other fruits and have a higher degree of roundness when cut. Therefore, the movement trajectory of the peeler significantly affects the quality of orange peeling. Experiments showed that using a regular peeler with a rotating motion to simulate manual peeling yielded the best results. Furthermore, the use of readily available models of peelers greatly reduces subsequent maintenance costs. Experiments also revealed that with more than six workstations, belt-driven systems could not achieve the required synchronization between the workstations.

[0047] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
