Description

Technical Field

[0001] This application relates to the field of persimmon peeling knife devices, and particularly to a persimmon peeling knife device. Background Technology

[0002] Persimmons, a popular fruit, require peeling before being processed into dried persimmons, preserved persimmons, and other products. Currently, in addition to traditional manual peeling, automated peeling equipment has emerged on the market.

[0003] Existing automated peeling equipment typically uses fixed rotary blades or simple linear feed blades. However, persimmons are not standard spheres or cylinders; they usually have a complex curved surface, resembling an oblate spheroid with relatively flat top and bottom ends and a bulging center. When using blades with a fixed trajectory for peeling, it is difficult to completely conform to the natural contours of the persimmon, resulting in incomplete peeling, leaving peel residue, or cutting too deep into the flesh, causing waste of raw materials.

[0004] To address these issues, some improvements have attempted to introduce contour-following tool systems. For example, two independent drive units are used to control the tool's lifting and oscillating movements, respectively. Through complex control system programming, the tool's trajectory is made to approximate the shape of a persimmon as closely as possible. However, this approach has significant drawbacks: First, its mechanical structure is complex, requiring at least two drive motors and corresponding transmission systems, leading to high manufacturing and maintenance costs. Second, it places high demands on the control system, requiring precise coordination of the two motors, which is difficult to debug and carries the risk of synchronization errors, affecting the stability of the peeling quality. Utility Model Content

[0005] The purpose of this application is to provide a peeling knife device that is simpler in structure, more reliable, lower in cost, and can accurately adapt to changes in the shape of persimmons.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A persimmon peeling tool device includes: a mounting plate;

[0008] The drive motor has one output shaft;

[0009] The transmission mechanism includes a meshing gear and a fixed rack, wherein the gear is fixedly sleeved on the output shaft of the drive motor, and the fixed rack is fixedly mounted on the mounting plate;

[0010] The lifting seat is fixedly connected to the body of the drive motor;

[0011] A linear guide mechanism, connected between the lifting seat and the mounting plate, is used to guide the lifting seat to move up and down along a linear trajectory;

[0012] A swing arm is fixedly mounted on the output shaft of the drive motor via a connecting seat, so that the rotation of the output shaft can directly drive the swing arm to swing around the axis of the output shaft.

[0013] A cutting tool assembly is installed at the free end of the swing arm. The cutting tool assembly includes a mounting bracket, a cutting blade, and a spring. The cutting blade is installed on the mounting bracket, and one end of the spring is connected to the swing arm and the other end is connected to the fixed base.

[0014] A reset device is installed on the swing arm to drive the cutter assembly to reset, so that the blade is away from the persimmon peel.

[0015] Furthermore, the linear guiding mechanism is a linear guide pair or a guide rod and sleeve mechanism.

[0016] Furthermore, the reset device is a cylinder.

[0017] Furthermore, the mounting bracket is provided with an elongated hole, and the blade is mounted on the mounting bracket by a bolt passing through the elongated hole. The peeling thickness is adjusted by adjusting the position of the bolt in the elongated hole.

[0018] Furthermore, a buffer is also included, disposed on the mounting plate, for cushioning the end of the descent stroke of the lifting seat.

[0019] Furthermore, it also includes a position sensor for detecting the position of the gear or output shaft.

[0020] The beneficial effects of this application are:

[0021] This application utilizes a clever mechanical structure to simultaneously decompose the single rotational motion of the drive motor into a composite motion of two dimensions: the lifting and oscillating motion of the cutter. The motor's output shaft directly drives the swing arm and cutter to oscillate, while simultaneously, through the meshing of gears with a fixed rack, it propels the entire drive unit to achieve precise linear lifting and lowering. This mechanism of a single power source driving two degrees of freedom synchronous motion fundamentally simplifies the overall structure of the device, significantly reducing manufacturing costs and control complexity. It also effectively avoids errors that may arise from the coordinated motion of multiple systems, thus perfectly conforming to the irregular shape of the persimmon and achieving efficient and high-quality peeling, while greatly improving the reliability and stability of the equipment operation.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

In particular, the understanding of the term "upper" following a noun in the claims should be understood as meaning that the entire inner and outer surfaces of the structure referred to by the noun conform to the definition of "upper."

[0034] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structures, features, and effects provided in this application.

[0035] like Figures 1 to 5As shown, a persimmon Q peeling knife device includes: a mounting plate 1; a drive motor 2 with an output shaft; a transmission mechanism 3 including a meshing gear 31 and a fixed rack 32, the gear 31 being fixedly sleeved on the output shaft of the drive motor 2, and the fixed rack 32 being fixedly mounted on the mounting plate 1; a lifting seat 4, fixedly connected to the body of the drive motor 2; a linear guide mechanism 5, connected between the lifting seat 4 and the mounting plate 1, for guiding the lifting seat 4 to rise and fall along a linear trajectory; a swing arm 6 fixedly mounted on the output shaft of the drive motor 2 via a connecting seat 9. The connecting seat 9 provides a stable and reliable connection interface, ensuring that the swing arm 6 can accurately follow the swing of the motor shaft, so that the rotation of the output shaft can directly drive the swing arm 6 to swing around the axis of the output shaft; a knife assembly 7, mounted on the free end of the swing arm 6, including a mounting bracket 71, a blade 72, and a spring 73; and a reset device 8, mounted on the swing arm 6, for driving the knife assembly 7 to move, so that the blade 72 moves away from the outer skin of the persimmon Q.

[0036] In one embodiment, the linear guide mechanism 5 is a linear guide pair or a guide rod and sleeve mechanism. The linear guide pair or guide rod and sleeve mechanism provides two mature and high-precision guiding options, ensuring smooth and wobbly lifting movements.

[0037] In one embodiment, the reset device 8 is a cylinder.

[0038] In one embodiment, the mounting bracket 71 is provided with an elongated hole 711, and the blade 72 is mounted on the mounting bracket 71 by a bolt passing through the elongated hole 711. The peeling thickness is adjusted by adjusting the position of the bolt in the elongated hole 711.

[0039] In one embodiment, a buffer 10 is also included, disposed on the mounting plate 1, for cushioning the end of the descent stroke of the lifting seat.

[0040] In one embodiment, a position sensor 11 is also included for detecting the position of the gear 31 or the output shaft.

[0041] The working principle of this device is as follows: through the single rotational motion of a drive motor 2, the gear 31-rack mechanism and the output shaft are directly driven to cleverly and synchronously synthesize the two-dimensional composite motion of the cutting tool's lifting and swinging, thereby automatically conforming to the shape of the persimmon Q and completing precise peeling.

[0042] Its specific working process can be broken down into the following steps:

[0043] Step 1: Initial Positioning and Feeding

[0044] The persimmon Q to be peeled is driven by an additional rotating device (the structure is not shown in the figure but is disclosed in CN120531149A) and begins to rotate at a constant speed. The specific rotating device is inserted into the persimmon from the bottom up and rises to the position corresponding to the blade. The rotating device drives the persimmon to rotate, and the persimmon is peeled by the device working in conjunction with the blade.

[0045] The drive motor and transmission mechanism synchronously propel the entire cutter assembly 7 radially along the swing arm 6, causing the blade 72 to contact and slightly press against the outer skin at the top of the persimmon Q. Simultaneously, under the action of a spring, continuous and variable radial pressure is provided to ensure the blade always smoothly conforms to and follows the irregular curves of the persimmon's shape. When encountering a protrusion, the spring compresses, causing the blade to retract; when passing a depression, the spring extends, causing the blade to follow. Thus, based on the macroscopic motion trajectory determined by the rigid mechanism, microscopic adaptive contouring is achieved, ultimately ensuring clean peeling while effectively preventing damage to the fruit or the cutter.

[0046] Step 2: Simultaneous contour peeling

[0047] Drive motor 2 starts, and its output shaft begins to rotate in a preset direction and speed.

[0048] The output shaft directly drives the swing arm 6 and the tool assembly 7 at its end to swing together. This enables the cutting tool 72 to move along the contour arc of the persimmon Q.

[0049] At the same time, the gear 31, which is fixedly mounted on the output shaft, also rotates. Since the rack that meshes with the gear 31 is fixed on the mounting plate 1, the gear 31 cannot roll in place. The reaction force generated by its rotation will push the entire body of the drive motor 2, together with the lifting seat 4, the swing arm 6 and the tool assembly 7 fixed together, as a whole, to rise and fall along the linear guide mechanism 5.

[0050] The aforementioned swinging and lifting movements are synchronously driven by the same rotating shaft. By rationally designing the diameter of gear 31, the mounting position of the rack, and the speed of the motor, the movement trajectory of the blade tip can be made to perfectly match the outer contour of the persimmon Q (from top to bottom). With the cooperation of the rotation of the persimmon Q itself, the blade 72 can achieve a spiral contour-following peeling motion.

[0051] Step 3: Process Regulation and Protection

[0052] By loosening the bolts and adjusting the position of the blade 72 in the elongated hole 711 of the mounting bracket 71, the initial cutting depth of the blade 72 relative to the surface of the persimmon Q can be changed, thereby achieving precise control of the peeling thickness.

[0053] The buffer 10 acts as a buffer at the end of the stroke to prevent the device from impacting hard. The position sensor 11 indirectly monitors the real-time position of the tool by detecting the position of the gear 31, ensuring the accuracy of the movement and allowing the stroke range to be set.

[0054] Step 4: Reset

[0055] Once peeling is complete, the reset device first drives the blade away from the persimmon surface, while simultaneously driving motor 2 to reverse, causing the entire device to rise and swing back to its initial position. The reset device 8 then retracts the blade 72, preparing for the next work cycle.

[0056] The embodiments described above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
