[0016] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0017] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] To address the shortcomings of existing shell material positioning methods, such as insufficient accuracy, high cost, or limited applicability, this invention provides a rounding device for shell craft production. The device includes a vertically movable mounting cylinder with a contact pad at its bottom. A ball bearing mechanism is elastically installed inside the cylinder, eccentrically positioned relative to the center of the turntable. A positioning auxiliary component includes a limiting element for restricting the side of the shell craft. When the shell craft is positioned on the turntable by the ball bearing mechanism and rotates with the turntable, the action of the ball bearings and the limiting element causes the shell craft to rotate around the ball bearing positioning point, shifting towards the turntable center. This confines the shell craft within the target area defined by the limiting element, preventing excessive deviation from the turntable center and improving the positioning accuracy of the shell craft material on the turntable, thus increasing production efficiency.

[0021] Specifically, such as Figure 1 As shown, the rounding device for producing seashell handicrafts in this embodiment includes a machine base 100, and a turntable 110, a polishing component 120, an upper pressing component 130 and a positioning auxiliary component 140 disposed on the machine base 100. The upper pressing component 130 is used to press and fix the seashell handicraft on the turntable 110, and the contact part with the target seashell handicraft is rotatable so as to follow the rotation of the turntable 110.

[0022] Please refer to further details. Figure 2 The turntable 110 is equipped with a first contact pad 111 to increase friction and ensure the rotational drive capability for the seashell crafts. Two sets of polishing components 120 are provided and symmetrically arranged on opposite sides of the turntable 110, allowing for simultaneous polishing and improving polishing efficiency. The two sets of polishing components 120 move synchronously along the radial direction of the turntable 120 to ensure that the polishing radius is the same.

[0023] The grinding assembly 120 includes a grinding head 121, a first drive motor 122, a sliding frame 123, and an electric guide rail 124. The sliding frame 123 is slidably mounted on the electric guide rail 124, the first drive motor 122 is fixedly mounted on the sliding frame 123, and the grinding head 121 is vertically fixed on the output shaft of the first drive motor 122.

[0024] A positioning auxiliary component 140 is disposed on one side to limit the side of the seashell craft, such as... Figure 4 As shown, the limiting member 141 is preferably a roller shaft, which can prevent frictional damage to the edge of the shell craft 101.

[0025] The upper clamping assembly 130 is positioned above the turntable 110, such as... Figure 3 and Figure 4 As shown, the upper clamping assembly 130 includes a vertically movable mounting cylinder 131. A second contact pad 1311 is provided at the bottom of the mounting cylinder 131. A ball bearing mechanism 132 is elastically provided inside the mounting cylinder 131. The second contact pad 1311 and the ball bearing mechanism 132 are mounted on an inner bushing 1312. The inner bushing 1312 is rotatably connected to the mounting cylinder 131. As the mounting cylinder 131 moves toward the turntable 110, the balls of the ball bearing mechanism 132 and the second contact pad 1311 can contact the shell craft 101 successively. The ball bearing mechanism 132 is eccentrically positioned relative to the center of the turntable 110 and is located in the area between the center of the turntable and the limiting member.

[0026] In use, the shell craft 101 is placed on the turntable 110, at least below the ball bearing mechanism 132. The upper clamping assembly 130 is driven to move down to the first position, so that the balls of the ball bearing mechanism 132 press against the shell craft 101. The clamping force is determined by the corresponding spring to ensure both clamping reliability and the mobility between the balls of the ball bearing mechanism 132 and the shell craft 101. Then, the turntable 110 is driven. When the maximum deviation distance between the edge of the shell craft 101 and the center of the turntable 120 is greater than the distance between the limiting member 141 and the center of the turntable 120, the excess part is restricted by the limiting member 141 during rotation. The positioning point of the ball bearing mechanism 132 can continue to rotate with the turntable 120. Relative to the positioning point of the ball bearing mechanism 132, the shell craft 101 can rotate in the opposite direction, so that the maximum edge point of the shell craft 101 can deviate towards the center of the turntable 120 until it falls completely into the target area defined by the limiting member 141, thus completing the loading and positioning process. In the material loading and positioning process, the shell craft 101 needs to be able to slide on the first contact pad 111 of the turntable 110. Correspondingly, the coefficient of friction of the first contact pad 111 and the clamping force of the ball mechanism 132 need to be designed according to the actual situation. This application does not make any special limitations on the specific parameters.

[0027] Then, the upper pressing component 130 is driven to move downward until the second contact pad 1311 presses and fixes the shell craft 101 on the turntable 110, preventing the shell craft 101 from sliding on the turntable 110.

[0028] Since the grinding component 120 has a limited range of motion, there is a minimum grinding radius. If the minimum radius of the target seashell craft 101 relative to the center of the turntable 100 after positioning is less than the minimum grinding radius, a round finished product cannot be obtained. To avoid resource waste, this embodiment also includes a detection module, which is used to detect the relationship between the minimum radius of the seashell craft 101 and the minimum grinding radius of the grinding component after the seashell craft 101 has completed the feeding and positioning process, so as to determine whether the seashell craft meets the condition for roundness. If the condition for roundness is not met, grinding will not be carried out, and other seashell craft materials will be replaced to avoid the waste of resources due to ineffective grinding.

[0029] Specifically, such as Figure 4 and Figure 5 As shown, the detection module includes a movable block 142 and a movable frame 143. The movable block 142 is slidably disposed in the machine base 100. The limiting member 141 is a roller shaft, which is mounted on the limiting member mounting frame 1411. The limiting member mounting frame 1411 is elastically connected to the movable block 142. The movement directions of both the movable block 142 and the limiting member 141 point towards the center of the turntable 110. A first contact electrode 145 is fixedly disposed on the side of the movable block 142 away from the turntable 110. The movable frame 142 is disposed on the side of the movable block 142 away from the turntable 110. The movable frame 143 is elastically connected to the movable block 142. A second contact electrode (not shown in the figure) is disposed on the movable frame 143.

[0030] The first contact electrode 145 and the second contact electrode are set in the detection circuit. The detection circuit is connected to the power supply 161 and the indicator light 162. When the first contact electrode 145 and the second contact electrode are connected, the detection circuit is turned on and the indicator light 162 lights up. The detection module can also be equipped with a microcontroller connected to the detection circuit. The microcontroller can monitor the on / off state of the detection circuit. It can also effectively detect and record cases where the time interval between on / off transitions is small, avoiding the problem of missed detection due to the short circuit time and the lack of effective perception by the workers.

[0031] The first contact electrode 145 and the second contact electrode can also be designed as sliding rheostats. The microcontroller detects the resistance in the detection circuit and can obtain the current radius of the shell craft 101 in real time.

[0032] The movable block 142 has an I-shaped structure and its range of motion is limited at both ends. During the feeding and positioning process, one end of the movable block 142 rests on the machine 100, and the limiting component 141 is fixed relative to the movable block 142 by a locking mechanism, so that the movable block 142 and the limiting component 141 are in a fixed state in the direction away from the turntable 110, ensuring the reliability of the limit.

[0033] In this embodiment, the step of detecting the relationship between the minimum radius of the shell craft and the minimum grinding radius of the grinding component to determine whether the shell craft meets the condition for roundness includes: setting the movable block 142 and the limiting member 141 to a movable state, driving the movable frame 143 to move to the limit position on the turntable 110; driving the turntable 110 to rotate the shell craft 101 at least one revolution, and determining whether the shell craft 101 meets the condition for roundness based on the connection state of the detection circuit; wherein, when the detection circuit alternates between on and off, it is determined that the shell craft does not meet the condition for roundness, and when the detection circuit is in a normally connected state, it is determined that the shell craft meets the condition for roundness.

[0034] When the movable frame 143 moves to its limit position on the turntable 110, if the current radius of the shell craft facing the limiting member 141 is equal to the minimum polishing radius, the first contact electrode 145 and the second contact electrode should be in just-contact. When the current radius is less than the minimum polishing radius, the first contact electrode 145 and the second contact electrode separate, and the detection circuit is disconnected. When the current radius is greater than the minimum polishing radius, the first contact electrode 145 and the second contact electrode make electrical contact, and the detection circuit is connected. The structure of the first contact electrode 145 and the second contact electrode can be specifically selected according to actual needs, as long as the above-mentioned boundary contact conditions are met.

[0035] To achieve locking and unlocking control of the limiting member 141, in this embodiment, the detection module further includes a locking member 1421 and an unlocking member 1431, forming a locking mechanism. The locking member 1421 is disposed between the movable block 142 and the limiting member mounting bracket 1411 of the limiting member 141, and is used to restrict the movement of the limiting member 141 toward the movable block 142. The unlocking member 1431 is disposed on the movable bracket 143, and is used to drive the locking member 1421 to move away from the movable block 142 and the limiting member 141 when the movable bracket 143 moves to the limit position on the turntable 110, thereby releasing the restriction on the limiting member 141.

[0036] As a specific example, in this embodiment, the locking member 1421 and the unlocking member 1431 are matched by an inclined surface. The locking member 1421 includes a limiting part and an unlocking part. The limiting part is horizontally locked between the movable block 142 and the limiting member mounting bracket 1411 and can move vertically. The unlocking part is matched with the unlocking member 1431 by an inclined surface. When the unlocking member 1431 moves with the movable bracket 143 and acts on the unlocking part, it can push the unlocking part upward, thereby causing the limiting part to move away from the movable block 142 and the limiting member mounting bracket 1411, thereby releasing the limiting.

[0037] Two sets of springs are arranged between the limiting component mounting bracket 1411, the movable block 142 and the movable frame 143, which can increase the movable range of the movable limiting component 141, increase the size adaptability of the shell craft 101, and thus increase the applicability of the rounding device.

[0038] To facilitate the driving of the upper clamping assembly 130, in this embodiment, the upper clamping assembly 130 is connected to the horizontal driver 133 via a transmission frame 134, so that the horizontal driving force of the horizontal driver 133 can be converted into a vertical driving force through the transmission frame 134. The C-shaped structure of the machine base 100 can be used to set the transmission frame 134 in the space behind the mounting cylinder 131, thereby reducing the occupation of the vertical space by the driving structure and improving the space utilization of the machine base 100.

[0039] The movable frame 143 is also drive-connected to the horizontal drive 133 so that when the upper clamping assembly 130 clamps and fixes the shell craft, the movable frame 143 is driven to move to the limit position synchronously.

[0040] Specifically, the movable frame 143 includes a guide rail 1432, and a transmission frame 134 is slidably connected to the guide rail 1432. The stroke of the guide rail 1432 is less than the stroke of the transmission frame 134. During the loading and positioning process, the stroke of the transmission frame 134 is less than or equal to the stroke of the guide rail 1432 to keep the movable frame 143 positioned in its initial position, without any thrust on the movable block 142, ensuring that the movable block 142 and the limiting member 141 are fixed in a direction away from the turntable 110. When the transmission frame 134 moves from the first position to its limit position, the transmission frame 134 can move to the limit position of the guide rail 1432 and drive the movable frame 143 to continue moving to its limit position. This allows the position of the limiting member 141 to be unlocked via the movable frame 143, enabling the detection of roundness conditions.

[0041] The upper clamping component of the rounding device for seashell craft production provided by this invention includes a vertically movable mounting cylinder. A contact pad is provided at the bottom of the mounting cylinder, and a ball bearing mechanism is elastically arranged inside the mounting cylinder. The ball bearing mechanism is eccentrically positioned relative to the center of the turntable. The positioning auxiliary component includes a limiting member for limiting the side of the seashell craft. When the seashell craft is positioned on the turntable by the ball bearing mechanism and rotates with the turntable, the action of the ball bearing and the limiting member allows the seashell craft to rotate around the ball bearing positioning point and shift towards the center of the turntable, thereby limiting it within the target area defined by the limiting member. This prevents it from deviating too much from one side relative to the center of the turntable, improves the positioning accuracy of the seashell craft raw material on the turntable, and increases production efficiency.
