[0002] In the production of handicrafts, the surface of the handicrafts usually needs to be polished to remove surface defects and make the surface smoother and more even. In the prior art, Chinese utility model patent CN221936394U discloses a metal part vibratory polishing device, including a base and a vibratory basin. A through hole is opened in the center of the top of the base, and a vibratory motor is vertically installed through the center of the base, passing through the through hole. A power cord is provided at one end of the base, and a cover is movably installed on the top of the vibratory basin. The device is characterized by a switch on the front of the base, which is electrically connected to the vibratory motor and the power cord. A vibratory plate is fixedly installed on the top of the vibratory motor, and the top of the vibratory plate is fixedly connected to the bottom of the vibratory basin.

[0003] During the operation of the aforementioned metal part vibration polishing device, the vibration motor of the device drives the vibration plate to vibrate, and the vibration plate drives the vibration basin to vibrate. The kinetic energy generated by the vibration motor drives the abrasive stored in the vibration basin to vibrate with the workpiece, and the abrasive is used to polish the surface of the workpiece.

[0004] However, when using the aforementioned metal vibration polishing device to process wood handicrafts with low density, the wood handicrafts tend to float on the surface of the abrasive during the polishing process, thus reducing the processing efficiency. Summary of the Invention

The input end of the screw conveyor is connected to the bottom of the inner cavity of the supporting shell, and the output end of the screw conveyor is connected to the inner cavity of the top cover. It is used to transport abrasive materials. Several discharge ports are opened on the bottom wall of the inner cavity of the top cover. Any one of the discharge ports penetrates the inner wall of the top cover and communicates with the inner cavity of the supporting shell. The several discharge ports are distributed in a circumferential array around the screw conveyor for conveying abrasive materials.

[0006] Furthermore, the device also includes: a stirring turntable, which is rotatably mounted on the bottom wall of the inner cavity of the bearing housing, and the stirring turntable is fixedly connected to the bottom end of the auger of the screw conveyor.

[0007] Furthermore, the device also includes: a stirring support, which is movably disposed in the inner cavity of the top cover and is connected to the auger of the screw conveyor for stirring the abrasive located in the inner cavity of the top cover.

[0008] Furthermore, this device also includes several switching components, which are respectively disposed on the top cover and connected to several feeding ports to control the opening and closing of the feeding ports.

[0009] Furthermore, the switch assembly includes: an opening and closing plate, a rope winding machine, and a traction rope; The opening and closing plate is set in the discharge port. The head end of the opening and closing plate is hinged to the inner wall of the discharge port. The shape of the opening and closing plate matches the inner cavity of the discharge port and is used to close the discharge port. The rope winding machine is fixedly mounted on the top cover; One end of the traction rope is connected to the execution end of the rope winding machine, and the other end of the traction rope is connected to the tail end of the opening and closing plate, which is used to pull the opening and closing plate to flip upward.

[0010] Furthermore, the device also includes: several guide plates, which are fixedly installed on the side wall of the outer shell of the screw conveyor, and are fixedly connected to the inner wall of the bearing shell. The positions of the guide plates correspond one-to-one with the positions of the discharge ports. Any guide plate is spirally arranged along the circumference of the outer shell of the screw conveyor and toward the bottom end of the outer shell of the screw conveyor. The rotation direction of the guide plate is opposite to the rotation direction of the auger of the screw conveyor.

[0011] Furthermore, the device also includes: a plurality of baffle shafts, which are disposed at the bottom of the inner cavity of the bearing housing. Any baffle shaft is arranged radially along the bearing housing. The plurality of baffle shafts are arranged in a circumferential array around the screw conveyor. The head end of the baffle shaft is rotatably connected to the outer shell of the screw conveyor, and the tail end of the baffle shaft is rotatably connected to the inner wall of the bearing housing.

[0012] Furthermore, the radial cross-sectional shape of the stop shaft is elliptical, and the maximum outer diameter of the tail end of the stop shaft is greater than the maximum outer diameter of the head end of the stop shaft.

[0013] Furthermore, the baffle shaft is spiral-shaped.

[0014] Furthermore, the device also includes a vibration device, the drive end of which is connected to the bearing housing and is used to drive the bearing housing to vibrate.

[0015] The surface polishing and grinding apparatus for craft processing according to an embodiment of the present invention has the following beneficial effects: 1. By adding a screw conveyor and a discharge port, this device continuously covers the wooden handicrafts with circulating abrasive during the polishing process, increasing the contact area between the wooden handicrafts and the abrasive, thereby improving the polishing efficiency of the device. This solves the problem of low processing efficiency in existing vibratory polishing devices when processing low-density workpieces.

[0016] 2. This device is equipped with a screw conveyor, multiple feeding ports, multiple switching components, and multiple baffle shafts. The switching components block the abrasive from flowing back into the inner cavity of the bearing housing through the feeding ports, and gradually transfer the abrasive to the inner cavity of the top cover. During this process, the baffle shafts separate the abrasive from the wooden handicrafts, making it convenient for users to obtain the polished wooden handicrafts.

[0017] 3. This device uses a turntable at the bottom of the inner cavity of the bearing housing to move the abrasive and wooden handicraft stored in the inner cavity of the bearing housing along the circumferential direction of the bearing housing. In addition, this device also uses multiple guide plates in the inner cavity of the bearing housing to guide the abrasive flowing back through the discharge port, so that the abrasive gets an initial velocity opposite to the displacement direction of the wooden handicraft before being covered by the abrasive layer in the inner cavity of the bearing housing. This increases the resistance of the wooden handicraft during the circumferential displacement of the bearing housing, thereby increasing the processing efficiency of this device.

[0026] Furthermore, such as Figure 1 , 4 As shown, the device also includes: a stirring turntable 3, which is rotatably mounted on the bottom wall of the inner cavity of the bearing housing 1, and the stirring turntable 3 is fixedly connected to the bottom end of the auger of the screw conveyor 2.

[0027] Preferred, such as Figure 1 , 4As shown, in this embodiment, the stirring disc 3 includes: a disc body 31 and a plurality of baffle protrusions 32; the disc body 31 is rotatably mounted on the bottom wall of the inner cavity of the bearing housing 1, and the radial cross-sectional shape of the disc body 31 matches the radial cross-sectional shape of the inner cavity of the bearing housing 1, for driving the abrasive stored in the inner cavity of the bearing housing 1 to move circumferentially along the bearing housing 1; a plurality of baffle protrusions 32 are fixedly mounted on the top of the disc body 31, any one baffle protrusion 32 is arranged radially along the disc body 31, and the plurality of baffle protrusions 32 are arranged in a circumferential array around the central axis of the disc body 31, for driving the abrasive carried by the disc body 31 to move circumferentially along the bearing housing 1 with the disc.

[0028] Furthermore, such as Figure 1 As shown, the device also includes: a stirring support 4, which is movably disposed in the inner cavity of the top cover 11. The stirring support 4 is connected to the auger of the screw conveyor 2. During the operation of the screw conveyor 2, the stirring support 4 rotates synchronously with the auger to stir the abrasive located in the inner cavity of the top cover 11, so that the abrasive is evenly distributed in the inner cavity of the top cover 11.

[0029] Furthermore, such as Figure 1 As shown, the device also includes several switch components 5, which are respectively disposed on the top cover 11. The several switch components 5 are respectively connected to several feeding ports and are used to control the opening and closing of the several feeding ports.

[0030] Furthermore, such as Figure 1 , 2 As shown, the switch assembly 5 includes: an opening and closing plate 51, a rope winding machine 52, and a traction rope 53; the opening and closing plate 51 is disposed in the discharge port, the head end of the opening and closing plate 51 is hinged to the inner wall of the discharge port, and the shape of the opening and closing plate 51 matches the inner cavity of the discharge port for closing the discharge port; the rope winding machine 52 is fixedly disposed on the top cover 11; one end of the traction rope 53 is connected to the execution end of the rope winding machine 52, and the other end of the traction rope 53 is connected to the tail end of the opening and closing plate 51 for pulling the opening and closing plate 51 to flip upward.

[0031] Preferably, in this embodiment, the rope winding machine 52 includes: a support bracket, a bobbin, and a drive motor; the support bracket is fixedly mounted on the top cover 11; the bobbin is rotatably mounted on the support bracket, and the bobbin is connected to one end of the traction rope 53 for winding the traction rope 53; the drive motor is fixedly mounted on the support bracket, and the drive end of the drive motor is connected to the bobbin for driving the bobbin to rotate.

[0032] Furthermore, such as Figure 1 , 3As shown, this device also includes: several guide plates 6, which are fixedly installed on the side wall of the outer shell of the screw conveyor 2. The guide plates 6 are fixedly connected to the inner wall of the bearing shell 1. The positions of the guide plates 6 correspond one-to-one with the positions of the discharge ports. Any guide plate 6 is spirally arranged along the circumference of the outer shell of the screw conveyor 2 and toward the bottom end of the outer shell of the screw conveyor 2. The rotation direction of the guide plate 6 is opposite to the rotation direction of the screw conveyor 2. During the process of the abrasive flowing back to the inner cavity of the bearing shell 1 through the discharge port, the abrasive is transmitted through the guide plates 6. This allows the abrasive to obtain an initial velocity opposite to the displacement direction of the wooden handicraft before being covered by the abrasive layer located in the inner cavity of the bearing shell 1. This increases the resistance of the wooden handicraft during the circumferential displacement along the bearing shell 1, thereby increasing the processing efficiency of this device.

[0033] Furthermore, such as Figure 1 As shown, the device also includes: a plurality of baffle shafts 7, which are arranged at the bottom of the inner cavity of the bearing housing 1. Any baffle shaft 7 is arranged radially along the bearing housing 1. The plurality of baffle shafts 7 are arranged in a circular array around the screw conveyor 2. The head end of the baffle shaft 7 is rotatably connected to the outer shell of the screw conveyor 2, and the tail end of the baffle shaft 7 is rotatably connected to the inner wall of the bearing housing 1.

[0034] Furthermore, such as Figure 1 , 5 As shown, the radial cross-sectional shape of the retaining shaft 7 is elliptical, and the maximum outer diameter of the tail end of the retaining shaft 7 is greater than the maximum outer diameter of the head end of the retaining shaft 7.

[0035] Furthermore, such as Figure 1 , 5 As shown, the baffle shaft 7 is spiral-shaped. In this embodiment, the baffle shaft 7 is designed as a spiral with an elliptical radial cross-section so that after the wooden crafts are separated from the abrasive, the stirring disc 3 drives the abrasive to move circumferentially along the bearing housing 1. The wooden crafts carried by the baffle shaft 7 can be vibrated by rotating the baffle shaft 7, thereby shaking off the abrasive adhering to the wooden crafts.

[0036] Furthermore, such as Figure 1 As shown, the device also includes: a vibration device (not shown in the figure), the drive end of which is connected to the bearing housing 1 and is used to drive the bearing housing 1 to vibrate.

[0037] When the equipment is running, the vibration device is activated, driving the bearing housing 1 and the abrasive stored in the inner cavity of the bearing housing 1 to vibrate against the wooden handicrafts, thereby using the abrasive to polish the surface of the wooden handicrafts. At the same time, the screw conveyor 2 is activated, conveying the abrasive located at the bottom of the inner cavity of the bearing housing 1 to the inner cavity of the top cover 11. The abrasive located in the inner cavity of the top cover 11 then flows back to the inner cavity of the bearing housing 1 through multiple discharge ports, covering and submerging the wooden handicrafts floating on the surface of the abrasive in the inner cavity of the bearing housing 1, thereby increasing the contact area between the surface of the wooden handicrafts and the abrasive, and improving the processing efficiency of the handicrafts by the device. During the operation of the screw conveyor 2, the auger of the screw conveyor 2 drives the stirring disc 3 to rotate synchronously. The stirring disc 3 drives the abrasive located in the inner cavity of the bearing housing 1 and the wooden handicrafts to move circumferentially along the bearing housing 1, further improving the working efficiency of the device on the wooden handicrafts, while ensuring that the abrasive flowing back to the inner cavity of the bearing housing 1 through the discharge ports can evenly cover the surface of the abrasive located in the inner cavity of the bearing housing 1.

[0038] When the user needs to remove the handicrafts inside the housing 1, the user controls the rope winding machine 52 of several switch components 5 to start. The rope winding machine 52 winds up the traction rope 53, causing the opening and closing plate 51 to flip upward, thereby closing multiple discharge ports. As the screw conveyor 2 continues to run, the screw conveyor 2 gradually transfers the abrasive in the inner cavity of the housing 1 to the inner cavity of the top cover 11. As the surface position of the abrasive in the inner cavity of the housing 1 drops below the position of the baffle shaft 7, the handicrafts are blocked by the baffle shaft 7, causing the baffle shaft 7 to separate from the abrasive. During the operation of the screw conveyor 2, under the power output of the stirring turntable 3, the abrasive drives the baffle shaft 7 to rotate. During the rotation of the baffle shaft 7, the wooden handicrafts it carries vibrate, causing the abrasive adhering to the wooden handicrafts to fall off.

[0039] Above, refer to Figures 1-5 A surface polishing and grinding apparatus for craft processing according to an embodiment of the present invention is described, which has the following beneficial effects: 1. By adding a screw conveyor 2 and a discharge port, this device can continuously cover the wooden handicrafts with abrasive through the circulation of abrasive during the process of grinding and polishing wooden handicrafts. This increases the contact area between the wooden handicrafts and the abrasive, thereby improving the grinding and polishing efficiency of the device. This solves the problem of low processing efficiency in the processing of low-density workpieces by existing vibratory polishing devices.

[0040] 2. This device is equipped with a screw conveyor 2, multiple feeding ports, multiple switch components 5, and multiple baffle shafts 7. The switch components 5 block the abrasive from flowing back into the inner cavity of the bearing housing 1 through the feeding ports, and gradually transfer the abrasive to the inner cavity of the top cover 11. During this process, the baffle shafts 7 separate the abrasive from the wooden handicrafts, so that users can easily obtain the polished wooden handicrafts.

[0041] 3. This device uses a turntable at the bottom of the inner cavity of the bearing housing 1 to drive the abrasive and wooden handicraft stored in the inner cavity of the bearing housing 1 to move along the circumferential direction of the bearing housing 1. In addition, this device also uses multiple guide plates 6 in the inner cavity of the bearing housing 1 to guide the abrasive flowing back through the feed port, so that the abrasive gets an initial velocity opposite to the displacement direction of the wooden handicraft before being covered by the abrasive layer in the inner cavity of the bearing housing 1, thereby increasing the resistance of the wooden handicraft during the circumferential displacement of the bearing housing 1, and thus increasing the processing efficiency of this device.
