Description

Technical Field

[0001] The utility model patent relates to the technical field of bamboo chopstick processing, specifically a bamboo chopstick surface polishing device used for bamboo chopstick processing. Background Art

[0002] Bamboo chopsticks are long, thin sticks used to pick up food or other objects between the fingers. They are often used as tableware. They are made of materials such as bamboo, wood, ivory, bone, and metal, and come in various shapes, from square to round. After the bamboo tube is split and ground into the shape of chopsticks, the surface of the chopsticks needs to be polished to remove burrs, otherwise the burrs may pierce the skin during use.

[0003] Many existing polishing devices are such as the patent application number CN202222185549.5, which discloses a sharpening and polishing device for bamboo chopsticks. The device includes a main body of the bamboo chopstick sharpening and polishing device, a processing table is provided on the main body of the bamboo chopstick sharpening and polishing device, and linear moving mechanisms are symmetrically installed on both sides of the upper end of the processing table, movable plates are movably provided on the linear moving mechanisms, and driving motors are respectively installed on the movable plates, and blunt grinding wheels and pointed grinding wheels are respectively installed on the driving motors, and the positions of the blunt grinding wheels and pointed grinding wheels correspond to each other, a positioning outer ring is also provided above the processing table, a polishing wheel is engaged with the inner side of the positioning outer ring, and the lower ends of the polishing wheel and the positioning outer ring are provided with discharge ports, a driving frame is provided on the inner side of the polishing wheel, and a limiting ring is engaged with the outer side of the driving frame.

[0004] The sharpening and polishing device for processing bamboo chopsticks can not only sharpen the bamboo chopsticks, but also polish the entire bamboo chopsticks simultaneously, thereby optimizing the processing flow of bamboo chopsticks and making the processing of bamboo chopsticks more efficient. However, this sharpening and polishing device for processing bamboo chopsticks and most of the polishing equipment currently on the market have the following defects: the sharpening and polishing device for processing bamboo chopsticks can only grind around the circumference of the bamboo chopsticks, but cannot grind along the length direction of the bamboo chopsticks. The burrs are often close to the surface of the bamboo chopsticks. If the bamboo chopsticks are not rubbed back and forth along the length direction, the burrs cannot be lifted and ground off, resulting in insufficient grinding and polishing of the surface of the bamboo chopsticks. Utility Model Content

[0005] The utility model is intended to provide a bamboo chopstick surface polishing device for processing bamboo chopsticks, which is mainly used to solve the technical problem that the existing bamboo chopstick polishing device can only grind around the circumference of the bamboo chopstick and cannot grind along the length direction of the bamboo chopstick. The burrs are often close to the surface of the bamboo chopsticks. If the bamboo chopsticks are not rubbed back and forth along the length direction, the burrs cannot be lifted and ground off, resulting in insufficient grinding and polishing of the bamboo chopstick surface.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A bamboo chopstick surface polishing device for processing bamboo chopsticks includes a shell, a cylindrical channel is opened inside the shell, and cover plates are arranged outside the shell and at both ends of the channel for closing the two ends of the channel. The inner wall of the channel is roughened, and a shaking device for shaking the shell in multiple directions is arranged at the bottom of the shell.

[0008] The beneficial effects of this program are as follows:

[0009] The bamboo chopsticks formed by grinding are poured into the channel in the shell, the covers at both ends of the channel are closed, and the shaking device is started. The shaking device drives the shell to shake, and there are multiple shaking directions, so that there is a height difference at both ends of the channel during the shaking process, so that the bamboo chopsticks can slide back and forth along the length direction of the channel in the channel, and are polished back and forth along the length direction of the bamboo chopsticks, thereby promoting the removal of burrs on the bamboo chopsticks; because there are multiple shaking directions, the bamboo chopsticks can also roll along the cylindrical inner wall of the channel during the sliding process. On the one hand, the bamboo chopsticks rub against the inner wall of the channel and rub against each other, so that the bamboo chopsticks are polished circumferentially. On the other hand, the stacked bamboo chopsticks roll along the inner wall. Because the bamboo chopsticks stacked on the upper layer can exchange positions with the bamboo chopsticks on the bottom layer that are attached to the inner wall of the channel during repeated rolling, all bamboo chopsticks have the opportunity to rub against the inner wall of the channel, so that all bamboo chopsticks poured into the channel are polished more fully. In summary, this solution solves the technical problem that the existing bamboo chopstick polishing device can only polish around the circumference of the bamboo chopstick but cannot polish along the length direction of the bamboo chopstick by pouring the bamboo chopsticks into the channel for multi-directional friction. The burrs are often close to the surface of the bamboo chopsticks. If the bamboo chopsticks are not rubbed back and forth along the length direction, the burrs cannot be lifted and ground off, resulting in insufficient polishing of the bamboo chopstick surface.

[0010] Preferably, the cover plate has a semi-circular groove with a roughened surface on the side facing the channel. In this embodiment, the cover plate blocks both sides of the channel. When the housing is shaken, the bamboo chopsticks are driven to slide in the channel. When the bamboo chopsticks slide to the end of the channel, they can slide along the semi-circular groove for a distance. The ends of the bamboo chopsticks can also be polished to make the edges and corners of the bamboo chopsticks more rounded, improving the feel of the bamboo chopsticks.

[0011] Preferably, the inner surface of the channel is provided with a plurality of ridges, the length of the ridges being consistent with the length of the channel. In this embodiment, when the bamboo chopsticks slide circumferentially along the inner wall of the channel, the ridges can disturb and stir the bamboo chopsticks in the channel, thereby enabling the stacked bamboo chopsticks to be interchanged.

[0012] Preferably, the shaking device includes a frame, on which a motor is mounted, with a support column fixedly mounted vertically and coaxially to the motor output shaft. A transmission plate is fixedly connected to the support column. The upper surface of the transmission plate is inclined, and a connecting column is rotatably connected above the transmission plate. The lower surface of the connecting column is in parallel contact with the inclined upper surface of the transmission plate. The end of the connecting column, remote from the transmission plate, is fixedly connected to the bottom of the housing, and the axes of the connecting column and the support column are non-parallel. The bottom of the housing is also provided with a limit device to prevent the housing from rotating with the transmission plate. In this embodiment, the upper surface of the transmission plate is inclined so that the axis of the connecting column and the axis of the motor output shaft form an angle greater than 0°. When the motor rotates, and under the constraints of the limit device, the housing shakes in multiple directions.

[0013] Preferably, the limiting device includes springs fixed at the four corners of the bottom of the housing, with the lower ends of the springs fixed to the upper surface of the frame. In this solution, the springs fixed to the bottom of the housing can prevent the housing from rotating with the rotation of the transmission plate, and when the housing shakes, they do not hinder the shaking of the housing and can provide a certain support force for the housing.

[0014] Preferably, the transmission plate is elongated, with the support and connecting columns located near each end of the transmission plate. In this embodiment, the longer the transmission plate, the greater the eccentricity between the connecting and supporting columns. As the motor drives the support columns to rotate, the greater the housing shakes. The length of the transmission plate can be designed based on the desired degree of shake.

[0023] like Figure 1 As shown, a bamboo chopstick surface polishing device for processing bamboo chopsticks includes a frame 1, a shaking device is provided on the frame 1, a shell 3 is fixed on the shaking device, a cylindrical channel 34 is opened inside the shell 3, the bamboo chopsticks to be polished are placed in the channel 34, the inner wall of the channel 34 is roughened, when the bamboo chopsticks move in the channel 34, the rough inner wall polishes the surface of the bamboo chopsticks, a plurality of ridges 35 are evenly distributed on the inner surface of the channel 34, the length direction of the ridges 35 is consistent with the length direction of the channel 34, a cover plate 31 for closing the two ends of the channel 34 is provided on the outside of the shell 3 and at both ends of the channel 34, one side of the cover plate 31 is hinged to the surface of the shell 3 by a hinge, and the other side is fixed with a connecting plate, and the connecting plate is bolted to the surface of the shell 3. In some embodiments, if it is convenient to open and close the cover plate 31, the connecting plate and the shell 3 can be provided with a clamping structure. In some embodiments, if it is necessary to realize automated production, the cover plate 31 and the shell 3 can be provided with a structure that can be opened and closed automatically. There are many existing technologies that can be referred to, which will not be described in detail here.

[0024] like Figure 4 As shown, a handle 32 is fixed on the side of the cover 31 away from the channel 34. The cover 31 can be easily opened and closed by holding the handle 32. A semi-circular groove 33 with a rough surface is provided on the side of the cover 31 facing the channel 34. When the shaking device is started, the shaking device can be driven to shake in multiple directions, so that the surfaces of the bamboo chopsticks inside the channel 34 rub against each other and the inner wall of the channel 34, and the ends of the bamboo chopsticks rub against the inner wall of the groove 33, so that the surface of the bamboo chopsticks is polished in all directions, and the ridges 35 can disturb the bamboo chopsticks inside the channel 34, so that when the bamboo chopsticks pile roll circumferentially in the channel 34, they have the opportunity to move to contact the inner wall of the channel 34 and be polished.

[0025] like Figure 2 、 Figure 3 As shown, the shaking device includes a motor 2 whose body is fixed inside the frame 1, and the output shaft of the motor 2 extends vertically upward from the frame 1 and is rotatably connected to the frame 1 through a bearing. The part of the output shaft extending out of the frame 1 is coaxially keyed to a support column 21. The diameter of the support column 21 is larger than the output shaft of the motor 2 and is in contact with the upper surface of the frame 1, which can provide a stable supporting force. A transmission plate 22 is fixedly connected to the support column 21, and the upper surface of the transmission plate 22 is inclined; a connecting column 23 is rotatably connected to the upper side of the transmission plate 22 through a through-axis (the specific rotating connection structure can be referred to the existing technology and will not be elaborated here), the lower surface of the connecting column 23 is in parallel contact with the inclined upper surface of the transmission plate 22, and therefore, the connecting column 23 is non-parallel to the axis of the support column 21. The end of the connecting column 23 away from the transmission plate 22 is fixedly connected to the bottom of the shell 3; the transmission plate 22 is long and narrow, and the support column 21 and the connecting column 23 are respectively close to the two ends of the transmission plate 22. In some embodiments, the transmission plate 22 can be designed to have a variety of lengths, the purpose of which is to adjust the eccentricity between the connecting column 23 and the support column 21. The longer the eccentricity between the connecting column 23 and the support column 21, the greater the shaking degree of the shell 3 during the rotation of the support column 21 driven by the motor 2; the bottom of the shell 3 is also provided with a spring 4 to prevent the shell 3 from rotating with the transmission plate 22. There are four springs 4, which are respectively fixed at the four corners of the bottom of the shell 3. The lower end of the spring 4 is fixed to the upper surface of the frame 1, which does not hinder the shaking of the shell 3 and can provide a certain supporting force for the shell 3.

[0026] In order to prevent the bamboo chopsticks from getting tangled together while moving in the channel 34 , experiments have shown that the height of the stacked bamboo chopsticks does not exceed 1 / 4 of the diameter of the channel 34 .

[0027] From the above, it can be seen that the specific working principle of the utility model is as follows:

[0028] The ground bamboo chopsticks are poured into the channel 34 in the shell body 3, the cover plates 31 at both ends of the channel 34 are closed, and the shaking device is started. Specifically, the motor 2 starts to rotate, driving the support column 21 and the transmission plate 22 to start rotating. Because the axis of the connecting column 23 and the axis of the support column 21 have an angle greater than 0°, and the connecting column 23 and the support column 21 have a certain eccentricity, under the limitation of the four springs 4 at the bottom of the shell body 3, the rotation of the transmission plate 22 drives the shell body 3 to start shaking, and the shaking directions are multiple, so that the two ends of the channel 34 have a height difference during the shaking process, so that the bamboo chopsticks can slide back and forth in the channel 34 along the length direction of the channel 34, and the surface of the bamboo chopsticks is ground and polished along the length direction of the bamboo chopsticks, thereby promoting the removal of burrs on the bamboo chopsticks, and in the process of the bamboo chopsticks sliding along the channel 34, the end contacts the inner wall of the groove 33 of the cover plate 31 and slides a distance, so that the end corners of the bamboo chopsticks are rounded;

[0029] During the sliding process, the bamboo chopsticks can also roll along the cylindrical inner wall of the channel 34. On the one hand, the bamboo chopsticks rub against the inner wall of the channel 34 and rub against each other, so that the bamboo chopsticks are polished circumferentially. On the other hand, the stacked bamboo chopsticks roll along the inner wall. Under the disturbance of the ridges 35, the bamboo chopsticks stacked on the upper layer can exchange positions with the bamboo chopsticks on the bottom layer that are attached to the inner wall of the channel 34 during repeated rolling. All bamboo chopsticks have the opportunity to rub against the inner wall of the channel 34, so that all bamboo chopsticks poured into the channel 34 are polished more fully.

[0030] After polishing, the cover 31 is opened and the bamboo chopsticks are poured out from the channel 34 to enter the next processing step.

[0031] The above is only an embodiment of the present invention, and the common knowledge of the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
