[0005] To achieve the above-mentioned purpose, the polishing device for bamboo product processing proposed in the utility model includes a support frame, a roller and a driving assembly. The roller is rotatably mounted on the support frame through rotating shafts on both sides. The driving assembly is connected to the roller. A feed port is provided on the roller, and a cover plate is provided at the feed port. A slide rail is provided on the roller, and a slider corresponding to the slide rail is provided on the back of the cover plate. Connecting rods are hinged on both sides of the roller, one end of the connecting rod is connected to a spring, and the other end of the spring is fixedly connected to the side wall of the roller. The other end of the connecting rod is hinged to the cover plate, and the cover plate is provided with locking blocks evenly distributed in the same straight line, and the roller is provided with a locking piece corresponding to the locking block. Through the cooperation of the slide rail and the slider, the cover can flip and slide on the slide rail.

[0011] A further optimized technical solution is provided in which a lock hole is provided on the side wall of the lock block, and the lock element includes a lock rod, a lock tongue, a fixed block, a push-pull support rod, and a push-pull drive rod. The lock rod is horizontally movable on the roller through the fixed block, and the lock tongue is in an inverted L-shaped structure. One end of the lock tongue is vertically fixedly connected to the lock rod, and the other end of the lock tongue corresponds to the lock hole. One end of the lock rod is hinged to the push-pull support rod, and the other end of the push-pull support rod is hinged to one end of the push-pull drive rod. The middle part of the push-pull drive rod is hinged to the roller through a locking shaft, and a second handle is vertically connected to one end of the locking shaft. The push-pull drive rod is driven to rotate by the second handle, and while rotating, the push-pull support rods on the left and right sides respectively push the lock rod to move left and right, so that the lock tongue on the lock rod is inserted into the lock hole to close, lock, or unlock the cover, thereby improving ease of use.

[0012] According to a further optimized technical solution, the rotating shaft is a hollow shaft, a rotary joint is connected to the rotating shaft, and a liquid inlet pipe is connected to the rotary joint. Abrasives, bamboo mildew inhibitors or cleaning agents are added to the drum through the liquid inlet pipe.

[0013] Further optimizing the technical solution, the drive assembly includes a drive motor, a reducer, and a transmission belt. The output end of the drive motor is connected to the input end of the reducer, and the output end of the reducer is connected to the rotating shaft via the transmission belt. The rotating shaft is provided with a circular grating. The circular grating detects the rotation angle of the drum, facilitating the rotational positioning of the drum.

[0014] To further optimize the technical solution, a collecting trough is provided just below the drum, and a separation net is provided at the bottom of the collecting trough. The polished bamboo poles are collected through the collecting trough, and impurities generated by polishing are separated through the separation net.

[0026] See also Figures 1 to 5In one embodiment, a polishing device for processing bamboo products disclosed herein comprises a support frame 1, a roller 2 and a driving assembly 3. The roller 2 is rotatably mounted on the support frame 1 via rotating shafts 201 on both sides. The driving assembly 3 is connected to the roller 2 and is used to drive the roller 2 to rotate. A feed port 202 is provided on the roller 2. A cover plate 203 is provided at the feed port 202. The cover plate 203 is used to close or open the feed port 202 so that the bamboo pole to be polished can be placed in the roller 2 for rolling grinding and polishing. Specifically, a sealing groove 203 is provided around the feed port 202. 16. A sealing ring is provided in the sealing groove 2016. When the cover plate 203 closes the feed port 202, the sealing ring is pressed to seal. A slide rail 204 is provided on the roller 2. A slider 205 corresponding to the slide rail 204 is provided on the back of the cover plate 203. By cooperating with the slide rail 204 and the slider 205, the cover plate 203 can flip and slide on the slide rail 204. Connecting rods 206 are hinged on the two outer side walls of the roller 2. A spring 207 is connected to one end of the connecting rod 206. The other end of the spring 207 is fixedly connected to the side wall of the roller 2. The other end of the connecting rod 206 is hinged to the side wall of the free end of the cover plate 203. Specifically, the connecting rod 206 is an inverted L-shaped rod structure, with the hinge point of the connecting rod 206 and the roller 2 as the fulcrum, one end of the spring 207 is fixed to the short side of the connecting rod 206, that is, one end of the resistance wall, and one end of the power arm of the connecting rod 206 is hinged to the cover plate 203. When the cover plate 203 covers the feed port 202, the cover plate 203 is pulled down to slide to the end of the slide rail 204 close to the feed port 202 and flipped downward to cover the entire feed port 202. At this time, the connecting rod 206 is synchronously flipped downward to stretch the spring 207. When the cover 203 opens the feed port 202, the cover 203 is slightly lifted up. Under the action of the rebound force of the spring 207, the connecting rod 206 is flipped backward to drive the cover 203 to flip upward and slide backward along the slide rail 204, and the spring retracts; locking blocks 208 are evenly distributed in the same straight line on the free end of the cover 203, and locking pieces 209 corresponding to the locking blocks 208 are provided on the roller 2. The cover 203 is locked after closing the feed port 202 through the cooperation of the locking blocks 208.In this embodiment, when polishing work is required, the cover plate 203 is slightly lifted manually, and the connecting rod 206 is flipped backward under the action of the rebound force of the spring 207, driving the cover plate 203 to flip upward and slide backward along the slide rail 204. The entire cover plate 203 is stacked on the outer surface of the cover plate 203, and then a large number of bamboo poles to be polished are put into the drum 2, and the cover plate 203 is pulled down to slide to the end of the slide rail 204 close to the feed port 202 and flipped downward to cover the entire feed port 202. At this time, the connecting rod 206 is synchronously flipped downward to stretch the spring 207, and then locked through the cooperation of the lock 209 and the lock block 208, and the drive assembly 3 can be started to drive and rotate with the drum 2, so that more bamboo poles can be subjected to rolling friction polishing at the same time, effectively improving the polishing efficiency, and the opening and closing process of the cover plate 203 does not require much effort to operate, saving time and effort, and facilitating operation for the operator.

[0027] In the specific example, the drum 2 is an octagonal cylindrical structure, the feed port 202 is opened on one edge of the octagonal cylindrical structure, and the slide rail 204 is provided on the outer edge adjacent to the feed port 202. After the cover plate 203 is opened, the entire cover plate 203 can be stacked on one edge of the octagonal cylindrical structure. Of course, the drum 2 can also be a hexagonal cylindrical structure. Since the drum 2 with an octagonal cylindrical structure has more edges and corners, its processing effect is better and the processing and polishing effect can be achieved more quickly. The octagonal cylindrical structure is preferably used here. The bamboo poles put into the drum 2 are subjected to rolling friction with each other and friction with the inner wall of the drum 2, so that the surface of the bamboo poles can be polished.

[0028] In a specific example, a slide groove 2041 is provided on both sides of the slide rail 204, and a slide shaft 2051 is provided on the slider 205 to extend into the slide groove 2041. The slide shaft 2051 can slide and rotate within the slide groove 2041, so that the cover plate 203 can slide along the slide groove 2041 and be stacked on the outer surface of the drum 2 without occupying a large space, and can also be flipped to cover the feed port 202.

[0029] In a preferred embodiment, a roller 2052 is sleeved on the slide shaft 2051. The sliding movement between the slide shaft 2051 and the slide groove 2041 is changed to rolling, thereby reducing friction resistance and making it easier for the cover plate 203 to be stacked.

[0030] In a preferred embodiment, a first handle 2061 is connected to one end of the connecting rod 206 where the cover plate 203 is hinged. The first handle 2061 is vertically connected to the connecting rod 206, making it convenient for the operator to hold the first handle 2061 and pull down or push up the cover plate 203 to perform the switch operation.

[0031] In a preferred embodiment, fixing ears 2010 are provided on both side walls of the drum 2. Each fixing ear 2010 has a slot 2011 corresponding to the first handle 2061. A pin hole 2012 extending through the slot 2011 is provided on the side wall of the fixing ear 2010. A latch 2013 is movably disposed within the pin hole 2012. When the cover 203 opens the feed opening 202 and overlaps the outer edge of the drum 2, the first handle 2061 flips over and fits within the slot 2011. At this point, the latch 2013 is inserted into the pin hole 2012, locking the first handle 2061 and preventing it from flipping backward. This keeps the cover 203 fixed to the outer edge of the drum 2, facilitating the rolling of the drum 2 to empty or load the polished bamboo poles.

[0032] In a specific example, a lock hole 2081 is provided on the side wall of the lock block 208, and the lock element 209 includes a lock rod 2091, a lock tongue 2092, a fixed block 2093, a push-pull support rod 2094 and a push-pull drive rod 2095. The lock rod 2091 is horizontally movable through the fixed block 2093 and is arranged on the edge of the roller 2 near the feed port 202. The lock tongue 2092 is an inverted L-shaped structure. One end of the lock tongue 2092 is vertically fixedly connected to the lock rod 2091, and the other end of the lock tongue 2092 corresponds to the lock hole 2081. One end of the lock rod 2091 is hinged to the push-pull support rod 2094, and the other end of the push-pull support rod 2094 is hinged to one end of the push-pull drive rod 2095. The middle part of the push-pull drive rod 2095 is hinged to the roller 2 through the locking shaft 2096, and a second handle 2097 is vertically connected to one end of the locking shaft 2096. During use, the operator holds the second handle 2097 to drive the locking shaft 2096 to rotate clockwise, and the push-pull drive rod 2095 rotates synchronously. While rotating, the push-pull support rods 2094 on the left and right sides push the locking rod 2091 to the left and right respectively, so that the lock tongue 2092 on the locking rod 2091 is inserted into the lock hole 2081 to close and lock the cover 203, thereby improving ease of use.

[0033] In a preferred embodiment, the rotating shaft 201 is a hollow shaft, a rotary joint 2014 is connected to the rotating shaft 201, and a liquid inlet pipe 2015 is connected to the rotary joint 2014. Specifically, the rotating shaft 201 away from one end of the driving assembly 3 is a hollow shaft connected to the interior of the drum 2, so that one end of the liquid inlet pipe 2015 can be connected to the interior of the drum 2. When it is necessary to add abrasive to the drum 2 to further improve the polishing efficiency, it can be added through the liquid inlet pipe 2015 when the drum 2 stops rotating. It can also be added through the liquid inlet pipe 215 to prevent mildew of the bamboo, and it can also be added through the liquid inlet pipe 215 to clean the bamboo pole.

[0034] In this specific example, the drive assembly 3 includes a drive motor 301, a speed reducer 302, and a transmission belt 303. The output of the drive motor 301 is connected to the input of the speed reducer 302, which in turn is connected to the rotating shaft 201 via the transmission belt 303. A circular grating 304 is provided on the rotating shaft 201. Specifically, the drive motor 301 is a three-phase asynchronous motor controlled by frequency conversion. The circular grating 304 detects the angle of rotation of the drum 2 and feeds it back to the PLC controller. The PLC controller then sends a control signal to the frequency converter to control the rotation of the drive motor 301, achieving closed-loop control and facilitating the rotational positioning of the drum 2.

[0035] In a preferred embodiment, a collecting trough 4 is provided directly below the drum 2, and a separating net 401 is provided at the bottom of the collecting trough 4. After the bamboo poles are poured out of the drum 2, they enter the collecting trough 4 below and fall onto the separating net 401. The polished impurities pass through the separating net 401, thereby facilitating separation of the polished impurities.
