Description

Technical Field

[0001] This invention relates to the technical field of bamboo product processing equipment, and more particularly to a bamboo joint removal device for bamboo product processing. Background Technology

[0002] In the field of bamboo product processing, the removal of bamboo nodes is a crucial step. As a natural material, bamboo has interspersed nodes in its internal structure. These nodes not only affect the appearance of the bamboo but also limit the design freedom and application range of bamboo products. Therefore, effective treatment of bamboo nodes is necessary when making high-quality bamboo products.

[0003] Existing bamboo node removal techniques mainly employ two methods. The first method involves manual operation by workers who hold a knife against the surface of the bamboo node with one hand and rotate the bamboo with the other to cut off the node. Although this method seems simple and direct, the actual operation is complex and delicate. Because the position and shape of each bamboo node are different, workers need to concentrate highly and adjust the angle and force of the knife according to the specific situation. This not only increases the labor intensity but also raises the skill requirements for workers. In addition, manual operation is slow, especially when facing the demand for large-scale bamboo product processing, which leads to low work efficiency and increased production costs.

[0004] The second method is to use a specially designed bamboo joint polishing device. This type of device uses mechanical force to polish the surface of the bamboo to remove the bamboo joints. Compared with manual operation, the bamboo joint polishing device can improve work efficiency and reduce labor intensity to a certain extent. However, the use of this device still depends on manual loading and unloading. That is, workers need to frequently put bamboo into the equipment and take out the processed finished product. This process is also time-consuming and labor-intensive. In addition, bamboo joint polishing devices are usually large in size and take up a lot of space. Such equipment is not suitable for small processing plants or environments with limited work space. Summary of the Invention

[0005] In view of this, the present invention provides a bamboo node removal device for bamboo product processing, which can overcome the disadvantages of existing bamboo node removal technology, such as cumbersome operation, low work efficiency, and large size of bamboo node polishing device, which takes up a lot of space.

[0006] The technical implementation of the present invention is as follows: a bamboo node removal device for bamboo product processing, comprising a handle, a battery, a drive motor, a gearbox, a grinding wheel, a control switch, a rotating assembly, and a limiting assembly. The battery is slidably mounted on the end of the handle, the drive motor and the gearbox are mounted on the end of the handle away from the battery, the output shaft of the drive motor is connected to the input end of the gearbox, and the gearbox has two symmetrically arranged output ends.

The fixed frame is connected to the handle, the hollow tube is symmetrically slidably connected to the fixed frame, the connecting spring connects the fixed frame and the hollow tube, and the arc-shaped limiting plate is connected to the lower end of the hollow tube.

[0009] In a preferred embodiment of the present invention, the invention further includes an airbag, a connecting tube, a rotating plate, a control component, and a pressing component. The airbag is mounted on the arc-shaped limiting plate. The connecting tube connects the airbag and the hollow tube and maintains communication. The rotating plate is rotatably connected to the arc-shaped limiting plate, and one end of the airbag is fixedly connected to the side of the rotating plate. The control component is used to control the airbag to expand or contract, and the pressing component is used to press down the end of the airbag away from the rotating plate.

[0010] In a preferred embodiment of the present invention, the control component includes a connecting rod and a piston rod. The connecting rod is symmetrically connected to the top of the fixed frame, and the piston rod is connected to the connecting rod and can slide inside the hollow tube.

[0011] In a preferred embodiment of the present invention, the pressing component includes a mounting rod, a sliding rod, a pressure plate, and a return spring. The mounting rod is connected to the top of the arc-shaped limiting plate, the sliding rod is slidably connected to the mounting rod, the pressure plate is connected to the lower end of the sliding rod, and the pressure plate contacts the end of the airbag away from the rotating plate. The return spring connects the pressure plate and the mounting rod.

[0012] In a preferred embodiment of the present invention, a protective shell is further included, with two protective shells symmetrically connected to both sides of the gearbox, and the grinding wheel and the barbed swivel ring located inside the two protective shells respectively.

[0013] In a preferred embodiment of the present invention, a roller is further included, which is rotatably connected to the arc-shaped limiting plate and the rotating plate respectively.

[0027] Example: A bamboo joint removal device for processing bamboo products, such as... Figures 1-4 As shown, the device includes a handle 1, a battery 2, a drive motor 3, a gearbox 4, a grinding wheel 5, a control switch 6, a rotation component, and a limit component. The battery 2 is slidably mounted on the rear end of the handle 1 for easy battery replacement. The drive motor 3 is mounted on the front side inside the handle 1, and the battery 2 powers the drive motor 3. The gearbox 4 is mounted on the front end of the handle 1, and the output shaft of the drive motor 3 is connected to the input end of the gearbox 4. The gearbox 4 has two symmetrical output ends 401. The gearbox 4 is a mature existing technology and will not be described in detail here. The grinding wheel 5 is detachably mounted on the output end 401 on the right side of the gearbox 4, so that the drive motor 3 can drive the grinding wheel 5 to rotate and grind and remove the bamboo nodes on the bamboo through the gearbox 4. The grinding wheel 5 can be freely replaced after it wears down to a certain extent. The control switch 6 is mounted in the middle of the right side of the handle 1. The control switch 6 is used to control the start and stop of the drive motor 3. The rotation component is used to drive the bamboo to rotate, and the limit component is used to limit the bamboo.

[0028] like Figure 3As shown, the rotating assembly includes a connecting plate 7, a driving gear 8, a connecting frame 9, a driven gear 10, a barbed swivel ring 11, and an internal gear ring 12. The connecting plate 7 is detachably mounted on the output end 401 on the left side of the gearbox 4. The driving gear 8 is connected to the right side of the connecting plate 7. The connecting frame 9 is connected to the front end of the handle 1. The left side of the connecting frame 9 is circumferentially rotatably connected to three driven gears 10, and the driven gears 10 mesh with the driving gear 8. The barbed swivel ring 11 is rotatably connected to the connecting plate 7. The internal gear ring 12 is connected to the inner side of the barbed swivel ring 11, and the internal gear ring 12 meshes with the driven gear 10.

[0029] like Figure 4 As shown, the limiting assembly includes a fixed frame 13, a hollow tube 14, a connecting spring 15, and an arc-shaped limiting plate 16. The fixed frame 13 is connected to the front of the handle 1. Hollow tubes 14 are slidably connected to both the left and right sides of the fixed frame 13. The hollow tubes 14 are shaped like an I-beam, and the upper end of the hollow tubes 14 passes through the top of the fixed frame 13. The connecting springs 15 are wrapped around the outer sides of both hollow tubes 14, and the two ends of the connecting springs 15 are connected to the fixed frame 13 and the hollow tubes 14 respectively. The lower ends of both hollow tubes 14 are connected to the arc-shaped limiting plate 16.

[0030] like Figure 5 and Figure 6 As shown, it also includes an airbag 17, a connecting tube 18, a rotating plate 19, a control assembly, and a pressing assembly. An airbag 17 is mounted on the front of each of the two arc-shaped limiting plates 16. The airbag 17 is cylindrical, and each airbag 17 corresponds to one of the two hollow tubes 14. A connecting tube 18 connects each airbag 17 to its corresponding hollow tube 14, maintaining communication. A rotating plate 19 is rotatably connected to the bottom center of each arc-shaped limiting plate 16. The curvature of the rotating plate 19 matches that of the arc-shaped limiting plate 16, ensuring that the top of the rotating plate 19 is flush against the front bottom of the arc-shaped limiting plate 16. The lower end of the airbag 17 is fixedly connected to the top of the rotating plate 19. The control assembly controls the expansion or contraction of the airbag 17, and the pressing assembly presses down on the end of the airbag 17 furthest from the rotating plate 19. The control assembly includes a connecting rod 20 and a piston rod. 21. Connecting rods 20 are connected to the top left and right sides of the fixed frame 13. The connecting rods 20 are in the shape of an inverted U. Piston rods 21 are connected to the inner side of the two connecting rods 20. The two piston rods 21 correspond one-to-one with the two hollow tubes 14. The piston rods 21 can slide inside the hollow tubes 14. Their outer diameter is designed to match the inner diameter of the hollow tubes 14. The pressing assembly includes mounting rods 22, sliding rods 23, pressure plates 24 and return springs 25. Mounting rods 22 are connected to the top front side of the two arc-shaped limiting plates 16. Sliding rods 23 are slidably connected to the middle of the two mounting rods 22. Pressure plates 24 are connected to the lower end of the two sliding rods 23. The bottom of the pressure plates 24 contacts the top of the airbag 17. Return springs 25 are wrapped around the outer side of the two sliding rods 23. The two ends of the return springs 25 are connected to the pressure plates 24 and mounting rods 22 respectively.

[0031] like Figure 7 and Figure 8 As shown, it also includes a protective shell 26 and rollers 27. The protective shells 26 are detachably installed on both the left and right sides of the gearbox 4. The grinding wheel 5 and the barbed ring 11 are located inside the two protective shells 26 respectively. The protective shells 26 are used to prevent workers from accidentally touching the grinding wheel 5 and the barbed ring 11 and getting injured. They can also prevent debris from flying during the processing. The rear of the two arc-shaped limiting plates 16 are rotatably connected to two rollers 27, and the front of the two rotating plates 19 are also rotatably connected to rollers 27.

[0032] First, a worker holds handle 1 and places the arc-shaped limiting plate 16 on the bamboo, ensuring the bottom rear side of the arc-shaped limiting plate 16 contacts the bamboo surface. Then, the worker presses down on handle 1, causing the grinding wheel 5, the barbed rotating ring 11, and the fixing frame 13 to move downwards. This compresses the connecting spring 15, and the fixing frame 13 causes the connecting rod 20 and the piston rod 21 to move downwards. The piston rod 21 then compresses the air inside the hollow tube 14, allowing the air inside the hollow tube 14 to enter the airbag 17 through the connecting tube 18, causing the airbag 17 to inflate. Because the airbag 17, its sides, and the top are restricted by the arc-shaped limiting plate 16 and the pressure plate 24 respectively, only the bottom of the airbag 17 can extend downwards and inflate. The rotating plate 19 will rotate downwards and contact the bamboo surface. The arc-shaped limiting plate 16 and the rotating plate 19 work together to limit the bamboo and prevent it from moving randomly. At the same time, the rollers 27 on the arc-shaped limiting plate 16 and the rotating plate 19 will contact the bamboo surface. At this time, the rotating plate 19 will stop rotating downwards, that is, the bottom of the airbag 17 can no longer extend downwards. If the fixing frame 13 is still moving downwards, the top of the airbag 17 will start to extend upwards and expand, thereby pushing the pressure plate 24 upwards and compressing the return spring 25. When the barbed ring 11 contacts the bamboo surface, the spikes on the surface of the barbed ring 11 will pierce the bamboo surface, and the grinding wheel 5 will contact the bamboo nodes. Then, the worker presses the control switch 6 to start the drive motor 3. The drive motor 3, through the gearbox 4, drives the grinding wheel 5 to rotate and grind away the bamboo nodes. Simultaneously, the gearbox 4 drives the connecting disc 7 and the driving gear 8 to rotate. The driving gear 8 drives the driven gear 10, the internal gear ring 12, and the barbed ring 11 to rotate in opposite directions. That is, the grinding wheel 5 and the barbed ring 11 rotate in opposite directions. The barbed ring 11 causes the bamboo to rotate 360 ​​degrees in the opposite direction between the arc-shaped limiting plate 16 and the rotating plate 19, allowing the grinding wheel 5 to remove the bamboo nodes from all angles. This allows the worker to remove the bamboo nodes with one hand, making the operation simple and convenient, and improving efficiency. In terms of work efficiency, after the bamboo joints are removed, release the control switch 6, the drive motor 3 stops working, and then lift the handle 1 upwards. The handle 1 can drive the grinding wheel 5, the barbed rotating ring 11 and the fixing frame 13 to move upwards and reset, so that the grinding wheel 5 and the barbed rotating ring 11 are separated from the surface of the bamboo. The fixing frame 13 can drive the connecting rod 20 and the piston rod 21 to move upwards and reset. The piston rod 21 can draw the air in the airbag 17 back into the hollow tube 14 through the connecting tube 18, so that the airbag 17 contracts and returns to its original state. The lower end of the airbag 17 will drive the rotating plate 19 to rotate upwards and reset, and the upper end of the airbag 17 will separate from the pressure plate 24. At this time, the reset spring 25 will return to its original state, driving the sliding rod 23 and the pressure plate 24 to move downwards and reset.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
