Description

Technical Field

[0001] This invention relates to the field of bamboo product processing technology, and in particular to a cutting device for bamboo product processing. Background Technology

[0002] The bamboo used to make bamboo flutes is generally selected from bamboos such as the three-year-old bitter bamboo. Workers select suitable bamboo in the bamboo forest, cut it down, and transport it out of the bamboo forest to the designated location by truck. In order to save transportation space, the bamboo is pre-treated before loading and transportation.

[0003] The existing technology involves workers using knives to cut off the bamboo branches. However, if the process starts from the bottom of the bamboo and works towards the top, the branches are often messy and tilted upwards, resulting in long, sharp branches remaining on the main stem after cleaning. These sharp branches can easily injure workers and can also cause the bamboo to slide against each other during transport, potentially scratching the main stem. If the branches are cleaned from the top towards the base, the outer skin may be scraped off, damaging the bamboo and rendering it unusable for making bamboo flutes, thus resulting in waste. Summary of the Invention

[0004] To overcome the disadvantages of long bamboo branches remaining on the main stem of bamboo easily injuring workers, and the bamboo surface being easily scratched or the bamboo skin being scraped off during the manual cutting of the main stem, rendering the bamboo unusable, this invention provides a cutting device for bamboo product processing.

[0005] The technical solution of the present invention is as follows: a cutting device for bamboo product processing, comprising a support frame; further comprising a guide ring, a connecting plate, a cutter, a connecting ring, a first fixing ring, a connecting rod, a fixing rod, a lead screw, a first linear drive component, and a drive assembly; a plurality of fixing rods are fixedly connected to the support frame; all fixing rods are fixedly connected to a connecting ring; a first fixing ring is fixedly connected to the connecting ring; a plurality of connecting rods are connected to the first fixing ring via torsion springs, and a guide ring for guiding bamboo branches is fixedly connected to all connecting rods, and the guide ring is made of flexible material; the guide ring is located in front of the connecting ring; a lead screw is fixedly connected to both the left and right sides of the support frame; a slider is slidably connected to each lead screw; a first linear drive component is fixedly connected to each slider; a connecting plate is fixedly connected to the output end of each first linear drive component; a drive assembly is provided on the connecting plate; a cutter for cutting bamboo branches is connected to the drive assembly; the drive assembly is used to drive the cutter to move.

[0006] Furthermore, it is particularly preferred that the drive assembly includes an arc-shaped slide rail, a second linear drive, and a third linear drive; an arc-shaped slide rail is fixedly mounted on each connecting plate, and all the arc-shaped slide rails together form a circular guide rail; a second linear drive is fixedly mounted on the arc-shaped slide rail via a slider; a third linear drive is fixedly mounted on the output end of the second linear drive; a motor is fixedly mounted on the output end of the third linear drive via a support plate; and a cutter is fixedly mounted on the output end of the motor.

[0007] Furthermore, it is particularly preferred that the guide ring is tapered.

[0008] Furthermore, it is particularly preferred that the device also includes a first airbag, an air pump, and a second airbag; a first airbag for limiting the position of the bamboo trunk is fixedly connected to the connecting ring; the first airbag is located behind the guide ring; a second airbag for limiting the position of the bamboo trunk is fixedly connected to each connecting plate, and all the second airbags form a circular support frame on which an air pump is fixedly connected; a collection box is provided on the support frame, and an air guide tube is placed inside the collection box.

[0009] In addition, it is particularly preferred that both the first and second airbags are made of wear-resistant materials.

[0010] Furthermore, it is particularly preferable that a distance sensor is provided on the underside of the cutter.

[0011] Furthermore, it is particularly preferred that the device also includes a limiting plate, a fixing block, and a rubber strip; the connecting plate is located in front of the guide ring; a fixing block is fixedly attached to each connecting plate; all the fixing blocks together form a ring; each fixing block is movably connected to several limiting plates for limiting the bamboo branches via torsion springs; all the limiting plates on each fixing block are together fixedly attached to a rubber strip for limiting the bamboo branches, and the surface of the rubber strip is rough; the rubber strip is easier to deform and stretch than the guide ring.

[0012] Furthermore, preferably, it also includes a first limiting ring, a protrusion, a second fixing ring, a fourth linear drive member, and a second limiting ring; the second fixing ring is fixedly connected to the connecting ring; the second fixing ring is located in front of the first airbag; two fourth linear drive members are fixedly connected to the second fixing ring; the output ends of all fourth linear drive members are fixedly connected to the second limiting ring; the second limiting ring is located in front of the second fixing ring; a plurality of first limiting rings are connected to the connecting rod by springs; and a plurality of protrusions are fixedly connected to each first limiting ring.

[0013] Furthermore, it is particularly preferred that the second limiting ring is configured in an umbrella shape.

[0014] Furthermore, it is particularly preferred that the second limiting ring is made of a rigid material.

[0015] The beneficial effects of this invention are as follows: This invention achieves the guidance of bamboo branches through a guide ring, and further cuts the bamboo branches by driving the cutter through an arc-shaped slide rail and a third linear drive component. This solves the problem that the surface of bamboo is scratched when workers perform preliminary processing on bamboo in existing equipment. It also solves the problem that long bamboo branches remain on the main stem of bamboo when workers perform preliminary processing on bamboo, which can poke the handling workers and cause bamboo branches to scratch the main stem of bamboo during transportation due to relative movement between bamboos.

[0016] The first and second airbags are used to fix the bamboo main stem on both sides to prevent the bamboo main stem from shaking during the cutting process, which would result in uneven cuts and reduce the difficulty of cutting.

[0017] The second limiting plate drives the rubber strip to limit the bamboo branches, which solves the problem that when the cutter cuts the bamboo branches, the bamboo branches slip through the gaps between the second limiting plates because the bamboo is messy and has thin branches, making it impossible for the cutter to cut the bamboo branches.

[0018] The first limiting ring and the protrusion increase the friction between the guide ring and the rubber strip and the bamboo, thereby improving the fixing effect on the bamboo. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0033] Example 1

[0034] like Figures 1-4 , Figure 6 and Figure 12 As shown, a cutting device for processing bamboo products includes a support frame 1;

[0035] It also includes a guide ring 2, a connecting plate 3, a cutter 4, a connecting ring 101, a first fixing ring 102, a connecting rod 103, a fixing rod 104, a lead screw 201, a first linear drive component 202, and a drive assembly; a plurality of fixing rods 104 arranged in a circular array are fixedly connected to the support frame 1; all fixing rods 104 are fixedly connected to a connecting ring 101; a first fixing ring 102 is fixedly connected to the connecting ring 101; a plurality of connecting rods 103 arranged in a circular array are connected to the first fixing ring 102 by a torsion spring, and a common connecting rod 104 is fixedly connected to a lead screw 201. A guide ring 2, which is made of flexible material, is located in front of the connecting ring 101. A lead screw 201 is bolted to both the left and right sides of the support frame 1. A slider is slidably connected to each lead screw 201. A first linear drive 202 is fixedly connected to each slider. The first linear drive 202 is an electric push rod or an electric telescopic rod. A connecting plate 3 is fixedly connected to the output end of each first linear drive 202. A drive assembly is provided on the connecting plate 3. A cutter 4 is connected to the drive assembly. The drive assembly is used to drive the cutter 4 to move.

[0036] The drive assembly includes an arc-shaped slide rail 206, a second linear drive component 207, and a third linear drive component 208. Each connecting plate 3 is bolted with an arc-shaped slide rail 206, and all the arc-shaped slide rails 206 together form a circular guide rail. The second linear drive component 207 is bolted to the arc-shaped slide rail 206 via a slider. The output end of the second linear drive component 207 is fixedly connected to the third linear drive component 208. The output end of the third linear drive component 208 is fixedly connected to a motor via a support plate. The output end of the motor is fixedly connected to a cutter 4. Both the third linear drive component 208 and the second linear drive component 207 are electric push rods or electric telescopic rods.

[0037] The guide ring 2 is cone-shaped to guide the bamboo branches and prevent them from sticking to the main stem.

[0038] It also includes a first airbag 105, an air pump 106, and a second airbag 203; the first airbag 105 is fixedly connected to the connecting ring 101; the first airbag 105 is located behind the guide ring 2; a second airbag 203 is fixedly connected to each connecting plate 3, and all the second airbags 203 form a ring; the air pump 106 is fixedly connected to the support frame 1; a collection box is provided on the support frame 1, and an air guide tube is placed in the collection box; during operation, the air pump 106 is connected to the first airbag 105 and the second airbag 203 respectively by the worker using the air guide tube.

[0039] Both the first airbag 105 and the second airbag 203 are made of wear-resistant materials, which increases the service life of the device.

[0040] A distance sensor is installed on the lower side of the cutter 4 to determine the position of the cutter 4 relative to the bamboo branches.

[0041] The cutting device used for processing bamboo products will be referred to as the device below.

[0042] Before workers load the cut bamboo onto the truck, they need to remove excess bamboo branches. This invention places the device next to the truck before work begins, and the truck supplies power to the device.

[0043] This invention involves workers selecting suitable locations on the cut bamboo and cutting off the thinner upper part of the bamboo that is unsuitable for making bamboo flutes. Then, the workers pass the upper part of the bamboo through a connecting plate 3. At this point, the connecting plate 3 is in the following state: Figure 11 As shown, workers then pass the bamboo through the guide ring 2 and the connecting ring 101, and manually push and pull the bamboo at the front and rear of the device to make the bamboo pass through the device for preliminary processing.

[0044] During this process, the bamboo compresses the guide ring 2, which in turn drives the connecting rod 103 to expand outward around the connection point between the first fixed ring 102 and the connecting rod 103. This expands to accommodate the size of the bamboo trunk, ensuring that the guide ring 2 remains in close contact with the bamboo trunk. The guide ring 2 guides the bamboo branches, causing them to move upward along the surface of the guide ring 2, thus erecting the bamboo branches. When the worker is unable to push or pull the bamboo during its movement, the guide ring 2 is located at the connection point between the bamboo branches. Figure 12 As shown, at this time, the first linear drive component 202, powered by an external power source, drives the connecting plate 3 to move towards the center of the device, as shown in the figure. Figure 1 As shown, the holes formed by the connecting plate 3 are larger than the maximum diameter of the bamboo used to make the bamboo flute. Then, the slider drives the first linear drive component 202 and other parts to slide backward along the lead screw 201 until... Figure 12 The state shown.

[0045] Furthermore, the worker removes the air duct from the collection box on the support frame 1, and connects the air pump 106 to the first airbag 105 and the second airbag 203 through the air duct. The air pump 106, powered by an external power source, pumps gas into the second airbag 203, causing the second airbag 203 to expand and clamp the front of the bamboo. At the same time, the air pump 106 pumps gas into the first airbag 105, which clamps the rear of the bamboo. This prevents the bamboo trunk from shaking when the bamboo branches are cut by the cutter 4, thus avoiding the formation of long bamboo branches after the cut bamboo is cut.

[0046] The third linear drive 208, powered by an external power source, moves the cutter 4 downwards. A distance sensor determines the distance between the cutter 4 and the bamboo trunk. A slider then drives the second linear drive 207 and other components to rotate along the arc-shaped slide rail 206. Simultaneously, the second linear drive 207 moves the cutter 4 backwards. The electric cutter 4 cuts the bamboo branches. After cutting, all components return to their original positions. Figure 11 The initial state is shown.

[0047] This invention solves the problem of bamboo being scratched during the initial processing of bamboo for making bamboo flutes, when workers use a knife to clean the branches on the main stem of the bamboo from the bottom to the top or from the top to the bottom, due to the bamboo's curvature. It also solves the problem of bamboo branches shifting during the cleaning process, resulting in long bamboo branches remaining on the cut main stem. This causes relative sliding between bamboo sections during transportation, leading to scratches on the main stem and injuries to workers who handle the bamboo.

[0048] Example 2

[0049] Based on Example 1, such as Figure 1 , Figure 2 and Figures 4-12 As shown, it also includes a limiting plate 204, a fixing block 205, and a rubber strip 306; the connecting plate 3 is located in front of the guide ring 2; a fixing block 205 is fixedly connected to each connecting plate 3; all fixing blocks 205 together form a ring; several limiting plates 204 are hinged to each fixing block 205 by a torsion spring; all limiting plates 204 on each fixing block 205 are fixedly connected to a rubber strip 306 for limiting the bamboo branches, and the surface of the rubber strip 306 is rough; the rubber strip 306 is easier to deform and stretch than the guide ring 2.

[0050] It also includes a first limiting ring 301, a protrusion 302, a second fixing ring 303, a fourth linear drive member 304, and a second limiting ring 305; the second fixing ring 303 is fixedly connected to the connecting ring 101; the second fixing ring 303 is located in front of the first airbag 105; two fourth linear drive members 304, which are symmetrically arranged vertically, are bolted to the second fixing ring 303. The fourth linear drive members 304 are electric push rods or electric telescopic rods; the output ends of all the fourth linear drive members 304 are fixedly connected to the second limiting ring 305; the second limiting ring 305 is located in front of the second fixing ring 303; three first limiting rings 301 are connected to the connecting rod 103 by springs; each first limiting ring 301 is fixedly connected to several protrusions 302.

[0051] The second limiting ring 305 is configured in an umbrella shape to fit the first limiting ring 301, so that the protrusion 302 can be lifted up to make the first limiting ring 301 protrude from the surface of the guide ring 2.

[0052] The second limiting ring 305 is made of rigid material, which makes it easy to lift the protrusion 302.

[0053] When the bamboo branches are limited by the limiting plate 204 and then cut by the cutter 4, the bamboo branches are not subjected to corresponding resistance when the cutter 4 cuts them due to the thin branches. This causes the bamboo branches to slip through the gap between the two limiting plates 204, resulting in the cutter 4 being unable to cut the bamboo branches. At the same time, because the bamboo branches are messy, the bamboo branches cannot be fully attached to the guide ring 2 when it is guided by the guide ring 2.

[0054] Therefore, in the process of the connecting plate 3 being driven closer to the guide ring 2 by the lead screw 201, the limiting plate 204 expands outward along the guide ring 2. Furthermore, the limiting plate 204 drives the rubber strip 306 to move backward along the outer surface of the guide ring 2. The rubber strip 306 then drives the bamboo branches not currently attached to the guide ring 2 to move backward, causing the bamboo branches to attach to the guide ring 2. Figure 12 As shown, the bamboo branches are straightened and fixed to facilitate the cutting of the bamboo branches by the cutting knife 4. Furthermore, since there is a certain size deviation in the main bamboo trunk used to make bamboo flutes, the size of the guide ring 2 also has a certain deviation. Therefore, the deformation of the rubber strip 306 is used to adapt to the size of the guide ring 2 and limit the bamboo branches.

[0055] Furthermore, after the bamboo branches are straightened by the rubber strip 306, because there is a certain distance between the bamboo and the guide ring 2 when the bamboo branches are against the guide ring 2, the bamboo branches will swing during the cutting process of the cutter 4, increasing the difficulty of cutting. At the same time, the cut will be uneven and have sharp corners. Therefore, when the second airbag 203 is in the form of... Figure 12 After reaching the indicated state, the second limiting ring 305 is pushed forward by the fourth linear drive member 304 with the built-in battery. The second limiting ring 305 pushes up the protrusion 302, and the protrusion 302 further drives the first limiting ring 301 to expand, as shown. Figure 12 As shown, the friction between the guide ring 2 and the bamboo branch is increased by the first limiting ring 301 and the protrusion 302 to prevent the bamboo branch from moving. At the same time, the protrusion 302 drives the first limiting ring 301 to lift the bamboo branch a second time, so that the position of the bamboo branch close to the bamboo trunk is closer to the vertical state.

[0056] The present invention addresses the problem that during the cutting process of bamboo branches by the cutter 4, the thin branches of the bamboo, lacking sufficient resistance, can slip through the gap between the two limiting plates 204, preventing the cutter 4 from cutting the bamboo branches. It also solves the problem of bamboo branches being scattered and not fully adhering to the guide ring 2. Furthermore, by increasing the friction between the guide ring 2 and the bamboo branches through the first limiting ring 301 and the protrusion 302, the friction is enhanced, improving the fixing effect of the rubber strip 306 on the bamboo branches. Simultaneously, the bamboo branches are lifted a second time, bringing them closer to a vertical position, reducing the amount of bamboo branches remaining on the main stem after cutting. This reduces the risk of relative sliding between bamboo pieces during transportation, preventing the main stem from being scratched by bamboo branches.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
