Description

Technical Field

[0001] This invention relates to the field of bamboo skewer cutting technology, and in particular to an adjustable bamboo skewer fixed-distance cutting device and method. Background Technology

[0002] The adjustable bamboo skewer cutting device is a specialized piece of equipment used for cutting bamboo skewers to a fixed length. Its core feature is the ability to adjust the cutting length as needed, allowing for equidistant cutting of bundles of bamboo skewers. It is widely used in bamboo skewer processing, disposable tableware, and barbecue skewer production.

[0003] Existing cutting devices require operators to manually bundle bamboo skewers with straps and move the bundled skewers to the designated cutting position before starting the device to complete the cutting. On one hand, the bundled bamboo skewers have inherent height differences and loose arrangement, and may contain impurities, leading to uneven force on the cutting blade during cutting. This can result in some skewers having crooked or rough cuts. On the other hand, manually bundling the skewers with straps is time-consuming and labor-intensive. Furthermore, relying solely on simple strap constraints during cutting can cause lateral movement and longitudinal shifting under blade impact, potentially leading to skewer breakage and reducing the finished product yield. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an adjustable bamboo skewer fixed-distance cutting device and method, so as to solve the problems that existing devices are prone to poor cut quality due to loose and uneven bamboo skewers and impurities, and are also prone to deviation and breakage of bamboo skewers during cutting due to unstable fixing, which reduces the qualified rate of finished products. In addition, manual fixing is time-consuming, labor-intensive and inefficient.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An adjustable bamboo skewer cutting device includes: a support frame and a cutting mechanism slidably mounted on the bottom rear side of the support frame. Multiple connecting frames are slidably mounted on the front side of the support frame. Each connecting frame has a cutting hole on its rear side. A limit plate is mounted on the top of each connecting frame via a cylinder. Connecting rods are symmetrically arranged on the rear side of the limit plates. The connecting rods are slidably connected to sliding holes symmetrically opened on the rear side of the connecting frames. Grooves are symmetrically opened on the bottom of each connecting frame. A strip-shaped groove plate is fixedly connected inside each groove. Multiple sliding grooves symmetrically opened on both sides of the strip-shaped groove plate each have a slider mounted via a spring. A toggle block is fixedly connected between every two symmetrical sliders. A toggle assembly is provided between the groove and the connecting rod for adjusting the position of the toggle block. Smoothing assemblies are symmetrically arranged on both sides of the limit plate for adjusting the state of the bamboo skewer substrate.

[0006] Optionally, the actuating assembly includes a rack and a screw. The rack is fixed to the bottom end of the connecting rod. The rack teeth are meshed with a gear. The gear is installed at the rear end of the screw. The screw is rotatably installed inside a groove. A movable plate is slidably connected to the outside of the screw via a collar. The bottom of the movable plate is slidably connected to the bottom mounting groove inside the groove via a protrusion. A contact block is symmetrically and slidably connected to the cavity inside the movable plate. The upper end of the contact block contacts and slides against the actuating block.

[0007] Optionally, the top and bottom surfaces of the actuating block are both designed as arc-shaped surfaces, and the top surface of the abutting block is designed as a wavy abutting surface. The wavy abutting surface of the abutting block is used to engage with the arc-shaped bottom surface of the actuating block.

[0008] Optionally, the front end of the connecting frame is symmetrically provided with oil chambers, and an adjustment component is provided between the oil chambers and the moving plate. The adjustment component is used to adjust the position of the abutment block.

[0009] Optionally, the adjusting assembly includes a second screw, which is rotatably connected to a connecting frame via a motor. A push post is slidably connected to the outer side of the second screw via a thread, and a push plate slides against the rear side of the push post. The push plate is connected to an oil chamber via a spring, and the ports symmetrically opened on the rear sidewall of the oil chamber are connected to the ports on both sides of the moving plate via flexible hoses.

[0010] Optionally, the smoothing component includes an arc-shaped plate and a fixed plate. The arc-shaped plate is fixedly connected to a limiting plate via a connecting block. The fixed plate is slidably connected to an arc-shaped groove on the outer side of the arc-shaped plate via a sliding column on one side. A connecting column is slidably connected to an arc-shaped hole on the outer side of the arc-shaped plate. One end of the connecting column is rotatably connected to the fixed plate via a motor. The other end of the connecting column is fixedly connected to a mounting bracket. A connecting seat is installed in the positioning groove on the inner side of the mounting bracket via an elastic telescopic rod. A kneading roller is rotatably connected to the inner side of the connecting seat. A second gear is fixedly connected to the outer side of the connecting column. A half-tooth ring is engaged with the lower tooth of the second gear. The half-tooth ring is fixedly connected to the outer side of the arc-shaped plate.

[0011] Optionally, the mounting bracket has positioning grooves on its inner front and rear arms and top. The length of the top positioning groove corresponds to the diameter of the arc plate, and the two side positioning grooves correspond to the arc plate.

[0012] Optionally, the bottom surface of the limiting plate is designed as an arc-shaped surface, and the lower limit position of the rubbing roller on the top inner side of the mounting frame is lower than the highest point of the arc-shaped surface at the bottom of the limiting plate.

[0013] Optionally, the center position of the arc-shaped plate corresponds to the center position of the arc-shaped surface at the bottom of the limiting plate.

[0014] Optionally, the method includes the following steps: S1: Adjust the agitation amplitude of the agitator block according to the bamboo skewers of different diameters. Drive the push column to move through the motor. The farther the push column is pushed, the higher the initial height of the contact block, and the higher the height the agitator block is lifted, thus the greater the agitation amplitude of the agitator block. S2: Place the bundled bamboo skewers at the bottom of the connecting frame, start the cylinder to drive the limit plate to move down, and drive the actuating component to move the contact block to lift the actuating block, so that the actuating block moves up to insert into the bundle of bamboo skewers for actuation. S3: As the rubbing roller moves down with the limiting plate, it contacts the surface of the bamboo skewer bundle. During the process of the mounting frame reciprocating in an arc shape driven by the smoothing component, the rubbing rollers on the inner bottom of the mounting frame and the two side arms together form a wrapping treatment space for the outside of the bamboo skewer bundle, rubbing the bamboo skewer bundle to prevent the bamboo skewer base material from arching. S4: After the limiting plate has finished pressing the bamboo bundle, it moves left and right along the support frame and forward to the designated position through the fixed-distance cutting mechanism. Its cutting blade passes through the cutting hole to cut the bamboo sticks to a fixed length, thus completing the cutting.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a toggle component and an adjustment component, the bamboo skewer is placed at the bottom of the connecting frame. The cylinder is activated to drive the limit plate to move down, thereby driving the rack to move down. Under the action of gear one and screw one, the moving plate is driven to slide horizontally. The contact block moves with the moving plate and smoothly lifts the toggle block, so that the toggle block moves the bamboo skewer substrate, making the bamboo skewer substrate neatly arranged and tightly bound, while shaking off internal impurities. When changing bamboo skewer substrates of different diameters, the motor drives screw two to rotate, driving the push column to push the push plate to inject oil into the moving plate, thereby raising the initial position of the contact block, and thus increasing the lifting height of the toggle block. The farther the distance the motor drives the push column to advance, the more oil is injected into the cavity of the moving plate, the higher the initial height of the contact block, the higher the height the toggle block is lifted, and the greater the toggle amplitude of the toggle block.

[0016] In the above solution, by setting up a smoothing component, during the downward movement of the limiting plate, the kneading roller, due to its lower limit position, contacts the surface of the bamboo skewer bundle first. The motor drives the connecting column to rotate, and the gear two meshes with the half-tooth ring, causing the connecting column to revolve along the arc-shaped hole. This drives the front and rear arms inside the mounting frame and the kneading roller at the top to rotate synchronously, forming a wrapping processing space to knead the bamboo skewer substrate in all directions. This achieves self-fixation of the bamboo skewer substrate externally, eliminating the need for manual pressing and reinforcement. At the same time, a stable constraint force is continuously applied to the bamboo skewer substrate during the cutting process, which helps to avoid problems such as jumping, shifting, and curling of the bamboo skewer substrate at the moment of cutting. This is beneficial to improving cutting accuracy and processing efficiency, and reducing manual labor intensity. Attached Figure Description

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figures 1 to 13As shown, an embodiment of the present invention provides an adjustable bamboo skewer cutting device, comprising: a support frame 1 and a cutting mechanism 2 slidably mounted on the bottom rear side of the support frame 1. Multiple connecting frames 3 are slidably mounted on the front side of the support frame 1. Each connecting frame 3 has a cutting hole 31 on its rear side. Each connecting frame 3 has a limit plate 4 mounted on its top end via a cylinder. Connecting rods are symmetrically arranged on the rear side of the limit plate 4, and are slidably connected to sliding holes symmetrically opened on the rear side of the connecting frame 3. Each connecting frame 3 has a groove 32 symmetrically opened at its bottom. A strip-shaped groove plate 5 is fixedly connected inside the groove 32. Multiple sliding grooves symmetrically opened on both sides of the strip-shaped groove plate 5 have sliders 6 mounted via springs. A toggle block 7 is fixedly connected between every two symmetrical sliders 6. A toggle assembly 8 is provided between the groove 32 and the connecting rod, and the toggle assembly 8 is used for toggle... The position of the moving block 7 is adjusted. Smoothing components 9 are symmetrically arranged on both sides of the limiting plate 4. The smoothing components 9 are used to adjust the state of the bamboo skewer substrate. The bamboo skewer substrate to be cut is neatly placed at the bottom of the connecting frame 3. The cylinder at the top of the connecting frame 3 is activated. The cylinder drives the limiting plate 4 to move downward. At this time, the connecting rod on the rear side of the limiting plate 4 slides down synchronously along the sliding hole of the connecting frame 3 to ensure that the limiting plate 4 moves smoothly and without tilting. When the limiting plate 4 moves down and presses against the upper surface of the bundled bamboo skewers, it realizes the limiting and fixing of the bamboo skewers. After pressing is completed, the fixed-distance cutting mechanism 2 moves along the support frame 1 and moves forward to the designated position. Its cutting blade passes through the cutting hole 31 to cut the limited bamboo skewer substrate to a fixed length. Multiple connecting frames 3 slide on the support frame 1 to adjust the spacing. In conjunction with the fixed-distance cutting mechanism 2, it is convenient to realize the cutting needs of bamboo skewer substrates of different lengths.

[0021] The actuating assembly 8 includes a rack 81 and a screw 83. The rack 81 is fixed to the bottom end of the connecting rod. The rack 81 is meshed with a gear 82. The gear 82 is installed at the rear end of the screw 83. The screw 83 is rotatably installed inside the groove 32. A movable plate 84 is slidably connected to the outside of the screw 83 via a collar. The bottom of the movable plate 84 is slidably connected to the bottom mounting groove inside the groove 32 via a protrusion. A contact block 85 is symmetrically and slidably connected to the cavity inside the movable plate 84. The upper end of the contact block 85 abuts and slides against the actuating block 7. When the cylinder is activated, the limiting plate 4 moves downward to prepare to press the bamboo skewer substrate. The downward movement of the limiting plate 4 causes the connecting rod to slide down along the sliding hole. Since the rack 81 is fixed to the bottom end of the connecting rod, the rack 81 also moves downward. The downward movement of the rack 81 causes the meshing gear 82 to rotate. The rotation of the gear 82 causes the screw 83 to rotate. Rotation of screw 83: Since the moving plate 84 is connected to screw 83 via a collar and is restricted by the protrusion and the bottom mounting groove inside groove 32, the rotation of screw 83 drives the moving plate 84 to move horizontally in a straight line. The horizontally moving moving plate 84 drives the abutment block 85 to move. The abutment block 85 moves upward and presses the agitator block 7. After being pushed upward, the agitator block 7 will overcome the tension of the spring, slide in the groove and move upward. At this time, the top of the agitator block 7 will extend into the bamboo skewer substrate, agitate and comb the bamboo skewer substrate, making the bamboo skewer substrate more uniform and reducing the deviation of the bamboo skewer substrate when cutting. This makes the entire bamboo skewer substrate more compact and strong, and at the same time, it is easy to shake off and discharge impurities such as bamboo chips, broken nodes, and burrs mixed inside the bamboo skewer substrate. While the above combing action is taking place, the limiting plate 4 continues to move downward and finally presses firmly on the surface of the combed bamboo skewer substrate.

[0022] The top and bottom surfaces of the actuating block 7 are both designed as arc-shaped contact surfaces, and the top surface of the contact block 85 is designed as a wavy contact surface. The wavy contact surface of the contact block 85 is used to engage with the arc-shaped contact surface at the bottom of the actuating block 7. Since the top of the contact block 85 is designed as a wavy contact surface, and the top and bottom of the actuating block 7 are both designed as arc-shaped contact surfaces, when the contact block 85 moves, the wavy contact surface of the contact block 85 will smoothly push up the actuating block 7, forcing the actuating block 7 to overcome the spring tension and move upward along the slide groove.

[0023] The front end of the connecting frame 3 has symmetrically opened oil chambers. An adjustment component 10 is provided between the oil chambers and the moving plate 84. The adjustment component 10 is used to adjust the position of the abutment block 85.

[0024] Adjustment component 10 includes screw 101, which is rotatably connected to connecting frame 3 via a motor. A push post 102 is threadedly slidably connected to the outer side of screw 101. A push plate 103 slides against the rear side of push post 102. Push plate 103 is connected to oil cavity via a spring. Symmetrically opened ports on the rear side wall of oil cavity are connected to the two side ports of moving plate 84 via flexible hoses. When processing with bamboo skewers of different diameters, the actuation range of the actuating block 7 needs to be adjusted. When the actuation range of the actuating block 7 needs to be increased, the motor drives screw 101 to rotate. Since push post 102 is threadedly connected to screw 101, the rotation of screw 101 drives the push post 102 to rotate. The column 102 moves, pushing the push plate 103. The push plate 103 applies pressure to the oil in the oil chamber. The oil flows out from the port of the oil chamber through the hose and is squeezed into the ports on both sides of the moving plate 84. The oil entering the moving plate 84 generates hydraulic thrust, pushing the abutment block 85 to slide upward, raising the initial height of the abutment block 85. At this time, when the abutment block 85 moves, the height of the actuating block 7 is raised synchronously. The farther the motor drives the push column 102 to advance, the more oil is injected into the cavity of the moving plate 84, the higher the initial height of the abutment block 85, and the higher the height of the actuating block 7, thus the greater the actuating amplitude of the actuating block 7.

[0025] The smoothing component 9 includes an arc-shaped plate 91 and a fixed plate 92. The arc-shaped plate 91 is fixedly connected to the limiting plate 4 via a connecting block. The fixed plate 92 is slidably connected to the arc-shaped groove on the outer side of the arc-shaped plate 91 via a sliding column. A connecting column 93 is slidably connected to the arc-shaped hole on the outer side of the arc-shaped plate 91. One end of the connecting column 93 is rotatably connected to the fixed plate 92 via a motor. The other end of the connecting column 93 is fixedly connected to a mounting bracket 94. A connecting seat is installed in the positioning groove on the inner side of the mounting bracket 94 via an elastic telescopic rod. 95. A kneading roller 96 is rotatably connected to the inner side of the connecting seat 95. A gear 2 97 is fixedly connected to the outer side of the connecting column 93. A semi-toothed ring 98 is engaged with the lower tooth of the gear 2 97. The semi-toothed ring 98 is fixedly connected to the outer side of the arc plate 91. During the process of the bamboo skewer substrate being pressed by the limiting plate 4, the motor of the smoothing component 9 is started. The motor drives the connecting column 93 to start rotating. Since the gear 2 97 is fixedly connected to the connecting column 93, and the gear 2 97 is engaged with the semi-toothed ring 98 fixed on the arc plate 91, the smoothing component 93 starts rotating. The meshing mechanism allows the rotation of the connecting column 93 to be converted into its own revolution along the arc-shaped trajectory of the arc-shaped hole. The revolution of the connecting column 93 drives the mounting frame 94 to slide along the same arc-shaped trajectory. At the same time, the sliding column on the fixing plate 92 also slides synchronously in the arc-shaped groove of the arc-shaped plate 91, providing stable guidance and support for the entire movement. The sliding of the mounting frame 94 drives the rubbing roller 96 installed inside the mounting frame 94 to move accordingly. Since the connecting seat 95 is installed in the positioning groove of the mounting frame 94 through an elastic telescopic rod, the rubbing roller 96 can easily maintain a constant pressure on the surface of the bamboo skewer bundle when it moves along the arc-shaped trajectory. This arc-shaped reciprocating motion allows the rubbing roller 96 to cover the entire outer surface of the bamboo skewer bundle, so as to roll and rub the outer surface of the bamboo skewer bundle evenly, thereby achieving the pressing and fixing of the bamboo skewer bundle without the need for manual pressing, sorting or re-reinforcing. At the same time, it helps to reduce problems such as bamboo skewers jumping, shifting, and curling up caused by the bamboo skewer bundle not being firmly fixed during the cutting process.

[0026] The mounting frame 94 has positioning grooves on its inner front and rear arms and top. The length of the top positioning groove corresponds to the diameter of the arc plate 91, and the positioning grooves on both sides correspond to the arc plate 91. When the mounting frame 94 swings back and forth in an arc, the inner front and rear arms and the rubbing roller 96 on the top of the mounting frame 94 together form a wrapping treatment space for the outside of the bamboo skewer bundle, so as to rub the bamboo skewer bundle in all directions.

[0027] The bottom surface of the limiting plate 4 is designed as an arc surface. The lower limit position of the rubbing roller 96 on the top inner side of the mounting bracket 94 is lower than the highest point of the arc surface at the bottom of the limiting plate 4, so that during the pressing process of the limiting plate 4, the rubbing roller 96 first contacts the bamboo skewer substrate, and then the arc surface of the limiting plate 4 presses the bamboo skewer substrate.

[0028] The center of the arc plate 91 corresponds to the center of the arc surface at the bottom of the limiting plate 4.

[0029] As one embodiment of the present invention, the method includes the following steps: S1: Adjust the agitation amplitude of the agitator 7 according to the bamboo skewers of different diameters. Drive the pusher 102 to move by the motor. The farther the pusher 102 is pushed, the higher the initial height of the contact block 85, and the higher the height of the agitator 7 is lifted, thus the greater the agitation amplitude of the agitator 7. S2: Place the bundled bamboo skewers at the bottom of the connecting frame 3, start the cylinder to drive the limit plate 4 to move down, and drive the actuating component 8 to move the contact block 85 to lift the actuating block 7, so that the actuating block 7 moves up to insert into the bundle of bamboo skewers for actuation. S3: As the limiting plate 4 moves down, the kneading roller 96 contacts the surface of the bamboo skewer bundle. During the process of the mounting frame 94 rotating in an arc shape driven by the smoothing component 9, the inner bottom of the mounting frame 94 and the kneading rollers 96 on both sides of the mounting frame 94 together form a wrapping processing space for the outside of the bamboo skewer bundle, kneading the bamboo skewer bundle to prevent the bamboo skewer base material from arching. S4: After the limiting plate 4 has finished pressing the bamboo bundle, it moves left and right along the support frame 1 and forward to the designated position through the fixed-distance cutting mechanism 2. Its cutting blade passes through the cutting hole 31 to cut the bamboo sticks that are limited to a fixed length, thus completing the cutting.

[0030] The working principle of the technical solution provided by this invention is as follows: During the use of this device, the operator neatly places the bamboo skewer substrate to be cut at the bottom of the connecting frame 3, activates the cylinder at the top of the connecting frame 3, and drives the limiting plate 4 to move downward. The downward movement of the limiting plate 4 causes the connecting rod to slide down along the sliding hole. At this time, the rack 81 fixed at the bottom of the connecting rod moves downward accordingly. The downward movement of the rack 81 engages with the driving gear 82 to rotate. The rotation of the gear 82 drives the screw 83 to rotate, thereby driving the moving plate 84 to slide horizontally within the groove 32. The horizontally moving moving plate 84 drives the... As the contact block 85 moves, the wavy contact surface at the top of the contact block 85 contacts the arc-shaped contact surface at the bottom of the agitator block 7. As the moving plate 84 moves, the contact block 85 smoothly pushes the agitator block 7 upward, causing the agitator block 7 to move upward against the spring tension, thereby agitating the bamboo skewer substrate. This makes the bamboo skewer substrate more uniform and reduces the skewers during cutting, making the entire bamboo skewer bundle tighter and stronger. It also facilitates the shaking off and expelling of impurities such as bamboo chips, broken sections, and burrs mixed inside the bamboo skewer substrate. When changing to bamboo skewer materials of different diameters, the agitation range of the agitator 7 needs to be adjusted. The motor drives the screw 101 to rotate, and the pusher 102 pushes the pusher plate 103 to move, so that the oil is injected into the moving plate 84 through the hose. The hydraulic thrust lifts the contact block 85 to a higher initial position. When the contact block 85 moves, the height of the agitator 7 will increase. The farther the motor drives the pusher 102 to advance, the more oil is injected into the cavity of the moving plate 84, the higher the initial height of the contact block 85, and the higher the height of the agitator 7, thereby expanding the agitation range of the agitator 7. When it is necessary to cut bamboo skewer substrates with smaller diameters, the amount of bamboo skewer substrates fixed will increase because the diameter of the bamboo skewer substrates becomes smaller. At this time, the agitation range of the agitator 7 needs to be greater. Since the lower limit position of the kneading roller 96 is lower than the highest point of the bottom arc surface of the limiting plate 4, the kneading roller 96 will first contact the surface of the bamboo skewer substrate as the limiting plate 4 moves down. The motor drives the connecting column 93 to rotate. Since the connecting column 93 is fixedly connected to the gear 2 97, and the gear 2 97 meshes with the half-tooth ring 98 fixed on the arc plate 91, the rotation of the connecting column 93 will be converted into its own revolution along the arc trajectory of the arc hole. The revolution of the connecting column 93 will drive the mounting frame 94 to slide along the same arc trajectory. At this time, when the mounting frame 94 performs arc reciprocating rotation, the inner front and rear arms of the mounting frame 94 and the kneading roller 96 at the top together form a wrapping processing space for the outside of the bamboo skewer bundle, so as to knead the bamboo skewer bundle in all directions, realize the pressing and fixing of the bamboo skewer bundle, without the need for manual pressing, sorting or reinforcing. At the same time, it is easy to reduce the problems of bamboo skewer jumping, shifting, and curling due to the bamboo skewer bundle not being fixed firmly during the cutting process. After the limiting plate 4 completes the pressing of the bamboo skewer substrate, the fixed-distance cutting mechanism 2 moves along the support frame 1 and advances to the designated position. Its cutting blade passes through the cutting hole 31 to cut the fixed-length bamboo skewer substrate. The spacing is adjusted by sliding multiple connecting frames 3 on the support frame 1. In conjunction with the fixed-distance cutting mechanism 2, it is easy to meet the cutting requirements of bamboo skewers of different lengths. After the cutting is completed, the fixed-distance cutting mechanism 2 retracts, the cylinder drives the limiting plate 4 to lift, the rack 81 rises and drives the gear 82 to reverse, the moving plate 84 resets, and the toggle block 7 falls under the action of the spring, ready for the next working cycle.
