Description

Technical Field

[0001] The invention belongs to the technical field of sunflower-bone broom processing, and in particular relates to a handle cutting device for sunflower-bone broom processing. Background Art

[0002] A sunflower-bone broom is made primarily from sunflower bones. Sunflower bones refer to the veins extracted from the leaves of sunflowers (usually referring to certain species of palms, such as the palmetto). These hard veins can be tied or fixed together to form a broom. The handle of a sunflower-bone broom is typically made from a round rod, made of materials including but not limited to metal, plastic, and bamboo.

[0003] Handle processing is a crucial step in the production of sunflower-bone brooms. This process typically involves cutting the handles to a specified length. In the prior art, handle cutting is typically performed using a cutting machine. However, existing cutting equipment can typically only process one handle at a time, resulting in low efficiency. While batch cutting equipment is available, such equipment requires individual positioning of each handle to be processed during a single process, and typically can only process handles of the same size, resulting in significant limitations. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a handle cutting device for processing sunflower-bone brooms, aiming to solve the problems raised in the above-mentioned background technology.

[0005] An embodiment of the present invention is implemented as follows: a handle cutting device for processing a sunflower-bone broom comprises a workbench, wherein one end of the workbench is provided with a plurality of first V-shaped placement seats equidistantly distributed along the width direction thereof, a corresponding number of second V-shaped placement seats are also provided at corresponding positions at the other end of the workbench, a limit baffle is provided on a side of the second V-shaped placement seat away from the first V-shaped placement seat, the limit baffle is slidably mounted on the workbench along the length direction of the workbench, and the workbench is further provided with an adjustment unit for driving the limit baffle to move; and further comprising: Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The swing arm ends up being rotated by the hook at twoer ends of the swing arm. The swing arm ends are rotated by the hook portion. The cutting module is arranged below one end of the workbench close to the first V-shaped placement seat and is used to cut the handle to be cut.

[0006] The adjusting unit includes an adjusting screw mounted on the end of the workbench, and a threaded hole matching the adjusting screw is provided in the workbench. One end of the adjusting screw is rotatably connected to the limit baffle, and a rotating wheel is installed on the other end of the adjusting screw.

[0007] A further technical solution is that the auxiliary positioning module includes a mounting column installed at the bottom of the connecting seat, a horizontal push rod is installed inside the mounting column for sliding along the length direction of the workbench, and two symmetrical pressure rods are provided at both ends of the mounting column along the length direction of the workbench, the pressure rods are slidably installed in the mounting column along the vertical direction, and the lower end of each pressure rod extends to the outside of the mounting column, and a first spring connected to the pressure rod is also provided inside the mounting column, and a V-shaped pressure block is provided at the bottom of each pressure rod, a first inclined surface is provided at the top of the pressure rod, and a second inclined surface matching the first inclined surface is provided at the end of the horizontal push rod; when not subject to external force, the elastic force of the first spring will cause the first inclined surface to fit the second inclined surface, and cause the horizontal push rod to be located in the middle position of the mounting column.

[0008] A further technical solution is that the cutting module includes a mounting plate slidably installed under the workbench in the vertical direction, and a cutting hole matching the mounting plate is provided on the workbench, and the outer contour of the cutting hole is the same as the outer contour of the mounting plate. The bottom of the workbench is also provided with a lifting module for driving the mounting plate to move in the vertical direction. A number of rotating shafts are equidistantly installed on the mounting plate, and the number of the rotating shafts is the same as the number of the first V-shaped placement seats. A saw blade is installed on each of the rotating shafts, and the rotating shafts are connected to each other through a pulley and belt mechanism. A driving motor is also provided at the bottom of the mounting plate, and the output end of the driving motor is connected to a rotating shaft through a pulley and belt mechanism.

[0009] According to a further technical solution, the lifting module includes a base plate installed below the workbench, and a second control member is provided on the base plate for driving the mounting plate to move in a vertical direction.

[0010] According to a further technical solution, the first control member and the second control member are both pneumatic telescopic rods.

[0011] According to a further technical solution, a protective unit for covering the cutting position of the handle to be cut is provided on the cutting hole. The protective unit is connected to the lifting plate and is pressed onto the workbench by moving downward synchronously with the lifting plate.

[0012] A further technical solution is that the protection unit includes a protective cover arranged directly above the cutting hole, and the protective cover is symmetrically provided with a number of avoidance holes on both sides along the length direction of the workbench, and two symmetrical sealing sponges are installed in each of the avoidance holes. A connecting column is slidably installed on the top of the protective cover in the vertical direction, and the connecting column is connected to the lifting plate through a fixing rod, and the lower part of the connecting column is also provided with a second spring connected to the top wall of the protective cover.

[0013] The present invention provides a handle cutting device for processing sunflower-bone brooms. During use, the operator first adjusts the position of the limit baffle through an adjustment unit so that when one end of the handle to be cut abuts the limit baffle, the position to be cut is exactly at the cutting module. Multiple handles to be cut can then be placed simultaneously on the first and second V-shaped placement seats (the first and second V-shaped placement seats, which are located on the same straight line, are used to place the two ends of the same handle, respectively). The first control member then drives the lifting plate downward, which, via a V-shaped connecting rod structure, drives the connecting seats to move downward synchronously. The connecting seats then drive the auxiliary positioning module to press fit onto the handle to be cut, thereby securing the handle. And in this process, when the diameters of the handles placed on each first V-shaped placement seat are different, the auxiliary positioning module corresponding to the handle with the larger diameter will first be pressed against it. At this time, the auxiliary positioning module will no longer continue to move downward, and the height position of the connecting seat corresponding to the auxiliary positioning module will no longer continue to drop. At this time, the V-shaped connecting rod structure connected to the connecting seat will react to the sliding seat connected to its end and push it to slide sideways. The V-shaped connecting rod structure adjacent to the V-shaped connecting rod structure will be affected and shrink the angle, thereby pushing the connecting seat connected to it to continue to move downward until all the auxiliary positioning modules are pressed against the corresponding handles, thus completing the positioning of all handles. Then the cutting module is controlled to cut the positioned handles, thus completing the entire handle cutting operation. The device can adaptively fix handles of different specifications and can cut multiple handles of different specifications at the same time. It has high working efficiency and good use effect.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0018] like Figures 1-4 As shown, a handle cutting device for processing a sunflower-bone broom provided by one embodiment of the present invention includes a workbench 1, wherein a plurality of first V-shaped placement seats 11 are evenly distributed along the width direction at one end of the workbench 1, and a corresponding number of second V-shaped placement seats 12 are also provided at corresponding positions at the other end of the workbench 1. A limit baffle 13 is provided on a side of the second V-shaped placement seat 12 away from the first V-shaped placement seat 11. The limit baffle 13 is slidably mounted on the workbench 1 along the length direction of the workbench 1, and the workbench 1 is also provided with an adjustment unit 2 for driving the limit baffle 13 to move; and further comprising: The main positioning module 3 includes a mounting frame 31 mounted on the workbench 1, a lifting plate 32 is slidably mounted on the mounting frame 31 in the vertical direction, and a first control member 33 is further provided on the mounting frame 31 for driving the lifting plate 32 to move, and a fixed seat 34 is fixedly provided at both ends of the bottom surface of the lifting plate 32 (along the width direction of the workbench 1), and a plurality of sliding seats 35 are equidistantly distributed between the two fixed seats 34, and each sliding seat 35 is slidably mounted on the lifting plate 32 along the width direction of the workbench 1; The fixed seat 34 and the sliding seat 35, as well as two adjacent sliding seats 35, are connected by a V-shaped connecting rod structure, and the number of V-shaped connecting rod structures is the same as the number of first V-shaped placement seats 11. The V-shaped connecting rod structure is composed of two mutually hinged connecting rods 36; the free ends of the two connecting rods 36 in each group of V-shaped connecting rod structures are respectively hinged to the fixed seat 34 or the sliding seat 35, and the hinged ends of the two connecting rods 36 are mounted on a connecting seat 37; the bottom of the connecting seat 37 is provided with an auxiliary positioning module 4 for pressing onto the handle to be cut; The cutting module 6 is arranged below one end of the workbench 1 close to the first V-shaped placement seat 11 and is used to cut the handle to be cut.

[0019] In the embodiment of the present invention, during use, the operator can first adjust the position of the limit baffle 13 through the adjustment unit 2 so that when one end of the handle to be cut abuts against the limit baffle 13, the position to be cut is exactly at the cutting module 6. Then, multiple handles to be cut can be placed on the first V-shaped placement seat 11 and the second V-shaped placement seat 12 at one time (the first V-shaped placement seat 11 and the second V-shaped placement seat 12 on the same straight line are respectively used to place the two ends of the same handle), and then the first control member 33 drives the lifting plate 32 to move downward. The lifting plate 32 can drive the various connecting seats 37 to move downward synchronously through the V-shaped connecting rod structure. The connecting seat 37 drives the auxiliary positioning module 4 to press onto the handle to be cut, thereby fixing the handle. During this process, when the handles placed on the first V-shaped placement seats 11 have different diameters, the auxiliary positioning module 4 corresponding to the handle with the larger diameter will first abut against it. At this time, the auxiliary positioning module 4 will no longer move downward, and the height position of the connecting seat 37 corresponding to the auxiliary positioning module 4 will no longer continue to decrease. At this time, the V-shaped connecting rod structure connected to the connecting seat 37 will react on the sliding seat 35 connected to its end and push it to slide sideways. The V-shaped connecting rod structure adjacent to the V-shaped connecting rod structure will be affected and shrink the angle, thereby pushing the connecting seat 37 connected to it to continue to move downward until all the auxiliary positioning modules 4 are abutted against the corresponding handles, that is, all the handles are positioned. Then, the cutting module 6 is controlled to cut the positioned handles, that is, the entire handle cutting operation is completed.

[0020] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the adjusting unit 2 includes an adjusting screw 21 installed at the end of the workbench 1 (the end away from the first V-shaped placement seat 11), and a threaded hole matching the adjusting screw 21 is also provided in the workbench 1, one end of the adjusting screw 21 is rotatably connected to the limit baffle 13, and the other end of the adjusting screw 21 is installed with a rotating wheel 22.

[0021] In an embodiment of the present invention, when the position of the limit baffle 13 is to be adjusted, the operator only needs to rotate the wheel 22. The wheel 22 can drive the adjusting screw 21 to rotate synchronously. By adjusting the screw 21 and the threaded hole, the limit baffle 13 can be driven to move linearly along the length direction of the workbench 1, thereby adjusting the position of the limit baffle 13 for cutting handles of different lengths.

[0022] As a preferred embodiment of the present invention, the first control member 33 can be a pneumatic telescopic rod, an electric telescopic rod or a hydraulic telescopic rod, the telescopic end of which is connected to the lifting plate 32. By controlling its extension and retraction, the lifting plate 32 can be driven to move linearly in the vertical direction.

[0023] like Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the auxiliary positioning module 4 includes a mounting column 41 installed at the bottom of the connecting seat 37, and a horizontal push rod 45 is slidably installed inside the mounting column 41 along the length direction of the workbench 1, and two symmetrical pressure rods 42 are provided at both ends of the mounting column 41 along the length direction of the workbench 1, and the pressure rods 42 are slidably installed in the mounting column 41 along the vertical direction, and the lower end of each pressure rod 42 extends to the outside of the mounting column 41, and the interior of the mounting column 41 is also provided with a first spring 44 connected to the pressure rod 42, and the bottom of each pressure rod 42 is provided with a V-shaped pressure block 43, the top of the pressure rod 42 is provided with a first inclined surface 421, and the end of the horizontal push rod 45 is provided with a second inclined surface 451 matching the first inclined surface 421; when no external force is applied, the elastic force of the first spring 44 will make the first inclined surface 421 fit into the second inclined surface 451, and make the horizontal push rod 45 located in the middle position of the mounting column 41.

[0024] In this embodiment of the present invention, in the initial state, the horizontal push rod 45 is located in the middle of the mounting post 41, and the second inclined surfaces 451 at its ends respectively mate with the first inclined surfaces 421 at the tops of the two pressure rods 42. As the connecting seat 37 drives the auxiliary positioning module 4 downward as a whole, the V-shaped pressure block 43 engages the handle to be cut, thereby pressing the handle together and preventing it from shaking during the cutting process. If the handle to be cut is a regular cylindrical shape, the two pressure rods 42 will simultaneously fix the handle, and the horizontal push rod 45 will not move. When the handle to be cut is an irregular cylinder (that is, there is a certain difference in the handle diameters corresponding to the positions where the two V-shaped pressure blocks 43 in the same mounting column 41 are pressed together, and the conventional positioning mechanism cannot stably fix the handle at this time), the part with a larger diameter will first contact and press against the corresponding V-shaped pressure block 43. At this time, the V-shaped pressure block 43 on the other side has not yet completely pressed the handle, and the mounting column 41 will continue to move downward. At this time, the pressure rod 42 on the fixed side will be relatively displaced with the mounting column 41, and the cooperation between the first inclined surface 421 and the second inclined surface 451 can push the horizontal push rod 45 to move to the side that has not yet been fixed. This side also pushes the pressure rod 42 on this side to move downward through the cooperation between the second inclined surface 451 and the first inclined surface 421 until the V-shaped pressure block 43 on this side also presses against the handle to be cut, thereby completing the fixation of the irregular handle (especially for handles made of bamboo poles).

[0025] like Figure 1 and Figure 6 As shown, as a preferred embodiment of the present invention, the cutting module 6 includes a mounting plate 63 slidably installed below the workbench 1 in the vertical direction, and a cutting hole 14 matching the mounting plate 63 is provided on the workbench 1, and the outer contour of the cutting hole 14 is the same as the outer contour of the mounting plate 63. The bottom of the workbench 1 is also provided with a lifting module for driving the mounting plate 63 to move in the vertical direction, and a plurality of rotating shafts 65 are equidistantly installed on the mounting plate 63. The number of the rotating shafts 65 is the same as the number of the first V-shaped placement seat 11. A saw blade 64 is installed on each of the rotating shafts 65, and the rotating shafts 65 are connected to each other through a pulley and belt mechanism. A driving motor 66 is also provided at the bottom of the mounting plate 63, and the output end of the driving motor 66 is connected to a rotating shaft 65 through a pulley and belt mechanism.

[0026] In the embodiment of the present invention, when in use, it is only necessary to start the drive motor 66, which drives the rotating shaft 65 connected thereto to rotate via a pulley and belt mechanism. The rotating shafts 65 also rotate synchronously via the pulley and belt mechanism, thereby driving the saw blade 64 to rotate. The mounting plate 63 is controlled to rise by the lifting module, thereby cutting the handle.

[0027] like Figure 6As shown, as a preferred embodiment of the present invention, the lifting module includes a base plate 61 installed below the workbench 1, and the base plate 61 is provided with a second control member 62 for driving the mounting plate 63 to move in the vertical direction.

[0028] In this embodiment of the present invention, the second control member 62 can also be a pneumatic telescopic rod, an electric telescopic rod, or a hydraulic telescopic rod, and the second control member 62 and the first control member 33 are the same device. The telescopic end of the second control member 62 is connected to the mounting plate 63, and the second control member 62 can be controlled to move the mounting plate 63 linearly in the vertical direction by controlling the telescopic end of the second control member 62.

[0029] like Figure 1 and Figure 5 As shown, as a preferred embodiment of the present invention, a protective unit 5 for covering the cutting position of the handle to be cut is further provided on the cutting hole 14, and the protective unit 5 is connected to the lifting plate 32 and is pressed onto the workbench 1 by following the lifting plate 32 in synchronous downward movement.

[0030] In an embodiment of the present invention, the protective unit 5 includes a protective cover 51 arranged directly above the cutting hole 14, and the protective cover 51 is symmetrically provided with a number of avoidance holes 55 on both sides along the length direction of the workbench 1, and each of the avoidance holes 55 is installed with two symmetrical blocking sponges 56. The top of the protective cover 51 is slidably installed with a connecting column 52 in the vertical direction. The connecting column 52 is connected to the lifting plate 32 through a fixing rod 53, and the lower part of the connecting column 52 is also provided with a second spring 54 connected to the top wall of the protective cover 51.

[0031] In the initial state, the protective cover 51 is at its upper limit position. The second spring 54 contracts under the weight of the protective cover 51. As the lifting plate 32 moves downward, the fixing rod 53 drives the connecting column 52 downward in tandem. The protective cover 51 also moves downward until it abuts the upper surface of the workbench 1. The protective cover 51 covers the handle where it will be cut, effectively preventing debris from splashing during cutting. The handle passes through the corresponding escape hole 55, and the sealing sponge 56 fits tightly against the handle, preventing cutting debris from splattering through the escape hole 55. If the protective cover 51 abuts the upper surface of the workbench 1 and the auxiliary positioning module 4 has not yet secured the handle (i.e., the lifting plate 32 will continue to move downward), the lifting plate 32, via the fixing rod 53, can drive the connecting column 52 downward independently, stretching the second spring 54. The elastic restoring force of the second spring 54 stabilizes the protective cover 51 on the workbench 1.

[0032] Working principle: During use, the operator can first adjust the position of the limit baffle 13 through the adjustment unit 2 so that when one end of the handle to be cut abuts the limit baffle 13, the position to be cut is exactly at the cutting module 6. Then, multiple handles to be cut can be placed on the first V-shaped placement seat 11 and the second V-shaped placement seat 12 at one time (the first V-shaped placement seat 11 and the second V-shaped placement seat 12 on the same straight line are respectively used to place the two ends of the same handle). Then, the first control member 33 drives the lifting plate 32 to move downward. The lifting plate 32 can drive the various connecting seats 37 to move downward synchronously through the V-shaped connecting rod structure. The connecting seat 37 drives the auxiliary positioning module 4 to press onto the handle to be cut, thereby fixing the handle. During this process, when the handles placed on the first V-shaped placement seats 11 have different diameters, the auxiliary positioning module 4 corresponding to the handle with the larger diameter will first abut against it. At this time, the auxiliary positioning module 4 will no longer move downward, and the height position of the connecting seat 37 corresponding to the auxiliary positioning module 4 will no longer continue to decrease. At this time, the V-shaped connecting rod structure connected to the connecting seat 37 will react on the sliding seat 35 connected to its end, pushing it to slide sideways. The V-shaped connecting rod structure adjacent to the V-shaped connecting rod structure will be affected and shrink its angle, thereby pushing the connecting seat 37 connected to it to continue moving downward until all auxiliary positioning modules 4 are abutted against the corresponding handles, thus completing the positioning of all handles. In addition, as the connecting seat 37 drives the auxiliary positioning modules 4 to move downward as a whole, the V-shaped pressing block 43 will be stuck to the handle to be cut, thereby pressing the handle to prevent it from shaking during the cutting process. If the handle to be cut is a regular cylindrical shape, the two pressing rods 42 will simultaneously fix the handle, and the horizontal push rod 45 will not move. When the handle to be cut is an irregular cylinder (that is, there is a certain difference in the handle diameters corresponding to the positions where the two V-shaped pressure blocks 43 in the same mounting column 41 are pressed together, and the conventional positioning mechanism cannot stably fix the handle at this time), the part with a larger diameter will first contact and press against the corresponding V-shaped pressure block 43. At this time, the V-shaped pressure block 43 on the other side has not yet completely pressed the handle, and the mounting column 41 will continue to move downward. At this time, the pressure rod 42 on the fixed side will be relatively displaced with the mounting column 41, and the cooperation between the first inclined surface 421 and the second inclined surface 451 can push the horizontal push rod 45 to move to the side that has not yet been fixed. This side also pushes the pressure rod 42 on this side to move downward through the cooperation between the second inclined surface 451 and the first inclined surface 421 until the V-shaped pressure block 43 on this side also presses against the handle to be cut, thereby completing the fixation of the irregular handle (especially for handles made of bamboo poles). At the same time, the lifting plate 32 can also drive the connecting column 52 to move downward synchronously through the fixing rod 53. At this time, the protective cover 51 will also move downward synchronously until it is close to the upper surface of the workbench 1. The protective cover 51 will cover the position of the handle to be cut, which can effectively prevent the debris generated during cutting from splashing.The handle will pass through the corresponding avoidance hole 55, and the sealing sponge 56 will fit tightly against the handle, preventing cutting debris from splashing out of the avoidance hole 55. The drive motor 66 is then activated, and the drive motor 66 drives the connected shaft 65 to rotate via a pulley and belt mechanism. The shafts 65 also rotate synchronously via the pulley and belt mechanism, thereby driving the saw blade 64 to rotate. The second control member 62 drives the mounting plate 63 upward, thereby cutting the positioned handle, completing the handle cutting operation.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
