Description

Technical Field

[0001] The present invention belongs to the technical field of processing of brooms made of palm ribs, and particularly relates to a handle cutting device for processing brooms made of palm ribs. Background Art

[0002] A broom made of palm ribs is a broom that uses palm ribs as the main production material. Palm ribs refer to the vein parts extracted from the leaves of palms (usually certain species in the Palmae family, such as Chinese fan palms). These hard veins can be bundled or fixed together to make brooms. The handles of brooms made of palm ribs are usually made of round rods, and the specific materials include but are not limited to metals, plastics, and bamboo.

[0003] Handle processing is an important process in the production of brooms made of palm ribs. During the handle processing of brooms made of palm ribs, cutting of the handle is usually involved to process it into a specified length. In the prior art, handle cutting is usually carried out using a cutting machine. However, the existing cutting equipment can usually only process one handle at a time, and its working efficiency is low. There are also batch cutting devices, but such devices need to position each handle to be processed separately during one processing process, and usually can only process handles of the same size specification during one processing process, with many limitations in use.

Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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 used to limit the present invention.

[0024] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0025] As Figures 1-4 shown, a handle cutting device for processing sunflower bone brooms provided by an embodiment of the present invention includes a workbench 1. A plurality of first V-shaped placement seats 11 are equidistantly distributed along the width direction at one end of the workbench 1. At the corresponding position at the other end of the workbench 1, there are also provided a corresponding number of second V-shaped placement seats 12. A limit baffle 13 is provided on the 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 an adjustment unit 2 for driving the limit baffle 13 to move is also provided on the workbench 1; further included are:

[0026] The main positioning module 3, the main positioning module 3 includes a mounting frame 31 installed on the workbench 1, a lifting plate 32 is slidably installed on the mounting frame 31 in the vertical direction, and a first control member 33 for driving the lifting plate 32 to move is further provided on the mounting frame 31. Fixed seats 34 are fixedly provided at both ends of the bottom surface of the lifting plate 32 (along the width direction of the workbench 1). A plurality of sliding seats 35 are equidistantly distributed between the two fixed seats 34, and each sliding seat 35 is slidably installed on the lifting plate 32 along the width direction of the workbench 1; between the fixed seat 34 and the sliding seat 35, and between 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 the first V-shaped placing seats 11. The V-shaped connecting rod structure is composed of two connecting rods 36 hinged to each other; 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 installed on a connecting seat 37; an auxiliary positioning module 4 for pressing against the handle to be cut is provided at the bottom of the connecting seat 37;

[0027] The cutting module 6 is arranged below one end of the workbench 1 close to the first V-shaped placing seat 11 for cutting the handle to be cut.

[0028] In the embodiment of the present invention, in use, the operator can first adjust the position of the limit baffle 13 through the adjusting unit 2 so that when one end of the handle to be cut abuts against the limit baffle 13, its cutting position is exactly at the cutting module 6. Then, multiple handles to be cut can be placed on the first V-shaped placing seats 11 and the second V-shaped placing seats 12 respectively at one time (the first V-shaped placing seats 11 and the second V-shaped placing seats 12 on the same straight line are respectively used to place both 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 each connecting seat 37 to move downward synchronously through the V-shaped connecting rod structure. The connecting seat 37 drives the auxiliary positioning module 4 to press against the handle to be cut, so as to realize the fixation of the handle. And in this process, when the diameters of the handles placed on each first V-shaped placing seat 11 are different, the auxiliary positioning module 4 corresponding to the handle with a larger diameter will first abut against it. At this time, this auxiliary positioning module 4 will no longer continue to move downward, and the height position of the connecting seat 37 corresponding to this auxiliary positioning module 4 will no longer continue to drop. At this time, the V-shaped connecting rod structure connected to this connecting seat 37 will react on the sliding seat 35 connected to its end and push it to slide laterally. The V-shaped connecting rod structure adjacent to this V-shaped connecting rod structure will be affected and contract the included angle, so as to push the connecting seat 37 connected to it to continue to move downward until all the auxiliary positioning modules 4 abut against the corresponding handles, that is, the positioning of all the handles is completed. Then, control the cutting module 6 to cut the positioned handle, that is, complete the entire handle cutting operation.

[0029] As Figure 1 and Figure 2 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 placing seat 11), and a threaded hole matching the adjusting screw 21 is also formed in the workbench 1. One end of the adjusting screw 21 is rotatably connected to the limit baffle 13, and a runner 22 is installed at the other end of the adjusting screw 21.

[0030] In the embodiment of the present invention, when the position of the limit baffle 13 needs to be adjusted, the operator only needs to rotate the runner 22. The runner 22 can drive the adjusting screw 21 to rotate synchronously. Through the cooperation of the adjusting screw 21 and the threaded hole, the limit baffle 13 can be driven to linearly move along the length direction of the workbench 1, so as to adjust the position of the limit baffle 13 for cutting handles of different lengths.

[0031] As a preferred embodiment of the present invention, the first control member 33 can be a pneumatic expansion rod, an electric expansion rod or a hydraulic expansion rod, and its telescopic end is connected to the lifting plate 32. By controlling its telescopic movement, the lifting plate 32 can be driven to linearly move in the vertical direction.

[0032] As Figure 3 and Figure 4 shown, as a preferred embodiment of the present invention, the auxiliary positioning module 4 includes a mounting post 41 installed at the bottom of the connecting seat 37. A cross push rod 45 is slidably installed inside the mounting post 41 along the length direction of the workbench 1. Two symmetric pressure rods 42 are further arranged at both ends of the mounting post 41 along the length direction of the workbench 1. The pressure rods 42 are slidably installed in the mounting post 41 in the vertical direction, and the lower ends of the pressure rods 42 all extend to the outside of the mounting post 41. A first spring 44 connected to the pressure rods 42 is further arranged inside the mounting post 41. V-shaped pressing blocks 43 are arranged at the bottoms of the pressure rods 42. A first inclined surface 421 is arranged at the top of the pressure rod 42, and a second inclined surface 451 matching the first inclined surface 421 is arranged at the end of the cross push rod 45; when no external force acts, the elastic force of the first spring 44 will make the first inclined surface 421 fit with the second inclined surface 451, and make the cross push rod 45 located at the middle position of the mounting post 41.

[0033] In the embodiment of the present invention, in the initial state, the horizontal push rod 45 is located in the middle of the mounting column 41, and the second inclined surfaces 451 at both ends thereof are respectively in contact 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 to move downward as a whole, the V-shaped pressure block 43 will be stuck on the handle to be cut, thereby pressing the handle to prevent it from shaking during the cutting process. When the handle to be cut is a regular cylindrical shape, the two pressure rods 42 will fix the handle at the same time, 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 pressing 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 pressing block 43. At this time, the V-shaped pressing 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 pressing rod 42 on the fixed side will be relatively displaced with the mounting column 41, and through the cooperation of the first inclined surface 421 and the second inclined surface 451, the horizontal push rod 45 can be pushed to move to the side that has not yet been fixed. This side also pushes the pressing rod 42 on this side to move downward through the cooperation of the second inclined surface 451 and the first inclined surface 421, until the V-shaped pressing block 43 on this side also presses against the handle to be cut, thereby completing the fixation of the irregular handle (especially for the handle made of bamboo poles).

[0034] 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 opened 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, and 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, and the number of the rotating shafts 65 is the same as the number of the first V-shaped placement seat 11, and each of the rotating shafts 65 is installed with a saw blade 64, and each of the rotating shafts 65 is connected to each other through a pulley and belt mechanism, and 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.

[0035] In the embodiment of the present invention, when in use, it is only necessary to start the driving motor 66, which drives the rotating shaft 65 connected thereto to rotate through the pulley and belt mechanism, and the rotating shafts 65 also rotate synchronously through the pulley and belt mechanism, thereby driving the saw blade 64 to rotate. The mounting plate 63 is controlled to rise through the lifting module, so as to cut the handle.

[0036] like Figure 6As shown, as a preferred embodiment of the present invention, the lifting module includes a bottom plate 61 installed below the workbench 1, and a second control member 62 for driving the mounting plate 63 to move in the vertical direction is provided on the bottom plate 61.

[0037] In an 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 selected from the same type of device. Its telescopic end is connected to the mounting plate 63, and by controlling its telescopic movement, the mounting plate 63 can be driven to linearly move in the vertical direction.

[0038] As Figure 1 and Figure 5 shown, as a preferred embodiment of the present invention, a protection unit 5 for covering the cutting position of the handle to be cut is further provided on the cutting hole 14. The protection unit 5 is connected to the lifting plate 32 and is pressed onto the workbench 1 by moving downward synchronously with the lifting plate 32.

[0039] In an embodiment of the present invention, the protection unit 5 includes a protective cover 51 provided directly above the cutting hole 14. A plurality of avoidance holes 55 are symmetrically opened on both sides of the protective cover 51 along the length direction of the workbench 1, and two symmetrically arranged plugging sponges 56 are installed in each of the avoidance holes 55. A connecting column 52 is slidably installed on the top of the protective cover 51 in the vertical direction. The connecting column 52 is connected to the lifting plate 32 through a fixing rod 53, and a second spring 54 connected to the top wall of the protective cover 51 is further sleeved on the lower part of the connecting column 52.

[0040] In the initial state, the protective cover 51 is located at the upper limit position. At this time, the second spring 54 contracts under the action of the gravity of the protective cover 51. As the lifting plate 32 moves downward, the fixing rod 53 can drive the connecting column 52 to move downward synchronously. At this time, the protective cover 51 will also move downward synchronously until it abuts against the upper surface of the workbench 1. The protective cover 51 will cover the cutting position of the handle, effectively preventing the chips generated during cutting from splashing. And the handle will pass through the avoidance holes 55 at the corresponding positions, and the plugging sponges 56 will closely fit with the handle to prevent the chips during cutting from splashing out of the avoidance holes 55 to the outside. And if the protective cover 51 abuts against the upper surface of the workbench 1 and the auxiliary positioning module 4 has not fixed the handle yet (that is, the lifting plate 32 will still move downward), then at this time, the lifting plate 32 can drive the connecting column 52 to move downward alone through the fixing rod 53 and stretch the second spring 54. Through the elastic restoring force of the second spring 54, the protective cover 51 can be placed more stably on the workbench 1.

[0041] 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 against the limit baffle 13, its 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 respectively 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 both ends of the same handle). Then, the lifting plate 32 is driven by the first control member 33 to move downward. The lifting plate 32 can drive each connecting seat 37 to move downward synchronously through the V-shaped connecting rod structure. The connecting seat 37 drives the auxiliary positioning module 4 to press against the handle to be cut, thereby realizing the fixation of the handle. And during this process, when the diameters of the handles placed on each first V-shaped placement seat 11 are different, the auxiliary positioning module 4 corresponding to the handle with a larger diameter will first abut against it. At this time, this auxiliary positioning module 4 will no longer continue to move downward, and the height position of the connecting seat 37 corresponding to this auxiliary positioning module 4 will no longer continue to drop. At this time, the V-shaped connecting rod structure connected to this connecting seat 37 will act on the sliding seat 35 connected to its end and push it to slide laterally. The V-shaped connecting rod structure adjacent to this V-shaped connecting rod structure will be affected and contract the included angle, thereby pushing the connecting seat 37 connected to it to continue to move downward until all the auxiliary positioning modules 4 abut against the corresponding handles, that is, the positioning of all the handles is completed. In addition, during the process of the connecting seat 37 driving the auxiliary positioning module 4 to move downward as a whole, the V-shaped pressing block 43 will catch on the handle to be cut, thereby pressing the handle to prevent it from shaking during the cutting process. When the handle to be cut is a regular cylindrical shape, the two pressing rods 42 will fix the handle at the same time, and at this time the cross push rod 45 does not displace. When the handle to be cut is an irregular cylinder (that is, there is a certain difference in the diameters of the handles corresponding to the positions where the two V-shaped pressing blocks 43 in the same mounting column 41 are pressed. At this time, the conventional positioning mechanism cannot stably fix the handle), the larger diameter part will first contact and abut against the corresponding V-shaped pressing block 43. At this time, the V-shaped pressing block 43 on the other side has not completely abutted against the handle. The mounting column 41 will continue to move downward. At this time, the pressing rod 42 on the fixed side will have a relative displacement with the mounting column 41. Through the cooperation of the first inclined surface 421 and the second inclined surface 451, the cross push rod 45 can be pushed to move toward the side that has not been fixed. On this side, the pressing rod 42 on this side is also pushed to move downward through the cooperation of the second inclined surface 451 and the first inclined surface 421 until the V-shaped pressing block 43 on this side also abuts against the handle to be cut, and the fixation of the irregular handle (especially for the handle made of bamboo pole) can be completed. At the same time, the lifting plate 32 can also drive the connecting column 52 to move downward synchronously through the fixed rod 53. At this time, the protective cover 51 will also move downward synchronously until it abuts against the upper surface of the workbench 1. The protective cover 51 will cover the position to be cut of the handle, which can effectively prevent the chips generated during cutting from splashing.The handle will pass through the avoidance hole 55 at the corresponding position, and the sealing sponge 56 will closely fit with the handle to prevent the debris during cutting from splashing out through the avoidance hole 55. Then, the driving motor 66 is started. The driving motor 66 drives the rotating shaft 65 connected to it to rotate through the belt pulley mechanism. The rotating shafts 65 are also synchronously rotated through the belt pulley mechanism, so as to drive the saw blade 64 to rotate. The mounting plate 63 is driven to move upward by the second control member 62, so as to cut the positioned handle, that is, the entire handle cutting operation is completed.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
