Description

Technical Field

[0001] This invention relates to the field of paper tube processing equipment, specifically to an automatic length adjustment and control device for a paper tube cutting machine. Background Technology

[0002] A paper tube cutter is a specialized device that cuts finished paper tubes of different specifications and lengths into the required dimensions. Common paper tube cutters on the market typically place the paper tube on two initial support rollers, adjust the stops, and turn on the machine. Then, the initial power roller, carrying the drive motor, is lowered by a cylinder and presses down onto the paper tube, causing it to rotate. Immediately afterward, another cylinder lifts the entire assembly, which contains the cutting motor and a high-speed rotating saw blade. The high-speed rotating saw blade contacts the paper tube and cuts it in one revolution, completing the cutting of a single paper tube.

[0003] Existing paper tube cutting machines require manual adjustment of the baffle position during paper tube cutting, followed by manual pushing of the paper tube to contact the baffle. After cutting, the cut paper tube is manually removed, and the original paper tube must be pushed back to contact the baffle for the next cutting operation. The entire process involves a high degree of manual involvement, is labor-intensive, is greatly affected by human limitations, and significantly reduces efficiency. Therefore, an automatic length adjustment control device for paper tube cutting machines is proposed. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides an automatic length adjustment control device for a paper tube cutting machine.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an automatic length adjustment control device for a paper tube cutting machine, comprising a main body, a protective cover installed on the main body, a pressing component at the bottom end of the protective cover, a cutting component at the bottom end of the pressing component, a conveying mechanism on one side of the protective cover, and a limiting mechanism on the other side of the protective cover, a lifting mechanism at the bottom end of the limiting mechanism, a receiving mechanism on one side of the limiting mechanism, and a transfer mechanism connected to the bottom end of the receiving mechanism.

[0006] Specifically, the conveying mechanism includes a first pallet, and two first pallets are provided at the top of the main body. The first pallets are fixedly connected to the main body at an inclined angle. The two first pallets are symmetrically arranged. Multiple first rollers are rotatably connected to the first pallets, and one end of the first rollers extends into the interior of the protective cover.

[0007] Specifically, the conveying mechanism further includes a first servo motor, which is located between the two first pallets. A first lead screw is connected to the motor shaft of the first servo motor via a coupling. The first lead screw is rotatably connected to the top of the main body, and one end of the first lead screw extends into the interior of the protective cover. A first track is provided on each side of the first lead screw, and the first tracks are laid symmetrically on the main body. A slider is slidably connected between the two first tracks, and the slider is threadedly connected to the first lead screw. The first servo motor drives the slider to move along the first track through the first lead screw.

[0008] Specifically, the conveying mechanism also includes a stop bar. Two symmetrical stop bars are rotatably connected to the slider. The stop bar is L-shaped and a return torsion spring is wound around it. The return torsion spring drives the stop bar to automatically return to a vertical angle. A first protrusion is fixedly connected to the stop bar, and a second protrusion is fixedly connected to the slider. The second protrusion limits the first protrusion, and the stop bar rotates in one direction.

[0009] Specifically, the limiting mechanism includes a second support plate. Two symmetrically arranged second support plates are fixedly connected to the top of the other end of the main body. Multiple second rollers are rotatably connected to the second support plates. A second servo motor is installed at the top of the main body. A second lead screw is connected to the motor shaft of the second servo motor through a coupling. The second lead screw is rotatably connected to the main body. A second track is provided on each side of the second lead screw. A stop block is slidably connected to the second track. The stop block and the second lead screw are threaded together. A baffle is rotatably connected to the end of the stop block facing the protective cover. The second servo motor drives the stop block to move along the second track through the second lead screw.

[0010] Specifically, the lifting mechanism includes a first cylinder, and multiple first cylinders are provided between the two second pallets. The first cylinders are mounted on the main body, and an arc-shaped lifting plate is fixedly connected to the top of the first cylinder.

[0011] Specifically, the receiving mechanism includes a conveying plate, and a conveying plate is provided on one side of the second pallet. Two connecting parts are rotatably connected to the bottom end of the conveying plate. The connecting parts are welded together with the main body. A second cylinder is installed between the main body and the conveying plate. The second cylinder drives the conveying plate to rotate around the connecting parts. Folded edges are respectively bent and connected on both sides of the top end of the conveying plate.

[0012] Specifically, the transfer mechanism includes a limiting sleeve, a plurality of limiting sleeves are fixedly connected to the bottom end of the conveying plate, a telescopic sliding plate is slidably connected to the limiting sleeve, a reinforcing rod and a linkage rod are fixedly connected between the plurality of telescopic sliding plates, a scraper plate is fixedly connected to the end of the reinforcing rod, and a third cylinder is installed between the linkage rod and the bottom end of the conveying plate.

[0013] The beneficial effects of this invention are:

[0014] (1) The paper tube cutting machine length automatic adjustment control device of the present invention facilitates the pushing of raw materials to the contact block by the setting of the conveying mechanism. After the cutting is completed, the cut paper tube is conveniently pushed to the top of the lifting mechanism for the lifting mechanism to lift and transfer the cut paper tube. First, the raw material is placed on two first trays. At this time, the first roller supports the raw material. The first servo motor is started and drives the first screw to rotate. The first screw drives the slider to move along the first track direction. Then the abutment rod abuts one end of the raw material. Under the limit of the first and second protrusions, the abutment rod only has the function of unidirectional rotation. The abutment rod pushes the raw material to slide on the first roller at a vertical angle until the other end of the raw material contacts the baffle. Then the pressing component contacts the raw material and drives it to rotate. The cutting component contacts the raw material to cut. When the abutment rod with unidirectional rotation effect encounters the raw material that was put in in advance during the reset, the abutment rod can automatically fold after contact and stop pushing the raw material. After the reset is completed, it automatically pops out under the action of the reset torsion spring to play the role of pushing the material.

[0015] (2) The automatic length adjustment control device for a paper tube cutting machine described in this invention can automatically adjust the position of the stop block by setting a limit mechanism and automatically preset the length of the paper tube to be cut. When processing, the position of the stop block needs to be preset in advance according to the requirements. Then the second servo motor is started. The second servo motor drives the stop block to move along the second track through the second screw. When the predetermined position is adjusted, the conveying mechanism pushes one end of the raw material to contact the baffle. After the cutting is completed, the first servo motor and the second servo motor rotate synchronously in the same direction. The stop block retracts and the slider moves forward, so as to facilitate the cutting of the paper tube to the top of the lifting plate.

[0016] (3) The paper tube cutting machine length automatic adjustment control device of the present invention facilitates the lifting of the paper tube height by setting the lifting mechanism, so that the transfer mechanism can abut the material to the receiving mechanism and automatically transfer the cut paper tube out, avoiding manual material handling, reducing human involvement, reducing labor intensity, and improving processing efficiency; then the second cylinder moves to adjust the angle of the conveying plate, the third cylinder extends, and drives multiple telescopic sliding plates to slide through the linkage rod. The telescopic sliding plates drive the scraper plate to move to the bottom of the paper tube. Then the second cylinder retracts to reset the angle of the conveying plate, and the scraper plate scrapes the paper tube to the conveying plate. Then, under the action of gravity, it rolls to the finished product area. Then the scraper plate and the lifting plate are reset to the original distance to avoid blocking the movement of the stop block. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-9 As shown, the automatic length adjustment control device for a paper tube cutting machine of the present invention includes a main body 1, a protective cover 2 installed on the main body 1, a pressing component 3 at the bottom end of the protective cover 2, a cutting component 4 at the bottom end of the pressing component 3, a conveying mechanism 5 on one side of the protective cover 2, and a limiting mechanism 6 on the other side of the protective cover 2. A lifting mechanism 7 is provided at the bottom end of the limiting mechanism 6, a receiving mechanism 8 is provided on one side of the limiting mechanism 6, and a transfer mechanism 9 is connected to the bottom end of the receiving mechanism 8.

[0030] Specifically, the conveying mechanism 5 includes a first pallet 51. Two first pallets 51 are provided at the top of the main body 1. The first pallets 51 are fixedly connected to the main body 1 at an inclined angle. The two first pallets 51 are symmetrically arranged. Multiple first rollers 52 are rotatably connected to the first pallets 51. One end of the first rollers 52 extends into the interior of the protective cover 2.

[0031] Specifically, the conveying mechanism 5 further includes a first servo motor 54, which is located between the two first pallets 51. A first lead screw 53 is connected to the motor shaft of the first servo motor 54 via a coupling. The first lead screw 53 is rotatably connected to the top of the main body 1, and one end of the first lead screw 53 extends into the interior of the protective cover 2. A first track 55 is provided on each side of the first lead screw 53. The first tracks 55 are laid symmetrically on the main body 1. A slider 56 is slidably connected between the two first tracks 55. The slider 56 is threadedly connected to the first lead screw 53. The first servo motor 54 drives the slider 56 to move along the first track 55 through the first lead screw 53.

[0032] Specifically, the conveying mechanism 5 further includes a stop bar 57. Two symmetrical stop bars 57 are rotatably connected to the slider 56. The stop bars 57 are L-shaped, and a return torsion spring 58 is wound around each stop bar 57. The return torsion spring 58 drives the stop bar 57 to automatically return to a vertical angle. A first protrusion 59 is fixedly connected to the stop bar 57, and a second protrusion 591 is fixedly connected to the slider 56. The second protrusion 591 limits the first protrusion 59. The stop bar 57 rotates in one direction. First, the raw material is placed onto the two first pallets 51. At this time, the first roller 52 supports the raw material. The first servo motor 54 is started, driving the first lead screw 53 to rotate. A lead screw 53 drives the slider 56 to move along the first track 55. Then, the abutment rod 57 abuts against one end of the raw material. Under the limitation of the first protrusion 59 and the second protrusion 591, the abutment rod 57 only has a unidirectional rotation function. The abutment rod 57 pushes the raw material vertically to slide on the first roller 52 until the other end of the raw material contacts the baffle 66. Then, the pressing assembly 3 contacts the raw material and drives it to rotate. The cutting assembly 4 contacts the raw material to cut it. When the abutment rod 57 with a unidirectional rotation effect encounters the pre-placed raw material during reset, it can automatically fold after contact and stop pushing the raw material. After reset, it automatically pops out under the action of the reset torsion spring 58 to play the role of pushing the material.

[0033] Specifically, the limiting mechanism 6 includes a second support plate 61. Two symmetrically arranged second support plates 61 are fixedly connected to the top of the other end of the main body 1. Multiple second support rollers 62 are rotatably connected to the second support plates 61. A second servo motor 67 is installed at the top of the main body 1. A second lead screw 64 is connected to the motor shaft of the second servo motor 67 via a coupling. The second lead screw 64 is rotatably connected to the main body 1. A second track 63 is provided on each side of the second lead screw 64. A stop block 65 is slidably connected to the second track 63. The stop block 65 and the second lead screw 64 are threaded together. A baffle 66 is rotatably connected to the end of the stop block 65 facing the protective cover 2. The second servo motor 67 drives the stop block 65 to move along the second track 63 via the second lead screw 64. During processing, the position of the stop block 65 needs to be preset according to the requirements. Then, the second servo motor 67 is started. The second servo motor 67 drives the stop block 65 to move along the second track 63 via the second lead screw 64. When the predetermined position is reached, the conveying mechanism 5 pushes one end of the raw material to contact the baffle 66. After cutting, the first servo motor 54 and the second servo motor 67 rotate synchronously in the same direction. The stop block 65 retracts while the slider 56 pushes forward, thereby facilitating the movement of the cut paper tube to the top of the lifting plate 71.

[0034] Specifically, the lifting mechanism 7 includes a first cylinder 72, and multiple first cylinders 72 are provided between the two second pallets 61. The first cylinders 72 are mounted on the main body 1, and an arc-shaped lifting plate 71 is fixedly connected to the top of the first cylinder 72. After the paper tube position is transferred, the first cylinder 72 is activated, and the first cylinder 72 raises the height of the lifting plate 71, thereby raising the paper tube to a suitable height to facilitate subsequent material transfer operations.

[0035] Specifically, the receiving mechanism 8 includes a conveying plate 81. The conveying plate 81 is provided on one side of the second pallet 61. Two connecting parts 82 are rotatably connected to the bottom end of the conveying plate 81. The connecting parts 82 are welded together with the main body 1. A second cylinder 83 is installed between the main body 1 and the conveying plate 81. The second cylinder 83 drives the conveying plate 81 to rotate around the connecting parts 82. Folded edges 84 are bent and connected to both sides of the top end of the conveying plate 81.

[0036] Specifically, the transfer mechanism 9 includes a limiting sleeve 91. Multiple limiting sleeves 91 are fixedly connected to the bottom end of the conveying plate 81. Telescopic sliding plates 92 are slidably connected to the limiting sleeves 91. Reinforcing rods 94 and linkage rods 95 are fixedly connected between the multiple telescopic sliding plates 92. A scraping plate 93 is fixedly connected to the end of the reinforcing rod 94. A third cylinder 96 is installed between the linkage rod 95 and the bottom end of the conveying plate 81. Then, the second cylinder 83 adjusts the angle of the conveying plate 81. The third cylinder 96 extends and drives the multiple telescopic sliding plates 92 to slide via the linkage rod 95. The telescopic sliding plates 92 move the scraping plate 93 to the bottom end of the paper tube. Then, the second cylinder 83 retracts, causing the angle of the conveying plate 81 to reset. The scraping plate 93 then scrapes the paper tube and transfers it onto the conveying plate 81. Under gravity, the paper tube rolls to the finished product area. Finally, the scraping plate 93 and the lifting plate 71 return to their original positions to avoid obstructing the movement of the stop block 65.

[0037] In use, the raw material is first placed onto two first trays 51. At this time, the first rollers 52 support the material. The first servo motor 54 is then activated, driving the first lead screw 53 to rotate. The lead screw 53 drives the slider 56 to move along the first track 55. Next, the abutment rod 57 contacts one end of the material. Limited by the first protrusion 59 and the second protrusion 591, the abutment rod 57 only has a unidirectional rotation function. The abutment rod 57 then vertically pushes the material to slide on the first rollers 52 until the other end of the material contacts the baffle 66. Next, the pressing component 3 contacts the raw material and drives it to rotate, and the cutting component 4 contacts the raw material to cut it. The abutment rod 57, which has a unidirectional rotation effect, automatically folds after contact with the pre-placed raw material during reset, ceasing to push the material. After reset, it automatically pops out under the action of the reset torsion spring 58 to push the material. During processing, the position of the stop block 65 needs to be preset according to requirements. Then, the second servo motor 67 is started. The second servo motor 67 drives the stop block 65 to move along the second track 63 through the second lead screw 64. When adjusted to the predetermined position, the conveying mechanism 5... One end of the raw material is pushed into contact with the baffle 66. After cutting, the first servo motor 54 and the second servo motor 67 rotate synchronously in the same direction. The baffle 65 retracts while the slider 56 moves forward, thus facilitating the movement of the cut paper tube to the top of the lifting plate 71. After the paper tube is moved, the first cylinder 72 is activated, raising the height of the lifting plate 71 to a suitable height for subsequent material transfer. Then, the second cylinder 83 adjusts the angle of the conveyor plate 81, and the third cylinder 96 extends, driving multiple telescopic slide plates 92 via the linkage rod 95. The sliding and telescopic slide plate 92 moves the scraper plate 93 to the bottom of the paper tube. Then, the second cylinder 83 retracts, causing the conveyor plate 81 to return to its original angle. The scraper plate 93 then scrapes the paper tube and transfers it onto the conveyor plate 81. Under the action of gravity, the paper tube rolls to the finished product area. Then, the scraper plate 93 and the lifting plate 71 return to their original positions to avoid obstructing the movement of the stop block 65. The first servo motor 54 and the second servo motor 67 rotate synchronously. The slider 56 no longer resists the material that has not been completely cut. The stop plate 66 pushes the raw material to the position of the cutting component 4 to continue the subsequent unfinished cutting task. This process is repeated.
