Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production, and in particular to a device for cutting and unloading coated paper tubes. Background Art

[0002] Paper tubes are cylindrical products made from paper. They are widely used as cores for textiles, films, plastic bags, and other rolled materials. They are also used in gift packaging and decorative items. They are popular for their low cost and recyclability.

[0003] The production process of paper tubes can be broadly divided into paper strip manufacturing, gluing, forming, curing, cutting, testing, and packaging. When cutting paper tubes, workers must manually hold one end of the tube while the cutting mechanism cuts the tube. After cutting, the worker removes the tube, which is labor-intensive and difficult to maintain. A prior art search revealed that Chinese Patent Publication No. CN214522331U discloses a "Tube Rolling Machine for Facilitating Paper Tube Cutting and Cutting." This system utilizes a receiving plate and a placement plate positioned behind the cutting mechanism to receive and transfer the cut tubes, eliminating manual labor. However, it's worth considering that, on the one hand, the horizontal receiving plate requires additional baffles to prevent the tubes from rolling and falling. On the other hand, the receiving plate is fixed in position. When cutting small, long tubes, the tube extends from the cutting nozzle and hangs above the receiving plate. Gravity causes the free end of the tube to drop, resulting in a tilted cut, presenting certain limitations.

[0004] Therefore, in order to solve the above problems, a related facility that is more in line with usage needs needs to emerge. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a coated paper tube cutting and unloading device to solve the problem of uneven cutting edges in the existing device during the cutting and unloading process of paper tubes with smaller diameters.

[0006] Based on the above-mentioned purpose, the utility model provides a coated paper tube cutting and unloading device, including a main body bracket, a base is arranged outside the main body bracket, a height adjustment component is arranged between the main body bracket and the base, a rotating component is arranged on the top of the main body bracket, a hinge receiving platform is arranged on the top of the rotating component, and a folding component is arranged at the bottom middle part of the hinge receiving platform.

[0007] Furthermore, the main support includes a bottom plate, and the first support rod and the second support rod are fixedly connected to both ends of the bottom plate respectively. The first support rod and the second support rod pass through and are slidably connected to the top of the base.

[0008] Furthermore, the height adjustment assembly includes a screw rod, a handwheel is fixedly connected to the top of the screw rod, a nut is sleeved on the middle and lower part of the screw rod, the bottom of the nut is fixedly connected to the base plate, the bottom end of the screw rod is fixedly connected to a support bearing, and the support bearing is fixedly connected to the base.

[0009] Furthermore, the rotating assembly includes a first robotic arm and a second robotic arm. The first robotic arm is a T-shaped structure and includes a web and a flange. The bottom end of the web is rotatably connected to the first support rod. A first cylinder is provided on the side of the first support rod away from the end of the base plate. The output end of the first cylinder is rotatably connected to the end of the flange. The bottom end of the second robotic arm is rotatably connected to the second support rod. The top end of the web and the top end of the second robotic arm are respectively rotatably connected to two receiving platform supports.

[0010] Furthermore, the hinge receiving platform includes a fixed blade and a folding blade, the fixed blade is hingedly connected to the folding blade, the fixed blade is fixedly connected to the top of the receiving platform support, and the fixed blade is placed at an angle.

[0013] Beneficial effects of the utility model:

[0014] The utility model adjusts the height of the receiving platform by arranging a height adjustment component, so that vertical support is provided after the cutting nozzle is extended when cutting paper tubes of different diameters, avoiding the free end of the paper tube with a smaller diameter and a longer cutting length from hanging and falling after being extended from the cutting nozzle, thereby ensuring a smooth incision.

[0015] The utility model is provided with a hinged inclined bearing platform, which effectively prevents the cut paper tube from sliding and rolling off the bearing platform, thereby avoiding the use of a baffle. The rollers arranged on the bearing platform reduce the friction of the paper tube when it extends out of the cutting nozzle on the bearing platform.

[0016] The rotating assembly provided in the utility model causes the supporting platform to descend and move away from the cutting mechanism when transferring the cut paper tube, thereby ensuring safety and non-interference. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] This embodiment proposes a coated paper tube cutting and unloading device, such as Figure 1 As shown, the main bracket 1 consists of a base plate 101, a first support rod 1021 and a second support rod 1022, which is slidably connected to the base 2 through a height adjustment assembly. A rotating assembly is set on the top of the main bracket 1, a hinge receiving platform 5 is set on the top of the rotating assembly, and a folding assembly is set at the bottom middle part of the hinge receiving platform 5.

[0025] The height adjustment component is a screw rod 301 nut 303 system, which adjusts the height of the main bracket 1 by converting the rotation of the screw rod 301 into the translation of the nut 303. A handwheel 302 is set at the top of the screw rod 301 for easy operation. The bottom end of the screw rod 301 is rotatably connected to the base 2 through a support bearing 304. The nut 303 is fixedly connected to the bottom plate 101 of the main bracket 1. The height adjustment component is used to adjust the height of the hinge receiving platform 5 to ensure that paper tubes of different diameters fall on the hinge receiving platform 5 for support when cutting, thereby ensuring a smooth incision.

[0026] The rotating assembly includes a T-shaped first robotic arm 401 and a second robotic arm 402. The bottom end of the web 4011 in the T-shaped structure of the first robotic arm 401 is rotatably connected to the first support rod 1021, the end of the flange 4012 is rotatably connected to the output end of the first cylinder 403, the bottom end of the second robotic arm 402 is rotatably connected to the second support rod 1022, and the top end of the web 4011 and the top end of the second robotic arm 402 are rotatably connected to two receiving platform supports 404. The rotating assembly is used to keep the hinge receiving platform 5 away from the cutting mechanism during unloading to ensure safety and prevent interference.

[0027] The hinge receiving platform 5 includes a fixed blade 501 and a folding blade 502 that are hingedly connected. The fixed blade 501 is placed at an angle and fixedly connected to the receiving platform support 404. Two sets of rollers 503 are provided in a groove near one end of the cutting mechanism on the hinge receiving platform 5 to reduce friction when the cutting nozzle is extended during paper tube cutting.

[0028] Folding components such as Figure 4 The system shown includes a second cylinder 601 fixedly connected to the bottom center of the fixed blade 501. The output end of the second cylinder 601 is rotatably connected to a third robotic arm 602. The other end of the third robotic arm 602 is rotatably connected to a connecting rod 603 fixed to the bottom center of the folding blade 502. The folding assembly is used to tilt the folding blade 502 during unloading, allowing the paper tube to slide from the hinge receiving platform 5 onto the unloading platform.

[0029] Working process and principle: This device is arranged between the cutting mechanism and the unloading area platform in the paper tube production line. It is used to receive the cut paper tubes and transfer them to the unloading area for subsequent processing. Therefore, its working process includes the cutting and receiving process and the transfer and unloading process.

[0030] Cutting process as Figure 2 and Figure 4 As shown, when the device is in the cutting process, the height of the main support 1 is adjusted by rotating the hand wheel 302 to drive the screw 301 and the nut 303 system, so that when the paper tube to be cut extends out of the cutting nozzle, the bottom of the paper tube falls horizontally on the hinge receiving platform 5. At this time, the cylinder is started, and the output ends of the first cylinder 403 and the second cylinder 601 are in an extended state. The first mechanical arm 401, the second mechanical arm 402 and the third mechanical arm 602 are in a vertical position, and the folding blade 502 and the fixed blade 501 are arranged in a "V" shape. During the cutting process, the paper tube extends out of the cutting nozzle and falls on the hinge receiving platform 5. The friction is reduced by the roller 503 during the extension process. The V-shaped structure of the hinge receiving platform 5 prevents the cut paper tube from sliding and rolling off the hinge receiving platform 5.

[0031] Unloading process Figure 3 and Figure 5As shown, the cylinder is closed, and the output ends of the first cylinder 403 and the second cylinder 601 retract. The retraction of the first cylinder 403 causes the first mechanical arm 401 to drive the second mechanical arm 402 to rotate, thereby driving the hinge receiving platform 5 to move downward and away from the cutting device, avoiding collision with the cutting mechanism during unloading; at the same time, the retraction of the second cylinder 601 causes the third mechanical arm 602 to rotate, and drives the folding blade 502 to rotate downward through the connecting rod 603 until the folding blade 502 rotates to the same inclined plane as the fixed blade 501. At this time, the paper tube that falls on the hinge receiving platform 5 during the cutting process slides out of the hinge receiving platform 5 due to gravity and falls on the unloading area platform, and unloading is completed.
