[0032] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0033] like Figure 1 As shown, this embodiment provides a feeding device for cutting paper tubes, comprising: a tilting frame 100, a storage box 200, a lifting assembly 300, a limiting platform assembly 400 and a pushing assembly 500;

[0034] The tilting frame 100 supports a storage box 200 for receiving paper tubes. One side wall of the storage box 200 is set as a first inclined surface 201. A lifting component 300 is provided at the bottom of the first inclined surface 201. A limiting platform component 400 is provided at the top pushed by the lifting component 300 along the first inclined surface 201. A pushing component 500 is provided at the end of the limiting platform component 400 away from the storage box 200. The pushing component 500 pushes the paper tube toward the cutting machine.

[0035] Specifically, the tilting frame 100 is composed of several iron rods or square steels so that the entire loading device is tilted, and natural gravity can be used instead of a conveyor belt or power assembly to reduce costs. The top of the tilting frame 100 is supported by a storage box 200 for receiving and storing spare paper tubes. The storage box 200 can be built from iron rods or panels. One side wall of the storage box 200 is set as a first inclined surface 201, so that the lifting assembly 300 at the bottom of the first inclined surface 201 can push the paper tubes along the first inclined surface 201 to the limit platform assembly 400. Since the storage box 200 is tilted, the paper tubes will automatically move downward. Each time the lifting assembly 300 pushes multiple paper tubes upward at once, it is necessary to set the limit platform assembly 400 so that the paper tubes can be arranged in advance and fed into the cutting machine one by one. The limiting platform assembly 400 is located on the short side of the tilting frame 100. With the help of gravity, a single paper tube is dropped onto the pushing assembly 500. The pushing assembly 500 then pushes the paper tube in, replacing manual feeding.

[0036] In an embodiment of the present invention, the bottom surface of the storage box 200 is a second inclined surface 202, the angle between the first inclined surface 201 and the second inclined surface 202 is 60° to 90°, and a first through hole is opened on the second inclined surface 202 near the first inclined surface 201, and a lifting assembly 300 is provided along the circumference of the first through hole.

[0037] The lifting assembly 300 includes a first pushing block 301 disposed in the first through hole. A first cylinder 302 is disposed at the bottom end of the first pushing block 301 . The first cylinder 302 is fixed on the tilting frame 100 .

[0038] Specifically, the bottom surface of the storage box 200 is a second inclined surface 202, which is the bottom surface of the storage box 200. The second inclined surface 202 is inclined upward and to the right relative to the ground, and the inclination angle is 25° to 35° so that the paper tube can slide to the lower left corner; the second inclined surface 202 and the first inclined surface 201 form an angle of 60° to 90°, so that a large number of paper tubes in the storage box 200 are accumulated in the lower left corner of the storage box 200.

[0039] A first through hole is provided on the second inclined surface 202 near the first inclined surface 201. The first through hole is in the shape of an elongated rectangle. A first pushing block 301 in the lifting assembly 300 is provided along its circumference. The first pushing block 301 is in the shape of a rectangle. Each time the first cylinder 302 pushes upward, it drives the first pushing block 301 to send 3 to 5 paper tubes upward to the limiting platform assembly 400.

[0040] In an embodiment of the present invention, the position limiting platform assembly 400 includes a third inclined surface 401 connected to the first inclined surface 201. A hollow frame 402 is provided at the top of the third inclined surface 401. A plurality of tilting rods 403 are fixed to the top of the hollow frame 402, which have the same tilt angle as the third inclined surface 401. A second through hole is formed on the surface of the third inclined surface 401. A second push block 404 is provided along the circumference of the second through hole. A second cylinder 405 is provided at the bottom of the second push block 404, and the second cylinder 405 is fixed to the tilting frame 100. A stopper 406 is provided on the surface of the third inclined surface 401 near the second push block 404. A lubricating layer is applied to the surface of the third inclined surface 401.

[0041] Specifically, the limiting platform assembly 400 includes a third inclined surface 401 connected to the first inclined surface 201. The third inclined surface 401 is formed by the inclined frame 100, and the internal angle between the third inclined surface 401 and the first inclined surface is an angle of 60° to 90°, so that the paper tube sent up from the first pushing block 301 is sent to the surface of the third inclined surface 401. The top of the third inclined surface 401 near the first inclined surface 201 is fixed with a door-shaped hollow frame 402. The paper tubes pushed up from the first pushing block 301 all pass through the hollow frame 402 and slide down in an orderly manner along the third inclined surface 401 according to gravity; a number of inclined rods 403 with the same inclination angle as the third inclined surface 401 are fixed to the top of the hollow frame 402. Two to four tilting rods 403 are evenly spaced, with one end welded to the hollow frame 402. The tilting rods 403 and the third inclined surface 401 are inclined at the same angle, forming a limiting space that restrains the paper tubes and allows them to slide downward one by one into the second through-hole. The surface of the third inclined surface 401 is provided with a second through-hole, and along its circumference, a second pusher block 404 is positioned. The bottom end of the second pusher block 404 is provided with a pusher rod of a second cylinder 405, which is fixed to the tilting frame 100. When the paper tubes slide onto the second pusher block 404, it springs up, dropping the paper tubes one by one into the pusher assembly 500.

[0042] In one implementation of this embodiment, if the inclination angle of the third inclined surface 401 is large, multiple paper tubes may slide down quickly, and the pushing component 500 needs to be pushed in one by one. The pushing speed of the pushing component 500 may be slower than the sliding speed. At this time, a stop block 406 is provided on the surface of the third inclined surface 401 near the second pushing block 404, which can help intercept the paper tubes. At this time, it is only necessary to increase the pushing force of the second cylinder 405 to allow the paper tubes to bounce over the surface of the stop block 406 one by one and fall into the pushing component 500.

[0043] In one implementation of this embodiment, the third inclined surface 401 is in the shape of a plate, and a lubricating layer may be laid on the surface to prevent the paper tube from being blocked on the surface of the third inclined surface 401 and to help it fall quickly.

[0044] In an embodiment of the present utility model, the pushing assembly 500 includes a third cylinder 501 fixed on the tilting frame 100, the output end of the third cylinder 501 is fixedly connected to a pneumatic slide rail 502, the side of the pneumatic slide rail 502 is fixedly connected to a loading platform 503, the loading platform 503 is located on one side of the limiting platform assembly 400, and a movable push rod 504 is sleeved on the slide rail of the pneumatic slide rail 502, and the movable push rod 504 is horizontally arranged with the loading platform 503.

[0045] The movable push rod 504 includes a push rod frame 505 sleeved on the slide rail of the pneumatic slide rail 502 and a conical push head 506. The diameter of the push head 506 is the same as the diameter of the paper tube.

[0046] Specifically, the pushing assembly 500 includes a third cylinder 501 fixed on the tilting frame 100. The output end push rod of the third cylinder 501 is fixedly connected to the pneumatic slide 502. The third cylinder 501 pushes the pneumatic slide 502 to move left and right. When it is close to one side of the limit platform assembly 400, it is convenient to catch the paper tube. When it is away from the side of the limit platform assembly 400, it is convenient for the docking cutting machine to push the paper tube in. The side of the pneumatic slide 502 is fixedly connected to a loading platform 503. The loading platform 503 includes an L-shaped bracket 507 and a V-shaped platform 508 fixed to the side of the pneumatic slide 502. The L-shaped bracket is used to support the V-shaped platform 508. One end is fixedly connected to the side wall of the pneumatic slide 502, and the other end is fixedly connected to the V-shaped platform 508. The loading platform 503 is located on one side of the limit platform assembly 400. The shape of the V-shaped platform 508 is just right to hold a paper tube.

[0047] A movable push rod 504 is mounted on the slide rail of the pneumatic slide rail 502. The movable push rod 504 is horizontally arranged with the loading platform 503. The movable push rod 504 is located behind the loading platform 503. The movable push rod 504 is mounted on the pneumatic slide rail 502 through a semicircular push rod frame 505 at the bottom end. It can be moved back and forth to push the paper tube into the cutting machine. The conical push head 506 has a diameter the same as the diameter of the paper tube, and is also for alignment with the paper tube to facilitate feeding.

[0048] The utility model also provides a cutting machine, comprising the feeding device for cutting paper tubes, forming a complete cutting production line.

[0049] Based on the above embodiment, the working process of the feeding device and cutting machine for cutting paper tubes provided by the embodiment of the present invention is as follows:

[0050] Multiple paper tubes are placed in a storage box 200 supported by an inclined frame 100. When a paper tube needs to be fed into the cutting machine, the lifting assembly 300 (comprising a first pusher 301 and a first cylinder 302) activates, pushing the paper tube along the first inclined surface 201 to the limiting platform assembly 400. The limiting platform assembly 400 comprises a third inclined surface 401, a hollow frame 402, and an inclined rod 403. These structures work together to ensure the orderly sliding of the paper tube.

[0051] At this point, the second air cylinder 405 activates, pushing the second push block 404 upward, allowing a single paper tube to leap out of the stop block 406 and continue sliding along the third inclined surface 401 onto the V-shaped platform 508. Simultaneously, the third air cylinder 501 pulls the pneumatic slide 502 toward the stop platform assembly 400, allowing the V-shaped platform 508 to smoothly catch the paper tube. The third air cylinder 501 again pulls the pneumatic slide 502 away from the stop platform assembly 400, aligning it with the cutting machine's inlet. The movable push rod 504 then moves rearward, and the push head 506 smoothly feeds the paper tube in.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
