Description

Technical Field

[0001] The utility model belongs to the technical field of slitting equipment, and in particular relates to a feeding mechanism and a slitting machine. Background Art

[0002] The current capacitors are mostly made of polypropylene film, capacitor paper and aluminum foil, and sealed with plastic or metal shell, and then connected with external wires or guides. In the production process of the capacitor, various roll film products such as aluminum foil, polypropylene film, capacitor paper, etc. need to be cut to reach the appropriate specifications. As disclosed in the slitting machine of publication number CN105922323A, the parts to be cut on the storage shaft are rolled on the receiving shaft after being cut by the slitting knife, so as to realize the automatic cutting of the parts to be cut. However, after the parts to be cut on the storage shaft are cut, it is necessary to replace a new storage shaft with the parts to be cut, and the new storage shaft can only be placed on the slitting machine frame by manually lifting it up and placing it on the frame. For the heavy parts to be cut, it takes many people to lift them up and place them on the frame, which is a relatively large labor burden for the staff, and the feeding efficiency is also low.

DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] like Figure 1-Figure 5 As shown, a feeding mechanism comprises:

[0030] A lifting unit disposed on the frame 400 includes two lifting members 100 that can move linearly in the vertical direction;

[0031] There are two feeding channels 200, and a gap is provided between the two feeding channels 200 to form a space for accommodating the product roll 500. In the vertical direction, the highest lifting position of the lifting member 100 is not lower than the position of the feeding channel 200;

[0032] The locking member includes a locking portion 201 disposed on the feed channel 200 . When the rotating shaft portion 501 on the product roll 500 moves to a preset position on the feed channel 200 , a locking space for restricting the rotating shaft portion 501 is formed between the locking portion 201 and the feed channel 200 .

[0033] In this embodiment, the product roll 500 is manually pushed to the rotating shaft parts 501 at both ends thereof, which are located above the lifting member 100. Then, the lifting member 100 works to drive the product roll 500 to be lifted in the vertical direction. When the product roll 500 is lifted to the preset position, the product roll 500 is manually pushed to enter the feed channel 200. Then, the locking part 201 is operated to confine it in the locking space to ensure that the product roll 500 does not shake significantly during the operation of the slitting machine. The use of a lifting mechanism instead of manual lifting and transportation can effectively reduce manual labor intensity and improve loading efficiency.

[0034] Specifically, the lifting member 100 includes a lifting block 101 , and the lifting block 101 can be abutted against the rotating shaft portion 501 to lift it. A lifting driving member 102 is fixedly provided on the frame 400 and is drivingly connected to the lifting block 101 .

[0035] In this embodiment, the lifting block 101 is located on the outside of the frame 400, which is convenient for shifting the product roll 500. The lifting drive member 102 can be a cylinder. The lifting block 101 is fixed to the cylinder shaft of the cylinder, and a control button is also provided on the frame 400 to connect with the cylinder to control the operation of the cylinder.

[0036] like Figure 2-Figure 3 As shown, preferably, two feed plates 202 are provided on the frame 400, the feed channel 200 is provided on the corresponding feed plate 202, and the feed channel 200 includes a first straight line segment 203 and a second straight line segment 205, the rotating shaft portion 501 moves along the first straight line segment 203, and the first straight line segment 203 and the second straight line segment 205 are connected by a curved segment 204, and when the rotating shaft portion 501 moves to a preset position along the first straight line segment 203, the locking portion 201 passes through the second straight line segment 205 and the curved segment 204 to form a locking space.

[0037] It is worth mentioning that a material storage shaft is provided in the product roll 500 , and both ends of the material storage shaft are provided with relatively rotatable shaft parts 501 , and the shaft parts 501 are provided with limiting ring grooves.

[0038] In this embodiment, the first straight segment 203 is used to support and guide the rotating shaft portion 501 on the product roll 500. When the lifting block 101 lifts the product roll 500 to a preset position, that is, the upper surface of the lifting block 101 is not lower than the position of the first straight segment 203, the product roll 500 is manually pushed toward the direction of the frame 400, so that the rotating shaft portions 501 at both ends move forward along the corresponding first straight segment 203 until the rotating shaft portion 501 abuts against the curved segment 204, and then the locking portion 201 passes through the second straight segment 205 and the curved segment 204 to form a locking space to prevent the product roll 500 from shaking drastically when the slitting machine is working.

[0039] It is worth mentioning that the first straight line segment 203 and the second straight line segment 205 are preferably arranged in a horizontal direction.

[0040] Further preferably, a limit block 103 is provided on the lifting block 101 , and during the vertical movement of the lifting block 101 , a limit interval is formed between the limit block 103 and the feed plate 202 to limit the rotating shaft portion 501 .

[0041] In this embodiment, when the rotating shaft parts 501 at both ends of the product roll 500 are located above the corresponding lifting blocks 101, the corresponding limit blocks 103 and the feed plates 202 are respectively located on both sides of the rotating shaft parts 501. As the product roll 500 is lifted, the limit blocks 103 and the feed plates 202 cooperate to restrict its rolling to prevent it from falling from the lifting blocks 101 and causing safety hazards.

[0042] Further preferably, a limiting portion is provided on the first straight segment 203 to prevent the rotating shaft portion 501 from being separated.

[0043] In this embodiment, the limiting portion includes a limiting plate 206 arranged on the feed plate 202, and the limiting plate 206 is located at the end of the first straight segment 203. The highest lifting position of the lifting block 101 is preferably set higher than the position of the first straight segment 203. When the product roll 500 is pushed from the lifting block 101 to the first straight segment 203, the movement of the product roll 500 will have a certain drop. Then, when the product roll 500 just enters the first straight segment 203, it may vibrate and cause the product roll 500 to detach from the first straight segment 203. The setting of the limiting block 103 can abut and limit the rotating shaft portion 501 to prevent it from detaching from the first straight segment 203.

[0044] Further preferably, the locking portion 201 includes a locking rod that can move linearly, and a locking driving member 207 is provided on the feed plate 202 and is drivingly connected to the locking rod.

[0045] In this embodiment, under normal conditions, the locking rod is retracted in the feed plate 202 , and only when the product roll 500 moves to a preset position on the first straight segment 203 , the locking rod will pass through the feed plate 202 .

[0046] Further preferably, the locking end of the locking rod is provided with an arcuate abutting surface 208, and the shaft portion 501 of the product roll 500 is cylindrical in shape, so when the locking rod abuts against the shaft portion 501, the contact area with the shaft portion 501 is increased.

[0047] A slitting machine includes the above-mentioned feeding mechanism and a frame 400. The feeding mechanism is arranged on the frame 400, and a slitting rod 300 is also arranged on the frame 400. A plurality of slitting knives 301 are arranged on the slitting rod 300. The slitting rod 300 can rotate relative to the frame 400, and an operating part is arranged on the frame 400 and is drivingly connected to the slitting rod 300.

[0048] Specifically, the operating part includes an operating hand wheel 302 , and power is transmitted between an operating rod of the operating hand wheel 302 and the slitting rod 300 via a worm gear pair.

[0049] In this embodiment, the slitting knife 301 and the frame 400 are rotatable. The cutting depth of the slitting knife 301 can be controlled by rotating the slitting rod 300. In order to facilitate the rotation control of the slitting rod 300, an operating hand wheel 302 is provided on the frame 400. In order to intuitively observe the cutting situation of the slitting knife 301 during the rotation of the operating hand wheel 302, the operating hand wheel 302 is set on the front side of the frame 400. Therefore, the output force between the operating hand wheel 302 and the slitting rod 300 needs to be reversed through a worm gear pair.
