Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model. In addition, references to the terms "vertical", "horizontal", "front", "rear", etc., in the embodiments of the present utility model indicate that the apparatus or element in question has been put into practice, based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product is conventionally put in use, merely for convenience of description and to simplify the description, but do not indicate or imply that the apparatus or element in question must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model. It should be further noted that, unless explicitly stated or limited otherwise, terms such as "mounted," "connected," "secured," and the like in the description are to be construed broadly as, for example, "connected," either permanently connected, detachably connected, or integrally connected; either directly or indirectly through intermediaries, or in communication with each other. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

It should be noted that, the cutter is directly driven to cut through linear motion, and the phenomenon of uneven cutting depth and poor cutting stability are easy to occur under the influence of factors such as floating voltage. In particular, for materials that are not completely cut, but rather that have a need for cutting depth, cutting by the above-described scheme can greatly impact the quality of the material cut. Therefore, in order to perform quantitative cutting, the inventor adopts an eccentric wheel as a power mechanism for driving a cutter, namely, a rotating shaft of a rotating motor is connected with a rotating shaft of the eccentric wheel, and then the cutter is pushed to move up and down through the eccentric wheel to perform cutting. It can be known that when the rotation center of the eccentric wheel is unchanged, the track of the eccentric wheel is fixed when the eccentric wheel rotates, that is, even if the floating voltage influences the rotation speed of the rotating motor, the track of the eccentric wheel is not influenced, and therefore the track of the cutter moving up and down and the up and down movement amount are fixed, that is, the cutting depth of the cutter can be kept to be fixed and uniform, and the cutting stability is further improved.

The eccentric wheel can drive the cutter to move through the conveyor belt to cut, but the conveyor belt is long in transmission distance and flexible, so that the conveyor belt is easy to deform under stress, and uneven cutting is still easy to cause. The inventor therefore uses the eccentric 5 to drive the cutter 4 (such as the cutter described above) through the rigid sliding seat 3 to form the preferred cutting device of the present utility model, which will be described in detail below with reference to the accompanying drawings and with reference to the embodiments.

In one embodiment, as shown in fig. 1, a cutting device mainly comprises a guide upright 1, a sliding seat 3, a cutter 4 and an eccentric wheel 5.

Specifically, as shown in fig. 1, a guide upright 1 is mounted on a base 2; a sliding seat 3 is arranged on the guide upright column 1 in a sliding way, an accommodating hole 301 is arranged on the sliding seat 3, and an upper cutter 4 for cutting materials is also arranged at the lower end position of the sliding seat 3; the eccentric wheel 5 is adaptively accommodated in the accommodating hole 301, and the rotating shaft 501 of the accommodating hole 301 is connected with the rotating shaft of the rotating motor, so that the rotating eccentric wheel 5 forms a power mechanism for driving the sliding seat 3 to move up and down quantitatively.

In this way, the eccentric wheel 5 is driven to rotate by the rotating motor to directly drive the sliding seat 3 to slide up and down on the guide upright 1, so that the cutter 4 can be driven to stably move up and down to cut materials (such as materials placed on the base 2). And because the rotation track of the eccentric wheel 5 is fixed, the up-and-down movement track of the cutter 4 is fixed, namely the cutting depth of the cutter 4 can be kept uniform, and then the cutting stability can be improved, and the stability and balance of the cutting quality of materials are maintained.

As shown in the drawing of fig. 1, the outer contour of the eccentric 5 for the abutment slide 3 in the present embodiment is circular. Compared with a non-circular structure, the eccentric wheel 5 with the circular outline can be more closely attached to the side wall of the accommodating hole 301 in a larger area, and further can more stably drive the sliding seat 3 to move up and down. In order to further improve the fitting effect, the vertical width of the accommodating hole 301 in this embodiment is preferably matched with the diameter of the circle, and the left and right side walls of the accommodating hole 301 are arc structures adapted to the rotation track of the eccentric wheel 5.

In this embodiment, as shown in fig. 1, the sliding seat 3 is slidably connected to two spaced guide posts 1, and the eccentric 5 and the upper cutter 4 are disposed between the spaced guide posts 1. Compared with the single-position guide of the single guide upright 1, the two guide uprights 1 form multi-position guide, so that the sliding seat 3 can move up and down more stably under the action of the rotating eccentric wheel 5, and the moving stability of the upper cutter 4 arranged on the sliding seat 3 is improved, so that the cutting stability is improved.

Further, as shown in fig. 3, the rotation shaft 501 of the eccentric 5 is placed at the middle position of the two guide posts 1 at intervals. Specifically, it is preferable that the distance between the rotation center of the rotation shaft 501 and the left guide column 1 and the distance between the rotation center of the rotation shaft 501 and the right guide column 1 are the same, so that the layout of the entire structure is more balanced.

In combination with the production line environment, as shown in fig. 2, the embodiment further comprises a conveying device 6, preferably a conveyor belt or a conveying belt, the two conveying devices 6 arranged at intervals form a supporting structure for materials together, and a containing space for the upper cutter 4 to move is formed between the two conveying devices 6 at intervals. In this way, the continuous cutting of the materials in the transportation process can be carried out only by setting the conveying speed of the conveying device 6 to be constant and the rotating speed of the eccentric wheel 5 to be constant. And the length of the cut material can be adjusted by simply changing the conveying speed of the conveying device 6 or the rotating speed of the eccentric wheel 5.

It should be noted that, by the above-mentioned cutting device, the material that is not completely cut but that is required for the cutting depth can be cut, and the material that is required to be completely cut can also be cut. In this case, in order to cut off the material better, as shown in fig. 7, a lower cutter 7 is provided on the base 2 so as to be positioned in association with the upper cutter 4, and the upper cutter 4 and the lower cutter 7 together form a shearing structure for the material.

Of course, in order to facilitate the replacement and maintenance of the cutter structure with a short service life, the upper cutter 4 in this embodiment is detachably mounted on the sliding seat 3 through a screw structure, and the lower cutter 7 is detachably mounted on the base 2 through a screw structure. Specifically, the upper cutter 4 is fastened to the slide base 3 and the lower cutter 7 is fastened to the base 2 by means of several screws.

Further, as shown in fig. 6 and fig. 7, in this embodiment, a protruding portion 502 is disposed on the eccentric wheel 5 around the outer contour, a groove 3011 is disposed on the side wall of the accommodating hole 301, and the protruding portion 502 is engaged with the groove 3011. Therefore, on one hand, the eccentric wheel 5 and the sliding seat 3 can be prevented from falling off, and the connection stability between two movable components is improved; on the other hand, the laminating area between eccentric wheel 5 and sliding seat 3 has been increased, and then sliding seat 3 can more steadily reciprocate under the drive of eccentric wheel 5, and then improves the stability of cutting.

In order to enable the eccentric wheel 5 with the protruding portion 502 to be more conveniently and adaptively installed in the accommodating hole 301, as shown in fig. 5, the sliding seat 3 in the embodiment is assembled by an upper sliding seat 3a and a lower sliding seat 3b, and a first notch 3a01 on the upper sliding seat 3a and a second notch 3b01 on the lower sliding seat 3b are assembled together to form the accommodating hole 301.

Wherein, after the eccentric wheel 5 is installed, the upper sliding seat 3a and the lower sliding seat 3b can be fastened in a non-detachable way by using glue, rivets, welding and the like. However, since the eccentric 5 cannot be replaced and repaired, the slide holder 3 of the present embodiment is preferably assembled by the upper slide holder 3a and the lower slide holder 3b through the bolt assembly 8 as shown in fig. 5. Specifically, the bolt assembly 8 includes a bolt 801 and a fastening nut 802, wherein the lower end of the bolt 801 sequentially passes through the upper sliding seat 3a and the lower sliding seat 3b, the fastening nut 802 is screwed to one end of the bolt 801 exposed to the upper side of the upper sliding seat 3a and to one end of the bolt 801 exposed to the lower side of the lower sliding seat 3b, and the upper and lower fastening nuts 802 together form a clamping structure for the upper sliding seat 3a and the lower sliding seat 3b, so that the upper sliding seat 3a and the lower sliding seat 3b are fastened to form the sliding seat 3. When the eccentric wheel 5 needs to be disassembled and maintained, the upper sliding seat 3a and the lower sliding seat 3b can be driven to be separated only by sequentially disassembling the fastening nut 802 and the bolt 801 so as to disassemble the eccentric wheel 5.
