Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following description of the present invention with reference to the accompanying drawings and specific embodiments is provided for clarity and completeness.

As shown in fig. 1 to 5, the cutting device comprises an operation table 1 and a cutting mechanism arranged on the operation table 1, wherein the cutting mechanism comprises a portal support frame 2 fixed on the operation table 1, a hydraulic cylinder 3 fixed on the portal support frame 2, a fixing plate 4 driven by the hydraulic cylinder 3 and capable of moving up and down, and a cutter 5 fixed on the fixing plate 4.

The cutting knife is characterized in that a cutting knife abdicating notch 6 and an aligning strip 7 are arranged on the operating table 1, the cutting knife abdicating notch 6 is matched with the cutting knife 5, the cutting knife abdicating notch 6 is parallel to the cutting knife, and the cutting knife 5 is perpendicular to the aligning strip 7. When the end part of the sealing strip 19 needs to be cut into a certain angle, the included angle between the cutter and the aligning strip 7 can be adjusted, and the required angle can be cut by arranging the corresponding cutter abdicating notch 6. The outer side of the cutter abdicating notch 6 is provided with a material guide plate 8, the material guide plate 8 is arranged obliquely downwards, and sealing strip waste materials cut down conveniently slide downwards. A receiving hopper is arranged below the material guide plate 8 and can directly receive sealing strip waste materials sliding down from the material guide plate 8.

The end part of the sealing strip 19 is trimmed and cut off, when the end part of the sealing strip 19 is trimmed, the sealing strip 19 is placed on the operating platform 1 and aligned with the alignment strip 7, the end part of the sealing strip 19 is ensured to be perpendicular to the cutter 5, then the sealing strip is pushed towards the cutter 5 along the alignment strip 7, the sealing strip is stopped when the sealing strip is pushed to the cutter, and the hydraulic cylinder 3 is started to drive the cutter to cut off the end part of the sealing strip 19. The cut sealing strip end part slides into a collecting hopper along the material guide plate 8 to be collected.

In order to enable the knife edge cut by the cutter 5 to be smoother and the port of the sealing strip to be smoother and to meet the specified requirements, the two sides of the cutter 5 are symmetrically provided with the pressing mechanisms. The pressing mechanism comprises a pressing column 9, a pressing block 10 and a first spring 11, wherein the pressing column 9 is arranged on the fixing plate 4 in a sliding mode, the pressing block 10 is fixed to the lower end of the pressing column 9, the first spring 11 is sleeved on the pressing column 9, and two free ends are fixed to the pressing block 10 and the fixing plate 4 respectively.

When the hydraulic cylinder 3 drives the fixing plate 4 to drive the cutter 5 to move downwards, the two pressing blocks 10 press the two ends of the sealing strip 10 downwards firstly, and then the cutter 5 cuts off the sealing strip 19 downwards. When the cutting allowance is smaller, the sealing strip 19 can be pressed only by the pressing block 10 on the right side, and the cutter 5 can cut downwards.

The upper end of the pressing column 9 is provided with an anti-drop block 12 for preventing the pressing column 9 from separating from the fixing plate 4 under the inertia effect. Anticreep piece 12 with be provided with second spring 13 between still between fixed plate 4, second spring 13 suit is in compress tightly on the post 9, impact force is too big when effectively avoiding fixed plate 4 to push down damages whole mechanism. Meanwhile, due to the arrangement of the double springs, the phenomenon that the fixed plate 4 is inclined when the pressing mechanism is pressed on one side (one pressing block 10 presses the sealing strip 19) is effectively avoided, and the cutting effect is guaranteed.

The compact heap 10 is provided with lets a mouthful 14, let a mouthful 14 internal surface be provided with and take bellied layer that compresses tightly, compress tightly the layer and can adopt and take bellied rubber layer, when compact heap 10 pushes down sealing strip 19, can effectively increase and compress tightly the effect, sealing strip 19 removes when preventing to cut, tears sealing strip 19 in the incision department when avoiding cutting.

Still be provided with guide post 15 on the door shape support frame 2, be provided with on the fixed plate 4 and make the slotted hole of stepping down that guide post 15 passed through. The guide posts 15 effectively prevent the fixing plate 4 from tilting when moving downward. In order to further ensure that the fixed plate 4 does not incline, sliding blocks 16 are arranged on two sides of the fixed plate 4, guide grooves 17 are arranged on two side edges of the door-shaped support frame 2, and a clamping groove is formed between each sliding block 16 and the fixed plate 4, so that the clamping groove is clamped in the guide grooves 17 and slides up and down along the guide grooves 17.

In this embodiment, the three aligning strips 7 and the three groups of cutters 5 are arranged on the operating platform 1, so that one or more operators can operate on the operating platform 1 at the same time, and the working efficiency is improved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
