Description

Technical Field

[0001] The utility model relates to the technical field of plate cutting equipment, in particular to a plate cutting device used for producing trolley cases. Background Art

[0002] A trolley case is a kind of travel equipment that is easy to carry and practical. It is usually composed of a trolley and rollers, which makes the trolley case both portable and draggable, greatly reducing the burden of carrying luggage during travel. The emergence of this design has made the trolley case one of the most popular types of luggage. As for the materials of the trolley case, there are many kinds, including cloth boxes, ABS hard boxes, leather boxes, PC, etc. These materials not only give the trolley case a different appearance and touch, but also determine the performance characteristics of the trolley case, such as durability, weight and price, etc. When producing the trolley case, the sheet material needs to be adjusted;

[0003] The utility model with application number 201922115220.X discloses a sheet material cutting device for producing a trolley case. By providing a first screw rod, a conveyor belt, and a fixing part, when placing the sheet material, the sheet material can be placed on the conveyor belt to move the sheet material forward. The first motor drives the first screw rod to fix the fixing part above the sheet material to prevent the sheet material from shifting due to movement, thereby achieving the effect of stabilizing the sheet material transportation and solving the problem of unstable shifting of the sheet material during cutting, resulting in uneven cutting. By providing a second screw rod, an electric push rod, and a cutting knife, when the sheet material is transported to the bottom of the cutting knife, the cutting knife cuts downwards through the electric push rod, and at the same time, the movable sleeve moves left and right on the second screw rod, and friction causes the sheet material to be completely separated, thereby achieving the effect of accurately and quickly cutting the sheet material, solving the problem of the sheet material being connected during cutting and requiring secondary processing.

[0004] However, when the cutting knife in the above-mentioned sheet material cutting device for producing trolley cases descends to cut, the downward force applied to the sheet material will cause the two ends of the sheet material to warp up, affecting the cutting effect. Before cutting, the above-mentioned sheet material cutting device for producing trolley cases needs to manually measure the moving position of the sheet material to determine the cutting accuracy, resulting in low cutting efficiency. Therefore, the utility model proposes a sheet material cutting device for producing trolley cases to solve the problems existing in the prior art. Utility Model Content

The first slide block 8 is slidably matched with the first slide rail 7. A cutting mechanism is provided at the lower middle of the cutting table 1, and a measuring limit mechanism is provided on the other side of the cutting table 1. Before cutting, the electric telescopic rod 3 is extended to drive the lifting frame 4 to descend and drive the rubber pressure block 5 to descend to press the sheet material on the support plate 6 for limiting, which effectively prevents the sheet material from being displaced during cutting, and solves the problem that the two ends of the sheet material will be tilted when the cutting knife is descended to cut and the downward force is applied to the sheet material, thereby affecting the cutting effect.

[0022] The cutting mechanism includes a through slot 9, a screw 10, a first motor 11, a slide bar 12, a movable plate 13, a cutting disc 14 and a second motor 15. A through slot 9 is provided in the middle of the support plate 6. A through slot 9 is rotatably provided on one side of the bottom of the support plate 6. A first motor 11 is fixedly provided in front of one side of the support plate 6. The output end of the first motor 11 is connected to the screw 10 for driving. A slide bar 12 is fixedly provided on the other side of the bottom of the support plate 6. A movable plate 13 is slidably provided between the screw 10 and the slide bar 12. A cutting disc 14 is rotatably provided on the movable plate 13. A second motor 15 is fixedly provided on one side of the movable plate 13, and the output end of the second motor 15 is connected to the cutting disc 14. One side of the movable plate 13 is threadedly matched with the screw 10, and the other side of the movable plate 13 is slidably matched with the slide bar 12. When cutting, the first motor 11 drives the screw 10 to rotate back and forth, driving the movable plate 13 to reciprocate along the screw 10 and the slide bar 12, driving the cutting disc 14 to move, and the second motor 15 drives the cutting disc 14 to rotate for cutting, so as to prevent the cutting knife from pressing down and causing deformation of the sheet material.

[0023] The measuring and limiting mechanism comprises a second slide rail 16, a second slider 17, a limiting plate 18, a positioning hole 19, a through hole 20 and a latch 21. The second slide rail 16 is symmetrically fixed on the other side of the cutting table 1, and a second slider 17 is slidably provided on the second slide rail 16. A limiting plate 18 is fixed between the second sliders 17. Positioning holes 19 are symmetrically arranged on the other side of the cutting table 1, and through holes 20 are symmetrically provided on the limiting plate 18. A latch 21 is inserted into the through hole 20. The through hole 20 corresponds to the upper and lower positions of the positioning hole 19.

When it is necessary to accurately control the cutting length of the sheet material, the limiting plate 18 and the second slider 17 are driven to slide to the corresponding position as needed, and the latch 21 is inserted into the corresponding positioning hole 19 after passing through the through hole 20. When the sheet material is pushed to be loaded, the sheet material stops cutting after hitting the limiting plate 18 at the corresponding position, so that the cutting length of the sheet material is the same each time and is convenient to adjust, which effectively ensures the cutting accuracy and improves the cutting efficiency.

[0024] Feed rollers 22 are arranged and rotated on both sides of the cutting table 1. There are multiple groups of feed rollers 22. When the plate is pushed to move on the cutting table 1, the feed rollers 22 are driven to rotate to reduce friction.

[0025] When the cutting tool is cut, the second motor drives the cutting disc to rotate, and the first motor drives the screw rod to rotate alternately in positive and negative intervals, drives the moving plate to reciprocate along the screw rod and the sliding rod, so that the cutting disc can realize reciprocating cutting. After the cutting is completed, the electric telescopic rod retracts and drives the lifting plate and the rubber pressing block to rise. When the cutting size needs to be adjusted, the latch is pulled out and the limit plate is pushed to slide along the second sliding rail to a suitable position and the latch is inserted again.

[0026] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
