Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a light box cloth processing and cutting device. Background Art

[0002] The light box cloth is a light box sign fabric composed of two layers of PVC and one layer of high-strength mesh cloth. It is divided into two types: internal lighting and external lighting. When producing light box cloth, light box cloth of different lengths needs to be cut, so it is necessary to provide a light box cloth processing and cutting device.

[0003] When processing and cutting the existing light box cloth, the up and down positions of the cutting knife cannot be adjusted, which makes the operation inconvenient and easily causes tilting and wrinkling when the light box cloth roll is pulled. The stretching stability is poor when cutting the light box cloth, which reduces the applicability of the device. Summary of the invention

[0004] The purpose of the utility model is to provide a light box cloth processing and cutting device with strong applicability in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

The number of the frames is two, and the two frames are arranged opposite to each other. The two ends of the flat plate are respectively hinged to the two frames. The positioning member is located between the frame and the flat plate and the number of the positioning members is two. The two positioning members are respectively connected to the corresponding frames and are arranged opposite to each other. The positioning member can change the circumferential position of the flat plate and perform positioning; the adjusting member is connected between the two frames, the driving member is connected to the lower part of the adjusting member, the adjusting member can change the upper and lower positions of the driving member, the cutting knife is connected to the driving member, and the driving member can drive the cutting knife to move for cutting.

[0007] The utility model creatively arranges a frame, a flattening plate, a positioning member, an adjusting member, a driving member and a cutting knife. The end cross-sectional surface of the flattening plate is a combination of a circle and an equilateral triangle, that is, an inverted water drop shape. The flattening plate is hinged to the frame with the center of the end circle as a hinge point. When the flattening plate is against the light box cloth, the circumferential position of the flattening plate can be adjusted and positioned by the positioning member, thereby increasing the flatness of the cut light box cloth, making it less likely to produce tilting and wrinkles, and improving the stability of stretching when cutting the light box cloth.

[0008] The light box cloth first passes through the flat plate and then passes under the driving member. When the light box cloth is being processed and cut, the upper and lower positions of the cutting knife connected to the driving member can be changed through the adjusting member, which is convenient to operate and improves the applicability of the device.

[0009] In the above-mentioned light box cloth processing and cutting device, the flat plate includes a semicircular groove, the semicircular groove is located on the side of the flat plate, and the semicircular groove is a concave semicircular shape; the number of the semicircular grooves is several, and the several semicircular grooves are evenly distributed circumferentially with the hinge point between the end of the flat plate and the frame as the center.

[0010] The arrangement of a plurality of semicircular grooves enables the flat plate to be rotated in a circumferential direction and positioned at different positions with the hinge point as the center through the positioning piece.

[0011] In the above-mentioned light box cloth processing and cutting device, the positioning piece includes a groove, a spring and a ball. The inner side of the frame has a hollow groove. The spring and the ball are connected to the inside of the groove. The two ends of the spring are respectively connected to the groove and the ball. Under the elastic force of the spring, the ball has a tendency to rest against the semicircular groove.

[0012] Under normal conditions, the concave semicircular shape of the semicircular groove enables the ball to be more closely attached to the semicircular groove. Under the action of external force, the ball can leave the semicircular groove and slide along the side end of the slide rail until it rests against the next semicircular groove under the elastic force of the spring, thereby achieving the positioning of the flat plate and the change of the circumferential position.

[0013] In the above-mentioned light box cloth processing and cutting device, the adjusting member includes a cross frame and an adjusting screw, the two ends of the cross frame are respectively fixedly connected to two frames, the adjusting screw is threadedly connected to the cross frame, and the bottom end of the adjusting screw is rotatably connected to the driving member.

[0014] Turning the adjusting screw can drive the driving member to move up and down.

[0015] In the above-mentioned light box cloth processing and cutting device, the driving part includes a movable plate and a screw, the movable plate is opposite to the cross frame, the bottom end of the adjusting screw is rotatably connected to the movable plate, the side of the movable plate has a recessed slide groove, an inner side wall of the slide groove is fixedly connected with a motor, one end of the screw is connected to the output end of the motor, and the other end of the screw is rotatably connected to the other inner side wall of the slide groove.

[0016] The starting motor can drive the screw to rotate.

[0017] In the above-mentioned light box cloth processing and cutting device, the driving member also includes a slider, the slider is threadedly connected to the screw rod, and the cutting knife is fixedly installed on the side of the slider.

[0018] The size of the slider matches the slide slot. The starting motor can drive the screw to rotate and drive the cutting knife on the slider to move synchronously and cut at the same time. Rotating the adjusting screw can drive the cutting knife to move up and down to change the cutting position, which is convenient for adjustment.

[0019] The above-mentioned light box cloth processing and cutting device also includes telescopic rods, and the number of the telescopic rods is several, and the several telescopic rods are connected between the horizontal frame and the movable plate.

[0020] The telescopic rod can be stably extended and retracted, and can play a certain guiding role, so that when the adjusting screw is rotated, the upward and downward movement of the moving plate is driven to be more stable.

[0021] Compared with the prior art, the light box cloth processing and cutting device of the present invention creatively arranges a frame, a flattening plate, a positioning member, an adjusting member, a driving member and a cutting knife. The end cross-section of the flattening plate is a combination of a circle and an equilateral triangle, that is, an inverted water drop shape. The flattening plate is hinged to the frame with the center of the end circle as the hinge point. When the flattening plate is against the light box cloth, the circumferential position of the flattening plate can be adjusted and positioned by the positioning member. The angle of the flattening plate can be adjusted for light box cloths of different thicknesses, thereby increasing the flatness of the cut light box cloth, making it less likely to produce tilting and wrinkles, and improving the stretching stability when cutting the light box cloth.

[0022] The light box cloth first passes through the flat plate and then passes under the driving member. When the light box cloth is being processed and cut, the upper and lower positions of the cutting knife connected to the driving member can be changed through the adjusting member, which is convenient to operate and improves the applicability of the device.
