Description

Technical Field

[0001] This utility model relates to a slitting machine for coating the surface of paper cups. Background Technology

[0002] In the paper cup production process, the paper cups need to be laminated. Before lamination, the large roll of film needs to be cut to match the size of the paper cups.

[0003] Existing slitting operations typically involve adjusting the film during the slitting process using simple sensors. When a small deviation occurs, it can be adjusted using a guide roller. However, when the deviation is large, the guide roller cannot adjust quickly, which can easily lead to a larger range of deviations or even roller slippage. Utility Model Content

[0004] This invention provides a slitting machine for coating the surface of paper cups.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a slitting machine for coating the surface of paper cups, including a support, a cutter, a drive mechanism and a detection mechanism, wherein the drive mechanism is arranged above the support, the cutter and the detection mechanism are arranged inside the support, and the cutter is connected to the drive mechanism in a transmission manner;

[0006] The support includes a horizontal beam and two vertical columns. The horizontal beam is set horizontally, and the two vertical columns are set vertically at both ends of the horizontal beam.

[0007] The drive mechanism includes a cylinder and a push rod. The push rod is arranged vertically, and the cylinder is arranged horizontally on the crossbeam. The push rod is connected to the top of the cylinder rod. The crossbeam has a strip hole parallel to the crossbeam. The tip of the cutter is arranged vertically downward. The tail of the cutter passes through the strip hole of the crossbeam and is connected to the lower end of the push rod.

[0008] A sliding rod is provided below the crossbeam, the sliding rod is connected to the cutter, the length of the sliding rod is less than the length of the crossbeam, and a guide rod is provided at each end of the sliding rod, the guide rod passing through the column;

[0009] A limiting block is provided at the end of the guide rod away from the slide rod;

[0010] A guide block is provided between the limiting block and the column, the guide block is fixed below the crossbeam, and the guide rod passes through the guide block;

[0011] The detection mechanism includes two detection units, which are respectively set at both ends of the slide rod. Each detection unit includes a fixed column, a pressure sensor, and a laser sensor. The fixed column is vertically arranged, and its upper end is connected to the slide rod. The pressure sensor and the laser sensor are both set on the same side of the fixed column. The distance between the two pressure sensors of the two detection units is greater than the distance between the two laser sensors of the two detection units.

[0012] Preferably, the crossbeam has grooves on both sides of the slot, and the push rod has a roller on each side. The two rollers are located in the two grooves respectively, and the rollers are in rolling connection with the grooves.

[0013] Preferably, the laser sensors of the two detection units are symmetrical about the cutter, and the pressure sensors of the two detection units are symmetrical about the cutter.

[0014] The beneficial effects of this utility model are that the slitting machine for coating the surface of paper cups uses two laser sensors for detection. When a slight deviation occurs, the cutting position of the cutter is corrected in time by controlling the cylinder. When a large deviation occurs and cannot be adjusted in time, the pressure sensor is subjected to pressure, which will cause the whole machine to stop suddenly, reducing the probability of large-scale deviation and reducing maintenance difficulty.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1-3As shown, a slitting machine for coating the surface of paper cups includes a support, a cutter 5, a drive mechanism, and a detection mechanism. The drive mechanism is disposed above the support, and the cutter 5 and the detection mechanism are disposed inside the support. The cutter 5 is connected to the drive mechanism in a transmission manner.

[0022] The support includes a horizontal beam 1 and two vertical columns 2. The horizontal beam 1 is set horizontally, and the two vertical columns 2 are set vertically at both ends of the horizontal beam 1.

[0023] The drive mechanism includes a cylinder 3 and a push rod 4. The push rod 4 is arranged vertically, and the cylinder 3 is arranged horizontally on the crossbeam 1. The push rod 4 is connected to the top of the cylinder rod of the cylinder 3. The crossbeam 1 has a strip hole parallel to the crossbeam 1. The tip of the cutter 5 is arranged vertically downward. The tail of the cutter 5 passes through the strip hole of the crossbeam 1 and is connected to the lower end of the push rod 4.

[0024] A sliding rod 6 is provided below the crossbeam 1. The sliding rod 6 is connected to the cutter 5. The length of the sliding rod 6 is less than the length of the crossbeam 1. A guide rod 7 is provided at each end of the sliding rod 6. The guide rod 7 passes through the column 2.

[0025] The guide rod 7 is provided with a limiting block 9 at the end away from the slide rod 6;

[0026] A guide block 8 is provided between the limiting block 9 and the column 2. The guide block 8 is fixed below the crossbeam 1, and the guide rod 7 passes through the guide block 8.

[0027] The detection mechanism includes two detection units, which are respectively set at both ends of the slide rod 6. Each detection unit includes a fixed column 10, a pressure sensor 12, and a laser sensor 11. The fixed column 10 is vertically arranged, and its upper end is connected to the slide rod 6. The pressure sensor 12 and the laser sensor 11 are both set on the same side of the fixed column 10. The distance between the two pressure sensors 12 of the two detection units is greater than the distance between the two laser sensors 11 of the two detection units.

[0028] Preferably, the crossbeam 1 has grooves 13 on both sides of the strip hole, and the push rod 4 has a roller 14 on each side. The two rollers 14 are located in the two grooves 13 respectively, and the rollers 14 are tactilely connected to the grooves 13.

[0029] Preferably, the laser sensors 11 of the two detection units are symmetrical about the cutter 5, and the pressure sensors 12 of the two detection units are symmetrical about the cutter 5.

[0030] In fact, cylinder 3, laser sensor 11 and pressure sensor 12 are all connected to PLC, and the PLC controls the actions and processes the data.

[0031] During normal operation, the cutter 5 cuts the film, and two laser sensors 11 detect the boundaries of the film. When the film has a small displacement deviation, the laser sensors 11 will detect it and control the cylinder 3 to push the push rod 4 to move, thereby driving the cutter 5 to adjust its position. When the film has a large deviation and the edge of the film touches the pressure sensor 12, the entire machine will stop suddenly to prevent the deviation from expanding further and reduce maintenance difficulty.

[0032] Compared with existing technologies, this slitting machine for coating paper cups uses two laser sensors 11 for detection. When a small deviation occurs, the cutting position of the cutter 5 is corrected in time by controlling the cylinder 3. When a large deviation occurs and cannot be adjusted in time, the pressure sensor 12 is subjected to pressure, which will cause the whole machine to stop suddenly, reducing the probability of large-scale deviations and reducing maintenance difficulty.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
