Description

Technical Field

[0001] This utility model relates to the technical field of packaging bag cutting, and in particular to an environmentally friendly plastic flexible packaging tote bag cutting device. Background Technology

[0002] Eco-friendly plastic flexible packaging tote bags are soft tote bags made of biodegradable, recyclable or reusable materials. Their core advantage lies in reducing pollution from traditional plastics while taking into account practicality and economy. The production process requires the product to be cut and processed.

[0003] The existing Chinese utility model patent with application number CN202222395382.5 relates to a paper packaging bag cutting production device, including a workbench, a mounting groove, a trapezoidal groove, a mounting mechanism, a transmission roller, a motor, and a mounting frame, etc. It can fix and cut paper patterns, improving the cutting effect. The cut paper patterns fall into the collection box through the trapezoidal groove, making it convenient to collect paper patterns and easy to use.

[0004] However, in actual use, the aforementioned device does not have the ability to continuously convey materials in packaging bags, which affects the equipment's production efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly plastic flexible packaging tote bag cutting device that uses a conveying device to transport unseparated packaging tote bag raw materials, a cutting device to cut the packaging tote bags, and a carrying device to support the cutting position, thereby reducing the damage caused by the cutting device to the conveying device and improving the practicality of the device.

[0006] This utility model discloses an environmentally friendly plastic flexible packaging tote bag cutting device; it includes a conveying device, a cutting device, and a carrying device. The cutting device is installed on the conveying device, and the carrying device is installed on the conveying device. The conveying device transports the unseparated packaging tote bag raw materials, the cutting device cuts the packaging tote bags, and the carrying device supports the cutting position, thereby reducing the damage caused by the cutting device to the conveying device and improving the practicality of the device.

[0007] Preferably, the conveying device includes a frame, conveyor rollers, a conveyor belt, a reducer, a drive motor, and guide rollers. Multiple sets of conveyor rollers are horizontally mounted on the frame, and the conveyor belt is fitted onto the multiple sets of conveyor rollers. A reducer is mounted on the side of the frame and connected to the outermost conveyor roller. A drive motor is mounted on the reducer, and a guide roller is mounted on the right side of the frame. When the drive motor is turned on, power is transmitted through the reducer to the conveyor rollers connected to it, thereby driving the conveyor rollers to rotate. The continuous packaging bags that have not been broken are transported by the conveyor belt and the multiple sets of conveyor rollers. The guide rollers guide the packaging bags, so that the packaging bags are in full contact with the surface of the conveyor belt, allowing the packaging bags to stick to the upper surface of the conveyor belt, reducing wrinkles, facilitating the cutting operation, and improving the practicality of the device.

[0008] Preferably, the slitting device includes a gantry, an electric cylinder, a blade holder, a cutting blade, and fixing bolts. The gantry is installed on the upper left side of the frame, and the electric cylinder is installed on the upper surface of the gantry. The moving end of the electric cylinder extends through the upper surface of the gantry to the lower side of the gantry and connects with the blade holder. The cutting blade is installed on the lower part of the blade holder by fixing bolts. By controlling the extension of the electric cylinder, the blade holder is lowered, so that the cutting blade on the blade holder moves the packaging bag to the cutting area, thus completing the slitting operation of the packaging bag. The blade holder and the cutting blade are connected and fixed by fixing bolts, which facilitates the operator to replace and clean the cutting blade, improving the practicality of the device.

[0009] Preferably, the device also includes limiting rods and linear bearings. A set of limiting rods is provided at the front and rear of the upper end of the tool holder, and a set of linear bearings is provided on the gantry at the positions corresponding to the two sets of limiting rods. The limiting rods extend to the upper side of the gantry through the linear bearings. The limiting rods and linear bearings assist in limiting the lifting and lowering process of the tool holder, reducing the sway amplitude of the tool holder during the lifting and lowering process, and improving the stability and practicality of the device.

[0010] Preferably, it also includes a pressure sensor, and the moving end of the electric cylinder is connected to the upper end face of the cutter holder through the pressure sensor; the pressure sensor detects the pressure on the moving end of the electric cylinder to prevent excessive pressure from damaging the equipment during the cutting process, thereby improving the practicality of the device.

[0011] Preferably, the bearing device includes a U-shaped groove, a metal support bar, a limiting groove, a limiting protrusion, and a limiting bolt. Multiple sets of U-shaped grooves are evenly arranged on the bearing surface of the conveyor belt, with the interval between the sets of U-shaped grooves being the same as the cutting interval between the packaging bags. A limiting groove is provided on each of the lower two sides of the U-shaped groove. The metal support bar is placed in the U-shaped groove, and a limiting protrusion is provided on the lower left and right sides of the metal support bar. A set of threaded holes is provided on the front and rear end faces of the limiting protrusions, and a limiting bolt is installed on the threaded holes of the limiting protrusions. The end of the limiting bolt... The head covers the side of the conveyor belt; the front and rear positions of the metal support bar in the U-shaped groove are limited by the limiting bolts to prevent the metal support bar from moving back and forth in the U-shaped groove. The limiting protrusion and the limiting groove prevent the metal support bar from falling off naturally when it rotates to the lower side. The size of the limiting groove itself ensures that the limiting protrusion will not come out of the limiting groove when the U-shaped groove rotates with the conveyor belt on the side conveyor roller. The metal support bar provides support for the cutting area and prevents the cutting blade from scratching the bearing surface of the conveyor belt during the cutting process, thus improving the practicality of the device.

[0012] Preferably, the device also includes a motor and a cleaning roller. The cleaning roller is installed in the lower part of the frame, and the motor is installed on the side of the frame. The output end of the motor is connected to the cleaning roller, and the upper part of the cleaning roller is close to the lower end face of the conveyor belt. When the motor is turned on, the power is transmitted to the cleaning roller to drive the cleaning roller to rotate. The rotating cleaning roller cleans the conveyor belt bearing surface, reducing the impact of debris on the conveyor belt bearing surface on the cutting process and improving the practicality of the device.

[0013] Preferably, the device also includes a support frame and fans. The support frame is installed on the lower left side of the frame, and multiple fans are installed on the right end face of the support frame. After the multiple fans are turned on, the air is pressurized and output from the left side of the support frame, thereby blowing off the plastic bags that have been cut and are attached to the surface of the conveyor belt, which improves the practicality of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the unseparated packaging bag raw materials are transported by the conveying device, the packaging bag is cut by the cutting device, and the cutting position is supported by the bearing device, which reduces the damage caused by the cutting device to the conveying device and improves the practicality of the device.
