Description

Technical Field

[0001] The utility model relates to the technical field of paper cup base shearing, in particular to a paper cup base shearing and forming device. Background Art

[0002] Paper cups are made of paper made of chemical wood pulp through mechanical processing and bonding. They are cup-shaped. Paper cups for frozen food are coated with wax, and paper cups for hot drinks are coated with plastic. They are resistant to high temperatures and can even hold boiling water. When producing paper cups, the paper needs to be cut into appropriate sizes and then bonded.

[0003] The existing paper cutting device has a complex fixing structure during cutting and is inconvenient to operate, which causes cutting deviation due to shaking during cutting, resulting in paper waste.

[0004] For example, a paper cutting device for paper cup processing disclosed in Chinese patent CN219381770U is provided with a clamping assembly, which includes a transverse plate, a screw, a spring coil and a pressure plate, and the transverse plate is slidably connected to the surface of the slide rail. When the paper needs to be fixed, the transverse plate is slid to move on the upper surface of the slide rail, and the screw is pulled up at the same time. When the screw moves up, it drives the pressure plate to squeeze the spring coil, and then the screw is loosened. Under the action of the spring coil, the pressure plate and the paper on the upper surface of the base are in contact with each other and the paper is fixed tightly, thereby avoiding the problem of paper shaking.

[0005] However, the cutting device is not convenient for cutting paper into a circular shape, and thus is not convenient for cutting a circular paper cup base.

[0006] For this reason, we urgently need to provide a paper cup base shearing and forming device that can shear a circular base. Utility Model Content

[0007] The utility model aims to provide a paper cup base shearing and forming device to solve the problem that the cutting device proposed in the above background technology is not convenient for cutting paper into a circle, and thus is not convenient for cutting a circular paper cup base.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paper cup base shearing and forming device, comprising a base plate and a fixing frame, wherein the fixing frame is fixedly connected to the middle position of the upper side of the base plate, and the outer end of the base plate is connected to a shearing mechanism, wherein the shearing mechanism comprises a shearing unit and a pressing unit, wherein the shearing unit is arranged at the middle position of the upper end of the base plate, and the pressing unit is arranged at the left and right ends above the base plate.

[0009] The shearing unit includes a motor, a rotating rod, a sleeve rod, a sliding rod, a spring, an insertion rod, a bearing, a round rod and a circular cutting blade. The motor is fixedly connected to the upper middle position of the fixed frame, the rotating rod is fixedly connected to the lower end of the output shaft of the motor, the sleeve rod is fixedly connected to the outer side of the lower end of the rotating rod, the sliding rod is slidably connected to the inner side of the sleeve rod, the spring is connected to the inside of the sliding rod, the insertion rod is fixedly connected to the upper end of the spring, the bearing is fixedly connected to the inner middle position of the right end of the sliding rod, the round rod is fixedly connected to the inner side of the bearing, and the circular cutting blade is connected to the right end of the round rod.

[0010] A further improvement is that a circular groove is provided at the middle position above the left end of the sliding rod, and insertion holes are provided at equal distances above the inner part of the sleeve rod, the lower end of the spring is fixedly connected to the inner bottom end of the circular groove, and the outer side of the upper end of the insertion rod is plugged into the inner side of the insertion hole. Thus, after the sliding rod is slid along the inner side of the sleeve rod to move the circular cutting piece at the right end to a suitable position, the insertion rod is pushed up by the spring rebound to push the upper end of the insertion rod into the insertion hole at the corresponding position of the upper end of the sleeve rod, so that the sliding rod can be fixed to the inner side of the sleeve rod.

[0011] A further improvement is that a thread groove is provided in the middle of the right end of the round rod, and a round hole is provided in the middle of the round cutting disc. Thus, the round cutting disc can be fixed to the right end of the round rod by passing a bolt through the round hole and then threading it into the thread groove. When the round cutting disc needs to be removed, the bolt only needs to be removed from the right end of the round rod to remove the round cutting disc from the right end of the round rod.

[0012] A further improvement is that the clamping unit includes a sliding block, a movable frame, a threaded rod, a rotating handle and a pressure plate, the sliding block is connected to the front and rear ends of the bottom plate, the movable frame is fixedly connected to the outside of the sliding block, the threaded rod is connected to the upper end of the interior of the movable frame, the rotating handle is fixedly connected to the upper end of the threaded rod, and the pressure plate is fixedly connected to the lower end of the threaded rod.

[0013] A further improvement is that threaded holes are provided at the front and rear ends of the upper part of the interior of the mobile frame, and sliding grooves are symmetrically provided at the front and rear sides of the interior of the bottom plate, the outer side of the sliding block is slidably connected to the inner side of the sliding groove, and the outer side of the threaded rod is threadedly connected to the inner side of the threaded hole. Thus, when the rotating handle is turned to drive the threaded rod in the threaded hole to rotate, the threaded rod can move relative to the mobile frame, thereby driving the pressure plate to move together.

[0014] A further improvement is that the lower side of the pressure plate abuts against the upper side of the paper on the bottom plate. Thus, after placing the paper to be cut on the upper side of the bottom plate, the rotating handle is turned to drive the threaded rod to rotate so that the pressure plate moves down to the upper end of the paper, and the paper can be fixed to the upper end of the bottom plate, ensuring that the paper remains fixed while cutting, preventing deviation in cutting.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower side of the pressing plate, so that when the pressing plate is moved to the upper side of the paper on the bottom plate to press the paper, the rubber pad on the lower side of the pressing plate contacts the upper side of the paper, so that the paper can be fixed more firmly.

[0016] In summary, the present application discloses a paper cup base shearing and forming device.

[0017] The technical solution starts the motor and its output shaft rotates the rotating rod at the lower end, so that when the sleeve rod and the sliding rod rotate together, the circular cutting piece will rotate on the paper on the bottom plate, cutting a complete circular base from the center of the paper.

[0018] Furthermore, after placing the paper to be cut on the upper side of the bottom plate, the rotating handle is turned to drive the threaded rod to rotate so that the pressure plate moves down to the upper end of the paper, so that the paper can be fixed to the upper end of the bottom plate, ensuring that the paper remains fixed while cutting to prevent cutting deviation.
