Description

Technical Field

[0001] This utility model belongs to the field of paper bowl production technology, and specifically relates to a paper bowl forming device. Background Technology

[0002] A paper bowl forming device is a mechanical device specifically designed to process flat paper or cardboard materials into disposable paper bowls. This device typically includes a feeding system, forming molds, a heating system (for thermoforming), a cutting system, and an output system. Its main function is to transform flat paper material into paper bowls of specific shapes and sizes through a series of automated steps, such as cutting, forming, pressing, and trimming. Die-cutting of the cardboard is an essential step in paper bowl forming.

[0003] Existing paper bowl forming devices use a die-cutting machine to push the paper stack downwards with a die-cutting mold, cutting out the basic outline of the paper bowl according to the shape of the mold, thus achieving the initial forming of the paper bowl. However, the paper stack after die-cutting remains inside the die-cutting mold, and manual or mechanical cleaning is required after each die-cutting, which increases non-processing time and lengthens each die-cutting cycle, thereby reducing the output per unit time. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a paper bowl forming device that can eject the die-cut paper bowl stacks from inside the die-cutting mold and collect the material, allowing it to be quickly transferred to the next forming equipment, reducing non-production time and improving the overall efficiency of the paper bowl production line.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a paper bowl forming device, including a support plate, a plurality of guide columns are provided at the upper end of the support plate, the support plate and the guide columns are fixed by welding, a die-cutting plate corresponding to the position of the mating groove opened inside the support plate is slidably arranged between the plurality of guide columns, a slide rail is provided on the rear side of the support plate, the support plate and the slide rail are fixed by welding, a receiving box is slidably arranged inside the slide rail, a pusher plate is slidably arranged inside the receiving box, a first driving mechanism for driving the pusher plate to move is provided at the lower end of the receiving box, and a second driving mechanism for driving the receiving box to move is provided inside the slide rail.

[0006] Drive mechanism one includes a connecting plate located at the lower end of the receiving box, a lead screw one rotatably mounted inside the connecting plate, a pusher plate threadedly connected to lead screw one, a motor one located at the rear side of the connecting plate, and the output shaft of motor one connected to the rear end of lead screw one via a coupling. Drive mechanism two includes a lead screw two rotatably mounted inside a slide rail, the lower end of the receiving box threadedly connected to lead screw two, a motor two located at the rear side of the slide rail, and the output shaft of motor two connected to the rear end of lead screw two via a coupling.

[0007] As a further improvement of this utility model, mounting frame plates are respectively provided on the left and right sides of the bearing plate. The bearing plate and the mounting frame plates are fixed by welding. A sliding column is slidably provided inside each mounting frame plate. A fixing plate is provided on the inner end of each of the two sliding columns. An electric push rod is provided inside each of the two mounting frame plates. The telescopic ends of the two electric push rods are respectively connected to the outer side of the adjacent fixing plate. The left and right positions of the two fixing plates correspond.

[0008] As a further improvement of this utility model, a support frame is provided at the lower end of the bearing plate, and a collection box is placed inside the support frame.

[0009] As a further improvement of this utility model, a rectangular plate is provided between the upper ends of the guide pillars, and a hydraulic push rod is provided at the upper end of the rectangular plate. The telescopic end of the hydraulic push rod is connected to the upper end of the die-cutting plate. Multiple top pillars are provided at the lower end of the rectangular plate, and through holes corresponding to the upper and lower positions of the top pillars are opened inside the die-cutting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, by controlling the operation of the electric push rod, the telescopic end drives the fixed plates on both sides to move closer together under the restriction of the sliding column to clamp and fix the cardboard stack. Then, the operation of the electric push rod is turned off. Subsequently, by controlling the operation of the hydraulic push rod, the telescopic end drives the die-cutting plate to move downward under the restriction of the guide column and contact the cardboard stack, which can quickly cut the cardboard stack into paper cupboards.

[0012] Secondly, by controlling the second motor to rotate forward, the receiving box moves forward to the lower end of the die-cutting plate, and then the second motor is turned off. The die-cutting plate continues to move upward under the drive of the hydraulic push rod. The push rod inserts into the inside of the round hole of the die-cutting plate, pushing the paper cupboard inside the die-cutting plate mold out and letting it fall into the receiving box. Then, by controlling the second motor to rotate in reverse, the paper cupboard inside the receiving box moves backward. By controlling the first motor to run, the pusher plate moves backward and pushes the paper cupboard inside the receiving box onto the receiving platform of the next production process. This can push the stack of die-cut paper cupboards out from inside the die-cutting mold and collect them for discharge, allowing them to be quickly transferred to the next forming equipment, reducing non-production time and improving the overall efficiency of the paper cup production line.

[0013] Thirdly, when die-cutting cardboard stacks, some of the cardboard cupboards that do not remain inside the die-cutting mold can fall into the collection box for collection, thus fully realizing the collection of cardboard cupboards. Attached Figure Description
