Description

Technical Field

[0001] This utility model relates to the field of paper cup preparation technology, and in particular to a paper cutting device for preparing environmentally friendly plastic-free paper cups. Background Technology

[0002] Environmentally friendly plastic-free paper cups use FSC-certified sustainable forest pulp as the base paper, replacing traditional polyethylene (PE) or paraffin coating. Instead, they use plant-based biodegradable materials such as polylactic acid (PLA), starch-based coatings, or natural beeswax, achieving a completely plastic-free process. These materials can be degraded into water and carbon dioxide through composting, solving the recycling problem of traditional paper cups where "paper and plastic are difficult to separate".

[0003] In our daily work, we have found that the production process of existing environmentally friendly plastic-free paper cups often involves the use of cutting devices to cut the rolled paper cups into individual pieces for subsequent processing. However, the current method of cutting involves directly controlling the blade to move up and down, which makes it difficult to ensure the stability of the paper cups during the cutting process. This can easily lead to errors in the cutting process, resulting in a series of problems such as cutting mistakes and uneven edges, which seriously affect the quality of paper cup production. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that it is difficult to ensure the stability of the paper cup during cutting, which affects the cutting quality, and to propose an environmentally friendly paper cutting device for preparing plastic-free paper cups.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly paper cutting device for preparing plastic-free paper cups, comprising a base, an upper seat above the base, two cylinders (first type) fixedly connected to the two side surfaces of the base respectively, the output ends of multiple cylinders (first type) fixedly connected to the surface of the upper seat, two guide members slidably connected to the inner wall of the base, two through holes opened on the surfaces of both the base and the upper seat for the guide members to pass through, a driving part for moving the guide members is provided on the base, a bracket is fixedly connected to the surface of the upper seat, two cylinders (second type) fixedly connected to the bracket, a blade body fixedly connected to the output end of the cylinders (second type), and a plate body fixedly connected to one side surface of the base. Through the above components, when cutting paper cups, as the paper cups pass between the base and the upper seat, the guide members can guide the paper cups. During cutting, cylinders (first type) drive the upper seat to fit against the base, clamping the paper cups. Subsequently, cylinders (second type) drive the blade body to move, and the blade body, in conjunction with the plate body, performs the cutting operation on the paper cups, achieving stable cutting and improving the cutting effect.

[0006] Preferably, the driving unit includes a bidirectional screw rotatably connected to the inner wall of the base. The bidirectional screw is threadedly connected to the inner walls of two guide members. A drive motor is fixedly connected to one side surface of the base. The output end of the drive motor is fixedly connected to one end of the bidirectional screw. By using the above components, the drive motor can be turned on, and the drive motor can control the bidirectional screw to rotate. The bidirectional screw controls the two guide members to move in the base and adjust their positions to accommodate paper cups of different sizes.

[0007] Preferably, a scale block is fixedly connected to the surface of the guide member, and a scale is provided on the surface of the base near the scale block. Through the above components, the guide member can drive the scale block to move when it moves, and the adjustment accuracy can be improved by cooperating with the scale.

[0008] Preferably, the guide includes a slide block that is slidably connected to the inner wall of the base. Two rods are fixedly connected to the slide block, and guide wheels are rotatably connected to the surface of the rods. Through the above components, the guide can intercept the side of the paper cup through the two guide wheels, thereby improving the stability during conveying and facilitating cutting.

[0009] Preferably, a pad one is fixedly connected to the surface of the base, and a pad two is fixedly connected to the surface of the upper seat. With the above components, when the base and the upper seat are in contact to hold the paper cup, the pad one and the pad two can protect the paper cup and reduce the damage to the paper cup.

[0010] Preferably, both pad one and pad two are made of rubber.

[0011] Preferably, two guide rods are fixedly connected to the surface of the blade body, and the guide rods are slidably connected to the inner wall of the bracket. Through the above-mentioned components, the two guide rods can improve the stability of the blade body when it moves.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the two guide members are controlled by the drive unit to slide on the base, thereby guiding and intercepting the paper cup. During cutting, the first cylinder can drive the upper seat to fit against the base to clamp the paper cup, reducing paper displacement or warping during cutting. This allows the second cylinder to work with the blade and plate to cut the paperboard, effectively improving cutting accuracy, ensuring a flat cut and consistent size, and enhancing overall practicality.

[0014] In this invention, when the guide component moves, it can drive the scale block to move as well. The scale block, in conjunction with the scale, facilitates adjustment and observation, thereby improving the accuracy of adjustment.

[0015] In this invention, when cylinder one drives the upper seat to fit against the base, the base and the upper seat contact the paper through pad one and pad two, resulting in uniform and gentle pressure and reducing the phenomenon of paper being pinched or damaged. Attached Figure Description

Two cylinders 5 are fixedly connected to the bracket 4. A blade 6 is fixedly connected to the output end of the cylinder 5. A plate 10 is fixedly connected to one side surface of the base 1. Two guide rods 7 are fixedly connected to the surface of the blade 6. The guide rods 7 are slidably connected to the inner wall of the bracket 4. The drive unit 13 includes a bidirectional screw 132 that is rotatably connected to the inner wall of the base 1. The bidirectional screw 132 is threadedly connected to the inner wall of the two guide members 8. A drive motor 131 is fixedly connected to one side surface of the base 1. The output end of the drive motor 131 is fixedly connected to one end of the bidirectional screw 132.

[0024] In this implementation scheme: When cutting paper cups, as the paper cup passes between the base 1 and the upper seat 2, the drive motor 131 is turned on. The drive motor 131 controls the bidirectional screw 132 to rotate. The bidirectional screw 132 controls the two guide members 8 to move in the base 1 and adjust their positions to accommodate paper cups of different sizes. The guide members 8 can guide the paper cup. During cutting, the cylinder 1 3 drives the upper seat 2 to fit against the base 1, clamping the paper cup. Then, the cylinder 2 5 drives the blade 6 to move. The blade 6, in conjunction with the plate 10, performs the cutting operation on the paper cup, achieving stable cutting and improving the cutting effect.

[0025] Specifically, a scale block 15 is fixedly connected to the surface of the guide component 8, and a scale 14 is provided on the surface of the base 1 near the scale block 15. When the guide component 8 moves, it can drive the scale block 15 to move, and the scale 14 can improve the adjustment accuracy.

[0026] Specifically, the guide member 8 includes a slide 81 that is slidably connected to the inner wall of the base 1. Two rods 82 are fixedly connected to the slide 81, and guide wheels 83 are rotatably connected to the surface of the rods 82.

[0027] In this implementation scheme: the guide member 8 can intercept the side of the paper cup through two guide wheels 83, which improves the stability during conveying and facilitates cutting.

[0028] Specifically, a pad 11 is fixedly connected to the surface of the base 1, and a pad 2 is fixedly connected to the surface of the upper seat 2. Both pad 11 and pad 2 are made of rubber.

[0029] In this implementation plan: when the base 1 and the upper seat 2 are attached and clamp the paper cup, the pad 1 11 and the pad 2 12 can protect the paper cup and reduce the damage to the paper cup.

[0030] Working principle: When working, first turn on the drive motor 131. The drive motor 131 can control the bidirectional screw 132 to rotate. The bidirectional screw 132 controls the two guide members 8 to move in the base 1. At the same time, the guide members 8 drive the scale block 15 to move together. With the help of the scale 14, the position can be adjusted to accommodate paper cups of different sizes. The guide members 8 can guide the paper cups passing between the upper seat 2 and the base 1. When cutting is required, turn on the cylinder 3. The cylinder 3 drives the upper seat 2 to move closer to the base 1. The guide wheel 83 in the guide member 8 passes through the perforation 9 on the surface of the upper seat 2. The upper seat 2 and the base 1, with the help of the pad block 2 12 and the pad block 11, can clamp the paper cups. After clamping, the cylinder 2 5 drives the cutter body 6 to move. The cutter body 6, with the help of the plate body 10, can cut the paper cups.
