Description

Technical Field

[0001] The utility model relates to the field of shearing devices, in particular to a paper straw fixed-distance shearing device. Background Art

[0002] Paper straws are small straws made of paper, usually used for packaging or decoration of beverages, food, etc. In order to ensure the quality and precision of paper straws, paper straws need to be cut into specific lengths and shapes during the production process for use in packaging or decoration. The existing shearing device uses a cutter to cut the material during the paper straw cutting process. Since it is difficult to cut multiple paper straws at the same time, the cutting distance is not easy to adjust, so that multiple cuttings are required to complete the required number of straws, resulting in a decrease in production efficiency. Therefore, we proposed a paper straw fixed-distance cutting device to solve the above problems. Utility Model Content

[0003] In order to overcome the problem of using a cutter to cut the material during the paper straw cutting process, since it is difficult to cut multiple paper straws at the same time and the cutting distance is not easy to adjust, multiple cuts are required to complete the required number of straws, resulting in reduced production efficiency.

[0004] The technical solution of the utility model is: a paper straw spacing cutting device, including a tank body, a guide tube, a funnel, a spacing assembly and a cutting assembly. A spacing assembly for aligning paper straws is installed at the outer end of the tank body, a guide tube is provided at the rear of the tank body, a cutting assembly for cutting paper straws is installed between the tank body and the guide tube, and a funnel for facilitating the rolling out of the paper straws is provided at the end of the tank body away from the guide tube.

[0005] Preferably, the staff first places multiple groups of straws from the guide ring into the tank body, pushes the top inward, starts the telescopic push rod, the telescopic push rod pushes the stretching arm, and the multiple groups of stretching arms rotate to drive the distance plate to flatten the tank body. The ends of the multiple groups of paper straws are flattened by the distance plate, and the driver is started to drive the rotating ring to rotate. The multiple groups of rotating rings drive the blade to rotate to cut the paper straws. Compared with vertical cutting by the blade, rotary cutting by the blade can provide a smoother cut surface during the cutting process and reduce cutting errors, thereby obtaining more precise dimensions and better cutting quality. After cutting is completed, the blade is reset and retracted. The telescopic push rod lifts the distance plate, and the cut paper straws are pushed out by the rear end paper straws. Multiple groups of paper straws can be cut at the same time, which can greatly improve production efficiency, reduce production time and cost, shorten the production cycle, and aligning paper straws can reduce waste caused by the end straws. When the length of the cut paper straws needs to be changed, loosen the adjustment rings on both sides of the blade, push the rotating ring on the connecting column to the required length, and then tighten the adjustment ring to change the cutting length. The length of the straw can be flexibly changed as needed to adapt to different usage scenarios and needs. This can increase the versatility and applicability of the straws.

[0006] Preferably, the distance assembly includes a distance plate, a stretching arm, a telescopic push rod, a first movable sleeve, a fixed rod, a movable shaft, a second movable sleeve and a mounting ring.

The interior of the first movable sleeve is provided with a telescopic push rod. The telescopic push rod and the first movable sleeve are movably connected through a rotating ring. When the first movable sleeve is pushed, the telescopic push rod is driven to move in the first movable sleeve, so that the telescopic push rod can change its angle, and the telescopic push rod can drive the distance plate inward for a certain distance.

[0007] Preferably, the end of the telescopic push rod away from the first movable sleeve is movably connected with a stretching arm. There are three groups of stretching arms.

A second movable sleeve is provided on the outer side of the fixed rod. The fixed rod is movably connected to the tank body through the second movable sleeve. The telescopic push rod pushes the stretching arm, and multiple groups of stretching arms rotate to drive the distance plate to flatten the ends into the tank body. The ends of multiple groups of paper straws are flattened by the distance plate to prevent the ends from being unable to be aligned and resulting in waste of material. The position of each paper straw during cutting can be more stable, reducing errors and waste.

[0008] Preferably, the cutting assembly includes a fixed ring, a connecting column, a rotating ring, a blade and an adjustment ring. There are two groups of fixed rings. The two groups of fixed rings are arranged adjacent to each other. Multiple groups of connecting columns are fixed between the two groups of fixed rings. The multiple groups of connecting columns are arranged around the multiple groups of fixed rings. By setting up multiple groups of connecting columns, multiple groups of blades can be installed, so that multiple groups of straws inside can be cut at the same time, avoiding too few blades, which will result in some straws not being cut.

[0009] Preferably, a rotating ring is provided on the outside of the fixed ring, a blade for cutting is provided on the outside of the rotating ring, and a driver is provided inside the rotating ring. The driver drives the rotating ring to drive the blade for rotational shearing.

[0010] Preferably, adjustment rings for adjusting the cutting position of the cutter are provided on both sides of the rotating ring, and the connection between the adjusting ring and the connecting column is covered with a rubber layer for preventing the adjusting ring from slipping. When the length of the cut paper straw needs to be changed, the adjustment rings on both sides of the blade are loosened, the rotating ring is pushed on the connecting column to the required length, and then the adjusting ring is tightened, so that the cutting length can be changed, and the length of the straw can be flexibly changed as needed.

[0011] Preferably, the lower end of the tank body is provided with supporting legs for supporting the device. The supporting legs are provided with multiple groups, and the multiple groups of supporting legs are evenly distributed at the lower end of the tank body. The supporting legs can be changed in height.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional method of cutting materials with a cutting knife, it is difficult to cut multiple paper straws at the same time, and the cutting distance is not easy to adjust, so that multiple cuts are required to complete the required number of straws, resulting in reduced production efficiency. A tank body that can cut multiple groups of paper straws at the same time is added, and the distance component aligns the ends of multiple groups of straws to prevent different cutting lengths. It is better than the existing cutting device and is suitable for cutting paper straws. The staff first places the multiple groups of straws inside the tank body from the guide ring, pushes inward, and starts the telescopic push rod. The telescopic push rod pushes the stretching arm, and the stretching arm rotates multiple groups to drive the distance plate to flatten the ends of the multiple groups of paper straws into the tank body. The ends of the multiple groups of paper straws are flattened by the distance plate, and the drive is started to drive the rotating ring to rotate. Multiple groups of rotating rings drive the blade to rotate to cut the paper straws. The blade rotation cutting is compared to the blade Vertical cutting and rotating blade cutting can provide a smoother cross section during the cutting process and reduce cutting errors, thereby obtaining more precise size and better cutting quality. After cutting is completed, the blade is reset, the telescopic push rod is retracted, the distance plate is lifted, and the rear end paper straw pushes out the cut paper straws. Multiple groups of paper straws are cut at the same time, which can greatly improve production efficiency, which can reduce production time and cost, shorten the production cycle, and aligning paper straws can reduce waste caused by the end straws. When the length of the cut paper straws needs to change, loosen the adjustment rings on both sides of the blade, push the rotating ring on the connecting column to the required length, and then tighten the adjustment ring to change the cutting length. The length of the straw can be flexibly changed as needed to adapt to different usage scenarios and needs. This can increase the versatility and applicability of the straws.

[0014] 2. The spacing component uses spacing plates to align the ends of the paper straws inside the can to prevent the ends from being misaligned and resulting in waste of material. This can make the position of each paper straw more stable during cutting, reduce errors and waste. The beneficial effect of aligning and cutting multiple groups of paper straws at the same time is that it can improve cutting efficiency and accuracy.

[0015] 3. The adjustment ring of the cutting component can adjust the rotating ring to the position where cutting is required. As market demand changes, the blade position can be adjusted as needed to meet the market demand for straws of different lengths. Multiple sets of blades rotate and cut at the same time, making the cut edges of paper straws smoother. BRIEF DESCRIPTION OF THE DRAWINGS
