A pipe cutting device for producing a three-hole straw

Abstract

This utility model provides a cutting device for producing three-hole straws, relating to the field of straw production. It includes a support plate with five placement slots on its top. A movable frame is slidably connected to the top of the support plate, and a cylinder is fixedly connected to the inner cavity of the movable frame. A fixed plate is fixedly connected to the output end of the cylinder. This utility model uses placement slots to hold straws to be cut. Because there are five placement slots, five long straws can be cut simultaneously, improving the cutting efficiency. Simultaneously, placing the straws inside the placement slots prevents them from shifting due to force during the cutting process, ensuring the flatness of the cut and improving the aesthetics of the finished product. A moving mechanism is provided to adjust the position of the movable frame, thereby adjusting the position of the cutting blade to cut long straws into short straws of different lengths.

Description

Technical Field

[0001] This utility model belongs to the field of straw production, specifically a straw cutting device for producing three-hole straws. Background Technology

[0002] A straw is a small tubular tool used for drinking liquids. It mainly consists of a tube and a mouthpiece. It is used to draw liquids from a cup or container into the mouth. A three-hole straw usually refers to a straw with three small holes. This design helps to control the flow of fluid and the amount of air inhaled. It is also sometimes used for liquid management in the mouth or nose.

[0003] Three-hole straws require a cutting process during production to divide a long straw into multiple shorter straws. During the cutting process, the cutting device applies pressure to the straw itself, which can easily cause the straw to shift in position, resulting in irregular cuts. This not only affects the appearance but also the straw's usability and sales.

[0004] In summary, this utility model provides a cutting device for producing three-hole straws to solve the above problems. Utility Model Content

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0021] Example 1

[0022] like Figure 1-4 The image shows the first embodiment of this utility model, which provides a cutting device for producing three-hole straws. It includes a support plate 1, with five placement slots 2 on the top of the support plate 1. A movable frame 3 is slidably connected to the top of the support plate 1. A cylinder 4 is fixedly connected to the inner cavity of the movable frame 3. A fixing plate 5 is fixedly connected to the output end of the cylinder 4. A slitting blade 6 is fixedly connected to the bottom of the fixing plate 5. A receiving groove 7 is formed in the inner cavity of the placement slots 2. The bottom of the slitting blade 6 extends into the inner cavity of the receiving groove 7 and is movably connected to it. The inner cavity is provided with a moving mechanism 8, which includes a threaded rod 801. The threaded rod 801 is located in the inner cavity of the support plate 1 and is movably connected to the inner cavity of the support plate 1 through a bearing. The surface of the threaded rod 801 is threadedly connected with a threaded sleeve 802. Both sides of the support plate 1 are provided with through grooves 803. Both sides of the threaded sleeve 802 are fixedly connected with connecting plates 804. The side of the connecting plate 804 away from the threaded sleeve 802 is fixedly connected to the inner wall of the movable frame 3. The connecting plate 804 is slidably connected to the inner cavity of the through groove 803. Support legs 9 are fixedly connected to the bottom of the support plate 1 around its perimeter.

[0023] like Figure 1-4As shown, the support plate 1 is used to support and fix the surface components, and the placement slot 2 is used to place the straws to be cut. Since there are five placement slots 2, five long straws can be cut simultaneously, improving the cutting efficiency of the straws. At the same time, placing the straws inside the placement slot 2 can prevent the straws from shifting due to force during the cutting process, ensuring the flatness of the cut and thus improving the appearance of the finished product. The movable frame 3 is used to support the cylinder 4. When the output end of the cylinder 4 extends or retracts, it can work with the fixed plate 5 to adjust the height of the cutting blade 6, so that the cutting blade 6 can descend and cut the straws. The receiving slot 7 is used to provide space for the cutting blade 6 to move. The moving mechanism 8 is used to adjust the position of the movable frame 3 in order to adjust the position of the cutting blade 6 so as to cut the long straws into short straws of different lengths.

[0024] Example 2

[0025] Reference Figure 1 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] In this embodiment, the rear end of the threaded rod 801 extends through to the back of the support plate 1 and is fixedly connected to the driven wheel 805.

[0027] A servo motor 806 is installed at the bottom of the support plate 1. The output shaft of the servo motor 806 is connected to the drive wheel 807. The driven wheel 805 and the drive wheel 807 are connected by belt drive.

[0028] like Figure 1 and 3 As shown, the servo motor 806 can drive the drive wheel 807 to rotate when it is running. Since the driven wheel 805 and the drive wheel 807 are connected by belt drive, when the drive wheel 807 rotates, it can cooperate with the driven wheel 805 to drive the threaded rod 801 to rotate. When the threaded rod 801 rotates, it can adjust the position of the threaded sleeve 802, and then cooperate with the connecting plate 804 to drive the movable frame 3 to move, thereby adjusting the cutting position of the slitting blade 6.

[0029] Example 3

[0030] Reference Figure 1-3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0031] In this embodiment, a receiving box 10 is provided on the front side of the support plate 1, and a mounting frame 11 is fixedly connected to the side of the two front support legs 9 that are close to each other. Mounting blocks 12 are fixedly connected to both sides of the back of the receiving box 10. The rear end of the mounting block 12 extends into the inner cavity of the mounting frame 11 and is detachably connected to the inner cavity of the mounting frame 11.

[0032] The surface of the servo motor 806 is fixedly connected to a fixing sleeve 13, and the top of the fixing sleeve 13 is fixedly connected to the bottom of the support plate 1.

[0033] Limiting plates 14 are fixedly connected to both sides of the inner cavity of the movable frame 3, and the bottom of the limiting plates 14 is slidably connected to the surface of the support plate 1.

[0034] like Figure 1-3 As shown, the mounting bracket 11 and the mounting block 12 cooperate to install the receiving box 10. The receiving box 10 is used to store the cut straws. The fixing sleeve 13 is used to fix the servo motor 806 to improve the stability of the servo motor 806 during use. The limiting piece 14 is used to limit the movement of the movable frame 3.

[0035] In use, first place the straw into the placement slot 2, then start the servo motor 806. When the servo motor 806 is running, it can drive the drive wheel 807 to rotate. Since the driven wheel 805 and the drive wheel 807 are connected by belt drive, when the drive wheel 807 rotates, it can work with the driven wheel 805 to drive the threaded rod 801 to rotate. When the threaded rod 801 rotates, it can adjust the position of the threaded sleeve 802, and then work with the connecting plate 804 to drive the movable frame 3 to move, adjusting the cutting position of the slitting knife 6. After adjusting to the appropriate position, turn off the servo motor 806 and start the cylinder 4. When the output end of the cylinder 4 extends, it can work with the fixing plate 5 to adjust the height of the slitting knife 6, so that the slitting knife 6 can descend and cut the straw. After one cut, push the long straw forward so that the cut straw is pushed into the receiving box 10, and then the second cut can be performed.
