Description

Technical Field

[0001] This utility model relates to the field of straw production and processing technology, specifically a cutting structure for straw production. Background Technology

[0002] A straw, also known as a drinking straw, is a cylindrical, hollow plastic product. Its main function is to drink beverages from a cup. It can also be used to suck out the marrow from cooked animal bones. Generally, it is about 0.5cm in diameter. However, when drinking yogurt, bubble tea, or other beverages, thicker straws are used, some with a diameter of 1.2cm. Some less common straws with extremely small diameters are used for drinking hot beverages.

[0003] The above-mentioned technical conditions also have defects: when existing straws are cut during the production and processing, most of them can only support one end of the straw, which reduces the cutting effect of the straw. At the same time, it is not convenient to unload the material, which is not conducive to long-term use.

[0004] Based on this, the present invention designs a cutting structure for straw production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting structure for straw production to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting structure for straw production, comprising two sets of uprights, a top seat, and a straw conveying frame. An electric telescopic rod is fixedly connected to the bottom of the top seat, and a cutting blade is fixedly connected to the bottom end of the electric telescopic rod. A drive motor is fixedly connected to one side of one set of uprights, and a rotating shaft is fixedly connected to the output shaft of the drive motor. A positioning turntable and a cutting turntable are fixedly connected to both sides of the outer wall of the rotating shaft, respectively. Multiple outward-opening placement slots are provided on the cutting turntable. Multiple positioning holes corresponding to the placement slots are provided on the positioning turntable. Positioning posts are provided on the positioning turntable and inside the multiple positioning holes. A concentrator is fixedly connected between the two sets of uprights, and a receiving frame is provided below the concentrator. An air pump is also fixedly connected to one set of uprights. A conveying pipe is connected to the air outlet of the air pump, and a nozzle is connected to one end of the conveying pipe. Receiving holes are provided on the positioning turntable and on the back side of the multiple positioning posts, with the air outlet of the nozzle facing the lowest receiving hole.

[0007] By adopting the above technical solution, both ends of the straw can be supported during cutting, thereby improving the cutting effect of the straw.

[0008] Preferably, a slider is fixedly connected to one end of the positioning post, a guide post is fixedly connected to one side of the slider, a limit frame is fixedly connected to the positioning turntable inside the receiving hole, the guide post is slidably connected to the limit frame, and a spring is provided on one side of the slider outside the guide post, with one end of the spring fixedly connected to the inside of the limit frame.

[0009] By adopting the above technical solution, high-pressure air is sprayed into the receiving hole through the nozzle, and then the slider is pushed towards one side of the positioning post, thereby causing the suction tube sleeved on the positioning post to be pushed out, thus making it convenient to unload the suction tube.

[0010] Preferably, the back side of the positioning turntable is provided with a plurality of infrared receivers corresponding one-to-one with the receiving holes, and an infrared transmitter is fixedly installed on the stand and directly above the nozzle.

[0011] By adopting the above technical solution, the alignment can be monitored using infrared light, resulting in better performance.

[0012] Preferably, one end of the rotating shaft is rotatably connected to another set of uprights.

[0013] By adopting the above technical solution, the rotating shaft becomes more stable during rotation.

[0014] Preferably, the number of placement slots, positioning posts, receiving holes and infrared receivers are all eight sets, and they are arranged in a ring.

[0015] By adopting the above technical solution, the bottom straw can be cut and then unloaded while the top straw is being cut.

[0016] In summary, this application has the following beneficial technical effects: By setting a cutting turntable and a positioning turntable that can rotate synchronously, the straw passes through the placement slot and is fitted onto the positioning post before being cut, thus enabling excellent cutting of the straw. After cutting, the drive motor controls the cut straw to rotate downwards. When it reaches the bottom, the high-pressure gas ejected by the nozzle pushes the slider, causing it to push the straw out of the positioning post, thereby achieving rapid unloading of the straw and increasing its usability. Furthermore, the infrared emitter and infrared receiver ensure accurate straw alignment and improve the cutting effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] A cutting structure for straw production includes two sets of uprights 1, a top seat 2, and a straw conveyor frame 3. The top of the top seat 2 is fixedly connected to the top of the machine frame (the machine frame is an external structure and is not shown in the figure). The straws are pushed by an external drive structure and then guided by the straw conveyor frame 3. An electric telescopic rod 4 is fixedly connected to the bottom of the top seat 2, and a cutting blade 5 is fixedly connected to the bottom end of the electric telescopic rod 4. The cutting blade 5 is moved vertically by the telescopic end of the electric telescopic rod 4, thereby cutting the straws passing below. A drive motor 6 is fixedly connected to one side of the device. The drive motor 6 is a stepper motor with precise rotation control. A rotating shaft 7 is fixedly connected to the output shaft of the drive motor 6. A positioning turntable 8 and a cutting turntable 9 are fixedly connected to both sides of the outer wall of the rotating shaft 7, respectively. The cutting turntable 9 has multiple outwardly opening placement slots 10 for the suction tube to pass through. The positioning turntable 8 has multiple positioning holes 11 corresponding to the placement slots 10. Positioning posts 12 are set on the positioning turntable 8 and inside the multiple positioning holes 11, such as... Figure 3 As shown, one end of the straw passes through the placement groove 10 and is fitted onto the positioning post 12. A collection hopper 13 is fixedly connected between the two sets of uprights 1. A receiving frame 14 is set below the collection hopper 13 to receive the cut straw, thus facilitating subsequent processing. An air pump 15 is also fixedly connected to one set of uprights 1. The air pump 15 can control the nozzle 17 to quickly and intermittently spray pressurized gas, thereby pushing the straw out well. A conveying pipe 16 is connected to the air outlet of the air pump 15. A nozzle 17 is connected to one end of the conveying pipe 16. A receiving hole 18 is opened on the positioning turntable 8 and on the back side of multiple positioning posts 12. The air outlet of the nozzle 17 is directly facing the receiving hole 18 at the bottom. Air can be blown through the nozzle 17 and then blown through the receiving hole 18 onto the straw on the positioning post 12, blowing the straw off the positioning post 12 and causing it to fall into the collection hopper 13, and finally into the receiving frame 14.

[0028] Furthermore, a slider 21 is fixedly connected to one end of the positioning post 12, and a guide post 22 is fixedly connected to one side of the slider 21. A limit frame 23 is fixedly connected to the positioning turntable 8 and inside the receiving hole 18. The guide post 22 is slidably connected to the limit frame 23. A spring 24 is provided on one side of the slider 21 and outside the guide post 22. One end of the spring 24 is fixedly connected to the inside of the limit frame 23. When the nozzle 17 blows air, the gas can impact the slider 21. The thrust generated on the slider 21 when blowing air is greater than the tension of the spring 24, which can push out the suction tube on the positioning post 12.

[0029] Furthermore, multiple infrared receivers 19 corresponding to the receiving holes 18 are provided on the back side of the positioning turntable 8. An infrared transmitter 20 is fixedly installed on the stand 1 and directly above the nozzle 17, which can generate infrared rays to illuminate the infrared receivers 19, thereby achieving precise alignment.

[0030] Furthermore, one end of the rotating shaft 7 is rotatably connected to another set of uprights 1, making the rotating shaft 7 more stable when rotating.

[0031] Furthermore, the number of placement slots 10, positioning posts 12, receiving holes 18 and infrared receivers 19 are all eight sets, and they are arranged in a ring, so that when cutting is performed at the top, the bottom suction tube can be detached.

[0032] The implementation principle of this embodiment is as follows: During use, the straw is conveyed along the straw conveyor frame 3, and then one end of the straw passes through the placement groove 10 and is sleeved on the positioning post 12. At this time, one end of the straw is in contact with one side of the slider 21. Then, the electric telescopic rod 4 is activated, causing the telescopic end of the electric telescopic rod 4 to extend and cut the straw through the cutting blade 5. After one cut is completed, the electric telescopic rod 4 controls the cutting blade 5 to move upward, and the drive motor 6 controls the rotating shaft 7 to rotate, so that the straw to be cut is aligned with the next set of placement grooves 10 and positioning posts 12, and the straw is conveyed again until one end of the straw is in contact with the slider 21. Upon contact, cutting is performed again, and the above operation is repeated. When the first cut straw reaches the bottom, the air pump 15 is activated, and high-pressure gas is sprayed through the delivery pipe 16 and nozzle 17, which enters the receiving hole 18. Then, the slider 21 is pushed to move quickly towards the straw, thereby pushing the straw on the positioning post 12 out and letting it fall into the receiving frame 14 through the lower collection hopper 13. Then, the slider 21 is reset under the action of the spring 24, which facilitates the next cutting. At the same time, the infrared receiver 19 and the infrared emitter 20 can accurately position the placement slot 10 and the straw, increasing the effect of use.
