Description
Technical Field
[0001] This utility model belongs to the field of automatic straw forming, specifically relating to an automatic forming device for bendable plastic straws. Background Technology
[0002] Straws are widely used in daily life. Nowadays, straw production is mostly done by machines. The specific production process is as follows: raw materials, such as polypropylene and polylactic acid, are first added to an extruder. Under high temperature and pressure, the granular raw materials gradually turn into a viscous fluid, which is then released from the nozzle of the extruder in strips and accumulates in a container. Once the ejected tubular material reaches the required state, a thin rod can be used to pull the ejected tubular viscous material, which then becomes a long tubular substance. After cooling with water, the straw is initially formed. However, after the straw forming machine produces the straw, manual cutting by workers is inefficient and requires high cutting strength. How to cut straws quickly and produce straws of different lengths has become a pressing technical problem that needs to be solved.
[0003] This invention attempts to mitigate or at least alleviate such problems or defects by providing a new or otherwise improved automatic straw forming method. Utility Model Content

[0026] This utility model discloses an automatic forming device for bendable plastic straws. Through a set of follow-up clamping components, after the plastic straw is formed from the plastic straw forming machine, it first passes through the follow-up clamping components and then the straw cutting component. Then, by activating the first electric cylinder, the clamping cylinder moves to the right, thereby clamping and positioning the plastic straw. When cutting straws of different lengths, only the displacement distance of the clamping cylinder needs to be adjusted by adjusting the first electric cylinder, thus adapting to cutting straws of varying lengths. By using the installed tube-cutting components, once the suction tube is inserted into the gap between the lower and upper positioning plates, the lower and upper push cylinders can be activated to push the upper and lower positioning plates closer together to further position the suction tube. Activating the second electric cylinder can quickly push the displacement plate and cutter downwards, cutting the suction tube placed between the follow-up clamping components and the tube-cutting components. This effectively prevents the suction tube from shaking during cutting and allows for rapid batch tube-cutting operations, improving cutting efficiency. Attached Figure Description

[0037] In the embodiments, by Figure 1-6 An automatic forming device for bendable plastic straws is provided, wherein... Figure 1 This is a schematic diagram of the overall structure of the automatic forming device for bendable plastic straws of this utility model; Figure 2 This is a structural schematic diagram of the automatic forming device for bendable plastic straws from another angle. Figure 3 This is a front view of the automatic forming device for bendable plastic straws according to this utility model; Figure 4 This is a schematic diagram of the overall structure of the follower clamping component of this utility model; Figure 5 This is a schematic diagram of the overall structure of the pipe-cutting component of this utility model; Figure 6 This utility model Figure 5The enlarged view at point A includes a workbench 1 with a mounting surface; a plastic straw forming machine 2 detachably mounted on the mounting surface; a follower clamping component 3, including a machine base 31 detachably mounted on the mounting surface, with a first slide rail 32 detachably mounted on the machine base 31; and a baffle 33 detachably mounted on the machine base 31, with a first electric cylinder 34 detachably mounted on the baffle 33, the output end of which can exit from the baffle. The following components pass through: a slide plate 35, which is detachably connected to the output end of the first electric cylinder 34, and has a slider 36 at the bottom of the slide plate 35 that can slide on the first slide rail 32; a clamping cylinder 37, which is detachably mounted on the slide plate 35, and has a clamping piece 38 removably arranged on the clamping end of the clamping cylinder 37; and a cutting member 4 for positioning and cutting plastic straws, which is detachably arranged on the mounting plane and located on one side of the follower clamping member 3.
[0038] The overall concept of this utility model is as follows: After the plastic straw is formed from the plastic straw forming machine 2, it passes sequentially through the follower clamping component 3 and the straw cutting component 4. Then, by activating the first electric cylinder 34, the clamping cylinder 37 moves to the right. Activating the clamping cylinder 37 then clamps and positions the plastic straw. When cutting straws of different lengths, only the displacement distance of the clamping cylinder 37 needs to be adjusted by adjusting the first electric cylinder 34, thus adapting to different straw cutting operations. The tube-cutting component 4, when the straw is inserted into the gap between the lower positioning plate 43 and the upper positioning plate 45, can push the upper positioning plate 45 and the lower positioning plate 43 closer together by opening the lower push cylinder 42 and the upper push cylinder 44 to further position the straw. By opening the second electric cylinder 47, the displacement plate 48 and the cutter 491 can be quickly pushed down to cut the straw placed between the follower clamping component 3 and the tube-cutting component 4. This can effectively prevent the straw from shaking during the cutting process and can also quickly perform batch cutting operations, thus improving the efficiency of the cutting process.
[0039] It should also be noted that the plastic straw forming machine 2 is a known component in the prior art, and its working principle is a known technology, so it will not be described in detail in this application.
[0040] In some embodiments, in order to further prevent the slider 36 from falling off the first slide rail 32, a stop plate 39 is detachably installed at one end of the machine base 31, and the stop plate 39 is located at the end of the first slide rail 32.
[0041] In some embodiments, more specifically, in order to further enhance the stability of the connection between the clamping plate 38 and the straw to be cut, a rubber sheet is detachably installed on the clamping plate 38, and the size of the rubber sheet is adapted to the size of the clamping plate 38.
[0042] Next, a more specific structure and construction of the pipe cutting component 4 will be given for further explanation. The pipe cutting component 4 includes a pipe cutting frame 41, which is detachably mounted on the mounting plane and located on one side of the follower clamping component 3; a lower push cylinder 42, which is detachably mounted on the pipe cutting frame 41, and a lower positioning plate 43 is detachably mounted on the output end of the lower push cylinder 42; and an upper push cylinder 44, which is detachably mounted on the pipe cutting frame 41 and has a lower positioning plate 43 detachably mounted on the output end of the upper push cylinder 42. An upper positioning plate 45 is detachably mounted on the output end of the push cylinder 44; a second slide rail 46 is detachably mounted on one side of the pipe cutting frame 41; a second electric cylinder 47 is detachably mounted on one side of the pipe cutting frame 41; a displacement plate 48 has a second slider 49 at its bottom that can slide on the second slide rail 46, and the displacement plate 48 is detachably connected to the output end of the second electric cylinder 47; and a cutter 491 is detachably mounted on one end of the displacement plate 48.
[0043] Next, the overall operating principle of the tube cutting component 4 will be further explained. After the straw is inserted into the gap between the lower positioning plate 43 and the upper positioning plate 45, the upper positioning plate 45 and the lower positioning plate 43 can be pushed closer to each other by opening the lower push cylinder 42 and the upper push cylinder 44 to further position the straw. By opening the second electric cylinder 47, the displacement plate 48 and the cutter 491 can be quickly pushed down to cut the straw placed between the follower clamping component 3 and the tube cutting component 4. This can effectively prevent the straw from shaking during the cutting process and can also quickly perform batch cutting operations, thus improving the efficiency of the cutting process.
[0044] In some embodiments, more specifically, in order to further improve the stability of the lower positioning plate 43 and the upper positioning plate 45 when positioning the suction tube, a lower insert can be detachably installed on the lower positioning plate 43, and the diameter of the lower insert is adapted to the diameter of the lower positioning plate 43. An upper insert can also be detachably installed on the upper positioning plate 45, and the diameter of the upper insert is adapted to the diameter of the upper positioning plate 45.
[0045] In some embodiments, more specifically, in order to further stabilize the position of the second electric cylinder 47 on the pipe cutting frame 41, a sleeve 492 is detachably installed on the pipe cutting frame 41, and the sleeve 492 can cover the second electric cylinder 47 within it.
[0046] In summary, through the deployed follow-up clamping component 3, after the plastic straw is formed from the plastic straw forming machine 2, the plastic straw first passes through the follow-up clamping component 3 and the straw cutting component 4 in sequence. Then, by activating the first electric cylinder 34, the clamping cylinder 37 is driven to move to the right. Subsequently, by activating the clamping cylinder 37, the plastic straw can be clamped and positioned. When cutting straws of different lengths, only the displacement distance of the clamping cylinder 37 needs to be adjusted by adjusting the first electric cylinder 34, which can adapt to the cutting of different lengths. The deployed straw cutting component 4... After the straw is inserted into the gap between the lower positioning plate 43 and the upper positioning plate 45, the upper positioning plate 45 and the lower positioning plate 43 can be pushed closer to each other by opening the lower push cylinder 42 and the upper push cylinder 44 to further position the straw. The displacement plate 48 and the cutter 491 can be quickly pushed down by opening the second electric cylinder 47, which can cut the straw placed between the follower clamping member 3 and the cutting member 4. This can effectively prevent the straw from shaking during the cutting process and can quickly perform batch cutting operations, thus improving the efficiency of the cutting process.
