DETAILED DESCRIPTION
[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] With the continuous development of society, straws have become one of the tools people use in their daily lives to drink. When producing bendable plastic straws, it is necessary to perform a molding operation on the portion of the plastic straw to be bent. Therefore, a molding device for bendable plastic straws is needed. During actual use, most traditional molding devices for bendable plastic straws have fixed threads on the molding wheel of the device and cannot change the length of the threads due to the different lengths of the bending portion of the straw, resulting in reduced applicability of the device. Therefore, the applicant proposes a molding device for bendable plastic straws.
[0024] like Figures 1-6As shown, the utility model provides a technical solution: a forming device for bendable plastic straws, comprising a frame 1, a forming mechanism 2 is fixed to the inner wall of the frame 1, a conveying mechanism 3 is fixed to the inner wall of the forming mechanism 2, the forming mechanism 2 comprises a shell 201, a first motor 202 is fixed to the top of the inner wall of the shell 201, a rotating shaft 203 is fixed to the output end of the first motor 202, a sliding tube 204 is slidably connected to the outer wall of the rotating shaft 203, a sliding groove ring 205 is fixed to the bottom of the sliding tube 204, a positioning frame 206 is slidably connected to the inner wall of the sliding groove of the sliding groove ring 205, a regulating handle 207 is threadedly connected to the top of the positioning frame 206, and the regulating handle 207 is screwed to the top of the regulating handle 207. The threaded end of 07 passes through the top of the positioning frame 206 and is movably connected to the ball 208. A placement sleeve 211 is fixed to the outer wall of the bottom end of the rotating shaft 203. Several rubber rings 212 are fixed to the outer wall of the placement sleeve 211. A forming piece 213 is clamped between adjacent rubber rings 212. One side of the positioning frame 206 is rotatably connected to the lifting plate 209. A cylinder 210 is fixed to the top of the inner wall of the outer shell 201. The output end of the cylinder 210 is fixed to the top of one end of the lifting plate 209. A feed pipe 214 is fixed to the top of the outer wall of the outer shell 201. A discharge pipe 215 is fixed to the bottom of the outer wall of the outer shell 201. A rotating door 216 is rotatably connected to one side of the outer wall of the outer shell 201.
[0025] It should be noted that when the device is in use, first open the rotating door 216, and according to the length of the straw to be bent, push several forming pieces 213 to disengage the forming pieces 213 from the engagement of the rubber ring 212, and push the forming pieces 213 onto the sliding tube 204. Then, control the cylinder 210 to descend to a certain height, and rotate the positioning frame 206, so that one end of the positioning frame 206 corresponds to the slide groove of the slide groove ring 205, and start the cylinder 210 again, so that one end of the positioning frame 206 is inside the slide groove of the slide groove ring 205, and slides and engages with each other in the slide groove, and then rotate the regulating handle 207 so that the ball 208 contacts the outermost forming piece 213. After closing the rotating door 216, The straw is fed into the conveying mechanism 3 through the feed pipe 214, and then under the control of the terminal, the conveying mechanism 3 rotates. At the same time, the first motor 202 also rotates the rotating shaft 203 under the control of the terminal. The rotation of the rotating shaft 203 can drive the sliding tube 204 and several forming pieces 213 on the sliding tube 204 to rotate. Because one end of the positioning frame 206 slides and engages with the inner wall of the slide groove of the slide groove ring 205, and under the action of the ball 208, the positioning frame 206 does not affect the rotation of the forming piece 213. When the straw contacts the forming piece 213, the forming piece 213 will perform a forming operation on the part of the straw to be bent, and the formed straw will be discharged and collected from the discharge pipe 215.
[0026] like Figure 4-Figure 6As shown, the utility model provides a technical solution: a forming device for a bendable plastic straw, comprising a conveying mechanism 3, the conveying mechanism 3 comprising two fixed tubes 301, the opposite ends of the two fixed tubes 301 being fixed to the top and bottom of the inner wall of the shell 201 respectively, a feed hole being provided at the top of the fixed tube 301 at the top, a discharge hole being provided at the top of the fixed tube 301 at the bottom, a fixed block 302 being fixed to the bottom of the fixed tube 301 at the top, a plurality of first springs 303 being fixed to one side of the fixed block 302, a sliding plate 304 being fixed to one end of the plurality of first springs 303, a feed port being provided at the top of one end of the sliding plate 304, the top of the sliding plate 304 being slidably connected to the bottom of the adjacent fixed tube 301, and a first rubber block 3 being fixed to the bottom of one end of the sliding plate 304 05. A second rubber block 314 is fixed to the top of the fixed tube 301 at the bottom, a second motor 306 is fixed to the top of the inner wall of the shell 201, and the second motor 306 is located inside the fixed tube 301 at the top. A rotating roller 307 is fixed to the output end of the second motor 306, and several groups of fixing rods 308 are fixed to the outer wall of the rotating roller 307. The top and bottom of each group of fixing rods 308 are respectively slidably connected with a clamping plate 309, and a clamping block 310 is clamped in the clamping groove of the clamping plate 309. A heating rod 311 is fixed between each group of clamping blocks 310, and a fixing frame 312 is fixed to the side of one end of the clamping plate 309. Several second springs 313 are fixed to the top of one side of each group of fixing rods 308, and one end of several second springs 313 is fixed to the side of one end of the adjacent fixing frame 312.
[0027] It should be noted that when the device is in use, the straw will first fall into the feeding hole of the top fixed tube 301 through the forming mechanism 2. When the second motor 306 rotates, the rotation of the rotating roller 307 will drive the clamping plate 309 to rotate. When the clamping plate 309 on the top of one group of fixed rods 308 contacts the first rubber block 305, the first rubber block 305 will press the clamping plate 309, and the clamping plate 309 will move under the action of the second spring 313. The top of one group of fixed rods 308 will be opened. Under the continuous rotation of the rotating roller 307, when the stretching of the second spring 313 reaches a certain limit, the sliding plate 304 will move under the action of the first spring 303, so that the feeding port on the sliding plate 304 corresponds to the feeding hole on the fixed tube 301, so that the straw inside the feeding hole of the fixed tube 301 falls into one group of fixed rods 308, and the heating rod 311 in one group of fixed rods 308 is inserted. Inside the straw, the heat released by the heating rod 311 can cause the straw to soften to a certain extent. As the rotating roller 307 continues to rotate, the first rubber block 305 will break away from the contact with the clamping plate 309 due to its own flexibility. The clamping plate 309 will be reset under the action of the second spring 313, and the clamping groove at the bottom of the clamping plate 309 will be clamped with the clamping block 310 at the top of the heating rod 311. When the straw is formed by the forming mechanism 2, as the rotating roller 307 continues to rotate, the clamping plate 309 at the bottom of one group of fixed rods 308 will contact the second rubber block 314 on the bottom fixed tube 301. Under the action of the second rubber block 314, the bottom clamping plate 309 will move, causing the bottom of one group of fixed rods 308 to open, and the straw will be discharged from the discharge hole of the bottom fixed tube 301 into the discharge pipe 215 of the forming mechanism 2, and collected from the discharge device of the discharge pipe 215.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
