Description

Technical Field

[0001] This utility model belongs to the field of straw processing technology, and in particular relates to a splash-proof device for processing straws. Background Technology

[0002] A straw is a common tool for drawing liquids. It is hollow inside with smooth top and bottom openings and a relatively straight body. The top is for the lips to hold in the mouth. By sucking with the tongue, a negative pressure is created in the straw, drawing the liquid below the straw into the mouth. To reduce costs and make it easier to use, straws are generally made of plastic.

[0003] Generally, hot melt plastic liquid is extruded into a molding machine, pushed by a screw conveyor mechanism and squeezed out of the mold slot, falling into cold water to cool and solidify, and then cut at equal intervals by an electric cutter. In order to avoid plastic debris splashing, most factories use anti-splash devices to protect the cut area, but they ignore that the debris can easily stick to the surface of the straw or processing machinery, which is also inconvenient for later cleaning. Therefore, this application proposes an anti-splash device for processing straws. Utility Model Content

[0004] This application proposes a splash-proof device for processing straws. By setting up a series of structures, it solves the problem that in the general process, hot melt plastic liquid is squeezed into a molding machine, pushed by a screw conveyor mechanism to be squeezed out from the mold slot, falls into cold water to cool and solidify, and then is cut at equal intervals by an electric cutter. In order to avoid plastic debris splashing, most factories choose splash-proof devices to protect the cut area, but they ignore the problem that the debris can easily stick to the surface of the straw or processing machinery, which is also inconvenient for later cleaning.

[0005] This application proposes a splash-proof device for processing straws, including a base plate, a housing fixed to the left side of the top of the base plate, and slots fixed at the center of both sides of the housing. A straw strip is inserted horizontally between the left and right slots. A cover plate is fixed to the top of the housing, and a frame is fixed to the right side of the bottom of the cover plate. An electric cutter is movably connected between the left and right sides inside the frame. A motor is fixed to the left side of the outside of the frame. A collection box is fixed to the left side of the bottom of the cover plate. A filter screen is fixed to the left side of the inside of the cover plate. An air pump is fixed to the left side of the top of the cover plate. A support plate is fixed to the upper left of the inside of the housing. A bent pipe is fixed to the upper right corner of the outside of the collection box, and a collar is fixed to the bottom of the bent pipe. An air suction hole is fixed around the right side surface of the collar.

[0006] Furthermore, the straw strip is horizontally embedded in the collar, and the suction hole is connected to the curved tube.

[0007] Furthermore, the air pump is connected to the collection box through the filter screen, and the lower left corner of the collection box rests on the support plate.

[0008] Furthermore, a slot is provided at the lower right corner of the outer shell, a conveyor is horizontally fixed at the right side of the top of the base plate, a knife holder is fixed at the center of the right side inside the shell, a roller is movably connected between the front and rear of the center of the right side inside the shell, and a motor is fixed at the center of the right side of the rear of the outer shell.

[0009] Furthermore, the output end of motor four is fixedly connected to a roller, which is located above the tool holder.

[0010] Furthermore, a sleeve block is fixed between the shell and the left slot, and a second motor is fixed at the rear of the sleeve block. Gear discs are movably connected to the upper and lower parts inside the sleeve block, and a connecting arm is fixed at the center of the front end of the gear disc. A bracket is fixed to the left side of the connecting arm, and a pressure roller is movably connected between the front and rear of the bracket. A third motor is fixed at the rear of the bracket. The left side of the straw strip is embedded in the sleeve block.

[0011] Furthermore, the output end of motor three is fixedly connected to the pressure roller, which is symmetrically attached to the upper and lower parts of the left side of the straw strip.

[0012] Furthermore, the output end of motor two is fixedly connected to the top gear plate, and the two sets of gear plates inside the sleeve rotate in opposite directions.

[0013] As can be seen from the above technical solution, during use, the straw passes through the slots on both sides of the shell and is horizontally embedded inside. It moves from left to right through the transmission mechanism on the left side to be cut. The generated debris will remain in the shell under the shielding of the shell. After the air pump is started, negative pressure is generated at the air suction hole on the right side of the collar through the filter screen, which guides the splashed residue through the air suction hole and the curved tube into the collection box for storage. This solves the problem of squeezing hot melt plastic liquid into the molding machine, pushing it out of the mold slot under the push of the screw conveyor mechanism, dropping it into cold water to cool and solidify, and then cutting it at equal intervals by the electric cutter. In order to avoid plastic debris splashing, most factories choose anti-splash devices to protect the cutting area, but they ignore the problem that debris is easy to stick to the surface of the straw or processing machinery, which is also inconvenient for later cleaning.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the anti-splash device for processing straws not only realizes the synchronous collection of cutting residue and the convenient export of finished straws, but also realizes the smooth pushing of the straw plastic strip;

[0015] (1) A collection box is fixed on the left side of the bottom of the cover plate. The suction strip passes through the slots on both sides of the shell and is horizontally embedded inside. It moves from left to right through the transmission mechanism on the left side to be cut. The generated debris will remain in the shell under the cover of the shell. After the air pump is started, negative pressure is generated at the suction hole on the right side of the collar through the filter screen. The splashed residue is introduced into the collection box through the suction hole and the bent pipe. The garbage can be removed by removing the cover plate and opening the back plate of the collection box.

[0016] (2) By fixing a knife holder at the center of the right side inside the shell, when the straw strip moves horizontally to the right side inside the shell, motor one will start immediately and rotate the electric knife back and forth in the frame. The knife holder will cut each straw strip evenly at a certain distance above the knife holder. The finished product will be pushed out from the slot on the right side by the roller controlled by motor four. Because the left side of the conveyor is embedded in the slot, the finished straw can be received and transported synchronously.

[0017] (3) A pressure roller is connected between the front and rear of the bracket. When the straw strip enters the housing, the motor rotates the upper gear plate inside the sleeve block. The top gear plate meshes with the bottom gear plate, guiding the connecting arm installed at the center of the gear plate to rotate in opposite directions, so that the pressure roller clamps and fixes the straw strip. Then, the motor rotates the pressure roller to push the horizontally moving straw strip. The clamping distance can be adjusted. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] See Figures 1-4 .

[0027] Generally, hot melt plastic liquid is extruded into a molding machine, pushed by a screw conveyor mechanism, and extruded from the mold slot, falling into cold water to cool and solidify. Then, it is cut at equal intervals by an electric cutter. To avoid plastic debris splattering, most factories use splash guards to protect the cut area, but they overlook the fact that debris easily adheres to the surface of the straw or processing machinery, making subsequent cleaning difficult. Therefore, this application proposes a splash guard for processing straws, including a base plate 1. A housing 2 is fixed to the left side of the top of the base plate 1, and slots 6 are fixed to the center of both sides of the housing 2. A straw strip 5 is horizontally inserted between the left and right slots 6. A cover plate 7 is fixed to the top of the housing 2, and a frame 8 is fixed to the right side of the bottom of the cover plate 7. An electric cutter 27 is movably connected between the left and right sides inside the body 8. A motor 9 is fixed to the left side of the outside of the frame 8. A collection box 12 is fixed to the left side of the bottom of the cover plate 7. A filter screen 11 is fixed to the left side inside the cover plate 7. An air pump 10 is fixed to the left side of the top of the cover plate 7. A support plate 21 is fixed to the upper left side inside the shell 2. A bent pipe 20 is fixed to the upper right corner of the outside of the collection box 12, and a collar 22 is fixed to the bottom of the bent pipe 20. An air suction hole 23 is fixed around the right side surface of the collar 22. A suction tube 5 is horizontally embedded in the collar 22. The air suction hole 23 is connected to the bent pipe 20. The air pump 10 passes through the filter screen 11 and is connected to the collection box 12. The lower left corner of the collection box 12 overlaps the support plate 21. Specifically, as shown... Figure 1 and Figure 2 As shown, the straw strip 5 passes through the slots 6 on both sides of the housing 2 and is horizontally embedded inside them. It moves from left to right through the transmission mechanism on the left side to be cut. The generated debris will remain in the housing 2 under the cover of the housing 2. After the air pump 10 is started, a negative pressure is generated at the air suction hole 23 on the right side of the collar 22 through the filter screen 11, and the splashed residue is guided into the collection box 12 for storage through the air suction hole 23 and the bent tube 20.

[0028] Furthermore, a slot 4 is provided at the lower right corner of the outer side of the housing 2; a conveyor 3 is horizontally fixed at the right side of the top of the base plate 1; a tool holder 26 is fixed at the center of the right side inside the housing 2; a roller 25 is movably connected between the front and rear sides at the center of the right side inside the housing 2; a motor 24 is fixed at the center of the right side of the rear of the outer side of the housing 2; the output end of the motor 24 is fixedly connected to the roller 25 in front; the roller 25 is located above the tool holder 26. Specifically, as shown... Figure 1 and Figure 3As shown, when the straw strip 5 moves horizontally to the right side inside the housing 2, the motor 9 is turned on. The electric cutter 27 rotates back and forth in the frame 8 and cuts each straw strip 5 evenly at a certain distance above the cutter holder 26. The finished product will be pushed out from the slot 6 on the right side by the roller 25 controlled by the motor 24 and will continue to be transported to the right by the conveyor 3.

[0029] Furthermore, a sleeve block 13 is fixed between the housing 2 and the left slot 6, and a second motor 18 is fixed to the rear of the sleeve block 13. Gear discs 17 are movably connected to the upper and lower parts of the sleeve block 13, and a connecting arm 16 is fixed to the center of the front end of the gear disc 17. A bracket 15 is fixed to the left side of the connecting arm 16, and a pressure roller 14 is movably connected between the front and rear of the bracket 15. A third motor 19 is fixed to the rear of the bracket 15. The left side of the straw strip 5 is embedded in the sleeve block 13. The front of the output end of the third motor 19 is fixedly connected to the pressure roller 14. The pressure roller 14 is symmetrically attached to the upper and lower parts of the left side of the straw strip 5. The front of the output end of the second motor 18 is fixedly connected to the top gear disc 17. The two sets of gear discs 17 inside the sleeve block 13 rotate in opposite directions. Specifically, as shown... Figure 1 and Figure 4 As shown, when the straw strip 5 just enters the housing 2, the motor 2 18 first rotates the gear plate 17 inside the sleeve block 13, so that the top gear plate 17 meshes with and pushes the bottom gear plate 17, guiding the connecting arm 16 installed at the center of the gear plate 17 to rotate in opposite directions, so that the pressure roller 14 engages and fixes the straw strip 5. The motor 3 19 rotates the pressure roller 14 to push the horizontally moving straw strip 5.

[0030] As can be seen from the above technical solution, when the straw strip 5 enters the housing 2, the toothed disc 17 on the upper part of the sleeve block 13 is rotated by the second motor 18, so that the top toothed disc 17 meshes and pushes the bottom toothed disc 17. The connecting arm 16 installed at the center of the toothed disc 17 rotates in opposite directions, so that the pressure roller 14 engages and fixes the straw strip 5. Then, the pressure roller 14 is rotated by the third motor 19 to push the horizontally moving straw strip 5. When the straw strip 5 moves horizontally to the right side of the housing 2, the first motor 9 is turned on. The electric cutter 27 rotates back and forth in the frame 8. The blade holder 26 cuts each straw strip 5 evenly at a certain distance. The finished product will be pushed out from the slot 6 on the right side by the roller 25 controlled by the fourth motor 24. Since the left side of the conveyor 3 is embedded in the slot 4, the finished straw can be received and transported simultaneously.

[0031] The debris generated during this process will remain inside the housing 2 under the cover of the housing 2. After the air pump 10 is started, negative pressure is generated at the air suction hole 23 on the right side of the collar 22 through the filter screen 11, and the splashed residue is guided into the collection box 12 through the air suction hole 23 and the bent pipe 20. The garbage can be removed by removing the cover plate 7 and opening the back plate of the collection box 12. This solves the problem of squeezing hot melt plastic liquid into the molding machine, pushing it out of the mold slot 6 under the push of the screw conveyor mechanism, dropping it into cold water to cool and set, and then cutting it at equal intervals by the electric cutter 27. In order to avoid plastic debris splashing, most factories use anti-splash devices to protect the cutting area, but they ignore the problem that debris is easy to stick to the surface of the suction pipe or processing machinery, which is also inconvenient for later cleaning.

The embodiments of this application described above do not constitute a limitation on the scope of protection of this application.
