Description

Technical Field

[0001] This utility model belongs to the field of straw preparation technology, specifically relating to a straw dispensing device. Background Technology

[0002] As people pay more attention to food hygiene, disposable straws, as a type of catering product, have also attracted attention. People usually use disposable straws when drinking soy milk, milk, beverages, milk tea, etc. The production process requires corrugating the straws. During corrugating, an automatic feeding device is used to transport the straws to the corrugating device. The straws usually fall onto the pushing mechanism first, and then the pushing mechanism pushes the straws onto the corrugating device. Because straws are very light, multiple straws may be pushed into the corrugating device at one time, which may cause the straw corrugating to fail, increase the error rate of straw corrugating, and cause unnecessary cost waste. Further improvements are needed. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below through specific embodiments.

[0024] Reference Figures 1 to 6 As shown, a straw dispensing device includes a dispensing frame 1, a feeding bin 2 mounted on the dispensing frame 1, a dispensing roller 3 rotatably mounted on the feeding bin 2 to separate straws one by one, a limiting plate 4 extending downward along the circumference of the dispensing roller 3 in the feeding bin 2, a guiding mechanism 5 positioned between the dispensing frame 1 and the feeding bin 2 to guide the straws away from the dispensing roller 3, and a rotating mechanism mounted on the dispensing frame 1 and connected to and driving the dispensing roller 3 to rotate. Specifically, the rotating mechanism drives the dispensing roller 3 to rotate clockwise downward to separate and send out the straws entering the feeding bin 2 one by one. The dispensing roller 3 is rotatably mounted in the feeding bin 2 via a rotating shaft 6. The rotating mechanism can use a motor and a transmission assembly to drive the dispensing roller to rotate. This method is a common driving method in the mechanical field, and its specific composition and working principle will not be further elaborated here.

[0025] The feeding hopper 2 includes a first vertical plate 21 and a second vertical plate 22 disposed opposite to each other on the material distribution rack 1, a first connecting plate 23 and a second connecting plate 24 connecting the first vertical plate 21 and the second vertical plate 22, a partition plate 25 movably disposed between the first vertical plate 21 and the second vertical plate 22, a fixing component 26 disposed between the partition plate 25 and the first plate 21, and a guide component 27 disposed between the partition plate 25 and the first vertical plate 21. A feeding chamber 28 for the suction tube to enter is formed between the partition plate 25 and the second vertical plate 22. The first connecting plate 23 and the second connecting plate 24 are disposed opposite to each other on both sides of the first vertical plate 21. Specifically, the first connecting plate 23 includes a vertical section 231 connecting the first vertical plate 21 and the second vertical plate 22, an extension section 232 extending downward at an incline connected to the lower end of the vertical section 231, and a guide section 233 extending downward at an incline connected to the lower end of the extension section 232. The second connecting plate 24... The system includes a support section 241 located on one side of the distributing roller 3 and supported at the lower end of the partition plate 25, and a guide section 242 extending downward at an angle near the end of the support section 241 close to the distributing roller 3. By defining the structure of the first connecting plate 23 and the second connecting plate 24, the partition plate 25 can move stably between the first upright plate 21 and the second upright plate 22. One end of the partition plate 25 is supported on the extension section 232 and the guide section 233, and the other end is supported on the support section 241. The surface opposite to the distributing roller 3 is adapted to the upper surface of the distributing roller 3. When distributing materials with a suction tube, the position of the partition plate 25 can be adjusted according to the different lengths of the suction tubes to adapt to the distributing process of suction tubes of different lengths. Furthermore, the feeding bin 2 is provided with a mounting block 29 for mounting the limiting plate 4. The two ends of the mounting block 29 are connected to the first upright plate 21 and the second upright plate 22, respectively. The lower end of the limiting plate 4 forms a first connecting part 41 connected to the mounting block 29.

[0026] The fixing assembly 26 includes two fixing rods 261 that are spaced apart on the partition plate 25 and extend to the first upright plate 21, two fixing sleeves 262 that are spaced apart on the first upright plate 21 and can pass through the fixing rods 261, and two fixing blocks 263 that are threadedly engaged with the ends of the two fixing rods 262 and can abut against the side of the first upright plate 21. The partition plate 25 is fixed after being moved by the cooperation of the fixing rods 261 and the fixing blocks 263.

[0027] The guide assembly 27 includes two guide rods 271 spaced apart on the first upright plate 21 and two guide grooves 272 spaced apart on the partition plate 25 for the guide rods 271 to pass through. The guide grooves 272 extend downward from the top of the partition plate 25. One end of the guide rod 271 is connected to the first upright plate 21 and the other end is connected to the second upright plate 22. The guide rods 271 and the guide grooves 272 cooperate to guide the movement of the partition plate 25 and ensure the use of the adjusted feeding chamber 28.

[0028] The dispensing roller 3 includes a dispensing roller body 31, a plurality of suction tube positioning grooves 32 circumferentially distributed on the dispensing roller body 31, and two annular limiting grooves 33 spaced apart around the dispensing roller body 31. The annular limiting grooves 33 are connected to the plurality of suction tube positioning grooves 32. The limiting plate 4 is opposite to the outer circumferential surface of the dispensing roller 3 and restricts the suction tubes that rotate downward with the dispensing roller 3 from disengaging from the suction tube positioning grooves 32. Specifically, the diameter of the suction tube is adapted to the diameter of the suction tube positioning groove 32, so that only one suction tube can be inserted into each suction tube positioning groove 32.

[0029] The material guiding mechanism 5 includes a discharge chamber 51 opposite to the lowest-positioned suction tube positioning groove 32. The suction tube exits the suction tube positioning groove 32 through the discharge chamber 51. Specifically, the material guiding mechanism 5 also includes two material guiding components located on both sides of the distributing roller 3. The material guiding components include a first guide plate 52 disposed on the distributing frame 1 opposite to the lowest-positioned suction tube positioning groove 32, a second guide plate 53 disposed in the feeding bin 2 extending downward along the circumference of the distributing roller 3 and opposite to the outer circumferential surface of the distributing roller 3, a first inclined guide surface 54 disposed on the opposing surfaces of the first guide plate 52 and the second guide plate 53, and a second inclined guide surface 55 disposed on the second guide plate 53 opposite to the first inclined guide surface 54. The discharge chamber 51 is formed between the first inclined guide surface 54 and the second inclined guide surface 55. The distributing roller 3 rotates so that the upper suction tube positioning groove 32 is directed towards the discharge chamber 51. The tube is rotated downwards to face the discharge chamber 51, so that the tube in the tube positioning groove 32 is separated from the distributing roller 3 through the discharge chamber 51. Furthermore, the two guiding components are opposite to the two annular limiting grooves 33. One end of the first guiding plate 52 can be embedded in the opposite annular limiting groove 33, and the second guiding plate 53 is opposite to the opposite annular limiting groove 33. Furthermore, the upper end of the second guiding plate 53 has a second connecting part 531 connected to the mounting block 29, and the limiting plate 4 is located between the two second guiding plates 53, opposite to the tube positioning groove 32. By limiting the relative position of the limiting plate 4 and the two second guiding plates 53, the tube will always be placed in the tube positioning groove 32 under the action of the limiting plate 4 and the second guiding plate 53 during the process from being embedded in the tube positioning groove 32 to being separated from the distributing roller 3 through the discharge chamber 51, and will not be laterally separated from the tube positioning groove 32.

[0030] During straw feeding, multiple stacked straws enter the feeding chamber 28. As the rotating mechanism drives the feeding roller 3 to rotate downwards, the straws will be stuck in the corresponding straw positioning grooves 32. As the feeding roller 3 rotates downwards to its lowest point, the straw positioning groove 32 is opposite to the discharge chamber 51 in the guiding mechanism 5. The feeding roller 3 continues to rotate. Under the action of the first guiding plate 52, the straws in the straw positioning grooves 32 are disengaged from the straw positioning grooves 32 along the first inclined guiding surface 54 and will not continue to rotate with the feeding roller 3. This achieves the one-by-one separation and feeding of the straws, ensuring the effective execution of the subsequent corrugated forming process.

[0031] This application defines the structure of the material distribution device by setting multiple suction tube positioning grooves 32 on the outer circumferential surface of the material distribution roller 3. During the downward rotation of the material distribution roller 3 driven by the rotating mechanism, the suction tubes in the feeding bin 2 will be inserted one by one into the corresponding suction tube positioning grooves 32 to achieve the one-to-one separation and feeding of the suction tubes, ensuring the effective progress of the subsequent corrugated forming process. In addition, the setting of the limiting plate 4 can limit the downward rotating suction tubes, preventing the suction tubes from detaching from the suction tube positioning grooves 32 during the downward rotation to the discharge chamber 51, thus affecting the effective progress of subsequent work. The overall device of this application is simple, can achieve the one-to-one separation and feeding of suction tubes, and has a fast feeding speed, which can achieve the separation and feeding of 800 suction tubes per minute.

[0032] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
