Description

Technical Field

[0001] The present invention relates to the field of marshmallow machines, and particularly to a marshmallow stick inserting device. Background Art

[0002] As a flavored snack food, marshmallows have the characteristics of soft, sticky and glutinous taste, and are sweet and delicious. They are a common dessert in modern people's lives. At present, the method of making marshmallows is still mainly semi-automatic production, that is, cotton sticks are extracted from a storage stick box or a stick storage cylinder, and then the sugar filaments generated by the marshmallow burner head are wound around them to make marshmallows. Long-term contact with cotton sticks is likely to cause hygiene problems.

[0003] Chinese Patent Document No. "CN213639535U" discloses a marshmallow automatic stick inserting device. The automatic stick inserting device includes a stick storage device, a stick pushing device and a stick feeding device for clamping and conveying cotton sticks. The stick feeding device includes a lifting mechanism, a horizontal moving mechanism, a clamping mechanism and a stick feeding seat. The clamping mechanism includes a steering motor. The stick feeding process is as follows: the clamping mechanism clamps the cotton stick. First, the clamping mechanism slides away from the stick storage device through the horizontal moving mechanism, so as to realize pulling the cotton stick out of the stick storage device; then the clamping mechanism realizes lifting the cotton stick to a suitable height position through the lifting mechanism, and the steering motor rotates at an angle to rotate the cotton stick to the vertical direction, so as to achieve the purpose of changing the direction of the cotton stick; the cotton stick is translated to the position of the stick inserting hole through the horizontal moving mechanism, and then the cotton stick is inserted downward into the stick inserting hole through the lifting mechanism.

[0004] This marshmallow automatic stick inserting device uses the horizontal moving mechanism to drive the clamping mechanism to move to realize the extraction of the cotton stick. After extraction, it is necessary to use the lifting mechanism to lift the cotton stick to a suitable height position to turn the cotton stick. The stick feeding needs to go through two translations, one rise and one fall. The stick feeding process is relatively complex, resulting in a slow stick feeding speed, and the structure of the stick feeding device is relatively complex, which is not conducive to reducing the cost of the marshmallow machine.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See Figure 1 and Figure 2, A marshmallow stick inserting device, comprising a stick storage device 2 that can screen out single marshmallow sticks 1, a stick pushing device 3 that can push one end of a single marshmallow stick 1 out of the stick storage device 2, and a stick feeding device 4 for conveying the marshmallow sticks 1. The stick pushing device 3 is located at one end of the stick storage device 2, and the stick feeding device 4 is located at the other end of the stick storage device 2; the stick feeding device 4 includes a feeding base 41, a stick pressing mechanism 42 that can vertically press down the marshmallow stick 1, and a stick receiving mechanism 43. The stick pressing mechanism 42 is fixed on the feeding base 41, and the stick receiving mechanism 43 is located below the stick pressing mechanism 42. The stick receiving mechanism 43 includes a horizontal feeding component 431 that can completely send out the marshmallow stick 1 from the stick storage device 2 and a turning component 432. The horizontal feeding component 431 and the turning component 432 are connected. The turning component 432 is rotatably connected to the feeding base 41. A number of marshmallow sticks 1 are placed in the stick storage device 2. The stick storage device 2 screens out single marshmallow sticks 1, and the stick pushing device 3 pushes one end of a single marshmallow stick 1 out of the stick storage device 2. When one end of the pushed-out marshmallow stick 1 reaches the position of the horizontal feeding component 431 of the stick receiving mechanism 43, the horizontal feeding component 431 sends the marshmallow stick 1 out horizontally until the marshmallow stick 1 completely leaves the stick storage device 2. Then, the turning component 432 of the stick receiving mechanism 43 turns the horizontal feeding component 431, and the horizontal feeding component 431 drives the marshmallow stick 1 to turn, so that the marshmallow stick 1 is vertically arranged. Finally, the stick pressing mechanism 42 vertically presses down the marshmallow stick 1 for inserting until the mechanical hand clamps the marshmallow stick 1, completing the automatic insertion of the marshmallow stick to the mechanical hand. There is no need for a special person or user to automatically pick up the marshmallow stick 1 and insert it onto the mechanical hand, achieving the purpose of automating the production of marshmallows. During the process of sending the marshmallow stick 1 away from the stick storage device 2, the relative position between the horizontal feeding component 431 and the stick storage device 2 remains unchanged. The horizontal feeding component 431 and the turning component 432 are connected. After the horizontal feeding component 431 completely sends out the marshmallow stick 1 from the stick storage device 2, the turning component 432 can directly turn the marshmallow stick 1. After the marshmallow stick 1 turns, it is inserted through the stick pressing mechanism 42. There is no need to lift the marshmallow stick 1 and translate the marshmallow stick 1 multiple times, which improves the speed of stick feeding. Moreover, since there is no need to set up a marshmallow stick lifting mechanism for the marshmallow stick, the structure of the stick feeding device is simplified, which is beneficial to reducing the cost of the marshmallow machine.

[0039] Preferably, refer to Figure 3, a signing base 41 is provided with a signing hole 412 at the bottom. The length and width of the signing hole 412 are both greater than or equal to the diameter of the cotton swab 1. By correcting the manipulator within a specified distance directly below the signing hole 412, it is convenient for the manipulator to be positioned, which is conducive to confirming the accurate position of the manipulator. At the same time, it is also conducive for the signing device 4 to confirm the accurate position for conveying the cotton swab 1. After the turning component 432 turns the cotton swab 1, the cotton swab 1 is located directly above the signing hole 441, and then the cotton swab 1 is vertically pressed down for insertion through the pressing mechanism 42 until the manipulator clamps the cotton swab 1. Further, a bottom plate 411 is provided above the signing hole 412. A through hole is formed in the middle of the bottom plate 411, and the diameter of the through hole of the bottom plate is greater than or equal to the diameter of the cotton swab 1. A signing photodetector 6 is provided on the bottom surface of the bottom plate 411, and the detection port of the signing photodetector 6 corresponds to the through hole of the bottom plate. The pressing mechanism 42 and the turning component 432 are respectively electrically connected to the master controller, and the manipulator is electrically connected to the master controller. Before the cotton swab 1 is vertically pressed down for insertion, the signing photodetector 6 cannot detect the cotton swab 1. During the process of the cotton swab 1 being vertically pressed down for insertion, when the signing photodetector 6 detects it, it transmits the detection signal to the master controller. The master controller feeds back a control signal to the manipulator, and the manipulator clamps the cotton swab 1 to complete automatic signing. After the manipulator withdraws the cotton swab 1, the signing photodetector 6 cannot detect the cotton swab 1 again, and the master controller does not receive the detection signal. The master controller feeds back a control signal to the pressing mechanism 42 and the turning component 432, and the pressing mechanism 42 and the turning component 432 reset.

[0040] Specifically, refer to Figures 1 to 4, the horizontal feeding component 431 includes a driving wheel 4311, a driven wheel 4312 and a feeding motor 4313. Both the driven wheel 4312 and the feeding motor 4313 are connected to the steering component 432. The output shaft of the feeding motor 4313 is connected to the driving wheel 4311. There is a gap between the driving wheel 4311 and the driven wheel 4312 for the cotton swab 1 to pass through. After the pushing device 3 pushes one end of a single cotton swab 1 out of the cotton swab storage device 2, one end of the cotton swab 1 enters the gap between the driving wheel 4311 and the driven wheel 4312. At this time, the feeding motor 4313 starts, and the output shaft of the feeding motor 4313 drives the driving wheel 4311 to rotate. The cotton swab 1 is horizontally fed through the gap between the driving wheel 4311 and the driven wheel 4312 until the cotton swab 1 completely leaves the cotton swab storage device 2. Preferably, the steering component 432 includes a connecting plate 4321, a connecting bar 4322 and a steering motor 4323. The steering motor 4323 is fixed on the cotton swab feeding base 41. The rotating shaft of the steering motor 4323 is connected to one end of the connecting bar 4322. The other end of the connecting bar 4322 is connected with a connecting plate 4321. The driven wheel 4312 is connected to the side of the connecting plate 4321 close to the connecting bar 4322, and the feeding motor 4313 is connected to the other side of the connecting plate 4321. There is a feeding through hole on the connecting bar 4322 for the cotton swab 1 to pass through, and the feeding through hole corresponds to the gap. The cotton swab 1 is horizontally fed through the gap between the driving wheel 4311 and the driven wheel 4312 and enters the through hole of the connecting bar 4322. After the cotton swab 1 completely leaves the cotton swab storage device 2, the steering motor 4323 starts, and the rotating shaft of the steering motor 4323 drives the connecting bar 4322 to rotate. The cotton swab 1 located in the through hole of the connecting bar 4322 is turned until the cotton swab 1 is vertically arranged. Further, the steering component 432 further includes a detection plate 4324 connected to the connecting bar 4322. The detection plate 4324 is perpendicular to the axis of the driving wheel 4311 and parallel to the center line connecting the centers of the driving wheel 4311 and the driven wheel 4312. The steering motor 4323 is electrically connected to the main controller. A steering photodetector 5 is also provided at the bottom of the cotton swab feeding base 41. When the steering motor 4323 turns, the detection plate 4324 rotates with the steering motor 4323. When the steering photodetector 5 detects the detection plate 4324, it transmits the detection signal to the main controller. The main controller feeds back a control signal to the steering motor 4323, and the steering motor 4323 will stop rotating. The detection plate 4324 stops at the position of the steering photodetector 5. At this time, the gap between the driving wheel 4311 and the driven wheel 4312 is aligned with the cotton swab outlet position of the cotton swab storage device 2, which is the position where the cotton swab 1 is horizontally fed out.

[0041] Such as Figure 1As shown, the label pressing mechanism 42 includes a label pressing slide bar 421, a label pressing slider 422, a lifter 423, and a pressing piece 425. The label pressing slider 422 is slidably connected to the label pressing slide bar 421. The label pressing slide bar 421 and the lifter 423 are fixed on the label feeding base 41. The pressing piece 425 is connected to the label pressing slider 422 and the lifter 423 respectively. Optionally, the pressing piece 425 is connected to the lifting seat 424, and the pressing piece 425 is connected to the label pressing slider 422 and the lifter 423 respectively through the lifting seat 424. Specifically, refer to Figure 2 , the lifter 423 includes two belt pulleys 4231, a conveyor belt 4232, and a lifting motor 4233. One of the belt pulleys 4231 is connected to the bottom end of the label feeding base 41, and the other belt pulley 4231 is connected to the rotating shaft of the lifting motor 4233. The lifting motor 4233 is connected to the top end of the label feeding base 41. The two belt pulleys 4231 are arranged on the same vertical line, and the two belt pulleys 4231 are connected by the conveyor belt 4232. The lifting seat 424 is connected to the conveyor belt 4232 through a fixing clip. When the lifting motor 4233 drives the belt pulley 4231 to rotate, it will drive the lifting seat 424 to move up and down, and the pressing piece 425 will move up and down with the lifting seat 424. When the pressing piece 425 descends, it will press down the cotton swab 1 and insert it into the manipulator. When the pressing piece 425 ascends, it will reset. The lifting seat 424 is connected to the label pressing slider 422, and the lifting slider 422 is slidably connected to the label pressing slide bar 421, thus ensuring that the lifting seat 424 slides more smoothly. Preferably, the belt drive mode between the belt pulley 4231 and the conveyor belt 4232 can be replaced by the chain drive mode of a sprocket and a chain. Preferably, to improve the smoothness of transmission and the accuracy of transmission, the lifter 423 can be replaced by a linear guide rail or a pneumatic slide table.

[0042] Such as Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the cotton swab storage device 2 includes a cotton swab storage box 21 and a swab outlet groove 22. The swab outlet groove 22 is located below the cotton swab storage box 21. The opposite side walls of the cotton swab storage box 21 are arranged in a V shape, and an outlet 23 is formed at the bottom of the two side walls. The groove wall of the swab outlet groove 22 is fixedly connected to the side wall. The groove width of the swab outlet groove 22 is adapted to the diameter of the cotton swab 1. The swab outlet groove 22 is parallel to the cotton swab 1. When a number of cotton swabs 1 are placed in the cotton swab storage box 21, the cotton swabs 1 fall from the outlet 23 into the swab outlet groove 22 under the action of their own weight. Since the groove width of the swab outlet groove 22 is adapted to the diameter of the cotton swab 1, that is, the groove width of the swab outlet groove 22 is equal to the diameter of the cotton swab 1 or the groove width of the swab outlet groove 22 is less than the sum of the diameters of two cotton swabs 1, only one cotton swab 1 falls into the swab outlet groove 22, thus achieving the purpose of screening out a single cotton swab 1. Therefore, after the cotton swab storage device 2 screens out a single cotton swab 1 and it falls into the swab outlet groove 22, a swab pushing device 3 fixed on one side of the cotton swab storage device 2 pushes the cotton swab 1 in the swab outlet groove 22 to the other side of the cotton swab storage device 2, and pushes one end of the single cotton swab 1 out of the cotton swab storage device 2. Since the opposite side walls of the cotton swab storage box 21 are arranged in a V shape and an outlet 23 is formed at the bottom of the two side walls, under the action of the inclined side walls, it is beneficial to guide the cotton swabs 1 and achieve the function of guiding and outputting the cotton swabs 1. In addition, it avoids the problem that there are dead corners in the cotton swab storage box 21, causing some cotton swabs 1 to remain in the cotton swab storage box 21 without being used.

[0043] Further, the cotton swab storage device 2 further includes a swab outlet roller 24 and a rotator 25. A through hole is provided on the cotton swab storage box 21. One end of the swab outlet roller 24 passes through the through hole and is connected to the rotating end of the rotator 25. The other end of the swab outlet roller 24 is connected to the cotton swab storage box 21. The swab outlet roller 24 is parallel to the cotton swab 1. Specifically, one end of the swab outlet roller 24 passes through the through hole and is connected to the rotating end of the rotator 25. The other end of the swab outlet roller 24 is connected to the cotton swab storage box 21 through a bearing. The swab outlet roller 24 is close to the outlet 23 and is located on one side of the swab outlet groove 22. Then, by rotating the swab outlet roller 24, a number of cotton swabs 1 in the cotton swab storage box 21 are agitated to move, so that it is convenient for the cotton swabs 1 to fall into the swab outlet groove 22 on one side of the swab outlet roller 24.

[0044] As Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown in the figure, the cotton swab pushing device 3 includes a fixed seat 31, a sliding seat 32 and a cotton swab pushing motor 33. A cotton swab pushing slider 322 is provided at the bottom of the sliding seat 32. The cotton swab pushing slider 322 is slidably connected to the cotton swab pushing rod 311 of the fixed seat 31. One end of the sliding seat 32 close to the cotton swab storage device 2 is provided with a cotton swab pushing plate 321. The other end of the sliding seat 32 is connected to the cotton swab pushing motor 33. Driven by the cotton swab pushing motor 33, the sliding seat 32 connected to the cotton swab pushing motor 33 slides, so that the cotton swab pushing plate 321 of the sliding seat 32 slides. When the cotton swab pushing plate 321 slides, it pushes the cotton swabs in the cotton swab outlet groove 22.

[0045] Furthermore, the cotton swab pushing device 3 further includes a motor bracket 34, a rotating rod 35 and a connecting rod 36. The cotton swab pushing motor 33 is vertically fixed on the motor bracket 34. One end of the rotating rod 35 is connected to the rotating shaft of the cotton swab pushing motor 33. The other end of the rotating rod 35 is connected to one end of the connecting rod 36. The other end of the connecting rod 36 is hinged on the sliding seat 32. Specifically, the cotton swab pushing motor 33 is vertically fixed on the motor bracket 34, that is, the axis of the rotating shaft of the cotton swab pushing motor 33 is perpendicular to the axis of the cotton swab pushing rod 311, that is, the axis of the rotating shaft of the cotton swab pushing motor 33 is perpendicular to the moving direction of the sliding seat 32. A rotating rod 35 is connected to the rotating shaft of the cotton swab pushing motor 33, and the rotating rod 35 and the sliding seat 32 are connected by a connecting rod 36. Then when the cotton swab pushing motor 33 rotates, the purpose of the sliding seat 32 sliding back and forth can be achieved, and further the reciprocating pushing action of the cotton swab pushing plate 321 is realized.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
