Description

Technical Field

[0002] Cotton candy is currently a popular dessert, and cotton candy machines are the equipment used to make it. These machines are commonly found in shopping malls, amusement parks, cinemas, and scenic spots. In the relevant technology, when cotton candy needs to be made, workers pour the sugar from the storage box directly into the feed inlet of the furnace head. The sugar is heated by the furnace head and turns into sugar threads. These threads are then output from the furnace head. Workers then take cotton candy sticks from the stick box and place them into the furnace head to wrap around the sugar threads produced there, causing the threads to adhere to the sticks and ultimately forming the cotton candy product.

[0003] Regarding the aforementioned technologies, the inventors believe that manually removing marshmallow sticks from the stick box and then holding the sticks to place them on the stove for wrapping and collecting the sugar strands not only increases the labor intensity of workers but also takes a long time and has a low degree of automation.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an automatic stick feeding device for a cotton candy machine. The automatic stick feeding device is installed inside the bottom of the cotton candy machine and located below the intelligent robotic arm device, so as to automatically feed the round stick tube 6 upward into the intelligent robotic arm device.

[0025] Specifically, refer to Figure 1 In this embodiment, the automatic stick feeding device includes a base 1, a fixed stick feeding hopper 2, a stick storage assembly, a roller 21, a stick feeding drive assembly, a stick tube positioning assembly, a motor bracket 4, a lifting guide rail 41, a stick feeding slider 42, a stick feeding clamping mechanism, and a stick feeding lifting assembly. The base 1 is installed inside the bottom side of the cotton candy machine; the fixed stick feeding hopper 2 is installed on top of the base 1 and is used to store the round stick tubes 6; the stick storage assembly is movably disposed within the fixed stick feeding hopper 2, and a stick feeding port is provided at the bottom front side of the fixed stick feeding hopper 2. The arrangement of the stick storage assembly facilitates the smooth and orderly sliding of the round stick tubes 6 from the fixed stick feeding hopper 2 into the stick feeding port.

[0026] More specifically, refer to Figure 1 In this embodiment, the rod storage assembly includes a movable rod outlet 3, a vibration motor, a gear set, and a guide plate. The movable rod outlet 3 is rotatably mounted inside the fixed rod outlet 2 via a fixed shaft 31. Rotation of the fixed shaft 31 causes the movable rod outlet 3 to swing, and the round rod tubes 6 are stored between the fixed rod outlet 2 and the movable rod outlet 3. The vibration motor is fixedly mounted inside the fixed rod outlet 2. The gear set consists of two meshing gears, which are respectively mounted on the output end of the vibration motor and on the fixed shaft.

[0027] When the vibration motor is started, the output end of the vibration motor drives the fixed shaft 31 to rotate through the gear set, so that the fixed shaft 31 can drive the movable rod bucket 3 to swing effectively inside the fixed rod bucket 2, thereby facilitating the subsequent rod feeding process.

[0028] The guide plate is installed on the inner side of the fixed rod outlet 2. The guide plate is located above the rod outlet and is designed to be inclined downwards towards the movable rod outlet 3. At the same time, the guide plate and the bottom of the movable rod outlet 3 cooperate with each other to block the round rod tube 6. Then, under the drive of the vibration motor, the movable rod outlet 3 rotates through the fixed shaft 31, which helps the round rod tube 6 to slide neatly and smoothly down into the rod outlet area at the bottom along the gap between the guide plate and the movable rod outlet 3.

[0029] Additionally, refer to Figure 1 and Figure 2 In this embodiment, the roller 21 is rotatably mounted in the rod outlet at the bottom front side of the fixed rod outlet hopper 2, and a rod feeding slot 211 is provided on the outer side of the roller 21 shaft. The rod feeding slot 211 cooperates with the round rod tube 6 to facilitate the storage of the round rod tube 6. At the same time, the rod dispensing drive assembly is disposed between the fixed rod outlet hopper 2 and the roller 21 to drive the roller 21 to rotate.

[0030] When the gap between the bar feeding slot 211 on the roller 21 and the guide plate and the movable bar dispensing bucket 3 corresponds to each other, a round bar tube 6 slides into the bar feeding slot 211 along the gap. Then, under the action of the bar dispensing drive assembly, the roller 21 is driven to rotate, so that the bar feeding slot 211 and the bar dispensing port coincide with each other. This allows the round bar tube 6 to slide out of the fixed bar dispensing bucket 2 along the bar dispensing port, thereby achieving the bar dispensing effect of the round bar tube 6.

[0031] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the rod-discharging drive assembly includes a mounting frame 22, roller bearings 23, a drive rod 24, and a rod-discharging motor 25. Two mounting frames 22 are provided, symmetrically mounted on the two outer sides of the fixed rod-discharging bucket 2. Two roller bearings 23 are provided, each mounted inside one of the two mounting frames 22, and both ends of the roller 21 are rotatably connected to the two roller bearings 23, making the rotation of the roller 21 smoother and faster. One end of the drive rod 24 is mounted at one end of the roller 21, and the other end of the drive rod 24 extends outside the fixed rod-discharging bucket 2. The rod-discharging motor 25 is mounted on one side of the fixed rod-discharging bucket 2, and the output end of the rod-discharging motor 25 is fixedly connected to the end of the drive rod 24 extending outside the fixed rod-discharging bucket 2.

[0032] When the rod-exiting motor 25 is started, the output end of the rod-exiting motor 25 drives the drive rod 24 to rotate, which in turn drives the roller 21 to rotate. Thus, a round rod tube 6 is conveyed out of the rod outlet of the fixed rod-exiting bucket 2 through the rod-feeding slot 211 on the roller 21, thereby achieving the rod-exiting effect of the round rod tube 6.

[0033] In addition, refer to Figure 1 and Figure 2 In this embodiment, the rod positioning assembly is disposed on the top of the base 1. The rod positioning assembly cooperates with the roller 21 to effectively position the round rod 6 that is conveyed out of the rod feeding slot 211. Specifically, in this embodiment, the rod positioning assembly includes a positioning seat 11, a positioning frame 12, and a rod lever 13. The positioning seat 11 and the positioning frame 12 are respectively installed on the top of the base 1. The positioning seat 11 and the positioning frame 12 are respectively located at the front ends of the fixed rod feeding bucket 2, and the rear sides of the positioning seat 11 and the positioning frame 12 respectively abut against the front side of the fixed rod feeding bucket 2.

[0034] The rod lever 13 is hinged to the side of the positioning seat 11 away from the fixed rod bucket 2 by a torsion spring. The rod lever 13 has a U-shaped structure, with one end located on the side of the positioning seat 11 away from the positioning frame 12; the other end is located between the positioning seat 11 and the positioning frame 12, pressing against the top of the base 1. When downward force is applied to the end of the rod lever 13 on the positioning seat 11 away from the positioning frame 12, the rod lever 13 swings downward around the hinge point, while the other end swings upward, thus rotating the rod lever 13 from a horizontal to a vertical orientation. When the pressure on the rod lever 13 is released, the torsion spring causes the vertical rod lever 13 to rotate back to a horizontal orientation, thus resetting the rod lever 13.

[0035] Meanwhile, positioning slots 14 are provided on the top of the end of the rod tube lever 13 located between the positioning seat 11 and the positioning frame 12, on the top of the positioning seat 11, and on the top of the positioning frame 12. These positioning slots 14 are located on the same straight line to form a positioning channel that cooperates with the round rod tube 6, which can position and place the round rod tube 6 that slides out from the rod feeding slot 211.

[0036] Preferably, inclined portions 15 are provided on the side of the rod tube lever 13 near the top of the fixed rod hopper 2, on the side of the positioning seat 11 near the top of the fixed rod hopper 2, and on the side of the positioning frame 12 near the top of the fixed rod hopper 2. The inclined surfaces of these inclined portions 15 are designed to gradually rise towards the side of the fixed rod hopper 2. In this way, when the round rod tube 6 slides out from the rod feeding slot 211, the round rod tube 6 can accurately slide into the interior of the positioning pipe along these inclined portions 15, thereby achieving an effective guiding and sliding effect on the round rod tube 6.

[0037] Additionally, refer to Figure 1 and Figure 2 In this embodiment, the motor bracket 4 is fixedly installed on one side of the top of the base 1; the lifting guide rail 41 is vertically installed on the top of the motor bracket 4; the rod feeding slider 42 is slidably installed on one side of the lifting guide rail 41; the rod feeding clamping mechanism is located on the side of the rod feeding slider 42 away from the lifting guide rail 41, and the rod feeding clamping mechanism cooperates with the rod tube positioning component to vertically clamp the round rod tube 6 positioned in the positioning pipe; the rod feeding lifting component is located between the motor bracket 4 and the lifting guide rail 41, and the rod feeding lifting component cooperates with the rod feeding slider 42 to drive the rod feeding slider 42 to achieve the effect of lifting and lowering on the lifting guide rail 41, thereby facilitating the automatic upward transport of the vertically clamped round rod tube 6 to the intelligent robotic arm device of the cotton candy machine for the steps of winding and collecting sugar threads.

[0038] The structure of the bar feeding lifting assembly and the bar feeding clamping mechanism is described in detail below:

[0039] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the bar feeding and lifting assembly includes a bar feeding motor 43, a driving synchronous pulley 44, a synchronous pulley bracket 45, a driven synchronous pulley 46, a synchronous belt 47, and connecting members. The bar feeding motor 43 is mounted on one side of the motor bracket 4; the driving synchronous pulley 44 is fixedly mounted on the output end of the bar feeding motor 43 to drive its rotation; the synchronous pulley bracket 45 is mounted on one side of the top of the lifting guide rail 41; the driven synchronous pulley 46 is rotatably mounted on the synchronous pulley bracket 45; the synchronous belt 47 is a belt with its ends disconnected, wound between the driving synchronous pulley 44 and the driven synchronous pulley 46; the bar feeding slider 42 is connected to both ends of the synchronous belt 47 via connecting members.

[0040] More specifically, the connector consists of two connecting blocks 48, which are symmetrically installed on the rear side of the bar feeding slider 42. The beginning and end of the timing belt 47 are respectively installed on the two connecting blocks 48, thereby making the timing belt 47 and the bar feeding slider 42 firmly connected together.

[0041] Preferably, three pulleys 49 are rotatably mounted on the rear side of the rod feeding slider 42, and these pulleys 49 abut against both sides of the lifting guide rail 41 respectively; the arrangement of these pulleys 49 not only allows the rod feeding slider 42 to slide more smoothly on the lifting guide rail 41, but also effectively guides and limits the rod feeding slider 42.

[0042] When the bar feeding motor 43 is started, the output end of the bar feeding motor 43 drives the active synchronous wheel 44 to rotate. Under the action of the driven synchronous wheel 46 and the synchronous belt 47, the synchronous belt 47 can drive the bar feeding slider 42 to slide up and down on the lifting guide rail 41, thereby realizing the lifting and moving of the bar feeding clamping mechanism.

[0043] Specifically, refer to Figure 1 and Figure 4 In this embodiment, the rod feeding clamping mechanism includes a tube clamping bracket 5, a top abutment 51, a swing base plate 52, a rod clamp 53, an elliptical cam block 54, a rod clamping motor 55, and a rod support assembly. One side of the tube clamping bracket 5 is fixedly mounted on the side of the rod feeding slider 42 opposite to the lifting guide rail 41; the top abutment 51 is mounted at the bottom end of the side of the tube clamping bracket 5 opposite to the rod feeding slider 42, and the top abutment 51 cooperates with the end of the rod feeding lever 13 located on the positioning seat 11 opposite to the positioning frame 12.

[0044] When the rod-feeding slider 42 descends, it drives the clamping support 5 to descend as well. This causes the bottom abutment 51 of the clamping support 5 to apply downward pressure to one end of the rod-tube lever 13, causing the rod-tube lever 13 to rotate and swing. The other end of the rod-tube lever 13 then tilts up, rotating the round rod 6, which is positioned inside the positioning pipe, from a horizontal position to a vertical position. When one side of the rod-tube lever 13 is vertically pressed against one side of the clamping support 5, the positioning slot 14 on the rod-tube lever 13 holds the vertically placed round rod 6 against one side of the clamping support 5. At the same time, the bottom of the vertical rod-tube lever 13 supports the bottom end of the round rod 6, thereby lifting the round rod 6 out of the positioning pipe.

[0045] Meanwhile, there are two swing base plates 52, one end of which is symmetrically hinged to the top of the clamping bracket 5; there are two rod clamps 53, which are respectively installed on the two swing base plates 52, and both rod clamps 53 are spring pieces with a certain elasticity, so as to extend out of the clamping bracket 5; and when the ends of the two rod clamps 53 are closed together, they can firmly clamp the round rod tube 6.

[0046] The elliptical cam block 54 is rotatably mounted on the top of the pipe clamping bracket 5. The elliptical cam block 54 is located between the rear ends of the two pipe clamps 53, and the outer side of the elliptical cam block 54 abuts against the inner side of the two pipe clamps 53 respectively. The clamping rod motor 55 is mounted on the bottom of the pipe clamping bracket 5, and the output end of the clamping rod motor 55 is fixedly connected to the elliptical cam block 54.

[0047] When the rod lever 13 lifts the round rod 6, the clamping rod motor 55 is activated. The output end of the clamping rod motor 55 drives the elliptical cam block 54 to rotate. The long ends on both sides of the elliptical cam block 54 abut against the inner rear ends of the two rod clamps 53, causing the rear ends of the two rod clamps 53 to open up to each other, while the front ends of the two rod clamps 53 close up to each other, thereby effectively clamping and fixing the lifted round rod 6.

[0048] When the clamping rod motor 55 drives the elliptical cam block 54 to reset in the opposite direction, the short ends on both sides of the elliptical cam block 54 abut against the inner rear ends of the two rod clamps 53 respectively. In this way, the front ends of the two rod clamps 53 are stretched apart by their own elasticity, thereby releasing the round rod tube 6.

[0049] Furthermore, the rod-tube support assembly is located inside the tube clamp bracket 5, and this rod-tube support assembly cooperates with the elliptical cam block 54 to effectively support the bottom of the vertical round rod-tube 6. Specifically, refer to... Figure 1 and Figure 5 In this embodiment, the rod support assembly includes a hook rod 56, an abutment portion 561, and a hook rod portion 562. The hook rod 56 is hinged to the inner side of the clamping bracket 5 via a torsion spring. The abutment portion 561 is mounted on the top of the hook rod 56, and a bracket hole is provided at the top of the clamping bracket 5. The abutment portion 561 extends out of the top of the clamping bracket 5 along the bracket hole, and abuts against the long end of the elliptical cam block 54.

[0050] The hook rod part 562 is installed on one side of the bottom end of the hook rod 56, and a through slot 131 is provided on the end of the rod tube lever 13 located on the positioning seat 11 away from the positioning frame 12. The through slot 131 cooperates with the hook rod part 562. When the two short ends of the elliptical cam block 54 abut against the inner rear ends of the two rod tube clamps 53 respectively, the long end of one side of the elliptical cam block 54 abuts against the abutting part 561 on the top end of the hook rod 56. At this time, the hook rod 56 is pulled by the torsion spring, so that the hook rod part 562 at the bottom end of the hook rod 56 is located inside the clamping bracket 5.

[0051] When the elliptical cam block 54 rotates, the long end of one side of the elliptical cam block 54 moves away from the abutment part 561. Under the restoring elastic action of the torsion spring, the hook part 562 on the bottom end of the hook rod 56 extends out of the outside of the clamping tube bracket 5 and extends into the through slot 131 of the rod tube lever 13. Then, driven by the rising of the rod feeding slider 42, the hook part 562 effectively supports the bottom end of the vertical round rod tube 6, thereby preventing the vertical round rod tube 6 from falling.

[0052] Therefore, this application, by setting up an automatic stick feeding device that consists of a base 1, a fixed stick feeding bucket 2, a stick storage assembly, a roller 21, a stick feeding drive assembly, a stick tube positioning assembly, a motor bracket 4, a lifting guide rail 41, a stick feeding slider 42, a stick feeding clamping mechanism, and a stick feeding lifting assembly working together, can automatically feed the round stick tube 6 in the fixed stick feeding bucket 2 upwards to the intelligent robotic arm device of the cotton candy machine for winding and collecting the sugar threads. By setting up this device, the effect of automatic stick feeding can be achieved, which not only reduces the labor intensity of the workers, but also shortens the time spent and has a high degree of automation.

[0053] The implementation principle of the automatic stick-feeding device for a cotton candy machine according to an embodiment of this application is as follows:

[0054] When it is necessary to automatically convey the round rod tube 6 upward to the intelligent robotic arm device of the cotton candy machine, the round rod tube 6 in the fixed rod hopper 2 is first neatly and smoothly slid into the rod feeding slot 211 of the roller 21 by using the rod storage assembly. Then the rod dispensing motor 25 is started, and the rod dispensing motor 25 drives the roller 21 to rotate, so that the round rod tube 6 slides out of the rod dispensing slot 211 from the rod feeding slot 211 outside the rod dispensing port of the fixed rod dispensing hopper 2.

[0055] Then the round bar tube 6 slides down along the inclined part 15 on the bar tube positioning assembly into the positioning pipe; then the bar feeding motor 43 is started, and the bar feeding motor 43 drives the bar feeding slider 42 to move downward, so that the bottom abutment 51 of the clamping bracket 5 applies downward pressure to the top of one end of the bar tube lever 13, so that the bar tube lever 13 drives the round bar tube 6 to stand up and be sent into the space between the two bar tube clamps 53.

[0056] Then start the clamping rod motor 55. The clamping rod motor 55 drives the elliptical cam block 54 to rotate. The elliptical cam block 54 drives the front ends of the two rod clamps 53 to close together to clamp the round rod tube 6. At the same time, the abutting part 561 at the top of the hook rod 56 is not abutted by the elliptical cam block 54. Under the restoring elasticity of the torsion spring, the hook part 562 at the bottom of the hook rod 56 extends out from the bottom of the clamping tube bracket 5 to extend into the through slot 131 of the rod tube lever 13.

[0057] Then, the bar-feeding motor 43 drives the bar-feeding slider 42 to slide upward, so that the hook part 562 on the hook bar 56 hooks the bottom of the round bar tube 6, and sends the round bar tube 6 to the designated position; when it is sent to the designated position, the intelligent robotic arm device clamps the top of the round bar tube 6, and finally the bar-clamping motor 55 drives the elliptical cam block 54 to rotate, so as to release the bar clamp 53 and the hook bar 56, thereby completing the bar-feeding process.
