Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and more specifically, to a roller lowering device for a cotton candy machine. Background Technology

[0002] Marshmallows are made by placing solid sugar in a rotating disc, heating it to melt it into syrup, and then rapidly rotating the disc to fling the syrup out by centrifugal force. The syrup is then cooled by air to form sugar strands, which are then wound around a rod (usually a wooden stick) to form an edible marshmallow.

[0003] With the continuous advancement of automation technology, food processing equipment has become widespread in various industries, and fully automatic cotton candy machines have replaced traditional manual cotton candy machines in the market, achieving excellent results.

[0004] Currently, the invention patent with patent application number CN202220331510.7 discloses a roller lowering mechanism for a cotton candy machine. After the roller falls from the storage roller into the vertical roller groove, the roller is directly flipped. This roller lowering scheme requires the roller to be held by the robotic arm and completely detached from the vertical roller groove before the next roller can be controlled to fall. The roller lowering speed is low, so there is still room for improvement. Summary of the Invention

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This invention provides a lower roller device for a cotton candy machine, such as... Figure 1-5 As shown, the system includes: a frame 1, a storage mechanism 2 for storing rods, a rod retrieval mechanism 3 for retrieving rods from the storage mechanism 2, a push mechanism 4 for pushing out the rods retrieved from the rod retrieval mechanism 3, a clamping and rotating mechanism 5 for gripping and rotating the pushed-out rods, a feeding mechanism 6 for feeding the rotated rods, and a controller 7. The storage mechanism 2 is mounted on the frame 1. The rod retrieval mechanism 3 is located inside the storage mechanism 2. The push mechanism 4 is mounted on the frame 1 and located below the rod retrieval mechanism 3. The clamping and rotating mechanism 5 is mounted on the frame 1 and located at the rod outlet of the rod retrieval mechanism 3. The feeding mechanism 6 is mounted on the frame 1 and located to one side of the clamping and rotating mechanism 5. The storage mechanism 2, the rod retrieval mechanism 3, the push mechanism 4, the clamping and rotating mechanism 5, and the feeding mechanism 6 are all electrically connected to the controller 7.

[0028] In practical applications, the rollers in the storage mechanism 2 are sequentially removed by the roller-picking mechanism 3 and placed into the roller-pushing mechanism 4. The roller-pushing mechanism 4 pushes the rollers to the clamping and rotating mechanism 5. The clamping and rotating mechanism 5 clamps the rollers and rotates them. After rotation, the rollers are attached to the roller-picking mechanism 3 and output through the roller-picking mechanism 3. Since the rollers are pushed to the clamping and rotating mechanism 5 by the roller-pushing mechanism 4, the roller-picking mechanism 3 can pick up the next roller. This moves the rollers to the feeding end of the clamping and rotating mechanism 5 without affecting the clamping, rotating, and discharging of subsequent rollers, thereby improving the roller discharging efficiency. In this embodiment, the controller 7 is a microcontroller; in other embodiments, the controller 7 can also be an MCU, PC, etc.

[0029] Further, the roller storage mechanism 2 includes: a roller storage plate 21, a stirring rod 22, and a stirring motor 23; the roller storage plate 21 is mounted on the frame 1; a feeding port is provided at the upper end of the roller storage plate 21; a roller body outlet is provided at the lower end of the roller storage plate 21; the stirring rod 22 is mounted at the roller body outlet and one end is rotatably connected to the roller storage plate 21, and the other end is fixed to the output end of the stirring motor 23; the stirring motor 23 is mounted on the roller storage plate 21; the roller taking mechanism 3 is mounted on the roller storage plate 21 and located below the roller body outlet; the stirring motor 23 is electrically connected to the controller 7. In practical applications, the storage tray 21 stores a large number of rods, and the length of the storage tray 21 is set to be close to the length of the rods according to actual needs, and the lower end is set as an inclined surface. The rods move to the rod outlet with gravity. The stirring rod 22 is set horizontally and divides the rod outlet into two sections, each of which allows only one rod to pass horizontally. The cross-section of the stirring rod 22 is a regular hexagon. While rotating, it presses down the rod on one side and lifts up the rod on the other side, thereby preventing two rods from falling into the rod retrieval mechanism 3 at the same time.

[0030] Optionally, the stick-retrieving mechanism 3 includes: a stick-retrieving motor 31, a driving rubber-coated wheel 32, a driven rubber-coated wheel 33, a rotating rod 34, and several paddles 35; U-shaped grooves corresponding to and adapted to the stick body are formed on the several paddles 35; the several paddles 35 are evenly arranged on the rotating rod 34; one end of the rotating rod 34 is rotatably connected to the stick-storing mechanism 2, and the other end is fixed to the driven rubber-coated wheel 33; the driven rubber-coated wheel 33 is rotatably connected to the stick-storing mechanism 2; the stick-retrieving motor 31 is mounted on the frame 1; the driving rubber-coated wheel 32 is mounted on the output end of the stick-retrieving motor 31; the driving rubber-coated wheel 32 is in contact with the driven rubber-coated wheel 33; the stick-retrieving motor 31 is electrically connected to the control system. In practical applications, when the stick needs to be lowered, the stick-picking motor 31 drives the active rubber-coated wheel 32 to rotate. Since the active rubber-coated wheel 32 and the driven rubber-coated wheel 33 are in contact, the driven rubber-coated wheel 33 rotates with the active rubber-coated wheel 32 under the action of friction. At this time, the rotating rod 34 rotates with the driven rubber-coated wheel 33, so the several paddles 35 on the rotating rod 34 rotate. When the U-shaped groove on the paddles 35 is aligned with the stick's outlet, the stick falls and enters the U-shaped groove. After the paddles 35 rotate until the U-shaped groove reaches the push stick assembly, the stick falls into the push stick assembly by gravity. The design of the active rubber-coated wheel 32 and the driven rubber-coated wheel 33 ensures that when the stick is stuck at the paddle 35, the active rubber-coated wheel 32 will not be stuck due to the influence of the driven rubber-coated wheel 33, thus avoiding the phenomenon of the stick-picking motor 31 burning out due to the stick being stuck.

[0031] In practical applications, a clamping spring is provided on the frame to push the active rubber-coated wheel 32 against the driven rubber-coated wheel 33. Under the action of the clamping spring, the active rubber-coated wheel 32 is pressed against the driven rubber-coated wheel 33, thereby increasing the friction between the active rubber-coated wheel 32 and the driven rubber-coated wheel 33 and preventing the active rubber-coated wheel 32 from spinning idly due to poor contact between the active rubber-coated wheel 32 and the driven rubber-coated wheel 33.

[0032] Optionally, the pusher mechanism 4 includes: a pusher frame 41, a pusher motor 42, a transmission assembly 43, a pusher block 44, and a guide rod 45; the pusher frame 41 is mounted on the frame 1 and located below the pusher mechanism 3; the pusher motor 42 is mounted on the frame 1; the guide rod 45 is mounted on the pusher frame 41 and is horizontally positioned; the pusher block 44 is slidably connected to the guide rod 45; one end of the transmission assembly 43 is fixed to the output end of the pusher motor 42, and the other end is hinged to the pusher block 44; a first sensor 8 is mounted on the pusher frame 41; the first sensor 8 and the pusher motor 42 are both electrically connected to the controller 7. In practical applications, the transmission assembly 43 includes a rocker arm and a connecting rod. One end of the rocker arm is fixed to the output end of the pusher motor 42, and the other end is rotatably connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the push block 44. After the rod falls into the rod holder 41, the first sensor 8 senses the rod and sends the information to the controller 7. The controller 7 then controls the pusher motor 42 to start, causing the rocker arm to rotate, which in turn causes the connecting rod to swing. Under the action of the connecting rod, the push block 44 reciprocates linearly along the guide rod 45, thereby pushing the rod that has fallen onto the rod holder 41 to the clamping and rotating mechanism 5. In this embodiment, the first sensor 8 is a laser sensor. In other embodiments, it can also be an infrared sensor, a proximity sensor, or other sensors capable of sensing the position of the rod.

[0033] Furthermore, a lifting protrusion 9 is provided in the middle of the rod holder 41; and a pressure plate 10 for limiting the position of the rod is provided on the push block 44. In practical applications, the lifting protrusion 9 is an inclined block, with its higher end tilted towards the clamping and rotating mechanism 5. Therefore, after the stick falls into the stick holder 41, the stick is affected by the lifting protrusion 9, and the end of the stick near the clamping and rotating mechanism 5 is raised. The pressure plate 10 can restrict the position of the end of the stick away from the clamping and rotating mechanism 5, thus keeping the end of the stick near the clamping and rotating mechanism 5 raised during the process of moving to the clamping and rotating mechanism 5 by the push block 44. After the stick moves to the clamping and rotating mechanism 5, the push block 44 retracts, and the stick loses the restriction of the pressure plate 10. Due to the change in the position of the stick, the end of the stick away from the clamping and rotating mechanism 5 is raised by the lifting protrusion 9, while the end near the clamping and rotating mechanism 5 sinks, making it easier to enter the clamping and rotating mechanism 5 and improving the clamping stability of the clamping and rotating mechanism 5.

[0034] Furthermore, a limit switch 11 is provided at one end of the roller placement frame 41 near the roller pusher motor 42; the limit switch 11 is electrically connected to the controller 7. In practical applications, when the pusher block 44 is reset, the pusher block 44 contacts the limit switch 11 and triggers the limit switch 11. The controller 7 receives the information from the limit switch 11 and controls the roller take-up motor 31 to rotate, causing the roller to fall into the roller placement frame 41, thereby realizing automatic feeding.

[0035] Further, the clamping and rotating mechanism 5 includes: a rotary motor 51, a rotating shaft 52, a first friction block 53, a second friction block 54, a spring 55, a first magnetic block 56, and a second magnetic block 57; the rotary motor 51 is mounted on the frame 1; the rotating shaft 52 is mounted on the output end of the rotary motor 51; the first friction block 53 is mounted on the rotating shaft 52; the second friction block 54 is slidably mounted on the rotating shaft 52; the spring 55 is sleeved on the rotating shaft 52; one end of the spring 55 is fixed to the side of the second friction block 54 away from the first friction block 53, and the other end is fixed to the frame 1; the first magnetic block 56 is mounted on the frame 1; the second magnetic block 57 is mounted on the second friction block 54; the first magnetic block 56 can attract the second magnetic block 57; the rotary motor 51 is electrically connected to the control system. In practical applications, the rotary motor 51 drives the rotary shaft 52 to rotate, thereby causing the first friction block 53 and the second friction block 54 to rotate. Under the action of the spring 55, the second friction block 54 is always close to the first friction block 53. When the second friction block 54 rotates until the first magnetic block 56 is directly opposite the second magnetic block 57, the magnetic force between the first magnetic block 56 and the second magnetic block 57 is greater than the elastic force of the spring 55, causing the second friction block 54 to move away from the first friction block 53. This increases the distance between the first friction block 53 and the second friction block 54. Therefore, when receiving the push rod mechanism... 4. After the rod body is conveyed, the first friction block 53 and the second friction block 54 rotate synchronously. When the first magnetic block 56 is facing the second magnetic block 57, the distance between the first friction block 53 and the second friction block 54 increases, and the rod body can enter between the first friction block 53 and the second friction block 54. When the first magnetic block 56 and the second magnetic block 57 separate, the second friction block 54 is pressed against the first friction block 53 by the elastic force of the spring 55, thereby generating sufficient friction on the surface of the rod body, so that the rod body rotates with the first friction block 53 and the second friction block 54, thus changing the direction of the rod body.

[0036] Further, the feeding mechanism 6 includes: a feeding motor 61, a first pulley 62, a second pulley 63, and a friction belt 64; the feeding motor 61 is mounted on the frame 1; the first pulley 62 is fixed to the output end of the feeding motor 61; the second pulley 63 is rotatably mounted on the frame 1; the friction belt 64 is sleeved on the first pulley 62 and the second pulley 63; the feeding motor 61 is electrically connected to the controller 7. In practical applications, when the roller rotates under the action of the clamping and rotating mechanism 5 until it is in contact with the friction belt 64, the controller 7 controls the feeding motor 61 to start and drive the first pulley 62 to rotate. The second pulley 63 rotates accordingly under the action of the friction belt 64, and the roller moves downward with the friction belt 64 under the action of the friction belt 64, thereby outputting the roller.

[0037] Furthermore, a second sensor 12 for detecting the rotational position of the roller is also provided on the frame 1; the second sensor 12 is electrically connected to the controller 7. In this embodiment, the second sensor 12 is a laser sensor, but in other embodiments it can also be an infrared sensor, a proximity sensor, or other sensors capable of sensing the position of the roller; after the second sensor 12 senses the roller, the controller 7 controls the feeding motor 61 to start, which can effectively save energy.

[0038] Furthermore, a guide opening 13 is provided on the frame 1 to guide the rod to move vertically downwards; a chamfer is provided at the opening of the guide opening 13. In practical applications, when the rod is output downwards, it moves vertically downwards through the guide opening 13, thereby ensuring the accuracy of the rod output and facilitating the robotic arm below the guide opening 13 to grasp the rod and make cotton candy.

[0039] The present invention provides a roller feeding device for a cotton candy machine, which can improve the roller feeding efficiency.
