Automatic feeding device for pearl powder ball production

Abstract

This utility model relates to the technical field of tapioca pearl production equipment, specifically disclosing an automatic feeding device for tapioca pearl production. The device includes a frame with guide grooves on both inner walls. Springs are connected inside the guide grooves. Under the action of a first spiral blade, the tapioca pearl slowly falls into the inner storage cylinder. A discharge plate inside the inner storage cylinder guides the pearl towards the bottom, extending its falling speed. As the inner storage cylinder rotates, the pearl falls onto a second spiral blade inside, further extending its falling speed. When the first and second discharge holes align, the pearl inside the inner storage cylinder enters the outer storage cylinder and slides downwards into the feeding device. This avoids blockages or damage caused by a large number of rapid falls, ensuring the continuity and stability of the feeding process, thus significantly improving production efficiency and bringing significant benefits to the tapioca pearl feeding process.

Description

Technical Field

[0001] This utility model relates to the technical field of tapioca pearl production equipment, and in particular to an automatic feeding device for tapioca pearl production. Background Technology

[0002] Taro balls with pearls are a dessert with a unique texture and flavor. They cleverly combine the bouncy and smooth texture of tapioca pearls with the soft and sweet taste of taro balls, providing diners with a rich and unforgettable taste experience. In the production process, the pearls are usually made by mixing tapioca starch, water, and caramel coloring to form small black pearl-like particles, while the taro balls are made by combining taro, sweet potato, purple sweet potato and other ingredients with tapioca flour. They are attractive in color and have a delicate texture. After being formed, taro balls with pearls need to go through a series of delicate processing steps. Among them, the feeding and filling device plays a crucial role. This device is designed to efficiently and accurately transport the taro balls with pearls from the production line to the packaging container.

[0003] For example, Chinese patent CN216581132U discloses an automatic pearl tapioca filling machine, including a frame, a storage tank, a controller, a weighing platform, a support platform, a weighing component, a discharge pipe, a V-shaped weighing trough, a first switch control valve, a Z-shaped feeding pipe, and a feeding component. The first switch control valve is positioned directly above the top of the discharge pipe, and the outlet end of the Z-shaped feeding pipe is positioned directly above the V-shaped weighing trough. The pearl tapioca balls in the storage tank are fed into the V-shaped weighing trough on the weighing platform through the feeding component and the Z-shaped feeding pipe. The pearl tapioca balls in the V-shaped weighing trough are weighed by the weighing component. At this time, the packaging bag is opened so that the bag opening is aligned with the bottom of the discharge pipe. After weighing is completed, the controller controls the first switch control valve to open, and the weighed pearl tapioca balls can fall into the packaging bag through the discharge pipe.

[0004] The aforementioned patent addresses the problem that most tapioca pearl filling processes rely on manual weighing and filling, resulting in low filling efficiency and inconsistent weights in each bag. However, the feeding and filling machine still has some shortcomings that need improvement. The tapioca pearl particles enter the storage cylinder through the inlet, and then enter the feeding tube. However, in this crucial transfer process, due to the lack of a necessary guiding and delaying mechanism, a large number of tapioca pearl particles fall almost simultaneously under gravity. This causes occasional slight congestion at the inlet of the feeding tube, resulting in insufficient feeding smoothness, affecting the fluency and continuity of feeding, and also impacting overall production efficiency.

Arc-shaped push blocks are fixedly connected to both sides of the top of the fixed ring. One side of the cam plate abuts against one side of the arc-shaped push block.

[0009] Furthermore, the locking assembly includes a cylinder, which is fixedly connected to both sides inside the frame. The output end of the cylinder is connected to a support block via a coupling.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0013] Firstly, in this practical application, by connecting a mounting frame to the outer storage cylinder, the inner storage cylinder rotates inside the outer storage cylinder. A first discharge hole is opened inside the outer storage cylinder, and a second discharge hole is opened at the bottom of the inner storage cylinder. The taro balls first enter the second feed pipe through the first feed pipe, and slowly fall into the inner storage cylinder under the action of the first spiral blade inside the second feed pipe. They are guided to move towards the bottom of the inner storage cylinder by the discharge plate inside the inner storage cylinder, extending the falling speed of the taro balls. As the inner storage cylinder rotates, the taro balls will fall onto the second spiral blade inside the inner storage cylinder, further extending the falling speed of the taro balls. When the first discharge hole and the second discharge hole are aligned, the taro balls inside the inner storage cylinder enter the inner storage cylinder and slide down into the feeding device. This avoids the problem of blockage or damage caused by a large number of rapid falls, ensuring the continuity and stability of the feeding process, thereby significantly improving production efficiency and bringing significant benefits to the feeding process of taro balls.

[0014] Secondly, in this application, during the feeding process of taro balls, the first motor drives the cam plate to rotate. The cam plate intermittently contacts the arc-shaped push block, which drives the fixed ring to move. The fixed ring is connected to the outer cylinder of the storage tank. At the same time, the guide blocks connected to both sides of the fixed ring slide in the guide groove in the frame to push the spring to deform. The spring is stably deformed under the action of the correction component. The movement path of the outer cylinder of the storage tank is deviated, which causes the outer cylinder of the storage tank to vibrate. This causes the first pair of connecting pipes to slide in the second pair of connecting pipes, which can further prevent the connection between the outer cylinder of the storage tank and the feeding device from becoming blocked. This allows the taro balls to enter the feeding device smoothly and stably, thereby improving the efficiency of the entire feeding process.

[0015] Thirdly, in this application, by installing a transmission assembly on the mounting frame, the second motor drives the first shaft to rotate, causing the two worm gears on the first shaft to rotate simultaneously, thereby driving the two worm wheels to rotate, which in turn drive the second shaft to rotate. Since both the first and second helical blades are connected to the second shaft, not only can the first helical blade rotate, but the second helical blade can also be driven to rotate the inner cylinder of the storage cylinder. This brings many benefits, such as efficient synchronous drive, enhanced conveying capacity, optimized space utilization, improved equipment reliability, and cost savings.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-8In this embodiment, an automatic feeding device for pearl tapioca pearl production includes a frame 1. Guide grooves 2 are formed on both inner walls of the frame 1. A spring 3 is connected inside the guide groove 2, and a guide block 5 is fixedly connected to the top of the spring 3. The guide block 5 is slidably connected inside the guide groove 2. A correction component 6 is provided inside the guide groove 2. A fixing ring 4 is fixedly connected to the side of the guide block 5 away from the frame 1. Pushing components 7 are provided on both sides of the frame 1. The spring 3 vibrates within the guide groove 2 through the pushing components 7. A storage outer cylinder 9 is integrally formed and connected to the inner side of the fixing ring 4. A storage container is rotatably connected inside the storage outer cylinder 9. The inner cylinder 11 has first discharge holes 91 on both sides of the inner cylinder 9, and second discharge holes 111 on both sides of the bottom end of the inner cylinder 11, with the second discharge holes 111 matching each other. A mounting bracket 10 is fixedly connected to the top of the outer cylinder 9. A first feed pipe 12 is fixedly connected to one side of the top of the mounting bracket 10, and a second feed pipe 13 is fixedly connected to one side of the first feed pipe 12. A flange is installed on the second feed pipe 13 and connected to a flexible hose. A first spiral blade 14 is rotatably connected inside the first feed pipe 12, and a second spiral blade 15 is fixedly connected inside the inner cylinder 11. A material drop plate 16 is fixedly connected above the second spiral blade 15. A transmission assembly 17 for driving the first spiral blade 14 and the inner storage cylinder 11 to rotate is provided on one side of the mounting frame 10. A first pair of connecting pipes 92 is fixedly connected to the bottom end of the outer storage cylinder 9. A feeding device 18 is provided on the frame 1 below the outer storage cylinder 9. The feeding device 18 includes a motor, spiral conveying blades, etc., and can transport the taro balls to the next processing unit. Specifically, it is a structure disclosed in the prior art and will not be repeated here. A second pair of connecting pipes 181 is fixedly connected to one side of the feeding device 18. The first pair of connecting pipes 92 is slidably inserted into the second pair of connecting pipes 181. The frame... Locking components 8 are located on both sides of the push component 7 below the push component 1. By adding a guiding delay mechanism, the falling speed and quantity of taro ball particles can be effectively controlled, avoiding a large number of particles from flooding into the feeding pipe at the same time. This can effectively prevent clogging caused by mutual squeezing or prolonged standing during the conveying process of taro balls, thereby significantly reducing congestion at the feed inlet and making the feeding process smoother and more stable. Reducing congestion means reducing downtime for cleaning due to blockage, enabling the production line to operate continuously and efficiently, thereby increasing output and reducing production costs. This improves the automation and intelligence level of the entire production line, making the production process more efficient and reliable.

[0027] Please see Figure 5The correction component 6 includes a limiting groove 61, which is formed on both sides inside the guide groove 2. A limiting block 62 is slidably connected inside the limiting groove 61. One end of the limiting block 62 is fixedly connected to one end of the guide block 5. A guide rod 63 is fixedly connected inside the guide groove 2. A guide hole 64 is formed inside the guide block 5. The guide rod 63 is slidably connected to the guide hole 64. The spring 3 is sleeved on the outside of the guide rod 63.

[0028] Please see Figure 3 The pushing assembly 7 includes a first mounting plate 71, which is fixedly connected to the outside of the frame 1. A second mounting plate 72 is fixedly connected to the inside of the frame 1. A first motor 73 is fixedly connected to the side of the first mounting plate 71 near the second mounting plate 72. The output end of the first motor 73 is connected to a cam plate 74 via a coupling. The cam plate 74 is located above the fixed ring 4 and is movably connected to the fixed ring 4. Arc-shaped push blocks 75 are fixedly connected to both sides of the top of the fixed ring 4. One side of the cam plate 74 abuts against one side of the arc-shaped push block 75. By setting the pushing assembly 7, the frame... A first assembly plate 71 and a second assembly plate 72 are installed on the first assembly plate 71. A first motor 73 is fixed on the first assembly plate 71, and the output shaft of the first motor 73 rotates on the second assembly plate 72. The first motor 73 drives the cam plate 74 to rotate, which in turn drives the arc-shaped push block 75. The arc-shaped push block 75 pushes the fixed ring 4, causing the outer storage cylinder 9 to move under force. At this time, the guide block 5 connected to the fixed ring 4 slides in the guide groove 2, pushing the spring 3 to deform. As the cam plate 74 intermittently contacts the arc-shaped push block 75, the outer storage cylinder 9 vibrates, which can effectively prevent the taro balls from clogging in the feeding system and facilitate the feeding operation.

[0029] Please see Figure 2-3 The locking assembly 8 includes a cylinder 81, which is fixedly connected to both sides of the inside of the frame 1. The output end of the cylinder 81 is connected to a support block 82 via a coupling. The bottom end of the fixed ring 4 has fitting grooves 83 on both sides. The support block 82 matches the fitting grooves 83 and the two are movably connected. The frame 1 has a concealed groove 84 below the fixed ring 4. The support block 82 matches the concealed groove 84 and the two are movably connected. By setting the locking assembly 8, when the feeding equipment is not working, the cylinder 81 drives the support block 82 to move into the fitting groove 83 at the bottom of the fixed ring 4 to support the outer cylinder 9 and make it more stable. When the feeding equipment is working, the cylinder 81 drives the support block 82 to be stored in the fitting groove 83, which does not occupy space and makes the whole more beautiful and simple.

[0030] Please see Figure 7-8The transmission assembly 17 includes an assembly frame 176, which is fixedly connected to the top of the mounting frame 10 near the first feed pipe 12. A second motor 171 is fixedly connected to one side of the assembly frame 176. The output end of the second motor 171 is connected to a first shaft 172 via a coupling. The first shaft 172 is rotatably connected inside the assembly frame 176. A worm gear 173 is fixedly connected to the outer surface of the first shaft 172. A worm wheel 174 is meshed with one side of the worm gear 173. A second shaft 175 is fixedly connected to the middle of the worm wheel 174. The second shaft 175 is fixedly connected to the first helical blade 14, and another second shaft 175 is fixedly connected to the second helical blade 15. By setting the transmission assembly 17, the mounting frame 176 is fixed on the mounting frame 10. The second motor 171 on the mounting frame 176 drives the first shaft 172 to rotate. The first shaft 172 drives the worm gear 173 to rotate. The worm gear 173 drives the worm wheel 174 to rotate. Thus, the worm wheel 174 drives the second shaft 175 to rotate, causing the first helical blade 14 to rotate, and causing the second helical blade 15 to drive the outer storage cylinder 9 to rotate, providing driving force for the operation of both.

[0031] Please see Figure 1 A support platform 21 is fixedly connected to the frame 1 below the feeding device 18. A weighing sensor 20 is provided at the top of the support platform 21, and a weighing platform 19 is connected to the top of the weighing sensor 20. A control valve 22 is provided at the bottom of the weighing platform 19, and a discharge pipe 23 is fixedly connected to the bottom of the support platform 21. The discharge pipe 23 is located directly below the control valve 22. By setting up the support platform 21 and installing the weighing platform 19 on top of the support platform 21, the taro balls are conveyed to the weighing platform 19 by the feeding device 18. They are weighed under the action of the weighing sensor 20 under the weighing platform 19. The control valve 22 under the weighing platform 19 can be used to make the taro balls inside the weighing platform 19 fall downward and be discharged through the discharge pipe 23 below.

[0032] The working principle of this utility model is as follows: The taro balls first enter the second feed pipe 13 through the first feed pipe 12. The second motor 171 drives the first shaft 172 to rotate, causing the two worm gears 173 on the first shaft 172 to rotate simultaneously. This, in turn, drives the two worm wheels 174 to rotate, which in turn drives the second shaft 175 to rotate. One second shaft 175 drives the first spiral blade 14 to rotate, and the other second shaft 175, through the first spiral blade 14, drives the inner storage cylinder 11 to rotate inside the outer storage cylinder 9. At this time, the taro balls enter the second feed pipe 13. The taro balls, fed into the second feed pipe 13, slowly fall into the inner storage cylinder 11 under the action of the first spiral blade 14. Guided by the discharge plate 16 inside the inner storage cylinder 11, they move towards the bottom of the cylinder, extending their falling speed. As the inner storage cylinder 11 rotates, the taro balls fall onto the second spiral blade 15 inside, further extending their falling speed. As the inner storage cylinder 11 rotates within the outer storage cylinder 9, when the first discharge hole 91 aligns with the second discharge hole 111, at this point... The taro balls inside the inner storage cylinder 11 slide down into the outer storage cylinder 9 and into the feeding device 18, avoiding blockages or damage caused by a large number of rapid falls. This ensures the continuity and stability of the feeding process, thereby significantly improving production efficiency. During the feeding process, the first motor 73 drives the cam plate 74 to rotate. The cam plate 74 intermittently contacts the arc-shaped push block 75, which in turn drives the fixed ring 4 to move. The fixed ring 4 is connected to the outer storage cylinder 9, and the two sides of the fixed ring 4... The guide block 5 slides in the guide groove 2 inside the frame 1 to push the spring 3 to deform. The limit block 62 slides in the limit groove 61, and the guide rod 63 slides in the guide hole 64 to prevent the movement path of the storage cylinder 9 from deviating. This causes the storage cylinder 9 to vibrate, and the first pair of connecting pipes 92 slides in the second pair of connecting pipes 181. This further prevents blockage at the connection between the storage cylinder 9 and the feeding device 18, allowing the taro balls to enter the feeding device 18 smoothly and stably, thereby improving the efficiency of the entire feeding process.
