Description

Technical Field

[0001] This invention relates to the field of automated production technology of tarpaulin rolls, specifically to an automatic tarpaulin roll coating and forming device. Background Technology

[0002] As a traditional specialty snack in Changzhou, Jiangsu Province, caul fat rolls have a history of over a century. They are loved by the locals for their unique crispy exterior, soft interior, and sweet and mellow taste. The traditional production process of this snack is quite meticulous. First, fresh pork caul fat is selected and processed through multiple steps such as soaking, washing, and drying to give it good extensibility and toughness. Then, red bean paste filling is hand-rolled into evenly sized balls and tightly wrapped with the processed pork caul fat to form the initial dough. Egg whites are placed in a container and continuously beaten by hand to form a fluffy and delicate meringue. After the meringue is beaten to the appropriate state, the operator grabs an appropriate amount of meringue by hand and evenly wraps it on the surface of the red bean paste caul fat dough to form a complete spherical dough. Then, it is placed in a pot of oil at an appropriate temperature and fried until it turns golden brown.

[0003] In actual production, the quality of caul fat rolls is closely related to the skill level of the operators. Due to the high viscosity and fluidity of the whipped egg white paste, it easily sticks to the operator's fingers when hand-wrapping, requiring the operator to constantly clean the paste from their hands to ensure the caul fat rolls are aesthetically pleasing after shaping. In actual production, even a skilled operator can only produce a limited number of caul fat rolls per minute, resulting in extremely low production efficiency. This inefficient manual operation mode not only fails to meet the supply demands of restaurants during peak hours but also represents a fundamental obstacle to the industrialization and large-scale market promotion of this traditional specialty snack. Therefore, we propose an automatic batter-coating and shaping device for caul fat rolls. Summary of the Invention

[0010] Preferably, the spherical mold assembly has an arc-shaped support plate inside, and a semi-annular fitting groove is provided at the bottom of both the hemispherical mold A and the hemispherical mold B. When the hemispherical mold A and the hemispherical mold B are closed, the semi-annular fitting grooves combine to form a complete annular groove. The arc-shaped support plate is located in the annular groove, and an iron sleeve is fixedly installed on the lower surface of the arc-shaped support plate.

[0011] Preferably, a plurality of cylinders are fixedly installed on a frame below the material feeding chamber. Each cylinder corresponds to a spherical mold assembly.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention achieves fully automated production of garnish rolls from coating, battering, receiving, replenishing to frying through the setting of an oil tank, an oil-draining metal conveyor mechanism, a frame, a coating turntable, a mesh conveyor belt, a feeding chamber, a rotating shaft, a connecting frame, a spherical mold group, a hemispherical mold A, a hemispherical mold B, a connecting part, a support one, a support two, and an injection pipe.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-11 This invention provides a technical solution: an automatic coating and forming device for caulking rolls, comprising an oil tank 1, an oil-draining metal conveyor 2 installed inside the oil tank 1, the oil-draining metal conveyor 2 being used to convey the fried caulking rolls out of the oil tank 1 while draining excess oil, a frame 3 being provided on one side of the oil tank 1, a coating turntable 4 connected to a power unit being installed on the frame 3, the coating turntable 4 containing sufficient starch for coating the red bean paste blanks, a shovel plate being fixedly installed on the coating turntable 4, and a mesh conveyor belt 5 being fixedly installed on the frame 3, wherein the shovel plate is close to the feed end of the mesh conveyor belt 5, its function being to spread the starch-coated red bean paste blanks onto the feeder when the coating turntable 4 rotates. The dough is guided onto the mesh conveyor belt 5. One end of the mesh conveyor belt 5 extends into the coating turntable 4 to receive the red bean paste dough falling from the shovel. The other end of the mesh conveyor belt 5 is connected to the feeding chamber 6. The feeding chamber 6 is inclined and has a smooth inner wall, which allows the red bean paste dough to roll down to its discharge end by gravity. A feeding limiting mechanism is provided at the discharge end of the feeding chamber 6. This mechanism is used to control the timing of the falling of the red bean paste dough to ensure that only one red bean paste dough is released at a time to enter the next process. It should be noted that the feeding limiting mechanism can adopt the common direct-push feeding structure in the prior art. Since the feeding limiting mechanism is a common technical means used by those skilled in the art, this invention has not described it in detail.

[0033] A rotating shaft 7 is rotatably connected to the platform 3. The rotating shaft 7 is connected to a power source, such as a motor, and can rotate intermittently under the command of the control system. Since the power source, control system, and the power unit mentioned above are all technical means commonly used by those skilled in the art, this invention does not describe them in detail. The rotating shaft 7 has multiple slots 71 and multiple connecting frames 8 are provided on the rotating shaft 7. A rigid bracket 81 is fixedly installed on one side of the connecting frame 8. A slider 82 is fixedly installed on the rigid bracket 81, and the slider 82 can be limited within the slots 71. Sliding; and when the rotating shaft 7 rotates, it can drive the connecting frame 8 to rotate synchronously through the slot 71, the slider 82 and the rigid bracket 81. A support sleeve 13 is also fixedly installed on the platform 3. The rotating shaft 7 is located inside the support sleeve 13 and is rotatably connected to it. A limit groove 131 is opened on the support sleeve 13. When the rigid bracket 81 rotates with the rotating shaft 7 to a specific position, which means that the connecting frame 8 is located directly above the oil tank 1, the rigid bracket 81 will enter the limit groove 131 and descend along the limit groove 131 under the action of gravity.

[0034] Each connecting frame 8 has multiple spherical mold groups 9 below it. Each spherical mold group 9 has an opening at the top. Each spherical mold group 9 consists of a hemispherical mold A91 and a hemispherical mold B92. Both hemispherical mold A91 and hemispherical mold B92 are connected to the connecting frame 8 by a connecting part 93. Specifically, the connecting part 93 includes a driving block 94 disposed inside the connecting frame 8 and slidably connected to its inner wall. Both hemispherical mold A91 and hemispherical mold B92 are fixedly mounted with a fixed shaft 95. The fixed shaft 95 is connected to the bottom of the driving block 94 by a steel shaft 96. The steel shaft 96 is also slidably connected to the bottom inner wall of the connecting frame 8. When the driving block 94 moves inside the connecting frame 8, it can drive the hemispherical mold A91 or hemispherical mold B92 to move relative to the connecting frame 8 through the steel shaft 96 and the fixed shaft 95, thereby realizing the opening or closing of the mold.

[0035] To achieve precise control of hemispherical molds A91 and B92, a lead screw 83 rotatably connected to its inner wall is installed inside the connecting frame 8. A motor 84 is fixedly installed at one end of the connecting frame 8, and the output end of the motor 84 is fixedly connected to one end of the lead screw 83. A drive block 94 is installed on the lead screw 83 and threadedly engaged with it. The lead screw 83 includes a small-pitch region 85 and a large-pitch region 86, and the threads in these two regions rotate in opposite directions. The drive block 94 controlling hemispherical mold A91 is installed on the small-pitch region 85, and the drive block 94 controlling hemispherical mold B92 is installed on... In the large pitch area 86, when the motor 84 drives the lead screw 83 to rotate, the two drive blocks 94 will move in opposite directions, and the moving distance will vary depending on the pitch. The advantage of this design is that when the spherical mold group 9 is opened directly above the oil tank 1, the moving distance of the hemispherical mold B92 is greater than that of the hemispherical mold A91. As a result, during the opening of the spherical mold group 9, the solidified net oil roll will tilt and roll to one side, avoiding unstable falling posture or oil splashing caused by instantaneous detachment. This ensures the accuracy of the position and integrity of the net oil roll when it falls into the oil tank 1, which is beneficial to the uniformity of the subsequent frying process.

[0036] Each spherical mold assembly 9 is internally equipped with an arc-shaped support plate 97, which supports the bean paste blank when it enters the mold. The bottoms of hemispherical molds A91 and B92 are each provided with a semi-annular fitting groove 98. When the two hemispherical molds are closed, the two semi-annular fitting grooves 98 combine to form a complete annular groove, into which the arc-shaped support plate 97 is accommodated. An iron sleeve 99 is fixedly installed on the lower surface of the arc-shaped support plate 97. Below the feeding chamber 6, multiple cylinders 14 are fixedly installed on the platform 3. The number of cylinders 14 corresponds one-to-one with the number of spherical mold assemblies 9, and the cylinders 14 are located on the movement trajectory of the spherical mold assembly 9. A magnet 141 is fixedly installed at the output end of each cylinder 14. When the spherical mold assembly 9 rotates to the feeding chamber 6... When the material end is directly below, the iron sleeve 99 is exactly on the movement trajectory of the magnet part 141. The cylinder 14 can drive the magnet part 141 to rise and insert into the iron sleeve 99, thereby driving the arc-shaped support plate 97 to rise or fall. Multiple extrusion ports 90 are also provided on each semi-annular adapter groove 98. At the same time, multiple locking blocks 901 that are adapted to the shape of the extrusion ports 90 are installed on the lower surface of the arc-shaped support plate 97. The locking blocks 901 correspond one-to-one with the extrusion ports 90 on the semi-annular adapter groove 98 at the bottom of the hemispherical mold B92. When the arc-shaped support plate 97 descends to the lowest position, the locking blocks 901 will lock into the extrusion ports 90, thereby restricting the further movement of the arc-shaped support plate 97. If the cylinder 14 continues to descend at this time, the magnet part 141 will disengage from the iron sleeve 99, realizing the separation of the arc-shaped support plate 97 from the cylinder 14.

[0037] The oil tank 1 is also fixedly installed with bracket 10 and bracket 21, which are symmetrically arranged. Multiple injection tubes 12 are installed on both bracket 10 and bracket 21. The injection tubes 12 are located on the movement trajectory of the spherical mold group 9 and are used to inject egg white paste into the spherical mold group 9. In particular, the ends of the multiple injection tubes 12 on bracket 21 are fixedly installed with arc-shaped scrapers 121. During the injection process, the arc-shaped scrapers 121 are in contact with the top surface of the spherical mold group 9 to prevent the egg white paste from overflowing from the opening at the top of the mold, ensuring accurate injection volume and a smooth surface.

[0038] Each rigid support 81 has a ring magnet 87 fixedly installed on its lower surface, and an electromagnet 15 is fixedly installed on the platform 3. When the spherical mold assembly 9 is directly above the oil pool 1, the ring magnet 87 is exactly directly above the electromagnet 15. When the electromagnet 15 is energized, it can generate a repulsive force on the ring magnet 87. In addition, a guide shaft 16 is fixedly installed on the platform 3. A spring part 17 is sleeved on the guide shaft 16. Each rigid support 81 has a through hole. When the rigid support 81 descends along the limiting groove 131, the through hole will fit into the guide shaft 16 and compress the spring part 17. The spring part 17 can slow down the descent speed of the rigid support 81, so that the spherical mold assembly 9 enters the oil pool 1 smoothly and avoids the egg white batter from splashing out due to excessive speed.

[0039] Furthermore, multiple pusher frames 21 are fixedly installed on the oil-draining metal conveyor mechanism 2. When the pusher frames 21 move with the conveyor mechanism, they can push the fried garnet rolls in the oil tank 1 forward. Multiple inclined frames 18 are also fixedly installed on the inner wall of the oil tank 1. When the garnet rolls pass through the inclined frames 18, the inclined frames 18 will exert a force on the garnet rolls, causing them to roll in the oil, ensuring that the spherical surface is heated evenly and the frying effect is better.

[0040] It should be noted that, in order to ensure that the egg white batter does not stick in the spherical mold assembly 9, the inner walls of all spherical mold assemblies 9 and the surface of the arc-shaped support plate 97 are coated with a food-grade non-stick coating, such as a polytetrafluoroethylene coating. In daily maintenance, operators need to clean the spherical mold assembly 9 and the arc-shaped support plate 97 regularly to remove residual batter and ensure the smooth progress of subsequent production.

[0041] Specifically, firstly, the red bean paste dough wrapped in pig caul fat is placed in the starch-coating turntable 4. The turntable 4 rotates continuously, evenly coating the surface of the red bean paste with a layer of starch. This starch coating allows a gelatinized layer to quickly form when the red bean paste comes into contact with the moist egg white batter. This gelatinized layer enhances the adhesion of the red bean paste to the egg white batter, preventing it from slipping. When the red bean paste rotates to the spatula, the spatula guides it onto the mesh conveyor belt 5. The mesh conveyor belt 5 transports the red bean paste to the unloading chamber 6, where it rolls along the inclined inner wall. As the material falls to the discharge end, the feeding limiting mechanism releases a red bean paste blank at regular intervals, causing it to fall. At the same time, the rotating shaft 7 rotates intermittently under the drive of the power source, driving the rigid support 81 and the connecting frame 8 to rotate. For ease of understanding, let's take the example of four connecting frames 8 on the rotating shaft 7: Assume that the first connecting frame 8 is located at the corresponding position of the support 10, the second connecting frame 8 is located at the corresponding position of the feeding chamber 6, the third connecting frame 8 is located at the corresponding position of the support 11, and the fourth connecting frame 8 is located directly above the oil tank 1.

[0042] When the spherical mold assembly 9 on the first connecting frame 8 is located directly below the support 10, the injection pipe 12 on the support 10 is located directly above the spherical mold assembly 9. Since the top of the spherical mold assembly 9 has an opening, the injection pipe 12 can inject the egg white batter into the spherical mold assembly 9 through the opening. During injection, most of the space inside the spherical mold assembly 9 is filled with egg white batter, leaving only a small amount of space at the top unfilled. The purpose of this is to ensure that when the red bean paste enters the spherical mold assembly 9 later, the egg white batter will not overflow due to the entry of the red bean paste, thus avoiding waste and contamination.

[0043] After the injection is completed, the rotating shaft 7 rotates, and the spherical mold assembly 9 on the first connecting frame 8 moves away from the support 10 position. The spherical mold assembly 9 on the second connecting frame 8 rotates to the support 10 position, and the above injection process is repeated. At the same time, the spherical mold assembly 9 on the first connecting frame 8 rotates to directly below the discharge end of the discharge chamber 6. When the spherical mold assembly 9 is directly below the discharge end of the discharge chamber 6, the cylinder 14 is activated, and the magnet part 141 on the output end of the cylinder 14 moves upward. The magnet part 141 enters the arc-shaped support plate. Inside the iron sleeve 99 at the bottom of 97, and driven by the cylinder 14, the arc-shaped support plate 97 is raised to the top position. At this time, the feeding limiting mechanism releases a red bean paste blank. The red bean paste falls from the discharge end of the feeding chamber 6 and lands on the arc-shaped support plate 97. Then, the cylinder 14 controls the arc-shaped support plate 97 to slowly descend, so that the red bean paste gradually enters the egg white paste in the spherical mold group 9. Since the surface of the red bean paste is coated with starch, it quickly forms a gelatinized layer after encountering the egg white paste, which enhances the adhesion. The red bean paste is stably supported inside the egg white paste and will not sink or shift.

[0044] The arc-shaped support plate 97 continues to descend under the action of the cylinder 14 until the locking block 901 at the bottom of the arc-shaped support plate 97 enters the extrusion port 90 on the semi-annular adapter groove 98. After the locking block 901 engages with the extrusion port 90, the output end of the cylinder 14 continues to descend. At this point, since the arc-shaped support plate 97 is limited by the annular groove, it cannot descend further. The magnet part 141 disengages from the iron sleeve 99, realizing the separation of the arc-shaped support plate 97 from the cylinder 14. Then the rotating shaft 7 rotates again, and the spherical mold assembly... 9. Move away from the material unloading chamber 6 and rotate to directly below the support 2 11. At this time, the spherical mold assembly 9 is located directly below the injection pipe 12 on the support 2 11, and the arc-shaped scraper 121 at the end of the injection pipe 12 of the support 2 11 is in contact with the top surface of the spherical mold assembly 9. The injection pipe 12 injects egg white batter again, filling the remaining space inside the spherical mold assembly 9. The function of the arc-shaped scraper 121 is to prevent the egg white batter from flowing out from the opening at the top of the spherical mold assembly 9, ensuring that the filling is full and the surface is flat.

[0045] After the filling is completed, the rotating shaft 7 continues to rotate, and the spherical mold assembly 9 rotates to directly above the oil tank 1. At this time, the rigid support 81 is exactly inside the limiting groove 131 of the support sleeve 13. Under the action of gravity, the rigid support 81 drives the connecting frame 8 and all its components to slide down along the limiting groove 131 and make a descent movement. When it is close to the end, the through hole on the rigid support 81 is inserted from the top of the guide shaft 16 and squeezes the spring part 17 sleeved on the guide shaft 16. Of course, during the descent of the rigid support 81, the electromagnet 15 can be energized appropriately to reduce the descent speed of the rigid support 81 and make it gently contact the spring part 17. The spring part 17 and the guide shaft 16 need to be made of demagnetizing material. Under the buffering effect of the spring part 17, the descent speed of the rigid support 81, the connecting frame 8 and the spherical mold assembly 9 is slowed down, so that the spherical mold assembly 9 can enter the oil tank 1 smoothly.

[0046] After the spherical mold assembly 9 is immersed in the hot oil in the oil tank 1, the high-temperature oil transfers heat through the wall of the spherical mold assembly 9, instantly heating the egg white paste inside the spherical mold assembly 9. The surface of the egg white paste quickly solidifies, forming a solidified shell. After a few seconds, once the egg white paste shell is completely solidified, the motor 84 starts rotating forward. The output end of the motor 84 drives the lead screw 83 to rotate. Since the lead screw 83 includes a small pitch region 85 and a large pitch region 86, and the threads of the two regions rotate in opposite directions, the drive block 94 installed on the small pitch region 85 moves in the opposite direction to the drive block 94 installed on the large pitch region 86. The hemispherical molds A91 and B92 move in opposite directions, the spherical mold assembly 9 opens, and the solidified egg white paste shell inside, which encloses the red bean paste, detaches from the spherical mold assembly 9 and falls into the oil tank 1.

[0047] After the spherical mold assembly 9 is opened, the egg white batter shell falls into the oil pool 1. At this time, the electromagnet 15 is energized. After the electromagnet 15 is energized, it generates a repulsive force on the ring magnet 87 on the lower surface of the rigid support 81, pushing the rigid support 81 to move upward. The rigid support 81 drives the connecting frame 8 and its upper components to rise along the limiting groove 131 until it returns to the top of the limiting groove 131. Then the rotating shaft 7 continues to rotate, and the rigid support 81 leaves the limiting groove 131. The next rigid support 81 moves to the limiting groove 131, repeating the above process of falling, entering oil, opening the mold, and rising. The rigid support 81 that leaves the limiting groove 131 continues to rotate with the rotating shaft 7. When it returns to the corresponding position of the support 10, the motor 84 reverses and drives the lead screw 83 to rotate in the opposite direction, so that the hemispherical mold A91 and hemispherical mold B92 close again, forming a complete spherical mold assembly 9, ready for the next round of work cycle.

[0048] The egg white batter shell falling into the oil tank 1 is rapidly fried under the action of the high-temperature oil, forming a complete caulking roll, which floats on the surface of the oil. The oil-draining metal conveyor 2 operates continuously, and multiple pusher frames 21 installed on it push the caulking roll forward in the oil tank 1. During the movement, the caulking roll passes through multiple inclined frames 18 fixedly installed on the inner wall of the oil tank 1. The inclined frames 18 exert a force on the passing caulking roll, causing the spherical caulking roll to roll in the oil, thereby ensuring that all sides of its spherical shape can be evenly contacted with the high-temperature oil, resulting in a uniform frying effect. Finally, the fried caulking roll is conveyed out of the oil tank 1 by the oil-draining metal conveyor 2, completing the entire automatic battering and forming process. Through the structural design of this invention, the automated and continuous production of caulking rolls is realized, effectively solving the problems of low efficiency and unstable quality in traditional manual production.
