Description

Technical Field

[0001] This invention relates to the field of spring roll production technology, specifically to a spring roll mechanical wrapper forming device. Background Technology

[0002] Spring rolls, also known as spring pancakes, spring platters, or thin pancakes, are made through a series of steps including making the spring roll wrappers, preparing the filling, filling the wrappers, folding the wrappers, rolling, and packaging. The filling process involves injecting the filling into the spring roll wrapper. After filling, the spring roll is moved to the folding process, where the left and right sides of the wrapper are folded to enclose the filling, allowing it to be rolled into shape.

[0003] Existing spring roll production equipment typically uses a spiral propulsion method for filling, requiring the filling to be transported through pipes. However, filling adhering to the pipes is difficult to clean, posing a hygiene and safety hazard. Folding the spring roll wrappers is achieved using air blowing, but this method requires spring roll wrappers with low hardness and thinness, demanding high precision. The folding effect is unsatisfactory, with uncertainties in the shaping process, making successful folding impossible to guarantee. Furthermore, it requires high-quality clean air, consumes a large amount of compressed air, resulting in significant costs, and insufficient compressed air cleanliness poses a major food safety risk. Before the rolling process, a paste needs to be applied to the spring roll wrappers to... To prevent spring rolls from opening and becoming loose when rolled into a round shape, the current common practice is to apply a paste to the spring roll wrapper using a nozzle, and then use high-pressure air to atomize and spray the paste to cover the wrapper. However, this method has the disadvantage of covering too large an area with paste, resulting in paste waste. Furthermore, chevron and beveled wire mesh are typically used to roll the spring rolls into a round shape. After folding, the spring rolls pass under the chevron and beveled wire mesh via a conveyor belt, relying on the friction between the spring rolls and the mesh to form the roll. However, due to the angle at which the spring rolls enter and the weight of the mesh belts, the success rate is greatly affected, and spring rolls rolled using chevron and beveled wire mesh are not firm enough. Summary of the Invention

[0004] This invention addresses the problems of existing spring roll production equipment, such as the difficulty in cleaning the filling conveying pipes, unsatisfactory spring roll folding results, large slurry coverage during spring roll coating, and insufficient firmness of the rolled spring rolls. It provides a mechanical spring roll folding and forming device that integrates spring roll filling, spring roll folding, spring roll coating, and spring roll rolling mechanisms into one unit. Filling is no longer achieved through pipes, making cleaning easier. The mechanical folding process allows for control of the spring roll's posture and folding process, ensuring proper folding. It effectively reduces the slurry coating area on the spring roll, minimizing waste. Furthermore, it can roll spring rolls of different sizes while ensuring a firmer finished product.

The transmission component drives the folding component to move laterally left and right, ensuring that the folding component and the rear conveyor belt have the same speed, so as to ensure that the folding component completes the folding of the spring roll wrappers.

[0016] Furthermore, the folding assembly includes a moving plate, a flipping cylinder, a connecting rod structure, and a mold plate. The moving plate is connected to a transmission assembly, and the piston rod of the flipping cylinder is connected to the connecting rod structure. The connecting rod structure is connected to a flipping seat, which is fixedly mounted at the bottom of the mold plate. The mold plate is rotatably mounted at the upper end of the moving plate.

A dispensing core is fitted inside the dispensing head; the upper end of the dispensing core extends into the spring seat, and the lower end of the dispensing core passes through the dispensing hole and extends to the outside of the dispensing head. The end of the dispensing core can block the dispensing hole. When the dispensing core is lifted under force, the dispensing material can flow through the gap between the dispensing core and the dispensing head onto the spring roll wrapper, thereby effectively reducing the dispensing area on the spring roll and minimizing material waste.

[0021] Furthermore, the rolling mechanism includes two fixed side plates, an upper support plate, and rolling rods. The two fixed side plates are spaced apart at the bottom of the upper support plate, and multiple rolling rods are movably arranged between the two fixed side plates.

[0022] The beneficial effects of the present invention through the above technical solution are as follows: 1. This invention integrates spring roll filling, spring roll folding, spring roll skin coating, and spring roll rolling mechanism into one unit. Spring roll filling does not require piped delivery of filling, making cleaning convenient. Spring roll folding is completed by a mechanical structure, which can control the posture and folding process of the spring roll skin, ensuring the spring roll skin is formed. It can effectively reduce the area of ​​coating the spring roll skin, reducing coating waste. At the same time, it can roll spring rolls of different sizes and ensure that the rolled spring rolls are more compact.

[0023] 2. The filling mechanism of this invention does not require the delivery of filling through pipelines, making cleaning convenient; it uses a spiral working method to propel the filling, while the V-shaped shaft continuously stirs the filling, keeping it in a flowing state; and the stroke of the pushing cylinder makes it easy to control the size and weight of the filling, expanding the range of applicable fillings, and it can be used for both viscous and loose fillings; at the same time, the filling size can be controlled by changing the filling mold.

[0024] 3. The first folding mechanism of the present invention drives the rotating shaft to rotate through a rotating cylinder, so that the gripper assembly rotates quickly to complete the first folding of the spring roll, so that the spring roll skin is folded in half and in close contact with the filling.

[0025] 4. The crease mechanism of this invention completes the crease operation on the spring roll wrapper through two crease rollers, so as to facilitate the subsequent second folding operation.

[0026] 5. The second folding mechanism of this invention achieves the folding of the spring roll wrapper on both sides through two flipping folding mechanisms. The folding of the spring roll is completed through a mechanical structure, which can effectively control the folding posture and folding process of the spring roll wrapper, improve the folding effect of the spring roll, ensure the spring roll is formed, and thus improve the success rate of spring roll folding; wherein the position adjustment component is used to adjust the position of the transmission component and the folding component, thereby ensuring the folding effect of the spring roll and realizing the production of spring rolls of different sizes.

[0027] 6. The lifting cylinder of the guide bar mechanism of the present invention drives the lifting plate to descend, so that the lifting plate drives the guide bar to descend, so that when the spring roll is conveyed on the rear conveyor belt for the second folding operation, the guide bar prevents the spring roll skin from being over-folded or folded off-center.

[0028] 7. The present invention uses a centering mechanism to center the spring rolls after the folding process is completed, so as to facilitate the subsequent application of sizing.

[0029] 8. The present invention completes the sizing operation of spring rolls through a sizing mechanism, which can effectively reduce the sizing area of ​​the spring roll skin and reduce sizing waste; wherein when the sizing cylinder drives the sizing head to descend and the sizing core is lifted by force, the sizing can flow onto the spring roll skin through the gap between the sizing core and the sizing head.

[0030] 9. The spring roll rolling mechanism of the present invention can make slight adjustments to the spring roll entry angle through the lifting components on the two gantry frames, which can roll spring rolls of different sizes and ensure that the rolled spring rolls are more compact, thereby improving the success rate of spring roll rolling. The spring roll is rolled by the friction between the spring roll and the conveyor belt, the blocking force of the rolling rod, the downward pressure of the rolling rod on the spring roll, and the compaction effect of the previous rolling rod.

[0055] A sensor plate 608 is also provided on one side of the motion plate 6061, and two sensors 607 are spaced apart on the motion frame 603. In this embodiment, the movement of the folding leather assembly is controlled by the cooperation of the sensor plate 608 and the sensor 607. When the sensor plate 608 moves above the sensor 607, the sensor 607 transmits a signal to the control box 10, which then controls the forward and reverse rotation of the servo motor 6041, thereby realizing the movement of the folding leather assembly 606 in different directions. The servo motor 6041 can also control the speed of the folding leather assembly, ensuring that the speed of the folding leather assembly 606 is the same as that of the rear conveyor belt 16.

The lower end of the spring seat 803 is connected to the pulp dispensing head 805. A connecting sleeve is installed at the joint of the spring seat 803 and the pulp dispensing head 805. The connecting sleeve is of a "convex"-shaped structure, and is located inside the spring seat 803 and the pulp dispensing head 805. The upper end of the connecting sleeve is in threaded connection with the spring seat 803, and the lower end thereof is in interference fit with the pulp dispensing head 805. The U-shaped frame 801 is mounted on the top of the conveying side plate of the rolling conveying assembly 17.

[0058] A pulp dispensing hole is opened at the bottom of the pulp dispensing head 805, and the pulp dispensing hole is of a truncated cone-shaped structure. The pulp dispensing head 805 is communicated with a pulp delivery pipe 8051 arranged to tilt upward. A pulp dispensing core 806 is sleeved inside the pulp dispensing head 805.

In this embodiment, the spring 804 is used to generate a acting force on the pulp dispensing core 806, so that the lower end of the pulp dispensing core 806 blocks the pulp dispensing hole; when the pulp dispensing cylinder 802 drives the spring seat 803 and the pulp dispensing head 805 to descend, the end of the lower end of the pulp dispensing core 806 presses against the spring roll pulp dispensing position, after the pulp dispensing core 806 is forced to lift, the pulp can flow to the spring roll wrapper through the gap between the pulp dispensing core 806 and the pulp dispensing head 805. After the pulp dispensing is completed, the pulp dispensing cylinder 802 drives the spring seat 803 and the pulp dispensing head 805 to ascend, and the pulp dispensing core 806 returns to the initial position to re-block the pulp dispensing hole under the acting force of the spring 804.

[0059] The winding mechanism 9 includes two fixed side plates 906, an upper support plate 901, and winding rods 908. The two fixed side plates 906 are spaced apart at the bottom of the upper support plate 901, and multiple winding rods 908 are movably arranged between the two fixed side plates 906. Multiple strip holes 907 are spaced apart on the fixed side plates 906, and the ends of the winding rods 908 are fitted into the strip holes 907. The height of the strip holes 907 at the front end of the fixed side plates 906 gradually decreases from left to right, and the multiple winding rods 908 at the front end of the two fixed side plates 906 form an inclined plane. The winding mechanism 9 also includes two gantry frames 902, each of which is equipped with a lifting component for adjusting the height of the upper support plate 901. The gantry frames 902 are installed on the top of the conveying side plate of the winding conveying assembly 17. In this embodiment, the spring rolls that have completed the sizing process continue to be conveyed forward on the conveyor belt of the rolling and conveying assembly 17 to the rolling mechanism 9. The spring rolls pass through the rolling rod 908 at the front end of the fixed side plate 906 and undergo a pre-rolling action, which has a rolling and pushing effect on the spring rolls and makes it easier for the spring rolls to enter. Driven by the conveyor belt, the spring rolls are rolled through the friction between the spring rolls and the conveyor belt, the blocking force of the rolling rod 908, the downward pressure of the rolling rod 908 on the spring rolls, and the compaction effect of the previous rolling rod 908 during its descent. This process is repeated multiple times to make the rolled spring rolls more compact. During the process of the spring rolls being driven forward by the conveyor belt, the rolling rod 908 moves up and down under the guidance of the strip hole 907 after being hit by the spring rolls, which has the function of blocking and compacting the spring rolls.

[0060] One of the gantry frames 902 has one lifting assembly, and the other gantry frame 902 has two lifting assemblies. The lifting assembly includes a rhomboid bearing 903 and a lifting screw 904. The rhomboid bearing 903 is installed on the top of the gantry frame 902. The lifting screw 904 is interference-fitted with the inner ring of the rhomboid bearing 903. A fixing nut 905 is provided on the lifting screw 904. The fixing nut 905 is fixedly installed on the top of the upper support plate 901. The lower end of the lifting screw 904 passes through the upper support plate 901 and is slidably connected to the upper support plate 901. The upper support plate 901 has a through hole corresponding to the lifting screw 904. The fixing nut 905 is welded and fixed at the through hole. In this embodiment, the height of the rolling rod 908 can be adjusted by the cooperation of the lifting screw 904, the rhomboid bearing 903, and the fixing nut 905. Since there is a certain amount of movement between the inner and outer rings of the rhomboid bearing 903, the spring roll entry angle at the front end of the rolling mechanism 9 can be slightly adjusted. Specifically, the lifting screw 904 at the front end of the lifting assembly is rotated to raise or lower the front end of the fixed side plate.

[0061] The working principle of this invention is as follows: Spring roll wrappers are conveyed forward on the front conveyor belt 14 and the middle belt 15. When they reach the filling mechanism 3 and are below the discharge mold 309, the servo motor starts. The output shaft of the servo motor drives the input shaft of the reducer 3024 to rotate. The output shaft of the reducer 3024 drives the drive gear to rotate. The drive gear drives the intermediate gear to rotate synchronously. The intermediate gear drives the transmission gear to rotate synchronously. The transmission gear drives the transmission shaft 3025 to rotate synchronously. The transmission shaft 3025 drives the drive pulley to rotate. The drive pulley drives the driven pulley to rotate synchronously through the transmission belt, thereby driving the drive shaft 3026 to rotate. The drive shaft 3026 drives the stirring shaft 3031 to rotate. The stirring shaft 3031 drives the V-shaped shaft 3032 to rotate to stir the filling, and at the same time drives the spiral blade 3033 to rotate to push the filling downward.

[0062] The filling enters the blocking slide hole 3062 through the spiral cylinder 305 and the feeding channel 3061, and then enters the pushing slide hole 3071 through the feeding port. After the filling is pushed, the piston rod of the blocking cylinder 313 pushes the blocking block 314 to slide in the blocking slide hole 314, and the blocking block 314 blocks the feeding channel 3061. Then, the piston rod of the pushing cylinder 315 pushes the pushing block 315 to move towards the discharge mold 309. The pushing block 315 pushes and extrudes the filling from the discharge port of the discharge mold 309. Finally, the piston rod of the cutting cylinder 310 drives the cutting blade 311 to move downward. The cutting blade 311 cuts the extruded filling, and the filling falls onto the spring roll skin, completing the filling of the spring roll skin. The whole action is completed in sequence. After the filling is completed, the cutting cylinder 310, the pushing cylinder 315, and the blocking cylinder 313 drive the cutting blade 311, the pushing block 315, and the blocking block 314 to return to their initial positions, respectively, to carry out the filling work of the next spring roll wrapper.

[0063] After the spring roll wrapper is filled, it continues to be conveyed forward on the front conveyor belt 14 and the middle conveyor belt 15. When it reaches the first folding mechanism 4, the rotary cylinder 402 drives the rotary shaft 403 to rotate. The rotary shaft 403 drives the two folding grippers 405 to rotate through the gripper sleeve 404. During the rotation of the folding grippers 405, the first fold of the spring roll wrapper is completed, so that the spring roll wrapper is folded in half and in close contact with the filling. Then it continues to be conveyed forward on the front conveyor belt 14 and the middle conveyor belt 15. When it reaches the crease mechanism 5, the two crease rollers 505 crease the spring roll wrapper.

[0064] The spring rolls then continue to be conveyed forward on the front conveyor belt 14 and the middle conveyor belt 15, and then on the two rear conveyor belts 16 for the second folding operation. Before the second folding mechanism 6 folds the spring rolls, the piston rod of the lifting cylinder 702 drives the lifting plate 703 to descend in advance. The lifting plate 703 drives the guide strip 705 to descend, and the guide strip 705 prevents the spring roll skin from being over-folded or folded off-center.

[0065] When the second folding mechanism 6 folds the spring rolls, the spring rolls are conveyed forward on the two rear conveyor belts 16. The first flipping and folding mechanism starts operating, the servo motor 6041 starts, and the output end of the servo motor 6041 drives the drive gear 6043 to rotate. The drive gear 6043 drives the driven gear 6044 to rotate synchronously, and drives the gear shaft and the drive pulley 6045 to rotate synchronously. Under the action of the driven pulley 6046, the synchronous belt 6047 is transmitted. The synchronous belt 6047 drives the moving plate 6061 to move to the right through the fixing member 6048. At this time, the linear bearing 6062 on the moving plate 6061 is guided by the sliding shaft 6. The moving plate 6061 moves to the right along with the synchronous belt 6047, so that the moving plate 6061 and the rear conveyor belt 16 have the same speed. While the moving plate 6061 moves to the right along with the synchronous belt 6047, the piston rod of the tilting cylinder 6064 drives the drive connecting rod 6066 to rotate. The drive connecting rod 6066 drives the irregular connecting rod 6067 to rotate through the rotating shaft. The connecting rod shaft at the end of the irregular connecting rod 6067 slides in the strip-shaped sliding hole, thereby causing the tilting seat 6068 to rotate upward. The tilting seat 6068 drives the mold plate 6069 to tilt upward. During the upward tilting process of the mold plate 6069, the spring roll folding action is completed, thereby completing the folding of the right side of the spring roll skin.

[0066] When the sensing plate 608 moves to the position above the sensor 607 on the right end of the moving plate 6031, the sensor 607 transmits a signal to the control box 10. The control box 10 controls the servo motor 6041 to reverse, and the synchronous belt 6047 transmits in reverse to restore the folding assembly 606 to its initial position. During this process, the flipping cylinder 6064 and the linkage structure work together to drive the mold plate 6069 to return to its initial state, waiting for the folding of the next spring roll skin.

[0067] The spring roll with the right side folded continues to be conveyed forward on the rear conveyor belt 16. When it reaches the position of the second folding mechanism, the second folding mechanism starts to operate and then completes the left side folding of the spring roll. The movement process is the same as that of the first folding mechanism.

[0068] After the spring roll completes the second folding, it continues to be conveyed forward on the rear conveyor belt 16 and moves to the centering mechanism at the end of the rear conveyor belt 16. The centering mechanism completes the centering operation of the spring roll through the centering push block 22 of the two centering components, so that the spring roll and the paste head 805 of the paste dispensing mechanism are on the same straight line. Then the spring roll continues to be conveyed forward on the rolling and conveying assembly 17.

[0069] When the spring roll is delivered to the grouting mechanism 8, the grouting cylinder 802 is activated. The piston rod of the grouting cylinder 802 drives the spring seat 803 and the grouting head 805 to descend. When the lower end of the grouting core 806 presses against the grouting position of the spring roll, the grouting core 806 is lifted by force, and the grout flows through the gap between the grouting core 806 and the grouting head 805 onto the spring roll skin. After the grouting operation is completed, the piston rod of the grouting cylinder 802 drives the spring seat 803 and the grouting head 805 to rise. Under the force of the spring 804, the grouting core 806 returns to its initial position to re-seal the grouting hole, preparing for the next grouting action.

[0070] The spring rolls, after being coated with slurry, continue to be conveyed forward on the rolling conveyor assembly 17 to the rolling mechanism 9. The spring rolls pass the rolling rod 908 at the front end of the fixed side plate 906, and undergo a pre-rolling action, which has a rolling pushing effect on the spring rolls and makes it easier for them to enter. Driven by the rolling conveyor assembly 17, the spring rolls are rolled through the friction between the spring rolls and the conveyor belt, the blocking force of the rolling rod 908, the downward pressure of the rolling rod 908 on the spring rolls, and the compaction effect of the previous rolling rod 908 during its descent. This process is repeated multiple times to make the rolled spring rolls more compact. During the process of the spring rolls being moved forward by the rolling conveyor assembly 17, the rolling rod 908 moves up and down under the guidance of the strip hole 907 after being hit by the spring rolls, which has the function of blocking and compacting the spring rolls. After passing through the rolling mechanism 9, the spring rolls are rolled into a round shape.

[0071] The embodiments described above are merely preferred embodiments of the invention and are not intended to limit the scope of the invention. Therefore, any equivalent changes or modifications made to the technical solutions described in the claims of this invention should be included within the scope of the patent application of this invention.
