Description

Technical Field

[0001] This utility model relates to the field of spring roll wrapping technology, specifically to a spring roll wrapping forming machine. Background Technology

[0002] Spring rolls, also known as spring pancakes, spring platters, or thin pancakes, are made by preparing the wrappers, preparing the filling, filling the wrappers, folding and rolling the wrappers, and packaging them. During the production process, after folding the wrappers and before rolling them, a paste is applied to the wrappers to prevent the rolled spring rolls from opening or becoming loose. Existing technologies typically use nozzles to apply paste to spring roll wrappers, then use high-pressure air to atomize and spray the paste, covering the wrapper. However, this method suffers from the drawback of excessive paste coverage, leading to paste waste. Current spring roll forming devices often use herringbone mesh and B-type mesh to roll the spring rolls into a round shape. After folding, the spring rolls pass under the herringbone mesh and B-type mesh via conveyor belts, relying on friction between the spring rolls and these meshes to form the rolls. However, the success rate is greatly affected by the spring roll's entry angle and the weight of the mesh belts. Herringbone mesh and B-type mesh rolling are often used in air-blowing spring roll production equipment, where the spring roll wrappers are softer and require less force during rolling. In contrast, mechanically rolled spring rolls have increased hardness and thickness. When using herringbone mesh and B-type mesh to roll spring rolls, the resulting rolls are not tight enough, thus reducing the success rate.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN222442919U discloses a spring roll forming device, comprising a conveying mechanism, a paste-dispensing mechanism, and a rolling and rounding mechanism mounted on a support frame. The paste-dispensing mechanism includes a lifting assembly and a paste-dispensing nozzle assembly, the lifting assembly being connected to the paste-dispensing nozzle assembly. The paste-dispensing nozzle assembly includes a spring seat, a paste-dispensing head, and a paste-dispensing core. A spring tube seat is connected to the paste-dispensing head. A spring is disposed within the spring seat. The paste-dispensing core is sleeved within the spring seat and the paste-dispensing head. A paste-dispensing hole is formed at the bottom of the paste-dispensing head. The rolling and rounding mechanism includes a gantry frame and a rolling and rounding assembly. An adjusting assembly is disposed on the gantry frame and connected to the rolling and rounding assembly.

[0004] While the aforementioned existing technical solutions can effectively reduce the area of ​​the paste applied to the spring roll wrapper and reduce paste waste, and can roll spring rolls of different sizes, the rolling rod is directly fitted inside the long hole and slides in the hole. This cannot guarantee that it will not deviate or slip when avoiding the spring roll. Furthermore, because the rolling rod lacks restraint and pressure when sliding inside the long hole, and its surface does not have holes or recesses like those on herringbone mesh or B-type mesh to pull the spring roll surface, the rolling rod may completely avoid the spring roll wrapper without sufficient pressure and friction. This makes it impossible to achieve the operation of squeezing and guiding the spring roll for traction and winding in conjunction with the conveyor's conveying direction, thus affecting the spring roll forming effect. Utility Model Content

Furthermore, because the rolling rod lacks restraint and pressure when sliding inside the long hole, and its surface does not have holes and depressions like those on herringbone mesh and Z-type mesh to pull the spring roll surface, the rolling rod may completely avoid the spring roll skin without sufficient pressure and friction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A spring roll wrapping and forming machine includes a conveyor body 1, a support frame 2 installed at one end of the outer wall of the conveyor body 1, and overlapping frames 3 installed on both sides of the outer wall of the conveyor body 1 at one end of the support frame 2. A movable forming mechanism is installed on the support frame 2 and the overlapping frames 3. The movable forming mechanism includes a placement frame 4, a locking assembly, and a spring-loaded forming assembly. The placement frame 4 overlaps the top of the overlapping frame 3. One end of the support frame 2 is fixedly connected to the outer wall of the placement frame 4. The locking assembly is used to lock the positions of the placement frame 4 and the overlapping frame 3. The spring-loaded forming assembly assists in the wrapping and forming of the spring roll. In use, the machine can lock the positions of the placement frame 4 and the overlapping frame 3 using the locking assembly, and the spring-loaded forming assembly assists in the wrapping and forming of the spring roll. The machine has a simple structure, is easy to operate, and applies sufficient downward pressure to ensure sufficient friction between the spring roll and the forming column 6, allowing the spring roll to be wrapped and formed, further improving the forming effect.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the spring-loaded forming assembly includes multiple sets of movable grooves opened at opposite ends of the overlapping frame 3 and the placement frame 4. Movable columns 5 are slidably connected to the inner side of the movable grooves. Forming columns 6 are installed at opposite ends of the two sets of opposite movable columns 5. The diameter of the forming column 6 is larger than the diameter of the movable column 5. A sliding groove is opened on one side of the inner wall of the movable groove. A sliding plate 7 is slidably connected to the inner side of the sliding groove. The cross-section of the sliding plate 7 and the sliding groove is T-shaped. A sliding spring 8 is installed between the sliding plate 7 and the inner wall of the sliding groove. A lower pressure plate 9 is installed at one end of the sliding plate 7 extending to the inner side of the movable groove. A lower pressure groove is opened at one end of the outer wall of the movable column 5. One end of the lower pressure plate 9 is engaged with the lower pressure groove. First, the conveyor body 1 can convey the spring roll to the overlapping frame 3. The spring roll contacts the outer wall of the forming column 6. The forming column 6 rolls accordingly, and the sliding plate 7 moves inside the sliding groove to squeeze the sliding spring 8. This avoids the spring roll from being directly flattened without damaging its forming.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the locking assembly includes a slot at one end of the top of the overlapping frame 3, and a block 10 slidably connected to the slot at the bottom of the placement frame 4. An abutment groove is provided inside the overlapping frame 3 on one side of the slot, and the inner side of the abutment groove is connected to the inner side of the slot. An abutment plate 11 is slidably connected to the inner side of the abutment groove. Then, as the conveyor body 1 conveys, the edge of the spring roll contacts the arranged forming columns 6. The sliding plate 7, in conjunction with the sliding groove, can stabilize the movement trajectory of the forming column 6 and the movable column 5. The sliding spring 8 can provide sufficient downward pressure. The pressure plate 9 is inserted into the pressure groove to prevent the forming column 6 from deflecting randomly, ensuring that the friction between the spring roll and the forming column 6 can wrap the spring roll and form it, thus ensuring the forming effect.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, first springs 12 are installed at both ends of one side of the abutting plate 11 and between the inner wall of the abutting groove. A pull rod 13 is installed on one side of the abutting plate 11 between the two sets of first springs 12. An operating groove is opened on the top of the overlapping frame 3 on the side of the slot. A pull groove that is slidably connected to the pull rod 13 is opened inside the overlapping frame 3 on the side of the abutting groove. A pull ring 14 is rotatably connected to the end of the pull rod 13 near the operating groove. The cross-section of the abutting plate 11 is T-shaped, and the cross-section of the locking block 10 is L-shaped. Corresponding inclined surfaces are opened at the opposite ends of the abutting plate 11 and the locking block 10. A protective groove is provided on one side of the top of the operating groove. A protective plate 15 is slidably connected to the inside of the protective groove. Limiting grooves 16 are provided on both sides of the inner wall of the protective groove. Limiting blocks that are slidably connected to the limiting grooves 16 are installed at both ends of the protective plate 15. Furthermore, by fastening the pull ring 14, the pull rod 13 can be moved inside the pull groove, so that the abutting plate 11 is away from the protruding end of the locking block 10, forcing the two sets of first springs 12 to retract. At this time, the placement frame 4 can be lifted upward, and the lower pressure plate 9 is away from the inside of the lower pressure groove. At this time, the movable column 5 and the forming column 6 can be removed together for inspection and maintenance.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a drag groove is provided on one side of the protective plate 15, and a magnetic block 17 is embedded in one end of the protective plate 15. A corresponding iron block is embedded in one side of the inner wall of the operating groove. Furthermore, after maintenance is completed, the placement frame 4 can be overlapped on the overlapping frame 3 again. After the card block 10 enters the inside of the card groove, it contacts the abutment plate 11. The inclined surfaces of the two forces the abutment plate 11 to retract into the inside of the abutment groove. After the card block 10 is fully pushed in, the first spring 12 drives the abutment plate 11 to pop out and abut the card block 10, thus locking the placement frame 4. After locking, the drag groove can be fastened together with the limiting groove 16 and the limiting block to drive the protective plate 15 to cover the port of the operating groove. At this time, the magnetic block 17 and the iron block attract each other to position the protective plate 15 and protect the pull ring 14 to prevent personnel from accidentally touching it.

[0028] The implementation principle of a spring roll wrapping forming machine according to this application embodiment is as follows: The conveyor body 1 can convey the spring rolls towards the overlapping frame 3. The spring rolls contact the outer wall of the forming column 6, and the forming column 6 rolls accordingly. At the same time, the sliding plate 7 moves inside the sliding groove, thereby squeezing the sliding spring 8. This avoids the spring rolls from being directly flattened without damaging their forming. As the conveyor body 1 conveys, the edges of the spring rolls contact the arranged forming columns 6. The sliding plate 7, in conjunction with the sliding groove, can stabilize the movement trajectory of the forming column 6 and the movable column 5. The sliding spring 8 can provide sufficient downward pressure. The lower pressure plate 9 is inserted into the lower pressure groove to prevent the forming column 6 from deflecting arbitrarily. This ensures that the friction between the spring roll and the forming column 6 allows the spring roll to be wrapped and formed, guaranteeing the forming effect. Fastening the pull ring 14 can drive the pull rod 13 to move inside the pull groove. The abutment plate 11 is moved away from the protruding end of the locking block 10, forcing the two sets of first springs 12 to retract. At this time, the placement frame 4 can be lifted upwards, and the lower pressure plate 9 is moved away from the inner side of the lower pressure groove. At this time, the movable column 5 and the forming column 6 can be removed together for inspection and maintenance. Conversely, after maintenance, the placement frame 4 can be reattached to the overlapping frame 3. After the locking block 10 enters the inner side of the slot, it contacts the abutment plate 11. The inclined surfaces of the two forces the abutment plate 11 to retract to the inner side of the abutment groove. After the locking block 10 is fully pushed in, the first spring 12 drives the abutment plate 11 to pop out and abut the locking block 10, thus locking the placement frame 4. After locking, the drag groove can be fastened together with the limit groove 16 and the limit block to drive the protective plate 15 to cover the port of the operating groove. At this time, the magnetic block 17 and the iron block attract and position the protective plate 15, protecting the pull ring 14 to prevent personnel from accidentally touching it.

The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
