[0035] Furthermore, the present invention also provides a fully automatic straw coating and filling machine, which includes a workbench 1, a straw mold 2, a lower tube assembly 3, an automatic tube alignment assembly 4, a filling assembly, a coating assembly, a sealing assembly, an artificial operation table 7, and a straw body 8. A frame 12 is provided on the lower side of the workbench 1, and conveying side plates 11 are symmetrically arranged on the upper side of the workbench 1. Driving wheels are arranged between the conveying side plates 11. The driving wheels are arranged in pairs, and a belt or a chain is sleeved outside the driving wheels. The straw mold 2 is driven by the belt or the chain. The lower tube assembly 3 is arranged at one end of the belt. The automatic tube alignment assembly 4, the filling assembly, the coating assembly, and the sealing assembly 6 are sequentially arranged on both sides of the belt along the length direction of the belt. The artificial operation table 7 is fixedly arranged on the workbench 1, and a controller is arranged in the artificial operation table 7. The straw body 8 is arranged in the hopper 31 of the lower tube assembly 3, and a straw positioning groove 21 is correspondingly arranged on the straw mold 2. The straw body 8 is stuck in the straw positioning groove 21 and moves along with the straw mold 2. A plurality of straw positioning grooves 21 are arranged on each group of straw molds 2 for synchronous processing. The filling assembly is provided with a filling head to add raw materials to the end of the straw body 8. The coating assembly is provided with a coating head, and the coating head moves along the length direction of the straw body 8 to evenly coat the extruded raw materials on the tube wall of the straw body 8. The artificial operation table 7 is provided with a controller. The driving wheels are driven by a driving motor, and the driving motor is electrically connected to the controller.

[0036] Example 1: The straw body 8 is arranged in the conical hopper 31 and finally falls into the lower tube outer sleeve 32 from the bottom of the hopper 31 and cooperates with the lower tube mold 33 in the lower tube outer sleeve 32, being stuck in the material distribution groove of the lower tube mold 33. The lower tube mold 33 rotates, so as to move the material distribution groove with the straw body 8 away and let it leak from the bottom and fall on the straw mold 2. The straw mold 2 moves along with the belt, so as to move the suction rack 2 with the straw body 8 away. The rotation speed of the lower tube mold 33 and the moving speed of the straw mold 2 can be regulated through the controller, so that the two cooperate with the subsequent components to work in a programmed manner.

[0037] After the straw mold 2 moves between the automatic tube alignment assemblies 4, the controller controls the first cylinder to work, driving the positioning plate 42 to move towards the straw mold 2, thereby pushing the straw bodies 8 to align them with each other.

[0038] After the straw mold 2 moves between the filling and coating components 5, the controller controls the operation of the third cylinder to drive the straw lifting positioning frame 58 to move, lifting the straw body 8 upward; at the same time, the controller controls the operation of the second cylinder to drive the fixed plate 53 to move downward, so that the connecting plate 54 drives the first pressing plate 55 to move downward. The pressing blocks on the first pressing plate 55 cooperate with the pressing blocks on the straw lifting positioning frame 58 to clamp the straw body 8 and fix it. Then, the controller controls the pipe positioning seat 56 to clamp, closing one end of the straw body 8. In this way, the straw body 8 is further fixed to prevent it from sliding under the action of external forces during the filling and coating process and affecting the filling effect. Finally, the servo motor 57 drives the filling and coating pipe 51 to translate and penetrate into the straw body 8 from the unclosed end; the filling and coating pipe 51 first moves to the closed end of the straw body 8, and then the filling material in the filling and coating pipe 51 flows out through the filling and coating head 52; then the filling and coating pipe 51 moves along the inside of the straw body 8 under the drive of the servo motor 57 and is pulled outwards, so that there is a uniform gap between the spherical structure of the filling and coating head 52 and the straw body 8. During the movement, the raw material is pushed to coat the inner wall of the straw body 8 to form a coating. Finally, the filling and coating pipe 51 is removed from the straw body 8, the pipe positioning seat 56 is loosened, and the straw lifting positioning frame 58 drops, so that the straw body 8 falls back onto the straw mold 2, facilitating the next operation.

[0039] After the straw mold 2 moves between the sealing components 6, the controller controls the operation of the fourth cylinder to drive the second lifting plate 61 to move downward, so that the pressing block on the second pressing plate 62 clamps the straw body 8; then the fifth cylinder drives the sealing mold seat 63 to move, so that the sealing groove on the sealing mold seat 63 aligns with the straw body 8 and performs the hot melt sealing work; after the sealing work is completed, the sealing mold seat 63 and the second pressing plate 62 are removed; the straw mold 2 continues to move to complete the entire processing process.

[0040] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that the filling and coating component 5 in Embodiment 1 is replaced by a split filling component and coating component, and the filling and coating work in Embodiment 1 is divided into filling work and coating work respectively to meet different work requirements.

[0041] Embodiment 3: The difference between Embodiment 3 and Embodiment 1 is that the filling and coating head 52 moves repeatedly in the straw body 8 for coating to ensure the uniformity and stability of the coating.

[0042] In Embodiment 1, Embodiment 2, and the embodiment, the filling volume can be accurately controlled, and the coating length and speed can be set on the manual operation table 7.

[0043] It should be noted that the entire device is controlled through the total control button. Since the devices matched with the control button are common devices and belong to the existing mature technologies, the electrical connection relationships and the specific circuit structures thereof will not be elaborated herein.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
