[0032] In some other specific embodiments of the present utility model, the rest is the same as the above embodiments, except that, as Figure 7 shown, the film winding part 40 includes a rotating disk 4001, a grooved wheel 4002, a film winding motor 4003, a film winding driving pulley 4004, a film winding synchronous belt 4005 and a film roll 4006; the film winding motor 4003 is arranged on the frame 70, the film winding motor 4003 is connected to the film winding driving pulley 4004, the film winding synchronous belt 4005 is arranged on the film winding driving pulley 4004, the outer contour of the rotating disk 4001 is in close contact with the film winding synchronous belt 4005, the film roll 4006 is arranged on the rotating disk 4001, and the film winding motor 4003 drives the film winding synchronous belt 4005 to rotate through the film winding driving pulley 4004. The film winding synchronous belt 4005 makes the rotating disk 4001 rotate by friction, and the film roll 4006 rotates with the rotating disk 4001 to wind the product. One end of the film of the film roll 4006 is wound on the whole bundle of glass tubes 10 and is pressed by the pressing plate and the pressing block of the film breaking part 50. The film winding motor 4003 is started, the rotating disk 4001 rotates and drives the film roll 4006 to rotate, and the transverse part 20 cooperates to move horizontally while the film roll 4006 rotates to wind the stretch film on the whole bundle of glass tubes 10. After winding a certain area, the winding film adheres to the whole bundle of glass tubes 10 by its own adsorption force. At this time, the part pressed by the film breaking part 50 can be released to complete the subsequent winding.

[0033] In some other specific embodiments of the present utility model, the rest is the same as the above embodiments, except that, as Figure 7As shown, a plurality of limited grooved pulleys 2002 are in rolling connection with the outer periphery of the rotating disk 4001. The grooved pulleys 2002 can limit the position of the rotating disk 4001, prevent deviation, and play an auxiliary supporting role for the rotating disk 4001.

[0034] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 8 , Figure 9 and Figure 10 shown, the film breaking part 50 includes a pressing plate 5004, a first pressing block 5008, a second pressing block 5006, a cutting knife 5009 and a mounting plate 5010; a pressing plate cylinder 5002 is fixed in the middle of the mounting plate 5010, and a cutting knife cylinder 5007 and a second pressing block cylinder 5005 are respectively fixed on both sides of the pressing plate cylinder 5002; the first pressing block 5008 is fixed on the mounting plate 5010; the second pressing block 5006 can be driven by the second pressing block cylinder 5005 to linearly extend and retract, and when the second pressing block 5006 extends, the front end of the second pressing block 5006 forms a pressing plane with the front end of the first pressing block 5008; the cutting knife 5009 is arranged between the first pressing block 5008 and the second pressing block 5006 and can be driven by the cutting knife cylinder 5007 to linearly extend and retract; the pressing plate 5004 can be driven by the pressing plate cylinder 5002 to linearly extend and retract, and a pair of slideways are arranged on the mounting plate 5010, and a pair of auxiliary support rods 5003 are arranged in the slideways, and both sides of the pressing plate 5004 are connected to the auxiliary support rods 5003. The pressing plate cylinder 5002 drives the pressing plate 5004 to extend, and the pressing plate 5004 is separated from the two pressing blocks. The rotating disk 4001 drives the film roll 4006 to rotate and wind up. After the winding film 5001 falls, the rotating disk 4001 continues to drive the winding film 5001 to wind around the auxiliary support rods 5003. At this time, the second pressing block cylinder 5005 drives the second pressing block 5006 to be in the extended state, and the pressing plate cylinder 5002 drives the pressing plate 5004 to retract. The pressing plate 5004 presses the stretching film 5001 on the first pressing block 5008 and the second pressing block 5006, and the cutting knife cylinder 5007 drives the cutting knife 5009 to extend to cut the winding film 5001. Subsequently, the cutting knife cylinder 5007 drives the cutting knife 5009 to retract, and the second pressing block cylinder 5005 drives the second pressing block 5006 to retract again to release a section of the winding film 5001 that has been cut after winding. Then, after the product winding is completed, because the end face of the whole bundle of glass tubes 10 also needs to be covered with the plastic winding film 5001, when the winding film 5001 is wound, a section of length will be left between the winding film 5001 and the whole bundle of glass tubes 10 and extend out of the end face of the whole bundle of glass tubes 10. At this time, the other section of the winding film 5001 that has been cut is still pressed by the pressing plate 5004 and the second pressing block 5006 to wait for the next product to enter for film winding.

[0035] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 9As shown, the first pressing block 5008 and the second pressing block 5006 are rubber pressing blocks. Made of rubber material, they have a certain flexibility and will not cause damage to the equipment.

[0036] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 11 shown, the film arranging part 60 includes an upper brush 6009, a lower brush 6012, a left brush 6006 and a right brush 6003; the upper brush 6009, the lower brush 6012, the left brush 6006 and the right brush 6003 are respectively located in the four directions of up, down, left and right of the film winding part 40; upper cylinders 6007, lower cylinders 6010, left cylinders 6004 and right cylinders 6001 are respectively installed on the frame 70, and the upper cylinders 6007, the lower cylinders 6010, the left cylinders 6004 and the right cylinders 6001 respectively drive the brushes in the four directions through upper connecting rods 6008, lower connecting rods 6011, left connecting rods 6005 and right connecting rods 6002. The working process of the film arranging part 60 is as follows: When the film winding is completed, the plastic winding film 5001 extending out of the end face of the whole bundle of glass tubes 10 is in a free state and does not closely adhere to the end face of the whole bundle of glass tubes 10. Driven by the transverse moving part 20, the film arranging part 60 moves to the film arranging position. First, the right cylinder 6001 drives the right brush 6003 to extend out, squeezes and smears the stretching film on the end face of the whole bundle of glass tubes 10, and then the right cylinder 6001 retracts, driving the right brush 6003 back to the initial position. Then, according to the above principle, the left brush 6006, the upper brush 6009 and the lower brush 6012 sequentially smear the stretching film extending out of the end face on the end face, realizing the sealing of the end face of the whole bundle of glass tubes 10. After completing the above actions, the transverse moving part 20 drives the label placing part 30, the film winding part 40, the film cutting part 50 and the film arranging part 60 to retreat to the waiting position as a whole, and the whole bundle of glass tubes 10 enters the next working station along the conveying direction, and the above actions are cycled.

[0037] In some other specific embodiments of the present invention, the rest is the same as the above embodiments, except that, as Figure 11 shown, the widths of the left brush 6006 and the right brush 6003 are smaller than the height of the whole bundle of glass tubes 10, and the widths of the upper brush 6009 and the lower brush 6012 are larger than the width of the whole bundle of glass tubes 10. This ensures that after the left and right sides are smeared, when the upper brush 6009 and the lower brush 6012 smear the film on the end face, they can neatly smear the film above the films on the left and right sides, keeping the end face seal flat.

[0038] Certainly, the above embodiments are only for illustrating the technical concept and features of the present utility model. The purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model.
