Description

Technical Field

[0001] The utility model belongs to the field of chrysanthemum packaging, in particular to a longitudinal heat sealing device of a chrysanthemum packaging machine. Background Art

[0002] To extend the shelf life and freshness of small, liquid solid particles like chrysanthemums, facilitate storage, and better meet the needs and usage of different consumers, chrysanthemums are packaged in small bags. The chrysanthemums are typically packaged in small portions. The process typically involves weighing the chrysanthemums, placing them into a film inner bag, and then placing the filled inner bag into an outer bag.

[0003] When packaging chrysanthemums into film inner bags, the film is typically sealed longitudinally using a longitudinal sealing mechanism, followed by a feeder barrel for quantitative bagging. Once bagging is complete, the film is then sealed transversely using a transverse sealing mechanism. However, existing longitudinal sealing mechanisms are typically fixed within the machine and cannot be disassembled, making them inconvenient for subsequent repair and maintenance. Furthermore, the longitudinal seal position of the film cannot be adjusted to meet actual requirements. Utility Model Content

[0015] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0017] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0018] Combine Figure 1-2 As shown, the longitudinal heat sealing device includes a machine 1, a stand 2 is provided inside the machine 1, a connecting plate 3 is provided inside the stand 2, a longitudinal heat sealing mechanism is provided in front of the connecting plate 3, a film pulling mechanism is provided on the back, a feeding barrel 4 is provided between the longitudinal heat sealing mechanism and the film pulling mechanism, the longitudinal heat sealing mechanism includes a fixed plate 5, the fixed plate 5 is mounted on the stand 2 through a connecting assembly, a pair of left and right longitudinal heat sealing plates are provided on the back of the fixed plate 5, the left longitudinal heat sealing plate is marked as 61, and the right longitudinal heat sealing plate is marked as 62. The right longitudinal heat sealing plate 62 can slide left and right, and the connecting assembly includes a pair of inner plates 7 mounted on the inner wall of the stand 2, the front end of the inner plate 7 is provided with a through hole (obstructed in the figure), and both ends of the fixed plate 5 are provided with a holder 8, the front end of the inner plate 7 is located in the holder 8 on the same side, and a pin 9 is inserted into the top of the holder 8, and the pin 9 passes through the through hole and out from the bottom of the holder 8.

[0019] In order to extend the shelf life and freshness of small solid particles such as chrysanthemums, packaging machines can be used to package chrysanthemums. Figure 3 In the process, when the chrysanthemums are packed into the film inner bag through the packaging machine, the film inner bag is close to the feeding barrel, so that the two sides of the film inner bag face the longitudinal heat sealing mechanism to form heat-sealed edges. The longitudinal heat sealing mechanism longitudinally seals the two overlapping heat-sealed edges. Then the film inner bag is pulled by the film pulling mechanism, and the chrysanthemums are poured into the packaging film that has completed the longitudinal edge sealing in a quantitative manner through the feeding barrel. Finally, the transverse heat sealing mechanism performs transverse edge sealing of the packaging film to complete the packaging of the chrysanthemums.

[0020] In this structure, if Figure 1 The longitudinal heat sealing mechanism includes a fixed plate 5, a pair of left and right side plates 10 are provided on the fixed plate 5, a pair of sliding rods 11 are provided between the side plates 10, and a slide plate 12 is commonly provided on the slide rods 11. The left and right longitudinal heat sealing plates are respectively installed on the left side plate and the slide plate 12, and a sliding cylinder (blocked in the figure) is provided on the right side plate for driving the slide plate to move left and right.

[0021] The overlapping heat-sealed edges of the film inner bag are located inside the left and right longitudinal heat-sealing plates. When the overlapping heat-sealed edges are longitudinally sealed using the longitudinal heat-sealing mechanism, the sliding cylinder drives the slide plate to move inward, that is, the right longitudinal heat-sealing plate moves toward the left longitudinal heat-sealing plate. The two longitudinal heat-sealing plates contact the overlapping heat-sealed edges of the film inner bag and perform longitudinal heat-sealing on them.

[0022] In this structure, the longitudinal heat-sealing mechanism can be removed from the machine, facilitating repair and maintenance. To disassemble the longitudinal heat-sealing mechanism, simply pull out the two latches and move the fixing plate outward until the two inner plates are free of the retaining bracket. This allows for quick and easy removal of the longitudinal heat-sealing mechanism.

[0023] As a preferred structure, Figure 1-2 The inner plate 7 is slidably mounted on the stand 2 , and a long slot 13 is provided on the side wall of the stand 2 . An adjusting bolt is screwed into the inner plate 7 , and the adjusting bolt is locked after passing through the long slot.

[0024] The mounting position of the longitudinal heat-sealing mechanism can be fine-tuned to adjust the longitudinal seal position of the film inner bag, improving the overall adaptability of the longitudinal heat-sealing mechanism. Specifically, a pair of slides 24 are provided within the upright frame, and the inner plates are slidably mounted within these slides. To fine-tune the mounting position of the longitudinal heat-sealing mechanism, simply loosen the two adjustment bolts. Pushing the fixed plate will cause the two inner plates to slide back and forth within their corresponding slides, and the two longitudinal heat-sealing plates will also move synchronously back and forth until they are adjusted to the desired position. The adjustment bolts can then be tightened.

[0025] During the above adjustment process, the adjusting bolt slides in the long slot, and the long slot plays a role in guiding and limiting the adjusting bolt, which can make the entire adjustment process more stable.

[0026] Further as a preferred structure, Figure 2 The film-drawing mechanism includes a pair of rotating shafts 14 rotatably mounted on the connecting plate 3, and a driving gear 15 and a rotating gear 16 are respectively provided on the rotating shafts 14, and the driving gear 15 and the rotating gear 16 are meshed. A rotating arm 17 is rotatably provided on the rotating shaft 14, and a connecting rod 18 is rotatably provided on the rotating arm 17. A film-drawing wheel 19 is provided at the front end of the connecting rod 18, and a linkage gear 20 is provided at the rear end, and the feeding barrel 4 is located between the two film-drawing wheels 19. A rotating cylinder 21 for driving the rotating arm 17 to rotate is rotatably provided on the connecting plate 3, and a driving motor 22 for driving the driving gear 15 to rotate is also provided in the machine 1.

[0027] Before the film inner bag is pulled by the film-pulling mechanism, the two film-pulling wheels need to be a short distance away from the feed barrel. The film inner bag is placed on the feed barrel and tightly attached to it, forming heat-sealed edges on both sides of the film inner bag, and the overlapping heat-sealed edges are located within the longitudinal heat-sealing plate. The rotating cylinder then drives the rotating arm inward until the two linkage gears engage with the drive gear and the rotating gear respectively. During this process, the two film-pulling wheels move toward the feed barrel and clamp the film inner bag. Finally, the drive motor drives the drive gear to rotate. Under the linkage of the various gears, the two film-pulling wheels rotate and pull the film inner bag downward.

[0028] Since the feeding barrel 4 is relatively smooth, Figure 1The side wall of the feed barrel 4 is vertically provided with a shallow groove 23 corresponding to the film pulling wheel 19. When the film pulling wheel moves toward the feed barrel and clamps the film inner bag, the film inner bag is located in the shallow groove, which can prevent the film inner bag from slipping during the pulling process and affecting its pulling effect.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
