Description

Technical Field

[0001] This utility model relates to the field of envelope bag production technology, and in particular to a glue spraying mechanism for an envelope bag making machine. Background Technology

[0002] Envelopes are bag-shaped packages used for mailing letters and protecting their contents. They are typically rectangular paper bags and serve the primary function of sealing letters, documents, and other items, while also providing protection and portability.

[0003] However, in the existing technology, the envelope bag needs to be sprayed with glue when sealing it. Since the glue spray nozzle sprays glue in a circular area, it often results in too much glue being sprayed, which affects the quality of sealing the envelope bag. Utility Model Content

[0004] The technical problem this invention aims to solve is that when sealing envelopes, glue needs to be sprayed onto the envelopes. Since the glue spray nozzle sprays out a circular area, too much glue is often sprayed out, which affects the quality of sealing the envelopes.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A glue spraying mechanism for an envelope bag making machine includes a glue spraying tube with a nozzle fixed at the bottom end. A shielding shell is wrapped around the bottom end of the glue spraying tube. Two adjusting baffles are rotatably installed on the bottom inner side of the shielding shell. Each adjusting baffle includes a limiting plate, and a guide plate is fixed at the bottom end of the limiting plate. A collection frame is provided below the guide plate, and the collection frame is fixedly connected to the shielding shell.

[0007] Preferably, the bottom end of the guide plate is always located above the collection frame, and the movement range of the guide plate does not exceed the length of the collection frame.

[0008] Preferably, one end of the rotating shaft extends through the shielding housing to the outside of the shielding housing, and a rotating shaft is fixed to the outside of this end of the rotating shaft, and an adjusting rack is engaged with the outside of the rotating shaft.

[0009] Preferably, an output gear is meshed between the close ends of the two adjusting racks, an adjusting motor is fixed to the axis of the output gear, and support plates are provided on both sides of the adjusting motor, with one end of the support plate fixedly connected to the shielding housing.

[0010] Preferably, a sliding plate is fixed to the side of the adjusting rack facing the shielding housing, and guide plates are provided above and below the sliding plate, and the guide plates are fixed to the shielding housing.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. By adjusting the angle of the two adjusting baffles located on the inner side of the bottom of the shielding shell, the distance between the bottom ends of the two adjusting baffles is changed, thereby changing the width of the adhesive spraying at the bottom of the shielding shell. This allows for adjustment of the adhesive spraying head according to the adhesive spraying requirements of different envelopes, preventing excessive adhesive spraying that could lead to accidents when sealing the envelopes.

[0013] 2. Use a guide plate to direct excess and sliding glue from the surface of the restriction plate into the collection box, preventing glue from dripping onto the envelopes. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 2 and Figure 4As shown, a glue spraying mechanism for an envelope bag making machine includes a glue spraying tube 1, a nozzle 3 fixed at the bottom end of the glue spraying tube 1, and a shielding shell 2 wrapped around the bottom end of the glue spraying tube 1. Two adjusting baffles 5 are rotatably installed on the inner side of the bottom end of the shielding shell 2. The adjusting baffles 5 include a limiting plate 51, a guide plate 52 fixed at the bottom end of the limiting plate 51, and a collection frame 4 below the guide plate 52. The collection frame 4 is fixedly connected to the shielding shell 2. By adjusting the angle of the two adjusting baffles 5 located on the inner side of the bottom end of the shielding shell 2, the distance between the bottom ends of the two adjusting baffles 5 is changed, thereby changing the glue spraying width at the bottom end of the shielding shell 2. This allows for adjustment of the glue spraying width according to the glue spraying requirements of different envelope bags, preventing excessive glue spraying that could lead to accidents when sealing the envelopes.

[0021] The bottom of the guide plate 52 is always located above the collection box 4. The movement range of the guide plate 52 does not exceed the length of the collection box 4. The guide plate 52 is used to guide the excess and sliding glue on the surface of the limiting plate 51 into the collection box 4, so as to prevent the glue on the surface of the limiting plate 51 from dripping onto the envelope.

[0022] As a preferred technical solution in this embodiment, such as Figure 1 and Figure 3 As shown, one end of the rotating shaft 6 extends through the shielding housing 2 to the outside of the shielding housing 2. The rotating shaft 6 is fixed to the outside of this end. An adjusting rack 11 is meshed on the outside of the rotating shaft 6. An output gear 9 is meshed between the close ends of the two adjusting racks 11. An adjusting motor 8 is fixed to the axis of the output gear 9. Support plates 10 are provided on both sides of the adjusting motor 8. One end of the support plate 10 is fixedly connected to the shielding housing 2. The adjusting motor 8 and the output gear 9 drive the two adjusting racks 11 to move, thereby causing the adjusting racks 11 to drive the adjusting gear 7 to rotate. This causes the rotating shaft 6 to drive the adjusting baffle 5 to rotate, thereby changing the distance between the bottom ends of the two adjusting baffles 5.

[0023] A sliding plate 13 is fixed to the side of the adjusting rack 11 facing the shielding housing 2. Guide plates 12 are provided above and below the sliding plate 13. The guide plates 12 are fixed to the shielding housing 2. The guide plates 12 support and guide the sliding plate 13, so that the adjusting rack 11 always maintains engagement with the adjusting gear 7 and the output gear 9 during the movement.

[0024] Working Principle: When using the glue spraying mechanism to spray glue onto envelopes, firstly, adjust the width of the glue outlet at the bottom of the glue spraying structure according to the sealing requirements of the envelopes. At this time, turn on the power of the adjusting motor 8 and start it. After the adjusting motor 8 starts, it drives the two adjusting racks 11 to move through the output gear 9. When the adjusting racks 11 move, they drive the adjusting gear 7 meshing with them to rotate. When the adjusting gear 7 rotates, it drives the rotating shaft 6 fixed to it to rotate. When the rotating shaft 6 rotates, the adjusting baffle 5 rotates. By rotating the adjusting baffle 5, the distance between the bottom ends of the two adjusting baffles 5 is changed. This ensures that when the glue enters the nozzle 3 through the glue spraying tube 1 and is sprayed out through the nozzle 3, the glue can only be sprayed out from the fixed distance between the bottom ends of the adjusting baffles 5. This achieves the adjustment of the glue spraying width. In this way, the glue spraying head can be adjusted according to the glue spraying requirements of different envelopes to avoid excessive glue spraying and accidents when sealing the envelopes.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
