Description

Technical Field

[0001] This utility model relates to the technical field of envelope sealing equipment, specifically a precision glue spraying component for envelope sealing equipment. Background Technology

[0002] After a letter or document is sealed in an envelope, it is delivered to the recipient by the post office or courier company, enabling the exchange of information between the sender and the recipient. Before being sent by courier, the envelope is usually sealed. Existing envelope sealing equipment sprays glue from a nozzle, and the sprayed glue is applied to the opening of the envelope to seal it.

[0003] However, existing envelope sealing equipment generally performs direct spraying, which causes the glue to spread during the spraying process, resulting in glue dripping onto other parts of the envelope and reducing the precision of the glue spraying. Therefore, it does not meet the current requirements. To address this, we propose a precision glue spraying component for envelope sealing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a precision adhesive spraying component for an envelope sealing device, in order to solve the problem mentioned in the background art that envelope sealing devices generally perform direct spraying, which causes the adhesive to disperse during the spraying process, resulting in the adhesive possibly dripping onto other parts of the envelope, thereby reducing the precision of the adhesive spraying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision glue spraying component for an envelope sealing device, comprising a device platform, with support columns fixedly connected to the four corners of the upper end of the device platform, a support frame plate fixedly connected to the upper end of the support columns, a glue storage tank in the middle of the support frame plate, multiple glue nozzles at the lower end of the glue storage tank, a limit strip fixedly connected to the front side of the upper end of the device platform, bottom slots on both sides of the upper surface of the device platform, a glue spraying component inserted between two bottom slots, and connectors inserted on both sides of the upper end of the glue spraying component, with a connector plate extending horizontally through the front end of the connector;

[0006] The adhesive spraying assembly includes two fixing parts inserted into the upper end of the bottom slot. The inner end of the fixing part is fixedly connected to a guide groove. Both sides of the surface of the fixing part are provided with limiting grooves. The middle of the limiting groove is provided with a transverse insertion hole.

[0007] The connector includes a U-shaped insert inserted into a limiting groove, a pulling block fixedly connected to the upper end of the U-shaped insert, and a second insertion hole extending laterally through the front and rear sides of the U-shaped insert.

[0008] Preferably, the cross-section of the U-shaped insert is an inverted U-shaped structure, and both sides of the U-shaped insert are inserted into the first insertion hole.

[0009] Preferably, the insertion holes are aligned, and the insertion plate is inserted into the first insertion hole.

[0010] Preferably, the upper and lower sides of the insertion hole inside the fixing part on the rear side are provided with inner grooves, and the inner grooves are fixedly connected with elastic clips.

[0011] Preferably, the upper and lower sides of the insert plate surface are provided with snap-fit ​​grooves, and the elastic clip is snapped into the snap-fit ​​grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, multiple glue nozzles at the lower end of the glue storage box are aligned with the upper end of the glue spraying assembly. The glue nozzles can spray glue into the guide groove, so the glue can flow downward along the guide groove. When the user places the envelope between the two limiting strips for restraint, the glue drips from the inside of the guide groove onto the surface of the envelope. This setting improves the accuracy of the glue nozzle spraying performance, and the setting of the two fixing parts also makes it difficult for the glue to spread outward.

[0014] 2. This utility model moves upward by pulling the pulling block and the U-shaped insert. During this movement, the U-shaped insert releases the restriction on the two fixed parts, allowing the two fixed parts to open. This makes it convenient for the user to clean the inside of the two fixed parts, thus preventing the inside of the guide groove from being blocked by dried and hardened glue.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 An embodiment of this utility model provides a precision glue spraying component for an envelope sealing device, comprising a device platform 1, with support columns fixedly connected to the four corners of the upper end of the device platform 1, a support frame plate 7 fixedly connected to the upper end of the support columns, a glue storage tank 5 located in the middle of the support frame plate 7, and multiple glue nozzles 6 located at the lower end of the glue storage tank 5, a limit strip 2 fixedly connected to the front side of the upper end of the device platform 1, bottom slots 8 located on both sides of the upper surface of the device platform 1, a glue spraying component 3 inserted between two bottom slots 8, and connectors 4 inserted on both sides of the upper end of the glue spraying component 3, with a connector plate 9 extending horizontally through the front end of the connector 4.

[0023] The adhesive spraying assembly 3 includes two fixing parts 301 inserted into the upper end of the bottom slot 8. The inner end of the fixing part 301 is fixedly connected to the guide groove 302. Both sides of the surface of the fixing part 301 are provided with limiting grooves 303. The middle of the limiting groove 303 is provided with a transverse insertion hole 304.

[0024] The connector 4 includes a U-shaped insert 401 inserted into the limiting groove 303. A pulling block 403 is fixedly connected to the upper end of the U-shaped insert 401. The front and rear sides of the U-shaped insert 401 are provided with second insertion holes 402. The cross-section of the U-shaped insert 401 is set as an inverted U-shaped structure. The two sides of the U-shaped insert 401 are inserted into the first insertion hole 304. The second insertion hole 402 and the insertion hole 304 are aligned. The insert plate 9 is inserted into the first insertion hole 304. In this configuration, the entire U-shaped insert 401 can be inserted into the limiting groove 303. This configuration allows the entire connector 4 to fix and connect the two fixing parts 301.

[0025] The upper and lower sides of the insertion hole 304 inside the rear fixing part 301 are provided with inner grooves 10. The inner groove 10 is fixedly connected with an elastic clip 11. The upper and lower sides of the surface of the insertion plate 9 are provided with snap-fit ​​grooves 12. The elastic clip 11 snaps into the snap-fit ​​groove 12.

[0026] In use, the two fixing parts 301 are first combined, wherein the U-shaped insert 401 can be inserted into the limiting groove 303, and the second insertion hole 402 on one side of the U-shaped insert 401 and the insertion hole 304 therein are aligned. Then, the insert plate 9 is inserted into the first insertion hole 304. When the insert plate 9 is inserted into the first insertion hole 304, the elastic clip 11 inside the inner groove 10 can be engaged in the snap-fit ​​grooves 12 on the upper and lower sides of the insert plate 9. Through this setting, the entire insert plate 9 can be restricted in the first insertion hole 304, thereby allowing the two fixing parts 301 to be combined and fixed. Then, the combined glue spraying assembly 3 is inserted into the bottom slot 8. The two sides of the lower end of the glue spraying assembly 3 are both provided with protruding block structures, so the protruding block structures on the two sides of the lower end of the glue spraying assembly 3 can be inserted into the bottom slot 8.

[0027] Multiple glue nozzles 6 at the lower end of the glue storage tank 5 are aligned with the upper end of the glue spraying assembly 3. The glue nozzles 6 can spray glue into the guide groove 302, so the glue can flow downward along the guide groove 302. When the user places the envelope between the two limiting strips 2 for restraint, the glue drips from the inside of the guide groove 302 onto the surface of the envelope. This setting improves the accuracy of the glue spraying performance of the glue nozzles 6, and the setting of the two fixing parts 301 also makes it difficult for the glue to spread outward.

[0028] After prolonged use, the adhesive in the overall glue spraying assembly 3 will gradually dry and harden inside the fixing part 301, causing it to become clogged. At this point, the insert plate 9 needs to be pulled forward to disengage the snap-fit ​​groove 12 on the inner side of the insert plate 9 from the surface of the elastic clip 11, thereby releasing the elastic clip 11 from limiting the overall insert plate 9. Simultaneously, the pulling block 403 and the U-shaped insert 401 are pulled upward. During this movement, the overall U-shaped insert 401 releases the limitation on the two fixing parts 301, allowing the two fixing parts 301 to open. This facilitates the user in cleaning the inner side of the two fixing parts 301, thus preventing the inner side of the guide groove 302 from being clogged by the dried and hardened adhesive.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
