[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] Example 1

[0026] A gantry gluing device with a detachable screen plate comprises a gluing platform and a gluing device arranged on a gantry 1, wherein the gantry 1 is gantry-shaped, which improves the stability of the gluing, and the gluing device comprises a driving mechanism and a scraping mechanism driven by the driving mechanism to move up and down, wherein the scraping mechanism comprises a positioning frame 2 and a rodless cylinder 3 mounted on the positioning frame 2, the rodless cylinder 3 drives the gluing assembly to move left and right along the positioning frame 2, the gluing assembly comprises a first gluing unit 4 and a second gluing unit 5, each of the gluing units comprises a small cylinder 6 and a scraping plate 7 driven by the small cylinder 6 to move up and down, a glue groove 8 is fixed below the positioning frame 2, and screen clamps 9 are mounted on the left and right sides of the glue groove 8, and the screen is fixed in the glue groove 8 by the screen clamps 9. The screen clamps 9 are bar clamps with high fixing stability.

[0027] Select a suitable screen plate according to the shape and size of the window of the packaging box, and fix the screen plate in the glue groove 8 by using the screen clamp 9. The screen plate is detachable and suitable for gluing operations of packaging boxes of different models. The glue is located above the screen. When in use, the packaging box to be glued is transferred to the gluing platform, and the driving mechanism drives the entire scraper mechanism to move downward, pressing the packaging box to be glued between the scraper mechanism and the gluing platform. The rodless cylinder 3 drives the gluing assembly to move left and right, and scrapes the glue on the screen onto the packaging box. When the gluing assembly moves left and right, the scraper plate 7 of the first gluing unit 4 descends, and the scraper plate 7 of the second gluing unit 5 does not descend. When moving from left to right, the scraper plate 7 of the first gluing unit 4 scrapes the ink from the screen and leaks it onto the paper box to complete the gluing. At this time, there is still some glue left on the screen, which is between the two scrapers 7. Then, when the first gluing unit 4 and the second gluing unit 5 return, the scraper plate 7 of the first gluing unit 4 rises, and the scraper plate 7 of the second gluing unit 5 descends, and the same action is performed to scrape the glue.

[0028] Preferably, the length of each scraper 7 is the same as the width of the glue groove 8. Furthermore, each glue coating unit includes two small cylinders 6, which drive one scraper 7 to move up and down. The two small cylinders 6 are symmetrically arranged at the front and rear ends of the scraper 7.

[0029] Example 2

[0030] The driving mechanism includes a cylinder 11 mounted on the gantry 1. The scraper mechanism is driven by the cylinder 11 to move up and down. A guide sleeve 12 is also fixed on the gantry 1. A guide column 13 fixed on the scraper mechanism is inserted into the guide sleeve 12. The guide column 13 and the guide sleeve 12 constitute a guide assembly to ensure that the scraper mechanism moves up and down in a straight line in the vertical direction.

[0031] Example 3

[0032] A pressure plate 10 is fixed on the gluing platform, and holes are evenly distributed on the pressure plate 10. The pressure plate 10 is located below the gluing mechanism to reduce the gluing error caused by machine vibration, ensure the pressure stability during the gluing process, and make the gluing process smooth so that the gluing thickness is uniform and the gluing accuracy is improved.

[0033] More preferably, the pressure plate 10 is detachably fixed on the glue coating platform to facilitate replacement or cleaning.

[0034] More preferably, the thickness of the pressure plate 10 is 8 mm, and the pressure plate 10 is an aluminum plate or a steel plate.

[0035] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0036] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
