Detailed Implementation

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] Example 1: As shown in the attached document Figures 1-4 As shown, the present invention relates to a glue gun pushing structure, including a sleeve 1, a lead screw 3 disposed in the glue-containing space 2 of the glue gun, and a push block 4. One end of the lead screw 3 is provided with a drive motor 5 for driving the lead screw 3 to rotate. The lead screw 3 is rotatably connected to the glue gun. The drive motor 5 is connected to the lead screw 3 through a coupling. The top of the front end of the sleeve 1 is hinged to the top of the front end face of the glue-containing space 2. The top of the front end of the sleeve 1 is connected to the glue gun. The rear end of the sleeve 1 can be lifted to facilitate the insertion of soft-packaged adhesive.

[0024] The pusher block 4 includes a pusher part 41 adapted to the sleeve 1 and a mounting part 42 disposed at the bottom end of the pusher part 41. The mounting part 42 is slidably connected to the glue-containing space 2, and a threaded hole 43 adapted to the lead screw 3 is provided on the mounting part 42. The pusher part 41 can slide back and forth in the sleeve 1. The bottom surface of the mounting part 42 abuts against the bottom surface in the glue-containing space 2 to prevent the mounting part 42 from flipping. A sliding groove adapted to the mounting part 42 can also be provided in the glue-containing space 2.

[0025] The bottom surface of the sleeve 1 is provided with a sliding groove 11 adapted to the mounting part 42. The length of the sliding groove 11 is the same as the length of the sleeve 1. The left and right sides of the sliding groove 11 are provided with downwardly extending limiting plates 12. The adhesive space 2 is provided with a positioning plate 21 adapted to the limiting plate 12. A positioning plate 21 is provided on the side of the two limiting plates 12 that are far apart. The distance between the two positioning plates 21 is fixed. The positioning plate 21 is fixed in the adhesive space 2. Preferably, the length of the positioning plate 21 is not less than the length of the sleeve 1. When the sleeve 1 is in a horizontal state, the two limiting plates 12 are located between the two positioning plates 21, and the distance between the outer sides of the two limiting plates 12 is the same as the distance between the inner sides of the two positioning plates 21 (the inner side is the side of the two objects that are close together, and the outer side is the side of the two objects that are far apart). The distance between the two limiting plates 12 is locked by the positioning plate 21 to prevent the sleeve 1 from deforming. The sleeve 1 is used to shape the adhesive of the flexible packaging and to prevent the adhesive of the flexible packaging from being twisted and deformed due to compression.

[0026] The sleeve 1 can be a cylinder, preferably, the cross section of the sleeve 1 is polygonal, further, the cross section of the sleeve 1 is regular polygonal, a sleeve 1 with regular octagonal cross section is shown in the drawings.

[0027] Further, in order to reduce the moving resistance of the push block, the push glue part 41 comprises a multi-prism 411 matched with the sleeve 1 and a protrusion 412 arranged on each edge of the multi-prism 411, the push glue part 41 and the sleeve 1 form linear contact operation, which can reduce the pushing resistance.

[0028] Preferably, when the sleeve 1 is in a horizontal state, the lead screw 3 is located inside the sliding groove 11, and when the soft package expands along the sliding groove 11, the lead screw 3 can provide certain support for the expanding soft package, reducing the degree of distortion of the soft package.

[0029] Preferably, the top of the front end of the sleeve 1 is hinged to the top of the front end face of the glue containing space 2 through a damping hinge.

[0030] Preferably, a stop ring 13 is arranged on the inner side of the front end of the sleeve 1, and the inner diameter of the stop ring 13 is smaller than the outer diameter of the soft package. Since the inner diameter of the sleeve 1 is larger than the outer diameter of the soft package, when loading, the soft package will slide down along the sleeve 1, and there is a problem of touching the lead screw 3. Therefore, a stop ring 13 is arranged to avoid the soft package from touching the lead screw.

[0031] Preferably, the length of the glue containing space 2 is greater than the sum of the thickness of the push glue part 41 and the length of the sleeve 1, which facilitates lifting the rear end of the sleeve 1 and facilitates loading the soft package.

[0032] Because the packaging material of the soft package will produce concave wrinkles and folds during compression, the diameter of the adhesive in the package will change to a certain extent. With the compression, the more wrinkles and folds, the more severe the change in the diameter of the adhesive, the smaller it becomes. Especially when one side of the compression is close to the end and the other side is a newly placed package, the diameter difference of the adhesive in the soft package is most obvious. For a two-component glue gun, in the case of using soft packages with the same diameter, the pushing ratio of the adhesive is realized by the pushing speed ratio. If the soft package produces concave wrinkles and folds, the diameter of the adhesive in the package will gradually decrease, so that the pushing distance and the volume of the pushed adhesive are no longer in a linear relationship, causing the set pushing ratio to be inaccurate. The greater the difference between the left and right pushing positions, the more serious the distortion of the ratio. If the pushing speed gradually increases during the pushing process, compensation should be made, such as stepwise speed-up, which is 20% faster at the end of compression than at the beginning of the first section.

[0033] Specifically, one or more control switches 22 are arranged at the front of the glue accommodating space 2, the control switches 22 can be proximity switches or other position sensors, after the control switches 22 detect the push block 4, the rotation speed of the driving motor 5 is controlled to increase.

[0034] The mounting portion 42 is provided with a touch block 44 matched with the control switch 22, the control switch 22 can be arranged on the inner wall of the glue accommodating space 2, when the push block 4 moves, the touch block 44 contacts with the control switch 22, so that the control switch 22 is triggered.

[0035] Embodiment 2: The utility model discloses a two-component glue gun which adopts the glue pushing structure in embodiment 1, is provided with a glue accommodating space 2 on the glue gun, the middle part of the glue accommodating space 2 can be separated by a partition plate or not, two sets of glue pushing structures are arranged in the glue accommodating space 2, the lead screw 3 is rotationally connected with the glue gun, and the driving motor 5 is fixed on the glue gun through screws.
