It is one of the arts and crafts with a long history and tradition in the world. It has the effects of reducing noise, heat insulation, and decoration, improving foot feel, preventing slips, and preventing air pollution. It can also simplify floor construction, so it is popular among people. Whether it is a tufted carpet or a needle-punched carpet, it generally needs to be coated on the back with adhesive. This process is collectively called the back glue process. The uniformity of the carpet back glue application directly affects the quality of the carpet.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The gluing device for evenly applying glue in this embodiment includes a bracket body 1, a conveyor belt 11, a glue box device 2 and a heating box device 3. A gluing unit located between the heating box device 3 and the glue box device 2 is installed on the upper surface of the bracket body 1. The gluing unit includes a support frame 4 fixedly connected to the bracket body 1, a driving device is installed on the upper surface of the support frame 4, and a plurality of rotating rods 8 transmission-connected to the driving device are penetrated on the upper surface of the support frame 4, and a trowel plate 9 is fixedly connected to the lower end of the rotating rod 8.

[0024] like Figure 1-3As shown, the structure of the gluing device in the present invention is similar to the structure of the existing gluing device, such as a carpet back glue coating device disclosed in the patent with publication number CN216678852U. The main improvement of the present invention is to improve the uniformity of the gluing device on the carpet; the bracket body 1, conveyor belt 11, glue box device 2 and heating box device 3 in the present invention are all prior art, the conveyor belt 11, glue box device 2 and heating box device 3 are all installed on the bracket body 1, the glue box device 2 and the heating box device 3 are located above the conveyor belt 11, the conveyor belt 11 transports the carpet, the glue box device 2 is used to store glue and discharge glue, the pressure pump in the glue box device 2 makes the glue flow out from the gluing head in the glue box device 2 to the carpet transported by the conveyor belt 11 to complete the gluing, and the heating box device 3 is used to coat the glue on the carpet Drying after applying, the heat generated by the heating box driven by the blower of the heating box device 3 is used to dry the glue. The above are all existing technologies and their existing operating methods, which will not be described in detail here; when it is necessary to apply glue to the carpet, start the driving device to operate, place the carpet on the conveyor belt 11, and the conveyor belt 11 drives the carpet to move. The glue box device 2 applies glue to the upper surface of the carpet. When the upper glue part of the carpet moves to the bottom of the coating unit, the driving device drives multiple rotating rods 8 and the support frame 4 to rotate, and the rotating rod 8 drives the smearing plate 9 at its lower end to rotate, and the smearing plate 9 applies glue to the carpet. The smearing plate 9 can drive the glue on the carpet to spread and apply it evenly. The carpet after the glue is evenly applied can be moved to the heating box body 3 for drying. The overall structure is simple, which is convenient for applying glue to the carpet, and the glue is evenly applied, which is convenient for carpet production.

[0025] like Figure 2 , 3 As shown, the driving device includes a frame 5, a motor 6 and a plurality of gears 7. The frame 5 is fixedly mounted on the upper surface of the support frame 4. The plurality of gears 7 are respectively fixedly connected to the upper ends of the plurality of rotating rods 8. The output shaft of the motor 6 is fixedly connected to the upper surface of one of the gears 7. Two adjacent gears 7 are meshedly connected. When applying glue on the carpet, the motor 6 is started to work, and the motor 6 drives one of the gears 7 to move. The gear 7 drives the adjacent gear 7 to reverse through meshing, so that the plurality of gears 7 are rotated. The gear 7 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the trowel plate 9 to rotate. The two adjacent trowel plates 9 rotate in opposite directions. The trowel plates 9 evenly apply the glue on the carpet. The adjacent trowel plates 9 rotating in opposite directions can make the glue spread in more than one direction, thereby further increasing the uniformity of the glue application.

[0026] Among them, the above-mentioned motor 6 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The motor 6 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0027] like Figure 2 As shown, the support frame 4 includes a support plate 42 and two side plates 41, and the two side plates 41 are fixedly connected to the two sides of the upper surface of the support body 1 respectively. The upper surface of the side plate 41 is fixedly connected with a threaded rod 43, and the upper end of the threaded rod 43 passes through the support plate 42. The support plate 42 is slidably connected to the threaded rod 43. The outer wall of the threaded rod 43 is threadedly connected with two nuts 44, and the two nuts 44 are respectively located on the bottom surface and the upper surface of the support plate 42. The rotating rod 8 is rotatably connected to the support plate 42, and the frame 5 is installed on the support plate 42. The nuts 44 on the threaded rod 43 can be loosened according to the thickness of the carpet, so as to adjust the distance between the support plate 42 and the conveyor belt 11, and then the two nuts 44 are squeezed on the outer wall of the support plate 42 and tightened. The rise or fall of the support plate 42 can drive the trowel plate 9 to rise or fall through the rotating rod 8, so that it adapts to the thickness of the carpet, thereby increasing adaptability.

[0028] like Figure 2 As shown, a protective cover 12 is installed on the upper surface of the support plate 42 by bolts, the output shaft of the motor 6 is passed through the protective cover 12, and multiple gears 7 are located in the protective cover 12. The protective cover 12 can shield the multiple gears 7, so that when the gears 7 rotate, the protective cover 12 can shield and protect them to avoid injuries to people and objects when the gears 7 rotate.

[0029] like Figure 3 , 4 As shown, the rotating rod 8 includes a connecting rod 81 and a sleeve rod 82. The inner wall of the sleeve rod 82 is provided with a limiting groove 83. One end of the connecting rod 81 is slidably connected to the inner wall of the sleeve rod 82 and the limiting groove 83. The inner top wall of the sleeve rod 82 is fixedly connected with a spring 84. The other end of the spring 84 is fixedly connected to the upper end of the connecting rod 81. The lower end of the connecting rod 81 is fixedly connected to the upper surface of the trowel plate 9. The sleeve rod 82 is rotatably connected to the support plate 42. The gear 7 is fixedly connected to the upper end surface of the sleeve rod 82. When the gear 7 rotates, it drives the sleeve rod 82 to rotate. The sleeve rod 82 drives the connecting rod 81 to rotate through the limitation of the limiting groove 83. The connecting rod 81 drives the trowel plate 9 to rotate. The spring 84 can always give the connecting rod 81 a downward force, so that the connecting rod 81 drives the trowel plate 9 to always contact with the carpet, so that when the trowel plate 9 rotates, it always contacts with the glue on the carpet to spread it evenly.

[0030] like Figure 4As shown, an inclined groove 10 is provided on the bottom surface of the trowel plate 9, and the inclined angle of the inclined groove 10 is set at 45°. When the trowel plate 9 rotates, the inclined groove 10 on its bottom surface contacts the glue on the carpet to smooth it, which can avoid the glue overflowing to the side wall of the trowel plate 9 when the trowel plate 9 rotates.

[0031] like Figure 3 , 4 As shown, the distance between two adjacent sleeve rods 82 is less than the length of the trowel plate 9 and greater than half the length of the trowel plate 9. The two adjacent trowel plates 9 are staggered, and part of the movement trajectories of the two adjacent trowel plates 9 overlap. When the two adjacent trowel plates 9 rotate, their movement ranges overlap to a certain extent, and they rotate in an offset manner, so that the glue on the carpet can be evenly applied to reduce dead corners.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
