[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 3 - Figure 5, an embodiment provided by the present utility model: a sponge gluing device, including a base 1, a conveyor 2 is fixedly connected to the top of the base 1, enabling the sponge to move horizontally for gluing. The conveyor 2 is a prior art and will not be described in detail here. An adjusting mechanism is provided at the front end of the conveyor 2. The adjusting mechanism includes a square column 8. Three sets of notches are provided on the inner wall of the square column 8, and the distance between each notch is 30 cm, corresponding to the widths of three conventional mattress sponges, which are 1.2 m, 1.5 m, and 1.8 m respectively. A threaded rod 7 is threadedly connected to the inner wall of the square column 8, enabling the threaded rod 7 to rotate within the inner wall of the square column 8 for further precise adjustment. An L-shaped plate 18 is fixedly connected to the front end of the square column 8, so that when the L-shaped plate 18 moves horizontally, the square column 8 can be driven to move together. The inner wall of the L-shaped plate 18 is threadedly connected to the outer wall of the threaded rod 7, enabling the threaded rod 7 to rotate within the inner wall of the L-shaped plate 18. When the L-shaped plate 18 is pulled to move horizontally, the threaded rod 7 can be driven to move simultaneously. The outer wall of the square column 8 is slidably connected to the inner wall of the front end of the conveyor 2, enabling the square column 8 to slide horizontally within the inner wall of the conveyor 2 to change the clamping space of the square plate 9. A square block 11 is slidably connected to the inner wall of the front end of the conveyor 2, enabling the square block 11 to slide vertically within the inner wall of the conveyor 2. The conveyor 2 provides a supporting effect for the square block 11. The bottom of the square block 11 is inclined. A wedge block 12 is slidably connected to the outer wall of the bottom of the square block 11, so that when the square block 11 moves vertically, the wedge block 12 can be driven to move horizontally. An inclined notch is provided on the right side of the wedge block 12, which fits the inclined surface of the square block 11. The outer wall of the wedge block 12 is slidably connected to the inner wall of the front end of the conveyor 2, enabling the wedge block 12 to slide horizontally within the inner wall of the conveyor 2. The conveyor 2 provides a supporting effect for the wedge block 12.

[0033] Refer to Figure 2 - Figure 4, the inner wall on the right side of the square column 8 is inserted into the outer wall on the left side of the wedge block 12, so that the wedge block 12 can fix the position of the square column 8. The rear end of the threaded rod 7 is rotatably connected to a square plate 9, so that the square plate 9 can be driven to move simultaneously when the threaded rod 7 moves horizontally. A guiding round rod is fixed to the outer wall of the square plate 9 to maintain the stability of the square plate 9 during sliding. The guiding round rod passes through the front end of the conveyor 2 and slides with it, and at the same time passes through the left side of the L-shaped plate 18 and slides with it. There are two groups of square plates 9, and the other group is fixedly connected to the outer wall at the rear end of the conveyor 2. A pulley 10 is rotatably connected to the inner wall of the square plate 9, so that the square plate 9 provides a supporting and fixing effect for the pulley 10. There are multiple groups of pulleys 10, so that the clamped mattress sponge can slide over the pulleys 10. The top of the L-shaped plate 18 is fixedly connected to a piston 15, so that the piston 15 can be driven to move simultaneously when the L-shaped plate 18 moves horizontally. The piston 15 is made of elastic rubber and can effectively seal the glue spraying cylinder 5. The outer wall of the piston 15 is slidably connected to the glue spraying cylinder 5, so that the capacity of the glue spraying cylinder 5 can be changed when the piston 15 moves horizontally. A feed port is provided at the top of the glue spraying cylinder 5, and multiple groups of nozzles are provided at the bottom of the glue spraying cylinder 5. When the piston 15 moves, it can limit the operation of the nozzles at the bottom of the glue spraying cylinder 5, so that the range of the glue sprayed is adapted to the size of the mattress sponge. The rear outer wall of the glue spraying cylinder 5 is fixedly connected to a frame 3, so that the frame 3 provides a supporting and fixing effect for the glue spraying cylinder 5. Multiple groups of rollers are provided at the top of the frame 3. Pull another piece of mattress sponge that needs to be glued and slide it over the mattress sponge on the conveyor 2, and squeeze and glue them together through the pressure roller 14. The outer wall on the right side of the wedge block 12 is elastically connected to the inner wall at the front end of the conveyor 2 through a spring A13. One end of the spring A13 is fixedly connected to the outer wall on the right side of the wedge block 12, and the other end of the spring A13 is fixedly connected to the inner wall at the front end of the conveyor 2. So that after pressing the square block 11 to drive the wedge block 12 to slide horizontally, the wedge block 12 can be reset by the elasticity of the spring A13 without external force, and then inserted into the notch of the square column 8.

[0034] Refer to Figure 1 , Figure 4, the top of the base 1 is fixedly connected to the bottom of the frame 3, so that the base 1 provides a supporting and fixing effect for the frame 3 to maintain the stability of the frame 3 during operation. A fixing frame 4 is fixedly connected to the top of the base 1, so that the base 1 provides a supporting and fixing effect for the fixing frame 4. The fixing frame 4 is U-shaped. A motor 6 is fixedly connected to the front end of the fixing frame 4, so that the fixing frame 4 can maintain the stability of the motor 6 during operation. The output shaft of the motor 6 is fixedly connected to a pressure roller 14, so that the output shaft of the motor 6 can drive the pressure roller 14 to rotate. Two groups of pressure rollers 14 are arranged up and down, so that two pieces of mattress sponges can be extruded to make their gluing more firm. The outer wall of the front end of the pressure roller 14 is rotatably connected to the inner wall of the front end of the fixing frame 4, so that the pressure roller 14 can rotate inside the inner wall of the fixing frame 4. The fixing frame 4 provides a supporting effect for the pressure roller 14. A disc 17 is slidably connected to the inner wall of the pressure roller 14, so that the disc 17 can slide horizontally inside the inner wall of the pressure roller 14 to limit two pieces of mattress sponges to be glued, preventing them from shaking left and right when being extruded. The outer wall of the front end of the disc 17 is elastically connected to the inner wall of the front end of the pressure roller 14 through a spring B16. One end of the spring B16 is fixedly connected to the outer wall of the front end of the disc 17, and the other end of the spring B16 is fixedly connected to the inner wall of the front end of the pressure roller 14, so that the disc 17 is elastically pushed by the spring B16 to limit mattress sponges of different sizes.

[0035] Working principle: The staff places the mattress sponge on the conveyor 2, moves the L-shaped plate 18 inward, drives the square column 8 to move simultaneously, drives the square plate 9 to move, and at the same time drives the piston 15 to move to adjust the spraying range of the nozzle on the glue spraying cylinder 5. The square column 8 is fixed by the wedge block 12, and the position of the square plate 9 can also be precisely adjusted by rotating the threaded rod 7. Thus, while adjusting the clamping of the mattress sponge, the spraying range of the glue spraying cylinder 5 can be adapted to it, avoiding unnecessary waste during glue spraying.

[0036] By pressing down the square block 11 to drive the wedge block 12 to release the insertion with the square column 8, the L-shaped plate 18 can be pulled to drive the square plate 9 to move outward. After the adjustment is completed, the machine is started. The mattress sponge slides forward through the pulley 10 on the square plate 9 by the conveyor 2 for uniform glue spraying. After the spraying is completed, another sponge mattress on the frame 3 is pulled, and they are squeezed and bonded together through the pressure roller 14. Pressing down to release the fixation is convenient and fast while improving work efficiency.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
