[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4This utility model provides a pipe lining hose glue injection device, including a support frame 1, a guide pipe 4 sleeved on the support frame 1, a first control valve 7 at the upper part of the guide pipe 4, a hose 5 connected to the bottom of the guide pipe 4, a pipe opening protection component 6 above the support frame 1, the pipe opening protection component 6 including a support plate 61, a support plate 61 located on one side of the guide pipe 4 mounted on the top of the support frame 1, a rotating shaft 62 rotatably connected to one side of the support plate 61, a worm gear 63 fixedly mounted on one side of the rotating shaft 62, a turntable on the first control valve 7 connected to the rotating shaft 62 by a transmission component, a connecting rod 66 sleeved on the support frame 1, a turbine 67 at the top of the connecting rod 66 meshing with the worm gear 63, a protective seat 68 located below the hose 5 mounted at the bottom of the connecting rod 66, and a glue injection head at the bottom of the hose 5. The bottom of the nozzle protection component 6 is equipped with a protective seat 68, which allows the bottom of the hose 5 to be plugged when the device is not in use, preventing external dust from entering the hose 5 and affecting the quality of the glue dispensing. It also prevents the glue inside the hose 5 from solidifying upon contact with the outside environment. The nozzle protection component 6 is also provided on the first control valve 7. When the hose 5 needs to be used for glue dispensing, the turntable on the first control valve 7 is rotated, which drives the rotating shaft 62 to rotate via the transmission component. The rotation of the rotating shaft 62 drives the worm gear 63 to rotate. Since the worm gear 63 meshes with the turbine 67, it drives the connecting rod 66 to rotate, which in turn drives the protective seat 68 to rotate. This allows the bottom of the hose 5 to be opened for use when connecting the hose 5 and the guide pipe 4.

[0018] The transmission assembly includes pulleys 64 and a transmission belt 65. Pulleys 64 are fixedly fitted onto the outer sides of the turntable and the rotating shaft 62 on the first control valve 7, and the two pulleys 64 are connected by the transmission belt 65. The connection between the first control valve 7 and the rotating shaft 62 via pulleys 64 and the transmission belt 65 facilitates the rotation of the first control valve 7, which in turn drives the rotating shaft 62 to rotate, thereby controlling the position of the protective seat 68.

[0019] A screw cylinder 10 is fixedly sleeved on the support frame 1. The outer side of the connecting rod 66 is provided with an external thread 9, which is adapted to the screw cylinder 10. A square bar 13 is installed on the top of the connecting rod 66, and the outer side of the square bar 13 is movably sleeved in the inner cavity of the turbine 67. The bottom of the turbine 67 is rotatably connected to the top of the support frame 1. The connecting rod 66 is connected to the screw cylinder 10 through the external thread 9. When the connecting rod 66 rotates, it can drive the connecting rod 66 to move along the inner cavity of the screw cylinder 10, which makes it easy to remove the protective seat 68 from the bottom of the hose 5, so that the setting of the protective seat 68 does not affect the use of the hose 5.

[0020] The inner cavity of turbine 67 has a square cross-section, and the shape of the square bar 13 is adapted to the inner cavity of turbine 67. By adapting the shape of the square bar 13 to the inner cavity of turbine 67, the rotation of turbine 67 can drive the square bar 13 and connecting rod 66 to rotate, and the square bar 13 can move up and down inside turbine 67.

[0021] The support frame 1 has several evenly distributed guide tubes 4 on its top. The top of each guide tube 4 is connected to the bottom of a branch tube 3. The top of the branch tube 3 is connected to a connecting tube 2, and a second control valve 8 is installed on the connecting tube 2. By having several guide tubes 4 on the support frame 1, and each guide tube 4 having a first control valve 7, the efficiency of glue injection is improved, and it is also convenient to control the glue injection of a single guide tube 4.

[0022] A mounting plate 11 is installed on the rear side of the support frame 1, and mounting holes 12 are provided on the outer side of the mounting plate 11. The mounting plate 11 and mounting holes 12 on the rear side of the support frame 1 facilitate the installation of this device in a designated position for use.

[0023] Working principle: When using this device, the connecting pipe 2 is connected to the external glue. By controlling the second control valve 8, the connecting pipe 2 and the diverter pipe 3 are connected. The first control valve 7 is equipped with a pipe port protection component 6. When the hose 5 needs to be used for glue injection, the turntable on the first control valve 7 is rotated. The pulley 64 and the transmission belt 65 drive the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 drives the worm gear 63 to rotate. Since the worm gear 63 is engaged with the turbine 67, the connecting rod 66 is rotated, which in turn drives the protective seat 68 to rotate. When the hose 5 and the diverter pipe 4 are connected, the bottom of the hose 5 can be opened for use. The connecting rod 66 is connected to the screw barrel 10 through the external thread 9. When the connecting rod 66 rotates, it can move along the inner cavity of the screw barrel 10, which makes it easy to remove the protective seat 68 from the bottom of the hose 5, so that the setting of the protective seat 68 does not affect the use of the hose 5. The bottom of the nozzle protection component 6 is provided with a protective seat 68, which makes it easy to plug the bottom of the hose 5 when the device is not in use, so as to prevent external dust from entering the hose 5 and affecting the quality of dispensing.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
