[0030] For further information, please refer to Figure 11-17 A rotating mechanism 200 is sleeved on the surface of the sampler 100, and a plurality of quick filling mechanisms 300 are fixedly connected to the surface of the rotating mechanism 200.
[0031] Furthermore, the rotating mechanism 200 includes a rotating ring 201, which is movably mounted on the surface of the shell 101. The bottom of the rotating ring 201 is rotatably connected to a magnetic seat 203, which is fixedly mounted on the surface of the shell 101. A plurality of magnetic parts 204 are installed inside the magnetic seat 203, and the magnetic parts 204 are magnetically connected to the rotating ring 201. A plurality of anti-slip protrusions 205 are provided on the top of the surface of the rotating ring 201, and a connecting arm 202 is fixedly connected to the surface of the rotating ring 201.
[0032] Furthermore, the swivel 201 is made of iron metal material.
[0033] Furthermore, the quick filling mechanism 300 includes a filling tube 301, a fixed arm 302 is fixedly connected to the surface of the filling tube 301, the fixed arm 302 is fixedly connected to the connecting arm 202, the filling tube 301 is located at the top of the storage tube 103, the bottom of the filling tube 301 is aligned with the top of the storage tube 103, a threaded cover 305 is provided on the top threaded sleeve of the filling tube 301, a discharge assembly 303 is fixedly connected to the bottom of the filling tube 301, a positioning assembly 304 is fixedly connected to the bottom of the surface of the filling tube 301, and a pushing assembly 306 is movably connected inside the filling tube 301.
[0034] Furthermore, the discharging assembly 303 includes a fixing ring 3031, which is fixedly installed at the bottom of the filling tube 301, and a rubber ring 3032 is fixedly connected to the inner wall of the fixing ring 3031. A plurality of rubber sheets 3033 are arranged inside the rubber ring 3032, and a petal groove 3034 is arranged on the opposite side of the rubber sheet 3033.
[0035] Furthermore, the positioning assembly 304 includes a sliding seat 3041, which is fixedly installed on the bottom of the surface of the fixing ring 3031, and the top of the inner cavity of the sliding seat 3041 is fixedly connected with a positioning pin 3042, and the surface of the positioning pin 3042 is movably sleeved with a spring 3043, and the bottom of the spring 3043 is fixedly connected with a fixing piece 3044, and the bottom of the fixing piece 3044 is fixedly connected with a stop pin 3045, and the stop pin 3045 is slidably connected to the bottom of the sliding seat 3041, and the surface of the stop pin 3045 is movably connected to the surface of the storage tube 103.
[0036] Furthermore, the pushing assembly 306 includes a pushing cylinder 3061, the surface of which is movably connected to the inner wall of the storage tube 103, a rounded corner 3063 is provided at the bottom of the pushing cylinder 3061, a pushing handle 3062 is fixedly connected to the surface of the pushing cylinder 3061, a sliding cavity 307 for use with the pushing handle 3062 is provided on the surface of the filling tube 301, a damping ring 3064 is fixedly connected to the surface of the pushing handle 3062, and the damping ring 3064 is movably sleeved on the surface of the filling tube 301.
[0037] When the adhesive dispenser 104 needs to be replenished, the rotating mechanism 200 is first assembled, the rotating ring 201 is placed on the surface of the storage tube 103, and is placed on the magnetic seat 203. The magnetic part 204 inside the magnetic seat 203 magnetically attracts the rotating ring 201, so that the rotating ring 201 can be adsorbed on the magnetic seat 203 and rotate on the top of the magnetic seat 203. The rotating ring 201 drives several quick filling mechanisms 300 to rotate simultaneously through the connecting arm 202 to replenish the adhesive dispenser 104.
[0038] The inside of the filling tube 301 of the quick filling mechanism 300 is filled with a number of sticking devices 104 in advance, and then the pushing assembly 306 is installed on the top of the inner cavity of the filling tube 301, and the threaded cover 305 is screwed on the top of the filling tube 301 to limit the top of the pushing assembly 306. When the filling tube 301 moves to the top of the storage tube 103, the positioning assembly 304 contacts the surface of the storage tube 103 to limit the filling tube 301 so that the filling tube 301 and the storage tube 103 can be aligned, and the pushing assembly 306 is moved inside the sliding cavity 307 and the filling tube 301. The pushing assembly 306 drives the several sticking devices 104 to move downward, and the sticking devices 104 pass through the discharge assembly 303 and enter into the storage tube 103 to quickly fill the inside of the storage tube 103.
[0039] When the positioning assembly 304 is limiting, the surface of the stop pin 3045 contacts the surface of the storage tube 103 to prevent the filling tube 301 from excessive rotation. When the filling is completed and the storage tube 103 needs to be rotated further, the stop pin 3045 is moved upward. The stop pin 3045 compresses the spring 3043 through the fixing part 3044, and the positioning pin 3042 limits the top of the spring 3043. When the stop pin 3045 retracts to the inside of the sliding seat 3041, it is away from the surface of the storage tube 103, so that the filling tube 301 can continue to rotate.
[0040] During the operation of the pushing assembly 306, the pushing cylinder 3061 is moved downward by the pushing handle 3062, the pushing handle 3062 slides inside the sliding cavity 307, and the damping ring 3064 slides on the surface of the filling tube 301, thereby increasing the damping of the pushing cylinder 3061 during its movement, so that the feeding can be stable. The rounded corner 3063 at the bottom of the pushing cylinder 3061 contacts the top of the sticking device 104 to drive several sticking devices 104 to move downward. By setting the rounded corner 3063, it is easy to insert the pushing cylinder 3061 into the storage tube 103.
[0041] During the operation of the discharge component 303, the fixing ring 3031 fixes the rubber ring 3032, the adhesive seat 1043 first passes through the rubber sheet 3033, and then the elastic body 1041 passes through the rubber sheet 3033. When the adhesive 104 passes through the rubber sheet 3033, several rubber sheets 3033 are deformed outward, so that several petal grooves 3034 are connected, and a discharge channel is formed inside the rubber ring 3032. The adhesive 104 enters the storage tube 103 through the discharge channel. When the entry is completed, the rubber sheet 3033 automatically resets to seal the inside of the rubber ring 3032 to prevent the adhesive 104 from passing through the discharge component 303 and falling.
