A round hole 5-2 is provided on the top of the hose 4. A sleeve 5-3 is connected to the output end of the telescopic cylinder 5-1. A plurality of long holes 5-4 are provided on the outer surface of the sleeve 5-3. A screw 5-5 is fixedly connected to the top of the sleeve 5-3. The screw 5-5 is screwed with an internal thread block 5-6. An extrusion rod 5-7 is movably sleeved in the sleeve 5-3. An extrusion plate 5-8 is fixedly connected to the lower end of the extrusion rod 5-7. A plurality of limit blocks 5-9 are provided on the upper end of the extrusion rod 5-7. The limit blocks 5-9 are located in the long holes 5-4. A support spring 5-10 is sleeved on the outside of the extrusion rod 5-7. A long groove 5-11 is provided on the upper end of the extrusion rod 5-7. A connecting pipe 5-12 is connected between the rubber hose 4 and the glue tank 2, and a control valve 5-13 is installed on the connecting pipe 5-12. A reinforcing rod 5-14 is fixedly connected between the fixing rods 3, and the reinforcing rod 5-14 is sleeved on the outside of the connecting pipe 5-12. A pair of vertical plates 5-15 are fixedly connected to the bottom of the fixing plate 1, and a second cylinder 5-16 is fixedly connected to the surface of the vertical plate 5-15. A connecting block is provided at the output end of the second cylinder 5-16. 5-17, a pair of grooves 5-18 are provided on the side end face of the connecting block 5-17, a round rod 5-19 is fixed in the groove 5-18, a sealing block 5-20 is movably mounted on the outside of the round rod 5-19, a booster spring 5-21 is mounted on the outside of the round rod 5-19, the sealing block 5-20 is fitted on the lower opening of the rubber hose 4, an extrusion cylinder 5-22 is installed on the bottom of the glue tank 2, and a sealed glue inlet 5-23 is provided on the top of the glue tank 2.

[0030] In this embodiment, in order to achieve the effect of quantitative glue discharge from the hose 4, a quantitative extrusion assembly 5 is designed. Two telescopic cylinders 5-1 are fixed on the surface of the fixed plate. A long hole 5-4 is opened on the top of the hose 4. A sleeve 5-3 is connected to the output end of the telescopic cylinder 5-1. The sleeve 5-3 passes through the circular hole 5-2 and is located in the hose 4. The surface of the sleeve 5-3 is provided with a long hole 5-4. The inner sleeve 5-3 of the sleeve 5-3 has a telescopic extrusion rod 5-7. The lower end of the extrusion rod 5-7 is provided with an extrusion plate 5-8. The extrusion plate 5-8 is used to The rubber is extruded, and a supporting spring 5-10 is also mounted on the extrusion rod 5-7. A connecting pipe 5-12 is connected between the rubber hose 4 and the rubber tank 2. An extrusion cylinder 5-22 is arranged at the bottom of the rubber tank 2. The extrusion cylinder 5-22 can squeeze the rubber in the rubber tank 2 into the rubber hose 4. When the rubber enters the rubber hose 4, it pushes the extrusion plate 5-8 upward. The amount of the rubber entering is the amount of the rubber injection extrusion. A long groove 5-11 is provided at the upper end of the extrusion rod 5-7. A screw 5-5 is fixed at the top of the sleeve 5-3. The lower end of the screw 5-5 is located in the long groove 5-11. The screw The rod 5-5 is screwed with an internal thread block 5-6, which can move up and down on the surface of the screw rod 5-5. The height of the internal thread block 5-6 on the surface of the screw rod 5-5 determines the distance that the extrusion rod 5-7 can move upward. When the amount of extrusion glue inlet and outlet needs to be increased, the internal thread block 5-6 is twisted to move upward. The higher the moving position, the longer the distance that the extrusion rod 5-7 contracts upward, and the larger the capacity inside the hose 4. Two vertical plates 5-15 are also fixed at the bottom of the fixed plate 1. The surface of the vertical plate 5-15 is designed A second cylinder 5-16 is arranged, and a connecting block 5-17 is connected to the output end of the second cylinder 5-16. A groove 5-18 is provided on the surface of the connecting block 5-17 and a round rod 5-19 is installed. A sealing block 5-20 is slidably sleeved on the round rod 5-19, and a booster spring 5-21 is sleeved on the round rod 5-19. The movement of the sealing block 5-20 can be controlled by the telescopic function of the second cylinder 5-16. The sealing block 5-20 can block the outlet of the glue tank 2 so that the glue will not overflow when it is fed in. When the glue is discharged, the sealing block 5-20 can be controlled to move away.

[0031] Furthermore, the upper right angle of the side end surface of the sealing block 5-20 is an inclined transition structure.

[0032] In this embodiment, through the inclined angle, when the sealing block 5-20 moves laterally, the inclined structural surface pushes the sealing block 5-20 downward, and cooperates with the elastic force of the booster spring 5-21 to make the sealing block 5-20 fit tightly to the outlet of the hose 4.

[0033] Furthermore, the inner diameter of the long groove 5-11 is larger than the diameter of the screw 5-5.

[0034] In this embodiment, due to the larger diameter of the long groove 5-11, the screw rod 5-5 will not be blocked when entering the interior of the long groove 5-11.

[0035] Furthermore, the outer surface of the internal thread block 5-6 is a frosted anti-slip structural surface.

[0036] In this embodiment, the anti-slip structure surface makes it easy for fingers to screw the internal thread block 5-6 through the long hole 5-4.

[0037] When glue injection is needed, according to the required glue output, the internal thread block 5-6 is twisted, and the internal thread block 5-6 moves on the surface of the screw 5-5. After adjusting to the height that matches the glue output, the extrusion cylinder 5-22 squeezes the glue in the glue tank 2 into the rubber hose 4 through the connecting pipe 5-12. After the glue enters, it pushes the extrusion plate 5-8 upward, and the extrusion rod 5-7 moves upward. After the upper end hits the bottom of the internal thread block 5-6 and can no longer continue to inject glue, it stops, and then closes the control valve 5-13, and then starts the second cylinder 5-16, pulls back the connecting block 5-17, separates the sealing block 5-20 from the opening of the rubber hose 4, and then starts the telescopic cylinder 5-1. The output end of the telescopic cylinder 5-1 pushes the sleeve 5-3 downward to apply force to the extrusion rod 5-7 and the extrusion plate 5-8 to squeeze out all the glue in the rubber hose 4.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
