[0035] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0036] like Figure 1 and 2 As shown, a rapid glue filling mechanism provided by the present invention includes a glue filling component and a glue feeding component, and the glue filling component and the glue feeding component are plugged into each other; the glue filling component includes a telescopic rod 4, a glue filling head 10 and a glue filling block 8 which are sequentially sleeved from the inside to the outside; the glue feeding component includes a limiting rod 12, a sliding ring 13 and a glue feeding block 17 which are sequentially sleeved from the inside to the outside, and the side of the limiting rod 12 away from the glue filling component is fastened to the glue feeding block 17; the side of the limiting rod 12 close to the glue filling component is snap-fitted with the sliding ring 13, and the side of the glue feeding block 17 close to the glue filling component is sealed; the glue filling head 10 It is plugged into the glue feeding block 17, the glue filling head 10 is transmission-connected to the sliding ring 13, and the limit rod 12 is transmission-connected to the telescopic rod 4; a first glue filling channel is provided inside the glue filling block 8, and a second glue filling channel is provided inside the glue filling head 10, and the output end of the first glue filling channel is connected to the input end of the second glue filling channel; a third glue filling channel is provided inside the glue feeding block 17, and the third glue filling channel is respectively connected to the glue filling head glue outlet 19 of the second glue filling channel and the external environment; the glue filling head glue outlet 19 is provided on the inner side of the glue filling head 10, and the telescopic rod 4 can seal the glue filling head glue outlet 19.

[0037] In the unfilled state, the glue filling assembly and the glue inlet assembly are each sealed to ensure the cleanliness of their respective filling environments. When filling is required, the glue filling assembly is inserted into the glue inlet assembly, connecting the glue channels. The glue channels are tightly sealed to prevent overflow, achieving efficient glue filling. During glue filling, the glue filling channels automatically connect, and after filling is complete, the channels automatically disconnect and isolate the air, allowing for recycling. The device is easy to maintain and use, and has strong applicability.

[0038] like Figure 3-5 As shown, the input end of the first glue filling channel is provided with a glue inlet 18, and the glue inlet 18 is connected to the external environment. Generally, the glue inlet 18 is connected to the glue filling pipeline, and the control valve opens the glue filling pipeline, and the glue enters the first glue filling channel from the glue filling pipeline through the glue inlet. The output end of the third glue filling channel is provided with a plurality of openings, and the plurality of openings are evenly distributed along the circumference of the limit rod 12 to ensure the uniformity of the glue filling and effectively improve the efficiency of the glue filling. Generally, the glue feed block 17 is inserted into the circulating rubber hose, and the output end of the third glue filling channel is connected to the glue feed channel of the circulating rubber hose. The glue enters the glue storage space of the circulating rubber hose from the third glue filling channel through the glue feed channel of the circulating rubber hose.

[0039] A protrusion is provided on the side of the sliding ring 13 away from the glue filling assembly. A second flood seal 14 is provided between the protrusion and the limiting rod 12. A third flood seal 15 is provided between the protrusion and the glue feeding block 17.

[0040] In the unfilled state, the glue filling assembly has its glue inlet 18 closed, and the glue outlet 19 is located inside the glue filling head 10. The telescopic rod 4 seals the glue outlet 19, thereby closing the first and second glue filling channels. In the glue feeding assembly, the sliding ring 13 and the limiting rod 12 are each provided with matching stepped grooves and protrusions. The limiting rod 12 engages with the sliding ring 13 on the side closest to the glue filling assembly, and the sealing glue feeding block 17 is located on the side closest to the glue filling assembly.

[0041] A second spring 16 is sleeved on the limiting rod 12 , and two ends of the second spring 16 are respectively tightly fitted with the glue feeding block 17 and the sliding ring 13 .

[0042] like Figure 6 As shown, a driving mechanism is provided at the bottom of the glue filling assembly, which includes a quick clamp 1, a slider guide 2 and a transition block 3. The bottom of the transition block 3 slides with the slider guide 2; the top of the transition block 3 is fastened to the bottom of the glue filling block 8; the quick clamp 1 and the transition block 3 are transmission-connected.

[0043] A locking nut 5 is provided at one end of the glue filling block 8 away from the glue feeding assembly. The locking nut 5 is sleeved on the telescopic rod 4. A first spring 7 is provided between the locking nut 5 and the telescopic rod 4.

[0044] During glue filling, manually tighten the quick-action clamp 1, causing the glue filling block 8 and transition block 3 to move smoothly to the right on the slider guide 2, allowing the glue filling assembly to be inserted into the glue feed assembly. The insertion end of the glue filling head 10 is inserted into the glue feed block 17. The glue filling head 10 presses against the sliding ring 13 and moves to the right. The sliding ring 13 begins to compress the first spring 16. The second flood seal 14 cooperates with the limit rod 12 to form the glue feed block glue inlet 20, and the third glue filling channel is now open.

[0045] When the filling assembly is inserted into the glue feed assembly, the limit rod 12 remains stationary, pressing against the telescopic rod 4. As the filling head 10 moves rightward, the telescopic rod 4 compresses the first spring 7, causing relative movement of the telescopic rod 4 to the left. At this point, the filling head's glue outlet 19 opens, connecting the second and third glue channels. The glue feed 18 then opens, allowing the glue to flow through the first and second glue channels, then through the filling head's glue outlet 19 into the third glue channel. The glue then passes through the glue feed block's glue inlet 20 and is discharged from the output end of the third glue channel.

[0046] After the glue filling is completed, the glue filling assembly is pulled back, and the second spring 16 in the glue feeding assembly presses the sliding ring 13 to move to the left. The limiting rod 12 is engaged with the sliding ring 13 and seals the glue feeding block 17. The second pan seal 14, the limiting rod 12 and the sliding ring 13 cooperate to achieve the sealing of the mating surface between the limiting rod 12 and the sliding ring 13. The third pan seal 15, the sliding ring 13 and the glue feeding block 17 cooperate to achieve the sealing of the mating surface between the sliding ring 13 and the glue feeding block 17. At this time, the third glue filling channel is closed and sealed.

[0047] In the glue filling assembly, the glue filling head 10 exits the glue inlet block 17, and the first spring 7 pushes the telescopic rod 4 to the right. The telescopic rod 4 and the glue filling head 10 form a seal, preventing glue from escaping from the glue filling head outlet 19. A first flood seal 6 is installed between the locking nut 5, the glue filling block 8, and the glue filling head 10. The locking nut 5 tightens the first flood seal 6, preventing glue from escaping from the left end of the glue filling block 8.

[0048] Furthermore, a first sealing ring 9 is installed on the outside of the connection between the output end of the first glue filling channel and the input end of the second glue filling channel. The glue filling block 8, first sealing ring 9, and glue filling head 10 work together to prevent glue from overflowing from the mating surface between the glue filling block 8 and the glue filling head 10. A second sealing ring 11 is installed around the insertion end of the glue filling head 10. This second sealing ring 11 prevents glue from overflowing when the glue filling head 10 and the glue feed block 17 are pressed together.

[0049] The present invention utilizes a structure in which the filling head 10 extends into the glue feed block 17, enabling automatic opening during filling and automatic sealing during exit, achieving efficient filling. The use of a first flood seal 6, a second flood seal 14, a third flood seal 15, a first sealing ring 9, and a second sealing ring 11 ensures the sealing of the entire structure. The output end of the present invention is connected to a hose, disconnecting the glue from the hose, allowing the hose to be recycled in the next stage, effectively saving costs and further improving filling efficiency.

[0050] How it works

[0051] During glue filling, manually tighten the quick-action clamp 1, causing the glue filling block 8 and transition block 3 to move smoothly to the right on the slider guide 2, allowing the glue filling assembly to be inserted into the glue feed assembly. The insertion end of the glue filling head 10 is inserted into the glue feed block 17. The glue filling head 10 presses against the sliding ring 13 and moves to the right. The sliding ring 13 begins to compress the first spring 16. The second flood seal 14 cooperates with the limit rod 12 to form the glue feed block inlet 20, and the third glue filling channel is now open. When the glue filling assembly is inserted into the glue feed assembly, the limit rod 12 remains stationary and presses against the telescopic rod 4. During the entire rightward movement of the glue filling head 10, the telescopic rod 4 compresses the first spring 7, causing relative movement of the telescopic rod 4 to the left. At this time, the glue filling head outlet 19 opens, and the second glue filling channel is connected to the third glue filling channel. Then, the glue inlet 18 is opened, and the glue flows from the inlet 18 into the first glue filling channel, then into the second glue filling channel, and then from the glue filling head outlet 19 into the third glue filling channel. The glue flows through the glue feed block inlet 20 and is discharged from the output end of the third glue filling channel. After glue filling is completed, the glue filling assembly is retracted, and the second spring 16 in the glue feed assembly presses the sliding ring 13 to move leftward. The limit rod 12 engages with the sliding ring 13 and seals the glue feed block 17. The second flood seal 14, the limit rod 12, and the sliding ring 13 cooperate to seal the mating surface between the limit rod 12 and the sliding ring 13. The third flood seal 15, the sliding ring 13, and the glue feed block 17 cooperate to seal the mating surface between the sliding ring 13 and the glue feed block 17. The third glue filling channel is now closed and sealed. In the glue filling assembly, the glue filling head 10 exits the glue inlet block 17, and the first spring 7 pushes the telescopic rod 4 to the right. The telescopic rod 4 and the glue filling head 10 form a seal, preventing glue from overflowing from the glue filling head outlet 19. The locking nut 5 tightens the first flood seal 6, preventing glue from overflowing from the left end of the glue filling block 8.
