It is widely used in the fields of construction, automobiles, electronic equipment, etc. It can prevent liquid leakage, block the entry of oxygen, moisture, and odor, and has the function of preventing counterfeiting and inferior products. There are many types of sealants, which can be classified into different categories according to the vulcanization method, form, and performance after construction.

[0003] There is a device with publication number CN114682450A, entitled "extrusion device for sealant for toothpaste bags", comprising a machine base, wherein two extrusion rollers are installed in parallel and at intervals in the machine base, wherein the gap between the two extrusion rollers is used to accommodate the rear end of the toothpaste bag to extend therein, wherein a through groove is formed in the machine base, wherein a guide rod is slidably installed in the through groove, wherein the guide rod extends from the front end surface of the machine base, wherein the front end of the guide rod can be connected and fixed to the front end of the toothpaste bag, wherein a clamping mechanism is installed in the rear end surface of the machine base, wherein the clamping mechanism is formed with a jaw portion, wherein the jaw portion is used to clamp and fix the rear end of the toothpaste bag, wherein the clamping mechanism is formed integrally with the end surface on the same side of the machine base and the rear end of the guide rod, wherein a pull handle is installed in the end surface opposite to the clamping mechanism and the machine base.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Example 1, reference Figure 1-4 A sealant extrusion device includes a cylinder assembly 1 and a glue holding tube 3, and the glue holding tube 3 is connected to the cylinder assembly 1 through a connecting frame 2, and the other side of the glue holding tube 3 is connected to an extrusion tube 5, and a through hole 23 is opened on the inner side of the extrusion tube 5, and a straight tube 21 is connected at the position of the through hole 23.

[0035] An anti-blocking component is arranged between the inner side and the bottom of the straight tube 21, and the anti-blocking component includes a cross beam 13, a return spring 14, a sphere 15, a junction box 16, a jitter suppression component 17 and an extrusion port 18. The junction box 16 is connected to the bottom of the straight tube 21, and the extrusion port 18 is located at the bottom of the junction box 16. The cross beam 13 is horizontally arranged at the upper end of the straight tube 21, the sphere 15 slides in the straight tube 21, and the return spring 14 is connected between the sphere 15 and the cross beam 13. The inner diameter of the junction box 16 is larger than the diameter of the straight tube 21, and the outer surface of the sphere 15 and the inner surface of the straight tube 21 are in contact with each other.

[0036] The glue holding cylinder 3 contains glue. Under the squeezing of the piston plate inside the glue holding cylinder 3 by the cylinder assembly 1, the pressure inside the glue holding cylinder 3 increases, and the glue enters the extrusion tube 5 from one end. As the pressure is transmitted to the inside of the extrusion tube 5, the movable frame 9 inside the extrusion tube 5 will be pushed to move to the side away from the glue holding cylinder 3. At this time, the position of the movable frame 9 and the through hole 23 at the lower end do not coincide, and the glue enters the straight tube 21 along the through hole 23. The ball 15 moves downward under pressure until the ball 15 moves into the junction box 16. At this time, a gap appears between the straight tube 21 and the ball 15, and the glue can effectively pass through the junction box 16 and the extrusion port 18 at the lower end along the gap to achieve glue extrusion. When the glue is squeezed out, the cylinder assembly 1 drives the piston plate inside the glue holding cylinder 3 to return to its initial position. At this time, the glue holding cylinder 3 is pressed down and the glue is pushed back to the original position. The air pressure inside the tube 3 decreases, and the air inside the second chamber 11 recovers to a balanced state due to the original squeezed state. At this time, the atmospheric pressure in the second chamber 11 will push the movable frame 9 to cover the through hole 23 at the lower end again. In this way, after the glue extrusion work is completed, the sphere 15 and the movable frame 9 form a double-layer barrier to isolate the glue tube 3 from the external air. The purpose of this is: once air is mixed into the glue tube 3, the glue will deteriorate. Secondly, when the movable frame 9 covers the upper end of the through hole 23, the original reset spring 14 is in a stretched state, and the reset spring 14 will pull the sphere 15 to move upward. During the movement, the sphere 15 contacts the inner wall of the straight tube 21. During the contact, the glue adhering to the inner wall of the straight tube 21 is squeezed into the storage box 12.

[0037] Example 2, reference Figure 6 The difference between this embodiment and embodiment 1 is that a jitter suppression component 17 is arranged between the sphere 15 and the junction box 16, and when the sphere 15 enters the junction box 16, the glue in the straight tube 21 flows into the junction box 16, and the jitter suppression component 17 includes a first magnet sheet 171, a second magnet sheet 172, a slot 173 and a bracket 174.

[0038] The first magnet piece 171 is fixedly mounted on the lower end of the sphere 15, the bracket 174 is arranged in an arc shape on the inner side of the junction box 16, the slot 173 is opened in the middle position of the upper end of the bracket 174, and the second magnet piece 172 is clamped in the slot 173. When the sphere 15 enters the inner side of the junction box 16, the first magnet piece 171 and the second magnet piece 172 are adsorbed together.

[0039] When the sphere 15 moves downward on the inner side of the straight tube 21, the glue flowing down from the upper end continuously contacts the sphere 15, which will cause the sphere 15 to shake in the vertical direction. When the sphere 15 shakes, the amount of glue extruded will fluctuate, resulting in uneven extrusion.

[0040] To this end, a bracket 174 is provided on the inner side of the junction box 16, and the first magnet sheet 171 and the second magnet sheet 172 are adsorbed between the bracket 174 and the lower end of the sphere 15 to fix the position of the sphere 15. At this time, the gravity of the sphere 15 itself, the pulling force of the return spring 14, the pressure in the straight tube 21 and the suction force of the magnet during adsorption, multiple forces reach a balanced state, and the sphere 15 is in a balanced state. At the same time, when the extrusion work is completed, after the pressure acting on the upper end of the sphere 15 is removed, the sphere 15 is driven to move upward under the action of the return spring 14, and the first magnet sheet 171 and the second magnet sheet 172 are separated from each other.

[0041] Example 3, reference Figure 1-3 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a movable frame 9 is slidably provided on the inner side of the extrusion tube 5, and the movable frame 9 divides the interior of the extrusion tube 5 into two independent and closed spaces, namely a first chamber 10 and a second chamber 11. When the position of the movable frame 9 coincides with the position of the through hole 23, the movable frame 9 will block the through hole 23. A liquid leakage component is provided on the side of the movable frame 9 close to the glue holding cylinder 3, and the liquid leakage component is connected to the drug injection tube 4, and the drug injection tube 4 is installed on the extrusion tube 5.

[0042] refer to Figure 7 The leakage component includes an inner sleeve 8, an outer sleeve 6, a first overflow hole 7 and a second overflow hole 22. One end of the inner sleeve 8 is fixedly mounted on the movable frame 9. The outer sleeve 6 is sleeved on the outside of the inner sleeve 8, and the outer surface of the inner sleeve 8 and the inner surface of the outer sleeve 6 are in contact with each other. The medicine injection tube 4 is connected to one end of the outer sleeve 6. The first overflow hole 7 is provided at the end of the outer sleeve 6. The second overflow holes 22 are distributed in a circular array at one end of the inner sleeve 8. When the first overflow hole 7 and the second overflow hole 22 coincide with each other, the medicine inside the outer sleeve 6 and the inner sleeve 8 overflows.

[0043] Since the sealant contains multiple ingredients, a large number of bubbles will be generated during the process of squeezing the glue. After the glue is squeezed out, when the bubbles inside it burst, the extrusion amount will be affected.

[0044] To this end, a defoaming agent is injected into the inner side of the drug injection tube 4. When the glue extrusion is in progress, the movable frame 9 moves to one side of the extrusion tube 5. At this time, the movable frame 9 will drive the inner sleeve 8 to move horizontally inside the outer sleeve 6. A relative displacement occurs between the inner sleeve 8 and the outer sleeve 6. The original state in which the first overflow hole 7 and the second overflow hole 22 do not overlap with each other will cause the first overflow hole 7 and the second overflow hole 22 to overlap with each other as the inner sleeve 8 moves. Then the defoaming agent will pass through the first overflow hole 7 and the second overflow hole 22 and overlap with the glue. The reason for this arrangement is that the glue has poor fluidity during the extrusion process, which will make the defoaming agent unable to be fully mixed in the glue and contact with the bubbles in the glue. On the other hand, the addition of the defoaming agent occurs and ends simultaneously with the extrusion of the glue, which ensures sufficient mixing while effectively controlling the amount of defoaming agent added.

[0045] Example 4, reference Figure 5 The difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that there are several groups of control components 20 evenly arranged on the upper part of the straight tube 21, and the control components 20 are connected to the storage box 12. The control components 20 include a connecting hole 201, a rotating shaft 202, an elastic column 203 and a flap 204. The connecting hole 201 is opened on one side of the straight tube 21, the rotating shaft 202 is located at the inner upper part of the connecting hole 201, the flap 204 is sleeved outside the rotating shaft 202, and when the flap 204 is in a vertical state, the flap 204 and the connecting hole 201 match each other, and the elastic column 203 is connected between the flap 204 and the lower end of the connecting hole 201.

[0046] The upper port of the storage box 12 coincides with the connection hole 201, and the port of the storage box 12 covers the connection hole 201. The lower end of the storage box 12 is threadedly connected with a glass stopper 19, and the inside of the storage box 12 contains a mixture of soap solution, ammonia water and turpentine.

[0047] Since the upper through hole 23 is blocked by the movable frame 9, during the upward movement of the sphere 15, the sphere 15 will compress the air at the upper end of the straight tube 21, further increasing the air pressure in the upper end portion of the straight tube 21 between the movable frame 9 and the sphere 15. The increased air pressure will push the flap 204 at the upper end of the straight tube 21 to an inclined position. At this time, the glue in the straight tube 21 will pass through the gap between the flap 204 and the connecting hole 201 and enter the storage box 12 for collection. After squeezing the glue remaining on the inner wall of the straight tube 21 into the interior of the storage box 12, a mixture of soap solution, ammonia water and turpentine is injected into the interior of the storage box 12 in advance. The three liquids are mixed in a ratio of 1:1:1. The mixture can effectively prevent the glue from adhering to the inner wall of the storage box 12. The bottom of the storage box 12 is threadedly connected with a glass stopper 19. Afterwards, the glass stopper 19 is unscrewed and the glue mixture inside the storage box 12 can be poured out.

[0048] It should be noted that: when the sphere 15 descends, since the cross-sectional size of the straight tube 21 is larger than the cross-sectional size of the storage box 12, the glue will preferentially enter the straight tube 21. The larger cross-sectional area can provide a larger space to accommodate the liquid. According to the flow principle of the liquid, the liquid will naturally flow to a path with less resistance in the absence of external pressure. The straight tube 21 usually has less resistance due to its larger cross-sectional area, so the liquid will preferentially flow into the straight tube 21.

[0049] The working principle of the device is:

[0050] The glue holding cylinder 3 contains glue. Under the squeezing of the piston plate inside the glue holding cylinder 3 by the cylinder assembly 1, the pressure inside the glue holding cylinder 3 increases, and the glue enters the extrusion tube 5 from one end. As the pressure is transmitted to the inside of the extrusion tube 5, the movable frame 9 inside the extrusion tube 5 will be pushed to move to the side away from the glue holding cylinder 3. At this time, the position of the movable frame 9 and the through hole 23 at the lower end do not coincide, and the glue enters the straight tube 21 along the through hole 23. The ball 15 moves downward under pressure until the ball 15 moves into the junction box 16. At this time, a gap appears between the straight tube 21 and the ball 15, and the glue can effectively pass through the junction box 16 and the extrusion port 18 at the lower end along the gap to achieve glue extrusion. When the glue is squeezed out, the cylinder assembly 1 drives the piston plate inside the glue holding cylinder 3 to return to its initial position. At this time, the glue holding cylinder 3 is pressed down and the glue is pushed back to the original position. The air pressure inside the tube 3 decreases, and the air inside the second chamber 11 recovers to a balanced state due to the original squeezed state. At this time, the atmospheric pressure in the second chamber 11 will push the movable frame 9 to cover the through hole 23 at the lower end again. In this way, after the glue extrusion work is completed, the sphere 15 and the movable frame 9 form a double-layer barrier to isolate the glue tube 3 from the external air. The purpose of this is: once air is mixed into the glue tube 3, the glue will deteriorate. Secondly, when the movable frame 9 covers the upper end of the through hole 23, the original reset spring 14 is in a stretched state, and the reset spring 14 will pull the sphere 15 to move upward. During the movement, the sphere 15 contacts the inner wall of the straight tube 21. During the contact, the glue adhering to the inner wall of the straight tube 21 is squeezed into the storage box 12.

[0051] Since the upper through hole 23 is blocked by the movable frame 9, during the upward movement of the sphere 15, the sphere 15 will compress the air at the upper end of the straight tube 21, further increasing the air pressure in the upper end portion of the straight tube 21 between the movable frame 9 and the sphere 15. The increased air pressure will push the flap 204 at the upper end of the straight tube 21 to an inclined position. At this time, the glue in the straight tube 21 will pass through the gap between the flap 204 and the connecting hole 201 and enter the storage box 12 for collection. After squeezing the glue remaining on the inner wall of the straight tube 21 into the interior of the storage box 12, a mixture of soap solution, ammonia water and turpentine is injected into the interior of the storage box 12 in advance. The three liquids are mixed in a ratio of 1:1:1. The mixture can effectively prevent the glue from adhering to the inner wall of the storage box 12. The bottom of the storage box 12 is threadedly connected with a glass stopper 19. Afterwards, the glass stopper 19 is unscrewed and the glue mixture inside the storage box 12 can be poured out.

[0052] It should be noted that: when the sphere 15 descends, since the cross-sectional size of the straight tube 21 is larger than the cross-sectional size of the storage box 12, the glue will preferentially enter the straight tube 21. The larger cross-sectional area can provide a larger space to accommodate the liquid. According to the flow principle of the liquid, the liquid will naturally flow to a path with less resistance in the absence of external pressure. The straight tube 21 usually has less resistance due to its larger cross-sectional area, so the liquid will preferentially flow into the straight tube 21.

[0053] When the sphere 15 moves downward on the inner side of the straight tube 21, the glue flowing down from the upper end continuously contacts the sphere 15, which will cause the sphere 15 to shake in the vertical direction. When the sphere 15 shakes, the amount of glue extruded will fluctuate, resulting in uneven extrusion.

[0054] To this end, a bracket 174 is provided on the inner side of the junction box 16, and the first magnet sheet 171 and the second magnet sheet 172 are adsorbed between the bracket 174 and the lower end of the sphere 15 to fix the position of the sphere 15. At this time, the gravity of the sphere 15 itself, the pulling force of the return spring 14, the pressure in the straight tube 21 and the suction force of the magnet during adsorption, multiple forces reach a balanced state, and the sphere 15 is in a balanced state. At the same time, when the extrusion work is completed, after the pressure acting on the upper end of the sphere 15 is removed, the sphere 15 is driven to move upward under the action of the return spring 14, and the first magnet sheet 171 and the second magnet sheet 172 are separated from each other.

[0055] Since the sealant contains multiple ingredients, a large number of bubbles will be generated during the process of squeezing the glue. After the glue is squeezed out, when the bubbles inside it burst, the extrusion amount will be affected.

[0056] To this end, a defoaming agent is injected into the inner side of the drug injection tube 4. When the glue extrusion is in progress, the movable frame 9 moves to one side of the extrusion tube 5. At this time, the movable frame 9 will drive the inner sleeve 8 to move horizontally inside the outer sleeve 6. A relative displacement occurs between the inner sleeve 8 and the outer sleeve 6. The original state in which the first overflow hole 7 and the second overflow hole 22 do not overlap with each other will cause the first overflow hole 7 and the second overflow hole 22 to overlap with each other as the inner sleeve 8 moves. Then the defoaming agent will pass through the first overflow hole 7 and the second overflow hole 22 and overlap with the glue. The reason for this arrangement is that the glue has poor fluidity during the extrusion process, which will make the defoaming agent unable to be fully mixed in the glue and contact with the bubbles in the glue. On the other hand, the addition of the defoaming agent occurs and ends simultaneously with the extrusion of the glue, which ensures sufficient mixing while effectively controlling the amount of defoaming agent added.
