They are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] This invention relates to a quick-release tool for adhesive pump throat seals, such as... Figure 1 and Figure 2As shown, it comprises a joint 3, an upper pressing rod 1 and a lower pressing rod 2, the upper pressing rod 1 comprises an upper contact part 102 and an upper connecting part 101, the lower pressing rod 2 comprises a lower contact part 202 and a lower connecting part 201, the upper pressing rod 1 is connected to the first end of the joint 3 through the upper connecting part 101, and the lower pressing rod 2 is detachably connected to the second end of the joint 3 through the lower connecting part 201. A hole 301 extending to the first end face of the joint 3 is arranged on the second end face of the joint 3, the hole 301 can be a blind hole, the lower connecting part 201 is provided with external threads, the hole 301 is correspondingly provided with internal threads, and the lower connecting part 201 is screwed to the second end of the joint 3, so that the lower pressing rod 2 is detachably connected to the joint 3 through threads. Preferably, the hole 301 can also be a through hole penetrating the joint 3, the axis of the through hole is perpendicular to the second end face of the joint 3, the upper connecting part 101 and the lower connecting part 201 are both provided with external threads, and correspondingly, internal threads are arranged at both ends of the through hole, the two internal threads can be discontinuous, or the through hole can be arranged as a threaded hole, so that the threads extend from the first end to the second end of the hole 301, and preferably, the joint 3 is a hexagonal nut. The upper connecting part 101 is screwed to the first end of the joint 3, and the lower connecting part 201 is screwed to the second end of the joint 3, so that the upper pressing rod 1 and the lower pressing rod 2 are both detachably connected to the joint 3 through threads, and by adjusting the depth of the threads screwed into the hole 301, the length of the upper pressing rod 1 and the lower pressing rod 2 extending into the joint 3 can be adjusted.

[0038] In order to improve the safety during operation, a strong magnet 4 can be arranged at the end of the lower contact part 202 of the lower pressing rod 2. When the tool is placed on the lower piston rod of the glue pump, the tool can be attracted to the lower piston rod to prevent falling. Preferably, the strong magnet 4 is detachably connected to the end of the lower contact part 202. A threaded hole penetrating the strong magnet 4 can be arranged in the middle of the strong magnet 4, and a corresponding threaded hole can be arranged in the middle of the contact part of the lower pressing rod 2, so that the strong magnet 4 is fixed to the lower pressing rod 2 by a countersunk screw 5. The end surface of the strong magnet 4 is slightly lower than the end surface of the strong magnet 4 after the countersunk screw 5 is screwed in, so that the end surface of the strong magnet 4 is flat and can be in full contact with the end surface of the lower piston rod. Preferably, the upper pressing rod 1 and the lower pressing rod 2 are cylindrical and are adapted to the upper piston rod and the lower piston rod. The strong magnet 4 is also cylindrical and has the same shape as the lower pressing rod 2. The diameter of the strong magnet 4 can be the same as or slightly smaller or larger than the diameter of the lower pressing rod 2. When the diameter of the strong magnet 4 is slightly smaller than the diameter of the lower pressing rod 2, a mounting groove is arranged at the end of the lower contact part 202, and the strong magnet 4 is embedded in the mounting groove, so that the end surface of the strong magnet 4 is flush with the end surface of the lower contact part 202. When the tool is placed on the lower piston rod of the glue pump, the strong magnet 4 and the lower contact part 202 are in contact with the end surface of the lower piston rod and are attracted to the lower piston rod, so that the tool placed on the lower piston rod will not fall. When the diameter of the strong magnet 4 is the same as or slightly larger than the diameter of the lower pressing rod 2, the strong magnet 4 is directly fixed to the end of the lower contact part 202. When the tool is placed on the lower piston rod of the glue pump, the strong magnet 4 is in contact with the end surface of the lower piston rod and is attracted to the lower piston rod, so that the tool placed on the lower piston rod will not fall.

[0039] In order to prevent the operator from being scratched and to facilitate assembly, the two ends of the upper pressing rod 1 and the lower pressing rod 2 can be chamfered, and preferably rounded. The upper pressing rod 1 further comprises an upper clamping part 103 fixedly connected to the upper contact part 102 and the upper connecting part 101 at both ends; the lower pressing rod 2 further comprises a lower clamping part 203 fixedly connected to the lower contact part 202 and the lower connecting part 201 at both ends; the upper clamping part 103 and the lower clamping part 203 facilitate clamping with a wrench or other tools. Preferably, the upper clamping part 103 and the lower clamping part 203 can be arranged as regular hexagons to facilitate clamping with a wrench. In order to reduce the weight of the tool and facilitate taking and placing, a blind hole extending from the upper connecting part 101 to the upper contact part 102 can be arranged on the upper pressing rod 1, and a blind hole extending from the lower connecting part 201 to the lower contact part 202 can be arranged on the lower pressing rod 2, so that the upper pressing rod 1 and the lower pressing rod 2 are arranged as hollow structures with relatively light weight.

[0040] The glue pump throat seal quick dismounting tool can be used to dismount and install the glue pump throat seal. The steps of dismounting the throat seal using the dismounting tool include:

[0041] a. Remove the coupling of the glue pump, ventilate, control the upper piston rod to move to the highest position, the lower piston rod to move to the lowest position, and separate the upper and lower ends of the glue pump piston rod, and then stop the air supply;

[0042] b. Remove the bolts of the fixed throat seal;

[0043] c. Place the throat seal disassembly tool on the lower piston rod of the glue pump, so that the end surface of the lower pressing rod 2 contacts the end surface of the lower piston rod;

[0044] d. Ventilate, and make the upper piston rod move downward to contact the end surface of the upper pressing rod 1;

[0045] e. The throat seal is moved upward by the internal pressure of the glue pump, and leaves the installation slot of the glue pump;

[0046] f. Stop the air supply, and remove the throat seal disassembly tool;

[0047] g. Remove the throat seal.

[0048] When the tool is used to disassemble the throat seal, the upper pressing rod 1, the joint 3 and the lower pressing rod 2 are used at the same time, the upper pressing rod 1 is screwed on the first end of the joint 3, and the lower pressing rod 2 is screwed on the second end of the joint 3, and the throat seal disassembly tool is assembled. When in use, the tool is placed on the lower piston rod of the glue pump, the end surface of the lower pressing rod 2 contacts the end surface of the lower piston rod, and the end surface of the upper pressing rod 1 contacts the end surface of the upper piston rod. When a strong magnet 4 is arranged at the end of the lower contact part 202 of the lower pressing rod 2, the tool can be attracted to the lower piston rod by the strong magnet 4, preventing it from falling off and improving the safety during operation. When separating the upper and lower ends of the glue pump piston rod, manual control is required, the upper piston rod is manually controlled to press the lower pressing rod 2 to the lowest position, and then the upper pressing rod 1 is moved to the highest position. When disassembling the bolts, in order to operate safely, the glue pump needs to be kept in a state of air stop to prevent the upper piston rod from moving downward due to accidental operation of the button. The throat seal disassembly tool is placed between the upper piston rod and the lower piston rod, the end surface of the upper pressing rod 1 contact part, the end surface of the lower pressing rod 2 contact part, the end surface of the strong magnet 4, and the end surface of the upper piston rod and the end surface of the lower piston rod are all smooth and flat, so the disassembly tool can be directly removed, or a wrench can be used to clamp the upper clamping part 103 and / or the lower clamping part 203 to further screw the upper pressing rod 1 and / or the lower pressing rod 2 into the joint 3, so that the length of the upper pressing rod 1 and / or the lower pressing rod 2 inserted into the joint 3 increases, thereby reducing the height of the disassembly tool, separating the disassembly tool from the upper piston rod, and making it easier to remove the disassembly tool.

[0049] After the throat seal is disassembled, cleaned, maintained and lubricated, it is reinstalled on the glue pump. The steps of installing the throat seal using the disassembly tool include:

[0050] a. Install the throat seal on the lower piston rod of the glue pump;

[0051] b, the dismounting tool is placed on the throat seal, the end surface of the second end of the joint 3 is in contact with the end surface of the throat seal;

[0052] c, air is supplied, the end surface of the upper piston rod is in contact with the end surface of the upper pressure rod 1;

[0053] d, the upper piston rod is lowered, the throat seal is pressed into the rubber pump installation groove;

[0054] e, the throat seal is completely pressed into the rubber pump installation groove, and the bolt for locking the throat seal is tightened;

[0055] f, air is cut off, the dismounting tool is removed, and the replacement of the throat seal is completed.

[0056] When the tool is used to install the throat seal, the upper pressure rod 1 and the joint 3 are used at the same time, the upper pressure rod 1 is screwed on the first end of the joint 3, or the lower pressure rod 2 of the throat seal dismounting tool is unscrewed, so that the upper pressure rod 1 and the joint 3 are assembled into a throat seal installation tool. When the throat seal is sleeved on the lower piston rod of the rubber pump and is stable, the second end of the joint 3 is in contact with the end surface of the throat seal, and the end surface of the lower piston rod is lower than the end surface of the throat seal. When the upper piston rod is lowered and the dismounting tool is pressed to press the throat seal downward, since the second end of the joint 3 is provided with an opening 301 extending to the first end of the joint 3, the diameter of the opening 301 is greater than the diameter of the lower piston rod of the rubber pump, therefore, as the throat seal moves downward, the lower piston rod protruding from the end surface of the throat seal can be accommodated in the opening 301 of the joint 3, so that the end surface of the second end of the joint 3 continues to be in contact with the end surface of the throat seal, so that the dismounting tool can continue to move downward, and the throat seal is completely pressed into the rubber pump installation groove. When the dismounting tool is removed, the wrench can be used to clamp the upper clamping part 103, the upper pressure rod 1 is further screwed into the joint 3, the length of the part of the upper pressure rod 1 extending into the joint 3 is increased, so that the height of the dismounting tool is reduced, the dismounting tool and the upper piston rod are separated, and the dismounting tool is more easily removed.

[0057] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
