Description

Technical Field

[0001] This utility model relates to the technical field of insulating adhesive production and processing, and in particular to a locking mechanism for the adhesive extraction tube of an insulating adhesive preparation machine. Background Technology

[0002] In the insulating adhesive production and processing industry, two-component insulating adhesive preparation machines typically have two vacuum preparation tanks. The insulating adhesive components A and B are drawn from the raw material tanks A and B into the corresponding vacuum preparation tanks for pretreatment such as stirring, degassing, or heating before dispensing. The adhesive extraction pipe, as a key component connecting the preparation machine and the raw material tanks and responsible for conveying the insulating adhesive, directly affects production efficiency and product quality.

[0003] The material preparation machine's suction tubes are usually distinguished by their colors, A and B. This poses a risk of inserting the wrong suction tube into the wrong material container, leading to material mixing. This can cause the insulating adhesive to cure prematurely in the material preparation container and the dispensing pipe. Furthermore, the traditional fixing methods, such as simple plug-in connections or rope bindings, are prone to loosening and falling off during the suction process when exposed to mechanical vibrations or external forces. This can result in the mixing of different insulating adhesive components, causing material waste, severely affecting product quality stability, and making the disassembly difficult and cumbersome when the suction tube needs to be replaced, increasing working time and labor costs.

[0004] Based on this, an improved adhesive extraction tube locking mechanism for an insulating adhesive preparation machine is proposed. Utility Model Content

[0005] In view of the problems mentioned above, such as the ease with which existing glue extraction tubes can be inserted into the wrong raw material container, leading to material mixing, and the difficulty and cumbersome disassembly when it is necessary to replace the glue extraction tube, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a glue extraction tube locking mechanism for an insulating adhesive preparation machine, including a bucket lid, a through hole inside the bucket lid, an annular groove on the upper outer surface of the bucket lid, a glue extraction tube inserted into the inner wall of the through hole, a fixing plate sleeved on the outer surface of the glue extraction tube, L-shaped plates fixedly connected to both sides of the bottom end of the fixing plate, a cylinder fixedly installed inside the vertical plate of the L-shaped plate, and an arc-shaped locking block fixedly connected to the telescopic shaft of the cylinder, the arc-shaped locking block being fitted into the inner wall of the annular groove.

[0007] As a preferred embodiment, the bottom end of the bucket lid is threaded to the top of the raw material bucket, and the bottom end of the glue extraction tube extends into the interior of the raw material bucket.

[0008] As a preferred embodiment, the bucket lid is provided with symmetrical limit pins on both sides, and the bottom end of the limit pins is fixedly connected to the top of the raw material bucket.

[0009] As a preferred embodiment, the L-shaped plate has a pin hole inside, the limiting pin is fitted into the inner wall of the pin hole, and the bottom end of the L-shaped plate is in contact with the top end of the raw material barrel.

[0010] As a preferred embodiment, the fixing plate includes a quick-release mechanism. A knob is provided on one side of the fixing plate, and a bidirectional lead screw is fixedly sleeved inside the knob. The bidirectional lead screw is rotatably connected to the inner wall of the transmission groove on one side of the fixing plate. Threaded sleeves are threaded to the outer surfaces of both ends of the bidirectional lead screw. A connecting rod is fixedly connected to one side of the threaded sleeve. A clamping plate is fixedly connected to the opposite side of the connecting rod. The clamping plate is disposed inside the fixing groove. An anti-slip pad is fixedly connected to the opposite side of the clamping plate. One side of the anti-slip pad is in contact with the outer surface of the glue extraction tube.

[0011] As a preferred embodiment, one end of the connecting rod is fixedly connected to a movable block, the movable block is slidably connected to the outer surface of the fixed rod, and the fixed rod is fixedly connected to the inner wall of the transmission groove on the other side of the fixed plate.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model achieves rapid installation and precise positioning through the insertion of the glue-drawing tube into the through hole and the engagement of the limiting pin into the pin hole, ensuring the accuracy and reliability of the locking mechanism. The locking mechanism, composed of a fixing plate, an L-shaped plate, a cylinder, an arc-shaped locking block, and an annular locking groove, firmly locks the fixing plate and the glue-drawing tube onto the bucket lid, effectively preventing the glue-drawing tube from being accidentally pulled out during the material suction process and avoiding the risk of mixing materials due to the glue-drawing tube being inserted into the wrong raw material bucket. This ensures the accuracy of material preparation and product quality, while also enabling rapid replacement of raw material buckets, improving material preparation efficiency and meeting the continuity requirements of the production process.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a locking mechanism for a glue extraction tube for an insulating glue preparation machine. It includes a bucket cover 1, a through hole 11 inside the bucket cover 1, an annular groove 12 on the upper outer surface of the bucket cover 1, a glue extraction tube 2 inserted into the inner wall of the through hole 11, a fixing plate 4 sleeved on the outer surface of the glue extraction tube 2, and L-shaped plates 5 fixedly connected to both sides of the bottom end of the fixing plate 4. A cylinder 6 is fixedly installed inside the vertical plate of the L-shaped plate 5, and an arc-shaped locking block 7 is fixedly connected to the telescopic shaft of the cylinder 6. The arc-shaped locking block 7 is fitted into the inner wall of the annular groove 12.

[0023] The bottom end of the bucket lid 1 is threaded to the top of the raw material bucket 3, and the bottom end of the glue extraction tube 2 extends into the inside of the raw material bucket 3.

[0024] Limiting pins 31 are symmetrically arranged on both sides of the barrel lid 1, and the bottom end of the limiting pins 31 is fixedly connected to the top of the raw material barrel 3.

[0025] The L-shaped plate 5 has a pin hole 51 inside, and the limiting pin 31 is fitted into the inner wall of the pin hole 51. The bottom end of the L-shaped plate 5 is in contact with the top end of the raw material barrel 3.

[0026] During use, first, the bucket lid 1 is installed on the top of the raw material bucket 3 by thread. The glue extraction tube 2 is inserted into the through hole 11 inside the bucket lid 1, so that the bottom end of the glue extraction tube 2 extends into the inside of the raw material bucket 3. At the same time, the fixing plate 4 is fitted on the outer surface of the glue extraction tube 2. The pin hole 51 on the horizontal plate of the L-shaped plate 5 is aligned with the limiting pin 31 at the top of the raw material bucket 3, so that the limiting pin 31 is fitted into the inner wall of the pin hole 51. At this time, the bottom end of the horizontal plate of the L-shaped plate 5 is in contact with the top of the raw material bucket 3, thus completing the initial installation and positioning. The cooperation between the limiting pin 31 and the pin hole 51 plays the role of auxiliary positioning and stabilizing the L-shaped plate 5, ensuring the accuracy and reliability of the locking mechanism.

[0027] Next, the cylinder 6 inside the vertical plate of the L-shaped plate 5 is activated. The telescopic shaft of the cylinder 6 pushes the arc-shaped locking block 7 to extend, so that the arc-shaped locking block 7 is fitted into the inner wall of the annular slot 12, thereby firmly locking the fixing plate 4 and the glue extraction tube 2 sleeved in the fixing plate 4 onto the bucket lid 1. This can achieve mutual fixation between the glue extraction tube 2 and the bucket lid 1, thereby preventing the glue extraction tube 2 from being accidentally pulled out during the material suction process, preventing the mixing of different raw materials such as insulating glue A and B components, and ensuring the accuracy of material preparation and product quality.

[0028] When replacing raw material barrel 3, the operator scans the batch QR code on the new raw material barrel 3 or the color of the raw material barrel to identify whether it is currently insulating adhesive component A or component B. Then, the operator controls the telescopic shaft of cylinder 6 to retract, causing the arc-shaped locking block 7 to disengage from the inner wall of the annular locking groove 12, releasing the lock on the fixing plate 4 and the glue extraction tube 2. Then, the glue extraction tube 2 can be removed from the through hole 11, thereby unlocking the corresponding barrel cover 1. This avoids the risk of mixing materials due to the glue extraction tube 2 being inserted into the wrong raw material barrel 3. At the same time, it enables quick replacement of raw material barrel 3, improves material preparation efficiency, and meets the continuous production process requirements.

[0029] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the fixing plate 4 includes a quick-release mechanism 8. A knob 81 is provided on one side of the fixing plate 4. A bidirectional screw 82 is fixedly sleeved inside the knob 81. The bidirectional screw 82 is rotatably connected to the inner wall of the transmission groove 42 on one side of the fixing plate 4. Both ends of the bidirectional screw 82 are threaded with screw sleeves 83. A connecting rod 84 is fixedly connected to one side of the screw sleeve 83. A clamping plate 85 is fixedly connected to the opposite side of the connecting rod 84. The clamping plate 85 is provided inside the fixing groove 41. An anti-slip pad is fixedly connected to the opposite side of the clamping plate 85. One side of the anti-slip pad is in contact with the outer surface of the glue extraction tube 2.

[0030] One end of the connecting rod 84 is fixedly connected to a movable block 86, which is slidably connected to the outer surface of the fixed rod 87. The fixed rod 87 is fixedly connected to the inner wall of the transmission groove 42 on the other side of the fixed plate 4.

[0031] During use, when it is necessary to replace the glue extraction tube 2, turn the knob 81 in the opposite direction. The knob 81 drives the bidirectional lead screw 82 to rotate in the opposite direction in the transmission groove 42, so that the threaded sleeves 83 at both ends move in opposite directions along the lead screw. The threaded sleeves 83 drive the clamping plates 85 to move synchronously through the connecting rod 84, so that the two clamping plates 85 that originally tightly clamped the glue extraction tube 2 gradually separate, releasing the restraint on the glue extraction tube 2. At this time, the glue extraction tube 2 can be easily pulled out from the fixing groove 41 of the fixing plate 4.

[0032] After the glue extraction tube 2 is pulled out, place the new glue extraction tube 2 in a suitable position in the fixed groove 41, turn the knob 81 in the forward direction, repeat the above screw transmission process, so that the two clamping plates 85 move towards each other, and firmly clamp the new glue extraction tube 2 through the anti-slip pad.

[0033] This design, by rotating the knob 81, enables quick clamping and releasing of the glue extraction tube 2 without the need for complex tools or cumbersome operating procedures, greatly improving the replacement efficiency of the glue extraction tube 2 and saving time and labor costs. On the other hand, it can adapt to glue extraction tubes 2 with different outer diameters. As long as the glue extraction tube 2 can be placed in the fixing groove 41, it can be firmly clamped by rotating the knob 81, which has strong versatility and adaptability.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
