Description

Technical Field

[0001] This utility model relates to the technical field of concentration detection devices, specifically a concentration detection device for the production of superheated melt adhesive. Background Technology

[0002] Hot melt adhesive is a type of plastic adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product.

[0003] Because its products are solid, they are easy to package, transport, and store; they are solvent-free, pollution-free, and non-toxic; and they have advantages such as simple production process, high added value, strong adhesion, and fast speed.

[0004] However, during the production of superheated melt adhesive, a concentration detection device is required to detect the concentration of the superheated melt adhesive. Only after the concentration is qualified can the superheated melt adhesive be cooled and molded. Most existing superheated melt adhesive concentration detection devices require workers to manually suspend a densitometer in the liquid of the hot melt adhesive to be tested and detect it through the densitometer. However, after the test is completed and the densitometer is removed from the solution, the solution adhering to the surface of the densitometer is easy to drip onto the surface of the placement table, thus causing the table surface to be contaminated. Therefore, a concentration detection device for superheated melt adhesive production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a concentration detection device for the production of superheated melt adhesive. By providing a receiving tray below the densitometer body that can rotate according to the rise and fall of the densitometer body to receive the solution dripping from the densitometer body, the problem mentioned in the background art is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concentration detection device for the production of superheated melt adhesive includes a workbench and a densitometer body. The surface of the workbench is provided with a lifting mechanism for moving the densitometer body up and down, and the other side of the workbench surface is provided with a receiving mechanism for receiving the solution dripping from the densitometer body.

[0008] The receiving mechanism includes a receiving tray, which is fixedly installed on the side wall of the rotating column. The original position of the receiving tray is located directly below the densitometer body, and the rotating column is rotatably mounted on the surface of the worktable.

[0009] The surface of the workbench, located below the densitometer body, is also equipped with a container for holding the solution to be tested.

[0010] Preferably, the receiving mechanism further includes a spring, which is sleeved on the outer arc surface of the rotating column, and the bottom surface of the spring is fixedly installed with the surface of the worktable, and the other end of the spring is fixedly installed with the outer arc surface of the rotating column.

[0011] Preferably, the receiving mechanism still includes a lower pressure plate, one end of which is fixedly installed with the lifting mechanism. A protruding post is provided on the side wall of the rotating column above the spring. The side wall of the lower pressure plate facing the protruding post is inclined. The lower pressure plate is slidably connected to the outer arc surface of the protruding post.

[0012] Preferably, the lifting mechanism includes a vertical frame, a movable block, and a drive assembly. The vertical frame is fixedly installed on one side of the workbench surface. A groove is provided on the side wall of the vertical frame. The movable block is slidably disposed inside the groove under the drive of the drive assembly. A connecting rod is provided on the side of the movable block facing the receiving mechanism. A support plate is fixedly installed on the side wall of the connecting rod. The densitometer body is suspended below the support plate. The lower side wall of the connecting rod is also fixedly installed to the end of the lower pressure plate.

[0013] Preferably, the drive assembly includes a servo motor and a threaded rod. The servo motor is fixedly mounted on the top surface of the vertical frame. The working end of the threaded rod passes through the top surface of the vertical frame and is keyed to the output shaft of the servo motor. The bottom end of the threaded rod is rotatably disposed on the inner bottom surface of the slide groove. The moving block is threadedly sleeved on the outer arc surface of the threaded rod.

[0014] Preferably, the loading mechanism includes a solution tank and a loading platform. The loading platform is slidably disposed on the surface of the workbench. A placement groove is formed on the surface of the loading platform. The solution tank is placed inside the placement groove and is positioned directly below the densitometer body.

[0015] Preferably, the surface of the workbench is provided with a square groove, and a toothed rod is rotatably installed inside the square groove. The end of the toothed rod that passes through the side wall of the workbench is fixedly installed with a handle. The bottom end of the platform is threadedly sleeved on the outer arc surface of the toothed rod, and the platform is slidably connected to the bottom side wall of the toothed rod and the inner wall of the square groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a rotatable receiving tray located below the densitometer body. When the densitometer body descends under the drive of the lifting mechanism, the lower pressure plate presses against the protruding column, causing the rotating column to rotate. This moves the receiving tray away from below the densitometer body, allowing the densitometer body to detect the concentration of the hot melt adhesive solution inside the solution tank. After the detection is complete, the lifting mechanism raises the densitometer body, and the rotating column, under the rebound force of the spring, rotates in the opposite direction, causing the receiving tray to rotate directly below the densitometer body. The receiving tray then collects the solution dripping from the densitometer body, thus preventing the solution from contaminating the workbench. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] A concentration detection device for overheated melt adhesive production includes a workbench 1 and a densitometer body 9. The surface of the workbench 1 is provided with a lifting mechanism for driving the densitometer body 9 to move up and down. On the other side of the surface of the workbench 1, a receiving mechanism 10 is provided for receiving the solution dripping from the densitometer body 9.

[0026] The receiving mechanism 10 includes a receiving tray 15, which is fixedly installed on the side wall of the rotating column 12. The original position of the receiving tray 15 is located directly below the densitometer body 9, and the rotating column 12 is rotatably mounted on the surface of the workbench 1.

[0027] The surface of the workbench 1, located below the densitometer body 9, is also equipped with a container for holding the solution to be tested.

[0028] By setting the receiving tray 15 directly below the densitometer body 9 and fixing the receiving tray 15 to the rotating column 12, the rotating column 12 is rotatably mounted on the surface of the workbench 1, so that the densitometer body 9 can be lowered by the lifting mechanism, causing the rotating column 12 to rotate, which in turn drives the receiving tray 15 to rotate, thus facilitating the placement of the densitometer body 9 into the solution inside the solution tank 17 below for concentration detection. After the detection is completed, the densitometer body 9 is raised, and the receiving tray 15 rotates back to directly below the densitometer body 9 to collect the solution dripping from the densitometer body 9, preventing the solution from dripping onto the workbench surface and causing contamination.

[0029] The receiving mechanism also includes a spring 13, which is sleeved on the outer arc surface of the rotating column 12, and the bottom surface of the spring 13 is fixedly installed on the surface of the worktable 1. The other end of the spring 13 is fixedly installed on the outer arc surface of the rotating column 12.

[0030] The receiving mechanism still includes a lower pressure plate 11. One end of the lower pressure plate 11 is fixedly installed with the lifting mechanism. A protruding post 14 is provided on the side wall of the rotating column 12 above the spring 13. The side wall of the lower pressure plate 11 facing the protruding post 14 is inclined. The lower pressure plate 11 and the outer arc surface of the protruding post 14 are slidably connected.

[0031] Meanwhile, a spring 13 is sleeved on the outside of the rotating column 12, and the bottom end of the spring 13 is fixedly installed on the surface of the workbench 1. The top end of the spring 13 is fixedly installed on the outer arc surface of the rotating column 12. At the same time, a protruding post 14 is provided on the outer arc surface of the rotating column 12 above the spring 13. The protruding post 14 is slidably connected to the inclined side wall of the lower pressure plate 11. When the densitometer body 9 descends, it drives the lower pressure plate 11 to descend, causing the lower pressure plate 11 to squeeze the protruding post 14, thereby driving the rotating column 12 to rotate. This causes the receiving tray 15 to rotate away from below the densitometer body 9, and the densitometer body 9 enters the solution inside the solution tank 17 below to detect the concentration of the superheated melt adhesive solution. After the detection is completed, the densitometer body 9 rises, and the rotating column 12 is reset under the action of the external spring 13. This realizes the receiving tray 15 rotating to the bottom of the densitometer body 9 to receive the solution dripping from the densitometer body 9.

[0032] The lifting mechanism includes a vertical frame 2, a movable block 4, and a drive assembly. The vertical frame 2 is fixedly installed on one side of the surface of the workbench 1. A groove 6 is provided on the side wall of the vertical frame 2. The movable block 4 is slidably disposed inside the groove 6 under the drive of the drive assembly. A connecting rod 7 is provided on the side of the movable block 4 facing the receiving mechanism 10. A support plate 8 is fixedly installed on the side wall of the connecting rod 7. The densitometer body 9 is suspended below the support plate 8. The lower side wall of the connecting rod 7 is also fixedly installed to the end of the lower pressure plate 11. The drive assembly includes a servo motor 3 and a threaded rod 5. The servo motor 3 is fixedly installed on the top surface of the vertical frame 2. The working end of the threaded rod 5 passes through the top surface of the vertical frame 2 and is keyed to the output shaft of the servo motor 3. The bottom end of the threaded rod 5 is rotatably disposed on the inner bottom surface of the groove 6. The movable block 4 is threadedly sleeved on the outer arc surface of the threaded rod 5.

[0033] Meanwhile, the densitometer body 9 is suspended below the support plate 8, and the support plate 8 is fixedly installed on the side wall of the connecting rod 7. The end of the connecting rod 7 is fixedly installed with the moving block 4, and the side wall of the connecting rod 7 is fixedly installed with the end of the lower pressure plate 11. When the servo motor 3 starts and drives the threaded rod 5 to rotate, the moving block 4 moves up and down along the outer arc surface of the threaded rod 5 along the slide groove 6, thereby driving the densitometer body 9 and the lower pressure plate 11 to move up and down. This realizes that the lower pressure plate 11 lowers and squeezes the protruding column 14 to drive the rotating column 12 to rotate, thereby causing the receiving tray 15 to rotate away from below the densitometer body 9, so that the densitometer body 9 can detect the concentration of the solution inside the solution tank 17.

[0034] The loading mechanism includes a solution tank 17 and a loading platform 20. The loading platform 20 is slidably disposed on the surface of the workbench 1. A placement groove is provided on the surface of the loading platform 20. The solution tank 17 is placed inside the placement groove and is located directly below the densitometer body 9. A square groove 16 is provided on the surface of the workbench 1. A toothed rod 18 is rotatably disposed inside the square groove 16. The end of the toothed rod 18 that passes through the side wall of the workbench 1 is fixedly installed with a handle 19. The bottom end of the loading platform 20 is threaded onto the outer arc surface of the toothed rod 18. The loading platform 20 is slidably connected to the bottom side wall of the toothed rod 18 and the inner wall of the square groove 16.

[0035] Meanwhile, a platform 20 is also provided to slide on the surface of the workbench 1. After the densitometer body 9 finishes testing and rises, the testing personnel can manually turn the handle 19 to drive the platform 20 to slide the solution tank 17 away from under the densitometer body 9, which makes it easier for workers to take the solution tank 17 out for cleaning and avoids the solution tank 17 getting contaminated by solution when it is taken out from under the densitometer body 9.

[0036] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
