Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel manufacturing technology, specifically relating to a hot melt adhesive processing reaction vessel. Background Technology

[0002] The hot melt adhesive processing reactor is the core equipment in the hot melt adhesive production process, mainly used for processes such as mixing, heating, chemical reaction and polymerization of raw materials;

[0003] When the raw materials are stirred in the reactor, the local pressure decreases due to the high-speed shearing of the raw materials. This causes dissolved gases (such as air and CO2) to precipitate out and form bubbles that float on the surface of the original liquid. If these surface bubbles are not broken in time, they may be encapsulated in the melt during subsequent vacuum degassing, forming dispersed micropores. This leads to a decrease in the tensile strength and peel strength of the material (e.g., EVA hot melt adhesive is prone to cracking when used for bonding cardboard boxes).

[0004] Currently, in response to the bubbles formed, some reactors have been designed with defoaming blades that can float on the surface of the raw liquid. These defoaming blades can rotate with the stirring rod to puncture the bubbles on the surface of the raw liquid, thereby improving the defoaming rate and thus enhancing product quality.

[0005] However, since the defoaming blades float on the surface of the original liquid and the driving component drives the stirring rod to rotate the defoaming liquid on the surface of the original liquid, when stirring the original liquid with high viscosity, in order to overcome its adhesion force, it is easy to cause overload of the driving component, which affects the service life of the driving component.

[0006] In view of this, the present invention provides a hot melt adhesive processing reactor to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hot melt adhesive processing reactor, comprising a reactor body, a driving component axially disposed at the bottom of the reactor body, the movable end of the driving component being sealed and inserted into the bottom of the reactor body and axially connected to a transmission rod, and a stirring rod being fixedly sleeved on the periphery of the transmission rod;

[0008] The transmission rod is movably equipped with a suspension defoaming component that can suspend on the surface of the raw material liquid inside the reactor body and make circular motion.

[0009] As a preferred embodiment of the hot melt adhesive processing reactor of this utility model, the suspension defoaming component includes a floating component sleeved around the transmission rod and a first magnet connected to the top surface of the floating component.

[0010] As a preferred embodiment of the hot melt adhesive processing reactor of this utility model, it further includes a driven member that is slidably sleeved on the periphery of the transmission rod and rotates with the transmission rod. The periphery of the driven member is provided with radially extending defoaming blades, and the bottom surface of the driven member is connected to a second magnet.

[0011] In a preferred embodiment of the hot melt adhesive processing reactor of this utility model, the driven member is located above the floating member;

[0012] The second magnet and the first magnet have the same magnetism on their opposite surfaces.

[0013] As a preferred embodiment of the hot melt adhesive processing reactor of this utility model, the transmission rod has a groove extending along its axial direction on its circumference, and the driven member has a slider extending into the groove on its inner side.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes the identical magnetic properties of the first and second magnets to allow the driven component above the floating component to suspend above the surface of the original liquid with a small gap between it and the original liquid, thus avoiding direct contact with the surface of the original liquid. Consequently, when the driving component drives the transmission rod to rotate, the driving component does not need to overcome the adhesive force of the original liquid, thereby effectively reducing the load on the driving component and improving its service life.

[0022] 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.

[0023] This utility model relates to a hot melt adhesive processing reactor, such as... Figure 1 As shown, the reactor includes a reactor body 1. A drive component 2 is axially arranged at the bottom of the reactor body 1. The movable end of the drive component 2 is sealed and inserted into the bottom of the reactor body 1 and axially connected to a transmission rod 3 through a coupling. A stirring rod 4 for stirring raw materials is fixedly sleeved on the periphery of the transmission rod 3. A suspension defoaming component 5 that can suspend on the surface of the raw material liquid inside the reactor body 1 and make circular motion is movably arranged on the periphery of the transmission rod 3.

[0024] Specifically, such as Figures 2-4 As shown, the suspension defoaming assembly 5 includes a hollow floating component 51 sleeved around the drive rod 3, and a first magnet 52 connected to the top surface of the floating component 51. The floating component 51 can adaptively move along the axial direction of the drive rod 3 according to the height of the raw liquid added into the reactor body 1, so as to float on the surface of the raw liquid. In actual defoaming applications, the floating component 51 should be designed to be flat to reduce the height difference between its top surface and the surface of the raw liquid.

[0025] The suspension defoaming assembly 5 also includes a driven member 53 that is slidably sleeved around the transmission rod 3 and rotates with the transmission rod 3. Radially extending defoaming blades 55 are provided around the driven member 53. A second magnet 54 is connected to the bottom surface of the driven member 53. The first magnet 52 and the second magnet 54 are arranged opposite each other, and their opposing surfaces have the same magnetism. Therefore, when the driven member 53 is sleeved around the transmission rod 3, the second magnet 54 will suspend above the first magnet 52 under the influence of magnetism. In actual defoaming applications, the driven member 53 should also be designed to be flat, similar to the floating member 51.

[0026] In order to achieve synchronous rotation of the driven member 53 and the transmission rod 3, and axial movement on the transmission rod 3 to follow the movement of the floating member 51, a groove 31 extending along its axial direction is provided on the periphery of the transmission rod 3. In this embodiment, in order to improve its sliding stability, the groove 31 is symmetrically provided on the periphery of the transmission rod 3. At the same time, a slider 56 extending into the groove 31 is connected to the inner side of the driven member 53.

[0027] Furthermore, when the driving component 2 drives the transmission rod 3 to rotate, the driven component 53 will drive the defoaming leaf 55 to rotate and cut the bubbles generated on the surface of the original liquid under the cooperation between the slider 56 and the slide groove 31. At the same time, it can also follow the position of the floating component 51 and adaptively adjust its own position height to meet the defoaming requirements of the original liquid at different heights.

[0028] Taking hot melt adhesive processing as an example, the principle of this utility model is explained in detail: The hot melt adhesive raw material has a high viscosity. After its original liquid is filled in the main body 1 of the reaction vessel, the floating part 51 can float on the surface of the original liquid. Under the same magnetic action between the first magnet 52 and the second magnet 54, a repulsive force is generated, causing the driven part 53 to suspend above the floating part 51, thereby forming a tiny gap on the surface of the original liquid. When the driving part 2 drives the transmission rod 3 to rotate, the driven part 53 drives the defoaming leaf 55 to rotate to cut the bubbles. Since the defoaming leaf 55 does not directly contact the high-viscosity original liquid, the load on the driving part 2 is small, thereby effectively improving its service life.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
