Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive machines, and particularly relates to a PUR hot melt adhesive machine. Background Art

[0002] There are two types of PUR hot melt adhesive machines classified by the melting method, namely the melting tank type and the pressure plate type. The pressure plate type hot melt adhesive machine: the heating part is an aluminum alloy heating plate. When in use, the heating plate is pressed into the glue bucket from top to bottom. The heating plate is located above the glue. When the heating plate heats, only the upper layer of glue contacts the heating plate, so that it reaches the melting point and melts. The lower part of the glue bucket is not heated at this time. During production, as much glue as needed is melted, which can avoid the glue from aging and deteriorating due to long-term heating.

[0003] Currently, the existing pressure plate type hot melt machines generally include a bottom plate, a chassis, and a hot melting mechanism for hot melting the glue in the glue bucket. The hot melting mechanism and the chassis are respectively fixedly arranged on both sides of the top of the bottom plate, and the length of the hot melting mechanism is generally designed to be relatively large to place the glue bucket that needs hot melting treatment below. The bottom plate needs to reserve a large space, so the overall occupied space of the pressure plate type hot melt machine is large, which is not convenient for handling and storage when idle.

[0004] In view of this, it is necessary to provide a technical solution to solve the above problems. Content of the Utility Model

The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0027] It should be noted that the full name of PUR is moisture-curing reactive polyurethane hot melt adhesive, and its main component is terminal isocyanate polyurethane prepolymer. The adhesiveness and toughness of PUR can be adjusted, and it has excellent adhesive strength, heat resistance, chemical corrosion resistance, and aging resistance, and has become one of the important varieties in the adhesive industry.

[0028] Such as Figures 1 to 5As shown in the figure, a PUR hot melt adhesive machine includes a machine body 1, a mounting plate 2 rotatably connected to the machine body 1, and a hot melt module 3 disposed on the mounting plate 2. The glue bucket is placed on the mounting plate 2, and the hot melt module 3 is used to perform hot melting treatment on the glue in the glue bucket; the hot melt module 3 can be rotated and folded towards the machine body 1 through the mounting plate 2, and rotated and unfolded in a direction away from the machine body 1. Specifically, the hot melt module 3 is installed on the rotatable mounting plate 2, and the glue bucket is placed on the mounting plate 2. The hot melt module 3 is responsible for heating the PUR hot melt adhesive in the glue bucket to reach its melting point and melt. The mounting plate 2 and the machine body 1 are rotatably connected, enabling the hot melt module 3 and the mounting plate 2 to rotate and fold towards the machine body 1 or rotate and unfold in a direction away from the machine body 1 as a whole, improving the flexibility and portability of the hot melt adhesive machine. It should be noted that the operation process of this hot melt adhesive machine is controlled by a control box 14, including temperature adjustment of the hot melt module 3, heating time control, etc. Users can realize various functions of the hot melt adhesive machine through the operation interface on the control box 14.

[0029] In the present utility model, the hot melt module 3 and the mounting plate 2 can be rotated and folded, so that the hot melt adhesive machine can be folded when not in use, greatly reducing the occupied space and facilitating the handling and storage by the user. Compared with the traditional platen hot melt machine, this design has significant advantages in space utilization. When in use, the hot melt module 3 can be rotated and unfolded outward through the mounting plate 2.

[0030] In some embodiments of the present application, the machine body 1 includes a control box 14 and a base 11. The control box 14 is disposed on the base 11, and the base 11 has a connecting portion 12 for connecting with the mounting plate 2. Specifically, the machine body 1 is composed of two parts, the control box 14 and the base 11. The control box 14 is installed on the base 11 to form a stable structural foundation. The base 11 is provided with a connecting portion 12 for rotatably connecting with the mounting plate 2 to realize the rotation folding and unfolding functions of the hot melt module 3 and the mounting plate 2. The control box 14 is the core control component of the hot melt adhesive machine, responsible for receiving user instructions and controlling the working state of the hot melt module 3. Through the internal circuit and control system, the control box 14 can accurately adjust parameters such as the temperature and heating time of the hot melt module 3 to ensure the stability and efficiency of the hot melting process. The connecting portion 12 on the base 11 is the connection bridge between the mounting plate 2 and the machine body 1, and adopts a specific design (such as a pin shaft, hinge, etc.) to realize the rotatable connection of the mounting plate 2, enabling the mounting plate 2 to rotate and fold or unfold around the connecting portion 12. At the same time, the connecting portion 12 also needs to have a certain load-bearing capacity and stability to ensure the stability and safety of the hot melt module 3 and the mounting plate 2 during the working process.

[0031] In some embodiments of the present application, an opening 13 is formed on one side of the base 11. When the mounting plate 2 is in a folded state, the opening 13 allows a part of the mounting plate 2 to be inserted. Specifically, the opening 13 is formed on the right side of the base 11 to ensure that when the mounting plate 2 is in a folded state, the mounting plate 2 or a part of its structure can be smoothly inserted therein, avoiding the influence of the base 11 on the folding of the mounting plate 2. When the hot melt adhesive machine is not in use or needs to be stored or transported, the mounting plate 2 rotates towards the machine body 1 to reach the folded state. At this time, the mounting plate 2 is aligned with the opening 13 on the base 11.

[0032] In some embodiments of the present application, the machine body 1 is provided with a limiting member 4. The limiting member 4 cooperates with the mounting plate 2 to limit and fix the mounting plate 2 when it is in a folded state and an unfolded state. Specifically, the cooperation between the limiting member 4 and the mounting plate 2 ensures the stability of the hot melt adhesive machine in the folded and unfolded states, reducing the safety risks caused by equipment shaking or tipping over.

[0033] In some embodiments of the present application, the limiting member 4 includes a fixed block 41, a moving seat 42 having a card slot 421, and a driver 43. The shape of the card slot 421 matches that of the fixed block 41. The fixed block 41 is arranged on the mounting plate 2. The moving seat 42 is slidably connected to the machine body 1. The driver 43 is movably connected and can drive the moving seat 42 to slide, so that the fixed block 41 can be inserted into the card slot 421 and removed from the card slot 421. Specifically, the moving seat 42 is slidably connected to the machine body 1 through a chute, allowing the moving seat 42 to slide in a certain direction under the action of the driver 43. The driver 43 is connected to the moving seat 42. By controlling the output of the driver 43, the moving seat 42 is driven to slide on the guide rail. When it is necessary to fix the mounting plate 2, the driver 43 drives the moving seat 42 to slide downward, aligns the card slot 421 with the fixed block 41, and inserts the fixed block 41 into the card slot 421 to limit and fix the mounting plate 2. When it is necessary to release the mounting plate 2, the driver 43 drives the moving seat 42 to slide in the reverse direction, separating the card slot 421 from the fixed block 41, and the fixed block 41 is removed from the card slot 421, so that the mounting plate 2 can be rotated again to be adjusted to the folded state or the unfolded state. Through the matching of the fixed block 41 and the card slot 421, the precise limitation of the folded and unfolded states of the mounting plate 2 is realized, ensuring the stability and safety of the hot melt adhesive machine in different working states. The shape of the fixed block 41 can be set to include but not limited to square, polygon. The driver 43 can be set as an electric push rod or a cylinder according to requirements.

[0034] In some embodiments of the present application, the mounting plate 2 is provided with a first groove 21 for placing the glue bucket, which is used to position the glue bucket. Specifically, the shape of the first groove 21 matches the shape of the glue bucket, so as to ensure that the glue bucket can be placed tightly and stably in the groove. When the glue bucket is placed in the first groove 21, its bottom and side walls are in close contact with the bottom and side walls of the groove, thereby realizing the horizontal and vertical positioning of the glue bucket. This not only ensures the stability of the glue bucket during the hot melt process, but also avoids uneven hot melt or safety hazards caused by the shaking of the glue bucket. Users do not need to worry about the placement problem of the glue bucket. They only need to simply put the glue bucket into the groove to start the hot melt work, which improves the user experience and convenience.

[0035] In some embodiments of the present application, a plurality of second grooves 22 are provided at the bottom of the first groove 21. The plurality of second grooves 22 are arranged in a stepped manner in sequence, and the plurality of second grooves 22 and the first groove 21 are coaxially arranged. Specifically, the coaxial arrangement of the first groove 21 and the plurality of second grooves 22 ensures their spatial alignment and continuity, making the entire structure visually unified and functionally coordinated. The stepped arrangement of the plurality of second grooves 22 provides a diverse adaptation space for glue buckets of different diameters and heights. The height and width of each step correspond to different glue bucket sizes to match glue bucket sizes within a specific range. When a glue bucket needs to be placed, the user can choose to place it in the first groove 21 or any suitable second groove 22 according to the actual size of the glue bucket. Due to the coaxiality of the grooves, no matter which position is selected, the stability and positioning accuracy of the glue bucket can be ensured. Through the flexible combination of the first groove 21 and the plurality of second grooves 22, this design significantly enhances the compatibility of the hot melt glue machine with glue buckets of different sizes. This enables the same device to be applicable to more types of glue buckets, reducing the cost and frequency of equipment replacement. The number of the second grooves 22 is two.

[0036] In other embodiments, the number of the second grooves 22 can be set to 1, 3, 4, 5, 6, 7, or 8 according to requirements.

[0037] In some embodiments of the present application, the mounting plate 2 and the machine body 1 are also detachably connected. Specifically, when the mounting plate 2 or the hot melt module 3 needs to be repaired or replaced, the detachable connection between the mounting plate 2 and the machine body 1 enables the user to easily remove it and perform operations. This reduces the maintenance difficulty and time cost, and improves the reliability and service life of the equipment.

[0038] In some embodiments of the present application, two universal wheels are further provided at the bottom of the mounting plate 2. Specifically, the universal wheels are provided at the bottom of the mounting plate 2, which increases the moving flexibility when the hot melt module 3 rotates and shields or unfolds through the mounting plate 2, and reduces the frictional resistance between the mounting plate 2 and the ground; at the same time, it supports the mounting plate 2 and the hot melt module 3.

[0039] In other embodiments, the number of universal wheels can be set to 1, 3, 4, 5, 6, 7 or 8 according to requirements.

[0040] Based on the disclosure and teachings of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present utility model all fall within the protection scope of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
