Description

[0001] summary

[0002] The patent application of this invention relates to an industrial thermoplastic adhesive applicator with portable and manual features, which mainly consists of a central heating and cooling control unit of the manual applicator itself, which is housed in the heating and cooling control unit, and at least one manual applicator is envisioned for each of the units. Technical Field

[0003] This invention relates to a segment of the thermoplastic adhesives industry, particularly for leather, rubber, fabrics, synthetic laminates, paper and cardboard, wood, metals, etc.

[0004] Specifically, its application is general-purpose and is used to apply thermoplastic adhesives in the form of smooth patterns, textures, and undulating trails, the trail pattern being related to the pattern of the applicator nozzle. On the substrate to be bonded, the applied pattern can be linear or curved, point-to-point or continuous.

[0005] Depending on the properties of the adhesive to be used, the technology according to the present invention is applicable to leather, synthetics, paper, fabrics, wood, metals, etc.

[0006] This invention also replaces double-sided adhesive tape, thus enabling it to be used only in applications involving one of the two substrates to be joined.

[0007] It can be applied to the manufacturing of clothing, bags, shoes, wallets, handicrafts, packaging, furniture and other industries. That is, in places where there is a clear fastening or pre-set positioning, there are other clear fastening methods, such as sewing or riveting.

[0008] The product’s features and solutions in terms of technology, operational safety, materials used, and ergonomics indicate that it is intended for industrial applications, but can be adapted for a variety of general uses, such as homes, schools, and laboratories, through optional interchangeable nozzles. Background Technology

[0009] There is currently no known portable manual industrial thermoplastic adhesive applicator product with the technical features, structural form, and industrial design described in this article, which is to be expected when comparing the relevant technologies, solutions, ergonomics, and industrial sectors.

[0010] However, we noticed that some products with similar features were not translated into the required range, as shown below:

[0011] - Heated applicator for hair removal and body beauty;

[0012] - Thermoplastic adhesive applicator device manufactured by Morbach Company in Novo Hamburgo, RS: This device is used for applying thermoplastic adhesives, is a horizontal trolley type with an adhesive level container, is heated by electrical resistance, is connected to an electrical control unit via a power cord and sensor wire, has a handle in a horizontal position, and has an applicator nozzle;

[0013] - Gun-type thermoplastic adhesive applicator device with trigger that pushes a solid adhesive stick toward a heated nozzle, originating in China.

[0014] Document CA1067870, issued on December 11, 1979, describes a manual spray gun applicator for dispensing hot melt adhesives used in an adhesive dispenser system. The manual spray gun includes a novel loading valve structure adapted to interlock with a novel supply valve structure mounted on a hot melt adhesive source to perform the transfer of a load of molten hot melt adhesive from the source to the spray gun's storage chamber. A driving force is provided by pressurizing the adhesive within the spray gun's storage chamber via a novel pressure device at least partially embedded therein, causing the molten adhesive to be expelled from the nozzle of the spray gun in response to manual activation of the spray gun trigger.

[0015] Document CN210100571, published on February 21, 2020, describes a circular side-feed tip-type hot chamber device. The device includes a cooling mechanism and a hydraulic rod. A base is mounted on one side of the cooling mechanism; a nozzle is provided on the base; a main flow chamber is mounted above the base; protective mechanisms are mounted on the left and right sides of the main flow chamber; a heating tube is provided in the main flow chamber, and a guide chamber is provided in the heating tube. A filling opening is formed in the upper part of the main flow chamber, and a through hole is formed in the filling opening. An ejector block is provided above the through hole, and a pressure rod is provided above the ejector block, with the hydraulic rod positioned above the pressure rod. This circular side-feed tip-type hot chamber device is equipped with protective mechanisms. A fastening structure restricts the position of the stainless steel mesh, and a connecting rod can effectively separate the stainless steel mesh from the main flow chamber. Therefore, the user is kept at a certain distance from the main flow chamber, preventing burns and providing effective protection for the user.

[0016] Document MU8500114 consists of a heated reservoir capable of loading hot-melt adhesive in granular form or cubically smaller than the reservoir opening. Strategically positioned cylinder resistance heats the reservoir at temperatures that interfere with the physical state of the adhesive, and the reservoir temperature is controlled by a blade-type thermostat. The upper part of the reservoir is located at the adhesive supply port, which is equipped with a sealed cap containing a rest support. A metering nozzle, located at the front of the reservoir, applies the adhesive to the surface to be bonded. At the bottom of the reservoir is a cylinder in which a plunger operates, carrying the molten adhesive to the metering nozzle. This plunger is activated by a lever connected to a drive trigger. When the drive trigger is pressed, the trigger pushes a piston forward via the lever to carry the adhesive to the metering nozzle, applying it to the desired surface. When the trigger returns, the piston returns and the cylinder of the reservoir is refilled by suction, thus ending the work cycle.

[0017] In short, all the documents from the proposed technology firstly have complex structures, and similarly, none of them describe in a simple way the heating and cooling control unit connected to at least one applicator, in which the heating and cooling control unit is always maintained at an ideal temperature.

[0018] Regarding heated wax applicators used for hair removal and human aesthetics, specifically, the health and aesthetics segment, this product does not reach the temperature required to soften thermoplastic adhesives.

[0019] However, if this were done, its handling would be unlikely, because the handles of these products do not have sufficient insulation, nor do they have forced cooling to ensure safe handling.

[0020] The push-type thermoplastic adhesive applicator is designed for industrial applications, but its freedom of movement in the application is limited because it is ergonomically designed for horizontal use.

[0021] The push-type applicator uses an electric heating resistor next to the applicator body, so it includes a power supply wire for the heating resistor and a wire with a temperature sensor.

[0022] The push-type thermoplastic applicator was developed for horizontal applications, with its thermoplastic storage capacity prioritizing maximum volume over handling flexibility.

[0023] In other words, in the architectural framework of a push-type applicator, the applicator nozzle is fixed to a reservoir base, followed by a thermoplastic reservoir, and finally a horizontally positioned handle surrounding the power cable. In other words, it's a product whose freedom of movement for operation and use is limited to horizontal use, lacking the ergonomics of portable operation.

[0024] The purpose of developing gun-type applicators is to inject the adhesive you wish to bond. A continuous and uniform bond cannot be achieved on a flat surface.

[0025] In addition, gun-type thermoplastic adhesive applicators are specifically developed for one or a class of solid adhesives with specific hardness and consistency.

[0026] Gun-type thermoplastic adhesive applicators were developed only for adhesive sticks of a pre-defined size and cannot be used with other physical forms of adhesive, such as granular adhesives or pouch adhesives.

[0027] The gun-type thermoplastic adhesive applicator is developed from a heated funnel-shaped nozzle in which a thermoplastic rod is compressed, melted, and extruded by the user's action of pressing a trigger. The applicator is heated by a piezoelectric composite ceramic insert, which begins to heat and conducts heat to the funnel when power is received directly from a power outlet via a power line.

[0028] The gun's electrical components consist of a single-phase plug socket without grounding, a ceramic insert, and a two-conductor power cable. One end of the two-conductor power cable is connected to the plug socket, and the other end is directly connected to the ceramic insert.

[0029] This circuit, installed as a heating system, does not consider operational safety because it does not include a main switch, fuse, grounding, or any type of temperature control. Therefore, it is not suitable for any type of use, whether industrial, professional, personal, or school, etc.

[0030] Advantages of the present invention

[0031] This invention relates to a manual, portable, wireless thermoplastic adhesive applicator designed to be operated like a pen, marker, or writing pen, with a wide range of degrees of freedom of movement when applying adhesive.

[0032] Another advantage is that the applicator is lightweight and ergonomic, easy to operate due to its small size, and the space inside the handle or body serves as a molten reservoir for the adhesive applied by the nozzle.

[0033] Furthermore, the developed portable system offers maximum safety against electric shock, poor contact, sparks, or short circuits in the applicator because it is portable and has wireless power for heating. Heating is generated and replaced within the applicator, and the heat energy is collected and cooled by the cable cover after intermittent use through the base unit where the applicator is located. The base unit includes electrical installation items such as a main disconnect switch, overload fuse, on / off service switch, indicator lights, double-covered power cable, and digital temperature controller.

[0034] Although the applicator contains an adhesive that heats at high temperatures in its reservoir, the handle's outer casing keeps it at a safe temperature during processing thanks to a thermal insulation system made of a material with low thermal conductivity and a heat sink design suitable for air circulation cooling.

[0035] Thermoplastic coating technology includes replaceable applicator nozzles developed for a variety of needs, from width to height variations. The corresponding drawings determine the degree of flexibility or adhesive bonding.

[0036] The solution developed in this project has been transformed into a product that is extremely useful for industrial production, where the flexibility, simplicity, and accuracy in thermoplastic adhesive applications can save on operating costs.

[0037] In addition to the advantages and benefits that are obvious from the above description, other advantages and benefits can be listed, namely:

[0038] - Portable wireless applicator;

[0039] - Lightweight and ergonomic, it can also be used as a pen;

[0040] - When applying adhesive, there is a wide range of freedom of movement;

[0041] - Hold the handle like a writing pen;

[0042] - Applicator holder base with thermal control heating system;

[0043] - Electromagnetic induction and electrical induction heating systems;

[0044] - A heating or cooling system generated by the applicator's cap;

[0045] - The inside of the handle or body acts as a molten reservoir for the adhesive applied by the nozzle;

[0046] - The applicator unit system is wire-free, safe, and durable;

[0047] - Replaceable applicator nozzles developed to meet various application needs;

[0048] - Applicator with thermal energy storage for greater autonomy and faster charging speed.

[0049] In the preferred summary form of this invention, the following aspects are highlighted:

[0050] - The applicator (applying pen) has an anatomical shape and is portable, requiring no wires. For example, it can be used manually or connected to a CNC machine tool;

[0051] - The applicator (pen) does not require an auxiliary device to heat the adhesive within the applicator (pen) itself. Heat induction is used to ensure the adhesive softens, allowing it to remain at the application point (liquid) for sufficient time for industrial use;

[0052] - The fact that no wires or other connections to the central heating control unit are required allows for complete freedom of movement and ensures the safety of the user, who does not have direct contact with wires, resistors or other components;

[0053] - During application, there is no need to install auxiliary devices inside or outside the applicator body to facilitate the pumping of the adhesive; the dynamics generated by the construction and application movement itself are utilized.

[0054] - The applicator (pen) is designed to facilitate the sealing of the adhesive when stationary and to facilitate the pumping of the adhesive when in motion, thereby achieving uniform and continuous application.

[0055] - The handle of the applicator (pen) is designed to promote external cooling of the handle, ensure operator comfort, and maintain the temperature of the adhesive inside the handle through the heat insulation layer employed.

[0056] Description of the present invention

[0057] The present invention includes a central heating and cooling control unit for an applicator, including a manual applicator distributed in the central heating control unit, and at least one applicator is applied to the unit, and two, three or more applicators can be used simultaneously when stationary.

[0058] To illustrate, a suitable explanation is that heat-resistant plastic adhesives primarily used in industry soften (liquefy) at temperatures above 100 degrees Celsius, depending on the compound. The vast majority require temperatures exceeding 120 degrees Celsius, and some may require temperatures approaching 200 degrees Celsius. Therefore, the adhesive must reach these temperatures inside the applicator's handle. For this purpose, a central heating control unit needs to generate this temperature and transfer it to the applicator, which then re-transfers the adhesive within its interior. The applicator must also maintain this heat within its interior for a period equal to or greater than the time required to dispense or apply the adhesive. Simultaneously, the outer surface of the handle needs to remain cool to ensure safety and comfort during use.

[0059] Technically, the applicator body has an ergonomic design, allowing for manual application of adhesive in a manner similar to a writing pen or marker. The applicator consists of a cover for the handle, which insulates the handle from heat in the area in contact with the operator's hand. The interior of the applicator handle functions as a reservoir where the adhesive to be applied melts.

[0060] The thermoplastic adhesive is applied via a dynamically rotating nozzle fixed to the lower end of the handle. The applied adhesive trajectory reflects the design and dimensions of the applicator nozzle.

[0061] The applicator is heated in the central heating control unit, wherein the applicator is in a stationary state, the heat energy in the heating support is collected by the thermal energy accumulator of the applicator, and the cover of the body is cooled by active cooling caused by air circulation (9).

[0062] The heating system of the applicator is activated by electromagnetic induction or resistance, depending on its intended use.

[0063] The applicator's system and design are "wireless," meaning portable and wireless.

[0064] The applicator is constructed from a combination of spare, replaceable parts that perform physical functional characteristics when working together.

[0065] In application, the applicator transfers adhesive to the surface of the material, the physical shape of which is predetermined by the applicator's nozzle. The applied area is uniform in size and has a smooth pattern or texture, thereby allowing for the measurement and balancing of adhesive consumption and yield as needed.

[0066] The central heating control unit, which houses the applicator, contains circuitry, a thermal controller with sensors, a main electrical switch, a heating on / off switch, indicator lights, and a power cable.

[0067] The purpose of this invention

[0068] The purpose of this invention is to provide a portable thermoplastic adhesive applicator for applying heat-activated adhesive dropwise to the surface of materials to be bonded, such as leather, rubber, fabric, synthetic laminate, paper and cardboard, wood and metal, by means of a rotating, spherical or injection nozzle.

[0069] Another object of the present invention is to provide an application method without electrical wiring, wherein the applicator has a certain degree of freedom of movement and can be used for work performed on a workbench, conveyor belt, product packaging line or any other process compatible with hot melt thermoplastic adhesives.

[0070] Another object of the present invention is to provide a portable thermal tool that can be used like a marker pen, with a wide range of degrees of freedom of movement.

[0071] The list of targets also includes generating rotary applicator nozzles to apply or transfer adhesive to various surfaces. The applicator nozzles have a pen-like physical form, a uniform width depending on the nozzle measurement, and a smooth or textured thickness depending on the model or design of the surface of each applicator nozzle.

[0072] The ultimate goal of this invention is to provide an applicator with a wide degree of freedom of movement and the ability to easily and precisely apply this type of thermal adhesive to desired locations manually. The thermal adhesive is composed of 100% solid binder and contains no unhealthy solvents. In industrial use, its advantages over conventional brushes include process efficiency and energy savings, flexible operating sequences, higher productivity per work hour or "per pick-up," greater precision and uniformity in adhesive application, and greater adhesive savings due to the ability to use applicator nozzles of varying widths and thicknesses. The product's technical, operational safety, material, and ergonomic features and solutions indicate its suitability for industrial environments, but also allow for versatility, such as in professional settings, homes, schools, etc. (via optional replaceable nozzles).

[0092] As the subject of this patent application, an industrial thermoplastic adhesive applicator includes a central heating and cooling control unit (1), on which a housing (2) is provided for a manual applicator (3) having an adhesive reservoir (3B). The central heating and cooling control unit (1) is designed to receive at least one manual applicator (3), and can receive two, three, four, or more applicators, all of which remain stationary. The heating and cooling control unit (1) is equipped with a display (4) for recording and evaluating heating data, and also has a general electrical switch (5) and a signal (6).

[0093] The heating and cooling control unit (1) actively cools the body by means of air circulation (9), collects heat energy from the heating bracket (7) using the heat energy storage of the manual applicator (3), and cools the body cover (8).

[0094] The heating system of the manual applicator (3) is made by electromagnetic induction, resistance (10) or other means, depending on its intended use.

[0095] The manual applicator (3) is provided with an insulated handle body (11) which is separate from the internal heating area (12). A collar (13) that receives the applicator tip (14) itself protrudes from the internal heating area (12). In the collar (13), the support (15) of the applicator tip (14) is threaded, which may be cylindrical, spherical or other form that allows it to roll like a pen for the transfer of thermoplastic adhesives.

[0096] The manual applicator (3) includes fins and an internal guide system (16) for heat insulation and cooling of the external treatment surface or the insulated handle body (11), induced by an air circulation system (9).

[0097] A key feature of this invention is that the system and technology for the thermal energy storage of a portable thermoplastic adhesive applicator are wireless.

[0098] The adhesive applicator roller, or applicator tip (14), preferably has a two-part structure, which includes a mirrored component (17) mounted on the adhesive transfer roller (14A). These applicator tips (14) will include different designs, which obviously depend on the actual requirements.

[0099] like Figure 11 and Figure 11A As shown, Figure 11A The design shown illustrates a three-dimensional wedge geometry (18) between the transfer roller (14A) and the roller support formed by component (17). The components inside the nozzle are arranged according to... Figure 11A As it moves in all directions (19), its dynamic results are added to the wedge end shape (18A), resulting in the pumping or compression of the adhesive (20). Figure 11A In this way, the compressed adhesive is induced and anchored to the surface of the transfer roller (14A), resulting in a continuous and uniform application (21) regardless of the application speed. Figure 11A .

[0100] Region (22) - Figure 11A The isolation area of ​​the adhesive (20) is shown, in which Figure 11 Minimize the dimensional adjustment between the transfer roller (14A) and the roller support (23) so as to Figure 4The manual applicator (3) in the central heating control unit (1) Figure 4 The adhesive will remain flowing for the remainder of the time.

[0101] This can be achieved by generating a resistor such as RES1 installed in the central heating control unit (1). Figure 14 and Figure 16 ) and other power sources or electromagnetic inductors GI1 and L1 ( Figure 15 ), heat the hot melt adhesive applicator.

[0102] The heating control of these applicator nozzles is achieved through an electronic temperature thermal regulator RT1 with an electronic temperature feedback sensor. Figure 14 and Figure 16 To perform, for example, PT100 or J-type thermocouples, etc. TP1 (32) Figure 14 and Figure 16 ) or infrared STIR (31) Figure 15 ), and can also be achieved through a bimetallic thermal regulator or by using a gas or temperature-type temperature sensor (T) ( Figure 16 ).

[0103] Figure 14 , Figure 15 and Figure 16 The electronic circuitry shows or symbolizes the minimum requirements for protection and functional features, wherein the power supply uses a 3A fuse (24), a main switch CG1 (25), a fan V1 (26), an indicator light L1 (27), a temperature regulator RT1 (28) or a thermostat (T), and in the case of electromagnetic induction, an induction coil BL1 (30) is used.

[0104] The applicator is heated in the central heating control unit (1), wherein the applicator (3) is in a stationary state, and the heat energy storage of the applicator (3) collects the heat from the heating support (7). Figure 5 The heat energy in the air is circulated through the air (9) Figure 5 Active cooling caused by the applicator body (3) is used to cool the cover (8).

[0105] Considering the physical properties of the most commonly used products, the thermoplastic adhesive used, according to the compound, softens (liquefies) at temperatures above 100 degrees Celsius and may reach temperatures close to 300 degrees Celsius. Therefore, the adhesive must reach these temperatures within the applicator handle (3). Thus, the central heating control unit (1) needs to generate this temperature and transmit it to the applicator (3), according to... Figure 5 At position (29), the temperature will be redistributed to the adhesive internally. According to Figure 2The applicator must also retain this heat inside for a period of time equal to or greater than the time required for the adhesive to be dispensed or applied.

[0106] Meanwhile, the outer surface of the portable manual applicator handle (3) needs to be kept cool during use to ensure safe and comfortable handling. To maintain the heating of the internal heat storage tank of the manual applicator (3) and proper cooling of the outer surface of the handle or cover (8) of the manual applicator (3), the cover (8) has been fitted with longitudinal stripes (8A). Figure 5 The combination of thermal insulation materials is used to develop this.

[0107] according to Figure 5A The design ensures that the airflow cooling the cover (8) of the manual applicator (3) in a static state does not affect the temperature in the internal adhesive reservoir because the cover is made of a material with low thermal conductivity.

[0108] Because the adhesive application process does not involve electrical wires, it offers a wide range of freedom of movement and can be used for work on desktops, conveyor belts, product packaging lines, or any other process compatible with thermoplastic adhesives (hot melt adhesives).

[0109] Thermoplastic adhesives used in portable applicators can be in granular, rod-shaped, or pouch-shaped form. When applied to substrate surfaces to be bonded, such as leather, rubber, fabrics, synthetic laminates, paper and cardboard, wood, and metal, the applicator is developed to apply heat-activated adhesives via a rotating nozzle.

[0110] The manual applicator (3) is designed to apply thermoplastic adhesives in the form of a smooth pattern or textured trail, the trail being proportional to the design of the applicator nozzle or applicator tip (14). On the substrate to be bonded, the application can have a linear or curved pattern.

[0111] The product’s technical, safety, and ergonomic features and solutions indicate that it can be used in industrial applications, but with optional replaceable nozzles, it can be used for a variety of general purposes, such as home, study, laboratory, etc.
