Description

Technical Field

[0001] This invention relates to the field of rubber products, and specifically to an apparatus and method for semi-automatic gluing and bonding of boot covers. Background Technology

[0002] In this era that emphasizes digital development, efficiency improvement, freeing up manual labor, and enhancing product quality, increasingly stringent requirements are being placed on products from top to bottom. We bear the responsibility of improving product quality and innovating processes, especially for adhesive tape products. Due to their "soft" characteristics, these products have a wide range of applications and have become integrated into all aspects of our lives and the equipment industry, such as being worn on personnel or in bullet casings. However, regardless of the industry in which they are applied, adhesive tape products ultimately require gluing and bonding to achieve their final form.

[0003] Currently, adhesive tape products are manufactured using traditional methods involving manual application of glue, drying, manual bonding, and pressing. This method has the following drawbacks: ① The glue application width is inconsistent, the glue application thickness is uneven, and the glue edges are unsightly; ② During the rolling process, the adhesive tape is rolled on a table manually using a hand roller. The table has been worn for many years and the surface is not completely flat. Therefore, air pressure may occur during the rolling process, resulting in the adhesive tape not being fully bonded and not sticking properly. In addition, the rolling pressure varies from person to person. ③Low production efficiency and high labor intensity; ④ Poor consistency in adhesive strength between adhesive tapes, etc.

[0004] The above phenomena pose risks to product quality and also create hidden dangers for users. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies by providing a device and method for semi-automatic gluing and bonding of boot covers. The method utilizes semi-automatic gluing and bonding equipment, replacing manual gluing, bonding, and pressing processes. Adhesive products formed using this method exhibit consistent gluing width and thickness, neat adhesive edges, consistent roller pressure, and no air pressure issues. Forming efficiency is significantly improved, and manual labor intensity is significantly reduced. This greatly improves product quality consistency and bonding strength stability, thereby enhancing product quality, customer satisfaction, and market competitiveness.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a device that can realize semi-automatic gluing and bonding of boot covers, including a semi-automatic gluing device and a semi-automatic bonding device; The semi-automatic glue coating equipment includes a glue coating worktable, on which a glue coating roller and a liftable pressure roller are installed. The pressure roller is connected to a gear transmission mechanism that drives its lifting and lowering. The glue coating worktable located below the glue coating roller is equipped with a glue coating thickness adjustment mechanism that drives part of the glue coating worktable to lift and lower. The glue coating roller is also connected to a glue coating width adjustment mechanism and a glue coating speed adjustment mechanism. The glue coating worktable is equipped with a glue storage box. An automatic circulating glue supply system is connected between the glue storage box and the glue coating roller. The glue coating width adjustment mechanism, the glue coating thickness adjustment mechanism, and the glue coating speed adjustment mechanism are all electrically connected to a controller. The control system switch of the controller is installed on the glue coating worktable. The semi-automatic bonding equipment includes a bonding worktable, on which a feeding mechanism and a pressing mechanism are installed. The feeding mechanism and the pressing mechanism are connected to a control system. The feeding wheel of the feeding mechanism and the pressing wheel of the pressing mechanism are respectively installed on the surface of the bonding worktable, with the pressing wheel located directly above the feeding wheel. The control system is divided into a pneumatic control system and an electrical control system. The pneumatic control system is used to adjust the roller pressure of the pressing wheel, and the electrical control system includes a speed control driver for controlling the rotational speed of the feeding wheel. Foot switches for both the pneumatic control system and the electrical control system are installed below the worktable. The pneumatic control valve of the pneumatic control system is installed on the bonding worktable, and an equipment switch is installed on the bonding worktable.

[0007] As a further limitation of the technical solution of the present invention, the automatic circulating glue supply system adopts an electric reducer to drive the screw mechanism to transport the glue from the glue storage box to the glue coating roller, and then overflows back into the glue storage box.

[0008] As a further limitation of the technical solution of the present invention, the width of the pressure roller is divided into different specifications of 10mm, 15mm, 20mm, 25mm and 30mm.

[0009] As a further limitation of the technical solution of the present invention, the adhesive width adjustment mechanism 3 is an adjustable baffle, and the adhesive roller is designed with a scale in front.

[0010] A method for semi-automatic gluing and bonding of boot covers, using the aforementioned apparatus, includes the following steps: S1. Turn on the control system switch. Adjust the coating speed using the coating speed adjustment mechanism, the coating thickness using the coating thickness adjustment mechanism, and the coating width using the coating width adjustment mechanism according to the thickness of the adhesive tape. Add adhesive to the storage box, ensuring that the adhesive does not exceed 4 / 5 of the storage box's volume. Raise the pressure roller. When the adhesive is evenly transferred to the coating roller, lower the pressure roller and place the tape to be coated under the coating roller, ensuring that the surface of the tape to be coated is in full contact with the coating roller. Finally, continuously and evenly transfer the adhesive from the coating roller to the tape, thus achieving semi-automatic coating. S2. Turn on the equipment switch 16, adjust the roller pressure through the pneumatic control valve, adjust the roller speed through the speed control driver, step on the foot switch of the pneumatic control system, manually place the adhesive-coated tape at the inlet of the feed roller, and press the tape to be pressed by the pressing roller of the pressing mechanism to press and position it. Then step on the foot switch of the electric control system to start the feeding mechanism. The motor reduction mechanism drives the feed roller and the pressing roller to realize the automatic and continuous feeding of the tape sheet. The pneumatic pressing mechanism presses the tape firmly to achieve semi-automatic pressing and bonding.

[0011] As a further limitation of the technical solution of the present invention, in step S1, the adhesive application speed is adjusted to 8-10 m / min and the adhesive application thickness is adjusted to 0.3-0.4 mm.

[0012] As a further limitation of the technical solution of the present invention, in step S2, the speed control driver adjusts the roller pressing speed to 1 to 1.5 m / min, and the pneumatic control valve adjusts the roller pressing pressure to 0.4 to 0.5 MPa.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses semi-automatic gluing and bonding equipment to replace manual gluing and bonding molding methods. The thickness and width of the glue are consistent, the glue edges are neat and beautiful, the bonding and pressing force is stable, and air pressure is avoided, thus improving the consistency of product quality.

[0014] 2. It is relatively easy to operate. The original manual method requires a lot of time. With the present invention, only the parameters need to be adjusted and manual assistance is required. The equipment can automatically apply glue and bond. Taking small boot cover products as an example, actual verification shows that the efficiency can be increased from the original (15~20) pairs / person·day to 25 pairs / person·day.

[0015] 3. The adhesive tape products formed by the equipment have been verified to have a stable bonding strength that has increased from (0.55~0.96) kN / m under manual operation to (0.88~0.93) kN / m.

[0016] 4. This equipment can be applied to various adhesive tape products, thus expanding its application scope. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. Example

[0021] A device for semi-automatic gluing and bonding of boot covers, comprising a semi-automatic gluing device and a semi-automatic bonding device; like Figure 1 As shown, the semi-automatic glue coating equipment includes a glue coating worktable. A glue coating roller 2 and a liftable pressure roller 1 are installed on the glue coating worktable. The pressure roller 1 is connected to a gear transmission mechanism 8 that drives its lifting and lowering (any existing gear transmission mechanism that enables the pressure roller 1 to lift and lower is acceptable). The glue coating worktable located below the glue coating roller 2 is equipped with a glue coating thickness adjustment mechanism 4 that drives part of the glue coating worktable to lift and lower. The glue coating roller 2 is also connected to a glue coating width adjustment mechanism 3 and a glue coating speed adjustment mechanism 6. The glue coating worktable is equipped with a glue storage box 7. An automatic circulating glue supply system is connected between the glue storage box 7 and the glue coating roller 2. The glue coating width adjustment mechanism 3, the glue coating thickness adjustment mechanism 4, and the glue coating speed adjustment mechanism 6 are all electrically connected to a controller. The control system switch 5 of the controller is installed on the glue coating worktable. The semi-automatic glue coating equipment is constructed entirely of high-strength aluminum alloy, boasting high strength, lightweight, excellent electrical conductivity, superior processing performance, and outstanding resistance to high and low temperatures, allowing operation in environments ranging from -100℃ to 100℃. The glue storage box 7 is suitable for natural rubber, neoprene rubber, and other types of adhesives; it is independently detachable for easy cleaning. The automatic circulating glue supply system utilizes an electric reducer-driven screw mechanism to transport the glue from the storage box 7 to the coating roller, then overflows back into the storage box, continuously circulating and simultaneously agitating the glue to prevent sedimentation and solidification. The glue coating system consists of a coating roller, a pressure roller, an electric reducer, and a gear transmission system. The pressure roller 1 comes in different widths of 10mm, 15mm, 20mm, 25mm, and 30mm to suit various adhesive fabrics. The coating roller 2 features a graduated scale at the front, allowing for flexible adjustment of the baffle as needed. The adjustment mechanism includes a coating speed adjustment mechanism 6, a coating thickness adjustment mechanism 4, and a coating width adjustment mechanism 3, digitally displaying parameters such as speed and thickness, offering simple operation and high precision. The control system consists of electrical components, speed control drivers, rotary switches, connecting cables, and control boxes.

[0022] In use, turn on the control system switch 5, adjust the coating speed to (8~10) m / min using the coating speed adjustment mechanism 6 according to the thickness of the adhesive tape, adjust the coating thickness to (0.3~0.4) mm using the coating thickness adjustment mechanism 4, adjust the coating width using the coating width adjustment mechanism 3, add an appropriate amount of adhesive paste (not exceeding 4 / 5 of the storage box volume) to the storage box 7, lift the pressure roller 1, and when the adhesive paste is evenly transferred to the coating roller 2, lower the pressure roller 1, place the adhesive tape to be coated under the coating roller 2, so that the surface of the adhesive tape to be coated is in full contact with the coating roller 2, and finally continuously and evenly transfer the adhesive paste on the coating roller 2 to the adhesive tape, thereby realizing semi-automatic coating.

[0023] like Figure 2 As shown, the semi-automatic bonding equipment includes a bonding worktable 9, on which a feeding mechanism and a pressing mechanism are installed. The feeding mechanism and the pressing mechanism are connected to a control system. The feeding wheel 10 of the feeding mechanism and the pressing wheel 11 of the pressing mechanism are respectively installed on the surface of the bonding worktable 9, with the pressing wheel 11 located directly above the feeding wheel 10. The control system is divided into a pneumatic control system and an electric control system. The pneumatic control system is used to adjust the roller pressure of the pressing wheel 11. The electric control system includes a speed control driver 12, which is used to control the rotational speed of the feeding wheel 10. A foot switch 13 for the pneumatic control system and a foot switch 14 for the electric control system are installed below the worktable 9. The pneumatic control valve 15 of the pneumatic control system is installed on the bonding worktable 9, and an equipment switch 16 is installed on the bonding worktable 9.

[0024] The semi-automatic bonding equipment also uses high-strength aluminum alloy to ensure the strength of the entire device; the bonding worktable 9 uses an anti-static panel, and the pressing mechanism consists of a pressing cylinder, a guide mechanism, a pressing wheel, and various connecting parts. The pressing wheel 11 is made of rubber, which can effectively prevent the adhesive material from being damaged and better ensure the appearance quality of the adhesive and the strength after bonding; the feeding mechanism consists of a motor reduction mechanism, a synchronous belt drive mechanism, a feeding wheel, and various connecting parts; the control system is divided into a pneumatic control system (composed of an air source treatment device, air control valve, foot switch, connecting pipes, etc.) and an electrical control system (composed of electrical components, speed control driver, foot switch, connecting cable, control box, etc.).

[0025] In use, turn on the equipment switch 16, adjust the roller pressure to (0.4~0.5) MPa through the pneumatic control valve 15, adjust the roller speed to (1~1.5) m / min through the speed control driver 12, step on the foot switch 4 of the pneumatic control system, manually place the adhesive-coated tape at the inlet of the feed wheel 10 of the feeding mechanism, press and position the tape to be pressed by the pressing wheel 11 of the pressing mechanism, then step on the foot switch 14 of the electric control system to start the feeding mechanism. The motor reduction mechanism drives the feed wheel 10 and the pressing wheel 11 to realize the automatic continuous feeding of the tape sheet. The pneumatic pressing mechanism presses the tape firmly to achieve semi-automatic pressing and bonding.

[0026] This invention is designed with the concept of "improving product quality consistency and freeing up manual labor." It utilizes equipment to replace manual operation, and employs adhesive tape products (mainly boot covers) for process testing to ultimately determine the equipment's coating speed, coating width, roller speed, and roller pressure parameters. This significantly improves molding efficiency, enabling more timely delivery; reduces labor costs and intensity, creating considerable economic benefits; and enhances adhesive strength stability. This improves product quality, enhancing market competitiveness, and reduces after-sales risks during actual use, thereby increasing user satisfaction.

[0027] Traditional manual glue application and bonding methods for forming adhesive tape products can lead to problems such as inconsistent glue thickness, roller pressure, unstable bonding strength, low efficiency, and product quality risks. This invention uses semi-automatic glue application and bonding equipment to replace manual forming methods, which can ensure consistent glue thickness and width, neat and beautiful glue edges, stable bonding pressure, and avoid air pressure. The bonding strength can be stably improved from (0.55~0.96) kN / m under manual operation to (0.88~0.93) kN / m, thus improving the consistency of product quality.

[0028] This invention is relatively easy to operate. With only parameter adjustments and manual assistance, the equipment can automatically apply glue and bond the product. Taking small boot covers as an example, actual verification shows that the efficiency can be increased from the original (15-20) pairs / person / day to 25 pairs / person / day. The improved molding efficiency allows for more timely delivery, reduces labor costs and intensity, and creates considerable economic benefits; the bonding strength and stability are also improved.
