Description

Technical Field

[0001] This utility model relates to a hot melt adhesive composite polyester flat tape layering bonding device, specifically a hot melt adhesive composite polyester flat tape layering bonding device, belonging to the technical field of tape processing equipment. Background Technology

[0002] Hot melt adhesive composite polyester flat tape is a flat tape made of polyester as the base material and bonded by hot melt adhesive. It uses the adhesive properties of hot melt adhesive to achieve the composite of polyester materials. It has the characteristics of flat structure and tight bonding. It is suitable for a variety of scenarios that require stable connection and transmission, and can meet the relevant usage requirements with its material properties.

[0003] The prior art patent application number is 202122130647.4, entitled "An Optical Adhesive Multilayer Lamination Device," which includes a main structure. The main structure includes a supporting base plate and a feeding rack vertically arranged on the upper surface of the supporting base plate. The upper surface of the supporting base plate is also provided with a lamination mechanism and a winding mechanism. The feeding rack includes feeding components, and each feeding component is provided with an anti-deviation component in its feeding direction. The lamination mechanism includes a first support frame, and a support plate is horizontally installed at the top of the first support frame. The first support frame has a movable groove, and a movable plate is movably arranged in the movable groove. An upper heating tube and an upper adhesive roller sleeved on the upper heating tube are installed on the movable plate.

[0004] However, it relies on rotating the threaded rod to change the distance between the upper and lower rubber rollers. The whole operation process is quite cumbersome. It requires gradual adjustment by rotating the threaded rod. During the process, the adjustment accuracy can be controlled by real-time observation of the distance change. This not only consumes a lot of time and energy, but also makes it difficult to complete the precise adjustment in a short time. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a hot melt adhesive composite polyester flat tape layering bonding device to solve the above-mentioned problems. This addresses the issue that in the prior art, the adjustment process requires real-time observation of spacing changes to control the adjustment accuracy, which not only consumes a lot of time and effort but also makes it difficult to complete precise adjustments in a short time.

[0006] This utility model is achieved through the following technical solution: a hot melt adhesive composite polyester flat strip layer bonding device.

[0007] The system includes a mounting frame with through slots on both sides. A first motor is fixedly connected to one side of the mounting frame. Four mounting cylinders are fixedly connected to the top of the inner wall of the mounting frame. A return spring is fixedly connected to the top of the inner cavity of each mounting cylinder. A first repulsive magnet is fixedly connected to the bottom end of each return spring. The mounting frame provides stable support for each component. The through slots facilitate the installation and operation of components such as the motor. The combination of the return spring and the repulsive magnet provides elasticity and buffering force for subsequent structural adjustments. A pressure rod is inserted into the bottom end of each mounting cylinder. Four mounting plates are fixedly connected to the outer side of each mounting cylinder.

[0008] Preferably, the top end of the pressure rod penetrates the mounting cylinder and extends into the inner cavity of the mounting cylinder, and a second repulsive magnet is fixedly connected to the top end of the pressure rod. The insertion and connection between the pressure rod and the mounting cylinder ensures the stability of the structure, and the repulsive force between the repulsive magnets can assist in the flexible adjustment of the pressure rod, making it easy to control the position of the pressure rod.

[0009] Preferably, a fixing frame is fixedly connected to the bottom end of the pressure rod, and four friction sleeves are fixedly connected to one side of the fixing frame. The fixing frame connects the pressure rod and the friction sleeves as a whole. The friction sleeves can increase the friction with other components, improve the stability of the structure during operation, and prevent loosening.

[0010] Preferably, a friction rod is fixedly connected to the bottom of the mounting plate, the bottom end of the friction rod penetrates through the fixing frame, and the friction rod contacts the friction sleeve. The mounting plate provides stable support for the friction rod, and the friction force generated by the contact between the friction rod and the friction sleeve can effectively limit the arbitrary movement of the fixing frame and ensure the positional accuracy after structural adjustment.

[0011] Preferably, a mounting base is fixedly connected between the bottoms of the two fixed frames, and a second motor is fixedly connected to one side of one of the mounting bases. The second motor is located inside the through slot. The mounting base connects the two fixed frames, enhancing the stability of the overall structure. The through slot provides a reasonable installation space for the second motor, facilitating motor operation and heat dissipation.

[0012] Preferably, a rubber roller is rotatably connected between the inner sides of the two mounting seats and the mounting frame. The upper rubber roller is fixedly connected to the power output shaft of the second motor, and the lower rubber roller is fixedly connected to the power output shaft of the first motor. The rubber rollers achieve stable rotation through the mounting seats and the mounting frame. The two motors drive the upper and lower rubber rollers respectively, which can flexibly control the rotation speed and direction of the rubber rollers to meet different processing requirements.

[0013] Preferably, a heater is fixedly connected to one end of the rubber roller, and a heating tube is fixedly connected to one side of the heater. The heating tube extends into the inner cavity of the rubber roller, and the heat generated by the heater is transferred to the inner cavity of the rubber roller through the heating tube to realize the heating function of the rubber roller. This facilitates the heating treatment of materials during the processing of the rubber roller and improves the processing quality.

[0014] Preferably, a connecting frame is fixedly connected to the outer side of the heating tube, a fixing rod is fixedly connected to one side of the connecting frame, and a heat-conducting ring is fixedly connected to the outer side of the fixing rod. The heat-conducting rings are arranged in sequence, and the outer side of the heat-conducting rings extends into the interior of the rubber roller. The connecting frame and the fixing rod fix the heat-conducting rings to the outer side of the heating tube. The multiple heat-conducting rings arranged in sequence increase the contact area with the interior of the rubber roller, which can transfer heat to the rubber roller more evenly and improve the heating uniformity.

[0015] Preferably, a corrugated heat-conducting strip is fixedly connected to the outer side of the heat-conducting ring, and the corrugated heat-conducting strip is evenly distributed. The outer side of the corrugated heat-conducting strip extends into the interior of the rubber roller. The corrugated heat-conducting strip increases the contact area between the heat-conducting structure and the interior of the rubber roller. The evenly distributed design further improves the uniformity of heat transfer. At the same time, the corrugated shape can enhance the heat conduction efficiency, making the rubber roller heat up faster and more evenly.

[0016] This utility model provides a hot melt adhesive composite polyester flat tape layering bonding device, which has the following beneficial effects: 1. This hot melt adhesive composite polyester flat tape layering bonding device, through an adaptive spacing adjustment mechanism, can automatically adjust the spacing between the upper and lower adhesive rollers according to the thickness of the polyester flat tape. This effectively avoids bonding deviations caused by untimely or inaccurate manual adjustments, ensuring that polyester flat tapes of different thicknesses can be bonded evenly and tightly, thus improving the stability of bonding quality. At the same time, it eliminates tedious manual adjustment steps, reducing operating time and labor costs, improving the automation level and work efficiency of the device, and making the equipment more flexible in facing diverse production needs.

[0017] 2. This hot melt adhesive composite polyester flat tape layering and bonding device, through a uniform heating mechanism, ensures that the temperature of all parts of the adhesive roller remains consistent. A stable and uniform temperature environment guarantees that the hot melt adhesive melts fully and distributes evenly during the bonding process, preventing aging and deterioration of the hot melt adhesive due to excessively high local temperatures, or insufficient adhesion due to excessively low local temperatures, thus affecting the bonding effect. Furthermore, uniform heating reduces deformation and wrinkles caused by uneven heating of the polyester flat tape, ensuring the physical properties and appearance quality of the polyester flat tape, further improving the overall layering and bonding effect, and providing a reliable guarantee for subsequent use.

[0019] This utility model provides a hot melt adhesive composite polyester flat tape layering bonding device.

[0020] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 The device includes a mounting bracket 1, with through slots 101 on both sides. A first motor 102 is fixedly connected to one side of the mounting bracket 1. Four mounting cylinders 2 are fixedly connected to the top of the inner wall of the mounting bracket 1. A reset spring 201 is fixedly connected to the top of the inner cavity of the mounting cylinder 2. A first repulsive magnet 202 is fixedly connected to the bottom end of the reset spring 201.

[0021] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A pressure rod 3 is inserted into the bottom end of the mounting cylinder 2. The top end of the pressure rod 3 passes through the mounting cylinder 2 and extends into the inner cavity of the mounting cylinder 2. A second repulsive magnet 301 is fixedly connected to the top end of the pressure rod 3. A fixing frame 4 is fixedly connected to the bottom end of the pressure rod 3. Four friction sleeves 401 are fixedly connected to one side of the fixing frame 4. Four mounting plates 5 are fixedly connected to the outside of the mounting cylinder 2. A friction rod 501 is fixedly connected to the bottom of the mounting plate 5. The bottom end of the friction rod 501 passes through the fixing frame 4 and is in contact with the friction sleeve 401.

[0022] The through slots 101 on both sides of the mounting bracket 1 provide space for the movement of related components. When the rubber roller 7 comes into contact with materials of different thicknesses, the material exerts an upward force on the rubber roller 7. This force is transmitted to the pressure rod 3 through the fixing bracket 4. The second repulsive magnet 301 at the top of the pressure rod 3 and the first repulsive magnet 202 at the top of the inner cavity of the mounting cylinder 2 repel each other, forming a repulsive force. At the same time, the return spring 201 is in a compressed state and generates a downward elastic force. When the material thickness increases, the upward force increases, pushing the pressure rod 3 upward. At this time, the distance between the first repulsive magnet 202 and the second repulsive magnet 301 decreases, the repulsive force increases, the return spring 201 is further compressed, and the elastic force also increases, until the upward force, repulsive force, and elastic force reach a new equilibrium. The balance is achieved, causing the upper rubber roller 7 to move upward, increasing the distance between it and the lower rubber roller 7 to accommodate thicker materials. Conversely, when the material thickness decreases, the upward force decreases. Under the combined action of the spring force of the return spring 201 and the repulsive force of the first repulsive magnet 202 and the second repulsive magnet 301, the pressure rod 3 moves downward, driving the upper rubber roller 7 to move downward, reducing the distance between it and the lower rubber roller 7. In addition, the friction rod 501 at the bottom of the mounting plate 5 contacts the friction sleeve 401 on the fixing frame 4. During the up-and-down movement of the fixing frame 4, friction is generated between the friction rod 501 and the friction sleeve 401, which can slow down the movement speed of the fixing frame 4, avoid impact caused by excessive movement, and make the distance adjustment process more stable.

[0023] Example 2, please refer to again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A mounting base 6 is fixedly connected between the bottoms of the two fixed brackets 4. A second motor 601 is fixedly connected to one side of one mounting base 6. The second motor 601 is located inside the through groove 101. Rubber rollers 7 are rotatably connected between the two mounting bases 6 and the inner side of the mounting bracket 1. The upper rubber roller 7 is fixedly connected to the power output shaft of the second motor 601, and the lower rubber roller 7 is fixedly connected to the power output shaft of the first motor 102. A heater 701 is fixedly connected to one end of the rubber roller 7, and an auxiliary heating element is fixedly connected to one side of the heater 701. A heat pipe 702 extends into the inner cavity of the rubber roller 7. A connecting frame 8 is fixedly connected to the outer side of the heat pipe 702. A fixing rod 801 is fixedly connected to one side of the connecting frame 8. A heat-conducting ring 802 is fixedly connected to the outer side of the fixing rod 801. The heat-conducting rings 802 are arranged in sequence and extend to the interior of the rubber roller 7. A corrugated heat-conducting strip 803 is fixedly connected to the outer side of the heat-conducting rings 802 and is evenly distributed. The outer side of the corrugated heat-conducting strip 803 extends to the interior of the rubber roller 7.

[0024] Heater 701 is fixed to one end of rubber roller 7. When heater 701 is working, it generates heat and transfers it to the heating tube 702 connected to it. Heating tube 702 acts as an intermediate heat transfer carrier, introducing heat into the inner cavity of rubber roller 7. A fixing rod 801 is fixedly connected to the outside of heating tube 702 through connecting bracket 8. Heat-conducting rings 802 on fixing rod 801 are arranged sequentially, and the outer side of heat-conducting rings 802 extends into the inside of rubber roller 7, enabling the heat from heating tube 702 to be transferred to different positions of rubber roller 7. At the same time, the heat-conducting rings 802... The corrugated heat-conducting strips 803 fixedly connected to the outer side are evenly distributed and extend into the interior of the rubber roller 7. The corrugated structure increases the contact area between the corrugated heat-conducting strips 803 and the interior of the rubber roller 7, so that heat can be transferred to all parts of the rubber roller 7 more fully and evenly. Driven by the first motor 102 and the second motor 601, the upper and lower rubber rollers 7 rotate. As the rubber roller 7 rotates, the surface of the rubber roller 7, which has been heated evenly, can fully contact the material, thereby heating the material evenly and ensuring the consistency of the heating effect.

[0025] Working principle: The through slots 101 on both sides of the mounting frame 1 provide space for the movement of related components. When the rubber roller 7 comes into contact with materials of different thicknesses, the material exerts an upward force on the rubber roller 7. This force is transmitted to the pressure rod 3 through the fixing frame 4. The second repulsive magnet 301 at the top of the pressure rod 3 and the first repulsive magnet 202 at the top of the inner cavity of the mounting cylinder 2 repel each other, forming a repulsive force. At the same time, the return spring 201 is in a compressed state and generates a downward elastic force. When the material thickness increases, the upward force increases, pushing the pressure rod 3 upward. At this time, the distance between the first repulsive magnet 202 and the second repulsive magnet 301 decreases, the repulsive force increases, and the return spring 201 is compressed .... The spring 201 is further compressed, and the elastic force increases accordingly until the upward force, repulsive force, and elastic force reach a new balance. This causes the upper rubber roller 7 to move upward, increasing the distance between it and the lower rubber roller 7 to accommodate thicker materials. Conversely, when the material thickness decreases, the upward force decreases. Under the combined action of the spring force of the return spring 201 and the repulsive forces of the first repulsive magnet 202 and the second repulsive magnet 301, the pressure rod 3 moves downward, causing the upper rubber roller 7 to move downward, reducing the distance between it and the lower rubber roller 7. In addition, the friction rod 501 at the bottom of the mounting plate 5 contacts the friction sleeve 401 on the fixing frame 4. During the up-and-down movement, friction is generated between the friction rod 501 and the friction sleeve 401, which slows down the movement speed of the fixed frame 4, avoids impact caused by excessive movement, and makes the spacing adjustment process smoother. The heater 701 is fixed to one end of the rubber roller 7. When the heater 701 works, it generates heat and transfers it to the heating tube 702 connected to it. The heating tube 702 acts as an intermediate carrier for heat transfer, introducing heat into the inner cavity of the rubber roller 7. A fixed rod 801 is fixedly connected to the outside of the heating tube 702 through the connecting frame 8. The heat-conducting rings 802 on the fixed rod 801 are arranged in sequence, and the outer side of the heat-conducting rings 802 extends to the rubber roller 7. Inside, the heat from the heating tube 702 can be transferred to different positions of the rubber roller 7. At the same time, the corrugated heat-conducting strips 803 fixedly connected to the outside of the heat-conducting ring 802 are evenly distributed and extend into the inside of the rubber roller 7. The corrugated structure increases the contact area between the corrugated heat-conducting strips 803 and the inside of the rubber roller 7, so that the heat can be transferred to all parts of the rubber roller 7 more fully and evenly. Driven by the first motor 102 and the second motor 601, the upper and lower rubber rollers 7 rotate. As the rubber roller 7 rotates, the surface of the rubber roller 7, which has been heated evenly, can fully contact the material, thereby heating the material evenly and ensuring the consistency of the heating effect.

[0026] It should be noted that the model number of heater 701 is HSC2020. Heating element 702 model: GDR10150, power 300-800W, voltage 220V, material is seamless stainless steel tube, internally filled with magnesium oxide powder for insulation and heat conduction.

[0027] Heater 701 is a cartridge heater, and its core principle is resistance heating, which converts electrical energy into heat energy. The heating element is made of a high-resistance alloy wire (such as nickel-chromium alloy), and the two ends of the alloy wire are connected to the power supply through leads.

[0028] When powered on, the alloy wire generates Joule heat due to the resistance effect, and the heat is quickly conducted through the metal shell (stainless steel 304) to the heating tube 702 in contact with it.

[0029] The outer shell is tightly fitted to the heating tube 702 to ensure efficient heat transfer. At the same time, the outer shell has high temperature resistance and corrosion resistance properties, which can adapt to the working environment of the rubber roller 7.

[0030] Heating element 702 is a single-ended heating pipe, serving as an intermediate carrier for heat transfer. Its working principle is as follows: After receiving the heat conducted by heater 701, the heat is diffused to the entire tube body through the seamless stainless steel tube wall.

[0031] The magnesium oxide powder (MgO) filling the tube has high insulation and thermal conductivity, which can both isolate the internal heating wire from the outer metal tube and accelerate heat transfer.

[0032] The heat from the heating tube 702 is transferred to the heat-conducting ring 802 through the outer connecting frame 8 and the fixing rod 801, and finally evenly distributed to the inner cavity of the rubber roller 7 through the corrugated heat-conducting strip 803, so as to achieve overall heating of the rubber roller 7.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
