Description

Technical Field

[0001] This utility model relates to the field of hot pressing equipment technology, specifically a hot pressing edge sealing device for sun-protective clothing fabric. Background Technology

[0002] In the production of sun-protective clothing, the quality of the edge-sealing process directly determines the product's waterproofness, the integrity of the sun-protective coating, and its lifespan. Traditional needle and thread sewing easily damages the thermoplastic structure of synthetic fiber fabrics, leading to edge unraveling and coating cracking. Conventional hot-press edge-sealing equipment generally suffers from problems such as "low positioning accuracy and poor heat-sealing synchronization." This results in either fabric waste due to misalignment of the pressing position or uneven edge-sealing strength due to asynchronous operation of the upper and lower heat-sealing mechanisms, making it difficult to meet the core requirements of sun-protective clothing for "high precision, high sealing performance, and low damage" in edge sealing.

[0003] For example, Chinese authorized patent CN218898625U discloses a hot-pressing edge-sealing device, including an operating table, a support table, and the hot-pressing edge-sealing device. The support table is installed on the operating table, and the hot-pressing edge-sealing device is installed on the operating table. The hot-pressing edge-sealing device includes a lifting structure, a push-out structure, and a receiving component. The lifting structure includes a lifting cylinder, a connecting seat, a pressing component, and a guide telescopic rod. This utility model relates to the field of zipper production technology and has the following beneficial effects: The lifting structure enables automated hot-pressing edge sealing, reducing labor costs, improving production efficiency, and saving time and effort; the push-out structure allows the hot-pressed zipper to be pushed out of the hot-pressing groove to a certain position, making it easy for workers to pick it up; the receiving component collects the adhesive flowing out from the hot-pressing edge, preventing the adhesive from flowing directly onto the operating table and saving cleaning time.

[0004] However, the aforementioned hot-press sealing device only drives the movement of a single hot-press component through its lifting structure, which cannot achieve synchronous opposing pressing of the upper and lower hot-pressing mechanisms and cannot guarantee consistent sealing strength. This device is prone to problems such as local over-tight pressing leading to fabric damage or local over-loose pressing leading to unsealed edges. Utility Model Content

[0021] 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.

[0022] like Figure 1 As shown, this embodiment provides a heat-sealing device for sun-protective clothing fabric, including: two sets of connecting frames 1, with two sets of transmission columns 101 rotatably mounted between the two sets of connecting frames 1; a conveyor belt 103 is fitted on the outer surface of the two sets of transmission columns 101, and a pressing groove 102 is formed on the outer surface of the conveyor belt 103; the pressing groove 102 can be driven to a position perpendicular to the heat-sealing mechanism 2 by the transmission column 101 rotating through the conveyor belt 103, and the heat-sealing mechanism 2 is fixedly mounted between the two sets of connecting frames 1.

[0023] The outer surface of both sets of transmission columns 101 is embedded with concave annular grooves in the middle section. The concave annular grooves can provide clearance space for multiple sets of equidistant reflectors 104 on the inner ring surface of the conveyor belt 103 as it is conveyed by the conveyor belt 103. During the transmission of the reflectors 104 with the conveyor belt 103, they can be perpendicular to the laser emitting end of the laser rangefinder 105. The laser rangefinder 105 is fixedly mounted in the crossbar 106, which is fixedly mounted between the two sets of connecting frames 1 and is located inside the conveyor belt 103. During the process of the conveyor belt 103 driving the reflectors 104 to be perpendicular to the laser emitting end of the laser rangefinder 105, the pressing groove 102 on the outer surface of the conveyor belt 103 is simultaneously driven to move to a position perpendicular to the heat sealing mechanism 2.

[0024] Through the design of the connecting frame 1, transmission column 101, pressing groove 102, conveyor belt 103, reflector 104, laser range sensor 105 and heat sealing mechanism 2, when heat sealing the edge of the sun protection clothing fabric, the sun protection clothing fabric to be sealed is first placed on the outer surface of the conveyor belt 103 and the part to be heat sealed is covered on the pressing groove 102. Then the sun protection clothing fabric can be moved by the conveyor belt 103. During the conveying process of the conveyor belt 103, multiple sets of reflectors 104 installed at equal intervals on its inner ring surface will move with the conveyor belt 103 until the conveyor belt 103 moves a certain reflector 104 to a position that is perpendicular to the laser emitting end of the laser range sensor 105. The laser range sensor 105 will detect the signal fed back by the reflector 104. At the same time, due to the synchronous transmission characteristics of the conveyor belt 103, the pressing groove 102 on its outer surface will also be driven to a position perpendicular to the heat sealing mechanism 2 fixedly installed between the two sets of connecting frames 1. At this time, the laser range sensor 105 transmits the positioning signal to the equipment control system, and the control system then controls the heat sealing mechanism 2 to start. The heat sealing mechanism 2 performs heat sealing operation on the edge of the sun protection clothing fabric in the pressing groove 102. After the sealing is completed, the transmission column 101 continues to drive the conveyor belt 103 to move, and transports the sun protection clothing fabric that has been sealed to the next process. At the same time, the conveyor belt 103 drives the next set of reflectors 104 to move to a position perpendicular to the laser range sensor 105, and then drives the next pressing groove 102 containing the fabric to be sealed to align with the heat sealing mechanism 2. This cycle realizes the continuous and precise heat sealing operation of the sun protection clothing fabric.

[0025] like Figure 2-Figure 3 As shown, the heat sealing mechanism 2 includes two sets of electric push rods 201, which are respectively fixedly mounted on one side of the two sets of connecting frames 1; a first linear heat sealing rod 203 is fixedly mounted between the upper surfaces of the piston rods of the two sets of electric push rods 201, and the first linear heat sealing rod 203 can be perpendicularly opposite to the pressing groove 102; a first toothed plate 202 is fixedly mounted on the lower surface of the piston rods of the two sets of electric push rods 201, and the first toothed plate 202 meshes with a gear 207; the gear 207 is rotatably mounted in an H-shaped frame 204, and the two sets of H-shaped frames 204 are respectively fixedly mounted on one inner end of the two sets of connecting frames 1; the other side of the two sets of H-shaped frames 204... A second toothed plate 206 is slidably mounted between the ends of a gear 207, and the second toothed plate 206 is located on the other side of the gear 207 and meshes with the gear 207; a second linear heat sealing rod 205 is fixedly mounted between the two sets of second toothed plates 206, the second linear heat sealing rod 205 is located inside the conveyor belt 103, and can slide out from the pressing groove 102 and touch the first linear heat sealing rod 203 and be perpendicular to it; the electric push rod 201 is controlled by a controller, and the signal receiving end of the controller is connected to the signal output end of the laser rangefinder 105; the laser rangefinder 105 is model HLM15, and the controller is model S7-200SMART.

[0026] Through the design of the electric push rod 201, the first toothed plate 202, the first linear heat-sealing rod 203, the H-shaped frame 204, the second linear heat-sealing rod 205, the second toothed plate 206, and the gear 207, when the conveyor belt 103 drives the reflector 104 to be perpendicular to the laser rangefinder 105, the laser rangefinder 105 will transmit the detection signal to the controller. The controller will then send an action command to the two sets of electric push rods 201. The two sets of electric push rods 201 will start on one side of the two sets of connecting frames 1, and their piston rods will begin to pull downwards. Since the first linear heat-sealing rod 203 is fixedly connected to the upper surface of the piston rods of the two sets of electric push rods 201, the piston rods... The movement synchronously drives the first linear heat-sealing rod 203 to move closer to the conveyor belt 103 until the first linear heat-sealing rod 203 is perpendicular to the pressing groove 102 on the outer surface of the conveyor belt 103 and approaches the fabric to be sealed. At the same time, the first toothed plate 202 fixed on the lower surface of the piston rod of the two sets of electric push rods 201 also moves synchronously with the piston rod. Because the first toothed plate 202 meshes with the gear 207 rotatably installed in the H-shaped frame 204, the movement of the first toothed plate 202 will drive the gear 207 to rotate in the H-shaped frame 204. Also, because the other side of the gear 207 meshes with the second toothed plate 206 slidably installed at the other end of the H-shaped frame 204, the teeth... The rotation of wheel 207 causes the second toothed plate 206 to move in the opposite direction to the first toothed plate 202. That is, when the first toothed plate 202 moves downward, the second toothed plate 206 moves upward. A second linear heat-sealing rod 205, located within the conveyor belt 103, is fixedly installed between the two sets of second toothed plates 206. The movement of the second toothed plate 206 causes the second linear heat-sealing rod 205 to slide upward from the pressing groove 102 of the conveyor belt 103, ultimately making precise contact with the downward-moving first linear heat-sealing rod 203. At this point, the edge of the sun-protective clothing fabric to be sealed is firmly clamped between the first linear heat-sealing rod 203 and the second linear heat-sealing rod 205. Simultaneously, heat is released to heat-press the edges of the fabric for sealing. This bidirectional pressing method ensures that the fabric fibers are fully heated and fused, avoiding incomplete sealing due to excessively loose pressing or fabric damage due to excessively tight pressing. This significantly improves the sealing strength and service life, meeting the waterproof and abrasion-resistant requirements of outdoor sun protection clothing. After the sealing operation is completed, the controller controls the piston rod of the electric push rod 201 to retract. Through the reverse linkage of the first toothed plate 202, gear 207 and the second toothed plate 206, the first linear heat sealing rod 203 is driven to reset upward and the second linear heat sealing rod 205 is retracted downward into the conveyor belt 103, preparing for the next sealing cycle.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: When heat-sealing the edge of the sun-protective clothing fabric, firstly, the sun-protective clothing fabric to be sealed is placed on the outer surface of the conveyor belt 103, and the part to be heat-sealed is covered above the pressing groove 102. Then, the sun-protective clothing fabric can be moved by the conveyor belt 103. During the conveying process of the conveyor belt 103, multiple sets of equidistantly installed reflectors 104 on its inner ring surface will move with the conveyor belt 103 until the conveyor belt 103 moves a certain reflector 104 to a position perpendicular to the laser emitting end of the laser range sensor 105. At this point, the laser range sensor 105 will transmit the detection signal to the control... The controller then sends an action command to the two sets of electric push rods 201. The two sets of electric push rods 201 are activated on one side of the two sets of connecting frames 1, and their piston rods begin to pull downward. Since the upper surface of the piston rods of the two sets of electric push rods 201 is fixedly connected to the first linear heat sealing rod 203, the movement of the piston rods will synchronously drive the first linear heat sealing rod 203 to move closer to the conveyor belt 103 until the first linear heat sealing rod 203 is perpendicular to the pressing groove 102 on the outer surface of the conveyor belt 103 and approaches the fabric to be sealed. At the same time, the first toothed plate 202 fixed to the lower surface of the piston rods of the two sets of electric push rods 201 also moves synchronously with the piston rods. The first toothed plate 202 meshes with a gear 207 rotatably mounted inside the H-shaped frame 204. The movement of the first toothed plate 202 drives the gear 207 to rotate within the H-shaped frame 204. Since the other side of the gear 207 meshes with a second toothed plate 206 slidably mounted at the other end of the H-shaped frame 204, the rotation of the gear 207 causes the second toothed plate 206 to move in the opposite direction to the first toothed plate 202. That is, when the first toothed plate 202 moves downwards, the second toothed plate 206 moves upwards. A second linear heat-sealing rod 205, located within the conveyor belt 103, is fixedly mounted between the two sets of second toothed plates 206. The movement of the second toothed plate 206 causes the second linear heat-sealing rod 205 to move from the conveyor belt 103. The fabric slides upward from the pressing groove 102 of the conveyor belt 103 and finally makes precise contact with the downward-moving first linear heat-sealing rod 203. At this time, the edge of the sun protection clothing fabric to be sealed is firmly clamped between the first linear heat-sealing rod 203 and the second linear heat-sealing rod 205. The two sets of heat-sealing rods release heat at the same time to heat-press and seal the edge of the fabric. After the sealing operation is completed, the controller controls the piston rod of the electric push rod 201 to retract. Through the reverse linkage of the first toothed plate 202, the gear 207 and the second toothed plate 206, the first linear heat-sealing rod 203 is driven to reset upward and the second linear heat-sealing rod 205 is retracted downward into the conveyor belt 103, preparing for the next sealing cycle.

[0028] Specifically, in this embodiment, both the first linear heat-sealing rod 203 and the second linear heat-sealing rod 205 have heating chambers inside, and electric heating tubes are fixedly installed inside the heating chambers. Temperature sensors are embedded in the side walls of both the first linear heat-sealing rod 203 and the second linear heat-sealing rod 205, and the detection end of the temperature sensor extends into the heating chamber. The outer side walls of both the first linear heat-sealing rod 203 and the second linear heat-sealing rod 205 have heat dissipation channels communicating with the heating chambers, and cooling fans are fixedly installed at the ports of the heat dissipation channels. The electric heating tubes, temperature sensors, and cooling fans are all electrically connected to the controller.

[0029] By adding electric heating elements and temperature sensors to the first linear heat-sealing rod 203 and the second linear heat-sealing rod 205, along with heat dissipation channels and cooling fans, precise temperature control of the heat-sealing rods can be achieved. The temperature sensor detects the temperature inside the heating chamber in real time and transmits the data to the controller. The controller adjusts the heating power of the electric heating elements according to the heat-sealing requirements of different materials such as polyester fiber and nylon in sun-protective clothing, ensuring that the temperature of the heat-sealing rod is stable within the optimal heat-sealing range for the appropriate fabric. This avoids problems such as fabric carbonization and coating damage due to excessively high temperatures, or insufficient fiber fusion and poor edge sealing due to excessively low temperatures. When the temperature exceeds the set threshold, the controller activates the cooling fan to quickly remove excess heat from the heating chamber through the heat dissipation channels, preventing the heat-sealing rod from aging due to overheating and extending its service life. At the same time, stable temperature control ensures the consistency of edge sealing quality for each piece of sun-protective clothing fabric in mass production, improves the product qualification rate, and meets the core requirements of sun-protective clothing for "high precision and high sealing performance" in edge sealing.

[0030] Specifically, in this embodiment, the inner wall of the pressing groove 102 is uniformly provided with annular anti-slip protrusions. The material of the annular anti-slip protrusions is high-temperature resistant silicone, and the outer surface of the annular anti-slip protrusions is flush with the groove opening of the pressing groove 102.

[0031] By setting high-temperature resistant silicone ring-shaped anti-slip protrusions on the inner wall of the pressing groove 102, when the sun protection clothing fabric covers the pressing groove 102, the ring-shaped anti-slip protrusions can make close contact with the lower surface of the fabric, increasing the friction between the fabric and the pressing groove 102. On the one hand, it can prevent the fabric from shifting due to inertia during the conveyor belt 103, ensuring that the edge sealing part of the fabric always accurately corresponds to the alignment position of the pressing groove 102 and the heat sealing mechanism 2, avoiding edge sealing misalignment. On the other hand, when the first straight heat sealing rod 203 and the second straight heat sealing rod 205 of the heat sealing mechanism 2 press against each other, the anti-slip protrusions can help fix the fabric, preventing the fabric from wrinkling or shifting during the heat pressing process, further ensuring the flatness and sealing of the edge sealing, and reducing the edge sealing scrap rate caused by fabric shifting.

[0032] In summary, this heat-sealing edge-sealing equipment for sun-protective clothing fabrics uses two sets of heat-sealing rods to form opposing synchronous pressing, which can apply uniform and stable pressure to the edges of the sun-protective clothing fabric. This bidirectional pressing method can ensure that the fabric fibers are fully heated and fused, avoiding unsealed edges due to excessively loose pressing in some areas, or fabric damage caused by excessively tight pressing in some areas. It significantly improves the edge-sealing strength and service life, meeting the waterproof and abrasion-resistant requirements of outdoor sun-protective clothing.
