Description

Technical Field

[0001] This utility model relates to the field of inflatable surfboard production technology, and in particular to a high-temperature hot-melt device for inflatable surfboards. Background Technology

[0002] In the prior art, such as the patent with patent publication number CN215359947U, the disclosed roller sealing device for inflatable surfboards, through the design of a specific connection relationship between the first roller, the second roller, the worktable, and the heating device, is particularly suitable for bonding the curved parts of the surface layer of inflatable surfboards, replacing the traditional method of repeatedly scraping glue by hand with a scraper. Specifically for bonding the curved parts of the surface layer of inflatable surfboards, the height adjustment mechanism can adjust the appropriate distance between the first roller and the second roller as needed, so that the glued bonding part can pass smoothly through the gap between the first roller and the second roller, and the effect of pressing and sealing the edge can be achieved.

[0003] In the process of realizing this utility model, the inventors discovered the following problems in the prior art:

[0004] In existing technologies, glue needs to be applied to the edge of the surfboard surface layer, and the surfboard surface layer and the edge sealing strip are pressed together by a roller edge sealer. This requires applying glue first and then pressing, which requires a large amount of glue. The glue is prone to producing an unpleasant odor, resulting in low production efficiency. Utility Model Content

[0005] In view of the above problems, this application provides a high-temperature hot-melt equipment for inflatable surfboards to solve the technical problems of existing technologies, which require applying glue before pressing, require a large amount of glue, and the glue is prone to producing an unpleasant odor, resulting in low production efficiency.

[0006] To achieve the above objectives, in a first aspect, this application provides a high-temperature hot-melt device for inflatable surfboards, comprising:

[0007] frame;

[0008] A material guiding mechanism is mounted on the machine frame. The material guiding mechanism includes a material guiding roller and a folding assembly. The material guiding roller and the folding assembly are arranged sequentially along the production direction. The folding assembly is used to fold the first layer of mesh fabric.

[0009] A positioning mechanism is provided behind the production direction of the hemming assembly, and the positioning mechanism is used to position the first layer of mesh fabric.

[0010] A heating device, wherein the heating device is used to heat the area between the surface layer of the material to be melted and the first layer of mesh fabric; and

[0011] A hot melt driving device includes a first roller, a second roller, a first lifting unit, and a driving unit. The first roller and the second roller are located behind the production direction of the positioning mechanism. The first roller is located above the second roller. The first lifting unit is used to drive the first roller to move closer to or away from the second roller. The driving unit is used to drive the first roller to rotate.

[0012] Unlike existing technologies, the technical solution of this application uses a material guiding mechanism mounted on the frame. This guiding mechanism includes a guide roller and a folding assembly, which are arranged sequentially along the production direction. The folding assembly is used to fold the first layer of mesh fabric. A positioning mechanism is located behind the folding assembly in the production direction, and is used to position the first layer of mesh fabric. A heating device is used to heat the surface layer of the material to be melted and the first layer of mesh fabric. A hot-melt driving device drives the first layer of mesh fabric forward. Thus, the material guiding mechanism is used to guide the first layer of mesh fabric... The fabric is exported, and the first layer of mesh fabric is folded to form a V-shaped structure. The first layer of mesh fabric is positioned by a positioning mechanism to maintain its V-shaped structure. The heating device heats the surface layer of the material to be melted and the first layer of mesh fabric. The hot melt drive device presses the surface layer of the material to be melted and the first layer of mesh fabric together, achieving hot melt fixation between the surface layer of the material to be melted and the first layer of mesh fabric. There is no need to apply glue to the surface layer of the material to be melted, and no glue is needed, avoiding irritating odors during production. The process of applying glue before pressing is changed to hot melt pressing, improving production efficiency.

[0013] In one embodiment of this utility model, the folding assembly includes a mounting rod, a fixing rod, a lower support rod, and an upper rotating rod. The mounting rod is mounted on the frame, the lower support rod and the upper rotating rod are mounted on the mounting rod, the upper rotating rod is hinged to the mounting rod, the lower support rod and the upper rotating rod are arranged in a V-shape, and the fixing rod is disposed at the V-shaped opening between the lower support rod and the upper rotating rod.

[0014] In this way, the lower support rod and the upper rotating rod form a V-shape, making the first layer of mesh fabric V-shaped. Then, the fixing rod is inserted between the first layer of mesh fabric to maintain the shape of the first layer of mesh fabric. The upper rotating rod is rotatably set on the other end of the mounting rod, which can fix the upper part of the first layer of mesh fabric and prevent the first layer of mesh fabric from moving.

[0015] In one embodiment of this utility model, the positioning mechanism includes an upper positioning part, a connecting part, and a lower positioning part. The upper positioning part is connected to the lower positioning part through the connecting part, and the upper positioning part, the connecting part, and the lower positioning part form a U-shaped structure.

[0016] In this way, the upper positioning part, the connecting part, and the lower positioning part form a U-shaped structure to position the first layer of mesh fabric entering between the first roller and the second roller, ensuring the position of the first layer of mesh fabric entering between the first roller and the second roller, and improving the accuracy of the high-temperature hot melt equipment.

[0017] In one embodiment of this utility model, the heating device includes a moving mechanism and a heating head. The moving mechanism is convexly connected to the heating head. The moving mechanism is used to move the heating head between the surface layer of the material to be melted and the first layer of mesh fabric. The heating head is used to heat the surface layer of the material to be melted and the first layer of mesh fabric.

[0018] Thus, the heating head heats the surface layer of the material to be melted and the first layer of mesh fabric, so that the surface layer of the material to be melted and the first layer of mesh fabric reach the conditions for high-temperature heat melting. Then, the first roller and the second roller press together to achieve heat melting and fixation between the surface layer of the material to be melted and the first layer of mesh fabric.

[0019] In one embodiment of this utility model, the moving mechanism includes a second lifting unit and a translation unit. The second lifting unit is used to drive the heating head to rise and fall, and the translation unit is used to drive the heating head to move in the horizontal direction.

[0020] Thus, the second lifting unit is used to drive the heating head to rise and fall, and the translation unit is used to drive the heating head to move in the horizontal direction, so that the heating head can heat the surface layer of the material to be melted and the first layer of mesh fabric.

[0021] In one embodiment of this utility model, the heating device includes two heating heads arranged horizontally, both of which are positioned between the first roller and the second roller.

[0022] Thus, by arranging the two heating heads horizontally, the contact area between the first roller and the second roller is relatively increased, which can increase the heating width of the heating device, expand the area of ​​the surface layer of the material to be melted and the first layer of mesh fabric to be melted, and expand the connection area between the surface layer of the material to be melted and the first layer of mesh fabric.

[0023] In one embodiment of this utility model, the material guiding mechanism includes a feeding roller, a first guiding roller, and a second guiding roller. The feeding roller is used to feed the first layer of mesh fabric. The first layer of mesh fabric passes through the first guiding roller, the second guiding roller, the folding assembly, and the positioning mechanism in sequence and enters between the first roller body and the second roller body.

[0024] In this way, the first layer of mesh fabric is fed by the feeding roller, guided by the first and second guide rollers, folded by the folding assembly, and positioned by the positioning mechanism. Finally, it is fed between the first and second rollers for heat melting, thus realizing automated feeding of the first layer of mesh fabric and improving production efficiency.

[0025] As one embodiment of this utility model, the high-temperature hot-melt equipment for inflatable surfboards further includes a sensor and a controller. The sensor is positioned relative to the first guide roller and the second guide roller. The sensor is electrically connected to the controller and sends data to the controller. The controller controls the heating device based on the data sent by the sensor.

[0026] In this way, the sensor can monitor whether there is material between the first guide roller and the second guide roller, and then start the heating device to avoid heating when there is no material. At the same time, the sensor can detect whether a hand is put between the first guide roller and the second guide roller to prevent the first guide roller and the second guide roller from pinching or burning the hand.

[0027] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0057] In existing technologies, glue needs to be applied to the edge of the surfboard surface layer, and the surfboard surface layer and the edge sealing strip are pressed together by a roller edge sealer. This requires applying glue first and then pressing, which requires a large amount of glue. The glue is prone to producing an unpleasant odor, resulting in low production efficiency.

[0058] In view of this, this application provides a high-temperature hot-melt equipment for inflatable surfboards, including a frame 1, a material guiding mechanism 2, a positioning mechanism 3, a heating device 4, and a hot-melt driving device 5. The material guiding mechanism 2 is mounted on the frame 1 and includes a material guiding roller and a folding assembly 22. The material guiding roller and the folding assembly 22 are arranged sequentially along the production direction. The folding assembly 22 is used to fold the first layer of mesh fabric 8. The positioning mechanism 3 is located behind the folding assembly 22 in the production direction and is used to position the first layer of mesh fabric 8. The heating device 4 is used to heat the surface layer 9 of the material to be hot-melted and the first layer of mesh fabric 8. The hot-melt driving device 5 includes a first roller 51, a second roller 52, a first lifting unit, and a driving unit 54. The first roller 51 and the second roller 52 are located behind the positioning mechanism 3 in the production direction. The first roller 51 is located above the second roller 52. The first lifting unit is used to drive the first roller 51 to move closer to or away from the second roller 52. The driving unit 54 is used to drive the first roller 51 to rotate. The hot melt drive device 5 presses the surface layer 9 of the material to be hot melted and the first layer of mesh fabric 8 together, thereby achieving hot melt fixation between the surface layer 9 of the material to be hot melted and the first layer of mesh fabric 8. There is no need to apply glue to the surface layer 9 of the material to be hot melted, and no glue is needed, thus avoiding irritating odors during production. The process of applying glue before pressing is changed to hot melt pressing, which improves production efficiency.

[0059] According to some embodiments of this application, please refer to Figures 1 to 7 This embodiment relates to a high-temperature hot-melt equipment for inflatable surfboards, including a frame 1, a material guiding mechanism 2, a positioning mechanism 3, a heating device 4, and a hot-melt driving device 5. The material guiding mechanism 2 is mounted on the frame 1 and includes a material guiding roller and a folding assembly 22. The material guiding roller and the folding assembly 22 are arranged sequentially along the production direction. The folding assembly 22 is used to fold the first layer of mesh fabric 8. The positioning mechanism 3 is located behind the folding assembly 22 in the production direction and is used to position the first layer of mesh fabric 8. The heating device 4 is used to heat the surface layer 9 of the material to be hot-melted and the first layer of mesh fabric 8. The hot-melt driving device 5 includes a first roller 51, a second roller 52, a first lifting unit, and a driving unit 54. The first roller 51 and the second roller 52 are located behind the positioning mechanism 3 in the production direction. The first roller 51 is located above the second roller 52. The first lifting unit is used to drive the first roller 51 to move closer to or away from the second roller 52. The driving unit 54 is used to drive the first roller 51 to rotate.

[0060] In some embodiments, the frame 1 serves as a base for other components;

[0061] In some embodiments, the material guiding mechanism 2 is used to discharge the first layer of mesh fabric 8 and make the first layer of mesh fabric 8 into a U-shaped structure, entering between the first roller body 51 and the second roller body 52;

[0062] In other embodiments, the surface layer 9 of the material to be heat-fused can be fed manually or by a feeding mechanism; in some embodiments, the surface layer 9 of the material to be heat-fused can be the surface layer of an inflatable surfboard, which has two layers, upper and lower, and is made of a wire mesh fabric. The first layer of mesh fabric 8 can be heat-fused onto the upper layer of the inflatable surfboard; the surface layer 9 of the material to be heat-fused can also be a second layer of mesh fabric, where the first layer of mesh fabric 8 is heat-fused and fixed onto the second layer of mesh fabric, and the first layer of mesh fabric 8 and the second layer of mesh fabric are then heat-fused together onto the upper layer of the wire mesh fabric of the inflatable surfboard.

[0063] In some embodiments, the positioning mechanism 3 positions the first layer of mesh fabric 8 to ensure that the first layer of mesh fabric 8 has a U-shaped structure and enters between the first roller 51 and the second roller 52;

[0064] In some embodiments, the heating device 4 heats the inner side of the first layer of mesh fabric 8 and / or the upper surface of the material surface layer 9 to be heat-melted, so that the first layer of mesh fabric 8 and the material surface layer 9 to be heat-melted can be fixed together.

[0065] In some embodiments, the hot melt drive device 5 drives the first roller 51 and the second roller 52 to approach each other and press the first layer of mesh fabric 8 and the surface layer 9 of the material to be hot melted together; at the same time, it drives the first roller 51 to rotate, which drives the first layer of mesh fabric 8 and the surface layer 9 of the material to be hot melted to move forward. The structure and principle of the hot melt drive device 5 are conventional technical means, and the specific structure and principle will not be described in detail here.

[0066] In some embodiments, the inflatable surfboard is made of wire mesh fabric, specifically wire mesh fabric produced by Fujian Sijia Environmental Protection Materials Technology Co., Ltd. Wire mesh fabric generally refers to polyester fiber spatial structure wire mesh industrial fabric, whose structure mainly includes a base layer, a wire layer, and a functional layer. The upper and lower base layers are typically made of warp-knitted or plain-woven fabric. These two layers provide basic support and protection, offering fundamental strength and stability to the entire mesh fabric. Evenly distributed dotted interlacing points connect with the intermediate wire layer, forming a unified whole. The intermediate wire layer, located between the upper and lower base layers, is a key structural component of the wire mesh fabric. The upper and lower functional layers are respectively located on the surface of the upper composite layer and the bottom surface of the lower composite layer. The lower functional layer typically includes a wear-resistant layer, a waterproof layer, a fire-resistant layer, and an antibacterial layer. The specific principle of the wire mesh fabric is a conventional technical solution, and the detailed principle will not be elaborated further.

[0067] In this embodiment, a material guiding mechanism 2 is mounted on the frame 1. The material guiding mechanism 2 includes a material guiding roller and a folding assembly 22. The material guiding roller and the folding assembly 22 are arranged sequentially along the production direction. The folding assembly 22 is used to fold the first layer of mesh fabric 8. A positioning mechanism 3 is located behind the folding assembly 22 in the production direction. The positioning mechanism 3 is used to position the first layer of mesh fabric 8. A heating device 4 is used to heat the surface layer 9 of the material to be melted and the first layer of mesh fabric 8. A hot melt driving device 5 drives the first layer of mesh fabric 8 to move forward.

[0068] Thus, the guiding mechanism 2 is used to guide the first layer of mesh fabric 8 out and fold the first layer of mesh fabric 8 to make the first layer of mesh fabric 8 into a V-shaped structure. The positioning mechanism 3 positions the first layer of mesh fabric 8 to maintain the V-shaped structure. The heating device 4 heats the surface layer 9 of the material to be melted and the first layer of mesh fabric 8. The hot melt driving device 5 presses the surface layer 9 of the material to be melted and the first layer of mesh fabric 8 together to achieve hot melt fixation between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8. There is no need to apply glue to the surface layer 9 of the material to be melted, and no glue is needed, avoiding the production of irritating odors. The process of applying glue before pressing is changed to hot melt pressing, which improves production efficiency.

[0069] According to some embodiments of this application, optionally, such as Figure 4 As shown, the folding assembly 22 includes a mounting rod 221, a fixing rod 222, a lower support rod 223, and an upper rotating rod 224. The mounting rod 221 is mounted on the frame 1. The lower support rod 223 and the upper rotating rod 224 are mounted on the mounting rod 221. The upper rotating rod 224 is hinged to the mounting rod 221. The lower support rod 223 and the upper rotating rod 224 are arranged in a V-shape. The fixing rod 222 is located at the V-shaped opening between the lower support rod 223 and the upper rotating rod 224.

[0070] The upper rotating rod 224 is hinged to the mounting rod 221 and can be pressed down to fix the upper half of the first layer of mesh fabric 8 to the fixing rod 222, and the lower half of the first layer of mesh fabric 8 to the lower support rod 223, so that the first layer of mesh fabric 8 has a V-shaped structure.

[0071] In this way, the lower support rod 223 and the upper rotating rod 224 form a V-shape, so that the first layer of mesh fabric 8 is V-shaped. Then, the shape of the first layer of mesh fabric 8 is maintained by inserting the fixing rod 222 between the first layer of mesh fabric 8. The upper rotating rod 224 is rotatably set on the other end of the mounting rod 221, which can fix the upper part of the first layer of mesh fabric 8 and prevent the first layer of mesh fabric 8 from moving.

[0072] According to some embodiments of this application, optionally, the positioning mechanism 3 includes an upper positioning part 31, a connecting part 32 and a lower positioning part 33. The upper positioning part 31 is connected to the lower positioning part 33 through the connecting part 32, and the upper positioning part 31, the connecting part 32 and the lower positioning part 33 form a U-shaped structure.

[0073] In other embodiments, the positioning mechanism 3 further includes a positioning rod 34. The left end of the upper positioning part 31 is provided with a lower limit part, and the left end of the lower positioning part 33 is provided with an upper limit part. The positioning rod 34 can be inserted into the U-shaped structure formed by the upper positioning part 31, the connecting part 32, and the lower positioning part 33 to support the first layer of mesh fabric 8. The positioning rod 34 and the upper positioning part 31, the connecting part 32, and the lower positioning part 33 form a channel through which the first layer of mesh fabric 8 passes, so as to ensure the shape and position of the first layer of mesh fabric 8.

[0074] Thus, the upper positioning part 31, the connecting part 32, and the lower positioning part 33 form a U-shaped structure to position the first layer of mesh fabric 8 that enters between the first roller body 51 and the second roller body 52, ensuring the position of the first layer of mesh fabric 8 that enters between the first roller body 51 and the second roller body 52, and improving the accuracy of the high-temperature hot melt equipment.

[0075] According to some embodiments of this application, optionally, the heating device 4 includes a moving mechanism 41 and a heating head 42. The moving mechanism 41 is connected to the heating head 42 in a transmission manner. The moving mechanism 41 is used to move the heating head 42 between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8. The heating head 42 is used to heat the surface layer 9 of the material to be melted and the first layer of mesh fabric 8.

[0076] The moving mechanism 41 is a conventional technical means that can drive the heating head 42 to be inserted between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8. The heating head 42 heats the upper surface of the surface layer 9 of the material to be melted and the upper inner surface of the first layer of mesh fabric 8 by contact, thereby connecting and fixing the upper surface of the surface layer 9 of the material to be melted and the upper inner surface of the first layer of mesh fabric 8.

[0077] Thus, the heating head 42 heats the surface layer 9 of the material to be melted and the first layer of mesh fabric 8, so that the surface layer 9 of the material to be melted and the first layer of mesh fabric 8 reach the conditions for high-temperature heat melting. Then, the first roller body 51 and the second roller body 52 press together to achieve heat melting and fixation between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8.

[0078] According to some embodiments of this application, optionally, the moving mechanism 41 includes a second lifting unit and a translation unit. The second lifting unit is used to drive the heating head 42 to rise and fall, and the translation unit is used to drive the heating head 42 to move in the horizontal direction.

[0079] Thus, the second lifting unit is used to drive the heating head 42 to rise and fall, and the translation unit is used to drive the heating head 42 to move in the horizontal direction, so that the heating head 42 can heat the surface layer 9 of the material to be melted and the first layer of mesh fabric 8.

[0080] According to some embodiments of this application, optionally, the heating device 4 includes two heating heads 42, which are arranged in a horizontal direction and both heating heads 42 are positioned between the first roller body 51 and the second roller body 52.

[0081] like Figure 6 As shown, the two heating heads 42 are arranged in the horizontal direction, which increases the heating area of ​​the two heating heads 42 in the horizontal direction and improves the connection stability between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8.

[0082] Thus, by arranging the two heating heads 42 in a horizontal direction, the contact area between the first roller 51 and the second roller 52 is relatively increased, which can increase the heating width of the heating device 4, expand the area of ​​the hot-melt material surface layer 9 and the first layer of mesh fabric 8, and expand the connection area between the hot-melt material surface layer 9 and the first layer of mesh fabric 8.

[0083] According to some embodiments of this application, optionally, the material guiding mechanism 2 includes a feeding roller 21, a first guiding roller 23 and a second guiding roller 24. The feeding roller 21 is used to feed the first layer of mesh fabric 8. The first layer of mesh fabric 8 passes through the first guiding roller 23, the second guiding roller 24, the folding assembly 22 and the positioning mechanism 3 in sequence and enters between the first roller body 51 and the second roller body 52.

[0084] like Figure 3 As shown, the first layer of mesh fabric 8 is released from the feeding roller 21 and passes through the first guide roller 23, the second guide roller 24, the folding assembly 22, and the positioning mechanism 3 in sequence before entering between the first roller body 51 and the second roller body 52.

[0085] Thus, the first layer of mesh fabric 8 is fed by the feeding roller 21, guided by the first guide roller 23 and the second guide roller 24, folded by the edge-folding assembly 22, and positioned by the positioning mechanism 3. Finally, it is fed between the first roller body 51 and the second roller body 52 for heat melting, thereby realizing automated feeding of the first layer of mesh fabric 8 and improving production efficiency.

[0086] According to some embodiments of this application, optionally, the high-temperature hot-melt device for inflatable surfboards also includes a sensor 6 and a controller 7. The sensor 6 is disposed relative to the first guide roller 23 and the second guide roller 24. The sensor 6 is electrically connected to the controller 7 and sends data to the controller 7. The controller 7 controls the heating device 4 according to the data sent by the sensor 6.

[0087] In some embodiments, sensor 6 can be a camera, which can monitor objects placed between the first guide roller 23 and the second guide roller 24 via video, preventing the heating device 4 from heating when there is no material, and also preventing human hands from entering between the first guide roller 23 and the second guide roller 24; the principle of sensor 6 is a conventional technical means, and the specific principle will not be described here.

[0088] Thus, the sensor 6 can monitor whether there is material between the first guide roller 23 and the second guide roller 24, and then start the heating device 4 to avoid heating when there is no material. At the same time, the sensor 6 can detect whether a hand is put between the first guide roller 23 and the second guide roller 24 to prevent the first guide roller 23 and the second guide roller 24 from pinching or burning the hand.

[0089] The process of using the high-temperature hot-melt equipment for inflatable surfboards is as follows:

[0090] like Figure 8 As shown, first, the first layer of mesh fabric 8 is fixed, and then the surface layer 9 of the material to be melted is placed between the first layer of mesh fabric 8. The heating head 42 of the heating device 4 enters between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8 for heating. The first guide roller 23 presses down and rotates, driving the surface layer 9 of the material to be melted and the first layer of mesh fabric 8 to move forward while moving and melting. During the melting process, the feeding direction of the surface layer 9 of the material to be melted is controlled. After sealing one circle, the heating head 42 is removed, the first guide roller 23 rises, and the surface layer 9 of the material to be melted and the first layer of mesh fabric 8 are released. The surface layer 9 of the material to be melted and the first layer of mesh fabric 8 are removed and the first layer of mesh fabric 8 is cut. The first layer of mesh fabric 8 without sealing is fixed by the fixing mechanism. The heating head 42 is inserted into the tail of the surface layer 9 of the material to be melted and the first layer of mesh fabric 8 to be finished, thus completing the fixing between the surface layer 9 of the material to be melted and the first layer of mesh fabric 8.

[0091] The heating head 42 can only heat-melt and fix the upper inner side of the first layer of mesh fabric 8 to the upper surface of the material to be heat-melted layer 9, but cannot heat-melt and fix the lower inner side of the first layer of mesh fabric 8 to the lower surface of the material to be heat-melted layer 9.
