Description

Technical Field

[0001] The utility model relates to the technical field of hot-pressing welding of waterproof and breathable membranes, in particular to a hot-pressing welding device for waterproof and breathable membranes. Background Art

[0002] A waterproof and breathable membrane is a versatile material that effectively blocks water penetration while allowing water vapor to pass through, providing excellent waterproofing and breathability. This material is commonly used in construction, outdoor clothing, footwear, and packaging to protect internal structures from moisture while maintaining dryness and comfort. A waterproof and breathable membrane hot-press welding device is used to combine waterproof and breathable membranes with other materials through a hot-press welding process. This device is commonly used in the automotive, electronics, and medical industries to create waterproof and breathable sealing structures.

[0003] For example, a hot-press welding device for a waterproof breathable membrane disclosed in Chinese patent CN209955337U is provided with two sets of limit blocks. When hot-press welding two waterproof breathable membranes, by turning the handle, the handle drives the second externally threaded rod to rotate inside the internally threaded barrel, so that the second externally threaded rod drives the limit block to move downward, causing the limit block to limit and fix the waterproof breathable membrane. In this way, the two waterproof breathable membranes are fixed more firmly during hot-press welding, and uneven welding at the connection is less likely to occur.

[0004] Although this structure can fix the waterproof breathable membrane, the device can only fix and clamp the membrane body, which is inconvenient to tighten the waterproof breathable membrane, resulting in wrinkles during hot pressing welding. Therefore, we propose a waterproof breathable membrane hot pressing welding device that can tighten and fix the waterproof breathable membrane to improve the hot pressing welding effect. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof breathable membrane hot pressing welding device to solve the problems raised in the above background technology.

[0007] Preferably, the tensioning assembly includes a first L-shaped plate fixedly mounted on the top surface of the processing table, a limit rod is slidingly provided inside the first L-shaped plate, a pressure plate is fixedly mounted on the end of the limit rod, the top surface of the pressure plate is rotatably connected to a screw, the outer wall of the screw is sleeved with a second L-shaped plate, a winding groove is opened on the top surface of the processing table, a rotating column is rotatably connected to the inner side of the winding groove, a roller is fixedly mounted on the end of the rotating column, a screw is sleeved on the outer wall of the roller, a splint is sleeved on the outer wall of the screw, a ratchet is fixedly sleeved on the outer wall of the rotating column, a clamping plate is hinged on the inner wall of the winding groove, a first spring is fixedly mounted on the top surface of the clamping plate, and a fixing plate is fixedly mounted on one end of the first spring away from the clamping plate.

[0008] Preferably, the cleaning assembly includes a fixed rod fixedly mounted on the top surface of the processing table, a second spring is sleeved on the outer wall of the fixed rod, a first ring is slidably mounted on the outer wall of the fixed rod, a sliding rod is fixedly mounted on the outer wall of the first ring, a second ring is slidably mounted on the outer wall of the sliding rod, and a cleaning strip is fixedly mounted on the outer wall of the second ring.

[0009] Preferably, the end of the card plate is slidably arranged with the outer wall of the ratchet, and the end of the card plate is arranged in an inclined surface. Under its restriction, the card plate contacts and engages with the card block on the outer wall of the ratchet to prevent the roller from rotating.

[0010] Preferably, the pressure plate is made of rubber material on the side away from the limit rod, and the second L-shaped plate is fixedly installed on the top surface of the processing table. The rubber pressure plate can avoid damaging the membrane by pressing. Under the restriction of the second L-shaped plate, the screw can be rotated to push the pressure plate connected to its end.

[0011] Preferably, the side of the cleaning strip away from the second ring is made of a flexible adsorption material, and the outer wall of the cleaning strip is arranged in an inclined surface. Under the restriction of the inclined surface, the cleaning strip sliding with the membrane body can avoid damaging the membrane body.

[0012] Preferably, one end of the second spring is fixedly installed on the top surface of the first ring, and the end of the second spring away from the first ring is fixedly installed on the end of the fixing rod away from the processing table. Under the elastic action of the second spring, the cleaning strip and the membrane body are fit and slid, and the membrane body can be easily passed from under the cleaning strip.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The waterproof breathable membrane hot-press welding device is composed of a tensioning component as one component. When the membrane needs to be hot-pressed and welded, one end of the tensioning component is placed at the bottom of the pressure plate, and the screw is rotated. Due to the sliding arrangement of the limit rod and the first L-shaped plate, the rotating screw pushes the pressure plate downward to clamp the end of the membrane. The other end of the membrane is placed between the clamping plate and the roller, and the screw is rotated to make the clamping plate press and clamp the membrane. At this time, the roller is rotated, which drives the rotating column fixed at the end to rotate accordingly, and the ratchet fixed on the outer wall of the rotating column rotates accordingly. The outer wall of the ratchet contacts and squeezes the card plate, and the card plate is squeezed. The hinge with the winding groove is the center of rotation and compresses the first spring. When the card plate is not squeezed by the ratchet, the card plate is pushed back to its original position under the elastic action of the first spring, and the rotating roller rolls up the film body tightly. When the film body is in a taut state, the roller no longer rotates, and the outer wall block of the ratchet contacts and engages with the end of the card plate to prevent the roller from rotating. Under the cooperation of the pressure plate and the roller winding, the film body is tightened so that wrinkles will not be generated during hot pressing, thereby improving the hot pressing welding effect (the processing table and hot pressing welding mechanism are existing public technologies in the comparative documents, so their structure is not fully described in this case).

[0015] 2. The waterproof and breathable membrane hot-pressing welding device is composed of a cleaning component as one of its components. When the membrane body needs to be hot-pressed and welded, it is tightly clamped and its surface needs to be cleaned to prevent debris from being hot-pressed into the inside of the membrane body. Under the elastic action of the second spring, the first ring is pushed downward, so that the first ring drives the slide bar to move downward, and the second ring sliding on the outer wall of the slide bar drives the cleaning bar to move downward, so that the cleaning bar contacts and presses with the surface of the membrane body. At this time, the cleaning bar is pulled to make the second ring fixed on the top surface of the cleaning bar slide on the outer wall of the slide bar to clean the dust attached to the outer wall of the membrane body. This structure can ensure that there is no impurity on the surface of the membrane body before hot-pressing and welding, so as to improve the hot-pressing welding effect.

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of a waterproof breathable membrane hot pressing welding device provided by the present invention is as follows Figures 1 to 6 Shown: A waterproof breathable membrane hot pressing welding device, comprising a processing table 1;

[0025] A hot pressing welding mechanism 2 is fixedly installed on the top surface of the processing table 1;

[0026] A membrane body 3 is provided below the hot pressing welding mechanism 2;

[0027] And a processing assembly 4 arranged below the hot pressing welding mechanism 2, the processing assembly 4 includes a tensioning assembly 41 arranged below the hot pressing welding mechanism 2, the tensioning assembly 41 includes a first L-shaped plate 411 fixedly mounted on the top surface of the processing table 1, a limit rod 412 is slidably provided inside the first L-shaped plate 411, a pressure plate 413 is fixedly mounted on the end of the limit rod 412, the top surface of the pressure plate 413 is rotatably connected to a screw 414, and the outer wall of the screw 414 is provided with a second L-shaped plate 415, the top surface of the processing table 1 A winding groove 416 is provided, and a rotating column 417 is rotatably connected to the inner side of the winding groove 416. A roller 418 is fixedly installed on the end of the rotating column 417. A screw 419 is sleeved on the outer wall of the rotating roller 418, and a splint 420 is sleeved on the outer wall of the screw 419. A ratchet 421 is fixedly sleeved on the outer wall of the rotating column 417. A clamping plate 422 is hinged on the inner wall of the winding groove 416. A first spring 423 is fixedly installed on the top surface of the clamping plate 422, and a fixing plate 424 is fixedly installed on the end of the first spring 423 away from the clamping plate 422.

[0028] When the film body 3 needs to be hot-pressed and welded, one end of the film body 3 is placed at the bottom of the pressure plate 413 and the screw 414 is rotated. Since the limiting rod 412 is slidably arranged inside the first L-shaped plate 411, the rotating screw 414 pushes the pressure plate 413 downward to clamp the end of the film body 3, and the other end of the film body 3 is placed between the clamping plate 420 and the roller 418. The screw 419 is rotated to make the clamping plate 420 press and clamp the film body 3. At this time, the roller 418 is rotated, which drives the rotating column 417 fixed at the end to rotate accordingly, and the ratchet 421 fixed on the outer wall of the rotating column 417 rotates accordingly. The outer wall of the ratchet 421 contacts and squeezes the clamping plate 422, and the clamping plate 422 is squeezed to mate with the winding groove 4 16 hinge is the center of rotation and compresses the first spring 423. When the card plate 422 is not squeezed by the ratchet 421, the card plate 422 is pushed back to its original position under the elastic action of the first spring 423, and the rotating roller 418 rolls up the membrane 3 and tightens it. When the membrane 3 is in a taut state, the roller 418 is no longer rotated, and the outer wall block of the ratchet 421 contacts and engages with the end of the card plate 422 to prevent the roller 418 from rotating. Under the winding cooperation of the pressure plate 413 and the roller 418, the membrane 3 is tightened so that wrinkles will not be generated during hot pressing, thereby improving the hot pressing welding effect (the processing table 1 and the hot pressing welding mechanism 2 are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0029] Furthermore, the end of the card plate 422 is slidably arranged with the outer wall of the ratchet 421, and the end of the card plate 422 is arranged at an inclined surface. Under its restriction, the card plate 422 contacts and engages with the outer wall block of the ratchet 421 to prevent the roller 418 from rotating.

[0030] Furthermore, the side of the pressure plate 413 away from the limit rod 412 is made of rubber material, and the second L-shaped plate 415 is fixedly installed on the top surface of the processing table 1. The rubber pressure plate 413 can avoid damaging the membrane 3 by pressing. Under the restriction of the second L-shaped plate 415, the screw 414 can be rotated to push the pressure plate 413 connected to its end.

[0031] Example 2: Based on Example 1, a preferred embodiment of a waterproof breathable membrane hot pressing welding device provided by the present invention is as follows: Figures 1 to 6 As shown: the cleaning assembly 43 includes a fixed rod 431 fixedly mounted on the top surface of the processing table 1, a second spring 432 is sleeved on the outer wall of the fixed rod 431, a first ring 433 is slidably mounted on the outer wall of the fixed rod 431, a sliding rod 434 is fixedly mounted on the outer wall of the first ring 433, a second ring 435 is slidably mounted on the outer wall of the sliding rod 434, and a cleaning strip 436 is fixedly mounted on the outer wall of the second ring 435.

[0032] In this embodiment, when the membrane body 3 needs to be hot-pressed and welded, it is tightly clamped and its surface needs to be cleaned to prevent debris from being hot-pressed into the interior of the membrane body 3. Under the elastic action of the second spring 432, the first ring 433 is pushed downward, so that the first ring 433 drives the slide bar 434 to move downward accordingly, and the second ring 435 slidingly arranged on the outer wall of the slide bar 434 drives the cleaning bar 436 to move downward accordingly, so that the cleaning bar 436 contacts and presses the surface of the membrane body 3. At this time, the cleaning bar 436 is pulled to make the second ring 435 fixed on the top surface of the cleaning bar 436 slide on the outer wall of the slide bar 434 to clean the dust attached to the outer wall of the membrane body 3. This structure can ensure that there is no impurity on the surface of the membrane body 3 before hot-pressing welding, so as to improve the hot-pressing welding effect.

[0033] Furthermore, the side of the cleaning strip 436 away from the second ring 435 is made of a flexible adsorption material, and the outer wall of the cleaning strip 436 is arranged in an inclined surface. Under the restriction of the inclined surface, the cleaning strip 436 sliding with the membrane 3 can avoid damaging the membrane 3.

[0034] In addition, one end of the second spring 432 is fixedly installed on the top surface of the first ring 433, and the end of the second spring 432 away from the first ring 433 is fixedly installed on the end of the fixing rod 431 away from the processing table 1. Under the elastic action of the second spring 432, the cleaning strip 436 and the membrane body 3 are fitted and slid, and the membrane body 3 can be easily passed from under the cleaning strip 436.
