Description

Technical Field

[0001] This utility model relates to the field of membrane processing equipment technology, specifically a polyurethane membrane roll forming and stretching equipment. Background Technology

[0002] Polyurethane film is an environmentally friendly material with excellent elasticity and high lightness. Despite its extremely thin thickness, it exhibits unparalleled waterproof properties compared to other materials. High-tech methods are used to introduce hydrophilic agents into the material, giving the film not only high waterproof performance but also excellent moisture permeability. A calender consists of two or more rollers arranged according to the heating method. It can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating. Hot pressing is a machine that presses and stretches materials into sheets of a certain thickness and surface shape at a specific temperature. During hot pressing, a layer of adhesive needs to be applied between the two layers of film to ensure adhesion. During hot pressing, the adhesive between the two layers flows outward through the gaps on both sides and adheres to the rollers. Excessive adhesive on the rollers effectively reduces the distance between the two rollers, causing excessive compression of the film during the hot pressing process. Utility Model Content

Detailed Implementation

[0014] 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.

[0015] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a polyurethane film roll forming and stretching device.

[0016] Example 1:

[0017] Please see Figures 1-7 A polyurethane film roll forming and stretching device includes a processing table 1, a main roller 2 and an auxiliary roller 3 disposed on the processing table 1. The processing table 1 includes a base 101 and support plates 102 located on both sides of the top of the base 101. The two ends of the main roller 2 are rotatably connected to the support plates 102 through bearings. The auxiliary roller 3 is movably installed between the two support plates 102 and located on top of the main roller 2. A driving component 4 is provided on the auxiliary roller 3 to drive the auxiliary roller 3 to move up and down between the two support plates 102. A cleaning device 5 is provided on the top of the auxiliary roller 3. The driving component 4 drives the cleaning device 5 to move synchronously with the auxiliary roller 3. The cleaning device 5 includes a scraper 51, a drying unit 52, and a collection unit 53. The scraper 51 scrapes the surfaces of the auxiliary roller 3 and the main roller 2. The drying unit 52 dries the impurities on the scraper 51. The collection unit 53 collects the dried impurities on the scraper 51.

[0018] Specifically, a polyurethane film is placed between the main roller 2 and the auxiliary roller 3. The position between the auxiliary roller 3 and the main roller 2 is then adjusted by the drive component 4. The main roller 2 is then rotated, and the polyurethane film is pressed and stretched by the main roller 2 and the auxiliary roller 3. During the pressing and stretching process, the adhesive in the middle of the polyurethane film will seep out through the gaps on both sides of the polyurethane film and adhere to the main roller 2 and the auxiliary roller 3. At this time, the adhesive on the main roller 2 and the auxiliary roller 3 is scraped off by the scraper component 51. When the scraper component 51 scrapes off the adhesive on the main roller 2, the adhesive will flow onto the base 101 and be collected by the existing collection device on the base 101. When the scraper component 51 scrapes off the adhesive on the auxiliary roller 3, the adhesive on the scraper component 51 is dried by the drying group 52, and the dried adhesive on the scraper component 51 is collected by the collection group 53. During the pressing and stretching of the polyurethane film, the glue overflowing to both sides of the main roller 2 and the auxiliary roller 3 is scraped off by the scraper 51 in the cleaning device 5 to prevent the overflowing glue from adhering to the main roller 2 and the auxiliary roller 3. Otherwise, excessive glue will adhere to the main roller 2 and the auxiliary roller 3, which is equivalent to reducing the distance between the two pressing rollers and causing excessive compression of the film during the hot pressing process.

[0019] Example 2:

[0020] The difference from the above embodiments is that, see below Figures 1-7 A disc 103 and a support 104 are fixedly connected to one side of the support plate 102. Gears 105 are rotatably connected to the disc 103 and the support 104 via bearings. A connecting shaft 106 is fixedly connected to one of the gears 105. The gear 105 is fixedly connected to one end of the main roller 2 via the connecting shaft 106. A first motor 107 is fixedly connected to the support 104. The output end of the first motor 107 is fixedly connected to the other gear 105. A toothed belt 108 is fitted on both gears 105 and meshes with them. Specifically, the first motor 107 operates, driving one of the gears 105 to rotate. Through the meshing connection between the two gears 105 and the toothed belt 108, it drives the other gear 105 to rotate, thereby driving the connecting shaft 106 and the main roller 2, which are fixedly connected to the gears 105, to rotate.

[0021] Example 3:

[0022] The difference from the above embodiments is that, see below Figures 1-7 The driving component 4 includes a bearing seat 41, a guide rail groove 42 is provided on the support plate 102, the bearing seat 41 is slidably disposed on the guide rail groove 42, the two ends of the auxiliary roller 3 are rotatably connected to the bearing seat 41 through bearings, and a first cylinder 43 is fixedly connected to the top of the support plate 102, and the output end of the first cylinder 43 is fixedly connected to the bearing seat 41. Specifically, the first cylinder 43 operates, driving the bearing seat 41 to move up and down on the guide rail groove 42, thereby adjusting the position between the main roller 2 and the auxiliary roller 3.

[0023] Example 4:

[0024] The difference from the above embodiments is that, see below Figures 1-7The scraping component 51 includes a scraper 511, a sliding seat 512 is fixedly connected to the bearing seat 41, and a fixed plate 513 is fixedly connected to both ends of one side of the sliding seat 512. A transmission roller 514 is rotatably connected between the two fixed plates 513 through a bearing. A transmission belt 515 is sleeved on the outer periphery of the two transmission rollers 514. Multiple scrapers 511 are fixedly installed on the transmission belt 515. The bottom end of the scraper 511 is in contact with the outer periphery of the auxiliary rotating roller 3. A second motor 516 is fixedly connected to one side of the fixed plate 513. The output end of the second motor 516 is fixedly connected to one of the transmission rollers 514. The scraping component 51 also includes a baffle 517, which is fixedly installed on the base 101. The baffle 517 is located between the base 101 and the main roller 2 and its top is in contact with the surface of the main roller 2. Specifically, when the main roller 2 rotates, the adhesive on the surface of the main roller 2 is scraped off by the baffle 517 because the top of the baffle 517 is attached to the surface of the main roller 2. The adhesive then flows downward on the surface of the baffle 517 by gravity. When the auxiliary roller 3 rotates, the second motor 516 drives one of the transmission rollers 514 to rotate. The transmission belt 515 rotates through the sleeve between the two transmission rollers 514, thereby scraping off the adhesive on the auxiliary roller 3 by the scraper 511.

[0025] Example 5:

[0026] The difference from the above embodiments is that, see below Figures 1-7 The drying unit 52 includes a drying box 521, a load-bearing plate 522 is fixedly connected between two sliding seats 512, the drying box 521 is fixedly installed on the load-bearing plate 522, and the transmission belt 515 passes through the drying box 521. Specifically, after the scraper 511 scrapes off the glue on the auxiliary roller 3, the scraper 511 rotates upward with the transmission belt 515, so that the glue adheres to one side of the scraper 511 and the connection between the scraper 511 and the transmission belt 515. After the scraper 511 moves into the drying box 521 with the transmission belt 515, the glue on the scraper 511 is dried by the drying box 521, which facilitates the processing and collection of the glue.

[0027] Example 6:

[0028] The difference from the above embodiments is that, see below Figures 1-7The collection group 53 includes a collection chamber 531, which is fixedly installed on the load-bearing plate 522. A collection component 532 is provided on the collection chamber 531. Two horizontal plates 533 are fixedly connected to the collection chamber 531. The collection component 532 is located between the two horizontal plates 533 and at the top of the transmission belt 515. Telescopic plates 534 are fixedly connected to both sides of the collection component 532. One end of the telescopic plate 534 is fixedly connected to the horizontal plate 533. A second cylinder 535 is fixedly connected to one side of the horizontal plate 533. The output end of the second cylinder 535 is fixedly connected to the collection component 532. The collecting component 532 includes a fixed platform 5321. Rotating rollers 5322 are rotatably connected to both sides of the fixed platform 5321 via bearings. A rotating belt 5323 is sleeved on the outer periphery of the rotating rollers 5322. Multiple cleaning plates 5324 are fixedly connected to the outer periphery of the rotating belt 5323. A third motor 5325 is fixedly connected to the fixed platform 5321. The output end of the third motor 5325 is fixedly connected to one end of one of the rotating rollers 5322. One end of the telescopic plate 534 is fixedly installed on the fixed platform 5321. The output end of the second cylinder 535 is fixedly connected to the fixed platform 5321. Specifically, the third motor 5325 operates, driving one of the rotating rollers 5322 to rotate. Through the connection between the rotating belt 5323 and the two rotating rollers 5322, the rotating belt 5323 rotates, thereby causing the cleaning plate 5324 to rotate along with the rotating belt 5323. This allows the cleaning plate 5324 to scrape off the dried glue from one side of the scraper 511 and the connection between the scraper 511 and the transmission belt 515. The pushing force generated by the movement of the cleaning plate 5324 collects the scraped dried glue into the collection bin 531. Since the transmission belt 515 is constantly moving, the second... The output end of cylinder 535 is fixedly connected to fixed platform 5321, and the fixed platform 5321 is fixedly connected to horizontal plate 533 on both sides through telescopic plate 534. This arrangement allows the scraper 511 to move synchronously with the collection component 532 as it follows the transmission belt 515. As a result, the cleaning plate 5324 moves synchronously with the scraper 511 during the scraping process. When one set of cleaning plates 5324 disengages from the scraper 511, the second cylinder 535 drives the collection component 532 to reset, and the other set of cleaning plates 5324 cleans the dried glue on the subsequent scraper 511.
