Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waterproof membrane production equipment, and in particular to a winding device for the production of EPDM waterproof membranes. Background Technology
[0002] EPDM rubber waterproof membrane is made by mixing EPDM rubber with appropriate amounts of butyl rubber, vulcanizing agent, accelerator, softener and reinforcing agent, and processing through processes such as intensive mixing, sheeting and filtration, and extrusion molding. It is a high-efficiency waterproof material.
[0003] After the waterproof membrane is produced, it needs to be rolled up for transportation and use. Regarding rolling devices, a search reveals, for example, a rolling device for waterproof membrane production provided by patent publication number CN219885221U. This device includes a main frame, a drive motor fixedly mounted on the side of the main frame, and a shaft rotatably connected to the main frame. Both the output end of the drive motor and the end of the shaft are fixedly equipped with pulleys, and a belt is connected to the two pulleys. A replacement component is also included, mounted on the main frame. This component includes a moving plate, a connecting plate, an auxiliary frame, a second shaft, a rotating shaft, a fixed rod, a power motor, and a power shaft. The top of the moving plate is fixedly connected to the connecting plate, and the side of the connecting plate is fixedly connected to the auxiliary frame. The second shaft is rotatably mounted on the auxiliary frame, and discs are fixedly mounted at the ends of both the first and second shafts. This device allows for quick replacement of the rotating shaft, improving rolling efficiency.
[0004] Based on the above search and in conjunction with existing technologies, it has been found that existing winding devices for waterproof membrane production, similar to those disclosed above, require the winding roller (i.e., the rotating shaft in the aforementioned documents) to be replaced before the winding operation can begin. However, when replacing the winding roller, the completed roll of membrane needs to be removed, and the new winding roller needs to be installed on the winding device. These two steps undoubtedly consume a certain amount of time, and the winding efficiency needs to be further improved. Therefore, a winding device for EPDM waterproof membrane production is proposed to improve the above-mentioned problems. Utility Model Content
[0005] The purpose of this application is to provide a winding device for the production of EPDM waterproof membrane, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this application provides the following technical solution: a winding device for the production of EPDM waterproof membrane, including a bracket, a rotating shaft horizontally rotatably mounted on the inner side of the top of the bracket, and a drive motor for driving the rotating shaft to rotate mounted on the side end of the bracket;
[0007] Multiple winding units are fixed at equal intervals around the circumference of the rotating shaft. Each winding unit includes two automatic roll changing components for fixing the winding roller. Both automatic roll changing components are symmetrically fixed to both ends of the axial direction of the rotating shaft via connecting rods.
[0008] The upper end of the bracket is equipped with a take-up drive assembly that causes the automatic roll changer to rotate with the take-up roller.
[0009] The lower end of the bracket is equipped with an auxiliary roll changing structure that allows the take-up roller to disengage from the automatic roll changing assembly.
[0010] As a further supplement to this solution, the automatic roll changing assembly includes a mounting ring, a turntable, a locking block, and two friction wheels.

The second drive motor is mounted on the top of the bracket, and the first friction wheel is coaxially fixed with the output end of the second drive motor, and the first friction wheel is in contact with any one of the second friction wheels.
[0013] As a further supplement to this solution, the auxiliary roll changing structure includes an arc-shaped support and a limiting inclined block. The arc-shaped support is fixed to the side end of the bracket, the limiting inclined block is fixed to the outer surface of the arc-shaped support, and a conical block that matches the limiting inclined block is fixed to the end of the locking block near the bracket.

[0018] In summary, the technical effects and advantages of this utility model are as follows:
[0019] 1. In this utility model, by setting up multiple winding units, while one winding unit performs winding operations, the other winding units are respectively located at the positions of separating the winding roller and installing the winding roller, so as to realize that the winding operation and the roll changing operation are carried out simultaneously, thereby improving the winding efficiency.

[0028] 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.
[0029] Example 1: Reference Figure 1-4 The shown winding device for producing EPDM waterproof membrane includes a bracket 1. A rotating shaft 3 is horizontally rotatably mounted on the inner top of the bracket 1. A drive motor 2 for driving the rotating shaft 3 is mounted on the side end of the bracket 1. Multiple winding units are equidistantly fixed around the rotating shaft 3. Specifically, this embodiment uses three winding units as an example. Figure 1 As shown, while one winding unit is performing the winding operation, the other two winding units are located at the positions of the separating winding roller and the mounting winding roller, respectively, so that the winding operation and the roll changing operation can be carried out simultaneously, thereby improving the winding efficiency.
[0030] The winding unit includes two automatic winding change assemblies 4 for fixing the winding roller. Both automatic winding change assemblies 4 are symmetrically fixed to both ends of the rotating shaft 3 via connecting rods. Specifically, the automatic winding change assembly 4 includes a mounting ring 41, a turntable 42, a locking block 43, and a second friction wheel 410. The mounting ring 41 is fixed to the connecting rod. The turntable 42 is coaxially rotatably mounted on the inner side of the mounting ring 41. The second friction wheel 410 is coaxially fixed to the side end of the mounting ring 41 near the bracket 1. The locking block 43 slides horizontally through the mounting ring 41 and the second friction wheel 410. A tension spring 44 is fixed between the end of the locking block 43 near the bracket 1 and the second friction wheel 410.
[0031] The upper end of the bracket 1 is equipped with a winding drive assembly 5, which causes the automatic roll changing assembly 4 to rotate with the winding roller. Specifically, the winding drive assembly 5 includes a second drive motor 51 and a first friction wheel 52. The second drive motor 51 is installed at the top of the bracket 1. The first friction wheel 52 is coaxially fixed with the output end of the second drive motor 51, and the first friction wheel 52 is in contact with any one of the second friction wheels 410. The second drive motor 51 drives the first friction wheel 52 to rotate. Since the first friction wheel 52 is in contact with the second friction wheel 410, the rotating first friction wheel 52 drives the second friction wheel 410 to rotate, thereby causing the automatic roll changing assembly 4 to rotate with the winding roller as a whole, realizing the winding of the EPDM waterproof membrane.
[0032] The lower end of the support 1 is equipped with an auxiliary roll changing structure 6 that allows the take-up roller to disengage from the automatic roll changing assembly 4. Specifically, the auxiliary roll changing structure 6 includes an arc-shaped support 61 and a limiting inclined block 62. The arc-shaped support 61 is fixed to the side end of the support 1, and the limiting inclined block 62 is fixed to the outer surface of the arc-shaped support 61. The end of the locking block 43 near the support 1 is fixed with a conical block 49 that matches the limiting inclined block 62. After the take-up roller is wound up, it carries the roll material and rotates downward with the automatic roll changing assembly 4 until the conical block 49 is pressed against the limiting inclined block 62. Under the pressing action of the limiting inclined block 62, the conical block 49 carries the locking block 43 and slides towards the side closer to the support 1. That is, the end of the locking block 43 away from the support 1 disengages from the take-up roller. After that, the roll material and the take-up roller fall off under their own gravity, realizing automatic unloading.
[0033] In addition, to facilitate the installation of the take-up roller, the automatic roll changing assembly 4 also includes a limiting block 46 and a pressure block 47. The limiting block 46 is slidably embedded in the side end of the locking block 43 located inside the turntable 42, and a compression spring 45 is fixed between the limiting block 46 and the locking block 43. A limiting groove 4101 adapted to the limiting block 46 is provided on the side of the turntable 42 near the friction wheel 410. The pressure block 47 is slidably installed inside the limiting groove 4101, and a compression spring 48 is fixed between the pressure block 47 and the outer surface of the turntable 42. The end of the locking block 43 away from the bracket 1 is fixed with a guide cone 411. When the automatic winding assembly 4 located at the auxiliary winding structure 6 continues to rotate 120 degrees to the position where the take-up roller is installed, the end of the locking block 43 away from the bracket 1 is located inside the turntable 42. At this time, the operator can align the take-up roller with the locking block 43 and manually press the pressure block 47 to make the limiting block 46 disengage from the limiting groove 4101. After that, the locking block 43 slides towards the side away from the bracket 1 under the action of the tension spring 44 and is inserted into the end slot of the take-up roller.
[0034] Of course, in order to ensure that the locking block 43 can be smoothly locked into the end slot of the take-up roller, the operator can manually rotate the take-up roller so that the slot at the upper end of the take-up roller is aligned with the locking block 43.
[0035] It should be further explained that, in order to ensure that the automatic roll changing assembly 4 can rotate stably with the take-up roller, the side end of the take-up roller is set to have the same shape as the vertical cross section of the clamping block 43, such as the prism shape shown in the figure.
[0036] In addition, the drive motors mentioned above can all be conventional electric motors, such as the TZ155X020 model, and can be electrically connected to a conventional controller to facilitate the operation of the drive motor by the staff.
[0037] The working principle of this utility model is as follows: When the drive motor 2 drives the rotating shaft 3 to rotate the automatic roll changing assembly 4 to the top position of one of the take-up rollers, the free end of the waterproof membrane is fixed on the take-up roller using conventional technical means; then the drive motor 51 drives the friction wheel 52 to rotate. Since the friction wheel 52 is in contact with the friction wheel 410, the rotating friction wheel 52 drives the friction wheel 410 to rotate, thereby making the automatic roll changing assembly 4 rotate with the take-up roller as a whole, realizing the winding of the EPDM waterproof membrane.
[0038] At the same time, after the winding is completed, the winding roller, along with the roll material, rotates downwards with the automatic roll changing assembly 4 until the conical block 49 is squeezed by the limiting inclined block 62. Under the squeezing action of the limiting inclined block 62, the conical block 49 slides towards the side closer to the bracket 1 with the locking block 43. That is, the end of the locking block 43 away from the bracket 1 disengages from the winding roller. After that, the roll material and the winding roller fall off under their own gravity, realizing automatic unloading.
[0039] At the same time, when the automatic roll changing assembly 4 located at the auxiliary roll changing structure 6 rotates 120 degrees to the position where the take-up roller is installed, the end of the locking block 43 away from the bracket 1 is still located inside the turntable 42. At this time, the operator can align the take-up roller with the locking block 43 and manually press the pressure block 47 to make the limiting block 46 disengage from the limiting groove 4101. After that, the locking block 43 slides towards the side away from the bracket 1 under the action of the tension spring 44 and is inserted into the end slot of the take-up roller.
[0040] Example 2: Reference Figure 5 An arc-shaped support seat 8 is fixed to the upper side of one side of the bracket 1 via a support plate 7. The arc-shaped support seat 8 is used to support the take-up roller. When installing the take-up roller, the take-up roller can be placed directly on the arc-shaped support seat 8. When one of the take-up units rotates to be flush with the take-up roller, the take-up roller can be installed. During the installation process, there is no need for the staff to manually lift the take-up roller, making the installation more labor-saving and convenient.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
