Description

Technical Field

[0001] This utility model relates to the field of tarpaulin testing technology, and in particular to a PE tarpaulin tensile testing device. Background Technology

[0002] PE tarpaulin is a type of tarpaulin made primarily of polyethylene. Polyethylene itself has excellent waterproof properties, effectively preventing rainwater and snowmelt from penetrating and keeping the items covered by the tarpaulin dry. PE tarpaulins are lightweight, making them easy to handle, unfold, and store. They are also soft, easy to fold and roll, facilitating storage and transportation.

[0003] A search of existing technologies, referring to publication number CN219830622U, patent title: "A Tensile Strength Testing Device for Plastic Tarpaulins," points out that in existing technologies, the plastic tarpaulin needs to be manually clamped onto the tensile strength testing device using screws during tensile strength testing, which greatly increases the preparation time for the test, and the plastic tarpaulin is also prone to damage during the clamping process. To improve upon this, a tensile testing device for PE tarpaulins is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PE tarpaulin tensile testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A PE tarpaulin tensile testing device includes a base, on which a double-headed screw is mounted via a rotating groove and a moving motor. A winding roller is threaded onto the double-headed screw, and an adjusting screw is mounted on the winding roller via a support frame. A drive shaft is mounted on the winding roller via a support plate, and the adjusting screw is connected to the drive shaft via a rotating mechanism. A fixing frame is threaded onto the adjusting screw. A lifting frame is provided above the base, and a drive shaft is mounted on the lifting frame via a rotating motor. The drive shaft has a channel that mates with the drive shaft.

[0006] Preferably, the rotating mechanism includes a drive gear mounted on the drive shaft, and the adjusting screw is provided with a transmission gear that meshes with the drive gear.

[0007] Preferably, a lower limit rod is provided in the rotating groove, and the lower limit rod is parallel to the double-headed screw and slides through the winding roller.

[0008] Preferably, the support frame is provided with an upper limit rod, which is parallel to the adjusting screw and slides through the fixing frame.

[0009] Preferably, the drive shaft is in the shape of a hexagonal prism, and the vertical cross-section of the channel is designed as a regular hexagon.

[0010] Preferably, both the winding roller and the fixing frame are provided with protective pads, which are made of rubber and have anti-slip textures on their surface.

[0011] The beneficial effects of this utility model are: 1. Abandoning the traditional screw fixing method, a unique fixing assembly is formed by a winding roller, an adjusting screw, and a corresponding rotating mechanism. This improves the stability and reliability of the device.

[0012] 2. Compared with traditional screw fixing, there is no need to manually tighten each bolt one by one, which greatly saves operation time and labor costs, significantly improves the efficiency of testing work, and is especially suitable for batch testing scenarios.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4A PE tarpaulin tensile testing device includes a base 1. A double-headed screw 3 is mounted on the base 1 via a rotating groove 2 and a moving motor 4. A winding roller 5 is threaded onto the double-headed screw 3. An adjusting screw 9 is mounted on the winding roller 5 via a support frame 8. A drive shaft 15 is mounted on the winding roller 5 via a support plate 14. The adjusting screw 9 is connected to the drive shaft 15 via a rotating mechanism. A fixing frame 10 is threaded onto the adjusting screw 9. A lifting frame 6 is located above the base 1. Bolts 7 are mounted on the lifting frame 6, allowing it to be hoisted and installed on the workshop ceiling. A drive shaft 12 is mounted on the lifting frame 6 via a rotating motor 11. A channel 18 mates with the drive shaft 12 on the drive shaft 15.

[0017] It should be noted that the PE tarpaulin tensile testing device includes fixing components and testing components. This solution only addresses the issues and improvements to the fixing components. For the testing components, please refer to the existing publicly available technologies.

[0018] The rotating mechanism includes a drive gear 16 mounted on the drive shaft 15, and a transmission gear 17 meshing with the drive gear 16 on the adjusting screw 9. As shown in the figure, both the drive gear 16 and the transmission gear 17 are bevel gears, which mesh perpendicularly with each other to achieve power transmission. Since bevel gears are a mature existing technology, the teeth on the gears are not shown in the attached figures of this scheme, in order to better observe the structure of other components in the figures.

[0019] A lower limit rod 13 is provided in the rotating groove 2. The lower limit rod 13 is parallel to the double-headed screw 3 and slides through the winding roller 5. An upper limit rod is provided on the support frame 8. The upper limit rod is parallel to the adjusting screw 9 and slides through the fixing frame 10. The lower limit rod 13 and the upper limit rod respectively limit the winding roller 5 and the fixing frame 10, preventing them from rotating together with the double-headed screw 3 and the adjusting screw 9.

[0020] The drive shaft 12 is in the shape of a hexagonal prism, and the vertical cross-section of the channel 18 is a regular hexagon. This design allows the drive shaft 12 to rotate synchronously with the drive shaft 15 when the drive shaft 12 rotates with the rotating motor 11. Furthermore, the synchronous rotation can still be achieved after the drive shaft 15 moves horizontally with the support plate 14 and the winding roller 5.

[0021] Both the winding roller 5 and the fixing frame 10 are equipped with protective pads. The protective pads are made of rubber and have anti-slip textures on the surface. The aforementioned rubber protective pads with anti-slip textures are not shown in the figure. Their main function is to protect the PE tarpaulin between the two from being fixed, squeezed, or damaged.

[0022] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods of each component adopt mature methods in the prior art, and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0023] When using this utility model, such as Figure 1 As shown, in the initial state, the two winding rollers 5 are close together, and the two ends of the PE tarpaulin are bent and wrapped around the winding rollers 5. Then, the rotating motor 11 is started to drive the transmission shaft 12 to rotate. The transmission shaft 12 can be matched with the drive gear 16 and the transmission gear 17 to drive the adjusting screw 9 to rotate. When the adjusting screw 9 rotates, the fixing frame 10 moves closer to the outer wall of the winding roller 5, and then the end of the PE tarpaulin is fixed on the winding roller 5. Then, the moving motor 4 is started to drive the double-headed screw 3 to rotate. At this time, the two winding rollers 5 move away from each other, realizing the stretching operation of the PE tarpaulin. During the stretching process, it can be tested with mature testing components in the existing technology.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
