Description

Technical Field

[0001] This utility model relates to the field of waterproof fabric production technology, and in particular to a base splicing device for the production of non-reflective PVC waterproof fabric. Background Technology

[0002] Waterproof building materials are used to prevent rainwater, groundwater, liquids, and moisture from penetrating buildings, and are mainly used in roofs, walls, and other areas. In the production of waterproof fabric, because the length of a single roll of base material is limited, continuous production requires base material splicing, a process that directly affects the overall performance and quality stability of the waterproof fabric.

[0003] Currently, the main methods for joining tire bases involve hot pressing or adhesive bonding, using a heating plate to fuse the materials together. This method is characterized by its ease of operation and high efficiency. However, due to the lack of a flattening function, the tire base is prone to surface wrinkles during the heating process. This not only results in unevenness at the joint but also affects the overall flatness and appearance quality of the waterproof fabric. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing technology lacks a flattening function, and the base material is prone to surface wrinkles due to heat during the heating process. This not only causes unevenness at the seams, but also affects the overall flatness and appearance quality of the waterproof fabric. Therefore, this invention proposes a base material splicing device for the production of non-reflective PVC waterproof fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A base splicing device for producing non-reflective PVC waterproof fabric includes a workbench, a T-shaped plate and a lifting plate respectively arranged above the workbench, a movable seat sliding vertically above the lifting plate, a pair of sliding seats sliding horizontally on the lifting plate, a pair of vertical plates fixedly connected to the bottom surface of the sliding seats, and a rotating roller rotatably connected to the vertical plates.

[0007] Also includes:

[0008] A traction assembly that causes the movable seat to drive the two sliding seats to slide horizontally in sync.

[0009] A driving component that drives the movable base to slide vertically;

[0010] The drive assembly includes a support plate that is vertically slidably connected to the T-shaped plate, and the support plate and the lifting plate are fixedly connected to the same cylinder.

[0011] Preferably, a transmission rod is rotatably connected to the bottom of the support plate, a screw is fixedly connected to the bottom end of the transmission rod, the screw is threadedly connected to the movable seat, and a second motor for driving the transmission rod to rotate is fixedly connected to the top of the support plate.

[0012] Preferably, the transmission rod is embedded in the T-shaped plate, and the transmission rod and the T-shaped plate are movably connected.

[0013] Preferably, the traction assembly includes a vertical plate fixedly connected to the opposite sidewalls of the sliding seat and the movable seat, and the vertical plates are arranged in pairs. A short shaft is fixedly connected to the vertical plate, and a traction plate is rotatably sleeved on the short shaft.

[0014] Preferably, a support frame is fixedly connected to the top of the workbench, and a pair of plates are fixedly connected to the support frame. The same lead screw is rotatably connected to the opposite sidewalls of the two plates. A motor for driving the lead screw to rotate is fixed on the plates. A threaded sleeve is threadedly connected to the lead screw, and the bottom of the threaded sleeve is fixedly connected to the T-shaped plate.

[0015] Preferably, the top of the workbench has a groove, and multiple electric heating plates are fixedly installed in the groove.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] This invention, through the arrangement of traction and drive components, allows the transmission rod to drive the screw to rotate when the second motor starts, driving the moving seat to press down vertically. At the same time, the traction plate links the sliding seats on both sides to move synchronously in opposite directions, so that the rotating roller applies uniform pressure to the base, effectively eliminating surface wrinkles and ensuring that the joint of the waterproof cloth after splicing is flat, tight, and free of bubbles, thereby improving the bonding strength and appearance quality of the product.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-3 A base-joining device for producing non-reflective PVC waterproof fabric includes a workbench 1. A T-shaped plate 2 and a lifting plate 6 are respectively arranged above the workbench 1. A movable seat 5 slides vertically above the lifting plate 6. A pair of sliding seats 9 are horizontally slidably mounted on the lifting plate 6. A pair of vertical plates 7 are fixedly connected to the bottom surface of the sliding seats 9. Rotary rollers 8 are rotatably connected to the vertical plates 7. The synchronous movement of the two rollers 8 flattens the wrinkles on the surface of the base fabric. A support plate 31 and the lifting plate 6 are fixedly connected to the same cylinder 61. The lifting plate 6 is raised and lowered as a whole by the cylinder 61, flexibly adjusting the pressing height to ensure that the contact pressure between the rollers 8 and the base fabric is moderate.

[0030] Also includes:

[0031] The traction component enables the movable seat 5 to drive the two sliding seats 9 to slide horizontally in sync.

[0032] The driving component drives the moving seat 5 to slide vertically.

[0033] The drive assembly includes a support plate 31 vertically slidably connected to the T-shaped plate 2. A transmission rod 3 is rotatably connected to the bottom of the support plate 31, and a screw 4 is fixedly connected to the bottom end of the transmission rod 3. The screw 4 and the movable seat 5 are threadedly connected. A second motor 32 for driving the transmission rod 3 to rotate is fixedly connected to the top of the support plate 31. The second motor 32 drives the transmission rod 3 to rotate, which in turn drives the screw 4 to precisely raise and lower the movable seat 5, ensuring the smooth horizontal sliding of the sliding seat 9 during the pressing process.

[0034] The transmission rod 3 is embedded in the T-shaped plate 2, and the transmission rod 3 and the T-shaped plate 2 are movably connected. The transmission rod 3 can slide vertically on the T-shaped plate 2, and can also rotate on the T-shaped plate 2.

[0035] The traction assembly includes a vertical plate 62 fixedly connected to the opposite side walls of the sliding seat 9 and the movable seat 5, and the vertical plates 62 are arranged in pairs. A short shaft 63 is fixedly connected to the vertical plate 62, and a traction plate 64 is rotatably sleeved on the short shaft 63.

[0036] A support frame 10 is fixedly connected to the top of the workbench 1. A pair of plates 21 are fixedly connected to the support frame 10. The same lead screw 22 is rotatably connected to the opposite side walls of the two plates 21. A motor 24 for driving the lead screw 22 is fixed on the plate 21. A threaded sleeve 23 is threaded onto the lead screw 22. The threaded sleeve 23 and the support frame 10 are horizontally slidably connected to ensure that the threaded sleeve 23 can move stably horizontally along the axis of the lead screw 22. The bottom of the threaded sleeve 23 is fixedly connected to a T-shaped plate 2. The lead screw 22 is driven by the motor 24, which causes the threaded sleeve 23 to drive the T-shaped plate 2 to slide smoothly, thus achieving the flattening requirement of wrinkles in different parts of the tire base.

[0037] The top of the workbench 1 has a groove 11, and multiple electric heating plates 12 are fixedly installed in the groove 11. The electric heating plates 12 can achieve temperature control to ensure that the PVC coating at the tire base joint melts evenly; the groove 11 can effectively concentrate heat and reduce energy loss.

[0038] The functional principle of this utility model can be explained through the following operation methods:

[0039] First, start the motor 24 to drive the lead screw 22 to rotate, which in turn moves the screw sleeve 23 and the T-shaped plate 2 horizontally to the position above the fold of the tire base to be continued.

[0040] The lifting plate 6 adjusts its height via cylinder 61, causing the rotating roller 8 to lightly press against the tire base surface.

[0041] After the motor 2 32 starts, the transmission rod 3 drives the screw 4 to rotate, causing the moving seat 5 to descend vertically. Through the traction plate 64, the two sliding seats 9 slide synchronously relative to each other or in opposite directions, so that the rotating roller 8 flattens the wrinkles on the surface of the tire base.

[0042] After flattening is completed, cylinder 61 lifts the lifting plate 6, the rotating roller 8 detaches from the tire base surface, motor 2 32 reverses to lift the moving seat 5 back to its original position, and the sliding seat 9 returns to its original position under the action of traction plate 64.

[0043] Throughout the process, the rotation of the roller 8 ensures the flattening of the wrinkles on the base surface, and the precise temperature control of the electric heating plate 12 enables the PVC coating to melt and bond, ultimately forming a smooth and bubble-free waterproof fabric joint.

[0044] 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.
