Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material production devices, in particular to a splicing machine for waterproof coiled material production. Background Art

[0002] Waterproof membrane refers to a waterproof material product made by impregnating asphalt or polymer waterproof materials on the carcass. It is a waterproof material provided in the form of a membrane. Waterproof membrane is mainly used for building walls, roofs, as well as tunnels, roads, landfills, etc., to protect against external rainwater and groundwater leakage. It plays a vital role in construction projects. During the production and use of waterproof membranes, the waterproof membranes need to be overlapped so that the two waterproof membranes can be tightly connected together. However, the overlapping device used for overlapping waterproof membranes generally uses open flames for direct baking and hot melting. Basically, it can only be hot-melted on the top surface of the waterproof membrane, and hot melting often leads to uneven heating, affecting the quality of the waterproof membrane overlap. In view of this, we propose an aluminum plate heating device for a carcass overlapping machine for waterproof membrane production.

[0003] A patent with announcement number CN215661910U is disclosed in the prior art. The solution includes two support rods, one side of the two support rods is clamped with a hanging plate, the upper surface of the hanging plate is provided with a waterproof membrane, the inner sides of the upper ends of the two support rods are slidably connected with a lifting block, a threaded rod is rotatably sleeved between the two lifting blocks, a guide rod located above the threaded rod is fixedly connected between the two lifting blocks, the lower ends of the two lifting blocks are fixedly connected to a first pneumatic cylinder fixedly connected to the inner side of the support rod, and one side of one of the lifting blocks is fixedly connected to a driving mechanism. The utility model has a simple structure, which can make the asphalt waterproof membrane more tightly connected at the overlap, prevent it from detaching during use, and make the pressing effect better, simple to operate, and easy to use.

[0004] The existing devices including the above patents have gradually exposed the shortcomings of the existing technology as they are used, mainly in the following aspects:

[0005] First, during the overlapping process, the existing waterproof membrane needs to be heated to perform hot-melt bonding on the overlapping positions of the membrane. This means that after the overlapping bonding is completed, the membrane needs to be kept still for a long time to wait for cooling, which affects the production and use of subsequent membranes that need to be overlapped.

[0006] Second, during the overlapping process, the existing waterproof membrane is limited by the limitations of the overlapping structure, and it is impossible to quickly overlap and bond the waterproof membrane, which affects the overlapping efficiency.

[0007] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0008] In response to the defects in the existing technology, the utility model provides a splicing machine for the production of waterproof membranes, which is used to solve the problem that in the traditional technology, the overlapping positions of the waterproof membranes need to be hot-melt bonded by heating during the splicing process. This means that after the splicing is completed, the machine needs to be stationary for a long time to wait for the membrane to cool down, which affects the production and use of subsequent membranes that need to be spliced.

[0009] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] A splicing machine for producing waterproof membranes comprises a workbench, wherein a bottom refrigeration cavity shell is fixedly connected to the workbench, a bottom mounting plate is fixedly connected to the upper end of the bottom refrigeration cavity shell, a plurality of bottom heating plates are fixedly connected in parallel to the bottom mounting plate, and a plurality of bottom cooling cylinders connected to the bottom refrigeration cavity shell are fixedly connected in parallel in the area between adjacent bottom heating plates; a top refrigeration cavity shell is vertically raised and lowered above the workbench, a top mounting plate is fixedly connected to the lower end of the top refrigeration cavity shell, a plurality of top heating plates are fixedly connected in parallel to the top mounting plate, and a plurality of top cooling cylinders connected to the top refrigeration cavity shell are fixedly connected in parallel in the area between adjacent top heating plates.

[0015] As an optimized solution, a bottom cooling medium pipe is arranged in an S-shaped circuit inside the bottom refrigeration cavity shell, and both ends of the bottom cooling medium pipe extend to the outside of the bottom refrigeration cavity shell respectively, and are fixedly connected with a bottom cooling medium inlet and a bottom cooling medium outlet.

[0016] As an optimized solution, a plurality of bottom heat dissipation fins are fixedly connected in parallel to the outer wall of the bottom cooling medium tube along its extension direction.

[0017] As an optimized solution, a top cooling medium pipe is arranged in an S-shaped circuit inside the top refrigeration cavity shell, and both ends of the top cooling medium pipe extend to the outside of the top refrigeration cavity shell respectively, and are correspondingly fixed with a top cooling medium inlet and a top cooling medium outlet.

[0021] As an optimized solution, a plurality of through holes for avoiding the top cooling tube are opened on the top mounting plate. The top cooling tube passes through the through holes and is fixed to the top refrigeration cavity shell.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By setting up several bottom heating plates to support the coils to be overlapped, and then the telescopic cylinder drives the top heating plate to move downward, the overlapping coils can be quickly hot-melted and bonded under the dual action of the bottom heating plate and the top heating plate, thereby improving the hot-melt efficiency. The top refrigeration chamber shell is hinged on the telescopic cylinder, which allows the top refrigeration chamber shell to swing slightly during the hot-melt bonding process, reducing the impact caused by the uneven height of the overlap position and improving the overlap efficiency.

[0024] After the overlap is completed, the heating plate on the top of the telescopic cylinder rises a certain distance and then separates from the coil. The bottom air inlet tube and the top air inlet tube are respectively connected to the air source to supply air. The air is blown to the upper and lower surfaces of the coil through the bottom cooling tube and the top cooling tube respectively to cool the coil. The staggered arrangement of the bottom cooling tube and the top cooling tube can improve the uniformity of cooling and the heat dissipation efficiency.
