Description

Technical Field

[0001] The utility model relates to the technical field of film stretching, in particular to a heat preservation device for a TDO film stretching machine. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. During film production, a film stretching machine is usually used to stretch the film raw material through the TDO biaxial stretching process to obtain a preformed film, which is then stored in a heat-insulated manner.

[0003] Currently available thermal insulation storage equipment usually uses an insulation cover for insulation protection. However, since the newly produced film will have a certain temperature, when the film temperature is high, heat will be dissipated inside the insulation cover. The rising heat will come into contact with the top of the insulation equipment, causing water droplets to condense and drip, resulting in the film being unable to dry and inconvenient for subsequent winding. Summary of the Invention

[0004] In order to solve the existing technical problems, the utility model provides a TDO film stretching machine heat preservation device.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A thermal insulation device for a TDO film stretching machine includes a base, a thermal insulation cover fixed to the top of the base, a guide cavity provided inside both side walls of the thermal insulation cover, the tops of the two guide cavities extending through the top of the thermal insulation cover, the bottoms of the two guide cavities extending through the outer surface of one side of the thermal insulation cover, an arc-shaped opening provided on the top of the thermal insulation cover near both side edges, the two arc-shaped openings correspondingly extending through the interior of the guide cavity, and the inner arc surfaces of the two arc-shaped openings extending to one side of the guide cavity.

[0007] Optionally, a protective cover is provided on the outer surface of the heat-insulating cover near the top edge, and a gap is left between the inner wall of the protective cover and the outer surface of the heat-insulating cover.

[0008] Optionally, torque shafts are provided on both inner walls of the protective cover, and a sealing top plate is fixed to one side of the two torque shafts.

[0009] Optionally, a sealing groove is formed at the bottom of each of the two sealing top plates, one side of each of the two sealing grooves passes through one side of the sealing top plate, and the two sealing grooves are connected to each other.

[0010] Optionally, the top of the heat-insulating cover is open and extends between the inner walls of the two sealing grooves.

[0011] Optionally, guide plates are fixed to the outer surfaces of both sides of the heat-insulating cover, and the two guide plates are correspondingly located at the bottom opening of the guide cavity.

[0012] Optionally, a safety door is provided on the front side of the thermal insulation cover, and mounting grooves are provided at the four corners of the top of the base, and electric telescopic rods are fixed inside the four mounting grooves. The bottom of the protective cover is fixed with connecting blocks at the four corners, and the tops of multiple electric telescopic rods are fixed to the bottoms of the connecting blocks.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] 1. In the present invention, a diversion cavity is provided inside both side walls of the heat-insulating cover, and an arc-shaped opening is provided at the top of the heat-insulating cover near both side edges. The two arc-shaped openings are correspondingly penetrated into the interior of the diversion cavity, so that the inner arc surface of the arc-shaped opening extends to one side of the diversion cavity. Therefore, when water flows into the arc-shaped opening, the water flows from the arc surface of the inner bottom surface of the arc-shaped opening to the diversion cavity for discharge, thereby preventing water from accumulating inside the arc-shaped opening.

[0015] In the utility model, the top of the heat preservation cover is set to be open and extended to the inside of the sealing groove at the bottom of the sealing top plate. When water droplets are generated on the top surface of the sealing groove, the electric telescopic rod can be retracted to drive the protective cover to descend. During the descent of the protective cover, the inner top surface of the sealing groove will fit with one side of the arc-shaped opening to scrape off the water droplets on the inner top surface of the sealing groove, thereby preventing the generated water droplets from dripping onto the film inside the heat preservation cover.

[0026] The effect achieved by the entire embodiment 1 is that a diversion cavity 9 is opened inside the two side walls of the heat-insulating cover 2, and an arc-shaped opening 12 is opened at the top of the heat-insulating cover 2 near the two side edges, and the two arc-shaped openings 12 are correspondingly penetrated into the interior of the diversion cavity 9, so that the internal arc surface of the arc-shaped opening 12 extends to one side of the diversion cavity 9, so that when water flows into the arc-shaped opening 12, the water flow is guided from the arc surface of the bottom surface of the arc-shaped opening 12 to the diversion cavity 9 for discharge, thereby preventing water from accumulating inside the arc-shaped opening 12.

[0027] Example 2, as Figure 1-4As shown, a protective cover 7 is provided on the outer surface of the heat preservation cover 2 near the top edge, and a gap is left between the inner wall of the protective cover 7 and the outer surface of the heat preservation cover 2.
