Description

Technical Field

[0001] The utility model relates to the technical field of insulating silicone rubber self-adhesive tape production, in particular to a drying device for producing insulating silicone rubber self-adhesive tape. Background Art

[0002] Insulating silicone rubber self-adhesive tape is a kind of tape with excellent insulating properties. It can be directly wrapped around the surface of objects that need insulation protection. Insulating silicone rubber self-adhesive tape is widely used in electronics, electrical appliances, communications, automobiles, aviation and other fields.

[0003] The specific production process of insulating silicone rubber self-adhesive tape is to prepare the raw materials first: select high-quality silicone rubber raw materials, add appropriate amounts of fillers, plasticizers, vulcanizers and other auxiliary materials according to product performance requirements, and then put the raw materials into a mixer for mixing, so that various materials are fully dispersed and form a uniform rubber compound. Next, the mixed rubber compound is passed through a calender to make a semi-finished tape with a certain thickness and width. Then, a layer of special self-adhesive coating liquid is applied on the surface of the semi-finished tape to give it good self-adhesiveness. Subsequently, the semi-finished tape with the self-adhesive coating liquid is placed in a vulcanizing tank for vulcanization reaction to cross-link and cure the rubber compound. Finally, the vulcanized and cured film is wound into a certain coiled finished product for subsequent storage.

[0004] After the self-adhesive coating liquid is applied to the surface of the semi-finished tape, a drying process is required to facilitate the subsequent vulcanization and curing reaction process. Therefore, a drying device is required for the surface of the semi-finished tape after the self-adhesive coating liquid is applied.

[0005] At present, in the existing drying device for the surface of the semi-finished tape after being coated with the self-adhesive coating liquid, when the semi-finished tape coated with the self-adhesive coating liquid is transported to the drying equipment for drying, a part of the liquid self-adhesive coating liquid that is not dried will directly drip onto the fixed plate before it is dried, causing waste.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

[0027] In detail, the left end of the semi-finished tape 22 is rolled on the unwinding group 21, and the right end of the semi-finished tape 22 passes through the feed port 11 and is rolled on the receiving group 3. The semi-finished tape 22 is an insulating silicone rubber self-adhesive tape that is not coated with a self-adhesive coating liquid.

[0028] Specifically, the support posts 63 are divided into two groups that are symmetrical on the left and right, and each group has two symmetrical posts. The lower ends of the support posts 63 are fixed to the fixing plate 2 to ensure the overall stability of the liquid receiving and recovery tray 6 .

[0029] Furthermore, the side cross-sections of the liquid receiving recovery tray 6 and the liquid guiding side guard plate 5 are both upward diffusion structures, and the right end face of the liquid receiving recovery tray 6 is fully welded and fixed to the left end face of the drying box 1. The liquid receiving recovery tray 6 can also store and recover the self-adhesive coating liquid dripping from the coating roller 41.

[0030] In more detail, there are two liquid-conducting side guard plates 5 that are symmetrical front and back, and a smoothing layer 51 is arranged on the inner wall surface of the liquid-conducting side guard plate 5. The smoothing layer 51 is made of a graphite powder density coating layer material and has a thickness of eighty to one hundred microns. The graphite powder density coating layer material has excellent smoothness, which further improves the ability to guide the dripping self-adhesive coating liquid into the liquid recovery plate 6.

[0031] Generally speaking, the liquid discharge pipe 7 is provided with a valve 71 , which is a manual valve.

[0032] The liquid guiding surface 60 is inclined toward the liquid discharge pipe 7 , and the angle between the liquid guiding surface 60 and the fixed plate 2 is three degrees, so that the flowing self-adhesive coating liquid will flow rapidly to the left along the inclined liquid guiding surface 60 .

[0033] Finally, the embedded cavity 61 is opened on the bottom inner wall of the liquid recovery plate 6, and the heating wire 62 is embedded in the embedded cavity 61. The heating wire 62 is a dry-burning type heating wire, which is durable and has high heating efficiency.

[0034] Working method: first pull the semi-finished tape 22 out from the preset unloading roller of the unloading group 21, pass through the feeding port 11 and be fixedly connected with the preset receiving roller of the receiving group 3 by bolts, then start the receiving motor 31, the coating motor 42 and the drying box 1, the receiving motor 31 drives the preset receiving roller of the receiving group 3 to rotate, so as to realize the feeding, movement and winding of the semi-finished tape 22 from left to right, at the same time, evenly coat the coating roller 41 with the self-adhesive coating liquid, and the coating motor 42 drives the coating roller 41 with the self-adhesive coating liquid to rotate on the surface of the semi-finished tape 22, and then the semi-finished tape 22 with the self-adhesive coating liquid enters the drying box 1 through the feeding port 11 for comprehensive drying, and the semi-finished tape 22 with the self-adhesive coating liquid after drying is wound on the preset receiving roller of the receiving group 3.

[0035] The above is the whole process of applying the self-adhesive coating liquid to the semi-finished tape 22 and discharging and collecting the materials. It is the prior art. Before the undried self-adhesive coating liquid on the semi-finished tape 22 enters the drying box 1 to the right, part of the self-adhesive coating liquid will drip downward into the liquid receiving recovery tray 6. At the same time, part of the self-adhesive coating liquid will also drip into the liquid receiving recovery tray 6 along the liquid guiding side guard plate 5, so as to realize the effective and comprehensive catching and recovery of the self-adhesive coating liquid dripping during the transportation of the semi-finished tape 22 to the feeding port 11, and avoid the waste of the self-adhesive coating liquid that has not been dried directly dripping onto the fixed plate 2.

[0036] In addition, when the liquid receiving and recovery tray 6 is full of dripping self-adhesive coating liquid, the left end of the drain pipe 7 is first connected to the external liquid storage barrel, and then the heating wire 62 and the valve 71 are opened. The heating wire 62 will heat the self-adhesive coating liquid stored in the liquid receiving and recovery tray 6 to ensure the flow state of the self-adhesive coating liquid. At this time, the flowing self-adhesive coating liquid will flow to the left along the inclined liquid guiding surface 60, and quickly flow into the externally connected liquid storage barrel through the drain pipe 7, so that the dripping self-adhesive coating liquid always remains in a flowing state, thereby ensuring the rapid liquid guiding, drainage and storage effect of the self-adhesive coating liquid in the later stage.
