Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of corona treatment on the surface of PP plates, and more specifically, to a corona treatment machine. Background Art
[0002] PP sheet, also known as polypropylene (PP) sheet (PP pure sheet, modified PP sheet, reinforced PP sheet, PP welding rod), is a semi-crystalline material. It is harder and has a higher melting point than PE. Since homopolymer PP is very brittle when the temperature is above 0°C, many commercial PP materials are random copolymers with 1-4% ethylene or clamp copolymers with higher ethylene content.
[0003] Corona treatment is an electric shock treatment that makes the surface of the substrate have higher adhesion. Most plastic films (such as polyolefin films) are non-polar polymers with low surface tension. Known inks and adhesives cannot adhere firmly to them. Therefore, the surface must be treated with corona to break the chemical bonds of the plastic molecules and degrade them. A large amount of ozone will also be generated during discharge. Ozone is a strong oxidant that can oxidize plastic molecules and produce highly polar groups such as carbonyl and peroxide, thereby increasing its surface energy.
[0004] The current corona treatment machine does not produce uniform and dense corona effects on the surface of PP plates, and there are too many blank areas. In some cases, this will have a significant impact on subsequent treatments such as lamination. Utility Model Content
[0005] The utility model aims to provide a corona treatment machine, which is a corona treatment machine capable of achieving uniform and intensive travel corona effect.
[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a corona treatment machine comprises a box body, a transmission component, a corona component and a heating component.
[0007] The box body includes a feed inlet and a discharge outlet;
[0008] The transmission component is arranged on the bottom of the inner wall of the box;
[0009] The corona assembly comprises a rotating motor and a corona bar, wherein the rotating motor is arranged outside the top surface of the box body, the output end of the rotating motor extends into the box body, one end of the rotating motor extending into the box body is provided with a corona bar, and a side of the corona bar away from the output end of the rotating motor is provided with a plurality of electrode disks spaced apart from each other;
[0010] The dust removal and heating component comprises a dust removal pipe arranged at the feeding port of the box body, and a plurality of PTC heating sheets for heating the surface of the PP board are arranged at one end of the dust removal pipe away from the inner wall of the box body.
[0011] Through the dust removal and heating component, the dust and PP board temperature that weaken the corona effect can be controlled under certain conditions. The setting of multiple electrode disks can ensure that a large area of corona treatment can be achieved simultaneously. By connecting multiple electrode disks through corona strips, a more uniform and denser corona effect can be achieved when the corona strips rotate.
[0012] The utility model is further configured as follows: the corona strip is provided with a plurality of electrode disks arranged along its axial direction.
[0013] Arranging a number of electrode disks on the corona bar can most directly increase the corona coverage area, thereby increasing the production speed and speeding up the operation.
[0014] The utility model is further configured as follows: a plurality of electrode disks are arranged at uneven intervals.
[0015] The electrode disks arranged at uneven intervals can cover a larger area. Compared with the electrode disks arranged at even intervals, the electrode disks arranged at even intervals have uniform incomplete coverage, and in some cases the corona effect will fail. However, the uneven interval arrangement has multiple motion trajectories that are different from a single regularity, thereby achieving multiple regular and more complex corona trajectories, resulting in a better corona effect. Compared with the uniform arrangement, the corona effect can be achieved more stably.
[0016] The utility model is further configured as follows: the electrode disk is detachably connected to the corona strip.
[0017] The electrode disks and the corona strips are detachable, and different numbers of electrode disks can be selected according to the corona effect, thereby achieving a more regular, uniform and dense corona trajectory.
[0018] The utility model is further configured as follows: a plurality of slots are arranged on the corona strip.
[0019] The mounting of the electrode disc can be assisted by the clamping groove.
[0020] The utility model is further configured as follows: a plurality of conductor electrodes arranged in a circumferential array and evenly arranged are arranged on one side of the electrode disk, and a mounting piece corresponding to the slot is arranged on a side of the electrode disk away from the conductor electrodes.
[0021] The installation with the card slot can be realized through the correspondingly arranged installation parts, and a uniform corona effect can be formed through the uniform arrangement of the conductor electrodes.
[0022] The utility model is further configured as follows: a side of the electrode disk away from the mounting piece is provided with a plurality of back ribs in a circumferential array, a plurality of mounting grooves are opened on the back ribs, and a main electrode is provided at the intersection of the plurality of back ribs.
[0023] The conductor electrode is installed by setting the installation groove on the back rib.
[0024] The utility model is further configured as follows: a positioning notch is arranged on the side of the mounting piece.
[0025] The electrode disk can be disassembled and assembled more quickly by setting the positioning notch.
[0026] In summary, the utility model has the following beneficial effects: through the dust removal and heating component, the dust with weakened corona effect and the temperature of the PP board can be controlled under certain conditions, and through the setting of multiple electrode disks, it can ensure that a large area of corona treatment is achieved at the same time, and through the corona bar, connecting multiple electrode disks can achieve a more uniform and denser corona effect when the corona bar rotates.
