Example 1

As shown in fig. 1, embodiment 1 provides a horizontal glue coater, which includes a frame, a steel roller 1, a glue roller 2, a scraper 3, and two carrier rollers 4.

The both ends pin joint of steel roller 1 is in the frame, and in this embodiment, steel roller 1 both ends pass through the bearing with the frame and fix. One end of the steel roller 1 is connected with a transmission system in a transmission way, such as a motor or a speed reducer. It should be noted that the pivot joint of the steel roller 1 and the frame and the transmission connection of the steel roller 1 and the transmission system are all the prior art means of the existing coating machine, and are not described too much here. The circumferential surface of the steel roller 1 is provided with reticulate patterns formed by uniformly distributed micropores. The micropores are conical concave holes, the mesh number of the micropores is more than or equal to 100 meshes, so that the micropores have a certain space for accommodating glue solution and are fine.

Two ends of the rubber roller 2 are pivoted to the frame, and two ends of the rubber roller 2 are fixed with the frame through bearings. Wherein, one end of the rubber roller 2 can be in transmission connection with a transmission system or not; when the rubber roller 2 is not connected with the transmission system, the steel roller 1 drives the metal belt 6, and the metal belt 6 drives the rubber roller 2 to make the rubber roller 2 rotate passively. The rubber roller 2 is arranged below the steel roller 1, and the rubber roller 2 is parallel to the axis of the steel roller 1. The rubber roller 2 can be arranged right below the steel roller 1, or can be arranged at the left lower side or the right lower side, but the rubber roller 2 is necessarily kept parallel to the steel roller 1. A gap for threading is arranged between the steel roller 1 and the rubber roller 2, and the gap is slightly smaller than the thickness of the metal belt 6, so that the steel roller 1 and the rubber roller 2 can clamp the metal belt 6. Wherein, the rubber roller 2 is a polyurethane roller with elasticity so as to enable the steel roller 1 and the rubber roller 2 to clamp the metal belt 6 better.

The scraper 3 is fixed on the frame, the edge of the scraper 3 contacts with the circumferential surface of the steel roller 1, the edge of the scraper 3 is parallel to the steel roller 1, and the scraper 3 and the circumferential surface of the steel roller 1 form a V-shaped included angle space 5.

The carrier roller 4 is pivoted to the frame, and the carrier roller 4 is arranged parallel to the steel roller 1. Two carrier rollers 4 are arranged, and the two carrier rollers 4 are respectively positioned at the upstream and the downstream of the gluing process of the steel roller 1 or the rubber roller 2; for example, one idler 4 is disposed on the left side of the rubber roller 2, and the other idler 4 is disposed on the right side of the rubber roller 2. The support rollers 4 serve to guide or support the metal belt 6. In the present exemplary embodiment, the upper edges of the two support rollers 4 and of the rubber roller 2 are in a plane, in order to keep the metal strip 6 flat during the gluing process.

Before gluing, the rolled metal belt 6 is penetrated into a gap between the steel roller 1 and the rubber roller 2. During gluing, glue solution is conveyed to an included angle space 5 formed between the scraper 3 and the steel rod through a guide pipe, wherein the glue solution is conveyed through another device of the gluing process. Along with the self-transmission of the steel roller 1 and the blade part action of the scraper 3, the glue solution fills each micropore passing through the blade part of the scraper 3. The metal belt 6 moves synchronously while the steel roller 1 is self-transmitting; since the gap is smaller than the thickness of the metal belt 6, the metal belt 6 is squeezed and compressed between the steel roller and the rubber roller 2. Under the extrusion action of the steel roller and the rubber roller 2, the side surface of the metal belt 6 close to the steel roller 1 is tightly attached to a certain position of the circumferential surface of the steel roller 1, and the glue solution is uniformly distributed on the surface of the metal belt 6; the micropores are evenly distributed, so that the glue solution is evenly distributed on the surface of the metal belt 6.

According to the glue coating machine, glue is coated through the micropores which are uniformly distributed, so that the glue is more uniformly coated; the glue coating amount is limited by the volume and the number of the micropores, so that the metering is more accurate; when gluing, only need with liquid glue carry contained angle space 5 can, need not carry out the glue transport through other rollers, easy operation. Compared with a fog type coating machine, the glue coating machine of the embodiment has more uniform glue coating; compared with a gap type coating machine, the requirement on the purity of glue solution is reduced, even if the glue blocks in the particle shape exist, the glue blocks can be crushed by the scraper 3, and linear missing coating caused by blockage can not occur; compared with a roller type transfer coating machine, the roller type transfer coating machine does not need a metering roller, a transfer roller and the like, and has a simpler structure; compared with a scraper 3 type coating machine, the glue solution is carried to the surface of the metal belt 6 through the micropores, no included angle gap exists, the influence of sundries does not need to be worried, the gluing amount is limited through the micropores, the gluing is uniform, and the metering is accurate.

In the embodiment, in order to prevent the glue solution from thickening due to cooling, the steel roller 1 has a heating function, and a heating steel roller in the prior art is generally adopted; meanwhile, the scraper 3 also has a heating function, and a heating scraper in the prior art is adopted.

As shown in fig. 2, embodiment 2 provides a vertical glue coater, which includes a frame, a steel roller 1, a glue roller 2, a scraper 3, and two carrier rollers 4.

Two ends of the rubber roller 2 are pivoted to the frame, and two ends of the rubber roller 2 are fixed with the frame through bearings. Wherein, one end of the rubber roller 2 can be in transmission connection with a transmission system or not; when the rubber roller 2 is not connected with the transmission system, the steel roller 1 drives the metal belt 6, and the metal belt 6 drives the rubber roller 2 to make the rubber roller 2 rotate passively. The rubber roller 2 is arranged on the left side or the right side of the rubber roller 2, and the rubber roller 2 is parallel to the axis of the steel roller 1. In this embodiment, the rubber roller 2 is arranged on the left side of the steel roller 1. A gap for threading is arranged between the steel roller 1 and the rubber roller 2, and the gap is slightly smaller than the thickness of the metal belt 6, so that the steel roller 1 and the rubber roller 2 can clamp the metal belt 6. Wherein, the rubber roller 2 is a polyurethane roller with elasticity so as to enable the steel roller 1 and the rubber roller 2 to clamp the metal belt 6 better.

The carrier roller 4 is pivoted to the frame, and the carrier roller 4 is arranged parallel to the steel roller 1. Two carrier rollers 4 are arranged, and the two carrier rollers 4 are respectively positioned at the upstream and the downstream of the gluing process of the steel roller 1 or the rubber roller 2; for example, one idler 4 is disposed below the rubber roller 2, and the other idler 4 is disposed above the rubber roller 2.
