Embodiment 1

[0021] like figure 1 , 2 As shown, the extrusion coating machine of this embodiment includes a storage tank 1, a screw pump 2, a coating head 3, a control unit and a substrate conveyor belt 4, and the coating head 3 passes through a height-adjustable bracket 5 Arranged above the substrate conveyor belt 4, the coating head 3 is provided with a coating chamber 31, the coating chamber 31 is provided with a feed port 32 and a discharge port 33, and the discharge port 33 is arranged at the top of the coating chamber 31 At the bottom, a pressure sensor is installed in the coating chamber 31; the substrate conveyor belt 4 is driven by a motor 6; the feed port 32 of the storage tank 1, the pump body and the coating chamber 31 is connected in sequence through pipelines, and the The pressure sensor, the screw pump 2, and the motor 6 are connected to the control unit (the control unit and the pressure sensor are not shown in the figure).

[0022] Further, the bottom surface of the feed...

Embodiment 2

[0027] like image 3 As shown, different from Embodiment 1, in this embodiment, the coating chamber of the coating head 3 is composed of a discharge chamber 312 and a feed chamber 311, and the feed port 32 is arranged at the end of the feed chamber 311. On the chamber wall, the discharge port 33 is arranged at the bottom of the discharge chamber 312; the discharge chamber 312 and the feed chamber 311 are communicated by several feed conduits 313, and the sum of the cross-sectional areas of the feed conduits 313 is smaller than the The cross-sectional area of ​​the feeding port 32 , the pressure sensor 7 is disposed in the feeding cavity 311 .

[0028] The paint enters the feed chamber 311 from the feed port 32 at first. Since the sum of the cross-sectional areas of the feed conduits 313 is less than the cross-sectional area of ​​the feed port 32, the paint will gradually fill the feed chamber 311, making the feed chamber 311 The pressure of the pump body is basically the same...

Abstract

The invention aims to provide an extrusion type coating machine so as to solve the problems of slurry layering and metamorphism and effectively improve the coating precision. The extrusion type coating machine provided by the invention comprises a storage tank, a pump body, a coating head, a control unit and a substrate conveying belt. The coating head is arranged over the substrate conveying belt, and is internally provided with a coating cavity, which is equipped with a feed inlet and a discharge port. The discharge port is disposed at the bottom of the coating cavity. The storage tank, the pump body and the feed inlet of the coating cavity are connected in order through a pipeline. The coating cavity is internally equipped with a pressure sensor. The pressure sensor and the pump body are connected to the control unit. The extrusion type coating machine provided by the invention changes the feeding mode and coating mode of traditional coating machines, the slurry can be always in a flow state, and has very short time to contact the air during coating, so that no packing effect can be generated, and a coating roll, a rubber roll or other parts are not needed. Therefore, the problems of slurry layering and metamorphism are solved, and the coating precision is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an extrusion coating machine. Background technique [0002] With the development of electric vehicle technology, people's requirements for the performance of lithium-ion power batteries for vehicles are also increasing, and the substrate coating process in battery production is directly related to the quality of battery performance. At present, most companies in China use transfer coating machines for coating. The trough-type storage and tube-type automatic feeding methods in transfer coating machines have the following disadvantages: [0003] 1. In the traditional automatic feeding process, the slurry needs to be piled up together. Under the action of the accumulation effect, the lighter components in the slurry will stay at the top of the cone, and the heavier components will move to the bottom of the cone first, so that The slurry is artificially ...
