Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a cloth coating device. Background Art

[0002] Coated cloth mainly refers to a layer of material with special functions coated on the basis of cloth using a special process, so that the cloth has special functions, such as flame retardant, waterproof, UV resistance, etc. In the existing production process, the cloth is often coated by spraying solvent. This method has high coating efficiency and uniform coating effect, but for cloth with higher waterproof grade requirements, it is difficult for waterproof solvent to enter and adhere to the tissue structure of the cloth. As a result, once the cloth is pulled hard during use, water can easily pass through the tissue structure of the cloth, causing the cloth to partially lose its waterproof function.

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-4As shown, a cloth coating device includes a frame 10 and a heater, a sprayer 3, an expansion guide roller 2, and a motor 7 installed on the frame 10. The heater can preheat the cloth 11 to make it softer and easier to stretch, and also make the coating easier to adhere to the cloth 11. The expansion guide roller 2 is connected to the motor 7 in a transmission manner. The expansion guide roller 2 can stretch the cloth 11 laterally. There are two sprayers 3 and expansion guide rollers 2 and they are located at the right end of the heater. The two sprayers 3 are arranged opposite to each other up and down, and can perform double-sided coating operations on the cloth 11. The two expansion guide rollers 2 are arranged up and down at the left and right ends of the two sprayers 3, so that the cloth 11 between the two expansion guide rollers 2 is evenly coated. The expansion guide roller 2 is evenly stretched to ensure that the coating can enter between the tissue structures of the cloth 11 and enhance the coating effect. An expansion thread 201 is provided on the expansion guide roller 2. The expansion thread 201 spirally extends clockwise from the middle of the expansion guide roller 2 to the front end and the rear end respectively. The expansion guide roller 2 rotates counterclockwise. At the contact point between the cloth 11 and the expansion guide roller 2, the traveling direction of the cloth 11 is opposite to the rotation direction of the expansion guide roller 2, so that the relative movement speed between the cloth 11 and the expansion guide roller 2 is accelerated, thereby accelerating the lateral relative movement speed between the expansion thread 201 and the cloth 11, thereby realizing rapid stretching of the cloth 11 to adapt to the high-speed traveling cloth 11 and improve coating efficiency.

[0019] In the above embodiment, the heater is two heating plates 1 arranged up and down, which can not only quickly preheat the front and back sides of the cloth 11, but also make the cloth 11 heated evenly, which is conducive to the adhesion of the coating; the heating plates 1 are connected by a synchronous adjustment structure 4, and the spacing between the heating plates 1 can be adjusted according to the thickness of the cloth 11 to avoid the heating plates 1 clamping the cloth 11 too tightly, and to avoid the gap between the heating plates 1 and the cloth 11 being too large, so as to ensure that the heat of the heating plates 1 can be efficiently transferred to the cloth 11, and the synchronous adjustment structure 4 can be a structure in which the two ends of the synchronous gear 5 are respectively meshed with the rack, and the rack is respectively connected to the upper and lower heating plates 1, and the heating plates 1 are clamped and loosened by the rotation of the synchronous gear 5; the frame 10 is provided with a lateral adjustment structure, and the motor 7 is installed on the lateral adjustment structure, which can be appropriately adjusted according to the unwinding position, size and model of the cloth 11 to ensure The expansion guide roller 2 is always located in the middle of the cloth 11, thereby ensuring the symmetry of the expansion guide roller 2 when stretching the cloth 11. The lateral adjustment structure can be a screw 9, a nut seat 8, etc. The motor 7 is installed on the nut seat 8, the screw 9 and the nut seat 8 are connected by threads, and the screw 9 is rotatably connected to the frame 10. The position of the nut seat 8 can be adjusted by rotating the screw 9, and the adjustment is convenient and accurate; the pitch of the expansion thread 201 gradually increases from the middle of the expansion guide roller 2 to the front and rear ends, and the stretching frequency of the expansion guide roller 2 on the cloth 11 gradually decreases from the middle to the two ends. Combined with the fact that the deformation resistance of the middle structure of the cloth 11 is better than that of the edge structure, the overall deformation of the cloth 11 tends to be average when it is stretched, so that the coating is more uniform; the two sprayers 3 are located on the same vertical plane, and the coating is carried out in a counter-attack manner to avoid repeated spraying at the same position due to the sprayers 3 being one in front and one behind, thereby ensuring the uniformity of the coating.

[0020] Description of the working method of this utility model:

[0021] The cloth 11 enters from the left end of the device and enters between the two heating plates 1. Under the preheating of the heating plates 1, the cloth 11 gradually becomes softer and easier to stretch. Then the cloth 11 enters between the two expansion guide rollers 2. Under the action of the expansion guide rollers 2, the cloth 11 is stretched from the middle to the front and rear ends by the expansion threads 201, and the two expansion guide rollers 2 arranged on the left and right ensure that the cloth 11 therebetween always remains in a stretched state and will not shrink quickly, providing favorable conditions for coating; after the cloth 11 is evenly pulled apart, the sprayers 3 arranged in opposite directions up and down perform bidirectional coating on the cloth 11 therebetween, so that the coating can not only be coated on the surface of the cloth 11, but also between the tissue structures of the cloth 11, thereby enhancing the coating effect; after the coating is completed, the cloth 11 leaves the expansion guide rollers 2, and then the cloth 11 shrinks and is rolled up.

[0022] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
