Description

Technical Field

[0001] This utility model relates to the field of fiber cloth processing, and in particular to a fiber cloth coating device. Background Technology

[0002] In the fields of high-performance composite materials, high-temperature insulation materials, and building reinforcement materials, diabase fiber cloth is widely used in fireproofing materials, high-temperature filtration, pipe reinforcement, and industrial protection due to its excellent high-temperature resistance, chemical stability, tensile strength, and low thermal conductivity. In these applications, diabase fiber cloth typically requires impregnation with a resin to improve its interfacial bonding with the matrix resin, enhance its flexibility, or impart specific functions such as waterproofing, flame retardancy, and corrosion resistance.

[0003] Currently, the impregnation process for diabase fiber cloth mostly employs immersion coating equipment, consisting of a fixed glue tank and several guide rollers. The fiber cloth is continuously passed through the glue tank under tension to complete the coating. However, when starting up the equipment or changing the fiber cloth, it is necessary to manually pull the fiber cloth through the glue tank and through the subsequent guide roller system. This operation is cumbersome and can easily cause glue dripping or contamination. At the same time, during the process of changing the fiber cloth, the glue in the glue tank is exposed to the air for a long time, which can easily cause surface skinning, volatilization, or contamination, affecting the performance and lifespan of the glue. Therefore, a fiber cloth coating equipment is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0018] Example 1 like Figure 1-5 As shown, a fiber cloth coating device includes a glue tank 2 for holding glue liquid, and a gantry 1 set on the rear side of the glue tank 2. The gantry 1 has an overall "door" shaped frame structure, specifically including two vertical side plates on the left and right and a top crossbeam. A rotating and opening glue-impregnating roller assembly 3 is set on the gantry 1, which includes a rotating glue-impregnating roller 30 rotatably set on the front side of the gantry 1 and a rotating drive mechanism 31. The rotating drive mechanism 31 is used to drive the rotating glue-impregnating roller 30 to rotate. The rotating glue-impregnating roller 30 can press the horizontal fiber cloth into the glue tank 2 by rotating, or rotate in the opposite direction to move it above the horizontal fiber cloth. A glue-impregnating locking assembly 32 is also set on the front side of the gantry 1.

[0019] With this design, the rotating impregnation roller 30 can be driven to rotate by the rotating drive mechanism 31, so as to realize the controllable impregnation action of the fiber cloth, avoid the manual work of weaving the fiber cloth, and greatly improve its installation efficiency.

[0020] In the preferred embodiment, the cross-section of the glue tank 2 is a trapezoid with a wider top and a narrower bottom. This design can effectively reduce glue residue on the wall, facilitate cleaning and maintenance, and also facilitate the rotation of the dipping roller 30 to enter the tank by rotation.

[0021] In the preferred embodiment, the rotating dip roller 30 includes two rotating arms 301. Rotary bearings 102 are symmetrically arranged on the two side plates of the gantry 1. The rotating arms 301 are rotatably engaged with the corresponding rotary bearings 102 through the rotating shafts 303 at their ends, thereby enabling the rotating arms 301 to rotate around the rotating connection. The dip roller 302 is rotatably arranged between the other ends of the two rotating arms 301. The dip roller 302 is a metal or corrosion-resistant alloy roller. Each of the two rotating arms 301 is provided with a bearing for mounting the dip roller 302.

[0022] In this embodiment, the rotating arm 301 is bent, which makes it easier for the dip roller 302 to enter the corresponding position of the glue tank 2.

[0023] In the preferred embodiment, the front sides of both side plates of the gantry 1 are provided with extension plates 101 for mounting the rotary bearings 102, thereby providing sufficient installation space and rotational freedom for the rotary arm 301.

[0024] In the preferred embodiment, the rotary drive mechanism 31 consists of two rotary telescopic cylinders 310. The rotating end of the rotary arm 301 is provided with an extension hinge seat 304 that is hinged to the corresponding rotary telescopic cylinder 310. The other end of the rotary telescopic cylinder 310 is hinged to the gantry 1.

[0025] With this design, by controlling the extension and retraction of the rotary telescopic cylinder 310, the rotary arm 301 can be driven to reciprocate around the rotary bearing 102. When the rotary telescopic cylinder 310 extends, it pushes the rotary arm 301 to rotate downward, so that the impregnation roller 302 presses the horizontally running fiber cloth into the glue tank 2 to achieve impregnation. When the rotary telescopic cylinder 310 retracts, it drives the rotary arm 301 to flip upward, so that the impregnation roller 302 is removed from the glue tank 2 and the fiber cloth is lifted above the glue tank to achieve glue isolation in the non-working state.

[0026] It should be noted that both rotary telescopic cylinders 310 are hydraulic cylinders, and synchronous extension and retraction are achieved through a synchronous hydraulic system. This is existing technology, so it will not be described in detail here.

[0027] In the preferred embodiment, the impregnation locking assembly 32 includes two locking units, which are respectively located on the front side of the two side plates of the gantry 1 and below the rotating arm 301, thereby ensuring the stable working state of the rotating impregnation roller 30 in the glue tank 2 during the impregnation process and avoiding positional displacement caused by vibration or tension fluctuations.

[0028] In the preferred embodiment, the locking unit specifically includes a support base 321 for supporting the rotating arm 301 of the rotating dip roller 30 located in the glue tank 2. The outer side of the support base 321 is provided with an upwardly extending side wall 323. A horizontally arranged locking telescopic cylinder 324 is provided on the side wall 323. The telescopic end of the locking telescopic cylinder 324 can movably pass through the side wall 323. The outer side of the rotating arm 301 is provided with a pin hole 325 corresponding to the locking telescopic cylinder 324.

[0029] With this design, when the rotating arm 301 rotates to the dip position, the locking telescopic cylinder 324 extends, and its piston rod is inserted into the pin hole 325 to achieve mechanical locking and prevent the rotating dip roller 30 from accidentally springing back.

[0030] Furthermore, a second support 322 is provided between the bottom of the first support 321 and the side plate of the gantry 1 to enhance the overall structural rigidity.

[0031] In addition, a pressure sensor is embedded in the pin hole 325, which can abut against the locking telescopic cylinder 324. When the locking telescopic cylinder 324 is fully inserted and contacts the bottom of the pin hole, the pressure sensor senses the pressure signal and feeds it back to the control system to confirm that the locking is completed, thereby improving the automation and safety of the equipment.

[0032] Example 2 Further explanation in conjunction with Example 1, such as Figure 6-9 As shown in the structure, in order to control the thickness of the adhesive layer on the fiber cloth and improve the coating uniformity, the gantry 1 is also provided with a coating scraping mechanism 4, which includes a guide roller 40 rotatably disposed in the gantry 1, and an upper scraper assembly 41 and a lower scraper assembly 42 symmetrically arranged back and forth behind the guide roller 40.

[0033] The guide roller 40 is located behind the rotating and opening impregnation roller assembly 3. It is used to guide the impregnated fiber cloth to smoothly enter the subsequent upper scraper assembly 41 and lower scraper assembly 42, avoiding excessive contact with the lower scraper assembly 42, which could lead to breakage. The upper scraper assembly 41 and lower scraper assembly 42 are used to scrape off excess glue from the upper and lower surfaces of the fiber cloth, respectively, to achieve double-sided flattening control.

[0034] In the preferred embodiment, the upper scraper assembly 41 and the lower scraper assembly 42 have the same structure, both including two lifting mechanisms 410 and a blade body 411 that is driven between the two lifting mechanisms 410.

[0035] Two lifting mechanisms 410 are symmetrically arranged on the two side plates of the gantry 1. Each lifting mechanism 410 includes a U-shaped seat 4101, which is tilted to the side. Two lifting uprights 4102 are provided in the U-shaped base 4101. Lifting seats 4103 are slidably fitted on the outside of the lifting uprights 4102. A lifting telescopic cylinder 4104 is installed on the outside of the U-shaped base 4101. The telescopic end of the lifting telescopic cylinder 4104 moves through the U-shaped base 4101 and is connected to the lifting seat 4103. The blade body 411 is located between the lifting seats 4103 of the two lifting mechanisms 410.

[0036] With this design, by controlling the extension and retraction stroke of the lifting telescopic cylinder 4104, the contact relationship between the blade body 411 and the fiber cloth can be precisely adjusted, thereby adapting to fiber cloths of different thicknesses or adhesives of different viscosities, and achieving precise control of the coating amount.

[0037] In this embodiment, the blade body 411 includes a rod body disposed between two lifting seats 4103, and a scraper disposed outside the rod body and facing the direction of the fiber cloth. The scraper is preferably made of stainless steel or ceramic, with straight and sharp edges to ensure uniform glue application.

[0038] It should be noted that the lifting telescopic cylinder 4104 can be an electric telescopic rod, and is also equipped with a synchronous electric control system, so as to realize synchronous telescopic control between the two lifting telescopic cylinders 4104. This is existing technology, so it will not be described in detail here.

[0039] During operation, the equipment initially operates with the rotary opening and closing dip roller assembly 3 in a raised position, and the dip roller 302 positioned above the fiber cloth's running path. Once the fiber cloth is threaded, the control system activates the rotary telescopic cylinder 310, pushing the rotating arm 301 downwards to press the fiber cloth into the glue tank 2 for dipping. Subsequently, the locking telescopic cylinder 324 engages, inserting into the pin hole 325 for mechanical locking. The fiber cloth continues to run under traction, and after dipping, it enters the coating and leveling mechanism 4. The glue layer thickness is adjusted by the upper and lower scraper assemblies, and finally output to subsequent processes. When the machine stops or the cloth breaks, the locking telescopic cylinder 324 retracts, the rotary telescopic cylinder 310 retracts, and the rotating arm 301 flips upwards, causing the dip roller 302 to detach from the glue solution, preventing glue contamination and skin formation.

[0040] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
