Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a uniform coating equipment for composite material bonding coating. Background Technology

[0002] Composite materials, especially high-performance composite materials, are widely used in aerospace, automobile manufacturing and wind power generation. The bonding process in their production is crucial and directly affects the structural strength and reliability of the final product. Before bonding, a bonding coating of a specific thickness is usually uniformly applied to the surface of the composite substrate.

[0003] Currently, most coating equipment on the market relies on the operator's experience to control the opening of the discharge valve when applying adhesive coatings. The flow rate of the coating material will change due to changes in the liquid level in the material box or fluctuations in the viscosity of the coating material itself. This unstable flow rate makes it difficult to maintain a consistent coating thickness, which seriously affects the uniformity of product quality.

[0004] Although some equipment attempts to introduce mechanical structures to fix the opening of the discharge port, these structures are often relatively simple and lack an effective locking mechanism. Under the action of equipment vibration or the reverse pressure of the coating material, the valve opening is prone to slight changes. Over a long period of operation, this accumulated error will still lead to inaccurate flow control.

[0005] Therefore, this utility model proposes a composite material bonding coating uniform coating device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of unstable coating material flow, difficulty in precise control and lack of reliable locking mechanism in the existing composite material bonding coating uniform coating equipment, this utility model aims to provide a composite material bonding coating uniform coating equipment with improved structure that can effectively solve the above problems.

[0007] This utility model provides a uniform coating device for composite material bonding coating, comprising: a control mechanism, the control mechanism including a body, a heating plate, a slide groove and a sliding arm, the sliding arm being fixedly connected to an adjustment component and a flow control mechanism, the adjustment component including a first coating wheel and a second coating wheel; and the flow control mechanism including a glue box, a sealing column, a rack, a handle and a gear.

[0008] The flow control mechanism is also specially designed with a sloping plate. The sloping front end of the sloping plate matches the sloping tooth surface of the gear, and the straight back surface of the sloping plate abuts against the straight tooth end surface of the gear.

[0009] Furthermore, the sealing post is movably connected inside the outlet of the glue box. The sealing post is fixedly connected to the rack, the gear meshes with the rack, the handle is rotatably connected to the gear, and the inclined plate is hinged to the outer wall of the glue box. Through the one-way meshing and abutting action between the inclined plate and the gear, the mechanical self-locking of the opening height of the sealing post is achieved, thereby ensuring the stable and controllable flow rate of the coating material.

[0010] Preferably, the adjustment assembly further includes a limiting post, a lifting block, and a first screw. The limiting post is fixedly connected to the sliding arm, the lifting block is slidably fitted to the outer wall of the limiting post, the first coating wheel and the second coating wheel are both rotatably connected to the lifting block, and the first screw is threadedly fitted to the lifting block to control the lifting block to move up and down along the limiting post, thereby achieving precise adjustment of the coating height.

[0011] Preferably, the adjustment assembly further includes a sliding block and a second screw. The sliding block is slidably connected to the side of the lifting block, the first coating wheel is rotatably connected to the end of the sliding block, and the second screw is threadedly engaged with the sliding block. By rotating the second screw, the gap between the first coating wheel and the second coating wheel can be adjusted to achieve precise control of the coating thickness.

[0012] Preferably, the inclined surface of the inclined plate is used to be pressed by the tooth end of the gear when the gear rotates upward, so that the inclined plate moves upward. The inclined plate falls down and meshes with the gear when the gear rotates to the tooth gap with the help of gravity. This structural design simplifies the mechanical structure and improves the long-term reliability of the locking mechanism.

[0013] Preferably, the control mechanism further includes a display screen and a control board, both of which are fixedly connected to the outside of the machine body for operation and status monitoring of the equipment, making equipment control more intuitive and convenient.

[0014] Preferably, the machine body is further provided with a motor, which is electrically connected to the control board and is used to drive the sliding arm to move back and forth in the slide groove to achieve automated uniform coating and improve production efficiency and coating quality consistency.

[0015] Preferably, the second coating wheel is rotatably connected to the lifting block, which further clarifies the assembly relationship of the adjustment components and makes the structural hierarchy clearer.

[0016] Preferably, the heating plate is located below the first coating wheel and the second coating wheel. This positional relationship ensures that the material to be coated can be fully preheated before coating, thus meeting the process requirements of the specific material.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section.

[0018] 1. This utility model, by setting an adjustment component, uses the first screw to adjust the up and down movement of the lifting block to control the overall height of the coating wheel, and uses the second screw to adjust the back and forth movement of the sliding block to control the gap between the two coating wheels.

[0019] 2. This utility model, by setting a flow control mechanism, uses a rotary handle to drive a gear and rack mechanism to control the lifting and lowering of the sealing column, and uses a sloping plate that cooperates with the gear to achieve one-way mechanical locking, solves the problem of unstable flow caused by changes in the gravity or pressure of the coating material in the prior art, and achieves the technical effect of being able to accurately set and stably maintain the flow of the coating material.

[0020] 3. This utility model solves the problem of difficulty in ensuring uniformity in manual coating or simple mechanical movement in the prior art by fixing the adjustment component and flow control mechanism as a whole on the sliding arm that moves in the slide groove, and driving the adjustment component and flow control mechanism to reciprocate as a whole by a motor. It achieves the technical effect of being able to fully cover, uniformly and evenly coat large-area composite material substrates. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 5 As shown in the figure, this utility model provides a composite material bonding coating uniform coating device, which aims to solve the problems of difficulty in accurately adjusting the coating thickness and height, unstable coating material flow rate and uneven coating movement in the prior art.

[0030] like Figure 1 As shown, the composite material bonding coating uniform coating equipment includes a control mechanism 1. The control mechanism 1 includes a body 101 as a basic installation platform. A heating plate 105 is fixedly connected inside the body 101. Slide grooves 104 are provided on the inner walls of both sides of the body 101 for the reciprocating movement of sliding arms 106. The sliding arms 106 are slidably fitted in the slide grooves 104. An adjustment component 2 and a flow control mechanism 3 are fixedly connected to the sliding arms 106. In order to realize automated control, a display screen 102 and a control board 103 are also fixedly connected to the outside of the body 101. A motor electrically connected to the control board 103 is provided inside the body 101. The motor is used as a power source to drive the sliding arms 106 to move along the slide grooves 104.

[0031] like Figure 1 and Figure 3As shown, the adjustment component 2 is used to precisely adjust the coating height and thickness. It includes a limiting post 202, a lifting block 201, a first screw 203, a sliding block 204, a second screw 207, a first coating wheel 205, and a second coating wheel 206. The limiting post 202 is fixedly connected to the top of the sliding arm 106. The lifting block 201 is slidably fitted to the outer wall of the limiting post 202. The first screw 203 is threadedly fitted to the lifting block 201 to control the up and down movement of the lifting block 201. The second coating wheel 206 is rotatably connected to the lifting block 201. At the same time, the sliding block 204 is slidably connected to the side of the lifting block 201. The second screw 207 is threadedly fitted to the sliding block 204 to control the back and forth movement of the sliding block 204. The first coating wheel 205 is rotatably connected to the end of the sliding block 204. Through this double-screw adjustment structure, precise control of the overall height of the coating wheel and the gap between the two wheels can be achieved.

[0032] like Figure 4 and Figure 5 As shown, the flow control mechanism 3 is used to stably control the flow rate of the coating material. It includes a glue box 301, a sealing post 306 is movably connected inside the outlet of the glue box 301, the sealing post 306 is fixedly connected to the rack 302, and a gear 304 that meshes with the rack 302 is rotatably connected inside the glue box 301. A handle 303 passing through the glue box 301 is rotatably connected to the gear 304. To achieve one-way locking, a sloping plate 305 is hinged to the outer wall of the glue box 301. The sloping surface at the front end of the sloping plate 305 engages with the sloping surface of the gear 304, and the straight surface on the back of the sloping plate 305 engages with the straight surface of the gear 304. When the gear 304 rotates in the forward direction, the sloping plate 305 is lifted and falls into the next tooth space by gravity. When the gear 304 attempts to rotate in the reverse direction, it is locked by the straight surface of the sloping plate 305, thereby locking the opening height of the sealing post 306.

[0033] The working principle of the composite material bonding coating uniform coating device of this utility model is as follows:

[0034] First, the material to be processed is placed on the heating plate 105. The lifting block 201 is adjusted by rotating the first screw 203 to set the overall height of the coating wheel. Then, the sliding block 204 is adjusted by rotating the second screw 207 to set the gap between the first coating wheel 205 and the second coating wheel 206 to control the coating thickness.

[0035] Next, the coating material is added to the glue box 301, and the handle 303 is slowly rotated. The gear 304 drives the rack 302 and the sealing column 306 to move upward, opening the outlet and allowing the coating material to flow out. At this time, the inclined plate 305 cooperates with the gear 304 to achieve one-way locking, ensuring that the opening degree of the outlet is constant, thereby obtaining a stable coating material flow rate.

[0036] Finally, the motor is started by the control board 103. The motor drives the sliding arm 106 to move at a constant speed in the slide 104 with the adjustment component 2 and the flow control mechanism 3, so that the coating material from the glue box 301 is evenly coated onto the material surface on the heating plate 105 through the first coating wheel 205 and the second coating wheel 206.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
