Description

Technical Field

[0001] This utility model belongs to the field of coating technology for wire mesh rollers, and specifically relates to a closed scraper mechanism for a wire mesh roller coating unit. Background Technology

[0002] Currently, most composite mechanical equipment's mesh roller coating units still use an open glue tank equipped with an adjustable scraper. This mechanism has the following problems: the open glue tank and scraper need to be connected and installed separately to the wall panel, lacking an integrated design concept; the immersion-type glue application and scraper-scraping mode result in high glue and solvent consumption, leading to increased costs and resource waste; the open glue tank has a high evaporation rate, and glue is easily splashed during application, causing environmental pollution, increased viscosity, etc., which does not meet workshop environmental protection requirements and is detrimental to the occupational health of operators; some mesh roller coating units use a closed scraper mechanism with cylinder clamping. This mechanism has the following problems: unstable air pressure directly affects the scraping effect, the scraper is easily damaged, the mesh roller is easily scratched, and the direct-pressure structure makes cylinder placement inconvenient, reducing the space utilization rate of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a closed scraper mechanism for a coating unit of a screen roller, which solves the technical problem that the screen roller is easily scratched because the screen roller coating unit uses a closed scraper mechanism with a cylinder for pressing.

[0004] The technical solution adopted in this utility model is a closed scraper mechanism for a wire mesh roller coating unit, including a cavity assembly; the cavity assembly includes a C-shaped cavity, the cavity is connected to a return pipe and a feed pipe, a cavity support is installed on the side wall near both ends of the cavity, a roller shaft is installed on the cavity support, and both roller shafts are connected to a limit assembly; a scraper clamp is installed on the top edge and bottom edge of the cavity opening side, a scraper blade is installed on the scraper clamp, and a glue baffle is installed at both ends of the cavity opening side, and the cavity and the glue baffle are connected by a glue baffle pressure plate.

[0005] The features of this utility model also include:

[0006] A handle and a return tube bracket are installed on the side wall of the cavity away from the outlet, and the return tube is installed on the return tube bracket.

[0007] The limiting assembly includes a connecting plate, on which an upper slide rail and a lower slide rail are slidably connected. A quick clamping device and a fine-tuning device are installed through the upper slide rail. A mounting cavity for installing a roller shaft is formed between the quick clamping device, the fine-tuning device, the upper slide rail, and the lower slide rail. A limiting block and a U-shaped groove are sequentially installed on the side wall of the connecting plate in a direction away from the upper slide rail. The upper slide rail, the limiting block, and the U-shaped groove are connected by a first screw.

[0008] A connecting bracket is installed on the side wall of the connecting plate opposite to the upper and lower slide rails, and an adjusting pad is connected between the connecting bracket and the connecting plate.

[0009] The quick-clamping device includes a second support, inside which a connecting shaft and a second screw are threaded together. A second spacer is fitted onto the top of the second screw, and a second pressure tongue is fitted onto the bottom of the second screw. The second screw and the second pressure tongue are connected by a second pin. A second spring is installed between the second spacer and the second pressure tongue. The side of the second spacer facing away from the second spring abuts against the connecting shaft. The end of the connecting shaft facing away from the second screw extends out of the second support, and a hinge clamp is connected to the end of the connecting shaft extending out of the second support. The hinge clamp is also hinged to a handle for controlling the linear movement of the connecting shaft in the second spacer. The bottom of the second pressure tongue is provided with an inclined surface, which faces the fine-tuning device.

[0010] A second composite bushing is installed between the second screw and the second pressure tongue.

[0011] The fine-tuning device includes a knob and a third support that are nested together. A third screw is inserted through the third support. One end of the third screw extends into the knob. A screw is inserted through the top of the knob and is threadedly connected to the third screw. A pin is inserted through the side wall of the knob to make the third screw and the knob rotate synchronously.

[0012] The third screw is threaded to the end opposite to the knob with a third pressure tongue. The upper slide rail has a through groove, and a pin is provided in the groove to restrict the rotation of the third support and the third pressure tongue. The bottom of the third pressure tongue has an inclined surface, which faces the quick clamping device.

[0013] A third composite bushing in the shape of an inverted T is installed between the third screw and the third support. The third screw is circumferentially fitted with a third spacer, and the bottom of the third composite bushing is connected to the top of the third spacer.

[0014] The third support has two blind holes along a direction parallel to the axis. A third spring is installed in the blind holes, and a steel ball is installed on the top of the third spring. The bottom of the knob has several spherical holes that mate with the steel ball.

[0015] The scraper blade has a horizontal angle of 96°.

[0016] The beneficial effects of this utility model are:

[0017] The scraper mechanism of this utility model adopts the form of inclined pressure rollers for front and rear limit. The front end is finely adjusted by a threaded pair, and the rear end is pressed by a hinge clamp and a spring. The position of the scraper is locked mechanically. The scraper exerts less pressure on the screen roller in cross-section, which greatly reduces the wear of the scraper and screen roller while scraping off the glue, effectively reducing operation and maintenance costs.

[0018] This utility model features a combined design of the cavity and the scraper, employing a bottom-in, top-out circulating glue supply mode. In practical applications, viscosity detection and control can be incorporated into the glue circulation to achieve intelligent control of glue viscosity. At the same time, the scraper position is locked mechanically, resulting in a compact spatial arrangement and improved space utilization of the equipment. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Example 1

[0036] like Figure 1-7 As shown, the closed scraper mechanism for a wire mesh roller coating unit disclosed in this utility model includes a cavity assembly 1; the cavity assembly 1 includes a C-shaped cavity 1-3, the cavity 1-3 is connected to a return glue pipe 1-5 and a glue inlet pipe 1-7, a cavity bracket is installed on the side wall near both ends of the cavity 1-3, a roller shaft 1-1 is installed on the cavity bracket, and both roller shafts 1-1 are connected to limit components; a scraper clamp 1-11 is installed on the top edge and bottom edge of the opening side of the cavity 1-3, a scraper blade 1-12 is installed on the scraper clamp 1-11, and glue baffles 1-10 are installed at both ends of the opening side of the cavity 1-3, and the cavity 1-3 and the glue baffles 1-10 are connected by a glue baffle pressure plate 1-9.

[0037] In this embodiment, the limiting components include M-side limiting component 2 and G-side limiting component 3. M-side limiting component 2 and G-side limiting component 3 are mirror images of each other, and both are used for sliding support and limiting fixation of cavity component 1. The cavity support includes G-side cavity support 1-2 and M-side cavity support 1-8. The roller shaft 1-1 on G-side cavity support 1-2 and M-side cavity support 1-8 is inserted between M-side limiting component 2 and G-side limiting component 3 to complete the assembly, which is used for the front and back sliding of cavity component 1. The scraper blades 1-12 on the upper and lower sides and the glue baffles 1-10 on the left and right sides press against the surface of the screen roller, achieving the effect of storing glue in the inner cavity of the scraper mechanism and isolating it from the air. The scraper blades 1-12 play a dual role of sealing and scraping glue. The cavity is designed with 5A05 aluminum alloy material to meet the requirements of strength and lightweight. The surface is coated with Teflon to meet the harsh operating environment of solvent corrosion and extreme pH value, and it is easier to clean. The inner wall of the cavity is smooth and the cross-sectional curve is gentle, which optimizes the consistency of glue flow. In this embodiment, the roller shaft 1-1 has a T-shaped structure and uses two cylindrical wheels connected to the limiting component.

[0038] Example 2

[0039] Based on Embodiment 1, a handle 1-4 and a return tube bracket 1-6 are installed on the side wall of the cavity 1-3 away from the outlet side. The return tube 1-5 is installed on the return tube bracket 1-6. The handle 1-4 is used to pull the cavity assembly 1 backward as a whole, which facilitates blade replacement and cavity cleaning. The return tube 1-5 is fixed on the return tube bracket 1-6 to ensure that the return tube is unobstructed.

[0040] In this embodiment, the return tube 1-5 is used for circulating glue supply to the cavity 1-3.

[0041] Example 3

[0042] like Figure 8 and Figure 9 As shown, based on Embodiment 1, the limiting component includes a connecting plate 2-3. An upper slide rail 2-8 and a lower slide rail 2-4 are slidably connected to the side wall of the connecting plate 2-3. A quick clamping device 2-9 and a fine-tuning device 2-10 are installed through the upper slide rail 2-8. A mounting cavity for installing the roller shaft 1-1 is formed between the quick clamping device 2-9, the fine-tuning device 2-10, the upper slide rail 2-8, and the lower slide rail 2-4. A limiting block 2-7 and a U-shaped groove are sequentially installed on the side wall of the connecting plate 2-3 in a direction away from the upper slide rail 2-8. The upper slide rail 2-8, the limiting block 2-7, and the U-shaped groove 2-5 are connected by a first screw 2-6.

[0043] In this embodiment, a U-shaped groove 2-5 is provided at the rear end to support the roller shaft 1-1 when the cavity assembly 1 is pulled out backward, allowing the cavity assembly 1 to rotate at a certain angle for easy blade replacement and cavity cleaning. Specifically, by rotating the limiting block 2-7 upward around the screw 2-6 and lifting the hinge clamp 2-9-1, the cavity assembly 1 can be pulled out backward as a whole through the handle 1-4. At this time, the U-shaped groove 2-5 is used to support the roller shaft 1-1 (one cylindrical wheel is located in the U-shaped groove, and the other cylindrical wheel is located in the mounting cavity). The cavity assembly 1 can rotate and tilt at a certain angle for easy cleaning of the working surface. The upper slide rail 2-8 includes first assembling the quick clamping device 2-9 and the fine adjustment device 2-10 on the upper slide rail 2-8, then assembling this component together with the connecting bracket 2-1, the lower slide rail 2-4, and the U-shaped groove 2-5 on the connecting plate 2-3, and finally assembling the adjusting pad 2-2, the screw 2-6, and the limiting block 2-7. The connecting hole on the connecting plate 2-3 and the connecting bracket 2-1 is a strip-shaped hole, which allows for preliminary adjustment of the vertical position of the cavity assembly 1 during assembly; the connecting hole on the connecting plate 2-3 and the upper slide rail 2-8 is also a strip-shaped hole, which allows for preliminary adjustment of the front and rear position of the cavity assembly 1, thereby ensuring the parallelism requirements of the cavity assembly 1 and the wire roller.

[0044] Furthermore, a connecting bracket 2-1 is installed on the other side wall of the connecting plate 2-3 opposite to the upper slide rail 2-8 and the lower slide rail 2-4. An adjusting pad 2-2 is connected between the connecting bracket 2-1 and the connecting plate 2-3. The connecting plate 2-3, the upper slide rail 2-8, and the lower slide rail 2-4 limit the movement of the roller shaft 1-1, allowing the roller shaft 1-1 to move back and forth only between the upper and lower slide rails. Therefore, only the back and forth limit of the roller shaft 1-1 is needed to fix the position of the entire cavity assembly 1. The connecting bracket 2-1 is used to connect the entire enclosed scraper system to the wall panel. The adjusting pad 2-2 is used for the horizontal adjustment of the cavity assembly 1 in all directions, thereby ensuring the levelness requirement of the cavity assembly 1.

[0045] Example 4

[0046] like Figure 10 and Figure 11As shown, based on Embodiment 3, the quick clamping device 2-9 includes a second support 2-9-2. A connecting shaft and a second screw 2-9-5, threadedly connected to each other, are sleeved inside the second support 2-9-2. A second spacer 2-9-3 is sleeved on the top of the second screw 2-9-5, and a second pressure tongue 2-9-8 is sleeved on the bottom of the second screw 2-9-5. The second screw 2-9-5 and the second pressure tongue 2-9-8 are connected by a second pin 2-9-7. The second spacer 2-9-3 and the second pressure tongue 2-9-8 are positioned between... The second spring 2-9-4 is installed, and the second spacer 2-9-3 abuts against the connecting shaft on the side opposite to the second spring 2-9-4. The end of the connecting shaft opposite to the second screw 2-9-5 passes through the second support 2-9-2, and the end of the connecting shaft passing through the second support 2-9-2 is connected to the hinge clamp 2-9-1. The hinge clamp 2-9-1 is also hinged to a handle for controlling the linear movement of the connecting shaft in the second spacer 2-9-3. The bottom of the second pressure tongue 2-9-8 is provided with an inclined surface, which faces the fine adjustment device 2-10.

[0047] Furthermore, a second composite bushing 2-9-6 is installed between the second screw 2-9-5 and the second pressure tongue 2-9-8.

[0048] In this embodiment, the hinge clamp 2-9-1, the second spacer 2-9-3, and the second screw 2-9-5 are first assembled together. Then, this component is assembled with the second support 2-9-2. Finally, the second spring 2-9-4, the second composite bushing 2-9-6, and the second pressure tongue 2-9-8 are installed, and the second pin 2-9-7 is hammered in for fixation. In this device, the hinge clamp 2-9-1 acts as a clamping / releasing mechanism. Under the action of the second spring 2-9-4, continuous pressure is applied to the inclined surface of the second pressure tongue 2-9-8, thereby limiting the position of the roller shaft 1-1. The main functions of the second composite bushing 2-9-6 include reducing friction, reducing wear, improving mechanical properties, and extending service life.

[0049] Example 5

[0050] like Figure 12-14 As shown, based on embodiment 3, the fine-tuning device 2-10 includes a knob 2-10-1 and a third support 2-10-3 that are nested together. A third screw 2-10-2 is inserted through the third support 2-10-3. One end of the third screw 2-10-2 extends into the knob 2-10-1. A screw is inserted through the top of the knob 2-10-1. The screw is threadedly connected to the third screw 2-10-2. A pin is inserted through the side wall of the knob 2-10-1 to make the third screw 2-10-2 and the knob 2-10-1 rotate synchronously.

[0051] The third screw 2-10-2 is threaded to the end opposite to the knob 2-10-1 with a third pressure tongue 2-10-5. The upper slide rail 2-8 has a through groove on its side wall, and a pin is provided in the groove to restrict the rotational movement of the third support 2-10-3 and the third pressure tongue 2-10-5. The bottom of the third pressure tongue 2-10-5 is provided with an inclined surface, which faces the quick clamping device 2-9.

[0052] Furthermore, a third composite bushing 2-10-6 in an inverted T shape is installed between the third screw 2-10-2 and the third support 2-10-3. The third screw 2-10-2 is circumferentially sleeved with a third spacer 2-10-4. The bottom of the third composite bushing 2-10-6 is connected to the top of the third spacer 2-10-4.

[0053] Furthermore, the third support 2-10-3 has two blind holes along a direction parallel to the axis, and a third spring 2-10-7 is installed in the blind holes. A steel ball 2-10-8 is installed on the top of the third spring 2-10-7. The bottom of the knob 2-10-1 has several spherical holes that mate with the steel ball 2-10-8.

[0054] In this embodiment, after the fine-tuning device 2-10 is assembled on the upper slide rail 2-8, two pin holes need to be made on the side of the upper slide rail 2-8 and pins need to be hammered in for anti-rotation and fixation of the fine-tuning device 2-10; in addition, a pin needs to be hammered into the end face of the upper slide rail 2-8 for anti-rotation of the third pressure tongue 2-10-5. First, assemble the third screw 2-10-2, the third support 2-10-3, the third spacer 2-10-4, and the third composite bushing 2-10-6 together, then install the third spring 2-10-7 and the steel ball 2-10-8, install the knob 2-10-1 and tighten it with screws, and finally screw the third pressure tongue 2-10-5 into the third screw 2-10-2 to complete the assembly. After assembly, the gap between knob 2-10-1 and the third support 2-10-3 is smaller than the diameter of steel ball 2-10-8, and knob 2-10-1 is provided with evenly distributed grooves (spherical holes) to ensure segmented turning, thereby achieving fine-tuning control. In this device, each turn of knob 2-10-1 adjusts the height of the inclined surface of the third pressure tongue 2-10-5 by one pitch, which is equivalent to the lowering / raising screw 2-10-2, thus providing fine-tuning for the front and rear positions of roller shaft 1-1. The main functions of the third composite bushing 2-10-6 and the third spacer 2-10-4 include reducing friction, reducing wear, improving mechanical properties, and extending service life.

[0055] Example 6

[0056] Based on Example 1, the scraper blades 1-12 have a horizontal angle of 96°.

[0057] The scraper blades are designed with an angle of 96° from 1 to 12, which effectively solves the problem of glue splattering.
