Description

Technical Field

[0001] This utility model belongs to the field of coating equipment technology, and more specifically, it relates to a device for uniformly coating adhesive rollers. Background Technology

[0002] In the latex filament processing, the use of adhesive is a key step in improving product performance and optimizing production processes. The workflow of the adhesive uniform coating roller in latex filament processing is as follows: the adhesive supply system delivers the adhesive to the surface of the coating roller through a metering pump and distributor to form a uniform liquid film. At the same time, the latex filament enters the coating area with a constant tension. The coating roller rotates to transfer the adhesive onto the latex filament. The doctor blade scrapes off the excess adhesive to control the thickness. During this process, the tension control system maintains the tension of the latex filament to be stable, and the thickness detection device monitors and feeds back the data in real time for control.

[0003] The existing application number is CN202321831959.0. This utility model relates to the field of coating roller technology and discloses a coating roller, including a roller core, connecting seats symmetrically arranged on the surface of the roller core, adhesive layers laminated on the surface of the connecting seats, and a mounting seat on the top of the roller core. This utility model designs the original one-piece roller structure into two semi-circular adhesive layer structures. With the use of connecting seats, the two adhesive layer structures can cover the surface of the roller core. When replacement is needed, only the connecting seats need to be removed, without replacing the roller core, reducing costs and facilitating the installation of new rollers. The mounting seat has a water storage tank, which, together with the drip nozzle, allows water to drip onto the adhesive layer. With the use of a cleaning felt, water stains along with the adhesive can be cleaned away, preventing the roller from yellowing and forming a crust after long-term use, thus ensuring the quality of subsequent production.

[0004] Based on the above, the coating rollers of traditional coating equipment are mostly integral structures. For substrates of different materials and widths, the required adhesive thickness varies, often requiring the replacement of coating rollers of different specifications (such as smooth coating rollers and grooved coating rollers). This results in high equipment adjustment costs and low efficiency. Utility Model Content

For substrates of different materials and widths, the required adhesive thickness of the substrate is different, and it is often necessary to replace coating rollers of different specifications (such as smooth coating rollers and grooved coating rollers), resulting in high equipment adjustment costs and low efficiency.

The rotary joint is rotatably connected to the outer side of the left-hand clamping and fixing component and is externally connected to a vacuum pump. The uniform coating mechanism is positioned above the coating mounting frame. The coating adjustment mechanism is positioned inside the clamping and fixing components.

[0009] Furthermore, the coating adjustment mechanism also includes: an adjusting fixed slide, an adjusting drive slider, and an adjusting drive screw; the adjusting fixed slide is fixedly connected to the inner side of two sets of clamping and fixing members; multiple sets of adjusting drive sliders are provided, with the middle set of adjusting drive sliders fixedly connected to the front of the adjusting fixed slide, and the other sets of adjusting drive sliders slidably connected to the front of the adjusting fixed slide; the adjusting drive screw is threadedly connected to the inner side of the right set of clamping and fixing members, and the left end of the adjusting drive screw is rotatably connected to the rightmost set of adjusting drive sliders.

[0010] Furthermore, the coating adjustment mechanism also includes: an adjustment support roller and an adjustment drive linkage; the adjustment support roller is provided in multiple sets, and the multiple sets of adjustment support rollers are respectively fixedly connected to the outer periphery of the adjustment drive slider. The multiple sets of adjustment support rollers are all cylindrical structures, and the coating outer wrapping material covers the outer side of the multiple sets of adjustment support rollers; the adjustment drive linkage is provided in multiple sets, and the multiple sets of adjustment drive linkages are hinged to each other.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the setting of a uniform coating mechanism, enables the uniformity detection component to monitor the levelness of the coating mounting frame. Once the coating mounting frame tilts during use, and the tilt angle exceeds the threshold of the uniformity detection component, the uniformity detection component controls the monitoring and warning component to open, emitting an audible and visual alarm to remind the worker to adjust the coating mounting frame in time, ensuring the level setting of the coating outer wrapping and guaranteeing the uniform distribution of the adhesive.

[0013] This invention utilizes a coating adjustment mechanism. A rotary joint, connected to an external vacuum pump, evacuates the inner side of the coating outer wrapper, tightly securing it to the outer circumference of the adjusting support rollers. These rollers provide support for the coating outer wrapper. When applying adhesive to different substrates, rotating the adjusting drive screw moves the rightmost set of adjusting drive sliders. Under the action of the adjusting drive linkage, these sliders move multiple sets of adjusting drive sliders at equal intervals, thus adjusting the spacing between the adjusting support rollers. This creates gaps between the rollers, causing the coating outer wrapper to indent inwards at these gaps due to the suction of the external vacuum pump. This allows for precise modification of the coating outer wrapper's surface morphology and flexible control of the adhesive flow, replacing the cumbersome method of replacing parts to adapt to different substrates. This reduces equipment adjustment costs and time, fundamentally improving the technical adaptability to diverse production needs and lowering production costs. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 2: This utility model provides a device for uniformly coating adhesive using a roller, which is based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a coating adjustment mechanism, which is located inside the clamping and fixing member 3.

[0025] The coating adjustment mechanism includes a coating baffle 201 and a masking adjustment screw 202. Two sets of coating baffles 201 are provided, and the two sets of coating baffles 201 are slidably connected to the inner side of the coating mounting frame 1.

Two sets of masking adjustment screws 202 are provided, and the two sets of masking adjustment screws 202 are threadedly connected to the upper left and right sides of the coating mounting frame 1, and the outer sides of the two sets of masking adjustment screws 202 are rotatably connected to the coating baffles 201.

[0026] The coating adjustment mechanism further includes: an adjustment fixed slide 203, an adjustment drive slider 204, and an adjustment drive screw 205; the adjustment fixed slide 203 is fixedly connected to the inner side of two sets of clamping and fixing parts 3; multiple sets of adjustment drive sliders 204 are provided, with the middle set of adjustment drive sliders 204 fixedly connected to the front of the adjustment fixed slide 203, and the other sets of adjustment drive sliders 204 slidably connected to the front of the adjustment fixed slide 203; the adjustment drive screw 205 is threadedly connected to the inner side of the right set of clamping and fixing parts 3, and the left end of the adjustment drive screw 205 is rotatably connected to the rightmost set of adjustment drive sliders 204.

[0027] The coating adjustment mechanism further includes: an adjustment support roller 206 and an adjustment drive linkage 207; multiple sets of adjustment support rollers 206 are provided, and the multiple sets of adjustment support rollers 206 are respectively fixedly connected to the outer periphery of the adjustment drive slider 204. The multiple sets of adjustment support rollers 206 are all cylindrical structures, and the coating outer wrapping part 4 covers the outer side of the multiple sets of adjustment support rollers 206; multiple sets of adjustment drive linkages 207 are provided, and the multiple sets of adjustment drive linkages 207 are hinged to each other. The multiple sets of adjustment drive linkages 207 together form a scissor structure, and the middle hinge points of the multiple sets of adjustment drive linkages 207 are respectively rotatably connected to the front end of the adjustment drive slider 204.

[0028] The coating adjustment mechanism also includes: a clamping screw 208 and a clamping contact 209; multiple sets of clamping screws 208 are provided, and the multiple sets of clamping screws 208 are threadedly connected to the outer periphery of the clamping fixing member 3; multiple sets of clamping contact 209 are provided, and the multiple sets of clamping contact 209 are all arc-shaped structures, and the multiple sets of clamping contact 209 are rotatably connected to the inner side of the clamping screw 208.

[0029] The specific usage and function of this embodiment: By rotating the shielding adjustment screw 202, the shielding adjustment screw 202 rotates, driving the coating baffle 201 to move. The movement of the coating baffle 201 enables applicability to substrates of different widths. The left and right ends of the coating outer wrapping 4 are respectively inserted into the inner side of the clamping and fixing member 3. The clamping screw 208 is rotated, driving the clamping contact member 209 to move inward. The inward movement of the clamping contact member 209 achieves clamping and fixing of the coating outer wrapping 4. When coating the latex filament, the coating outer wrapping 4 evenly distributes the adhesive onto the surface of the latex filament. The elastic material structure of the coating outer wrapping 4 makes the coating outer wrapping 4 fit more closely to the latex filament. At the same time, the rotary joint 5 uses an external vacuum pump to evacuate the air from the inside of the coating outer wrapping 4. Tightly wrapped around the outer periphery of the adjusting support roller 206, the adjusting support roller 206 supports the coating outer wrapping 4. When applying adhesive to different substrates, the adjusting drive screw 205 is rotated, which drives the rightmost set of adjusting drive sliders 204 to move. Under the action of the adjusting drive connecting rod 207, the adjusting drive sliders 204 move at equal intervals, thereby adjusting the spacing of the adjusting support rollers 206. This creates a certain gap between the sets of adjusting support rollers 206. At this time, the part of the coating outer wrapping 4 at the gap is concave inward due to the suction of the external vacuum pump, thereby changing the surface shape of the coating outer wrapping 4 and increasing the amount of adhesive passing through, thus achieving the adjustment of the amount of adhesive passing through.
