An adjustable spacing applicator wear resistant metering bar device

Abstract

This utility model belongs to the technical field of glue applicator, specifically relating to a glue applicator anti-wear metering rod device with adjustable spacing. It includes a clamp for fixing the metering rod, the clamp being fixedly connected to a connecting plate. The connecting plate is equipped with an air jet assembly, a positioning mechanism, and an adjustment assembly. This adjustable-spacing glue applicator anti-wear metering rod device achieves precise control of the spacing between the metering rod and the glue roller through the adjustment assembly and the positioning mechanism. When the screw is rotated, the threaded sleeve drives the mounting plate to move along the guide rod, and the connecting plate moves accordingly, adjusting the clamp and metering rod to the target spacing. Furthermore, under the action of the positioning rod, after the positioning rod abuts against the glue roller, there is a slight distance between the metering rod and the glue roller. This process eliminates the need for repeated adjustments, ensuring a uniform and stable spacing, reducing friction and wear caused by spacing deviations, and preventing the metering rod from shaking and increasing wear, thus extending its service life.

Description

Technical Field

[0001] This utility model relates to the field of glue applicator technology, specifically to a glue applicator anti-wear metering rod device with adjustable spacing. Background Technology

[0002] In the sizing process of industries such as papermaking and printing, the metering rod is the core component for controlling the amount of adhesive applied. The distance between the metering rod and the sizing roller directly determines the thickness and uniformity of the adhesive layer.

[0003] Currently, when using metering rods, they need to be in long-term contact with the application rollers and maintain a small gap. During operation, impurities or fibers in the adhesive can easily cause friction and wear between the two, resulting in scratches and dents on the surface of the metering rods, which in turn destroys the spacing stability and aggravates uneven coating. At the same time, worn metering rods need to be replaced frequently, increasing equipment downtime and production costs. In view of this, a wear-resistant metering rod device for application machines with adjustable spacing is proposed. Utility Model Content

The positioning mechanism includes: A positioning rod is slidably connected to a fixing sleeve, which is fixedly connected to the outer wall of the connecting plate. A circular ring is fixed to a positioning rod, and the circular ring is elastically connected to a fixed sleeve by a return spring. A rotating block is rotatably connected to the side of the circular ring away from the positioning rod. and a limiting component, wherein the limiting component is disposed on the connecting plate.

[0006] Preferably, the limiting component includes a limiting block, the outer wall of the limiting block is provided with a slot and a sliding groove, the sliding groove slides with a guide block, a connecting block is fixedly connected to the outer wall of the limiting block, and a screw is threadedly connected to the connecting block.

[0007] Preferably, the guide block is fixedly connected to the outer wall of the connecting plate, and the screw is rotatably connected to the outer wall of the connecting plate.

[0008] Preferably, the rotating block matches the slot, and the rotating block can be rotatably inserted into the slot.

[0009] Preferably, the jet assembly includes a jet chamber, the jet chamber is provided with an air source connection port, and the jet chamber has a jet outlet on its lower side.

[0010] Preferably, the adjustment assembly includes a mounting plate, a threaded sleeve is fixedly connected to the mounting plate, a screw is threadedly connected to the threaded sleeve, a guide sleeve is fixedly connected to the mounting plate, and a guide rod is slidably connected in the guide sleeve.

[0011] Preferably, the screw is rotatably connected to the connecting plate, and the guide rod is fixedly connected to the connecting plate.

[0012] This invention provides a wear-resistant metering rod device for a glue applicator with adjustable spacing. It offers the following advantages: (1) The adjustable spacing anti-wear metering rod device of the glue applicator achieves precise control of the distance between the metering rod and the glue applicator roller through the action of the adjustment component and the positioning mechanism. When the screw is rotated, the threaded sleeve drives the mounting plate to move along the guide rod, and the connecting plate moves in conjunction with it, driving the clamp and metering rod to adjust to the target distance. Furthermore, under the action of the positioning rod, after the positioning rod comes into contact with the glue roller, there is a small distance between the metering rod and the glue roller. This process does not require repeated trial and adjustment, ensuring that the distance is uniform and stable, reducing friction and wear caused by distance deviation, and avoiding the metering rod shaking, which aggravates wear and extends service life.

[0013] (2) The adjustable spacing anti-wear metering rod device of the glue applicator can adjust the position of the limiting block by using the limiting component, so that the position of the positioning rod can be adjusted after the rotating block is inserted into the slot, so that the distance between the metering rod and the glue roller can be adjusted after the positioning rod abuts against the glue roller, which makes it easy to readjust the distance between the metering rod and the glue roller after the metering rod wears out, and ensures that the distance between the metering rod and the glue roller is stable.

[0014] (3) The adjustable spacing anti-wear metering rod device of the glue applicator uses the jet assembly to continuously spray air through the jet nozzle to form an air curtain between the metering rod and the glue applicator roller, which prevents impurities and fibers in the glue from entering the gap between them, thereby reducing abrasive wear from the source. The air curtain also plays a lubricating role, reducing the friction coefficient of the contact surface, further reducing the generation of scratches and dents on the surface of the metering rod, and ensuring coating uniformity.

[0019] 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.

[0020] Please see Figures 1-5 This utility model proposes a wear-resistant metering rod device for a glue applicator with adjustable spacing, including a clamp 2 for fixing the metering rod 1, the clamp 2 being fixedly connected to a connecting plate 3, an air jet assembly 4 being provided on the connecting plate 3, and a positioning mechanism 5 and an adjustment assembly 6 being provided on the connecting plate 3.

[0021] In an embodiment of this utility model, in order to adjust the distance between the metering rod 1 and the glue roller, the adjustment component 6 specifically includes a mounting plate 61, a threaded sleeve 62 fixedly connected to the mounting plate 61, a screw 63 threadedly connected to the threaded sleeve 62, a guide sleeve 64 fixedly connected to the mounting plate 61, a guide rod 65 slidably connected in the guide sleeve 64, the screw 63 rotatably connected to the connecting plate 3, and the guide rod 65 fixedly connected to the connecting plate 3. When adjusting the distance between the metering rod 1 and the glue application surface, the handle of the screw 63 is rotated. Under the guidance of the guide rod 65 and the guide sleeve 64, the connecting plate 3 is moved, thereby causing the connecting plate 3 to drive the metering rod 1 to move synchronously until the preset distance is reached.

[0022] Furthermore, in order to achieve distance positioning between the metering rod 1 and the rubber roller during the adjustment process, the positioning mechanism 5 specifically includes a positioning rod 51, a ring 53, and a limiting component 55. The positioning rod 51 is slidably connected to the fixed sleeve 52, which is fixedly connected to the outer wall of the connecting plate 3. The ring 53 is fixed to the positioning rod 51, and the ring 53 and the fixed sleeve 52 are elastically connected by a return spring. A rotating block 54 is rotatably connected to the side of the ring 53 away from the positioning rod 51. The limiting component 55 is disposed on the connecting plate 3 and includes a limiting block 551. The outer wall of 551 is provided with a slot 552 and a slide groove 553. The rotating block 54 matches the slot 552 and can be rotatably inserted into the slot 552. By rotating the rotating block 54, the positioning rod 51 can be fixed after the rotating block 54 is inserted into the slot 552. Then, during the process of adjusting the distance between the measuring rod 1 and the rubber roller, after the positioning rod 51 abuts against the rubber roller, the measuring rod 1 is adjusted to the preset distance without repeated trial and adjustment, ensuring that the distance is uniform and stable, reducing friction and wear caused by distance deviation, and avoiding the measuring rod 1 shaking and aggravating wear, thus extending its service life.

[0023] Furthermore, the slide 553 slides with the guide block 554, and a connecting block 555 is fixedly connected to the outer wall of the limiting block 551. The connecting block 555 is threadedly connected to a screw 556. The guide block 554 is fixedly connected to the outer wall of the connecting plate 3, and the screw 556 is rotatably connected to the outer wall of the connecting plate 3. By rotating the screw 556, the position of the limiting block 551 can be adjusted under the guidance of the guide block 554. After the rotating block 54 is inserted into the slot 552, the position of the positioning rod 51 can be adjusted. After the positioning rod 51 abuts against the rubber roller, the distance between the metering rod 1 and the rubber roller can be adjusted, which makes it easy to readjust the distance between the metering rod 1 and the rubber roller after the metering rod 1 wears out, and ensures that the distance between the metering rod 1 and the rubber roller is stable.

[0024] Furthermore, in order to reduce the wear of the metering rod 1, the jet assembly 4 specifically includes a spray chamber 41, an air source connection port 43 on the spray chamber 41, and a jet nozzle 42 on the lower side of the spray chamber 41. Compressed air is introduced into the spray chamber 41 through the air source connection port 43. After being buffered by the spray chamber 41, the compressed air is evenly sprayed out from the jet nozzle 42 to clean the surface of the metering rod 1 and the surrounding area, removing dust, glue residue and other impurities. During the glue application process, jetting can be performed continuously or intermittently as needed to form an air curtain between the metering rod 1 and the glue application roller, preventing impurities and fibers in the glue from entering the gap between them, reducing abrasive wear from the source. The air curtain also acts as a lubricant, reducing the coefficient of friction of the contact surface, further reducing the generation of scratches and dents on the surface of the metering rod 1, and ensuring coating uniformity.

[0025] It should be noted that all the electrical components mentioned above are existing technology products. Those skilled in the art should select, install, and debug the circuits according to their needs to ensure that all electrical appliances function properly. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be obtained by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are imposed here. In use, first rotate the rotating block 54 so that it can fix the positioning rod 51 after being inserted into the slot 552. Then rotate the handle of the screw 63. Under the guidance of the guide rod 65 and the guide sleeve 64, the connecting plate 3 moves, which in turn drives the measuring rod 1 to move synchronously. After the positioning rod 51 abuts against the rubber roller, the measuring rod 1 is adjusted to the preset spacing without repeated trial adjustments, ensuring uniform and stable spacing and reducing friction and wear caused by spacing deviation. At the same time, by rotating the screw 556, the guide block 554... Under the guiding action, the position of the limiting block 551 is adjustable. After the rotating block 54 is inserted into the slot 552, the position of the positioning rod 51 is adjustable. After the positioning rod 51 abuts against the rubber roller, the distance between the metering rod 1 and the rubber roller is adjustable. This makes it easy to readjust the distance between the metering rod 1 and the rubber roller after the metering rod 1 wears out. Compressed air is introduced into the spray chamber 41 through the air source connection port 43. After being buffered by the spray chamber 41, the compressed air is evenly sprayed out from the air jet port 42 to blow clean the surface of the metering rod 1 and the surrounding area, removing dust, glue residue and other impurities.
