Description

Technical Field

[0001] This utility model relates to the field of anti-sticking technology for metering rods, specifically an anti-sticking component for grooved metering rods of a glue applicator. Background Technology

[0002] In industries such as papermaking and film coating, grooved metering rods are the core components of sizing machines for controlling the amount of adhesive applied. The spiral or straight grooves evenly distributed on their surface can achieve precise metering and uniform coating of adhesive through the action of storing and scraping adhesive.

[0003] Currently, groove metering rods are prone to "sticking" problems during use (i.e., the adhesive material dries and accumulates in the grooves). The specific reasons are as follows: the groove depth of traditional groove metering rods is relatively shallow, and the cross-section is mostly right angle or U-shaped. The adhesive material is easy to remain at the corners of the grooves, especially during the interval between machine stops. The residual adhesive material will quickly dry and form hard lumps. When the machine is restarted, it cannot be flushed by new adhesive material, resulting in groove blockage. In addition, due to the influence of paper dust, the recycled adhesive material contains impurities. When the impurities pass through the metering rod, they will cause wear on the metering rod, which will also lead to the "sticking" problem. In view of this, an anti-sticking component for groove metering rods of glue applicators is proposed. Utility Model Content

[0004] The main objective of this invention is to provide an anti-sticking component for the grooved metering rod of a glue applicator, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes an anti-sticking component for the grooved metering rod of a glue applicator, comprising a fixing base for fixing the metering rod, an mounting plate fixedly installed on the lower side of the fixing base, the metering rod being fixed to a rotating shaft, a scraper and a collection groove fixedly installed on the mounting plate, and a feeding and cleaning mechanism and an auxiliary cleaning component provided on the outer wall of the mounting plate, the feeding and cleaning mechanism comprising: The feeding chamber is fixedly installed on the lower side of the mounting plate, and a feeding trough is provided on the lower side of the feeding chamber; The filter is connected to the feeding trough via a connecting pipe, and the output port of the filter is connected to the feeding chamber. The filter is also connected to the collection trough via a connecting pipe. and a return pipe, the two ends of which are respectively connected to the feeding chamber and the feeding trough.

[0006] Preferably, a lubrication groove is formed in the inner wall of the fixing seat.

[0007] Preferably, the feeding chamber and the lubrication tank are connected by a first hose and a second hose.

[0008] Preferably, the material conveying of the first through pipe, the second through pipe, the first hose, the second hose, and the return pipe is all carried out by a pump body.

[0009] Preferably, the auxiliary cleaning component includes an air chamber, in which a piston is connected to a piston rod, and a connecting plate is fixedly connected to the end of the piston rod. A round rod is fixedly connected to the outer wall of the connecting plate, the round rod passes through a limiting sleeve and is slidably connected to the limiting sleeve, and a vertical plate is fixedly connected to the end of the round rod away from the connecting plate. A one-way inlet and a one-way outlet are provided on the outer wall of the air chamber.

[0010] Preferably, the air chamber is fixedly connected to the mounting plate, and the limiting sleeve is elastically connected to the connecting plate by a return spring.

[0011] Preferably, a cam is fixedly connected to the outer wall of the rotating shaft, the cam abuts against the vertical plate, and the rotating shaft is driven by a motor.

[0012] This utility model provides an anti-sticking component for the grooved metering rod of a glue applicator. It has the following beneficial effects: (1) The anti-clogging component of the groove metering rod of the glue applicator purifies the glue material through a filter via a feeding and cleaning mechanism. The recovered glue material enters the filter through the first pipe to remove impurities such as paper dust. The clean glue material is then conveyed to the metering rod through the feeding chamber to prevent impurities from wearing down the grooves or causing blockages. At the same time, the residual glue material collected in the collection tank flows back to the filter through the second pipe for further filtration. This, combined with the return pipe, enables the recycling of glue material and reduces waste. In addition, the glue material is conveyed to the lubrication groove of the fixed seat through a hose to form a lubricating film, reducing frictional loss when the metering rod rotates and reducing the probability of the metering rod clogging.

[0013] (2) When the grooved metering rod anti-sticking component of the glue applicator is driven by the motor to rotate the shaft, the cam periodically squeezes the vertical plate, drives the round rod and the connecting plate to move, and makes the piston rod reciprocate in the air chamber. Air is drawn in through the one-way inlet and high-pressure air is sprayed out through the one-way outlet, which accelerates the flow of the glue in the lubrication groove, makes the glue cover the surface of the metering rod more evenly, reduces the drying caused by glue retention, and further reduces the probability of the metering rod sticking.

[0018] 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.

[0019] Please see Figures 1-6 This utility model proposes an anti-sticking component for grooved metering rods of a glue applicator, including a fixing base 1 for fixing the metering rod 2, an mounting plate 3 fixedly installed on the lower side of the fixing base 1, the metering rod 2 being fixed to a rotating shaft 4, a scraper 6 and a collection trough 7 fixedly installed on the mounting plate 3, and a feeding and cleaning mechanism 8 and an auxiliary cleaning component 9 provided on the outer wall of the mounting plate 3. The rotating shaft 4 is driven by a motor. When the motor is started, it drives the rotating shaft 4, causing the metering rod 2 to rotate for glue application. During the glue application process, the scraper 6 continuously scrapes off excess glue from the surface of the metering rod 2, and the scraped glue falls into the collection trough 7. At the same time, the feeding and cleaning mechanism 8 is responsible for filtering and circulating the glue, and the auxiliary cleaning component 9 performs auxiliary cleaning simultaneously to prevent the rod from sticking.

[0020] In this embodiment of the utility model, in order to reduce the problem of sticking of the metering rod 2, the feeding and cleaning mechanism 8 specifically includes a feeding chamber 81, a filter 84, and a return pipe 88. The feeding chamber 81 is fixedly installed on the lower side of the mounting plate 3. A feeding trough 82 is provided on the lower side of the feeding chamber 81. The filter 84 is connected to the feeding trough 82 through a first connecting pipe 83. The output port of the filter 84 is connected to the feeding chamber 81. The filter 84 is connected to the collection tank 7 through a second connecting pipe 85. The two ends of the return pipe 88 are respectively connected to the feeding chamber 81 and the feeding trough 82. A lubrication groove 101 is provided in the inner wall of the fixed base 1. The feeding chamber 81 and the lubrication groove 101 are connected through a first flexible hose 86 and a second flexible hose 87. The first connecting pipe 83, the second connecting pipe 85, the first flexible hose 86, the second flexible hose 87, and the return pipe 88 are connected to each other. All materials are conveyed by a pump. During feeding, the rubber material in the feeding trough 82 is sent to the filter 84 through the first pipe 83 by the pump body. After filtering out impurities, it enters the feeding chamber 81 to provide clean rubber material for the metering rod 2. The rubber material recovered in the collection trough 7 is pumped into the filter 84 through the second pipe 85 for re-filtration and reuse. The excess rubber material in the feeding chamber 81 flows back to the feeding trough 82 through the return pipe 88 to form a cycle. At the same time, some rubber material enters the lubrication tank 101 through the first hose 86 and the second hose 87 to lubricate the contact part between the metering rod 2 and the fixed seat 1. This effectively removes impurities and dried particles from the rubber material, preventing impurities from clogging the grooves of the metering rod 2 or scratching the surface. This reduces the cause of rod clogging from the source. Rubber material lubrication reduces the rotational friction of the metering rod 2, reduces heat generation, prevents the rubber material from drying, and reduces the risk of rod clogging.

[0021] Furthermore, to further reduce the problem of sticking to the metering rod 2, specifically, the auxiliary cleaning component 9 includes an air chamber 91. A piston rod 92 is connected to the piston in the air chamber 91. A connecting plate 93 is fixedly connected to the end of the piston rod 92. A round rod 94 is fixedly connected to the outer wall of the connecting plate 93. The round rod 94 passes through a limiting sleeve 95 and is slidably connected to the limiting sleeve 95. A vertical plate 96 is fixedly connected to the end of the round rod 94 away from the connecting plate 93. A one-way inlet 97 and a one-way outlet 98 are provided on the outer wall of the air chamber 91. The air chamber 91 is fixedly connected to the mounting plate 3. The limiting sleeve 95 and the connecting plate 93 are elastically connected by a return spring. A convex... Wheel 5 and cam 5 abut against vertical plate 96. When shaft 4 rotates, it drives cam 5 to rotate synchronously. Cam 5 periodically squeezes vertical plate 96, pushing round rod 94 and connecting plate 93 to move, causing piston rod 92 to compress gas in air chamber 91. Gas is ejected through one-way outlet 98. When cam 5 rotates to a non-protruding part, return spring rebounds and drives connecting plate 93 to reset. Piston rod 92 moves back, and air chamber 91 draws in air through one-way inlet 97, completing the intake and exhaust cycle. The ejected high-pressure airflow accelerates the flow of rubber in lubrication groove 101, making the rubber more evenly cover the surface of metering rod 2, reducing drying caused by rubber retention, and further reducing the probability of metering rod 2 sticking.

[0022] 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 fix the measuring rod 2 with the fixing seat 1 to ensure a stable connection with the rotating shaft 4; start the motor to drive the rotating shaft 4, which will rotate the measuring rod 2 to perform the glue application operation. During the glue application process, the scraper 6 continuously scrapes off the excess glue on the surface of the measuring rod 2. The scraped glue falls into the collection tank 7. At the same time, during the feeding process, the glue in the feeding tank 82 is sent to the filter 84 through the first pipe 83 by the pump body. After filtering out impurities, it enters the feeding chamber 81 to provide clean glue for the measuring rod 2. The glue recovered in the collection tank 7 is pumped into the filter 84 through the second pipe 85 for re-filtration and reuse. The excess glue in the feeding chamber 81 flows back to the feeding tank 82 through the return pipe 88 to form a cycle. Meanwhile, some glue flows through the hose. 86 and 87 of the hose enter the lubrication tank 101 to lubricate the contact area between the metering rod 2 and the fixed seat 1. At the same time, when the rotating shaft 4 rotates, it drives the cam 5 to rotate synchronously. The cam 5 periodically squeezes the vertical plate 96, pushing the round rod 94 and the connecting plate 93 to move, so that the piston rod 92 compresses the gas in the air chamber 91. The gas is ejected through the one-way outlet 98. When the cam 5 rotates to the non-protruding part, the return spring rebounds and drives the connecting plate 93 to reset. The piston rod 92 moves back, and the air chamber 91 draws in air through the one-way inlet 97, completing the intake and exhaust cycle. The high-pressure airflow accelerates the flow of the rubber material in the lubrication tank 101, so that the rubber material covers the surface of the metering rod 2 more evenly and reduces the drying caused by the rubber material retention.
