Description

Technical Field

[0001] This application belongs to the field of coating machine roller water replenishment and glue scraping equipment, specifically relating to a coating machine roller water replenishment and glue scraping device based on infrared control. Background Technology

[0002] Modern coating machines have a water replenishment device and a scraper device. The water replenishment device is used to lubricate the rollers that are not coated with paper, preventing damage to the roller surface caused by the scraper. The water replenishment device is manually controlled and adjusted. During normal production, manual control can only fix one angle. If the paper web shifts, or if the conveyor changes causing the paper to move left or right, or if the paper width changes, and the adjustment is not timely, the sprayed water will spray onto the paper, or some rollers will not be sprayed with water. The former will cause the paper to become wet again, leading to edge curling or other quality problems, while the latter will cause the rollers to dry and rub, accelerating the damage to the rollers.

[0003] The scraper device is placed close to the coating roller to scrape off the latex from areas on the roller where no paper is being coated, preventing glue from splashing off. The scraper device is manually controlled, and during normal production, it can only be fixed at one angle. If the paper web shifts, or if the conveyor changes causing the paper to move left or right, or if the paper width changes, and adjustments are not made in time, the glue will not be applied to the paper, or glue will splash off. Utility Model Content

[0004] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a coating machine roller water replenishment and scraping device based on infrared control. This application uses infrared sensing of the width of the paper to automatically adjust the position of the water replenishment device and the scraping device to match the position of the paper on the roller, thereby optimizing the use effect.

[0005] The technical solution adopted by this application to solve its existing problems is:

[0006] A coating machine roller water replenishment and scraping device based on infrared control is disclosed. The feed end of the roller is equipped with a paper width sensor. At both ends below the roller, scrapers that abut against the circumferential surface of the roller are provided. The scrapers are connected to a first telescopic mechanism. At the top of both ends of the roller, nozzles that are connected to water pipes are provided. The nozzles are connected to a second telescopic mechanism.

[0007] Preferably, the paper width sensor is an infrared grating, and the length of the infrared grating is greater than or equal to the length of the rubber roller.

[0008] Preferably, the two ends of the rubber roller are rotatably connected to brackets, and the two brackets are fixedly connected by a fixing plate.

[0009] Preferably, the fixing plate is disposed at one end of the bracket located at the feed end of the rubber roller, and the infrared grating is fixedly connected to the fixing plate.

[0010] Preferably, the first telescopic mechanism and the second telescopic mechanism are fixed to the end face of the fixed plate away from the rubber roller, the end of the first telescopic rod of the first telescopic mechanism is fixedly connected to the scraper, and the end of the second telescopic rod of the second telescopic mechanism is connected to the nozzle.

[0011] Preferably, the nozzle is fixedly mounted on the nozzle frame, and the nozzle frame is provided with a through hole, which is fitted onto the second telescopic rod.

[0012] Preferably, the nozzle frame is threaded with a fastening bolt, the end of which passes through the through hole and abuts against the circumferential surface of the second telescopic rod.

[0013] Preferably, a sleeve is fitted onto the second telescopic rod, and the sleeve is fixedly connected to the bracket.

[0014] Preferably, the first telescopic mechanism and the second telescopic mechanism are electric cylinders, pneumatic cylinders or hydraulic cylinders.

[0015] Preferably, the first telescopic mechanism and the second telescopic mechanism are electric cylinders, and the first telescopic mechanism, the second telescopic mechanism, and the paper width sensor are all electrically connected to the electronic control system of the coating machine.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] (1) By sensing the width of the paper with infrared, the position of the water replenishment device and the glue scraping device are automatically adjusted to match the position of the paper on the glue roller, thereby optimizing the use effect and effectively avoiding the phenomenon that the spray water is sprayed onto the paper, resulting in the paper not being able to be coated with glue or the glue being splattered.

[0018] (2) The glue scraping device and the water replenishment device are independent units, which makes it easy to modify the existing coating machine and also easy to repair and replace after damage. Attached Figure Description

Detailed Implementation

[0026] The attached figure shows a preferred embodiment of the infrared-controlled coating machine roller water replenishment and glue scraping device. The following is a more detailed description of this application in conjunction with the attached figure.

[0027] An infrared-controlled coating machine roller water replenishment and glue scraping device, consisting of... Figures 1 to 3 As shown, the feed end of the rubber roller 1 is equipped with a paper width sensor for detecting the width and position of the paper. To ensure more accurate detection of the paper width and running posture, the paper width sensor uses an infrared grating 4, the length of which is greater than or equal to the length of the rubber roller 1. The infrared grating 4 comprises two unit components: an emitting unit and a receiving unit. These two unit components are respectively located on the upper and lower sides of the rubber roller 1, ensuring that the paper passes between them.

[0028] Meanwhile, the infrared grating 4 and the rubber roller 1 are spaced a certain distance apart to allow time for the operation of the scraping device and the water replenishment device.

[0029] The rubber roller 1 has scrapers 5 at both ends below that abut against the circumferential surface of the rubber roller 1. The scrapers 5 are connected to the first telescopic mechanism 7. The rubber roller 1 has nozzles 8 at both ends above that are connected to the water pipe 9. The nozzles 8 are connected to the second telescopic mechanism 13.

[0030] The end of the first telescopic rod 6 of the first telescopic mechanism 7 is fixedly connected to the scraper 5, and the end of the second telescopic rod 11 of the second telescopic mechanism 13 is connected to the nozzle 8.

[0031] The rubber roller 1 is rotatably connected to two brackets 2 at both ends, and the two brackets 2 are fixedly connected by a fixing plate 3.

[0032] The fixing plate 3 is disposed on the support 2 at the feeding end of the rubber roller 1, and the infrared grating 4 is fixedly connected to the fixing plate 3.

[0033] The first telescopic mechanism 7 and the second telescopic mechanism 13 are fixed to the end face of the fixed plate 3 away from the rubber roller 1.

[0034] The nozzle 8 is fixedly mounted on the nozzle frame 10, and the nozzle frame 10 is provided with a through hole, which is fitted onto the second telescopic rod 11.

[0035] The nozzle holder 10 is threaded with a fastening bolt 1001, the end of which passes through a through hole and abuts against the circumferential surface of the second telescopic rod 11. This arrangement allows for adjustment of the position of the nozzle 8 by rotating the nozzle holder 10, thereby changing the water supply direction and position.

[0036] During the spraying process, the nozzle 8 generates a reverse impact force, which causes the second telescopic rod 11 to sway. To prevent the second telescopic rod 11 from swaying, a sleeve 12 is fitted onto the second telescopic rod 11, and the sleeve 12 is fixedly connected to the bracket 2. The sleeve 12 is detachably connected to the bracket 2 by bolts.

[0037] The first telescopic mechanism 7 and the second telescopic mechanism 13 are equipped with electric cylinders, pneumatic cylinders or hydraulic cylinders.

[0038] In this embodiment, for ease of control and rapid action, the first telescopic mechanism 7 and the second telescopic mechanism 13 are electric cylinders, and the first telescopic mechanism 7, the second telescopic mechanism 13 and the paper width sensor are all electrically connected to the electronic control system of the coating machine.

[0039] In this embodiment, the scraper 5, the first telescopic rod 6, and the first telescopic mechanism 7 form a scraping device, and the nozzle 8, nozzle frame 10, second telescopic rod 11, sleeve 12, and second telescopic mechanism 13 form a water replenishment device. Both the scraping device and the water replenishment device are independent units, facilitating the modification of existing coating machines and enabling easy repair and replacement after damage.

[0040] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
