Description

Technical Field

[0001] This utility model relates to the technical field of adhesive application devices, and more specifically, to an adhesive application system for the production of concrete water-saving and moisture-retaining curing films. Background Technology

[0002] In the production process of concrete water-saving and moisture-retaining curing membrane, superabsorbent polymer is fixed onto the plastic film with a water-soluble adhesive, which is called membrane adhesive; while the adhesive used to connect the two membranes during construction and paving operations is called overlap adhesive.

[0003] In the overlapping and adhesive application stage of the curing membrane production line, two workers typically monitor the process from opposite sides, manually adjusting the amount and position of adhesive application and moving back and forth with the production line. However, at high speeds, manual operation becomes difficult to synchronize, and problems are often too late to correct when they are discovered. Furthermore, the curing membrane's trajectory is generally a horizontal curve as it is conveyed by the conveyor rollers, making it prone to missed areas and uneven application. These un-adhesive sections are vulnerable to strong winds during field construction, causing the membrane to be easily blown away. Even pressing it with sandbags and gravel cannot completely solve the problem, affecting the concrete curing effect. Utility Model Content

[0004] The purpose of this invention is to provide a coating system for the production of water-saving and moisture-retaining curing films for concrete, which solves the problems of missed coating and uneven coating during the coating process.

[0005] This utility model is achieved through the following technical solution: a glue application system for producing concrete water-saving and moisture-retaining curing film, including a frame and a platform, on which a curing film is conveyed, and glue application pipes are respectively set above the two sides of the front end of the curing film. The platform is connected to the frame through a translation mechanism, which is used to drive the platform to move horizontally perpendicular to the conveying direction of the curing film. A scraper is provided on the frame to contact the upper surface of the curing film.

[0006] Furthermore, the platform is equipped with an offset sensor for detecting the movement trajectory of the health care membrane, and the offset sensor is connected to the translation mechanism via a signal.

[0007] Furthermore, the offset sensor is an infrared sensor or a diffuse reflective photoelectric switch.

[0008] Furthermore, a uniform roller that contacts the upper surface of the curing film is rotatably connected to the frame.

[0009] Furthermore, the glue-spreading roller is arranged behind the scraper plate along the conveying direction of the curing film.

[0010] Furthermore, the platform is equipped with a glue-spreading groove that works in conjunction with the glue-spreading roller.

[0011] Furthermore, the platform is equipped with a collection trough that works in conjunction with the scraper.

[0012] Furthermore, the adhesive application tube is connected to at least two adhesive outlets perpendicular to the direction of the curing membrane.

[0013] This utility model has at least the following advantages and beneficial effects: by setting up a translation mechanism, the platform can move horizontally and perpendicular to the direction of the curing film transmission, and the positional deviation of the curing film can be adjusted in real time to ensure that the adhesive application area is always aligned with the edge of the curing film, thus avoiding glue overflow or missed application.

[0019] Example

[0020] like Figures 1 to 3As shown, this embodiment mainly discloses a glue application system for producing concrete water-saving and moisture-retaining curing membrane 2, including a frame and a platform 1. The curing membrane 2 is conveyed through the platform 1. Glue application pipes 3 are respectively installed above the two sides of the conveying front end of the curing membrane 2. The platform 1 is connected to the frame through a translation mechanism 4, which drives the platform 1 to move horizontally perpendicular to the conveying direction of the curing membrane 2. A scraper 5 is provided on the frame to contact the upper surface of the curing membrane 2. Specifically, the frame is fixed on a stable plane to provide stable support. The platform 1 is made of stainless steel. The curing membrane 2 is adhered to the upper surface of the platform 1. The conveying rollers on the frame flatten the curing membrane 2 and allow it to pass over the platform 1. Glue application pipes 3 are respectively installed on both sides of the front end to add overlapping glue to the curing membrane 2. This improves the troublesome situation of having to adjust the addition position according to the left and right swing of the membrane when adding glue through a single-sided glue application pipe 3, ensuring that glue is applied to the overlapping areas of the curing membrane 2 on both sides. The translation mechanism 4 allows platform 1 to move horizontally and perpendicularly to the transmission direction of the curing film 2, enabling real-time adjustment of the positional deviation of the curing film 2. This ensures the adhesive application area is always aligned with the edge of the curing film 2, preventing adhesive overflow or missed application. The translation mechanism 4 can be a screw drive mechanism, where a motor drives the screw to rotate, causing the screw to be threadedly connected to platform 1. Alternatively, the translation mechanism 4 can be a linear actuator drive, where the linear actuators on both sides of platform 1 extend and retract linearly to move platform 1. The squeegee 5 contacts the upper surface of the curing film 2, effectively controlling the thickness and uniformity of the adhesive, thus improving the quality of the curing film 2.

[0021] Furthermore, in a specific implementation, the platform 1 provided in this embodiment of the present invention is equipped with an offset sensor 6 for detecting the movement trajectory of the health-preserving membrane 2. The offset sensor 6 is signal-connected to the translation mechanism 4. Specifically, the offset sensor 6 is embedded in the platform 1, with its detection end flush with the upper surface of the platform 1, enabling non-contact detection and avoiding scratching the health-preserving membrane 2. The offset sensors 6 are symmetrically arranged on both sides of the transmission path of the platform 1 (corresponding to the standard position boundary of the health-preserving membrane 2) to monitor in real time whether the membrane material deviates from the preset trajectory. Under normal conditions, the edge of the health-preserving membrane 2 is within the detection range of the offset sensor 6, and the offset sensor 6 outputs a "no offset" signal; when the membrane material shifts to the left / right, one side of the offset sensor 6 detects that the edge of the membrane material exceeds the threshold range, triggering an "offset" signal. The offset sensor 6 transmits the deviation signal to the processor to control the translation mechanism 4 to drive the platform 1 to dynamically correct the deviation, ensuring that the health-preserving membrane 2 does not shift during transmission. The offset sensor 6 is signal-connected to the translation mechanism 4, enabling real-time adjustment of the position of the platform 1 to ensure the accuracy of adhesive application.

[0022] Preferably, the offset sensor 6 is an infrared sensor or a diffuse reflection photoelectric switch. When the health-preserving membrane 2 is not offset, the intensity of the reflected light from the receiver is recorded as a reference value. If the health-preserving membrane 2 shifts to the left, the intensity of the reflected light received by the sensor on the left side increases (the edge of the membrane enters the detection area), while the intensity of the reflected light on the right side decreases. The opposite is true if the health-preserving membrane 2 shifts to the right. By comparing the changes in the intensity of the reflected light from the sensors on both sides, the direction and magnitude of the offset are determined.

[0023] Furthermore, in a specific implementation, a glue-spreading roller 7, which contacts the upper surface of the curing film 2, is rotatably connected to the frame provided in this embodiment of the present invention. Specifically, the glue-spreading roller 7 is in the shape of a drum, which further evenly distributes the glue, eliminates the uneven glue distribution that may occur during the glue application process, and improves the surface quality of the curing film 2.

[0024] Preferably, the spreading roller 7 is arranged behind the scraper 5 along the conveying direction of the curing film 2. After the scraper 5 initially smooths the adhesive, the spreading roller 7 further presses the adhesive layer by rotating, eliminating any tiny air bubbles or streaks that may remain after scraping, ensuring a smooth and uniform adhesive surface. This allows for further uniform distribution of the adhesive after the scraper 5 has initially controlled the adhesive thickness, ensuring a smooth surface of the curing film 2 free of air bubbles and adhesive buildup.

[0025] Preferably, the platform 1 is provided with a glue-spreading groove 11 that cooperates with the glue-spreading roller 7. Specifically, the glue-spreading groove 11 is an arc groove concentric with the glue-spreading roller 7, which can increase the contact area between the glue-spreading roller 7 and the curing film 2, so that the overlapping glue applied on the curing film 2 is more uniform.

[0026] Furthermore, in a specific implementation, the platform 1 provided in this embodiment of the present invention is provided with a collection groove 12 that cooperates with the scraper 5. Specifically, the scraper 5 is inserted into the collection groove 12, such that the lower edge of the scraper 5 is lower than the upper surface of the platform 1, which can fully press down the curing film 2 to scrape off the glue, leaving the excess overlapping glue on the side in the direction of film arrival for reuse, preventing waste and maintaining a clean production environment.

[0027] Furthermore, in specific implementations, the adhesive application tube 3 provided in this embodiment of the invention has at least two adhesive outlets 31 connected to it in the direction perpendicular to the conveying direction of the curing membrane 2. This enables multi-point adhesive application, ensuring that the adhesive is evenly distributed on the curing membrane 2, avoiding excessive or insufficient adhesive in certain areas, and improving the quality and consistency of the curing membrane 2. Specifically, a solenoid valve 32 is connected to the adhesive application tube 3, which can adjust the amount of adhesive applied and the application time.
