Description

Technical Field

[0001] This invention belongs to the technical field of construction machinery and equipment for subway stations, and specifically relates to a device for applying adhesive to ALC partition walls. Background Technology

[0002] The adhesive properties of the ALC-specific bonding mortar are tailored to the core requirements of ALC isolation panel construction. It's not simply about high viscosity, but rather good thixotropy, sufficient initial tack, and high final bond strength, balancing smooth application with strong adhesion after bonding. After curing, it exhibits high bonding strength, tightly adhering to the ALC panel substrate. It will not detach or become hollow due to panel shrinkage or minor building settlement, and is well-suited to the porous and lightweight characteristics of ALC panels.

[0003] During the adhesive application process for ALC (Alternating Current Carbide) isolation panels, after the panels are fixed, the application process inevitably requires workers to operate at height, which is extremely time-consuming and labor-intensive, and carries a certain degree of danger. Defects in adhesive application machines include difficulties in delivering and applying high-viscosity adhesive, the influence of temperature and humidity changes on the rheological properties of the adhesive, easy clogging and stringing, high replacement costs for precision parts, and easy damage from direct contact with the adhesive. For ALC isolation panel installation, the adhesive used is a special ALC bonding mortar, characterized by strong initial tack and high final bond strength. However, due to the design of the adhesive directly contacting the extrusion mechanism, residual ALC bonding mortar can easily cause clogging and adhesion, leading to damage to parts. Therefore, it is necessary to research an adhesive application device that prevents non-contact adhesion between the adhesive and precision parts. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a roll-type non-contact anti-sticking adhesive coating device, which mainly solves the problems of high manufacturing cost, difficulty in conveying and coating high-viscosity adhesives, the influence of temperature and humidity changes on the rheological properties of adhesives leading to easy clogging and stringing, high replacement cost of precision parts, and easy damage to adhesives upon contact.

[0005] This invention is achieved through the following technical solution: A roll-type non-contact anti-adhesion adhesive application device consists of an adhesive application lifting platform, a base, a housing, a detachable scraper, front directional wheels, rear universal wheels, a pedal, a servo motor, a planetary reducer, a coupling, a bevel gear, a ball screw, a slide bar, a guide rail, a scissor push-pull rod, a roll extrusion mechanism, a spur gear, a rack, a drive shaft, and bearings. The adhesive is loaded into a rod-shaped HDPE plastic packaging bag for use. Except for the scraper, the other mechanisms have no direct contact with the adhesive.

[0006] Furthermore, the adhesive application lifting platform is equipped with a detachable scraper, a roller extrusion mechanism, a spur gear, a rack, and a track. The platform features multiple rows of holes, allowing the detachable scraper to be freely arranged and its spacing adjusted to accommodate different sizes of separator plates. The spur gear, rack, and track are fixed to the platform, with the roller extrusion mechanism working in conjunction with the track.

[0007] Furthermore, the base adopts a trolley-style structure design, with a push rod, front directional wheels and rear swivel wheels installed below, a ball screw, slide rods and guide rails installed above, and a pedal installed at the rear. Two front directional wheels are symmetrically installed on the left and right sides of the front underside of the base, and two rear swivel wheels are symmetrically installed on the left and right sides of the rear underside of the base. The ball screw is installed in the middle of the base, and a slide rod is installed on each side of the ball screw to support the lifting and lowering of the platform. A pedal is installed at the rear of the base, which can be stepped on to secure the rear swivel wheels.

[0008] Furthermore, the detachable scraper has a scraper surface that is connected by two planes, which allows the adhesive to have a place to stay and be stored, and edges are provided on both sides to prevent the coating from overflowing.

[0009] Furthermore, the aforementioned front directional wheel is fixedly installed under the base, and can only roll forward, not rotate left or right.

[0010] Furthermore, the rear swivel wheel consists of a mounting plate, a steering support plate, a bolt rod, a roller, a brake plate, and a spring. Depressing the pedal causes the brake plate to press down and contact the roller, thus applying the brakes. Releasing the pedal causes the spring to contract and pull the brake plate away, allowing normal movement.

[0011] Furthermore, the pedal is mounted on a protrusion at the rear of the base. When not in use, it forms an angle of approximately 45° with the horizontal plane for easy pressing. The pressure plate is bent and wrapped 180°, with soft rubber inside. When the pedal is pressed down, the pressure plate is pushed forward, and the soft rubber inside wraps around the rear caster to prevent it from rotating left or right. Pressing down the brake plate further applies braking, preventing the rear caster from rolling back and forth.

[0012] Furthermore, the servo motor is a servo motor with a rated power of 1.5kw, a rated speed of 3000r / min, and a rated torque of 5N·m, which has accurate positioning, sufficient torque reserve, and smooth start and stop.

[0013] Furthermore, the planetary reducer is selected as a 1:10 planetary reducer.

[0014] Furthermore, the coupling connects the planetary reducer and the transmission shaft for power transmission.

[0015] Furthermore, the two bevel gears transmit rotational speeds in a 1:1 ratio. The bevel gear mounted below the ball screw is secured with a round nut and a key. The bevel gear mounted on the drive shaft is secured using a shoulder, a key, and a sleeve.

[0016] Furthermore, a slide bar is installed on each side of the ball screw, and a lifting guide block is installed on the middle ball screw. The guide block is fixed to prevent it from rotating during the ascent and to expand the support area, making the gluing lifting platform more stable when it is raised and lowered. The mounting plate connects and fixes the three guide blocks.

[0017] Furthermore, the scissor push-pull mechanism consists of two guide channels, two scissor push-pull rods, and four rotatable spherical guide blocks. The two guide channels are installed left and right in a manner that is narrower at the top and wider at the bottom. As the lifting mechanism rises, it drives the scissor push-pull rods to rise as well. As the guide channels narrow, the scissor push-pull rods clamp and push the mechanism.

[0018] Furthermore, the roller extrusion mechanism is installed on the adhesive application lifting platform and consists of a roller and a rolling bar. The tail of the rod-shaped adhesive is inserted into the rolling bar, and the rod rotates within the roller to extrude the adhesive. The roller extrusion mechanism is combined with a scissor-type push-pull rod on its back. As the adhesive application lifting platform rises and falls, the entire roller extrusion mechanism is also propelled forward, ensuring the adhesive is extruded onto the detachable scraper. Simultaneously, a track is provided at the bottom of the roller extrusion mechanism, and a spur gear is installed on the rolling bar. A rack below the spur gear is fixed to the platform. When the roller extrusion mechanism moves forward, the gear and the rolling bar rotate as a whole under the action of the rack, causing the rod-shaped adhesive to be rolled and extruded.

[0019] This invention also discloses a non-contact anti-adhesion coating method for adhesives using the roll-type non-contact anti-adhesion coating device, comprising the following steps: S1) First, insert the tail of the rod-shaped rubber into the coil, and place the head of the coil on the top of the detachable scraper. S2) Start the servo motor. The servo motor drives the ball screw to rotate through the planetary reducer, coupling, transmission shaft and bevel gear. When the ball screw rotates, it drives the lifting guide block and the glue application lifting platform to move upward. S3) The adhesive application lifting platform moves upward, simultaneously driving the scissor push rod to rise. As the guide narrows, the scissor push rod clamps and pushes the drum forward. When the drum moves forward, the meshing of the spur gear on the drum rod with the rack below causes the drum rod to rotate while moving forward. When the drum rod rotates, it squeezes the stick-shaped adhesive material. While the drum moves forward, the position of the stick-shaped adhesive material relative to the detachable scraper remains unchanged. Since the adhesive material is packaged in a stick-shaped HDPE plastic bag, only the detachable scraper contacts the adhesive material during the entire process. Other mechanisms, including the drum and the drum rod, do not contact the adhesive material, thus achieving non-contact, anti-sticking adhesive application.

[0020] The beneficial effects of this invention are: 1) This invention employs a linkage design between a servo motor, a lifting mechanism, a roll extrusion mechanism, a glue-applying lifting platform, and a scissor-pull mechanism. This allows a single servo motor to simultaneously drive the following synchronous operations: driving the glue-applying lifting platform upwards while performing glue application; the scissor-pull mechanism driving the roll forward as the glue-applying lifting platform rises; and the roll extruding glue onto a detachable scraper while moving forward. This design not only significantly improves the stability of the glue-applying process but also significantly reduces the number of motors required, greatly reducing the manufacturing cost of the device.

[0021] 2) The isolated design of the colloidal material and the core extrusion device reduces the risk of component damage and lowers maintenance costs. Applying the adhesive material, packaged in rod-shaped HDPE plastic and extruded from a roll, solves the problems of clogging and adhesion caused by the high final bond strength of residual ALC-specific bonding mortar. Furthermore, the innovative structure can cover adhesive materials of various viscosities, offering a wider range of applications than traditional methods. The device adopts a trolley-style structure design, providing excellent mobility and flexible pushing operation. A brake pedal is located at the rear; pressing the pedal stops and secures the device, making operation simple and efficient. The modular design of the scraper allows for the integration of different scraper types for new application scenarios. Attached Figure Description

[0027] like Figures 1-9As shown, the present invention discloses a roll-type non-contact anti-adhesion adhesive application device, which consists of an adhesive application lifting platform 1, a base 2, a housing 3, a detachable scraper 4, a front directional wheel 5, a rear universal wheel 6, a pedal 7, a servo motor 8, a planetary reducer 9, a coupling 10, a bevel gear 11, a ball screw 12, a slide bar 13, a guide rail 14, a scissor push-pull rod 15, a roll extrusion mechanism 16, a spur gear 17, a rack 18, a transmission shaft 19, and a bearing 20. The adhesive is loaded into a rod-shaped HDPE plastic packaging bag for use. Except for the scraper, the other mechanisms have no direct contact with the adhesive.

[0028] Furthermore, the adhesive application lifting platform 1 is equipped with a detachable scraper 4, a roller extrusion mechanism 16, a spur gear 17, a rack 18, and a track 22. The adhesive application lifting platform 1 is designed with multiple rows of holes, allowing the detachable scraper 4 to be freely arranged on the platform, adjusting the front-to-back and left-to-right spacing to accommodate different sizes of isolation plates. The spur gear 17, rack 18, and track 22 are fixed to the adhesive application lifting platform 1, and the roller extrusion mechanism 16 cooperates with the track 22.

[0029] Furthermore, the base 2 adopts a trolley-type structure design, with a push rod, front directional wheels 5 and rear omnidirectional wheels 6 installed below, a ball screw 12, a slide bar 13 and a guide rail 14 installed above, and a pedal 7 installed at the rear. Two front directional wheels 5 are symmetrically installed on the left and right sides of the front underside of the base 2, and two rear omnidirectional wheels 6 are symmetrically installed on the left and right sides of the rear underside of the base 2. The ball screw 12 is installed in the middle of the base 2, and a slide bar 13 is installed on each side of the ball screw 12 to support the lifting and lowering of the platform. A pedal 7 is installed at the rear of the base 2, which can be stepped on to fix the rear omnidirectional wheels 6.

[0030] Furthermore, the detachable scraper 4 has a scraper surface connected by two planes, which allows the adhesive to have a place to stay and be stored, and edges are set on both sides to prevent the coating from overflowing.

[0031] Furthermore, the front directional wheel 5 is fixedly installed under the base and can only roll forward, not rotate left or right.

[0032] Furthermore, the rear swivel wheel 6 is composed of a mounting plate 23, a steering support plate 24, a bolt rod 25, a roller 26, a brake plate 27, and a spring 28. When the pedal 7 is pressed down, the brake plate 27 is pressed down to contact the roller 26, thus braking. When the pedal 7 is released, the spring 28 retracts and pulls the brake plate 27 away, allowing normal movement.

[0033] Furthermore, the pedal 7 is mounted on the rear protrusion of the base 2. When not in use, it forms an angle of approximately 45° with the horizontal plane for easy pressing. The pressure plate 28 is bent and wrapped 180°, with soft rubber inside. When the pedal 7 is pressed down, the pressure plate 29 is pushed forward, and the soft rubber inside wraps around the rear caster 6 to prevent it from rotating left or right. Pressing down the brake plate 27 further applies braking, preventing the rear caster 6 from rolling back and forth.

[0034] Furthermore, the servo motor 8 is a servo motor with a rated power of 1.5kw, a rated speed of 3000r / min, and a rated torque of 5N·m, which has accurate positioning, sufficient torque reserve, and smooth start and stop.

[0035] Furthermore, the planetary reducer 9 is selected as a 1:10 planetary reducer.

[0036] Furthermore, the coupling 10 connects the planetary reducer 9 and the transmission shaft 19 for power transmission.

[0037] Furthermore, the two bevel gears 11 transmit rotational speed in a 1:1 ratio. The bevel gear 11 mounted below the ball screw 12 is fixed with a round nut 31 and a key. The bevel gear 11 mounted on the transmission shaft 19 is fixed with a shoulder, a key, and a sleeve 30.

[0038] Furthermore, a slide bar 13 is installed on each side of the ball screw 12, and a lifting guide block 34 is installed on the middle ball screw 12. The guide block 33 is fixed to prevent the guide block from rotating during the rise and to expand the support area, so that the glue application lifting platform 1 is more stable when it rises and falls. The mounting plate 32 connects and fixes the three guide blocks.

[0039] Furthermore, the scissor push-pull mechanism consists of two guide channels 14, two scissor push-pull rods 15, and four rotatable spherical guide blocks 35. The two guide channels 14 are installed left and right in a way that is narrower at the top and wider at the bottom. When the lifting mechanism rises, it drives the scissor push-pull rods 15 to rise. As the guide channels 14 narrow, the scissor push-pull rods 15 clamp and push.

[0040] Furthermore, the roller extrusion mechanism 16 is installed on the adhesive application lifting platform 1 and consists of a roller and a roller rod 21. When the roller is opened, the tail of the rod-shaped adhesive is fixed to the roller rod 21. As the roller rod 21 rotates within the roller, the adhesive is extruded. The roller extrusion mechanism 16 is combined with a scissor-type push-pull rod 15 on its back. As the adhesive application lifting platform 1 rises and falls, the roller extrusion mechanism 16 is also pushed forward, ensuring the adhesive is extruded onto the detachable scraper 4. Simultaneously, a track 22 is provided at the bottom of the roller extrusion mechanism 16, and a spur gear 17 is installed on the roller rod 21. A rack 18 is fixed to the platform below the spur gear 17. When the roller extrusion mechanism 16 moves forward, under the action of the rack 18, the gear 17 and the roller rod 21 rotate as a unit, causing the rod-shaped adhesive to be rolled and extruded.

[0041] When using this device, place it in the work area, step on pedal 7 to fix the rear casters 6, thus securing the device. Servo motor 8 starts, reducing its speed via planetary reducer 9. Power travels through coupling 10 and drive shaft 19 to bevel gear 11, which in turn rotates ball screw 12. The adhesive application lifting platform 1 rises, and under the pressure of the narrow-at-the-top, wide-at-the-bottom guide channel 14, scissor-type push-pull rod 15 pushes the roller extrusion mechanism 16 forward. During this forward movement, spur gear 17 and rack 18 mesh, causing spur gear 17 and roller 21 to rotate. The tail of the rod-shaped adhesive is fixed to the roller 21, rotating within the roller extrusion mechanism 16 to extrude the adhesive, which is then scraped evenly onto the detachable scraper 4. This device is easy to stop and pull, allowing for precise control of the distance from the wall to ensure the desired amount of adhesive is applied.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
