Description

Technical Field

[0001] This invention specifically relates to a door pressing device with an adhesive overflow removal function. Background Technology

[0002] In the wooden door manufacturing process, the pressing process is at the core, directly determining the structural strength, flatness, and lifespan of the door panel, and is a key step in ensuring the quality of the finished door. The core principle of this process is to use preset pressure to tightly bond the various layers of the door panel with the adhesive, eliminating gaps between the layers.

[0003] In practice, workers first stack the layers of substrate coated with adhesive onto the machine's support platform according to process requirements. Then, the control system is activated, and a cylinder drives the pressure block vertically downwards until the pressure block is completely adhered to the door panel surface and stable pressure is applied. During this process, the adhesive fully penetrates into the gaps in the substrate texture under pressure, and after curing, a structurally stable integral door panel is formed.

[0004] For example, Chinese invention patent with publication number CN110027062A provides a fully automatic door panel hot press gluing machine. This device can accurately position the unpressed door panel fed into the feeding conveyor line at the corresponding processing position of the hot press plate through the feeding rod on the feeding device. It can ensure that door panels with flat surfaces, door panels with uneven surfaces with anti-pry covers, mother and daughter door panels with uneven surfaces with anti-pry covers, and paint-free door panels can all be processed on the line.

[0005] Because adhesive is used for pressing wooden doors, it easily overflows from the edges of the door panels under pressure. With existing devices, workers must manually clean up the excess adhesive with a scraper after pressing, resulting in only a small number of doors that can be cleaned per person per day. This is labor-intensive and inefficient. Furthermore, excess adhesive drips onto the equipment surface and floor during pressing, causing contamination of the work area and requiring additional manpower for cleaning. Therefore, a door pressing device with an adhesive overflow removal function is proposed to solve these problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention proposes a door pressing device with adhesive overflow removal function. This solves the technical problem mentioned in the background art that most existing door pressing devices do not have the function of removing adhesive overflow, which leads to the need for workers to manually clean the adhesive overflow on the door edges after pressing, increasing the labor intensity of workers. Furthermore, excessive adhesive overflow during the pressing process can also cause pollution to the work area.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a door pressing device with adhesive overflow removal, comprising a frame, wherein the frame is provided with a pressing block mounted via a support platform and a cylinder, and a removal unit is provided around the support platform on the frame, the removal unit comprising: A mounting frame is mounted on the machine frame, and a housing is mounted on the mounting frame that can be raised and lowered. A scraping mechanism is installed inside the housing. A drive mechanism is disposed on the housing to drive the scraping mechanism to move intermittently in a circumferential direction; A transmission mechanism, mounted on the mounting bracket and connected to the housing, converts the power of the drive mechanism into the power to intermittently raise and lower the housing when the scraping mechanism is not in motion; and A cleaning mechanism is disposed within the housing and connected to the scraping mechanism.

[0008] In a preferred embodiment, the scraping mechanism includes: Two sets of rollers, spaced apart and rotatable, are disposed within the housing; the two sets of rollers are connected by a conveyor belt. Multiple sets of mounting bases are provided and evenly spaced on the conveyor belt. Each mounting base is equipped with a detachable scraper, with the outermost set of scrapers extending out of the housing opening.

[0009] In a preferred embodiment, the drive mechanism includes: A drive motor is fixedly mounted on the housing, and its output shaft is provided with a drive disc, with a drive column eccentrically mounted on one side of the drive disc; and The control panel is located at the end of one of the rollers and has multiple sets of sliding grooves circumferentially formed, with the drive column slidably engaged in the sliding grooves.

[0010] In a preferred embodiment, the transmission mechanism includes: A sector gear is mounted on the drive disc; A drive gear is rotatably mounted on the housing and can mesh with the sector gear; and A rack is mounted on the frame and is vertically connected to the housing; the drive gear meshes with the rack.

[0011] In a preferred embodiment, the mounting bracket has a positioning groove, and the rack has a positioning block, which is slidably engaged in the positioning groove.

[0012] In a preferred embodiment, the housing and the mounting bracket are connected by a guide assembly, which drives the rack to slide toward the support when the housing is raised and to slide away from the support when the housing is lowered.

[0013] In a preferred embodiment, the guiding component includes: A vertical plate is mounted on the mounting bracket; Two sets of straight tracks are arranged at intervals, and both are located on one side of the vertical plate; Two sets of inclined tracks are arranged at intervals, and each end of the inclined track is connected to one of the two sets of straight tracks. One end of the inclined track is connected to one end of the straight track via a step. The guide post is slidably inserted through the end of one of the sets of rollers by means of a spring, and is slidably engaged within one of the sets of straight tracks.

[0014] In a preferred embodiment, the cleaning mechanism includes: The mounting frame is disposed within the housing; A cleaning knife is disposed inside the housing, and a collection groove is provided on one side of it. The collection groove is connected to the outside of the housing through a pipe. A slider is provided at the end of the collection groove, and the slider is slidably engaged in the mounting frame. An elastic element is disposed between the slider and the mounting frame; and A linkage component is disposed within the housing and connected to the mounting frame to convert the rotation of the drive gear into a circumferential translation of the mounting frame. During the translation of the mounting frame, the cleaning blade abuts against the innermost set of scrapers.

[0015] In a preferred embodiment, the linkage component includes: Two sets of synchronous pulleys are provided, and both sets are rotatably disposed inside the housing. One set of synchronous pulleys is coaxially connected to the drive gear.

The pressing block is moved down by the cylinder to press the door panel. During the pressing process, the scraping mechanism is controlled by the drive mechanism to move intermittently to remove excess glue from the edge of the door panel. When the scraping mechanism is not moving, the transmission mechanism converts the power of the drive mechanism into the intermittent lifting and lowering of the drive housing, so that the scraping mechanism and the edge of the door panel move relative to each other, improving the cleaning effect. After the scraping mechanism removes the excess glue from the edge of the door panel, the excess glue adheres to the scraping mechanism and is moved into the housing by the drive mechanism. The cleaning mechanism can remove the glue on the scraping mechanism to avoid secondary pollution. This device can effectively remove excess glue from the door panel, reduce the rework of the door panel caused by excess glue residue, and reduce labor costs and production losses by combining automated operation characteristics, avoiding pollution to the working environment, which meets the industry demand for improving the quality and efficiency of wooden door production.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0022] Example: like Figures 1 to 3 As shown, the present invention provides a door pressing device with glue overflow removal, including a frame 1, on which a pressing block 4 is installed via a support platform 2 and a cylinder 3. When in use, the door panel and door core to be pressed can be placed on the support platform 2, and the pressing block 4 is controlled by the cylinder 3 to move down to press the door panel.

[0023] Cleaning units are provided around the support platform 2 on the frame 1. Each cleaning unit includes a mounting frame 5 on the frame 1. A housing 12 is mounted on the mounting frame 5 and can be raised and lowered. A scraping mechanism is provided inside the housing 12. The scraping mechanism includes two sets of spaced rollers 13. The rollers 13 are rotatably mounted inside the housing 12. The two sets of rollers 13 are connected by a conveyor belt 14. Multiple sets of mounting seats 15 are evenly spaced on the conveyor belt 14. Removable scraper strips 16 are provided on the mounting seats 15. The outermost set of scraper strips 16 extends out of the opening of the housing 12.

[0024] The excess adhesive on the edge of the door panel can be removed by raising the housing 12 and driving the scraper 16 to rise. The scraper 16 can also be moved into the housing 12 by controlling the roller 13 to rotate, so that the scraper 16 used each time is a newly extended scraper 16 outside the housing 12, thereby improving the cleaning effect and avoiding secondary pollution.

[0025] like Figure 5 , 6As shown, in this embodiment, a drive mechanism is provided on the housing 12. The drive mechanism drives the scraping mechanism to move intermittently in a circumferential direction. The drive mechanism includes a drive motor 20 fixedly mounted on the housing 12. The output shaft of the drive motor 20 is provided with a drive disk 21. A drive column 22 is eccentrically provided on one side of the drive disk 21. A control disk 17 is provided at the end of a set of rollers 13. The control disk 17 has multiple sets of sliding grooves in a circumferential direction. The drive column 22 is slidably locked in the sliding groove.

[0026] The drive motor 20 can be started to drive the drive disk 21 to rotate. During the rotation of the drive disk 21, the drive column 22 and the slide groove can drive the control disk 17 to rotate intermittently. The control disk 17 rotates at the same angle each time and can make the mounting base 15 move to coincide with the position of the previous set of mounting bases 15, thereby ensuring the continuous scraping effect.

[0027] like Figure 5 , 6 As shown, in this embodiment, the mounting frame 5 is provided with a transmission mechanism connected to the housing 12. When the scraping mechanism is not moving, the transmission mechanism converts the power of the drive mechanism into the intermittent lifting and lowering of the housing 12. The transmission mechanism includes a sector gear 23 provided on the drive disk 21, and a drive gear 24 rotatably provided on the housing 12. The drive gear 24 can mesh with the sector gear 23. A rack 10 is provided on the frame 1. The rack 10 is vertically connected to the housing 12, and the drive gear 24 meshes with the rack 10.

[0028] During the rotation of the drive disc 21, the sector gear 23 intermittently meshes with the drive gear 24. When the sector gear 23 meshes with the drive gear 24, it drives the housing 12 to rise, causing the non-rotating scraper 16 to rise and scrape off the excess glue. When the sector gear 23 disengages from the drive gear 24, the housing 12 automatically descends. When the housing 12 descends and rises again, the scraper 16 moves, thereby repeatedly scraping the edge of the door panel and improving the cleaning effect.

[0029] like Figure 2 , 4As shown in Figures 7 and 8, in this embodiment, the mounting frame 5 has a positioning groove 6, and the rack 10 has a positioning block 11, which is slidably engaged in the positioning groove 6. The housing 12 is connected to the mounting frame 5 through a guide assembly. When the housing 12 rises, the guide assembly drives the rack 10 to slide towards the support platform 2, and when the housing 12 falls, it drives the rack 10 to slide away from the support platform 2. The guide assembly includes a vertical plate 7 on the mounting frame 5. Two sets of straight rails 8 and inclined rails 9 are provided on one side of the vertical plate 7. The two ends of the inclined rails 9 are respectively connected to the two sets of straight rails 8. One end of the inclined rails 9 is connected to one end of the straight rails 8 through a step. One set of rollers 13 has a guide post 18 slidably inserted through the end of a spring, and the guide post 18 is slidably engaged in one set of straight rails 8.

[0030] When the housing 12 rises, the guide post 18 slides in a set of straight tracks 8 near the door panel so that the scraper 16 can contact the edge of the door panel. When the housing 12 rises to its limit position, the guide post 18 and the inclined track 9 work together to drive the rack 10 and the housing 12 to shift laterally at the same time. Under the action of the steps, the guide post 18 can only slide unidirectionally within the frame formed by the straight track 8 and the inclined track 9. When the housing 12 falls, the guide post 18 can slide in another set of straight tracks 8, so that the scraper 16 is away from the edge of the door panel, preventing the glue scraped off on the scraper 16 from adhering to the door panel again and improving the cleaning effect.

[0031] like Figure 3 , 5 As shown in Figure 6, in this embodiment, a cleaning mechanism connected to the scraping mechanism is provided inside the housing 12. The cleaning mechanism includes a mounting frame 28 provided inside the housing 12, a cleaning blade 30 provided inside the housing 12, a collection groove 29 provided on one side of the cleaning blade 30, the collection groove 29 being connected to the outside of the housing 12 through a pipe 34, a slider 31 provided at the end of the collection groove 29, the slider 31 being slidably engaged inside the mounting frame 28, an elastic element 32 being provided between the slider 31 and the mounting frame 28, and a linkage assembly connected to the mounting frame 28 provided inside the housing 12. The rotation of the drive gear 24 is converted into a circumferential translation of the mounting frame 28 through the linkage assembly. When the mounting frame 28 is translated, the cleaning blade 30 abuts against the innermost set of scraping strips 16.

[0032] The linkage assembly includes two sets of rotatable synchronous pulleys 25 disposed in the housing 12. One set of synchronous pulleys 25 is coaxially connected to the drive gear 24. Synchronous belts 26 are sleeved on both sets of synchronous pulleys 25. Rocker arms 27 are fixedly disposed on both sets of synchronous pulleys 25. The two sets of rocker arms 27 are arranged in parallel. The mounting frame 28 is hinged to the ends of the two sets of rocker arms 27.

[0033] During rotation, the drive gear 24 drives one set of synchronous pulleys 25 to rotate, and under the action of the synchronous belt 26, the two sets of rocker arms 27 rotate synchronously. During this movement, the two sets of rocker arms 27 control the circumferential movement of the mounting frame 28, allowing the cleaning blade 30 to contact the scraping surface of the inner set of scraper blades 16 and move laterally to remove the adhesive adhering to the scraper blades 16, allowing the adhesive to flow into the collection tank 29 for recycling. The arrangement of the elastic element 32 ensures that the cleaning blade 30 can fully contact the scraper blades 16 and maintain a certain pressure, improving the scraping effect.

[0034] Furthermore, a stop bar 19 flush with the end face of the innermost set of mounting seats 15 is provided inside the housing 12, and a stop block 33 is provided on the cleaning knife 30, which can abut against the mounting seat 15. When the stop block 33 abuts against the stop bar 19, it can drive the collection groove 29 to slide and compress the elastic element 32. The stop bar 19 can guide the movement of the stop block 33, avoiding the mounting seat 15 from obstructing the movement of the cleaning knife 30, thereby improving the stability and reliability of the internal structure of the device.

[0035] Specific usage and beneficial effects of the present invention: When in use, the door panel and door core to be pressed are placed on the support platform 2. The cylinder 3 controls the pressing block 4 to move down to perform the door panel pressing work. During the pressing process, the drive mechanism controls the scraping mechanism to move intermittently to remove excess glue from the edge of the door panel. The transmission mechanism can also convert the power of the drive mechanism into the intermittent lifting and lowering of the housing 12 when the scraping mechanism is not moving, so that the scraping mechanism and the edge of the door panel move relative to each other, improving the cleaning effect. After the scraping mechanism removes the excess glue from the edge of the door panel, the excess glue adheres to the scraping mechanism and is moved into the housing 12 by the drive mechanism. The cleaning mechanism can remove the glue on the scraping mechanism to avoid secondary pollution. This device can effectively remove excess glue from the door panel, reduce the rework of the door panel caused by excess glue residue, and reduce labor costs and production losses by combining automated operation characteristics, avoiding pollution to the working environment, which meets the industry demand for improving the quality and efficiency of wooden door production.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
