Description

Technical Field

[0001] This invention relates to the field of adhesive application technology, and in particular to an apparatus for applying adhesive to composite boards using scrap materials. Background Technology

[0002] The core of composite board adhesive application lies in the precise control of adhesive mixing, uniform coating, and appropriate pressure curing process to ensure interlayer bonding strength. Adhesive mixing and coating are fundamental. After uniform mixing, the adhesive is brushed on, controlling the amount and ensuring that the adhesive is evenly distributed on the bonding surface. There are various coating methods, including automatic roller glue machines and glue spraying machines, which can effectively improve efficiency and uniformity. After applying the adhesive, the composite process must be completed within the adhesive's open time and then sent to the press for board processing.

[0003] The core component of a glue coating machine is the glue coating assembly, which mainly consists of two parts: the glue coating head and the glue supply system. The glue coating head is the part that directly performs the coating operation to achieve a stable coating effect. The glue supply system is responsible for continuously and stably supplying glue to the glue coating head. It typically includes a storage tank, a metering pump (such as a screw pump or gear pump), a mixing device, and heating and stirring functions.

[0004] In the process of applying adhesive to composite boards, the boards to be processed are placed on a conveyor table. As they pass through the adhesive applicator, the applicator uses a detection mechanism to determine the width of the board and applies adhesive repeatedly. The adhesive flows out from the outlet of the applicator component, evenly applying adhesive to the board. During this process, after each application of adhesive, the adhesive remaining at the bottom outlet needs to be cleaned and collected in a timely manner. This is to prevent the adhesive from adhering to the outlet and solidifying, which could cause blockage. Additionally, the adhesive adhering to the outlet may drip, resulting in waste.

[0005] To address these issues, this invention proposes a device for applying adhesive to composite board materials made from scraps to form boards. Summary of the Invention

[0006] The purpose of this invention is to provide an apparatus for applying adhesive to composite board materials made from scrap materials, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for processing composite board scraps into boards by applying adhesive, comprising a conveyor table and an adhesive coating mechanism disposed on the conveyor table, wherein the conveyor table conveys the board to be processed to the adhesive coating mechanism for adhesive coating processing; A glue outlet for dispensing glue is provided at the bottom of the glue dispensing mechanism; An electrically controlled slide rail is provided at the bottom of the glue coating mechanism. A slide body is provided on the electrically controlled slide rail. The slide body is connected to a support strip. The support strip is used to connect the glue coating auxiliary components. This adhesive application auxiliary component is used to clean and collect the adhesive adhering to the dispensing nozzle, so as to prevent the adhesive from curing and clogging at the dispensing nozzle and to avoid adhesive dripping and waste.

[0008] Preferably, the adhesive coating auxiliary component includes a loading strip that is fixedly connected to the support strip by screws; A cleaning scraper is symmetrically fixed on both sides of the top of the support strip. The cleaning scraper is used to scrape off the adhesive that adheres to the glue outlet.

[0009] Preferably, a guide slope is also provided on the bottom side of the cleaning scraper body. The guide slope is used to provide a guiding effect for the scraped adhesive to avoid the adhesive from falling after scraping. A flow-limiting side frame is symmetrically provided on both sides of the flow-guiding slope. The flow-limiting side frame is used to limit the scraped adhesive to prevent the adhesive from overflowing from both sides of the flow-guiding slope.

[0010] Preferably, guide cones are also fixedly provided at equal intervals on the bottom side of the guide slope; The tip of the guide cone is set vertically downward. The guide cone provides a blocking and guiding effect for the adhesive liquid on the guide slope, so that the adhesive liquid drips vertically downward.

[0011] Preferably, a collection box is provided directly below the cleaning scraper, which serves to collect the adhesive scraped off by the cleaning scraper.

[0012] Preferably, the collection box consists of a receiving ramp and a confluence bottom; The receiving ramps are symmetrically arranged on both sides of the bottom of the confluence, and both the receiving ramps and the bottom of the confluence are connected to the flow-limiting side frame.

[0013] Preferably, the collection chamber of the collection box is formed by the space enclosed by the receiving inclined plate, the flow-gathering bottom, and the flow-limiting side frame; The collection chamber provides a temporary collection effect for the scraped adhesive.

[0014] Preferably, the end sections of the receiving sloping plate and the bottom of the confluence form a V-shape.

[0015] Preferably, the top of the receiving inclined plate extends beyond the end of the cleaning scraper; this ensures the smooth receiving of the scraped adhesive.

[0016] Preferably, a discharge port is provided at the bottom of the confluence, and the discharge port is connected to the collection chamber in the collection box; The discharge port is connected to the conveying hose via a connecting screw.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention discloses a composite board processing device for applying adhesive to scrap materials. The device includes a conveyor table and an adhesive coating mechanism mounted on the conveyor table. The conveyor table transports the board to be processed to the adhesive coating mechanism for adhesive coating. An adhesive outlet is located at the bottom of the adhesive coating mechanism. An electrically controlled slide rail is located at the bottom of the adhesive coating mechanism, and a sliding seat is mounted on the slide rail. The sliding seat is connected to a support strip, which is used to connect an adhesive coating auxiliary component. This adhesive coating auxiliary component provides a cleaning and collection function for the adhesive adhering to the outlet, preventing the adhesive from solidifying and clogging at the outlet and avoiding adhesive dripping and waste. After a glue coating process is completed, the glue coating auxiliary component is moved by a sliding body to scrape and collect the glue adhering to the glue outlet at the bottom of the glue coating mechanism. This prevents the glue from solidifying and clogging at the outlet and avoids glue dripping and wasting. In other words, the sliding body moves the cleaning scraper to scrape off the glue adhering to the outlet or the glue that has not dripped. As the cleaning scraper moves and passes the outlet, it scrapes off the glue that is coming out of the outlet. Based on this, after the adhered adhesive is scraped off, a collection box is set up to provide temporary collection of the scraped adhesive. That is, the adhesive enters the collection chamber of the collection box, which is formed by the space enclosed by the receiving inclined plate, the confluence bottom, and the flow-limiting side frame. This collection chamber provides a temporary collection effect for the scraped adhesive. The collected adhesive flows to the bottom of the inner cavity of the collection box, and then is transported and stored through the conveying hose for subsequent centralized processing, so as to avoid adhesive waste and improve its processing efficiency.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-12 A composite board processing device for applying glue to scrap materials includes a conveying table 1 and a glue-applying mechanism 3 disposed on the conveying table 1. The conveying table 1 conveys the board to be processed 2 to the glue-applying mechanism 3 for glue-applying processing. A glue outlet 31 for dispensing glue is provided at the bottom end of the glue-applying mechanism 3. An electrically controlled slide rail 401 is provided at the bottom of the glue-spreading mechanism 3. A slide body 402 is provided on the electrically controlled slide rail 401. The slide body 402 is connected to a support strip 403. The support strip 403 is used to connect the glue-spreading auxiliary component. The glue-spreading auxiliary component is used to clean and collect the glue adhering to the glue outlet 31, so as to avoid the glue from curing and clogging at the glue outlet 31 and to avoid glue dripping and wasting.

[0022] According to the appendix Figure 1-5As shown, during the glue application process of the board 2 to be processed, after one glue application is completed, the glue adhering to the glue outlet 31 at the bottom of the glue application mechanism 3 is scraped off and collected in time by the sliding body 402 driving the glue application auxiliary component to avoid the glue from solidifying and clogging at the glue outlet 31 and to avoid glue dripping and wasting; that is, the sliding body 402 drives the cleaning scraper 501 to scrape off the glue adhering to the glue outlet 31 or the glue that has not dripped. In addition, after the adhesive is scraped off, a collection box is provided to temporarily collect the scraped adhesive. The adhesive enters the collection chamber of the collection box and flows to the bottom of the inner cavity of the collection box. Then it is transported through the delivery hose 702 to avoid waste of adhesive and improve processing efficiency.

[0023] Combined with the appendix Figure 6-7 and appendix Figure 9-11 As shown, the adhesive application auxiliary component includes a loading strip 502 that is fixedly connected to the support strip 403 by screws; cleaning scrapers 501 are symmetrically fixed on both sides of the top of the support strip 403, which are used to scrape off the adhesive adhering to the dispensing port 31; a guide slope 503 is also provided on the bottom side of the cleaning scraper 501, which is used to guide the scraped adhesive to avoid the adhesive falling off after scraping.

[0024] From the appendix Figure 11 As shown, the loading bar 502 is fixedly connected to the support bar 403 by screws. When it is necessary to disassemble, clean or replace the cleaning scraper 501 and the collection box in the later stage, the connection between the loading bar 502 and the support bar 403 can be directly released, and then the cleaning scraper 501 and the collection box can be disassembled.

[0025] After the glue coating process on the board 2 to be processed is completed, and before the glue coating process on another board 2 to be processed, the glue adhering at the glue outlet 31 at the bottom of the glue coating mechanism 3 needs to be scraped off and collected in time to avoid the glue from solidifying and clogging at the glue outlet 31, or dripping onto the conveyor rollers on the conveyor table 1 and causing pollution, and also causing waste of glue. Therefore, the sliding body 402 and the support strip 403 will be moved along the length direction of the bottom of the glue coating mechanism 3 by the electronically controlled slide rail 401. Here, the electronically controlled slide rail 401 adopts a linear guide rail.

[0026] Combined with the appendix Figure 5As shown, the support strip 403 moves along the bottom of the glue application mechanism 3 with the glue application auxiliary component. The cleaning scraper 501, which is set in the glue application auxiliary component, contacts the bottom of the glue application mechanism 3. When the cleaning scraper 501 moves with the support strip 403, it scrapes off the glue at the glue outlet 31. In other words, it provides a scraping function for the glue that exceeds the glue outlet 31 to avoid the glue from solidifying or dripping and causing waste.

[0027] In this design, a flow-guiding slope 503 is provided on the bottom side of the cleaning scraper body 501, and flow-limiting side frames 504 are symmetrically provided on both sides of the flow-guiding slope 503. The flow-limiting side frames 504 are used to limit the scraped adhesive to prevent the adhesive from overflowing from both sides of the flow-guiding slope 503. Flow-guiding cones 505 are also fixedly provided at equal intervals on the bottom side of the flow-guiding slope 503. The cone tip of the flow-guiding cone 505 is set vertically downwards, and the flow-guiding cone 505 provides a blocking and guiding effect for the adhesive on the flow-guiding slope 503 so that the adhesive drips vertically downwards.

[0028] The collection box is located directly below the cleaning scraper 501. This collection box is used to collect the adhesive scraped by the cleaning scraper 501. In other words, when the cleaning scraper 501 moves and passes the adhesive outlet 31, it scrapes off the adhesive coming out of the adhesive outlet 31. During this process, the scraped adhesive will flow down the guide slope 503.

[0029] From the appendix Figure 8-9 As shown, in order to further increase the falling speed of the adhesive flowing through the guide slope 503, this solution also provides multiple sets of guide cones 505 on the guide slope 503. When the adhesive reaches the position of the guide cone 505, the adhesive falls vertically along the guide cone 505 so as to enter the collection box more quickly.

[0030] Combined with the appendix Figure 10 As shown, this illustrates the use of the collection box.

[0031] The collection box consists of a receiving ramp 601 and a confluence bottom 602. The receiving ramp 601 is symmetrically arranged on both sides of the confluence bottom 602, and both the receiving ramp 601 and the confluence bottom 602 are connected to the flow-limiting side frame 504. The collection cavity of the collection box is formed by the space enclosed by the receiving ramp 601, the confluence bottom 602, and the flow-limiting side frame 504. The collection cavity provides a temporary collection effect for the scraped adhesive. The end sections of the receiving ramp 601 and the confluence bottom 602 form a V-shape. The purpose of setting the V-shape here is that when the adhesive scraped by the cleaning scraper 501 falls onto the receiving ramp 601, the adhesive will flow along the ramp of the receiving ramp 601 to the confluence bottom 602 in the collection box.

[0032] After the adhesive is scraped off by the cleaning scraper 501, the adhesive flows through the guide slope 503 and the guide cone 505. The adhesive dripping from the bottom tip of the guide cone 505 falls onto the receiving slope 601. Then the adhesive collects along the receiving slope 601 at the bottom 602 of the confluence, which provides a temporary collection function for the scraped adhesive and prevents the adhesive scraped off by the cleaning scraper 501 from falling onto the working equipment or the ground.

[0033] Combined with the appendix Figure 2 and attached Figure 8 As shown, the adhesive collected in the collection box needs to be recycled or stored centrally for subsequent centralized processing.

[0034] Therefore, this solution also provides a discharge port 701 at the bottom of the confluence bottom 602, which is connected to the collection chamber in the collection box. The discharge port 701 is connected to the conveying hose 702 via a connecting screw 703. That is, the glue scraped off by the cleaning scraper 501 is finally collected at the confluence bottom 602 in the collection box. Then the glue flows out from the discharge port 701 into the conveying hose 702. The other end of the conveying hose 702 can be connected to a storage container to centrally store the glue collected in the collection box for subsequent centralized processing.

[0035] Here, a discharge port 701 is connected to the bottom side of the bottom 602 of the confluence, and the adhesive is discharged through the conveying hose 702. The purpose is to treat the adhesive collected in the collection box in a timely manner, so as to avoid the adhesive after scraping filling the collection box and overflowing outward, and to prevent the adhesive from solidifying. It also eliminates the need to frequently disassemble the adhesive application auxiliary component to clean the adhesive collected therein, thus reducing the frequency of disassembly.

[0036] Combined with the appendix Figure 11-12 As shown, after prolonged use, it may be necessary to clean the cleaning scraper 501 and the collection box in the glue application auxiliary component. At this time, the glue application auxiliary component can be disassembled. The fixed connection between the loading strip 502 and the support strip 403 is released. Then, the cleaning scraper 501 and the collection box are pulled vertically down until the glue application auxiliary component is removed. After cleaning the glue application auxiliary component, it can be installed on the support strip 403.

[0037] For the installation of the adhesive coating auxiliary components, combined with the attached... Figure 5 and attached Figure 8As shown, cleaning scrapers 501 are symmetrically arranged on both sides of the top of the loading strip 502, and a mounting groove is formed between the two cleaning scrapers 501. When installing the glue application auxiliary component, the mounting groove is directly snapped onto the support strip 403 until the loading strip 502 and the support strip 403 are in close contact and the mounting holes on the loading strip 502 are aligned with the mounting screw grooves on the support strip 403. Then, the loading strip 502 is fixed with screws. The installation of the glue application auxiliary component is then completed, and the operation is convenient.

[0038] Then according to the appendix Figure 8-9 As shown, during the scraping and collection of adhesive at the outlet 31, that is, after the cleaning scraper 501 scrapes the adhesive that emerges from the outlet 31, as the adhesive accumulates, after the cleaning scraper 501 separates the emerging adhesive from the outlet 31, some adhesive may fall directly. Some adhesive will flow along the guide slope 503 on the bottom side of the cleaning scraper 501, while some will fall directly. To collect the directly falling adhesive and prevent it from dripping onto the equipment or the ground and causing waste, the top of the receiving slope 601 in this solution extends beyond the end of the cleaning scraper 501, ensuring the proper collection of scraped adhesive.

[0039] In other words, during the process of scraping off the adhesive by the cleaning scraper 501 along the bottom moving rod of the adhesive spreading mechanism 3, with the moving direction of the cleaning scraper 501 as the front end, the front end of the receiving inclined plate 601 extends beyond the front end of the cleaning scraper 501. This ensures that after the cleaning scraper 501 scrapes off the adhesive emerging from the adhesive outlet 31, it can avoid the problem of missing the adhesive and provide a guarantee for the recycling of the adhesive. The adhesive that falls on the receiving inclined plate 601 then flows along its inclined surface to the bottom 602 of the collection box, and is then discharged in time through the discharge connection port 701.

[0040] After the cleaning scraper 501 moves from its initial position to the other end of the bottom of the glue-applying mechanism 3, the cleaning scraper 501 returns to its original position. During the return process, since the cleaning scraper 501 is provided on both sides of the loading strip 502 and the collection box is set in a V shape, the glue-applying auxiliary component will also perform a glue scraping and collection effect during the return. The back and forth of the glue-applying auxiliary component provides a complete glue scraping and collection process. After one process is completed, the glue-applying mechanism 3 will apply glue to the new board 2 to be processed. After the board 2 is glue-applying, the glue-applying auxiliary component will collect the glue that comes out of the glue outlet 31 through the electrically controlled slide rail 401.
