Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machine devices, in particular to a cleaning-free gluing component of a PUR edge banding machine. Background Art

[0002] PUR polyurethane hot melt adhesive is widely used in furniture, wooden panels, decorative materials, automotive interiors, aerospace, construction and other fields. In the production of furniture and panels, the gluing component of the PUR edge banding machine is mainly used to evenly apply the PUR hot melt adhesive on the back of the edge banding strip to ensure that the PUR hot melt adhesive is evenly applied on the back of the edge banding strip to achieve efficient and precise edge banding processing; however, the PUR hot melt adhesive is easy to solidify after coating. Using mechanical tools such as scrapers and scrapers to peel off the solidified PUR adhesive can easily cause damage to the gluing component. If the PUR adhesive in the gluing component has been completely solidified, the glue cartridge needs to be replaced.

[0003] The patent with publication number CN217915785U currently discloses a gluing component for a PUR edge banding machine, including a gluing box, in which a glue channel is provided, the glue channel is provided with a glue outlet and multiple glue inlets, the glue channel is provided with multiple glue inlet branches, the multiple glue inlet branches are connected to the multiple glue inlets one-to-one, and the gluing box is connected to a valve assembly on each glue inlet branch; a gluing roller, which is rotatably connected to the gluing box, and the gluing roller is directly opposite to the glue outlet; a glue scraper, which is rotatably connected to the gluing box, the glue scraper is located between the glue outlet and the glue roller, and a gap is left between the glue scraper and the glue roller, and the size of the gap is adjusted by rotating the glue scraper; although the above device improves the production flexibility of the edge banding machine.

[0004] However, the following problems still exist:

[0005] After the PUR edge banding machine stops operating, the hot melt adhesive on the gluing device will gradually solidify and harden after being in contact with the air for a certain period of time. When the PUR edge banding machine needs to be used again, the hot melt adhesive fixed on the gluing device needs to be removed with the assistance of spray guns, scrapers and other tools, which increases the difficulty of the staff's operation. At the same time, scrapers, spray guns and other tools may cause irreparable damage to the gluing device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a PUR edge banding machine gluing component that does not require cleaning, so as to at least solve one of the problems raised by the background technology, such as making the gluing component of the PUR edge banding machine easier to clean and gluing.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PUR edge banding machine cleaning-free gluing component, comprising an edge banding body, symmetrical feed rollers installed on one side of the edge banding body, an external material plate provided between the symmetrical feed rollers, a gluing mechanism installed on the other side of the edge banding body, one end of the gluing mechanism is fixedly connected to a hot melt glue tank and a control terminal installed on the top of the edge banding body, the gluing mechanism comprises a gluing roller, a glue guide roller and a glue spray head, the gluing roller is rotatably connected to the upper and lower inner walls of the edge banding body, the glue guide roller is rotatably connected to the upper and lower inner walls of the edge banding body, a blocking component is installed on one side of the gluing roller, a guide rail is provided on one side of the glue guide roller, a second scraper is slidably connected to the top of the guide rail, and a collecting box is installed on the side of the edge banding body close to the blocking component.

[0008] Furthermore, the blocking assembly includes a scraper, a baffle and a waste glue channel formed between the scraper and the baffle. The scraper and the baffle are arranged at an angle of 45 degrees, and the scraper is fitted and connected to the outer side of the glue coating roller.

[0009] Furthermore, one side of the second scraper is in close contact with the outer side of the rubber guide roller.

[0010] Furthermore, the glue coating roller, the glue guiding roller and the glue spraying head are arranged horizontally with the rolling direction of the feeding roller.

[0011] Furthermore, the output end of the glue spray head is aligned with the outer side of the glue guide roller.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model processes and collects the hot melt adhesive when the PUR edge banding machine is in use. When the PUR edge banding machine is stopped, the gluing component does not need to be cleaned and damage to the gluing component during the cleaning process can be prevented. At the same time, it is convenient for the staff to quickly enter the re-operation link of the PUR edge banding machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] like Figures 1 to 4 As shown, a PUR edge banding machine cleaning-free gluing component comprises an edge banding body 1, symmetrical feeding rollers 4 installed on one side of the edge banding body 1, an external material plate 7 is arranged between the symmetrical feeding rollers 4, a gluing mechanism 2 is installed on the other side of the edge banding body 1, one end of the gluing mechanism 2 is fixedly connected with a hot melt glue tank 3 and a control terminal 5 installed on the top of the edge banding body 1, the gluing mechanism 2 comprises a gluing roller 201, a glue guide roller 202 and a glue spray head 203, the gluing roller 201 is rotatably connected to the upper and lower inner walls of the edge banding body 1, the glue guide roller 202 is rotatably connected to the upper and lower inner walls of the edge banding body 1, a blocking component 8 is installed on one side of the gluing roller 201, a guide rail 204 is arranged on one side of the glue guide roller 202, a second scraper 205 is slidably connected to the top of the guide rail 204, and a collecting box 6 is installed on the side of the edge banding body 1 close to the blocking component 8.

[0021] like Figure 1 As shown, a PUR edge banding machine cleaning-free gluing component in the utility model is similar to the existing PUR edge banding machine gluing component structure, such as the PUR edge banding machine gluing component disclosed in the patent publication number CN217915785U. The main improvement of the utility model is to make the PUR edge banding machine free from cleaning the gluing component, such as Figures 1 to 4As shown, when a PUR edge banding machine cleaning-free gluing component in the utility model is in use, the staff puts the external material plate 7 on the surface of the feed roller 4, and then uses the control terminal 5 to move the external material plate 7 in the rolling direction of the feed roller 4, and one side of the external material plate 7 gradually approaches the gluing mechanism 2, and the glue in the hot melt glue tank 3 is squeezed to the glue spraying head 203, and the glue spraying head 203 sprays the glue to the outside of the glue guide roller 202, and the glue guide roller 202 scrapes the glue to the outside of the glue coating roller 201. When the external material plate 7 passes through the glue coating roller 201, one end of the external material plate 7 is rotated by the glue coating roller 201 and adhered to the glue and then transmitted to the bonding part of the edge banding machine body 1. The next step is carried out at the adhesive tape; after the glue coating roller 201 rotates to coat the glue on the external material plate 7, the excess glue is scraped off by the blocking component 8 and falls into the collecting box 6; and when it is necessary to stop using the PUR edge banding machine, the glue spray head 203 is closed to prevent the glue from appearing. At the same time, the glue on the glue coating roller 201 is continuously scraped into the collecting box 6, and the glue on the glue guide roller 202 gradually condenses. The staff pushes the second scraper 205 from the guide rail 204 to a state of fitting with the outer side of the glue guide roller 202, and then rotates the glue guide roller 202. The second scraper 205 scrapes off the solidified glue on the glue guide roller 202, and the operation of cleaning the glue coating mechanism 2 is completed.

[0022] like Figure 1 As shown, the blocking assembly 8 includes a scraper 801, a baffle 802 and a waste glue channel 803 formed between the scraper 801 and the baffle 802. The scraper 801 and the baffle 802 are arranged at an angle of 45 degrees, and the scraper 801 is fitted and connected to the outer side of the glue coating roller 201.

[0023] Specifically, through this arrangement, the glue scraped off from the glue coating roller 201 by the scraper 801 rolls into the collecting box 6 through the waste glue channel 803, and the baffle 802 prevents the scraped glue from entering the feeding roller 4 and affecting the gluing operation of the external material plate 7; at the same time, the baffle 802 and the scraper 801 set at a 45-degree angle thereto form a waste glue channel 803, which can prevent the waste glue from entering the edge banding body 1 and affecting the normal operation of the equipment.

[0024] like Figure 1 As shown, one side of the second scraper 205 is in close contact with the outer side of the rubber guide roller 202 .

[0025] Specifically, through this arrangement, the second scraper 205 can slide to the bottom of the guide rail 204 when there is no need to scrape glue on the outer side of the glue guide roller 202, without affecting the normal use of the PUR edge banding machine.

[0026] like Figure 1 As shown, the glue coating roller 201 , the glue guiding roller 202 and the glue spraying head 203 are arranged horizontally with the rolling direction of the feeding roller 4 .

[0027] Specifically, by configuring the glue spray head 203 in this way, the glue can be gradually transferred from the hot melt glue tank 3 to the glue coating roller 201 . The horizontal arrangement can enable the glue to quickly contact the external material plate 7 , thereby completing the gluing operation.

[0028] like Figure 1 As shown, the output end of the glue spray head 203 is aligned with the outer side of the glue guide roller 202.

[0029] Specifically, this arrangement can prevent the glue spray head 203 from spraying glue onto other areas of the edge banding machine body 1, thereby avoiding affecting the normal operation of the PUR edge banding machine.
