Description

Technical Field

[0001] The utility model belongs to the technical field of edge banding machines, and particularly relates to a PUR edge banding cooling device. Background Art

[0002] In the board edge banding process, with the diversification of product processing, PUR edge banding technology is becoming more and more popular in the furniture industry. Currently, there are three mainstream edge banding processes, namely EVA edge banding, PUR edge banding, and laser edge banding. The glue line of PUR edge banding is thinner, second only to laser edge banding. PUR edge banding is more reliable because the curing of PUR glue is moisture curing and needs to react with moisture in the air to achieve chemical reaction-type edge banding bonding. In actual production, in order to obtain better edge banding effect, PUR glue needs to be cooled quickly. However, after the existing board is edge banded by the PUR edge banding machine, the PUR glue at the edge of the board is cooled by an air blower. It is a single-sided jet cooling structure, and the cooling speed of PUR glue is low, which reduces the bonding stability of PUR glue to the board and edge banding.

[0003] At present, the utility model with the publication number CN219337993U proposes a PUR edge banding automatic cooling device for edge banding process, which solves the problem of rapid automatic cooling of PUR glue, improves the stability of processing PUR edge banding, provides guarantee for the subsequent edge banding trimming of the board, ensures processing stability, is conducive to rapid cooling of glue, ensures the adhesion of the edge band, and makes the post-process tool and board surface cleaner and easy to remove debris. However, the above-mentioned prior art still has the following deficiencies when used: 1. During the blowing process of the upper and lower air pipes, the discrete glue containing debris and dust will adhere to the upper and lower air pipes, and even be adsorbed at the air outlet of the upper and lower air pipes, thereby reducing the air outlet and affecting the cooling effect; 2. The distance between the upper and lower air pipes of the above-mentioned prior art is difficult to adjust, that is, it does not have the function of adjusting the blowing force, and it is difficult to blow away the debris adhered to the process tool and the board surface, affecting the quality of the subsequent edge banding of the edge banding machine.

DETAILED DESCRIPTION

[0025] The utility model will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0026] As attached Figure 1-4As shown, the utility model includes an air blowing pipe 1 and a diverter pipe 2, and also includes a seat plate 3. When in use, the seat plate 3 replaces the right-angle fixed bracket in the patent document mentioned in the background technology to be connected to the PUR edge banding machine body. The function of the diverter pipe 2 is the same as the air duct device in the patent document mentioned in the background technology, both of which play the role of diverting cold air. When in use, the air inlet pipe on the diverter pipe 2 is connected to the external cold air connecting pipe.

[0027] A rolling groove 31 is provided on one side of the seat plate 3, and the rolling groove 31 is a T-shaped groove. A connecting plate 21 is provided in the middle of one side of the shunt pipe 2. The connecting plate 21 and the upper and lower sides of the rolling groove 31 are in damping rolling cooperation. Specifically, two rollers 7 are provided on one side of the connecting plate 21, which are close to the upper and lower end faces respectively. The upper and lower side walls of the rolling groove 31 are both bonded with a resistance-increasing tape 8, one side of which is against the outer peripheral wall of the roller 7. When the connecting plate 21 moves along the rolling groove 31, the roller 7 will roll the resistance-increasing tape 8. Under the elastic extrusion of the resistance-increasing tape 8, the connecting plate 21 can stay at a fixed point. One side of the resistance-increasing tape 8 is provided with grooves 81 evenly distributed along the length direction, and the grooves 81 can further increase the rolling resistance of the roller 7.

[0028] A screw rod 4 is rotatably connected to the other side of the diverter pipe 2, and a symmetrically distributed upper suspension rod 5 and a lower suspension rod 6 are screwed on the screw rod 4. The upper suspension rod 5 and the lower suspension rod 6 are parallel and connected to the diverter pipe 2 for sliding up and down connection. The free ends of the upper suspension rod 5 and the lower suspension rod 6 are fixedly connected to the blowing pipe 1 opposite to the air outlet. Firstly, when the diverter pipe 2 slides along the rolling groove 31, the position of the air jet from the blowing pipe 1 can be adjusted, and the blowing pipe 1 can also be transferred to a large area of ​​the external space. Secondly, when the screw rod 4 rotates, the distance between the upper suspension rod 5 and the lower suspension rod 6 on the blowing pipe 1 can be adjusted, thereby adjusting the blowing force of the blowing pipe 1 on the tool and the panel.

[0029] The other side of the shunt pipe 2 is fixedly connected with a hanging plate 23, the free end of the hanging plate 23 is fixedly connected with a positioning sleeve 231 that is rotatably connected to the middle of the screw rod 4, and the other ends of the upper hanging rod 5 and the lower hanging rod 6 are respectively fixedly connected with an upper thread sleeve 51 and a lower thread sleeve 61, which are screwed together with the screw rod 4, wherein the threads in the upper thread sleeve 51 and the lower thread sleeve 61 are in opposite directions, thereby controlling the rotation of the screw rod 4, so that the upper hanging rod 5 and the lower hanging rod 6 can move synchronously in opposite directions. The outer peripheral wall of the positioning sleeve 231 is fixedly connected with a pull rod 2312, and the function of the pull rod 2312 is to facilitate manual holding and pulling of the connecting plate 21 to move relative to the seat plate 3.

[0030] A support plate 2311 is fixedly connected to one side of the positioning sleeve 231, and a vertically distributed guide shaft 23111 is fixedly provided at the free end of the support plate 2311. The guide shaft 23111 is in vertical rolling cooperation with the upper hanging rod 5 and the lower hanging rod 6. Specifically, a guide hole 9 with a clearance fit with the guide shaft 23111 can be opened on the upper hanging rod 5 and the lower hanging rod 6, and then a circumferentially evenly distributed ball 91 is embedded in the guide hole 9, and the outer spherical wall of the ball 91 is against the outer circumferential wall of the guide shaft 23111. This cooperation method can effectively avoid the problem of movement jamming of the upper hanging rod 5 and the lower hanging rod 6.

[0031] The upper and lower ends of the shunt pipe 2 are fixedly connected with joints 22, which are connected to one end of the blowing pipe 1 through a hose. The cold air entering the shunt pipe 2 is diverted by the joints 22 at the upper and lower ends and then supplied to the blowing pipe 1.

[0032] One end of the rolling groove 31 extends to one end of the seat plate 3, and a mounting hole 32 close to the non-open end of the rolling groove 31 is opened on one side of the seat plate 3. The seat plate 3 is installed on the frame near the edge banding area of ​​the PUR edge banding machine body through the mounting hole 32 using bolts. Since one end of the rolling groove 31 is open, this arrangement makes it convenient to roll the connecting plate 21 directly out of the rolling groove 31, making it convenient to perform offline maintenance on the blowing pipe 1 and the diversion pipe 2.

[0033] The upper and lower ends of the screw rod 4 are fixedly connected with a screw disk 41 , which is a hand-held component for facilitating manual control of the rotation of the screw rod 4 .

[0034] Operation method: (1) When the blowing position of the air blowing tube 1 needs to be adjusted, manually push the pull rod 2312, and the roller 7 rolls along the resistance increasing tape 8. When the blowing position of the air blowing tube 1 is adjusted, stop pushing the connecting plate 21. At this time, under the restriction of the groove 81 and the elastic thrust of the resistance increasing tape 8, the roller 7 will not rotate freely, and the position of the air blowing tube 1 is still fixed. (2) When the air blowing tube 1 needs to be cleaned, manually pull the connecting plate 21 outward. At this time, the entire shunt tube 2 moves outward along the rolling groove 31 until it leaves the groove 81. At this time, the adhesion adsorbed on the outside of the shunt tube 2 and the air blowing tube 1 can be cleaned. (3) When it is necessary to increase the blowing force of the air blow pipe 1 to clean the debris adhered to the tool and the panel, the screw 4 is manually controlled to rotate by turning the dial 41, and the upper suspension rod 5 and the lower suspension rod 6 will be close to each other under the spiral transmission, thereby shortening the distance between the air outlet of the air blow pipe 1 and the tool and the panel, thereby increasing the blowing force and effectively blowing away the adhesions on the tool and the panel.

Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the scope and spirit of the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the intent of the present invention also includes these modifications and variations.
