Description

Technical Field

[0001] The invention relates to the technical field of thermal drying of edge banding strips, and in particular to a multi-level thermal drying process for edge banding strips. Background Art

[0002] The main component of edge banding is polyvinyl chloride, which is manufactured through mixing, calendering water spraying, vacuum forming and other processes. The main function of edge banding is to seal the cross-section of the board to protect it from adverse factors in the environment and during use, such as moisture and friction, and to prevent the volatilization of formaldehyde inside the board, while achieving a decorative and beautiful effect.

[0003] After the edge strips are calendered and sprayed with water, a thermal drying process is required to remove water stains on the surface of the edge strips. Most of the thermal drying processes in the prior art heat the air through a dryer, so that the hot air evaporates the water stains on the surface of the edge strips, thereby achieving thermal drying. For example, a quick-drying device for edge strip printing equipment with Chinese patent publication number CN220500274U includes a frame, a conveying member arranged on the frame, and a cover arranged on the frame. The side walls of the cover on opposite sides are respectively provided with through openings. The conveying path of the conveying member is located between the cover and the frame and passes through the two through openings. A drying member is arranged in the cover, and the drying member is used to dry the edge strips placed on the conveying member. This solution adds a fan to blow out the hot air, which speeds up the evaporation rate of water stains and can quickly cool down the edge strips.

[0004] And compared with a device for drying edge banding strips with Chinese patent publication number CN111121329B, it includes a dewatering mechanism A and a dewatering mechanism B distributed on the upper and lower sides of the support frame, and both the dewatering mechanism A and the dewatering mechanism B dewater the edge banding strips. This solution improves the drying effect by adding a sponge belt to absorb water stains on the surface of the edge banding strip, and can also clean impurities and dust attached to the surface of the edge banding strip at the same time.

[0005] The above solutions all blow hot air to the sealing strip to blow away and evaporate the water stains. However, the water will splash into the heat drying equipment along with the airflow during the blowing and evaporation process, and may even be blown back onto other parts of the edge strip surface. Most existing edge strip heat drying processes are not convenient for preventing water from splashing around, which can easily reduce the heat drying effect and even cause the heat drying equipment to be damaged by moisture.

At the same time, when the edge banding strip body is located in the empty groove, the inclined structure at one end of the baffle can scrape the moisture on its surface to both sides, further improving the drying effect.

[0022] 4. When the edge band contacts the sponge roller and lifts it upward, the sealing plate is inserted into the slot through the transmission of the second linkage assembly to block the pipeline to seal it, thereby ensuring the sealing inside the collection box, thereby improving the suction provided by the hollow cylinder when the fan is working and further improving the drying effect.

[0048] like Figures 1 to 13 As shown:

[0049] The multi-level heat drying process for edge banding includes the following steps: placing the edge banding body 14 on the operating table 13 and inserting the bottom of the friction wheel 62; the heat drying component 2 installed on the frame 1 is used to dry the edge banding body 14 and extract the hot air with moisture to prevent water stains from splashing; the conveying components 6 installed at both ends of the frame 1 can make the edge banding body 14 move horizontally with the rotation of the friction wheel 62, fix and convey the edge banding body 14; the first linkage component 4 is installed on one side of the frame 1, which can drive the conveying component 6 and the heat drying component 2 to work at the same time; the collecting component 3 installed on the frame 1 is used to collect moisture and dust into the collecting box 30; the second linkage component 5 is installed on the other side of the frame 1, which can ensure the airtightness of the collecting box 30 when the heat drying component 2 is working, thereby improving the drying effect.

[0050] The frame 1 includes a base 10, a partition 11, a plurality of enclosures 12 and an operating table 13. The base 10 is a frame structure. The top of the base 10 is fixedly connected to the bottom of the operating table 13. The top of the operating table 13 is fitted with the bottom of the edge strip body 14. The outer periphery of the partition 11 is fixedly connected to the inner wall of the base 10. The plurality of enclosures 12 are respectively installed on the outer periphery of the base 10. The frame 1 is used to support the edge strip body 14 and the heat drying component 2 for easy operation by the staff. The heat drying component 2 includes a drying chamber 20, a pair of heating lamps 21, a hollow cylinder 22, a sponge roller 23, a spring 24, a hose 25 and a fan 26. The bottom of the drying chamber 20 is fixedly connected to the top of the base 10. An empty slot 200 is opened at the bottom of the drying chamber 20. The operating table 13 passes through the empty slot 200. When the edge strip body 14 moves past the top of the operating table 13, it will enter the drying chamber 20 through the empty slot 200 and then leave from the other end of the empty slot 200. Two heating lamps 21 are symmetrically distributed on both sides of the drying chamber 20. The top of the heating lamp 21 is fixedly connected to the top wall of the drying chamber 20. When the heating lamp 21 is powered on, it emits heat to heat the air and irradiates the surface of the edge strip body 14, so that the moisture on its surface can be evaporated. The hollow cylinder 22 can be installed in the drying chamber 20 in a vertically movable manner. The two sides of the hollow cylinder 22 are respectively rotatably connected to the inner walls of the two sides of the heating chamber. One side of the hollow cylinder 22 passes through the inner wall of one side of the heating chamber and is connected to one end of the hose 25. The sponge roller 23 is sleeved on the outer periphery of the hollow cylinder 22. The sponge roller 23 and the outer periphery of the hollow cylinder 22 are both provided with a plurality of air holes 220 and are connected to each other. The spring 24 is installed on the drying chamber 20. The spring 24 is used to provide vertical downward pressure to the hollow cylinder 22. When the edge strip body 14 passes through the empty groove 200, the sponge roller 23 squeezes the edge strip body 14 downward, thereby absorbing the water stains on its surface, and can also absorb dust and foreign matter on the surface of the edge strip body 14. The first linkage assembly 4 is used to drive the sponge roller 23 and the friction wheel 62 to rotate in the opposite direction, so that the rotation direction of the sponge roller 23 is opposite to the moving direction of the edge banding strip body 14, which can further improve the water absorption of the sponge roller 23 and the effect of cleaning dust. The collecting assembly 3 includes a collecting box 30, the bottom of the collecting box 30 is fixedly connected to the top of the partition 11, the air inlet of the fan 26 is connected to one end of the collecting box 30, the air outlet of the fan 26 extends to the outside of the frame 1, and the other end of the hose 25 is connected to one side of the collecting box 30. The fan 26 is powered on to work, and the air inside the collecting box 30 is extracted to form a negative pressure, so that the hot air inside the drying chamber 20 flows into the hollow cylinder 22 through the air hole 220 and is discharged from the drying chamber 20 through the hose 25. At the same time, the airflow can take away the remaining moisture and dust on the surface of the edge banding strip body 14 to prevent water stains from splashing, and the sponge roller 23 can also be dried by the heating lamp 21 and the airflow, saving the step of drying the sponge roller 23 in the gap of drying the edge banding strip body 14, which can further improve the thermal drying efficiency.

[0051] like Figures 1 to 9As shown:

[0052] The heat drying assembly 2 also includes a pair of baffles 27, which are respectively located at the two ends of the empty slot 200 and are respectively hinged to the two ends of the drying chamber 20. A pair of limit blocks 28 are symmetrically installed at the bottom of one end of the baffle 27, and the other end of the baffle 27 is a slope structure. By setting the baffle 27, the sealing of the drying chamber 20 can be ensured during the heat drying process, heat loss can be avoided, and energy consumption can be reduced. When the edge strip body 14 is separated from the empty slot 200, the baffle 27 is in a vertical state, and one side of the limit block 28 is in contact with the drying chamber 20; at this time, the baffle 27 blocks the two ends of the empty slot 200 to prevent heat loss. When the edge strip body 14 is located in the empty slot 200, the baffle 27 is in an inclined state, and the slope at one end of the baffle 27 is in contact with the top of the edge strip body 14. At this time, the bottom of the baffle 27 keeps rotating toward the bottom driven by the gravity of the limit block 28, thereby pressing down the edge banding strip body 14. The inclined structure at one end of the baffle 27 can scrape the moisture on its surface to both sides, further improving the drying effect.

[0053] like Figures 1 to 12 As shown:

[0054] The collection assembly 3 also includes a pair of collection boxes 31 and pipes 32. The top of the collection box 31 is fixedly connected to the top wall of the frame 1. Water tanks 100 are symmetrically provided on both sides of the top of the base 10. The water tanks 100 are connected to the top of the collection box 31. The bottom wall of the collection box 31 is an inclined structure. One end of the collection box 31 is connected to the pipe 32, and one side of the pipe 32 is connected to the top of the collection box 30. When the excess water is scraped off by the baffle 27 and flows down the operating table 13, it will enter the collection box 31 through the water tank 100 and flow into the water pipe, and finally enter the collection box 30 to complete the collection, so as to prevent the water from contacting the edge strip body 14 again.

[0055] like Figures 1 to 13 As shown:

[0056] The second linkage assembly 5 includes a pair of connecting rods 50, a pair of racks 51, a first gear 52 and a sealing plate 53.

The ends of the two racks 51 that are away from each other are fixedly connected to the two connecting rods 50 respectively. The connecting rods 50 can be installed on the frame 1 in a vertically slidable manner. The bottom of one of the connecting rods 50 is fixedly connected to the sealing plate 53. A slot 320 is provided at the top of the pipe 32. The slot 320 is plugged into the sealing plate 53. The top of the other connecting rod 50 is fixedly connected to the periphery of one end of the hollow cylinder 22 close to the hose 25. When the edge sealing strip slowly enters the empty groove 200, it first contacts the baffle 27. At this time, the baffle 27 scrapes off the water stains on its surface and flows into the collection box 30 through the pipe 32. When the edge sealing strip contacts the sponge roller 23 and lifts it upward, one of the connecting rods 50 follows the hollow cylinder 22 to move upward, and at the same time drives one of the racks 51 to move. Through the meshing transmission of the rack 51 and the first gear 52, the first gear 52 rotates, and the other rack 51 moves downward, thereby pushing the other connecting rod 50 to move downward and insert the sealing plate 53 into the slot 320, blocking the pipe 32 to seal it, and the moisture remains in the pipe 32 to ensure the sealing of the collection box 30, thereby improving the suction provided by the hollow cylinder 22 when the fan 26 is working, further improving the drying effect.

[0057] like Figures 1 to 11 As shown:

[0058] The other side of the hollow cylinder 22 passes through the inner wall of the other side of the drying chamber 20 and is slidably connected thereto, so that the hollow cylinder 22 can stably move up and down while rotating. The hot drying assembly 2 also includes a slider 29, which is rotatably connected to the outer periphery of one end of the hollow cylinder 22 away from the hose 25, one end of the spring 24 is fixedly connected to the top of the slider 29, and the other end of the spring 24 is fixedly connected to the raised bottom of the side wall of the drying chamber 20. When the hollow cylinder 22 moves upward, the slider 29 presses the spring 24 upward, and the spring 24 contracts and keeps a tendency to rebound to the bottom, thereby providing downward pressure on the slider 29 and the hollow cylinder 22.

The bottoms of the two friction wheels 62 respectively conflict with the two sides of the top of the edge banding strip body 14. Insert the edge banding strip body 14 into the bottom of the friction wheel 62, the edge banding strip body 14 pushes the friction wheel 62 upward, the round rod 61 is lifted, the hydraulic rod 64 is extended, and then the hydraulic rod 64 is operated, and its telescopic end moves downward, driving the fixed block 63 to move, so that the edge banding strip body 14 is squeezed by the friction wheel 62 to be fixed on the top of the operating table 13, and then the friction wheel 62 is rotated, and the friction force pushes the edge banding strip body 14 to move on the top of the operating table 13, so as to realize the transportation of the edge banding strip body 14.
