Description

Technical Field

[0001] This utility model relates to the field of panel furniture machinery technology, and in particular to a glue pot device for an edge banding machine. Specifically, it is a compact, high-thermal-efficiency mini glue pot device. Background Technology

[0002] Edge banding machines are key pieces of equipment in panel furniture production lines, used to attach edge banding strips to the edges of the panels. The glue pot device is one of the core components of the edge banding machine; its function is to melt solid hot melt adhesive and apply the molten adhesive to the edge banding strip.

[0003] Currently, the glue pot devices commonly used in edge banding machines on the market typically have the following problems: 1. Large size and long preheating time: Traditional glue pots have a large capacity of glue chamber to store sufficient glue liquid, resulting in a bulky overall structure. When starting up for the first time or changing the type of glue, it takes a long time (usually more than 30 minutes) to heat the entire pot of solid glue to the working temperature, resulting in high energy consumption and low production efficiency.

[0004] 2. Significant heat loss and high energy consumption: Large plastic pots have a large surface area and dissipate heat quickly. In order to maintain the working temperature, the heating system needs to operate at high power continuously, resulting in energy waste.

[0005] 3. Slow response speed: Due to the large volume of adhesive, the temperature control system has a large inertia. When adjusting the working temperature, the system responds slowly, which is not conducive to achieving precise process control.

[0006] 4. Excessive adhesive residue and inconvenient cleaning when changing adhesives: Large glue pots have many dead corners and residual adhesives. When changing to different colors or types of hot melt adhesives, the cleaning work is cumbersome, which not only wastes adhesives but also increases downtime.

[0007] 5. Difficulty in adapting to miniaturization and modular design: As furniture production moves towards flexibility and customization, equipment requires a more compact layout. Traditional large glue pans take up a lot of space and are difficult to integrate into new, compact edge banding machines.

[0008] Therefore, there is an urgent need for a compact, fast-heating, energy-efficient, and easy-to-maintain glue pot device to overcome the above-mentioned defects of the existing technology. Utility Model Content

[0009] This utility model addresses the shortcomings of existing technologies by providing a mini glue pot device for edge banding machines. It features a compact structure, rapid heating, low energy consumption, and high thermal efficiency, making it particularly suitable for small edge banding machines or applications with strict space requirements.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a mini glue pot device for an edge banding machine, comprising: The pot body includes a molded seat with a material cavity, a scraper shaft rotatably disposed in the molded seat and located in the material cavity, and a glue gate adjusting component that drives the scraper shaft to rotate and scrape glue or guides the glue flowing out of the glue outlet of the molded seat. The adhesive application shaft is used to apply adhesive to the material. It includes an adhesive application shaft rotatably disposed in a U-shaped seat and a drive unit for driving the adhesive application shaft to rotate. The adhesive application shaft has a heating chamber, and the heating chamber extends through one end along the axial direction of the adhesive application shaft. The heating element section, used to heat the glue-coating shaft, includes a heating element inserted into the heating chamber; The upper cover is connected to one end of the U-shaped seat. It includes an adhesive guide block, which has a guide channel that communicates with the adhesive outlet. One end of the adhesive application shaft passes through the adhesive guide block. The end of the adhesive guide block connected to the heating tube is provided with a closed-loop block for sealing the heating chamber to prevent heat loss. The needle valve section is connected to an external glue feeding device and controls the flow of glue into the drainage channel. It includes a needle valve, the valve port of which is connected to the drainage channel.

[0011] Furthermore, a groove is provided on the inner wall of the U-shaped seat at the end away from the adhesive flow block. The groove is connected to the material cavity.

The semi-circular part contacts the inner wall of the material cavity, and the recessed scraper part contacts the glue application shaft.

[0013] Furthermore, the glue gate adjustment component includes a trapezoidal mounting base, a drive cylinder, a fisheye bearing, and a toggle component. One end of the toggle component is connected to the square end, and the other end is pivotally connected to the fisheye bearing. The drive cylinder is fixed on the trapezoidal mounting base, and its output end is connected to the fisheye bearing. The trapezoidal mounting base is fixed on the glue guide block. The toggle component includes a clamping part and a pivoting part. The clamping part is formed by two clamping plates, and when the two clamping plates are clamped, they form a square groove inside that matches the square end. The two clamping plates are provided with connecting holes, and the square end is locked by passing screws through the connecting holes of the two clamping plates.

[0014] Furthermore, a glue channel is formed outward from the glue outlet along the side wall of the material cavity. The depth of the glue channel gradually increases from the glue outlet end outward. When the drive cylinder drives the drive connection part to rotate the semi-circular part towards the material cavity to block the glue outlet, the glue flowing out of the glue outlet is guided to the coating shaft through the glue channel. When the drive cylinder drives the drive connection part to rotate the semi-circular part towards the coating shaft, the recessed scraper part approaches the coating shaft, so that the recessed scraper part scrapes the glue on the coating shaft.

[0023] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] like Figure 1 As shown, this embodiment provides a mini glue pot device for an edge banding machine. The mini glue pot device for an edge banding machine includes a pot body part 10, and a glue application shaft part 20, a heating tube part 30, a top cover part 40 and a needle valve part 50 respectively disposed on the pot body part 10.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the pot body 10 includes a U-shaped seat 101 with a material cavity 11. The U-shaped seat 101 has a glue outlet 102 communicating with the material cavity 11, and a glue channel 103 is formed along the side wall of the material cavity 11. The depth of the glue channel 103 gradually increases from the end of the glue outlet 102 outwards. The U-shaped seat 101 has first and second mounting holes arranged vertically on both sides. Bearings are provided in the first and second mounting holes on both sides. A scraper shaft 104 connected to the bearing is installed in the first mounting hole. The scraper shaft 104 is located inside the material cavity 11, and a drive scraper shaft 104 is provided on the upper cover 40. The 04 rotating glue gate adjusting component 105 drives the scraper shaft 104 to rotate, so that one end of the scraper shaft 104 blocks the glue outlet 102, allowing the glue to flow through the glue channel 103 to the coating shaft section 20. The glue gate adjusting component 105 drives the scraper shaft 104 to rotate, so that the other end of the scraper shaft 104 scrapes and pushes the glue onto the coating shaft section 20, so that the glue is evenly coated on the coating shaft section 20, ensuring that the glue thickness on the coating shaft section 20 is consistent. The glue thickness on the coating shaft section 20 can be adjusted by adjusting the distance between the scraper shaft 104 and the coating shaft section 20.

[0026] The adhesive application shaft section 20 is used to apply adhesive to the material. The adhesive application shaft section 20 includes an adhesive application shaft 201 mounted on the second mounting hole and a drive unit (not shown in the figure) that drives the adhesive application shaft 201 to rotate. The drive unit (not shown in the figure) drives the adhesive application shaft 201 to rotate, which, in conjunction with the scraper shaft 104, allows the adhesive to be evenly applied to the adhesive application shaft 201. The adhesive application shaft 201 has a heating chamber that mates with the heating tube section 30, and the heating chamber extends through one end along the axial direction of the adhesive application shaft 201, so that the heating tube section 30 can extend into the heating chamber for heating.

[0027] The heating element portion 30 is used to heat the adhesive application shaft 201. This heating element portion 30 includes a heating element 301 inserted into the heating chamber, and the heating element 301 is fixedly connected to the upper cover portion 40. The upper cover portion 40 includes an adhesive drainage block 401, which is fixed to one end of the U-shaped seat 101. The adhesive drainage block 401 has a drainage channel communicating with the adhesive outlet 102. One end of the adhesive application shaft 201 passes through the adhesive drainage block 401, allowing the adhesive to drain... The connection end between block 401 and heating tube 301 is provided with a closed-loop block 402 for sealing the heating chamber to prevent heat loss; the rubber material drainage block 401 is provided with a sealing groove 403 for installing the closed-loop block 402. The sealing groove 403 is inlaid with a high-temperature resistant sealing ring that contacts the bottom surface of the closed-loop block 402. The closed-loop block 402 is tightly fitted with the sealing groove 403 through the high-temperature resistant sealing ring, which effectively blocks the air convection between the heating chamber and the outside, thereby reducing heat loss and improving heating efficiency.

[0028] The needle valve part 50 is connected to an external glue feeding device and is used to control the flow of glue into the diversion channel. The needle valve part 50 includes a needle valve installed on the glue diversion block 401, and the valve port of the needle valve is connected to the diversion channel. By controlling the opening or closing of the needle valve, the flow of glue is controlled, so that the glue flows into the material chamber 11 through the diversion channel, or flows to the glue coating shaft 201 through the glue channel 103.

[0029] In order for the scraper shaft 104 to block the glue outlet 102 and allow the glue to flow through the glue channel 103 onto the coating shaft 201, or to apply the glue to the coating shaft 201, such as... Figure 5 As shown, in this embodiment, the scraper shaft 104 has a semi-circular portion 1040, a recessed scraper portion 1041, and a drive connection portion 1042. The end of the drive connection portion 1042 is provided with a square end 1043 connected to the glue gate adjustment component 105. The recessed scraper portion 1041 is located on the back of the semi-circular portion 1040. The semi-circular portion 1040 contacts the inner wall of the material cavity 11, and the recessed scraper portion 1041 contacts the glue application shaft 201. When the glue gate adjustment component 105 drives the drive connection portion 1042, it causes the semi-circular portion 1040 to rotate toward the material cavity 11, blocking the glue outlet 10. At time 2, the adhesive flowing out through the glue outlet 102 is guided to the coating shaft 201 through the glue channel 103; when the drive cylinder 1051 drives the drive connection part 1042 to rotate the semi-circular part 1040 toward the coating shaft 201, the recessed scraper part 1041 approaches the coating shaft 201, so that the recessed scraper part 1041 scrapes the adhesive on the coating shaft 201. The angle of rotation of the recessed scraper part 1041 is driven by the glue gate adjustment component 105 to adjust the distance between the recessed scraper part 1041 and the coating shaft 201, so as to adjust the thickness of the adhesive on the surface of the coating shaft 201.

[0030] like Figure 6As shown, the glue gate adjustment component 105 includes a trapezoidal mounting base 1050, a drive cylinder 1051, a fisheye bearing 1052, and a toggle member 1053. One end of the toggle member 1053 is connected to the square end 1043, and the other end is pivotally connected to the fisheye bearing 1052. The drive cylinder 1051 is fixed on the trapezoidal mounting base 1050, and its output end is connected to the fisheye bearing 1052. The trapezoidal mounting base 1050 is fixed on the glue material guide block 401. The toggle member 1053 includes a clamping part 10530 and a pivoting part 10531. The clamping part 10530 is formed by two clamping plates, and when the two clamping plates are clamped, they form a square groove inside that matches the square end 1043. The two clamping plates are provided with The connecting hole is used to lock the square end 1043 by passing screws through the connecting holes of the two clamping plates; the pivot part 10531 is located on one side of the clamping part 10530 and is pivotally connected to the fisheye bearing 1052; when the drive cylinder 1051 is started, its output end drives the fisheye bearing 1052 to move, and the fisheye bearing 1052 in turn drives the toggle member 1053 to move. Since one end of the toggle member 1053 is connected to the square end 1043, it will drive the drive connecting part 1042 of the scraper shaft 104 to move, thereby realizing the rotation of the semicircular part 1040 of the scraper shaft 104 or the coating shaft 201, so as to control the flow direction of the adhesive and adjust the thickness of the adhesive on the surface of the coating shaft 201.

[0031] In this embodiment, the U-shaped base 101 is provided with a photoelectric sensor 106 for sensing whether there is adhesive on the coating shaft 201, and the side wall of the U-shaped base 101 is provided with an inclined groove 107 for the light source of the photoelectric sensor 106 to pass through to detect whether there is adhesive on the coating shaft 201. When the photoelectric sensor 106 senses that there is adhesive on the coating shaft 201, the photoelectric sensor 106 feeds back the signal to the drive unit (not shown in the figure), so that the drive unit (not shown in the figure) drives the coating shaft 201 to rotate, so that the coating shaft 201 coats the material with adhesive.

[0032] In an optional embodiment, a groove 108 is provided on the inner side wall of the U-shaped seat 101 at the end away from the adhesive guide block 401. The groove 108 communicates with the material cavity 11. An adhesive outlet 109 is provided on the side wall of the groove 108. A guide plate 110 is provided at the lower end of the U-shaped seat 101 at the adhesive outlet 109. The guide plate 110 is inclined. The adhesive in the material cavity 11 and the adhesive application shaft 201 flows into the groove 108. The adhesive in the groove 108 flows out through the adhesive outlet 109 and is guided to a set position by the guide plate 110. The guide plate 110 is provided to prevent the adhesive from flowing out from the side wall of the U-shaped seat 101 and to prevent it from affecting the drive unit (not shown in the figure) driving the adhesive application shaft 201.

[0033] In summary, the mini glue pot device of this edge banding machine has a compact structure and high space utilization. The glue application shaft part 20, heating tube part 30, upper cover part 40 and needle valve part 50 are set on the U-shaped seat 101 of the pot body part 10, which makes it occupy little space and easy to integrate into various edge banding equipment. It is especially suitable for multi-sided edge banding machines and production line layouts with limited space.

[0034] The technical features of the above embodiments can be combined in any way.
