Description

Technical Field

[0001] The utility model relates to the field of plate-type furniture processing equipment, in particular to a glue roller heating device for a glue cylinder of an edge banding machine and a glue cylinder of the edge banding machine. Background Art

[0002] Edge banding machine is a kind of woodworking machinery, belonging to the category of solid wood machinery, and is often used as professional edge banding equipment for woodworking boards such as furniture, cabinets, doors and windows. Its basic working principle is that the board goes through many processes such as conveying - pre-milling and trimming - gluing and pasting - front and back ends - upper and lower trimming - upper and lower fine trimming - upper and lower scraping - polishing, and finally the side of the board presents a beautiful, delicate, straight and smooth side edge. When the board is glued and pasted, the glue of EVA, PUR and other materials is heated and melted by the glue roller, and the edge banding tape and hot melt adhesive are attached to the side edge of the board by pressure wheel.

[0003] In the prior art, the edge banding machine uses a heating rod to heat the glue roller. Usually, the heating rod is fixed, a heat-conducting copper sleeve is arranged on the heating rod, and then a glue roller is arranged outside the heat-conducting copper sleeve. The glue roller is driven to rotate by a driving motor. During the operation of the glue roller of the edge banding machine glue cylinder, the glue roller rotates with the driving motor, while the heating rod and the heat-conducting copper sleeve do not rotate. The copper sleeve slides relative to the glue roller in the inner hole of the glue roller. After working for a long time, the heat-conducting copper sleeve will be deformed and stuck in the glue roller under the combined action of the heat generated by the heating rod and the friction heat with the glue roller, and even damage the heating rod. The deformed copper sleeve is difficult to remove from the glue, which affects the service life of the heating rod and reduces the processing accuracy, thereby affecting the normal operation of the edge banding machine. In addition, the existing edge banding machine glue cylinder usually controls the amount of glue by setting a photoelectric sensor on the outside of the glue pot to detect the external hot melt glue on the glue roller, but the photoelectric sensor often causes unstable feedback signals due to the surge of glue, resulting in glue leakage, which increases the production cost.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0027] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0028] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, a glue roller heating device for a glue cylinder of an edge banding machine includes a heating rod 1. One end of the heating rod 1 is sleeved with a needle bearing group. The needle bearing group includes a plurality of needle bearings 3 that are in end-to-end contact. The needle bearings 3 are rotatably connected to the heating rod 1. The material of the needle bearings 3 is a high-temperature resistant material. In this embodiment, the material of the needle bearings 3 is bearing steel. The glue roller 2 can be sleeved on one end of the heating rod provided with the needle bearing group, and the glue roller is driven to rotate by a driving motor.

[0030] Because a high-temperature resistant needle bearing 3 is arranged between the glue coating roller 4 and the heating rod 1, the possibility of deformation of the needle bearing 3 is reduced, and when the glue coating roller 2 rotates, the needle bearing 3 and the heating rod 1 are rotationally connected, which reduces damage to the heating rod 1 and extends the service life of the glue coating roller.

[0031] In order to reduce the damage to the inner hole surface of the glue coating roller 2 and the outer surface of the needle bearing 3 when the glue coating roller 2 rotates, so that the glue coating roller 2 and the drive motor shaft always remain on the same center line when rotating, the needle bearing 3 is rotatably connected to the glue coating roller 2. In this embodiment, the needle bearing 3 is Figure 3 K series needle roller bearings shown.

[0032] The driving motor is arranged at the end of the glue coating roller 2 which is not inserted into the heating rod, and the output shaft of the driving motor is fixedly connected to the end of the glue coating roller 2 which is not inserted into the heating rod.

[0033] A retaining ring 4 is provided at both ends of the needle roller bearing group 3. The retaining ring 4 is sleeved on the heating rod 1. The retaining ring 4 is made of a high temperature resistant material. In this embodiment, the retaining ring 4 is also made of bearing steel. The retaining ring 4 is provided to limit the installation position of the bearing 3, so that the rubber coating roller heating device can work more stably.

[0034] like Figure 4 As shown, this embodiment also provides a glue cylinder for edge banding machine, including the above-mentioned glue roller heating device for glue cylinder of edge banding machine. The glue cylinder of edge banding machine also includes a liquid level detection device 6 arranged in the glue cylinder 5, and the liquid level detection device 6 is electrically connected to the glue adding device, such as Figure 5As shown, the liquid level detection device 6 includes a liquid level sensor 61, a fixing frame 64 and a locking nut 62. The liquid level sensor 61 is arranged in the glue cavity of the glue cylinder 5, and the fixing frame 64 is arranged above the glue cavity. The liquid level sensor 61 is fixedly connected to the fixing frame 64 through the locking nut 62. The locking nut 62 is located between the fixing frame 64 and the glue cavity. A sealing ring 62 is arranged between the locking nut 62 and the glue cavity to prevent the glue in the glue cavity from overflowing.

[0035] The liquid level sensor 61 is used to detect the glue level in the glue cylinder 5. If the glue level drops below the set level, the liquid level detection device 6 sends a feedback signal to the glue adding device, and the glue adding device adds glue to the glue cylinder 5. To avoid glue leakage, the glue supply channel in the edge banding machine is sealed. The glue used in the edge banding machine in this embodiment is PUR glue.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
