Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically, to a device for precise cutting and joining of edge banding tape for sheet metal. Background Technology

[0002] In the manufacturing process of wooden furniture, edge banding is usually applied to the cut surfaces of the boards to enhance their protection and aesthetics. Edge banding not only effectively seals the board surfaces, preventing damage from external factors such as moisture and humidity, but also effectively blocks the volatilization of harmful substances like formaldehyde from within the board, thus ensuring the furniture's environmental friendliness and safety.

[0003] Currently, edge banding machines are widely used for automated edge banding in the edge banding process of wooden furniture. The emergence of edge banding machines has greatly improved edge banding efficiency and ensured edge banding quality.

[0004] Chinese patent CN110774405A discloses a precision cutting edge banding machine for sheet metal. The applicant utilizes an edge banding identification sensor to detect the position of the edge banding break. However, in practical application, the applicant found that using a laser displacement sensor as the edge banding identification sensor is relatively expensive, increasing the manufacturing and operating costs of the edge banding machine. More importantly, when the sheet metal edge has defects such as burrs or unevenness, the laser displacement sensor is prone to false triggering due to these minor disturbances, leading to inaccurate edge banding cutting positions. This false triggering phenomenon occurs frequently in actual use, affecting the stability and reliability of the edge banding machine. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0031] like Figures 1-10 As shown, a precision cutting and joining device for edge banding of sheet metal includes a support base 4, on which a rotating frame 5 is rotatably connected. A trigger sensor 56 is mounted on the rotating frame. The trigger sensor, under the action of a torsion spring 215, abuts against the side wall of the support base. The trigger sensor 56 can detect whether the trigger sensor is abutting against the side wall of the support base 4. When the sheet metal is placed on the support base, the edge banding of the sheet metal contacts the rotating frame, causing the rotating frame to rotate. This disengages the contact switch from the side wall of the support base, thereby triggering the position at the break point of the edge banding. The trigger sensor can include various types of sensors available in the prior art, such as microswitch sensors, pressure sensors, photoelectric sensors, infrared sensors, ultrasonic sensors, capacitive sensors, magnetic sensors, limit switches, proximity switches, magnetic switches, etc. The sensor can be used to detect whether the trigger sensor is abutting against the side wall of the support base. These sensors can be purchased externally; for example, a small microswitch such as the KW12-2Z-0105SF2 from Qiaoheng can be used.

[0032] In at least one embodiment, a base plate 1 is further included, on which a first guide rod 21 and a second guide rod 22 are provided. A support seat 4 is slidably fitted on the first guide rod and the second guide rod. An adjustment limiting plate 3 is provided on the top of the first guide rod and the second guide rod. A floating adjustment component is provided on the second guide rod, and a rotation adjustment component is provided on the first guide rod.

[0033] In at least one embodiment, the floating adjustment component includes an adjustment wheel 42, a flexible spring 43, a limiting bolt 44, and a lower sleeve 41. The top of the adjustment limiting plate is provided with a left mounting hole 31 and a right rectangular groove 32. The right rectangular groove is provided with a positioning hole 321 and a right mounting hole 322. The first bolt 71 passes through the left mounting hole and is threaded into the threaded hole at the top of the first guide rod. The second bolt 72 passes through the right mounting hole and the adjustment wheel in sequence and is threaded into the threaded hole at the top of the second guide rod. The middle of the adjustment wheel is provided with a central mounting hole 421 to accommodate the passage of the second bolt. Limiting mounting holes 422 are provided on both sides of the central mounting hole. The limiting bolt 44 can pass through the positioning hole and the limiting mounting hole in sequence to restrict the adjustment wheel from rotating around the second bolt. A flexible spring is installed between the adjustment wheel and the lower sleeve.

[0034] Furthermore, the bottom of the adjusting wheel has an inner thread groove that cooperates with the flexible spring. Rotation of the adjusting wheel allows the flexible spring to be inserted into or separated from the inner thread sleeve. The more the flexible spring is inserted into the inner thread sleeve, the further the support is from the base plate, thus achieving vertical floating distance adjustment between the base plate and the support.

[0035] In at least one embodiment, the support includes a lifting plate with a left lifting hole 402 and a right lifting hole. An extended linear bearing 211 is installed in the left lifting hole and cooperates with a first guide rod. A right linear bearing 221 is installed in the right lifting hole and cooperates with a second guide rod. A lower sleeve is provided at the top of the right lifting hole. The lifting plate is connected to a horizontal plate 403, and a support platform 404 for supporting the plate is formed at the end of the horizontal plate.

[0036] Furthermore, a stop 405 is formed between the horizontal plate and the lifting plate. The stop can prevent the plate from contacting the rotating frame when it rotates, thus preventing the sensor from being accidentally triggered.

[0037] In at least one embodiment, the rotation adjustment component includes a torsion spring 215, a torsion spring locking sleeve 214 is provided at the top of the first guide rod, a rotating sleeve 212 is provided on the outer side of the extended linear bearing, a torsion spring is sleeved on the rotating sleeve, a height adjustment ring 213 is threadedly connected to the rotating sleeve, a rotating frame is threadedly connected to the rotating sleeve, the rotating frame is located directly above the height adjustment ring, one end of the torsion spring is fixedly connected to the torsion spring locking sleeve, and the other end is fixedly connected to the rotating frame.

[0038] In a more detailed design, the height adjustment ring can rotate to move the rotating frame closer to or further away from the support.

[0039] In at least one embodiment, the rotating frame includes a rotating plate 51, an insertion hole 52 that mates with the rotating sleeve is formed in the middle of the rotating plate, a lower vertical plate 53 is provided at the bottom of the rotating plate, a triangular baffle 55 is connected to the lower vertical plate, and a positioning mounting hole 551 for mounting a trigger sensor is formed on the triangular baffle.

[0040] In at least one embodiment, a rectangular elongated hole 101 is formed on one side of the base plate, a guide shaft 61 is inserted into the rectangular elongated hole, the lower end of the guide shaft can be fixedly connected to the edge banding machine table, and a plurality of guide wheels 62 are rotatably connected to the guide shaft.

[0041] Furthermore, the base plate is provided with a locking bolt 102, the end of which can be inserted into a rectangular elongated hole and abut against the surface of the guide wheel.

[0042] In operation, the device is installed on the edge banding machine table. The floating distance between the support 4 and the base plate 1 is adjusted according to the thickness of the board and the edge banding requirements. The height of the support is adjusted by rotating the adjusting wheel 42, causing the flexible spring 43 to engage or disengage from the inner thread groove. The height of the rotating frame 5 is adjusted by rotating the height adjusting ring, moving the frame closer to or further away from the support to ensure the edge banding tape accurately triggers the trigger sensor 56. The board is placed on the support table 404, and its long side moves forward along the guide wheel 62. Under the weight of the board, the support 4 moves vertically downward along the first guide rod 21 and the second guide rod 22, stretching the flexible spring 43. When the edge banding tape end of the board contacts the triangular baffle 55, the rotating frame 5 rotates around the first guide rod. The trigger sensor 56 on the rotating frame disengages from the side wall of the support, triggering a signal to achieve precise cutting of the edge banding tape.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
