Description

Technical Field

[0001] This utility model relates to the technical field of edge banding equipment for sheet metal, specifically to a telescopic adjustment device for a blade trimming and a trimming assembly. Background Technology

[0002] In the furniture industry, to prevent boards from warping due to moisture, to improve their appearance, or to prevent edge cracking, edge banding is usually applied to the edges of the boards after processing. After edge banding is completed on one side of the board, there will be excess material at the beginning and end of the sealing strip. This excess material is usually trimmed using a trimming device.

[0003] In existing technologies, the edge-banding saw blade assembly in edge-banding devices is fixed (e.g., the patent "An Edge-Banding Edge-Banding Device" disclosed in patent publication number CN217072599U), and the saw blade in the edge-banding saw blade assembly cannot be adjusted for forward or backward extension. With the development trend of furniture products, the applicant discovered that to improve the appearance of the edge-banded product, a certain length of the sealing strip can be reserved during the cutting of the sealing strip on the board (i.e., not cut cleanly) for the tracking device on the edge-banding machine to perform chamfering. However, because the edge-banding saw blade assembly in the existing edge-banding machine's edge-banding device is fixed, the cutting position of the saw blade cannot be adjusted. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of this utility model is to provide a telescopic adjustment device and a cutting assembly for a saw blade, so as to solve the problem that the cutting position of the saw blade cannot be adjusted by moving it forward and backward because the cutting blade assembly of the existing cutting device is fixed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] In a first aspect, this application provides a telescopic adjustment device for a paring saw blade, including a paring saw blade, a motor, and a template. The motor is connected to the paring saw blade, and the device also includes a cylinder, a cylinder mounting base, and a connecting arm. The cylinder is fixedly mounted on the cylinder mounting base, and the motor is slidably mounted on the cylinder mounting base. The motor and the cylinder mounting base form an axial sliding connection parallel to the output shaft of the motor. One end of the connecting arm is fixedly connected to the cylinder, and the other end of the connecting arm is fixedly connected to the motor. The template is mounted on the outer side of the cylinder mounting base near one end of the paring saw blade.

[0007] Furthermore, it also includes an infeed limit screw and an outfeed limit screw. The infeed limit screw is fixedly installed on the connecting arm, with one end of the infeed limit screw extending horizontally toward one side of the cylinder. The outfeed limit screw is fixedly installed on the connecting arm, with one end of the outfeed limit screw extending horizontally toward the other side away from the cylinder.

[0008] Furthermore, it also includes a template adjusting seat and an adjusting screw. The template adjusting seat is fixedly installed on the outer side of the cylinder mounting seat. A nut is fixedly installed on the template adjusting seat. One end of the adjusting screw is fixedly installed inside the nut, and the other end of the adjusting screw is horizontally fixedly installed on the template. The template can reciprocate relative to the cylinder mounting seat.

[0009] Furthermore, a motor mounting base is fixedly installed at the bottom of the motor, a slider is fixedly installed at the bottom of the motor mounting base, and a slide rail is fixedly installed at the top of the cylinder mounting base, with the slider and the slide rail slidably connected.

[0010] Secondly, this application also provides a saw blade trimming assembly, including a saw blade trimming column, a linear guide rail, a saw blade trimming cylinder, and a saw blade trimming cylinder. The linear guide rail is obliquely and fixedly installed on one side of the saw blade trimming column. It also includes a pair of saw blade extension and retraction adjustment devices of any of the above types. The saw blade extension and retraction adjustment devices are respectively slidably installed at the upper end and the lower end of the linear guide rail. The saw blade trimming cylinder is connected to the saw blade extension and retraction adjustment device located below the linear guide rail, and the saw blade trimming cylinder is connected to the saw blade extension and retraction adjustment device located above the linear guide rail.

[0011] The beneficial effects of this utility model are as follows:

[0012] By employing the aforementioned end-cut saw blade telescopic adjustment device, the motor is slidably mounted on the cylinder mounting base, while the template is set at one end of the cylinder mounting base. The cylinder is connected to the motor via a connecting arm. In this way, the motor and the end-cut saw blade can move telescopically relative to the cylinder mounting base under the drive of the cylinder. Adjusting the distance between the end-cut saw blade and the template can adjust the remaining length of the end-cut saw blade when cutting the edge banding tape. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] See appendix Figure 1 As shown, this embodiment provides a blade trimming assembly 10, including a blade trimming column 100, a linear guide rail 300, a blade trimming cylinder 400, a tail trimming cylinder 500, and a blade trimming telescopic adjustment device 200.

[0026] The linear guide rail 300 is inclined downwards, for example, installed at a 45° downward angle on one side of the end post 100. A pair of end saw blade telescopic adjustment devices 200 are respectively installed at the upper and lower ends of the linear guide rail 300, and the pair of end saw blade telescopic adjustment devices 200 are slidably installed on the linear guide rail 300, and can slide obliquely upwards or downwards along the linear guide rail 300.

[0027] In this embodiment, for ease of description, the end-aligning saw blade telescopic adjustment device 200 installed on the upper end of the linear guide rail 300 can be referred to as the upper end-aligning saw blade telescopic adjustment device, and the end-aligning saw blade telescopic adjustment device installed on the bottom end of the linear guide rail 300 can be referred to as the lower end-aligning saw blade telescopic adjustment device. The end-aligning cylinder 400 is connected to the lower end-aligning saw blade telescopic adjustment device and is used to drive the lower end-aligning saw blade telescopic adjustment device to move; the end-aligning cylinder 500 is connected to the upper end-aligning saw blade telescopic adjustment device and is used to drive the upper end-aligning saw blade telescopic adjustment device to move.

[0028] See attached document Figure 2 To be continued Figure 4As shown, in this embodiment, the end-cutting saw blade telescopic adjustment device 200 includes an end-cutting saw blade 203, a motor 202, a template 205, a cylinder 209, a cylinder mounting base 201, and a connecting arm 210. The end-cutting saw blade 203 is fixedly mounted on the output shaft of the motor 202, and is driven by the motor 202 to rotate and cut. The motor 202 is slidably mounted on the upper end face of the cylinder mounting base 201, and the sliding direction of the motor 202 is parallel to the axial direction of its output shaft. The cylinder 209 is fixedly mounted on the cylinder mounting base 201, and the piston rod of the cylinder 209 is fixedly connected to one end of the connecting arm 210. The other end of the connecting arm 210 is fixedly connected to the motor 202, so that the cylinder 209 can drive the motor 202 to telescopically move along the cylinder mounting base 201 via the connecting arm 210. The template 205 is located on the outer side of the cylinder mounting base 201, near one end of the end of the saw blade 203. The template 205 can reciprocate relative to the cylinder mounting base 201, that is, the installation position of the template 205 can be adjusted relative to the cylinder mounting base 201.

[0029] During the telescopic movement of the motor 202, the end-cutting saw blade 203 can be simultaneously telescopically moved, thereby adjusting the horizontal gap between the end-cutting saw blade 203 and the template 205, thus achieving adjustment of the cutting allowance of the edge banding strip. When cutting the edge banding strip, one end of the board (e.g., the front end) abuts against the end face of the template 205 (the principle of contact positioning between the board and the template 205 during edge banding strip cutting is existing technology and will not be described in detail here). Since the horizontal gap between the end-cutting saw blade 203 and the template 205 can be adjusted in this embodiment, when there is a horizontal gap between the end-cutting saw blade 203 and the template 205, since the end-cutting saw blade 203 and the template 205 are not located in the same vertical plane, the end-cutting saw blade 203 does not cut along the vertical plane where the template 205 is located when cutting the edge banding strip, but rather cuts in a vertical plane with a certain gap distance from the template 205 (i.e., in the vertical plane where the end-cutting saw blade 203 is located). For example, when a 1mm allowance is required, the motor 202 drives the saw blade 203 to move horizontally to the rear side of the template 205 (moving towards the side of the cylinder mounting seat 201 away from the template 205), so that there is a 1mm gap between the cutting plane of the saw blade 203 and the end face of the template 205 (the side that contacts the front end of the board). In this way, when the front end of the board abuts against the end face of the template 205, the saw blade 203 does not cut the edge banding strip on the board along the end face of the template 205, but cuts 1mm outside the front end face of the board. Thus, the edge banding strip will still leave a 1mm length on the board after cutting.

[0030] See attached document Figure 2 and attached Figure 3As shown, in some embodiments, the motor 202 is fixedly mounted on a motor mounting base 204, a slider 212 is fixedly mounted on the bottom end of the motor mounting base 204, and a slide rail 211 is fixedly mounted on the top end of the cylinder mounting base 201. The slider 212 is slidably connected to the slide rail 211.

[0031] See attached document Figure 3 and attached Figure 4 As shown, to prevent piston overtravel in cylinder 209 and protect the cylinder structure, the saw blade extension and retraction adjustment device 200 also includes an infeed limit screw 213 and a retraction limit screw 214. The infeed limit screw 213 is fixedly installed on the connecting arm 210, with one end extending horizontally towards one side of cylinder 209. The retraction limit screw 214 is fixedly installed on the connecting arm 210, with one end extending horizontally away from cylinder 209. The infeed limit screw 213 and retraction limit screw 214 prevent piston overtravel in cylinder 209 from damaging cylinder 209 and surrounding parts.

[0032] See attached document Figure 2 As shown, the telescopic adjustment device 200 for the end-cut saw blade also includes a template adjustment seat 206 and an adjustment screw 207. The template adjustment seat 206 is fixedly installed on the outer side of the cylinder mounting seat 201, and a nut 208 is fixedly installed on the template adjustment seat 206. One end of the adjustment screw 207 is fixedly installed inside the nut 208, and the other end of the adjustment screw 207 is horizontally fixedly installed on the template 205. The template 205 can reciprocate relative to the cylinder mounting seat 201. For example, there is a gap between the inner side of the template 205 and the cylinder mounting seat 201. When it is necessary to adjust the installation position of the template 205, the operator can rotate the adjustment screw 207. Since the adjustment screw 207 and the nut 208 fixedly installed on the template adjustment seat 206 are connected, the adjustment screw 207 can be adjusted. A threaded connection is formed, and the nut 208 is fixedly installed on the template adjustment seat 206. Therefore, as the adjusting screw 207 rotates, the adjusting screw 207 will move forward or backward relative to the template adjustment seat 206, thereby driving the template 205 to move forward or backward relative to the cylinder mounting seat 201. This allows for the front-to-back adjustment of the installation position of the template 205 on the cylinder mounting seat 201. The installation position of the template 205 can be adjusted front-to-back to better match the adjustment setting of the horizontal gap between it and the end-cutting saw blade 203. For example, after setting the piston stroke of the cylinder 209, when actually cutting the edge banding strip of the board, the position of the template 205 can be flexibly adjusted according to the cutting allowance accuracy of the edge banding strip in order to improve the cutting accuracy of the edge banding strip.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
