Description

Technical Field

[0001] This utility model relates to the field of picture frame processing equipment technology, and in particular to a picture frame corner cutting machine. Background Technology

[0002] The corner cutting machine can perform 45-degree bevel or polygonal cutting, and is suitable for cross-stitch picture frames, oil painting frames, wooden strips, etc. It is widely used in cross-stitch photo frame processing, photo studios, and oil painting frame production.

[0003] Chinese patent CN211466720U discloses a corner-cutting machine for picture frame production, including an equipment box, casters, a power cord, a worktable, a clamping component, a receiving component, a discharge trough, a first guide block, a second guide rail, and a second guide block; the casters are fixed to the bottom surface of the equipment box, and four casters are provided; the power cord is connected to the equipment box; the worktable is fixed to the top surface of the equipment box, and a cutting groove is provided on the worktable; the cutting device is fixed to the top of the equipment box and passes through the worktable, and its output end is aligned with the cutting groove; the clamping component and the discharge component are sequentially fixed to the top surface of the worktable.

[0004] In the above technical solution, the first guide block and the second guide block are used to position the wooden strip. When in use, the non-cut end of the wooden strip abuts against the positioning end face of the first guide block or the second guide block. However, the applicant found in the actual production process that most of the existing guide blocks have a vertical end face structure. When used, they only rely on the guide rail and the guide block to form an abutment positioning structure. The operator needs to hold the wooden strip and push the worktable to slide to complete the corner cutting operation. During the cutting process, the wooden strip will still have faults such as warping and displacement, resulting in insufficient corner cutting accuracy. As a result, when the wooden strip is spliced ​​into a picture frame, the splicing seam is not tight, which greatly affects the product quality. Utility Model Content

[0005] The purpose of this invention is to provide a picture frame corner cutting machine, which helps to solve the problem that some existing picture frame corner cutting machines have an imperfect limiting structure for wooden strips, thus affecting the cutting quality.

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.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] Please see Figures 1 to 4This embodiment discloses a picture frame corner cutting machine, which aims to enhance the stability of wooden strips during the cutting process by optimizing the limiting structure, ensuring the corner cutting accuracy, and thus improving the production quality of the picture frame.

[0030] The picture frame corner cutting machine in this embodiment specifically includes a frame 1, a worktable 2, a saw blade 3, a motor 4, a guide rail 5, and a limiting block 6. The frame 1 is welded from several aluminum alloy profiles, ensuring overall stability and durability. The worktable 2 is provided with a cutting groove 21 (front and back facing) with a linear through-hole groove structure to accommodate the rotational cutting of the saw blade 3. The center position (rotation axis) of the saw blade 3 is pivotally connected to the frame 1 and is driven by the motor 4 to rotate within the cutting groove 21.

[0031] The workbench 2 consists of a fixed part and a movable part. The fixed part is connected and fixed to the top of the frame 1, while the movable part is connected to the top of the fixed part by sliding back and forth. The movable part consists of two independent sliding plates distributed on the left and right sides. Its function is to reduce the weight of the movable part, making the manual pushing and pulling action more convenient and labor-saving when cutting wood strips.

[0032] The cutting groove 21 is provided with guide rails 5 on both the left and right sides, which are connected to two independent sliding plates. The guide rails 5 are inclined relative to the cutting groove 21. This design helps to better guide the wood strip during the cutting process to achieve the cut angle. The longitudinal profile of the guide rail 5 is "L" shaped, and its inner corner faces forward to tightly abut against the wood strip and prevent it from sliding during the cutting process.

[0033] A limiting block 6 is movably connected to the guide rail 5. The limiting block 6 is used to abut the non-cutting end of the wood strip. The front side of the limiting block 6 has an abutment end face 62, and the top of the abutment end face 62 also has a horizontal top plate 63. The space below the top plate 63 is adapted to the thickness of the wood strip to increase the stability of the wood strip in the vertical direction and prevent the wood strip from warping during the cutting operation. The limiting block 6 and the guide rail 5 together form a three-sided limiting structure for the wood strip. When the wood strip is placed on the guide rail 5 and the independent sliding plate is pushed back to the threshold position, precise corner cutting can be performed.

[0034] To further enhance flexibility, the motor 4 is connected to the frame 1 via a mounting base 41 with a tilting adjustment structure. The output end of the motor 4 is connected to the saw blade 3 via a belt assembly. The mounting base 41 allows for easy adjustment of the installation angle of the motor 4 according to actual needs, in order to achieve optimal tension.

[0035] The limiting block 6 includes a rectangular block-shaped main body 61, with an abutting end face 62 located on the side of the main body 61 near the cutting groove 21. The rear corner of the main body 61 abuts against the inner corner of the guide rail 5, ensuring stable movement of the limiting block 6 on the guide rail 5. A back plate 64 is provided on the rear side of the main body 61, fitted onto the back of the guide rail 5. A locking structure, specifically a locking bolt 65, is provided between the back plate 64 and the back of the guide rail 5. By tightening the locking bolt 65, the limiting block 6 can be firmly fixed to the guide rail 5, facilitating adjustment according to the size of the wooden strip. In other embodiments, scale lines can also be provided on the guide rail 5 to mark the installation position of the limiting block 6.

[0036] The independent sliding plate has several mounting holes for connecting and fixing the guide rail 5, which facilitates the installation and adjustment of the guide rail 5. In addition, the abutment end face 62 is designed as an inclined end face structure to adapt to the wood strip that has been cut on one side for limit control, which matches the inclined setting of the guide rail 5 and further enhances the stability of the wood strip during the cutting process.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
