[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: a device for trimming edge strips, comprising a device clamping block 1 and a clamping arm 3, a fixed shaft 2 is installed inside the device clamping block 1, and two clamping arms 3 are installed on the surface of the fixed shaft 2, a limit block 4 is arranged on the inner side of the clamping arm 3, and a spring 5 is connected to the inner side of the limit block 4, a connecting plate 7 is installed at the end of the clamping arm 3, and a driving motor 8 is connected to the inner side of the connecting plate 7, and a grinding disc 9 is installed at the output end of the driving motor 8, an L-shaped rod 10 is connected to the left side of the driving motor 8, and a cutting structure 11 is installed at the end of the L-shaped rod 10, and a fixing rod 14 is arranged in the cutting structure 11, a connecting rod 6 is installed on the left side of the device clamping block 1, and a fixing block 12 is installed at the end of the connecting rod 6, and a roller 13 is arranged on the rear side of the fixing block 12.

[0023] The bottom of the cutting structure 11 is on the same horizontal line as the grinding sheet 9, and the grinding sheets 9 are centrally symmetrical. When trimming, by pressing the clamping arm 3, the grinding sheet 9 and the bottom of the cutting structure 11 are clamped on both sides of the edge banding for trimming. Since the cutting structure 11 is on the left side of the grinding sheet 9, the edge banding will first be cut by the cutting structure 11 at the higher edge, and then polished by the grinding sheet 9 for a second trimming, thereby improving the trimming quality.

[0024] The cutting structure 11 includes a cutting knife 1101, a U-shaped plate 1102, a connecting block 1103 and an L-shaped angle iron 1104. The right side of the cutting knife 1101 is fixed to the U-shaped plate 1102 via bolts. The top of the U-shaped plate 1102 is connected to the connecting block 1103, and the top of the connecting block 1103 is installed on the end of the L-shaped rod 10. The L-shaped angle iron 1104 is installed on the periphery of the L-shaped rod 10 via a bearing. When the cutting knife 1101 needs to be replaced, the bolts are removed from the right side of the U-shaped plate 1102 to release the fixation of the cutting knife 1101, and then the cutting knife 1101 can be pulled out and replaced. Such a structure can reduce a certain replacement time, and the L-shaped angle iron 1104 on the periphery of the L-shaped rod 10 can prevent the cutting knife 1101 from scratching the hand, thereby increasing personal safety.

[0025] Two notches corresponding to the fixing rod 14 are provided on the top of the connecting block 1103, and the two notches are respectively opened on the front and left sides of the top of the connecting block 1103. The cutting knife 1101 can be changed into two modes by rotating the L-shaped angle iron 1104. One is the protection mode when the connecting block 1103 is in the left notch, and the other is to pull the fixing rod 14 to make it disengage from the left notch of the connecting block 1103, thereby releasing the fixation of the L-shaped angle iron 1104, and then move the L-shaped angle iron 1104 to the front notch of the connecting block 1103 through the bearing, so that the cutting knife 1101 is exposed to the outside of the working mode.

[0026] The limit blocks 4 are centrally symmetrical and connected via springs 5. When working, the grinding pieces 9 arranged at the ends of the limit blocks 4 can be changed into different grinding sizes via the springs 5, thereby increasing the applicability.

[0027] The inner side of the roller 13 is parallel to the front end of the connecting plate 7. When cutting, the inner side of the roller 13 will be attached to the front side of the edge banding, and the grinding disc 9 will also be attached to the protruding sides of the edge banding through the clamping arm 3, thereby grinding it and increasing the accuracy of its trimming.

[0028] Working principle: When using the edge banding trimming device, first, pull the fixing rod 14 to disengage it from the left notch of the connecting block 1103, thereby releasing the fixation of the L-shaped angle iron 1104. Then, the L-shaped angle iron 1104 is moved to the front notch of the connecting block 1103 through the bearing, so that the cutting blade 1101 is exposed and enters the working mode.

[0029] Next, align the connecting rod 6 on the left side of the clamping block 1 parallel to the front of the edge banding, and then fit the inner side of the roller 13 inside the fixing block 12 to the front of the edge banding. Then, press the clamping arm 3 connected to the surface of the fixing shaft 2 to clamp the grinding disc 9 and the bottom of the cutting structure 11 at the end of the L-shaped rod 10 on both sides of the edge banding to trim it.

[0030] Next, the power is turned on to start the driving motor 8 at the bottom of the connecting plate 7, thereby driving the grinding disc 9 to rotate. Since the cutting structure 11 is on the left side of the grinding disc 9, the edge banding will first be cut by the cutting structure 11 at the higher edge, and then polished by the grinding disc 9 for secondary trimming, thereby improving the quality.

[0031] After the trimming is completed, the clamping arm 3 is reset by the spring 5 between the limit blocks 4, and then the fixing rod 14 is pulled to adjust the L-shaped angle iron 1104 back to the left notch of the connecting block 1103, turning it into a protection mode, thereby preventing the cutting knife 1101 from scratching the hand, thereby increasing personal safety.

[0032] Finally, when the cutting knife 1101 needs to be replaced, the bolt is removed from the right side of the U-shaped plate 1102 to release the fixation of the cutting knife 1101, and then the cutting knife 1101 can be pulled out and replaced, which reduces a certain amount of replacement time. The contents not described in detail in this manual are all existing technologies known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
