[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0031] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0032] Reference Figures 1-7 As shown, a packaging box trimming mechanism includes: a base 100, on which a grinding head 105 is provided via an adjusting component 300 for trimming the sides of packaging boxes of different sizes; a bracket 101 is fixedly provided on the base 100; a movable plate 102 is mounted on the bracket 101 via a hydraulic rod 103; and two sets of opposing clamping blocks 104 with adjustable spacing for clamping packaging boxes of different sizes are provided on the movable plate 102 via a rotatable clamping component 200.

[0033] The base 100 is rotatably provided with a first turntable 107 for placing packaging boxes so that it can clamp multiple sides for trimming at one time. The base 100 is fixedly provided with a rotary motor 108 with its output shaft vertically upward and its top end fixedly connected to the first turntable 107. The bracket 101 is rotatably mounted with a second turntable 109 corresponding to the position of the first turntable 107 via a bearing 110. The clamping assembly 200 is fixedly provided on the second turntable 109.

[0034] In use, the packaging box to be trimmed is placed on the first turntable 107 on the base 100. The rotary motor 108 is stationary at this time. The hydraulic rod 103 is activated, driving the movable plate 102 to descend, bringing the clamping assembly 200 fixed on the second turntable 109 closer to the packaging box. By adjusting the clamping assembly 200, the two sets of clamping blocks 104 move relative to each other, stably clamping packaging boxes of different sizes between the first turntable 107 and the second turntable 109. According to the size of the packaging box, the position of the grinding head 105 is adjusted by adjusting the assembly 300 to align it with the side of the packaging box that needs trimming. The rotary motor 108 is activated, and the first turntable 107 drives the packaging box to rotate. At the same time, the grinding head 105 trims and polishes the side of the packaging box. Due to the rotation of the first turntable 107, multiple sides of the packaging box can be trimmed and trimmed at the same time. During the trimming process, the height of the movable plate 102 can be finely adjusted by the hydraulic rod 103 according to the actual situation to ensure the stability of the clamping and the trimming effect. The adjustable clamping component 200 enables stable clamping of packaging boxes of different sizes, improving the versatility and applicability of the trimming mechanism. This reduces the need for equipment replacement or complex adjustments due to different packaging box sizes, thus lowering production costs. The first turntable 107 and the cooperating second turntable 109 on the base 100 allow for multi-sided trimming of the packaging box in a single clamping operation, improving trimming efficiency, reducing the number of manual operations and time, and increasing production efficiency. The adjusting component 300 can adjust the position of the grinding head 105 to adapt to the trimming requirements of the sides of packaging boxes of different sizes, ensuring the precision and quality of trimming, and making the edges of the trimmed packaging boxes neater and smoother.

[0035] Reference Figure 7 As shown, the clamping assembly 200 includes: a mounting base 201, a slider 203, and a driving component; wherein,

[0036] The bottom surface of the second turntable 109 is fixedly provided with a mounting base 201. A horizontally arranged sliding groove 202 is provided on the mounting base 201. Two sets of sliders 203 are slidably arranged at intervals in the sliding groove 202. Each set of sliders 203 is fixedly installed with a clamping block 104 that contacts the side of the packaging box. The mounting base 201 is provided with a driving component to drive the sliders 203 to slide in the sliding groove 202.

[0037] In the above scheme, the driving component is activated, causing the slider 203 to slide within the groove 202. As the slider 203 slides, the clamping block 104 fixed to it also moves accordingly. The driving component precisely controls the sliding distance of the slider 203, allowing the spacing between the two sets of clamping blocks 104 to adapt to the side widths of packaging boxes of different sizes. When the clamping block 104 moves to the appropriate position and makes close contact with the side of the packaging box, it stably clamps the packaging box, preparing it for subsequent trimming operations. Throughout the trimming process, the clamping block 104 maintains a clamping force on the packaging box, ensuring that the packaging box is in a fixed position.

[0038] Reference Figure 7 As shown, the driving component includes: a servo motor 204, a rotating rod 205, and a connecting rod 206; wherein,

[0039] A servo motor 204 is fixedly installed in the middle section of the mounting base 201. The output shaft of the servo motor 204 is vertically downward and a parallel rotating rod 205 is fixedly installed at its top. Connecting rods 206 are respectively hinged to both ends of the rotating rod 205. One end of each set of connecting rods 206 is hinged to the slider 203.

[0040] In the above scheme, when the spacing of the clamping blocks 104 needs to be adjusted, the servo motor 204 starts, and its output shaft begins to rotate. The output shaft drives the rotating rod 205 to rotate synchronously. Since the connecting rods 206 at both ends of the rotating rod 205 are hinged to the slider 203 respectively, the rotation of the rotating rod 205 will change the angle between the connecting rod 206 and the rotating rod 205. As the rotating rod 205 rotates, the position of the connecting rod 206 changes. This change is transmitted to the slider 203 through the hinge point, causing the slider 203 to begin sliding within the slide groove 202. Because the connecting rods 206 at both ends of the rotating rod 205 move synchronously, the two sets of sliders 203 will move relative to or away from each other, thereby driving the clamping blocks 104 to adjust the spacing.

[0041] Reference Figures 4-6 As shown, the adjusting assembly 300 includes: a bidirectional lead screw 302, a mounting block 303, and a threaded block 304; wherein,

[0042] The base 100 is rotatably provided with a bidirectional lead screw 302. The bidirectional lead screw 302 has two sections of threads with opposite directions. Each section of thread is threaded with a threaded block 304. The side of the threaded block 304 is fixedly provided with an installation block 303. The base 100 has a horizontally arranged limiting groove 305 for the installation block 303 to slide. The grinding head 105 is rotatably mounted on the installation block 303. The base 100 is fixedly provided with a drive motor 301 with a horizontally arranged output shaft and its top end fixedly connected to the bidirectional lead screw 302.

[0043] When the position of the grinding head 105 needs to be adjusted according to the size of the packaging box, the drive motor 301 is started. The output shaft of the drive motor 301 drives the bidirectional lead screw 302 to rotate. Since the bidirectional lead screw 302 has two sections of threads with opposite directions, the rotation will cause the two threaded blocks 304 to move relative to or away from each other along the bidirectional lead screw 302. When the threaded blocks 304 move, the mounting block 303 fixed on its side also moves. The mounting block 303 slides in the limiting groove 305 opened on the base 100, thereby driving the grinding head 105 to move horizontally until the grinding head 105 reaches the appropriate position corresponding to the side of the packaging box to be repaired.

[0044] Reference Figures 1-2 As shown, the base 100 is provided with a dust collection assembly 400 for collecting dust generated during trimming.

[0045] In the above scheme, when the first turntable 107 drives the packaging box to rotate and the grinding head 105 trims the side of the packaging box, dust will be generated. At this time, the dust collection device of the dust collection assembly 400 is activated, generating negative pressure, which draws the dust generated during the trimming process into the dust collection chamber inside the dust collection assembly 400 through the air inlet.

[0046] Reference Figures 4-5 As shown, the dust collection assembly 400 includes a dust collection box 401 and a vacuum cleaner 403; the dust collection box 401 is provided inside the base 100, a handle 402 is fixedly provided on the dust collection box 401 on the outside of the base 100, and a vacuum cleaner 403 is fixedly provided on the base 100; multiple sets of dust discharge ports 404 are provided at intervals above the mounting base 201 on the base 100.

[0047] When the first turntable 107 rotates the packaging box and the polishing head 105 trims the sides of the box, a large amount of dust is generated. The vacuum cleaner 403 starts, and its powerful suction draws the dust generated during trimming into the dust collection box 401 through the dust inlet 404. Since there are multiple sets of dust inlets 404 spaced apart above the mounting base 201, they can comprehensively cover the areas where dust may be generated during trimming, ensuring that the dust is collected in a timely and effective manner.

[0048] Reference Figure 2 As shown, the bottom surface of the base 100 is fixedly provided with an anti-slip pad 106.

[0049] In the above solution, the anti-slip pad 106 significantly increases the friction between the trimming mechanism and the supporting plane, effectively preventing the equipment from shifting or shaking during operation due to vibration, external forces, or other factors. This is crucial for ensuring trimming accuracy, avoiding trimming position deviations caused by equipment movement, and improving product quality.

[0050] In summary, the packaging box trimming mechanism provided by this utility model allows the packaging box to be trimmed to be placed on the first turntable 107 of the base 100 during use. The hydraulic rod 103 is activated, causing the movable plate 102 to descend, which in turn drives the clamping assembly 200 fixed on the second turntable 109 closer to the packaging box. Based on the size of the packaging box, the servo motor 204 in the clamping assembly 200 is activated. The output shaft of the servo motor 204 rotates, causing the rotating rod 205 to rotate. The connecting rods 206 hinged at both ends of the rotating rod 205 push the slider 203 to slide relative to each other within the slide groove 202, thereby causing the clamping blocks 104 fixed on the slider 203 to move until the two sets of clamping blocks 104 are tightly fitted against the side of the packaging box, completing the stable clamping of the packaging box. At this time, the second turntable 109 cooperates with the first turntable 107 to firmly clamp the packaging box between them. Observing the position of the side of the packaging box to be trimmed, the drive motor 301 in the adjustment assembly 300 is activated. The output shaft of the drive motor 301 drives the bidirectional lead screw 302 to rotate. Because the two threads on the bidirectional lead screw 302 have opposite directions, the threaded block 304 moves relative to or away from the lead screw 302, thereby causing the mounting block 303 fixed to the side of the threaded block 304 to slide within the limiting groove 305. This ultimately moves the grinding head 105 on the mounting block 303 to a position precisely corresponding to the side of the packaging box to be trimmed. The rotary motor 108 is then activated, its output shaft driving the first turntable 107 to rotate, causing the clamped packaging box to begin rotating. The vacuum cleaner 403 is activated, generating suction that collects dust generated during the trimming process through multiple dust collection ports 404 located above the mounting base 201 on the base 100, preventing dust from scattering. The grinding head 105 rotates on the mounting block 303, performing trimming operations on the rotating side of the packaging box. During the trimming process, the height of the movable plate 102 can be finely adjusted via the hydraulic rod 103 according to the trimming effect and the packaging box material, ensuring clamping stability and trimming quality. Because the first turntable 107 rotates continuously, it can clamp and trim multiple sides of the packaging box at once.
