Description

Technical Field

[0001] This utility model relates to the field of packaging box equipment technology, specifically a high-speed automated color box gluing device with adjustable positioning blocks. Background Technology

[0002] In the field of mass production of color boxes, high-speed automated gluing equipment has become the mainstream equipment in the industry due to its ability to significantly improve production efficiency. However, existing equipment has significant shortcomings in positioning accuracy and specification adaptability. The positioning blocks of traditional gluing equipment are mostly fixed structures. When processing color boxes of different sizes, the blocks need to be disassembled and replaced, which is a cumbersome and time-consuming process that seriously restricts the continuity of production. Even if some equipment is equipped with adjustable blocks, they often lack precision guiding mechanisms and rely on manual coarse adjustment. There are no stable fine-tuning drive components, resulting in low adjustment accuracy. Moreover, the blocks are prone to displacement due to equipment vibration during high-speed operation. At the same time, existing blocks are mostly rigid designs, which are prone to impact when in high-speed contact with the gluing edge of the color box, causing scratches or indentations on the surface of the color box. The reliability of the locking mechanism after adjustment is insufficient, which further aggravates the positioning offset and causes problems such as misalignment of glue application, uncontrolled glue amount (overflow or detachment), and loose pressing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, this utility model provides a high-speed automated color box gluing device with adjustable positioning blocks, including a frame 1, a conveying mechanism 101 mounted on the frame 1, an adhesive application mechanism 3 and a pressing mechanism 4 located above the conveying mechanism 101, and an adjustable positioning block mechanism 2. The adjustable positioning block mechanism 2 includes a fixed base 202 located on one side of the conveying mechanism 101, a positioning block assembly, a fine-tuning drive mechanism and a locking mechanism 208. The fixed base 202 is fixedly mounted on the frame 1, and a guide structure 204 is provided on the fixed base 202. The guide structure 204 is at least one precision linear guide rail 207 mounted on the fixed base 202.

[0024] Before mass production of color boxes, the adjustable positioning stop mechanism 2 needs to be pre-positioned according to the current size of the color boxes (especially the position of the adhesive edge). Loosen the locking bolts on the adjusting base 201 (the bolts pass through the elongated hole of the adjusting base 201 and engage with the threaded hole of the fixed base 202) to release the locking state of the adjusting base 201 and the fixed base 202. The fine-tuning drive mechanism is used to drive the adjusting base 201 together with the stop body 203 to perform linear displacement in a direction parallel to the positioning working surface, so as to achieve precise adjustment of the lateral position of the positioning working surface relative to the conveying mechanism 101. There are two or more adjustable positioning stop mechanisms 2, symmetrically arranged along the conveying direction, each corresponding to a different adhesive edge positioning station of the color box.

[0025] The linear displacement of the positioning block is achieved through a fine-tuning drive mechanism (adjusting screw 209 + adjusting nut 210). Since the adjusting nut 210 is fixed to the fixed base 202 of the frame 1, and one end of the adjusting screw 209 is rotatably connected to the adjusting base 201 via a bearing, rotating the adjusting screw 209 pushes / pulls the adjusting base 201 along the nut axis. Simultaneously, the adjusting base 201 slides against the precision linear guide 207 of the fixed base 202 via the slider 206, ensuring that the adjusting base 201 moves smoothly only in a direction parallel to the positioning working surface, avoiding deviation. Once the positioning working surface of the block body 203 (located above the conveying plane of the conveying mechanism 101) aligns with the preset positioning position of the color box adhesive edge, the locking bolts are tightened to rigidly lock the adjusting base 201 and the fixed base 202, preventing positioning deviation due to vibration during high-speed operation.

[0026] The adjusting base 201 and the guide structure 204 form a sliding fit. The positioning working surface is set above one side of the conveying plane of the conveying mechanism 101 and can accurately abut and position with the adhesive edge of the color box in the gluing and pressing station.

[0027] The positioning block assembly includes a block body 203 and an adjusting base 201 fixedly connected to the block body 203. The block body 203 is provided with a positioning working surface for blocking and positioning the adhesive edge of the color box. The fine-tuning drive mechanism is connected between the fixed base 202 and the adjusting base 201. The locking mechanism 208 is provided on the adjusting base 201 or the fixed base 202 and is used to lock the adjusting base 201 and the fixed base 202 relative to each other after adjustment. The adjusting base 201 is slidably engaged with the precision linear guide 207.

[0028] Once the positioning working surface of the stop block body 203 (located above one side of the conveying plane of the conveying mechanism 101) is aligned with the preset positioning position of the color box adhesive edge, tighten the locking bolts to rigidly lock the adjusting base 201 and the fixed base 202 to prevent positioning deviation caused by vibration during high-speed operation.

[0029] The color box to be glued is placed on the conveyor mechanism 101 (high-speed synchronous belt conveyor line 102), and the synchronous belt drives the color box to move along the conveying direction at a preset high speed. The position detection sensor on the frame 1 monitors the position of the color box in real time. When the front end (or glued edge) of the color box reaches the predetermined positioning station, the sensor sends a trigger signal to the control system to synchronize and coordinate the start sequence of the positioning and gluing processes to avoid process misalignment.

[0030] Upon receiving the sensor signal, the conveying mechanism 101 briefly maintains a constant speed (or finely adjusts the speed) to ensure precise contact between the adhesive edge of the color box and the positioning working surface of the locked positioning block. At this time, the positioning working surface, through rigid support, restricts the lateral displacement of the color box, ensuring the positional accuracy of the adhesive edge. Simultaneously, the elastic buffer plate 205 (detachable, partially connected by magnetic attraction) on the positioning working surface buffers the impact force between the color box and the block, preventing scratches or indentations on the color box surface. After the color box is stably positioned, the control system drives the glue application mechanism 3 (quantitative dispensing valve 301) to precisely apply glue to the adhesive edge of the color box. The quantitative dispensing valve 301 can precisely control the amount of glue (avoiding excessive glue overflow or insufficient glue causing detachment), and the glue application position is highly accurate due to the precise positioning of the color box, ensuring uniform and non-offset glue application to the adhesive edge.

[0031] After the adhesive is applied, the conveying mechanism 101 continues to move the color box towards the pressing mechanism 4 (elastic pressure roller group 401). Once the color box enters the pressing station, the elastic pressure roller group 401 presses the adhesive edges of the color box with a preset, moderate pressure. The design of the elastic pressure rollers can adapt to slight differences in the thickness of the color box (such as material elastic deformation), ensuring a tight press without damaging the color box. The pressed color box is then conveyed to the end of the device via a synchronous belt, completing the entire box-gluing process and entering the subsequent collection or processing stage.

[0032] Furthermore, the fine-tuning drive mechanism includes an adjusting screw 209 and an adjusting nut 210. One end of the adjusting screw 209 is rotatably mounted on the adjusting base 201 via a bearing, and the adjusting nut 210 is fixedly mounted on the fixed base 202 and screwed onto the adjusting screw 209.

[0033] Two or more adjustable positioning block mechanisms 2 are symmetrically arranged along the conveying direction, which can respectively position different bonding edges such as the left and right sides of the color box, adapting to various box gluing requirements such as "single bonding edge" and "double bonding edge". The end of the adjusting screw 209 can be equipped with a handwheel or hexagonal interface, which can achieve fine adjustment by manual rotation without professional tools, making it intuitive and easy to understand.

[0034] The adjustment base 201 moves linearly along a fixed trajectory without lateral deviation, ensuring high guiding accuracy. The adjustment screw 209 and nut use precision threads (such as trapezoidal threads), ensuring a stable transmission ratio. The fine-tuning drive mechanism can achieve an adjustment stroke of 50-100mm (depending on the guide rail length), covering the mainstream color box size range.

[0035] Furthermore, the adjustment base 201 is provided with a slider 206 that is connected to the precision linear guide rail 207.

[0036] The fixed base 202 is rigidly connected to the frame 1 by bolts. The clearance between the adjustable base 201 and the guide rail is ≤0.01mm. The stop block does not resonate or shift during high-speed operation.

[0037] Furthermore, the locking mechanism 208 includes a locking bolt, which passes through the elongated hole on the adjusting base 201 and is screwed into the threaded hole on the fixed base 202.

[0038] Furthermore, the thread has self-locking properties, and temporary fixation can be achieved without additional limiters after adjustment. The locking bolt rigidly locks the adjusting base 201 and the fixed base 202 through the elongated hole (adapted to the adjustment stroke).

[0039] Furthermore, the positioning working surface is also provided with an elastic buffer plate 205, which is detachably connected to the stop block body 203.

[0040] The working surface is precisely perpendicular (or at a preset angle) to the conveying plane and is located above one side of the conveying plane, ensuring "surface contact" with the adhesive edge of the color box, providing better positioning stability than point contact. Using an elastic material with a Shore hardness of 50-70, it forms a "soft contact" during positioning, buffering the impact of the color box against the stop and avoiding surface dents or scratches caused by rigid collisions.

[0041] Furthermore, the elastic buffer plate 205 is connected to the stop body 203 via a magnetic structure.

[0042] The elastic buffer plate 205, which is connected by magnetic attraction or bolts, can be replaced with buffer materials of different hardness (such as silicone or rubber) according to the material of the color box (such as cardboard or corrugated paper) to avoid positioning damage caused by material differences.

[0043] Furthermore, it also includes a position detection sensor for detecting whether the color box has reached a predetermined position and triggering the gluing or pressing action, the position detection sensor being mounted on the frame 1.

[0044] The position detection sensor (such as a photoelectric sensor with a response time of ≤1ms) is linked with the gluing and pressing mechanism 4 to ensure precise connection of the "positioning-gluing-pressing" sequence without waiting time.

[0045] Furthermore, the conveying mechanism 101 includes a high-speed synchronous belt conveyor line 102, the glue application mechanism 3 includes a quantitative glue dispensing valve 301, and the pressing mechanism 4 includes an elastic pressure roller group 401.

[0046] High-strength synchronous belts (such as fiberglass core synchronous belts) are used, ensuring high transmission accuracy and wear resistance. This allows for long-term, stable high-speed conveying without slippage. The quantitative dispensing valve 301 is a pneumatic or electric dispensing valve with a dispensing speed ≤0.5 seconds / piece, matching the high-speed conveying rhythm and preventing process interruptions caused by dispensing lag.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
