Description

Technical Field

[0001] This utility model relates to the technical field of integrated box packing and labeling machines, and in particular to an automatic assembly line box packing and labeling machine. Background Technology

[0002] The automated box-packing and labeling machine is an integrated automated equipment that combines boxing and labeling functions. It is widely used in production lines for various products such as food, pharmaceuticals, and electronics. Its main function is to first pack the boxes according to preset specifications using an integrated mechanical structure and control system after the products are packaged into boxes, and then affix labels to the packed boxes. This achieves continuous and automated operation of the boxing and labeling processes, significantly improving production efficiency, reducing labor costs, and meeting the needs of modern large-scale production. While existing automated box-packing and labeling machines have achieved automated integration of packing and labeling, significant shortcomings remain in practical applications. Specifically, during labeling, the force generated by the contact between the labeling mechanism and the box surface can easily cause the box to slide and deviate on the conveyor belt. This sliding not only prevents labels from being accurately placed in the preset position, resulting in skewed or misaligned labels and severely affecting labeling quality and product appearance regularity; it also prevents the slid-off boxes from entering subsequent processes along the predetermined trajectory, disrupting the production line's rhythm and even causing equipment jams, negatively impacting the efficiency of subsequent warehousing and transportation processes.

[0003] Therefore, it is necessary to provide a new automated assembly line box packing and labeling machine to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic assembly line box packing and labeling machine.

[0005] The automatic box packing and labeling machine provided by this utility model includes: an integrated machine body, which consists of a packing area and a labeling area; a conveyor belt is provided at the bottom of the integrated machine body, and a box is placed on the upper surface of the conveyor belt; a slide rail is fixedly connected to one end of the integrated machine body near the labeling area, and the slide rail is located above the conveyor belt; limit plates are symmetrically installed on one side of the slide rail near the conveyor belt, and the limit plates and the slide rail together limit the box; a rotating rod is fixedly connected to one end of the limit plate near the slide rail; the slide rail has symmetrically opened grooves inside, and a slider is slidably connected in each of the two grooves. The slider is C-shaped, and the two sliders are rotatably connected to the two ends of the rotating rod at the corresponding positions; a bidirectional threaded rod is rotatably connected inside the slide rail, and the two ends of the bidirectional threaded rod are threadedly connected to the middle of the two sliders. The bidirectional threaded rod drives the sliders to slide, thereby adjusting the distance between the two limit plates.

[0006] Preferably, a first worm gear is rotatably connected inside the top end of each of the two sliders, the first worm gear is fixedly connected to the top end of the rotating rod, and a first worm is rotatably connected inside the top end of each slider, the first worm meshing with the first worm gear.

[0007] Preferably, the top of the slide rail is rotatably connected to a drive rod, and the two opposing ends of the first worm gears extend out of the slider and are fixedly connected to a driven rod. The driven rod and the drive rod are slidably connected by a spline.

[0008] Preferably, a second worm gear is rotatably connected inside the top end of the slide rail, the inner wall of the second worm gear is fixedly connected to the outer wall of the middle part of the drive rod, and a second worm is rotatably connected inside the top end of the slide rail, with the second worm gear meshing with the second worm.

[0009] Preferably, a motor is fixedly connected inside the top of the slide rail, and the output end of the motor is fixedly connected to one end of the second worm gear.

[0010] Preferably, a knob is rotatably connected to the end of the slide rail away from the main body of the integrated machine, and the knob is fixedly connected to one end of the bidirectional threaded rod.

[0011] Compared with related technologies, the automatic assembly line box packing and labeling machine provided by this utility model has the following beneficial effects: 1. Precise positioning and anti-slip design ensure labeling quality and operational continuity. Addressing the core pain point of easy slippage of the labeling box during labeling in existing equipment, this utility model utilizes a motor-driven transmission component and a limiting plate to form a collaborative limiting structure. When the box is conveyed to the labeling area and its center aligns with the center of the slide rail, the motor sequentially drives the second worm, second worm wheel, driving rod, driven rod, first worm, and first worm wheel to rotate. Ultimately, the rotating rod drives the limiting plate to rotate 90° and tightly clamp the side wall of the box. This bidirectional clamping limiting method effectively counteracts the force generated by the contact between the labeling mechanism and the box, completely preventing the box from slipping or deviating on the conveyor belt. This ensures that the label is accurately pasted in the preset position, solving the problems of labeling skew and misalignment, and also ensures that the box enters the subsequent process along the predetermined trajectory after labeling, avoiding production line jams or rhythm disruptions, and improving the overall continuity of operations. II. The spacing is adjustable and adaptable to a wide range of container sizes, meeting the operational needs of various container specifications. This invention utilizes a threaded engagement structure between a bidirectional threaded rod and a slider to achieve flexible adjustment of the spacing between the limiting plates. Rotating the knob at the end of the slide rail drives the bidirectional threaded rod to rotate. Since the threads at both ends of the bidirectional threaded rod are in opposite directions and are threadedly connected to two C-shaped sliders respectively, the rotational motion of the threaded rod can be converted into the sliding of the two sliders along the slide groove in opposite directions or back-to-back. This, in turn, drives the limiting plates to move synchronously via a rotating rod to adjust the spacing. This adjustment structure requires no disassembly of parts, is simple and quick to operate, and can adapt to boxes of different lengths, breaking the limitations of existing equipment that is only compatible with single-size boxes, and improving the equipment's versatility in various production scenarios across multiple fields such as food, pharmaceuticals, and electronics.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 5An automatic assembly line box packing and labeling machine is disclosed. The machine includes: an integrated machine body 1, comprising a packing area 2 and a labeling area 3; a conveyor belt 4 at the bottom of the machine body 1, with a box 5 placed on its upper surface; a slide rail 6 fixedly connected to one end of the machine body 1 near the labeling area 3, the slide rail 6 being located above the conveyor belt 4; limit plates 7 symmetrically installed on one side of the slide rail 6 near the conveyor belt 4, the limit plates 7 and the slide rail 6 jointly limiting the box 5; a rotating rod 8 fixedly connected to one end of the limit plate 7 near the slide rail 6; and the slide rail... The slide rail 6 has symmetrically arranged grooves 9 inside, and two sliders 10 are slidably connected in each of the two grooves 9. The sliders 10 are of the C-shape design. The two sliders 10 are rotatably connected to the two ends of the rotating rod 8 at the corresponding positions. The slide rail 6 has a bidirectional threaded rod 11 rotatably connected inside. The two ends of the bidirectional threaded rod 11 are threadedly connected to the middle of the two sliders 10. The bidirectional threaded rod 11 drives the sliders 10 to slide, thereby adjusting the distance between the two limiting plates 7. A knob 19 is rotatably connected to the end of the slide rail 6 away from the integrated machine body 1. The knob 19 is fixedly connected to one end of the bidirectional threaded rod 11.

[0017] It should be noted that when the box is packed and ready to be labeled, the middle of the box 5 should correspond to the middle of the slide rail 6. At this time, the limiting plate 7 should rotate and move closer to the box 5. The limiting plate 7 should clamp the box 5 to limit the box 5 before labeling. This will prevent the box 5 from sliding during labeling, which would not only affect the labeling effect but also affect subsequent operations.

[0018] Please see Figures 3 to 5 Both sliders 10 have a first worm gear 12 rotatably connected to their top ends, and the first worm gear 12 is fixedly connected to the top end of the rotating rod 8. Both sliders 10 also have a first worm 13 rotatably connected to their top ends, meshing with the first worm gear 12. A drive rod 14 is rotatably connected to the top end of the slide rail 6. One end of each of the two first worm gears 13 extends out of the slider 10 and is fixedly connected to a driven rod 15, which is slidably connected to the drive rod 14 via a spline. A second worm gear 16 is rotatably connected to the top end of the slide rail 6, and its inner wall is fixedly connected to the outer wall of the middle part of the drive rod 14. A second worm 17 is rotatably connected to the top end of the slide rail 6, meshing with the second worm gear 16. A motor 18 is fixedly connected to the top end of the slide rail 6, and the output end of the motor 18 is fixedly connected to one end of the second worm 17.

[0019] It should be noted that when the slider 10 slides, the driven rod 15 slides synchronously with the slider 10. At this time, the driven rod 15 slides along the inner wall of the driving rod 14. Since the driving rod 14 and the driven rod 15 are connected by a spline, when the driving rod 14 rotates, the driving rod 14 can still drive the driven rod 15 to rotate.

[0020] The working principle of the automatic assembly line box packing and labeling machine provided by this utility model is as follows: In the initial state, the two limiting plates 7 are in the unfolded state, that is, the two limiting plates 7 are opened in a straight line, so that the box 5 can move to the labeling area 3 with the conveyor belt 4. After the box 5 completes the packing operation in the packing area 2, it is transported to the labeling area 3 by the conveyor belt 4 at the bottom of the integrated machine body 1. At this time, the middle of the box 5 is precisely aligned with the middle of the slide rail 6, and the limit preparation process before labeling is started. The motor 18, fixed inside the top of the slide rail 6, is activated. The output of the motor 18 drives the second worm gear 17 to rotate. The second worm gear 17 meshes with the second worm wheel 16, which is fixedly sleeved in the middle of the active rod 14. This causes the active rod 14 to rotate inside the top of the slide rail 6. The active rod 14 is slidably connected to two driven rods 15 via splines. It can move with the slider 10 to adapt to the length. The rotation of the active rod 14 is synchronously transmitted to the two driven rods 15, which in turn drives the first worm gear 13, which is fixedly connected to the driven rods 15, to rotate. The first worm gear 13 meshes with the first worm wheel 12 inside the top of the slider 10. The first worm wheel 12 is fixedly connected to the top of the rotating rod 8. Finally, the rotating rod 8 drives the limiting plate 7 to rotate 90°, so that the limiting plate 7 fits tightly against the side wall of the box 5, achieving bidirectional clamping and limiting of the box 5. In this state, when the labeling mechanism applies labels to the box 5, the labeling force prevents the box 5 from sliding or shifting on the conveyor belt 4. This ensures the accuracy of the label placement, avoiding label skew or misalignment, and also ensures that the box 5 can proceed to the next process along the predetermined trajectory after labeling, maintaining the stability of the assembly line operation rhythm. After labeling is completed, the motor 18 reverses, driving all transmission components to reset, the limit plate 7 disengages from the box 5, and the box 5 is transported to the next stage by the conveyor belt 4, completing a single labeling and limiting cycle. For different sizes of housing 5, the spacing of the limiting plates 7 can be adjusted by rotating the knob 19. Rotating the knob 19 at the end of the slide rail 6 away from the main body 1 causes the double-threaded rod 11, which is fixedly connected to it, to rotate inside the slide rail 6. Since the two ends of the double-threaded rod 11 are respectively threaded to the middle of the two C-shaped sliders 10 in the slide groove 9 of the slide rail 6, the rotational motion of the threaded rod is converted into the two sliders 10 sliding towards or away from each other along the slide groove 9. This, in turn, drives the limiting plates 7 to move synchronously through the rotating rod 8 until the spacing between the two sides of the limiting plates 7 is equal to the length of the corresponding size housing 5.
