Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a positioning conveyor device that can quickly adapt to packaging boxes of different specifications. Background Technology

[0002] In the packaging industry, packaging machines need to pass the packaging boxes through multiple stations in sequence, such as tray feeding, material feeding station, border strip, and top cover.

[0003] Existing packaging machine conveyor tables typically use fixed limiting structures to transport and position packaging boxes. When changing to packaging boxes of different sizes (especially those with different widths), operators need to manually adjust the position of the limiting blocks. This method is not only cumbersome and inefficient, but also makes it difficult to guarantee positioning accuracy, resulting in poor equipment versatility and adaptability, and affecting the overall efficiency and flexibility of the production line. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a packaging box positioning and conveying device for a packaging machine, so as to solve the technical problems of poor adaptability and low efficiency caused by manual adjustment of the limit in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging box positioning and conveying device for a packaging machine, characterized in that it includes a conveying table, the conveying table is provided with at least two parallel pushing belts, and a positioning belt is provided between the pushing belts; the pushing belts are driven by a first motor, the positioning belts are driven by a second motor, the outer surface of the pushing belts is evenly distributed with pushing protrusions, and the outer surface of the positioning belts is evenly distributed with positioning protrusions. During operation, the pushing belts push the packaging box forward from the rear side of the packaging box, and the positioning belts clamp and position the conveyed packaging box from the front side of the packaging box.

[0006] Furthermore, a first rotating shaft is provided at the front end of the conveyor platform, and a second rotating shaft is provided at the rear end; the front pulley of the push belt is fixedly installed on the first rotating shaft, the rear pulley of the push belt is rotatably installed on the second rotating shaft through a bearing, the front pulley of the positioning belt is rotatably installed on the first rotating shaft through a bearing, and the rear pulley of the positioning belt is fixedly installed on the second rotating shaft.

[0007] Furthermore, the conveyor platform is equipped with an adjustable limiting mechanism for adjusting the conveying width.

[0008] Furthermore, the adjustable limiting mechanism includes a pair of parallel limiting baffles, a guide rail extending along the width of the conveyor table, two sliders that can slide along the guide rail, a bidirectional screw, and a servo motor for driving the bidirectional screw to rotate; the two limiting baffles are respectively fixed to the corresponding sliders, and the limiting baffles are in the shape of a "T"; the two limiting baffles are respectively provided with threaded sleeves that are threadedly engaged with the bidirectional screw, and the two threaded segments on the bidirectional screw rotate in opposite directions.

[0009] Furthermore, a support is provided above the conveyor table, and the guide rail, slider, bidirectional screw and servo motor are all mounted on the support.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. High degree of automation and strong adaptability: By setting up a bidirectional screw driven by a servo motor and an adjustable limit mechanism, the automatic and rapid adjustment of the distance between the two limit baffles is realized without manual intervention. It can quickly and accurately adapt to packaging boxes of various widths and specifications, significantly improving the versatility and production efficiency of the equipment.

[0011] 2. Good coordination between conveying and positioning: The conveyor adopts a layout of double push belts plus a middle positioning belt. The push belts are responsible for providing conveying power, while the middle positioning belt can effectively prevent the packaging box from shifting or tipping during the conveying process. The two work together to ensure the stability of the packaging box conveying process and the accuracy of positioning.

[0012] 3. Compact structure and reliable operation: The pulley's cross-shaft bearing mounting design allows each positioning belt to be independently driven by a second motor, resulting in a more compact structure, shorter transmission path, fewer potential failure points, and guaranteed operational reliability. The addition of push and positioning ridges increases friction with the packaging box, further enhancing the stability of conveying and positioning.

Detailed Implementation

[0016] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] like Figure 1 , Figure 2 As shown, this utility model provides a packaging box positioning and conveying device for a packaging machine. Its core lies in its mechatronics design, which enables automatic adjustment of the conveying width to accommodate packaging boxes of different sizes.

[0018] Example: A packaging box positioning and conveying device for a packaging machine in this example includes a conveyor table 100. The main frame of the conveyor table 100 forms the base of the entire device. A first rotating shaft 210 is installed at one end of the conveyor table 100, and a second rotating shaft 220 is installed at the other end. The first rotating shaft 210 is driven by a first motor and is mainly responsible for precisely controlling the conveying action; the second rotating shaft 220 is driven by a second motor and provides the main positioning assistance. Two parallel push belts 310 are wound around the first rotating shaft 210 and the second rotating shaft 220 via first pulleys 510 (two are installed on each rotating shaft) for directly pushing the packaging box forward. More importantly, a positioning belt 320 is also wound around the first rotating shaft 210 and the second rotating shaft 220. The positioning belt 320 is located at the center position between the two push belts 310. The first motor and the second motor are servo motors.

[0019] To achieve this structure, the second pulley 520 (the rear pulley of the positioning belt) is rotatably mounted on the first shaft 210 via bearings, while the first pulley 510 (the front pulley of the push belt) is rotatably mounted on the second shaft 220 via bearings. This design allows the positioning belt 320 and the push belt 310 to be controlled independently.

[0020] The outer surface of the push belt 310 is evenly distributed with vertical push protrusions 311 for pushing the packaging box; the outer surface of the positioning belt 320 is evenly distributed with transverse positioning protrusions 321 for providing lateral constraint on the front side of the packaging box. The packaging box is positioned between the push protrusions and the positioning protrusions. When the push protrusions 311 move with the push belt 310, they push the packaging box forward, while the positioning protrusions 321 move in the opposite direction under the drive of the corresponding second motor to clamp and position the packaging box. The packaging box is then conveyed forward in the clamped state.

[0021] A U-shaped bracket 700 is provided above the conveyor table 100. The bracket 700 spans across the conveyor table 100 and is equipped with an adjustable limiting mechanism. This mechanism includes a pair of parallel limiting baffles 610, a guide rail 620 horizontally arranged along the width direction of the conveyor table 100, two sliders 630 slidably mounted on the guide rail 620, a bidirectional screw 640, and a servo motor 650. The two limiting baffles 610 are vertically fixed to the corresponding sliders 630, and their shape is "T"-shaped to better fit and guide the sides of the packaging box. A threaded sleeve 611 is fixed to the upper part of each limiting baffle 610. The bidirectional screw 640 passes through the inner holes of the two threaded sleeves 611 and forms a threaded drive connection with them. The left and right ends of the thread of the bidirectional screw 640 have opposite directions of rotation. The servo motor 650 is also mounted on the bracket 700, and its output shaft is driven by one end of the bidirectional screw 640 via a belt (not shown in the figure).

[0022] Working Process: When it is necessary to change to a packaging box of different widths, the control system issues a command to start the servo motor 650. The servo motor 650 drives the bidirectional screw 640 to rotate forward or backward. Since the two ends of the bidirectional screw 640 have opposite thread directions, when the bidirectional screw 640 rotates, it drives the two threaded sleeves 611, along with the slider 630 and the connected limit baffles 610, to move towards or away from each other along the guide rail 620. In this way, the gap between the two limit baffles 610 can be quickly and accurately changed to match the width of the new packaging box. Subsequently, the packaging box is placed on the conveyor table 100 and driven forward by the push belt 310. At the same time, it is precisely positioned by the limit baffles 610 on both sides and stabilized by the positioning belt 320 in the middle, thus completing an efficient and accurate conveying process and ensuring that the packaging box is assembled in a stable state when passing through each workstation.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
