Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to a positioning device for a window pasting machine. Background Technology

[0002] A window film applicator is a device used for applying film to windowed cardboard boxes, also known as a cardboard box window film applicator. In the packaging industry, it is used to apply film to various windowed gift boxes, cosmetic boxes, and tissue boxes, etc., so that a layer of transparent plastic film is applied to the window of the packaging box, allowing consumers to see the contents of the packaging box directly and increasing their willingness to buy. In the current use of window film applicators, the material feeding process is mostly done manually. When feeding the window film applicator, due to the different operating skills of each person, it is easy to place the material crookedly. Once the angle of the material is deviated, the window film applicator will use this crooked initial position as the reference when performing the film application, which will lead to the problem of misaligned application. This not only wastes film material and increases production costs, but may also result in finished products that do not meet quality requirements. Utility Model Content

[0003] In order to overcome the above-mentioned technical problems, this utility model provides a positioning device for a window patching machine that can accurately position cardboard.

[0004] The technical implementation scheme of this utility model is as follows: a positioning device for a window pasting machine, including a base, a support frame, a conveyor belt, a motor, a belt, a rotating shaft, a limiting plate, a sliding rod, a screw, and a guiding mechanism. The support frame is fixedly connected to the base, and the motor is fixedly connected to the right side of the support frame. The front and rear ends of the support frame are rotatably connected to the rotating shaft. A belt is provided between the motor output shaft and the front rotating shaft through a pulley. The conveyor belt is wound between the two rotating shafts, and the conveyor belt is arranged with the front lower and the rear higher. Two sliding rods are fixedly connected to the support frame, and two limiting plates are symmetrically slidably connected to the two sliding rods. The limiting plates are located above the conveyor belt. A screw is rotatably connected to the support frame, and the screw is located between the two sliding rods. The middle part of the two limiting plates is threadedly connected to the screw, and the two ends of the screw have opposite threads. A guiding mechanism is installed on the two limiting plates. The guiding mechanism is used to guide the cardboard into the space between the two limiting plates.

[0005] Furthermore, the guiding mechanism includes a first telescopic plate, a second telescopic plate, a slider, and a hinge. The rear ends of both limiting plates are rotatably connected to the first telescopic plate, and the rear ends of the first telescopic plate are fixedly connected to the slider. The inner rear part of the support frame is fixedly connected to the hinge. The second telescopic plate is rotatably connected to the support frame through the hinge. A sliding groove is provided on the second telescopic plate, and the first telescopic plate and the second telescopic plate on the same side are slidably connected through the slider and the sliding groove.

[0006] Furthermore, it also includes connecting rods, pressing wheels, mounting brackets, and pressing rollers. Connecting rods are fixedly connected to the front side of the base and the middle of the support frame. Pressing wheels are connected to the middle of the two connecting rods and the two sliding rods. The mounting bracket is fixedly connected to the upper rear part of the support frame, and the pressing roller is rotatably connected to the bottom of the mounting bracket.

[0007] Furthermore, it also includes a guide plate, which is fixedly connected to the rear side of the mounting bracket.

[0008] Furthermore, it also includes an anti-slip sleeve, which is fixedly connected to the right side of the screw.

[0009] Furthermore, it also includes a dustproof net, which is fixedly connected to the top of the support frame and is located above the limiting plate.

[0010] This utility model has the following advantages: 1. The conveyor belt is driven by a motor to transport the cardboard forward. The screw is rotated to make the two limiting plates move towards or away from each other on the sliding rod, so that the cardboard is kept in a relatively fixed position on the conveyor belt. This ensures that the subsequent window covering machine can always perform the film covering operation at an accurate angle, effectively avoiding the problem of misaligned covering due to the material being placed crookedly, and ensuring the quality of film covering.

[0011] 2. By moving the limiting block, the first and second telescopic plates move and rotate accordingly, thereby minimizing the positional deviation of the cardboard, improving the final film positioning accuracy, and ensuring the film application quality.

[0012] 3. Pressing rollers and pressing wheels are used to press the cardboard to prevent it from moving up and down during transport, thereby improving the accuracy of positioning. Attached Figure Description

Detailed Implementation

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Example: A positioning device for a window patching machine, such as Figure 1-3 As shown, the system includes a base 1, a support frame 101, a conveyor belt 2, a motor 3, a belt 4, a rotating shaft 5, a limiting plate 6, sliding rods 7, screws 8, a first telescopic plate 9, a second telescopic plate 901, a slider 10, and a hinge 11. The support frame 101 is fixedly connected to the base 1. The motor 3 is fixedly connected to the right side of the support frame 101. The rotating shafts 5 are rotatably connected to both the front and rear ends of the support frame 101. A belt 4 is provided between the output shaft of the motor 3 and the front rotating shaft 5 via a pulley. The conveyor belt 2 is wound between the two rotating shafts 5, and the conveyor belt 2 is arranged with the front lower than the rear. Two sliding rods 7 are fixedly connected to the support frame 101, and two limiting plates are symmetrically slidably connected to the two sliding rods 7. 6. The limiting plate 6 is located above the conveyor belt 2. The screw 8 is rotatably connected to the support frame 101. The screw 8 is located between the two sliding rods 7. The middle part of the two limiting plates 6 is threadedly connected to the screw 8. The threads at both ends of the screw 8 are in opposite directions. The rear ends of the two limiting plates 6 are rotatably connected to the first telescopic plate 9. The rear end of the first telescopic plate 9 is fixedly connected to the slider 10. The hinge 11 is fixedly connected to the inner rear part of the support frame 101. The second telescopic plate 901 is rotatably connected to the support frame 101 through the hinge 11. The second telescopic plate 901 is provided with a sliding groove. The first telescopic plate 9 and the second telescopic plate 901 on the same side are slidably connected to the sliding groove through the slider 10.

[0019] like Figure 1-2 As shown, it also includes a connecting rod 12, a pressing wheel 13, a mounting frame 14, and a pressing roller 15. The connecting rod 12 is fixedly connected to the front side of the base 1 and the middle part of the support frame 101. The pressing wheel 13 is connected to the middle part of the two connecting rods 12 and the two sliding rods 7. The mounting frame 14 is fixedly connected to the upper rear part of the support frame 101. The pressing roller 15 is rotatably connected to the bottom of the mounting frame 14.

[0020] like Figure 1-2 As shown, it also includes a guide plate 16, which is fixedly connected to the rear side of the mounting bracket 14.

[0021] like Figure 1 As shown, it also includes an anti-slip sleeve 17, which is fixedly connected to the right side of the screw 8.

[0022] like Figure 1 As shown, it also includes a dustproof net 18, which is fixedly connected to the top of the support frame 101. The dustproof net 18 is located above the limiting plate 6. The dustproof net 18 can prevent dust and other impurities from falling into the interior of the positioning device and affecting its normal operation and positioning accuracy.

[0023] When using this device, the limiting plates 6 need to be initially adjusted according to the size of the cardboard to be laminated. This primarily involves roughly determining the distance between the limiting plates 6 to accommodate the width of the cardboard. The operator holds the anti-slip sleeve 17 on the right side of the screw 8 to facilitate rotation and prevent hand slippage. Since the limiting plates 6 are threaded onto the screw 8, rotation of the screw 8 causes the two limiting plates 6 to move in opposite directions on the sliding rod 7, thereby adjusting the distance between the two limiting plates 6 to match the width of the cardboard to be laminated. The guide plate 16 can... The cardboard is guided onto the conveyor belt 2, ensuring its initial position is relatively regular for easy subsequent conveying and positioning. The cardboard to be laminated is placed on the conveyor belt 2. Then, the motor 3 is started, driving the rotating shaft 5 at its front end via the belt 4. This drives the conveyor belt 2, which is wound around the rotating shaft 5, to begin operating. The conveyor belt 2 transports the placed cardboard forward, maintaining a relatively fixed position on the conveyor belt 2. This creates favorable conditions for subsequent precise positioning, minimizing cardboard positional deviation, improving the final lamination positioning accuracy, and ensuring successful lamination. To improve quality, during the cardboard conveying process, the pressing wheel 13 and pressing roller 15 installed on the middle of the connecting rod 12 and the sliding rod 7 press the cardboard to prevent it from moving up and down during conveying, further improving positioning accuracy. When the cardboard moves forward with the conveyor belt 2 to the area of ​​the limiting plate 6, since the rear end of the limiting plate 6 is connected to the first telescopic plate 9, and the rear end of the first telescopic plate 9 is comb-shaped and slides with the second telescopic plate 901, which is also comb-shaped, when the position of the limiting plate 6 changes due to the adjustment of the screw 8, the first telescopic plate 9 and the second telescopic plate 901 will move together. Due to the extension, retraction, and rotation of the first telescopic plate 9, the slider 10 will move through the groove on the second telescopic plate 901. Because their comb-like structures cooperate with each other, they can make flexible and precise length adjustments in the front and back directions of the cardboard, further positioning the cardboard and ensuring that the cardboard maintains a stable position during the conveying process. This ensures that the subsequent window pasting machine can always perform the window pasting operation at the correct angle and orientation, thereby effectively avoiding the problem of pasting misalignment due to the material being placed crookedly, ensuring the quality of the pasting, improving production efficiency and the overall qualification rate of the product. After the cardboard is positioned, the cardboard will be conveyed to the pasting area to complete the window pasting process.
