Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging box film coating mechanism. Background Technology

[0002] In the automated lamination process for packaging boxes, the boxes are conveyed by a conveyor belt to the lamination unit for lamination. To ensure lamination quality, the boxes must maintain a precise preset position and orientation when entering the lamination station. However, during the conveying process, the boxes are prone to shifting or deflecting, so they must be aligned and corrected before entering the lamination unit.

[0003] Currently, the commonly used solution in the industry is to install photoelectric sensors along the conveyor belt upstream of the laminating station to detect the arrival of packaging boxes. When the sensor detects a packaging box, it sends a signal to the control system, which then activates the downstream correction actuator (such as a cylinder push rod, swing arm, etc.) to correct the position of the packaging box.

[0004] However, the applicant has found that the prior art has at least the following problems: The detection accuracy of photoelectric sensors is easily affected by the production environment. In factories such as paper processing, building materials production, and food and feed manufacturing, the air is filled with a large amount of paper scraps, raw material dust, or food dust. This dust will continuously adhere to the transmitting and receiving lenses of the sensor, forming a contamination layer, which will lead to signal weakening or even failure. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a packaging box coating mechanism to solve the problem that dust will continuously adhere to the transmitting and receiving lenses of the sensor, forming a contamination layer, which will lead to signal weakening or even failure.

[0006] To achieve the above objectives, this utility model provides a packaging box laminating mechanism, including a base, a conveyor belt mounted on the base, a gap in the middle of the conveyor belt, a detection component mounted below the gap, a correction component mounted behind the detection component, and a laminating box mounted behind the correction component. The detection component includes a mounting box mounted between the base and the mounting box, with a moving groove adapted to the gap. A detection column is mounted in the moving groove, and the detection column is connected to a mounting shaft. The mounting shaft is fixedly mounted on the inner wall of the mounting box to keep the detection column vertical. The top of the detection column extends out from the gap. A photoelectric seat is mounted on the bottom surface inside the mounting box, and a photoelectric switch is mounted on the photoelectric seat. The photoelectric switch monitors the position of the detection column. When the position of the detection column shifts, the correction component is automatically activated to correct the packaging box.

[0007] Optionally, a guide groove is provided on the wall of the movable groove, and a push block is adapted to be installed in the guide groove. One end of the push block is connected to the inner wall of the movable groove by a folded fabric. Guide blocks adapted to the guide groove are provided on both sides of the push block. A connecting rod is connected to the push block, and a guide seat is adapted to be connected to the connecting rod. The guide seat is fixedly installed on the inner wall of the mounting box. A connecting rope is connected to the connecting rod. A ring is also installed on the inner wall of the mounting box. The end of the connecting rope passes through the ring and is connected to a counterweight.

[0008] Optionally, an anti-shake guide tube is installed on the bottom surface inside the mounting box, and a counterweight is adapted to be installed in the anti-shake guide tube.

[0009] Optionally, the detection column has vertical upper and lower grooves on the other side relative to the push block. A vertical slider is adapted to be installed in the upper and lower grooves. An insertion block is connected to the vertical slider. The two sides of the insertion block are adapted to be inserted into the moving groove. A dustproof cloth is connected to the insertion block. The dustproof cloth is connected to the other end of the inner wall of the moving groove.

[0010] Optionally, the correction assembly includes mounting seats fixedly installed on both sides of the base, a bidirectional lead screw installed between the two mounting seats, a lead screw motor electrically connected to the bidirectional lead screw, two movable seats adapted to be installed on the bidirectional lead screw, a guide rod installed between the two mounting seats, the guide rod guides the movable seats, and a correction plate is connected to the movable seats.

[0011] Optionally, a connecting column is installed on the movable seat, one end of the connecting column is connected to a connecting base, and the other end of the connecting column is connected to a straightening plate. A buffer spring is sleeved on the connecting column between the straightening plate and the movable seat.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a packaging box laminating mechanism. The packaging box is conveyed by a conveyor belt. When the packaging box reaches the position of the detection column, it pushes the detection column, causing it to rotate. The lower half of the detection column moves away from the photoelectric switch. At this time, the photoelectric switch is electrically connected to the correction component, which corrects the packaging box and straightens it. After the packaging box is straightened, it is sent by the conveyor belt into the laminating box for lamination. Since the photoelectric switch is installed in a relatively sealed installation box, the influence of dust is greatly reduced, which can effectively improve the detection accuracy.

[0016] 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 specific embodiments.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] like Figures 1 to 5As shown, a specific embodiment of this utility model provides a packaging box laminating mechanism, including a base 101, a conveyor belt 102 mounted on the base 101, a gap 103 in the middle of the conveyor belt 102, a detection component mounted below the gap 103, a correction component mounted behind the detection component, and a laminating box 301 mounted behind the correction component. The detection component includes a mounting box 202 mounted between the base 101 and the mounting box 202, which has a moving groove 203 adapted to the gap 103. 3. A detection column 201 is installed in the box, and the detection column 201 is connected to a mounting shaft 220. The mounting shaft 220 is fixedly installed on the inner wall of the mounting box 202 to keep the detection column 201 vertical. The top of the detection column 201 extends out from the gap 103. A photoelectric seat 216 is installed on the bottom surface inside the mounting box 202. A photoelectric switch 218 is installed on the photoelectric seat 216. The photoelectric switch 218 monitors the position of the detection column 201. When the position of the detection column 201 is offset, the self-starting correction component corrects the packaging box.

[0019] During the lamination process, the packaging box is conveyed by the conveyor belt 102. When the packaging box reaches the position of the detection column 201, it pushes the detection column 201, causing it to rotate. The lower half of the detection column 201 moves away from the photoelectric switch 218. At this time, the photoelectric switch 218 is electrically connected to the correction component, which corrects the packaging box and straightens it. After straightening, the packaging box is sent by the conveyor belt 102 into the lamination box 301 for lamination. Since the photoelectric switch 218 is installed in the relatively sealed mounting box 202, the influence of dust is greatly reduced, which can effectively improve the detection accuracy.

[0020] In some optional specific embodiments, such as Figures 1 to 5 As shown, a guide groove 204 is provided on the wall of the moving groove 203. A push block 206 is adapted to be installed in the guide groove 204. One end of the push block 206 is connected to the inner wall of the moving groove 203 by a folded fabric 205. Guide blocks 207 adapted to the guide groove 204 are provided on both sides of the push block 206. A connecting rod 212 is connected to the push block 206. A guide seat 213 is adapted to be connected to the connecting rod 212. The guide seat 213 is fixedly installed on the inner wall of the mounting box 202. A connecting rope 214 is connected to the connecting rod 212. A ring 219 is also installed on the inner wall of the mounting box 202. The end of the connecting rope 214 passes through the ring 219 and is connected to a counterweight 217. When the detection column 201 is pushed, it will push the push block 206 to move, causing the folded fabric 205 to fold. After the packaging box is removed, the counterweight 217 will pull the push block 206 back to its original position and push the detection column 201 to reset, causing the folded fabric 205 to unfold for dust protection. At the same time, the counterweight 217 provides a more constant pulling force on the push block 206 compared to a spring.

[0021] In some optional specific embodiments, such as Figures 1 to 5 As shown, a stabilizing guide tube 215 is installed on the bottom surface inside the mounting box 202, and a counterweight 217 is adapted to be installed in the stabilizing guide tube 215.

[0022] In some optional embodiments, as shown in the figure, the detection column 201 has vertical upper and lower grooves 208 on the other side opposite to the push block 206. A vertical slider 209 is adapted to be installed in the upper and lower grooves 208. The vertical slider 209 is connected to an insertion block 210. The two sides of the insertion block 210 are adapted to be inserted into the moving groove 203. The insertion block 210 is connected to a dustproof cloth 211, which is connected to the other end of the inner wall of the moving groove 203. When the detection column 201 swings, it pulls the insertion block 210 to move, unfolding the dustproof cloth 211.

[0023] In some optional embodiments, as shown in the figure, the correction assembly includes mounting seats 104 fixedly installed on both sides of the base 101. A bidirectional lead screw 106 is installed between the two mounting seats 104. The bidirectional lead screw 106 is electrically connected to a lead screw motor 105. Two movable seats 108 are also adapted to be installed on the bidirectional lead screw 106. A guide rod 107 is also installed between the two mounting seats 104, guiding the movable seats 108. A correction plate 112 is connected to the movable seats 108. The lead screw motor 105 drives the bidirectional lead screw 106 to rotate, driving the movable seats 108 to move towards or away from each other. The correction plate 112 clamps and corrects the mounting box.

[0024] In some optional embodiments, as shown in the figure, a connecting post 111 is mounted on the movable base 108. One end of the connecting post 111 is connected to a connecting seat 109, and the other end of the connecting post 111 is connected to a straightening plate 112. A buffer spring 110 is sleeved on the connecting post 111 between the straightening plate 112 and the movable base 108. The buffer spring 110 provides cushioning when straightening the packaging box.

[0025] The working principle of this utility model is as follows: During the packaging box lamination operation, the packaging box is conveyed by the conveyor belt 102. When the packaging box reaches the position of the detection column 201, it pushes the detection column 201, causing it to rotate. The lower half of the detection column 201 moves away from the photoelectric switch 218. At this time, the photoelectric switch 218 is electrically connected to the correction component, which corrects the packaging box and straightens it. After straightening, the packaging box is sent by the conveyor belt 102 into the lamination box 301 for lamination. Since the photoelectric switch 218 is installed in the relatively sealed installation box 202, the influence of dust is greatly reduced, which can effectively improve the detection accuracy.
