Description

Technical Field

[0001] This utility model relates to the field of mask production technology, specifically to a shrinkage angle flattening device for packaging boxes. Background Technology

[0002] During the mask production process, the masks processed on the production line are inspected and qualified before being packed into mask packaging boxes. The boxes full of masks are then neatly arranged in a matrix and placed in turnover boxes for storage and turnover.

[0003] During the heat shrink film wrapping process, the packaging boxes (products) in the turnover box are picked up and placed on the conveyor belt of the production line. The conveyor belt transports the packaging boxes to the heat shrink film packaging station, where the wrapping equipment wraps the packaging boxes with heat shrink film. Then, the conveyor belt transports the packaging boxes to the next process position.

[0004] The inventors of this application discovered that after a packaging box is covered with shrink film, the uneven shrinkage force of the shrink film causes sharp corners (shrinkage corners) to form at both ends of the horizontal seal (both ends along the length of the packaging box). As the film cools down, these sharp corners become harder, posing a risk of scratching people. Manually smoothing these sharp corners (shrinkage corners) is not only labor-intensive and inefficient, but also prone to omissions. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] The technical solution of this utility model will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0049] As described in the background section of this application, packaging boxes filled with masks on the production line need to be covered with heat-shrink film, and then the conveyor belt transports the packaging boxes to the next process packing station.

[0050] The inventors of this application discovered that after a packaging box is covered with shrink film, the uneven shrinkage force of the shrink film causes sharp corners to form at both ends of the horizontal seal (both ends along the length of the packaging box). As the film cools down, these sharp corners become harder, posing a risk of scratching people. Manually smoothing these sharp corners is not only labor-intensive and inefficient, but also prone to omissions and is not suitable for automated production.

[0051] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0052] Figure 1 This is a top view schematic diagram of the shrinkage angle flattening device for packaging boxes in an embodiment of this utility model. Figure 2 As described in the embodiments of this utility model Figure 1 A magnified view of a portion of the image. Figure 3 This is a three-dimensional schematic diagram of the contraction angle flattening device in an embodiment of the present invention. Figure 4 As described in the embodiments of this utility model Figure 3 A magnified view of a portion of the image. Figure 5 As described in the embodiments of this utility model Figure 3 Another enlarged view of a part of it, Figure 6 As described in the embodiments of this utility model Figure 3 Enlarged view of point A in the image.

[0053] like Figures 1 to 6 As shown, the shrinkage angle flattening device for packaging boxes in this embodiment includes: a machine base 1, a feeding conveyor belt 2, a discharging conveyor belt 3, a servo drive mechanism, and a pressing mechanism.

[0054] The feeding conveyor belt 2 and the discharging conveyor belt 3 are arranged parallel to each other on the machine base 1. The end of the feeding conveyor belt 2 is adjacent to the beginning of the discharging conveyor belt 3, and there is a distance between the end of the feeding conveyor belt 2 and the beginning of the discharging conveyor belt 3. Both the feeding conveyor belt 2 and the discharging conveyor belt 3 are used to transport packaging boxes.

[0055] The machine 1 is provided with a first baffle 11 at the end of the feeding conveyor belt 2. The first baffle 11 blocks the packaging box 100 to restrict the movement of the packaging box 100 on the feeding conveyor belt 2.

[0056] The machine 1 is equipped with a pinching station 101, which is located in the gap between the end of the feeding conveyor belt 2 and the beginning of the discharging conveyor belt 3.

[0057] The machine 1 is equipped with a transfer channel, which is formed by multiple side plates. The transfer channel connects the corner pinching station 101 of the machine 1 with the end of the feeding conveyor belt 2 and is used for the passage of packaging boxes.

[0058] The servo drive mechanism and the extrusion mechanism are respectively set on the machine base 1. The servo drive mechanism is used to push the packaging box 100 at the end of the feeding conveyor belt 2 along the flow channel to the corner pinching station 101. At the corner pinching station 101 of the machine base 1, the extrusion mechanism clamps and extrudes the packaging box from both sides of the packaging box 100 along its length, pinching the shrink film corners of the packaging box flat so that there are no sharp corners of shrink film on the packaging box. Then, the servo drive mechanism pushes the flattened packaging box 100 on the corner pinching station 101 to the discharge conveyor belt 3, and the discharge conveyor belt 3 transports the packaging box to the next process packing station.

[0059] As can be seen from the above, the shrink corner flattening device for packaging boxes in this embodiment comprises a machine base, a feeding conveyor belt, a discharging conveyor belt, a servo drive mechanism, and a pressing mechanism. The feeding and discharging conveyor belts are arranged parallel to each other on the machine base, which has a corner pinching station connected to the end of the feeding conveyor belt via a transfer channel. The servo drive mechanism and the pressing mechanism are located on the machine base. This shrink corner flattening device for packaging boxes is controlled by a PLC controller. When the packaging box covered with shrink film is conveyed to the end of the feeding conveyor belt, the servo drive mechanism pushes the packaging box along the transfer channel to the corner pinching station. At the corner pinching station, the pressing mechanism clamps and presses both sides of the packaging box, flattening the shrink film corners. Then, the servo drive mechanism pushes the packaging box onto the discharging conveyor belt, which transports the packaging box to the next process's packing station. By changing the position of the packaging box through the servo drive mechanism and flattening the shrink film corners through the pressing mechanism, production efficiency is improved, and packaging boxes (products) without pinched corners are prevented from flowing into the next process.

[0060] Optionally, the shrinkage angle flattening device for packaging boxes in this embodiment includes a servo drive mechanism comprising: a first servo mechanism 41, a second servo mechanism 42, a third servo mechanism 43, and a fourth servo mechanism 44.

[0061] Each servo mechanism of the servo drive mechanism is set on the machine base 1.

[0062] The transfer channels on machine 1 are right-angled and include: a first transfer channel 121 and a second transfer channel 122.

[0063] The first transfer channel 121 and the second transfer channel 122 are arranged perpendicularly to each other. The first transfer channel 121 and the second transfer channel 122 are connected. The other end of the first transfer channel 121 is connected to the end of the feeding conveyor belt 2, and the other end of the second transfer channel 122 is connected to the corner pinching station 101.

[0064] The extrusion mechanism includes a fixed plate 51 and a movable plate 52.

[0065] The fixed plate 51 is set at the corner pinching station 101 of the machine base 1, and the movable plate 52 is set on the second servo mechanism 42.

[0066] When the packaging box moves to the end of the feeding conveyor belt 2 and is blocked by the first baffle 11, the first servo mechanism 41 pushes the packaging box 100 on the feeding conveyor belt 2 along the first transfer channel 121 into the second transfer channel 122. Then, the second servo mechanism 42 pushes the packaging box along the second transfer channel 122 to the corner pinching station 101 of the machine 1, where it contacts and abuts against the fixed plate 51. At the same time, the movable plate 52 on the second servo mechanism 42 cooperates with the fixed plate 51 to clamp and squeeze the packaging box 100 from both sides along the length of the packaging box, flattening the shrink film corners of the packaging box (pinching).

[0067] After the packaging box is squeezed for a certain period of time, the third servo mechanism 43 transports the packaging box on the pinching station 101 to the head end of the discharge conveyor belt 3.

[0068] Finally, the fourth servo mechanism 44 pushes the packaging box onto the discharge conveyor belt 3, which then transports the packaging box to the next process's packing station.

[0069] Furthermore, in this embodiment, the shrinkage angle flattening device for packaging boxes, the first servo mechanism 41, the second servo mechanism 42 and the fourth servo mechanism 44, all include: a servo electric cylinder 401 and a pusher frame 402.

[0070] One side of the pusher 402 is mounted on the servo cylinder 401. The servo cylinder 401 drives the pusher 402 to move. When the pusher 402 moves, it is used to push the packaging box 100.

[0071] The movable plate 52 of the extrusion mechanism is mounted on the pusher 402 of the second servo mechanism 42, and is used to push the packaging box and to cooperate with the fixed plate 51 to clamp and extrude the packaging box.

[0072] The third servo mechanism 43 includes: a servo motor 431 and a conveyor chain plate 432.

[0073] The servo motor 431 is connected to the conveyor chain plate 432 through a transmission assembly, and the servo motor 431 drives the conveyor chain plate 432 to rotate.

[0074] The corner pinching station 101 of the machine tool 1 is set on the conveyor chain plate 432 of the third servo mechanism 43. When the packaging box is pushed to the corner pinching station 101, it is located on the conveyor chain plate 432 of the third servo mechanism 43. After the corner of the packaging box is pinched and flattened, the conveyor chain plate 432 conveys the packaging box to the head end of the discharge conveyor belt 3.

[0075] Furthermore, in this embodiment, the shrink angle flattening device for packaging boxes has multiple partitions 4321 on the conveyor chain plate 432 of the third servo mechanism 43.

[0076] When the packaging box 100 is pushed to the corner pinching station 101 (on the conveyor chain plate 432), it is located between two adjacent partitions 4321. The partitions 4321 restrict the movement and swaying of the packaging box, so that the packaging box remains stable during corner pinching and conveying.

[0077] Furthermore, in this embodiment, the shrinkage angle flattening device for the packaging box is provided with rubber pads 501 on the sides of both the fixed plate 51 and the movable plate 52. When the packaging box is squeezed, the rubber pads 501 on the fixed plate 51 and the movable plate 52 contact and abut against the packaging box 100.

[0078] Optionally, the shrinkage angle flattening device for packaging boxes in this embodiment further includes: a photoelectric sensor 6.

[0079] The photoelectric sensor 6 is mounted on the frame of the feeding conveyor belt 2 and is located at the end of the feeding conveyor belt 2.

[0080] The photoelectric sensor 6 is electrically connected to the controller. When the photoelectric sensor 6 senses that the packaging box 100 has reached the preset position (the end of the feeding conveyor belt), it sends a signal to the controller. The controller controls the servo drive mechanism to push the packaging box to the corner pinching station 101 of the machine for flattening and pinching the corners.

[0081] Optionally, the shrinkage angle flattening device for packaging boxes in this embodiment further includes a second baffle 13.

[0082] Two second baffles 13 are set on the frame of the feeding conveyor belt 2, and a feeding channel is formed between the two second baffles 13.

[0083] When the feeding conveyor belt 2 conveys the packaging box, the packaging box moves along the feeding channel between the second baffles 13.

[0084] Furthermore, the shrinkage angle flattening device for packaging boxes in this embodiment also includes a steering mechanism 7.

[0085] The steering mechanism 7 includes a support rod 71 and a roller 72.

[0086] One end of the support rod 71 is set on the frame of the discharge conveyor belt 3, and the roller 72 is rotatably set on the other end of the support rod 71. When the roller 72 contacts and abuts against one side of the packaging box 100, the packaging box 100 rotates 90°.

[0087] In this embodiment, the packaging box is pushed vertically onto the discharge conveyor belt. When the discharge conveyor belt moves the packaging box, one side of the packaging box contacts and abuts against the roller. The roller blocks the packaging box, causing it to turn 90°. The packaging box changes from vertical to horizontal and is sent to the next process's packing station to meet the packing requirements.

[0088] Furthermore, in this embodiment, the shrinkage angle flattening device for packaging boxes, the steering mechanism 7 also includes: a fixing seat 73 and a locking bolt.

[0089] The fixed seat 73 is set on the frame of the discharge conveyor belt 3. The support rod 71 is slidably inserted into the mounting hole of the fixed seat 73. The locking bolt (not shown in the figure) is engaged in the threaded hole of the fixed seat 73. When the locking bolt is tightened, it abuts against the support rod 71 to fix the support rod 71 on the fixed seat 73.

[0090] The working process of the shrinkage angle flattening device for packaging boxes of this utility model is as follows:

[0091] After the packaging box is covered with heat-shrink film, it is conveyed to the end of the feeding conveyor belt. Once the photoelectric sensor detects the packaging box, the first servo mechanism's pusher pushes it to the second transfer channel. Then, the second servo mechanism's pusher pushes the packaging box to the corner-pinching station (conveyor chain). Simultaneously, the second servo mechanism drives the movable plate and fixed plate to squeeze the packaging box. After squeezing for a certain period, the second servo mechanism drives the movable plate to retract, and the third servo mechanism's conveyor chain conveys the packaging box to the beginning of the discharge conveyor belt. The fourth servo mechanism's pusher pushes the packaging box from the conveyor chain onto the discharge conveyor belt. After a 90° turn, the packaging box is conveyed to the next process's packing station.

[0092] In this utility model, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0093] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
