Description

Technical Field

[0001] This utility model relates to the field of case packing machine technology, and in particular to an automatic case packing machine for eyeglasses. Background Technology

[0002] Boxes, as packaging containers, are typically used for transport packaging and belong to outer packaging. Boxes and containers are similar in shape; conventionally, smaller ones are called boxes and larger ones are called cartons, and there is no clear boundary between them. However, boxes have weaker structural strength and require additional measures (such as linings or partitions inside the box) to enhance internal positioning and cushioning and vibration isolation. Cartoning technology refers to the technique of packing pre-packaged products into cartons in a certain way to prevent damage during transportation and facilitate storage and transport, and then sealing the carton opening.

[0003] For example, the Chinese utility model patent application CN222833122U describes an automatic packaging device for printers. It can easily pick up printers from the finished product placement table, pack them into boxes, and then automatically seal the boxes. After sealing, the boxes are automatically stacked. However, this structure still has the following significant drawbacks:

[0004] 1. When the device is not in use, the cutting structure on the carton sealing machine is easily scratched or damaged by accidental contact by the user;

[0005] 2. When sealing a carton, the pressure force exerted by the pressure rollers on the tape and the carton is related to the tape's adhesiveness. If a user purchases multiple batches of tape at the same time, the adhesiveness of each batch often fluctuates. Traditional carton sealing machines have poor adaptability to tapes with different adhesive strengths, which can easily lead to the tape not adhering firmly to the seal.

[0006] 3. When the box passes through the sealing machine, it is easy for the box to get stuck or unable to pass through. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art.

[0008] This application provides an automatic eyeglass case packing machine, including a roller conveyor, a stacking structure, a clamping structure, and a case sealing structure. The case sealing structure includes a side plate fixedly installed on the roller conveyor, a cutter holder rotatably installed on the side plate, a cutter and a lifting block fixedly installed on the cutter holder; the cutter holder is provided with a protective component, which stores the cutter when not in use.

[0009] Furthermore, the protective assembly includes a slide rod, a protective sleeve, and a protective sleeve lifting block. The cutter holder is provided with a slide rod, and a protective sleeve is slidably installed on the slide rod. A protective groove is provided inside the protective sleeve, and the cutter is located in the protective groove. A spring is sleeved on the slide rod, and a protective sleeve lifting block is fixed on the protective sleeve.

[0010] Furthermore, the length of the protective sleeve lifting block is longer than that of the lifting block itself.

[0011] Furthermore, the protective assembly also includes a top block, a threaded post at the top of the slide rod, a threaded groove on the top block that is threaded to engage with the threaded post, the bottom end of the top block abutting against the top of the slide rod, one end of the spring pressing against the top block, and the other end pressing against the protective sleeve.

[0012] Furthermore, a pair of hinge shafts are fixedly provided on the side plate, and a first connecting plate and a second connecting plate are rotatably mounted on the pair of hinge shafts respectively. A rotating shaft is fixedly provided on both the first connecting plate and the second connecting plate, and a front pressure roller and a rear pressure roller are rotatably mounted on the corresponding rotating shafts respectively. The front pressure roller and the rear pressure roller can be lifted synchronously through the pressure roller transmission structure. A first elastic element and an adjustable second elastic element are respectively provided on the first connecting plate and the second connecting plate.

[0013] Furthermore, the second elastic element includes a second torsion spring, an adjusting knob, and a screw. The second connecting plate is provided with a mounting groove and a threaded hole that is threaded to the screw. One end of the screw extends into the mounting groove, and the other end extends out of the second connecting plate and is fixedly connected to the adjusting knob. The side plate is provided with a second torsion spring hole. The second torsion spring is sleeved on a hinge shaft that is rotatably engaged with the second connecting plate. One end of the second torsion spring passes through the second torsion spring hole, and the other end abuts against the screw.

[0014] Furthermore, the first elastic element includes a first torsion spring, and both the side plate and the first connecting plate are provided with first torsion spring holes. The first torsion spring is sleeved on a hinge shaft that rotatably engages with the first connecting plate, and both ends of the first torsion spring pass through the corresponding first torsion spring holes.

[0015] Furthermore, the pressure roller transmission structure includes a lever, a first connecting cylinder, a second connecting cylinder and a cylindrical groove. The lever is rotatably mounted on the side plate via a hinge shaft. The first connecting cylinder and the second connecting cylinder are fixed at both ends of the lever, and cylindrical grooves that slide in cooperation with the first connecting cylinder and the second connecting cylinder are distributed on the first connecting plate and the second connecting plate.

[0016] The distance between the first connecting cylinder and the corresponding hinge of the lever must be greater than the distance between the second connecting cylinder and the corresponding hinge of the lever.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting up protective components, the cutter can be stored in the protective slot, thereby preventing users from accidentally touching the cutter and causing injury.

[0019] 2. By setting the second elastic element, the pressure of the front pressure roller and the rear pressure roller pressing the tape onto the box seal can be adjusted to provide sufficient pressure to firmly stick the tape to the box seal.

[0020] 3. Through the setting of the pressure roller transmission structure, the lever is a force-saving lever, which makes it easier for the front pressure roller and the rear pressure roller to be lifted synchronously during the movement of the box, and the box is less likely to get stuck.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The automatic eyeglass packing machine provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0032] Example 1:

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, this application embodiment provides an automatic eyeglass case packing machine, including a roller conveyor 1, a stacking structure 2, a clamping structure 3, and a sealing structure 4. The sealing structure 4 includes a side plate 41 fixedly installed on the roller conveyor 1, a cutter holder 42 rotatably installed on the side plate 41, a cutter 43 fixedly installed on the cutter holder 42, and a lifting block 44. The cutter holder 42 is provided with a protective component 45, which stores the cutter 43 when not in use.

[0034] Furthermore, the protective component 45 includes a slide rod 451, a protective sleeve 452, and a protective sleeve lifting block 453. The cutter holder 42 is provided with a slide rod 451, and the protective sleeve 452 is slidably installed on the slide rod 451. The protective sleeve 452 is provided with a protective groove, and the cutter 43 is located in the protective groove. A spring 454 is sleeved on the slide rod 451, and the protective sleeve lifting block 453 is fixed on the protective sleeve 452.

[0035] Furthermore, the length of the protective sleeve lifting block 453 is longer than that of the lifting block 44.

[0036] Furthermore, the protective component 45 also includes a top block 455, a threaded post 456 at the top of the slide rod 451, a threaded groove on the top block 455 that is threadedly engaged with the threaded post 456, the bottom end of the top block 455 abutting against the top end of the slide rod 451, one end of the spring 454 pressing against the top block 455, and the other end pressing against the protective sleeve 452.

[0037] In this embodiment of the application, due to the above-mentioned structure, a sealing structure 4 is fixedly connected to the top center of the roller conveyor 1, a stacking structure 2 is provided on the right side of the roller conveyor 1, and a clamping mechanism 3 is provided on the left side of the roller conveyor 1. During use, the box is placed on the roller conveyor 1, and the box is blocked by the blocking mechanism on the roller conveyor 1 and can only slide along the center line of the roller conveyor 1. When the box moves to the bottom of the clamping mechanism 3, the clamping mechanism 3 will put the box to be packaged into the box. Then the box flows forward and enters the sealing structure 4 to complete the sealing action. Finally, the box moves to the stacking structure 2, and the boxes are arranged and stacked under the restriction of the stacking structure 2.

[0038] A pair of side plates 41 are bolted to the roller line. A hinge shaft is fixedly installed on the side plates 41. A cutter holder 42 is rotatably installed on the hinge shaft. A cutter 43 and a lifting block 44 are bolted to the cutter holder 42.

[0039] The protective sleeve lifting block 453 is longer than the lifting block 44, so when the box passes through the sealing structure 4, it will first push the protective sleeve 452, the lifting block 44 and the cutter holder 42 to rotate around the hinge until the top of the box abuts against the lowest point of the lifting block 44. At this time, the box will slide, which will push the protective sleeve lifting block 453 and the protective sleeve 452 to slide along the slide rod 451 and squeeze the spring 454, so that the cutter 43 extends out of the protective groove. When the box passes the lifting block 44 but does not pass the protective sleeve lifting block 453, the cutter holder 42 loses its thrust and drives the cutter 43 to fall to cut the tape. When the box passes the protective sleeve lifting block 453, it will reset under the action of the spring 454 and the cutter 43 will be retracted into the protective groove.

[0040] The top of the slide bar 451 is provided with a threaded post 456, and the top block 455 is provided with a threaded groove that is threaded to engage with the threaded post 456. The bottom end of the top block 455 abuts against the top of the slide bar 451. The side wall of the top block 455 is provided with protective grooves. By unscrewing the top block 455, it is easy for the user to replace the spring 454.

[0041] Example 2:

[0042] like Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, a pair of hinge shafts are fixedly provided on the side plate 41, and a first connecting plate 46 and a second connecting plate 47 are rotatably mounted on the pair of hinge shafts respectively. A rotating shaft is fixedly provided on both the first connecting plate 46 and the second connecting plate 47, and a front pressure roller 5 and a rear pressure roller 6 are rotatably mounted on the corresponding rotating shafts respectively. The front pressure roller 5 and the rear pressure roller 6 can be lifted synchronously through the pressure roller transmission structure 7. A first elastic element 8 and an adjustable second elastic element 9 are respectively provided on the first connecting plate 46 and the second connecting plate 47.

[0043] Furthermore, the second elastic element 9 includes a second torsion spring 91, an adjusting knob 92, and a screw 93. The second connecting plate 47 is provided with a mounting groove 95 and a threaded hole that is threaded to the screw 93. One end of the screw 93 extends into the mounting groove 95, and the other end extends out of the second connecting plate 47 and is fixedly connected to the adjusting knob 92. The side plate 41 is provided with a second torsion spring hole 94. The second torsion spring 91 is sleeved on a hinge shaft that is rotatably engaged with the second connecting plate 47. One end of the second torsion spring 91 passes through the second torsion spring hole 94, and the other end abuts against the screw 93.

[0044] Furthermore, the first elastic element 8 includes a first torsion spring 81. Both the side plate 41 and the first connecting plate 46 are provided with first torsion spring holes 82. The first torsion spring 81 is sleeved on the hinge shaft that rotates with the first connecting plate 46, and the two ends of the first torsion spring 81 are respectively inserted into the corresponding first torsion spring holes 82.

[0045] Furthermore, the pressure roller transmission structure 7 includes a lever 71, a first connecting cylinder 72, a second connecting cylinder 73, and a cylindrical groove 74. The lever 71 is rotatably mounted on the side plate 41 via a hinge shaft. The first connecting cylinder 72 and the second connecting cylinder 73 are respectively fixed at both ends of the lever 71. The first connecting plate 46 and the second connecting plate 47 are provided with cylindrical grooves 74 that slide in cooperation with the first connecting cylinder 72 and the second connecting cylinder 73. The distance between the first connecting cylinder 72 and the corresponding hinge shaft of the lever 71 is greater than the distance between the second connecting cylinder 73 and the corresponding hinge shaft of the lever 71.

[0046] In this embodiment of the application, due to the aforementioned structure, a tape mounting device is fixedly installed on the side plate 41. During installation, the tape is first installed on the tape mounting device, and then the tape is pulled onto the front pressure roller 5. Later, during use, when the box to be sealed moves from under the front pressure roller 5, the box will push up the front pressure roller 5. The front pressure roller 5 drives the first connecting plate 46 to rotate around the corresponding hinge axis. Through the sliding engagement of the first connecting cylinder 72 and the corresponding cylindrical groove 74, the rotation of the first connecting plate 46 causes one end of the lever 71 with the first connecting cylinder 72 to lift, while the other end falls. Through the sliding engagement of the second connecting cylinder 73 and the corresponding cylindrical groove 74, when the end of the lever 71 with the second connecting cylinder 73 falls, it drives the second connecting plate 47 to rotate around the corresponding hinge axis, causing the rear pressure roller 6 to lift synchronously. Then the box moves at the bottom of the front pressure roller 5, and the front pressure roller 5 will simultaneously stick the tape to the box. When the box moves to the lifting block 44, the box will push the lifting block 44 and the cutter holder 42 to rotate around the corresponding hinge axis, causing the cutter 43 to lift. When the box passes the lifting block 44, the cutter holder 42 loses its thrust, causing the cutter 43 to fall, thereby completing the cutting of the tape.

[0047] A brush is fixedly installed on the side panel 41. When the box moves to the underside of the rear pressure roller 6, the rear pressure roller 6 presses the tape on the box. When the box moves to the underside of the brush, the brush makes the tape stick more firmly.

[0048] The distance between the hinge pins of the first connecting cylinder 72 and the lever 71 is greater than the distance between the hinge pins of the second connecting cylinder 73 and the lever 71. The lever 71 is a force-saving lever, which makes it easier for the box to simultaneously lift the front pressure wheel 5 and the rear pressure wheel 6 during the movement, and the box is less likely to get stuck.

[0049] Both the side plate 41 and the first connecting plate 46 are provided with first torsion spring holes 82. The first torsion spring 81 is sleeved on the hinge shaft that rotates with the first connecting plate 46. The two ends of the second torsion spring 91 are respectively inserted into the corresponding first torsion spring holes 82. The first torsion spring 81 can provide a certain pressure.

[0050] When it is necessary to increase the pressure, the adjusting knob 92 is turned, which drives the screw 93 to rotate. Since the second connecting plate 47 is provided with a threaded hole that is threaded to the screw 93, the rotation of the screw 93 can cause the screw 93 to slide in the direction of the second torsion spring 91, and apply pressure to the end of the second torsion spring 91 that is not inserted through the second torsion spring hole 94 to make it deform more, thereby increasing the pressure.
