Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a device for automatically inserting a wrapping strip into a packaging box and attaching it to the box wall. Background Technology

[0002] Paper packaging boxes, especially those used to hold valuable items such as mobile phones and watches, typically have internal reinforcing strips to enhance the structural strength and shape retention of the box, thereby improving its reliability. Traditional reinforcing strips are long strips of paper with three bendable creases. These strips must be manually bent into a square and then pasted onto the inner wall of the box, resulting in inefficiency, high labor intensity, and poor consistency.

[0003] To address the aforementioned issues, some automated equipment has emerged in the existing technology. However, these devices generally suffer from drawbacks such as complex structures, poor strip forming results, inaccurate box placement, or unreliable wall adhesion, making it difficult to meet the demands for efficient and stable production. Therefore, there is an urgent need for a fully automated device capable of automatically completing strip pushing, multi-segment bending and forming, precise box placement, and reliable wall adhesion. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a packaging machine's wrapping strip insertion and wall-attaching device, which solves the problems of low efficiency in manual wrapping strip application, complex structure of existing automated equipment, or unsatisfactory forming and wall-attaching effects. This device enables fully automated and efficient operation of the wrapping strip from material feeding, forming, box insertion to wall-attaching, thereby improving production efficiency and product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a packaging machine's box-feeding and wall-attaching device, comprising a frame, wherein a packaging box conveyor belt is provided on the frame, and the packaging box conveyor belt passes sequentially through a box-feeding mechanism and a box-attaching station; The packaging box conveyor belt includes a conveying platform, on which two push belts arranged in a circle and a clamping belt located between the two push belts are installed. The push belts and the clamping belt are respectively provided with evenly distributed protrusions and are driven by their respective first servo motors. The middle of the packaging box conveyor belt is provided with two adjustable limit baffles. The sheathing material feeding mechanism includes a platform fixed on the frame, on which a sheathing material trough, a first shaping trough, a second shaping trough, and a feeding robot are sequentially arranged; the first shaping trough and the second shaping trough are both rectangular in shape by sheathing plates and are internally connected; a pushing channel is provided at the bottom of the sheathing material trough, a pushing plate driven by a pushing cylinder is provided on one side of the pushing channel, a ramp backing plate is provided on the other side, and a pushing plate that enters and exits the pushing channel is also included, the pushing plate being driven by a pushing cylinder; It also includes a pusher plate extending from the bottom of the platform. The initial position of the pusher plate corresponds to the ramp backing plate and is installed on the slider of the first linear motion module to drag the sash from the ramp backing plate into the first shaping groove. A second linear motion module is provided between the first shaping groove and the second shaping groove. The slider of the second linear motion module is connected to a bracket. A first lifting cylinder is installed on the bracket. The piston rod of the first lifting cylinder is connected to a mounting base plate. A bending cylinder and a first clamping pneumatic finger are installed on the mounting base plate. The piston rod of the bending cylinder is connected to a downwardly vertical bending plate. The first clamping pneumatic finger is used to clamp the sash in the first shaping groove and transfer it to the second shaping groove. The box-entry robot is used to grab and transfer the lining strip in the second shaping groove to the packaging box on the packaging box conveyor belt; The wall-mounting station is located above the packaging box conveyor belt and includes a mounting frame. A third lifting cylinder is mounted on the mounting frame. The piston rod of the third lifting cylinder is connected to a lifting plate. A third clamping pneumatic finger is provided at one end of the lifting plate. A fourth linear motion module is also provided on the lifting plate. A mounting support plate is mounted on the slider of the fourth linear motion module. A horizontal cylinder is provided on the mounting support plate. The piston rod of the horizontal cylinder is connected to a guide plate. A bonding plate is mounted on the guide plate. The guide plate is connected to the slider of the fourth linear motion module through a guide rail slider guiding structure.

[0006] Furthermore, the first and second clamping pneumatic fingers have the same structure, both including a finger cylinder, with symmetrically arranged clamping plates connected to the two fingers of the finger cylinder.

[0007] Furthermore, the two limiting baffles are slidably mounted on the guide rail of the frame via their respective slides. The frame is also provided with a screw driven by a second servo motor. The two limiting baffles are respectively connected to the screw via threaded sleeves with opposite thread directions to synchronously adjust the spacing.

[0008] Furthermore, when the pusher plate on the pusher belt and the clamping plate on the clamping belt move with the belt, the pusher plate pushes the packaging box forward, and the clamping plate moves in the opposite direction under the drive of the corresponding first servo motor to clamp the packaging box for positioning.

High quality of the bedding strip forming: Through the pre-positioning of the inclined plate, the rapid transfer of the push plate, the initial bending of the first shaping groove, and the coordinated action of the second linear motion module with the lifting cylinder, bending cylinder and the first clamping pneumatic finger, the bedding strip is accurately and stepwise bent from the inclined state to the U-shape and then to the triangle, ensuring the accuracy and consistency of the bedding strip shape.

[0011] 3. Precise box positioning: The packaging box conveyor belt adopts a design with a push belt and a clamping belt combined with a convex plate, along with an adjustable limit baffle, which can effectively straighten and position the packaging box, ensuring that the wrapping strip is accurately placed in the predetermined position.

[0012] 4. Firm and reliable adhesion: The wall-attaching station uses a third-edge pneumatic finger to fix the strip to the box wall, and then the fourth linear motion module and horizontal cylinder drive the bonding plate to firmly and tightly press each fold of the strip onto the inner wall of the packaging box coated with glue, ensuring the firmness and flatness of the adhesion and improving the overall quality of the packaging box.

[0013] High adaptability: The spacing of the limit baffles is adjustable, which can adapt to packaging boxes of different sizes, enhancing the versatility and applicability of the equipment.

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 4 As shown, this embodiment provides a packaging machine's box-feeding and wall-attaching device, including a frame 100. A packaging box conveyor belt 200 is provided on the frame 100, and the packaging box conveyor belt 200 passes sequentially through the box-feeding mechanism 300 and the box-attaching station 500.

[0018] The packaging box conveyor belt 200 includes a conveying platform 210. Two push belts 220 and a clamping belt 230 are mounted on the conveying platform 210 in a circular arrangement, with the clamping belt 230 positioned between the two push belts 220.

[0019] The push belt 220 and the clamping belt 230 are respectively provided with evenly distributed push protrusions 221 and clamping protrusions 231. The push belt 220 and the clamping belt 230 are each driven by their corresponding first servo motors. During operation, the push belt 220 rotates in the forward direction, and the push protrusions 221 on it contact the bottom surface of the packaging box and push it forward.

[0020] At the same time, the clamping belt 230 is driven to rotate in the opposite direction by the corresponding first servo motor, and the clamping protrusion 231 on it abuts against the packaging box from another direction, forming a "pushing-clamping" synergistic effect, so that the packaging box maintains a regular posture and precise positioning during the conveying process.

[0021] Specifically, such as Figure 5 As shown, two adjustable-spaced limiting baffles 250 are provided in the middle of the packaging box conveyor belt 200 to ultimately limit the lateral position of the packaging box. The adjustment structure of the two limiting baffles 250 is as follows: a corresponding frame is provided. Guide rails are provided on both sides of the frame, and the two limiting baffles 250 are slidably mounted on the guide rails via their respective slides 290. The frame is also provided with a screw 270 driven by a second servo motor 260. The two limiting baffles 250 are threadedly connected to the screw 270 via threaded sleeves 280, and the helical directions of the threaded holes of the two threaded sleeves 280 are opposite.

[0022] When the second servo motor 260 drives the screw 270 to rotate, the two limit baffles 250 can move synchronously towards or away from each other, thereby adjusting the spacing to accommodate packaging boxes of different widths.

[0023] The sash feeding mechanism 300 is fixed on the frame 100 and includes a platform 310. The platform 310 is sequentially provided with a sash material trough 320, a first shaping trough 370, a second shaping trough 380, and a feeding robot 400. Both the first shaping trough 370 and the second shaping trough 380 are rectangular in shape formed by sash panels and are internally interconnected, used for gradually bending and shaping the sash.

[0024] The bottom of the sheathing material trough 320 is provided with a pushing channel 330. A pushing plate 331 is provided on one side of the pushing channel 330, and a ramp backing plate 340 is provided on the other side. The pushing plate 331 is driven by a pushing cylinder 332, which can push out the sheathings stacked at the bottom of the sheathing material trough 320 one by one, so that they lean against the ramp surface of the ramp backing plate 340, making the sheathings tend to stand upright.

[0025] It also includes a pusher plate 350 extending from the bottom of the platform 310. The initial position of the pusher plate 350 is set directly below or to the side of the ramp backing plate 340 to receive the retaining strip. The pusher plate 350 is mounted on the slider of the first linear motion module 360. When the first linear motion module 360 ​​is activated, it drives the pusher plate 350 to quickly drag the retaining strip abutting against the ramp backing plate 340 to the entrance of the first shaping groove 370. Under the guidance of its own shape and the groove, the retaining strip bends along a preset crease into a U-shape with one side longer.

[0026] Specifically, such as Figure 7As shown, a second linear motion module 390 is disposed between the first shaping groove 370 and the second shaping groove 380. The slider of the second linear motion module 390 is connected to a bracket 391. A first lifting cylinder 392 is mounted on the bracket 391, with its piston rod pointing downwards and connected to a mounting base plate 393. A bending cylinder 394 is mounted on one side of the mounting base plate 393, with its piston rod connected to a downwardly vertically positioned bending plate 395. A first clamping pneumatic finger 396 is mounted on the other side of the mounting base plate 393.

[0027] The workflow is as follows: Driven by the second linear motion module 390 and the first lifting cylinder 392, the first clamping pneumatic finger 396 descends into the first shaping groove 370 and clamps the U-shaped sash. Then, the first clamping pneumatic finger 396 moves upwards and laterally above the second shaping groove 380, releasing it. When the sash falls into the second shaping groove 380, one of its long sides first enters the groove opening and bends inwards along the corresponding crease. Next, the bending cylinder 394 pushes the bending plate 395 downwards, bending the other short side of the sash inwards as well. Thus, the sash is bent into a triangular shape within the second shaping groove 380. The box-loading robot 400 picks up the triangular sash from the second shaping groove 380 and transfers it to the pre-positioned packaging box on the packaging box conveyor belt 200.

[0028] Specifically, such as Figure 6 As shown, the box-loading robot 400 includes a third linear motion module 410, and a mounting plate 420 is connected to the slider of the third linear motion module 410. A second lifting cylinder 430 is mounted on the mounting plate 420, and the piston rod of the second lifting cylinder 430 is connected to a frame plate 440. One or more second clamping pneumatic fingers 450 are mounted on the frame plate 440.

[0029] The structure of the second clamping pneumatic finger 450 is the same as that of the first clamping pneumatic finger 396. Both include a finger cylinder, and symmetrically arranged clamping plates are connected to the two fingers of the finger cylinder. The clamping plates are opened and closed by driving the finger cylinder to achieve clamping and release.

[0030] The second lifting cylinder 430 drives the frame plate 440 to descend, the second clamping pneumatic finger 450 clamps the strip in the second shaping groove 380, and then the third linear motion module 410 and the lifting cylinder work together to accurately move the strip to the predetermined position in the packaging box and release it.

[0031] Specifically, such as Figure 8As shown, the wall-attaching station 500 is located above the packaging box conveyor belt 200, and its structure includes a mounting frame 510. A third lifting cylinder 520 is mounted on the mounting frame 510, and the piston rod of the third lifting cylinder 520 is connected to a lifting plate 530. A third clamping pneumatic finger 531 is provided at one end of the lifting plate 530 for clamping one side wall of the packaging box and one folded edge of the wall-attaching strip, thus providing a fixing function. A fourth linear motion module 540 (such as an XY bidirectional module) is also provided on the lifting plate 530. A mounting support plate 550 is mounted on the slider of the fourth linear motion module 540.

[0032] A horizontally positioned cylinder 560 is mounted on the mounting plate 550, and the piston rod of the horizontally positioned cylinder 560 is connected to a guide plate 561. A fitting plate 562 is mounted on the guide plate 561. The guide plate 561 is connected to the slider of the fourth linear motion module 540 through a guide rail slider guiding structure 570 to ensure the smoothness of the movement.

[0033] During operation, the third lifting cylinder 520 drives the lifting plate 530 to descend, and the third clamping pneumatic finger 531 (which has the same structure as the first and second clamping pneumatic fingers) completes the clamping. Subsequently, the fourth linear motion module 540 and the horizontal cylinder 560 work together to drive the bonding plate 562 to move back and forth and left and right in the horizontal plane. The bonding plate 562 moves down to the inner hole of the triangular strip inside the packaging box, and then, according to a preset path, it sequentially taps or scrapes each fold of the strip along the inner wall of the packaging box, making it tightly adhere to the inner wall that has been pre-sprayed with glue, thus completing the automatic wall-attaching process of the strip.

[0034] 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.
