Description

Technical Field

[0001] This utility model relates to the field of packaging box assembly machine technology, and in particular to a paper box EVA square frame feeding machine. Background Technology

[0002] Packaging boxes, such as cigarette boxes and wine boxes, generally consist of a box body and an EVA liner inside the box. The EVA liner is a square frame formed by four side frames connected end to end. Traditional packaging box assembly machines typically involve manually opening the EVA to form a square frame, and then using assembly equipment to insert the EVA frame into the box. This semi-automated assembly process is slow, has high labor costs, and is prone to human error, resulting in a product yield that does not meet the requirements for mass production. Therefore, it is necessary to improve this process. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paper box EVA square frame feeding machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a paper box EVA square frame feeding machine, which includes a frame, a positioning mechanism and an EVA feeding mechanism disposed on the frame, and a material transfer mechanism for picking up EVA in the EVA feeding mechanism and transferring it to the positioning mechanism. The material transfer mechanism is equipped with a slidably disposed rotating frame clamp. The rotating frame clamp is provided with a fixed seat, a rotating cylinder mounted on the fixed seat, a fixed arm fixedly mounted on the rotating cylinder, a swing arm driven and connected to the rotating cylinder, and four picking arms for picking up EVA. The first picking arm and the second picking arm are respectively hinged to the two ends of the swing arm, and the third picking arm and the fourth picking arm are respectively hinged to the two ends of the fixed arm. The four picking arms are sequentially hinged end to end by hinge members.

[0005] In a further technical solution, during material feeding, the first and second picking arms are arranged longitudinally, while the third and fourth picking arms are arranged horizontally, forming a square frame structure with the four picking arms.

[0006] During material handling, the first and second material handling arms come together under the action of the rotating swing arm. The fourth material handling arm rotates 90° under the pushing and pulling action of the first material handling arm and is set parallel to the first material handling arm. The third material handling arm rotates 90° under the pushing and pulling action of the second material handling arm and is set parallel to the second material handling arm.

[0007] In a further technical solution, the hinge component includes a hinge shaft and two hinge blocks respectively sleeved on the hinge shaft, with one hinge block correspondingly connected to a material handling arm.

[0008] In a further technical solution, the material transfer mechanism further includes a material transfer frame slidably connected to the frame, a lifting and picking drive assembled on the material transfer frame, a transverse feeding drive for driving the material transfer frame to move laterally, and a lifting plate driven and connected to the lifting and picking drive, wherein the fixed base is fixedly installed on the fixed base.

[0009] In a further technical solution, the positioning mechanism includes four outer frame positioning devices, with one outer frame positioning device corresponding to one material handling arm. Each outer frame positioning device includes a cylinder assembly seat on the frame, an outer frame positioning cylinder mounted on the cylinder assembly seat, and an outer frame positioning baffle connected to the outer frame positioning cylinder.

[0010] In a further technical solution, the positioning mechanism also includes four inner frame positioning baffles, one of which is used in conjunction with the outer frame positioning baffle.

[0011] In a further technical solution, the positioning mechanism also includes a finger gripper cylinder and four movable sliders driven by the finger gripper cylinder, with an inner frame positioning baffle fixedly installed on one of the movable sliders.

[0012] In a further technical solution, the frame is provided with an adjustable groove, and the cylinder mounting seat is installed in the adjustable groove.

[0013] In a further technical solution, the transverse feeding drive includes a transverse motor, a belt drive mechanism connected to the transverse motor, and a belt slider connected to the belt drive mechanism, wherein the transfer frame is connected to the belt slider.

[0014] The advantages of this invention compared to the prior art after adopting the above structure are:

[0015] This invention supplies EVA through an EVA feeding mechanism. At this time, the EVA is in the shape of a strip. The rotating frame clamp picks up the strip-shaped EVA. When the material transfer mechanism moves the EVA to the positioning mechanism, the rotating frame clamp makes the EVA open into a square shape. Finally, the positioning mechanism positions the EVA. The rotating frame clamp completes the picking and frame opening processes at the same time. This structural design is ingenious and has high work efficiency. Attached Figure Description

[0023] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, the present invention provides a paper box EVA square frame feeding machine, which includes a frame 1, a positioning mechanism 2 and an EVA feeding mechanism 3 disposed on the frame 1, and a material transfer mechanism 4 for picking up EVA in the EVA feeding mechanism 3 and transferring it to the positioning mechanism 2. The material transfer mechanism 4 is equipped with a slidably disposed rotating frame clamp. The rotating frame clamp is provided with a fixed base 40, a rotating cylinder 41 installed on the fixed base 40, a fixed arm 42 fixedly installed on the rotating cylinder 41, a swing arm 43 driven and connected to the rotating cylinder 41, and four picking arms 44 for picking up EVA. The first picking arm 44 and the second picking arm 44 are respectively hinged to the two ends of the swing arm 43, and the third picking arm 44 and the fourth picking arm 44 are respectively hinged to the two ends of the fixed arm 42. The four picking arms 44 are sequentially hinged end to end by hinge members 45.

[0025] During operation, the EVA feeding mechanism 3 supplies EVA. At this time, the EVA is in the shape of a strip. The rotating frame clamp picks up the strip-shaped EVA. When the transfer mechanism 4 transfers the EVA to the positioning mechanism, the rotating frame clamp makes the EVA open into a square shape. Finally, the positioning mechanism 2 positions the EVA.

[0026] During material handling, the first and second material handling arms 44 are brought together by the rotating swing arm 43. The fourth material handling arm 44 rotates 90° under the pushing and pulling action of the first material handling arm 44 and is set parallel to the first material handling arm 44. The third material handling arm 44 rotates 90° under the pushing and pulling action of the second material handling arm 44 and is set parallel to the second material handling arm 44.

[0027] During material feeding, the first and second picking arms 44 are arranged longitudinally, while the third and fourth picking arms 44 are arranged horizontally. The four picking arms 44 form a square frame structure, which causes the EVA to open from a strip shape into a square frame.

[0028] This invention uses a rotating frame clamp to simultaneously complete the picking and frame-setting processes, resulting in a clever structural design and high work efficiency.

[0029] In a further technical solution, the hinge 45 includes a hinge shaft 450 and two hinge blocks 451 respectively sleeved on the hinge shaft 450, with one hinge block 451 correspondingly connected to a material handling arm 44.

[0030] In this embodiment, the material transfer mechanism 4 further includes a material transfer frame 46 slidably connected to the frame 1, a lifting and picking drive 47 assembled on the material transfer frame 46, a transverse feeding drive 48 for driving the material transfer frame 46 to move laterally, and a lifting plate 49 driving the lifting and picking drive 47. The fixed base 40 is fixedly installed on the fixed base 40.

[0031] The transverse feeding drive 48 includes a transverse motor 480, a belt drive mechanism 481 connected to the transverse motor 480, and a belt slider 482 connected to the belt drive mechanism 481. The material transfer frame 46 is connected to the belt slider 482. During feeding, the belt drive mechanism 481 drives the belt slider 482 to slide. The sliding belt slider 482 causes the rotating frame clamp to move to a designated position. The lifting and picking drive 47 drives the lifting plate 49 to move up and down, so that the rotating frame clamp can pick up and put down materials.

[0032] In this embodiment, the positioning mechanism 2 includes four outer frame positioning devices 20. Each outer frame positioning device 20 is correspondingly arranged with a material picking arm 44. Each outer frame positioning device 20 includes a cylinder mounting base 200 provided on the frame 1, an outer frame positioning cylinder 201 installed on the cylinder mounting base 200, and an outer frame positioning baffle 202 that drives the outer frame positioning cylinder 201 to move. The outer frame positioning cylinder 201 drives the outer frame positioning baffle 202 to move, and the outer frame positioning baffle 202 abuts against the outer edge of the EVA frame.

[0033] More specifically, the positioning mechanism 2 also includes four inner frame positioning baffles 21. During positioning, one inner frame positioning baffle 21 is used in conjunction with the outer frame positioning baffle 202. The outer frame positioning baffle 202 and the inner frame positioning baffle 21 move closer to each other and abut against the EVA square frame.

[0034] In this embodiment, the positioning mechanism 2 further includes a finger gripper cylinder 22 and four movable sliders 23 driven and connected to the finger gripper cylinder 22, and an inner frame positioning baffle 21 is fixedly installed on a movable slider 23.

[0035] In this embodiment, the frame 1 is provided with an adjustable waist groove 10, and the cylinder mounting seat 200 is installed in the adjustable waist groove 10. This structural design can adjust the position of the outer frame positioning device 20, thereby adapting to EVA square frames of different sizes.

[0036] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
