Description

Technical Field

[0001] This invention relates to the field of wine box accessory assembly technology, and more specifically to a bending mechanism and a box opening trim assembly device. Background Technology

[0002] In the current packaging process for wine boxes, see Figure 1 First, the cover plate A and the surrounding strip B need to be assembled to form the cover plate-surround strip assembly C. In order to facilitate the assembly of the cover plate-surround strip assembly C with the mouth of the wine box, the surrounding strip B of the cover plate-surround strip assembly C needs to be bent and shaped, such as the automatic bending structure of the surrounding strip in the patent application document with patent number CN212603704U.

[0003] In the patent application document, the sash is first placed on a three-section platform in a horizontal position, and then the middle section of the conforming component (equivalent to a mold) is configured to press it on the middle section of the sash. The two side sections of the platform are driven to flip by two cylinders, so that the two side sections of the sash flip and attach to the two inclined sides of the conforming component to maintain a triangular state. Finally, the triangular sash is carried by the conforming component to the box opening and then the two side sections are opened and pasted to the inner wall of the box opening by the wedge block.

[0004] During the above actions, the two sides of the platform are independently controlled by two drive mechanisms, making it difficult to guarantee the synchronization of the flipping action of the two sides of the platform. This can easily lead to the displacement of the slats when bending, resulting in inaccurate bending. Furthermore, the flipping of the slats depends on the cooperation of two sets of structures, making the structure relatively complex. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a bending mechanism and a box opening lining assembly device that are simple in structure and can improve the bending accuracy of the lining strip.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a bending mechanism, comprising:

[0007] The retaining strip receiving platform includes a central section for adsorbing the middle section of the retaining strip and two ends for adsorbing the side sections of the retaining strip, respectively.

[0008] The driving mechanism includes a driving block that reciprocates in the vertical direction, two follower blocks that reciprocate synchronously in the horizontal direction with the movement of the driving block, and two rotating blocks that reciprocate synchronously with the movement of the two follower blocks.

[0009] The two rotating blocks can drive the two ends to swing with the two ends of the middle section as hinge points, and the ends can swing to be flush with the middle section or at an angle to the middle section.

[0010] Furthermore, a cover plate receiving platform is provided on one side of the enclosure strip receiving platform, and the cover plate receiving platform can tilt and support the cover plate.

[0011] Furthermore, one side of the retaining strip receiving platform is provided with a stop extending along its length, and the stop can abut against the opening end of the barrel when the retaining strip receiving platform is inserted into the barrel.

[0012] Furthermore, the driving mechanism also includes a guide rail that provides horizontal sliding guidance for the two follower blocks, and the two follower blocks are respectively provided with guide grooves that slide with the driving block, and the two guide grooves are arranged in a figure-eight shape.

[0013] Furthermore, the rotating block is a gear, and each of the following blocks is provided with a rack that meshes with the corresponding gear, and the two ends are respectively connected to the two gears.

[0014] Furthermore, the drive mechanism also includes a track having a trajectory that gradually decreases or increases in the vertical direction, and the follower block is provided with a follower wheel, and the follower wheel slides in cooperation with the track.

[0015] Furthermore, the drive mechanism also includes a lifting assembly and a connecting part disposed at the lifting end of the lifting assembly. The follower block is provided with a follower wheel, and the follower wheel is engaged with the connecting part.

[0016] A box opening trim assembly device, comprising:

[0017] The turntable is equipped with the bending mechanism that can receive the strip-cover plate assembly, and can sequentially move between the straightening station, the gluing station, the forming station and the assembly station;

[0018] The alignment station is used to regulate the posture of the upper strip-cover plate assembly of the bending mechanism;

[0019] The gluing station is used to apply glue to the bonding surface of the strip-cover plate assembly;

[0020] The forming station is used to fold the side section of the sash to an angle with the middle section of the sash.

[0021] The assembly station is used to fit the opening of the barrel / box onto the outside of the formed lining strip and to open the side section of the lining strip to adhere to the inner wall of the barrel / box.

[0022] The beneficial effects of this invention are reflected in:

[0023] 1. By setting up a linkage structure of driving block, follower block and rotating block, the follower block and rotating block move synchronously when the driving block moves, thereby realizing synchronous rotation of the two ends, that is, realizing synchronous bending of the side sections of the wrapping strip adsorbed at the two ends, thus ensuring the accuracy of the wrapping strip bending.

[0024] 2. The side section bending operation does not require mold forming, which simplifies the bending structure, reduces operation steps, and improves production efficiency. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The bending mechanism of the present invention

[0034] Example 1, see Figure 1 , 2 ,include:

[0035] The retaining strip receiving platform 1 includes a central part 101 for adsorbing the middle section B1 of the retaining strip and two end parts 102 for adsorbing the side sections B2 of the retaining strip respectively.

[0036] The driving mechanism 2 includes a driving block 201 that reciprocates in the vertical direction, two follower blocks 202 that reciprocate synchronously in the horizontal direction with the movement of the driving block 201, and two rotating blocks 203 that reciprocate synchronously with the movement of the two follower blocks 202.

[0037] The two rotating blocks 203 can drive the two ends 102 to swing about the two ends of the middle part 101 as hinge points, and the ends 102 can swing to be flush with or at an angle to the middle part 101. This design, through the linkage structure of the driving block 201, the follower block 202, and the rotating block 203, enables the follower block 202 and the rotating block 203 to move synchronously when the driving block 201 moves, thereby achieving synchronous rotation of the two ends 102. This allows the side sections B2 of the webbing, which are attached to the two ends 102, to bend synchronously, ensuring the accuracy of the bending of the webbing B. Furthermore, the bending operation of the side sections B2 does not require mold forming, simplifying the bending structure, reducing operation steps, and improving production efficiency.

[0038] In this embodiment, see Figure 3 , 5 The side of the retaining strip receiving platform 1 is also provided with a cover plate receiving platform 3, and the cover plate receiving platform 3 can tilt and support the cover plate A. This design makes the edge of the cover plate A and the retaining strip B form an angle. When the retaining strip B is assembled with the barrel box D, when the retaining strip B extends into the barrel box D, the opening end of the barrel box D can abut and limit the insertion position of the retaining strip B by the edge line of the angle formed by the cover plate A and the retaining strip B.

[0039] In this embodiment, see Figure 3 , 5 The retaining strip receiving platform 1 is further provided with a stop 4 extending along its length on one side, and the stop 4 can abut against the opening end of the barrel box D when the retaining strip receiving platform 1 is inserted into the barrel box D. This design allows for more precise positioning of the insertion position of the retaining strip B when it is inserted into the barrel box D during assembly, and preferably the stop 4 extends to both sides of the retaining strip receiving platform 1.

[0040] In this embodiment, see Figure 2The driving mechanism 2 further includes a guide rail 204 providing horizontal sliding guidance for the two follower blocks 202, and each of the two follower blocks 202 is provided with a guide groove 2021 that slides with the driving block 201, and the two guide grooves 2021 are arranged in a figure-eight shape. With this design, when the driving block 201 moves in the vertical direction, the follower blocks 202 can move in the horizontal direction in conjunction with the guide grooves 2021 and the guide rail 204.

[0041] In this embodiment, see Figure 3 The rotating block 203 is a gear, and each follower block 202 is provided with a rack 205 that meshes with the corresponding gear, and the two ends 102 are respectively connected to the two gears. With this design, when the follower block 202 moves, the rack 205 moves synchronously, thereby driving the corresponding gear to rotate, so as to realize the synchronous swing of the two ends 102.

[0042] In this embodiment, see Figure 3 , 4 The drive mechanism 2 further includes a track 206 having a trajectory that gradually decreases or increases in the vertical direction. The follower block 202 is provided with a follower wheel 207, and the follower wheel 207 is slidably engaged with the track 206. With this design, when the track 206 or the follower wheel 207 moves, the follower wheel 207 can be restricted by the track 206 to achieve reciprocating movement in the vertical direction.

[0043] Example 2, see Figure 3 , 5 .

[0044] It should be noted that in this embodiment, the only difference from Embodiment 1 is the driving structure of the driving block 201; all other structures are the same.

[0045] In this embodiment, the drive mechanism 2 further includes a lifting assembly 208 and a connecting portion 209 disposed at the lifting end of the lifting assembly 208. The follower block 202 is provided with a follower wheel 207, and the follower wheel 207 is engaged with the connecting portion 209. With this design, when the follower wheel 207 is located within the connecting portion 209, the lifting assembly 208 can achieve reciprocating movement of the drive block 201 in the vertical direction. The lifting assembly 208 can be a lifting cylinder, and the connecting portion 209 can be a block structure with a groove.

[0046] The present invention provides a box opening trim assembly device.

[0049] The straightening station 6 is used to straighten the posture of the upper strip-cover plate assembly C of the bending mechanism;

[0050] Glue application station 7 is used to apply glue to the bonding surface of the strip-cover plate assembly C;

[0051] Forming station 8 is used to fold the side section B2 of the sash B to an angle with the middle section B1 of the sash;

[0052] Assembly station 9 is used to fit the opening of the barrel box D onto the outside of the formed shroud B, and to open the side section B2 of the shroud to adhere to the inner wall of the barrel box D.

[0053] This design, in conjunction with turntable 5, integrates the bending of the sash B of the bending mechanism with the assembly of the barrel box D into a single device, improving the efficiency of wine box assembly. Furthermore, at the assembly station 9, after the sash side section B2 is opened to adhere to the inner wall of the barrel box D, the bending mechanism swings until the sash B is in the formed state before it can be removed from the barrel box D.
