Description

Technical Field

[0001] This utility model relates to a packaging flipping mechanism for folded filter cores, belonging to the technical field of packaging equipment for folded filter cores. Background Technology

[0002] In the field of protective face mask manufacturing technology, pleated filter cartridges have the characteristic of filtering dust and toxic substances from the air. After production, the pleated filter cartridges need to be packaged using a packaging device with a transparent film. Currently, the upper surface of the pleated filter cartridges after production is printed with information such as the manufacturer's production date. To ensure perfect packaging, a flipping mechanism is needed to flip the filter cartridge so that the production information corresponds to the plane of the film packaging, facilitating the display of the production information. Otherwise, the production information will correspond to the overlap line of the film packaging, resulting in the film overlap line obscuring the production information.

[0003] Existing flipping mechanisms, such as the mask flipping device for mask production disclosed in utility model patent CN221739338U, can meet the requirements for use to a certain extent, but they have the following problems:

[0004] First: The existing flipping mechanism has a flat flipping plate structure; when flipping, the filter or mask is not restrained and is easily thrown out, causing the flipping to fail.

[0005] Second: The existing flipping mechanism uses a single drive belt to transport the filter core or mask. When the single drive belt pushes the filter core or mask, it has strict requirements on the position of the mask on the single drive belt. When the filter core or mask deviates slightly from the track, it is difficult for the single drive belt to transport the filter core or mask to the flipping plate in the correct posture. Therefore, the existing flipping mechanism needs to be combined with a straightening mechanism to straighten the filter core or mask, which has a complex structure. Summary of the Invention

[0006] The purpose of this utility model is to provide a compact and ingeniously designed packaging flipping mechanism for folded filter cores that solves the problems of high failure rate and complex structure of existing flipping mechanisms.

[0007] The technical solution of this utility model is:

[0008] A packaging flipping mechanism for a folded filter core includes a mounting frame, a flipping fork, a main conveyor belt, a front conveyor belt, a rear conveyor belt, a drive mechanism, and a flipping motor; characterized in that: two sets of main conveyor belts are symmetrically mounted on the mounting frame via the drive mechanism; the front conveyor belt and the rear conveyor belt are spaced apart between the main conveyor belts via the drive mechanism; and the flipping fork is mounted on the mounting frame between the front conveyor belt and the rear conveyor belt via the flipping motor and a rotating shaft.

[0009] The flip fork has an integrated structure, which includes a middle cylinder and a limiting plate; the middle cylinder is fixedly mounted on the rotating shaft; two sets of limiting plates are symmetrically mounted on the upper and lower ends of the middle cylinder; and a storage groove is formed between the two sides of the middle cylinder and the limiting plates.

[0010] The drive mechanism includes a drive motor, a drive shaft, a driven shaft, intermediate shaft A, and intermediate shaft B; one end of the mounting bracket is equipped with the drive shaft via the drive motor; the other end of the mounting bracket is equipped with the driven shaft; intermediate shaft A and intermediate shaft B are installed at intervals on the mounting bracket between the drive shaft and the driven shaft; two sets of main transmission belts are symmetrically mounted on the drive shaft and the driven shaft; a front transmission belt is installed between the drive shaft and intermediate shaft A; and a rear transmission belt is installed between intermediate shaft B and the driven shaft.

[0011] A driven roller is mounted on the mounting bracket above the rear conveyor belt via a torsion spring and a swing arm; the driven roller always tends to move closer to the rear conveyor belt under the action of the torsion spring force.

[0012] A protective cover is installed on the mounting bracket above the flip fork.

[0013] The advantages of this utility model are:

[0014] The packaging flipping mechanism of this folded filter core is compact and ingeniously designed. It can flip the folded filter core through the storage trough and can complete the conveying of the folded filter core through the cooperation of the main conveyor belt, the front conveyor belt and the rear conveyor belt.

Detailed Implementation

[0024] The packaging flipping mechanism of this folded filter core includes a mounting bracket 1, a flipping fork 7, a main conveyor belt 2, a front conveyor belt 3, a rear conveyor belt 4, a drive mechanism, and a flipping motor 5 (see the instruction manual appendix). Figure 1 , 2 3 and 4).

[0025] Two sets of main conveyor belts 2 are symmetrically mounted on the mounting frame 1 via a drive mechanism; a front conveyor belt 3 and a rear conveyor belt 4 are installed between the main conveyor belts 2 at intervals via the drive mechanism.

[0026] The drive mechanism includes a drive motor 11, a drive shaft 12, a driven shaft 13, an intermediate shaft A14, and an intermediate shaft B15.

[0027] One end of the mounting bracket 1 is equipped with a drive shaft 12 via a drive motor 11; the other end of the mounting bracket 1 is equipped with a driven shaft 13; intermediate shafts A14 and B15 are installed at intervals on the mounting bracket 1 between the drive shaft 12 and the driven shaft 13; two sets of main conveyor belts 2 are symmetrically mounted on the drive shaft 12 and the driven shaft 13; a front conveyor belt 3 is installed between the drive shaft 12 and the intermediate shaft A14; and a rear conveyor belt 4 is installed between the intermediate shaft B15 and the driven shaft 13.

[0028] The purpose of this drive mechanism configuration is to enable the drive motor 11 to drive the drive shaft 12 to rotate, while the drive shaft 12 can drive the two main conveyor belts 2 to rotate synchronously with the cooperation of the driven shaft 13; while the driven shaft 13 can drive the rear conveyor belt 4 to rotate synchronously with the cooperation of the intermediate shaft B15; and at the same time, while the drive shaft 12 can drive the front conveyor belt 3 to rotate with the cooperation of the intermediate shaft A14.

[0029] When operating in this way, the two sets of main conveyor belts 2, front conveyor belt 3 and rear conveyor belt 4 can rotate synchronously, thereby avoiding the problem of misalignment caused by the different rotation speeds of the main conveyor belts 2, front conveyor belt 3 and rear conveyor belt 4 when transporting the folded filter core.

[0030] The overall width of the two main conveyor belts 2 should be greater than the width of the folded filter core, so as to avoid the problem that the main conveyor belts 2 cannot transport the folded filter core.

[0031] The purpose of installing a front conveyor belt 3 and a rear conveyor belt 4 between the two sets of main conveyor belts 2 is twofold: first, the two sets of main conveyor belts 2 can transport the folded filter core under the joint transport of the front conveyor belt 3 and the rear conveyor belt 4, ensuring the stable transport of the folded filter core; second, when the folded filter core is out of contact with the front conveyor belt 3 and the rear conveyor belt 4, the two sets of main conveyor belts 2 can input or output the folded filter core to the flip fork 7, thereby avoiding the problem that the folded filter core cannot be stably input or output to the flip fork 7.

[0032] A tilting fork 7 is mounted on the mounting bracket 1 between the front conveyor belt 3 and the rear conveyor belt 4 via a tilting motor 5 and a rotating shaft 6. A protective cover 18 is mounted on the mounting bracket 1 above the tilting fork 7. The purpose of the protective cover 18 is to isolate the tilting fork 7 from the outside world, thereby preventing external debris from entering the tilting fork 7 and affecting the operation of the packaging tilting mechanism.

[0033] The flip fork 7 has an integrated structure, including a middle cylinder 8 and a limiting plate 9; the middle cylinder 8 is fixedly mounted on the rotating shaft 6; two sets of limiting plates 9 are symmetrically mounted on the upper and lower ends of the middle cylinder 8; a storage slot 10 is formed between the two sides of the middle cylinder 8 and the limiting plates 9 (see the attached instruction manual). Figure 7 ).

[0034] The purpose of setting up the flip fork 7 in this way is to ensure that during operation, after the main conveyor belt 2 and the front conveyor belt 3 transport the folded filter core to the storage slot 10 in the flip fork 7, the flip fork 7 rotates 180° and transports the folded filter core to contact the main conveyor belt 2 and the rear conveyor belt 4; the main conveyor belt 2 and the rear conveyor belt 4 then output the folded filter core, thus completing the flipping operation of the folded filter core.

[0035] A photoelectric sensor (not shown in the attached diagram of the manual) is installed on the mounting bracket 1 on one side of the flip fork 7; after the photoelectric sensor detects the folded filter core, it can control the flip motor 5 to drive the flip fork 7 to move.

[0036] A driven roller 17 is mounted on the mounting bracket 1 above the rear conveyor belt 4 via a torsion spring and a swing arm 16; the driven roller 17 always tends to move closer to the rear conveyor belt 4 under the action of the torsion spring. When working in this way, the driven roller 17 will press the folded filter element with a certain elastic pressure, so that it will be output in a uniform posture under the conveying action of the rear conveyor belt 4.

[0037] The packaging and flipping mechanism of this folded filter core works as follows: during operation, the processing device drops the finished folded filter core onto the main conveyor belt 2 and the front conveyor belt 3; subsequently, the rotating main conveyor belt 2 and the front conveyor belt 3 transport the folded filter core to the storage slot 10 in the flipping fork 7, after which the flipping fork 7 rotates 180°, transporting the folded filter core to contact with the main conveyor belt 2 and the rear conveyor belt 4; the main conveyor belt 2 and the rear conveyor belt 4 then output the folded filter core, thus completing the flipping operation of the folded filter core.

[0038] The packaging flipping mechanism of this folded filter core is compact and ingeniously designed. It can flip the folded filter core through the storage trough 10 and can complete the conveying of the folded filter core through the cooperation of the main conveyor belt 2, the front conveyor belt 3 and the rear conveyor belt 4. This solves the problems of high failure rate and complex structure of existing flipping mechanisms and is particularly suitable for the packaging of folded filter cores.
