DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-8As shown, a cotton swab packaging device comprises a circular rail 19, the circular rail 19 is arranged at the center of the frame, and a plurality of bag clamping mechanisms are arranged on the circular rail 19, the bag clamping mechanisms are opened and closed and changed in pitch by adjusting the frame 23, and packaging lines with the same structure and 180-degree rotation are arranged on both sides of the circular rail 19, and the packaging lines are arranged in sequence from the beginning to the end: a bag making mechanism, which presses two groups of material belts conveyed close to each other into at least one bag body with an opening; a bag separating mechanism, which passes the pressed bags through a The bag is conveyed through and cut; the tear-off seam rolling mechanism is clamped by the clamping claw 14 for cutting, and the tear-off seam is rolled out between the cut bags; the bag opening mechanism opens the bag sent to the bag clamping mechanism by the clamping claw 14; the material taking mechanism clamps the cotton swab through the clamping claw of the corresponding sieve plate 1 and puts it into the bag after the bag is opened; the sealing mechanism seals the bag with the cotton swab inserted. The basic process is as follows: the material for making the front and back of the bag is placed on the bag material rack 2, and passes through the bag making machine vertically in a close fit. After passing through the bag making mechanism, the strip is pressed into a bag body with an opening. At this time, the bags are not disconnected from each other. After passing through the bag dividing mechanism, it is cut. The cutting here can be single cutting or multiple bags can be cut as a group (for example, 3 bags are cut as a group or 2 bags are cut as a group). After the multiple bags are cut, they are moved to the easy-tear seam rolling mechanism through the clamping claw 14 to roll the easy-tear seams between the bags to facilitate separation in the later use. After rolling, the bags are moved When the bag clamping mechanism moves to the bag opening mechanism through the circular rail 19, the bag clamping mechanism will change its distance, so as to facilitate the bag opening and prevent the two sides of the bag body from shrinking and falling off from the bag clamping mechanism when the bag is opened. After the bag is opened, the circular rail continues to move to the material picking mechanism, and the material picking claw grabs the cotton swab and puts it into the bag body. The clamping mechanism moves to the sealing mechanism again, and the bag mouth is sealed by the sealing mechanism.

[0028] The bag clamping mechanism includes a control shaft 26 and a pitch-changing module 27. The bag pressing arm 1 24 is arranged on the control shaft 26, and the bag pressing arm 25 is arranged on the pitch-changing module 27, and the bottom of the bag pressing arm 25 is hinged to the bottom of the bag pressing arm 1 24. The end of the control shaft 26 is provided with a bevel gear meshing group, which is driven by a cam follower at a corresponding position. The end of the pitch-changing module 27 is provided with a bevel gear meshing group, which is driven by a cam follower at a corresponding position. The two groups of cam followers respectively cooperate with the upper and lower cam grooves of the adjusting frame 23. The shaft body of the control shaft 26 is provided with a groove body for pitch-changing transverse movement and will not fall off. The bag clamping mechanism is fixed on the annular rail 19. When it is not in the bag clamping station and the material taking station, the cam follower will not contact the cam groove in the adjusting frame 23. Only when it reaches a specific position, the cam follower will contact the groove wall of the cam groove, thereby changing the pitch and opening and closing.

[0029] The bag making mechanism comprises two groups of movable base plates 7, on which bag making pressing moulds are fixed, wherein the bottom of one group of movable base plates 7 is hinged to the bottom plate, and the top is hinged to one end of the connecting arm 6; the bottom of the other group of movable base plates is hinged to the bottom plate, the top is hinged to one end of the linkage block 1 4, the other end of the linkage block 1 4 is hinged to one end of the linkage block 2 5, the other end of the linkage block 2 5 is hinged to the other end of the connecting arm 6, the hinged joints of the linkage block 2 5 and the connecting arm 6 and the hinged joints of the linkage block 1 4 and the linkage block 2 5 are limited by side guide plates 8, and a lifting cylinder is arranged at the hinged joints of the linkage block 1 4 and the linkage block 2 5, where the bag making mechanism is pressed in a linkage manner, and the power source is the lifting cylinder, when the lifting cylinder is lifted, the linkage block 1 and the linkage block 2 are respectively expanded to both sides, the linkage block 1 4 directly pushes one of the pressing moulds outward, and the linkage block 2 5 retracts the other pressing mould through the connecting arm 6, thereby closing the two groups of pressing moulds.

[0030] A material feeding rack 3 is arranged at the entrance of the two groups of movable base plates 7. The material feeding rack 3 includes two rods, a gap is arranged between the rods for the material to pass through, and limit blocks are arranged at the upper and lower ends of the rods to ensure that the overlapping heights of the two groups of material are consistent for easy pressing.

[0031] The bag dividing mechanism includes a feeding wheel 11 and a cutting block 13. The feeding wheel 11 is provided in at least four groups and is respectively connected to the upper and lower ends of the two shafts so that the upper and lower feeding wheels 11 of the two shafts are close to each other. A telescopic cylinder is provided on the side of one of the shafts, and the telescopic cylinder is used to displace it so that it is close to or away from the other shaft. A cutting block 13 is provided at the rear of the feeding wheel 11 to cut the bag body transmitted by the feeding wheel 11.

[0032] A stopper 10 for the bag to pass through is arranged in front of the feeding wheel 11, and a tearing knife 9 controlled by a telescopic cylinder is arranged on the inner wall of the stopper 10. A guide frame 12 is arranged at the entrance of the cutting block 13 for the bag to pass through and position. The stopper 10 and the tearing knife 9 here are not limited to one group, and multiple groups can also be arranged. When multiple bags are combined into one group, multiple tearing knives 9 can be used to make easy-to-tear openings between the bag bodies.

[0033] The tear-away seam rolling mechanism includes a rolling wheel 15, which is arranged on a movable block 16 and moves up and down through the cooperation of the movable block 16 and the screw rod. A rolling plate is fixed on the corresponding surface of the rolling wheel 15. Because multiple connected bags need to be separated during use, tear-away seams are rolled out at the connection points in advance, which makes it easier to separate individual bags.

[0034] The bag opening mechanism comprises an adsorption head 17 , which is arranged in two rows and opposite to each other and respectively arranged on two fixed seats, and the two fixed seats are connected to a screw rod 18 with a bidirectional thread.

[0035] The sealing mechanism includes a control block 28, which is connected to the shaft body. The upper and lower holes of the control block 28 respectively control the sealing block 1 29 and the sealing block 2 30 through connecting rods. The rotation of the control block 28 is achieved by connecting the top with the lifting cylinder.

[0036] In addition, a positioning mechanism may be provided on the side of the annular rail 19 for secondary positioning to facilitate the bagging rack 22 to be positioned in place.

[0037] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity from another entity, but do not necessarily require or imply the existence of any such actual relationship or order between these entities.
