Technical Field

[0001] The invention relates to the technical field of gauze block production, and in particular to a gauze block folding, bagging and packaging integrated machine. Background Art

[0002] Gauze sheets are commonly used clean bandaging materials in medical work. Gauze sheets generally need to be folded into multiple layers before packaging. Currently, there are two main forms of gauze sheet folding: manual folding and mechanical folding. Manual folding is slow, inefficient, labor-intensive, and labor-intensive, and the folding quality is unstable. Mechanical folding uses a dedicated gauze folding device for folding, but the current gauze folding device has a complex structure and a large volume, and occupies a large area and production space when in use.

[0003] Moreover, the current gauze blocks are usually folded in a single layer, and the required packaging bags are relatively large. If double-folded, additional processing steps are required, and the process is discontinuous, resulting in low production efficiency. At the same time, the current gauze blocks are cut, folded, bagged, and packaged by different equipment, with a low degree of automation, making production extremely inconvenient.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] like Figure 1 As shown, the present invention provides a gauze block folding, bagging and packaging integrated machine, comprising:

[0045] The cutting device 20 includes a frame 21, and a first feeding roller 10 is provided on one side of the frame 21. The cutting device 20 transmits the gauze roll 11 to a certain distance through the first feeding roller 10 and cuts it;

[0046] The cutting device 20 further includes a first driving cylinder 22 mounted on the upper side of the frame 21, a mounting seat 23 is fixed to the end of the piston rod of the first driving cylinder 22, and a cutting knife 24 for cutting the gauze is fixed to the lower side of the mounting seat 23;

[0047] When the first driving cylinder 22 drives the mounting base 23 to perform a vertical linear motion, the cutting knife 24 can contact the gauze and cut it.

[0048] In this embodiment, the first driving cylinder 22 drives the mounting seat 23 and the cutting knife 24 to move downward, thereby cutting off the gauze strip extending from the gauze roll 11. The first feeding roller 10 can be controlled by an external controller to transmit the gauze strip to a specified length, thereby achieving equal-length cutting and ensuring the stability of the gauze block product.

[0049] Combination Figure 4 and Figure 5 As shown, the folding device 30 is arranged at the lower side of the cutting device 20, and supports the cutting device 20 while performing double-layer folding on the cut gauze strips;

[0050] Specifically, the folding device 30 includes a pleating seat 32 and a pleating mechanism 31 installed on the lower side of the mounting seat 23 for generating a first layer of pleats on the gauze strip;

[0051] The surface of the pleating seat 32 has a pleating groove 35 corresponding to the pleating mechanism 31, and the interior of the pleating seat 32 has a folding component for secondary folding the gauze strip that has completed the first layer of pleats in the pleating groove 35;

[0052] The folding assembly includes a pressing groove 37 located on one side of the pleating groove 35 and a moving groove 36 located on the other side of the pleating groove 35;

[0053] It also includes a second driving cylinder 33 fixed on one side of the crimping seat 32, and the end of the piston rod of the second driving cylinder 33 is fixed with a crimping plate 34 located inside the movable groove 36. When the second driving cylinder 33 drives the crimping plate 34 and the gauze strip to move into the pressing groove 37, they are squeezed with the inner wall of the pressing groove 37 to complete the secondary folding.

[0054] The bottom of the pressing groove 37 has a material dropping groove 38 corresponding to a single conveying position of the conveying device 40 .

[0055] Combination Figure 8 As shown, the cut gauze strip enters the pleating groove 35 under the driving action of the first driving cylinder 22, the mounting seat 23 and the pleating mechanism 31. The V-shaped setting of the pleating groove 35 can make the middle part of the cut gauze strip have the first pleat;

[0056] The second driving cylinder 33 then drives the pleating plate 34 to move, so that the gauze strip located in the pleating groove 35 enters the pressing groove 37 and moves along the pressing groove 37 to form a second pleat, thereby completing the double-layer folding and reducing its occupied space.

[0057] In order to ensure that the pleating mechanism 31 remains in a compacted state during the second pleating process, the following technical solution is proposed in this embodiment:

[0058] like Figure 6As shown, the crimping mechanism 31 includes a connecting seat 313 connected to the mounting seat 23, a connecting frame 314 that can move linearly along the height direction of the connecting seat 313 is movably mounted on the connecting seat 313, and a self-resetting rotating shaft 316 that can move linearly along the length direction of the connecting frame 314 is symmetrically mounted on the connecting frame 314;

[0059] It should be noted that a double-layered limiting plate 317 is disposed on the inner side of the connecting frame 314 , and the double-layered limiting plate 317 limits the connecting seat 313 from making a vertical linear motion inside the connecting frame 314 .

[0060] It also includes a first return spring 315 installed on the inner side of the connecting frame 314, and the self-reset shaft 316 is elastically blocked by the first return spring 315 in its moving direction;

[0061] Specifically, a square rod is symmetrically arranged on the inner side of the connecting frame 314, the first return spring 315 is sleeved on the square rod, and the self-reset shaft 316 can move linearly along the square rod. When the self-reset shafts 316 move away from each other, the first return spring 315 is compressed.

[0062] A pleating sheet 311 is installed on the rotating shaft of each self-resetting rotating shaft 316 , and the pleating sheet 311 corresponds to the pleating groove 35 in a vertical state.

[0063] The bottom of the connecting frame 314 is symmetrically fixed with an electromagnetic chuck 318 and a baffle 3110 extending to the lower side of the electromagnetic chuck 318;

[0064] A double-layer limiting plate 319 is rotatably mounted on each pleating plate 311 . When the electromagnetic suction cup 318 is energized, the double-layer limiting plate 319 is driven to rotate under the action of magnetic force and engages with the corresponding blocking plate 3110 to limit the rotation of the pleating plate 311 .

[0065] During the first crimping process, the electromagnetic suction cup 318 is energized to generate magnetic force, causing the double-layer limiting plate 319 to be adsorbed on the electromagnetic suction cup 318 and engage with the blocking plate 3110 at the same time. Due to the fixing effect of the blocking plate 3110, the crimping plate 311 is prevented from rotating, thereby ensuring the accuracy of the first crimping process.

[0066] The bottom of the connecting seat 313 has a guide rod that penetrates the connecting frame 314 downward, and the guide rod is sleeved with a second return spring 3111. During the cutting and first crimping process, the connecting seat 313 can be moved inside the double-layer limit plate 317 through the crimping sheet 311 to form a buffer process.

[0067] Combination Figure 7 As shown, both sides of the pleating plate 34 are provided with obliquely extending push rods 39, and the sides of the pleating sheets 311 close to each other are provided with notches 312 corresponding to the push rods 39;

[0068] When the pleating plate 34 moves linearly, the push rod 39 cooperates with the notch 312 to make the pleating sheet 311 rotate around the self-resetting shaft 316 .

[0069] After the first pleating, the pleating mechanism 31 is in a compressed state and cannot directly perform the second pleating process. Therefore, the reset effect of the second reset spring 3111 is used to control the first driving cylinder 22 to drive the pleating mechanism 31 to move upward, so as to prevent the pleating mechanism 31 from completely separating from the gauze strip and prevent the gauze strip from being unable to separate from the pleating sheet 311 during the second pleating process, thereby maintaining the first pleating state of the gauze strip, and then use the second driving cylinder 33 to drive the pleating plate 34 to move, and then push the gauze strip into During the compression groove 37, the push rod 39 cooperates with the notch 312 to make the pleating sheet 311 rotate around the self-resetting shaft 316 while compressing the first reset spring 315, making it distributed in an eight-shaped shape, thereby facilitating the gauze strip to separate from the pleating sheet 311, thereby improving the degree of automation of the pleating process. When the pleating plate 34 pushes the gauze strip into the compression groove 37, the second pleating process is completed to form a gauze block, which finally falls onto the surface of the conveying device 40 through the drop chute 38 and is conveyed to the packaging device 50 by the conveying device 40.

[0070] It should be noted that, during the second crimping process, the electromagnetic suction cup 318 is in a non-powered state, and the double-layer limiting piece 319 is not engaged with the blocking piece 3110, so that the crimping piece 311 can rotate freely.

[0071] A packaging device 50, the packaging device 50 is used to package the folded gauze block;

[0072] The conveying device 40 is arranged at the lower side of the folding device 30 and is used for conveying the folded gauze block to the feed port of the packaging device 50.

[0073] Reference Figure 2 As shown, the packaging device 50 includes a rack housing 51 installed on one side of the conveying device 40, and a first packaging film roll 52, a second packaging film roll 55, and a first guide roller 53 and a second guide roller 54 for guiding the second packaging film roll 55 and the first packaging film roll 52 to form a double-layer film structure are arranged on the rack housing 51;

[0074] The second feeding roller 59 for conveying the second packaging film roll 55 is used to convey the second packaging film roll 55 while butting the folded gauze block so that the gauze block enters between the double-layer film structure;

[0075] The outlet of the rack housing 51 is provided with a packaging element 57 located at the upper and lower sides of the double-layer membrane, and a third driving cylinder 56 driving the packaging element 57 to perform linear motion;

[0076] When the third driving cylinder 56 drives the packaging element 57 to perform a closing movement, the double-layer film structure with the gauze block can be partially packaged to form an independent packaging unit;

[0077] The device further comprises a third feeding roller member 58, which is used for conveying the independent packaging units.

[0078] Combination Figure 3 As shown, the packaging element 57 includes a return heat sealing device 572 fixed to the end of the piston rod of the third driving cylinder 56 and a plurality of tie pieces 571 distributed around the return heat sealing device 572. The return heat sealing device 572 is used to heat the packaging element 57 and the second packaging film roll 55 to form an independent packaging unit, and the tie pieces 571 are used to provide tearing parts between adjacent packaging units, which is conducive to the separation of the packaging units later.

[0079] The specific bagging process is as follows: the gauze block is conveyed to the second feeding roller 59 by the conveying device 40, and the gauze block is placed on the surface of the second packaging film roll 55 by utilizing its conveying effect. The first packaging film roll 52 is covered on the surface of the gauze block by the third feeding roller 58, and then the packaging elements 57 are coordinated with each other by the third driving cylinder 56 to iron and package the second feeding roller 59 and the second packaging film roll 55 to form an independent packaging unit. The continuous packaging units are conveyed out by the third feeding roller 58 to complete the unloading.
