DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The following is a description of the fixed-distance cutting and edge-sealing device for producing packaging bags according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0024] like Figure 1 - Figure 5 As shown, the packaging bag production fixed-distance cutting and edge-sealing device of the embodiment of the utility model comprises a workbench 1, a bag placing part 2 and an edge-sealing mechanism 3, wherein the bag placing part 2 is fixedly installed on the workbench 1. The edge-sealing mechanism 3 is fixedly arranged on the workbench 1, and the edge-sealing mechanism 3 is located on one side of the workbench 1.

[0025] The edge sealing mechanism 3 includes a support frame 31, a rotating cylinder 32, a plurality of exhaust grooves 33, a driving motor 34, an exhaust hood 35, an exhaust fan 36, a plurality of exhaust holes 37, a rotating roller 310, an edge sealing assembly 38 and a spacing assembly 39; the support frame 31 is fixedly arranged on the workbench 1; the rotating cylinder 32 is rotatably arranged on the support frame 31, and the driving motor 34 is fixedly installed on the support frame 31.

[0026] It should be noted that when the edge sealing component 38 is processing the packaging bag, the output end of its drive motor 34 will no longer rotate. Only when the edge sealing component 38 completes its work and resets, the drive motor 34 can continue to work, that is, the drive motor 34 and the edge sealing component 38 cannot run at the same time.

[0027] A plurality of air extraction grooves 33 are respectively provided on the rotating cylinder 32, and the plurality of air extraction grooves 33 are not connected; an air extraction hood 35 is fixedly mounted on the support frame 31, and an exhaust fan 36 is fixedly arranged on the air extraction hood 35. A plurality of air extraction holes 37 are respectively provided on the rotating cylinder 32, and the plurality of air extraction holes 37 are respectively connected to the corresponding air extraction grooves 33.

[0028] It is understandable that when in use, the exhaust fan 36 will extract the air inside the exhaust hood 35, and the exhaust hood 35 is connected to the exhaust groove 33 through the exhaust hole 37, so that when a negative pressure is generated inside the exhaust hood 35, the inside of the exhaust groove 33 can be extracted through the exhaust hole 37, so that the inside of the exhaust groove 33 reaches a negative pressure, and then the exhaust groove 33 can be used to adsorb the packaging bags on the surface of the rotating cylinder 32.

[0029] The rotating rod 310 is installed on the supporting frame 31 .

[0030] It should be noted that the function of the rotating roller 310 is to change the moving path of the packaging bag so that the packaging bag can contact the packaging bag from the bottom of the rotating cylinder 32, thereby increasing the contact area between the rotating cylinder 32 and the packaging bag, and then providing a more stable pulling force for the packaging bag when the rotating cylinder 32 rotates.

[0031] The edge banding assembly 38 is fixedly arranged on the support frame 31. The distance assembly 39 is fixedly arranged on the workbench 1.

[0032] Specifically, in the actual operation process, continuous production of packaging bags cannot be achieved. Based on this, by setting up the edge sealing mechanism 3, before use, first control the operation of the exhaust fan 36, then place the packaging bag to be processed on the bag placing piece 2, and then manually pass the packaging bag to be processed through the bottom of the rotating roller 310 and fit it with the rotating cylinder 32 close to the side of the bag placing piece 2. Due to the operation of the exhaust fan 36, a negative pressure is generated inside the exhaust groove 33 to adsorb the packaging bag to be processed that is attached to the surface of the rotating cylinder 32, so that the packaging bag is attached to the surface of the rotating cylinder 32.

[0033] After completing the above work, the drive motor 34 is controlled to rotate the output end of the drive motor 34. The rotation of the output end of the drive motor 34 will drive the rotating drum 32 to rotate, so that the rotating drum 32 pulls the packaging bag. During the rotation of the rotating drum 32, the packaging bag can be sealed and cut by the edge sealing component 38. After cutting, when the packaging bag rotates to the other side of the exhaust hood 35 under the action of the rotating drum 32, the exhaust groove 33 loses its adsorption force, which will cause the processed packaging bag to fall off automatically, thereby completing the continuous production of the packaging bag.

[0034] The packaging bag is adsorbed by utilizing the suction grooves 33 on the surface of the rotating cylinder 32 so that the packaging bag and the rotating cylinder 32 rotate synchronously. The edge sealing assembly 38 is utilized to perform edge sealing and cutting during rotation. The continuous rotation of the rotating cylinder 32 can achieve continuous production of the packaging bag, thereby solving the problem of the existing cutting and edge sealing being performed separately, which makes it impossible to ensure the stability of the cut end of the packaging bag when the cut packaging bag is transported, making it easy for the cut end of the packaging bag to be misaligned and affecting the quality of the packaging bag.

[0035] In one embodiment of the present invention, Figure 2 As shown, the suction hood 35 is semicircular, and the suction hood 35 is in contact with the rotating drum 32.

[0036] It should be noted that the semicircular exhaust hood 35 is designed so that after the packaging bags are cut, that is, when the rotating cylinder 32 rotates to the other side of the exhaust hood 35, the exhaust groove 33 on the other side of the exhaust hood 35 no longer generates adsorption force, thereby allowing the processed packaging bags to fall off automatically.

[0037] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the edge banding assembly 38 includes a fixing frame 381 , an electric telescopic rod 382 , a connecting plate 383 , an edge banding piece 384 and a cutting piece 385 , wherein the fixing frame 381 is fixedly mounted on the supporting frame 31 .

[0038] It should be noted that the edge sealing member 384 and the cutting member 385 are symmetrically arranged on both sides of the connecting plate 383. When the connecting plate 383 contacts the top of the rotating cylinder 32, the edge sealing member 384 and the cutting member 385 contact the packaging bag at the corresponding position, thereby achieving the cutting and edge sealing of the packaging bag.

[0039] It should be noted that the edge sealing member 384 uses an electric heating rod to heat the packaging bag to perform thermoplastic edge sealing, and the cutting member 385 uses a reciprocating blade to cut the packaging bag.

[0040] The electric telescopic rod 382 is fixedly arranged on the fixing frame 381, and the connecting plate 383 is fixedly arranged on the electric telescopic rod 382. The edge sealing member 384 is fixedly arranged on the connecting plate 383, and the cutting member 385 is fixedly arranged on the connecting plate 383.

[0041] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the distance assembly 39 includes a synchronization rod 391, a plurality of first trigger rods 392, a plurality of second trigger rods 393, a plurality of third trigger rods 394, a sliding plate 395 and a trigger switch 396, wherein the synchronization rod 391 is fixedly mounted on the rotating cylinder 32.

[0042] It can be understood that since the number of the first trigger rod 392, the second trigger rod 393 and the third trigger rod 394 are different, the lengths of the produced packaging bags are different. Therefore, the position of the trigger switch 396 can be adjusted so that the trigger switch 396 corresponds to different numbers of trigger rods to produce packaging bags of different lengths. When adjusting, the sliding plate 395 can be directly pushed. After pushing, the auxiliary positioning member can be used to position the moved sliding plate 395.

[0043] A plurality of first trigger rods 392, a plurality of second trigger rods 393 and a plurality of third trigger rods 394 are all fixed on the surface of the synchronization rod 391. The sliding plate 395 is slidably mounted inside the workbench 1, and the trigger switch 396 is mounted on the sliding plate 395.

[0044] Specifically, in actual use, the spacing component 39 and the edge sealing component 38 are used to cut and seal the packaging bag. The specific working principle is: when the edge sealing mechanism 3 drives the packaging bag to rotate, it will drive the synchronization rod 391 to rotate. The rotation of the synchronization rod 391 will drive the first trigger rod 392, the second trigger rod 393 and the third trigger rod 394 to rotate. During rotation, if the first trigger rod 392 comes into contact with the trigger switch 396, the output end of the drive motor 34 controlled by the trigger switch 396 will no longer rotate, and the output end of the electric telescopic rod 382 will move downward, and then the electric telescopic rod 382 will drive the edge sealing member 384 and the cutting member 385 to cut and seal the packaging bag.

[0045] In one embodiment of the present invention, Figure 5 As shown, the number of the plurality of first trigger rods 392 , the number of the plurality of second trigger rods 393 , and the number of the plurality of third trigger rods 394 are different.

[0046] It should be noted that the number of the first trigger rod 392, the second trigger rod 393 and the third trigger rod 394 can be two, three, four, five, etc., which can be set as needed. Since edge sealing and cutting are achieved when the trigger rod contacts the trigger switch 396, the distance between two adjacent trigger rods is also the length of the packaging bag, which can be set according to actual conditions.

[0047] In summary, the fixed-distance cutting and edge-sealing device for producing packaging bags in the embodiment of the utility model utilizes the vacuum grooves on the surface of the rotating cylinder to adsorb the packaging bags, so that the packaging bags and the rotating cylinder rotate synchronously, and the edge-sealing components are utilized to perform edge sealing and cutting during rotation. The continuous rotation of the rotating cylinder can achieve continuous production of packaging bags, which solves the problem of existing cutting and edge-sealing being performed separately, so that when the cut packaging bags are conveyed, the stability of the cut end of the packaging bags cannot be guaranteed, which makes them easily misaligned and affects the quality of the packaging bags.
