[0026] Referring to Figures 1 to 4The utility model discloses a kind of double-side opening devices of cylindrical woven bag, including oppositely arranged baffle 100, rotating shaft 200, drive assembly 300, wiping assembly 400, heating assembly (not shown in the drawing), one accommodating space 110 is formed between two baffles 100, the accommodating space is equipped with opening 111 close to the edge of cylindrical woven bag.

[0027] Rotating shaft 200 is rotationally arranged on baffle 100, preferably, the two ends of rotating shaft 200 are rotationally arranged on the two baffles 100 respectively. A plurality of groups of hot cutters 210 are arranged on the outer peripheral wall of rotating shaft 200, the plurality of groups of hot cutters 210 are arranged along the axial direction of rotating shaft 200, and the central plane of the hot cutters 210 is parallel to the central plane of rotating shaft 200.

[0028] Drive assembly 300 is arranged in the accommodating space 110, and the drive assembly 300 is in transmission connection with the rotating shaft 200. When the drive assembly 300 works, the rotating shaft 200 is driven to rotate. Optionally, the drive assembly 300 can adopt a rotary cylinder, a rotary motor or the like power device.

[0029] The wiping assembly 400 is arranged on the baffle 100, and is used for wiping the melted substance adhered to the hot cutter 210. Specifically, the wiping assembly 400 comprises a first driver 410, a transmission member 420 arranged oppositely, and magnetic brushes 430 capable of being attracted to each other. The first driver 410 is fixedly arranged on the baffle 100. The transmission member 420 is in transmission connection with the first driver 410. The magnetic brushes 430 are movably arranged on the transmission member 420. The heating assembly is used for heating the hot cutter 210. Optionally, the first driver 410 can adopt a rotary cylinder, a rotary motor or the like power device.

[0030] In the embodiment, when one of the hot cutters 210 extends out of the opening 111 and abuts against the edge of the moving cylindrical woven bag, the hot cutter 210 heated by the heating assembly performs hot melt cutting on the cylindrical woven bag. When the hot cutter 210 is used for a period of time, the drive assembly 300 drives the rotating shaft 200 to rotate to a preset angle. At this time, the first driver 410 starts to work, and drives the magnetic brushes 430 to reciprocate along the length direction of the hot cutter 210 through the transmission member 420. Since the two magnetic brushes 430 can be attracted to each other, the two magnetic brushes 430 are clamped and pressed on the surface of the hot cutter 210. In this way, when the magnetic brushes 430 reciprocate, the melted substance on the surface of the hot cutter 210 can be removed. It should be noted that the surface of the general hot cutter 210 is not a complete plane, so the magnetic brushes 430 have a certain compressibility. In addition, the surface temperature of the hot cutter 210 is relatively high, so the part of the magnetic brushes 430 in contact with the surface of the hot cutter 210 needs to be made of high-temperature-resistant material.

[0031] In some embodiments of the utility model, as shown inFigure 3 As shown, the transmission member 420 comprises a screw rod 421 and a guide column 422, and the magnetic brush 430 is threadedly connected to the screw rod 421 and is slidingly arranged on the guide column 422. In this embodiment, when the screw rod 421 rotates, the magnetic brush 430 will slide on the guide column 422 due to the limiting action of the guide column 422, so that the magnetic brush 430 can reciprocate along the length direction of the hot cutting knife 210, thereby achieving the purpose of removing the melted material on the surface of the hot cutting knife 210.

[0032] In some embodiments of the present application, the magnetic brush 430 comprises a base 431 and high-temperature-resistant brush heads 432, the base 431 is threadedly connected to the screw rod 421, and the high-temperature-resistant brush heads 432 are movably arranged on the base 431, so that the hot cutting knife 210 of various sizes can be adapted. In addition, in order to improve the cleaning efficiency, a plastic dissolving agent such as acetone is impregnated on the high-temperature-resistant brush heads 432, and the plastic dissolving agent can dissolve the plastic hot melt adhesive.

[0033] In some embodiments of the present application, as shown in Figure 3 The base 431 is provided with a sliding column 4311, the high-temperature-resistant brush head 432 is provided with a plug-in interface 4321, the sliding column 4311 is slidingly plugged into the plug-in interface 4321, and an elastic member 433 is arranged between the plug-in interface 4321 and the sliding column 4311. In this way, the high-temperature-resistant brush head 432 can slide relative to the base 431, so that the distance between the two high-temperature-resistant brush heads 432 can be changed, thereby adapting to hot cutting knives 210 of various sizes.

[0034] In some embodiments of the present application, as shown in Figure 3 The elastic member 433 comprises a spring, the spring is sleeved on the sliding column 4311, and the two ends of the spring are fixedly connected with the base 431 and the bottom of the plug-in interface 4321, respectively. In use, the spring is always in a compressed state, so that the two high-temperature-resistant brush heads 432 are tightly clamped on the surface of the hot cutting knife 210, and when the hot cutting knife 210 of different sizes is adapted, the extensibility of the spring can ensure that the two high-temperature-resistant brush heads 432 are always tightly clamped on the surface of the hot cutting knife 210.

[0035] In some embodiments of the present application, as shown in Figure 4 The hot cutting knife 210 is provided with a receiving cavity 211, the hot cutting knife 210 is provided with a heat-conducting portion 212, the heating assembly comprises a coil 510 and a high-frequency induction heating machine, the coil 510 is fixedly arranged in the receiving cavity 211, the heat-conducting portion 212 is arranged in the coil 510, and the high-frequency induction heating machine is electrically connected with the coil 510.

[0036] In the embodiment, the high-frequency induction heating machine supplies high-frequency alternating current to the coil 510 when working, so that the coil 510 generates an alternating magnetic field, so that eddy current is generated inside the heat-conducting part 212, and then the heat-conducting part 212 is heated, and then the heat-conducting part 212 conducts heat to the blade of the hot cutting knife 210.

[0037] In some embodiments of the utility model, the outer surface of the hot cutting knife 210 is provided with a sticky-resistant coating (not shown in the drawings), which reduces the probability of the surface of the hot cutting knife 210 sticking to plastic melt.

[0038] In some embodiments of the utility model, preferably, the sticky-resistant coating is a Teflon coating. It should be noted that the Teflon coating has good non-stickiness, heat resistance, sliding property, moisture resistance, wear resistance and corrosion resistance, so the hot cutting performance of the hot cutting knife 210 can be improved.

[0039] In some embodiments of the utility model, the baffle 100 is inclined on one side along the conveying direction of the cylindrical woven bag, so that the separated and moved cylindrical woven bags can smoothly pass along the surface of the baffle 100, and to some extent, the phenomenon of transport jamming of the cylindrical woven bags can be avoided.

[0040] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
