In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or instance. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0033] Referring to Figures 1-9 , a roll bag pressing device for a woven bag hot cutting machine, comprising a frame 1, a connecting seat 21 is installed on the top of the frame 1, a winding roller 2 is arranged on the connecting seat 21, a rotatable pressing roller 3 is arranged above the winding roller 2, and a pressing assembly 4 is installed on the pressing roller 3 for adjusting the pressing position of the pressing roller 3; the pressing assembly 4 includes a mounting plate 41 rotatably connected to the end of the pressing roller 3 through a pin shaft, a sliding rod 42 is installed on the top of the mounting plate 41, a first slider 43 is fixed at the end of the sliding rod 42, the first slider 43 is slidably connected in a connecting cylinder 44, the connecting cylinder 44 is embedded and installed on the frame 1, a compression spring 45 is fixed on the top of the connecting cylinder 44, and an adjusting member is arranged at one end of the compression spring 45; a rotating plate 5 is arranged on one side of the pressing roller 3, and an electrostatic elimination assembly 6 is arranged at one end of the rotating plate 5 to guide the ion wind ejected by the electrostatic elimination assembly 6 when the rotating plate 5 is in a swinging state.

[0034] In the process of processing woven bags, the rolled woven bags are generally transferred to the conveying platform through unwinding, and then the woven bags are cut by the set hot cutting mechanism to obtain woven bags of suitable size, which is convenient for the subsequent processing of woven bags. Then, in the process of unwinding the woven bags, in order to improve the stability of the woven unwinding and eliminate the occurrence of wrinkles, a simple pressing roller is generally used in the prior art to limit the position to avoid the woven bags wound on the unwinding roller 2 from becoming loose. However, considering the actual operating state and according to the process requirements, when unwinding the woven bags of different sizes, due to the straight The diameters are different, the required elasticity is different, and the limiting effect is different, which is inconvenient to perform adaptive adjustment, and finally leads to unsatisfactory limiting effect, increased tension of the woven bag or sliding film phenomenon of the woven bag. Therefore, in the present scheme, the provided clamping assembly 4 cooperates with the clamping roller 3, and can be adaptively adjusted according to the diameter of the woven bag wound on the unwinding roller 2, so that the clamping roller 3 can better fit and contact the woven bag on the unwinding roller 2 to limit the position, give appropriate elastic supporting force, avoid the above situation, and improve the application range of the device. However, even in the case of clamping with the clamping roller 3, due to the clamping roller 3 and the The contact and friction on the surface of the woven bag can easily generate static electricity, which may absorb dust and foreign matter, affecting product quality, and further affecting the processing quality of subsequent hot cutting operations. For example, static electricity can interfere with the control system of the hot cutting machine, because modern hot cutting machines rely on precise electronic control to adjust the temperature of the heat source, cutting speed and other parameters. When static electricity exists, it may sense or interfere with these microelectronic signals, causing the control system to work unstably, thereby affecting the cutting accuracy and efficiency. In this solution, by setting up the static electricity removal component 6, ion wind can be generated and blown to the material-discharging extension part of the woven bag to perform static electricity elimination operation. When the static electricity is pressed, When component 4 is in contact with the pressure roller 3, it drives the pressure roller 3 to rotate synchronously to provide power, and then drives the rotating plate 5 to swing up and down, diverting the ion wind generated by the static electricity removal component 6, so that the static electricity can be removed from the woven bag and the pressure roller 3. At the same time, the blown wind can produce an auxiliary effect of cleaning dust and foreign matter. During the swinging process of the rotating plate 5, the air cushion component 7 can be driven to operate synchronously, blowing air to the bottom of the woven bag discharge part, forming convection with the ion wind sprayed from the top of the woven bag, forming a stable air cushion, reducing the shaking of the woven bag during the discharge process, and improving the stability of the woven bag transportation.

[0035] In a preferred embodiment, referring to Figure 4, the pressing assembly 4 includes a mounting plate 41 rotatably connected to the end of the pressing roller 3 through a pin shaft. A slide bar 42 is mounted on the top of the mounting plate 41. A first slider 43 is fixed to the end of the slide bar 42. The first slider 43 is slidably connected within a connecting cylinder 44. The connecting cylinder 44 is embedded and mounted on the frame 1. A compression spring 45 is fixed to the top of the connecting cylinder 44. One end of the compression spring 45 is provided with an adjusting member. The adjusting member includes an adjusting block 46 fixed to one end of the compression spring 45. The adjusting block 46 is slidably connected within the connecting cylinder 44. The top of the adjusting block 46 is rotatably connected to an adjusting screw 47 through a bearing. The adjusting screw 47 is threadedly connected to the inner wall of the top of the connecting cylinder 44.

[0036] With the above solution, the setting of the compression spring 45 presses the slide bar 42 at the bottom of the first slider 43 to move downward according to the elastic force of the compression spring 45, driving the surface of the pressing roller 3 to closely fit with the surface of the woven bag wound on the unwinding roller 2, thus achieving the effect of pressing and limiting. When the diameter of the woven bag wound on the unwinding roller 2 changes greatly and exceeds the elastic force of the compression spring 45, the staff can manually rotate the adjusting screw 47 to drive the adjusting block 46 to displace inside the connecting cylinder 44, and then adjust the initial position of the pressing roller 3, so that the pressing roller 3 fits better with the woven bag on the unwinding roller 2, ensuring that the pressing roller 3 is in a suitable pressing effect. Compared with the prior art of using only a pressure roller for limiting, its application range is wider.

[0037] In a preferred embodiment, referring to Figure 2 , Figure 5 , Figure 6 and Figure 7 , the static elimination assembly 6 includes a support plate 61 fixed to one side of the mounting plate 41. One end of the support plate 61 is fixed with a static eliminator 62. The bottom of the static eliminator 62 is connected with an air delivery pipe 63. The end of the air delivery pipe 63 is fixed with an exhaust hood 64. One end of the exhaust hood 64 is provided with a synchronizing member. The synchronizing member includes a fixing plate 65 fixed to one end of the exhaust hood 64. The surface of the fixing plate 65 is rotatably connected to a rotating shaft 66 through a bearing. One end of the rotating shaft 66 is connected to a transmission wheel 67 through a synchronous belt drive. One end of the transmission wheel 67 is fixedly connected to the pressing roller 3. The other end of the rotating shaft 66 is provided with a swinging member. The swinging member includes a rotating wheel 68 fixed to the other end of the rotating shaft 66. One side of the rotating wheel 68 is rotatably connected to a connecting rod 69 through a pin shaft. One end of the connecting rod 69 is rotatably connected to a cam 691 through a pin shaft. The center of the cam 691 is fixedly connected to the rotating plate 5.

[0038] With the above solution, the static eliminator 62 operates using an ion fan instead. The ion fan is powered on to generate ion wind, which is transported through the air duct 63 to the exhaust hood 64 and then ejected. The pressing roller 3 is in contact with the woven bag wound around the unwinding roller 2. As the woven bag is pulled, the unwinding roller 2 rotates, which in turn drives the pressing roller 3 to rotate. The rotation of the pressing roller 3 drives the rotating wheel 68 at one end of the rotating shaft 66, ultimately driving the rotating plate 5 to swing back and forth. Due to the swing of the rotating plate 5, when swinging upward, the ion wind coming out of the exhaust hood 64 is discharged from the top surface of the rotating plate 5 through the diversion of the rotating plate 5 and blows towards the pressing roller 3. The positive and negative ions generated by the ion wind neutralize the static electricity, thereby eliminating the static electricity generated on the surface of the pressing roller 3 due to contact friction with the woven bag. When the rotating plate 5 swings downward, the ion wind ejected from the exhaust hood 64 is blown towards the woven bag through the diversion of the rotating plate 5 to perform static elimination operation on the woven bag with static electricity generated by friction. The air outlet of the exhaust hood 64 points to the middle position between the pressing roller 3 and the woven bag wound on the unwinding roller 2. In the state where the rotating plate 5 does not swing, both the pressing roller 3 and the woven bag can obtain the static electricity elimination effect of the ion wind blowing. When the rotating plate 5 swings, the blown air flow can be guided, thus increasing the air blowing intensity of the ion wind and enabling good cleaning effect on some foreign matters adhered to the pressing roller 3 and the woven bag.

[0039] In a preferred embodiment, referring to Figure 9 , an air cushion assembly 7 is provided on the static elimination assembly 6. When the rotating plate 5 swings downward, it drives the air cushion assembly 7 to operate. The air cushion assembly 7 includes a rotating rod 71 fixed to one end of the rotating plate 5. The surface of the rotating rod 71 is rotatably connected to the exhaust hood 64 through a bearing. An extrusion plate 72 is fixed to the end of the rotating rod 71. A gas bag 73 is provided on one side of the extrusion plate 72. An installation block 74 is fixed to the end of the gas bag 73, and the installation block 74 is installed on one side surface of the exhaust hood 64. An air inlet pipe is provided on one side surface of the gas bag 73, and a one-way valve is provided at the air inlet pipe. A discharge pipe 75 is fixed to one side surface of the gas bag 73. The discharge pipe 75 is in an L shape, and jet heads 76 are arranged on the surface of the discharge pipe 75 at equal intervals. A one-way valve is provided at the connection between the discharge pipe 75 and the gas bag 73. The width of the rotating plate 5 is the same as the width of the woven bag wound on the unwinding roller 2. A diversion groove is provided on the rotating plate 5. An installation frame 8 is installed on the frame 1, and a tension roller 9 is rotatably connected to the surface of the installation frame 8 through a bearing.

[0040] With the above solution, when the rotating plate 5 swings downward, it drives the pressing plate 72 to press the airbag 73 at this time. The air in the airbag 73 is squeezed and conveyed to the exhaust pipe 75, and then ejected through a plurality of jet heads 76. Since the jet heads 76 are located at the bottom of the extended part of the woven bag feeding, they form convective air with the ionic wind ejected from the top of the woven bag, so as to stably support the extended and transported woven bag, avoid the woven bag from shaking during transportation, reduce the friction generated by the contact between the woven bag and other components, further improve the anti-static effect, and improve the stability of the woven bag transportation. A diversion groove is provided on the rotating plate 5 to make the ejection of the ionic wind smoother. Among them, the air inlet pipe and the one-way valve on the airbag 73 are not shown. In the preferred solution, one end of the air inlet pipe is connected to the airbag 73, and the other end penetrates through the exhaust hood 64 and is connected to the inside of the exhaust hood 64. In this way, the air flow ejected from the jet head 76 is also ionic wind, which can neutralize the static charges on both the upper and lower surfaces of the woven bag, making the static elimination effect more comprehensive, reducing the adsorption of dust by the woven bag during subsequent transportation, and improving the processing quality of the subsequent hot cutting of the woven bag.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
