Description

Technical Field

[0001] The invention relates to the technical field of packaging film winding, in particular to a winding device for packaging film production. Background Art

[0002] Packaging film mainly refers to the film used for packaging articles, usually including polyethylene film, biaxially oriented polyester film (BOPET), BOPP film and CPP film, etc., which are mainly used for the packaging of food, medicine and textiles.

[0003] At present, the packaging film needs to go through multiple rollers for aging treatment during the process from production to winding. During this process, there will be a certain amount of dust in the air in the production site. Since the packaging film will generate static electricity on its surface after continuous rolling, the dust particles in the air will be adsorbed on the surface of the film. Once the particles increase on the surface of the film, the particles may cause the film to slip when it is wound by the winding roller. In severe cases, the film may break due to sliding. Summary of the invention

[0007] The support transmission mechanism includes a first support frame, a pressure-bearing assembly, and two grounded conductive members;

[0008] The dust exhaust mechanism is installed on the first support frame and is used to absorb dust particles;

[0013] The extended guide rod is penetrated to one end of the inner side of the cross rail and is installed with a sleeve, and the auxiliary pressure gear shaft is movably installed in the sleeve.

[0014] In a preferred example, the present invention can be further configured as follows: the pressure-bearing assembly includes a second support frame installed outside the cross rail, a chassis installed inside the second support frame, a motor installed inside the chassis, and a first chain drivingly connected to the motor;

[0015] One of the grounding conductive members is installed in the first support frame, and the other grounding conductive member is installed in the second support frame.

[0016] In a preferred example, the present invention can be further configured as follows: the dust exhaust mechanism includes a clamp, a bellows installed on the clamp, and two switching air pipes connected to the bellows.

[0017] In a preferred example, the present invention can be further configured as follows: the wind box is composed of a fan, a chassis, and two ducts installed on the chassis.

[0018] In a preferred example, the present invention can be further configured as follows: the film material limiting mechanism further includes two cushions;

[0019] The two cushions are movably mounted in the two sets of reinforced shells respectively, and holes are provided inside the cushions;

[0020] A tie screw rod movably installed in the hole and a spring arranged outside the tie screw rod.

[0023] In a preferred example, the present invention can be further configured as follows: the membrane material dust removal mechanism also includes a filter bin, and a filter screen is installed in the end pipe at the inner end of the filter bin.

[0029] 2. The present invention provides two symmetrically distributed grounded conductive members at both ends of the two rolled tubes. When static electricity is generated by the rolling of the equipment during the process of stretching and winding the packaging film, the two rolled tubes are unimpededly attached to the packaging film, and the static electricity is eventually transferred from the two rolled tubes to the two grounded conductive members. This ensures that the static electricity of the packaging film is removed before winding, thereby reducing the problem of film rolling and folding due to static electricity.

[0046] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0047] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0048] A winding device for producing packaging films provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0049] Embodiment 1: Combination Figure 1-Figure 11 As shown, the present invention provides a winding device for packaging film production, including a dust exhaust mechanism 200 and a supporting transmission mechanism 100, a film material limiting mechanism 300 installed on the supporting transmission mechanism 100, and a film material dust removal mechanism 400 installed on the film material limiting mechanism 300, and the dust exhaust mechanism 200 is installed on the supporting transmission mechanism 100.

[0050] The support transmission mechanism 100 includes a first support frame 110, a pressure-bearing assembly 120, a grounding conductive member 130, a cross rail 140, an extended guide rod 150, a tension spring 160 and a pressure-assisting gear shaft 170, and the pressure-bearing assembly 120 also includes a second support frame 121, a chassis 122, a motor 123 and a first chain 124. The dust exhaust mechanism 200 includes a clamp 210, a bellows 220 and a switching air pipe 230. The film material limiting mechanism 300 includes a reinforced shell 310, a guide tube 320, a gasket 330, a positioning screw 340 and a spring 350. The film material dust removal mechanism 400 includes a first column head 410, a second column head 420, a third column head 430, a second chain 440, a bearing 450, a filter bin 460, a conductive assembly 470, a pole 480 and a rolled pipe fitting 490.

[0051] The support transmission mechanism 100 includes a first support frame 110, a pressure-bearing assembly 120, and two grounded conductive members 130;

[0052] The dust removal mechanism 200 is installed on the first support frame 110 and is used to absorb dust particles;

[0053] The dust exhaust mechanism 200 includes a fixture 210, a bellows 220 mounted on the fixture 210, and two transfer air pipes 230 connected to the bellows 220. The bellows 220 is composed of a fan, a chassis, and two ducts mounted on the chassis.

[0054] The film material limiting mechanism 300 includes four sets of reinforced housings 310 and flow guide pipes 320 installed in two adjacent reinforced housings 310;

[0055] The film material dust removal mechanism 400 includes two first column heads 410, two rolling tubes 490 movably mounted outside the two first column heads 410, a second column head 420 mounted on one of the rolling tubes 490, and a third column head 430 mounted on the other rolling tube 490;

[0056] A pole 480 is disposed in the middle of the inner cavity of the rolled tube 490 .

[0057] During the process of making and winding the packaging film, dust will be generated in the air in the factory due to the movement of pedestrians. At the same time, heat will be generated after the equipment continues to run. With the colloid of cold and hot air flows, a certain micro-airflow will be formed around the packaging film, which will cause the particles floating in the air in the factory to approach the packaging film along the airflow. Due to the repeated rolling and aging treatment of the packaging film by the pressure roller, static electricity will be generated on the surface of the packaging film, which will cause the particles in the air to be adsorbed on the surface of the packaging film, and then the winding roller will cause the packaging film to slip due to the interference of the particles. In severe cases, the packaging film will be too slippery and wrinkled or ribbed.

[0058] When the device is in use, two rolling tubes 490 are pre-arranged on one side of the winding roller. When the packaging film passes through the gap between the two rolling tubes 490 and is wound onto the winding roller, the two pre-adjusted rolling tubes 490 can be attached to the top and bottom surfaces of the packaging film without hindrance. As the two rolling tubes 490 are driven, the particles adsorbed on the packaging film can be sucked in by the airflow generated in the notches of the two rolling tubes 490. When the particles are separated from the surface of the packaging film, they will eventually be adsorbed on the two energized poles 480 along the direction of the airflow. The device can clean the particles on the surface of the packaging film while preventing the cleaned particles from re-accumulating on the packaging film near the winding roller.

[0059] In addition, two grounding conductive members 130 are respectively provided at both ends of the two rolled tubes 490. When the static electricity on the packaging film is transmitted to the two rolled tubes 490, it will eventually be transmitted from the two grounding conductive members 130 to the ground wire along the conduction of the two rolled tubes 490, thereby ensuring that the device can perform a comprehensive cleaning process on the rolled packaging film, thereby avoiding the problem of ribs and wrinkles on the packaging film caused by particulate matter or static electricity.

[0060] Embodiment 2: Combination Figure 4-Figure 11 As shown, on the basis of the first embodiment, the support transmission mechanism 100 further includes a cross rail 140, an extended guide rod 150 movably mounted inside the cross rail 140, a pressure-assisting gear shaft 170 movably mounted inside the extended guide rod 150, and a tension spring 160 disposed on the extended guide rod 150;

[0061] One end of the extended guide rod 150 that passes through the inner side of the cross rail 140 is installed with a sleeve, and the auxiliary pressure gear shaft 170 is movably installed in the sleeve;

[0062] The pressure-bearing assembly 120 includes a second support frame 121 installed outside the cross rail 140, a chassis 122 installed inside the second support frame 121, a motor 123 installed inside the chassis 122, and a first chain 124 drivingly connected to the motor 123;

[0063] One of the grounding conductive members 130 is installed in the first supporting frame 110 , and the other grounding conductive member 130 is installed in the second supporting frame 121 .

[0064] The cross rail 140 is fixedly installed in the cross groove on one side of the second support frame 121, and the extended guide rod 150 is movably installed in the cross rail 140. The tension spring 160 arranged outside the extended guide rod 150 provides elastic supporting force for the pressure-assisting gear shaft 170. At this time, the pressure-assisting gear shaft 170 movably installed in the inner end sleeve of the extended guide rod 150 can provide a tightening adjustment force for the transmission of the second chain 440. As the two rolling tube fittings 490 approach the contraction of the packaging film, the second chain 440 that is stretched outward by the pressure-assisting gear shaft 170 can be tightened in coordination with the contraction of the second column head 420 and the third column head 430. At this time, the two rolling tube fittings 490 can rotate along the top and bottom surfaces of the packaging film, and the airflow formed in the two rolling tube fittings 490 can attract the particulate matter on the packaging film, thereby continuously absorbing the particulate matter adsorbed on the packaging film.

[0065] Example 3: Combination Figure 4 and Fig.10 As shown, based on the first embodiment, the film material limiting mechanism 300 further includes two cushions 330;

[0066] The two cushions 330 are movably installed in the two sets of reinforced shells 310, and holes are opened inside the cushions 330;

[0067] A locking screw 340 movably mounted in the hole and a spring 350 disposed outside the locking screw 340;

[0068] Two nuts are connected to the two threaded sections at the top and bottom of the positioning screw 340 respectively.

[0069] Use a wrench or an electric wrench to adjust the two nuts on the two threaded sections of the binding screw 340. As the two nuts shrink along the two threaded sections, the two gaskets 330 can approach each other, and the spring 350 arranged on the outside of the binding screw 340 can provide a stable elastic supporting force for the two gaskets 330. By changing the gap between the two gaskets 330, the two adjacent groups of reinforcing shells 310 will drive the two first column heads 410 and the two rolled tubes 490 to approach each other, thereby enabling adaptive adjustment of packaging films of different thicknesses.

[0070] Embodiment 4: Combination Figure 3-Figure 11 As shown, based on the first embodiment, the film material dust removal mechanism 400 further includes four groups of bearings 450, wherein two groups of bearings 450 are installed outside the two first column heads 410, and the other two groups of bearings 450 are respectively installed outside the second column head 420 and the third column head 430 and are transmission-connected to the second chains 440 respectively installed outside the second column head 420 and the third column head 430;

[0071] The membrane material dust removal mechanism 400 also includes a filter bin 460, and a filter screen is installed in the end pipe at the inner end of the filter bin 460;

[0072] The film material dust removal mechanism 400 further includes a conductive component 470;

[0073] The conductive assembly 470 is composed of an L-shaped conductive plate, two gaskets, and a flat wire connected to the two gaskets, and the two gaskets are installed outside two of the bearings 450;

[0074] One end of the pole 480 is fixedly mounted on the L-shaped conductive plate.

[0075] By connecting the wire of the whip piece in the conductive component 470 to an external power supply and connecting the two grounded conductive members 130 to the ground wire, when the second column head 420 and the third column head 430 drive the two rolled tube fittings 490 to rotate, the conductive component 470 installed on the outside of the two first column heads 410 can supply power to the two poles 480. After the second column head 420 and the third column head 430 drive the two rolled tube fittings 490, the pole 480 that is stationary and located in the middle of the inner cavity of the rolled tube fitting 490 can attract particulate matter in the airflow. The two grounded conductive members 130 are movably installed on the outside of the two rolled tube fittings 490. After the static electricity on the packaging film is transferred to the rolled tube fitting 490, the two grounded conductive members 130 can quickly release the static electricity, thereby reducing the interference of static electricity on the winding of the packaging film.

[0076] The working principle and use process of the present invention are as follows: the wire in the conductive component 470 is connected to the external power supply in advance, and the end posts at the bottom of the two grounded conductive members 130 are connected to the ground wire at the same time, and then the two nuts on the two threaded sections of the tie screw 340 are adjusted. As the two nuts shrink along the threaded sections, the two gaskets 330 will drive the two groups of reinforced shells 310 to approach each other, wherein the two groups of reinforced shells 310 will drive the two first column heads 410 to approach each other, and the other two groups of reinforced shells 310 will drive the second column heads 420 and the third column heads 430 to approach each other. At this time, the two groups of reinforced shells 310 installed on one first column head are connected to each other. A rolled tube 490 on the first column 410 and the second column 420 and another rolled tube 490 installed on the other first column 410 and the third column 430 will be tightened toward the top and bottom surfaces of the packaging film until the two rolled tubes 490 are completely attached to the packaging film. When the motor 123 is started and runs, the gear on the internal transmission shaft will drive the first chain 124, and the other end of the first chain 124 will drive the third column 430, and two gear plates are installed on the outside of the third column 430, and one gear plate is installed on the outside of the second column 420. 30 rotation, the second chain 440 set on one of the gear plates in the third column head 430 will drive the second column head 420, and at this time the two roller-pressed pipe fittings 490 can rotate unhindered along the top and bottom surfaces of the packaging film, and as the packaging film is continuously delivered, when there are conductive particles on the film body, the particles will be sucked out from the grooves inside the two roller-pressed pipe fittings 490, and finally the conductive particles will be adsorbed when the two poles 480 are powered on, and the air will be exhausted outwards by the bellows 220. The pipes at the top and bottom of the bellows 220 can cooperate with the two adapter air pipes 230 to The air inside the two first column heads 410 is discharged outward, while the particles adsorbed on the outside of the pole 480 can be continuously discharged outward. When the packaging film generates static electricity due to the conductive particles, the two rolled tubes 490 are fully fitted with both sides of the packaging film, and the static electricity can be quickly drained by the two rolled tubes 490 and finally released to the ground from the two grounded conductive parts 130. At this time, the device can remove the static electricity on the surface of the packaging film and clean the particles attached to the packaging film during the production process to avoid excessive particles on the surface of the packaging film causing slippage during winding, and then the problem of rib cracking occurs.

[0077] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
