[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Reference Figure 1-3 According to one embodiment of the present invention, a film recycling and reprocessing device is provided, including a body 1. The body 1 is provided with a film splitting mechanism 2 and a reprocessing mechanism 3. A transport mechanism is provided between the film splitting mechanism 2 and the reprocessing mechanism 3. The film splitting mechanism 2 includes a sleeve 21 and a plurality of cutting blades 22. The cutting blades 22 are arranged at equal angles around the sleeve 21. The body 1 is provided with a power mechanism that drives the cutting blades 22 to move synchronously. The reprocessing mechanism 3 includes a melting tube 31. A condensation box 32 is provided at the output end of the melting tube 31. A winding mechanism 34 is fixedly connected to the body 1. A shearing mechanism 33 is provided at the output end of the winding mechanism 34.
[0038] Specifically, the EVA film to be disassembled is manually placed as follows: Figure 13 As shown, the sleeve 21 transports the EVA film to the film splitting mechanism 2. Several cutting blades 22 cut the EVA film. The cut EVA film is then transported to the reprocessing mechanism 3 via the transport mechanism for remelting and re-condensation into EVA glue lines. Finally, it is cut into glue particles by the shearing mechanism 33.
[0039] refer to Figure 4 and Figure 5 A lead screw 211 is rotatably connected inside the sleeve 21, and a threaded block 214 is threadedly connected to the lead screw 211. The sleeve 21 has a sliding groove 212 with opposite positions, and a tensioning block 215 is slidably connected to the sliding groove 212. The tensioning block 215 is fixedly connected to the threaded block 214. One end of the lead screw 211 passes through the machine body 1 and is fixedly connected to a first pulley 216. One end of the lead screw 211 is provided with a positioning block 213. The tensioning block 215 has a groove with one side open. An L-shaped block 217 is rotatably connected inside the groove. An iron block is installed on one end of the L-shaped block 217, and the other end is connected to the groove through a return spring. A first electromagnet 219 is fixedly connected inside the groove, and a limit block 218 is fixedly connected inside the groove.
[0040] Specifically, the lead screw 211 rotates under the action of the first pulley 216, and the tensioning block 215 moves horizontally. When the EVA film is fitted onto the sleeve 21, the tensioning block 215 is in a loose state, that is, the first electromagnet 219 is de-energized, and the L-shaped block 217 abuts against the limiting block 218 under the action of the return spring. When the operator presses the foot switch, the motor controls the first pulley 216 to rotate, causing the tensioning block 215 to move to one side of the first pulley 216. At this time, the tensioning block 215 is in a tensioned state, that is, the first electromagnet 219 is energized to generate a suction force, lifting one end of the L-shaped block 217, so that the core of the EVA film at one end of the L-shaped block 217 abuts.
[0041] refer to Figure 3 , Figure 4 , Figure 7 and Figure 8The cutting tool 22 includes a mounting shell 221. Both ends of the mounting shell 221 are fixedly connected to columns 224 that are slidably connected to the waist slots. The mounting shell 221 is rotatably connected to several blades 222. A drive box 223 is provided on one side of the mounting shell 221. Several meshing first gears are provided inside the drive box 223. Each first gear has a drive shaft, which is fixedly connected to the center of the blades 222. A first motor 225 is fixedly connected to the drive box 223 to drive one of the first gears to rotate. The top of the machine body 1 has a feed inlet 4. The inner wall of the side where the feed inlet 4 is located and the opposite inner wall both have cross-shaped waist slots. The waist slots without the feed inlet 4 penetrate the inner wall of the machine body 1. A rotating disk 23 is provided between the machine body 1 and the first pulley 216. The rotating disk 23 has several arc-shaped grooves 231. The column 224 at one end of the mounting shell 221 is slidably connected to the arc-shaped grooves 231. A ring gear is fixedly connected to the side of the rotating disk 23.
[0042] Specifically, since the inner walls on both sides of the top of the machine body 1 and the sides of the mounting shell 221 are rectangular / waist-shaped in the waist hole groove, the mounting shell 221 is prevented from rotating. When the rotating disk 23 rotates, the arc groove 231 and the column 224 move relative to each other. However, under the waist hole groove, all the cutting tools 22 move synchronously. The machine body 1 is fixedly connected to a second motor 24, and the output end of the second motor 24 is fixedly connected to a second pulley. The second pulley and the first pulley 216 are connected by belt drive. The machine body 1 is fixedly connected to a third motor 25, and the output end of the third motor 25 is equipped with a second gear. The first gear meshes with the ring gear.
[0043] The first motor 225 starts and drives all the blades 222 to rotate via the drive box 223.
[0044] refer to Figure 9 The transport mechanism includes a cavity 5 located below the film splitting mechanism 2. A pair of crushing rollers 51 are rotatably connected inside the cavity 5. A fourth motor 52 that drives the crushing rollers 51 to rotate is fixedly connected to the machine body 1. A spiral transport rod 53 is rotatably connected to the bottom of the cavity 5. A transport shell 55 is fixedly connected to the machine body 1. One end of the spiral transport rod 53 is located inside the transport shell 55. A fifth motor 54 that drives the spiral transport rod 53 to rotate is fixedly connected to the transport shell 55.
[0045] Specifically, the crushing roller 51 is a long roller with several grooves. Cutting blades are installed in the grooves. The blades of the cutting blades on the two crushing rollers 51 contact each other to form a shearing force. The two crushing rollers 51 rotate in opposite directions. The EVA film is crushed by the cutting blades. The crushed EVA film is transported into the melting tube 31 by the spiral conveyor rod 53.
[0046] refer to Figure 10 and Figure 11 The melting tube 31 is connected to the transport shell 55. The melting tube 31 is divided into a melting section and a filling section. The melting tube 31 is inclined. The melting section is equipped with a breathing solenoid valve 311. The filling section is slidably connected to a push block 312. The melting tube 31 is fixedly connected to an electric push rod 313 that drives the push block 312 to move. The breathing solenoid valve 311 includes a valve body 314. The valve body 314 is provided with an air passage 315, which is connected to the melting section. The valve body 314 is slidably connected to a sealing cover 316. A return spring is provided between the sealing cover 316 and the valve body 314. The valve body 314 is equipped with a second electromagnet. The bottom of the condensation box 32 is provided with a water inlet and the top is provided with a water outlet.
[0047] Specifically, the melting section is equipped with several heating modules. The electric push rod 313 reciprocates to push the push block 312, causing the push block 312 to move back and forth within the melting tube 31. Since the push block 312 has a certain sealing property in contact with the melting section and the filling section, when the push block 312 pushes back, the air in the melting section will decrease, and the melted adhesive will flow backward. In order to ensure a stable output of the adhesive line, the melting tube 31 is tilted and equipped with the breathing solenoid valve 311. When the second solenoid valve is energized, the sealing cover 316 seals the air passage 315. Thus, the adhesive enters the output end under the action of the push block 312, and the condensing box 32 condenses the adhesive into an adhesive line.
[0048] refer to Figure 1 , Figure 2 and Figure 13The winding mechanism 34 has a guide wheel at its input end and a pair of output wheels at its output end. The guide wheel and the output wheels are positioned between two flat plates, which are connected by push rods. The machine body 1 is fixedly connected to one of the flat plates, and a fifth motor 54 for driving the output wheels is fixedly connected to the other flat plate. The shearing mechanism 33 includes a housing 331 fixedly connected to and disposed on the machine body 1. The housing 331 has symmetrically positioned air chambers 332. Air blocks 333 are slidably connected in the air chambers 332. A shearing blade 335 is fixedly connected to the air blocks 333. A gas pipe 334 is provided on the inner wall of the air chambers 332 and is connected to an air pump.
[0049] Specifically, the adhesive line has two power sources: one is the pushing force of the pusher 312 during the adhesive pushing process, and the other is the traction force of the output wheel. The two output wheels press the adhesive line tightly, thus applying traction force to the adhesive line. The shearing mechanism 33 periodically changes the air pressure in the air chamber 332, causing the two shearing blades 335 to move relative to each other to shear the adhesive line.
[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
