After being highly integrated in the automated equipment, there are inconveniences in loading and unloading the PI film. For example, when changing materials, the entire mechanism must be disassembled before replacement. After the model of the material strip is changed, the replacement of the unwinding wheel and the winding wheel is also more troublesome. Summary of the invention

[0011] Furthermore, blocking blocks are provided on both sides of the inner frame, and locking components driven by a cylinder and capable of fastening the blocking blocks to prevent the inner frame from sliding are provided on both sides of the outer frame.

[0012] Furthermore, the locking assembly includes a fastener, which includes a V-shaped action part and a locking part integrally formed at one end of the action part, the locking part extends toward the outer bend of the action part, one end of the action part away from the locking part is hinged to the driving end of the cylinder, the middle part is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to the side of the cylinder facing the outer frame.

[0013] Furthermore, the rotating shafts at both ends of the receiving pulley are provided with the first gear, and the first gears of any two adjacent receiving pulleys facing each other are meshed with the same second gear.

DETAILED DESCRIPTION

[0036] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0037] like Figure 1-10 As shown, a multi-material belt 300 material collection and unloading mechanism includes an outer frame 100 and an inner frame 200 slidably arranged in the outer frame 100, and the inner frame 200 is provided with a plurality of unloading components 210, a plurality of tension components 220 and a plurality of receiving components 230 arranged side by side, wherein:

[0038] The material discharging assembly 210 includes a material discharging pulley 211 and first mounting seats 212 disposed on both sides of the material discharging pulley 211. The first mounting seats 212 are provided with inclined grooves 2121 for the rotating shaft of the material discharging pulley 211 to slide in and out.

[0039] The tension assembly 220 includes two first retaining rings 221 and a pressing wheel 222 pressing between the two first retaining rings 221. The two first retaining rings 221 of the plurality of tension assemblies 220 are adjustably mounted on the same first driving shaft 223.

[0040] The receiving assembly 230 includes a receiving pulley 231 and second mounting seats 232 disposed on both sides of the receiving pulley 231. The second mounting seats 232 are hook-shaped and limit the rotating shafts at both ends of the receiving pulley 231 therein. A first gear 233 is disposed on the rotating shaft of the receiving pulley 231. The receiving assembly 230 also includes a second driving shaft 234. A second gear 235 meshing with the first gear 233 of each receiving pulley 231 is disposed on the second driving shaft 234.

[0041] One end of the first drive shaft 223 and the second drive shaft 234 pass through a side wall of the inner frame 200 and are connected by a transmission belt. A third gear 224 is also provided on the end of the first drive shaft 223 passing through the inner frame 200. A motor 110 is provided on one side of the outer frame 100. The driving end of the motor 110 passes through the side wall of the outer frame 100 and is provided with a fourth gear 111. After the inner frame 200 slides into the outer frame 100, the third gear 224 can engage with the fourth gear 111.

[0042] Among them, based on the inclined groove 2121 of the first mounting seat 212 and the hook-shaped second mounting seat 232, the material discharge pulley 211 and the material collection pulley 231 can be directly inserted to complete the installation, so the replacement of the material discharge pulley 211 and the material collection pulley 231 is particularly convenient; through the sliding setting of the outer frame 100 and the inner frame 200, when loading and unloading, the inner frame 200 can be directly pulled out to expose the inner frame 200 to a wide space, which is convenient for loading and unloading; the motor 110 rotates the first drive shaft 223 and the second drive shaft 234 at the same time, and then drives multiple tension components 220 and material collection components 230 to work at the same time, while realizing unified feeding drive, a single material belt 300 can be replaced quickly and separately, which solves the risk of breaking the material belt 300 due to different tensioning forces when the diameters of different groups of material belts 300 are different when they are released and retracted; simplifying the control program improves feeding accuracy, is easy to operate, reduces production costs, and improves production efficiency.

[0043] Specifically, the rotating shafts at both ends of the receiving pulley 231 are provided with first gears 233, and the first gears 233 of any two adjacent receiving pulleys 231 facing each other are meshed with the same second gear 235. In this way, the driving force received by each receiving pulley 231 can be further made consistent, so that the control accuracy is improved.

[0044] In one embodiment, the pressure wheel 222 is connected between two connecting rods 225, the top ends of the two connecting rods 225 are connected to the mounting block 226, a cross bar 227 parallel to the first drive shaft 223 is spanned in the inner frame 200, and the mounting block 226 is mounted on the cross bar 227. The two connecting rods 225 are connected to the mounting block 226 through springs 228. Based on the springs 228 and the connecting rods 225, the pressure wheel 222 forms an elastic pressure on the material belt 300 on the first drive shaft 223; the cross bar 227 and the mounting block 226 are provided, so that the position of the pressure wheel 222 can be adjusted, and then, in combination with the first retaining ring 221 that can adjust the position, it can adapt to material belts 300 of different specifications. A hoop 229 that surrounds the first drive shaft 223 is fixed on one side of the first retaining ring 221, and the position of the first retaining ring 221 can be adjusted by adjusting the tightness of the hoop 229.

[0045] In one embodiment, a plurality of first tension shafts 240 are provided on the side facing each other of the unwinding assembly 210 and the tension assembly 220, and the coil pulled out from the unwinding pulley 211 crosses through the top or bottom of the plurality of first tension shafts 240. A plurality of second retaining rings 241 are provided on each first tension shaft 240, and the coil is enclosed between every two second retaining rings 241. A second tension shaft 250 is also provided on one side of the unwinding assembly 210 and the receiving assembly 230, respectively, and a through slot 251 is provided in the second tension shaft 250 for the coil to pass through. The through groove 251 of the first tension shaft 240 and the second tension shaft 250 can increase the tension of the material belt 300 during the transmission process. At the same time, when other equipment takes material from the material belt 300 (the material is attached to the material belt 300), the material can be taken from the position between the first tension shaft 240 next to the discharge component 210 and the first tension shaft 240 next to the tension component 220. Due to the presence of multiple first tension shafts 240, the flatness of the material belt 300 can be maintained when taking material.

[0046] In one embodiment, both sides of the inner frame 200 are provided with blocking blocks 201, and both sides of the outer frame 100 are provided with locking components 120 driven by a cylinder 121 and capable of fastening the blocking blocks 201 to prevent the inner frame 200 from sliding. The locking component 120 includes a fastener 122, which includes a V-shaped action portion and a locking portion 1222 integrally formed at one end of the action portion, the locking portion 1222 extending toward the outer bend of the action portion, one end of the action portion away from the locking portion 1222 is hinged to the driving end of the cylinder 121, the middle part of which is hinged to one end of a connecting rod 123, the other end of the connecting rod 123 is hinged to the side of the cylinder 121 facing the outer frame 100, and the side wall of the outer frame 100 is provided with an opening 101 for the fastener 122 to move.

[0047] Among them, when the inner frame 200 slides into the outer frame 100, the cylinder 121 extends, driving the fastener 122 to rotate along the hinge point with the connecting rod 123, and the fastener 122 is buckled on the blocking block 201, that is, the locking part 1222 clamps the blocking block 201, thereby preventing the inner frame 200 from sliding out of the outer frame 100.

[0048] Working principle:

[0049] When material loading is required, the cylinder 121 contracts, driving the fastener 122 to release the blocking block 201, and the inner frame 200 is manually pulled out, and then the unloading pulley 211 that needs to be replaced is slid out along the inclined groove 2121 of the first mounting seat 212, and then the unloading pulley 211 with the material belt 300 is inserted into the first mounting seat 212 along the inclined groove 2121, and the material belt 300 is manually arranged, wherein the arrangement direction of the material belt 300 is the bottom of the first tension shaft 240, the top of another first tension shaft 240, the through groove 251 of the second tension shaft 250, the top of another group of first tension shafts 240, the bottom of another group of another first tension shaft 240, between the pressure wheel 222 and the first drive shaft 223, and the other second tension shaft 2 50's through slot 251 and material receiving pulley 231, and then push the inner frame 200 into the outer frame 100. After the locking assembly 120 fastens the blocking block 201, the fourth gear 111 of the motor 110 fixed on one side of the outer frame 100 just engages with the third gear 224 at one end of the first drive shaft 223. When the motor 110 rotates, the fourth gear 111 drives the third gear 224, that is, drives the first drive shaft 223. The first drive shaft 223 drives the second drive shaft 234 through the transmission belt. The second drive shaft 234 drives multiple second gears 235 thereon. The multiple second gears 235 respectively drive their corresponding first gears 233, that is, drive the material receiving pulley 231 to rotate, so that the material belt 300 moves along the above-mentioned direction.

[0050] Since the first driving shaft 223 and the second driving shaft 234 rotate simultaneously with the same power, the force on the material belt 300 can be evenly applied, thereby preventing the material belt 300 from breaking between the tension component 220 and the material receiving component 230 .

Since the present disclosure can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
