Among them, the lifting frame 27 is connected to the base 313 of the feeding module 30.

[0048] like Figure 1 , Figure 3 and Figure 8As shown, the material feeding module 30 includes a material return assembly 31 and a conveying assembly 32, wherein the material return assembly 31 is movably arranged on the lifting module 20 and moves with the lifting module 20, and at least a part of the material return assembly 31 can move in a direction close to or away from the feeding module 10; the conveying assembly 32 is movably arranged on the material return assembly 31, the conveying assembly 32 is located downstream of the feeding module 10 and upstream of the material return assembly 31, and at least a part of the conveying assembly 32 can move in a direction perpendicular to the conveying direction of the material feeding module 30.

[0049] like Figures 3 to 5 As shown, the feed module 30 further includes a deflection correction component 33, at least a part of which is movably arranged on the unloading component 31, the deflection correction component 33 is drivingly connected to the conveying component 32 and can drive at least a part of the conveying component 32 to move in a direction perpendicular to the conveying direction of the feed module 30, and the deflection correction component 33 is located on a side of the conveying component 32 away from the stitching module 40. In this way, the deflection correction component 33 is arranged on a side of the conveying component 32 away from the rubber material to prevent the deflection correction component 33 from interfering with the rubber material, and the deflection correction component 33 drives the conveying component 32 to move in the width direction of the rubber material to achieve the deflection correction purpose.

[0050] like Figures 3 to 5 As shown, the deviation correction component 33 includes a first mounting frame 331 and a first driving part 332, wherein at least a part of the first mounting frame 331 is movably arranged on the material stripping component 31, and one end of the conveying component 32 close to the material stripping component 31 is arranged on the first mounting frame 331 and moves with the first mounting frame 331; the first driving part 332 is drivingly connected to the first mounting frame 331 and drives the first mounting frame 331 to move in a direction perpendicular to the conveying direction of the material feeding module 30.

[0051] It should be noted that, in this embodiment, a plurality of second sliders 3311 are provided on the first mounting frame 331, and a plurality of slide rails are provided on the second mounting frame 314. The plurality of second sliders 3311 correspond one-to-one to the plurality of slide rails and slide in cooperation with each other, so that the first mounting frame 331 can move in a direction perpendicular to the conveying direction of the feeding module 30.

[0052] It should be noted that, in the present embodiment, the deviation correction component 33 also includes a first lead screw 333 and a nut 334, wherein the first driving portion 332 is drivingly connected to the first lead screw 333 and can drive the first lead screw 333 to rotate, the nut 334 is sleeved on the first lead screw 333, and the nut 334 is connected to the first mounting bracket 331, so that the nut 334 can drive the first mounting bracket 331 to move along the first lead screw 333, so as to adjust the position of the material head 12 to achieve the purpose of deviation correction.

[0053] like Figure 1 and Figure 7 As shown, the automatic feeding device further includes a first detection component 50 and at least two first sensing components 60, wherein the first detection component 50 is arranged on the side of the stitching module 40 close to the transmission component 32, and the first detection component 50 is connected to the first driving part 332 by signal; the two first sensing components 60 are respectively matched with the first detection component 50, and at least one first sensing component 60 is respectively arranged at one end of the transmission component 32 and the material stripping component 31 close to each other. In this way, the first detection component 50 respectively detects the edge position of the material tail located at the material stripping component 31 and the edge position of the material head 12 located at the transmission component 32. If there is a deviation between the edge position of the material tail and the edge position of the material head 12, the first driving part 332 is controlled to drive the transmission component 32 to move along the width direction of the rubber material to ensure that the material head 12 is aligned with the material tail.

[0054] like Figure 3 As shown, a first sensing component 60 is respectively disposed at one end of the conveying component 32 and the material stripping component 31 close to each other, and the two first sensing components 60 are disposed opposite to each other, and the two first sensing components 60 are respectively disposed at one end of the width direction of the conveying component 32 and the material stripping component 31. In this way, the first sensing component 60 located in the conveying component 32 is used to detect the position of one side of the material head 12 in the width direction, and the first sensing component 60 located in the material stripping component 31 is used to detect the position of a corresponding side of the material tail in the width direction, so as to improve the detection efficiency.

[0055] like Figure 3As shown, the first sensing component 60 includes a first reflector 61, and the first detection component 50 includes a first control unit, a first electric eye 51, a second electric eye 52 and a second driving unit 53, wherein the first control unit is signal-connected to the first driving unit 332; the first electric eye 51 is arranged corresponding to the first reflector 61 on the transmission component 32 and can receive the light signal reflected by the first reflector 61 on the transmission component 32; the second electric eye 52 is arranged corresponding to the first reflector 61 on the material return component 31 and can receive the light signal reflected by the first reflector 61 on the material return component 31, and the first electric eye 51 and the second electric eye 52 are respectively signal-connected to the first control unit; the second driving unit 53 is respectively drive-connected to the first electric eye 51 and the second electric eye 52, and drives the first electric eye 51 and the second electric eye 52 to move in a direction perpendicular to the conveying direction of the feeding module 30. In this way, the first electric eye 51 corresponds to the first reflector 61 on the conveying component 32, and is used to detect the side position of the material head 12. The second electric eye 52 corresponds to the first reflector 61 on the material return component 31, and is used to detect the side position of the material tail. When there is a deviation between the side position of the material head 12 and the side position of the material tail, the first control unit controls the movement of the first drive unit 332 to correct the deviation. When another specification of rubber is replaced, the width of the rubber changes. The second drive unit 53 drives the first electric eye 51 and the second electric eye 52 to move in a direction perpendicular to the conveying direction of the feeding module 30 to ensure that the signals emitted by the first electric eye 51 and the second electric eye 52 can illuminate the edge position in the width direction of the rubber, so as to accurately detect the edge position of the material head 12 and the edge position of the material tail.

[0056] It should be noted that, in the present embodiment, the first detection component 50 also includes an electric eye mounting seat 54, a third slider 55, a second lead screw 56 and a connecting seat 57, wherein the second driving unit 53 and the second lead screw 56 are respectively arranged on the connecting seat 57, the second driving unit 53 is drivingly connected to the second lead screw 56 and can drive the second lead screw 56 to rotate, the electric eye mounting seat 54 is sleeved on the second lead screw 56 and can move along the second lead screw 56, the first electric eye 51 and the second electric eye 52 are respectively arranged on the electric eye mounting seat 54, and the electric eye mounting seat 54 drives the first electric eye 51 and the second electric eye 52 to move in a direction perpendicular to the conveying direction of the feeding module 30, so that when another rubber material is replaced, the width of the rubber material changes, and the positions of the first electric eye 51 and the second electric eye 52 are adjusted to ensure that the signals emitted by the first electric eye 51 and the second electric eye 52 can cover the side positions in the width direction of the rubber material.

[0057] It should be noted that, in this embodiment, the area of ​​the square signal emitted by the first electric eye 51 is smaller than the area of ​​the direction area of ​​the first reflector 61 of the transmission component 32, and the area of ​​the square signal emitted by the second electric eye 52 is smaller than the area of ​​the direction area of ​​the first reflector 61 of the return component 31.

[0058] like Figure 3 As shown, the conveying assembly 32 has a first conveying section 321, the material stripping assembly 31 has a second conveying section 311, at least a portion of the material head 12 of one of the two overlapping rubber materials is located on the first conveying section 321, and at least a portion of the material tail of the other rubber material is located on the second conveying section 311, the material stripping assembly 31 also has an overlapping portion 312, the overlapping portion 312 is arranged between the first conveying section 321 and the second conveying section 311, and the stitching module 40 is located above the overlapping portion 312 and can move in a direction close to or away from the overlapping portion 312. In this way, the stitching module 40 overlaps the material head 12 of the first conveying section 321 and the material tail of the second conveying section 311 at the overlapping portion 312.

[0059] like Figure 3 As shown, the first conveying section 321 and the second conveying section 311 have the same height, and the height of the overlapping portion 312 is less than the height of the first conveying section 321. In this way, the rubber material passes through the first conveying section 321 and the second conveying section 311 in sequence. The equal height of the first conveying section 321 and the second conveying section 311 is conducive to the conveying of the rubber material. The height of the overlapping portion 312 is less than the height of the first conveying section 321. When the material stripping component 31 moves toward the conveying component 32, the overlapping portion 312 is used to avoid the second conveying section 311 from moving toward the first conveying section 321. At this time, the second conveying section 311 is partially located above the overlapping portion 312, and the material head 12 and the material tail are overlapped at the part of the second conveying section 311 located above the overlapping portion 312.

[0063] Preferably, the fourth driving part 315 and the fifth driving part 316 are both cylinders.

[0064] It should be noted that, in this embodiment, the second mounting frame 314 includes a first slider 3141 , and the second mounting frame 314 is slidably connected to the slide rail on the base 313 via the first slider 3141 , so that the second mounting frame 314 can move in a direction close to or away from the feeding module 10 .

[0065] It should be noted that, in this embodiment, the material stripping assembly 31 further includes a connecting frame 318 and a material blocking plate 319, wherein the driving end of the fifth driving unit 316 is connected to the material stripping plate 317 through the connecting frame 318, thereby driving the material stripping plate 317 to move in a direction close to or away from the conveying assembly 32. The material stripping plate 317 is provided with two strip holes, which extend in a direction perpendicular to the conveying direction of the feeding module 30, and the two material blocking plates 319 are correspondingly arranged in the two strip holes. The two material blocking plates 319 are located at both ends of the width direction of the rubber material during the movement of the rubber material, and the distance between the two material blocking plates 319 can be adjusted through the strip holes according to different types of rubber materials, so as to ensure that the two material blocking plates 319 are always located at both ends of the width direction of the rubber material and play a role in guiding and limiting the movement of the rubber material.

[0066] like Figure 6 As shown, the stitching module 40 includes a third mounting frame 41, a sixth driving unit 42, a seventh driving unit 43, a joint pressing plate 44 and a positioning baffle 45, wherein the sixth driving unit 42 and the seventh driving unit 43 are respectively arranged on the third mounting frame 41; the sixth driving unit 42 is drivingly connected to the joint pressing plate 44 and drives the joint pressing plate 44 to move in a direction close to or away from the conveying assembly 32; the seventh driving unit 43 is drivingly connected to the positioning baffle 45 and drives the positioning baffle 45 to move in a direction close to or away from the material stripping assembly 31. In this way, the seventh driving unit 43 drives the positioning baffle 45 to move in a direction close to the conveying assembly 32, the positioning baffle 45 fixes the material tail and stops the material head 12 from moving, the sixth driving unit 42 drives the joint pressing plate 44 to move in a direction close to the conveying assembly 32, and the joint pressing plate 44 presses the material head 12 on the material tail to achieve overlapping.

[0067] like Figure 6 As shown, the joint pressing plate 44 and the positioning baffle 45 are parallel to each other and arranged at intervals along the conveying direction of the feeding module 30. In this way, the joint pressing plate 44 and the positioning baffle 45 can move toward the stitching module 40 respectively to prevent mutual interference.

[0068] It should be noted that, in this embodiment, the automatic feeding device further includes a conveying module 80 , which is disposed at one end of the sewing module away from the feeding module 30 , and the adhesive on the feeding module 10 is transferred to the conveying module 80 .

[0069] like Figure 6As shown, the stitching module 40 further includes a second detection member 46, and the automatic feeding device further includes a second sensing member 70 that cooperates with the second detection member 46, and the second sensing member 70 is disposed on the overlap portion 312. In this way, when the tail of the material passes between the second sensing member 70 and the second detection member 46, the conveying module 80 is controlled to stop moving, and the tail of the material stops moving. When the material head 12 passes between the second sensing member 70 and the second detection member 46, the rubber material of the feeding module 10 is controlled to stop being guided away, and the material head stops moving.

[0070] Preferably, the second sensing element 70 is a second reflector, and the second detecting element 46 is a photoelectric switch.

[0071] It should be noted that, in the present embodiment, the sewing module 40 further includes a brush roller assembly 47 and a material-blocking roller assembly 48, wherein the brush roller assembly 47 and the material-blocking roller assembly 48 are both arranged on the third mounting frame 41, and the brush roller assembly 47 is located between the joint pressure plate 44 and the material-blocking roller assembly 48. The rubber material passes through the brush roller assembly 47 and the material-blocking roller assembly 48 in turn and moves to the conveying module 80, and the brush roller assembly 47 can prevent the tail of the material from curling up.

[0072] The automatic feeding device in this embodiment includes a deviation correction process and an overlap process, wherein the deviation correction process is as follows:

[0073] When the conveying module 80 is about to run out of material, the conveying speed of the conveying module 80 is reduced, and the curtain moves forward slowly. The feed module 30 rises upward under the action of the lifting module 20. When the second detection member 46 detects that the tail of the material has passed the second sensing member 70, the conveying module 80 stops moving, so that the edge of the tail of the material is in the square area of ​​the first reflector 61 on the material return assembly 31. The fourth driving unit 315 drives the base 313, the fifth driving unit 316, the material return plate 317, the connecting frame 318, the material stopper 319, the overlapped part 312, the conveying assembly 32 and the deviation correction assembly 33 to move together in the direction close to the feeding module 10. The first conveying section 321 of the conveying assembly 32 moves to the lower part of the feeding end of the feeding module 10. At this time, the third driving unit 322 drives the synchronous belt 325 to rotate, and the guide mechanism of the feeding module 10 drives the material head 12 to move downward. When the material head 12 contacts the synchronous belt 325, it is transported to the direction of the tail of the material through the synchronous belt 325. When the second detection member 46 detects that the material head 12 reaches the second sensing member 70, the deflection mechanism and the third driving unit 322 of the feeding module 10 stop, the material head 12 stops moving and the material roll is rewound, so that the edge of the material head 12 is in the square area of ​​the first reflective plate 61 on the conveying component 32. At this time, the first electric eye 51 detects the edge position quantity dist1 of the material head 12, and the second electric eye 52 detects the edge position quantity dist2 of the material tail. The first control unit controls the movement of the correction component 33 according to the two position quantities, the first driving unit 332 drives the first screw 333 to rotate, and the nut 334 drives the first conveying section 321 to move and adjust along the width direction of the rubber material, so that the edges of the material head 12 and the material tail are aligned to achieve the correction purpose.

[0074] After the deviation correction process, the overlapping process is carried out. The overlapping process is as follows:

[0075] The fifth driving part 316 drives the material stripping plate 317 to move toward the material head 12 side through the connecting frame 318, and a part of the material stripping plate 317 moves to the top of the overlapping part 312, and the seventh driving part 43 drives the positioning baffle 45 to move downward. At this time, the material tail is below the positioning baffle 45, and the end of the material tail extends about 5 mm toward the material head 12 side relative to the positioning baffle 45. The third driving unit 322 drives the material head 12 on the synchronous belt 325 to transport toward the side of the material tail. When the material head 12 touches the positioning baffle 45, the material head 12 and the material tail partially overlap, and the material head 12 is located above the material tail. The sixth driving unit 42 drives the joint pressure plate 44 to move downward to overlap the material head 12 and the material tail together. After the overlapping is completed, the positioning baffle 45 and the joint pressure plate 44 return upward. The fourth driving unit 315 drives the base 313, the conveying assembly 32 and the correction assembly 33 to move back in the direction away from the feeding module 10. The feeding module 30 descends under the action of the lifting module 20, and the feeding is completed.

[0076] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the feeding module 30 in this scheme is lifted and moved to a specific position by the lifting module 20, so that one end of the feeding module 30 is located below the feeding end of the feeding module 10, so as to facilitate the access to the material head 12 of the rubber material of the feeding module 10, at least a part of the feeding module 30 can move relative to the lifting module 20 in a direction close to the feeding module 10 to move the material tail to the overlapping position, at least another part of the feeding module 30 can move in a direction perpendicular to the conveying direction of the feeding module 30, that is, move along the width direction of the rubber material to align the edges of the material head 12 and the material tail in the width direction, and at least a part of the stitching module 40 can move in a direction close to the feeding module 30 to overlap the material head 12 of one rubber material and the material tail of another rubber material located on the feeding module 30. The material head 12 and the material tail are overlapped under the action of the sewing module 40. The material head 12 before material refilling does not need to be placed in a fixed position, which can achieve the purpose of automatic material refilling. The automatic material refilling device has better performance, saves production costs, and is conducive to promotion and use.
