Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, an embodiment of this application discloses a roll feeding buffer machine, including a mounting plate 1, a feeding roll 2 is disposed on the mounting plate 1, a buffer mechanism is disposed on one side of the feeding roll 2, a stripping mechanism is disposed on the side of the buffer mechanism away from the feeding roll 2, and a receiving platform 3 disposed between the feeding roll 2 and the buffer mechanism.

[0024] The buffer mechanism includes a guide wheel assembly mounted on the mounting plate 1. The guide wheel assembly includes multiple guide wheels and a buffer wheel assembly disposed between the multiple guide wheels and capable of horizontal movement in the direction of the guide wheels.

[0025] Specifically, during operation, the roll material is transported to the feeding roll 2 by an external forklift. A feeding roll 2 drive motor is installed on one side to drive the feeding roll 2 to rotate. The feeding roll 2 conveys the roll material forward. The roll material passes through the tape receiving platform 3 and the buffer mechanism in one go. Under the action of the peeling mechanism, the protective mold is peeled off, and the PET film behind the glass protective film is transported to the subsequent coating mechanism. When the roll conveyor is close to the end and a new roll material needs to be connected, the tape receiving platform 3 presses the roll material. The operator manually feeds the new roll material and attaches the front end of the new roll material to the tail end of the old roll material. During the manual feeding process, the feeding operation cannot be performed at the feeding point. At this time, the buffer wheel assembly moves horizontally towards the guide wheel to release the buffered material tape, so that the coating operation can continue. After the new roll material at the front end is fed, the feeding roll 2 continues to feed. At this time, the buffer wheel assembly moves horizontally away from the guide wheel to perform the buffering operation of the material tape again.

[0026] The buffer mechanism in this structure allows the material buffered at the buffer mechanism to continue to be conveyed forward when the front-end roll is being replaced with a new roll. This means that the machine can continue to perform subsequent coating, drying and other operations without stopping the machine during the material replacement operation.

[0027] In this embodiment, the guide wheel assembly includes a first guide wheel 4 and a second guide wheel 5 arranged horizontally. A third guide wheel 6 and a fourth guide wheel 7 are arranged sequentially below the second guide wheel 5. The buffer wheel assembly includes a first buffer wheel 8 and a second buffer wheel 9, which are located below the first guide wheel 4. It also includes a buffer wheel drive plate 10, on which the first buffer wheel 8 and the second buffer wheel 9 are arranged. The second buffer wheel 9 is located below the first buffer wheel 8. A buffer drive cylinder 11 is provided on the mounting plate 1 to drive the buffer wheel drive plate 10 to move horizontally.

[0028] Specifically, during operation, the material belt sequentially passes around the first guide wheel 4, the second guide wheel 5, the first buffer wheel 8, the third guide wheel 6, the second buffer wheel 9, and the fourth guide wheel 7. When in buffer state, the first buffer wheel 8 and the second buffer wheel 9 are located far away from the third guide wheel 6 and the fourth guide wheel 7. At this time, the first buffer wheel 8 and the second buffer wheel 9 are farther away from the third guide wheel 6 and the fourth guide wheel 7, so they can pass around a longer material belt. When it is necessary to release the buffered material belt, the buffer drive cylinder 11 drives the buffer wheel drive plate 10 to move towards the third guide wheel 6 and the fourth guide wheel 7, so as to slowly release the material belt.

[0029] The buffer mechanism in this structure is simple; it only requires driving the buffer wheel to move to realize the storage and release operations.

[0030] In this embodiment, the third guide wheel 6, the first buffer wheel 8, the fourth guide wheel 7, and the second buffer wheel 9 are staggered in height.

[0031] In this structure, by staggering the third guide wheel 6, the first buffer wheel 8, the fourth guide wheel 7, and the second buffer wheel 9, the number of mixed layers of the material strip can be increased, thereby increasing the amount of mixed material strip.

[0032] In this embodiment, the receiving platform 3 includes a support plate 31, a positioning cutting slit 32 is provided in the middle of the support plate 31, a detachable waste box 33 is provided at the bottom of the support platform located at the positioning cutting slit 32, a first pressing block 34 and a second pressing block 35 are respectively provided at both ends of the support plate 31 along the product movement direction, and also includes a first pressing drive cylinder 36 for driving the first pressing block 34 to move toward the support plate 31 and a second pressing drive cylinder 37 for driving the second pressing block 35 to move toward the support plate 31.

[0033] Specifically, when the coil feeder approaches the end and a new coil needs to be connected, the first pressing drive cylinder 36 and the second pressing drive cylinder 37 drive the first pressing block 34 and the second pressing block 35 to move and press the tail material. The operator manually feeds the new coil. At the same time, the operator cuts the tail end of the old coil with a blade along the positioning cutting gap 32 so that the tail end of the old coil is flush. At this time, the first pressing block 34 is released, the waste material is removed, and the front end of the new coil is glued to the tail end of the old coil. After the connection is completed, the second pressing block 35 is released and the feeding operation continues.

[0034] In this structure, the tail material can be pressed by the receiving platform 3, which facilitates the receiving operation. At the same time, the positioning cutting gap 32 can facilitate the cutting of the tail material, thereby ensuring the flatness of the tail material. Meanwhile, the detachable waste box 33 can collect the debris during cutting and prevent the debris from scattering everywhere.

[0035] In this structure, a first traction wheel 12 is provided between the receiving platform 3 and the buffer mechanism, and a second traction wheel 13 is provided between the buffer mechanism and the stripping mechanism. A first abutting wheel 14 and a first abutting drive mechanism 15 that drives the first abutting wheel 14 to move in the direction of the first traction wheel 12 are provided on one side of the first traction wheel 12. A second abutting wheel 16 and a second abutting drive mechanism 17 that drives the second abutting wheel 16 to move in the direction of the second traction wheel 13 are provided on one side of the second traction wheel 13.

[0036] Specifically, at the beginning of the operation, the operator will pass the material belt sequentially between the first traction wheel 12 and the first abutment wheel 14, and between the second traction wheel 13 and the second abutment wheel 16. Then, the first abutment wheel 14 moves towards the first traction wheel 12, and the second abutment wheel 16 moves towards the second traction wheel 13, so that the material belt is in close contact with the first traction wheel 12 and the second traction wheel 13. Thus, under the active drive of the first traction wheel 12 and the second traction wheel 13, the material belt can be actively transported forward.

[0037] In this structure, the first abutting wheel 14 and the second abutting wheel 16 make it easy to thread the material belt, and at the same time make the threaded material belt fit tightly against the first traction wheel 12 or the second traction wheel 13, thereby enabling better conveying of the material belt.

[0038] In this embodiment, the stripping mechanism includes a waste roll 18, one end of which is provided with a waste roll drive motor 19 for driving the waste roll 18 to rotate, a material conveying guide shaft 20 is provided below the waste roll 18, and a stripping roller 21 is also provided at the front end of the waste roll 18 and the material conveying guide shaft 20. A third abutting wheel 22 and a third abutting drive mechanism 23 for driving the third abutting wheel 22 to move toward the stripping roller 21 are provided on one side of the stripping roller 21.

[0039] During the peeling operation, in the preparation work, the material strip passes between the peeling roller 21 and the third abutment roller 22. The operator first peels the front section and sticks the peeled protective film end to the waste roll. The peeled PET film is pulled to the feeding guide shaft 20 and wound around the winding mechanism at the end. During the peeling operation, under the active rotation of the waste roll 18, the protective film is torn off and wound around the waste roll 18. The PET film continues to be transported forward for subsequent coating, drying and winding operations.

[0040] In this embodiment, an antistatic bar 24 is provided between the stripping roller 21 and the receiving roller.

[0041] In this structure, the antistatic bar 24 is used to remove static electricity from the PET film after the protective film is removed, thereby ensuring the quality of the subsequent roughing slurry.

[0042] In this embodiment, a first tension roller 25 is provided between the feeding roll 2 and the buffer mechanism, and a second tension roller 26 is provided between the stripping roller 21 and the waste roll 18.

[0043] In this structure, the first tension roller 25 and the second tension roller 26 can detect the tension of the conveying belt, so that each drive shaft can be adjusted in time, thereby ensuring that the conveying belt is in a taut state during transportation, and thus ensuring the accuracy of the subsequent coating material.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
