When the material receiving part and the material feeding part need to be replaced later, the strip A in the buffer area can be used for temporary feeding.

[0038] The first horizontal frame 100 is provided with a pressing connection component 600 for connecting the new and old strips A at the head end position, and the ends of the new and old strips A are melted and connected by the pressing connection component 600 to achieve the continuity of feeding.

The rotating outer ring 404 is connected to a guide driving component 400 for driving it to move along the surface of the first transmission roller 103 or the second transmission roller 104. Under the action of the guide driving component 400, the partition ring 403 slides along the surface of the first transmission roller 103 or the second transmission roller 104, thereby fine-tuning the spacing between the partition rings 403.

[0040] The first horizontal frame 100 is also provided with a pressing mechanism that matches the first transmission roller 103 and presses the upper surface of the strip A. The pressing mechanism makes the strip A close to the surface of the first transmission roller 103.

Both ends of the pressing beam 700 are connected to the upper end of the first horizontal frame 100 through a pressing vertical rod 701. A plurality of self-adjusting sleeves 705 are slidably provided on the pressing beam 700. A guide side plate 704 is horizontally provided on the outer side of the self-adjusting sleeve 705.

A plurality of auxiliary steel balls 702 distributed in an array are provided on the side of the clamping wheel 703 facing the separation ring 403. The auxiliary steel balls 702 are made of magnetic material so that the clamping wheel 703 and the separation ring 403 can be adsorbed. In this way, when the separation ring 403 slides, the clamping wheel 703 will also move with it. There is rolling friction between the auxiliary steel balls 702 and the separation ring 403, and no loss of components will be caused. The magnetic structure is also convenient for later maintenance.

The guide slide bars 406 are slidably sleeved on the guide slide bars 407, and the guide slide bars 406 are connected to a horizontal pushing member used to drive it to slide along the surface of the guide slide bars 407, and the guide slide bars 406 are driven to move on the horizontal seat through the horizontal pushing member, thereby driving the separation rings 403 to adjust the distance;

[0043] The horizontal pusher includes an outer plate arranged on the outer side of the guide slider 406, a telescopic screw sleeve 408 is fixedly provided on the outer plate, a push screw 409 is matched in the threaded hole of the telescopic screw sleeve 408, and the push screw 409 is connected to a push motor 410 for driving the push screw 409 to rotate, and the push motor 410 is fixedly installed on the horizontal seat. Under the drive of the push motor 410, the push screw 409 and the telescopic screw sleeve 408 rotate relative to each other, thereby driving the corresponding guide slider 406 to slide along the guide slide rod 407, so as to provide a horizontal thrust for the guide slider 406 to slide;

[0044] The connecting rod group includes a plurality of horizontally arranged connecting cross bars 801, which are connected to the guide partitioning component 401 on the first transmission roller 103. A plurality of connecting vertical sleeves 802 are also provided on the lower side of the connecting cross bars 801. A connecting vertical rod 803 is slidably provided at the lower end of the connecting vertical sleeve 802. The lower end of the connecting vertical rod 803 is connected to the guide partitioning component 401 on the second transmission roller 104. In this way, the guide partitioning components 401 on the first transmission roller 103 and the second transmission roller 104 can be moved synchronously, so as to realize the adjustment of the guide width at multiple positions, which greatly improves the efficiency of the adjustment.

[0045] The lifting pusher includes a lifting thread block 203 arranged on the outside of the first horizontal frame 100, and a lifting screw 202 is threaded on the lifting thread block 203. The lower end of the lifting screw 202 is connected to the lifting drive shaft 204, and the lifting drive shaft 204 is arranged at the output end of the lifting motor 205. The fixed end of the lifting motor 205 is installed on the second horizontal frame 102. The upper ends of the two lifting screws 202 are rotatably connected with the lifting beam 201. The lifting drive shaft 204 is driven to rotate by the lifting motor 205. The lifting drive shaft 204 drives the lifting screw 202 and the lifting thread block 203 to rotate relative to each other. Under the action of the thread, the first horizontal frame 100 moves up and down along the guide member, thereby providing power for the up and down movement of the second horizontal frame 102. The lifting motor 205 here is a synchronous motor:

[0046] The guide member includes a vertical guide rod 501 disposed at both ends of the first horizontal frame 100, and a vertical guide sleeve 500 is slidably sleeved at the lower end of the vertical guide rod 501, and the lower end of the vertical guide sleeve 500 is fixedly connected to the upper end of the second horizontal frame 102, so that the second horizontal frame 102 can be guided to float up and down to ensure the stability of the floating;

[0047] Working principle: In actual use, according to actual processing needs, the staff drives the guide slider 406 to move on the horizontal seat through the horizontal pusher, thereby driving the separation ring 403 to adjust the distance. A transmission width matching the width of the strip A will be formed between the multiple separation rings 403 to match the transmission needs of different strips A. The lifting drive shaft 204 is driven to rotate by the lifting motor 205, and the lifting drive shaft 204 drives the lifting screw 202 and the lifting thread block 203 to rotate relative to each other. Under the action of the thread, the first horizontal frame 100 moves up and down along the guide member, thereby providing power for the second horizontal frame 102 to move up and down, so that the multiple first horizontal frames on the upper side The height of the transmission roller 103 and the multiple second transmission rollers 104 on the lower side will change. When it is necessary to connect the new and old strips A, more strips A cannot be provided at this time. At this time, the second horizontal frame 102 is driven upward by the lifting pusher, so that the strips A buffered between the first transmission roller 103 and the second transmission roller 104 can be continuously provided to the end. In this way, there is no need to stop the machine for material receiving, which helps to improve processing efficiency. When the transmission width is adjusted, when the separating ring 403 slides, the clamping wheel 703 will also move together, and there is rolling friction between the auxiliary steel ball 702 and the separating ring 403, and no loss of components will be caused.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
