[0002] Felt is made of natural wool, using the felting properties of wool, and bonded through mechanical processing (without warp and weft interweaving). It is elastic and can be used as a material for shockproof, sealing, buffering and elastic wire needle cloth base felt. It has good adhesion and is not easy to loosen, and can be die-cut into parts of various shapes. It has good thermal insulation performance and can be used as a thermal insulation material. It has a dense structure and small pores, and can be used as a good filter material. It has good wear resistance and can be used as a polishing material. Among them, waterproof felt is a material with waterproof function, which is used in various fields. In the industry involving felt processing and manufacturing, the felt feeding process is an important link.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: an automatic feeding device for waterproof felt, comprising two side frames 1, an I-shaped frame 2 and four U-shaped frames 3, a second spring 15 is fixedly connected between the front and rear sides of the four U-shaped frames 3, the other end of the second spring 15 is fixedly connected to a mounting block 4, the left and right outer surfaces of the mounting block 4 are fixedly connected to side plates 5, the outer surfaces of the four upper side plates 5 facing away from each other are rotatably connected to connecting rods 6, the two left connecting rods 6 and the two right connecting rods 6 are rotatably connected to connecting blocks 7, the outer surfaces of the two connecting blocks 7 facing away from each other are fixedly connected to a first spring 14, the other end of the first spring 14 is fixedly connected to the outer surface of the I-shaped frame 2 Then, the top outer surfaces of the two connecting blocks 7 are fixedly connected with vertical rods 8. Specifically, the vertical rod 8 moves, and the vertical rod 8 pushes the connecting block 7, so that the connecting rod 6 rotates between the connecting block 7 and the side plate 5, and then the distance between the front and rear clamping plates 17 is close to each other, so that the middle end of the felt is in a loose state. When the first spring 14 and the second spring 15 are reset, the mounting block 4 drives the clamping plates 17 to reset the two ends of the felt, so that the felt generates a certain elastic vibration force when it is reset, which shakes off the dust particles on the felt, and by arranging an external vacuum cleaner on the left and right sides of the I-shaped frame 2, the dust particles under vibration are adsorbed by the external vacuum cleaner.

[0023] Two racks 9 are provided on the top outer surface of the I-shaped frame 2, and a cross plate 10 is fixedly connected to the top outer surface of the I-shaped frame 2. A first motor 11 is fixedly installed on the top outer surface of the cross plate 10, and two supporting shafts 12 are rotatably connected to the bottom outer surface of the cross plate 10. Half gears 13 are fixedly sleeved on the outer surfaces of the two supporting shafts 12, and the two half gears 13 are movably meshed with the outer surfaces of the two racks 9 respectively. Specifically, the first motor 11 is turned on, so that the two supporting shafts 12 drive the two half gears 13 to rotate respectively, and the two half gears 13 drive the racks 9 to move respectively, and the racks 9 drive the vertical rod 8 to move. When the first motor 11 drives the half gears 13 to rotate and the half gears 13 are disengaged from the surface of the rack 9, the first spring 14 and the second spring 15 are reset.

[0024] In this embodiment, the relative outer surfaces of the two upper mounting blocks 4 and the two lower mounting blocks 4 are all fixedly mounted with clamping cylinders 16, and the output ends of the clamping cylinders 16 are fixedly connected with clamping plates 17. Specifically, when the clamping cylinders 16 work, the clamping cylinders 16 drive the clamping plates 17 to clamp the felt.

[0025] In this embodiment, a first limiting rod is fixedly connected between the opposite outer surfaces on the front and rear sides of the U-shaped frame 3, the mounting block 4 is movably mounted on the outer surface of the first limiting rod, and the second spring 15 is mounted on the outer surface of the first limiting rod.

Specifically, the mounting block 4 slides on the outer surface of the first limiting rod when it moves, and the connecting block 7 slides on the outer surface of the second limiting rod when it moves. Under the action of the first limiting rod and the second limiting rod, the mounting block 4 and the connecting block 7 move stably in a straight line, and the second spring 15 and the first spring 14 are limited respectively by setting the first limiting rod and the second limiting rod to avoid the second spring 15 and the first spring 14 from tilting deformation.

[0026] In this embodiment, the output end of the first motor 11 and the outer surface of the rear support shaft 12 are both fixedly sleeved with a first transmission wheel 23, and a first belt 24 is wound around the two first transmission wheels 23. The output end of the first motor 11 and the outer surface of the front support shaft 12 are both fixedly sleeved with a second transmission wheel 25, and a second belt 26 is wound around the two second transmission wheels 25. Specifically, when the first motor 11 rotates, it drives the first transmission wheel 23 and the second transmission wheel 25 to rotate, and the two support shafts 12 rotate under the action of the first belt 24 and the second belt 26.

[0027] In this embodiment, electromagnetic slide rails 27 are fixedly installed between the opposite outer surfaces of the two side frames 1, and the output end of the electromagnetic slide rail 27 is fixedly connected to a connecting frame, and the other end of the connecting frame is fixedly connected to the outer surface of the I-shaped frame 2. The other ends of the side frame 1 and the electromagnetic slide rail 27 extend to the felt processing area. Specifically, after the felt is cleaned, the electromagnetic slide rail 27 is operated to transport the felt to the processing area for processing.

[0028] In this embodiment, the bottom outer surfaces of the two upper clamps 17 are fixedly connected with convex strips, and the top outer surfaces of the two lower clamps 17 are provided with grooves that match the convex strips. Specifically, the convex strips at the bottom of the upper clamp 17 are matched with the grooves at the top of the lower clamp 17. When the clamps 17 clamp the felt, the convex strips are inserted into the grooves, thereby improving the stability of the felt when clamping.

[0029] In this embodiment, two groups of vertical plates are fixedly connected to the top outer surface of the I-shaped frame 2, and the number of vertical plates in each group is two. A sliding rod is fixedly connected between the two vertical plates in each group. The outer surfaces of the two racks 9 are fixedly connected with slide plates, and the two slide plates are movably mounted on the outer surfaces of the two slide rods. Specifically, when the rack 9 moves, it drives the slide plate to slide on the outer surface of the slide rod, so that the rack 9 can move stably in a straight line.

[0030] In this embodiment, a slide groove is provided on the top outer surface of the I-shaped frame 2, and the two vertical rods 8 are slidably connected to the inside of the slide groove. Specifically, when the connecting block 7 moves, the vertical rod 8 slides inside the slide groove, and the slide groove provides a channel for the movement of the vertical rod 8.

[0031] In the specific implementation process, the clamping cylinder 16 drives the clamping plate 17 to clamp the two ends of the waterproof felt. After the clamping is completed, the first motor 11 is turned on. When the first motor 11 rotates, it drives the first transmission wheel 23 and the second transmission wheel 25 to rotate. Under the action of the first belt 24 and the second belt 26, the two support shafts 12 rotate, and the two support shafts 12 drive the two half gears 13 to rotate respectively. The two half gears 13 drive the rack 9 to move respectively. The rack 9 drives the slider 21 to move the vertical rod 8. The vertical rod 8 pushes the connecting block 7, so that the connecting rod 6 rotates between the connecting block 7 and the side plate 5, and then the distance between the front and rear clamping plates 17 is close to each other, so that the middle end of the felt is in a loose state. When the first motor 11 drives the half gears 13 to rotate, the two half gears 13 drive the rack 9 to move. When the wheel 13 rotates and the half gear 13 disengages from the surface of the rack 9, the first spring 14 and the second spring 15 reset, so that the mounting block 4 drives the clamping plate 17 to reset the two ends of the felt, so that the felt generates a certain elastic vibration force when resetting, and the dust particles on the felt are shaken off. As the first motor 11 rotates, the felt intermittently generates elastic vibration force to shake off the dust particles, and by arranging an external vacuum cleaner on the left and right sides of the I-shaped frame 2, the dust particles under vibration are adsorbed by the external vacuum cleaner, and then the electromagnetic slide rail 27 works to transport the felt to the processing area for processing, so that the dust particles on the felt can be cleaned before loading the felt, so as to avoid dust cleaning affecting subsequent processing and resulting in poor quality of the finished product.

[0032] Embodiment 2: Please refer to Figure 3 and Figure 8The present invention provides a technical solution: two connecting plates are fixedly connected to the top and bottom opposite outer surfaces of the I-shaped frame 2, a positive and negative screw rod 18 is rotatably connected between the two upper connecting plates, a second motor 20 is fixedly installed on the outer surface of the upper front connecting plate, the output end of the second motor 20 is fixedly connected to the positive and negative screw rod 18, the outer surface of the positive and negative screw rod 18 is threadedly connected to two threaded plates 19, a cross bar is fixedly connected between the opposite outer surfaces of the two lower connecting plates, two support plates are movably sleeved on the outer surfaces of the two cross bars, and four U-shaped frames 3 are respectively fixed on the bottom outer surfaces of the two threaded plates 19 and the top outer surfaces of the two support plates.

[0033] During the specific implementation process, when feeding felts of different sizes, the second motor 20 drives the forward and reverse screws 18 to rotate, and the forward and reverse screws 18 drive the threaded plate 19 to move. By adjusting the positions of the front and rear clamping plates 17, the front and rear clamping plates 17 are respectively located at the two ends of the felt, thereby clamping and conveying the two ends of the felts of different sizes.

[0034] Embodiment 3: Please refer to Fig. 9 The present invention provides a technical solution: the bottoms of the two racks 9 are hollow, the front and rear inner walls of the two racks 9 are fixedly connected with iron bars, the top outer surfaces of the two vertical rods 8 are fixedly connected with side rods, the top outer surfaces of the side rods are fixedly connected with sliders 21, and the front and rear outer surfaces of the sliders 21 are fixedly installed with powerful electromagnets 22, which are movably fitted with the outer surfaces of the iron bars.

[0035] During the specific implementation process, when the second motor 20 is working, the powerful electromagnet 22 stops being energized, and the powerful electromagnet 22 stops adsorbing the iron bar inside the rack 9, so that the slider 21 and the rack 9 can move relative to each other. When the position of the threaded plate 19 is adjusted, the angle between the connecting rods 6 will change, causing the vertical rod 8 to move. At this time, the vertical rod 8 drives the slider 21 to slide inside the rack 9. When the adjustment is completed, the powerful electromagnet 22 is energized, and the powerful electromagnet 22 is adsorbed with the iron bar inside the rack 9, so that when the rack 9 moves, it can drive the slider 21 to move the vertical rod 8.

[0036] Working principle: When the present invention is in use, the waterproof felt is transported, and the clamping cylinder 16 drives the clamping plate 17 to clamp the two ends of the waterproof felt. After clamping, the first motor 11 is turned on. When the first motor 11 rotates, it drives the first transmission wheel 23 and the second transmission wheel 25 to rotate. Under the action of the first belt 24 and the second belt 26, the two support shafts 12 rotate, and the two support shafts 12 drive the two half gears 13 to rotate respectively. The two half gears 13 drive the rack 9 to move respectively. The rack 9 drives the slider 21 to move the vertical rod 8. The vertical rod 8 pushes the connecting block 7, so that the connecting rod 6 rotates between the connecting block 7 and the side plate 5, and then the distance between the front and rear clamping plates 17 is close to each other, so that the middle end of the felt is In a loose state, when the first motor 11 drives the half gear 13 to rotate and the half gear 13 disengages from the surface of the rack 9, the first spring 14 and the second spring 15 reset, so that the mounting block 4 drives the clamping plate 17 to reset the two ends of the felt, so that the felt generates a certain elastic vibration force when resetting, and shakes off the dust particles on the felt. As the first motor 11 rotates, the felt intermittently generates elastic vibration force to shake off the dust particles, and the dust particles under vibration are adsorbed by an external vacuum cleaner, and then the electromagnetic slide rail 27 works to transport the felt to the processing area for processing, so that the dust particles on the felt can be cleaned before loading, so as to avoid dust cleaning affecting subsequent processing and resulting in poor quality of the finished product.

[0037] When feeding felts of different sizes, the second motor 20 drives the forward and reverse screws 18 to rotate, and the forward and reverse screws 18 drive the threaded plate 19 to move. By adjusting the positions of the front and rear clamping plates 17, the front and rear clamping plates 17 are respectively located at the two ends of the felt, thereby clamping and conveying the two ends of the felts of different sizes.

[0038] When the second motor 20 is working, the powerful electromagnet 22 stops being energized, and the powerful electromagnet 22 stops adsorbing the iron bar inside the rack 9, so that the slider 21 and the rack 9 can move relative to each other. When the position of the threaded plate 19 is adjusted, the angle between the connecting rods 6 will change, causing the vertical rod 8 to move. At this time, the vertical rod 8 drives the slider 21 to slide inside the rack 9. When the adjustment is completed, the powerful electromagnet 22 is energized, and the powerful electromagnet 22 is adsorbed with the iron bar inside the rack 9, so that when the rack 9 moves, it can drive the slider 21 to move the vertical rod 8.
