Description

Technical Field

[0001] This utility model relates to a feeding device for the production of glass fiber needled felt, belonging to the field of feeding technology for glass fiber needled felt. Background Technology

[0002] Glass fiber needle-punched felt is a filter material with a reasonable structure and good performance. It is made of glass fiber as raw material. The short-cut glass fiber felt after being combed is needle-punched with needles. The fibers are entangled between the glass fibers in the felt layer and between the glass fibers in the felt layer and the reinforcing glass fiber base cloth by mechanical means, so that the fiber web is reinforced and a felt-like non-woven filter material is made.

[0003] After the glass fiber needled mat is processed and produced, it needs to be rolled into rolls for packaging and transportation. In the actual production line, glass fiber needled mat is continuously produced. The glass fiber needled mat is rolled onto the material roller through the conveying mechanism. After the material roller finishes rolling a roll, it needs to be changed. The existing conveying mechanism is not convenient for handling the continuously produced glass fiber needled mat during the roller changing process.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a feeding device for the production of glass fiber needled felt. This device allows the continuously produced glass fiber needled felt to be stored after the material roll is fully wound, enabling uninterrupted production. The material is then released after the material roll is replaced.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A feeding device for producing glass fiber needled felt includes a support frame. An upper mounting frame is provided at an upper position and a lower mounting frame is provided at a lower position inside the support frame. The lower mounting frame can move up and down under the action of a driving unit.

[0008] The upper mounting frame is provided with a plurality of rotatable upper conveyor rollers, and the lower mounting frame is provided with a plurality of rotatable lower conveyor rollers;

[0009] The support frame has a feed inlet on the front and a discharge outlet on the rear. After entering through the feed inlet, the fiberglass needle-punched felt alternately passes over the upper and lower conveyor rollers and is discharged through the discharge outlet.

[0010] Furthermore, the lower mounting bracket is fixed to the bottom of the support frame by a support base. Both sides of the lower mounting bracket and the upper mounting bracket are vertically fixed with first sliding rods. The sides of the upper mounting bracket are respectively fixed with sliding seats, and the sliding seats of the upper mounting bracket are slidably mounted on the first sliding rods.

[0011] Furthermore, four upper conveying rollers are arranged on the upper mounting frame, and four lower conveying rollers are arranged on the lower mounting frame.

[0012] Furthermore, a front guide roller is provided on the inner side of the feed inlet of the support frame, and a rear guide roller is provided on the inner side of the discharge outlet of the support frame.

[0013] Furthermore, the drive assembly includes an active rotating shaft located on the front side of the support frame and driven by a drive motor, with a first active sprocket and a second active sprocket fixed on the active rotating shaft; a rear drive sprocket is rotatably mounted on the upper end of the upper mounting frame, and a front drive sprocket is rotatably mounted on the front side of the second active sprocket.

[0014] A first chain is wound around the rear drive sprocket and the first drive sprocket. One end of the first chain is connected to the rear end of the upper mounting frame, and the other end of the first chain is connected to the rear side of the counterweight. A second chain is wound around the second drive sprocket and the front drive sprocket. One end of the second chain is connected to the front end of the upper mounting frame, and the other end of the second chain is connected to the front side of the counterweight.

[0015] Furthermore, a second sliding rod is provided vertically at the front end of the support frame, and the counterweight is slidably mounted on the second sliding rod.

[0016] Furthermore, an upper clamping plate is fixed to the upper end of the outer side of the material outlet of the support frame, and a lower clamping plate is provided at the lower end of the outer side of the material outlet of the support frame. The lower clamping plate is driven by a cylinder.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] The support frame has an upper mounting frame located at the top and a lower mounting frame located at the bottom. The lower mounting frame can move up and down under the action of the drive unit. The upper mounting frame has multiple upper conveying rollers, and the lower mounting frame has multiple lower conveying rollers. When a roll of material is fully wound, the lower mounting frame moves from bottom to top under the action of the drive system, so that the continuously produced glass fiber needle-punched felt is stored between the upper and lower conveying rollers, which serves as a temporary storage function. This ensures that the production of material is not delayed when the roll is changed, and the material is temporarily stored first, and then released after the roll is changed.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0024] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, this utility model provides a feeding device for the production of glass fiber needled felt, including a support frame 1. The support frame 1 has an upper mounting frame 5 at the upper position and a lower mounting frame 6 at the lower position. The lower mounting frame 6 can move up and down under the action of the driving unit.

[0026] The upper mounting frame 5 is provided with a plurality of rotatable upper conveying rollers 7, and the lower mounting frame 6 is provided with a plurality of rotatable lower conveying rollers 8;

[0027] The support frame 1 has a feed inlet 2 on its front side and a discharge outlet 3 on its rear side. Fiberglass needle-punched felt enters through the feed inlet 2, alternately passes over the upper conveyor roller 7 and the lower conveyor roller 8, and exits through the discharge outlet 3. A material roll is located on one side of the support frame 1 near the discharge outlet 3. Once a material roll is full, it is replaced with the next roll to continue winding. When a material roll is full, the lower mounting frame 6 moves upwards under the action of the drive system, storing the continuously produced fiberglass needle-punched felt between the upper conveyor roller 7 and the lower conveyor roller 8. This serves as temporary storage, ensuring that material production is not delayed when the material roll 4 is replaced. The material is temporarily stored until the roll is replaced, at which point it is released.

[0028] The lower mounting bracket 6 is fixed to the bottom of the support frame 1 by a support base. Both sides of the lower mounting bracket 6 and the upper mounting bracket 5 are vertically fixed with first sliding rods 9. The upper mounting bracket 5 is fixed with sliding seats on both sides respectively. The sliding seats of the upper mounting bracket 5 are slidably mounted on the first sliding rods 9.

[0029] Preferably, four upper conveying rollers 7 are arranged on the upper mounting frame 5, and four lower conveying rollers 8 are arranged on the lower mounting frame 6.

[0030] A front guide roller 10 is provided on the inner side of the feed inlet 2 of the support frame 1, and a rear guide roller 11 is provided on the inner side of the discharge outlet 3 of the support frame 1. The front guide roller 10 and the rear guide roller 11 serve as guides.

[0031] The drive assembly includes an active rotating shaft located on the front side of the support frame 1 and driven by a drive motor 20. A first active sprocket 17 and a second active sprocket 18 are fixed on the active rotating shaft. A rear drive sprocket 16 is rotatably mounted on the upper end of the upper mounting bracket 5, and a front drive sprocket 19 is rotatably mounted on the front side of the second active sprocket 18.

[0032] A first chain 21 is wound around the rear drive sprocket 16 and the first drive sprocket 17. One end of the first chain 21 is connected to the rear end of the upper mounting frame 5, and the other end of the first chain 21 is connected to the rear side of the counterweight 14. A second chain 22 is wound around the second drive sprocket 18 and the front drive sprocket 19. One end of the second chain 22 is connected to the front end of the upper mounting frame 5, and the other end of the second chain 22 is connected to the front side of the counterweight 14.

[0033] The front end of the support frame 1 is provided with a second slide rod 15, and the counterweight 14 is slidably mounted on the second slide rod 15 to prevent the counterweight 14 from shaking.

[0034] When changing the material roll 4, the counterweight 14 pulls the first chain 21 and the second chain 22, thereby pulling the upper mounting frame 5 upward. The produced glass fiber needled felt is stored between the upper conveyor roller 7 and the lower conveyor roller 8. After changing the material roll, the drive motor 20 drives the first drive sprocket 17 and the second drive sprocket 18 to reverse, releasing the glass fiber needled felt between the upper conveyor roller 7 and the lower conveyor roller 8, thus achieving uninterrupted production.

[0035] An upper clamping plate 12 is fixed to the upper end of the outer side of the outlet 3 of the support frame 1, and a lower clamping plate 13 is provided at the lower end of the outer side of the outlet 3 of the support frame 1. The lower clamping plate 13 is driven by a cylinder. When the material roll 4 is replaced, the cylinder drives the lower clamping plate 13 to move upward, so that the glass fiber needle-punched felt is clamped and fixed between the upper clamping plate 12 and the lower clamping plate 13. After clamping, the upper mounting frame 5 moves upward for material storage.
