Description

Technical Field

[0001] The utility model belongs to the technical field of plastic woven bag recycling, in particular to a melting device for recycling plastic woven bags. Background Art

[0002] Plastic woven bag recycling mainly refers to waste recycling. Waste is divided into two parts. One is unused, which is produced during the production process of woven bags, such as cutting, or defective products that do not meet quality standards. The other is woven bags that have been cleaned after use. Before recycling, these two types of waste need to be crushed into plastic fragments or strips, and then melted into liquid raw materials through high-temperature melting, and reused.

[0003] For the method of melting plastic woven bags, a high-temperature furnace is mostly used. The crushed waste is placed in the furnace and then heated to melt. For example, patent application No. 202322387192.3 discloses a waste recycling device for the production of plastic woven bags, including a recycling furnace, a connecting vertical plate and a recycling barrel, etc. An appropriate amount of woven bags to be recycled is placed in the recycling barrel, and then the woven bag plastic in the center of the recycling barrel can be melted by the recycling furnace. After melting, the lifting handle can be pulled up to make the L-shaped vertical plate slide out of the lifting slide, thereby facilitating the removal of the recycling barrel and the material in the center of the recycling barrel, which is convenient for the subsequent production of woven bags.

[0004] The existing plastic woven bag waste is piled up together in the melting equipment. When the temperature rises, the waste inside is heated more slowly and takes longer to melt than the waste outside. Therefore, the waste is gradually melted from the outside to the inside, which results in uneven heating and a longer time required for the overall melting of the waste. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a melting device for recycling plastic woven bags. By moving the waste out and the waste sliding, the fallen waste can be spread on the filter. Compared with the original phenomenon of stacking together, the waste on the filter has a uniform heating effect. Compared with the original phenomenon of uneven heating of the waste, the evenly heated waste can be melted synchronously, thereby reducing the time required for the overall melting of the waste.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A melting device for recycling plastic woven bags, comprising a bottom plate, a mounting plate fixedly connected to the left side of the top of the bottom plate, a material box fixedly connected to the upper right side of the mounting plate, an opening provided on the top of the material box, a slope provided on the left side of the bottom of the material box, a plurality of notches provided on the right side of the bottom of the material box, a fixing plate located below the material box fixedly connected to the right side of the mounting plate, a motor 1 fixedly connected to the front side of the fixing plate, a rotating rod located at the rear side of the fixing plate fixedly connected to the output shaft of the motor 1, a plurality of shifting rods fixedly connected to the side of the rotating rod, the number of the shifting rods being the same as the number of the notches and corresponding to each other A support plate is fixedly connected to the right side of the top of the bottom plate, and a heating box is rotatably connected to the top of the support plate. An opening is provided on the left side of the top of the heating box below the material box. An electric heating pipe is fixedly connected to the right side of the top of the inner cavity of the heating box, and a filter screen is fixedly connected to the right side of the bottom of the heating box below the electric heating pipe. A connecting plate located at the lower left side of the bottom of the heating box is fixedly connected to the top of the bottom plate, a rotating shaft is rotatably connected to the connecting plate, a cam is fixedly sleeved on the left end of the rotating shaft, and a motor 2 is fixedly connected to the right side of the connecting plate, and the output shaft of the motor 2 is fixedly connected to the right end of the rotating shaft.

[0008] Furthermore, a support column is fixedly connected to the top of the bottom plate, and the support column is located below the left side of the bottom of the heating box. A rubber pad is fixedly connected to the top of the support column.

[0009] Furthermore, a limit plate is fixedly connected to the right side of the mounting plate, and the limit plate is located between the fixing plate and the heating box.

[0010] Furthermore, a collecting hood located at the filter screen is fixedly connected to the bottom of the heating box, and a discharge pipe is connected to the bottom of the collecting hood.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The motor 1 drives the lever to repeatedly push the waste in the material box out of the slot, so that the waste in the material box will not be discharged directly, but in an orderly manner. The motor 2 drives the cam to repeatedly lift and tilt the heating box, so that the waste can slide in the heating box in an orderly manner, so that the falling waste can be spread on the filter. Compared with the original phenomenon of piling together, when the waste is subsequently heated by the electric heating tube, the heating effect of the waste on the filter is consistent. Compared with the original phenomenon of uneven heating of the waste, the evenly heated waste can be melted synchronously, thereby reducing the time required for the overall melting of the waste.

[0013] 2. The support column is used to support the left side of the heating box so that the heating box can be in a horizontal state after tilting, avoiding the left side of the heating box from tilting downward. As a result, the left side of the heating box can only tilt upward, which is convenient for the waste to slide to the right in the heating box onto the filter. The rubber pad is used to reduce the impact generated when the support column contacts the heating box. The limit plate limits the upward tilt of the heating box to avoid the heating box from being too upward and colliding with the rotating lever. The collection cover and the discharge pipe are used to collect the melted plastic raw materials on the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Working principle: In the utility model, the shredded plastic woven bag waste is put into the material box 3. It should be noted that the waste does not need to be pulverized into particles, but only needs to be pulverized into fragments or strips. In this way, after the waste falls to the bottom of the material box 3, it cannot rely on its own weight in the expanded state and falls directly from the narrow slot 4. When it is necessary to discharge the material, the motor 16 drives the rotating rod 7 to rotate, and the rotating rod 7 drives each lever 8 to rotate. During the rotation, the lever 8 repeatedly passes through the slot 4 to shift a small amount of waste in the material box 3. The waste is deformed by force and is shifted out of the slot 4 by the lever 8. Then, as the motor 16 drives the lever 8, the waste in the material box 3 falls in batches one by one and falls from the opening of the heating box 10 into the bottom of its inner cavity, and cooperates with the motor 2 16 to drive the rotating shaft 14 to rotate, and the rotating shaft 14 drives the cam 15 to rotate. When the raised part of the cam 15 is upward, it lifts the left side of the heating box 10. At this time, the heating box 10 is automatically The waste material in the heating box 10 is tilted downward from left to right, and then falls into the heating box 10, and slides to the right along the inclined surface. When the raised part of the cam 15 is downward, the left side of the heating box 10 falls onto the support column 17. At this time, the heating box 10 is in a horizontal state and no longer tilted. At this time, the waste material will not move, and then in the interval of each batch of waste falling, the heating box 10 can be tilted in an orderly manner to move the waste material in the heating box 10 to the right as a whole, and then after each batch of waste material falls into the heating box, it will not be piled together, but will be in a spread out state, and this continues until the waste material as a whole moves to the filter screen 12. When melting is required, a device for collecting liquid waste is placed under the discharge pipe 20 in advance, and the electric heating pipe 11 is started to heat up. The high temperature evenly dissolves the waste material spread on the filter screen 12, and the liquid waste passes through the mesh of the filter screen 12, falls and gathers in the collection cover 19, and is discharged from the discharge pipe 20 and falls into the collection device.
