Technical Field

[0001] The utility model relates to the technical field related to plastic granule manufacturing, and in particular to a comprehensive drying device. Background Art

[0002] After the mineral water bottles are recycled, they need to be made into plastic pellets for recycling. The production process is as follows: the raw materials are heated by a spiral extruder and then extruded. After extrusion, they are cooled into plastic strips by a water cooling device. The plastic strips enter the air drying device after the water cooling device, and the air flow is used to dry the moisture attached to the surface of the plastic strips. Finally, they enter the pelletizing device and are bagged and packaged.

[0003] my country's utility model patent "Plastic Strip Air-Drying Device" with publication number CN210282945U discloses a plastic strip air-drying device, which uses an adjusting component to adjust the width of the air outlet, and the air outlet and the blowing roller assembly dry the upper and lower parts of the plastic strip, thereby improving the dryness of the plastic strip; uses a conveying roller to support the plastic strip to increase the stability of the plastic strip transmission; uses two air outlets, an adjusting component and a blowing roller assembly to perform double-layer blowing on the plastic strip, thereby further increasing the degree of drying of the plastic strip.

[0004] However, the above patent still has the following shortcomings: in the continuous granulation process, the time for the plastic strips to pass through the air drying device is within 1-3 seconds. Although more than 95% of the moisture can be blown off by the air drying device, moisture will still exist on the surface of the plastic strips. Therefore, it is necessary to design a comprehensive drying device. Utility Model Content

[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-6 As shown, a comprehensive drying device comprises: a mounting frame 1, a wiper unit mounted on the mounting frame 1, and an air drying unit mounted on the mounting frame 1 and located on a side of the wiper unit close to a discharge end;

[0031] The wiper unit includes a horizontal strip-shaped lower base 2 fixedly mounted on a mounting frame 1, a strip-shaped upper base 3 located above the lower base 2 and matching the lower base 2, a connecting piece 5 connected to one end of the upper base 3 via a horizontal hinge shaft 4, a plurality of lower half rubber sleeves 6 arranged at intervals along the length direction of the lower base 2 and all removably mounted on the lower base 2, and a plurality of upper half rubber sleeves 7 arranged at intervals along the length direction of the upper base 3 and all mounted on the upper base 3 and respectively capable of matching with the corresponding lower half rubber sleeves 6, the connecting piece 5 is mounted on the mounting frame 1 via a mounting mechanism, and the end of the upper base 3 away from the hinge shaft 4 is detachably connected to the mounting frame 1 via a connecting mechanism.

[0032] After passing through the water cooling device, the plastic strip passes through the corresponding upper rubber sleeve 7 and lower rubber sleeve 6. The cooperation of the upper rubber sleeve 7 and the lower rubber sleeve 6 can scrape off more than 85% of the moisture on the surface of the plastic strip. After passing through the wiper unit, the plastic strip enters the air-drying unit. At this time, there is less moisture attached to the surface of the plastic strip, so the moisture attached to the surface of the plastic strip can be completely blown dry when passing through the air-drying unit. After setting the wiper unit, the energy consumption of the air-drying unit can also be reduced.

[0033] When manual material feeding and threading is required in the early stage of production, the unit of the upper base 3 away from the mounting mechanism is separated from the mounting frame 1 through the connecting mechanism, and the upper base 3 is rotated around the hinge shaft 4 to facilitate the movement of several plastic strips between the upper base 3 and the lower base 2, and each plastic strip is moved into the corresponding lower rubber sleeve 6 respectively, and then the upper base 3 is rotated around the hinge shaft 4 so that the upper rubber sleeve 7 and the corresponding lower rubber sleeve 6 are matched and sleeved on the outside of the plastic strip, and then the end of the upper base 3 is connected to the mounting frame 1 through the connecting mechanism.

[0034] The upper rubber sleeve 7 and the corresponding lower rubber sleeve 6 form a closed rubber sleeve, and the diameter of the middle through hole of the rubber sleeve gradually decreases in the direction approaching the air-drying unit.

[0035] The upper rubber sleeve 7 and the lower rubber sleeve 6 will gradually wear out after use, so the diameter of the middle through hole of the rubber sleeve is set to gradually decrease in the direction close to the air-drying unit, which can extend the service life.

[0036] The air drying unit includes a drying box 8 fixedly mounted on a mounting frame 1, at least one air intake fan 9 fixedly mounted on the bottom of the drying box 8, and a heating tube 10 installed in a circuitous manner inside the drying box 8. An air outlet 11 is provided on the top of the drying box 8, and a mounting notch 12 is provided on the side wall of the drying box 8 for a plastic strip to pass through and move to above the heating tube 10.

[0037] The air drying unit dries the water attached to the surface of the plastic strip by hot air, which can improve the drying quality. The function of the installation notch 12 is to allow the plastic strip to move through the installation notch 12 to just above the heating tube 10 during the material feeding process.

[0038] The mounting mechanism includes a mounting seat 13 fixedly mounted on the mounting frame 1 , the connecting member 5 is vertically slidably connected to the mounting seat 13 , a vertical adjusting bolt 14 is connected to the bottom of the mounting seat 13 via a bearing, and the adjusting bolt 14 passes through the connecting member 5 in a threaded manner.

[0039] The connecting member 5 can be driven to slide vertically on the mounting seat 13 by adjusting the bolt 14, that is, the height between the connecting member 5 and the lower base 2 can be adjusted, thereby adjusting the squeezing force of the upper rubber sleeve 7 and the lower rubber sleeve 6 on the plastic strip.

[0040] The connecting mechanism includes a connecting plate 15 fixedly mounted on the end of the upper base 3, a threaded rod 17 assembled on the mounting frame 1 through a hinge seat 16, and a butterfly nut 18 threadedly mounted on the threaded rod 17 and capable of abutting against the upper surface of the connecting plate 15. The connecting plate 15 is provided with a connecting notch for the threaded rod 17 to pass through.

[0041] Before feeding, loosen the butterfly nut 18 and move the threaded rod 17 out of the connecting notch, so that the upper base 3 can rotate around the hinge axis 4 away from the lower base 2; after feeding is completed, rotate the upper base 3 around the hinge axis 4 close to the lower base 2, and then rotate the threaded rod 17 around the hinge seat 16 to move the threaded rod 17 into the connecting notch, and rotate the butterfly nut 18 so that it tightly contacts the upper surface of the connecting plate 15.

[0042] A horizontal support bar 19 is fixedly mounted on the upper side of the installation notch 12, and at least one set of support mechanisms located below the support bar 19 is mounted on the lower side of the installation notch 12;

[0043] The support mechanism includes a threaded seat fixedly mounted on the lower side wall of the installation notch 12 and a support bolt 20 threadably passing through the threaded seat and having a top that can contact the support bar 19 .

[0044] Before feeding, rotate the support bolt 20 so that the top of the support bolt 20 moves downward to facilitate the plastic strip to move into the installation gap 12; after feeding, rotate the support bolt 20 so that the top of the support bolt 20 contacts the support strip 19 to avoid deformation of the drying box 8.

[0045] The lower rubber sleeve 6 is assembled on the lower base 2 through a first mounting member, and the upper rubber sleeve 7 is assembled on the upper base 3 through a second mounting member having the same structure as the first mounting member.

[0046] Both ends of the lower rubber sleeve 6 are provided with flanges, and the first mounting component includes a pair of gaskets 21 that can respectively fit the outside of the flanges and a plurality of mounting bolts 22 that pass through the pair of gaskets 21, the pair of flanges and the lower base 2.

[0047] By loosening and removing the mounting bolts 22, the lower rubber sleeve 6 can be removed, and a pair of gaskets 21 are respectively attached to the two ends of the replaced lower rubber sleeve 6, and then the lower rubber sleeve 6 is installed on the lower base 2 through the mounting bolts 22. The replacement is convenient and quick. The replacement method of the upper rubber sleeve 7 is the same as that of the lower rubber sleeve 6.
