[0002] Plastic bags are usually made of polyethylene (PE), including low-density polyethylene (LDPE), high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). These raw materials are usually processed in the form of particles. When producing plastic bags with colors or additives, it is necessary to add pigment masterbatch or other functional additives such as antistatic agents, ultraviolet absorbers, etc. to the plastic particles, so mixing operations are required. In the prior art, mixers are generally used for processing. However, the existing mixers have the following problems:

[0003] The stirring and mixing structure of the existing mixer is relatively simple, and generally mixing is performed only by stirring blades, which may cause the problem of uneven mixing.

[0004] When in use, the problem of uneven wall thickness may occur on both the inner and outer sides of the mixer. The inner wall of the mixer is usually thicker on the inside due to the undischarged raw materials condensing on the inner wall of the mixer after cooling, while the outer wall of the mixer is usually thicker on the outside due to pollutants such as dust or impurities adhering to the outer wall of the mixer. Since heating is required during mixing, the locally thicker parts are prone to high thermal stress, resulting in local thermal deformation. Based on this, the present invention designs a plastic bag processing device. Summary of the invention

DETAILED DESCRIPTION

[0028] Reference Figure 1-7 , a plastic bag processing device, comprising:

[0029] A base 1, in which a discharge channel 9 is provided, and the other side of the discharge channel 9 is located on the side of the base 1 and is connected to a discharge pipe 10, and the discharge pipe 10 is used to discharge the raw materials in the mixing box 2;

[0030] The mixing box 2 is configured as a cylindrical structure with an opening at the top. The mixing box 2 is fixedly connected to the base 1. A rotating plate 11 is rotatably connected to the top opening of the mixing box 2. The rotating plate 11 seals the top opening of the mixing box 2.

[0031] The support platform 3 is fixedly connected to the side of the base 1, the upper side of the support platform 3 is connected to the top of the mixing box 2 and is passed through a feed pipe 4, the feed pipe 4 coaxially passes through the rotating plate 11, and one end of the feed pipe 4 located in the mixing box 2 is connected to a one-way valve 13, and the raw materials are input into the mixing box 2 through the feed pipe 4;

[0032] The inner stirring component 5 and the outer cleaning component 6 are connected to the outer cleaning component 6 through a plurality of annular mounting frames 7 arranged on the outside of the mixing box 2, each mounting frame 7 is fixedly connected to the rotating plate 11, and a turntable 8 is commonly connected to the bottom of the plurality of mounting frames 7, which is embedded in the top of the base 1 and coaxially arranged with the mixing box 2. The turntable 8 is driven to rotate by a driving motor arranged in the base 1 and drives the mounting frame 7 and the outer cleaning component 6 to rotate. The outer cleaning component 6 includes a plurality of mounting rods 61, each mounting rod 61 is mounted on the side of a mounting frame 7, each mounting rod 61 is connected to a connecting plate 62, each connecting plate 62 is arranged along the radial direction of the mixing box 2, each connecting plate 62 is connected to a brush 63 and is against the outer wall of the mixing box 2 through the brush 63, and the outer wall of the mixing box 2 is cleaned by rotation and friction through the brush 63.

[0033] The internal stirring assembly 5 includes a stirring blade 51 and an auxiliary part 52 connected to the outside of the feed pipe 4. The stirring blade 51 can achieve the effect of preliminary mixing of the raw materials in the mixing box 2. The auxiliary part 52 can assist the part 52 to stir evenly and clean the inner wall of the mixing box 2 at the same time. The part of the feed pipe 4 located outside the mixing box 2 is connected to a gear 1 54, and the gear 1 54 is meshed with a gear 2 55. The gear 2 55 is connected to a rotating motor 56, and the rotating motor 56 is installed on the support platform 3. The auxiliary part 52 includes a plurality of slide rails 521, each of which is connected to a slider 522. The bottom of the slider 522 is connected to a secondary shaft 523, and a plurality of stirring plates 524 are installed on the outer side of the secondary shaft 523. The other end of the plurality of stirring plates 524 is connected to an abutment layer 525, and the abutment layer 525 is made of a rubber material that expands when heated. When the stirring plate 524 rolls to the inner wall of the mixing box 2, the inner wall of the mixing box 2 can be cleaned by the abutment layer 525. The bottom of each mounting frame 7 is connected to the turntable 8 through a mounting block 12 and bolts. The turntable 11 is penetrated by a plurality of limit grooves 529 that meet the radial movement of the secondary shaft 523 along the turntable 11. The limit grooves 529 The slider 522 is in a state of movable sealing. A reciprocating screw 526 is provided through the slider 522, so that when the reciprocating screw 526 rotates in one direction, the slider 522 reciprocates on the slide rail 521. The other end of the reciprocating screw 526 passes through the mounting frame 7 and is connected to a matching wheel 528. The matching wheels 528 on multiple mounting frames 7 are commonly connected to a helical gear turntable 527. When the matching wheel 528 rotates around the helical gear turntable 527, it will rotate itself, thereby driving the reciprocating screw 526 to rotate. The helical gear turntable 527 is sleeved on the outer side of the feed pipe 4, and the helical gear turntable 527 is fixedly connected to the inner top of the bracket 3. The auxiliary part 52 is connected with a rolling part 53 that makes the secondary shaft 523 roll. The rolling part 53 includes a rotating wheel 531 sleeved on the secondary shaft 523. The rotating wheel 531 is wrapped with an elastic rope 532. The two ends of the elastic rope 532 are respectively fixedly connected to the two sides of the slide rail 521. The elastic rope 532 is in a taut state. The rotating wheel 531 is rotatably connected to the bottom of the slider 522. In this way, when the slider 522 moves, the rotating wheel 531 is driven to move. When the rotating wheel 531 moves, the elastic rope 532 connected to it will drive the rotating wheel 531 to rotate, thereby driving the secondary shaft 523 and the stirring plate 524 to rotate.

[0034] When the present invention is in use, the turntable 8 outputs rotation to the multiple mounting frames 7, so that the multiple mounting frames 7 revolve around the mixing box 2, and each mounting frame 7 is connected to a matching wheel 528, so that the matching wheel 528 rotates when it revolves around the mixing box 2 synchronously, thereby driving the reciprocating screw 526 to rotate, and the reciprocating screw 526 will drive the slider 522 to slide back and forth on the slide rail 521, so that the secondary shaft 523 and the stirring plate 524 connected to the slider 522 will move along the radial direction of the mixing box 2, and at the same time, under the action of the rolling part 53 connected to the secondary shaft 523, the secondary shaft 523 itself rotates when it moves, that is, the effect of multiple stirring plates 524 rolling and mixing along the radial direction of the mixing box 2 is achieved, so that the rotation of the mounting frame 7 is coordinated, and the range of action of the stirring plate 524 is effectively increased, ensuring that the added ingredients are evenly distributed among the plastic particles.

[0035] An abutment layer 525 is arranged on the outer side of the stirring plate 524 in the auxiliary part 52, and the abutment layer 525 is made of a rubber material that expands when heated. When the multiple stirring plates 524 roll radially along the mixing box 2, the multiple mounting frames 7 will drive the stirring plates 524 to roll close to the inner wall of the mixing box 2, and will frictionally clean the inner wall of the mixing box 2 to avoid a lot of material accumulation on the inner wall of the mixing box 2, thereby affecting the mixing effect. At the same time, the external cleaning component 6 located on the outside of the mounting frame 7 can simultaneously clean the outer side surface of the mixing box 2. The advantage of this is that it avoids the outer wall of the mixing box 2 having thick dust, which on the one hand affects the heat dissipation of the mixing box 2, and on the other hand causes the mixing box to deform due to the different wall thicknesses, thereby affecting the service life of the device.
