Therefore, they should not be construed as limiting the present invention. Furthermore, in the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0031] like Figures 1 to 6As shown; A modification system for chlorinated polyethylene (CPE), comprising a tilted body 1, a material port 2 being opened on the left side of the body 1, characterized in that: a sealing ring 3 is fixedly connected to the inner wall of the bottom of the body 1, a barrel 4 is rotatably connected to the inner wall of the body 1, and one end of the barrel 4 is communicated with the material port 2, a support plate 5 is symmetrically fixedly connected to the inner wall of the body 1, the support plate 5 is sleeved inside the barrel 4, the top of the support plate 5 is fixedly connected to a support spring 6, the other end of the support spring 6 is fixedly connected to a sieve plate 7, the outer wall of the body 1 is fixedly connected to a servo motor 8, the outer wall of the barrel 4 is fixedly and evenly fixedly connected to an outer ring gear 9, the main shaft of the servo motor 8 passes through the outer wall of the body 1 to its interior and is fixedly connected to a motor gear 10, and the motor The gear 10 is meshed with the outer ring teeth 9, the inner ring wall of the barrel 4 is evenly fixedly connected with the inner ring teeth 11, the inner wall of the body 1 is rotatably connected with a gear column 12, the gear column 12 is meshed with the inner ring teeth 11, and the bottom of the sieve plate 7 is rotatably connected with a cam column 13, the outer ring walls of the cam column 13 and the gear column 12 are both provided with belt grooves 14, and the belt grooves 14 are transmitted by elastic belts, the inner wall of the body 1 is fixedly connected with a connecting plate 15, the inner ring wall of the connecting plate 15 is provided with a feeding box 16, the top of the sealing ring 3 is provided with a first feeding trough 17, one end of the feeding box 16 is communicated with the interior of the first feeding trough 17, the outer ring wall of the barrel 4 is provided with a second feeding trough 18, the second feeding trough 18 can be communicated with the first feeding trough 17;

[0032] During use, the staff transports the material from the material port 2 to the inside of the barrel 4, and transports the additives that need to be mixed into the feeding box 16, and then starts the servo motor 8 to rotate. The rotation of the servo motor 8 drives the motor gear 10 fixedly connected to the main shaft to rotate, and the rotation of the motor gear 10 drives the outer ring gear 9 engaged with it to rotate, and the outer ring gear 9 drives the barrel 4 fixedly connected to it to rotate. The barrel 4 rotates to turn over the material inside the barrel 4, and while the barrel 4 rotates, the second material groove 18 opened on the outer wall of the barrel 4 will meet with the first material groove 17 opened on the sealing ring 3. The first trough 17 and the second trough 18 overlap, and the feeding box 16 is connected to the first trough 17, so the additive inside the feeding box 16 will enter the first trough, and when the second trough 18 overlaps with the first trough 17, the additive in the first trough 17 will enter the second trough 18, and as the barrel 4 rotates, the first trough 17 and the second trough 18 overlap and separate cyclically, so that as the barrel 4 rotates, all the additives in the feeding box 16 enter the second trough 18, and the additives in the second trough 18 will fall down to the sieve plate under their own gravity. 7, and during the rotation of the barrel 4, the inner ring teeth 11 fixedly connected to the inner ring wall of the barrel 4 also rotate together, and the rotation of the inner ring teeth 11 drives the gear column 12 meshing with it to rotate together, and the cam column 13 is rotatably connected to the bottom of the sieve plate 7, and the outer ring walls of the cam column 13 and the gear column 12 are both provided with belt grooves 14, and the belt grooves 14 are driven by elastic belts, so the rotation of the gear column 12 will drive the cam column 13 to rotate together through the belt, and the eccentric force generated by the rotation of the cam column 13 will cause the cam column 13 to vibrate, and the sieve plate 7 is The sieve plate 7 is supported inside the barrel 4 by the support spring 6, so it can shake and vibrate. Therefore, when the cam column 13 vibrates, the cam column 13 will drive the sieve plate 7 to vibrate together, so that the additives dropped on the sieve plate 7 slide along the vibrating sieve plate 7 and evenly fall downward along the mesh of the sieve plate 7 during the sliding process, and evenly fall on the bottom of the barrel 4, thereby completing the uniform distribution of the additives, so that the materials in the barrel 4 and the additives evenly distributed from the sieve plate 7 can be more evenly mixed, thereby enhancing the mixing effect;

[0033] Furthermore, because the cam column 13 and the gear column 12 are driven by an elastic belt, when the cam column 13 vibrates, even if the distance between the cam column 13 and the gear column 12 changes, the elastic belt can ensure the stability of the rotation of the cam column 13 driven by the gear column 12. In addition, the belt groove 14 can well limit the elastic belt, thereby increasing the stability of the rotation of the cam column 13 driven by the gear column 12.

[0034] After the material mixing is completed, the staff opens the material port 2. Because the machine body 1 is tilted, the barrel 4 is also tilted. Therefore, as the barrel 4 rotates, the mixed material in the barrel 4 will slide along the barrel 4 to the material port 2 under its own gravity, and then be discharged from the barrel 4.

[0035] like Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown; the outer wall of the sieve plate 7 is rotatably connected to a reciprocating screw 19, and the reciprocating screw 19 is rotatably connected to the cam column 13 by a belt, and the bottom of the sieve plate 7 is slidably connected to a cleaning block 20, one end of the cleaning block 20 is penetrated by the reciprocating screw 19, and the inner wall of the cleaning block 20 where the reciprocating screw 19 penetrates is fixedly connected to a slider 21, and the other end of the slider 21 extends into the thread groove of the reciprocating screw 19 and fits with its inner wall, and the top of the cleaning block 20 is evenly provided with column holes 22, and the bottom inner wall of the column hole 22 is fixedly connected to a pressure spring 23, and the inner wall of the column hole 22 is slidably connected to a guide column 24, and the bottom of the guide column 24 is fixedly connected to the top of the pressure spring 23, and the other end of the guide column 24 is arc-shaped and can be inserted into the mesh of the sieve plate 7;

[0036] When in use, when the cam column 13 rotates, the reciprocating screw 19 will be driven to rotate through the belt. The reciprocating screw 19 is a screw that can make the slider 21 realize reciprocating motion without changing the rotation direction of the main shaft. Therefore, when the reciprocating screw 19 rotates, the reciprocating screw 19 will drive the slider 21 to make reciprocating linear motion, and the movement of the slider 21 will drive the cleaning block 20 to make reciprocating linear motion. During the movement of the cleaning block 20, when the guide post 24 on the cleaning block 20 coincides with the mesh of the sieve plate 7, the guide post 24 will be bounced into the mesh of the sieve plate 7 under the elastic force of the pressure spring 23, so that the guide post 24 will push the material in the mesh of the sieve plate 7 out, thereby preventing the material from pushing the sieve plate 7 out. The mesh is clogged, and the mesh of the sieve plate 7 is clogged, causing the material on the sieve plate 7 to be unable to evenly fall from the mesh of the sieve plate 7 into the inside of the barrel 4. As the cleaning block 20 moves, the guide post 24 is also moving. When the guide post 24 moves, the inner wall of the mesh of the sieve plate 7 pushes the outer wall of the inclined guide post 24, so that the guide post 24 squeezes the pressure spring 23, so that the guide post 24 slides along the inner wall of the post hole 22, so that the guide post 24 is pulled out of the mesh of the screen, and as the cleaning block 20 moves, it is inserted into the mesh of the next row of sieve plates 7, and the cycle is repeated, so that the guide post 24 cleans the mesh of the sieve plate 7 in turn to prevent the mesh of the sieve plate 7 from being clogged.

[0037] like Figures 1 to 4As shown; the inner ring wall of the connecting plate 15 is rotatably connected to the outer ring wall of the feeding box 16, and the inner ring wall of the first material trough 17 is fixedly connected to the stirring rod 25, the outer ring wall of the feeding box 16 is evenly fixedly connected to the transmission rod 26, and the outer ring wall of the barrel 4 is fixedly connected to the push rod 27, and the push rod 27 can push the transmission rod 26;

[0038] During use, when the barrel 4 rotates, the barrel 4 drives the push rod 27 to rotate together. During the rotation process, the push rod 27 will push the transmission rod 26, so that the transmission rod 26 pushed by the push rod 27 drives the feeding box 16 to rotate, and the interior of the first material trough 17 is fixedly connected to the stirring rod 25, so when the feeding box 16 rotates, the feeding box 16 drives the material inside the feeding box 16 to rotate together, while the stirring rod 25 cannot rotate, so the stirring rod 25 stirs the material inside the feeding box 16, thereby preventing the material from getting stuck inside the feeding box 16 and unable to slide into the interior of the first material trough 17.

[0039] like Figure 6 As shown; both ends of the slider 21 are inclined;

[0040] When in use, both ends of the slider 21 are designed to be inclined, so that when the slider 21 moves along the inner wall of the thread groove of the reciprocating screw 19, the two ends of the slider 21 can respectively act as a "shovel" on the inner wall of the thread groove of the reciprocating screw 19, and can scratch and clean the inner wall of the thread of the reciprocating screw 19, thereby preventing material from sticking to the thread groove of the reciprocating screw 19, causing the material to push and jam the slider 21 in the thread groove of the reciprocating screw 19, causing the slider 21 to be unable to move along the inner wall of the thread groove of the reciprocating screw 19.

[0041] like Figures 2 to 5 As shown; the inner wall of the barrel 4 is fixedly connected with an inclined stirring plate 28;

[0042] A brush 29 is fixedly connected to the inner wall of the body 1 , and the bristles of the brush 29 are in contact with the inner wall of the barrel 4 , and the bristles of the brush 29 can be moved by the stirring plate 28 ;

[0043] When in use, the inner wall of the barrel 4 is evenly fixedly connected to the inclined stirring plate 28. When the barrel 4 rotates to turn the material, the stirring plate 28 can block the material, so that when the barrel 4 turns the material, the stirring plate 28 can make the turning effect of the material better. In order to prevent the powdered material from adhering to the inner wall of the barrel 4 during mixing, resulting in poor mixing effect of the powdered material and the material, a brush 29 is fixedly connected to the inner wall of the body 1. The bristles of the brush 29 are in contact with the inner wall of the barrel 4, so when the barrel 4 rotates, the bristles of the brush 29 will clean the inner wall of the barrel 4, so that the swept powdered material falls to the bottom of the barrel 4, thereby increasing the mixing effect of the powdered material, and when the stirring plate 28 rotates with the barrel 4, the stirring plate 28 will stir the bristles of the brush 29, so that the material adhered to the bristles of the brush 29 is shaken off, thereby preventing the material from adhering to the bristles of the brush 29.

[0044] like Figure 5 As shown; the inner wall of the belt groove 14 is fixedly connected with a baffle 30;

[0045] When in use, a baffle 30 is fixedly connected to the inner wall of the belt groove 14. The baffle 30 will block the elastic belt inside the belt groove 14, thereby preventing the elastic belt from falling off from the belt groove 14, causing the gear column 12 to be unable to drive the cam column 13 to rotate through the elastic belt, thereby causing the screen plate 7 to be unable to vibrate.

[0046] A method for modifying chlorinated polyethylene (CPE), which is applicable to any of the above-mentioned chlorinated polyethylene (CPE) modification systems, comprises the following steps:

[0047] S1: The staff will calculate the ratio of chlorinated polyethylene (CPE) and various modification additives and weigh them;

[0048] S2: The staff delivers all the chlorinated polyethylene (CPE) weighed in S1 from the feed port 2 into the barrel 4, and delivers all the weighed modified additives into the feeding box 16;

[0049] S3: The staff then starts the servo motor 8 to rotate. The rotation of the servo motor 8 drives the present invention to automatically and evenly spread the modified additive into the interior of the barrel 4, and after the chlorinated polyethylene (CPE) and the modified additive in the barrel 4 are fully mixed, the mixture is discharged from the barrel 4 to obtain:

[0050] S4: The staff uses an internal mixer to mix the mixture obtained in S3 to obtain modified chlorinated polyethylene (CPE).

[0051] Working principle of the present invention:

[0052] Refer to the instruction manual Figure 1-6 As shown, the staff transports the material from the material port 2 to the inside of the barrel 4, and transports the additives that need to be mixed into the feeding box 16, and then starts the servo motor 8 to rotate. The rotation of the servo motor 8 drives the motor gear 10 fixedly connected to the main shaft to rotate, and the rotation of the motor gear 10 drives the outer ring gear 9 engaged with it to rotate, and the outer ring gear 9 drives the barrel 4 fixedly connected to it to rotate. The rotation of the barrel 4 turns the material inside the barrel 4, and while the barrel 4 is rotating, the second material groove 18 opened on the outer wall of the barrel 4 will overlap with the first material groove 17 opened on the sealing ring 3. , and the feeding box 16 is connected to the first trough 17, so the additive inside the feeding box 16 will enter the inside of the first feeding box, and when the second trough 18 overlaps with the first trough 17, the additive in the first trough 17 will enter the second trough 18, and as the barrel 4 rotates, the first trough 17 and the second trough 18 are cyclically overlapped and separated, so that as the barrel 4 rotates, all the additives in the feeding box 16 enter the second trough 18, and the additives in the second trough 18 will fall downward to the bottom of the sieve plate 7 under their own gravity. The top of the barrel 4 rotates, and the inner ring wall of the barrel 4 rotates with the fixed inner ring teeth 11, and the rotation of the inner ring teeth 11 drives the gear column 12 meshing with it to rotate together, and the cam column 13 is rotatably connected to the bottom of the sieve plate 7, and the outer ring walls of the cam column 13 and the gear column 12 are provided with belt grooves 14, and the belt grooves 14 are driven by elastic belts, so the rotation of the gear column 12 will drive the cam column 13 to rotate together through the belt, and the eccentric force generated by the rotation of the cam column 13 will cause the cam column 13 to vibrate, and the sieve plate 7 is The sieve plate 7 is supported inside the barrel 4 by the support spring 6, so it can shake and vibrate. Therefore, when the cam column 13 vibrates, the cam column 13 will drive the sieve plate 7 to vibrate together, so that the additives dropped on the sieve plate 7 slide along the vibrating sieve plate 7 and evenly fall downward along the mesh of the sieve plate 7 during the sliding process, and evenly fall on the bottom of the barrel 4, thereby completing the uniform distribution of the additives, so that the materials in the barrel 4 and the additives evenly distributed from the sieve plate 7 can be more evenly mixed, thereby enhancing the mixing effect;

[0053] Furthermore, because the cam column 13 and the gear column 12 are driven by an elastic belt, when the cam column 13 vibrates, even if the distance between the cam column 13 and the gear column 12 changes, the elastic belt can ensure the stability of the rotation of the cam column 13 driven by the gear column 12. In addition, the belt groove 14 can well limit the elastic belt, thereby increasing the stability of the rotation of the cam column 13 driven by the gear column 12.

[0054] After the material mixing is completed, the staff opens the material port 2. Because the machine body 1 is tilted, the barrel 4 is also tilted. Therefore, as the barrel 4 rotates, the mixed material in the barrel 4 will slide along the barrel 4 to the material port 2 under its own gravity, and then be discharged from the barrel 4.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
