DETAILED DESCRIPTION

Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Rotating rings 11 are installed at both ends of the transverse roller 3, and a guide groove 15 is opened on one side of the rotating ring 11 close to the end surface of the transverse roller 3, and a limiting guide block 16 is evenly installed inside the guide groove 15, and one end of the limiting guide block 16 is connected to the inner wall of the transverse roller 3, and a cleaning roller 14 is evenly connected to the opposite side between the two rotating rings 11, and the outer side of the cleaning roller 14 is against the inner wall of the transverse roller 3;

[0024] The limiting guide blocks 16 are distributed in an annular shape with equal spacing inside the transverse roller 3. The rotating ring 11 forms a rotating structure with the transverse roller 3 through the cooperation of the guide groove 15 and the limiting guide blocks 16. At the same time, a rotating mechanism 17 is arranged inside the rotating ring 11 on one side.

[0025] The rotating mechanism 17 includes an inner gear ring 1701 installed inside the rotating ring 11, and a gear 1702 is meshed inside the inner gear ring 1701, a connecting shaft 1703 penetrates inside the gear 1702, and one end of the connecting shaft 1703 extends to the outside of the transverse roller 3 and is installed with a rotating wheel 1704;

[0026] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when in use, the external rotating wheel 1704 is used to control the rotation of the internal rotating ring 11, and the friction cooperation of multiple cleaning rollers 14 is combined to achieve cyclic friction on the inner wall of the transverse roller 3, so that the cleaning roller 14 can push the material attached to the inner wall toward the direction of the inlet and outlet pipe 6 to reduce waste;

[0027] A feed-in and feed-out pipe 6 is installed at the top of the transverse roller 3, and a sealing cover 7 is provided on the external threaded sleeve of the feed-in and feed-out pipe 6. A heating chamber 4 is opened on the inner wall of the transverse roller 3, and the interior of the heating chamber 4 is evenly filled with a heating wire 5 to achieve heating of the inner cavity of the transverse roller 3. A fixed sleeve 9 is provided on a section of the rotating shaft 8 located in the inner cavity of the transverse roller 3, and a radial stirring mechanism 10 is evenly provided on the outside of the fixed sleeve 9. The radial stirring mechanism 10 includes a guide rod 1001 welded to the outer side of the fixed sleeve 9;

[0028] The guide rods 1001 are distributed in a cross shape on the fixed sleeve 9, and the length of the guide rods 1001 is less than the inner radius length of the transverse roller 3;

[0029] A guide hole 1002 is formed at the outer end of the guide rod 1001. The guide hole 1002 penetrates the sliding block 1003. A sliding sleeve 1004 is sleeved on the outer side of the guide rod 1001.

[0030] The sliding sleeve 1004 forms a sliding structure with the guide rod 1001 under the cooperation of the sliding block 1003 and the guide hole 1002, and buffer pads are arranged at both ends of the sliding block 1003;

[0031] The two sides of the sliding sleeve 1004 are connected to the two outer sides of the sliding block 1003 respectively, and the two sides of the sliding sleeve 1004 are installed with fan blades 1005;

[0032] The fan blades 1005 are located on both sides of the sliding sleeve 1004 close to the end surface of the transverse roller 3, and the two fan blades 1005 are in a V-shaped structure;

[0033] Specifically, Figure 1 , Figure 3 As shown, when in use, the buffer pad is used to reduce the impact between the two ends of the sliding block 1003 when sliding inside the guide hole 1002, thereby preventing damage to the sliding block 1003 and increasing its service life. The fan blades 1005 and the inclined plate 13 are used to increase the direct contact and impact with the material, increase the dispersion of the material, and improve the mixing effect between the toughening agent and the raw material.

[0034] Working principle: When the utility model is used, the sealing cover 7 is firstly screwed to make the inlet and outlet pipes 6 open at the top, and then the toughening agent and the HIPS raw material are introduced into the interior of the transverse roller 3. After the sealing cover 7 is covered, the heating guide wire 5 is started to heat the interior of the transverse roller 3, and the servo motor 12 is started synchronously to make the rotating shaft 8 drive the transverse roller 3 to rotate, so that the toughening agent and the HIPS raw material inside are tumbled and mixed;

[0035] Secondly, during the rotation of the rotating shaft 8, the fixed sleeve 9 is synchronously driven to rotate, thereby causing the radial stirring mechanism 10 to rotate. Since the sliding block 1003 slides inside the guide hole 1002, the sliding block 1003 uses the gravity and centrifugal force of the sliding block 1003. When the guide rod 1001 rotates from the upper end to the lower end, the sliding block 1003 drives the sliding sleeve 1004 to slide along the direction of the guide rod 1001, so that the fan blades 1005 move synchronously, so that the fan blades 1005 perform additional radial collisions on the tumbling materials to promote the stirring direction, and utilize the action of the inclined plate 13 to cause the materials to collide and stir in different directions, so as to promote the multi-directional tumbling of the materials inside the transverse drum 3, thereby improving the stirring effect;

[0036] Finally, the feed pipe 6 is adjusted to the bottom position to facilitate the dumping of the material, and by rotating the wheel 1704, 170 drives the gear 1702 to rotate. Since the gear 1702 is meshed with the inner gear ring 1701, the inner gear ring 1701 drives the rotating ring 11 to rotate, and the cleaning roller 14 rolls and rubs along the inside of the transverse roller 3, so as to transfer the material adhering to the inside to the feed pipe 6, so as to improve the unloading effect.
