[0018] The present application is further described in detail below in conjunction with the accompanying drawings.

[0019] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the working principle of the existing drum-type continuous drying equipment is first introduced.

[0020] When drying plastic particles, the existing drum-type continuous drying equipment starts the drum-type drying device in advance and preheats the inside of the drum-type drying device, and then pours the plastic particles to be dried into the drum-type drying device, so that the plastic particles can be continuously conveyed during the drying process under the action of the feeding auger inside the drum-type drying device, thereby realizing convenient drying of the plastic particles.

[0021] See also Figure 1-Figure 3 , is a continuous drying device for plastic production disclosed in an embodiment of the present application, including a conveyor frame 4, a split shield 7 is installed in the middle of the top of the conveyor frame 4, the split shield 7 includes a fixed shield 72 and a sliding shield 71, there are two sliding shields 71, the fixed shield 72 is installed in the middle of the top of the conveyor frame 4, and the two sliding shields 71 ​​are installed on both sides of the fixed shield 72; a sliding adjustment mechanism 1 is installed between the top of the fixed shield 72 and the tops of the two sliding shields 71, and the sliding adjustment mechanism 1 includes a linkage plate 11, a support plate 12, and a double-axis electric The double-axis motor 13 is installed in the middle of the top of the fixed baffle 72, the screw 14 is installed at the power output end of the double-axis motor 13, the support plate 12 is installed at the top of the fixed baffle 72 and is located on one side of the double-axis motor 13. The screw 14 and the support plate 12 rotate in coordination. The support plate 12 can provide stable support for the screw 14 and facilitate the stable rotation of the screw 14. The screw sleeve 15 is connected to the end of the screw 14 facing away from the double-axis motor 13, and the linkage plate 11 is installed on the sliding baffle 71 and is connected to the closed end of the screw sleeve 15.

[0022] Specifically, when the internal parts of the split baffle 7 are damaged and need to be repaired and maintained, the dual-axis motor 13 is started first. After the dual-axis motor 13 is started, it will drive the screw 14 to rotate. After the screw 14 rotates, it will move axially along the screw 14 under the action of the threaded transmission, so that the sliding baffle 71 can be driven to move away from the fixed baffle 72 while the screw sleeve 15 moves, ensuring that the internal structures of the fixed baffle 72 and the sliding baffle 71 are exposed. After the sliding baffle 71 is separated from the fixed baffle 72, the staff can repair and maintain the damaged parts inside the device.

[0023] See also Figure 1-Figure 2 A guide assembly 3 is also installed between the bottom end of the sliding baffle 71 and the top end of the conveying frame 4. The guide assembly 3 includes a guide block 31 and a guide groove 32. The guide block 31 is connected to the bottom end of the sliding baffle 71, and the guide groove 32 is opened at the top end of the conveying frame 4.

[0024] As an implementation mode, the guide block 31 slides in cooperation with the guide groove 32 to ensure stable movement of the sliding cover 71 relative to the conveying frame 4 and avoid misalignment of the sliding cover 71 relative to the top of the conveying frame 4 when sliding.

[0025] See also Figure 1 , Figure 2 and Figure 4 A hot air drying mechanism 8 is also installed on the upper part of the fixed shield 72 and each split shield 7. The hot air drying mechanism 8 includes a hot air blower 81 and an air outlet hood 82.

[0026] As an implementation mode, after the hot air blower 81 is started, hot air will be delivered to the air outlet hood 82. The hot air entering the air outlet hood 82 will eventually be sprayed onto the surface of the plastic particles on the upper side of the conveyor belt 53 to achieve drying of the plastic particles.

[0027] See also Figure 1-Figure 2 The hot air blower 81 is installed at the top of the corresponding fixed baffle 72 and the sliding baffle 71, the air outlet hood 82 is located at the upper inner part of the corresponding fixed baffle 72 and the sliding baffle 71, and the bottom of the air outlet hood 82 is a porous structure, and the four corners of the top of the air outlet hood 82 are equipped with connecting rods.

[0028] As an implementation method, the hole at the bottom of the air outlet hood 82 facilitates the convenient discharge of hot air, and the connecting rod on the air outlet hood 82 can realize the suspension of the air outlet hood 82.

[0029] See also Figure 1-Figure 2 A material-dispensing mechanism 9 is also installed in the lower part of the fixed baffle 72 and each split baffle 7. The material-dispensing mechanism 9 includes a material-dispensing shaft 91 and a material-dispensing motor 92.

[0030] As an implementation mode, after the material-dispensing motor 92 drives the material-dispensing shaft 91 to rotate, the plastic particles on the conveyor belt 53 can be shifted under the action of the material-dispensing shaft 91 to facilitate the turning of the plastic particles and ensure that the moisture on the plastic particles can be quickly dried and evaporated.

[0031] See also Figure 2 The material-discharging shaft 91 is installed on the feeding side of the fixed baffle 72 and the sliding baffle 71 , and the material-discharging shaft 91 is connected to the material-discharging motor 92 by a coupling.

[0032] As an implementation mode, the material-discharging motor 92 is mainly used to provide power for the material-discharging shaft 91 to ensure the convenient rotation of the material-discharging shaft 91. Installing the material-discharging shaft 91 on the feed side can ensure that the plastic particles after being moved are in contact with the hot air for a longer time after passing through the sliding baffle 71 and the fixed baffle 72.

[0033] See also Figure 1-Figure 2 A conveying mechanism 5 is also installed on the top of the conveying frame 4. The conveying frame 4 includes a conveying motor 51, a supporting roller 52 and a conveying belt 53. The supporting roller 52 is installed on the upper side of the conveying frame 4, and the conveying belt 53 is sleeved on the outside of the supporting roller 52. The conveying motor 51 is installed on the outer wall of the conveying frame 4 facing one of the supporting rollers 52.

[0034] As an implementation mode, the conveying motor 51 drives the corresponding supporting roller 52 to rotate, and the conveying belt 53 can be rotated under the action of the supporting roller 52, so that the plastic particles can be continuously dried on the conveying belt 53.

[0035] See also Figure 2 A gap is reserved between the bottom end of the material-dispensing shaft 91 and the upper side of the conveyor belt 53 , and a shielding curtain 2 is also installed on the lower part of the side wall of the sliding shield 71 facing away from the fixed shield 72 .

[0036] As an implementation method, the reserved gap can avoid the friction between the material-dispensing shaft 91 and the surface of the conveyor belt 53 when the material-dispensing shaft 91 rotates, and at the same time can realize the convenient dispensing of the plastic particles by the material-dispensing shaft 91.

[0037] See also Figure 1-Figure 2 An operation panel 6 is also installed on the outer wall of the conveying frame 4 on one side of the conveying motor 51 , and the operation panel 6 is electrically connected to the dual-axis motor 13 , the hot air blower 81 and the material-discharging motor 92 .

[0038] As an implementation mode, the operation panel 6 mainly controls the orderly operation of the dual-axis motor 13, the hot air blower 81 and the material-displacing motor 92 by controlling the on-off of the circuit to ensure the efficient drying process of the plastic particles.

[0039] The specific working principle is that when drying the particles used in the production of plastic products, the plastic particles to be dried are first laid on the feed side of the conveyor belt 53, and then the conveying motor 51 drives the supporting roller 52 to rotate, and the conveyor belt 53 is used to convey the plastic particles to the split baffle 7. After passing through the split baffle 7, the plastic particles will be turned over by the action of the material-discharging shaft 91, and at the same time, the hot air blower 81 and the air outlet hood 82 will continuously spray hot air onto the surface of the plastic particles to achieve continuous drying of the plastic particles. The dried plastic particles will eventually be discharged from the discharge side of the conveyor belt 53, and when the internal parts of the split baffle 7 are damaged and need to be repaired and maintained. When the double-axis motor 13 is started, the double-axis motor 13 will drive the screw 14 to rotate after starting. After the screw 14 rotates, it will move axially along the screw 14 under the action of the threaded transmission, so that the sliding baffle 71 can be driven to move away from the fixed baffle 72 while the screw sleeve 15 moves, ensuring that the internal structures of the fixed baffle 72 and the sliding baffle 71 are exposed. After the sliding baffle 71 is separated from the fixed baffle 72, the staff can inspect and maintain the damaged parts inside the device. Since the split baffle 7 on this continuous drying equipment can be automatically opened and closed, the parts inside the device can be quickly presented to the staff, which is convenient for the staff to quickly inspect and maintain.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
