[0045] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0048] The filler assembly 3 is used to inject paper fiber slurry into the forming mold 2;

[0049] The suction and blowing assembly 4 is used to suck moisture from the paper fiber slurry in the forming mold 2 and blow and flatten the outer surface of the paper fiber tube 7 after the moisture is sucked out;

[0050] The demoulding assembly 5 is used to drive the outer mold a201, the outer mold b202 and the core rod 203 to separate from the paper fiber tube 7 and cooperate with the receiving assembly 6 to receive and transfer the demoulded paper fiber tube 7.

[0051] When the present invention is working, the forming mold 2 moves to the filling component 3, stops and cooperates with the filling component 3 to inject paper fiber slurry. After the filling is completed, the forming mold 2 continues to move, and the suction and blowing component 4 sucks moisture from the paper fiber slurry in the forming mold 2 and blows and presses the outer surface of the paper fiber tube 7 after the moisture is sucked out. Finally, the forming mold 2 stops at the demolding component 5, cooperates with the demolding component 5 to separate the outer mold a201, the outer mold b202 and the core rod 203 from the paper fiber tube 7, and cooperates with the receiving component 6 to receive and transfer the demolded paper fiber tube 7. Finally, the forming mold 2 starts the next round of repeated operations, and the cycle is repeated.

[0052] Here, the forming mold 2 of the present invention is arranged on the rotating device 1 for rotating and cyclic movement, and the forming mold 2 includes a vertically arranged outer mold a201, an outer mold b202 and a core rod 203. The outer mold a201 and the outer mold b202 are cavity settings and have a plurality of through holes 204 on the inner wall. The cavities of the outer mold a201 and the outer mold b202 are respectively connected to the hollow tube a205 and the hollow tube b206. The initial forming of the paper fiber tube 7 is completed by injecting raw materials into the vertically arranged outer mold a201, the outer mold b202 and the core rod 203, and then the formed paper fiber slurry is subjected to moisture extraction and the outer surface of the paper fiber tube 7 after the moisture extraction is completed is blown and flattened, and finally demolding and transfer are performed. The continuous operation improves the degree of automation of the equipment, improves the production efficiency, improves the overall quality of the paper fiber tube, and the wall thickness and specific gravity of the raw materials are more uniform than the existing horizontal slurry suction production.

[0053] See attached Figure 1 and attached Figure 3 Specifically, the molding mold 2 also includes a fixed base 207 fixedly connected to the rotating device 1, and a mold bearing seat 208 is slidably arranged on the fixed base 207. The mold bearing seat 208 is used to carry the outer mold a201 and the outer mold b202. The outer wall sides of the outer mold a201 and the outer mold b202 are connected with sliding limit rods 209, and the sliding limit rods 209 are slidably arranged on the mold bearing seat 208. The two ends of the sliding limit rods 209 are also fixedly connected with blocks a210. The outer end of the fixed base 207 is fixedly connected with a supporting pulley 211, and a matching supporting guide rail 212 is arranged on the moving path of the supporting pulley 211. A matching supporting slide groove 213 is arranged on the moving path of the rotating device 1. The support cooperation between the supporting wheel 211 and the supporting guide rail 212 ensures the stability of the molding mold 2 during the rotational movement, and the setting of the supporting slide groove 213 also ensures the operating stability of the rotating device 1.

[0054] See attached Figure 3 , Attachment Figure 5 and attached Figure 6 Specifically, the hollow tube a205 is also fixedly connected with a water pumping interface a214 and a blowing interface a215, and the connecting ports between the hollow tube a205 and the hollow tube b206 and the cavities of the outer molds a201 and b202 are elastically provided with wind dispersion rings 216, and the wind dispersion ring 216 is provided with a trumpet-shaped air outlet 217 in the circumferential direction. The wind dispersion ring 216 is connected to the connecting port by a reset spring, and the trumpet-shaped air outlet 217 is more conducive to the diffusion of wind force over a larger range.

[0055] It should be pointed out that the connection ports between the hollow tube a205 and the hollow tube b206 of the present invention and the cavities of the outer mold a201 and the outer mold b202 are elastically provided with a dispersion ring 216, and a trumpet-shaped air outlet 217 is provided in the circumferential direction of the dispersion ring 216. The trumpet-shaped design is conducive to a larger and more uniform angle range of the wind force blown out by the suction and blowing assembly during the blowing and flattening, and is more conducive to flattening the ridges on the surface of the paper tube (such as Figure 5 As shown in FIG. 2 , when the water is sucked out, the elastically arranged air dispersion ring 216 is pulled outward due to the strong adsorption force, and the air dispersion ring 216 and the upper and lower sides of the tube wall form a circle of water discharge channels (as shown in FIG. Figure 6 As shown), the efficiency of water discharge is accelerated.

[0056] See attached Figure 1 and attached Figure 7 Specifically, the filling assembly 3 includes a storage tank 301 arranged on the upper side of the rotary device 1 and a discharger 302 arranged just above the moving path of the forming mold 2. A water pump 303 is connected between the storage tank 301 and the discharger 302. A conical discharge port 304 is arranged on the lower end surface of the discharger 302. A receiving port 305 matching the conical discharge port 304 is arranged on the upper end surface of the core rod 203. A cylinder a306 and a cylinder a307 are also arranged below the discharger 302. 6 pushes the push block 307, and the cylinder a306 drives the push block 307 to push the mold bearing seat 208. The mold bearing seat 208 approaches the discharge machine 302 in the vertical direction. After the material receiving port 305 on the core rod 302 contacts with the conical discharge port 304, the raw material begins to be injected into the molding mold 2 through the material receiving port 305. The material of the conical end of the conical discharge port 304 is rubber material. When the material is pressed and contacted with the material receiving port 305 for injection, the rubber material improves the sealing performance.

[0057] See attached Figure 8 and attached Fig. 9 Specifically, the suction and blowing assembly 4 includes a suction and blowing pipe 401 fixedly arranged at the center of the rotating device 1, and the suction and blowing pipe 401 is divided into a water pumping cavity 402 and a blowing cavity 403 from top to bottom. The outer walls of the water pumping cavity 402 and the blowing cavity 403 are respectively provided with a water pumping port 404 and a blowing port 405. The water pumping cavity 402 and the blowing cavity 403 are both hollow and do not communicate with each other. When the molding mold 2 moves counterclockwise driven by the rotating device 1, it first passes through the water pumping port 404 and then passes through the blowing port 405.

[0058] See attached Figure 1 , Attachment Figure 2 and attached Figure 8Specifically, the outer walls of the water pumping cavity 402 and the blowing cavity 403 are also rotatably connected with a water pumping connection disk 406 and a blowing connection disk 407, and the outer walls of the water pumping connection disk 406 and the blowing connection disk 407 are respectively connected with a plurality of water pumping interfaces b408 and blowing interfaces b409. The water pumping cavity 402 is connected with a suction pump 410, and the blowing cavity 403 is connected with a blower 411. The water pumping interface a214, the blowing interface a215 and the water pumping interface b408, the blowing interface b409 are fixedly connected by a telescopic hose 412. The molding mold 2 moves counterclockwise through the telescopic hose 412 to drive the water pumping connection disk 406 and the blowing connection disk 407 to move synchronously on the suction and blowing pipe 401. When the water pumping connection disk 406 rotates to the water pumping port 404, the hollow tube a205 and the hollow tube b206 are in a connected state through the water pumping interface a214 and the water pumping interface b408, and under the action of the suction pump 410, the water is sucked out of the paper fiber tube 7 in the molding mold 2. After the suction is completed, the water pumping connection disk 406 and the blowing connection disk 407 continue to rotate synchronously on the suction and blowing tube 401. When the blowing connection disk 407 rotates to the blowing port 405, the hollow tube a205 and the hollow tube b206 are in a connected state through the blowing interface a215 and the blowing interface b409. Under the action of the blower 411, the paper fiber tube 7 after the water is sucked out of the molding mold 2 is blown and flattened.

[0059] In particular, if the attached Fig.14 As shown, the hollow tube a205 and the hollow tube b206 are provided with three suction and blowing channels a, b, and c from bottom to top. The pumping operation of the suction and blowing component 4 is a segmented operation. The pumping order is to first pump from the bottom a, then from the middle b, and finally from the top c. If the pumping starts from the top c, the water liquid sucked up by the negative pressure at the upper c will not be able to fully flow to the a and b below after the paper tube is formed, resulting in the paper tube parts at a and b not being properly formed, which is not conducive to the pumping operation of the whole process.

[0060] It is worth mentioning that after the suction and blowing assembly 4 of the present invention sucks moisture from the paper fiber slurry in the forming mold 2, the strong adsorption force of the sucked moisture may cause the outer surface of the uncured paper tube after the moisture is sucked out to bulge outwards in the through holes 204 of the outer mold a201 and the outer mold b202 (such as Fig.12 As shown), the forming mold 2 is blown and flattened again by the suction and blowing assembly 4 during the subsequent movement process (as shown in FIG. Fig.13 As shown), the setting of the suction and blowing component 4 ensures that water can be sucked from the paper fiber slurry while also ensuring that the surface of the paper tube is smooth after the water is sucked through blowing and pressure, thereby reducing the defect of surface bulges.

[0061] See attached Fig.10Specifically, the demolding assembly 5 includes a cylinder b501 and a cylinder c502 fixedly arranged on both sides of the moving path of the forming mold 2. The output ends of the cylinder b501 and the cylinder c502 are fixedly connected with a block b503 that cooperates with the block a210. When the forming mold 2 moves to the demolding assembly 5, the blocks a210 at both ends of the sliding limit rod 209 are engaged with the block b503, and then the cylinder b501 and the cylinder c502 push backward to drive the outer mold a201 and the outer mold b202 to separate from the paper fiber tube 7.

[0062] See attached Figure 3 and attached Fig.11 Specifically, the demoulding assembly 5 also includes a demoulding pulley set 504 arranged on the upper end surface of the core rod 203, and a demoulding guide rail 505 that contacts and cooperates with each other is fixedly arranged on the moving path of the demoulding pulley set 504. The demoulding guide rail 505 includes a rising section 506, a stable section 507 and a reset section 508. The demoulding pulley set 504 passes through the demoulding guide rail 505 and drives the core rod 203 to separate from the paper fiber tube 7 under the action of the rising section 506. The stable section 507 is used to maintain the detached state of the core rod 203, and the reset section 508 is used to guide and drive the core rod 203 to return to the molding mold 2.

For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that the receiving assembly 6 includes a lifting sliding seat 601 arranged at the lower end of the fixed base 207, a lifting rod 602 and a pipe mold 603 arranged at the upper end of the lifting rod 602 are slidably arranged on the lifting sliding seat 601, and a matching lifting guide rail 604 is arranged at the lower end of the moving path of the lifting rod 602, and the lifting guide rail 604 includes a lifting guide rail 604. The lifting rod 602 includes an upward section 605, a connecting section 606 and a downward section 607. Under the action of the upward section 605 of the lifting guide rail 604, the connecting section 603 is driven to rise to receive the paper fiber tube 7 after demoulding in the first embodiment. The connecting section 606 is used to maintain the rising state of the connecting section mold 603. The downward section 607 is used to guide and drive the connecting section mold 603 and the paper fiber tube 7 to move downward and return. After the paper fiber tube 7 moves downward and returns, the paper fiber tube 7 can be manually taken out from the connecting section mold 603 on one side of the rotating device 1 to collect the finished products uniformly.
