Description

Technical Field

[0001] This utility model relates to the field of pulp molding processing technology, specifically to a pulp molding edge trimming machine. Background Technology

[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper, sugarcane bagasse, bamboo, reeds and other plant fibers as raw materials. The pulp is then processed through pulping, mixing, molding, drying and shaping. The pulp is molded into a certain shape on a molding machine. In some cases, the molding process may result in irregular edges after the pulp is molded, which need to be cut by a molding edge trimmer before it can be used.

[0003] According to the Chinese Patent Publication No. CN104827519B, entitled "A Pulp Molding Edge Trimming Machine," the main components include a bed and a transverse moving mechanism, a longitudinal moving mechanism, a lower mold base, a pressing mechanism, and an upper mold base mounted on the bed. The lower mold base and the upper mold base are matched and, when combined, form a cavity to accommodate the pulp box to be trimmed. The lower mold base is fixed on the longitudinal moving mechanism and can be driven to move longitudinally through the longitudinal moving mechanism. The longitudinal moving mechanism is mounted on the transverse moving mechanism and can be driven to move laterally through the transverse moving mechanism and the upper mold base. The lower mold base is fixed on the pressing mechanism and can be driven to move up and down through the pressing mechanism.

[0004] The aforementioned patent, through its reasonable structural design, enables the pulp molding trimming machine to achieve both moving and rotating shearing functions during operation through the combined movement of the longitudinal and transverse moving mechanisms. Employing mechanical transmission, it fundamentally avoids the pollution risks associated with hydraulic drives. Furthermore, the pulp molding trimming machine boasts a simple structure and convenient operation, ensuring not only the precision and stability of its trimming but also improving production efficiency while reducing production costs. The patented technology integrates the mold base with the moving mechanism, allowing the molded product to directly enter the trimming station without intermediate handling, significantly shortening the production cycle.

[0005] Common pulp molding trimming machines use a moving mechanism that can move laterally and longitudinally, in conjunction with a cutting mechanism, to perform trimming. In this process, the pulp molding first needs to be shaped by a molding machine, and then the pulp is manually or by a robotic arm to be picked up and moved to the die-cutting machine. Then, the single or batch pulp molding is trimmed mechanically or manually. This increases the time from pulp molding to trimming, affecting the efficiency of trimming in mass production. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a pulp molding trimming machine to reduce the time from pulp molding to trimming process and improve the efficiency of trimming in mass production.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a pulp molding and trimming machine, including a base plate, a support, and a top plate. A forward and reverse motor is fixedly connected to the upper end of the top plate. A screw is fixedly connected to the output shaft of the forward and reverse motor. A sliding plate is threadedly connected to the bottom side of the screw. A pressure frame is fixedly connected to one side of the bottom end of the sliding plate. A pressure mold is fixedly connected to the bottom end of the pressure frame by bolts. A first receiving seat is provided on the bottom side of the pressure mold. A first rotating plate is in contact with the upper end of the first receiving seat. A mold groove is opened on the upper end of the first rotating plate. A fixed mold is fixedly connected to the mold groove by bolts. A first connecting plate is fixedly connected to one side of the base plate located on the first receiving seat. A first motor is fixedly connected to one of the first connecting plates. A first rotating rod is fixedly connected to the output end of the first motor. Both sides of the rotating rod are fixedly connected to a first connecting column, which is fixedly connected to one end of the first rotating plate. An electric telescopic rod is fixedly connected to the other side of the bottom of the moving plate. A pressure plate is fixedly connected to the bottom of the electric telescopic rod. A back-shaped cutter is fixedly connected to the bottom of the pressure plate by bolts. A second receiving seat is fixedly connected to the bottom of the pressure plate. A second connecting plate is provided on one side of the second receiving seat. A second motor is fixedly connected to the second connecting plate. A second rotating rod is fixedly connected to the output end of the second motor. Both sides of the second rotating rod are fixedly connected to a second connecting column. A second rotating plate is fixedly connected to one side of the second connecting column. A receiving mold is fixedly connected to the second rotating plate by bolts. A back-shaped cutting groove is opened on the receiving mold, and the back-shaped cutting groove corresponds to the back-shaped cutter.

[0008] As a preferred technical solution of this utility model, a pad is fixedly connected to all four sides of the upper end of the first rotating plate. The pad is made of rubber material and is located outside the fixed mold. By setting the pad, the first rotating plate provides flipping and rotation under the drive of the first motor, thereby transferring the successfully molded pulp to the receiving mold.

[0009] As a preferred technical solution of this utility model, the fixed mold has four receiving holes, and abutment plates are inserted into each of the four receiving holes. A fixed plate is fixedly connected to the bottom end of the abutment plate, and an electric push rod is fixedly connected to the upper end of the fixed plate. The bottom end of the electric push rod is fixedly connected to the fixed plate, and an air pump is fixedly connected to the bottom end of the fixed plate. A folding cover is fixedly connected to the upper end of the fixed plate, and the upper end of the folding cover is fixedly connected to the bottom end of the first rotating plate. An air pump is fixedly connected to one side. The air pump creates a negative pressure state between the fixed plate and the first rotating plate, so that when the receiving holes are unfolded, the first rotating plate can provide stable adsorption of the compression-molded pulp during rotation.

[0010] As a preferred technical solution of this utility model, the pressure plate is fixedly connected to an industrial camera inside the back-shaped cutter. The industrial camera corresponds to the back-shaped cutter groove. By setting the industrial camera, monitoring is provided to prevent the pulp molding from shifting during rotation.

[0011] As a preferred technical solution of this utility model, a multi-axis robotic arm is provided on one side of the back-shaped groove. The multi-axis robotic arm is fixedly connected to one side of the base plate, and a push plate is fixedly connected to the end of the multi-axis robotic arm. By providing a multi-axis robotic arm and a push plate on one side of the base plate, it can be rotated to the second rotating plate to adjust the position of the pulp molding.

[0012] This utility model has the following advantages:

[0013] (1) By integrating pulp molding with the edge trimming mechanism, random die cutting can be performed after molding, thereby shortening the time from pulp molding to edge trimming and improving the overall edge trimming efficiency.

[0014] (2) First, the forward and reverse motors drive the screw to rotate and move the transfer plate down, causing the pressure frame to close with the mold groove on the first rotating plate, so that the pulp molding is subjected to force and formed. Then, the first rotating plate rotates until the mold groove and the receiving groove close, and the pulp molding is transferred to the receiving mold. Then, the electric telescopic rod extends to press down the pressure plate and the return cutter to perform the trimming operation. Then, the second rotating plate rotates to remove the pulp molding after trimming, forming a process from molding to trimming, which improves the batch processing efficiency of pulp molding.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please refer to the following: Figure 1-4 The illustrated pulp molding and trimming machine includes a base plate 1, a support frame, and a top plate 2. A forward and reverse motor is fixedly connected to the upper end of the top plate 2. When the forward and reverse motors are activated, the screw 3 rotates, causing the pressure frame 5 and the mold inside the pressure frame 5 to move down and close with the mold slot 8 on the first rotating plate 7. Then, a feeding mechanism feeds the material from the mold slot 8. Figure 1The feed hole on the right side of the pressure frame 5 is used for feeding. The output shaft of the positive and negative motors is fixedly connected to a screw 3. A moving plate 4 is threadedly connected to the bottom side of the screw 3. A pressure frame 5 is fixedly connected to one side of the bottom of the moving plate 4. The height of the pressure frame 5 is greater than the distance from the moving plate 4 to the bottom of the return cutter 13 when the electric telescopic rod 11 is fully retracted. A pressure mold is fixedly connected to the bottom of the pressure frame 5 by bolts. A first receiving seat 6 is provided on the bottom side of the pressure mold, and the first receiving seat 6 is higher than the second receiving seat 14. The upper end of the first receiving seat 6 contacts a first rotating plate 7. The upper end of the first rotating plate 7 has an opening. Mold groove 8 is bolted to a fixed mold. A base plate 1 is fixedly connected to a first connecting plate 9 on one side of the first receiving seat 6. A first motor is fixedly connected to one of the first connecting plates 9. The first motor drives a first rotating rod 10 to rotate, causing the first rotating plate 7 to rotate and causing the receiving mold on the second receiving seat 14 of the mold groove 8 to close. The receiving mold has the same structure as the compression mold, enabling the transfer of the compression-molded receiving mold. The output end of the first motor is fixedly connected to the first rotating rod 10, with two sides of the first rotating rod 10... A first connecting column is fixedly connected to one end of the first rotating plate 7. An electric telescopic rod 11 is fixedly connected to the other side of the bottom of the sliding plate 4. A pressure plate 12 is fixedly connected to the bottom of the electric telescopic rod 11. A circular cutter 13 is fixedly connected to the bottom of the pressure plate 12 by bolts. A second receiving seat 14 is fixedly connected to the bottom side of the pressure plate 12 on the base plate 1. A second connecting plate 15 is provided on one side of the second receiving seat 14. A second motor is fixedly connected to the second connecting plate 15. When the second motor is started, the second rotating rod 16 can rotate. Then the second rotating plate 17 rotates, causing the pulp mold cut by the back-shaped cutter 13 to rotate and flip out, thereby improving the efficiency of batch processing, shortening the processing time, and improving the overall edge cutting efficiency. The output end of the second motor is fixedly connected to the second rotating rod 16. The second connecting column is fixedly connected to both sides of the second rotating rod 16. The second rotating plate 17 is fixedly connected to one side of the second connecting column. The receiving mold is fixedly connected to the second rotating plate 17 by bolts. The receiving mold has a back-shaped cutting groove 18, which corresponds to the back-shaped cutter 13.

[0022] Among them, the upper end of the first rotating plate 7 is fixedly connected with four pads 19. The pads 19 are made of rubber material and are located on the outside of the fixed mold. By setting the pad structure, the first rotating plate 7 can contact the second rotating plate 17 after it is flipped, and provide contact buffer to reduce collision wear.

[0023] The mold has four receiving holes 20, each containing a stop plate 21. A fixing plate 22 is fixedly connected to the bottom of each stop plate 21. An electric push rod 23 is fixedly connected to the top of the fixing plate 22, with its bottom fixedly connected to the fixing plate 22. A vacuum pump 24 is fixedly connected to the bottom of the fixing plate 22. A folding cover is fixedly connected to the top of the fixing plate 22, and its top is fixedly connected to the bottom of the first rotating plate 7. A vacuum pump 24 is fixedly connected to one side. The retraction of the electric push rod 23 allows... The fixed plate 22 moves closer to the first rotating plate 7, and then the abutment plate 21 moves up to be flush with the upper end of the receiving hole 20, thereby providing a normal pulp molding process. When the first rotating plate 7 flips, the vacuum pump 24 can be activated to provide negative pressure traction. With the cooperation of the folding cover, the first rotating plate 7 and the fixed plate 22 are in a negative pressure state, and then the receiving hole 20 provides airflow traction. At this time, the first rotating plate 7 rotates, which can provide traction for the pulp molding when the rotation angle is greater than 90 degrees, ensuring that the pulp molding falls stably onto the receiving mold.

[0024] The pressure plate 12 is fixedly connected to the inner side of the back-shaped cutter 13 with an industrial camera 25. The industrial camera 25 corresponds to the back-shaped cutter 18. The industrial camera 25 is fixedly connected to the multi-axis robotic arm 26 through wires. The industrial camera 25 provides monitoring of the pulp molding placed on the second rotating plate 17, so as to facilitate manual or mechanical adjustment.

[0025] Among them, a multi-axis robotic arm 26 is provided on one side of the back-shaped groove 18. The multi-axis robotic arm 26 is fixedly connected to one side of the base plate 1. A push plate 27 is fixedly connected to the end of the multi-axis robotic arm 26. The multi-axis robotic arm 26 transmits the signal fed back by the industrial camera 25 to the multi-axis robotic arm 26, and then uses the push plate 27 to push the pulp mold placed on the receiving mold to move to the appropriate position.

[0026] Working principle: First, the forward and reverse motors are started, causing the screw 3 to rotate. Then, the moving plate 4 moves down, at which point the mold on the bottom side of the pressure frame 5 closes with the mold groove 8 on the first rotating plate 7. Then, the external injection mechanism... Figure 1The material is fed into the mold groove and between the mold and the die through the through hole on the right side of the medium pressure frame 5. The pressure provided by the die completes the molding of the pulp. Further, the screw 3 reverses and causes the transfer plate 4 to move up to a certain position. Then, the first motor on the first connecting plate 9 can be started, causing the first rotating plate 7 to rotate. At this time, the electric push rod 23 extends, causing the abutment plate 21 to move down, the receiving hole 20 opens, and the vacuum pump 24 draws out the negative pressure between the fixed plate 22 and the first rotating plate 7, so that the first rotating plate 7 and the pulp mold rotate together, and the pulp mold is transferred to the second rotating plate 17. The pad 19 on the first rotating plate 7 abuts against the second rotating plate 17. When the second rotating plate 17 is at its top, the vacuum pump 24 stops operating and transfers the pulp molded material to the second rotating plate 17. Then, the first motor reverses, and the first rotating plate 7 no longer contacts the second rotating plate 17. At this time, the electric telescopic rod 11 extends, the pressure plate 12 and the back-shaped cutter 13 move down and press against the back-shaped cutting groove 18, thereby completing the cutting. During this process, the industrial camera 25 provides monitoring. In some cases, the position of the pulp molded material can be adjusted by the multi-axis robotic arm 26 and the push plate 27. After the cutting is completed, the second motor drives the second rotating plate 17 to rotate counterclockwise, thereby causing the cut pulp molded material to detach and completing the unloading.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
