Description

Technical Field

[0001] This invention belongs to the field of molding technology, specifically relating to a mechanical operation method for pulp molding. Background Technology

[0002] In the past, "molding" was often used to refer to a type of plastic molding process, which involves shaping plastic materials under pressure (usually with simultaneous heating) using a mold or die. Here, "mold" is used to modify "plastic".

[0003] A search revealed that patent application number 20231672322.X, published on July 14, 2023, discloses a pulp fiber separation device with a circulating stirring function. Specifically, it discloses a device comprising: a first fixed frame, a rotating ring rotatably connected to the first fixed frame, a first motor mounted on the first fixed frame, a second fixed cylinder fixedly connected to the rotating ring, a connecting plate on the second fixed cylinder, a second fixed frame located inside the first fixed frame, and a rotating tube rotatably connected to the first fixed frame, with a fixed ring plate fixedly connected to the rotating tube.

[0004] Both the moving tube and the fixed ring plate are fixedly connected to circumferentially equidistantly distributed stirring plates. This structure, through the counter-rotation of the second fixed cylinder and the rotating tube, combined with the U-shaped arrangement of the stirring plates, causes the U-shaped concave surface of the stirring plates to obstruct and disrupt the mixture during counter-clockwise rotation. During clockwise rotation, the stirring plates guide the mixture obliquely towards the center of the device, accelerating the mixing process. After mixing, the pulp in this structure is discharged from the outlet and molded onto a mold. However, it does not consider the separation of the molded pulp from the mold after molding. In existing technologies, due to the short molding time during pulp molding production, the pulp molds are prone to internal deformation and adhesion during removal and stacking, leading to jamming within the equipment during production and affecting subsequent processes and molding during batch processing. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanical operation method for pulp molding, which solves the problem in the prior art that, due to the short molding time during pulp molding production, the pulp mold is prone to internal deformation and adhesion when being removed and packaged, resulting in it getting stuck in the equipment during production and making separation difficult.

[0006] To achieve the above objectives, the present invention provides a method for operating the pulp molding machine, wherein the pulp molding machine includes a chassis, a support frame, a hook frame, a rotating base, a first motor, a fourth motor, and a filter cylinder. The support frame, the first motor, and the fourth motor are fixedly mounted on the chassis. A nozzle is fixedly connected to the lower end of the support frame, and the lower end of the nozzle has two or more spray heads. One end of the hook frame is fixedly connected to the output end of the fourth motor, and the other end of the hook frame is fixedly connected to a first cylinder. A vacuum suction cup is fixedly connected to one end of the first cylinder, and the suction cup of the vacuum suction cup cooperates with a pulp injection box on the turntable. The output end of the first motor is fixedly connected to the rotating base, and the upper end of the rotating base is fixedly connected to... The system has two second motors, each with a turntable rotatably connected to its output end. Two or more pulp injection molding boxes are fixedly connected to the upper ends of each turntable. One or more support rods are fixedly connected to one side of the turntables on the base. One or more support rods are fixedly connected to the lower end of the filter cylinder. Two or more first solenoid valves are fixedly connected to the upper end of the filter cylinder. A filter tank is rotatably connected to the lower end of each of the two or more first solenoid valves. A collection cylinder is fixedly connected to the upper end of the two or more first solenoid valves. A third motor is fixedly connected to the lower end of the collection cylinder. An agitator is fixedly connected to the output end of the third motor. The lower end of the filter tank communicates with the filter cylinder, and a second solenoid valve is fixedly connected to the lower end of the filter cylinder.

[0007] The method includes the following steps:

[0008] S1. First, introduce the pulp material and water into the feed cylinder, then run the third motor to drive the agitator to stir the pulp material and water to make it into pulp. Then run the first solenoid valve to filter the pulp through the filter tube into the filter cylinder for preparation. Then run the second solenoid valve to discharge the pulp.

[0009] S2. Start the first motor and drive the rotating seat so that a pulp injection box on the rotating seat is located below the second solenoid valve. Move the second solenoid valve to discharge the pulp. When a pulp injection box is full, the second motor rotates to drive the rotating seat to rotate so that another pulp injection box on the rotating seat rotates to the bottom of the second solenoid valve for injection. Continue until all pulp injection boxes on the rotating seat are full and then set.

[0010] S3. After the pulp is injected, a water-soluble lubricant can be sprayed onto the surface of the pulp through a nozzle, and a rotating seat driven by the first motor can be rotated to the bottom of the vacuum suction cup. The first cylinder drives the vacuum suction cup to suck out the molded part, and the fourth motor is rotated to export the molded part.

[0011] The above setup involves rotating the agitator inside the collection cylinder to evenly mix the pulp material with water. The first solenoid valve is then opened, allowing the mixed material to enter the filter cylinder for initial filtration. The second solenoid valve is then opened to control the pulp output in stages, facilitating batch molding. After the pulp has solidified in the pulp injection box, a water-soluble lubricant can be sprayed onto the pulp mold through a nozzle. When the vacuum suction cup removes the pulp mold, it is less likely to stick to the equipment, thus minimizing the impact on subsequent processes and molding effects during batch processing. Furthermore, the vacuum suction cup allows the molded material to be removed by releasing it, facilitating packaging.

[0012] Furthermore, the first solenoid valve is connected to the filter tank via threads, and the upper end of the filter cylinder is provided with a corresponding mounting hole for the filter tank. The first solenoid valve and the filter tank are engaged with the mounting hole.

[0013] The above settings are achieved by connecting the first solenoid valve to the filter tank via a threaded connection, which facilitates the disassembly of the first solenoid valve and the filter tank. After connection, the filter tank and the first solenoid valve are snapped into the mounting hole to ensure the installation of the filter tank and the first solenoid valve.

[0014] Furthermore, a guide cylinder is fixedly connected to the upper end of the collecting cylinder, a feed cylinder is fixedly connected to the upper end of the guide cylinder, and a metering device is fixedly connected to the circumferential surface of the collecting cylinder.

[0015] The above setup allows for easy diversion of pulp material and water from the feed cylinder into the collection cylinder via a guide tube, while a metering device facilitates observation of the pulp mixing volume within the collection cylinder.

[0016] Furthermore, a mounting block is fixedly connected to the circumferential surface of the collection cylinder, and a sliding groove is provided on one side end of the mounting block. A sampling tube is slidably connected to the inner circumferential wall of the sliding groove.

[0017] The above setup allows for easy checking of the pulp-to-water ratio by pulling the sampling tube, thus ensuring the reliability of the molding process.

[0018] Furthermore, a support plate is fixedly connected to one side of the support frame, and a positioning hole is opened at the upper end of the support plate. A nozzle is fixedly connected to the positioning hole. In step S3, after the pulp is injected, water-soluble lubricant is sprayed onto another pulp injection box through the nozzle connected to an external water-soluble lubricant.

[0019] The above settings can increase the spraying efficiency of water-soluble lubricants by adding nozzles.

[0020] Furthermore, a fixed frame is fixedly connected to one side of the support frame, and a monitoring device is fixedly connected to one side of the fixed frame.

[0021] The above settings allow monitoring equipment to monitor the spraying of water-soluble lubricant from the nozzles.

[0022] Furthermore, a sliding rotating bar is fixedly connected to the lower end of the rotating seat, and an arc-shaped rotating seat is fixedly connected to the lower end of the rotating seat. The sliding rotating bar is slidably connected inside the arc-shaped rotating seat. In step S2, the first motor is started to drive the rotating seat to rotate on the arc-shaped rotating seat.

[0023] The above settings, by setting an arc-shaped rotating seat and having the arc-shaped rotating bar rotate within the arc-shaped rotating seat, ensure that the rotating seat can rotate more reliably on the arc-shaped rotating seat.

[0024] Furthermore, the distance between the end of the support frame fixed to the chassis and the center of one turntable is greater than the distance from the center of one turntable to the outermost edge of another turntable.

[0025] The above settings ensure that the turntable is not obstructed by the support frame when it rotates. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] Example 1

[0037] Please see Figures 1-8This invention provides a method for operating a pulp molding machine. The pulp molding machine includes a chassis 1, a support frame 202, a hook frame 205, a rotating seat 208, a first motor 209, a fourth motor 211, and a filter cylinder 301. The support frame 202, the first motor 209, and the fourth motor 211 are fixed on the chassis 1. A nozzle 206 is fixedly connected to the lower end of the support frame 202. The lower end of the nozzle 206 has two or more spray heads. In this embodiment, the spray heads have ten... Two hooks, one end of which is fixedly connected to the output end of the fourth motor 211, and the other end of which is fixedly connected to the first cylinder 204. One end of the first cylinder 204 is fixedly connected to a vacuum suction cup 201, which engages with the pulp injection molding box 207 on the turntable 203. The rotating seat 208 is fixedly connected to the output end of the first motor 209, and two second motors 210 are fixedly connected to the upper end of the rotating seat 208. The outputs of the two second motors 210... The base plate 1 is rotatably connected to a turntable 203. Two or more pulp injection molding boxes 207 are fixedly connected to the upper ends of both turntables 203. In this embodiment, there are four pulp injection molding boxes 207, evenly arranged along the circumference of a turntable. One or more support rods 13 are fixedly connected to the upper end of the base plate 1. In this embodiment, there are four support rods 13, fixedly connected to the lower end of the filter cylinder 301. Two or more first solenoid valves 305 are fixedly connected to the upper end of the filter cylinder 301. A filter tank 306 is rotatably connected to the lower end of each of the two or more first solenoid valves 305. A collection cylinder 302 is fixedly connected to the upper end of the two or more first solenoid valves 305. A third motor 304 is fixedly connected to the lower end of the collection cylinder 302. A stirring fan 303 is fixedly connected to the output end of the third motor 304. The lower end of the filter tank communicates with the filter cylinder. A second solenoid valve 307 is fixedly connected to the lower end of the filter cylinder. The pulp molding machinery operation engine method includes the following steps:

[0038] S1. First, the pulp material and water are introduced into the feed cylinder 10. Then, the third motor 304 drives the agitator 303 to stir the pulp material and water to make it into pulp. Then, the first solenoid valve 305 is run to filter the pulp through the filter tank 306 into the filter cylinder 301 for preparation. Then, the pulp is discharged by running the second solenoid valve 307.

[0039] S2. Start the first motor 209 and drive the rotating seat 208 to rotate so that a pulp injection box 207 on the rotating seat 208 is located below the second solenoid valve 307. Move the second solenoid valve 307 to discharge the pulp. When the pulp injection box 207 is full, the second motor 210 rotates to drive the rotating seat 208 to rotate so that another pulp injection box 207 on the rotating seat 208 rotates to be below the second solenoid valve 307 for filling. Continue until all the pulp injection boxes on the rotating seat 208 are full.

[0040] S3. After the pulp is injected, a water-soluble lubricant can be sprayed onto the surface of the pulp through the nozzle 206, and a rotating seat 208 can be driven by the first motor 209 to rotate below the vacuum suction cup 201. The first cylinder 204 drives the vacuum suction cup 201 to suck out the molded part, and the fourth motor 211 is rotated to export the molded part.

[0041] like Figure 2 and Figure 3 The nozzle 206 is matched with eight pulp injection boxes 207, and the four first solenoid valves 305 are respectively fixedly connected to the four filter tanks 306 by threads.

[0042] The nozzle 206, in conjunction with the pulp injection molding box 207, houses a water-soluble lubricant storage device within the support frame. This storage device is connected to the nozzle via a switch; opening and closing the switch allows the nozzle to spray the water-soluble lubricant evenly onto the molded pulp surface. Four filter canisters 306 are threadedly fixed to the first solenoid valve 305, facilitating easy removal of the filter canisters 306. Each filter canister 306 has a filter screen at its inlet for filtration. The first solenoid valve 305 is threadedly connected to each filter canister 306. The upper end of the filter cylinder 301 has corresponding mounting holes 3011. The first solenoid valve 305 engages with the filter canister 306 through these mounting holes. To ensure a tight seal, a sealing ring is placed between the mounting hole 3011, the filter canister 3011, and the first solenoid valve 305.

[0043] like Figure 2 The upper end of the collecting cylinder 302 is fixedly connected to the guide cylinder 9, the upper end of the guide cylinder 9 is fixedly connected to the feed cylinder 10, and the circumferential surface of the collecting cylinder 302 is fixedly connected to the metering device 7.

[0044] The guide tube 9 installed on the collection tube 302 reduces material and water splashing. The meter 7 installed on the surface of the collection tube 302 displays the pulp height inside the collection tube 302, making it easy to determine whether there is too much or too little material and water.

[0045] like Figure 2 An installation block 8 is fixedly connected to the circumferential surface of the collection cylinder 302. A sliding groove 12 is provided on one side of the installation block 8. A sampling tube 11 is slidably connected to the inner circumferential wall of the sliding groove 12. A sealing ring is provided between the sampling tube 11 and the installation block 8 to ensure the sealing of the sampling tube 11 after it is installed into the sliding groove 12.

[0046] The mounting block 8, which is set on the surface of the collection cylinder 302, serves to connect with the sampling tube 11. The sampling tube 11, which is set in the mounting block 8, serves to sample and inspect the processed pulp to ensure that the pulp ratio meets the injection molding conditions.

[0047] like Figure 2 As shown, a support plate 6 is fixedly connected to one side of the support frame 202. A positioning hole 15 is provided at the upper end of the support plate 6. A nozzle 14 is fixedly connected inside the positioning hole 15. The nozzle 14 is connected to an external water-soluble lubricant storage device to realize the spraying of water-soluble lubricant.

[0048] The abutment plate 6 on one side of the support frame 202 serves to fix the nozzle 14, so that the nozzle 14 acts inside the pulp injection box 207. The nozzle 14 on the abutment plate 6 can introduce water-soluble lubricating oil into the pulp mold, so that the pulp mold is less likely to stick when it is removed.

[0049] like Figure 2 A fixed frame 5 is fixedly connected to one side of the support frame 202, and a monitoring device 16 is fixedly connected to one side of the fixed frame 5. The monitoring device 16 can be a camera or other equipment.

[0050] The fixing frame 5 installed on one side of the support frame 202 serves to fix the fixing frame 5 in place, and the monitoring device 16 installed on one side of the fixing frame 5 serves to monitor the operation and processing status of the equipment.

[0051] like Figure 6 and Figure 7 As shown, a sliding rotating bar 18 is fixedly connected to the lower end of the rotating seat 208, and an arc-shaped rotating seat 17 is fixedly connected to the lower end of the rotating seat 208. The sliding rotating bar 18 is slidably connected to the arc-shaped rotating seat 17.

[0052] The arc-shaped rotating seat 17 set under the rotating seat 208 slides on the surface of the sliding bar 18, thereby increasing the stability of the rotating seat 208 and making it less prone to deviation. When the rotating seat 208 drives the sliding bar 18 to rotate, it can limit the movement of its body.

[0053] In a specific embodiment of the present invention, the support rod 13 mounted on the chassis 1 provides stable support for the filter cylinder 301, ensuring that the outlet of the second solenoid valve 307 is higher than the turntable 203, thus facilitating the introduction of pulp into the pulp injection box 207. The filter tank 306 mounted inside the filter cylinder 301 filters out pulp residues, enhancing aesthetics and sieving large pieces of material during molding. The first solenoid valve 305 mounted on the filter cylinder 301 controls the pulp discharge rate in the collection cylinder 302. The guide cylinder 9 mounted on the collection cylinder 302 reduces material and water splashing. The metering device 7 mounted on the surface of the collection cylinder 302 displays the pulp level, facilitating the determination of excessive or insufficient material and water. The mounting on the surface of the collection cylinder 302... Block 8 serves to connect to the sampling tube 11. The sampling tube 11, located within Block 8, allows for the sampling and inspection of the processed pulp, ensuring that the pulp ratio meets the injection molding requirements. The vacuum suction cup 201, located under the support frame 202, can extract the pulp from the pulp injection box 207, facilitating its collection and packaging. The nozzle 206, located under the support frame 202, introduces water-soluble lubricant into the pulp mold, preventing sticking when the vacuum suction cup 201 removes the pulp mold. The first motor 209 drives the rotating seat 208 to rotate, increasing production efficiency when changing the pulp injection box 207. The arc-shaped rotating seat 17, located under the rotating seat 208, slides on the surface of the sliding strip 18, increasing the stability of the rotating seat 208 and preventing it from shifting.

[0054] The working principle and usage process of this invention are as follows: First, the pulp material is introduced into the feed cylinder 10 along with hot water. Then, the third motor 304 drives the agitator 303 to stir the pulp material and water, making it into pulp. Next, the first solenoid valve 305 is run to filter the pulp through the filter tank 306 into the filter cylinder 301 for preparation. Then, the second solenoid valve 307 is run to discharge the pulp in stages. One of the vacuum suction cups 201 can drive one of the turntables 203 to rotate, so that the four pulp injection boxes 207 are evenly coated. After the pulp is received and shaped, once one set of pulp injection molding boxes 207 has formed a mold, the first motor 209 can be run to drive another turntable 203 to align with its second solenoid valve 307. After the pulp is injected, water-soluble lubricant can be sprayed onto the surface of the pulp through the nozzle 206. The first cylinder 204 drives the vacuum suction cup 201 to suck out the mold. When the vacuum suction cup 201 sucks out the pulp mold, it is not easy for the pulp mold to stick to the equipment, so that it is not easy to affect the next process and the molding during batch processing.

[0055] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
