Description

Technical Field

[0001] The present invention application relates to the technical field of shaping devices, and specifically to a PPH plastic storage tank production and shaping device and its usage method. Background Art

[0002] PPH plastic storage tanks are thermoplastic plastic products polymerized from propylene monomers, which can store and react with most inorganic acid, alkali, and salt solutions and most organic solvents. They are ideal storage containers for storing and reacting chemical corrosion solutions and clean solutions. When producing plastic storage tanks, processes such as mold core winding, injection molding, rotational molding, and blow molding are generally used. Among them, mold core winding is to process PPH pellet materials into a tank body by using a PPH spiral extrusion winding unit. The storage tanks produced by the winding technology have high strength, are suitable for various storage environments, and can withstand high pressure and load.

[0003] When the current plastic storage tank production and shaping device is in use, after heating the mold barrel with a torch head, the PPH pellet materials are extruded and wound around the mold barrel and wait for cooling and shaping. Since the existing shaping device itself does not have a cooling structure, after winding, even if it is extruded and shaped by a brush roller, it is easy to cause uneven thickness distribution of the tank body under the action of gravity due to untimely cooling, affecting the shaping effect. At the same time, since the bottom of the mold barrel needs to be supported by a support roller when the mold barrel rotates, after the plastic storage tank is wound and shaped, it cannot be directly removed from the mold barrel, and it is necessary to separate the mold barrel from the support roller by lifting the mold barrel and other means, resulting in a more complex structure and more cumbersome and laborious operation of the shaping device. Summary of the Invention

[0015] Further, a usage method of a PPH plastic storage tank production and shaping device, the usage method includes the following steps:

[0016] Step (A), PPH granular materials are extruded and wound around the mold barrel and are extruded into shape;

[0017] In step (A1), during shaping, first select the corresponding brush roller according to the thickness of the storage tank and the requirements of the outer surface texture. Connect the corresponding brush roller to the two rotating plates by bolts for rotation. Turn on Servo Motor 1. The operation of Servo Motor 1 drives the rotating plates to rotate, and the rotation of the rotating plates adjusts the position of the brush roller. Select the corresponding brush roller to approach the mold barrel according to the thickness of the local part of the plastic storage tank and the outer surface texture. When adjustment is needed, Servo Motor 1 runs again to drive another corresponding brush roller to approach the mold barrel;

[0018] In step (A2), turn on Servo Motor 3. The operation of Servo Motor 3 drives the drive pipe to rotate. The drive pipe drives the mold barrel to rotate through the fixed sleeve block and the fixed insertion rod. The mold barrel drives the fixed pipe to rotate, so that the drive pipe and the fixed pipe rotate on the support roller, and at the same time drives the mold barrel to rotate;

[0019] In step (A3), then turn on the torch head and the glue gun extrusion head. The torch head sprays flames to bake and heat the mold barrel. After heating, the glue gun extrusion head immediately extrudes the PPH granular material and winds it around the heated mold barrel. At the same time, the brush roller extrudes and shapes the material wound on the outer surface of the mold barrel. During winding, Servo Motor 2 runs to drive the lead screw to rotate. The lead screw drives the moving seat to slide on the limit slide bar, which can drive the torch head and the glue gun extrusion head to move, so that the glue gun extrusion head can wind and shape on the mold barrel;

[0020] In step (B), cool the tank body while winding;

[0021] In step (B1), when the mold barrel rotates, it drives the teeth to rotate. The rotation of the teeth drives the meshing gear 2 to rotate. When gear 2 rotates, it drives the meshing connected gear 1 to rotate rapidly. When gear 1 rotates, it drives the fan blade to rotate. When the fan blade rotates, it inhales the external air flow into the fixed pipe and blows it into the mold barrel;

[0022] In step (B2), it flows along the inner wall of the mold barrel under the guidance of the air guide cover, quickly taking away the heat of the wound and formed tank body on the outer surface of the mold barrel. At the same time, the air flow continues to flow inside the mold barrel towards the drive pipe side, and the high-temperature air flow after heat exchange preheats the un-wound mold barrel to be heated;

[0023] In step (C), cutting;

[0024] In step (C1), after winding and forming, turn off the torch head and the glue gun extrusion head. Servo Motor 1 continues to run to drive the mold barrel to rotate, so that the fan blade continues to run to cool the tank body;

[0025] In step (C2), when the two ends of the tank body need to be cut, Servo Motor 2 runs to drive the moving seat to move, thereby driving the cutting support plate to the cutting point. When reaching the cutting point, the electric push rod runs to drive the cutting blade to move down to cut the tank body;

[0026] Step (C3): During cutting, the die barrel is still rotating, so that the cutting blade can perform circumferential cutting on the tank body, and both ends of the tank body can be cut flat. After cutting is completed, the electric push rod operates to drive the cutting blade to move upward, and the second servo motor operates to drive the torch head, glue gun extrusion head, and brush roller to move to the side of the fixed pipe;

[0027] Step (D): Remove the tank body from the die barrel;

[0028] Step (D1): Loosen the bolts on the fixed clamping plate to release the fixation between the fixed clamping plate and the limit rotating plate. Rotate the limit rotating plate so that the limit rotating plate separates from the fixed clamping plate. At this time, the limit of the limit rotating plate on the rotating bracket is released. Pull the moving bracket to drive the sliding plate to slide inside the support chassis until the fixed sleeve block separates from the fixed insertion rod;

[0029] Step (D2): After the fixed sleeve block separates from the fixed insertion rod, the limit of the die barrel on the drive pipe is released. Rotate the rotating bracket to drive the drive pipe, rotating bracket, third servo motor, and support roller to rotate to the side of the die barrel, so that the limit on the outer surface of one end of the die barrel close to the drive pipe is released;

[0030] Step (D3): After the support of the drive pipe for the die barrel is released, the pulling sleeve block provides a pulling force to the die barrel and the fixed pipe, so that the die barrel can remain horizontal. Push the tank body on the outer surface of the die barrel to remove the tank body from the die barrel along the drive pipe;

[0031] Step (D4): After the tank body is removed, rotate the drive pipe in the reverse direction to make the rotating bracket rotate to fit with the moving bracket. Push the rotating bracket and the moving bracket to insert the fixed insertion rod back into the fixed sleeve block, and then rotate the limit rotating plate so that the limit rotating plate is clamped inside the fixed clamping plate and fixed with bolts.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. In the present invention, when the die barrel rotates and winds, it drives the fan blades to rotate to cool the inner wall of the die barrel. After the PPH granular material is extruded and wound on the die barrel and formed by extrusion through the brush roller, it can be quickly shaped, solving the problem of untimely shaping and cooling of the existing PPH plastic storage tank production and shaping device during use. Thereby, it avoids untimely shaping of the tank body caused by untimely cooling and improves the shaping accuracy of the shaping device during use.

[0034] 2. After the plastic storage tank is wound and formed and cooled, the driving pipe and the supporting roller can be moved to the side of the mold barrel by pulling and rotating the driving pipe and the supporting roller, so that the limit at one end of the mold barrel is released, and the formed plastic storage tank can be removed. The structure is simple, which solves the problem that the existing PPH plastic storage tank production and shaping device is inconvenient to separate the tank body from the mold barrel after shaping, and improves the operation convenience of the shaping device during use.

[0035] 3. During the winding and forming process, the cutting blade that moves synchronously with the burner head cuts the tank body after cooling and shaping, making both ends of the tank body flat, which is convenient for subsequent internal and external welding operations of the plastic storage tank, and avoids the problem that the two ports are not flush enough to affect subsequent welding when the tank body is formed by inclined winding.

[0036] 4. In the present invention, through the adjustable rotating plate, after the PPH granular material is extruded and wound on the mold barrel, the position of the brush roller is adjusted by driving the rotating plate to rotate, so as to control different brush rollers to extrude and form the extruded material, thereby facilitating the control of the thickness of the tank body and the surface pattern of the tank body during the shaping of the plastic storage tank, and improving the application range of the shaping device.

[0037] 5. During the shaping and cooling, through the air guide cover on the side of the fan blade, the air flow can flow along the inner wall of the mold barrel, thus facilitating the cooling of the inner wall of the mold barrel. The heat-exchanged air flow continues to flow towards the mold barrel to be wound, and can preheat the mold barrel body to be wound.

[0038] 6. In the present invention, after the driving pipe and the supporting roller are moved to the side of the mold barrel, the mold barrel is pulled by the pulling sleeve block and the pulling support bracket, so that after the support of the driving pipe and the supporting roller on one end of the mold barrel is released, the mold barrel can still remain horizontal, ensuring the stability of the shaping device during use.

Both sliding plates 27 are arranged in a horizontal T shape, and a T-shaped sliding groove matching the sliding plate 27 is formed inside the support chassis 1. The length of the sliding groove is greater than the length of the fixed sleeve block 24.

[0053] After the driving pipe 3 moves and separates from the mold barrel 2, in order to pull and support the mold barrel 2, a fixed ring plate 31 is fixed at one end of the fixed pipe 4 away from the mold barrel 2. The outer diameter of the fixed ring plate 31 is greater than the outer diameter of the fixed pipe 4, and the inner diameter of the fixed ring plate 31 is smaller than the inner diameter of the fixed pipe 4.

A support plate 8 is fixed on the side of the fixed rod 7 facing the mold barrel 2. A number of blowtorch heads 9 are equidistantly fixed on the support plate 8. The outlet of each blowtorch head 9 faces the mold barrel 2. A number of rotatable brush rollers 14 are arranged inside the support frame 6 below the glue gun extrusion head 10.

[0055] After the shaping is completed, in order to avoid uneven ports at both ends of the can body, the support plate 8 is set to an arc shape that cooperates with the mold barrel 2. A cutting support plate 19 is fixed on the top of the support plate 8. An electric push rod 20 is set on the top of the cutting support plate 19. The output end of the electric push rod 20 slides through the cutting support plate 19 and a cutting blade 21 is fixed thereon. The cutting blade 21 is parallel to the port of the mold barrel 2 and is used to cut the port of the can body after shaping.

[0056] As a further optimization solution, Figure 4 and Figure 5 As shown, fixed plates 11 are symmetrically fixed on the side walls of the support frame 6 below the glue gun extruder head 10, and rotating plates 12 are arranged on opposite sides of the two fixed plates 11. The two rotating plates 12 are rotatably connected to the side walls of the fixed plates 11, and a number of brush rollers 14 are rotatably connected between the two rotating plates 12 by bolts at equal intervals. A servo motor 13 is installed on the outer side of one of the fixed plates 11, and the output end of the servo motor 13 rotates through the fixed plate 11 and is fixed on the rotating plate 12.

[0057] Working principle: When shaping, first select the corresponding brush roller 14 according to the thickness of the storage tank and the outer surface texture, and connect the corresponding brush roller 14 between the two rotating plates 12 by bolts, turn on the servo motor 13, and the servo motor 13 drives the rotating plate 12 to rotate, and the rotating plate 12 rotates to adjust the position of the brush roller 14, and select the corresponding brush roller 14 close to the mold barrel 2 according to the local thickness and outer surface texture of the plastic storage tank. When adjustment is needed, the servo motor 13 runs again to drive another corresponding brush roller 14 close to the mold barrel 2, turn on the servo motor 3 23, and the servo motor 3 23 runs to drive the drive tube 3 to rotate, and the drive tube 3 drives the mold barrel 2 to rotate through the fixed sleeve block 24 and the fixed plug rod 25, and the mold The barrel 2 drives the fixed tube 4 to rotate, so that the driving tube 3 and the fixed tube 4 rotate on the supporting roller 35, and at the same time drives the mold barrel 2 to rotate, and then the ignition gun head 9 and the glue gun extrusion head 10 are opened, and the ignition gun head 9 sprays flames to bake and heat the mold barrel 2. After heating, the glue gun extrusion head 10 immediately extrude the PPH granular material and wind it on the heated mold barrel 2, and at the same time, the brush roller 14 extrude and mold the material wound on the outer surface of the mold barrel 2. During winding, the servo motor 18 drives the screw rod 15 to rotate, and the screw rod 15 drives the moving seat 5 to slide on the limit slide rod 17, which can drive the ignition gun head 9 and the glue gun extrusion head 10 to move, so that the glue gun extrusion head 10 can be wound on the mold barrel 2.

[0058] While winding, the tank body is cooled. When the die barrel 2 rotates, it drives the tooth 41 to rotate. The rotation of the tooth 41 drives the second gear 40 meshed with it to rotate. When the second gear 40 rotates, it drives the first gear 38 meshed and connected with it to rotate rapidly. When the first gear 38 rotates, it drives the fan blade 37 to rotate. When the fan blade 37 rotates, it sucks the external air flow into the fixed pipe 4 and blows it into the die barrel 2. Under the guidance of the air guide cover 42, it flows along the inner wall of the die barrel 2, quickly taking away the heat of the wound and formed tank body on the outer surface of the die barrel 2. At the same time, the air flow continues to flow towards the driving pipe 3 inside the die barrel 2, and the high-temperature air flow after heat exchange preheats the un-wound die barrel 2 to be heated.

[0059] After winding and forming, the torch head 9 and the glue gun extrusion head 10 are closed, and the first servo motor 13 continues to operate to drive the die barrel 2 to rotate, so that the fan blade 37 continues to operate to continue cooling the tank body. When the two ends of the tank body need to be cut, the second servo motor 18 operates to drive the moving seat 5 to move, thereby driving the cutting support plate 19 to the cutting point. When reaching the cutting point, the electric push rod 20 operates to drive the cutting blade 21 to move downward to cut the tank body. During cutting, the die barrel 2 is still rotating, so that the cutting blade 21 can cut the tank body in a circular manner, and the two ends of the tank body can be cut flat. After cutting, the electric push rod 20 operates to drive the cutting blade 21 to move upward, and the second servo motor 18 operates to drive the torch head 9, the glue gun extrusion head 10 and the brush roller 14 to move to the side of the fixed pipe 4.

[0060] After shaping, the tank body is taken off the die barrel 2. First, turn the bolt on the fixed clamping plate 29 to release the fixation between the fixed clamping plate 29 and the limit rotating plate 28. Rotate the limit rotating plate 28 to separate the limit rotating plate 28 from the fixed clamping plate 29. At this time, the limit of the limit rotating plate 28 to the rotating support 22 is released. Pull the moving support 26 to drive the sliding plate 27 to slide inside the support chassis 1 until the fixed sleeve block 24 is separated from the fixed insertion rod 25. After the fixed sleeve block 24 is separated from the fixed insertion rod 25, the limit of the die barrel 2 to the driving pipe 3 is released. Rotate the rotating support 22 to drive the driving pipe 3, the rotating support 22, the third servo motor 23 and the support roller 35 to rotate to the side of the die barrel 2, so that the limit on the outer surface of one end of the die barrel 2 close to the driving pipe 3 is released. After the driving pipe 3 releases the support for the die barrel 2, the pulling sleeve block 32 provides a pulling force to the die barrel 2 and the fixed pipe 4, so that the die barrel 2 can be kept horizontal. Push the tank body on the outer surface of the die barrel 2 to take the tank body off the die barrel 2 along the driving pipe 3. After the tank body is taken off, rotate the driving pipe 3 in the reverse direction to make the rotating support 22 rotate to fit with the moving support 26. Push the rotating support 22 and the moving support 26 to insert the fixed insertion rod 25 back into the fixed sleeve block 24, and then rotate the limit rotating plate 28 to make the limit rotating plate 28 snap into the fixed clamping plate 29 and fix it with a bolt.
