Description

Technical Field

[0001] This application relates to the field of PP bottle production, and more specifically, to a PP bottle molding apparatus. Background Technology

[0002] A PP bottle molding device is a specialized piece of equipment used to process polypropylene (PP) material into plastic bottles. Its core function is to achieve rapid production of PP bottles through processes such as mold forming and cooling curing. It typically consists of a left outer mold, a right outer mold, and a forming inner mold, which are opened and closed by a drive mechanism (such as a cylinder or hydraulic cylinder) to form the shape of the bottle.

[0003] In the existing technology, PP bottle molding equipment can achieve flexible production of PP bottles of different specifications and types by setting up a multi-functional modular structure and using replaceable functional modules (such as molds, cooling systems, drive units, etc.), which not only meets diversified production needs, but also improves efficiency and resource utilization.

[0004] However, existing PP bottle molding equipment still has the following shortcomings during use: Most existing PP bottle molding equipment drives the molten preform to expand and adhere tightly to the inner wall of the mold by introducing compressed air into the mold. Existing PP bottle molding equipment usually has multiple sets of grooves in the mold to process multiple PP bottles at one time. When producing bottles of different sizes, existing PP bottle molding equipment requires the use of different molds. Due to the different sizes of PP bottles, the position of the compressed air output end needs to be adjusted. Existing PP bottle molding equipment is not convenient for adjusting the position of multiple sets of compressed air output ends. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a PP bottle molding device, which aims to improve the existing PP bottle molding device, which requires the use of different molds when producing bottles of different sizes. Due to the different sizes of PP bottles, the position of the compressed air output end needs to be adjusted, and the existing PP bottle molding device is not convenient for adjusting the position of multiple sets of compressed air output ends.

[0006] This application provides a PP bottle molding device, including a molding device body. The molding device body has a moving plate and a fixed plate inside. A first mold is provided on one side of the fixed plate, and a second mold is provided on one side of the moving plate. The output end of the molding device body is connected to multiple sets of air pipes, and the other end of the air pipes is connected to an output component. An adjustment mechanism for adjusting the position of the output component is provided on the outside of the molding device body, and a fixing mechanism for replacing the first mold and the second mold is provided inside the molding device body.

[0007] The adjustment mechanism includes a track component, on one side of which multiple sets of sliding grooves are formed, and protrusions are slidably connected inside the sliding grooves.

[0008] In one specific implementation, a first housing is connected to the outside of the molding device body, a motor is connected to the top of the first housing, the output shaft of the motor passes through the first housing and is connected to a screw, and the other end of the screw is rotatably connected to the inside of the first housing.

[0009] In the above implementation process, by setting up a motor, the output shaft of the motor can be controlled to rotate, thereby driving the screw to rotate inside the first housing.

[0010] In one specific implementation, the outer surface of the screw is threadedly connected to a threaded seat, which is slidably connected to the inner wall of the first housing.

[0011] In the above implementation process, by setting the screw, the threaded seat can be driven to move up and down inside the first housing when the screw rotates.

[0012] In one specific implementation, a connector is connected to one side of the threaded seat, and the connector is connected to one end of the track plate.

[0013] In the above implementation process, by setting the threaded seat, the track plate can be driven to move up and down through the connecting parts when the threaded seat moves.

[0014] In one specific implementation, the molding device body is externally connected to two sets of vertical plates, and a first crossbar and a second crossbar are connected between the two sets of vertical plates. A first slider is slidably connected to the outer surface of the first crossbar, and a second slider is slidably connected to the outer surface of the second crossbar.

[0015] In the above implementation process, by setting the first crossbar and the second crossbar, the first slider can slide on the outer surface of the first crossbar, and the second slider can slide on the outer surface of the second crossbar.

[0016] In one specific implementation, a U-shaped component is connected to one side of the first slider, the U-shaped component is connected to one side of the second slider, and a cylinder is connected to one side of the U-shaped component.

[0017] In the above implementation process, by setting the U-shaped part, when the U-shaped part moves, it can drive the first slider to slide on the outer surface of the first crossbar, and the second slider to slide on the outer surface of the second crossbar.

[0018] In one specific implementation, the protrusion is connected to one side of the U-shaped member, and the output member is connected to the output end of the cylinder.

[0019] In the above implementation process, by setting the protrusion, when the U-shaped part moves up and down, the protrusion can be driven to slide inside the sliding groove, drive the first slider to slide on the outer surface of the first crossbar, the second slider to slide on the outer surface of the second crossbar, and drive the cylinder to move, which can adjust the position of the output part. The cylinder is used to drive the output part to move downward, so that the output end of the output part is in close contact with the top of the mold.

[0020] In one specific implementation, the fixing mechanism includes two sets of mounting plates, which are respectively connected to one side of the first mold and the second mold. Each end of the mounting plate is connected to a clip, and a slot is provided on one side of the clip.

[0021] In the above implementation process, by setting the clips, the mounting plate can be fixed on one side of the moving plate and the fixed plate, thereby fixing the first mold and the second mold on one side of the moving plate and the fixed plate. Molds of different sizes are all connected to mounting plates of the same size.

[0022] In one specific implementation, four sets of fixing members for movable insertion clips are connected to one side of both the fixed plate and the movable plate. A second housing is connected to one side of the fixing member, and a movable member is slidably connected inside the second housing. A plug is connected to one side of the movable member, and one end of the plug passes through the fixing member and is movably inserted into the interior of the plug.

[0023] In the above implementation process, by setting the moving part, the movement of the moving part can be controlled to drive the plug-in to move, insert the card into the inside of the fixing part, and then insert the plug-in into the inside of the slot, thereby fixing the mounting plate on one side of the moving plate and the fixed plate.

[0024] In one specific implementation, a pull rod is connected to the other side of the movable component, one end of the pull rod passes through the second housing and is connected to a pull plate, and a spring is sleeved on the outer surface of the pull rod.

[0025] In the above implementation process, by setting up the pull plate, the pull rod can be moved by pulling the pull plate, which in turn moves the moving part. The spring can prevent the plug from falling out of the slot after it is inserted into the slot when the pull plate is not under force.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By adjusting the mechanism and fixing mechanism, the insert can be disengaged from the slot by pulling the pull plate, and the card can be removed from the fixing part. This disconnects the connection between the mounting plate and the fixed plate and the moving plate, allowing the installation plate to be replaced with one connected to another set of molds. Then, the insert can be inserted into the slot, thus completing the replacement of molds of different sizes. After the mold is replaced, the screw is rotated by controlling the motor, which moves the output parts so that multiple sets of output parts are moved directly above the corresponding air inlet of the mold. This solves the problem that existing PP bottle molding devices require different molds when producing bottles of different sizes. Because the size of the PP bottles is different, the position of the compressed air output end needs to be adjusted, and existing PP bottle molding devices are not convenient for adjusting the position of multiple sets of compressed air output ends.

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a PP bottle molding apparatus, including a molding apparatus body 1.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The molding device body 1 has a moving plate 6 and a fixed plate 4 inside. A first mold 5 is provided on one side of the fixed plate 4, and a second mold 7 is provided on one side of the moving plate 6. The output end of the molding device body 1 is connected to multiple sets of air pipes 8, and the other end of the air pipes 8 is connected to an output component 9. An adjustment mechanism 2 for adjusting the position of the output component 9 is provided on the outside of the molding device body 1. A fixing mechanism 3 for replacing the first mold 5 and the second mold 7 is provided inside the molding device body 1.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The adjustment mechanism 2 includes a track component, and multiple sets of sliding grooves 209 are opened through one side of the track component. The sliding grooves 209 are slidably connected to protrusions 208.

[0041] In a specific configuration, a first housing 2014 is connected to the outside of the molding device body 1. A motor 2013 is connected to the top of the first housing 2014. The output shaft of the motor 2013 passes through the first housing 2014 and is connected to a screw 2012. The other end of the screw 2012 is rotatably connected to the inside of the first housing 2014. By configuring the motor 2013, the screw 2012 can be driven to rotate inside the first housing 2014 by controlling the rotation of the output shaft of the motor 2013.

[0042] In a specific configuration, the outer surface of the screw 2012 is threadedly connected to a threaded seat 2011, which is slidably connected to the inner wall of the first housing 2014. The screw 2012 is configured such that when it rotates, the threaded seat 2011 moves up and down inside the first housing 2014.

[0043] In a specific configuration, a connector 2010 is connected to one side of the threaded seat 2011. The connector 2010 is connected to one end of the track plate 201. With the threaded seat 2011 in place, the connector 2010 can drive the track plate 201 to move up and down when the threaded seat 2011 moves.

[0044] In a specific configuration, the main body 1 of the molding device is externally connected to two sets of vertical plates 202. A first horizontal bar 203 and a second horizontal bar 204 are connected between the two sets of vertical plates 202. A first slider 205 is slidably connected to the outer surface of the first horizontal bar 203, and a second slider 206 is slidably connected to the outer surface of the second horizontal bar 204. The first slider 205 can slide on the outer surface of the first horizontal bar 203 and the second slider 206 can slide on the outer surface of the second horizontal bar 204 through the configuration of the first horizontal bar 203 and the second slider 206.

[0045] In a specific configuration, a U-shaped component 207 is connected to one side of the first slider 205, and the U-shaped component 207 is connected to one side of the second slider 206. A cylinder 10 is connected to one side of the U-shaped component 207. By setting the U-shaped component 207, the first slider 205 can slide on the outer surface of the first crossbar 203 and the second slider 206 can slide on the outer surface of the second crossbar 204 when the U-shaped component 207 moves.

[0046] In a specific configuration, the protrusion 208 is connected to one side of the U-shaped part 207, and the output part 9 is connected to the output end of the cylinder 10. The protrusion 208 is configured to slide inside the sliding groove 209 when the U-shaped part 207 moves up and down, causing the first slider 205 to slide on the outer surface of the first crossbar 203 and the second slider 206 to slide on the outer surface of the second crossbar 204. This also causes the cylinder 10 to move, adjusting the position of the output part 9. The cylinder 10 is used to move the output part 9 downward so that the output end of the output part 9 is in close contact with the top of the mold.

[0047] In a specific configuration, the fixing mechanism 3 includes two sets of mounting plates 301. The two sets of mounting plates 301 are respectively connected to one side of the first mold 5 and the second mold 7. Both ends of the mounting plates 301 are connected to clips 302. A slot 303 is provided on one side of the clips 302. By setting the clips 302, the mounting plates 301 can be fixed to one side of the moving plate 6 and the fixed plate 4, thereby fixing the first mold 5 and the second mold 7 to one side of the moving plate 6 and the fixed plate 4. Molds of different sizes are all connected to mounting plates 301 of the same size.

[0048] In the specific configuration, four sets of fixing members 305 for movably inserting the card 302 are connected to one side of both the fixed plate 4 and the movable plate 6. A second housing 304 is connected to one side of the fixing member 305. A movable member 307 is slidably connected inside the second housing 304. A plug 306 is connected to one side of the movable member 307. One end of the plug 306 passes through the fixing member 305 and is movably inserted into the interior of the plug 306. By controlling the movement of the movable member 307, the plug 306 can be moved to insert the card 302 into the interior of the fixing member 305. Then, the plug 306 is inserted into the interior of the slot 303, thereby fixing the mounting plate 301 to one side of the movable plate 6 and the fixed plate 4.

[0049] In a specific configuration, a pull rod 309 is connected to the other side of the movable component 307. One end of the pull rod 309 passes through the second housing 304 and is connected to a pull plate 3010. A spring 308 is sleeved on the outer surface of the pull rod 309. The pull plate 3010 allows the pull rod 309 to move by pulling the pull plate 3010, which in turn moves the movable component 307. The spring 308 prevents the plug 306 from dislodging from the slot 303 after it has been inserted into the slot 303, when the pull plate 3010 is not under force.

[0050] The working principle of this PP bottle molding device is as follows: When using the PP bottle molding device, pulling the pull plate 3010 moves the moving part 307, causing the insert 306 to disengage from the slot 303 and the clip 302 to be removed from the fixing part 305. This disconnects the connection between the mounting plate 301 and the fixed plate 4 and the moving plate 6, allowing replacement with a mounting plate 301 connected to another set of molds. Then, the insert 306 is inserted into the slot 303, thus completing the replacement of molds of different sizes. After replacing the mold, the motor 2013 drives the screw 2012 to rotate inside the first housing 2014, causing the threaded seat 2011 to rotate inside the first housing 2014. The internal movement of 14 causes the U-shaped part 207 to move up and down. The protrusion 208 slides inside the sliding groove 209, causing the first slider 205 to slide on the outer surface of the first crossbar 203 and the second slider 206 to slide on the outer surface of the second crossbar 204. This, in turn, causes the output part 9 to move, so that multiple sets of output parts 9 are all moved directly above the corresponding air inlet of the mold. This solves the problem that existing PP bottle molding devices require the use of different molds when producing bottles of different sizes. Because the size of the PP bottles is different, the position of the compressed air output end needs to be adjusted. Existing PP bottle molding devices are not convenient for adjusting the position of multiple sets of compressed air output ends.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
