Description

Technical Field

[0001] The present application relates to the field of plastic cup processing, and in particular to a plastic hydraulic cup making machine with an adjustment function. Background Art

[0002] The plastic hydraulic cup making machine is a device specially used for producing plastic cups, plastic containers or other plastic products. By quickly adjusting various parameters, it can shorten the production cycle and meet the needs of large-scale production.

[0003] Some existing hydraulic cup-making machines produce plastic cups by injecting molten plastic into a mold, then using hydraulic pressure to squeeze the molten plastic inside the mold, and completing the production of the plastic cups after the plastic cups cool down. However, it is extremely inconvenient to take the plastic cups out of the mold because the formed plastic cups cling to the inner wall of the mold. At this time, the plastic cups need to be manually picked out, which reduces the practicality of the cup-making machine. In addition, the mold needs to be fixed when in use. Some existing cup-making machines fix the mold by means of a buckle. Since the locking switch of the buckle is small, it is not very convenient to fix the mold. Utility Model Content

[0004] The present application provides a plastic hydraulic cup-making machine with an adjustment function. When the cup-making machine is used to produce plastic cups, after the cup is formed, it is convenient and simple to take it out from the mold, thereby improving the practicality of the cup-making machine. When using the cup-making machine, the mold is fixed in a simple way, and molds of different diameters can be fixed.

[0005] In order to achieve the above objectives, the present application adopts the following technical solution: a plastic hydraulic cup making machine with an adjustment function, the cup making machine comprising:

[0006] base;

[0007] A mounting cylinder is fixedly embedded in the center of one side of the base, and a cylinder is fixedly provided on one side of the mounting cylinder;

[0008] The first circular plates are movably embedded in the inner wall of the cylinder, and a push rod is fixedly provided at the center of one side of the first circular plates, so that the first circular plates can slide on the inner wall of the cylinder;

[0009] An air guide pipe is installed on the outer surface of the cylinder, and a hollow cylinder is installed at one end of the air guide pipe. The second circular plate slides inside the hollow cylinder, and the second circular plate squeezes the gas inside the hollow cylinder, so that the gas inside the hollow cylinder enters the interior of the cylinder through the air guide pipe;

[0010] The second circular plate is movably embedded in the inner wall of the hollow cylinder, and a cross bar is fixedly provided at the center of one side of the second circular plate. The second circular plate slides inside the hollow cylinder and squeezes the gas inside the hollow cylinder.

[0011] As a further improvement of the present application: a push plate is fixedly provided on one side of the cross bar, and the hollow cylinder is fixedly provided on one side of the base. The push plate facilitates the pushing of the cross bar, and pushing the push plate drives the cross bar to move.

[0012] As a further improvement scheme of the present application: a cylinder is installed on one side of the base, a fixing rod is fixedly provided at the output end of the cylinder, and a pressure plate is installed at one end of the fixing rod. The cylinder switch is controlled so that the output end of the cylinder drives the pressure plate to move downward, so that the pressure plate squeezes the molten plastic inside the mold.

[0013] As a further improvement of the present application: a threaded cylinder is fixedly embedded in the outer surface of the mounting cylinder, and a threaded rod is threadedly embedded in the inner wall of the threaded cylinder. The threaded rod rotates in different directions inside the threaded cylinder, so that the threaded rod drives the first arc plate to move to different positions of the second arc plate.

[0014] As a further improvement scheme of the present application: a first curved plate is movably provided on one side of the threaded rod, and a rotating plate is fixedly provided on the side of the threaded rod away from the first curved plate. When the first curved plate is tightly attached to the outside of the mold, the threaded rod rotates and the first curved plate does not rotate along with it. The rotating plate facilitates the rotation of the threaded rod, and rotating the rotating plate drives the threaded rod to rotate inside the threaded barrel.

[0015] As a further improvement scheme of the present application: a first telescopic rod is fixedly provided on the inner wall of the mounting tube, a second telescopic rod is movably embedded in one side of the first telescopic rod, and the second telescopic rod can slide inside the first telescopic rod, at this time pushing the second curved plate to make the second telescopic rod slide into the inside of the first telescopic rod.

[0016] As a further improvement scheme of the present application: a spring is provided on the outer surface of the second telescopic rod, and a second arc plate is fixedly provided on one side of the second telescopic rod. The spring will generate a reverse force when squeezed, and the spring generates a force to push the second arc plate, further enabling the second arc plate and the first arc plate to clamp the mold.

[0017] As a further improvement of the present application: a baffle is fixedly embedded on the inner wall of the cylinder, and one side of the baffle is arranged on one side of the first circular plate. The first circular plate is tightly attached to one side of the baffle due to gravity. The baffle creates a gap between the first circular plate and the air duct, which facilitates the entry of gas into the interior of the cylinder.

[0018] Compared with the prior art, the advantages and positive effects of this application are:

[0019] 1. In the present application, when using a cup-making machine to produce plastic cups, the mold is placed inside the mounting cylinder to fix it, and molten plastic is injected into the mold. At this time, the cylinder switch is controlled so that the cylinder output end drives the pressure plate to move downward, so that the pressure plate squeezes the molten plastic inside the mold. After the plastic cup is cooled and formed, the push plate is pushed to drive the cross bar to move, further causing the second circular plate to slide inside the hollow cylinder. The second circular plate squeezes the gas inside the hollow cylinder, so that the gas inside the hollow cylinder enters the cylinder through the air guide duct. The first circular plate can slide on the inner wall of the cylinder. At this time, the first circular plate is tightly attached to one side of the baffle due to gravity. The gas entering the cylinder pushes the first circular plate upward and further pushes the push rod, so that the push rod passes through the through hole in the middle of the mold and lifts up the plastic cup inside the mold. When using the cup-making machine to produce plastic cups, after the cup is formed, it is convenient and simple to take it out of the mold, thereby improving the practicality of the cup-making machine.

[0020] 2. In the present application, when fixing the mold, the second telescopic rod can slide inside the first telescopic rod, and at this time push the second curved plate, so that the second telescopic rod slides into the inside of the first telescopic rod, and the second curved plate and the first telescopic rod squeeze the spring. When the spring is squeezed, it will generate a reverse force. At this time, the mold is placed in the middle position of the first curved plate and the second curved plate, and the second curved plate is released. At this time, the spring generates a force to push the second curved plate, further making the second curved plate and the first curved plate clamp the mold. At this time, the rotating plate is rotated counterclockwise to drive the threaded rod to rotate inside the threaded barrel, and further making the threaded rod drive the first curved plate to move toward the second curved plate. When the rotating plate is difficult to rotate, the mold is fixed. Therefore, when using the cup making machine, the mold fixing method is simple, and molds of different diameters can be fixed.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways than those described herein. Therefore, the present application is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as Figures 1 to 5 As shown, the present application provides a plastic hydraulic cup making machine with an adjustment function, the cup making machine comprising:

[0030] Base 1;

[0031] The mounting tube 2 is fixedly embedded in the center of one side of the base 1, and a cylinder 201 is fixedly provided on one side of the mounting tube 2;

[0032] The first circular plates 202 are movably embedded in the inner wall of the cylinder 201, and a push rod 204 is fixedly provided at the center of one side of the first circular plates 202, so that the first circular plates 202 can slide on the inner wall of the cylinder 201;

[0033] An air guide duct 205 is mounted on the outer surface of the cylinder 201, and a hollow cylinder 206 is mounted on one end of the air guide duct 205. A second circular plate 207 slides inside the hollow cylinder 206, squeezing the gas inside the hollow cylinder 206 so that the gas inside the hollow cylinder 206 passes through the air guide duct 205 and enters the interior of the cylinder 201.

[0034] The second circular plate 207 is movably embedded in the inner wall of the hollow cylinder 206 , and a cross bar 208 is fixedly provided at the center of one side of the second circular plate 207 . The second circular plate 207 slides inside the hollow cylinder 206 and squeezes the gas inside the hollow cylinder 206 .

[0035] like Figures 1 to 5As shown, a push plate 209 is fixedly provided on one side of the cross bar 208 , and the hollow cylinder 206 is fixedly provided on one side of the base 1 . The push plate 209 facilitates the pushing of the cross bar 208 , and pushing the push plate 209 drives the cross bar 208 to move.

[0036] like Figures 1 to 5 As shown, a cylinder 210 is installed on one side of the base 1, and a fixed rod 211 is fixedly provided at the output end of the cylinder 210. A pressure plate 212 is installed at one end of the fixed rod 211. The switch of the cylinder 210 is controlled so that the output end of the cylinder 210 drives the pressure plate 212 to move downward, so that the pressure plate 212 squeezes the molten plastic inside the mold.

[0037] like Figures 1 to 5 As shown, a threaded cylinder 3 is fixedly embedded in the outer surface of the mounting cylinder 2, and a threaded rod 301 is threadedly embedded in the inner wall of the threaded cylinder 3. The threaded rod 301 rotates in different directions inside the threaded cylinder 3, so that the threaded rod 301 drives the first curved plate 302 to move to different positions of the second curved plate 307.

[0038] like Figures 1 to 5 As shown, a first curved plate 302 is movably provided on one side of the threaded rod 301, and a rotating plate 303 is fixedly provided on the side of the threaded rod 301 away from the first curved plate 302. When the first curved plate 302 is close to the outside of the mold, the threaded rod 301 rotates and the first curved plate 302 does not rotate along with it. The rotating plate 303 facilitates the rotation of the threaded rod 301. Rotating the rotating plate 303 drives the threaded rod 301 to rotate inside the threaded barrel 3.

[0039] like Figures 1 to 5 As shown, a first telescopic rod 304 is fixedly provided on the inner wall of the mounting tube 2, and a second telescopic rod 305 is movably embedded on one side of the first telescopic rod 304. The second telescopic rod 305 can slide inside the first telescopic rod 304. At this time, the second curved plate 307 is pushed to make the second telescopic rod 305 slide into the inside of the first telescopic rod 304.

[0040] like Figures 1 to 5 As shown, a spring 306 is movably sleeved on the outer surface of the second telescopic rod 305, and a second curved plate 307 is fixedly provided on one side of the second telescopic rod 305. The spring 306 will generate a reverse force when squeezed, and the spring 306 generates a force to push the second curved plate 307, further enabling the second curved plate 307 and the first curved plate 302 to clamp the mold.

[0041] like Figures 1 to 5 As shown, a baffle 203 is fixedly embedded on the inner wall of the cylinder 201. One side of the baffle 203 is set on one side of the first circular plate 202. The first circular plate 202 is tightly attached to one side of the baffle 203 due to gravity. The baffle 203 creates a gap between the first circular plate 202 and the air duct 205, which facilitates the entry of gas into the interior of the cylinder 201.

[0042] Working principle: When using the cup making machine to produce plastic cups, the mold is placed inside the mounting cylinder 2 and fixed. By injecting molten plastic into the mold, the cylinder 210 switch is controlled at this time, so that the output end of the cylinder 210 drives the pressing plate 212 to move downward, so that the pressing plate 212 squeezes the molten plastic inside the mold. After the plastic cup is cooled and formed, the push plate 209 is pushed to drive the cross bar 208 to move, further making the second circular plate 207 slide inside the hollow cylinder 206, and the second circular plate 207 squeezes the inside of the hollow cylinder 206. The gas in the hollow cylinder 206 is passed through the gas guide pipe 205 to the inside of the cylinder 201. The first circular plate 202 can slide on the inner wall of the cylinder 201. At this time, the first circular plate 202 is tightly attached to the side of the baffle 203 due to gravity. The gas entering the cylinder 201 pushes the first circular plate 202 upward and further pushes the ejector rod 204, so that the ejector rod 204 passes through the through hole in the middle of the mold and pushes up the plastic cup inside the mold. When using the cup making machine to produce plastic cups, after the cup is formed, it is taken out of the mold. The cup making machine is convenient and easy to take and has improved practicality. When fixing the mold, the second telescopic rod 305 can slide inside the first telescopic rod 304. At this time, the second curved plate 307 is pushed to make the second telescopic rod 305 slide into the inside of the first telescopic rod 304. The second curved plate 307 and the first telescopic rod 304 squeeze the spring 306. The spring 306 will generate a reverse force when squeezed. At this time, the mold is placed in the middle position between the first curved plate 302 and the second curved plate 307, and the second curved plate 307 is released. 07At this time, the spring 306 generates a force to push the second curved plate 307, further making the second curved plate 307 and the first curved plate 302 clamp the mold. At this time, the rotating plate 303 is rotated counterclockwise to drive the threaded rod 301 to rotate inside the threaded barrel 3, further making the threaded rod 301 drive the first curved plate 302 to move toward the second curved plate 307. When the rotating plate 303 is difficult to rotate, the mold is fixed. Therefore, when using the cup making machine, the mold fixing method is simple, and molds of different diameters can be fixed at the same time.
