Description

Technical Field

[0001] This invention belongs to the field of drip molding machines, and specifically relates to an oil drum with a pneumatic pressurization function. Background Technology

[0002] Drip molding is one of the few products that still largely relies on manual production processes. Its main raw material is PVC paste resin dissolved in DOP and other resins, with the addition of color paste to create mixtures of different colors. These mixtures are then dripped into molds made of aluminum, brass, electroforming, or silicone. By heating the mixtures to over 170 degrees Celsius, the PVC paste resin and DOP undergo a chemical reaction and solidify, resulting in products with rich colors and a strong three-dimensional effect.

[0003] A drip molding machine is used to produce drip-molded photo frames, drip-molded bag labels, and other similar products. The machine primarily relies on a three-dimensional motion system to guide the PVC paste dispensing needle to the designated position on the drip molding mold. The amount of glue dispensed is controlled by adjusting the resin extrusion time and the needle's movement speed. Drip molding machines mainly utilize CNC machining technology, replacing manual dispensing with automated machine dispensing, significantly improving production efficiency. This is an original technology independently developed in China.

[0004] In the drip molding process, the pressure and flow control of the material in the oil tank are extremely important. Existing drip molding machines are prone to problems such as insufficient material pressure and low flow during use. In particular, when the material level in the oil tank is low, insufficient oil pressure often leads to inadequate material supply. Summary of the Invention

[0005] In order to solve the problem of insufficient material supply caused by insufficient oil pressure when the material level in the oil drum is low in the existing technology, the purpose of this invention is to provide an oil drum with air pressure boosting function.

[0006] The technical solution adopted in this invention is as follows:

[0007] An oil drum with a pneumatic pressure boosting function includes a drum body, a drum cover, and a movable valve core. The bottom end of the drum body has a material outlet, and the top end of the drum body is fitted with a drum cover. The drum cover has a first mounting hole and an air inlet, both of which communicate with the inner cavity of the drum body. A movable valve core is movably installed in the first mounting hole. The air inlet is used to introduce compressed air into the inner cavity of the drum body. When compressed air is introduced into the air inlet, the compressed air drives the movable valve core to block the first mounting hole.

[0008] Optionally, a mounting beam is provided in the first mounting hole, and a second mounting hole is provided on the mounting beam, in which the movable valve core is slidably installed.

[0009] As optional, the movable valve core comprises a first baffle and a sliding rod, the first baffle is installed at one end of the sliding rod, and a detachable limiting piece is installed at the other end of the sliding rod; the sliding rod is slidably installed in the second mounting hole, and the first baffle and the limiting piece are located in the inner cavity of the barrel cover and outside, respectively; the limiting piece has an outer dimension smaller than the hole diameter of the first mounting hole and larger than the hole diameter of the second mounting hole; when compressed air is introduced into the air inlet hole, the compressed air drives the first baffle to block the first mounting hole.

[0010] As optional, the limiting piece is a nut, a snap ring or a baffle.

[0011] As optional, the first baffle further has a second baffle, the sliding rod is arranged on the second baffle, the second baffle is in the shape of a circular truncated cone, the first mounting hole has a tapered guide hole near one end of the second baffle, and the inner side wall of the guide hole is in contact with the outer side wall of the second baffle.

[0012] As optional, the bottom wall of the barrel body is a guide wall, the guide wall is arranged obliquely, and the lower end of the guide wall is connected with the material outlet.

[0013] As optional, the bottom end of the guide wall is provided with a mounting groove for mounting the barrel body.

[0014] As optional, the top end of the barrel body has an external thread segment, the barrel cover is threadedly connected with the external thread segment, and the outer side wall of the barrel cover has anti-skid teeth.

[0015] The present application has the following advantages:

[0016] The present application provides an oil drum with air pressure boosting function, comprising a barrel body, a barrel cover and a movable valve core; the bottom end of the barrel body is provided with a material outlet, and the top end of the barrel body is provided with the barrel cover; the barrel cover is provided with a first mounting hole and an air inlet hole, both of which are in communication with the inner cavity of the barrel body, and the movable valve core is movably installed in the first mounting hole; the air inlet hole is used for introducing compressed air into the inner cavity of the barrel body, and when compressed air is introduced into the air inlet hole, the compressed air drives the movable valve core to block the first mounting hole. By connecting the air inlet hole with the compressed air station outside, compressed air can be introduced into the barrel body, and when a large amount of compressed air is introduced, the airflow will drive the movable valve core to slide along the first mounting hole and block the first mounting hole, so that the inner cavity of the entire barrel body and barrel cover is in a sealed state, the pressure in the barrel body is increased, and the air pressure above the remaining material level in the barrel body pushes the remaining material out of the material outlet, effectively avoiding the problems of insufficient oil pressure and small flow when the material level is low. At the same time, the high air pressure in the barrel body solves the problem of material backflow. When used normally, the air inlet hole is disconnected from the compressed air station, and when the pressure in the barrel body is normal, the movable valve core automatically falls due to gravity, so that the inner cavity of the barrel body is in communication with the outside, and the internal and external atmospheres of the barrel body are consistent, which will not affect the normal use of the material.

By connecting the air inlet hole 22 with the compressed air station outside, the compressed air can be introduced into the drum body 1, and when a large amount of compressed air is introduced, the airflow will drive the movable valve core 3 to slide along the first mounting hole 21 and block the first mounting hole 21, so that the inner cavities of the drum body 1 and the drum cover 2 are in a sealed state, the pressure in the drum body 1 is increased, the air pressure above the remaining material level in the drum body 1 pushes the remaining material downward from the material outlet 11, effectively avoiding the problems of insufficient pressure and small flow when the material level is low, and the material backflow problem is solved when the air pressure in the drum body 1 is higher than the outside. In normal use, the air inlet hole 22 is disconnected with the compressed air station, and when the pressure in the drum body 1 is normal, the movable valve core 3 automatically falls due to gravity, so that the inner cavity of the drum body 1 is communicated with the outside through the first mounting hole 21, so that the inside and outside of the drum body 1 are consistent with the atmospheric pressure, and the normal use of the material will not be affected.

[0027] In the embodiment, as shown in Figure 1 , Figure 6 and Figure 7 , the first mounting hole 21 is provided with a mounting beam 23, the mounting beam 23 is provided with a second mounting hole 24, and the movable valve core 3 is slidably mounted in the second mounting hole 24.

[0028] In use, the drum cover 2 is unscrewed to add material for dripping into the drum body 1.
