Description

Technical Field

[0001] This utility model belongs to the technical field of row-type bottle making machine, and in particular relates to a mold spraying device for bottle making machine. Background Technology

[0002] Currently, in the glassware manufacturing industry, row-type bottle-making machines are one of the equipment used specifically for producing bottles and jars. The spraying mechanism used to apply release agent to the initial mold and the forming mold requires regular maintenance and replacement of the spray guns. This process requires repeated disassembly and assembly of the fixed connecting parts (bolts, etc.), which leads to the following problems:

[0003] The assembly process requires adjusting and correcting assembly accuracy, resulting in low assembly efficiency.

[0004] Repeated disassembly and assembly will cause wear and tear, affecting assembly accuracy;

[0005] Even after disassembly, the row-type bottle making machine continues to operate, so the spraying of the release agent is done manually, which greatly increases the labor intensity and affects work efficiency and product quality.

[0006] At the same time, the existing spraying mechanism also has the following drawbacks:

[0007] 1. Spraying release agent into the mold using a long gun restricts the coating on the bottom of the mold, resulting in a higher product defect rate and severe mold wear;

[0008] 2. Using PU tubing or other fittings for air and material delivery in the spray gun's oil and air circuits can easily lead to oil and air leaks. Furthermore, the large number of air and oil pipes increases the overall size and volume of the mechanism.

[0009] This increases the risk of interference or collisions with other organizations, and also affects the aesthetics of the equipment;

[0010] 3. The spraying effect of the release agent is affected by the ambient temperature, especially in winter when the ambient temperature is too low, which leads to a reduction in the amount of release agent sprayed and poor atomization effect. Utility Model Content

[0011] In view of the deficiencies in the existing technology, this utility model provides a mold spraying device for bottle making machine, which can achieve quick assembly and disassembly without affecting assembly efficiency and assembly accuracy, while ensuring work efficiency and finished product quality.

[0012] The technical solution provided by this utility model is: a mold spraying device for a bottle making machine, including a robotic arm body, a spray gun mounting frame is provided downstream of the robotic arm body, and a quick-change assembly is provided between the end of the robotic arm body and the spray gun mounting frame.

[0013] Multiple pneumatic valves are positioned and installed on the spray gun mounting bracket. Each pneumatic valve is equipped with a mold wall spray gun or a mold bottom spray gun. The length of the mold wall spray gun is greater than the length of the mold bottom spray gun.

[0014] The spray gun mounting bracket has an integrally formed air passage and a mold release agent channel. The air passage is connected to the pneumatic valve, and the mold release agent channel is connected to the mold wall spray gun and the mold bottom spray gun.

[0015] As an improvement, the quick-change component is an industrial robot quick-change disc, with one side of the industrial robot quick-change disc installed at the end of the robotic arm body and the other side installed at the end of the spray gun mounting bracket.

[0016] As a further improvement, the two discs of the industrial robot quick-change disc are respectively provided with at least two positioning pins and positioning holes that cooperate with the positioning pins.

[0017] As an improvement, each spray gun mounting bracket corresponding to the position of each pneumatic valve is provided with a positioning groove, and the pneumatic valve is positioned and installed in the positioning groove.

[0018] As an improvement, the spray nozzles on the mold wall spray gun are arranged in a ring and face the inner wall of the mold, while the spray holes on the mold bottom spray gun face vertically towards the bottom of the mold.

[0019] As an improvement, the spray gun mounting bracket is a metal spray gun mounting bracket, and at least one receiving channel is integrally formed inside the spray gun mounting bracket, and a heating element is provided in the receiving channel.

[0020] As a further improvement, a connecting arm is also included, wherein the quick-change assembly is disposed at the end of the robotic arm body and the end of the connecting arm; a transition connecting block is installed below the other end of the connecting arm, and the transition connecting block is fixedly connected to the spray gun mounting bracket.

[0021] The connecting arm is provided with a through channel through which both the gas delivery pipe for conveying gas and the mold release agent delivery pipe for conveying mold release agent pass.

[0022] One corner of the transition connection block is provided with a connector mounting seat. The air delivery pipe and the mold release agent delivery pipe are both connected to the connector mounting seat through a connector. The transition connection block is provided with a transition air passage that communicates with the air passage and a transition mold release agent channel that communicates with the mold release agent channel. The air delivery pipe communicates with the transition air passage, and the mold release agent delivery pipe communicates with the transition mold release agent channel.

[0023] As a further improvement, the robotic arm body is a six-axis robotic arm.

[0024] By adopting the above-described technical solution, the beneficial effects of the mold spraying device for bottle making machine provided by this utility model are as follows:

[0025] The bottle-making machine mold coating device includes a robotic arm body, with a spray gun mounting bracket downstream of the robotic arm body. A quick-change assembly is located between the end of the robotic arm body and the spray gun mounting bracket. Multiple pneumatic valves are positioned on the spray gun mounting bracket, each with a mold wall spray gun or a mold bottom spray gun mounted on it. The length of the mold wall spray gun is greater than the length of the mold bottom spray gun. An air passage and a mold release agent channel are integrally formed within the spray gun mounting bracket. The air passage is connected to the pneumatic valves, and the mold release agent channel is connected to the mold wall spray gun and the mold bottom spray gun. Based on this structure, the bottle-making machine mold coating device is used... In this system, quick-change components enable rapid disassembly and assembly during maintenance and spray gun replacement. Compared to traditional fixed connectors, this method ensures high assembly precision after disassembly, while also offering high efficiency, precision, and low wear from repeated disassembly and assembly. Furthermore, it ensures the continuous operation of the row-type bottle-making machine and the spraying device, significantly reducing human intervention and guaranteeing work safety, efficiency, and product quality. In addition, the built-in air path and mold release agent channel effectively solve oil and air leakage problems while ensuring a consistent spraying effect.

[0026] Because each of the two plates of the industrial robot quick-change plate is equipped with at least two positioning pins and positioning holes that cooperate with the positioning pins, the quick-change plate of the industrial robot can be quickly and accurately assembled with low wear rate through the cooperation of the positioning pins and positioning holes; this ensures that there is no need to adjust and correct the assembly accuracy and that the assembly efficiency is high.

[0027] Since each pneumatic valve is positioned in a positioning groove on the spray gun mounting bracket, the pneumatic valve is positioned and installed in the positioning groove, thereby effectively improving the assembly efficiency and accuracy of the pneumatic valve.

[0028] Because the spray nozzles on the mold wall spray gun are arranged in a ring and face the inner wall of the mold, while the spray holes on the mold bottom spray gun face the bottom of the mold vertically, this arrangement further ensures the spraying effect of the demolding machine on the inner wall and bottom of the mold, effectively avoiding the problems of increased product defect rate and severe mold wear caused by restricted spraying.

[0029] Because the spray gun mounting bracket is made of metal, it has at least one integrally formed receiving channel. A heating element is installed in the receiving channel to heat the spray gun mounting bracket, ensuring good atomization of the release agent in a low-temperature environment, thus effectively guaranteeing the quality of the coating and the product.

[0030] The bottle-making machine's mold spraying device also includes a connecting arm, with a quick-change assembly located at the end of the robotic arm and the end of the connecting arm. A transition connecting block is installed below the other end of the connecting arm, and the transition connecting block is fixedly connected to the spray gun mounting bracket. The connecting arm has a through channel through which both the gas delivery pipe and the mold release agent delivery pipe pass. One corner of the transition connecting block has a connector mounting seat, and both the gas delivery pipe and the mold release agent delivery pipe are connected to the connector mounting seat via connectors. The transition connecting block has a transition gas path connected to the gas path and a transition mold release agent channel connected to the mold release agent channel. The gas delivery pipe is connected to the transition gas path, and the mold release agent delivery pipe is connected to the transition mold release agent channel. Thus, through the combination of the connecting arm and the transition connecting block, a transition between the robotic arm and the spray gun mounting bracket is achieved. This not only allows the gas delivery pipe and the mold release agent delivery pipe to pass through and be stored on the connecting arm, avoiding space occupation and interference or collisions, but also facilitates connection with the transition gas path and the transition mold release agent channel, while also being aesthetically pleasing.
