Description

Technical Field

[0001] This utility model relates to the field of preform production technology, specifically to release agent spraying equipment and preform production line. Background Technology

[0002] In the production of precast components, a release agent needs to be sprayed onto the mold to facilitate demolding, thus requiring release agent spraying equipment to complete the spraying process. In actual production, some mold cavities are relatively narrow, thus placing higher demands on the release agent spraying equipment. For example, bridge deck components include the base plate, vertical walls, protective walls, and side walls, with the vertical walls, protective walls, and side walls spaced apart on the base plate. The molds used in the production of bridge deck components often have relatively narrow spaces and large spraying areas; therefore, how to better spray the molds of such products presents new requirements for release agent spraying equipment.

[0003] Furthermore, precast production lines that meet the production requirements of various types of precast components offer numerous advantages and have become a future development trend. Therefore, developing a coating equipment capable of meeting the coating requirements of molds used in the production of different precast components would be of great significance.

In specific implementation, the number of spray guns installed on the cantilever end 32 of the industrial robotic arm 3 can be selectively one, two, three, or four.

[0045] This application incorporates an industrial robotic arm 3 into the mold release agent spraying equipment, with the spray gun mounted on the robotic arm 3. This allows for better adjustment of the spray direction of the spray gun, thereby better meeting the mold release agent spraying requirements of complex mold cavities. Furthermore, the mold release agent spraying equipment also includes a support beam 11 and a support base 2. A travel guide rail 111 is provided on the support beam 11, and the support base 2 can travel along the travel guide rail 111.

In specific implementations, such as... Figures 1 to 4As shown, rack 5 is positioned directly above the supporting beam 11 and extends along the length of the supporting beam 11. The drive motor is connected to rack 5 via a transmission gear. In specific implementations, the drive motor can be selectively connected to the transmission gear via a speed change mechanism.

Furthermore, preferably, the drive motor is a servo motor, and the drive motor is controlled by a control unit.

[0047] This application includes a release agent spraying device comprising a rack 5, a drive motor, and a transmission gear.
