Description

Technical Field

[0001] This utility model relates to the field of quartz stone slab production equipment, and in particular to a quartz stone slab pulling machine. Background Technology

[0002] The production process of quartz stone slabs mainly includes the following steps: raw material preparation, mixing and stirring, pressing, heating and curing, and post-treatment. Among them, the curing of quartz stone slabs is a key step in the production process, which directly affects the hardness, density, and durability of the final product. Before curing, the quartz stone slabs are not hard enough, so they are connected with rubber sheets. The quartz stone slabs are pulled into the curing box by pulling the rubber sheets. The equipment used in the process of entering the curing box is a plate pulling machine. The existing plate pulling machines have a low degree of automation and still require manual intervention during the plate pulling process. Therefore, it is necessary to design a quartz stone extra-large slab plate pulling machine with a high degree of automation that does not require manual intervention. Summary of the Invention

[0003] The purpose of this utility model is to provide a quartz stone slab pulling machine, which has the advantages of requiring no manual intervention and having a high degree of automation.

[0004] The technical solution adopted is as follows:

[0005] A quartz slab pulling machine includes a frame, a conveyor belt mounted on the frame, a pulling frame slidably mounted on the frame above the conveyor belt, a drive mechanism at the upper end of the pulling frame, the drive mechanism including two drive gears, two racks on the frame meshing with the drive gears, a rotating plate hinged to the front end of the pulling frame, a telescopic cylinder hinged to the front end of the pulling frame, the other end of the telescopic cylinder rotatably connected to the rotating plate, multiple parallel telescopic cylinders mounted on the upper end of the rotating plate, each telescopic cylinder connected to a pressure plate, a long groove corresponding to the telescopic cylinder on the rotating plate, a support plate corresponding to the pressure plate at the other end of the long groove, and a limit switch corresponding to the frame mounted on the pulling frame.

[0006] Preferably, the drive mechanism includes a motor and a reducer. The reducer is provided with an input shaft and an output shaft. The input shaft is connected to the motor, and the two ends of the output shaft are respectively connected to two drive gears.

[0007] Preferably, the output shaft is provided with a drive sprocket, the pull plate frame is provided with a mounting bracket, the mounting bracket is equipped with an encoder, the encoder is connected to a driven sprocket, and a transmission chain is provided between the driven sprocket and the drive sprocket.

[0008] Preferably, the side of the frame is provided with a cable chain bracket, the pull plate frame is connected to the cable chain, and the cable chain is provided with a cable connected to the drive mechanism.

[0009] Preferably, both sides of the pull plate frame are equipped with multiple limit wheels and support wheels that rotate horizontally and vertically, and the frame is provided with guide rails corresponding to the support wheels.

[0010] Compared to existing technologies, the advantages are:

[0011] In this invention, during the process of pulling quartz stone slabs into the curing chamber, a telescopic hydraulic cylinder controls the rotation of a rotating plate, allowing the rubber sheet to enter the long groove. The telescopic cylinder extends and uses a pressure plate to hold down the support plate. As the pulling frame moves, it moves the rubber sheet and the quartz stone slab into the curing chamber. The telescopic cylinder then retracts to release the rubber sheet, and the pulling frame leaves the curing chamber. After curing, the pulling frame moves back into the curing chamber, and the rotating plate pulls the cured quartz stone slab out of the curing chamber. The entire process requires no manual operation and has a high degree of automation. Attached Figure Description
