Description

Technical Field

[0001] This application relates to the technical field of feed cylinders, and in particular to a feed cylinder for a sheet metal forming machine. Background Technology

[0002] In the production of foam boards, raw materials need to be sucked into a material cylinder for storage, and then discharged from the material cylinder into the production equipment. The traditional method is to install a fan between the material cylinder and the feeding machine. The fan rotates, and the raw materials are sucked into the material cylinder through the fan. Since the raw materials come into direct contact with the fan during the process of entering the material cylinder, and the raw materials of foam boards are flammable materials, the impeller of the fan collides violently with the raw materials of the foam boards. The impeller of the fan may generate high temperatures, and the raw materials of the foam boards are prone to combustion, causing safety hazards. Utility Model Content

[0003] The purpose of this application is to provide an inlet / outlet cylinder for a sheet forming machine to prevent the raw material of foam board from contacting the blades of the blower.

[0004] The technical solution provided in this application for an inlet / outlet cylinder for a sheet metal forming machine is as follows: it includes a cylinder body and a blower. The cylinder body is connected to an inlet pipe and an outlet pipe. The inlet pipe is connected to an inlet valve, and the outlet pipe is connected to an outlet valve. The blower is connected to an exhaust pipe and an exhaust pipe. Both the exhaust pipe and the exhaust pipe are connected to the cylinder body. The exhaust pipe is connected to an exhaust valve, and the exhaust pipe is connected to an exhaust valve. The exhaust pipe is connected to an inlet pipe, and the inlet pipe is connected to an inlet valve. The exhaust pipe is connected to an outlet pipe, and the outlet pipe is connected to an outlet valve.

[0005] By adopting the above technical solution, when feeding material into the cylinder, the discharge valve, inlet valve, and vent valve are closed, while the extraction valve, vent valve, and feed valve are opened. The blower rotates, and the gas inside the cylinder passes through the extraction pipe and exits through the vent pipe. The gas pressure inside the cylinder decreases, causing the raw material in the feed pipe to be drawn into the cylinder, thus preventing the raw material from contacting the blower blades and preventing combustion due to friction. When discharging material from the cylinder, the discharge valve, inlet valve, and vent valve are opened, while the extraction valve, vent valve, and feed valve are closed. The blower rotates, and external gas passes through the inlet pipe and exits through the vent pipe into the cylinder. The gas pressure inside the cylinder increases, causing the raw material inside the cylinder to exit through the discharge pipe.

[0006] Optionally, the cylinder is connected to a cleaning pipe, and the cleaning pipe is connected to a cleaning valve.

[0007] By adopting the above technical solution, the raw material will adhere to the inside of the barrel due to static electricity. When it is necessary to clean the inside of the barrel, open the cleaning valve, air inlet valve and air vent valve, close the discharge valve, air extraction valve, air vent valve and feed valve, the fan will rotate, and the outside gas will pass through the air inlet pipe and be discharged into the barrel through the air vent pipe. The air pressure inside the barrel will increase, causing the raw material adhering to the barrel to be discharged from the cleaning pipe, thus completing the cleaning.

[0008] Optionally, the feed pipe includes a main pipe and at least two branch pipes connected to the main pipe, the feed valve is connected to the main pipe, and the end of each branch pipe away from the main pipe is connected to the cylinder, with all the branch pipes being spaced apart from the cylinder.

[0009] By adopting the above technical solution, multi-point feeding helps the raw materials to be dispersed in the cylinder, reduces the accumulation of raw materials, and facilitates the discharge of raw materials from the discharge pipe.

[0010] Optionally, the cylinder is rotatably connected to a rotating shaft, the rotating shaft is provided with a plurality of stirring blades, the plurality of stirring blades are spaced apart along the length direction of the rotating shaft, and the cylinder is connected to a linkage assembly for driving the rotating shaft to rotate.

[0011] By adopting the above technical solution, the linkage component drives the rotating shaft to rotate, that is, several stirring blades rotate around the axis of the rotating shaft. During the rotation, the stirring blades drive the accumulated raw materials to move, reduce the accumulation of raw materials, and make the raw materials dispersed at the bottom of the cylinder, so that the raw materials can be discharged from the discharge pipe.

[0012] Optionally, the linkage assembly includes a toothed belt, a driven gear connected to the rotating shaft, a driving gear rotatably connected to the cylinder, and a driving member for driving the driving gear to rotate. The driving member is connected to the cylinder, the toothed belt is sleeved on the driven gear and the driving gear, and both the driven gear and the driving gear mesh with the toothed belt. The radius of the driving gear is smaller than the radius of the driven gear.

[0013] By adopting the above technical solution, the radius of the driving gear is smaller than that of the driven gear, resulting in a speed reduction and torque increase effect, and better control of the rotational speed of the shaft.

[0014] Optionally, two adjacent stirring blades are staggered on the rotating shaft.

[0015] By adopting the above technical solution, the staggered arrangement of the stirring blades on the rotating shaft can make the raw materials more evenly stirred in the cylinder, and avoid the accumulation of raw materials in the cylinder.

[0016] Optionally, each of the stirring blades is connected to a connecting rod that passes through the rotating shaft and is threaded with two nuts, with the rotating shaft located between the two nuts.

[0017] By adopting the above technical solution, the connecting rod passes through the rotating shaft and is fixed by two nuts, which effectively prevents the stirring blades from loosening or falling off during rotation, thus improving the reliability of equipment operation. Furthermore, this detachable connection method facilitates the replacement and maintenance of the stirring blades, reducing the operating cost of the equipment.

[0018] Optionally, the cylinder is connected to a horizontal pipe, which is connected to the cylinder via several connecting pipes. The ends of the exhaust pipe and the vent pipe away from the fan are both connected to the horizontal pipe. An anti-suction net is connected to the end of the connecting pipe away from the horizontal pipe, and the anti-suction net is located inside the cylinder.

[0019] By adopting the above technical solution, the anti-suction net effectively prevents raw materials from being directly sucked into the exhaust pipe and avoids direct contact between the raw materials and the blower.

[0020] Optionally, a rotary paddle level switch is connected inside the cylinder, and a controller is connected to the cylinder. The rotary paddle level switch, the feed valve, the discharge valve, the suction valve, the vent valve, the inlet valve, and the outlet valve are all electrically connected to the controller.

[0021] By adopting the above technical solution, the rotary paddle level switch can monitor the material position inside the cylinder in real time and transmit the signal to the controller. The controller automatically controls the opening and closing states of the feed valve, discharge valve, suction valve, venting valve, air inlet valve, and air outlet valve based on the signal from the level switch, thereby achieving automated management of the feeding and discharging process. This design effectively avoids misjudgments and delays that may occur due to manual operation in traditional methods, improves production efficiency, and reduces safety hazards.

[0022] Optionally, the cylinder is rotatably connected to an observation window.

[0023] By adopting the above technical solution, the observation window allows staff to observe the storage status of raw materials inside the cylinder in real time without opening the cylinder, improving the convenience and safety of operation.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When it is necessary to feed material into the cylinder, close the discharge valve, air inlet valve and vent valve, and open the suction valve, air outlet valve and feed valve. The fan will rotate, and the gas in the cylinder will pass through the suction pipe and be discharged from the air outlet pipe. The air pressure in the cylinder will decrease, so that the raw material in the feed pipe will be sucked into the cylinder, thereby avoiding contact between the raw material and the fan blades and preventing the raw material from burning due to friction with the fan blades.

[0026] 2. The linkage component drives the rotating shaft to rotate, that is, several stirring blades rotate around the axis of the rotating shaft. During the rotation, the stirring blades drive the accumulated raw materials to move, reduce the accumulation of raw materials, and make the raw materials dispersed at the bottom of the cylinder, so that the raw materials can be discharged from the discharge pipe.
