The materials used to manufacture filter membranes are generally divided into three categories: fiber, synthetic resin, and ceramic. During the production process of filter membranes, they need to be cut.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A slitting and conveying device for filter membrane production includes an operating table and a guiding mechanism. The guiding mechanism includes two fixed seats bolted to the outer wall of the top of the operating table and two guide rollers that pass through both ends and are connected to the outer walls of the two fixed seats via bearings. A lifting mechanism is provided inside the operating table. The lifting mechanism includes a lifting cylinder bolted to the inner wall of the top of the operating table and a mounting frame bolted to the top of the piston rod of the lifting cylinder. A limiting assembly is provided inside the mounting frame. The limiting assembly includes an adjusting motor, a bidirectional screw connected to one end of the output shaft of the adjusting motor via a coupling, two limiting shafts that pass through and are bolted to the outer wall of the mounting frame, two adjusting plates screwed to the outer walls of both ends of the bidirectional screw, and four limiting rollers that pass through and are connected to the outer walls of the two adjusting plates via bearings. A conveying mechanism is provided on the top of the operating table. The mechanism includes two mounting bases welded to the top outer wall of the operating platform, a conveyor motor, a conveyor roller connected to one end of the output shaft of the conveyor motor via a coupling, and a top plate bolted to the top outer wall of the two mounting bases. Below the top plate is an extrusion assembly, which includes an extrusion cylinder, a mounting shaft connected to the extrusion cylinder via bearings, two connecting blocks bolted to both ends of the mounting shaft, and two extrusion springs. A support platform is bolted to the top outer wall of the operating platform, and a slitting assembly is mounted on the support platform. The slitting assembly includes a slitting cylinder and a slitting blade bolted to the top outer wall of the top plate. Fixing assemblies are located on both sides of the slitting blade. Each fixing assembly includes a fixing block, a fixing plate fixed to the lower outer wall of one side of the fixing block, several sliding rods fixed to the top outer wall of the fixing plate, and several return springs sleeved on the outer walls of the sliding rods.

[0009] Preferably, each of the four corners of the bottom outer wall of the mounting frame is bolted with a first limiting rod, and the four first limiting rods are respectively inserted through and slidably installed on the top inner wall of the operating table.

[0010] Preferably, a mounting bracket is fixed on one outer wall of the mounting frame, and the adjusting motor is connected to the outer wall of the mounting bracket by bolts. The two ends of the bidirectional screw pass through and are connected to the outer wall of the mounting frame by bearings. The two adjusting plates are slidably mounted on the outer walls of the two limiting shafts, and the four limiting rollers are slidably sleeved on the outer walls of the two limiting shafts.

[0011] With the above method, the bottom of the guide roller contacts the top of the filter membrane, the adjusting motor drives the adjusting plate to move along the two limiting shafts, so that the two limiting rollers limit the two sides of the filter membrane. Then, the piston rod of the lifting cylinder drives the mounting frame to rise, and the mounting frame drives the two limiting rollers to rise, thereby adjusting the surface tension of the filter membrane.

[0012] Preferably, a fixing frame is welded to one outer wall of the mounting base, and the conveying motor is bolted to the outer wall of the fixing frame. The two ends of the conveying roller pass through and are connected to the outer walls of the two mounting bases through bearings. Two support rods are bolted to the bottom outer wall of the top plate, and the two support rods are bolted to the top outer wall of the operating table.

[0013] Preferably, each of the two mounting bases has a slide rail on its upper outer wall, and the two ends of the mounting shaft are slidably mounted in the two slide rails respectively. Each of the two connecting blocks has a mounting groove on its top outer wall, and two compression springs are respectively fitted into the two mounting grooves. The top plate has two fixing grooves on its bottom outer wall, and two compression springs are respectively fitted into the two fixing grooves.

[0014] With the above scheme, one end of the filter membrane passes between the conveying roller and the extrusion cylinder. The filter membrane is squeezed by the extrusion cylinder. Under the action of two sets of extrusion springs, the extrusion cylinder squeezes the filter membrane. The output shaft of the conveying motor drives the conveying roller to rotate and convey the filter membrane.

[0015] Preferably, the bottom end of the piston rod of the slitting cylinder is bolted to a connecting plate, and two second limiting rods are bolted to the top outer wall of the connecting plate.

[0017] The above scheme involves the piston rod of the slitting cylinder driving the connecting plate and two fixed blocks to descend. The fixed blocks first contact the filter membrane, and then the connecting plate continues to descend, squeezing multiple return springs. Under the tension of the return springs, the fixed blocks squeeze the filter membrane, and then the slitting blade slits the filter membrane.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The bottom of the guide roller contacts the top of the filter membrane. The adjusting motor drives the adjusting plate to move along the two limiting shafts, so that the two limiting rollers limit the two sides of the filter membrane. Then, the piston rod of the lifting cylinder drives the mounting frame to rise, and the mounting frame drives the two limiting rollers to rise, thereby adjusting the surface tension of the filter membrane. This can limit the two sides of the filter membrane during transportation and adjust the surface tension of the filter membrane to prevent the filter membrane from shifting, thus improving its practicality.

[0020] 2. The piston rod of the slitting cylinder drives the connecting plate and two fixed blocks to descend. The fixed blocks first contact the filter membrane, and then the connecting plate continues to descend. The connecting plate squeezes multiple return springs. Under the tension of the return springs, the fixed blocks squeeze the filter membrane. Then the slitting blade cuts the filter membrane. This can squeeze and fix the filter membrane during the cutting process, preventing the filter membrane from moving and improving the cutting efficiency.

[0021] In summary, this utility model can limit the two sides of the filter membrane during transportation and adjust the surface tension of the filter membrane to prevent the filter membrane from shifting, thus improving its practicality. It can also squeeze and fix the filter membrane during slitting to prevent the filter membrane from moving during slitting, thus improving slitting efficiency. Attached Figure Description
