Description

Technical Field

[0001] The utility model belongs to the technical field of filter screen processing, in particular to a pump inlet filter screen processing device. Background Art

[0002] The pump inlet filter is used in the pumping system to protect the pump from damage by impurities and particles, avoid pipe blockage and pump overload, and ensure the reliability and safety of the system. When producing the pump inlet filter, the raw materials of the filter are first rolled by a rolling machine, and then sent to a cold welding machine for welding at the joints. This process is inefficient when operated manually, and when the rolled filter is removed from the rolling shaft, it may be pressed down by the rolling shaft and rotated by the rolling roller below, causing damage to the hands. In addition, when manually welding the joints of the rolled filter, continuous manual loading, unloading and docking are required, which makes the welding efficiency low.

[0003] To this end, we provide a pump inlet filter processing equipment to solve the above problems. Utility Model Content

Example

[0029] See also Figures 1 to 4 The utility model is a pump inlet filter processing equipment, including a rolling device 1 and a welding device 2. The rolling device 1 includes a support frame 101, a pressing component 102, a rolling shaft 103, a rolling roller 104 and a pushing component 105. The support frame 101 includes a vertical plate 101a. A pushing slider 105a is fixedly installed at the telescopic end of a pushing cylinder 105b in the pushing component 105, so that a pushing arm 105a-1 on one side of the pushing slider 105a is in contact with the rolling roller 103.

[0030] Specifically, the push-out assembly 105 includes a push-out slider 105a and a push-out cylinder 105b. The push-out slider 105a is fixedly mounted on the telescopic end of the push-out cylinder 105b. The push-out cylinder 105b is fixedly mounted on one side of the vertical plate 101a. The axis of the extended end of the push-out cylinder 105b is parallel to the axis of the rolling shaft 103.

[0031] The pressing assembly 102 is mounted on the horizontal arm 101b, and the welding device 2 is mounted on an end of the base 101c away from the vertical plate 101a.

[0032] Furthermore, a sliding block 103a is fixedly provided at one end of the rolling shaft 103, and a sliding groove 101a-1 is opened on the surface of the vertical plate 101a. The sliding block 103a is slidably sleeved in the sliding groove 101a-1, and a return spring 103b is fixedly connected to the bottom of the sliding block 103a. One end of the return spring 103b away from the sliding block 103a is fixedly connected to the bottom end of the sliding groove 101a-1, and a cross arm 101b is fixedly provided on the surface of one side of the vertical plate 101a.

[0034] Furthermore, the pressing assembly 102 includes a pressing punch plate 102a and a pressing cylinder 102b, two pressing punches 102a-1 are fixedly provided at both ends of the lower end plate surface of the pressing punch plate 102a, and the end of the pressing punch 102a-1 away from the pressing punch plate 102a is provided with an arc surface, and the side plate surface of the pressing punch plate 102a away from the pressing punch 102a-1 is fixedly connected to the telescopic end of the pressing cylinder 102b, and the pressing cylinder 102b is fixedly installed on the cross arm 101b, and the protruding end of the pressing cylinder 102b presses the pressing punch plate 102a downward, so that the arc surface of the pressing punch 102a-1 fits against the rolling shaft 103 and the rolling shaft 103 presses the filter screen downward.

[0035] The operation process of this embodiment is as follows:

[0036] The filter screen plate is sent to the top of the rolling roller 104, and the downward pressure cylinder 102b is started to make the downward pressure punch 102a-1 move the rolling shaft 103 downward to press the filter screen onto the rolling roller 104. The rolling roller 104 is driven by the motor to rotate to roll the filter screen plate. After the filter screen plate is rolled, the pushing cylinder 105b is started to push out for a while, and the rolled filter screen is pushed to the end of the rolling shaft 103, and the welding device 2 performs seam welding. Example

[0037] See also Figures 1 to 6On the basis of Example 1, the welding device 2 includes a welding table 201, a cold welding component 202 and a seam assembly 203. In the welding device 2 arranged at the end of the winding shaft 103, the seam motor 203a rotates to drive the seam rotating wheel 203b on the output shaft to rotate, so that the cylindrical filter screen on the winding shaft 103 rotates until the seam of the filter screen is stuck by the seam clamp and stops rotating, and then the cold welding wheel 202a welds the seam. After welding is completed, the winding shaft 103 is pushed out by the second stage of the pushing cylinder 105b to complete the unloading, thereby improving the welding efficiency.

[0038] Specifically, the seam assembly 203 includes a seam motor 203a and a seam rotating wheel 203b.

The axis of the seam rotating wheel 203b is parallel to the axis of the winding shaft 103.

[0039] Furthermore, the cold welding assembly 202 includes a cold welding wheel 202a and a wheel seat 202b. The cold welding wheel 202a is rotatably installed in the wheel seat 202b. A wheel seat slide rail 201a is fixedly provided on one side of the welding table 201. The wheel seat 202b is slidably installed in the wheel seat slide rail 201a. A rack 202b-1 is fixedly installed on the side of the wheel seat 202b away from the cold welding wheel 202a. The rack 202b-1 is meshed with the gear on the output end of the stepper motor. The rotation of the stepper motor causes the gear to drive the rack 202b-1 to drive the wheel seat 202b to move along the wheel seat slide rail 201a, thereby welding the seams of the filter cylinder.

[0040] Furthermore, a seam clamp 202b-2 is fixedly installed on one side of the wheel seat 202b where the cold welding wheel 202a is installed. The side of the seam clamp 202b-2 away from the wheel seat 202b is in contact with the outer surface of the winding shaft 103 and is perpendicular to the axial surface of the winding shaft 103. The seam clamp 202b-2 is used to be inserted into the seam of the filter cylinder to facilitate the welding of the seam by the cold welding wheel 202a.

[0041] The operation process of this embodiment is as follows:

[0042] The seam motor 203a rotates to make the seam rotating wheel 203b drive the cylindrical filter screen on the winding shaft 103 to rotate. When the seam of the cylindrical filter screen is clamped by the seam clamp 202b-2 to stop the cylindrical filter screen from rotating, the stepper motor drives the wheel seat 202b to move so that the cold welding wheel 202a welds the seam.
