Description

Technical Field

[0001] This utility model belongs to the technical field, and specifically relates to a bag-supporting device for filling anion exchange resin. Background Technology

[0002] Anion exchange resins have wide applications in water treatment and chemical industries, and the design of the bag-supporting device in the filling process is crucial for improving work efficiency and ensuring product quality.

[0003] Existing bag-holding devices for filling anion exchange resins typically include a frame set on the ground and a clamping mechanism mounted on the frame. In use, the operator places the bag to be held onto the frame and uses the clamping mechanism to hold the bag.

[0004] However, during the clamping process, workers can only open and clamp bags of the same height. For bags of different heights, different height devices must be used to open and clamp the bags, resulting in low equipment versatility and failing to meet people's needs. Therefore, a bag-opening device for anion exchange resin filling is proposed. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the prior art by providing a bag-opening device for filling anion exchange resins. It not only meets the basic requirement of opening the bags, but also can adapt to bags of different heights through a lifting device, thereby improving the versatility of the equipment and meeting people's usage needs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a bag support device for filling anion exchange resin, including a U-shaped plate, fixing blocks are respectively provided on the left and right sides of the bottom of the U-shaped plate, a crossbar is provided at the bottom of the two fixing blocks, a lifting plate is slidably provided between the two fixing blocks, and two guide rods passing through the U-shaped plate are provided on the top rear side of the lifting plate.

[0007] As a further improvement of this utility model, support rods are respectively provided on the top left and right sides of the U-shaped plate, and a top plate is provided on the top of the two support rods. Clamping blocks are respectively provided on the inner ends of the two support plates, a feeding cylinder is provided in the middle of the top plate, and a hopper is provided on the top of the feeding cylinder.

[0008] As a further improvement of this utility model, the inner ends of the two fixed blocks are respectively provided with sliding grooves, and sliders are slidably arranged inside the two sliding grooves. A guide post passing through the slider is provided inside the left sliding groove, and a lead screw passing through the slider is rotatably arranged inside the right sliding groove. The lead screw is screwed to the slider. A first rotary motor connected to the lead screw is provided at the bottom of the right crossbar. The first rotary motor and the lead screw are connected by a coupling. A guide seat corresponding to the guide post is provided at the top of the U-shaped plate. Support legs are provided at the four corners of the bottom of the U-shaped plate. Anti-slip pads are provided at the bottom of the four support legs. A cross plate is provided between two adjacent support legs.

[0009] As a further improvement of this utility model, two support rods are provided on the front side of the top plate, and a slide rail is provided on the front side of the top plate. Two sliding bodies are slidably arranged inside the slide rail, and a movable plate is provided on the front side of each of the two sliding bodies. A bidirectional lead screw passing through the movable plate is rotatably arranged between the two support rods. A second rotary motor connected to the bidirectional lead screw is provided on the support rod. The second rotary motor is connected to the bidirectional lead screw through a coupling. An L-shaped plate is provided on the front side of each of the two movable plates. The bottom of each of the two L-shaped plates is provided with a semi-circular arc corresponding to the clamping block. A switch is provided on the right side of the U-shaped plate. The switch is electrically connected to the first rotary motor and the second rotary motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, this design includes a first rotary motor. The rotation of the first rotary motor drives the lead screw to rotate, which in turn drives the slider inside the slide to slide. At the same time, the left slider moves along the guide post, thereby driving the lifting plate to rise and fall. Meanwhile, the guide rod on the lifting plate moves up and down along the U-shaped plate, thus allowing the lifting plate to move up and down and thus support bags of different heights.

[0012] Secondly, this design includes a second rotary motor. The rotation of the second rotary motor drives the bidirectional lead screw to rotate, which in turn drives the moving plate to move. The movement of the moving plate causes the slide body to slide inside the slide rail, thereby moving the L-shaped plate. This allows the semicircular arc to correspond with the clamping plate and clamp the bag, thus fixing and opening it.

[0013] Thirdly, this design incorporates guide rods, which make the lifting plate more stable during the lifting process.

[0014] Fourth, this design incorporates multiple anti-slip pads, which make the device more stable during operation. Attached Figure Description

The device has two sliding bodies 116, and a movable plate 117 is fixedly connected to the front side of each sliding body 116. A bidirectional lead screw 118 passing through the movable plate 117 is rotatably connected between two support rods 114. A second rotary motor 208 connected to the bidirectional lead screw 118 is fixedly connected to the support rod 114. The second rotary motor 208 and the bidirectional lead screw 118 are connected by a coupling. An L-shaped plate 119 is fixedly connected to the front side of each of the two movable plates 117. A semi-circular arc 201 corresponding to the clamping block 120 is fixedly connected to the bottom of each of the two L-shaped plates 119.

[0023] like Figure 1 , 2 As shown, support rods 110 are respectively provided on the top left and right sides of the U-shaped plate 101. The top of the two support rods 110 are fixedly connected to the top plate 111. Clamping blocks 120 are respectively fixedly connected to the inner ends of the two support plates. A feed cylinder 112 is fixedly connected to the middle of the top plate 111. A hopper 113 is fixedly connected to the top of the feed cylinder 112. A guide seat 202 corresponding to the guide post 108 is provided on the top of the U-shaped plate 101.

[0024] like Figure 1 , 2 As shown in Figure 3, the inner ends of the two fixed blocks 102 are respectively provided with sliding grooves 106, and sliders 107 are slidably arranged inside the two sliding grooves 106. The guide post 108 passing through the slider 107 is fixedly connected inside the left sliding groove 106, and the lead screw 109 passing through the slider 107 is rotatably arranged inside the right sliding groove 106. The lead screw 109 is screwed to the slider 107. The bottom of the right crossbar 103 is fixedly connected to the first rotary motor 204 connected to the lead screw 109. The first rotary motor 204 and the lead screw 109 are connected by a coupling. The right side of the U-shaped plate 101 is fixedly connected to the switch 203.

The bottom of the four support legs 205 is respectively fixedly connected to the anti-slip pads 206. A crossbar 207 is fixedly connected between two adjacent support legs 205.

[0025] How to use this utility model:

[0026] When in use, the operator first turns on switch 203. Turning on switch 203 powers on the first rotary motor 204 and the second rotary motor 208. The operator then holds the bag and starts the second rotary motor 208. The rotation of the second rotary motor 208 drives the bidirectional lead screw 118 to rotate. The rotation of the bidirectional lead screw 118 drives the moving plate 117 to move. The movement of the moving plate 117 causes the slide body 116 to slide inside the slide rail 115, thereby driving the L-shaped plate 119 to move. This causes the semi-circular arc 201 to be aligned with the clamping plate and clamped, thus fixing and opening the bag.

[0027] At this time, the staff starts the first rotary motor 204. The rotation of the first rotary motor 204 drives the lead screw 109 to rotate. The rotation of the lead screw 109 drives the slider 107 inside the slide groove 106 to slide. At the same time, the left slider 107 moves along the guide column 108, thereby driving the lifting plate 104 to rise and fall. At this time, the guide rod 105 on the lifting plate 104 moves up and down along the U-shaped plate 101, thereby causing the lifting plate 104 to move up and down, so as to receive bags of different heights.

[0028] At this time, the staff adds material into the hopper 113 so that the material enters the middle of the bag. After the bag is full, the staff starts the first rotary motor 204, which lowers the lifting plate 104, making it easier for the staff to unload the material from the lifting plate 104.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
