Description

Technical Field

[0001] The utility model relates to the technical field of ton bag cutting, in particular to a novel molybdenum concentrate ton bag cutting device. Background Art

[0002] At present, molybdenum concentrate is generally stored in ton bags. First, the bag cutting process is required, and then it is passed into the dryer for drying before it can be used normally. The existing molybdenum concentrate bag cutter is in the shape of a cross. During processing, the ton bag is first lifted and then smashed on the bag cutter. At this time, gravity is used to open the lower part of the ton bag, and then the material discharge process after bag cutting is carried out.

[0003] However, at present, the moisture content of most molybdenum concentrates is higher than 10%, and the molybdenum concentrates inside the ton bag are easy to stick together. After the first bag cutting, the molybdenum concentrates in the ton bag cannot flow out effectively from the opening. It is necessary to cut the bag multiple times to expand the opening range of the ton bag before the material can be discharged normally. In addition, a large part of the molybdenum concentrate will stick to the inner bag of the ton bag, and it needs to be manually knocked before it can be discharged. The discharge effect of ton bag cutting needs to be further improved. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a new type of molybdenum concentrate ton bag cutter.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A novel molybdenum concentrate ton bag cutter comprises a mounting frame fixedly arranged in a molybdenum concentrate storage bin, the mounting frame is provided with a support and a plurality of buffer springs, one end of the support is provided with a cutting spike and a sliding sleeve is slidably matched with the support, the sliding sleeve is rotatably connected to at least one rotating shaft, the rotating shaft is provided with a cutting knife and a bent rotating rod, one end of the buffer spring is connected to a supporting plate, the supporting plate is provided with a through hole allowing the support to pass through, one end of the rotating rod is matched with the mounting frame and the rotating rod and the support are connected by a telescopic spring.

[0007] The device significantly improves the efficiency of cutting and unloading molybdenum concentrate in ton bags, can complete the cutting process at one time and effectively expand the opening range, and at the same time has a stirring effect on the materials inside the ton bag, thereby making the subsequent unloading smoother. In addition, it effectively reduces the labor intensity of multiple manual operations of cutting bags and does not require electricity or other power sources. It has stable and reliable operation and good use effect.

[0008] Furthermore, a roller is arranged at one end of the rotating rod, and a track matching with the roller is arranged on the mounting frame.

[0009] The above solution can accurately limit the movement trajectory of the rotating rod in the horizontal direction and effectively reduce the friction between the rotating rod and the mounting frame through the cooperation of the roller and the track.

[0010] Furthermore, a plurality of blanking holes are provided on the support plate.

[0011] Furthermore, a plurality of feeding holes are provided on the mounting frame.

[0012] The above scheme can reduce the probability of accumulation and residue of molybdenum concentrate on the support plate and the mounting frame during the subsequent unloading process after the ton bag is cut and the material is discharged by opening the drop hole and the unloading hole on the support plate and the mounting frame respectively.

[0013] Furthermore, the shape of the pillar is narrow at the top and wide at the bottom, and the size of the lower end is larger than the size of the through hole.

[0014] In the above solution, the shape of the pillar is set to be narrow at the top and wide at the bottom, which can further limit the movement range of the support plate, thereby controlling the movement range of the cutting knife to cut the bag.

The utility model is further described in combination with the drawings and embodiments:

[0023] like Figures 1 to 3 As shown, a novel molybdenum concentrate ton bag cutter comprises a mounting frame 1 fixedly mounted in a molybdenum concentrate storage bin, which is not shown in the figure. A support 2 and a plurality of buffer springs 11 are arranged on the mounting frame 1. A cutting spike 7 is arranged at one end of the support 2 and a sliding sleeve 3 is slidably matched on the support 2. The sliding sleeve 3 is rotatably connected to at least one rotating shaft 4, on which a cutting knife 6 and a bent rotating rod 5 are arranged. One end of the buffer spring 11 is connected to a support plate 12, on which a through hole 14 is provided for allowing the support 2 to pass through. One end of the rotating rod 5 is matched with the mounting frame 1 and the rotating rod 5 is connected to the support 2 via a telescopic spring 10.

[0024] Further refinement of the embodiment of the present utility model is as follows: Figure 1 As shown, a roller 8 is provided at one end of the rotating rod 5 , and a track 9 matched with the roller 8 is provided on the mounting frame 1 .

[0025] The workflow of this utility model:

[0026] First, hoist the ton bag so that the ton bag falls on the cutting thorn 7 to give it a support point and pierce the ton bag. The ton bag is shown as unnumbered in the figure. While piercing, the cutting knife 6 also enters the inside of the ton bag. When the ton bag contacts the support plate 12, the buffer spring 11 will be compressed immediately. Then the support plate 12 drops and contacts the rotating rod 5. At this time, a force will be given to the rotating rod 5 in the direction of the pillar 2. At this time, the telescopic spring 10 is compressed and the roller 8 moves from left to right along the track 9. While the rotating rod 5 moves, the sliding sleeve 3 moves up and the cutting knife 6 rotates counterclockwise to expand its cutting range. The instruction manual is attached Figure 1 Only one set of cutting knives 6 and rotating rods 5 are shown in the figure, which can further expand the size of the opening of the ton bag, and at the same time, can produce a stirring and scraping effect on the material inside the ton bag, thereby further improving its subsequent discharge effect. The movement range of the cutting knife 6 is expanded during the downward movement of the support plate 12, thereby effectively expanding the opening area of ​​the ton bag. After the bag is cut, the ton bag is immediately hoisted and moved up. When the cutting knife 6 and the cutting thorn 7 are away from the ton bag, the cutting knife 6, the rotating rod 5 and the sliding sleeve 3 are reset due to the action of the telescopic spring 10, and the material in the ton bag can be effectively discharged. No secondary bag cutting process is required, and the bag cutting effect is significantly improved.

[0027] Compared with the existing technology, the device significantly improves the efficiency of cutting and unloading molybdenum concentrate in ton bags, can complete the cutting process at one time and effectively expand the opening range, and at the same time has a stirring effect on the materials inside the ton bag, thereby making the subsequent unloading smoother. In addition, it effectively reduces the labor intensity of multiple manual operations of cutting bags and does not require electricity or other power sources. It runs stably and reliably and has good use effect.

[0028] In some embodiments, Figure 2 and Figure 3 As shown, a plurality of blanking holes 13 are provided on the support plate 12;

[0029] In a further optimization of the above embodiment, a plurality of discharge holes 15 are provided on the mounting frame 1; by respectively providing the discharge holes 13 and the discharge holes 15 on the support plate 12 and the mounting frame 1, the probability of accumulation and residue of molybdenum concentrate on the support plate 12 and the mounting frame 1 during the subsequent discharge process after the ton bag is cut and the bag is discharged can be reduced.

[0030] In other embodiments, Figure 1 As described above, the shape of the pillar 2 is narrow at the top and wide at the bottom, and the size of the lower end is larger than the size of the through hole 14; in this embodiment, the shape of the pillar 2 is set to be narrow at the top and wide at the bottom, which can further limit the movement range of the support plate 12, thereby controlling the movement range of the cutting knife 6 to cut the bag.
