Description

Technical Field

[0001] This utility model relates to the field of board production technology, and in particular to a feeding device for the production of magnesium oxide board. Background Technology

[0002] Magnesium oxide board is a new type of building material. Its production requires adding magnesium oxide from ton bags into a silo. Patent application number 202323582640.1 discloses a raw material feeding device for magnesium oxide board production. The feeding cylinder is detachably mounted on top of the material silo. An installation cavity is located within the side wall of the feeding cylinder. A bag-breaking mechanism slides vertically within the feeding cylinder. A reset component is located between the bag-breaking mechanism and the feeding cylinder. The bag-breaking mechanism can slide down due to the weight of the ton bag, and when it reaches the bottom, it can puncture the ton bag. A sealing plate slides near the top of the feeding cylinder. A transmission mechanism is located within the installation cavity and is connected to both the bag-breaking mechanism and the sealing plate. During feeding, the sealing plate can seal the top of the feeding cylinder, thus trapping the dust generated within the silo and preventing dust from harming the health of workers. However, its structure is relatively complex. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device for the production of magnesium oxide board in order to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a feeding device for the production of magnesium oxide board, including an installation cylinder, which is set at the top of the material silo, and a bag-breaking knife assembly is provided inside the installation cylinder. Grooves penetrating the cylinder wall are provided on both sides of the upper part of the installation cylinder, and first ear plates are provided on both sides of the lower part. A lifting cylinder is also slidably connected inside the installation cylinder, and second ear plates are provided on both sides of the lifting cylinder. A lifting drive device is provided between the first ear plates and the second ear plates, and a support plate is provided around the inner side of the top of the lifting cylinder.

[0005] Preferably, the bag-breaking knife assembly includes four bag-breaking knives, with one end of the four bag-breaking knives joined together. The projections of the four bag-breaking knives on the horizontal plane are perpendicular to each other. The four bag-breaking knives are inclined and the height of the one end where they are joined together is greater than the height of the other end.

[0006] Preferably, one end of the four bag-breaking knives that are joined together is provided with a bag-breaking cone with its tip pointing upwards.

[0007] Preferably, four support bars are provided below the bag-breaking knife assembly, and fixing plates are provided at the four corners inside the mounting cylinder, with the four support bars connected to the four fixing plates respectively.

[0008] Preferably, the four corners of the lower part of the lifting cylinder are provided with notches to avoid the fixing plate.

[0009] Preferably, the interior of the four walls of the lifting cylinder is provided with a support frame.

[0010] Compared with the prior art, the present invention has the following advantages: a bag-breaking knife assembly is provided inside the installation cylinder, the lifting cylinder is slidably connected to the installation cylinder, and a support plate is provided around the inner side of the top of the lifting cylinder so that the top of the lifting cylinder forms a feed inlet. After the lifting cylinder descends, the ton bag placed on the top of the lifting cylinder can be broken. Since the ton bag blocks the feed inlet, it is difficult for dust to fly out from the feed inlet. The structure of the present application is relatively simple. Attached Figure Description

[0015] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] Detailed implementation method: combined with Figure 1-3As shown, a feeding device for the production of magnesium oxide board includes an installation cylinder 1, preferably with a square cross-section. The installation cylinder 1 is located at the top of the material silo. A bag-breaking knife assembly 13 is installed inside the installation cylinder 1. Grooves 12 penetrating the cylinder wall are provided on both sides of the upper part of the installation cylinder 1, and first ear plates 11 are provided on both sides of the lower part. The first ear plates 11 are located outside the installation cylinder 1. A lifting cylinder 2 is also slidably connected inside the installation cylinder 1. Second ear plates 23 are provided on both sides of the lifting cylinder 2, and the second ear plates 23 are located directly above the first ear plates 11. A lifting drive device 3 is provided between the first ear plates 11 and the second ear plates 23. The lifting drive device 3 can be a pneumatic cylinder or a hydraulic cylinder. A support plate 21 is provided around the inner side of the top of the lifting cylinder 2, so that the top of the lifting cylinder 2 forms a feeding port. The side length of the feeding port is smaller than the side length of the bottom of the ton bag (the side length of the installation cylinder 1 is larger than the side length of the bottom of the ton bag). In use, the ton bag is lifted and placed on top of the lifting cylinder 2, blocking the feed inlet. Then, the lifting drive device 3 is operated to lower the lifting cylinder 2, and the bag-breaking knife group 13 cuts the bottom of the ton bag, allowing the material to fall. Because the ton bag blocks the feed inlet, it is difficult for dust to fly out from the feed inlet. After all the material has fallen, the lifting cylinder 2 is raised, and then the ton bag is removed for the next operation.

[0017] Specifically, the bag-breaking knife assembly 13 includes four bag-breaking knives, with one end of each knife joined together. The projections of the four knives on the horizontal plane are perpendicular to each other. The four knives are set at an angle, and the height of the joined end is greater than the height of the other end. This structure can cut a cross-shaped slit at the bottom of the ton bag, making it easier for the material to fall out.

[0018] Furthermore, one end of the four bag-breaking knives that are joined together is provided with a bag-breaking cone with its tip pointing upwards, making it easier to break the bag.

[0019] Furthermore, four support bars are provided below the bag-breaking knife assembly 13, and fixing plates are provided at the four corners inside the mounting cylinder 1. The four support bars are connected to the four fixing plates respectively, so as to fix the bag-breaking knife assembly 13 inside the mounting cylinder 1.

[0020] Furthermore, the four corners of the lower part of the lifting cylinder 2 are provided with notches 22 to avoid the fixing plate, so that the height of the support bar does not need to be too large.

[0021] Furthermore, each of the four walls of the lifting cylinder 2 is equipped with a support frame 24. Each support frame 24 has a very large gap with the bag-breaking knife assembly 13. As the material in the ton bag flows out, when the material inside becomes too low, the ton bag will collapse due to the lack of material support and will easily slide from the feed inlet into the lifting cylinder 2. The support frame 24 can support the bottom of the ton bag to prevent it from falling too far into the lifting cylinder 2.

[0022] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
