[0033] In the existing glass production, glass materials need to be fed into the kiln or feeder to carry out glass batching production. However, due to the height of the kiln and the feeder, it is not convenient to manually climb to cut and unload the material bags (such as ton bags). At the same time, the injected sodium carbonate and other materials are hygroscopic and easily absorb water and become hardened before feeding, resulting in the inability to feed smoothly after the material bag is cut, and manual crushing is required for feeding. In view of this situation, the present application has developed a discharging device suitable for agglomerated materials to overcome the problem of time-consuming and labor-intensive manual feeding.

[0034] This application Figures 1 to 6 An embodiment of the unloading device of the present application is schematically shown.

[0035] like Figures 1 to 6 As shown, the present application discloses a material unloading device, which includes: a support frame 1, on which a material bag is placed for feeding into a glass furnace or a feeding machine. A material storage tank 2, which is arranged on the support frame 1, the upper end of the material storage tank 2 is opened as a feeding port, and the lower end of the material storage tank 2 is opened as a leakage port, and a cutter 21 for cutting the material bag is arranged in the material storage tank 2. An extrusion assembly 3, which is arranged on the support frame 1 and is used to squeeze the material bag on the support frame 1 to realize the material feeding.

[0036] Through the above-mentioned structural design, the embodiment of the present application arranges a cutting knife 21 in the storage tank 2 so that it can automatically cut the material bag when the material bag is placed, and automatically extrude the material bag to realize powder with the help of the extrusion component 3, thereby eliminating the need for manpower to cut the material bag and manual powder, saving time and labor, and is particularly suitable for feeding powdered materials that are easy to agglomerate into glass kilns.

[0037] In some embodiments of the present application, Figure 2 As shown, the feeding port of the storage tank 2 is flush with the upper surface of the support frame 1, so that the material bag can be stably placed on the upper surface of the support frame 1 to achieve stable feeding. The tip of the cutting knife 21 in the storage tank 2 is higher than the feeding port, so that the material bag can be pierced when it is placed, so as to automatically cut the material bag open for discharge.

[0038] In some embodiments of the present application, Figure 2 As shown, the support frame 1 includes: legs 11 and a support surface 12 of the frame structure. A fixing opening for installing the storage tank 2 is reserved at the center of the support surface 12. The outer wall of the storage tank 2 fits in the fixing opening to achieve stable fixation. The extrusion component 3 is installed on the frame structure around the fixing opening to squeeze the material bag located above the storage tank 2, so that the material in the material bag is crushed and enters the storage tank 2 to achieve feeding. Figure 2 It can be seen that the material bag body is loaded by the support surface 12 of the frame structure, and the cutter 21 only needs to be slightly higher than the feeding port to scratch the material bag. The main load of the material bag is not on the cutter 21, and the cutter 21 will not be damaged by heavy pressure.

[0039] In some embodiments of the present application, Figure 3 and Figure 4 As shown, a cross-mounted cross bar 22 is provided in the material storage tank 2, and the cross bar 22 penetrates into the material storage tank 2 and is lower than the feeding port, so that the lower end of the cutter 21 is lower than the feeding port, reducing the load of the cutter 21 and preventing the cutter 21 from being deformed or broken by force. Multiple groups of cutters 21 are provided on the cross bar 22, and the multiple groups of cutters 21 are arranged facing each other and extending out of the feeding port in a tower shape, and the tower-shaped tip forms a knife tip, so that the bottom of the material bag is cut open by the weight of the material bag, so that the material falls into the material storage tank 2.

[0040] In the embodiments of the present application, Figure 3 and Figure 4 As shown, two crossbars 22 are arranged crosswise, and four sets of cutting knives 21 are arranged at the intersection of the two crossbars 22, and the four sets of cutting knives 21 are welded and arranged along the extending direction of the crossbars 22. The cutting knives 21 do not need to be particularly sharp, and in order to have a certain strength, 1-5mm steel plates can be used for welding, and the tips can be appropriately sharpened.

[0041] In some embodiments of the present application, Figure 3As shown, a flange 23 is provided at the lower end of the material storage tank 2 at the material leakage port, and a docking flange 24 is connected below the flange 23. The docking flange 24 can be used to achieve a soft connection with a feeder to facilitate the transportation of materials.

[0042] In some embodiments of the present application, Figure 5 As shown, a filter screen 25 may be provided between the flange 23 and the docking flange 24 of the storage tank 2. The filter screen 25 is used to screen the particle size of the material entering the feeder to prevent excessively large material blocks from entering the feeder, causing poor feeding and affecting production. In addition, in some embodiments of the present application, the filter screen 25 preferably adopts a magnetic filter screen 25. The magnetic filter screen 25 can absorb iron filings mixed in the material (carried by the material itself or shed by the equipment) to filter the feed and protect the safety of the production equipment. Figure 5 As shown, the filter screen 25 has a mesh frame and a woven mesh covered on the mesh frame. In some embodiments of the present application, the filter screen 25 is an iron mesh, and the iron mesh is used through magnetization.

[0043] In some embodiments of the present application, Figure 3 As shown, a vibration hammer 26 is also provided on the outer side of the storage tank 2. The vibration hammer 26 is used to hammer the outer wall of the storage tank 2 when necessary, so that the material in the storage tank 2 is further broken up and falls, so that the material can fully enter.

[0044] In some embodiments of the present application, Figure 1 As shown, the extrusion assembly 3 includes four groups, and the four groups of extrusion assemblies 3 are respectively arranged above the four sides of the support frame 1, and are arranged in pairs facing each other and vertically. In the embodiment of the present application, the extrusion assembly 3 includes two pairs of vertically arranged extrusion assemblies 3, and the two pairs of extrusion assemblies 3 work alternately to extrude the material bag in a single line from two vertical directions respectively, so as to avoid further compression and agglomeration when the material bag is squeezed on all sides at the same time, which is not conducive to crushing. The extrusion assemblies 3 in the embodiment of the present application adopt alternating extrusion in groups of two, so that the material in the material bag can be fully crushed and easy to unload. At the same time, in this embodiment, the position of the extrusion assemblies 3 around the support frame 1 should be close to the size of the material bag, and at the same time play the role of supporting the material bag from the side, so as to fix the material bag on the support frame 1 and prevent the material bag from shaking on the support frame 1.

[0045] In some embodiments of the present application, Figure 6 As shown, each extrusion assembly 3 has the same structure, and includes: an extrusion plate 31, a cylinder 32 and a push rod 33. The cylinder 32 is connected to the push rod 33, and the push rod 33 is connected to the extrusion plate 31. The cylinder 32 drives the extrusion plate 31 to reciprocate through the push rod 33. Among them, the cylinders 32 of a pair of extrusion assemblies 3 arranged opposite to each other are arranged in linkage to achieve single-time single-line opposite extrusion crushing.

[0046] In some embodiments of the present application, Figure 6As shown, the extrusion plate 31 is an arc-shaped extrusion plate 31 with a curvature. The curvature refers to the protrusion in the center of the extrusion plate 31, and the smooth transition and recovery on both sides. Through this structural design, each time the extrusion plates 31 of a pair of extrusion assemblies 3 squeeze the material bag towards each other, the material in the material bag will move to both sides and be crushed, and it is not easy to be compressed and agglomerated, thereby ensuring the extrusion and crushing effect.

[0047] In some embodiments of the present application, Figure 6 As shown, the back of the extrusion plate 31 is also provided with a reinforcing rib 311, which can strengthen the strength of the extrusion plate 31, resist deformation, and improve the extrusion effect and the service life of the extrusion plate 31. At the same time, the reinforcing rib 311 can also be used to assist in fixing the push rod 33. For example, the reinforcing rib 311 is arranged around the top block of the push rod 33 to form a slot to limit the movement of the top block, so as to assist in improving the fixing stability of the push rod 33.

[0048] Combination Figures 1 to 6 As shown, the working principle of the unloading device of this application is explained:

[0049] First, place the unloading device at the entrance of the glass kiln or above the feeder, and connect the kiln entrance or the feeder feed port through the docking flange 24. Then, use a crane or electric hoist to lift the ton bag to a certain height, and then slowly put it on the support frame 1. The extrusion assembly 3 assists in supporting the ton bag from all sides to prevent the ton bag from shaking. When the bottom of the ton bag contacts the cutter 21, due to the weight of the ton bag, the bottom of the ton bag is cut by the sharp tip of the cutter 21, and the material falls into the storage tank 2. When the material is agglomerated, the extrusion assemblies 3 are grouped together in pairs. For example, the front and rear extrusion assemblies 3 move toward each other to extrude the ton bag, so that the material in the ton bag is squeezed and dispersed, and then the extrusion assemblies 3 on the left and right sides move toward each other to extrude the ton bag. This cycle is repeated, so that the material in the ton bag is broken and falls into the storage tank 2. In order to prevent the material from being too large after being crushed by the upper extrusion assembly 3, a filter screen 25 is installed at the bottom of the storage tank 2. The filter screen 25 can be magnetized to absorb iron filings in the material. On the other hand, the diameter of the material block falling into the feeder can be controlled by changing the gap size of the filter screen 25 during the production process to meet the production requirements of different batches. In addition, the oversized material block is further hammered down by the vibration hammer 26. Specifically, the vibration hammer 26 hammers the outer wall of the storage tank 2, causing the material to vibrate and loosen and fall into the feeder.

[0050] In summary, the unloading device of the present application includes: a support frame, a storage tank and an extrusion assembly, a material bag is placed on the support frame; the storage tank is arranged on the support frame, the upper end of the storage tank is opened as a feeding port, the lower end of the storage tank is opened as a leakage port, and a cutter for cutting the material bag is arranged in the storage tank; the extrusion assembly is arranged on the support frame, and is used to squeeze the material bag on the support frame. The present application arranges a cutter in the storage tank so that the material bag can be cut open by itself when the material bag is placed, and the material bag is automatically squeezed by the extrusion assembly to realize powder material, thereby eliminating the need for manpower to cut the material bag and manual powder material, saving time and labor, and is particularly suitable for feeding easy-to-cake powder materials in glass kilns.
