Description

Technical Field

[0001] The present application relates to the technical field of material unpacking, and in particular to a bag-breaking ton bag unpacking device. Background Art

[0002] A bag unpacker is a machine used to break up ton bags. Currently, semi-automatic unpacking is commonly used for ton bags. Semi-automatic unpacking uses an overhead crane electric hoist or a forklift to transport the materials to the designated loading area, and then uses the overhead crane electric hoist of the semi-automatic bag unpacker to lift the materials and transport them to the feeding bin. The manual button closes the hatch, and the operator operates the electric hoist to lower the ton bag, breaking the bottom of the ton bag for the materials to flow out. After the materials have flowed out, the manual button opens the hatch, and the overhead crane lifts out the waste empty bags, which are manually removed and sent to the waste bag area.

[0003] In the prior art, when breaking open a ton bag, the weight of the ton bag is generally used to press on the blade, and the blade cuts the ton bag. In this method, the blade is fixed and cannot move, and there is a disadvantage that the rupture of the ton bag cannot be expanded, which affects the unloading speed of the ton bag. At the same time, if the rupture is small, there will be more residual materials after unpacking, resulting in certain waste. Utility Model Content

[0004] The purpose of this application is to provide a bag-breaking ton bag unpacking device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present application provides a bag-breaking ton bag unpacking device adopting the following technical solutions:

[0006] The bag-breaking device comprises a bag-breaking device, comprising a support, a gantry crane mechanism installed on the support, and a bag-breaking box installed in the support, wherein a double-opening door is provided on one side of the bag-breaking box, and the bag-breaking box comprises an upper feeding bin and a lower unloading bin which are connected in sequence. The double-opening door is arranged on the front side of the upper feeding bin, and a give groove is opened on the top of the upper feeding bin, and the gantry crane mechanism can transport the ton bag into the upper feeding bin through the give groove, and the lower unloading bin is provided with a bag-breaking mechanism.

[0007] A dust hood is installed on the rear side wall of the upper feed bin, and a plurality of dust exhaust grilles are opened on the rear side wall of the upper feed bin.

[0008] Preferably, cylinders are symmetrically fixed on both sides of the bottom of the upper feed bin near the lower discharge bin, the piston rods of the cylinders extend into the upper feed bin, and push plates are fixed at the ends of the cylinder piston rods, which can beat the ton bags.

[0009] Preferably, the lower unloading bin includes a material storage section and a material discharge section that are connected to each other. The material discharge section is funnel-shaped, and a valve is connected to the bottom of the material discharge section.

[0010] An automatic door opener is symmetrically installed in the upper feeding bin, and the automatic door opener is connected to the door body of the bi-directional door.

[0011] Preferably, in order to reduce dust overflow from the clearance groove, a soft pad is fixed on the side of the clearance groove.

[0012] The hammer is a straight pneumatic hammer, and a rubber pad is fixed to the bottom of the support rod.

[0013] To sum up, the present application includes at least one of the following beneficial technical effects: the bag-breaking ton bag unpacking device is configured to be movable through the bag-breaking knife holder. When the ton bag is pressed down in the initial position, it is in a stationary state, so that the ton bag can be broken. Then, a hammer is used to apply a hammering force to the bag-breaking knife holder from the bottom of the support rod, so that the break can be enlarged, thereby increasing the unloading speed and not easily leaving residual materials.

[0017] The following is combined with Figure 1-2 This application is described in further detail.

[0018] The present application discloses a bag-breaking ton bag unpacking device, referring to Figure 1-2, including a bracket 1, a truss lifting mechanism 2 installed on the bracket 1, and a bag breaking box installed in the bracket 1. A double-door 31 is provided on one side of the bag breaking box. The bag breaking box includes an upper feeding bin 3 and a lower unloading bin 4 connected in sequence. The double-door 31 is provided on the front side of the upper feeding bin 3. An automatic door opener is symmetrically installed in the upper feeding bin 3. The automatic door opener is connected to the door body of the double-door 31. A clearance groove 32 is provided on the top of the upper feeding bin 3. The truss lifting mechanism 2 can transport the ton bag to the upper feeding bin 3 through the clearance groove 32. A cushion is fixed on the side of the clearance groove 32. The lower unloading bin 4 A bag breaking mechanism is provided inside, which includes a bag breaking knife holder 5. The orthographic projection of the bag breaking knife holder 5 is in the shape of a three-pointed star. A plurality of cutting knives are evenly and obliquely fixed on the bag breaking knife holder 5. Support rods 51 are symmetrically fixed on both sides of the bottom of the bag breaking knife holder 5. The bottom of the support rod 51 passes through the lower unloading bin 4. A stop block 511 is fixed to the side of the support rod 51. The stop block 511 can abut against the bracket 1. A hammer 6 is provided at the bottom of the support rod 51. The hammer 6 is fixed on the bracket 1 and can hammer the support rod 51. The hammer 6 is a straight pneumatic hammer. A rubber pad is fixed to the bottom of the support rod 51.

[0019] The lower unloading bin 4 includes a storage section 41 and a discharge section 42 which are connected to each other. The discharge section 42 is funnel-shaped and a valve is connected to the bottom of the discharge section 42.

[0020] In order to reduce dust pollution, a dust hood 8 is installed on the rear side wall of the upper feed bin 3 , and a plurality of dust exhaust grilles 33 are opened on the rear side wall of the upper feed bin 3 .

[0021] Reference Figure 2 Cylinders 7 are symmetrically fixed on both sides of the bottom of the upper feed bin 3 near the lower unloading bin 4. The piston rod of the cylinder 7 extends into the upper feed bin 3. A push piece 71 is fixed to the end of the piston rod of the cylinder 7, and the push piece 71 can beat the ton bag.

[0022] By arranging the cylinder 7 and utilizing the cylinder 7 to drive the push piece 71 to beat the ton bag, the outflow of the material can be accelerated and the residual material on the ton bag can be reduced.

[0023] The implementation principle of the bag-breaking ton bag unpacking device in the embodiment of the present application is as follows:

[0024] The ton bag is hoisted into the upper feeding bin 3 by the gantry hoist mechanism 2, and the double-door 31 is closed. The gantry hoist mechanism 2 lowers the ton bag into the middle bag breaking bin. Under the action of the ton bag's own weight, the ton bag contacts the bag breaking knife holder 5. The cutting knife on the bag breaking knife holder 5 breaks the bottom of the ton bag. The rear hammer 6 hammers the support rod 51. The support rod 51 is hammered and transmits the force to the bag breaking knife holder 5. The bag breaking knife holder 5 drives the cutting knife upward, thereby widening the opening and increasing the unloading speed. The enlarged bag opening is not easy to cause residual materials.

[0025] The lower discharge bin 4 is provided with a storage section 41, which can realize the storage function and enable the continuous feeding of ton bags.

[0026] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
