[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0034] like Figure 1-Figure 7 As shown:

[0035] A box feeder provided in an embodiment of the present application includes a frame 1 , on which a material box 2 and a belt conveyor 16 are mounted, and the belt conveyor 16 is located below the material box 2 .

[0036] Specifically, the material box 2 is a hollow structure that penetrates from top to bottom, and the material box 2 is welded and fixed on the frame 1 .

[0037] The bottoms of the two long side ends of the material box 2 and the bottom of one short side end of the material box 2 are both rotatably connected with mounting bars 3.

[0038] Each of the mounting bars 3 is fixedly connected to a rubber plate 6 via a plurality of bolts 4 and nuts 5 located below the material box 2 , and a clamping structure 14 is provided on the side of each of the mounting bars 3 .

[0039] After the rubber sheet 6 is vertically distributed, the pressing structure 14 and the outer wall of the material box 2 can press the mounting bar 3 tightly, and the rubber sheet 6 abuts against the conveying belt 163 of the belt conveyor 16 .

[0040] In this embodiment, the left end, the front end and the rear end of the material box 2 are all provided with rubber plates 6 , and the right end of the material box 2 is the discharge end of the belt conveyor device 16 .

[0041] When in use, the powdered raw materials are transported from the top of the material box 2 into the material box 2. After the powdered raw materials enter the material box 2, they are accumulated on the belt conveyor 16. Then the belt conveyor 16 is started. The belt conveyor 16 transports the powdered raw materials to the processing equipment of the next process for feeding.

[0042] When the rubber sheet 6 needs to be replaced, first release the restriction of the clamping structure 14 on the mounting strip 3, then rotate the mounting strip 3 so that the bolts 4 on the mounting strip 3 are located on the side of the material box 2, then you can directly stand on the side of the material box 2 to disassemble and assemble the bolts 4 and replace the rubber sheet 6. After the replacement is completed, the rubber sheet 6 is then rotated to be vertically distributed, and the mounting strip 3 is directly pressed by the clamping structure 14 and the material box 2.

[0043] The box feeder provided in this embodiment is connected with a rotatable mounting bar 3 through the bottom of the left end, the bottom of the front end and the bottom of the rear end of the material box 2. Each mounting bar 3 is fixedly connected with a rubber plate 6 through a plurality of bolts 4 and nuts 5 located below the material box 2. A clamping structure 14 is provided on the side of each mounting bar 3. After the rubber plate 6 is vertically distributed, the clamping structure 14 and the outer wall of the material box 2 can press the mounting bar 3 tightly, and the rubber plate 6 abuts against the conveying belt 163 of the belt conveyor 16, so that when the rubber plate 6 is replaced, the entire bolt 4 can be moved to the side of the material box 2. Therefore, it is not necessary for the staff to enter the material box 2 to disassemble and assemble the bolt 4. It is only necessary to stand on the side of the material box 2, so that it is convenient to replace the rubber plate 6, which solves the problem of complicated operation, time-consuming and labor-intensive when replacing the rubber plate 6. Moreover, when the conveying belt 163 of the belt conveyor is replaced at a later stage, the abutment of the rubber plate 6 on the conveying belt 163 can be quickly released, which is convenient for replacing the conveying belt 163.

[0044] In some embodiments of the present application, the mounting bar 3 is an inverted L-shaped structure, and the upper end of the horizontal section of the mounting bar 3 is rotatably connected to the outer wall of the material box 2 through a hinge structure.

[0045] The rubber sheet 6 is fixedly connected to the vertical end of the mounting bar 3 by means of the bolt 4 and the nut 5. Specifically, the bolt 4 penetrates the rubber sheet 6 and the mounting bar 3, and the head of the bolt 4 and the nut 5 tightly press the rubber sheet 6 and the mounting bar 3. The rubber sheet 6 abuts against the horizontal section of the mounting bar 3.

[0046] In this embodiment, after the rubber sheet 6 is distributed vertically, the rubber sheet 6 contacts the outer wall of the material box 2 to improve the effect of preventing material leakage.

[0047] In some embodiments of the present application, the clamping structure 14 includes a screw rod 141, the number of the screw rods 141 is not less than two and they are horizontally distributed, a knob 142 is fixed to one end of the screw rod 141, an internal threaded sleeve 143 is sleeved on the screw rod 141 and meshedly connected thereto, and the internal threaded sleeve 143 is fixed to the frame 1.

[0048] In this embodiment, the number of screw rods 141 of the pressing structure 14 located at the left end of the material box 2 is two. The number of screw rods 141 of the pressing structure 14 located at the front end and the rear end of the material box 2 is three. The screw rod 141 is located between two adjacent bolts 4.

[0049] When in use, the screw rod 141 is rotated by the knob 142. After the screw rod 141 is rotated, the screw rod 141 moves toward the direction close to the mounting strip 3. When the mounting strip 3 is pressed tightly between the screw rod 141 and the wall of the material box 2, the rubber sheet 6 is vertically distributed, and one side end of the rubber sheet 6 contacts the wall of the material box 2. The lower end of the rubber sheet 6 abuts against the conveying belt 163, and the rubber sheet 6 performs the material blocking work.

[0050] In this embodiment, by providing the screw rod 141, it can not only be used to press the mounting strip 3 and limit the mounting strip 3, but also when disassembling the bolt 4, the rubber sheet 6 can be placed on the screw rod 141. The screw rod 141 supports the rotated rubber sheet 6 and the mounting strip 3, thereby further improving the convenience of disassembling the bolt 4.

[0051] In order to improve the pressing effect of the screw rod 141 on the installation bar 3 , in some embodiments of the present application, a circular pressing plate 144 is fixed to the other end of the screw rod 141 , and a rubber pad 145 for pressing the installation bar 3 is fixed to the pressing plate 144 .

The drive shaft 10 also includes two limit plates 101, and the two supports 12 are located between the two limit plates 101, and each limit plate 101 contacts the support 12 located on the same side as it to prevent the drive shaft 10 from moving in the axial direction.

[0054] When in use, the box door 7 can be moved up and down by turning the handle 13, so that the discharge amount can be adjusted, that is, the feeding amount of the belt conveyor device 16 can be adjusted.

[0055] In some embodiments of the present application, a crushing structure 15 is provided inside the material box 2 and is rotatable and close to the box door 7 .

[0056] In this embodiment, the crushing structure 15 includes a rotating shaft 151, which is rotatably connected to the front and rear ends of the material box 2. A plurality of crushing blades 152 located in the material box 2 are fixed on the rotating shaft 151. One end of the rotating shaft 151 extends out of the material box 2 and is connected to a first motor 153. The first motor 153 is fixed on the outer wall of the material box 2.

[0057] When in use, the motor drives the rotating shaft 151 to rotate, and the rotating shaft 151 drives the multiple crushing blades 152 to rotate, breaking up the agglomerated large pieces of powdery raw materials, so as to improve the uniform feeding effect of the belt conveyor 16.

[0058] In some embodiments of the present application, the belt conveyor 16 includes an active roller 161 and a driven roller 162, and the active roller 161 and the driven roller 162 are both rotatably connected to the frame 1, and a conveying belt 163 with an annular structure is connected between the active roller 161 and the driven roller 162, and the active roller 161 is connected to a driving mechanism that can drive it to rotate.

[0059] A plurality of rotatable rollers 164 are mounted on the frame 1 , and all of the rollers 164 are in contact with the upper and lower ends of the conveyor belt 163 at the same time.

[0060] When in use, the driving structure drives the active roller 161 to rotate. After the active roller 161 rotates, it drives the conveying belt 163 to move. The conveying belt 163 drives the powdered raw materials on its upper end to move, and the powdered raw materials are transported to the next processing equipment.

[0061] In some embodiments of the present application, the driving mechanism includes a second motor 165, which is connected to a reducer 166 through a transmission mechanism, and the reducer 166 is connected to the active roller 161. The second motor 165 drives the active roller 161 to rotate slowly through the reducer 166.

[0062] The second motor 165 and the reducer 166 are both fixed on the frame 1 .

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
