Description

Technical Field

[0001] The present application relates to the technical field of material unloading, and in particular to a material unloading device capable of automatically changing buckets. Background Art

[0002] The unloading device is used to unload materials into packaging bags or boxes. Due to the different products being unloaded, some special materials, such as sticky materials, will have material residues remaining on the hopper of the unloading device after a certain number of unloading processes, resulting in a slow unloading speed. Therefore, the hopper needs to be replaced for cleaning before continued use. If the machine is stopped for replacement of the hopper, it will affect production efficiency. In particular, frequent replacement greatly wastes labor and increases production costs. Utility Model Content

[0003] The purpose of the present application is to provide a material discharging device capable of automatically changing buckets, so as to solve the problem that the material discharging buckets of existing material discharging devices cannot be automatically replaced without stopping the machine.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a material unloading device with automatic bucket change, comprising a frame, a material unloading mechanism and a limit bag supporting mechanism, the limit bag supporting mechanism is rotatably connected to the frame, the material unloading mechanism comprises a material unloading hopper and a turntable assembly, the turntable assembly comprises an upper disc, the bottom end of the upper disc is connected to the frame through a connecting column, the upper disc is rotatably connected to the connecting column, a plurality of sliding columns are connected to the upper disc, the material unloading hopper is slidably connected between two sliding columns, the material unloading hopper can slide up and down along the sliding columns, and the limit bag supporting mechanism limits the position of the material unloading hopper during unloading.

[0005] During normal unloading, the limit bag support mechanism limits the unloading hopper. When the unloading hopper needs to be replaced, the limit bag support mechanism rotates away from the unloading hopper. After the unloading hopper slides upward along the sliding column, the upper disc rotates to rotate the other unloading hopper above the unloading position. The new unloading hopper slides downward along the sliding column to the unloading position, and the limit bag support mechanism rotates back to limit the new unloading hopper. Therefore, the unloading device that can automatically change the hopper can automatically change the hopper according to the characteristics of different materials, at a fixed time or according to the number of unloading times, without stopping the machine, which is convenient and fast.

[0006] Preferably, the discharge port of the discharge hopper has an adjustable diameter, which facilitates and facilitates rapid discharge of materials.

[0007] Preferably, the position-limiting bag-supporting mechanism comprises a driving rod, one end of which is connected to a motor, and the motor drives the driving rod to rotate. The position-limiting bag-supporting mechanism limits the position of the material hopper during material discharge to prevent the material hopper from rotating.

[0008] Preferably, a slot is provided at the end of the driving rod away from the motor, and two rotating rods are connected in the slot, and the rotating rod is vertically arranged to the driving rod. The two rotating rods are respectively connected to support plates at one end away from the slot, and the support plates are vertically arranged to the rotating rod. Before the packaging bag reaches the discharge port of the lower hopper, the two support plates are close to each other. After the packaging bag arrives, the two support plates are placed in the packaging bag. At this time, the rotating rod rotates to move the two support plates away from each other to open the packaging bag, which is convenient for loading materials.

[0009] Preferably, the discharge hopper includes two fan-shaped discharge hopper pieces, both of which are arc-shaped structures. The two fan-shaped discharge hopper pieces are connected by elastic parts to form the discharge hopper. A discharge cylinder is connected to the frame, and a discharge piston is connected to the bottom end of the discharge cylinder. When discharge, the discharge piston enters the discharge hopper to expand the elastic parts of the two fan-shaped discharge hopper pieces, so that the discharge port of the discharge hopper becomes larger, which is convenient and quick to discharge. After the discharge is completed, the discharge piston leaves the discharge hopper, the elastic part rebounds, and the discharge port of the discharge hopper shrinks.

[0010] Preferably, the discharge piston is a solid structure.

[0011] Compared with the prior art, the beneficial effect of the present application is that the unloading device with automatic bucket change can, according to the characteristics of different materials, rotate the turntable assembly at a fixed time or according to the number of unloading times to remove the dirty unloading bucket, and another clean hopper is rotated to the unloading position and limited, thereby realizing automatic bucket change without stopping the machine, which is convenient and quick.

Obviously, the described embodiments are only 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 are within the scope of protection of this application.

[0018] Embodiment 1

[0019] like Figure 1 and 2 As shown, a material unloading device with automatic bucket change comprises: a frame 1, a material unloading mechanism and a position-limiting bag-supporting mechanism. The position-limiting bag-supporting mechanism is rotatably connected to the frame 1. The position-limiting bag-supporting mechanism limits the position of the material unloading mechanism during material unloading and simultaneously opens the bag mouth of the packaging bag to facilitate material unloading.

[0020] The material discharging mechanism includes a discharging hopper 2 and a turntable assembly 3. Figure 4 As shown, the turntable assembly 3 includes an upper disc 31, the bottom end of the upper disc 31 is connected to the frame 1 through a connecting column, the upper disc 31 is rotatably connected to the connecting column, and a plurality of sliding columns 32 are connected to the upper disc 31. The lower hopper 2 is slidably connected between the two sliding columns 32, and the lower hopper 2 can slide up and down along the sliding columns 32. The limit bag support mechanism limits the lower hopper 2 when unloading. When the hopper needs to be changed, the limit bag support mechanism rotates away from the lower hopper, and the lower hopper moves upward for a distance. The upper disc 31 rotates to rotate the clean lower hopper to above the unloading position. The clean lower hopper moves down to the unloading position, and the limit bag support mechanism is reset, and continues to limit the lower hopper 2 when unloading to prevent the lower hopper from rotating when unloading.

[0021] The limit bag support mechanism includes a driving rod 4, one end of which is connected to a motor, and the motor drives the driving rod 4 to rotate. Figure 3 As shown, a slot 41 is provided at one end of the driving rod 4 away from the motor, and two rotating rods 5 are connected in the slot 41. The rotating rod 5 is vertically arranged to the driving rod 4. The two rotating rods 5 are respectively connected to support pieces 51 at one end away from the slot. The support pieces 51 are vertically arranged to the rotating rods 5. When unloading, the driving rod 4 stops at both sides of the unloading hopper 2, and the two rotating rods 5 limit the unloading hopper 2. After the packaging bag reaches the unloading port, the rotating rod 5 separates the support pieces 51 to open the packaging bag.

[0022] The discharge hopper 2 includes two fan-shaped discharge hopper pieces, both of which are arc-shaped structures. The two fan-shaped discharge hopper pieces are connected by elastic parts to form a discharge hopper. The frame 1 is connected to a discharge cylinder 6, and the bottom end of the discharge cylinder 6 is connected to a discharge piston. When discharging, the discharge piston enters the discharge hopper 2, and the elastic part between the two fan-shaped discharge hopper pieces is stretched to enlarge the discharge port. After discharging, the discharge piston is lifted, and the elastic part rebounds to shrink the discharge port.
