Description

A screw conveyor cutter roller unpacking machine Technical Field

[0001] This utility model belongs to the field of unpacking machines, specifically relating to an auger cutter roller unpacking machine. Background Technology

[0002] Packaging unpacking machines are mainly used for unpacking various bagged products. Previously, semi-automatic unpacking machines were primarily used, requiring manual control of the unpacking and unloading processes. This necessitated teamwork and resulted in high labor intensity, low efficiency, and potential for injury and environmental pollution. Furthermore, these machines were sometimes used to unpack products with pungent odors, such as urea fertilizers, which could cause occupational diseases due to close contact with the human body. Later, several newer types of packaging unpacking machines were developed, such as spiral unpacking machines, multi-blade unpacking machines, and saw blade unpacking machines.

[0003] In existing unpacking machines, the bags need to be transported to the cutting mechanism via a conveying mechanism to cut the bags, and then the material inside the bags is discharged via a shaking mechanism. Finally, the bags are transported to the waste bag collection mechanism for collection. Since each step is performed separately, the total unpacking time for a single bag is long and the unpacking efficiency is low. Summary of the Invention

[0004] In view of the problems in the prior art, this utility model provides a screw conveyor cutter roller unpacking machine to solve the problems in the prior art.

[0005] To achieve the above technical objectives, the technical solution of this utility model is as follows:

[0006] A screw conveyor cutting roller unpacking machine includes a machine housing, which houses a cylinder, a material collection mechanism, and a waste bag collection mechanism. The cylinder is arranged horizontally, and its bottom has several material discharge holes. A bag inlet is provided on one circumferential side of the cylinder. The machine housing has a bag opening adapted to the bag inlet. A cutting screw conveyor is rotatably arranged inside the cylinder, and the circumferential side of the cutting screw conveyor is provided with a cutting edge.

[0007] The material collection mechanism is located at the bottom of the cylinder and is used to collect falling materials;

[0008] The waste bag collection mechanism is located at the tail of the cylinder and is used to collect material bags.

[0009] The cylinder includes a grid cylinder and a drum screen. The drum screen is located at the tail of the grid cylinder. The bag feed inlet is located on the grid cylinder. Several material discharge holes are provided at the bottom of the grid cylinder and around the drum screen. A drive assembly for driving the drum screen to rotate is provided on the chassis.

[0010] The drive assembly includes a motor, a drive shaft, and a multi-wedge belt. The multi-wedge belt is sleeved around the circumference of the drum screen. The drive shaft is mounted on the machine housing. The motor is used to drive the drive shaft to rotate, thereby causing the multi-wedge belt to rotate.

[0011] The machine casing is provided with a number of passive rollers that rotate around it. The multi-wedge belt is located at one end of the drum screen, and the other end of the drum screen is located on the number of passive rollers.

[0012] The material collection mechanism includes a material collection cylinder, which is located below the grid cylinder and the drum screen.

[0013] The material collection cylinder is equipped with a rotating material collection screw conveyor.

[0014] The top of the material collection cylinder is provided with a discharge hopper, which is funnel-shaped.

[0015] The waste bag collection mechanism includes a waste bag collection cylinder, which is located below the end of the drum screen away from the grid cylinder.

[0016] The waste bag collection cylinder is equipped with a waste bag spiral auger.

[0017] The machine casing is equipped with a feeding conveyor mechanism at the bag opening.

[0018] The above-described structure of this utility model can achieve the following beneficial effects:

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0025] The present application will be further described in detail below with reference to Figures 1-2.

[0026] Referring to Figure 1, a screw conveyor cutter roller unpacking machine includes a machine housing, a cylinder, a material collection mechanism, and a waste bag collection mechanism. The bottom of the cylinder has several material discharge holes, and a bag inlet is provided on one circumferential side of the cylinder. The machine housing has a bag opening adapted to the bag inlet. A screw conveyor 1 is rotatably installed inside the cylinder, and the circumferential side of the screw conveyor 1 is provided with a cutting edge.

[0027] The material collection mechanism is located at the bottom of the cylinder and is used to collect falling materials;

[0028] The waste bag collection mechanism is located at the rear of the cylinder and is used to collect material bags;

[0029] The cylinder is set horizontally, and it can be set horizontally or tilted downwards toward one side of the waste bag collection mechanism.

[0030] Based on the above structure, the bag enters the cylinder through the bag inlet. Inside the cylinder, the bag is cut open by the blades on the side of the rotating cutter auger 1. The cut bag undergoes its first separation under the action of the rotating cutter auger 1. The separated material is collected in the material collection mechanism through the discharge hole and then transported outside the machine box. The waste bag falls into the waste bag collection mechanism from the tail of the cylinder and is finally transported outside the machine box. In this device, bag cutting, feeding, and waste bag transportation are all integrated and carried out simultaneously in the cylinder, allowing for uninterrupted bag unpacking. Furthermore, all process steps are integrated into the cylinder, resulting in a compact overall structure and small size.

[0031] As shown in Figure 1, the cylinder includes a grid cylinder 2 and a drum screen 3. The drum screen 3 is located at the tail end of the grid cylinder 2, and the bag feed inlet is located on the grid cylinder 2. Several discharge holes are provided at the bottom of the fixed cylinder 2 and circumferentially on the drum screen 3. A drive assembly for rotating the drum screen 3 is provided on the housing. The drive assembly includes a motor, a drive shaft 4, and a multi-wedge belt 5. The multi-wedge belt 5 is fitted around the drum screen 3 circumferentially. The drive shaft 4 is located on the housing, and the motor drives the drive shaft 4 to rotate, thereby causing the multi-wedge belt 5 to rotate. Several driven rollers 6 are rotatably arranged on the housing. The multi-wedge belt 5 is located at one end of the drum screen 3, and the other end of the drum screen 3 is located on the driven rollers 6 (for example, a set of symmetrically installed driven rollers 6, with the drum screen 3 positioned between the driven rollers 6). The bags entering the grid cylinder 2 are shuffled by the rotating cutter. The auger 1 breaks open the packaging bag. The cut bag is then separated for the first time by the rotating auger 1. The separated material is collected in the material collection mechanism. The packaging bag and any remaining material inside are pushed into the moving drum 3 by the auger 1. The drum screen 3 is driven to rotate by a drive mechanism consisting of a motor, drive shaft 4, and multiple wedge belts. The packaging bag and any remaining material inside are then separated a second time by the drum screen 3. The separated material is also collected in the material collection mechanism. The separated bags are then transported to the waste bag collection mechanism by the drum screen 3 for collection (a guide plate can be installed inside the drum screen 3 to guide the bag, for example, a spirally extended guide plate. When the drum screen 2 rotates, the packaging bag is guided to one end close to the waste bag collection mechanism).

[0032] As shown in Figures 1 and 2, the material collection mechanism includes a material collection cylinder 7, which is located below the grid cylinder 2 and the drum screen 3. A hopper 9 is provided at the top of the material collection cylinder 7, and the hopper 9 is funnel-shaped. A material collecting screw 8 is rotatably installed inside the material collection cylinder 7. In this way, the material falls from the bottom of the cylinder, is collected by the hopper 9, and enters the material collection cylinder 7. Then, the rotating material collecting screw 8 rotates and discharges the material from the machine box.

[0033] As shown in Figures 1 and 2, the waste bag collection mechanism includes a waste bag collection cylinder 10, which is located below the end of the drum screen 3 away from the grid cylinder 2. The waste bag collection cylinder 10 has an upward opening, and a waste bag spiral auger 11 is installed inside the waste bag collection cylinder 10. The waste bags fall from the tail of the drum screen 3 and enter the waste bag collection cylinder 10. After being rotated by the waste bag spiral auger 11, they are conveyed out of the machine box.

[0034] As shown in Figure 2, the machine is equipped with a feeding conveyor 12 at the bag opening. For some working conditions that require manual feeding of bags into the machine, the feeding conveyor 12 (e.g., a conveyor belt) can be set outside the machine. Simply place the bag to be unpacked on the feeding conveyor 12, and the bag will be conveyed into the grid cylinder 2. Then the equipment will automatically perform a series of subsequent unpacking actions.

[0035] In summary, the bags are conveyed from the unpacking machine's inlet into the grid cylinder 2 via the feeding conveyor 12. Inside the grid cylinder 2, the bags are cut open by the rotating cutting auger 1. The cut bags undergo their first separation under the action of the rotating cutting auger 1. The separated material flows through the discharge hole into the discharge hopper 9. The incompletely separated material and bags are then conveyed by the cutting auger 1 to the rotating drum screen 3 for a second separation. The separated material falls into the discharge hopper 9, and the discarded bags are placed on the drum screen 3. The material falls into the waste bag collection cylinder 10 under the action of the guide plate; all the material falling into the feed hopper 9 will be collected into the material collection cylinder 7. Under the action of the material conveyor screw 8, the material is collected into the feed port at one end of the material collection cylinder 7; the waste bags fall into the waste bag collection cylinder 10 from the tail of the drum screen 3. The waste bag screw 11 in the waste bag collection cylinder 10 squeezes and discharges the waste bags; in this device, the bag cutting, material bag separation and waste bag collection are arranged in a production line manner inside the equipment, resulting in a compact overall structure, small size and higher unpacking efficiency.

[0036] This application has a high degree of automation, and can automatically complete the unpacking process and waste bag collection process, reducing manual intervention and improving production efficiency;

[0037] This application has a high emptying rate. The cutter auger 1 and the drum screen 3 work together on the bag to achieve a high material emptying rate, with very little material residue in the empty bag.

[0038] This application has strong applicability; the same equipment can be used for bag materials of various specifications and different material structures.

[0039] This application is easy to maintain: the equipment has a high degree of integration, a reasonable structural design, and is relatively easy to maintain, thus reducing the application cost.

[0040] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
