Description

Technical Field

[0001] This utility model relates to the technical field of package breaking machines and package unpacking machines, and in particular to a package breaking machine. Background Technology

[0002] A bag-breaking machine (also known as an automatic bag-opening machine or diaphragm opener) is a piece of equipment used for automatically unpacking bagged powder and granular materials. It is widely used in industries such as chemical, building materials, and food, enabling efficient and dust-free unpacking and unloading operations. By automating the process, the bag-breaking machine solves the problems of dust pollution, low efficiency, and safety risks associated with traditional manual unpacking, making it particularly suitable for handling sensitive or hazardous materials.

[0003] When the packaging bag comes into contact with the tearing blade, the packaging bag is easily shaken by the force, which affects the tearing efficiency. At the same time, the existing packaging bag tearing machine has a complex structure and many parts, resulting in high equipment cost. Utility Model Content

[0004] The purpose of this utility model is to provide a bag-breaking machine with a simple and reasonable structure and stable and reliable operation; it greatly reduces the shaking of packaging bags when breaking them, making the bag-breaking efficiency higher; its bag-discharging design is simple, efficient, and low-cost.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A bag breaking machine includes a frame, a bag lifting platform, a bag gripping assembly, a bag breaking assembly, a receiving bin, and a bag discharge port;

[0007] The frame is vertically arranged, with a bag-grabbing assembly at the top and a bag-breaking assembly, a receiving bin, and a bag-lifting platform below the bag-grabbing assembly.

[0008] The lifting platform is a lifting platform on which packaging bags to be opened are placed; the lifting platform (lifting platform) is existing technology and a conventional technical means, so it will not be described in detail here.

[0009] A horizontally positioned bag-grabbing component is provided above the bag-lifting platform;

[0010] The bag-grabbing assembly includes a mounting frame, a bag-grabbing frame, a bag-gripping cylinder, grippers, a main swing arm, a secondary swing arm, a connecting rod, an active rotating gear, a driven rotating gear, a drive motor, an active rotating shaft, a driven rotating shaft, and rollers.

[0011] The mounting bracket is horizontally arranged, with an active rotating shaft and a driven rotating shaft at its left and right ends, respectively; rollers are fitted at the front and rear ends of the active and driven rotating shafts, respectively; a drive motor is connected to the active rotating shaft and drives the active rotating shaft to rotate.

[0012] The top of the frame is provided with a horizontal beam guide rail; the roller is pressed on the horizontal beam guide rail and moves left and right along the horizontal beam guide rail; the drive motor drives the roller to rotate through the drive shaft, thereby moving the mounting frame left and right along the horizontal beam guide rail.

[0013] The bag-gripping frame is horizontally positioned, and several main swing arms and auxiliary swing arms are horizontally positioned and rotatably connected to the bag-gripping frame. Each main swing arm has several main grippers, and each auxiliary swing arm has several auxiliary grippers. The main and auxiliary grippers face each other, forming a pair of grippers capable of holding the packaging bag. Several main and auxiliary grippers form several pairs of grippers, with short distances between them; multiple pairs of short-distance grippers provide a more stable and reliable grip on the packaging bag.

[0014] The output shaft of the bag-clamping cylinder is hinged to one end of a connecting rod, and the other end of the connecting rod is fixedly connected to the main swing arm. That is, the bag-clamping cylinder can push and pull the main swing arm through the connecting rod to make the main swing arm swing.

[0015] The main swing arm has an active rotating tooth fitted on its end face, and the secondary swing arm has a driven rotating tooth fitted on its end face; the active and driven rotating teeth are meshed together. This allows the secondary swing arm to rotate when the main swing arm rotates, and the two rotate in opposite directions, thus enabling the main and secondary grippers to grip the packaging bag together, and similarly, to release the packaging bag.

[0016] The main gripper and the secondary gripper are mechanical grippers with a spider claw-like structure.

[0017] The bag-breaking assembly includes a bag-breaking motor, bag-breaking blades, a bag-breaking shaft, and guide rollers. The bag-breaking shaft is horizontally positioned, with one end connected to the output shaft of the bag-breaking motor. Several vertically positioned bag-breaking blades are fitted onto its middle section. A guide roller is located on the right side of each bag-breaking blade. When the bag-gripping assembly clamps the bag and moves towards the bag-breaking blades, the bottom of the bag first slides past the guide rollers, causing the bag to be squeezed and pushed upwards. After sliding past the guide rollers, it falls back and presses against the rotating bag-breaking blades. The downward pressure of gravity further helps the bag-breaking blades slide down the bottom of the bag. Simultaneously, the guide rollers also help the bag enter the bag-breaking assembly stably. With the main and secondary grippers holding the bag at the top and the guide rollers supporting it at the bottom, the bag enjoys vertical stability, significantly reducing the shaking of the front surface of the bag when it contacts the bag-breaking blades.

[0018] The receiving hopper is equipped with several grid strips above it, which allow powdery and granular materials to enter the receiving hopper. Damaged packaging bags are blocked by the grid strips and discharged through the bag discharge port on the frame.

[0019] The bag-grabbing assembly has a bag-discharging assembly on its left side, which includes a bag-discharging cylinder and a bag-discharging rake. The front and rear ends of the bag-discharging rake are rotatably connected to the bag-grabbing frame. The bag-discharging cylinder is fixed on the bag-grabbing frame, and its output shaft is hinged to the middle section of the bag-discharging rake. By operating the bag-discharging cylinder, the bag-discharging rake can be driven to rotate and swing, making a sweeping action, which can sweep the damaged packaging bags on the grid strips out of the bag-discharging opening.

[0020] The beneficial effects of this utility model are:

[0021] Its structure is simple and reasonable, and its operation is stable and reliable;

[0022] Its design, featuring multiple sets of short-pitch grippers and guide rollers, significantly reduces the shaking of packaging bags during tearing, resulting in higher tearing efficiency.

[0023] Its bag-dispensing design is simple, efficient, and low-cost. Attached Figure Description

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figures 1-10 As shown, a bag-breaking machine includes a frame 1, a bag-lifting platform 2, a bag-grabbing assembly 3, a bag-breaking assembly 8, and a receiving bin 5;

[0036] The frame 1 is vertically arranged, with a bag gripping component 3 on its top, and a bag breaking component 8, a receiving bin 5, and a bag lifting platform 2 below the bag gripping component 3.

[0037] The lifting platform 2 is a lifting platform on which the packaging bags 7 to be opened are placed. The lifting platform 2 (lifting platform) is existing technology and a conventional technology, so it will not be described in detail here. The lifting platform 2 includes a base, a lifting motor, gears, and a chain. The lifting motor drives the vertically arranged chain transmission, and the end face of the base is connected to the chain, thereby driving the base to rise and fall.

[0038] A horizontally arranged bag-grabbing component 3 is provided above the bag-lifting platform 2;

[0039] The bag-grabbing assembly 3 includes a slide 31, a bag-grabbing frame 32, a bag-gripping cylinder 33, a gripper, a main swing arm 35, a secondary swing arm 36, a connecting rod 37, an active rotating gear 38, a driven rotating gear 39, a drive motor 40, an active rotating shaft 41, a driven rotating shaft 42, and a roller 43.

[0040] The carriage 31 is horizontally arranged, with an active rotating shaft 41 and a driven rotating shaft 42 at its left and right ends respectively; rollers 43 are respectively fitted at the front and rear ends of the active rotating shaft 41 and the driven rotating shaft 42; the drive motor 40 is connected to the active rotating shaft 41 and drives the active rotating shaft 41 to rotate.

[0041] The frame 1 is provided with a horizontal beam guide rail 11 at the top. The horizontal beam guide rail 11 is set horizontally. The roller 43 is pressed on the horizontal beam guide rail 11 and moves left and right along the horizontal beam guide rail 11. The drive motor 40 drives the roller 43 to rotate through the drive shaft, thereby moving the slide 31 left and right along the horizontal beam guide rail 11.

[0042] The bottom end of the slide 31 is connected to the bag grabber 32 via the upright 44.

[0043] The bag gripper 32 is horizontally arranged, and several main swing arms 35 and auxiliary swing arms 36 are horizontally arranged and rotatably connected to the bag gripper 32. The main swing arms 35 are provided with several main grippers 351, and the auxiliary swing arms 36 are provided with several auxiliary grippers 361. The main grippers 351 and auxiliary grippers 361 are arranged facing each other to form a pair of grippers that can grip the packaging bag 7.

[0044] The output shaft of the bag-clamping cylinder 33 is hinged to one end of the connecting rod 37, and the other end of the connecting rod 37 is fixedly connected to the main swing arm 35. That is, the bag-clamping cylinder 33 can push and pull the main swing arm 35 through the connecting rod 37, so that the main swing arm 35 swings.

[0045] The end face of the main swing arm 35 is fitted with an active rotating tooth 38, and the end face of the auxiliary swing arm 36 is fitted with a driven rotating tooth 39; the active rotating tooth 38 and the driven rotating tooth 39 are engaged. This allows the main swing arm 35 to rotate, driving the auxiliary swing arm 36 to rotate in opposite directions, thus enabling the main gripper 351 and the auxiliary gripper 361 to grip the packaging bag 7, and similarly, to release the packaging bag 7. Several main grippers and auxiliary grippers form several pairs of grippers, and the short distance between the main grippers and auxiliary grippers allows for a more stable and reliable gripping of the packaging bag.

[0046] The main gripper 351 and the secondary gripper 361 are mechanical grippers with a spider claw-like structure.

[0047] The package breaking assembly 8 includes a package breaking motor 81, package breaking blades 82, a package breaking shaft 83, and a guide roller 84.

Several vertically positioned package breaking blades 82 are sleeved in its middle section. The guide roller 84 is located on the right side of the package breaking blades 82. When the package gripping assembly 3 clamps the package bag 7 and moves towards the package breaking blades 82, the bottom of the package bag 7 first slides over the guide roller 84. The package bag 7 is squeezed and pushed upwards. After sliding over the guide roller 84, it falls back and presses against the rotating package breaking blades 82. With the help of gravity, the package breaking blades 82 further help the bottom of the package bag 7 slide down. At the same time, the guide roller 84 also helps the package bag 7 to enter the package breaking assembly 8 stably. That is, the upper part of the package bag 7 is gripped by the main gripper 351 and the secondary gripper 361, and the bottom is supported by the guide roller 84. The package bag 7 has a stable vertical effect, which greatly reduces the shaking of the front face of the package bag 7 when it contacts the package breaking blades 82. The guide rollers 84 are horizontally arranged, and their front and rear ends are rotatably connected to the frame 1 respectively; preferably, there are several guide rollers 84, which are arranged in an inclined upward manner.

[0048] The receiving hopper 5 is provided with several grid strips 51 above it, allowing powdery and granular materials to enter the receiving hopper 5.
