Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unpacking machines, specifically relating to an end-opening bag 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 some existing unpacking machines, the bags at the loading station are gripped by the grippers of the conveying mechanism and transported from the loading station to the cutting mechanism to cut the bags. Then, the bags are shaken to separate them from the materials. Finally, the conveying mechanism transports the bags to the waste bag collection mechanism before entering the next work cycle. In other words, the conveying mechanism must go through the complete unpacking process before returning to the loading station to unpack the next bag. Therefore, the total unpacking time for a single bag is relatively long and the unpacking efficiency is low. Utility Model Content
[0004] In view of the problems in the prior art, this utility model provides an end-opening bag-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] An end-opening bag-unpacking machine includes a machine housing, which is equipped with a bag-grabbing platform, a feeding hopper, a waste bag collection mechanism, a traveling mechanism, a bag-grabbing mechanism, a bag-turning mechanism, and a bag-cutting mechanism. The feeding hopper is located between the bag-grabbing platform and the waste bag collection mechanism. The machine housing has a feeding port on one side of the bag-grabbing platform.
[0007] The traveling mechanism is located on the top of the machine box. The traveling mechanism is used to support the bag grabbing mechanism to reciprocate directly above the bag grabbing platform and directly above the unloading hopper.
[0008] The bag-grabbing mechanism is used to grip the bag;
[0009] The bag-turning mechanism includes a flipping grid plate and a first driving member. The flipping grid plate has several material passage holes and is located at the opening of the hopper. The end of the flipping grid plate near the waste bag collection mechanism is rotatably connected to the machine box. The first driving member is used to drive the flipping grid plate to flip in the vertical direction.
[0010] The bag-cutting mechanism is used to cut open bags from the bag-grabbing platform.
[0011] The walking mechanism includes a track set on the top of the chassis and a trolley slidably set on the track, and the bag-grabbing mechanism is set on the trolley.
[0012] The trolley is equipped with a lifting bracket and a second driving component. The second driving component is used to drive the lifting bracket to perform lifting and lowering movements. The bag-grabbing mechanism is located on the lifting bracket.
[0013] The bag-grabbing mechanism includes a bag-grabbing frame and several bag-grabbing hooks disposed at the bottom of the bag-grabbing frame, which is mounted on a lifting support.
[0014] A bag-shaking cylinder is rotatably mounted on the lifting support. One end of the bag-grabbing frame is rotatably connected to the lifting support, and the drive end of the bag-shaking cylinder is rotatably connected to the lifting support.
[0015] The flip-up grating has an upward-opening bend in the middle.
[0016] The bag cutting mechanism includes a cutter and a third driving component. The cutter is circular and is vertically positioned above the hopper. The third driving component is used to drive the cutter to rotate.
[0017] The waste bag collection mechanism includes a waste bag collection cylinder and a spiral auger disposed inside the waste bag collection cylinder, with the opening of the waste bag collection cylinder facing upward.
[0018] A dust removal port is provided on one side of the chassis.
[0019] A feeding conveyor belt is installed on the outside of the chassis, and the feeding direction of the feeding conveyor belt is towards the feed inlet.
[0020] The above-described structure of this utility model can achieve the following beneficial effects:
[0021] After the bag is positioned at the chute, the lifting mechanism descends, the bag-grabbing mechanism grabs the bag, and the lifting mechanism rises to its position. Then, the traveling mechanism starts and moves the grabbed bag directly above the lower hopper. During the movement, the bag passes through the bag-cutting mechanism, which cuts the bag open. After it reaches its position, the bag-shaking cylinder starts to shake the bag, and the material falls through the flip-over grid plate into the discharge hopper. After the shaking action is completed, the bag-grabbing mechanism starts to release the bag, and the bag falls onto the flip-over grid plate. The first drive unit drives the flip-over grid plate to rotate to a vertical position towards the waste bag collection mechanism. Due to its own gravity, the bag slides into the waste bag collection cylinder, where the spiral auger squeezes and discharges the waste bag from the equipment. Then, the flip-over grid plate can be reset. After the bag-grabbing mechanism releases the bag, it can immediately return to directly above the chute for the next grab. Since the grabbing mechanism can perform the next grab while the waste bag is flipping into the waste bag collection mechanism, the two unpacking steps are performed simultaneously, improving unpacking efficiency.

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.
[0028] 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.
[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0030] refer to Figure 1-3 The end-opening bag-unpacking machine shown includes a machine housing, which is equipped with a bag-grabbing platform 1, a feeding hopper 2, a waste bag collection mechanism, a walking mechanism, a bag-grabbing mechanism, a bag-turning mechanism, and a bag-cutting mechanism. The feeding hopper 2 is located between the bag-grabbing platform 1 and the waste bag collection mechanism. The machine housing has a feeding port on one side of the bag-grabbing platform 1.
[0031] The traveling mechanism is located on the top of the machine box. The traveling mechanism is used to support the bag grabbing mechanism to reciprocate directly above the bag grabbing platform 1 and directly above the unloading hopper 2.
[0032] The bag-grabbing mechanism is used to grip and hold bags;
[0033] The bag-turning mechanism includes a flipping grid plate 3 and a first driving member. The flipping grid plate 3 has several material passage holes. The flipping grid plate 3 is located at the opening of the hopper 2. The end of the flipping grid plate 3 near the waste bag collection mechanism is rotatably connected to the machine box. The first driving member is used to drive the flipping grid plate 3 to flip in the vertical direction.
[0034] The bag-cutting mechanism is used to cut open bags from the bag-grabbing platform 1.
[0035] Based on the above structure, after the bag is positioned at the grabbing platform 1, the grabbing mechanism clamps the bag. Then, after the traveling mechanism is activated, the grabbing mechanism moves directly above the lower hopper 2. During the movement, the bag passes through the bag-cutting mechanism, which cuts the bag open. The material then falls onto the flipping grid plate 3, passes through the material passage holes of the flipping grid plate 3, and falls into the lower hopper 2. Then, the grabbing mechanism releases the bag, and the bag falls onto the flipping grid plate 3. The first driving component drives the flipping grid plate 3 to rotate towards the waste bag collection mechanism, causing the bag to flip into the waste bag collection mechanism. Then, the flipping grid plate 3 resets. After the grabbing mechanism releases the bag, it can immediately return to directly above the grabbing platform 1 for the next grabbing. Since the grabbing mechanism can perform the next grabbing while the bag is flipping into the waste bag collection mechanism, the two unpacking steps are performed simultaneously, improving the unpacking efficiency.
[0036] like Figures 1-4As shown, the traveling mechanism includes a track 4 mounted on the top of the chassis and a traveling trolley 5 slidably mounted on the track 4. The traveling trolley 5 is equipped with a lifting bracket 6 and a second driving component. The second driving component drives the lifting bracket 6 to move up and down. The bag-grabbing mechanism includes a bag-grabbing frame 7 and several bag-grabbing hooks (these hooks are arranged in multiple groups and are positioned opposite each other to grip the bag from both sides and the middle, preventing the bag material from loosening and collapsing) mounted on the lifting bracket 6. The bag-grabbing frame 7 is mounted on the lifting bracket 6. A rotating mechanism is mounted on the lifting bracket 6... A bag-shaking cylinder 8 is provided, and one end of the bag-grabbing frame 7 is rotatably connected to the lifting bracket 6. The driving end of the bag-shaking cylinder 8 is rotatably connected to the lifting bracket 6. Thus, the second driving component drives the lifting bracket 6 to move up and down, that is, drives the bag-grabbing frame 7 to move up and down, to grasp the bags on the bag-grabbing platform 1. When the bag moves to directly above the discharge hopper 2, the work done by the bag-shaking cylinder 8 causes one end of the bag-grabbing frame 7 to swing (causing the angle between the bag-grabbing frame 7 and the horizontal plane to change), which shakes the bag and makes the material inside the bag fall as much as possible.
[0037] like Figure 1 As shown, in order to prevent materials from sliding from the side of the flip grid plate 3 into the waste bag collection mechanism, the flip grid plate 3 is provided with an upward-opening bend (i.e., the center of the flip grid plate 3 is concave), so that after the materials fall on the flip grid plate 3, they will move towards the center of the flip grid plate 3.
[0038] like Figure 1 As shown, the bag cutting mechanism includes a cutter 9 and a third drive unit. The cutter 9 is circular and is vertically positioned above the hopper 2 (the cutter 9 is located on the side close to the bag conveyor plate 1). The third drive unit is used to drive the cutter 9 to rotate. Thus, when unpacking, the third drive unit drives the cutter 9 to rotate. Since the cutter 9 is vertically positioned, when the bag moves directly above the hopper 2, one end of the bag is released from the cutter 9, causing the end of the bag to be cut open.
[0039] like Figure 1 and 2 As shown, the waste bag collection mechanism includes a waste bag collection cylinder 10 and a spiral auger 11 disposed inside the waste bag collection cylinder 10. The opening of the waste bag collection cylinder 10 faces upward (i.e., an opening is provided in the circumferential direction of the waste bag collection cylinder 10). After the waste bag is flipped by the flipping grid plate 3, it falls into the waste bag collection cylinder 10. After being squeezed by the rotation of the spiral auger 11, it is conveyed out of the machine box.
[0040] Further optimizations include, for example Figure 1 As shown, a dust removal interface 12 is provided on one side of the chassis. Except for the feed port and other necessary openings, the rest of the chassis is sealed. Before the equipment is run, the dust removal interface 12 is connected to the dust removal equipment on site. The dust removal equipment works to create a negative pressure space inside the equipment to prevent dust from overflowing during unpacking operations.
[0041] like Figure 2 As shown, a feeding conveyor belt 13 is installed on the outside of the machine box. The feeding direction of the feeding conveyor belt 13 is towards the feed inlet. Simply place the bag on the feeding conveyor belt 13, and the bag can be conveyed to the bag grabbing platform 1. The angle and height of the feeding conveyor belt 13 can be set according to the site conditions to improve the convenience of feeding.
[0042] In summary, after the bag is positioned at the bag conveyor plate 1, the lifting mechanism descends, the bag grabbing mechanism grabs the bag, and the lifting mechanism rises to its position. Then, the traveling mechanism starts and moves the grabbed bag directly above the lower hopper 2. During the movement, the bag passes through the bag cutting mechanism, which cuts the bag open. After the bag is in position, the bag shaking cylinder starts to shake the bag, and the material falls through the tilting grid plate 3 into the lower hopper 2. After the bag shaking action is completed, the bag grabbing mechanism starts to release the bag, and the bag falls onto the tilting grid plate 3. The first driving component drives the tilting grid plate. Plate 3 rotates to a vertical position towards the waste bag collection mechanism. The bag slides into the waste bag collection cylinder 10 due to its own gravity. The spiral auger 11 inside the waste bag cylinder squeezes the waste bag and discharges it from the equipment. Then, the grid plate 3 is flipped over to reset. After the bag grabbing mechanism releases the bag, it can immediately return to the top of the bag chute 1 for the next grabbing. Since the grabbing mechanism can perform the next grabbing while the waste bag is being flipped into the waste bag collection mechanism, the two unpacking steps are carried out simultaneously, which improves the unpacking efficiency.
[0043] 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;
[0044] This application has strong applicability; the same equipment can be used for bag materials of various specifications and different material structures.
[0045] 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;
[0046] This application features a compact structure and small size, which can effectively solve the problem of limited space for some customers and goods with insufficient production space. It saves material costs and social resources, which is in line with the concept of sustainable development.
[0047] 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.
