Sliding bag type bale breaker

Abstract

The utility model belongs to the field of bale breakers, and particularly relates to a sliding bag type bale breaker. When the bag sliding device is used, a bag slides on the bag sliding grating plate, meanwhile, the cutting knife cuts the lower portion of the bag open, and part of materials can preferentially flow into the discharging hopper; when the bag slides to the bag blocking plate, after the bag shaking mechanism moves downwards in place, the bag grabbing mechanism grabs the bag to make rising movement, after rising movement is in place, the bag shaking action is conducted, and materials are shaken off and fall into a discharging hopper; after bag shaking is finished, the bag blocking plate rotates towards one side of the waste bag collecting mechanism in place, the claw hooks of the bag grabbing mechanism are loosened, empty bags after material separation fall down and directly slide to the waste bag collecting mechanism along the bag sliding grating plate and the bag blocking plate, and therefore unpacking work is completed. Due to the fact that a parallel moving mechanism is reduced and the relative installation positions of all parts of the device are optimized, the size of the device is reduced, the requirements of customers for use space can be met, and the situation that dust affects work of the horizontal moving mechanism is avoided.

Description

Technical Field

[0001] This utility model belongs to the field of unpacking machines, specifically relating to a bag-sliding 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, bags containing materials enter the equipment via a conveyor belt, slide down a chute to the unpacking position, and are then gripped by a lifting and grabbing mechanism. After gripping, the bags are moved to the unpacking area by a trolley mechanism. During this movement, a cutter cuts the bags open, and the material flows into a hopper. The grabbing mechanism then releases the bags, which fall onto a flipping plate. The flipping plate flips, causing the bags to fall into a waste bag collection mechanism, while the trolley moves back to the grabbing position. However, the trolley mechanism requires guide rails and other supporting structures, resulting in a large equipment size that may not meet the space requirements of some customers. Furthermore, when unpacking powder bags, dust accumulates on the top of the equipment, which is difficult to clean and can affect the operation of the linear guide rails and trolley mechanism on the top of the equipment.

[0004] In view of this, there is an urgent need for a bag-opening machine to solve the above problems. Utility Model Content

[0005] In view of the problems in the prior art, this utility model provides a bag-sliding unpacking machine to solve the problems in the prior art.

[0006] To achieve the above technical objectives, the technical solution of this utility model is as follows:

[0007] A bag-sliding unpacking machine includes a machine housing, inside which are arranged a bag-sliding grid plate, a bag-blocking plate, a cutting mechanism, a bag-shaking mechanism, a waste bag collection mechanism, and a first driving component. A bag inlet is provided on one side of the machine housing, and the bag-sliding grid plate extends downward at an angle from the bag inlet side.

[0008] The cutting mechanism is used to cut the bags that enter the bag grating plate;

[0009] The waste bag collection mechanism is located on the side of the bag chute away from the bag inlet, and the waste bag collection mechanism is used to collect waste bags;

[0010] The bag baffle is rotatably mounted on the bag trough plate. The first driving member is used to drive the bag baffle to rotate, so that the positional relationship between the bag baffle and the bag trough plate can be switched back and forth between parallel and perpendicular.

[0011] The bag-shaking mechanism is used to grab bags on the bag grating plate and shake them to increase the material emptying rate.

[0012] The cutting mechanism includes a cutting blade and a second driving member. The cutting blade is circular and is vertically mounted on the bag sluice grid plate. The cutting blade extends circumferentially above the bag sluice grid plate. The second driving member is used to drive the cutting blade to rotate.

[0013] The cutter is positioned on the side of the bag grating plate near the bag inlet.

[0014] The bag-shaking mechanism includes a lifting bracket, a third driving component, and a bag-grabbing assembly. The lifting bracket is suspended directly above the bag-sliding grid plate. The third driving component is used to drive the lifting bracket to move up and down. The bag-grabbing assembly is mounted on the lifting bracket and is used to grab bags.

[0015] The package grabbing assembly includes a package grabbing bracket and several claw hooks disposed at the bottom of the package grabbing bracket, which is mounted on a lifting bracket.

[0016] The bag-shaking mechanism also includes a bag-shaking cylinder. One side of the bag-grabbing bracket is rotatably mounted on the lifting bracket, and the bag-shaking cylinder is rotatably mounted on the lifting bracket. The output end of the bag-shaking cylinder is rotatably connected to the bag-grabbing bracket.

[0017] The waste bag collection mechanism includes a waste bag collection cylinder and a conveying 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 machine casing, and the feeding direction of the feeding conveyor belt is towards the bag inlet.

[0020] A hopper is provided below the bag grating plate.

[0021] The above-described structure of this utility model can achieve the following beneficial effects:

[0022] Material bags are fed into the bag chute plate inside the equipment through the bag inlet. The bags slide on the chute plate under their own weight until they stop at the baffle plate. The bags on the chute plate are then cut by a cutting mechanism. As the bags slide on the chute plate, some of the material inside flows into the hopper. When the bag reaches the baffle plate, a gripping mechanism descends, grabs the broken bag from the chute plate, and moves it upwards. Once in position, it shakes the bag to dislodge any remaining material into the hopper. After shaking, the baffle plate rotates towards the waste bag collection mechanism, aligning with the chute plate. The gripping mechanism then releases its claws, allowing the empty bag to fall and slide directly down the chute plate and baffle plate to the waste bag collection mechanism, thus completing the unpacking process. Optimizing the relative installation positions of the equipment components reduces the equipment size, meeting the space requirements of some customers and eliminating the problem of dust affecting the operation of the translation mechanism.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] 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.

[0033] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0034] refer to Figure 1-6 The bag unpacking machine shown includes a machine housing, inside which are arranged a bag grating plate 1, a bag baffle plate 2, a hopper 3, a cutting mechanism, a bag shaking mechanism, a waste bag collection mechanism, and a first driving component. A bag inlet is provided on one side of the machine housing. The bag grating plate 1 (which has strip holes to allow materials to pass through) extends downward at an angle from the bag inlet side. The hopper 3 is located below the bag grating plate 1.

[0035] The cutting mechanism is used to cut the bags that enter the bag grating plate 1;

[0036] The waste bag collection mechanism is located on the side of the bag chute plate 1 away from the bag inlet, and is used to collect waste bags;

[0037] The baffle plate 2 is located on the side of the bag conveyor grid plate 1 near the waste bag collection mechanism. The bottom of the baffle plate 2 is rotatably mounted on the bag conveyor grid plate 1. The first driving member is used to drive the baffle plate 2 to rotate, so that the baffle plate 2 and the bag conveyor grid plate 1 form a parallel or perpendicular relationship (when the baffle plate 2 and the bag conveyor grid plate 1 are in a parallel relationship, the top surfaces of the baffle plate 2 and the bag conveyor grid plate 1 tend to be on the same plane, so that the waste bag can slide off the bag conveyor grid plate 1; when the baffle plate 2 and the bag conveyor grid plate 1 are in a perpendicular relationship, the bag is prevented from sliding into the waste bag collection mechanism).

[0038] The bag-shaking mechanism is used to grab bags on the bag-sliding grid plate 1 and shake them.

[0039] Based on the above structure, the material bag is fed into the bag conveyor grid 1 inside the equipment from the bag inlet (at this time, the baffle plate 2 and the bag conveyor grid 1 are in a vertical position relationship). The material bag slides on the bag conveyor grid 1 under its own weight and stops at the baffle plate 2 (e.g., ...). Figure 3 (As shown); the bags entering the bag conveyor grating 1 are cut by the cutting mechanism. While the bags slide on the bag conveyor grating 1, some material will flow into the discharge hopper 3 first; when the bags slide to the baffle plate 2, the bag shaking mechanism is used to grab the bags on the bag conveyor grating 1 (as shown). Figure 4 As shown), and shake (as shown). Figure 5 As shown), the material falls onto the bag conveyor grid 1 and finally into the hopper 3; after the bag shaking is completed, the bag baffle 2 rotates towards the waste bag collection mechanism to form a parallel position with the bag conveyor grid 1, and then the gripping mechanism's claws release, and the empty bags after material separation fall (as shown). Figure 7 As shown in the figure, the bag slides directly onto the waste bag collection mechanism along the bag grating plate 1 and the bag baffle plate 2, thus completing the unpacking work; the relative installation positions of each component of the equipment have been optimized, thereby reducing the size of the equipment, which can meet the space requirements of some customers, and there is no dust affecting the operation of the translation mechanism.

[0040] like Figure 2 As shown, the cutting mechanism includes a cutting blade 4 and a second driving member. The cutting blade 4 is circular and is vertically mounted on the bag-feeding grid plate 1. The cutting blade 4 extends circumferentially to the top of the bag-feeding grid plate 1. The second driving member is used to drive the cutting blade 4 to rotate. The cutting blade 4 is located on the side of the bag-feeding grid plate 1 near the bag inlet. Thus, when the bag is placed on the bag-feeding grid plate 1, it is cut open as it slides down.

[0041] like Figure 2 and Figure 7 The bag-shaking mechanism shown includes a lifting bracket 5, a third drive component, and a bag-grabbing assembly. The lifting bracket 5 is suspended directly above the bag-sliding grid plate 1. The third drive component drives the lifting bracket 5 to move up and down. The bag-grabbing assembly includes a bag-grabbing bracket 6 and several claw teeth 7 (the claw teeth 7 are divided into multiple groups and arranged opposite each other, gripping the bag from both sides or inserting into the bag to fix it) located at the bottom of the bag-grabbing bracket 6. The bag-grabbing bracket 6 is mounted on the lifting bracket 5. The bag-shaking mechanism also includes a bag-shaking cylinder 8, with one side of the bag-grabbing bracket 6 rotatably mounted on the lifting bracket 5. On the lifting support 5, the shaking cylinder 8 is rotatably mounted on the lifting support 5, and the output end of the shaking cylinder 8 is rotatably connected to the bag grabbing support 6. Thus, the third driving component drives the lifting support 5 to move up and down, that is, drives the bag grabbing support 6 to move up and down, grabbing the bags on the bag grating plate 1, and then raising them so that the bags are suspended in the air. The work done by the shaking cylinder 8 causes one end of the bag grabbing support 6 to move up and down (causing the angle between the bag grabbing support 6 and the horizontal plane to change), which shakes the bags and makes the material inside the bags fall as much as possible.

[0042] like Figure 2 As shown, the waste bag collection mechanism includes a waste bag collection cylinder 9 and a conveying auger 10 disposed inside the waste bag collection cylinder 9. The opening of the waste bag collection cylinder 9 faces upward. The waste bags fall into the waste bag collection cylinder 9 through the baffle plate 2, and are conveyed out of the machine box by the rotation and compression of the conveying auger 10.

[0043] Further optimizations include, for example Figure 1 As shown, a dust removal interface 11 is provided on one side of the chassis. Except for the feed inlet and other necessary openings, the rest of the chassis is sealed. Before the equipment is put into operation, the dust removal interface 11 is connected to the dust removal equipment on site. The dust removal equipment works to suck away the dust in the chassis, so as to avoid affecting the operation of the equipment and preventing the dust from spreading to the outside.

[0044] like Figure 1 and Figure 2 As shown, a feeding conveyor belt 12 is installed on the outside of the machine box, and the feeding direction of the feeding conveyor belt 12 is towards the bag inlet. Simply place the bag on the feeding conveyor belt 12, and the bag can be transported to the bag sliding grid plate 1. The feeding conveyor belt 12 extends downward at an incline from the bag inlet. The inclination angle and height of the feeding conveyor belt 12 can be set according to the site conditions to improve the convenience of feeding.

[0045] In summary, the material bags are fed into the bag conveyor grid plate 1 inside the equipment through the bag inlet. The bags slide on the bag conveyor grid plate 1 under their own weight until they stop at the bag stop plate 2. The bags on the bag conveyor grid plate 1 are then cut by the cutting mechanism. While the bags slide on the bag conveyor grid plate 1, some material flows preferentially into the discharge hopper 3. When the bags reach the bag stop plate 2, the bag shaking mechanism grabs the bags on the bag conveyor grid plate 1 and shakes them, causing the material to fall back onto the bag conveyor grid plate 1 and finally into the discharge hopper 3. After the bag shaking is completed... The gripping mechanism releases its claws, and simultaneously the baffle plate 2 rotates towards the waste bag collection mechanism to be parallel to the bag conveyor grid 1. The empty bags after material separation fall and slide directly along the bag conveyor grid 1 and the baffle plate 2 to the waste bag collection mechanism, thus completing the unpacking work. The unpacking work is completed by reducing the translation movement steps. The relative installation positions of the various parts of the equipment are optimized, thereby reducing the size of the equipment, which can meet the space requirements of some customers, and there is no dust affecting the operation of the translation mechanism.

[0046] 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;

[0047] This application has strong applicability; the same equipment can be used for bag materials of various specifications and different material structures.

[0048] 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;

[0049] The overall size of the equipment in this application is more compact, the trolley traveling mechanism is eliminated, the lifting mechanism is fixed in position, the unpacking cycle time is shortened, the unpacking volume per unit time is increased, the space occupied in the production site is reduced, and after eliminating the traveling mechanism, the overall structure of the equipment has better sealing performance. At the same time, in industries such as pharmaceuticals, it is necessary to avoid raw material mixing. The equipment can be equipped with a water washing system according to customer needs, which can adapt to a wider range of customers and increase market competitiveness.

[0050] 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.
