Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, in particular to a structure for automatically removing outer bags from bagged small packages. Background Art

[0002] With the development of automation technology, the demand for automatic bag removal equipment for bagged small packages is growing rapidly in the food, chemical and many other industries with extremely high requirements for product quality and hygiene standards. These devices can complete the work of removing outer bags efficiently and accurately, greatly improving production efficiency and reducing the tediousness and errors of manual operations, thereby ensuring product quality and the hygiene and safety of the production process.

[0003] However, many current methods for unpacking small bags rely on simultaneously cutting the inner and outer bags. Although this process can be automated, bag debris and dirt attached to the outer bag may mix into the material during the cutting process, causing secondary contamination. Especially when using double-layer bags with PE inner bags, the existing cutting packaging technology will result in a significant residue rate, which is much higher than that of cutting single-layer bags. This high residue rate not only increases material loss, but also makes cleaning more difficult during subsequent processing, thereby affecting production efficiency and product quality. Although manual bag removal is a relatively simple solution, it is labor-intensive, inefficient, and has high labor costs. It is not suitable for large-scale production needs. At the same time, the maintenance cost and price of the bag cutting machine are also very high.

[0004] Based on this, the utility model designs a bagged small package automatic outer bag removal structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a structure for automatically removing the outer bag of a bagged small package, so as to solve the problems raised in the above background technology.

[0007] Preferably, the pneumatic suction cup mechanism includes a pneumatic component and a sponge suction cup, and the pneumatic component is provided in two groups, the two groups of pneumatic components are symmetrically arranged, and the output end of the pneumatic component is transmission-connected to the sponge suction cup.

[0008] Preferably, the pushing and grabbing mechanism includes a fixed rod, a connecting rod and a rodless cylinder. Two fixed rods are provided, and the two fixed rods are symmetrically fixedly connected to the side plates on the front and rear sides of the belt conveyor. The right side of the top end of the fixed rod is fixedly connected to a connecting rod, and the top of the right end of the connecting rod is fixedly installed with a rodless cylinder.

[0009] Preferably, the connecting rod is located directly above the sponge suction cup on the right side, and the rodless cylinder corresponds to the sponge suction cup on the right side.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] The utility model realizes the automatic outer bag removal function of bagged packages by arranging a belt conveyor, a pneumatic suction cup mechanism, a pushing and grabbing mechanism and a lifting mechanism to cooperate with each other, effectively avoiding the secondary pollution problem that may be caused by cutting the inner and outer bags, thereby improving production efficiency and product quality, and is easy to maintain, reducing production costs, and meeting the needs of large-scale production. The pneumatic suction cup mechanism can accurately adsorb bagged packages, and the soft characteristics of the sponge suction cup ensure that the packaging bag will not be damaged during the adsorption process, thereby maintaining the integrity of the packaging. The use of the pushing and grabbing mechanism ensures the stable grasping and pushing of the bagged packages during the transportation process, preventing production interruption and material loss caused by sliding or falling. The lifting mechanism makes the belt conveyor rise on one side to form an inclined angle, prompting the inner bag to automatically slide out by gravity, realizing the transformation from double-layer bags to single-layer bags, greatly reducing the residual rate, saving labor, and reducing costs and energy consumption.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] See also Figure 1 - Figure 2 Example 1 is described. The figure shows an automatic outer bag removal structure for bagged packages, including a belt conveyor 1. A mounting groove 101 is opened at the center of the belt conveyor 1. A pneumatic suction cup mechanism 2 is fixedly installed in the mounting groove 101. A pushing and grabbing mechanism 3 is provided on the left side of the pneumatic suction cup mechanism 2. The pushing and grabbing mechanism 3 is fixedly connected to the belt conveyor 1. The bottom of the belt conveyor 1 is connected to a lifting mechanism 4. A reflecting photoelectric device 5 is provided on the right side of the pneumatic suction cup mechanism 2. The reflecting photoelectric device 5 is fixedly installed on the belt conveyor 1. The right end of the bottom of the belt conveyor 1 is connected to a hinge 6. The bottom of the hinge 6 is connected to a support frame 7. The top of the support frame 7 is provided with the belt conveyor 1, and the right end of the rear side of the belt conveyor 1 is connected to a power component 8.

[0020] See also Figure 2 The pneumatic suction cup mechanism 2 shown in the figure includes a pneumatic component 201 and a sponge suction cup 202. The pneumatic component 201 is provided with two groups, and the two groups of pneumatic components 201 are symmetrically arranged. The output end of the pneumatic component 201 is transmission-connected to the sponge suction cup 202;

[0021] In this embodiment, the food material bag (the outer bag opening at the front end is open) transported by the belt conveyor 1 is precisely stopped by controlling the photoelectric signal 5. After the pneumatic component 201 at the bottom is energized, it drives the sponge suction cup 202 to rise and suck the outer bag. Once the outer bag is sucked, the lifting mechanism 4 and the hinge 6 work together to make the belt conveyor 1 rise and form a certain angle. In this way, the inner bag will automatically slide out of the outer bag under the action of gravity. After sliding out, the belt conveyor 1 returns to its initial position and controls the pushing and grabbing mechanism 3 to push the outer bag out of the line body. A rectangular trash can is provided outside the line body for recycling the outer bag. The entire line body operates in a cycle. The entire outer bag removal process is highly automated and easy to operate, which greatly improves production efficiency and product quality.

[0022] Specifically, by opening an installation groove 101 in the middle of the belt conveyor 1 and placing a pneumatic suction cup mechanism 2, the vacuum sponge suction cup 202 is used to grab the outer bag, which effectively solves the problem of separation of pollutants and materials generated by the outer bag during transportation and production. In addition, by raising the belt conveyor 1 on one side to form an angle, the inner bag can automatically slide out by gravity, realizing the transformation from a double-layer bag to a single-layer bag, significantly reducing the residual rate. At the same time, the rodless cylinder 303 pushed out from the upper part solves the function of automatically removing the line body of the empty outer bag, thereby reducing costs and energy consumption.

[0023] It should be noted that the power component 8 adopts a common reduction motor group, which uses the power component 8 to provide power for the belt conveyor 1 to ensure the smooth progress of the entire outer bag removal process. The output shaft of the power component 8 is connected to the drive shaft of the belt conveyor 1. Through the adjustment of the reduction motor group, the operating speed of the belt conveyor 1 can be accurately controlled to adapt to different production needs.

[0024] Example 2

[0025] See also Figure 2 Example 2 is described. This embodiment further describes Example 1. In the figure, the pushing and grabbing mechanism 3 includes a fixed rod 301, a connecting rod 302 and a rodless cylinder 303. Two fixed rods 301 are provided. The two fixed rods 301 are symmetrically fixedly connected to the side panels on the front and rear sides of the belt conveyor 1. The right side of the top of the fixed rod 301 is fixedly connected to the connecting rod 302, and the top of the right end of the connecting rod 302 is fixedly installed with a rodless cylinder 303.

[0026] Furthermore, the connecting rod 302 is located directly above the sponge suction cup 202 on the right side, and the rodless cylinder 303 corresponds to the sponge suction cup 202 on the right side;

[0027] In this embodiment, when the belt conveyor 1 rises on one side to form an angle, the inner bag can automatically slide out by gravity, realizing the transformation from a double-layer bag to a single-layer bag, and the pushing and grabbing mechanism 3 is immediately actuated, and the rodless cylinder 303 directly above the sponge suction cup 202 pushes the outer bag out of the wire body, solving the function of automatically removing the empty outer bag from the wire body, thereby reducing costs and energy consumption, and completing the entire outer bag removal process.

[0028] It should be noted that the use of the rodless cylinder 303 greatly improves the efficiency and accuracy of removing the outer bag. Since the telescopic action of the rodless cylinder 303 can be precisely controlled, and at the same time, the rodless cylinder 303 has a simple structure, easy maintenance, and a long service life, it further reduces the maintenance cost and failure rate of the equipment.

[0029] Example 3

[0030] See also Figure 1 Example 3 is described. This embodiment further illustrates Example 2. In the figure, the lifting mechanism 4 includes a telescopic cylinder 401, a bearing seat 402 and a rotating shaft 403. The telescopic cylinder 401 is fixedly mounted on the support frame 7, and the bearing seat 402 is fixedly connected to the bottom of the belt conveyor 1. The rotating shaft 403 is rotatably connected in the bearing seat 402, and the rotating shaft 403 is fixedly connected to the output end of the telescopic cylinder 401.

[0031] Furthermore, the right end of the bottom of the belt conveyor 1 is movably connected to the support frame 7 through a hinge 6, and the left end of the bottom of the belt conveyor 1 is placed on the support frame 7;

[0032] In this embodiment, the telescopic cylinder 401 is powered on and outputs power, pushing the rotating shaft 403 to rotate, thereby driving the belt conveyor 1 to rise as a whole, and forming a predetermined angle with the cooperation of the hinge 6. The setting of this angle enables the inner bag in the material bag to slide out of the outer bag smoothly under the action of gravity. When the inner bag slides out completely, the telescopic cylinder 401 is powered off, and the belt conveyor 1 returns to its initial position under the action of gravity, ready for the next outer bag removal operation. In this way, a continuous and automated outer bag removal process can be achieved, greatly improving production efficiency.

[0033] Specifically, the telescopic action of the telescopic cylinder 401 can be precisely controlled to ensure the stability of the belt conveyor 1 during the rising and falling process, avoiding the problem of damage to the material bags or incomplete outer bag removal due to improper operation. At the same time, since the lifting mechanism 4 has a simple structure, convenient maintenance and long service life, the maintenance cost and failure rate of the equipment are further reduced, and an efficient and automated outer bag removal process of the material bags is realized. This structure not only improves production efficiency, but also ensures product quality, while reducing production costs and energy consumption.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
