Description

Technical Field

[0001] This utility model relates to the field of unpacking technology, specifically an unpacking machine that can be used for both large and small bag packaging. Background Technology

[0002] Powder materials are frequently used in various light and heavy industries such as environmental protection, chemical industry, pharmaceutical industry, food industry, metallurgy, building materials, and agricultural and sideline products. The materials are usually packaged in large ton bags or small bags of 25 kg or 50 kg, and usually need to be unpacked before use.

[0003] A search revealed that existing technologies, such as Chinese patent (authorization number: 211969980U), disclose a packaging unpacking machine that can be used for both large and small bags. The machine includes an upper support and a lower support. The upper support is fixedly connected to the upper end of the lower support, and the lower end of the upper support is fixedly connected to a crane via a crane beam. The lower end of the unpacking machine body has a discharge port. A ladder is placed below the front end of the lower support. The machine is equipped with a crane, upper support, lower support, bag opening port, screen, vibrator, dust collector, and control box. This allows the crane and manual labor to place large or small bags onto the unpacking machine body. The dust collector and vibrator absorb dust and vibrate the large bags, avoiding the limitations of existing technologies that cannot handle both large and small bags, have poor unpacking results, and leave residue. It also avoids the problems of excessive dust and noise.

[0004] However, the aforementioned patent requires workers to insert their hands into the opening of the bag when unpacking large packaging bags, without any protective structure. If the large packaging bags contain corrosive materials, such as powdered sodium hydroxide, using the aforementioned patent will cause sodium hydroxide powder to easily fall onto the hands during unpacking. Even if it does not cause hand injury in the short term, prolonged unpacking and unloading will inevitably cause injury to the workers' hands, and the material will also easily splash out from the opening, causing losses. Therefore, improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a packaging unpacking machine that can be used for both large and small bag packaging, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A packaging unpacking machine that can be used for both large and small bags includes a mounting plate. Multiple support rods arranged in a rectangular array are fixed to the bottom of the mounting plate. An electric slide rail is provided at the bottom of the mounting plate. An electric slider is provided at the bottom of the electric slide rail. An electric hoist is provided at the bottom of the electric slider. A pneumatic gripper is provided at the bottom of the electric hoist. An inverted frustum-shaped hopper is provided below the mounting plate. Connecting rods are fixed between the outer side of the hopper and each support rod.

[0008] The most significant design difference between this utility model and the prior art is that: a bag-unlocking tube is fixedly connected to the lower end of the hopper, and multiple equally spaced isolated bag-unlocking structures are provided on the bag-unlocking tube. There are six isolated bag-unlocking structures, each including an insertion hole opened on the bag-unlocking tube, into which a detachable protective glove is installed.

[0009] To enable the protective glove to be detachable, the insertion hole is a threaded hole, and an external threaded ring is threadedly installed inside the insertion hole. The arm end of the protective glove is fixed to the inner ring surface of the external threaded ring, and the fingertips extend into the unpacking tube.

[0010] To prevent the externally threaded ring from screwing into the unscrewing tube, the end extending into the hole extends inward to form a protrusion.

[0011] To facilitate the placement of scissors and the cut sealing line, a horizontal placement net is fixed on the inner wall of the unpacking tube, and a placement groove is provided at the top of the placement net.

[0012] Compared with the prior art, this utility model has the following advantages: the isolation bag-opening structure allows workers to avoid contact between their hands and materials when opening large packaging bags, preventing corrosive materials, such as powdered sodium hydroxide, from falling and causing injury. In addition, the protective gloves can seal the insertion hole to prevent materials from splashing out from the insertion hole. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1 As shown, this utility model provides a packaging unpacking machine that can be used for both large and small bags. It includes a mounting plate 1, with multiple support rods 2 arranged in a rectangular array fixed to the bottom of the mounting plate 1. An electric slide rail 3 is provided at the bottom of the mounting plate 1, an electric slider 4 is provided at the bottom of the electric slide rail 3, an electric hoist 5 is provided at the bottom of the electric slider 4, and a pneumatic gripper 6 is provided at the bottom of the electric hoist 5. All of the above structures are existing technologies. When unpacking small bags, the small bags can be directly unpacked on the ground. When unpacking large bags, they are lifted upside down by the pneumatic gripper 6 and placed into the hopper 7. For a more detailed understanding of the working principle, please refer to Chinese Patent (Authorization No.: 219383104U). The pneumatic gripper 6 is also existing technology and can be referenced in Chinese Patent (Application No.: 219383104U). 02023151454.9), the pneumatic gripper includes a fixed plate fixed to the bottom of the electric hoist. The bottom of the fixed plate is fixed with two fixed blocks and two telescopic rods (which can be hydraulic cylinders). It also includes two mechanical claws. The waist of the mechanical claws is rotatably connected to the lower end of the fixed plate. A connecting plate is hinged between the outer end of the mechanical claws and the lower end of the piston rod of the hydraulic cylinder. In this way, when the piston rod of the hydraulic cylinder moves down, it can drive the inner end of the mechanical claws to rotate upward to grip the packaging bag. Conversely, when the piston rod of the hydraulic cylinder moves up, it can unlock the packaging bag. The pneumatic gripper 6 is existing technology. Other gripping methods can also be used, which will not be described in detail in this utility model. A truncated cone-shaped hopper 7 is provided below the mounting plate 1. A connecting rod 8 is fixed between the outer side of the hopper 7 and each support rod 2.

[0021] like Figure 1-4 As shown, the most significant design difference between this utility model and the prior art is that: the lower end of the hopper 7 is fixedly connected to a bag-unlocking tube 9, and the bag-unlocking tube 9 is provided with a plurality of equally spaced isolation bag-unlocking structures, there are six isolation bag-unlocking structures, each of which includes an insertion hole 9-1 opened on the bag-unlocking tube 9, and a detachable protective glove 10 is installed in the insertion hole 9-1. The protective glove 10 can be made of acid and alkali resistant rubber material, making it more flexible when unlocking bags.

[0022] like Figure 4As shown, in order to make the protective glove 10 detachable, the insertion hole 9-1 is a threaded hole, and an external threaded ring 11 is installed in the internal thread of the insertion hole 9-1. The arm end of the protective glove 10 is fixed on the inner ring surface of the external threaded ring 11, and the finger end extends into the unpacking tube 9.

[0023] like Figure 5 As shown, in order to prevent the external threaded ring 11 from being screwed into the unscrewing tube 9, the inner end of the insertion hole 9-1 extends inward to form a protrusion 9-2.

[0024] like Figure 3 As shown, in order to facilitate the placement of scissors and the cut sealing line, a horizontally placed placement net 12 is fixed on the inner wall of the unpacking tube 9, and a placement groove 12-1 is provided on the top of the placement net 12.

[0025] The working principle of this utility model is explained in detail below: The protective glove 10 is inserted into the unpacking tube 9 through the insertion hole 9-1. The external threaded ring 11 is screwed into the insertion hole 9-1 to install the protective glove 10. The protrusion 9-2 can block the external threaded ring 11. If scissors are needed for unpacking, a pair of scissors can be placed in the placement groove 12-1. After the opening of the large packaging bag is in the unpacking tube 9, the worker inserts their hand through the external threaded ring 11 into the protective glove 10 to unpack the large packaging bag. The bag can be unpacked directly with scissors or by hand. The material falls out through the unpacking tube 9. The placement net 12 prevents excessive material accumulation in the placement groove 12-1. If a sealing line is generated during unpacking, the removed sealing line can be placed directly in the placement groove 12-1. The sealing line will not fall out of the unpacking tube 9 with the material. When there are too many sealing lines in the placement groove 12-1, they can be removed from the top of the unpacking tube 9 through the sealing line.

[0026] Finally, the most significant contribution of this invention compared to existing technologies is that the isolated bag-opening structure prevents workers' hands from coming into contact with materials when opening large packaging bags, thus preventing corrosive materials, such as powdered sodium hydroxide, from falling on them and causing injury. Furthermore, the protective glove 10 can seal the insertion hole 9-1 to prevent materials from splashing out of the insertion hole 9-1.

[0027] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
