Description

Technical Field

[0001] This utility model relates to the field of correction fluid packaging box opening technology, specifically a correction fluid packaging box opening machine. Background Technology

[0002] Correction fluid is generally a liquid and is easily affected by external environmental factors such as temperature, humidity, or light, leading to changes in quality or leakage. Therefore, cardboard boxes, as packaging materials, primarily serve the functions of protection, storage, and transportation. A carton opener is an automated packaging device whose main function is to automatically unfold stacked standard cardboard boxes into a predetermined shape, facilitating the storage of items such as medicine bottles and other similar items. When placing and transporting correction fluid, cardboard boxes can neatly package the bottles, making transportation and distribution convenient.

[0003] A carton opening machine, such as one disclosed in CN222728380U, includes a frame and a transfer mechanism, a carton opening mechanism, and a carton folding mechanism mounted on the frame. The frame has a storage area for storing cartons to be opened. The transfer mechanism removes the cartons from the storage rack and moves them to the opening position, making them fully open. The folding mechanism folds the rear end of the fully open carton to close the opening. The frame also includes a stabilizing component, comprising a first driving member and a stop. The first driving member pushes the stop against the front end of the carton before the folding mechanism folds it. Because the two side tongues at the open end of the carton always stand upright and are in the same position after the carton is upright, the stop can prevent the carton from moving backward during folding, regardless of whether the carton is placed upright or backward, as long as the rear end of the carton is facing correctly. This improves the freedom of carton placement.

[0004] The aforementioned patent proposes that the adsorption assembly includes a receiving plate, a pressure control device, and multiple suction cups. The receiving plate is movably connected to the frame, and the multiple suction cups are detachably connected to the receiving plate. The pressure control device is used to control the air pressure inside the suction cups. The multiple suction cups are located below the box body and adsorb one side of the box body. However, in actual use, the suction cups will gradually wear down during long-term use, especially when they are in constant contact with the surface of the carton. Wear will reduce the sealing performance of the suction cups, and the worn suction cups cannot maintain good contact with the box body being suctioned, resulting in weakened suction.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The present invention discloses a box opening machine for correction fluid packaging boxes.

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-4 A box opener for correction fluid packaging includes a frame 1, an air pump 11 installed inside the frame 1, an installation component 12 installed on one side of the air pump 11 and inside the frame 1, and an adsorption component 13 installed at the upper and lower ends of one side of the installation component 12.

[0023] The adsorption component 13 includes an L-shaped connecting tube 132 and a suction cup 133 installed at one end of the L-shaped connecting tube 132. A negative pressure sensor 135 is installed through the top of the L-shaped connecting tube 132. The negative pressure sensor 135 is an HP Series model. The core function of the negative pressure sensor 135 is to measure the pressure of the gas or liquid (below atmospheric pressure). Through the piezoelectric element, strain gauge, or capacitive element inside the sensor, it can sense changes in negative pressure and convert them into corresponding electrical signals. The sensor converts analog signals into digital signals for subsequent processing and transmission. The sensor transmits data to the IoT controller 2 via Wi-Fi. The IoT controller 2 is installed on the outer surface of the rack 1, near the adsorption component 13. The IoT controller 2 is a LinkIt Smart 7688 model. The IoT controller 2 collects and manages data by connecting multiple sets of negative pressure sensors 135. The negative pressure sensors 135 can transmit data via Wi-Fi. The IoT controller 2 identifies the specific negative pressure sensor 135 according to the device ID, accurately displays which adsorption component 13 has a negative pressure problem, and clearly informs the staff which set of adsorption components 13 needs to be checked. The IoT controller 2 makes a decision based on preset rules or algorithms. When the negative pressure measured by the negative pressure sensor 135 does not exceed the set threshold, the IoT controller 2 can issue a warning through the alarm.

[0024] Mounting component 12 includes a sliding plate 122 and an outer frame 121 mounted on the middle of one side of the sliding plate 122. Mounting grooves 123 are provided at both the upper and lower ends of the sliding plate 122. An mounting tube 131 is mounted on the outer surface of the L-shaped connecting pipe 132 at the end furthest from the suction cup 133. Threaded holes A124 are provided at both the top and bottom ends of the sliding plate 122. A threaded hole B134 is provided on the outer surface of the mounting tube 131, and the threaded hole B134 is aligned with the threaded hole A124. Bolts are used to mount the outer frame 121 to the mounting tube 131.

[0025] The mounting components 12 are provided in two sets, and the adsorption components 13 are provided in four sets. The four sets of adsorption components 13 are installed in pairs at the upper and lower ends of the two sets of mounting components 12, respectively. The four sets of adsorption components 13 are evenly installed at the upper and lower ends of the two sets of mounting components 12 to facilitate the adsorption of the correction fluid packaging box by the adsorption components 13.

[0026] An external threaded tube 136 is installed on the outer surface of the L-shaped connector 132 and at the end near the negative pressure sensor 135. A rubber pad 137 is installed on the outer surface of the external threaded tube 136. An extraction component 14 is installed on the outer surfaces of the external threaded tube 136 and the rubber pad 137. The external threaded tube 136 is connected to the vacuum pump 11 through the extraction component 14.

[0027] In this embodiment: During the process of suction cup 133 adsorbing and picking up the correction fluid packaging box, the air pump 11 operates, and suction cup 133 directly contacts the outer surface of correction fluid packaging box. After the air is extracted between correction fluid packaging box and suction cup 133, air circulates through L-shaped connector 132, external threaded pipe 136 and air extraction hose 141. Negative pressure sensor 135 detects the negative pressure inside the adsorption component 13 and extraction component 14. When the negative pressure detected by negative pressure sensor 135 is lower than that of other adsorption components 13 and extraction components 14, negative pressure sensor 135 transmits the data to IoT controller 2 via Wi-Fi. The display screen of IoT controller 2 shows which adsorption component 13 and extraction component 14 has a problem, and the adsorption component 13 and extraction component 14 can be maintained in time.

[0028] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The extraction component 14 includes a connecting pipe 142 and a rubber ring 143 installed inside the connecting pipe 142. The inner wall of the rubber ring 143 has a threaded groove 144. The rubber ring 143 with the threaded groove 144 is threadedly connected to the outer wall of the external threaded pipe 136 and the rubber pad 137, thus sealing the connection between the adsorption component 13 and the extraction component 14 to prevent air leakage. A sealing ring 145 is installed in the middle of the inner wall of the connecting pipe 142. An air extraction hose 141 is installed inside the sealing ring 145. The sealing ring 145 seals the connection between the air extraction hose 141 and the connecting pipe 142.

[0029] In this embodiment: when a set of adsorption components 13 and corresponding extraction components 14 malfunction, the connecting tube 142 can be rotated by hand. The rubber ring 143 with threaded grooves 144 rotates on the outer surface of the external threaded tube 136, and the connecting tube 142 rotates out from the outside of the external threaded tube 136. The two sets of extraction components 14 installed at the upper and lower ends of the slide plate 122 are swapped. The connecting tube 142 rotates in the opposite direction and is threadedly connected to the outside of another set of external threaded tubes 136. The rubber ring 143 with threaded grooves 144 is connected to the outer surface of the external threaded tube 136. The rubber pad 137 set on the outer surface of the external threaded tube 136 seals the inside of the connecting tube 142. The vacuum pump 11 is restarted, and the extraction component 14 and the corresponding adsorption component 13 are used to adsorb the correction fluid packaging box. The problem is accurately located as to whether the problem is with the extraction component 14 or the adsorption component 13, making it easy to replace the adsorption component 13 or the extraction component 14.
