Description

Technical Field

[0001] The invention relates to a device installed in a confidential carrier collection cabinet and used for automatically sealing a confidential carrier collection bag. Background Art

[0002] Before discarding, carriers that store confidential information, such as paper, hard disks, CDs, and USB flash drives, need to be destroyed to prevent confidential information from being leaked. There are two common destruction methods: one is that confidential units purchase multifunctional destruction machines, which crush confidential carriers into irreparable debris; the other is to put confidential carriers into an automatic collection cabinet, and have a dedicated person regularly take out the collection bags in the collection cabinet and hand them over to the destruction center for centralized destruction.

[0003] Since the confiscation bags are ordinary plastic bags, they are sealed by manually tying them with ropes. The disadvantages of this sealing method are: 1. When the confiscation bags are sealed, the confidential carriers to be destroyed are often secretly taken away or "switched" due to lack of supervision or lax supervision; 2. In the process of transferring the confiscation bags from the collection cabinet to the destruction center, they are likely to be opened without being noticed, and the confidential carriers inside may be lost or "switched", causing the leakage of confidential information and posing a security risk. Summary of the invention

[0039] The structure and features of the present invention are described in detail below in conjunction with the accompanying drawings and embodiments. It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be regarded as limiting the present invention, but are merely examples of embodiments, the purpose of which is to make the features of the present invention obvious.

[0040] like Figure 1-Figure 3 As shown, a container 1 is arranged below the input port of the collection cabinet, and a collection bag 2 for containing confidential carriers is sleeved in the container 1. The automatic sealing device for collecting bags of confidential carriers of the present invention comprises a bag hanging structure 3 and a heat sealing mechanism 4. The bag hanging mechanism 3 is an expandable and foldable multi-link frame, which is used to compress the collection bag 2, and the bag hanging mechanism 3 is detachably mounted on the top of the heat sealing mechanism 4. Driven by the heat sealing mechanism 4, the bag hanging mechanism 3 is folded to close the opening of the collection bag 2, and at the same time, the heat sealing mechanism 4 is actuated to heat-melt-seal the opening of the closed collection bag 2.

[0041] like Figure 4 , Figure 5 As shown, the bag hanging mechanism 3 includes a left bag hanging bottom plate 31, a right bag hanging bottom plate 32, an upper left connecting rod 33, an upper right connecting rod 34, a lower left connecting rod 35, a lower right connecting rod 36, a left bag hanging pressure plate 37 and a right bag hanging pressure plate 38.

[0042] The upper left connecting rod 33 and the upper right connecting rod 34 are pivotally connected by the connecting rod rotating shaft 39 to form an upper frame; the lower left connecting rod 35 and the lower right connecting rod 36 are pivotally connected by the connecting rod rotating shaft 39 to form a lower frame; the two ends of the upper frame are pivotally connected to the head of the left bag hanging bottom plate 31 and the right bag hanging bottom plate 32 through the connecting rod rotating shaft 39 respectively; the two ends of the lower frame are pivotally connected to the tail of the left bag hanging bottom plate 31 and the right bag hanging bottom plate 32 through the connecting rod rotating shaft 39 respectively, forming an expandable and foldable multi-connecting rod frame structure, and the frames constituting the bag hanging mechanism rotate with each other through the connecting rod rotating shaft 39.

[0043] The left bag pressing plate 37 is located above the left bag bottom plate 31, and one end of the left bag pressing plate 37 is pivotally connected to the left bag bottom plate 31 through the pressing plate rotating shaft 310. The right bag pressing plate 38 is located above the right bag bottom plate 32, and one end of the right bag pressing plate 38 is pivotally connected to the right bag bottom plate 32 through the pressing plate rotating shaft 310. When in use, first lift the left and right bag pressing plates 37, 38; place the edge of the collection bag between the left and right bag pressing plates 37, 38 and the left and right bag bottom plates 31, 32; press the left and right bag pressing plates 37, 38 downwards, and press the edge of the collection bag through the left and right bag pressing plates and the left and right bag bottom plates to hold the collection bag.

[0044] To further tighten the edge of the collection bag, Figure 4 , 5 As shown, the present invention has a plurality of protrusions 311 arranged at intervals on the upper surfaces of the left and right hanging bag bottom plates 31, 32, and grooves arranged on the backs of the left and right hanging bag pressing plates 37, 38. A plurality of through holes are arranged at intervals on the edge of the opening of the collection bag, and the through holes at the edge of the collection bag are hung on the protrusions 311 on the left and right hanging bag bottom plates, and then the left and right hanging bag pressing plates 37, 38 are pressed downwards to make the protrusions 311 on the left and right hanging bag bottom plates fit into the grooves on the backs of the left and right hanging bag pressing plates.

[0045] In addition, the present invention provides buckles 312 at the ends of the left and right bag hanging pressure plates 37, 38, and correspondingly, through holes are provided at the ends of the left and right bag hanging bottom plates 31, 32. When the left and right bag hanging pressure plates are pressed downward, the buckles 312 at the ends of the left and right bag hanging pressure plates are inserted into the through holes at the ends of the left and right bag hanging bottom plates, so that the left and right bag hanging pressure plates 37, 38 and the left and right bag hanging bottom plates 31, 32 further press the collected bags.

[0046] like Figure 4 , Figure 5 As shown, the present invention further welds a bag guide rod 314 below the connecting rod shaft 39 where the upper left connecting rod 33 and the upper right connecting rod 34 are pivotally connected. The bag guide rod 314 is inserted into the side wall of the collection bag. Figure 2 , 3 As shown, when the confiscation bag is full of debris, the heat sealing mechanism 4 drives the bag hanging mechanism 3 to fold and seal the confiscation bag 2, and the bag guide rod 314 can pull the confiscation bag to be sealed smoothly.

[0047] When the bag 2 is sealed by the bag folding and hanging mechanism 3, in order to make the bag opening fold more smoothly, Figure 6 As shown, at the connection points between the two ends of the right bag bottom plate 32 and the upper and lower right connecting rods 34 and 36, the right bag bottom plate 32 has an inward angle of a circular chamfer 315 and an outward angle of a sharp angle 316. In this way, when the upper and lower right connecting rods rotate around the connecting rod rotating shaft 39, the upper and lower right connecting rods are limited by the structures of the circular chamfer 315 and the sharp angle 316 and can only rotate inward in one direction but cannot rotate outward. Similarly, at the connection points between the two ends of the left bag bottom plate 31 and the upper and lower right connecting rods 33 and 35, the left bag bottom plate 31 has an inward angle of a circular chamfer and an outward angle of a sharp angle. This design makes the sealing of the collection bag more beautiful and smooth.

[0048] For ease of operation, Figure 4 , 5 As shown, in the present invention, handles 317 are further provided at the ends of the left and right bag hanging bottom plates 31, 32.

[0049] To prevent confidential information from being leaked due to loss of contents, replacement of packages, or secondary opening of the confiscation bag during transportation after the confiscation bag is taken out of the confiscation cabinet, such as Figure 1-Figure 3 As shown, the present invention has a heat sealing mechanism 4 installed on the top of the container 1. Before the confiscation bag is taken out of the confiscation cabinet, the heat sealing mechanism 4 directly heat-melts and seals the opening of the confiscation bag 2 in the confiscation cabinet.

[0050] like Figure 7-Figure 11 As shown, the heat sealing mechanism 4 is composed of two heat sealing units with bilateral symmetry and the same structure, and the two heat sealing units are fixed on the side wall of the container 1 through a U-shaped mounting plate 41, and the top edge of the mounting plate 41 is flush with the top edge of the container 1. Each heat sealing unit includes a bracket 42, a rotating plate 43, a rotating plate electric push rod 44, a heat sealing knife 45 and a heat sealing knife electric push rod 46.

[0051] The bracket 42 is located at the top of the side wall of the container 1 and is fixedly connected to the mounting plate 41; the two ends of the rotating plate 43 are fixed to the inner side of the bracket 42 through the rotating shaft 47, and can be turned in the container 1 along the axis of the rotating shaft 47. Two miniature rotating plate electric push rods 44 are fixed on the left and right side walls of the U-shaped mounting plate 41. Fig.11 As shown, the top of the rotating plate electric push rod 44 is connected to a connecting piece 441, one end of the connecting piece 441 is connected to the rotating plate electric push rod 44 through a pin 442, and the other end is connected to the rotating plate 43 through a pin 443. When the micro rotating plate electric push rod 44 moves upward, it pushes the rotating plate 43 to turn 90 degrees around the rotating shaft 47 into the container 1, as shown in FIG. Fig. 9 When the micro-turn plate electric push rod 44 moves downward, the push rod pulls the connecting member 441 downward, causing the turn plate 43 to rotate 90° outward around the shaft 47 to open, as shown Figure 7 shown.

[0052] The length of the rotating plate 43 is equal to the length of the container 1 , and the width thereof is equal to one half of the width of the container 1 .

[0053] Two miniature heat-sealing knife electric push rods 46 are symmetrically fixed on the rotating plate 43. A heat-sealing knife 45 is fixedly connected to the top of the two heat-sealing knife electric push rods 46. The heat-sealing knife 45 is connected to the power supply through a power switch. When the left and right rotating plates 43 are turned over 90 degrees, the heat-sealing knife electric push rods 46 are activated to push the heat-sealing knife 45 on the rotating plate to the middle position of the container 1. When the heat-sealing knife 45 on the left and right rotating plates moves to the middle position of the container, the heat-sealing knife 45 is electrified and heats up to heat-melt and seal the opening of the confiscated bag 2.

[0054] In order to heat-seal the opening of the collection bag, the collection bag hanging mechanism 3 needs to move toward the middle of the container together with the heat-sealing mechanism 4. Fig. 12A , Fig. 12B As shown, the bag hanging mechanism 3 is detachably mounted on the top of the heat sealing mechanism 4. Fig.13 , Fig.14 As shown, a dovetail-shaped slide groove 48 is fixed on the top of the left and right rotating plates 43, and a long dovetail-shaped slide bar 318 is fixed on the top of the left and right frames of the bag hanging mechanism 3. The dovetail-shaped slide bar 318 is inserted into the dovetail-shaped slide groove 48, and the dovetail-shaped slide bar 318 is slid, so that the bag hanging mechanism 3 and the heat sealing mechanism 4 are fixed together. Since the upper, lower, left and right frames constituting the bag hanging mechanism 3 are pivotally connected to each other through a rotating shaft, and the upper and lower frames are pivotally connected by two connecting rods, when the rotating plate electric push rod 44 pushes the rotating plate 43 to turn over into the container, the bag hanging mechanism 3 drives the collection bag 2 to be folded (such as Figure 3 shown).

[0055] The present invention also includes a heat sealing electric control box 49 and a group of micro switches 410. The heat sealing electric control box 49 is fixed on the U-shaped mounting plate 41, and the micro switches 410 are installed at the middle position of the upper frame and / or the lower frame of the top edge opening of the container 1.

[0056] A control circuit board is installed in the heat sealing electric control box, and a microprocessor is installed on the circuit board. The control signal output end of the microprocessor is connected to the control end of the rotating plate electric push rod and the heat sealing knife electric push rod respectively, and controls the movement of the micro rotating plate electric push rod 44 and the micro heat sealing knife electric push rod 46. The control signal output end of the microprocessor is also connected to the power control end of the heat sealing knife 45 to control the power-on heating of the heat sealing knife 45. The signal output end of the micro switch 410 is connected to the signal input end of the microprocessor, and the position signal of the rotating plate 43 is fed back to the microprocessor.

[0057] When the confiscation bag is full of confidential carriers or the staff needs to take the confiscation bag away, the heat sealing mechanism 4 is started, and the microprocessor in the heat sealing electric control box 49 outputs a control signal to activate the rotating plate electric push rod 44, push the rotating plate 43 to turn over into the container 1, and drive the bag hanging mechanism 3 to move to the middle position of the container 1 to fold and close the opening of the confiscation bag 2; when the rotating plate 43 turns over and hits the micro switch 410, it means that the rotating plate 43 has turned over 90°, and the microprocessor in the heat sealing electric control box outputs a control signal, and the rotating plate electric push rod 44 stops moving; at the same time, the microprocessor outputs a control signal to make the heat sealing knife The electric push rod 46 moves to push the heat sealing knife 45 to move to the middle position of the top of the container. When the heat sealing knife touches the micro switch 410, the microprocessor outputs a control signal, the heat sealing knife electric push rod stops moving, the heat sealing knife 45 is electrified and heated, and the opening of the collection bag 2 is heat-melted and sealed; after the heat sealing knife 45 is powered on for 5-10 seconds and the collection bag 2 is sealed, the microprocessor outputs a control signal to cut off the power of the heat sealing knife 45, and the heat sealing knife electric push rod 46 moves in the opposite direction to retract the push rod, and the heat sealing knife 45 is retracted; the bag hanging mechanism 3 is removed from the heat sealing mechanism together with the collection bag 2 after the bag mouth is closed (such as Figure 3 As shown), the long dovetail slide of the bag hanging mechanism 3 is pulled out from the dovetail slide groove at the end of the rotating plate; the microprocessor outputs a control signal to make the rotating plate electric push rod 44 move in the opposite direction, and the rotating plate 43 opens.

[0058] The invention has the advantage that the opening of the collection bag can be automatically sealed, thereby ensuring the safety of the confidential carrier and reducing the risk of leakage.

[0059] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
