Abstract
Description
Technical Field
[0001] The present application relates to the field of material collection, and in particular to a material bag closing device. Background Art
[0002] Medical waste collectors play a vital role in the medical and health field. Their main function is to safely and efficiently collect, store and process various medical wastes, including used medical devices, patient secretions, expired medicines, etc. The proper treatment of these wastes is of indispensable importance to prevent the spread of pathogens, protect the environment and public health safety.
[0003] Existing medical waste collectors often use the "gooseneck" knot technology to form an effective seal, that is, to form a tight sealing structure by twisting a part of the garbage bag. However, when the weight or volume of the waste exceeds a certain range, this method is difficult to achieve the expected sealing effect, resulting in insufficient or too small gooseneck structure, which in turn causes the garbage bag to leak. This leakage phenomenon not only reduces the performance of the medical waste collector, but more importantly, affects its safety, because medical waste that is not effectively sealed may become a medium for the spread of pathogens, endangering the environment and public health.

The second end 312 is provided with a "U"-shaped notch 313, and the notch 313 is used to accommodate part of the material bag 200.
[0079] When in use, the bag closing device 100 has a first state X and a second state Y, see Figure 1 In the first state X, when the first bag clamping module 10 is separated from the second bag clamping module 20, the first left clamping component 12, the first right clamping component 13, the second left clamping component 22 and the second right clamping component 23 respectively clamp the four corners of the opening end 201 of the bag 200, so that the opening end 201 of the bag 200 is propped open, thereby facilitating the loading of items into the bag 200, such as medical waste.
[0080] See also Figure 2 and Figure 4 In the second state Y, when the first bag clamping module 10 and the second bag clamping module 20 are attached, the first left clamping assembly 12 and the second left clamping assembly 22 clamp the two corners of the material bag 200, the first right clamping assembly 13 and the second right clamping assembly 23 release the other two corners of the material bag 200, and the first driving member 32 drives the first push rod 31 to push the material bag 200 from the other two corners of the material bag 200, so that the open end 201 gathers and forms a sealing structure 202 (see Fig.6D ).
[0081] The bag closing device 100 provided in the present application arranges the first bag clamping module 10 and the second bag clamping module 20 relatively, and utilizes the pushing action of the bag pushing module 30 so that the open end 201 of the bag 200 can be effectively gathered into a sealing structure 202, which is conducive to bundling. In this way, compared with the traditional gooseneck structure formed by manual twisting, it is tighter and more uniform, and can effectively improve the sealing efficiency and sealing quality, so as to better prevent the spread of pathogens and protect environmental safety. In addition, the automated closing process of the bag 200 reduces the contact between the operator and the medical waste, and reduces the risk of cross infection. In addition, because the sealing of the bag 200 is more reliable, the leakage of the waste bag is reduced, and the safety of the operator and the environment is further protected.

The third end 331 is transmission-connected to the second driving member 34, and the fourth end 332 is used to push the material bag 200. The movement direction of the first push rod 31 is parallel to the movement direction of the second push rod 33, and the fourth end 332 is arranged toward the first end 311.
[0083] In the second state Y, the fourth end 332 is used to push the open end 201 of the material bag 200 from one side of the other two corners to the first predetermined position P1, and the second end 312 is used to push the material bag 200 from the first predetermined position P1 to the second predetermined position P2, so as to form the sealing structure 202. The first predetermined position P1 is located between the first left clamping assembly 12 and the first right clamping assembly 13, and the second predetermined position P2 is located on the side of the first left clamping assembly 12 away from the first right clamping assembly 13.
[0084] See also Figure 3 and Figure 6B In this embodiment, the first driving member 32 includes a first driver 321 and a first screw rod 322. The first driver 321 is connected to one end of the first screw rod 322 by transmission, and the first end 311 is sleeved on the first screw rod 322. The first driver 321 drives the first screw rod 322 to rotate, and the first screw rod 322 is arranged on the first bag clamping module 10 roughly along the second direction B. The outer periphery of the first screw rod 322 is provided with a thread, and the first end 311 is sleeved on the first screw rod 322, and the first end 311 is engaged with the thread on the outer periphery of the first screw rod 322. When the first screw rod 322 rotates in one direction, the first push rod 31 moves toward the second predetermined position P2. When the first screw rod 322 rotates in the opposite direction, the first push rod 31 moves toward the first predetermined position P1. Wherein, the first driver 321 is a stepping motor.
[0085] See also Figure 3 and Figure 6B In this embodiment, the first driving member 32 further includes a first guide rod 323, which extends along the second direction B.

[0088] See also Figure 1 and Figure 4 In this embodiment, the first bag clamping module 10 further includes a stopper 14, and the direction from the first push rod 31 to the first left clamping assembly 12 is defined as a third direction C. The stopper 14 is disposed on the second base 21 between the second push rod 33 and the second left clamping assembly 22 along the third direction C. The stopper 14 is used to hinder the movement of the material bag 200, and reduce the first push rod 31 from pulling the material bag 200 out of the first left clamping assembly 12 and the second left clamping assembly 22.
[0089] See also Figure 1 and Figure 3In this embodiment, the first left clamping assembly 12 includes a first material rolling wheel 121, a second material rolling wheel 122 and a rolling wheel driver 123. The first base 11 is provided with a groove 111, and the first material rolling wheel 121, the second material rolling wheel 122 and the rolling wheel driver 123 are all accommodated in the groove 111. The first material rolling wheel 121 and the second material rolling wheel 122 are arranged opposite to each other. The rolling wheel driver 123 is connected to the first material rolling wheel 121 and the second material rolling wheel 122 by transmission, so as to drive the first material rolling wheel 121 and the second material rolling wheel 122 to rotate. For example, the first material rolling wheel 121 rotates forward, and the second material rolling wheel 122 rotates reversely. There is a gap S between the first material rolling wheel 121 and the second material rolling wheel 122, and the gap S is used to clamp a corner of the material bag 200.

The structures of the first right clamping assembly 13 , the second left clamping assembly 22 and the second right clamping assembly 23 are similar to those of the first left clamping assembly 12 , and are not described in detail herein.
[0090] In this embodiment, the bag closing device 100 generally includes the following steps when in operation:
[0091] S1: See Fig. 6A The first base 11 and the second base 21 gradually change from a spaced-apart state (ie, a first state X, on the left side of the arrow) to a close state (ie, a second state Y, on the right side of the arrow). The opening end 201 of the material bag 200 is closed.
[0092] S2: See Figure 6B The first right clamping assembly 13 and the second right clamping assembly 23 release the two corners of the opening end 201 of the material bag 200, and at the same time, the fourth end 332 of the second push rod 33 pushes the two released corners to move toward the two unreleased corners, that is, toward the first predetermined position P1.
[0093] S3: See Figure 6C , the first push rod 31 continues to push the two released corners to move, so that the four corners of the open end 201 of the material bag 200 are gathered, and the first push rod 31 continues to gather the open end 201, so that the open end 201 is partially pushed out of the first base 11 (i.e., the second predetermined position P2). At this time, the pushed out part of the open end 201 is roughly in a sealed structure 202.
[0094] S4: See Fig.6D, the first push rod 31 is reset and retracted, so that the second end 312 is retracted into the first base 11, and the mechanical arm is used to tie the sealing structure 202 of the open end 201. Finally, the first left clamping assembly 12 and the second left clamping assembly 22 release the other two corners of the open end 201, completing the closing operation of one bag 200.
[0095] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
