Therefore, they should not be construed as limitations of this utility model.
[0023] like Figure 1 As shown, one embodiment of the present invention provides a dispensing device, including a housing 100 and at least one fixing device 200 disposed on the housing 100; the fixing device 200 is provided with a clamping space 210 for clamping a dispensing container, the fixing device 200 includes an adjusting member 220 retractably disposed in the clamping space 210, the adjusting member 220 abuts against the dispensing container in the clamping space 210, and the adjusting member 220 is used to adjust the maximum dosage capacity of the dispensing container during retraction.
[0024] In this embodiment, the dispensing device is used to dispense a formulation into a dispensing tube assembly. The dispensing tube assembly may include at least one dispensing container and a dispensing line communicating with the dispensing container. The formulation can flow into the dispensing container through the dispensing line. The dispensing container may be a container made of flexible material, such as a liquid bag. The dispensing container is clamped by the fixing device 200 and located in the clamping space 210. The adjusting member 220 abuts against the dispensing container in the clamping space 210 and compresses or expands the dispensing container through telescopic movement, thereby adjusting the maximum formulation capacity that can be contained in the dispensing container.
[0025] Understandably, the dispensing containers may include dispensing containers for normal use and dispensing containers for quality inspection. Correspondingly, the fixing device 200 may include a first fixing device for installing dispensing containers for normal use and a second fixing device for installing dispensing containers for quality inspection, etc. That is, the number and structural shape of the fixing devices 200 can be set according to actual conditions (such as the number, shape, and size of dispensing containers with different uses), as long as the number is greater than or equal to the number of dispensing containers and the corresponding clamping space 210 can be used to install dispensing containers. The position of the fixing devices 200 on the housing 100 can be set according to actual conditions, as long as it corresponds to the position of the dispensing containers. In one embodiment, the position and number of the fixing devices 200 correspond one-to-one with the position and number of the dispensing containers, so that all dispensing containers can be installed on the fixing devices 200. The shape of the end of the adjusting member 220 facing the dispensing container can be cylindrical, spherical, or plate-shaped, as long as it can abut against the dispensing container and compress or expand the dispensing container during the telescopic movement without damaging the dispensing container.
[0026] In the above embodiments of this utility model, the dispensing container is clamped and fixed in the clamping space 210 by the fixing device 200. The adjusting member 220, which is telescopically arranged in the clamping space 210, abuts against the dispensing container, so that the adjusting member 220 can adjust the maximum dosage capacity of the dispensing container during telescopic movement, thereby realizing the control of the dispensing volume and improving the accuracy of dosage dispensing. In addition, when the adjusting member 220 is telescopically extended by the same amount, multiple dispensing containers with the same shape installed on the fixing device 200 can maintain the same maximum dosage capacity, which has high repeatability and consistency and improves the efficiency of dosage dispensing.
[0027] like Figure 1 As shown, in one embodiment, the dispensing equipment further includes a detection and control device 300 disposed on the housing 100; the detection and control device 300 is used to install a dispensing pipeline communicating with the dispensing container, and to detect and control the liquid flow rate in the dispensing pipeline. Understandably, the formulation can flow into the dispensing container through the dispensing pipeline, which is mounted on the detection and control device 300. The detection and control device 300 detects the liquid flow rate in the dispensing pipeline and controls the on / off state and opening size of the dispensing pipeline, thereby controlling the volume of the formulation flowing into the dispensing container, and thus improving the accuracy of formulation dispensing.
[0028] like Figure 1As shown, in one embodiment, the detection and control device 300 includes a switching valve 310 and a bubble sensor 320 disposed on the housing 100. The bubble sensor 320 is used to install the dispensing pipeline and detect the liquid flow rate in the dispensing pipeline, wherein detecting the liquid flow rate includes detecting whether liquid flows through the dispensing pipeline. The switching valve 310 is used to install the dispensing pipeline and control the on / off state and opening size of the dispensing pipeline, thereby controlling the liquid flow rate entering the dispensing container from the dispensing pipeline. Further, the switching valve 310 can be a clamp valve, which controls the on / off state and opening size of the dispensing pipeline by clamping it. The number of bubble sensors 320 can be set according to actual conditions. For example, one can be set before and after the switching valve 310 to avoid the switching valve 310 affecting the liquid volume when opening and closing; or multiple bubble sensors 320 can be set and the average value calculated to improve the detection accuracy of liquid flow rate. In this embodiment, the automatic control of formulation dispensing can be achieved through the cooperation of the switching valve 310 and the bubble sensor 320.
[0029] like Figure 1 As shown, in one embodiment, the fixing device 200 includes a mounting plate 230 mounted on the housing 100 and a fixing plate 240 rotatably connected to the mounting plate 230. When the fixing plate 240 rotates to be in contact with the mounting plate 230, a clamping space 210 is formed between the fixing plate 240 and the mounting plate 230. Understandably, the mounting plate 230 is used to position and mount the dispensing container. The fixing plate 240 and the mounting plate 230 can be connected by a pivot. The fixing plate 240 rotates about the pivot in a direction away from the mounting plate 230, thereby opening the clamping space 210. After the dispensing container is positioned and mounted on the mounting plate 230, the fixing plate 240 rotates about the pivot to be in contact with the mounting plate 230, thereby fixing the dispensing container within the clamping space 210, thus maintaining the stability of the dispensing container, avoiding volume deviation due to shaking, and improving the accuracy and consistency of formulation dispensing.
[0030] like Figure 1As shown, in one embodiment, the adjusting member 220 includes a through hole (not shown) on the mounting plate 230, a drive assembly (not shown) mounted on the mounting plate 230, and an adjusting column 221 passing through the through hole and connected to the drive assembly. One end of the adjusting column 221, away from the drive assembly, extends into the clamping space 210 and abuts against a dispensing container clamped in the clamping space 210. The drive assembly drives the adjusting column 221 to move along the through hole to compress the dispensing container, thereby adjusting the maximum dosage capacity of the dispensing container. Understandably, the drive assembly can be a spring assembly, driving the adjusting column 221 by controlling the extension and retraction of the spring. The drive assembly can also be a motor or a drive cylinder, in which case the maximum dosage capacity of the dispensing container can be precisely controlled by the movement distance of the drive shaft of the drive assembly. Understandably, the drive assembly is configured according to requirements, as long as it can drive the adjusting column 221 to extend and retract along the through hole to adjust the maximum dosage capacity of the dispensing container. The shape of the end of the adjusting column 221 away from the driving component can be columnar, spherical, or plate-shaped, as long as it can abut against the dispensing container and compress or expand the dispensing container during the telescopic movement without damaging the dispensing container.
[0031] like Figure 1 As shown, in one embodiment, the adjusting column 221 includes a column (not shown) passing through the through hole and an abutment portion (not shown) connected to the column and located in the clamping space 210. The abutment portion has an arc-shaped abutment surface (not shown). The adjusting column 221 abuts against the dispensing container through the arc-shaped abutment surface. Understandably, the end of the column away from the abutment portion is connected to the driving assembly. The abutment portion can be spherical or hemispherical, etc. In this case, the arc-shaped abutment surface is spherical, and the arc-shaped abutment surface abuts against the dispensing container, thereby avoiding damage to the dispensing container.
[0032] like Figure 1 As shown, in one embodiment, the fixing device 200 further includes a rotating buckle 250 rotatably connected to the mounting plate 230. The rotating buckle 250 is used to engage with the fixing plate 240 when the fixing plate 240 is rotated to fit against the mounting plate 230. Understandably, after the rotating buckle 250 is opened, the fixing plate 240 can rotate relative to the mounting plate 230. At this time, the dispensing container can be installed in the opened clamping space 210. After the dispensing container is installed, when the fixing plate 240 is rotated to fit against the mounting plate 230, the rotating buckle 250 rotates to engage with the fixing plate 240, thereby fixing the dispensing container between the mounting plate 230 and the fixing plate 240.
[0033] like Figure 1 As shown, in one embodiment, the fixing plate 240 and / or the mounting plate 230 are provided with an observation window 260 for observing the dispensing container held in the clamping space 210. It can be understood that the observation window 260 can be a through hole provided on the fixing plate 240 and / or the mounting plate 230, or the observation window 260 can be a transparent plate mounted on a through hole provided on the fixing plate 240 and / or the mounting plate 230, thus allowing observation of the dispensing process of the formulation in the dispensing container.
[0034] like Figure 1 As shown, in one embodiment, the fixing device 200 further includes a positioning post 270 disposed on the mounting plate 230. The positioning post 270 is located in the clamping space 210 and is used to insert into a positioning hole on the dispensing container to position the dispensing container. Understandably, the positioning post 270 is used for positioning and pre-fixing the dispensing container. The positioning post 270 ensures that the dispensing container installed on the fixing device 200 maintains the same position each time, improving the repeatability and consistency of formulation dispensing, thereby improving the efficiency of formulation dispensing.
[0035] like Figure 1 As shown, in one embodiment, the clamping space 210 includes a plurality of clamping slots; the dispensing container includes at least one liquid bag, and all the liquid bags of the dispensing container are clamped one-to-one in the plurality of clamping slots. It can be understood that the position and number of the clamping slots correspond one-to-one with the position and number of the liquid bags, so that all liquid bags can be installed in the clamping slots. In one embodiment, the liquid bag may include a normally used dispensing liquid bag and a quality inspection liquid bag. The clamping slots correspond to clamping slots for clamping dispensing liquid bags and clamping slots for clamping quality inspection liquid bags. For example: Figure 1 As shown, a clamping slot can be provided, including one clamping slot for holding the quality inspection liquid bag, and four sets of five clamping slots per group for holding the dispensing liquid bags.
[0036] The above are merely embodiments of the packaging equipment of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
