Description

Technical Field

[0001] The utility model relates to the technical field of microcapsule manufacturing, in particular to a motion device for controlling microcapsule production. Background Art

[0002] Microcapsules are widely used in the food, pharmaceutical, and cosmetics industries. During the production process, microcapsule production equipment introduces the external and internal phase materials separately and simultaneously drips them out of a dripping tube, forming a microcapsule state in which the external phase material encapsulates the internal phase material. The dripping tube drips the microcapsules into a coagulating liquid, causing it to solidify. The microcapsule production equipment continuously produces microcapsules in the coagulating liquid and intermittently screens the microcapsules from the coagulating liquid. Therefore, the dripping tube and related structures connected to the microcapsule production equipment are located above the coagulating liquid tank containing the coagulating liquid. The collection tank is located within the coagulating liquid tank, facilitating the intermittent collection of solidified microcapsules.

[0003] After microcapsule production is completed, the equipment needs to be cleaned promptly to remove any materials adhering to the interior of the equipment. Once the equipment is clean, production may need to resume immediately. Because microcapsule production equipment is small and difficult to clean manually, automated cleaning is required. This is accomplished by injecting cleaning liquid into the production equipment. Cleaning takes a while, and the cleaning liquid is collected in a waste tank during the cleaning process. Currently, microcapsule production equipment has certain limitations in the automated switching between the cleaning and production processes, resulting in insufficient production efficiency and flexibility.

[0024] The present invention will be further described and illustrated below in conjunction with specific embodiments and accompanying drawings. The embodiments are merely exemplary of the present invention and do not limit its scope.

[0025] The utility model provides a motion device for controlling the production of microcapsules (hereinafter referred to as the motion device), such as Figure 1 As shown, it mainly includes a bracket, a connecting piece, a transmission device, a sensor device, and a microcapsule production device 8.

[0026] The entire motion mechanism is mounted within the microcapsule production equipment via four connectors, which act as Z-axis limiters. In actual production, the motion mechanism only provides motion along the X and Y axes, while the Z axis (perpendicular to the X and Y planes) remains fixed.

[0027] The bracket is composed of four aluminum profiles 1, and aluminum materials of European standard 3030 can be selected for all of them. The bracket includes three fixed brackets 101 and one moving bracket 102. According to an embodiment of the present invention, two of the three fixed brackets 101 have a length of 460 mm and serve as the left and right sides of the bracket, and one has a length of 340 mm and serves as the front side of the bracket; the moving bracket 102 is used to install and carry the microcapsule production device 8, and the length of the moving bracket 102 can be set to 340 mm. The three fixed brackets 101 enclose the moving space of the moving bracket 102.

[0028] The connecting piece includes a connecting plate 2, a T-shaped nut 5, and a screw. There are holes 4 on the connecting plate 2. The fixed brackets 101 are connected to each other or the fixed brackets 101 are connected to the transmission device through the connecting plate 2. Threaded connection is adopted, and each screw is used in cooperation with the corresponding hole 4 and nut on the connecting plate 2. Among them, the connection and fixation between the fixed brackets 101 rely on the T-shaped nut 5 and the hexagon screw. Between the moving bracket 102 and the fixed bracket 101, a slider 3 and a slide rail 301 are added on the basis of the connecting piece. The slide rail 301 is located on the fixed bracket 101 and is symmetrically distributed on the two fixed brackets on the left and right of the moving device. The slider 3 is fixed at both ends of the moving bracket 102. The slider 3 is slidably matched with the slide rail 301. The combination of the slider 3 and the slide rail 301 can select the model RSEB-H13-L420 of Misumi Corporation. The moving bracket 102 and the fixed bracket 101 are connected by sliding, so that the moving bracket 102 can move freely back and forth relative to the fixed bracket 101.

[0029] The transmission device includes two gears 9, two motors 10, two synchronous belt pulleys 12, eight driven wheels (four first driven wheels 11, two second driven wheels 14, and two third driven wheels 15), and one synchronous belt 13. The two gears 9 are installed on the output shafts of the motors 10 and are meshed with the synchronous belt 13. When the two motors 10 are started, the two gears 9 fixed on them drive the synchronous belt 13 to move. Relying on the meshing action between the synchronous belt 13 and the teeth of the two synchronous belt pulleys 12 on the moving bracket 102, the moving bracket 102 is driven to move back and forth. The synchronous belt pulleys 12 are gears that can be meshed with the synchronous belt 13. There are two synchronous belt pulleys 12 in total, which are installed at the left and right ends of the moving bracket 102. The driven wheels (including 11, 14, 15) are smooth rotating wheels and play a role in turning. Figure 1Taking the left side of the device shown as an example: Two first driven wheels 11 are installed at the left front end of the transmission device, one third driven wheel 15 is installed at the left end of the moving bracket 102, and one second driven wheel 14 is installed at the left rear end of the transmission device; the transmission device is a symmetric structure, and a total of eight driven wheels are included in the entire transmission device, symmetrically distributed on both the left and right sides of the moving device. The synchronous belt 13 is connected to two gears 9, two synchronous belt pulleys 12, and eight driven wheels through the CoreXY motion mechanism to achieve motion in the X-axis and Y-axis directions on the horizontal plane. The connection method and control method are as Figure 3 shown.

[0030] The microcapsule production device 8 is fixedly connected to the slot slider 6 through threaded holes and screws. The slot slider 6 forms a sliding connection with the guide rail 7 installed on the moving bracket 102. The guide rail 7 can select the model RSEB-H13-L330 of Misumi Corporation; the guide rail 7 is fixedly connected to the moving bracket 102 by threaded connection. In particular, the slot slider 6 includes a tooth segment meshing with the synchronous belt; during movement, the synchronous belt 13 drives the slot slider 6 to move on the guide rail, and then drives the microcapsule production device to move left and right relative to the moving bracket. There is a channel inside the microcapsule production device 8, and raw materials are transported to the microcapsule production device 8 through pipelines. At the discharge port of the microcapsule production device 8, two raw materials, the internal phase and the external phase, form capsules through a dropping tube and drip downward.

[0031] The forward and backward movement (Y-axis) of the moving bracket and the left and right movement (X-axis) of the microcapsule production device relative to the moving bracket, after the two are superimposed, show that the microcapsule production device as a whole can move to any point on the position coordinates. The position coordinates refer to the positions that the microcapsule production device can reach after X and Y-axis movements within the area where the fixed bracket is located. Taking a certain point as the coordinate origin, the position coordinates of this area are thus formed.

[0032] The sensing device includes two limiters, corresponding to the X-axis limiter 16 and the Y-axis limiter 17 respectively, as Figure 2 shown. The two limiters are fixed to the connecting plate 2 connected to the slider 3 by hot melt adhesive. When the moving bracket 102 moves forward and backward to the limit (unable to move in the same direction anymore), the Y-axis limiter 17 is pressed; when the microcapsule production device 8 moves left and right to the limit (unable to move in the same direction anymore), the X-axis limiter 16 is pressed; taking the point where the X-axis limiter 16 and the Y-axis limiter 17 are simultaneously pressed as the coordinate origin, the control method of the CoreXY motion mechanism is used to control the rotation directions of the two motors 10, thereby controlling the forward and backward movement of the moving bracket 102 and controlling the left and right movement of the microcapsule production device 8, realizing the movement of the microcapsule production device 8 in the X-axis and Y-axis directions. The control method of the CoreXY motion mechanism belongs to an existing and mature motion coordinate control method, as Figure 3 shown.

[0033] Within the area where the fixed support is located, area A and area B are respectively demarcated. Area A is used for producing and collecting microcapsules and is provided with a collection tank, while area B is used for collecting waste liquid during cleaning and is provided with a waste liquid tank. In one implementation, the coordinates of area A are set as (150, 330), and the coordinates of area B are set as (150, 200). By controlling the movement of the microcapsule production device 8 to the coordinates of area A, that is, above the production and collection area, microcapsules can be produced. By controlling the movement of the microcapsule production device 8 to the coordinates of area B, the microcapsule production device 8 and the corresponding pipelines connected to the microcapsule production device 8 can be cleaned. The specific movement is as follows: The transmission device drives the microcapsule production device 8 to move to the coordinates of the collection tank in area A (150, 330), and then starts production. Microcapsules are collected in the collection tank. After being filled, the microcapsule preparation is stopped, and then the microcapsule production device 8 is driven to move to the coordinates of the waste liquid tank in area B (150, 200). Then, the entire pipeline of the equipment and the microcapsule production device are cleaned, and the generated cleaning waste liquid is collected in the waste liquid tank. Therefore, this movement device realizes the movement and position switching of the microcapsule preparation equipment in two different production operation stages of production and cleaning, thus better meeting the requirements of actual production.
