Description

Technical Field

[0001] The present application belongs to the field of optical cable production supporting equipment, and more specifically, relates to an automatic batching device for optical cable production. Background Art

[0002] Optical cable is a communication line that uses a certain number of optical fibers to form a cable core in a certain way, which is covered with a sheath and sometimes also covered with an outer sheath to realize the transmission of optical signals.

[0003] During the production process of optical cables, different raw materials must be mixed in a specific ratio to improve product performance. These materials are then used to prepare the cable's inner shell layer or casing. To achieve this mixing, the conventional method is to manually weigh the raw materials before feeding them into a blender for mixing. However, since production equipment operates 24 / 7, the daily mixing volume is very large. Manual operation is not only cumbersome and labor-intensive, but also inconvenient for long-term production. It is also prone to mixing errors due to operational deviations, which can affect product quality. Summary of the Invention

Detailed implementation manners

[0041] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] As Figure 1 shown, an automatic batching device for optical cable production provided by the present application includes a mixing unit 1 and at least two groups of discharging units 2. Each discharging unit 2 is respectively used to quantitatively convey different raw materials for optical cable production to the mixing unit 1, and the mixing unit 1 is used to mix the raw materials evenly. Among them, the raw materials can be solid granular materials such as EVA, PE, and PBT, with a particle size of about 3 mm, and are used to prepare the inner layer of the optical cable skeleton or the sleeve. The number of discharging units 2 is the same as the type of raw materials, and one group of discharging units 2 conveys one type of raw material. If there are two groups, they can be arranged symmetrically on the side of the mixing unit 1.

[0043] As Figure 1 and Figure 2As shown, each feeding unit 2 includes a storage tank 3 and a metering feeding assembly disposed within the storage tank 3. The storage tank 3 can be installed on the ground foundation through a mounting frame (not shown in the figure). The metering feeding assembly is located at the bottom of the storage tank 3 and is used to intermittently convey the raw materials quantitatively from the bottom of the storage tank 3 to the mixing unit 1. Specifically, the metering feeding assembly includes an upper feeding module and a lower discharging module. Among them, the feeding module is used to send the raw materials from the storage tank 3 to the discharging module. The discharging module is located between the feeding module and the bottom of the storage tank 3, and intermittently conveys the raw materials quantitatively from the bottom of the storage tank 3 to the mixing unit 1 through rotational movement.

[0044] More specifically, as Figures 2 - 4 shown, the feeding module includes a feeding plate 4, and the discharging module includes a discharging plate 5. Among them, the feeding plate 4 is fixed on the inner wall of the storage tank 3. A feeding hole 4-1 is provided on the feeding plate 4. The upper surface of the discharging plate 5 is attached to the lower surface of the feeding plate 4, and the lower surface of the discharging plate 5 is attached to the inner bottom surface of the storage tank 3. A storage hole 5-1 is provided on the discharging plate 5, and a discharging hole 3-1 is provided at the bottom of the storage tank 3. Preferably, the storage hole 5-1 is a circular hole with a diameter of 40 cm and a depth (i.e., the thickness of the discharging plate 5) of 2 cm. Specifically, the feeding hole 4-1 and the discharging hole 3-1 are arranged in a staggered manner (i.e., not overlapping vertically). Preferably, the feeding hole 4-1 and the discharging hole 3-1 can be arranged in a 180° staggered manner. Of course, other angles of staggered arrangement can also be selected according to needs. It should be noted that the feeding hole 4-1, the storage hole 5-1, and the discharging hole 3-1 are all through holes.

[0045] Furthermore, in order to ensure that the storage hole 5-1 is filled with materials during the rotation of the discharging plate 5 and the materials in the storage hole 5-1 are discharged during the rotation of the discharging plate 5 (i.e., the raw materials in the storage hole 5-1 are sent into the mixing unit 1 through the discharging hole 3-1), that is, the discharging plate 5 does not stop rotating during storage and discharging, the present application preferably designs the feeding hole 4-1 and the discharging hole 3-1 as long strip-shaped holes, and the size of the long strip-shaped hole is larger than the size of the storage hole 5-1 (i.e., the projected area of the feeding hole on the upper surface of the discharging plate is larger than the projected area of the storage hole on the upper surface of the discharging plate. Similarly, the projected area of the discharging hole on the lower surface of the discharging plate is larger than the projected area of the storage hole on the lower surface of the discharging plate). At the same time, the length direction of the long strip-shaped hole is consistent with the rotation direction of the discharging plate (such as Figure 8 the arrow shown), so as to ensure that the feeding hole 4-1 and the discharging hole 3-1 can cover the storage hole 5-1 during the rotation of the discharging plate 5, and make the raw materials have enough time to fall into the storage hole, and at the same time make the raw materials in the storage hole have enough time to fall into the mixing unit. As Figure 3 and Figure 6 shown, the long strip-shaped hole can be an arc-shaped hole, a rectangular hole, etc.

[0046] As Figure 9As shown in the figure, the relative positions of the feed hole 4-1, the material storage hole 5-1 and the discharge hole 3-1 are shown. The feed hole 4-1 and the discharge hole 3-1 are arranged symmetrically with a 180° dislocation. One of the material storage holes 5-1 is exactly below the feed hole 4-1, and the other material storage hole 5-1 arranged symmetrically with this material storage hole 5-1 is exactly above the discharge hole 3-1. The areas of the feed hole 4-1 and the discharge hole 3-1 are both larger than the area of a single material storage hole 5-1. The lengths of the feed hole 4-1 and the discharge hole 3-1 extend along the rotation direction of the discharge plate 5 and are preferably not to cover the adjacent material storage holes 5-1. The specific design of the relative positions of the feed hole 4-1, the discharge hole 3-1 and the material storage hole 5-1 can be set according to actual needs, and this application will not elaborate too much.

[0047] In this application, the discharge plate 5 can rotate relative to the feed plate 4 so that the material storage hole 5-1 can be intermittently communicated with the feed hole 4-1 and the discharge hole 3-1 up and down. When the material storage hole 5-1 is communicated with the feed hole 4-1, the raw materials in the storage tank 3 are sent into the material storage hole 5-1 through the feed hole 4-1 and fill the material storage hole 5-1. When the material storage hole 5-1 is communicated with the discharge hole 3-1, the raw materials in the material storage hole 5-1 are sent into the mixing unit 1 through the discharge hole 3-1. Since the sizes of the material storage holes 5-1 are fixed values, the volumes of the raw materials stored in the material storage holes 5-1 are also fixed values (due to factors such as the shape of the raw materials, there may be a slight error, but within the acceptable range of production errors, it does not affect the product quality). Therefore, the discharge amount of the raw materials can be controlled by controlling the rotation speed of the discharge plate 5, so as to achieve the purpose of automatic proportioning and mixing. Since the upper surface of the discharge plate 5 fits with the lower surface of the feed plate 4, during the rotation of the discharge plate 5, the hole wall at the position where the feed hole 4-1 is opened on the feed plate 4 can also act as a scraping plate to further ensure that the volume of the raw materials filled in the material storage hole 5-1 each time is consistent. The discharge amounts of the respective discharging units 2 can be set in advance according to the raw material ratio, that is, according to the number of the material storage holes 5-1 opened and the required amount of raw materials, the rotation speed and rotation time of the discharge plate 5 are set to ensure that the discharge amounts of the respective discharging units 2 meet the proportioning requirements. Specifically, how to set the rotation speed and rotation time of the discharge plate 5 can be set by those skilled in the art according to the design common sense in this field, and this application will not elaborate here.

[0048] Of course, the rotation speed of each discharge plate 5 is adjustable. The faster the rotation speed, the faster the discharge. However, it is necessary to comprehensively consider whether the storage holes can be filled with materials and emptied. Generally, the rotation speeds of the discharge plates are the same, and the speed is set at 3 to 8 revolutions per minute (too fast rotation speed is likely to cause the material particles to not fully fall into the mixing unit), so as to ensure effective material storage and discharging. In addition, the rotation speeds of the discharge plates 5 can also be different, which can be set according to actual batching requirements, and the present application does not make specific limitations. Preferably, the discharge plate 5 can rotate at a constant speed. The volume of the discharged material can be controlled by the length of the rotation time of the discharge plate 5, that is, the discharge volume (volume) can be controlled according to the rotation time of the discharge plate, and different raw materials in each storage tank can be delivered to the mixing unit according to the set ratio.

[0049] Specifically, multiple storage holes 5-1 can be provided, such as Figure 4 shown, and the multiple storage holes 5-1 are evenly distributed circumferentially along the surface of the discharge plate 5. By providing multiple storage holes 5-1, the storage and discharging of materials can be carried out simultaneously, improving the efficiency. Further, the storage tank 3 is generally cylindrical, and the shapes of the feed plate 4 and the discharge plate 5 are adapted to the internal shape of the storage tank 3, which are circular plate-shaped. The circular plate-shaped discharge plate 5 rotates relative to the feed plate 4 around its center (i.e., the center of the circular plate).

[0050] Preferably, the discharge plate 5 is driven to rotate by a motor 5-2, and the output shaft of the motor 5-2 is connected to the center of the discharge plate 5, thereby driving the discharge plate 5 to rotate. Specifically, the motor 5-2 is located below the storage tank 3, and its output shaft passes through the bottom of the storage tank 3 and is connected to the discharge plate 5 inside the storage tank 3. The motor 5-2 can be installed on a mounting bracket (not shown in the figure). By controlling the rotation speed of the output shaft of each motor 5-2, the rotation speed of the discharge plate 5 can be adjusted, thereby controlling the discharge volume of the raw materials and achieving the purpose of batching.

[0051] More specifically, such as Figure 2 and Figure 5As shown in the figure, the quantitative feeding assembly further includes a partition plate 6. The partition plate 6 is located above the feeding plate 4 and is inclined. The partition plate 6 is fixed to the inner wall of the storage tank 3. At the lower end of the inclined partition plate 6, there is a feeding channel 6-1 communicating with the feeding hole 4-1. The feeding channel 6-1 can be composed of a feeding hole and a feeding pipe. The feeding hole is opened on the partition plate 6, and the feeding pipe is inserted between the feeding hole of the partition plate 6 and the feeding hole 4-1 of the feeding plate 4. Of course, the feeding pipe can also be fixed (such as welded) to the bottom of the partition plate 6 and is located directly below the feeding hole. At the same time, the feeding pipe communicates with the feeding hole and the feeding hole 4-1 of the feeding plate 4. By providing the partition plate 6 with a feeding channel 6-1 and being inclined, it can ensure that the raw materials in the storage tank 3 slide into the feeding hole 4-1, and at the same time, prevent the raw materials from accumulating on the feeding plate 4. Further, on one side of the upper part of the feeding channel 6-1 close to the inner wall of the storage tank 3, there is also a baffle plate 6-2. The baffle plate 6-2 can be adapted to the shape of the feeding hole, thereby further ensuring that the raw materials in the storage tank 3 enter the feeding hole 4-1 of the feeding plate 4 through the feeding channel 6-1.

[0052] Further, in order to ensure the stable rotation of the discharging plate 5, both the feeding plate 4 and the discharging plate 5 are made of bakelite. This can ensure that the resistance during the rotation of the discharging plate is minimized and the wear is reduced as much as possible. Since the discharging plate 5 is in direct contact with no gap (fitting) with the bottom of the storage tank 3, the pellets will not run out from the bottom of the storage hole 5-1 to the bottom of the storage tank 3.

[0053] As Figure 7 shown in the figure, the mixing unit 1 includes a mixing tank 1-1 and a mixing mechanism 1-2. The bottom of the mixing tank 1-1 is provided with a discharging port for discharging the uniformly mixed raw materials. The mixing mechanism 1-2 is used to mix various raw materials in the mixing tank 1-1 evenly. Specifically, the mixing mechanism 1-2 is a stirring mechanism, including a power component (such as a motor) and a stirring component (such as blades). The power component is connected to the stirring component to drive the stirring component to rotate, thereby making various raw materials stirred and mixed evenly. Further, the top of the mixing tank 1-1 is provided with a feeding port. The shape and size of the feeding port are the same as those of the discharging hole 3-1 at the bottom of the storage tank 3. In this way, the storage tank 3 can be directly placed on the mixing tank 1-1, and the discharging hole 3-1 and the feeding port are vertically aligned and communicated, so that the raw materials can smoothly enter the mixing tank 1-1 through the feeding port. Of course, as Figure 2 shown in the figure, a discharging pipe 3-2 can also be provided. The discharging pipe 3-2 is connected to the discharging hole 3-1 and the feeding port, and the raw materials are sent into the mixing tank 1-1 through the discharging pipe 3-2.

[0054] Furthermore, the automatic batching device further includes a material pumping unit 8 for pumping raw materials into the feeding unit 2. Preferably, the material pumping unit 8 uses a negative pressure suction machine to supplement the raw materials into the corresponding storage tank in a negative pressure suction manner to ensure the automatic material pumping of different storage tanks.

[0055] In addition, a material level detector 7 can be arranged in the storage tank 3. When the material level in the storage tank 3 is insufficient, the material level detector 7 sends a signal, and the material pumping unit pumps material into the storage tank 3. Similarly, a material level detector can also be arranged in the mixing tank 1-1. When the material level in the mixing tank 1-1 is insufficient, a signal is sent, and the discharge plate 5 starts to discharge material. Further, the automatic batching device can further include a controller. The controller is electrically connected to each material level detector. At the same time, the controller is also electrically connected to the material pumping unit 8, the motor 5-2, and the stirring mechanism. When the material level detector in the storage tank 3 detects that the material level in the storage tank 3 is insufficient, it sends a signal to the controller. The controller controls the material pumping unit 8 to pump material into the storage tank 3. When the material level detector in the mixing tank 1-1 detects that the material level in the mixing tank 1-1 is insufficient, it sends a signal to the controller. The controller controls the motor 5-2 to rotate, and starts to discharge material into the mixing unit 1. At the same time, the controller controls the stirring mechanism to stir and mix the raw materials, so as to realize the synchronous linkage of the material pumping unit 8, the material discharging unit 2, and the mixing unit 1.

[0056] The working process of the automatic batching device of the present application will be described below.

[0057] First, the raw materials to be mixed are respectively sucked into the corresponding storage tanks 3. The weight ratio of the raw materials is converted into the corresponding volume ratio, and the rotation speed of the discharge plate 5 is set. In the initial state, the material storage hole 5-1 of the discharge plate 5 can be located directly below the feed hole 4-1 of the feed plate 4 (as shown in (a) of Figure 8 to ensure that the raw materials in the storage tank 3 enter the material storage hole 5-1 through the feed hole 4-1 and fill the material storage hole 5-1;

[0058] Then, each discharge plate 5 rotates at a constant speed according to the set speed (as shown by the arrow in Figure 8 , rotating clockwise, and of course it can also rotate counterclockwise). When the material storage hole 5-1 filled with raw materials rotates to communicate with the discharge hole 3-1 (as shown in (b) of Figure 8 ), the raw materials in the material storage hole 5-1 are gradually sent into the mixing tank 1-1 through the discharge hole 3-1. At the same time, another material storage hole 5-1 communicates with the feed hole 4-1, and the raw materials in the storage tank 3 gradually enter this material storage hole 5-1 through the feed hole 4-1 and fill this material storage hole 5-1; when the next material storage hole 5-1 filled with raw materials rotates to communicate with the discharge hole 3-1, it discharges material again, and so on, until each raw material is supplied to the required amount;

[0059] Finally, the various raw materials in the mixing tank 1-1 are mixed evenly by the mixing mechanism 1-2, so as to realize the uniform mixing of the raw materials with the preset ratio. Of course, while the material discharging unit 2 discharges material, the mixing mechanism 1-2 can perform the stirring and mixing action synchronously. After uniform mixing, the mixed material can be pumped to the next link of the production line through the negative pressure pumping device for subsequent production.

[0060] Generally speaking, through the structural design of the quantitative feeding component, the present application can quantitatively transport each raw material into the mixing unit, realizing the mixing of different raw materials in a set ratio, without complicated operation and treatment. Compared with manual batching and feeding, the automation degree and batching efficiency are higher.
