Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-5 A film production material silo with alarm function includes a silo body 1, with a discharge port 2 at the bottom of the silo body 1. The silo body 1 is used to store raw materials, and the discharge port 2 is used to discharge the raw materials for film production. Multiple support rollers 3 are fixedly installed through the bottom of the silo body 1. The multiple support rollers 3 are distributed in a circular array, which makes the support rollers 3 evenly distributed and does not disrupt the center of gravity of the silo body 1. The bottom of the support rollers 3 is fixedly connected to the ground, making the support rollers 3 and the silo body 1 more stable during operation.
[0018] Please see Figure 5 An overload alarm mechanism 5 is installed near the top of the support roller 3 to monitor and alarm when raw materials are added, preventing overflow. The overload alarm mechanism 5 includes an electromagnet 51, which is fixedly installed near the top of the support roller 3. An armature 52 is slidably mounted on the support roller 3. The magnetic force of the electromagnet 51 is changed by adjusting the current intensity, thereby changing the position of the armature 52. It is important to note that a stop is provided on the support roller 3 to control the maximum falling distance of the armature 52, preventing the armature 52 from losing its magnetic connection with the electromagnet 51. A pressing plate 53 is fixedly installed between multiple armatures 52 to increase the contact area with the raw materials, facilitating the pressing of the pressing plate 53 by the raw materials, thereby causing the pressing plate 53 to move upwards, and consequently, the armatures 52 to move. A cable routing ring 54 is fixedly installed on the surface of the chamber 1. The cable routing ring 54 is fixedly connected to the support roller 3. The cable routing ring 54 is used to route and separate the wires of multiple electromagnets 51 to avoid interference or wire tangling.
[0019] It should be noted that the electromagnet 51 is connected to an alarm. The alarm is activated by converting the disturbance of the magnetic force of the electromagnet 51 by the displacement of the armature 52 into an electrical signal. That is, when the armature 52 is displaced, the armature 52 moves closer to the electromagnet 51, which causes a change in the magnetic field of the electromagnet 51. This change will trigger the alarm.
[0020] Example 1: In this embodiment, a residual material alarm mechanism 4 is provided between the support roller 3 and the bin 1 to monitor and alarm the residual material in the bin 1, and the amount of residual material can be adjusted to improve the applicability of the device.
[0021] Please see Figures 2-4 The remaining quantity alarm mechanism 4 includes a contact sensor 41, which is fixedly mounted on the support roller 3. The contact sensor 41 is electrically connected to a buzzer alarm. Through the electrical connection between the contact sensor 41 and the buzzer alarm, the contact sensor 41 can control the audible and visual alarm of the buzzer alarm. Furthermore, the electrical connection lines are discharged through the inside of the support roller 3, which has the effect of moisture and dust prevention.
[0022] In this embodiment, a contact ball 42 is slidably mounted on the support roller 3 below the contact sensor 41. When the contact ball 42 contacts the contact sensor 41, the circuit is connected, and the buzzer alarm sounds. When the contact ball 42 is removed from the contact sensor 41, the circuit is disconnected, and the buzzer alarm stops working. The buzzer alarm can be controlled by controlling the position of the contact ball 42.
[0023] Please see Figure 3 and Figure 4 A connecting rod 43 is fixedly installed at the bottom of the contact ball 42. The connecting rod 43 is slidably connected to the support roller 3, so that the connecting rod 43 does not affect the vertical movement of the contact ball 42 along the support roller 3. A piston 44 is fixedly connected to the bottom of the connecting rod 43. A movable seat 45 is fixedly installed on the chamber 1. The piston 44 is slidably connected to the support roller 3, so that the vertical movement of the piston 44 is not affected by the support roller 3. The piston 44 and the movable seat 45 are adapted to each other, that is, the piston 44 contacts the inner wall of the movable seat 45, so that the displacement of the piston 44 can be controlled by the air pressure control in the movable seat 45.
[0024] In detail, when the movable seat 45 is under negative pressure, the contact ball 42 moves downward along the support roller 3 and away from the contact sensor 41 under the negative pressure of the movable seat 45 and the gravity of the contact ball 42. By controlling the pressure of the negative pressure, the distance between the contact ball 42 and the contact sensor 41 can be controlled, thereby controlling the alarm range of the remaining material. When the movable seat 45 is under positive pressure, the positive pressure of the movable seat 45 will squeeze the piston 44, causing the piston 44 to have an upward tendency. When the material leaves the contact ball 42, under the action of the positive pressure of the movable seat 45, the piston 44 moves upward, thereby driving the contact ball 42 to move upward and contact the contact sensor 41 to generate an alarm.
[0025] It should be noted that the top of the movable seat 45 and the chamber 1 are connected through micropores, which prevents raw materials from entering the interior of the movable seat 45 while the top of the movable seat 45 does not affect the displacement of the piston 44.
[0026] In this embodiment, a gas equalization ring 46 is fixedly connected to the bottom end of the movable seat 45. The gas equalization ring 46 is connected to the movable seat 45. The gas equalization ring 46 can uniformly adjust the air pressure of the movable seats 45 on multiple support rollers 3, avoiding uneven air pressure in multiple movable seats 45, which would cause uneven height of the contact ball 42 and affect the monitoring accuracy. In addition, an air inlet pipe 47 is fixedly connected to the gas equalization ring 46, and an air extraction pipe 48 is also connected to the gas equalization ring 46. The air inlet pipe 47 is used to fill the gas equalization ring 46 with gas, thereby filling the gas equalization ring 46 with positive pressure. The air extraction pipe 48 is used to extract the gas from the gas equalization ring 46, thereby making the gas equalization ring 46 with negative pressure, thereby adjusting the position of the piston 44. It should be noted that valves are provided on both the air inlet pipe 47 and the air extraction pipe 48, and air pumps are connected to both the air inlet pipe 47 and the air extraction pipe 48.
[0027] It should be noted that controlling the position and upward force of the contact ball 42 by means of air pressure is more accurate and stable, easy to adjust and unaffected by dust and gas medium inside the chamber 1.
[0028] A film production material silo with alarm function, the working principle of which is as follows: Adjustment: When the air pump is working, air is drawn from the equalizing ring 46 through the air extraction pipe 48, creating a negative pressure inside the equalizing ring 46. The equalizing ring 46 is connected to the movable seat 45, creating a negative pressure inside the movable seat 45. Under the action of the negative pressure, the piston 44 moves downward along the movable seat 45. The downward movement of the piston 44 drives the contact ball 42 downward through the connecting rod 43. By controlling the magnitude of the negative pressure, the downward movement distance of the piston 44 can be controlled, thereby controlling the position of the contact ball 42. When the electromagnet 51 is working, the position of the armature 52 can be controlled by controlling the magnetic force of the electromagnet 51.
[0029] Sample loading: By directly filling the chamber 1 with raw material, due to the negative pressure of the equalizing ring 46 and the spherical surface of the contact ball 42, the raw material will not force the position of the contact ball 42 to change, and the raw material will submerge the contact ball 42, thereby forcing the contact ball 42 to be fixed. When the raw material is gradually added to the point of contact with the extrusion plate 53, the continued addition of raw material will force the extrusion plate 53 to move upward or shake, thereby driving the armature 52 to move along the support roller 3, which in turn disturbs the magnetic field of the electromagnet 51, causing the alarm to sound and reminding that the sample loading is over.
[0030] Balance alarm: After the sample loading is completed, the air pump is started, and gas is injected into the gas equalization ring 46 through the air inlet pipe 47, so that the gas equalization ring 46 is filled with positive pressure, thereby the movable seat 45 is in a positive pressure state. The positive pressure of the movable seat 45 will squeeze the piston 44, so that the piston 44 has an upward movement tendency. When the material is discharged for film production, the raw material is gradually discharged along the discharge port 2 until the squeezing and fixing effect of the raw material on the contact ball 42 is less than the upward movement tendency of the contact ball 42. The contact ball 42 moves upward and contacts the contact sensor 41, thereby triggering the buzzer alarm to remind that the balance is insufficient.
[0031] Special Alarm: There are multiple residual alarm mechanisms 4 arranged in a circular array. When not all residual alarm mechanisms 4 alarm, it indicates that the raw material is blocking the contact balls 42 in the un-alarmed portion. By pressurizing the gas equalization ring 46, if all alarms are triggered normally without fluctuation after pressurization, it indicates a simple blockage in a single component, indicating insufficient raw material. If the buzzer alarm fluctuates, stops, or remains unchanged after pressurization, it indicates that the raw material is bridging or clumping, requiring intervention. This effectively reduces the false alarm rate of residual material alarms.
[0032] Example 2: The difference between this embodiment and embodiment one is that the equalizing ring 46 is replaced with an electromagnet 51 and the piston 44 is replaced with an armature 52. The position of the armature 52 is controlled by changing the magnetic force of the electromagnet 51. Compared with embodiment one, the control principle of the residual alarm mechanism 4 and the over-alarm mechanism 5 is the same, avoiding the use of a pump. Moreover, it can share a set of PLC control programs with the over-alarm mechanism 5, reducing the complexity and cost of the overall device.
