Description

Technical Field

[0001] The utility model relates to the technical field of adding devices, in particular to a gypsum board glass fiber adding device. Background Art

[0002] In the production process of gypsum board, in order to enhance its own strength, it is generally necessary to add auxiliary material glass fiber. However, the fluidity of glass fiber material is extremely poor and it is easy to get blocked when feeding in the silo.

[0003] In order to avoid silo blockage, a vibrator is usually installed on the side wall of the silo to increase the fluidity of the glass fiber. Since this method uses conventional single-stage vibration, it only has the effect of vibration and cannot grasp the discharge limit of the silo port in real time;

[0004] Since the materials in the silo are in a state of continuous accumulation, once the accumulation of materials exceeds the maximum limit of the silo discharge port, even if the silo port is in a vibrating state, it is easy to cause material blockage.

[0005] In summary, the existing devices still use single-stage vibration at the silo outlet, and the discharge limit cannot be monitored in real time at the silo outlet. Once the accumulation of materials exceeds the maximum limit of the silo discharge port, even if the silo port is in a vibrating state, it is easy to cause technical problems such as material blockage.

[0011] The laser level switch is used to detect the height data of the material in the pre-feeding hopper in real time;

[0012] When the laser level switch detects abnormal material height, it controls the first-level vibrator to start or stop, so as to stop the first-level vibrator when the material height data exceeds the upper limit of the target fluctuation range, and start the first-level vibrator when it exceeds the lower limit of the target fluctuation range.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-2 As shown, a gypsum board glass fiber adding device includes a silo 1, a first-stage vibrator 2, a pre-feeding hopper 3, a laser level switch 4 and a second-stage vibrator 5;

[0027] The first-stage vibrator 2 is installed below the silo 1, and the second-stage vibrator 5 is installed below the first-stage vibrator 2 on a side away from the silo 1;

[0028] The pre-feeding hopper 3 is mounted on the side of the second-stage vibrator 5 close to the first-stage vibrator 2 through a bracket. The pre-feeding hopper 3 can vibrate synchronously with the second-stage vibrator 5, that is, the end surface of the material in the pre-feeding hopper 3 is kept flat by vibration, thereby ensuring the accuracy of the height data monitored by the laser level switch;

[0029] A laser material level switch 4 is installed on the pre-feeding hopper 3, and the laser material level switch 4 is communicatively connected with the first-stage vibrator 2;

[0030] The laser material level switch 4 is used to detect the height data of the material in the pre-feeding hopper 3 in real time;

[0031] When the laser level switch 4 detects abnormal material height, it controls the first-stage vibrator 2 to start or stop, so as to stop the first-stage vibrator 2 when the material height data exceeds the upper limit of the target fluctuation range, and start the first-stage vibrator 2 when it exceeds the lower limit of the target fluctuation range.

[0032] The device adopts an intelligent two-stage vibration adding method to disperse the material in the silo through two-stage vibration, which effectively increases the fluidity of the material.

[0033] At the same time, the pre-feeding hopper can timely adjust its own storage volume according to the maximum flow rate of its own discharge port, so that the storage volume is always kept within the safe range of free material conduction at the discharge port of the pre-feeding hopper, thereby effectively avoiding the possibility of blockage of materials during transportation.

[0034] The material in the pre-feed hopper 3 generally cannot be piled up too high. Excessive material accumulation can easily cause blockage of the opening at the lower end of the pre-feed hopper 3, thereby affecting the discharge of the material. Therefore, it is necessary to work under the detection of the laser level switch 4, that is, the laser level switch 4 is a conventional laser level meter for monitoring the material level.

[0035] Specifically, the distance between the first-stage vibrator 2 and the discharge port of the silo 1 is 5-8 cm. The gap between the two is conducive to the falling of the material in the silo 1, and also provides a certain range of movement for the first-stage vibrator 2.

[0036] Since the material transported by the second-stage vibrator 5 mainly comes from the pre-feeding hopper 3, and the pre-feeding hopper 3 mainly stores the material introduced by the first-stage vibrator 2, the pre-feeding hopper 3 needs to be able to store enough material for the second-stage vibrator 5 to transport, that is, the material transported by the first-stage vibrator 2 needs to be greater than the material transported by the second-stage vibrator 5.

[0037] Specifically, Figure 1-2 As shown, the exciting force of the first-stage vibrator 2 is greater than the exciting force of the second-stage vibrator 5 .

[0038] Since the material stored in the pre-feeding hopper 3 needs to be further transported to the second-stage vibrator 5 , the shape of the pre-feeding hopper 3 is designed in order to increase the fluidity of the material and also to cooperate with the operation of the laser level switch.

[0039] Specifically, Figure 1-2 As shown, the pre-feeding hopper 3 is arranged as a funnel-shaped structure, with the wide end of the pre-feeding hopper 3 facing the first-stage vibrator 2, and the narrow end of the pre-feeding hopper 3 facing the second-stage vibrator 5. The structure of being wide at the top and narrow at the bottom is conducive to the accumulation of materials at the bottom of the pre-feeding hopper 3, that is, it is conducive to the concentration of materials. The concentrated materials are in.

[0040] After the pre-feeding hopper 3 is introduced into the second-stage vibrator 5, the second-stage vibrator 5 will introduce the material into the gypsum board production line. The amount of glass fiber required on the gypsum board production line is generally changing, so the single introduction amount of the second-stage vibrator 5 also needs to be constantly changed.

[0041] Specifically, Figure 1-2 As shown, the first-stage vibrator 2 and the second-stage vibrator 5 are both electromagnetic vibrating feeders, the vibration frequency of the first-stage vibrator 2 is a constant frequency, and the vibration frequency of the second-stage vibrator 5 is a variable frequency, wherein the first-stage vibrator 2 uniformly transports the glass fiber from the silo 1 to the pre-feeding hopper 3 of the second-stage vibrator 5, and the second-stage vibrator can be controlled to match the main line speed according to the preset value to achieve follow-up changes, wherein the main line speed is the speed of the feeding amount of glass fiber required in the subsequent process.

[0042] Working principle:

[0043] When feeding glass fiber, the first-stage vibrator 2 and the second-stage vibrator 5 are turned on synchronously, the hatch in the silo 1 is opened, and the material falls into the first-stage vibrator 2. With the vibration of the first-stage vibrator 2, the material gradually enters the pre-feeding hopper 3, and then enters the second-stage vibrator 5 from the pre-feeding hopper 3. During the conveying process, when the laser level switch 4 detects an abnormal material height, that is, when the detected height value exceeds the upper limit of the target fluctuation range, the first-stage vibrator 2 is stopped. At this time, the second-stage vibrator 5 maintains the trend of movement and feeds the material until the material height value monitored by the laser level switch 4 exceeds the lower limit of the target fluctuation range. At this time, the first-stage vibrator 2 is started to continue feeding, and this cycle is repeated, wherein the material height data is the stacking height of the material in the pre-feeding hopper 3.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
