Description

Technical Field

[0001] This utility model belongs to the field of rock wool production technology, and in particular relates to a pendulum speed adjustment device for rock wool production. Background Technology

[0002] Rock wool is made from high-quality basalt, dolomite and other raw materials. After being melted at a high temperature of over 1450℃, it is centrifuged into fibers using an internationally advanced four-axis centrifuge. At the same time, a certain amount of binder, dustproof oil and water-repellent agent are sprayed in. The fibers are then collected by a cotton collecting machine, and after being laid in a three-dimensional manner using a pendulum method, they are cured and cut to form rock wool products of different specifications and uses.

[0003] In the production process of rock wool, the pendulum device is a crucial piece of equipment. The reciprocating motion of the pendulum limits and folds the rock wool evenly, increasing its strength. However, the existing pendulum device cannot adjust the speed of the pendulum during the reciprocating motion. If a uniform speed is used at the turning position, a large amount of rock wool will accumulate at the turning position, resulting in waste of rock wool. Utility Model Content

[0004] In view of the defects or deficiencies in the existing technology, this utility model provides a pendulum speed adjustment device for rock wool production, which can adjust the speed of the pendulum during the reciprocating motion, thereby reducing the waste of rock wool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An embodiment of this utility model provides a pendulum speed adjustment device for rock wool production, including a pendulum, a connecting rod, and a pendulum motor. The pendulum motor is connected to the pendulum via the connecting rod, and a base disk is fixed to one end of the pendulum motor near the connecting rod. Multiple proximity switches are provided on the base disk.

[0007] Furthermore, the positions of multiple proximity switches are set according to the swing position of the pendulum.

[0008] Furthermore, the connecting rod includes a first connecting rod and a second connecting rod, with one end of the first connecting rod hinged to one end of the second connecting rod.

[0009] Furthermore, the end of the first connecting rod away from the second connecting rod is hinged to the middle of the pendulum.

[0010] Furthermore, the end of the second connecting rod away from the first connecting rod is fixedly connected to the output shaft of the pendulum motor.

[0011] Furthermore, the base disc is sleeved on the output shaft of the pendulum motor and fixed to the end face of the pendulum motor.

[0012] Furthermore, the proximity switch is located on the side of the base disk near the connecting rod.

[0013] Furthermore, a PLC controller and a frequency converter are also provided, with the PLC controller and the frequency converter being electrically connected.

[0014] Furthermore, the frequency converter is connected to the pendulum motor.

[0015] Furthermore, the proximity switch is electrically connected to the PLC controller.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a base disc with multiple proximity switches positioned according to the pendulum's swing position. As the connecting rod rotates, it approaches different proximity switches, thereby controlling the pendulum's speed during reciprocating motion. This allows the pendulum to quickly pass through turning positions, preventing rock wool from accumulating and being wasted. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the pendulum speed adjustment device in an embodiment of this utility model;

[0019] Figure 2 This is a schematic diagram of the base disc structure in an embodiment of the present invention;

[0020] The components include: 1. pendulum; 2. rotating shaft; 3. pendulum motor; 4. first connecting rod; 5. second connecting rod; 6. base disc; and 7. proximity switch. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] A typical embodiment of this utility model is as follows: Figure 1 As shown, a pendulum speed adjustment device for rock wool production includes a pendulum 1, the top of which is connected to a rotating shaft 2. The pendulum 1 can rotate around the rotating shaft 2 to achieve reciprocating swing. The pendulum 1 is connected to a pendulum motor 3 through a connecting rod, and the pendulum motor 3 drives the pendulum 1 to move through the connecting rod.

[0023] The connecting rod includes a first connecting rod 4 and a second connecting rod 5. One end of the first connecting rod 4 is hinged to one end of the second connecting rod 5. The end of the first connecting rod 4 away from the second connecting rod 5 is hinged to the middle of the pendulum 1. The end of the second connecting rod 5 away from the first connecting rod 4 is fixedly connected to the output shaft of the pendulum motor 3. The pendulum motor 3 drives the connecting rod to rotate, thereby driving the pendulum 1 to reciprocate.

[0024] It can be seen that when the first connecting rod 4 and the second connecting rod 5 are in a straight line, the pendulum 1 is in the first extreme position, and when the first connecting rod 4 and the second connecting rod 5 coincide, the pendulum 1 is in the second extreme position. The pendulum 1 swings back and forth between the first extreme position and the second extreme position.

[0025] like Figure 2 As shown, a base disk 6 is fitted onto the output shaft of the pendulum motor 3. The base disk 6 is fixed to the end face of the pendulum motor 3. Multiple proximity switches 7 are provided on the side of the base disk 6 near the connecting rod. The position of the proximity switches 7 is set according to the swing position of the pendulum 1. When the pendulum motor 3 drives the connecting rod to rotate, the second connecting rod 5 will pass through the proximity switches 7 on the base disk 6 once. The proximity switches 7 are electrically connected to the PLC controller. The PLC controller is also electrically connected to the frequency converter. The frequency converter is electrically connected to the pendulum motor 3. The PLC controller controls the speed of the pendulum motor 3 by adjusting the output frequency of the frequency converter, thereby controlling the speed of the pendulum 1.

[0026] In use, the cotton cloth area and turning area are allocated according to the pendulum's motion trajectory. The position of the connecting rod is determined by the different positions of the pendulum's motion. The proximity switch is fixed at different position points on the base disc of the proximity switch. The digital input signal of the proximity switch is transmitted to the PLC. The control frequency converter of the pendulum motor communicates with the PLC through 485 communication or TCP / IP communication to read and write the operating frequency of the frequency converter.

[0027] After the pendulum motor is turned on, the pendulum device starts to run. When the connecting rod approaches the first proximity switch, the PLC writes the first frequency to the frequency converter, and the frequency converter controls the speed of the pendulum motor to change. When it reaches the second proximity switch, the PLC writes the second frequency to the frequency converter, changing the speed of the pendulum motor. The proximity switches at the four positions are processed in the same way, and the PLC writes different frequencies to the frequency converter, thereby producing speed changes.

[0028] This invention features a base disc with multiple proximity switches positioned according to the pendulum's swing position. As the connecting rod rotates, it approaches different proximity switches, thereby controlling the pendulum's speed during reciprocating motion. This allows the pendulum to quickly pass through turning positions, preventing rock wool from accumulating and being wasted.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
