Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption roller technology, and more specifically, to a vacuum control device for a vacuum adsorption roller. Background Technology

[0002] Vacuum adsorption rollers, as an important industrial piece of equipment, are widely used in the processing and transport of materials such as films, paper, and metals. Their main function is to firmly adsorb materials onto the roller surface by generating negative pressure, thereby achieving smooth conveying and processing. An effective control system can not only improve production efficiency but also ensure product quality.

[0003] When the material passing through the vacuum adsorption roller is sticky or the screen mesh is too dense, there is a certain probability that the screen mesh will become clogged. When the screen mesh becomes clogged, the vacuum value will increase at a constant vacuum pump frequency, leading to an increase in the vacuum pump current. This can cause the frequency converter to alarm and shut down, or the vacuum pump to burn out, resulting in production downtime and wasted resources. Therefore, to solve the above problems, we propose a vacuum control device for the vacuum adsorption roller. Utility Model Content

[0004] To solve the above problems, this utility model provides a vacuum control device for a vacuum adsorption roller, which adopts the following technical solution:

[0005] A vacuum control device for a vacuum adsorption roller includes a drive shaft, an adsorption roller sleeved on the side wall of the drive shaft, a drive motor connected to one end of the drive shaft, a vacuum pump on one side of the adsorption roller, a three-way valve and a sensor between the vacuum pump and the adsorption roller, and the adsorption roller, the three-way valve, the sensor and the vacuum pump are all connected by connecting pipes, and a controller is connected to the top of the three-way valve.

[0006] The adsorption roller has multiple sets of through holes arranged in a linear array on its sidewall, and the through holes in the same set are arranged in a ring array on the sidewall of the adsorption roller.

[0007] By adopting the above technical solution, when using this equipment, the operator places the membrane on the side wall of the adsorption roller, and then the vacuum pump is turned on to create a negative pressure on the side wall of the adsorption roller, thereby adsorbing the membrane. Then, the drive motor drives the transmission shaft to rotate, and the transmission shaft drives the adsorption roller to move, thus conveying the membrane.

[0008] A three-way valve is added to the equipment to regulate the working status of the vacuum pump and control the negative pressure. A sensor monitors the vacuum level in real time. The controller adjusts the operation of the vacuum pump and the three-way valve based on the information from the sensor to maintain a stable adsorption state. When the through holes on the surface of the adsorption roller become blocked, the three-way valve is dynamically adjusted to allow some clean air to be added to the adsorption roller, ensuring that the vacuum value of the adsorption roller is within a reasonable range. This ensures the operation of the equipment and prevents downtime due to malfunctions. At the same time, the status of the three-way valve is displayed on the human-machine interface control panel to remind the operator that the adsorption roller is blocked and should not be dealt with temporarily, ensuring smooth production for one production cycle. After one production cycle, thorough cleaning and maintenance are carried out to maintain the processing efficiency of the equipment and help avoid the possibility of equipment damage.

[0009] Furthermore, support columns are provided on both sides of the drive shaft, and both support columns are located below the drive shaft.

[0010] By adopting the above technical solution, the two support columns can support and stabilize the membrane, which helps to maintain the stability of membrane delivery.

[0011] Furthermore, a frequency converter is installed on the side wall of the vacuum pump.

[0012] By adopting the above technical solution, the vacuum pump sidewall can be equipped with a frequency converter to adjust the vacuum pump frequency and achieve a vacuum level that adapts to the working conditions.

[0013] Furthermore, a human-machine interface control panel is provided on one side of the adsorption roller, and the human-machine interface control panel is linearly connected to the drive motor, three-way valve, sensor and vacuum pump.

[0014] By adopting the above technical solution and setting the human-machine interface control panel, an interactive interface between the operator and the system is provided, which facilitates monitoring and adjustment.

[0015] Furthermore, both ends of the three-way valve are provided with assembly pipes, and the connecting pipe adjacent to the three-way valve is sleeved on the side wall of the assembly pipe on the same side. The assembly pipe and the connecting pipe on the same side are fixed together by a flange.

[0016] By adopting the above technical solution, the three-way valve is equipped with assembly pipes at both ends. The workers will put the connecting pipe on the side wall of the assembly pipe and then fix it with flanges and fasteners in the existing technology. The insertion of the connecting pipe and the assembly pipe helps to maintain the stability of the three-way valve assembly.

[0017] Furthermore, clamps are fitted onto both flange sidewalls on the same side, and the clamps are fixed by bolts and nuts.

[0018] By adopting the above technical solution, after the three-way valve is installed, it is fitted with clamps on the sidewalls of the two flanges on the same side, and then fixed with bolts and nuts. This can protect the flanges and tighten the two flanges, which helps to maintain the precision of the three-way valve installation.

[0019] In summary, this utility model has the following beneficial technical effects:

[0020] (1) In this utility model, a three-way valve is added to the equipment. When the through hole of the adsorption roller is blocked, the three-way valve is dynamically adjusted to allow the adsorption roller to replenish some clean air, ensuring that the vacuum value of the adsorption roller is within a reasonable range. This ensures the operation of the equipment and prevents it from malfunctioning and shutting down. At the same time, the status of the three-way valve is sent to the human-machine interface control panel to remind the operator that the adsorption roller is blocked and should not be dealt with temporarily, ensuring smooth production for one production cycle. After one production cycle, the key cleaning and maintenance are carried out, which helps to maintain the processing efficiency of the equipment and helps to avoid the possibility of equipment damage.

[0029] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0030] Please see Figure 1-3 A vacuum control device for a vacuum adsorption roller includes a drive shaft 2, an adsorption roller 1 sleeved on the side wall of the drive shaft 2, a drive motor 8 connected to one end of the drive shaft 2, a vacuum pump 6 on one side of the adsorption roller 1, a three-way valve 4 and a sensor 5 between the vacuum pump 6 and the adsorption roller 1, and the adsorption roller 1, the three-way valve 4, the sensor 5 and the vacuum pump 6 are all connected by a connecting pipe 10, and a controller 3 is connected to the top of the three-way valve 4; the side wall of the adsorption roller 1 has multiple sets of through holes arranged in a linear array, and the through holes in the same set are arranged in a ring array on the side wall of the adsorption roller 1; a human-machine interface control panel 7 is provided on one side of the adsorption roller 1, and the human-machine interface control panel 7 is linearly connected to the drive motor 8, the three-way valve 4, the sensor 5 and the vacuum pump 6.

[0031] When using the equipment, the operator places the membrane on the side wall of the adsorption roller 1, and then the vacuum pump 6 is turned on to create a negative pressure on the side wall of the adsorption roller 1, which in turn adsorbs the membrane. Then, the drive motor 8 drives the transmission shaft 2 to rotate, and the transmission shaft 2 drives the adsorption roller 1 to transport the membrane.

[0032] A three-way valve 4 is added to the equipment to regulate the working state of the vacuum pump 6 and control the magnitude of the negative pressure. The sensor 5 monitors the vacuum level in real time. The controller 3 adjusts the operation of the vacuum pump 6 and the three-way valve 4 based on the information fed back by the sensor 5 to maintain a stable adsorption state. When the through holes on the surface of the adsorption roller 1 become blocked, the three-way valve 4 is dynamically adjusted to allow the adsorption roller 1 to be supplemented with some clean air, ensuring that the vacuum value of the adsorption roller 1 is within a reasonable range. This ensures the operation of the equipment and prevents malfunctions and shutdowns. At the same time, the status of the three-way valve 4 is sent to the human-machine interface control panel 7 to remind the operator that the adsorption roller 1 is blocked and should not be dealt with temporarily to ensure smooth production for one production cycle. After one production cycle, thorough cleaning and maintenance are carried out to maintain the processing efficiency of the equipment and help avoid the possibility of equipment damage.

[0033] Support columns 9 are provided on both sides of the drive shaft 2. Both support columns 9 are located below the drive shaft 2. The two support columns 9 serve to support and stabilize the membrane, which helps to maintain the stability of membrane delivery.

[0034] The vacuum pump 6 is equipped with a frequency converter on its side wall. The frequency converter can be used to adjust the frequency of the vacuum pump 6 to achieve a vacuum level that is suitable for the working conditions.

[0035] Both ends of the three-way valve 4 are provided with assembly pipes 12. The connecting pipe 10 adjacent to the three-way valve 4 is sleeved on the side wall of the assembly pipe 12 on the same side. The assembly pipe 12 and the connecting pipe 10 on the same side are fixed by flanges. Both flange side walls on the same side are provided with clamps 11, and the clamps 11 are fixed by bolts and nuts.

[0036] The three-way valve 4 has assembly pipes 12 at both ends. The operator puts the connecting pipe 10 on the side wall of the assembly pipe 12 and then fixes it with flanges and existing fasteners. The insertion of the connecting pipe 10 and the assembly pipe 12 helps to maintain the stability of the assembly of the three-way valve 4. After the three-way valve 4 is installed, the clamp 11 is put on the side wall of the two flanges on the same side and then fixed with bolts and nuts. This can protect the flanges and tighten the two flanges, which helps to maintain the precision of the installation of the three-way valve 4.

[0037] The implementation principle of this utility model embodiment is as follows: When the equipment is used, the operator places the membrane on the side wall of the adsorption roller 1, and then the vacuum pump 6 is turned to generate negative pressure on the side wall of the adsorption roller 1, thereby adsorbing the membrane. Then, the drive motor 8 drives the transmission shaft 2 to rotate, and the transmission shaft 2 drives the adsorption roller 1 to drive, thus conveying the membrane.

[0038] A three-way valve 4 is added to the equipment to regulate the working state of the vacuum pump 6 and control the magnitude of the negative pressure. The sensor 5 monitors the vacuum level in real time. The controller 3 adjusts the operation of the vacuum pump 6 and the three-way valve 4 based on the information fed back by the sensor 5 to maintain a stable adsorption state. When the through holes on the surface of the adsorption roller 1 become blocked, the three-way valve 4 is dynamically adjusted to allow the adsorption roller 1 to be supplemented with some clean air, ensuring that the vacuum value of the adsorption roller 1 is within a reasonable range. This ensures the operation of the equipment and prevents malfunctions and shutdowns. At the same time, the status of the three-way valve 4 is sent to the human-machine interface control panel 7 to remind the operator that the adsorption roller 1 is blocked and should not be dealt with temporarily to ensure smooth production for one production cycle. After one production cycle, thorough cleaning and maintenance are carried out to maintain the processing efficiency of the equipment and help avoid the possibility of equipment damage.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
