Abstract
Description
Technical Field
[0001] The present application relates to the field of papermaking technology, and in particular to a clamping device and a cutting device. Background Art
[0002] During the paper tube cutting process, the paper tube must first be gripped with a clamping jaw before being cut. Due to varying tube thicknesses, the clamping jaws often require manual adjustment to achieve varying grip depths. However, when the device is powered on, the jaws are extended and rotate rapidly, making adjustment of the clamping jaws dangerous and potentially harmful. When the device is powered off, the jaws retract, making adjustment impossible, and increasing operational complexity. Furthermore, this process can easily lead to accidental device startup, posing a safety hazard. Utility Model Content
[0003] In view of the above problems, the present application is proposed. The present application provides a clamping device and a cutting device.
[0004] According to one aspect of the present application, there is provided a clamping device, comprising:
[0005] Pneumatic clamping part and gas transmission part; the gas transmission part includes multiple gas transmission pipes, the pneumatic clamping part has an air inlet and an air outlet, the air inlet end of the gas transmission pipe is connected to the air outlet of the pneumatic clamping part, and the air outlet end of the gas transmission pipe is connected to the air inlet of the pneumatic clamping part, the pneumatic clamping part includes a retractable clamping jaw, and the gas transmission pipe provides power to the retractable clamping jaw through a gas source.
[0006] Compared with the prior art, the clamping device provided in the present application includes a pneumatic clamping part and a gas transmission part, wherein the gas transmission part includes a plurality of gas transmission pipes, and the pneumatic clamping part has an air inlet and an air outlet, wherein the air inlet end of the gas transmission pipe is connected to the air outlet of the pneumatic clamping part, and the air outlet end of the gas transmission pipe is connected to the air inlet of the pneumatic clamping part, and the pneumatic clamping part includes a retractable clamping claw, and the gas transmission pipe provides power to the retractable clamping claw through an air source. Based on this, the air source can enter the air outlet of the pneumatic clamping part through the air inlet end of the gas transmission pipe to reversely supply air to the pneumatic clamping part, so that the retractable clamping claw is in a working state (for example, an extended state). At this time, the components of the retractable clamping claw (for example, a screw) can be adjusted, reducing the difficulty of operation. Thereafter, if the retractable clamping claw needs to be adjusted to a retracted state, the gas to be discharged can be discharged from the air inlet of the pneumatic clamping part through the air outlet end of the gas transmission pipe. Furthermore, the present invention does not require power on during the adjustment process, which not only reduces energy consumption but also prevents the device from being accidentally started, thus reducing safety hazards. Furthermore, the present invention can also control the degree of extension and retraction of the retractable jaws by controlling the flow of gas entering the pneumatic clamping portion, further reducing operational difficulty.
[0007] According to another aspect of the present application, a cutting device is provided, comprising the above-mentioned clamping device.
[0008] Compared with the prior art, the beneficial effects of the cutting equipment provided in this application are the same as those of the above-mentioned clamping device, which will not be described in detail here.

DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solutions and advantages of this application more apparent, the following exemplary embodiments of this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, rather than all the embodiments of this application, and it should be understood that this application is not limited to the exemplary embodiments described herein.
[0015] When the paper tube cutting machine is powered on, the jaws extend and rotate rapidly, making it easy for the operator to adjust the jaw screws, which can cause mechanical injuries. When the machine is powered off, the jaws retract, making it impossible to adjust the jaw screws, increasing operational complexity. Furthermore, this process can easily lead to the machine starting up accidentally, increasing safety risks.
[0016] In response to the above problems, the present application provides a clamping device that can adjust the components of the clamp without turning on the power, thereby reducing the operating difficulty and production energy consumption, and reducing safety hazards. Figure 1 FIG. 1 shows a schematic structural diagram of the clamping device according to an embodiment of the present application. Figure 1 As shown, the clamping device includes a pneumatic clamping part 1 and a gas transmission part 2; the gas transmission part 2 includes multiple gas transmission pipes 201, the pneumatic clamping part 1 has an air inlet 101 and an air outlet 102, the air inlet end of the gas transmission pipe 201 is connected to the air outlet 102 of the pneumatic clamping part 1, and the air outlet end of the gas transmission pipe 201 is connected to the air inlet 101 of the pneumatic clamping part 1, the pneumatic clamping part 1 includes a retractable clamping jaw 103, and the gas transmission pipe 201 provides power to the retractable clamping jaw 103 through a gas source.
[0017] During specific implementation, the gas source is passed into the air outlet 102 of the pneumatic clamping part 1 along the air inlet end of the gas transmission pipe 201 to reversely supply air to the pneumatic clamping part 1, so that the retractable clamping jaw 103 extends. At this time, the screw of the retractable clamping jaw 103 can be adjusted to achieve different clamping depths, thereby reducing the difficulty of operation. As the air flow in the pneumatic clamping part 1 increases, the retractable clamping jaw 103 can extend the length of the clamping jaw within the extendable length range, so that the operator can adjust its screw, further reducing the difficulty of operation. After the adjustment is completed, if it is necessary to adjust the retractable clamping jaw 103 to a retracted state, the gas to be discharged can be discharged from the air inlet 101 of the pneumatic clamping part 1 through the air outlet end of the gas transmission pipe 201.
[0018] During the process of adjusting the screw of the retractable clamping jaw 103, the operator does not need to turn on the power supply, which not only reduces energy consumption but also prevents the equipment from being accidentally started, thereby reducing safety hazards. In addition, the present application can also achieve the purpose of controlling the extension and retraction of the retractable clamping jaw 103 by controlling the flow rate of gas entering the pneumatic clamping part 1, further reducing the difficulty of operation.
[0019] It is understood that before reverse air supply is performed on the pneumatic clamping unit 1, the power to the pneumatic clamping unit 1 should be turned off and the air inside the pneumatic clamping unit 1 should be exhausted. If there is an initial air pressure inside the pneumatic clamping unit 1 when reverse air supply is performed on the pneumatic clamping unit 1, as the air flow into the air outlet 102 of the pneumatic clamping unit 1 increases, a small amount of air near the air outlet 102 may be exhausted due to the pressure difference, thereby affecting the operating results (for example, the extension degree of the retractable clamping jaw 103).
[0020] In an alternative approach, such as Figure 1As shown, the gas transmission unit 2 in the present application also includes a pressure regulating unit 202 provided on the gas transmission pipeline 201. The pressure regulating unit 202 includes a first switch 2021 and a second switch 2022. The gas source is connected to the inlet of the first switch 2021, the outlet of the first switch 2021 is connected to the gas inlet 101 of the pneumatic clamping unit 1, and the inlet of the second switch 2022 is connected to the gas outlet 102 of the pneumatic clamping unit 1. When the pneumatic clamping unit 1 is powered on, the first switch 2021 and the second switch 2022 are in a conducting state. At this time, the gas source can flow into the gas inlet 101 of the pneumatic clamping unit 1 along the outlet of the first switch 2021, and the gas to be discharged in the pneumatic clamping unit 1 can be discharged from the gas outlet 102 of the pneumatic clamping unit 1 through the inlet of the second switch 2022. With the cooperation of the above components, the retractable clamping jaw 103 can be extended and retracted.
[0021] For example, Figure 1 As shown, the pressure regulating part 202 in the present application also includes a third switch 2023 and a fourth switch 2024, and the third switch 2023 is connected in parallel with the fourth switch 2024; the air outlet 102 of the pneumatic clamping part 1 is respectively connected to the inlet of the second switch 2022 and the outlet of the third switch 2023, and the inlet of the third switch 2023 is arranged between the air source and the inlet of the first switch 2021; the inlet of the fourth switch 2024 and the outlet of the first switch 2021 are respectively connected to the air inlet 101 of the pneumatic clamping part 1, and the outlet of the fourth switch 2024 is connected to the outlet of the second switch 2022.
[0022] In actual application, when the pneumatic clamping part 1 is powered on, the first switch 2021 and the second switch 2022 are in the on state, and the third switch 2023 and the fourth switch 2024 are in the off state. When the pneumatic clamping part 1 is powered off, the first switch 2021 and the second switch 2022 are in the off state, and the third switch 2023 and the fourth switch 2024 are in the on state. At this time, the air source can be passed through the inlet of the third switch 2023 into the air outlet 102 of the pneumatic clamping part 1, reversely supplying air to the pneumatic clamping part 1, thereby providing power for the extension and retraction of the retractable clamping jaws 103. If exhaust is required, the gas to be exhausted can be passed from the air inlet 101 of the pneumatic clamping part 1 into the fourth switch 2024 and discharged from the gas transmission pipeline 201.
[0023] In an alternative approach, such as Figure 1As shown, the pneumatic clamping unit 1 of the present application further includes a housing 104 and a pneumatic drive mechanism 105. The housing 104 has a through hole for the retractable clamping jaw 103 to move. The retractable clamping jaw 103 is connected to the pneumatic drive mechanism 105, and a gas transmission pipeline 201 is in communication with the pneumatic cavity of the pneumatic drive mechanism 105. Therefore, when a gas source is passed through the gas transmission pipeline 201 into the pneumatic cavity of the pneumatic drive mechanism 105, the gas propels the retractable clamping jaw 103 to move within the housing 104, thereby enabling adjustment of the components of the retractable clamping jaw 103 and reducing operational difficulty.
[0024] For example, Figure 1 As shown, the pneumatic drive mechanism 105 in the present application includes a cylinder 1051 and a piston 1052 disposed within the cylinder 1051, wherein the piston rod 1053 of the piston 1052 is connected to the retractable clamping jaw 103. In other words, when reverse inflation is performed in the cylinder 1051, the piston rod 1053 can be pushed by the gas to move toward the retractable clamping jaw 103, thereby driving the retractable clamping jaw 103 to extend from the housing 104. At this time, the screws of the retractable clamping jaw 103 can be adjusted to achieve different clamping depths, thereby reducing the difficulty of operation. As the airflow in the cylinder 1051 increases, the retractable clamping jaw 103 can extend the length of the clamping jaw within the extendable length range, so that the operator can adjust its screws, further reducing the difficulty of operation.
[0025] For example, Figure 1 As shown, the air inlet 101 of the pneumatic clamping part 1 in this application is arranged at a position of the cylinder 1051 close to the piston rod 1053 , and the air outlet 102 of the pneumatic clamping part 1 is arranged at a position of the cylinder 1051 away from the piston rod 1053 .
[0026] In practice, when the pneumatic clamping unit 1 is powered on, the first switch 2021 and the second switch 2022 are in the on state, while the third switch 2023 and the fourth switch 2024 are in the off state. Air is introduced from the outlet of the first switch 2021 into the air inlet 101 of the pneumatic clamping unit 1. The air pushes the piston rod 1053 away from the retractable jaws 103, thereby retracting the retractable jaws 103. If the retractable jaws 103 need to be extended, the air can be discharged from the air outlet 102 of the pneumatic clamping unit 1 through the second switch 2022.
[0027] When the pneumatic clamping unit 1 is powered off, the first switch 2021 and the second switch 2022 are closed, while the third switch 2023 and the fourth switch 2024 are on. Air can flow into the air outlet 102 of the pneumatic clamping unit 1 through the inlet of the third switch 2023. The air pushes the piston rod 1053 toward the retractable jaws 103, thereby extending the retractable jaws 103 from the housing 104. If the retractable jaws 103 need to be retracted, the air can be discharged from the air inlet 101 of the pneumatic clamping unit 1 through the fourth switch 2024.
[0028] Illustratively, the clamping portion in the present application may further include a guardrail, the pneumatic clamping portion is located within the guardrail, and the portion of the gas transmission portion away from the pneumatic clamping portion is disposed on the guardrail, to facilitate operation and reduce safety hazards.
[0029] The present application also provides a cutting device, which includes the above-mentioned clamping device, so that different clamping depths can be achieved under power-off conditions.
