[0002] In the related art, the waste removal pipeline of the die-cutting machine is usually connected to the basic system pipeline in a split connection method. Specifically, a rubber hose is first connected to the connection between the waste removal pipeline of the die-cutting machine and the basic system pipeline, and then it is locked by a clamp and sealed with tape to achieve a sealed connection between the waste removal pipeline of the die-cutting machine and the basic system pipeline. However, the rubber hose is constantly subjected to friction during the waste recycling process. The workshop environment is dry, and static electricity is easily generated due to friction, causing the rubber hose to absorb waste and cause blockage. At the same time, the rubber hose is not easy to disassemble, making the disassembly work time-consuming and labor-intensive. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0028] like Figures 1 to 4 As shown, an embodiment of the present application provides a clamp. The clamp includes a first clamp piece 10 and a second clamp piece 20. The first clamp piece 10 is rotatably connected to the second clamp piece 20. A first sealing portion 30 extending along the circumference of the first clamp piece 10 is configured on the side facing the second clamp piece 20. A second sealing portion 40 extending along the circumference of the second clamp piece 20 is configured on the side facing the first clamp piece 10. When the clamp is in a closed state, the opposite ends of the first sealing portion 30 respectively abut against the opposite ends of the second sealing portion 40.

[0029] In the embodiment of the present application, a circumferentially extending first sealing portion 30 is provided on the side of the first clamp sheet 10 facing the second clamp sheet 20, and a circumferentially extending second sealing portion 40 is provided on the side of the second clamp sheet 20 facing the first clamp sheet 10. When the first clamp sheet 10 and the second clamp sheet 20 are enclosed outside the pipeline, the first sealing portion 30 and the second sealing portion 40 abut against each other, thereby forming a sealed connection. This allows the connection between the two pipelines to be directly sealed, replacing the rubber hose seal used in traditional solutions and facilitating quick assembly and disassembly of the two pipelines.

[0030] It is understood that the first sealing portion 30 and the second sealing portion 40 are located at the same axial position of the clamp, so that the ends of the first sealing portion 30 and the second sealing portion 40 can abut against each other when the clamp is closed. As a result, the first sealing portion 30 and the second sealing portion 40 can form a structure similar to a sealing ring, achieving a good sealing effect.

[0031] When both the first sealing portion 30 and the second sealing portion 40 are provided as one, the first sealing portion 30 and the second sealing portion 40 can be positioned directly opposite the connection between the two pipelines. When the clamp is in the closed state, the first sealing portion 30 and the second sealing portion 40 can just seal the connection between the two pipelines, thereby achieving a sealed connection between the two pipelines.

[0032] When two first sealing parts 30 and two second sealing parts 40 are provided, the connection point of the two pipelines can be located in the space between the two first sealing parts 30 (also the space between the two second sealing parts 40). Thus, by utilizing the cooperation of the two sets of first sealing parts 30 and second sealing parts 40, the space between them forms a sealing area, thereby achieving a seal at the connection point of the two pipelines.

[0033] like Figure 1 As shown, one end of the first clamp sheet 10 is rotatably connected to one end of the second clamp sheet 20, and the other end of the first clamp sheet 10 and the other end of the second clamp sheet 20 can be fixed by a fastener 80. The fastening effect of the fastener 80 not only ensures the reliable engagement of the first clamp sheet 10 and the second clamp sheet 20, but also enables the first sealing portion 30 and the second sealing portion 40 to be in close contact with the outer surface of the pipeline, thereby ensuring that the first sealing portion 30 and the second sealing portion 40 are subjected to sufficient force, thereby achieving a good sealing effect.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, the first clamp sheet 10 and the second clamp sheet 20 are both configured as semicircular. Correspondingly, the first sealing portion 30 and the second sealing portion 40 are also configured as semicircular. Alternatively, the first clamp sheet 10 and the second clamp sheet 20 can also be configured as other shapes such as an ellipse. The shapes of the first clamp sheet 10 and the second clamp sheet 20 can be selected based on the shape of the pipeline to be embraced, ensuring that the first clamp sheet 10 and the second clamp sheet 20 can be embraced on the pipeline after being closed and connected. Among them, the first sealing portion 30 and the second sealing portion 40 are also adaptively selected based on the shapes of the first clamp sheet 10 and the second clamp sheet 20.

[0035] In some embodiments, the first clamp sheet 10 and the second clamp sheet 20 have the same length and thickness, and the first sealing portion 30 and the second sealing portion 40 have the same length, thickness, and width.

[0036] In some embodiments, the first sealing portion 30 can be bonded to the inner surface of the first clamp sheet 10 (i.e., the side of the first clamp sheet 10 facing the second clamp sheet 20) by adhesive. Alternatively, the first sealing portion 30 can also be connected to the inner surface of the first clamp sheet 10 by hot melting. Alternatively, the first sealing portion 30 can also be connected to the inner surface of the first clamp sheet 10 by screw fixing. Alternatively, a circumferentially extending groove can be provided on the inner surface of the first clamp sheet 10, and the first sealing portion 30 can be clamped into the groove.

[0037] In some embodiments, the second sealing portion 40 can be bonded to the inner surface of the second clamping sheet 20 (i.e. the side of the second clamping sheet 20 facing the first clamping sheet 10) by an adhesive. Alternatively, the second sealing portion 40 can also be connected to the inner surface of the second clamping sheet 20 by means of heat melting. Alternatively, the second sealing portion 40 can also be connected to the inner surface of the second clamping sheet 20 by means of screwing. Alternatively, the inner surface of the second clamping sheet 20 can be provided with a clamping groove extending in the circumferential direction, and the second sealing portion 40 is clamped in the clamping groove.

[0038] Referring to Figure 2 and Figure 3 In some embodiments, the first sealing portion 30 is provided as at least two. The at least two first sealing portions 30 are arranged axially spaced apart along the first clamping sheet 10. The second sealing portion 40 is provided as at least two. The at least two second sealing portions 40 are arranged axially spaced apart along the second clamping sheet 20. The first sealing portion 30 and the second sealing portion 40 correspond to each other.

[0039] It can be understood that when the first sealing portion 30 and the second sealing portion 40 are provided as at least two, a plurality of layers of sealing can be formed along the axial direction of the clamp, which can improve the sealing performance of the clamp. At the same time, the connection of the two pipelines can be located between the at least two first sealing portions 30, so that the first sealing portion 30 and the second sealing portion 40 do not need to be aligned with the connection of the two pipelines. When the clamp is clamped between the two pipelines, the connection of the two pipelines can be sealed.

[0040] For example, the first sealing portion 30 and the second sealing portion 40 are each provided as two. The two first sealing portions 30 are respectively located at the two ends of the first clamping sheet 10 in the axial direction. Correspondingly, the two second sealing portions 40 are respectively located at the two ends of the second clamping sheet 20 in the axial direction. At this time, the region of the clamp between the two first sealing portions 30 / two second sealing portions 40 is a sealing region, thereby achieving sealing of the connection of the two pipelines.

[0041] The first sealing portion 30 and the second sealing portion 40 correspond to each other means that the number of the first sealing portion 30 is the same as the number of the second sealing portion 40, and the position of each first sealing portion 30 in the axial direction of the clamp is the same as the position of each second sealing portion 40 in the axial direction of the clamp.

[0042] For example, Figure 2As shown, in some embodiments, a third sealing portion 50 and a fourth sealing portion 60 are configured on the first clamp piece 10. The third sealing portion 50 and the fourth sealing portion 60 both extend axially along the first clamp piece 10. The third sealing portion 50 and the fourth sealing portion 60 are both configured to seal the connection between the first clamp piece 10 and the second clamp piece 20 when the clamp is in a closed state. The opposite ends of the third sealing portion 50 are respectively connected to the first ends of the two first sealing portions 30 located at the edge. The opposite ends of the fourth sealing portion 60 are respectively connected to the second ends of the two first sealing portions 30 located at the edge.

[0043] It is understood that a gap may exist at the pivotal connection between one side of the first clamping piece 10 and the second side of the second clamping piece 20. The second side of the first clamping piece 10 and the second side of the second clamping piece 20 are joined and locked together by the fastener 80, and a gap may also exist at this locked side. In the embodiment of the present application, the third sealing portion 50 and the fourth sealing portion 60 respectively seal the two gaps to ensure a good sealing effect when the clamps are engaged with the two pipelines.

[0044] Since the third sealing portion 50 and the fourth sealing portion 60 are used to seal the connection between the first clamp piece 10 and the second clamp piece 20 when the clamp is in a closed state, the third sealing portion 50 and the fourth sealing portion 60 are respectively located at the two ends of the first clamp piece 10 in the circumferential direction, that is, the first side and the second side of the first clamp piece 10.

[0045] The two ends of the third sealing portion 50 are respectively connected to the first ends of the two first sealing portions 30 located at the edge, so that the third sealing portion 50 covers the entire axial area of ​​the first clamping piece 10. The two ends of the fourth sealing portion 60 are respectively connected to the second ends of the two first sealing portions 30 located at the edge, so that the fourth sealing portion 60 covers the entire axial area of ​​the first clamping piece 10.

[0046] In some embodiments, the third sealing portion 50 and the fourth sealing portion 60 may be integrally formed with at least two first sealing portions 30, and the at least two first sealing portions 30, the third sealing portion 50, and the fourth sealing portion 60 may be connected together to the inner surface of the first clamp sheet 10. Alternatively, the third sealing portion 50 and the fourth sealing portion 60 may only abut against the first sealing portion 30, and after being embraced, they are squeezed to achieve a good sealing effect.

[0047] In some embodiments, a fifth sealing portion and a sixth sealing portion are configured on the second clamping piece 20. Both the fifth sealing portion and the sixth sealing portion extend axially along the second clamping piece 20. Both the fifth sealing portion and the sixth sealing portion are configured to seal the connection between the first clamping piece 10 and the second clamping piece 20 when the clamp is in a closed state. The opposite ends of the fifth sealing portion are respectively connected to the first ends of the two second sealing portions 40 located at the edge. The opposite ends of the sixth sealing portion are respectively connected to the second ends of the two second sealing portions 40 located at the edge.

[0048] It is understood that a gap may exist at the pivotal connection between one side of the first clamping piece 10 and one side of the second clamping piece 20. The second side of the first clamping piece 10 and the second side of the second clamping piece 20 are butted together and locked together by the fastener 80, and a gap may also exist at this locked side. In the embodiment of the present application, the fifth and sixth sealing portions respectively seal the two gaps to ensure a good sealing effect when the clamps are engaged with the two pipelines.

[0049] Since the fifth sealing portion and the sixth sealing portion are used to seal the connection between the first clamp piece 10 and the second clamp piece 20 when the clamp is in a closed state, the fifth sealing portion and the sixth sealing portion are respectively located at the two circumferential ends of the second clamp piece 20, i.e., the first side and the second side of the second clamp piece 20.

[0050] The two ends of the fifth sealing portion are respectively connected to the first ends of the two second sealing portions 40 located at the edge, so that the fifth sealing portion covers the entire axial area of ​​the second clamping plate 20. The two ends of the sixth sealing portion are respectively connected to the second ends of the two second sealing portions 40 located at the edge, so that the sixth sealing portion covers the entire axial area of ​​the second clamping plate 20.

[0051] In some embodiments, the fifth and sixth sealing portions may be integrally formed with at least two second sealing portions 40, and the at least two second sealing portions 40, the fifth and sixth sealing portions may be connected together to the inner surface of the second clamping piece 20. Alternatively, the fifth and sixth sealing portions may only abut against the second sealing portions 40, and after being embraced, they may be squeezed to achieve a good sealing effect.

[0052] In some embodiments, when the third sealing portion 50 and the fourth sealing portion 60 are provided on the first clamp sheet 10, the fifth and sixth sealing portions may not be provided on the second clamp sheet 20. When the third sealing portion 50 and the fourth sealing portion 60 are not provided on the first clamp sheet 10, the fifth and sixth sealing portions may need to be provided on the second clamp sheet 20. Alternatively, the third sealing portion 50 and the fourth sealing portion 60 may be provided on the first clamp sheet 10, and the fifth and sixth sealing portions may be provided on the second clamp sheet 20.

[0053] As shown in FIG. 1, a first clamping piece 10 and a second clamping piece 20 are provided. The first clamping piece 10 is configured with a first connecting portion 110. The second clamping piece 20 is configured with a second connecting portion 210. The first connecting portion 110 is rotationally connected with the second connecting portion 210. Figure 1 As shown in FIG. 1, a first clamping piece 10 and a second clamping piece 20 are provided. The first clamping piece 10 is configured with a first connecting portion 110. The second clamping piece 20 is configured with a second connecting portion 210. The first connecting portion 110 is rotationally connected with the second connecting portion 210.

[0054] It can be understood that, through the rotational connection between the first connecting portion 110 and the second connecting portion 210, the rotational connection of the first clamping piece 10 and the second clamping piece 20 is realized.

[0055] In some embodiments, the first connecting portion 110 and the second connecting portion 210 can form a structure similar to a hinge, so as to realize the rotational connection of the two.

[0056] As shown in FIG. 1, a first clamping piece 10 and a second clamping piece 20 are provided. The first clamping piece 10 is configured with a first connecting portion 110. The second clamping piece 20 is configured with a second connecting portion 210. The first connecting portion 110 is rotationally connected with the second connecting portion 210. Figure 2 and Figure 3 As shown in FIG. 1, a first clamping piece 10 and a second clamping piece 20 are provided. The first clamping piece 10 is configured with a first connecting portion 110. The second clamping piece 20 is configured with a second connecting portion 210. The first connecting portion 110 is rotationally connected with the second connecting portion 210.

[0057] It can be understood that, based on the threaded shaft 70 being threaded in the first connecting channel 120 and the second connecting channel 220, the rotational connection of the first connecting portion 110 and the second connecting portion 210 can be realized through the threaded shaft 70. Specifically, the threaded shaft 70 can be rotationally connected with the first connecting channel 120, and the threaded shaft 70 can be fixedly connected with the second connecting channel 220. Thus, by rotating the threaded shaft 70 in the first connecting channel 120, the rotational connection of the first connecting portion 110 and the second connecting portion 210 is realized. Alternatively, the threaded shaft 70 can be rotationally connected with the second connecting channel 220, and the threaded shaft 70 can be fixedly connected with the first connecting channel 120. Thus, by rotating the threaded shaft 70 in the second connecting channel 220, the rotational connection of the first connecting portion 110 and the second connecting portion 210 is realized. Alternatively, the threaded shaft 70 can be rotationally connected with the first connecting channel 120 and the second connecting channel 220, and the rotational connection of the first connecting portion 110 and the second connecting portion 210 can also be realized.

[0058] For example, after the first connecting portion 110 is aligned with the second connecting portion 210, the first connecting channel 120 and the second connecting channel 220 are in communication. One end of the threaded shaft 70 is threaded into the second connecting channel 220 and the first connecting channel 120 from one end of the second connecting channel 220, and the other end of the threaded shaft 70 is connected with a limiting end, which abuts against the second connecting portion 210. Thus, the assembly of the threaded shaft 70 is realized.

[0059] In some embodiments, the outer surface of the first clamp sheet 10 is constructed with a connecting plate extending in the axial direction, and the first connecting portion 110 is connected to the lower surface of the connecting plate. The first connecting portion 110 is located in the middle of the connecting plate. Two first connecting channels 120 can be formed in the first connecting portion 110. The two first connecting channels 120 form openings at opposite ends of the first connecting portion 110, respectively. Alternatively, only one first connecting channel 120 is provided in the first connecting portion 110, and the one connecting channel forms openings at opposite ends of the first connecting portion 110. The outer surface of the second clamp sheet 20 is constructed with two second connecting portions 210 spaced apart, and the two second connecting portions 210 are located at opposite ends of the first connecting portion 110, respectively. Thus, the two second connecting portions 210, two rotating shafts 70 and one first connecting portion 110 can be used to realize the rotational connection between the first clamp sheet 10 and the second clamp sheet 20.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the first clamp piece 10 is configured with a third connection portion 130 , and the second clamp piece 20 is configured with a fourth connection portion 230 . The third connection portion 130 and the fourth connection portion 230 are connected by a fastener 80 .

[0061] It is understandable that the third connection part 130 and the fourth connection part 230 are locked by the fastener 80, so that the first clamp piece 10 and the second clamp piece 20 can be locked, ensuring that the clamp can stably and reliably fit the connection between the two pipelines.

[0062] In some embodiments, the third connection portion 130 is configured with a mounting notch 140. The fourth connection portion 230 is configured with a fastening hole 240. Figure 4 As shown, the fastener 80 includes a connecting section 810, a limiting section 820, and a gripping section 830, which are connected in sequence. The connecting section 810 passes through the mounting notch 140 and is connected to the fastening hole 240. The limiting section 820 abuts against the third connecting portion 130, and the diameter of the limiting section 820 is greater than the width of the mounting notch 140.

[0063] It is understood that the operator can hold the gripping section 830 to insert the connecting section 810 into the installation notch 140 and the fastening hole 240. After the stopper abuts the third connecting section 130, the gripping section 830 is further rotated to securely lock the connecting section 810 between the third connecting section 130 and the fourth connecting section 230. This ensures that the clamp can stably and reliably engage the connection between the two pipes.

[0064] For example, the third connection portion 130 may be configured to be U-shaped, thereby forming a mounting notch 140 . The fastening hole 240 on the fourth connection portion 230 is aligned with the mounting notch 140 .

[0065] The fastening hole 240 can be a threaded hole, and the outer surface of the connecting segment 810 is provided with external threads. Based on the threaded connection between the connecting segment 810 and the fastening hole 240, locking and fixing are achieved.

[0066] When the operator holds the holding segment 830, the connecting segment 810 can be inserted into the mounting gap 140 and threaded into the fastening hole 240 by rotating. As the connecting segment 810 is continuously screwed in, the limiting segment 820 gradually approaches the third connecting portion 130 and abuts against the third connecting portion 130. Because the diameter of the limiting segment 820 is greater than the width of the mounting gap 140, the limiting segment 820 cannot pass through the mounting gap 140. When the limiting segment 820 continues to abut against the third connecting portion 130 and the holding segment 830 is further rotated to control the connecting segment 810, the fourth connecting portion 230 can be pulled towards the third connecting portion 130 based on the threaded connection between the connecting segment 810 and the fastening hole 240, until the first clamp plate 10 and the second clamp plate 20 are completely fitted. In this way, the reliability and sealing performance of the connection between the first clamp plate 10 and the second clamp plate 20 can be ensured.

[0067] In some embodiments, the third connecting portion 130 can be provided as at least two, and the at least two third connecting portions 130 are arranged on the first clamp plate 10 in an axial direction. The fourth connecting portion 230 on the second clamp plate 20 corresponds to the third connecting portion 130 on the first clamp plate 10 one by one.

[0068] In some embodiments, the holding portion can be triangular. Of course, the holding portion can also be circular, elliptical or any other shape, as long as the holding portion can be easily held.

[0069] In some embodiments, the third connecting portion 130 is provided with the fastening hole 240. The fourth connecting portion 230 is provided with the mounting gap 140. The fastener 80 includes the connecting segment 810, the limiting segment 820 and the holding segment 830 connected in sequence. The connecting segment 810 passes through the mounting gap 140 and is connected with the fastening hole 240. The limiting segment 820 abuts against the fourth connecting portion 230, and the diameter of the limiting segment 820 is greater than the width of the mounting gap 140. In this way, the clamp can also be stably and reliably clamped on the connection between the two pipelines, and details are not described here.

[0070] In some embodiments, the first clamp plate 10 and the second clamp plate 20 both include conductive clamp plates.

[0071] It is understood that since both the first clamp sheet 10 and the second clamp sheet 20 are conductive, even if static electricity is generated by friction, the first clamp sheet 10 and the second clamp sheet 20 can quickly transfer the static electricity. This prevents static electricity from attracting waste materials at the locations corresponding to the first sealing portion 30 and the second sealing portion 40 in the pipeline, causing blockage.

[0072] For example, the first clamp piece 10 and the second clamp piece 20 are both made of stainless steel. This allows the first clamp piece 10 and the second clamp piece 20 to have good electrical conductivity, effectively transmit current, and be less likely to accumulate static electricity, further preventing blockage caused by static electricity adsorption of waste materials.

[0073] The present application also provides a pipeline connection structure. The pipeline connection structure includes a first pipeline, a second pipeline, and a clamp as described in the aforementioned embodiment. The first pipeline and the second pipeline are connected. The clamp is connected to the connection between the first pipeline and the second pipeline.

[0074] In the embodiment of the present application, a circumferentially extending first sealing portion 30 is provided on the side of the first clamp sheet 10 facing the second clamp sheet 20, and a circumferentially extending second sealing portion 40 is provided on the side of the second clamp sheet 20 facing the first clamp sheet 10. When the first clamp sheet 10 and the second clamp sheet 20 are enclosed outside the pipeline, the first sealing portion 30 and the second sealing portion 40 abut against each other, thereby forming a sealed connection. This allows the connection between the first and second pipelines to be directly sealed, replacing the rubber hose seal used in traditional solutions and facilitating quick assembly and disassembly between the first and second pipelines.
