Technical Field
[0001] This utility model belongs to the field of outer sheath tube production technology, and specifically relates to a sealing and pinching device for outer sheath tube production. Background Technology
[0002] During the molding process of polyethylene outer protective tubes, the ends of the tube material need to be sealed and pinched shut. This means that the ends of the tube material are sealed by a device to prevent air leakage, which would affect the molding quality at the molding equipment. Currently, sealing and pinching devices generally require at least two people to operate, which is cumbersome and inconvenient to use. Utility Model Content
[0003] This invention provides a sealing and clamping device for the production of outer protective tubes, which can solve the problems pointed out in the background art.
[0004] A sealing and clamping device for producing outer protective tubes includes a base frame and a limiting frame connected to the base frame. A sliding component is provided below the base frame to provide limiting guidance for the device to slide back and forth linearly. One side of the limiting frame is a movable frame edge. One end of the movable frame edge is hinged to the limiting frame, and the other end is detachably connected to the limiting frame through a fixing member. A pressure plate is slidably connected inside the limiting frame. The pressure plate is driven to slide back and forth by a driving mechanism.
[0005] Preferably, both ends of the pressure plate along its length are provided with slide rails that are slidably connected to the limiting frame, allowing it to slide up and down repeatedly.
[0006] Preferably, the driving mechanism is a drive screw, which is threadedly rotatably connected to the limiting frame, and its lower end is rotatably connected to the pressure plate.
[0007] Preferably, the lower end of the movable frame is rotatably connected to the limiting frame via a rotating shaft, and its upper end is detachably connected to the limiting frame via a fixing member, which is a screw.
[0008] Preferably, the sliding assembly includes slide rails on both sides and several sliding wheels.
[0009] Preferably, a rubber pressure head is provided at the contact point between the pressure plate and the outer protective tube.
[0010] Beneficial effects: This utility model provides a sealing and pinching device for the production of outer protective tubes, which is easy to operate and use. Only one worker is needed to complete the entire operation, saving labor. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of this utility model.
[0012] Explanation of reference numerals in the attached figures:
[0013] The following are labeled in the diagram: Base frame 1; Limiting frame 2; Movable frame edge 21; Fixing component 3; Pressure plate 4; Drive mechanism 5; Slide rail component 6; Slide rail 71; Sliding wheel 72; Rubber pressure head 8. Detailed Implementation
[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0015] Example 1:
[0016] like Figure 1 As shown, a sealing and clamping device for producing outer protective tubes includes a base frame 1 and a limiting frame 2 connected to the base frame 1. A sliding component is provided below the base frame 1 to provide limiting guidance for the device to slide back and forth in a straight line. One side of the limiting frame 2 is a movable frame edge 21. One end of the movable frame edge 21 is hinged to the limiting frame 2, and the other end is detachably connected to the limiting frame 2 through a fixing member 3. A pressure plate 4 is slidably connected inside the limiting frame 2. The pressure plate 4 is driven to slide back and forth by a driving mechanism 5.
[0017] Specifically, both ends of the pressure plate 4 along its length are provided with slide rails 6 that are slidably connected to the limiting frame 2, allowing it to slide up and down reciprocally. The driving mechanism 5 is a drive screw, which is threadedly connected to the limiting frame 2, and its lower end is rotatably connected to the pressure plate 4. The lower end of the movable frame edge 21 is rotatably connected to the limiting frame 2 via a rotating shaft, and its upper end is detachably connected to the limiting frame 2 via a fixing member 3, which is a screw. The sliding assembly includes slide rails 71 on both sides and several sliding wheels 72. The slide rails 71 are fixed to the ground, and the sliding wheels 72 are located below the base frame 1, guiding the base frame 1 along the slide rails 71. That is, during the production process, the material tube continuously produces material, driving the device to move forward continuously along the slide rails 71.
[0018] In some embodiments, a rubber pressure head 8 is provided at the contact point between the pressure plate 4 and the outer protective tube. The cross-section of the rubber pressure head 8 can be an inverted trapezoid. The rubber pressure head 8 presses against the outer protective tube to ensure the clamping force is uniform and can also prevent the outer protective tube from being crushed.
[0019] The working principle of this utility model is as follows: After removing the fixing part 3, rotate the movable frame edge 21 outward to open it, put the end of the outer protective tube into the limiting frame 2, return the movable frame edge 21 to its original position, fix it by the fixing part 3, and press the outer protective tube by the driving mechanism 5 to seal its end. As the outer protective tube is continuously produced, it drives the device to move forward continuously along the slide rail 71.
[0020] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
