Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink tube drying, in particular to a heat shrink tube drying machine with a limiting mechanism. Background Art

[0002] Heat shrink tubing is a special polyolefin heat shrink tubing. Heat shrink tubing is generally used at the interface of the wiring harness. It uses the high-temperature shrinkage characteristics to tightly wrap the heat shrink tubing between the metal conductor and the insulating jacket through drying, thereby improving the insulation performance and production efficiency of the wiring harness.

[0003] According to an automatic heat shrink tube drying machine disclosed (Announcement No.: CN213811589U), the above application uses a tray to carry wire harnesses with heat shrink tubes, the wire harnesses are arranged in a row on the tray, and the heat shrink tubes are in a straight line. The tray is transported by a conveyor belt to move the heat shrink tubes to the bottom of a drying spray gun, and the drying spray gun moves on the drying rack through the spray gun rack to dry the heat shrink tubes in a straight line, thereby realizing automatic drying.

[0004] However, in actual use of the above equipment, the wire harnesses are directly arranged and placed above the tray. When the drying spray gun is started to dry the wire harnesses below it, a certain amount of wind will be generated, which may cause the wire harnesses to shift on the tray, thereby causing the part of the wire harness to be dried to move, which will not only affect the drying effect of the wire harnesses, but also affect the processing efficiency. In view of this, we propose a heat shrink tube drying function machine with a limiting mechanism. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a heat shrink tube drying machine with a limiting mechanism, including a conveyor belt 1, a mounting frame 2 is arranged on the outside of the conveyor belt 1, a drying component 3 is arranged inside the mounting frame 2, a tray 4 is arranged on the upper surface of the conveyor belt 1, the wire harness is placed above the tray 4, the tray 4 is transported to the bottom of the drying component 3 by the conveyor belt 1, and then the drying component 3 is started to dry the wire harness, so that the heat shrink tube is tightly wrapped between the metal conductor and the insulating jacket, and a limiting component is arranged inside the tray 4.

[0025] The limiting assembly includes: a groove 501, a screw 503, a slide groove 506 and a limiting plate 509. The groove 501 is opened on the inner bottom surface of the tray 4. There are a plurality of grooves 501, and the plurality of grooves 501 are opened in a linear array on the inner bottom surface of the tray 4. The inner part of the groove 501 is rotatably connected with a roller 502, and the wire harness can be placed above the roller 502. Two adjacent rollers 502 will limit the wire harness. The screw 503 is rotatably installed on the inner bottom surface of the tray 4. A connecting block 504 is fixedly installed on the top of the screw 503. When the connecting block 504 rotates, it can drive the screw 503 to rotate synchronously.

[0026] The outer side of the screw rod 503 is threadedly connected to a movable plate 505, and the outer wall of the movable plate 505 fits against the inner wall of the tray 4. The inner wall of the tray 4 can guide and limit the movement of the movable plate 505, so that the movable plate 505 can only perform linear motion in the up and down directions. When the screw rod 503 rotates, it can perform linear motion in the up and down directions under the limit inside the tray 4. The slide groove 506 is opened on the inner bottom surface of the movable plate 505, and an electric push rod 507 is fixedly installed on the left inner wall surface of the slide groove 506. A slider 508 is fixedly installed on the right end of the electric push rod 507. When the electric push rod 507 starts to drive the slider 508 to perform linear motion in the left and right directions, the slide groove 506 can limit the movement of the slider 508, so that the movement of the slider 508 remains stable, and the slider 508 is slidably connected to the inside of the slide groove 506.

[0027] The limiting plate 509 is fixedly installed at the bottom end of the slider 508, and a rubber plate 510 is fixedly installed on the bottom surface of the limiting plate 509. The rubber plate 510 is located directly above the rotating roller 502. When the movable plate 505 moves downward, the limiting plate 509 can be driven to move downward synchronously. At this time, the limiting plate 509 can limit the wiring harness to prevent the drying component 3 from starting to dry and heat the heat shrink tube, generating wind force that causes the wiring harness to deviate and affect the drying of the wiring harness. When the limiting plate 509 moves downward, the rubber plate 510 can be driven to move synchronously. The set rubber plate 510 can avoid hard contact with the wiring harness and reduce the influence of extrusion on the deformation of the wiring harness.

[0028] During the heating process, the electric push rod 507 can be started to drive the slider 508 to move to the right, thereby driving the limiting plate 509 and the rubber plate 510 to move to the right. In the process of the rubber plate 510 limiting the wiring harness, when the rubber plate 510 moves to the right, the wiring harness can be driven to rotate with the cooperation of the roller 502, so that the drying component 3 can perform a comprehensive drying treatment on the connection, avoiding the situation where only one side of the wiring harness can be dried after the wiring harness is limited, affecting the drying effect.

[0029] A screw hole 601 is provided on the inner bottom surface of the tray 4, and a bolt 602 is connected to the internal thread of the screw hole 601. The bolt 602 is located directly below the movable plate 505. The bolt 602 can limit the movement of the movable plate 505. The staff can adjust the height of the bolt 602 exposed from the tray 4 by rotating the bolt 602. At this time, the bolt 602 can limit the moving distance of the movable plate 505 to prevent the movable plate 505 from moving downward too much, resulting in excessive extrusion and deformation of multiple wiring harnesses.

[0030] The wire harness is placed inside the tray 4 when in use, so that the wire harness is above the roller 502, and the bolt 602 is rotated to adjust the exposed height. Then the staff can rotate the connecting block 504 to drive the screw 503 to rotate, thereby driving the movable plate 505 to move downward under the limit of the inner wall of the tray 4, so that the rubber plate 510 is in contact with the upper surface of the wire harness, and the wire harness is limited to avoid displacement of the wire harness due to the wind force sprayed by the drying component 3 during the drying and heating process, thereby affecting the drying effect. The conveyor belt 1 is started to drive the tray 4 to move to the bottom of the drying component 3, and the wire harness is dried by the drying component 3. During the drying process, the electric push rod 507 can be started to drive the slider 508 to move to the right, thereby driving the rubber plate 510 to move to the right synchronously, and driving the wire harness to rotate by cooperating with the roller 502, so that the drying component 3 can perform comprehensive drying on the wire harness, thereby avoiding that only one side of the wire harness can be dried due to the limited position of the wire harness, thereby affecting the drying efficiency.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
