[0022] Embodiment:
[0023] As Figures 1-5As shown in the figure, this embodiment provides an automatic plastic strip wrapping device for a luggage wire frame, which includes a workbench 1, a wire frame 10, and a controller. At a corner of the rear end of the workbench 1, there is a sliding connection with an offset table 2 along a direction at an angle of 45 degrees to the horizontal. In the middle of the offset table 2, there is a rotating table 6 rotatably connected. At the top of the rotating table 6 and near the circular part, there is an expansion die 5 arranged horizontally. At the front end of the expansion die 5, there is a first pressing cylinder 7 fixedly installed. Inside the expansion die 5, a plastic strip 3 is inserted. The plastic strip 3 is wound inside a feeding device 4. The feeding device 4 is fixedly installed on one side of the top of the offset table 2. The cross-section of the plastic strip 3 is C-shaped, and its notch is expanded by passing through the expansion die 5. After the notch of the plastic strip 3 is expanded, it is inserted into one side of the wire frame 10 and then resumes its original shape. Along the horizontal direction at the rear end of the workbench 1, there is a servo motor slide 9 fixedly installed. The servo motor slide 9 is provided with a slide plate 91. At the top of the slide plate 91, there is a second pressing cylinder 8. On the top of the workbench 1 and matching the traveling track of the wire frame 10, there is a travel switch 11;
[0024] The wire frame 10 is placed between the tops of the workbench 1, the offset table 2, and the rotating table 6. The first pressing cylinder 7 presses and fixes the wire frame 10 and the plastic strip 3 on the top surface of the rotating table 6. The second pressing cylinder 8 presses and fixes the wire frame 10 and the plastic strip 3 on the top of the slide plate 91.
[0025] Specifically, as Figures 1-4 shown, to achieve full automation of this automatic plastic strip wrapping device 3, the electromagnetic gripper of the feeding device 12 sucks the wire frame 10 and places it on the workbench 1, and makes one side of it extend into the expansion die 5. At the same time, the plastic strip 3 is sent into the expansion die 5 through the feeding device 4 to expand the notch at its notch. Through the power of the feeding device 4 and its own elastic force to resume the original shape, the wire frame 10 is wrapped. At the same time, after the second pressing cylinder 8 on the slide plate 91 presses and fixes the plastic strip 3 and the wire frame 10, the controller controls the operation of the servo motor slide 9, so as to drive the slide plate 91 to move away from the rotating table 6, thereby driving the plastic strip 3 and the wire frame 10 to move forward synchronously. The plastic strip 3 wraps the wire frame 10 at the same time. After traveling for a period of time, the rear part of the wire frame 10 hits the travel switch 11, so that the controller controls the servo motor slide 9 to stop operating. At this time, the plastic strip 3 has wrapped one side of the wire frame 10;
[0026] Subsequently, the controller controls the rotary motor 61 to drive the rotary table 6 to rotate, so that the expanding die 5 rotates 90 degrees along the rounded corner of the wire frame 10 in an arc, and covers the wire frame 10 along the moving track. After the expanding die 5 stops rotating 90 degrees, the plastic strip 3 and the wire frame 10 are pressed together on the top of the rotary table 6 by the first pressing cylinder 7 fixedly installed at its front end. At the same time, the second pressing cylinder 8 is controlled to contract to release the wire frame 10, and then the rotary motor 61 is controlled to reset. Thus, due to the clamping force of the first pressing cylinder 7, the wire frame 10 rotates 90 degrees together with the rotary table 6. During this process, the controller controls the slide plate 91 to approach the rotary table 6. After the wire frame 10 stops rotating 90 degrees, after pressing the other side edge of the wire frame 10 on the top of the slide plate 91, the servo motor slide 9 drives the slide plate 91 and the second pressing cylinder 8 to drag the wire frame 10 forward again until it hits the travel switch 11 and stops, and then flips again. The above operation steps are cycled in turn until the starting end of the plastic strip 3 coincides with the end. The hot melting device 81 arranged at the telescopic end of the second pressing cylinder 8 is controlled by the controller to melt and fix the starting end and the plastic strip 3. At this time, the offset table 2 is pushed away from the workbench 1 in a direction of 45 degrees obliquely by controlling the push-pull cylinder 22, so that the plastic strip 3 is separated from the wire frame 10 and falls into the shearing device 82. The controller controls the shearing device 82 to cut it, and after the excess plastic strip 3 is wound back to the starting state by the winding device 4, the covering operation of the next wire frame 10 can be carried out;
[0027] Through the above structural settings, the full-automatic operation of wrapping the plastic strip 3 on the wire frame 10 can be realized, thus effectively improving the production efficiency of the wire frame 10 products, and at the same time greatly reducing the amount of manual participation, thereby saving a large amount of labor costs for the enterprise; at the same time, through the precise structural design, the production consistency and product quality of the wire frame 10 products are effectively guaranteed.
[0028] In a preferred embodiment of the present utility model, further, the expanding die 5 is sequentially composed of an insertion cylinder 51, a connecting block 52 and an expanding cone groove 53 along the transmission direction. The insertion cylinder 51 is a hollow cylindrical structure, and a connecting block 52 is fixedly connected to one side inside it along the central axis direction. The rear end of the connecting block 52 is fixedly connected to the conical head end 531 of the expanding cone groove 53. One side of the rear end of the insertion cylinder 51 is fixedly connected to a baffle 54. There is a gap between the baffle 54 and the back of the expanding cone groove 53. The wire rod of the wire frame 10 is located inside the expanding cone groove 53, and the plastic strip 3 after the expanding notch passes through the gap between the baffle 54 and the expanding cone groove 53 and is inserted into the wire frame 10.
[0029] Specifically, as Figure 5As shown in the figure, by inserting the plastic strip 3 into the insertion cylinder 51, inserting the insertion cylinder 51 into the conical head end 531 of the expansion conical groove 53, and guiding through the shape of the conical head end 531, the notch of the plastic strip 3 is expanded, and the plastic strip 3 is prevented from spreading out and falling off through the gap between the baffle 54 and the expansion conical groove 53, resulting in the failure of the steel wire frame 10 to be coated.
[0030] In a preferred embodiment of the present invention, further, at a corner of the bottom of the workbench 1, two guide rods 21 are arranged side by side along a direction at an angle of 45 degrees with the horizontal direction. The offset table 2 is slidably connected between the two guide rods 21. A push-pull cylinder 22 is fixedly installed at the bottom of the workbench 1 and between the two guide rods 21. The end of the telescopic shaft of the push-pull cylinder 22 is fixedly installed with the bottom of the offset table 2. By extending the offset table 2 out of the workbench 1, the plastic strip 3 is separated from the steel wire frame 10, facilitating the cutting of the plastic strip 3.
[0031] In a preferred embodiment of the present invention, further, a cutting device 82 is arranged at the top of the sliding table plate 91 and near the second pressing cylinder 8. The end of the telescopic shaft of the second pressing cylinder 8 is fixedly installed with a hot melting device 81.
[0032] In a preferred embodiment of the present invention, further, the middle of the rotating table 6 is fixedly installed with the output shaft of the rotating motor 61. The rotating motor 61 is fixedly installed at the bottom of the offset table 2. In another solution of this embodiment, a cylinder can be hinged at the bottom of the offset table 2, and the end of the output shaft of the cylinder is hinged with one side of the bottom of the rotating table 6, so as to control the rotation angle of the rotating table 6 through the telescopic movement of the cylinder.
[0033] In a preferred embodiment of the present invention, further, a feeding device 12 is arranged on one side of the workbench 1. The feeding device 12 is provided with an electromagnetic suction claw, and the feeding device 12 adsorbs the steel wire frame 10 through the electromagnetic suction claw.
