DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1 , 2 As shown, a square tube packaging device includes a support platform 1 and two rolling mechanisms, and the two rolling mechanisms are arranged on the left and right sides of the support platform 1 opposite to each other.

[0027] Each rolling mechanism includes a lifting element 8, a transverse thrust element 2, a base 3, a bracket 4, two guide rollers 5 and a pressure roller 6, wherein the lifting element 8 is arranged below the support platform 1, and the lifting element 8 is preferably a cylinder or an electric push rod or a hydraulic push rod, and the push rod of the lifting element 8 passes through the support platform 1, and the base 3 is installed on the push rod of the lifting element 8, i.e., the lifting end. The transverse thrust element 2 is installed on the base 3, and the transverse thrust element 2 is preferably a cylinder or an electric push rod or a hydraulic push rod, and the bracket 4 is installed on the push rod of the transverse thrust element 2, and the central axes of the two guide rollers 5 and the pressure roller 6 are arranged in parallel and are rotatably installed on the bracket 4, and the pressure roller 6 is arranged close to the top surface of the support platform 1, and the two guide rollers 5 are arranged side by side above the pressure roller 6, and the pressure roller 6 is located outside the two guide rollers 5, that is, the distance from the pressure roller 6 to the transverse thrust element 2 in the horizontal direction is greater than the distance from the two guide rollers 5 to the transverse thrust element 2, and the outer circumferential surfaces of the two guide rollers 5 are in close contact.

[0028] The structural relationship between the two guide rollers 5 in each rolling mechanism is as follows: Figure 3 As shown, two guide rollers 5 are arranged side by side with their outer circumferential surfaces tightly touching each other, and an annular groove 51 is provided on the circumferential surface of one of the guide rollers 5. The setting of the annular groove 51 enables the two guide rollers 5 to form a guide channel 52 for the strapping tape to pass through at the position of the annular groove.

[0029] The structure of the pressure roller 6 is as follows: Figure 4 As shown, the outer circumferential surface of the pressure roller 6 is provided with a limiting annular groove 61 corresponding to the guide channel 52, the groove depth of the limiting annular groove 61 is less than the thickness of the strapping tape, and the groove width corresponds to the width of the strapping tape. When the pressure roller 6 rolls the strapping tape, the limiting annular groove 61 limits the stretching direction of the strapping tape, further limits the position of the strapping tape, prevents the strapping tape from being skewed, and ensures the bundling and packaging effect.

[0030] In the utility model, the top surface of the support platform 1 is provided with a groove 102 corresponding to the pressure roller 6, the pressure roller 6 lies in the groove 102, and the center of the pressure roller 6 is not higher than the top surface of the support platform 1. This structure ensures that the rolling point of the pressure roller 6 is at the intersection of the side and bottom of the square tube stack, that is, the right angle position below the square tube stack. At this position, the pressure roller 6 rolls the strapping tape to deform it, thereby improving the adhesion between the strapping tape and the square tube stack and improving the strapping stability of the strapping tape.

[0031] In the present invention, a positioning groove 101 corresponding to the strapping tape is provided on the top surface of the support platform 1, and the position of the positioning groove 101 corresponds to the guide channel 52. This structure facilitates the placement and fixing of the strapping tape, and improves the convenience of packaging.

[0032] In the utility model, the bracket 4 is provided with a proximity switch 7 at the position where the pressure roller 6 is installed, and the lifting element 8, the horizontal pushing element 2 and the proximity switch 7 are all electrically connected to the controller. The proximity switch 7 detects the distance between the pressure roller 6 and the side of the square tube pile, so that the controller can control the action of the horizontal pushing element 2. For example, after the device is turned on, the push rod of the horizontal pushing element 2 extends, driving the bracket 4 and the two guide rollers 5 and a pressure roller 6 on the bracket to move toward the square tube pile. When the distance from the proximity switch 7 to the square tube pile is the set distance, the controller controls the horizontal pushing element 2 to stop extending its push rod, and at this time the position of the pressure roller 6 is just the position where it can roll the strapping tape along the side of the square tube pile.

[0033] The operation process of the utility model is as follows: first, the strapping tape 9 of appropriate length is cut according to the size of the square tube stack, and the cut strapping tape is placed in the limiting groove 101 of the support platform 1, such as Figure 5 As shown, the two ends of the strapping belt 9 pass through the outside of the pressure rollers 6 of the rolling mechanism on both sides of the support platform, and then pass through the guide channels 52 respectively, and the square tube stack 10 is placed on the support platform 1. The push rod of the horizontal pushing element 2 extends until the pressure roller 6 presses the strapping belt 9 to the side of the square tube stack 10, and the push rod of the horizontal pushing element 2 stops extending. At this time, the strapping belt 9 passes through the limiting ring groove 61 of the pressure roller 6 and is limited by the limiting ring groove 61. Then the lifting element 8 is opened and the base 2 is lifted. During the upward movement of the base 2, the pressure roller 6 rolls the strapping belt 9 to make it completely attached to the side of the square tube stack 10. The two guide rollers 5 control the strapping belt 9 to stretch vertically upward only, so as to realize vertical packaging. When the pressure roller 6 rises to the top of the square tube stack 10, as shown in FIG. Figure 6 As shown, the lifting element 8 stops the lifting action, the push rod of the horizontal pushing element 2 extends forward, driving the bracket 4 to move forward, and the pressure roller 6 rolls the packing tape 9 in the horizontal direction to attach the packing tape 9 to the top surface of the square tube stack 10, thereby completing the wrapping of the square tube stack 10 with the packing tape 9, and using tools to clamp the head and tail ends of the packing tape, the push rods of the horizontal pushing element 2 and the lifting element 8 retract, and the pressure roller 6 detaches from the square tube stack 10, and the head and tail ends of the packing tape are connected and fixed, completing the packing operation of the square tube stack 10.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
