In the packaging process of the box body, after the cover of the box body covers the box body, the edge covered by the cover needs to be welted, when the I-shaped structure is used for corner fitting, the vertical side surface of the cover covering the box body can be used as one side to be subjected to corner fitting, and the vertical side of the part, corresponding to the side surface of the cover, of the box body is used as the other side to be subjected to corner fitting, so that the I-shaped structure penetrates through the box body and the vertical side surface of the cover to be fixed; the top surface of the cover covering the box body can be used as one side to be subjected to corner fitting, and the vertical side of the part, corresponding to the side surface of the cover, of the box body can be used as the other side to be subjected to corner fitting, so that the I-shaped structure penetrates through the box body, the side surface of the cover and the top surface of the cover to be subjected to corner fitting and fixing.

In this embodiment, when the box body is welted by using the i-shaped structure, at least one side of the welting is the vertical side, and when a fixing block of the i-shaped structure is fabricated on the vertical side, if the glue solution is directly injected into the vertical side by using the needle tube, a large amount of glue solution is directly dropped by gravity when injected into the vertical side due to the adhesiveness between the glue solutions, and does not adhere to the vertical side of the box body. According to the invention, a small amount of glue solution is firstly extruded to one side of the corner to be pasted through the elliptical hole, the glue solution can be attached to the box body due to the adhesiveness of the glue solution, and the glue solution extruded to one side of the corner to be pasted is small in amount, so that the glue solution can not slide down from the box body in a short time, then the front end of the outer cylinder is aligned with one side of the corner to be pasted, the glue solution in the inner cylinder is extruded out, the extruded glue solution can be contacted with the glue solution attached to the box body in advance, under the effect of the adhesiveness of the glue solution, the glue solution extruded from the elliptical hole can be prevented from directly dripping from the inner cylinder to a certain extent, and the glue solution can be dripped even under the effect of the glue solution extruded from the elliptical hole when the amount of the glue solution extruded from the inner cylinder is large. Therefore, the glue solution extruded from the inner cylinder is circularly extruded out and sucked into the inclined table top, so that the glue solution extruded from the inner cylinder can be ensured not to drip. In addition, the inner cylinder is provided with the refrigerating pipe, and in the process of circularly extruding and sucking the glue solution extruded from the inner cylinder into the inclined table top, part of the glue solution is gradually solidified and molded under the refrigerating action of the refrigerating pipe. The glue solution at the small diameter opening of the inclined table surface is contacted with the hot glue solution in the inner cylinder, so that the glue solution at the front end of the large diameter opening is cooled, solidified and formed earlier than the glue solution at the small diameter opening of the inclined table surface, the glue solution at the front end of the large diameter opening is firstly solidified and formed into a circular table-like jelly protruding out of the inclined table surface in the circulating extrusion and suction processes of the glue solution, the jelly cannot fall off from the inclined table surface under the action of the glue solution, a slit channel is formed between the jelly and the inclined table surface which is circular table-like at the moment, the glue solution is continuously circulated and extruded and sucked afterwards, the glue solution is extruded from the slit channel and extruded to the surface of the box body, and a first fixing block with corresponding thickness is formed on the surface of the box body under the further action. In order to ensure that the glue solution is cooled layer by layer along the refrigerating pipe from inside to outside in the sequence from front to back to form a first fixing block, when the second pressure pump circularly extrudes and sucks the glue solution in the inner cylinder, the adopted pressure is gradually reduced so that the position where the glue solution in the inner cylinder is extruded is gradually behind, and the position where the glue solution in the inner cylinder is sucked is gradually behind, so that the smooth formation of the first fixing block on one side of the corner to be attached can be ensured.
In addition, when the aperture of the elliptical hole is small, if more glue solution is extruded from the elliptical hole, the extruded glue solution is easy to drip, but if less glue solution is extruded from the elliptical hole, the glue solution attached to the box body is low in adhesive force to the glue solution extruded from the inner cylinder, and then a fixing block formed on one side of the corner to be attached is small, so that the occasion with high requirement on firmness cannot be met. Therefore, the adjusting cover is designed, according to the firmness requirement, the rotating motor is controlled to drive the adjusting cover to rotate through the L-shaped connecting rod, the relative position between the first elliptical hole and the second elliptical hole is adjusted, the size of the formed glue outlet hole is adjusted, when the glue outlet hole is large, the contact area between glue extruded from the glue outlet hole and the box body is increased, even if a large amount of glue is extruded, the glue does not drip, on the premise that the glue extruded from the glue outlet hole is not dripped, the adhesive force of the large amount of glue to the glue extruded from the inner cylinder is larger, the amount of glue extruded from the inner cylinder is larger, the sectional area of the fixing block can be increased, and the firmness of the I-shaped structure is higher. When going out the jiao kou less, the area of contact between glue solution that extrudes from going out the jiao kou and the box is less, therefore only extrude a small amount of glue solution, just can guarantee that the glue solution can not drip yet, extrude under the prerequisite that the glue solution can not drip from going out the jiao kou, less glue solution is little to the adhesive force of the glue solution of extruding from the inner tube, therefore can follow the glue solution volume of extruding of inner tube also still less, thereby the sectional area of the fixed block of formation is also littleer, this is applicable to the not high occasion of fastness requirement. Therefore, the relative positions of the first elliptical hole on the outer cylinder and the second elliptical hole on the adjusting cover are adjusted by arranging the adjusting cover, so that the glue solution extruded from the glue outlet hole can be prevented from dripping, the glue outlet amount extruded from the glue outlet hole can be adjusted, and the sizes of the two fixed blocks in the I-shaped structure can be adjusted.
After the first fixed block is cooled and formed, controlling the second pressure pump 11 to suck out a corresponding amount of glue solution in the inner cylinder 2 from the inner cylinder 2, thereby adjusting the thickness of the connecting rod in the I-shaped structure. The outer side of the part of the refrigerating pipe 5 in the inner cylinder 2 is wrapped with the isolating layer 51, the isolating layer 51 can reduce the conduction efficiency of cold air conducted by the refrigerating pipe 5, but can not completely isolate the conduction of the cold air, and therefore, the thickness adjustment of the connecting rod cannot be influenced when the first fixing block is manufactured. Because the isolating layer 51 can also conduct part of cold air to the glue solution in the inner cylinder 2, the glue solution surrounding the cooling pipe 5 can be preferentially cooled and formed, when the corresponding amount of glue solution in the inner cylinder is pumped out by using the second pressure pump, part of the glue solution surrounding the cooling pipe 5 circularly is actually cooled and formed, and the sucked-out glue solution is the outermost glue solution of the cooling pipe 5, so that the thickness of the connecting rod can be adjusted, the shape of the connecting rod can be ensured to be regular and circular, the outermost glue solution of the cooling pipe can be sucked out, and the smooth separation of the inner cylinder and the connecting rod can be ensured.
After the connecting rod is cooled and formed, the controller controls the shrinkage rod 6 to shrink until the glue outlet hole in the outer cylinder 1 penetrates out of the other side of the corner to be attached, and then a second fixing block in an I-shaped structure is formed on the other side of the corner to be attached by adopting the same method as the first fixing block. Specifically, the first pressure pump 10 is controlled to extrude the glue solution in the channel to the other side of the corner to be pasted through the glue outlet, the second pressure pump 11 is controlled to press the glue solution into the inner barrel 2 at the same time until the glue solution is extruded to the inclined table top 3, after a corresponding amount of glue solution is extruded to the other side of the corner to be pasted through the glue outlet, the telescopic rod 6 is controlled to contract until the front end of the refrigerating pipe 5 is parallel to the other side of the corner to be pasted, the refrigerating device 12 is controlled to refrigerate, the second pressure pump 11 is further controlled to circularly extrude and suck the glue solution in the inner barrel 2 from the inclined table top 3, after the circulation is carried out for a preset number of times, the second fixed block in the I-shaped structure is cooled and formed on the other side of the corner to be pasted, and therefore the I-shaped structure comprising the first fixed block, the connecting rod and the second fixed block is formed, and corner fitting is carried out on the box body by utilizing the I-shaped structure.
Compared with a light and thin adhesive tape, the adhesive tape has the advantages that the I-shaped structure formed by the adhesive liquid is firmer, the box body is subjected to corner pasting by the I-shaped structure, and the corner pasting effect is better; the invention also solves the problem that the fixing block in the I-shaped structure is not easy to form on the vertical end surface. In addition, the relative positions of the first elliptical hole on the outer cylinder and the second elliptical hole on the adjusting cover are adjusted by arranging the adjusting cover, so that the sizes of the two fixing blocks in the I-shaped structure can be adjusted, and the thickness of the connecting rod in the I-shaped structure can be adjusted by sucking out glue liquid in the inner cylinder after the first fixing block is formed, so that the firmness of the I-shaped structure is adjusted.
In the present embodiment, the rear side of the cooling pipe 5 is connected to the inside of the inner tube 2 via a support rod 52. The support rods 52 may be at least three and arranged in a crossing manner from front to back. The rear end face of the outer cylinder 1 is connected with the inner cylinder of the telescopic rod 6. A first round hole is formed in the non-coincident part of the rear end face of the outer barrel 1 and the rear end of the inner barrel 2, and the first round hole is communicated with a glue solution tank 8 through a first guide pipe 7. And a second round hole is formed in the overlapped part of the side surface of the outer barrel 1 and the rear end of the inner barrel 2, and the second round hole is communicated with a glue solution tank 8 through a second conduit 9. Electric heating wires are arranged in the inner cylinder 2 and a channel between the outer cylinder 1 and the inner cylinder 2, so that colloid substances in the inner cylinder 2 and the channel can be liquefied, and glue solution can be recycled.
