Description

Technical Field

[0002] In the production process, in order to protect expensive equipment and products, corner wraps are generally used to wrap these equipment or products at various angles. These corner wraps are made of foam material and play a buffering role for the equipment and products to prevent them from being damaged during transportation. Figure 1 As shown, the corner wrap 400 generally includes three surfaces, a bottom surface 401 and wall surfaces 402 arranged on two adjacent sides of the bottom surface 401. The two wall surfaces 402 are interconnected to form an angle body in which the three surfaces are perpendicular to each other. The existing corner wrap 400 is generally directly made of three separate plates spliced ​​and bonded with glue, and the splicing and bonding are completed manually; the processing method is to first punch the plate to form a unit, then trim each unit, and finally bond the edges to each other, and the punching, cutting and pasting are three separate operations. This method has a very low production efficiency and cannot meet the requirements of mass production. In addition, the two adjacent surfaces are not aligned, and the splicing quality is poor; after forming, the splicing line can be seen from the outside, which is not beautiful enough.

[0028] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0029] like Figures 2 to 4 As shown, the corner forming machine 100 of the present invention is suitable for forming a foamed material plate 500 into a corner 300. The material of the foamed material plate 500 in this embodiment is pearl cotton, and other materials with similar properties to pearl cotton can also be used. The corner forming machine 100 includes a hot pressing device and a forming device; the hot pressing device includes a first driving mechanism 1 and a hot pressing mold 2, the output end of the first driving mechanism 1 is connected to the hot pressing mold 2 and drives the hot pressing mold 2 to approach the material plate 500, so as to hot press the material plate 500 to form a template 200 that can be folded into a corner 300; the forming device includes a second driving mechanism 3 and a forming mold 4, the output end of the second driving mechanism 3 drives the template 200 to enter the forming mold 4, so as to form the template 200 into the corner 300.

[0030] like Figure 4 and Figure 6As shown, specifically, the number of the hot pressing dies 2 in this embodiment is multiple, and the multiple hot pressing dies 2 are fixed side by side on a lifting plate 13. The two ends of the lifting plate 13 move up and down in the vertical direction through the guide rods on the frame 5 of the angle forming machine 100. The first driving mechanism 1 is located at the upper end of the frame 5 and drives the lifting plate 13, so that the hot pressing die 2 can be slid up and down. The number of the forming dies 4 is also multiple, and they are arranged one by one with the hot pressing dies 2. The hot pressing die 2 is located above the forming die 4 so that the material plate passes between the hot pressing die 2 and the forming die 4. In this way, the hot pressing die 2 and the forming die 4 can be set at the same station, so that the material plate can complete the hot pressing and forming processes at the same station, which is conducive to simplifying the structure of the equipment and improving the forming efficiency.

[0031] See also Figure 4 , Figure 5 and Figure 7 The hot pressing mold 2 has two mutually perpendicular first hot pressing heads 21 and two mutually perpendicular second hot pressing heads 22, the second hot pressing heads 22 are perpendicular to the adjacent first hot pressing heads 21, a first material storage area 23 is formed between the two first hot pressing heads 21, and a second material storage area 24 is formed between the first hot pressing head 21 and the second hot pressing head 22; the first material storage area 23 and the two second material storage areas 24 are arranged in an L shape; the first hot pressing head 21 has two first hot pressing surfaces 21a intersecting to form an angle of 90 degrees; the second hot pressing head 22 has a second hot pressing surface 22a intersecting with a vertical plane to form an angle of 45 degrees. By setting the first hot pressing head 21 and the second hot pressing head 22, the material sheet can be hot pressed into a template 200 that can be folded into a wrap angle of 300, thereby facilitating the folding and curing of the template 200 in the next process. In this embodiment, the two hot pressing dies 2 are arranged in parallel, that is, the two hot pressing dies 2 are combined together to form a double hot pressing die; the hot pressing die 2 has a heating wire, which can generate heat after being powered on, and the high temperature of the hot pressing die 2 can melt the heating material plate in contact with it. In this embodiment, a Z-shaped blade 25 is arranged on the splicing line between the two hot pressing dies 2, and the blade 25 protrudes from the first hot pressing head 21 and the second hot pressing head 22. Therefore, during hot pressing, the two interconnected templates 200 can be cut off to form two templates 200. This can simplify the structure of the equipment and improve the efficiency of hot pressing. In addition, a cutter 26 is arranged between the two adjacent double hot pressing dies, and the cutter 26 can also cut off the adjacent templates 200 under the heating of the heating wire. Therefore, the size of the material plate in this embodiment is relatively large, so that after passing through this equipment, multiple wrap angles 300 can be formed at one time, thereby improving production efficiency.

[0032] like Figure 6As shown, the first driving mechanism 1 includes a first motor 11, a ball screw 12 and the lifting plate 13, the hot pressing mold 2 is arranged on the lifting plate 13, the lifting plate 13 is slidably arranged on the frame 5 of the angle forming machine 100 and is threadedly connected to the ball screw 12, the ball screw 12 is vertically arranged and connected to the output end of the first motor 11, and the first motor 11 is arranged on the frame 5.

[0033] Please see again Figure 6 and Figure 7 The molding die 4 has a mold cavity 41 that is interlinked at the upper and lower sides. The mold cavity 41 is directly opposite to the first material receiving area 23. In this way, the bottom surface 301 of the corner 300 can be positioned and driven, and the two side surfaces of the corner 300 can be folded freely, ensuring that the two side surfaces can be smoothly folded into the corner 300 when the template 200 enters the molding die 4. Specifically, the second driving mechanism 3 includes a first linear driver 31, an upper pressing block 32, a second linear driver 33 and a lower pressing block 34. The first linear driver 31 is arranged on the frame 5 of the angle forming machine 100 and is located above the forming die 4, and the output end is connected to the upper pressing block 32 through a connecting rod 35; the connecting rod 35 freely passes through the lifting plate 13, so that the upper pressing block 32 is located at the lower side of the lifting plate 13 and can enter and exit the mold cavity 41; the second linear driver 33 is arranged on the frame 5 of the angle forming machine 100 and is located below the forming die 4, and the output end is connected to the lower pressing block 34 through the connecting rod 35, so that the lower pressing block 34 can enter and exit the mold cavity 41. The first linear driver 31 and the second linear driver 33 are motor screw mechanisms.

[0034] For example Figure 1As shown, the angle forming machine 100 also includes a feeding mechanism 6 and a feeding mechanism (not shown in the figure). The feeding mechanism 6 is arranged at the feeding port of the angle forming machine 100 to feed the material plate 500 to the bottom of the hot pressing mold 2. The feeding mechanism 6 includes a motor belt assembly 61, a sliding bracket 62 and a positioning assembly 63 arranged on the sliding bracket 62. The positioning assembly 63 can be connected to or disconnected from the material plate 500. The sliding bracket 62 is slidably arranged on the frame 5 of the angle forming machine 100. The motor belt assembly 61 has a motor and a belt driven by the motor. The belt is connected to the sliding bracket 62 to drive the sliding bracket 62 to move step by step along the feeding direction. The positioning assembly 63 is a cylinder and a pin. The cylinder is fixed on the sliding bracket 62. The pin is fixed to the output end of the cylinder and is telescopic downward. When the material plate 500 is driven forward, the insertion pin moves downward and is inserted into the material plate 500 and moves with the sliding bracket 62 to drag the material plate 500 forward. Before the sliding bracket 62 is reset, the insertion pin retracts upward and detaches from the material plate 500 to achieve return. The unloading mechanism is located at the lower side of the forming die 4 to unload the formed corner 300. The unloading mechanism can be a fan, which uses the wind blown by the fan to bring out the corner 300 and then collect and transport it away.

[0035] like Figure 2 , Figure 3 and Fig. 9 As shown, a wrap angle forming method comprises the following steps:

[0036] Step S1, using a hot pressing mold 2 to hot press the foaming material board 500 to form a template 200 with an integrated structure, so that the template 200 is an L-shaped structure and has a bottom surface 201 and two wall surfaces 202 connected to each other, and a right-angle groove 203 is formed between two adjacent surfaces, and the outer sides of the two wall surfaces 202 form a 45-degree inclined surface 204;

[0037] Step S2 , when the materials on the right-angle groove and the inclined surface are in a molten state, the template 200 is pressed into the mold cavity 41 of the forming mold 4 , so that the wall surface 302 is folded and fixed vertically to the bottom surface 301 .

[0038] Combining the above and Figure 7 and Figure 8 The working principle of the corner forming machine 100 of the present invention is described in detail below:

[0039] During operation, the material sheet is placed at the feed port of the feeding mechanism 6, and the cylinder is started to drive the pin to insert into the material sheet; then the motor is started to drive the belt to operate, so that the sliding bracket 62 slides forward, and then drives the material sheet to move forward, and the moving distance is the length of a template 200 that can be folded into a wrap angle 300, so that the material sheet enters between the hot pressing mold 2 and the forming mold 4 from the feed port. At this time, the lower pressing block 34 is located at the upper end of the mold cavity 41 and is flush with the surface of the forming mold 4. Afterwards, the first linear drive 31 drives the upper pressing block 32 to move downward to press the material sheet, and at this time, the material sheet is clamped by the upper pressing block 32 and the lower pressing block 34. Then, the first motor 11 is started to drive the lifting plate 13 to move downward, and the lifting plate 13 drives the hot pressing mold 2 to press downward on the material plate. Since the hot pressing mold 2 is in a high temperature state, the part in contact with the material plate can be melted, that is, the first hot pressing head 21 is used to press out a right angle groove 203, and the second hot pressing head 22 is used to press out a second hot pressing surface 22a at an angle of 45 degrees; at the same time, the cutter 26 and the blade 25 cut the material plate into a single L-shaped template 200, and the two first hot pressing heads 21 divide the single template 200 into a bottom surface 201 and two wall surfaces 202 that can be folded into a wrap angle 300. At this time, the material of the side wall of the right angle groove 203 of the template 200 is still in a molten state, and the second linear drive 33 and the first linear drive 31 are started at the same time to drive the upper pressing block 32 and the lower pressing block 34 to clamp the template 200 and move downward at the same time, so that the template 200 passes through the mold cavity 41. When the template 200 enters the mold cavity 41, the two wall surfaces 202 are folded upward under the guidance of the mold cavity 41 and are perpendicular to the bottom surface 201. The two side walls of the right-angle groove are merged and folded along the center line, and the molten materials of the two side walls are bonded and solidified to fix the bottom surface 201 and the wall surfaces 202, and then the corner 300 can be formed. When the corner 300 is sent out from the bottom of the mold cavity 41, the fan blows the corner 300 out. Through the above, the corner 300 can be formed once, and the next corner 300 forming operation can be carried out by simply resetting the above mechanisms.

[0040] Compared with the prior art, the present invention sets a hot pressing mold 2 and uses a first driving mechanism 1 to drive the hot pressing mold 2 to hot press the foamed material sheet, so that the foamed material sheet forms a template 200 that can be folded into a corner 300, and the template 200 has a folding groove and the foaming material in the folding groove is in a molten state; and then a forming mold 4 is set, and the second driving mechanism 3 is used to drive the template 200 to enter the forming mold 4, so that the template 200 is folded along the folding groove and the molten material is solidified to form a corner 300. Therefore, the present invention can perform three-in-one continuous operations of punching, trimming and pasting of the foamed material sheet, so that the corner product can be formed at one time, thereby realizing rapid forming, and the entire equipment is automatically produced without manual operation, and the production efficiency is high. Moreover, since the surfaces of the hot-pressed template 200 are still in a connected state, it only needs to be folded along the hot-pressed folding groove, so that the outer side of the folded corner 300 is a complete surface, avoiding the situation that the surfaces are not aligned after folding, and there will be no splicing line, the splicing quality is good, and the appearance is very beautiful. In addition, since the hot pressing molds 2 of the present invention are arranged in an array, multiple side-by-side templates 200 can be hot pressed out of the foaming material board at one time, so the edge material of the foaming material board can be effectively utilized, resulting in less waste material, improving material utilization and saving material.

[0041] The present invention can not only process corner wrapping, but also process packaging boxes. For packaging boxes made of foamed materials, they can be processed by replacing the hot pressing mold and molding film corresponding to the packaging box. It is also done by hot pressing the foamed material into a template that can be folded into a packaging box, so that the material of the connecting edge of the template is in a molten state, and then the template is folded and formed by the molding film and connected to the shape of the packaging box. The various connecting edges are connected and solidified in the molding mold, and finally the packaging box can be processed. The present invention can produce a variety of folding packaging boxes, such as lidless packaging boxes, packaging boxes with flip covers, cylindrical paper boxes, etc., and is not limited to processing only corner wrapping products. Any packaging box products or corner wrapping products similar to the above are equivalent replacements and are within the protection scope of this application.

[0042] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
