DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0028] To better understand this utility model, the following is in conjunction with... Figures 1-10 This invention provides a detailed description of an edge template adjustment device.

[0029] Example 1:

[0030] like Figures 1-6 As shown, an edge-fitting template adjustment device includes: an inner fixing plate 100, an inner forming plate 200, an outer fixing plate 300, a widening plate 400, and an outer forming plate 500. The inner forming plate 200 is installed on the inner fixing plate 100. Two outer fixing plates 300, two widening plates 400, and two outer forming plates 500 are provided. The two widening plates 400 are detachably installed on the two outer fixing plates 300 respectively. The two outer forming plates 500 are detachably installed on the two widening plates 400 near the end of the inner forming plate 200 respectively. The outer forming plate 500 and the inner forming plate 200 are arranged parallel to each other, and the outer forming plate 500 is located below the inner forming plate 200. The outer forming plate 500 and the inner forming plate 200 cooperate to fit the edge of the bag body 900.

[0031] It should be noted that during the insertion process, the inner forming plate 200 marks the first fold line 910 and the second fold line 920 on the bag body 900, and the outer forming plate 500 marks the first concave line 930 and the second concave line 940 on the bag body 900, dividing the bag body 900 into five parts connected in sequence: the first insertion surface 950, the second insertion surface 960, the side surface 970, the third insertion surface 980, and the sealing surface 990. The side surface 970 is attached to the upper surface of the inner forming plate 200, the second insertion surface 960 and the third insertion surface 980 are located between the inner forming plate 200 and the outer forming plate 500, and the first insertion surface 950 and the sealing surface 990 are located below the outer forming plate 500.

[0032] In the embodiment, the outer forming plate 500 is provided with an inclined edge 510 which is inclined towards the direction of the inner forming plate 200 along the conveying direction of the bag body 900. In the edge insertion process, the bag body 900 can be guided by the inclined edge 510, and the edge insertion process is gradually completed, and the edge insertion effect is better. The two inner side fixed plates 100 are provided with inclined surfaces 110 on the sides away from each other. The inclined surfaces 110 are inclined towards the inner side along the conveying direction of the bag body 900. By arranging the inclined surfaces 110, the frictional resistance of the bag body 900 from the inner side fixed plate 100 is reduced during the conveying process, which is beneficial to improve the conveying speed of the bag body 900, thereby improving the edge insertion efficiency.

[0033] By using the edge insertion template adjusting device, the widening plate 400 is arranged, and the packaging surface 990 is not hindered by the outer side fixed plate 300 during the edge insertion process of the bag body 900 in the assembly line. The interference between the packaging surface 990 and the outer side fixed plate 300 is avoided, the bag body 900 can be continuously inserted stably, and the edge insertion efficiency of the bag body 900 is improved.

[0034] Embodiment 2:

[0035] As an optimization of embodiment 1, as shown in Figure 5 The widening plate 400 includes a first mounting plate 410, an intermediate connecting plate 420 and a second mounting plate 430 which are connected in sequence. A plurality of first threaded holes 310 are formed in the outer side fixed plate 300. The first mounting plate 410 is provided with through holes 411 which are matched with the plurality of first threaded holes 310. The first mounting plate 410 is fixed on the outer side fixed plate 300 by screws. A plurality of second threaded holes 431 are formed in the second mounting plate 430. The outer forming plate 500 is provided with first straight grooves 520 which are matched with the plurality of second threaded holes 431. The outer forming plate 500 is fixed on the second mounting plate 430 by screws.

[0036] It should be noted that the screws (not shown in the figure) are arranged in the first threaded holes 310 and the through holes 411 to fix the first mounting plate 410 on the outer side fixed plate 300. The screws (not shown in the figure) are arranged in the second threaded holes 431 and the first straight grooves 520 to fix the outer forming plate 500 on the second mounting plate 430 by the screws. The outer forming plate 500 can move along the length direction of the first straight grooves 520 by loosening the screws, so as to adjust the edge insertion depth of the outer forming plate 500, and the adjustment is convenient.

[0037] Embodiment 3:

[0038] As an optimization of embodiment 2, as shown in Figure 5As shown, the second threaded hole 431 is arranged in one-to-one correspondence with the through hole 411, the width of the first straight slot 520 is the same as the inner diameter of the through hole 411, and the surface of the first mounting plate 410 attached to the outer side fixing plate 300 and the surface of the second mounting plate 430 attached to the outer forming plate 500 are flush.

[0039] It should be noted that when the size of the outer forming plate 500 meets the requirements and it can be ensured that the packaging surface 990 does not interfere with the outer side fixing plate 300, the widened plate 400 can not be installed, and the outer forming plate 500 can be fixed on the outer side fixing plate 300 by screws. At this time, the screws are arranged in the first threaded hole 310 and the first straight slot 520, and by loosening the screws, the outer forming plate 500 can still move along the length direction of the first straight slot 520, so as to adjust the depth of the inserted edge of the outer forming plate 500.

[0040] When the widened plate 400 needs to be installed, different widths of the widened plate 400 can be selected for installation according to the width requirements of the four-edge sealed packaging bag. On the premise of ensuring that the packaging surface 990 does not interfere with the outer side fixing plate 300, selecting a widened plate 400 with a relatively small width is beneficial to save costs, and when a bag body 900 with a greater width requirement needs to be inserted, only the appropriate widened plate 400 needs to be replaced, and the adjustment is more convenient.

[0041] In this embodiment, the bottom surface of the first mounting plate 410 is attached to the top surface of the outer side fixing plate 300, the top surface of the second mounting plate 430 is attached to the bottom surface of the outer forming plate 500, and the bottom surface of the first mounting plate 410 is flush with the top surface of the second mounting plate 430.

[0044] It should be noted that the spacing between the outer edges of the two inner forming plates 200 is the width of the four-edge sealed packaging bag after the bag body 900 is manufactured. By adjusting the spacing between the two inner side fixing plates 100, the spacing between the two inner forming plates 200 can be adjusted to facilitate the manufacture of four-edge sealed packaging bags with different width requirements.

The frictional resistance received by the bag body 900 during transmission is reduced, which is beneficial to improve the transmission efficiency of the bag body 900, and further improve the efficiency of the bag body 900 for edge insertion.

[0048] In the embodiment, the two guide wheels 610 are respectively installed on the inner side fixed plate 100 through two connecting members 620. The connecting member 620 is provided with a second straight slot 621, and the length direction of the second straight slot 621 is perpendicular to the length direction of the inner forming plate 200. The connecting member 620 is installed on the inner side fixed plate 100 through a fastening bolt (not shown in the figure), the fastening bolt is arranged in the second straight slot 621, and the fastening bolt is threadedly connected with the inner side fixed plate 100.
