[0020] In one embodiment, the feeding tooth includes a vertical portion and an outwardly extending extension disposed at the top of the vertical portion.

[0021] The beneficial effects of this application are as follows:

[0022] 1. The folding mechanism of the bag opening machine of this application has a simple and compact overall structure. It only needs to be set below the worktable of the laser bag opening machine and does not occupy the space above the worktable.

[0023] 2. In this application, the X-axis material pushing plate and the Y-axis material pushing plate of the folding mechanism are both controlled by a screw mechanism to move, which is beneficial to adapt to the opening requirements of different sizes of bags.

[0024] 3. After the long side of the bag opening is folded, it can be supported by the X-direction material support plate, and after the short side is folded, it can be supported by the Y-direction material pusher plate.

Similarly, the insert teeth at the front end of the Y-direction material support plate can be inserted into the gap between the push teeth at the front end of the Y-direction material pusher plate, so the Y-direction material support plate can support the short side without interfering with the Y-direction material pusher plate.

[0026] 5. The material-feeding teeth include a vertical part and an outwardly extending part set at the top of the vertical part. This design provides good material-feeding effect on both the long and short sides of the bag opening.

[0027] 6. The X-axis and Y-axis material support plates of this application are both mounted on linear guide rails and directly driven by cylinders. This makes the X-axis and Y-axis material support plates move quickly and sensitively, and the operation is stable and reliable, which is conducive to improving production efficiency.

[0028] 7. The Y-axis material-pushing plate of this application has an independent lifting mechanism at its bottom. After the two X-axis material-pushing plates separate to form a certain space, the two Y-axis material-pushing plates can first enter the first position, located between the two X-axis material-pushing plates, driven by their respective Y-axis screw drive components. Then, driven by the lifting mechanism, they rise without touching the short side of the bag opening. Next, driven by their respective Y-axis screw drive components, they move outwards, pushing the short side of the bag opening to fold it over. Furthermore, at the second position, the Y-axis material-pushing plate is outside the X-axis material-pushing plate. The Y-axis material-pushing plate does not interfere with the movement of the X-axis material-pushing plate. Attached Figure Description

Detailed Implementation

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 3As shown, an embodiment of this application provides a folding mechanism for a bag-opening machine. This folding mechanism includes: a base 101, a first screw drive assembly 102, two X-direction material-pushing plates 103, and a main lifting mechanism 104. The first screw drive assembly 102 is mounted on the base 101, and the two X-direction material-pushing plates 103 are mounted on the first screw drive assembly 102. The two X-direction material-pushing plates 103 move closer or further apart synchronously. The main lifting mechanism 104 is connected to the base 101 and is used to drive the base 101 to rise or fall. A first bracket 109 and a second bracket 110 are respectively connected to both sides of the base 101. A first vertical guide rail 111 and a first lifting mechanism 112 are mounted on the first bracket 109, and a second vertical guide rail 113 and a second lifting mechanism 112 are mounted on the second bracket 110. 14. A first support platform 115 is installed on the first vertical guide rail 111. A first Y-axis lead screw drive assembly 116 is installed on the first support platform 115 and the first support platform 115 is connected to the first lifting mechanism 112. A second support platform 117 is installed on the second vertical guide rail 113. A second Y-axis lead screw drive assembly 118 is installed on the second support platform 117 and the second support platform 117 is connected to the second lifting mechanism 114. A first Y-axis material pusher plate 119 is disposed on the first Y-axis lead screw drive assembly 116, and a second Y-axis material pusher plate 120 is disposed on the second Y-axis lead screw drive assembly 118.

[0042] The first Y-axis material pusher 119 has a first position and a second position. When the first Y-axis material pusher 119 is in the first position, it is located between two separate X-axis material pushers 103. When the first Y-axis material pusher 119 is in the second position, it is located outside the two X-axis material pushers 103. The second Y-axis material pusher 120 has a third position and a fourth position. When the second Y-axis material pusher 120 is in the third position, it is located between two separate X-axis material pushers 103. When the second Y-axis material pusher 120 is in the fourth position, it is located outside the X-axis material pushers 103.

[0043] Specifically, the fabric 300 on the bag opening machine is first laser-cut, and then the long side 310 and short side 320 of the bag opening are pushed downwards by a downward pressing and spreading mechanism. Because the bag opening machine is equipped with limit plates, the long side 310 and short side 320 will be pushed downwards along the limit plates. For example, there are two X-direction limit plates 125 and two Y-direction limit plates 126.

[0044] Next, the folding mechanism described above in this application is used to fold the long side 310 and the short side 320. Specifically, in the initial position, the two X-direction material-pushing plates 103 are close together, and the first Y-direction material-pushing plate 119 and the second Y-direction material-pushing plate are both located outside the X-direction material-pushing plate 103. Then, the main lifting mechanism 104 drives the base 101 to rise, and the base 101 also drives the first bracket 109 and the second bracket 110 to rise, so that the two X-direction material-pushing plates 103, as well as the first Y-direction material-pushing plate 119 and the second Y-direction material-pushing plate, all rise. Then, the two X-direction material-pushing plates 103 are separated from each other under the drive of the first lead screw drive assembly 102, and the two long sides 310 of the bag opening can be folded by the two X-direction material-pushing plates 103. Next, the first Y-axis material pusher plate 119 and the second Y-axis material pusher plate move closer together and between the two X-axis material pusher plates 103. Then, both the first Y-axis material pusher plate 119 and the second Y-axis material pusher plate rise to a predetermined height. Then, both the first Y-axis material pusher plate 119 and the second Y-axis material pusher plate move outward, allowing the two short sides 320 to be folded. This completes the flipping operation of the long side 310 and the short side 320.

[0045] Building upon the above, further, such as Figure 1 and Figure 6 As shown, the upper end of the first Y-axis material pusher plate 119 is provided with several spaced-apart material pusher teeth 1031, the upper end of the second Y-axis material pusher plate is provided with several spaced-apart material pusher teeth 1031, and the upper end of the X-axis material pusher plate 103 is provided with several spaced-apart material pusher teeth 1031. It also includes an X-axis material support plate 128 disposed above the X-axis material pusher plate 103. The X-axis material support plate 128 is mounted on the X-axis linear guide rail 129. The front end of the X-axis material support plate 128 is provided with several spaced-apart insert teeth 1281. The X-axis material support plate 128 is connected to the X-axis cylinder drive assembly 130. Specifically, two X-axis material support plates 128 can be provided, with each X-axis material support plate 128 corresponding to one of the two X-axis material pusher plates 103. Each X-axis material support plate 128 is driven by its own cylinder drive assembly. It also includes a Y-axis material support plate 127 disposed above the Y-axis material pusher plate. The Y-axis material support plate 127 is mounted on the Y-axis linear guide rail 131. The front end of the Y-axis material support plate 127 is provided with several spaced-apart inserts 1271. The Y-axis material support plate 127 is connected to the Y-axis cylinder drive assembly 132. Specifically, two Y-axis material support plates 127 can be provided, and the two Y-axis material pusher plates are configured one-to-one. Each Y-axis material pusher plate is driven by its own cylinder drive assembly.

[0046] When the long side 310 and short side 320 of the bag opening are folded, the X-direction material support plate 128 and the Y-direction material support plate 127 extend under the drive of the cylinder drive assembly. The insertion teeth 1281 at the front end of the X-direction material support plate 128 can be inserted into the gap between the material-pushing teeth 1031 at the front end of the X-direction material-pushing plate 103, and the insertion teeth 1271 at the front end of the Y-direction material support plate 127 can be inserted into the gap between the material-pushing teeth 1031 at the front end of the Y-direction material-pushing plate. In this way, the two long sides 310 are supported by the two X-direction material support plates 128, and the two short sides 320 are supported by the two Y-direction material support plates 127. The long side 310 is clamped between the limiting plate and the X-direction material support plate 128, and the short side 320 is clamped between the limiting plate and the Y-direction material support plate 127.

[0047] Next, the main lifting mechanism 104 descends, and the Y-direction material pusher plate and the X-direction material pusher plate 103 are reset.

[0048] One implementation of the reset process can be as follows: the two Y-axis material pushers move closer together, then the two Y-axis material pushers descend and separate from each other, so that the Y-axis material pushers are located outside the two X-axis material pushers 103. Next, the two X-axis material pushers 103 move closer together.

[0049] In one embodiment, the main lifting mechanism 104 includes a vertically arranged Z-axis lead screw drive assembly 1042. Specifically, the main lifting mechanism 104 can be configured in various ways. For example, the main lifting mechanism 104 includes a main board 1041 and a Z-axis lead screw drive assembly 1042. The main board 1041 is connected to the Z-axis lead screw drive assembly 1042, and four columns 1043 are fixed at the four corners of the main board 1041. The upper ends of the columns 1043 are respectively connected to the base 101. Driving the main board 1041 to lift and lower via the Z-axis lead screw drive assembly 1042 can drive the four columns 1043 to lift and lower the base 101. Furthermore, a guide assembly 1044 can also be provided on the main board 1041. The guide assembly 1044 can consist of a frame and guide columns arranged on the frame.

[0050] In one embodiment, the first lead screw drive assembly 102 includes a first motor and a first lead screw connected to the first motor. Two first sliders are mounted on the first lead screw, and two X-axis material-pushing plates 103 correspond one-to-one with the two first sliders. The X-axis material-pushing plates 103 are connected to their respective first sliders via connecting components. This allows the two X-axis material-pushing plates 103 to be driven to synchronously move closer together or separate from each other. Furthermore, the distance between the two X-axis material-pushing plates 103 can be adjusted as needed to accommodate different opening sizes.

[0051] In one embodiment, the connecting assembly includes a support block 105, a slide rail connecting block 106, and a slider connecting block 107. The support block 105 is connected to the X-direction feeding push plate 103, the slider connecting block 107 is connected to the support block 105, and the slide rail connecting block 106 is also connected to the X-direction slide rail assembly 108 disposed on the base 101. The slider connecting block 107 is connected to the slide rail connecting block 106, and the slider connecting block 107 is also connected to the corresponding first slider. This arrangement facilitates installation and maintenance.

[0052] In one embodiment, the first Y-axis material pusher plate 119 moves synchronously with the second Y-axis material pusher plate. It is understood that the first Y-axis material pusher plate 119 may also not move synchronously with the second Y-axis material pusher plate. Synchronous movement helps save time and improve efficiency.

[0053] In one embodiment, the first Y-axis push plate 119 is connected to the first connecting block 121, and the first connecting block 121 is detachably connected to the second connecting block 122. A plurality of position adjustment holes 124 are provided between the first connecting block 121 and the second connecting block 122. The second connecting block 122 is connected to the third connecting block 123, and the third connecting block 123 is connected to the first Y-axis lead screw drive assembly 116. The aforementioned position adjustment holes 124 facilitate the adjustment of the relative position between the first connecting block 121 and the second connecting block 122, thereby allowing adjustment of the lateral position of the first Y-axis push plate 119.

[0054] Similarly, the second Y-axis pusher plate is connected to the fourth connecting block, the fourth connecting block is detachably connected to the fifth connecting block, a number of position adjustment holes 124 are provided between the fourth connecting block and the fifth connecting block, the fifth connecting block is connected to the sixth connecting block, and the sixth connecting block is connected to the second Y-axis lead screw drive assembly 118.

[0055] In one embodiment, such as Figure 8 As shown, the feeding tooth 1031 includes a vertical portion 1031a and an outwardly extending extension portion 1031b disposed at the top of the vertical portion 1031a.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
