The other layer of the cloth bag can be clamped through the pressing plate 2211 and the upper clamping piece 2221, thereby clamping the cloth bag as a whole and being able to drive the cloth bag to move;

[0032] Furthermore, the flipping abutting mechanism 3 includes a plug-in piece 31 that is horizontally movably arranged. The plug-in piece 31 can maintain the movement in the horizontal direction on the frame 1. By inserting the plug-in piece 31 between the upper clamping piece 2221 and the lower clamping piece 2222 and abutting against the cloth bag, the inside and outside of the cloth bag are flipped.

[0033] In this utility model, the cloth bag clamping mechanism 22 is driven to move by the horizontal driving unit 21 of the moving mechanism 2. The sewn cloth bag is manually sleeved onto the upper clamping unit 221 and the lower clamping unit 222, and then the plug-in piece 31 of the flipping abutting mechanism 3 abuts against the cloth bag, causing the cloth bag to flip between the upper clamping piece 2221 and the lower clamping piece 2222, thereby flipping the inside and outside of the cloth bag. The sewn line can be hidden inside the cloth bag, making the outside of the cloth bag more beautiful. By replacing manual flipping of the cloth bag, the manual work intensity is reduced, and the manual production cost is reduced.

A pressing plate 2211 is fixedly installed at the output end of the first lifting driving unit 2212. The first lifting driving unit 2212 can drive the pressing plate 2211 to lift.

[0036] As a further embodiment provided by the present utility model, as Figure 3 shown in the figure, the lower clamping unit 222 further includes a second lifting driving unit 2223, a mounting bracket 2224, and a third lifting driving unit 2225. The second lifting driving unit 2223 is fixedly installed on the outer wall of one side of the connecting plate 25. The mounting bracket 2224 is fixedly installed at the output end of the second lifting driving unit 2223. One end of the lower clamping piece 2222 is fixedly installed at one end of the mounting bracket 2224, and the lower clamping piece 2222 is perpendicularly arranged with the mounting bracket 2224. The third lifting driving unit 2225 is fixedly installed on the outer wall of one side of the mounting bracket 2224. The upper clamping piece 2221 is fixedly installed at the output end of the third lifting driving unit 2225, and the upper clamping piece 2221 is located above the lower clamping piece 2222.

[0037] Specifically, the first lifting driving unit 2212, the second lifting driving unit 2223, and the third lifting driving unit 2225 can all be conventional mechanical components such as cylinders or linear driving modules.

[0038] Furthermore, as Figure 4 shown in the figure, receiving grooves 12 are symmetrically formed on the outer wall of one side of the support positioning plate 11. A sorting groove 32 is formed on the inserting piece 31. The inserting piece 31 can be embedded into the inside of the receiving groove 12. The number of inserting pieces 31 is two. The flipping abutting mechanism 3 further includes a transverse driving unit 33. The transverse driving unit 33 is fixedly installed on the outer wall of one side of the frame 1.

[0039] The transverse driving unit 33 can be a conventional mechanical component such as a cylinder or a linear driving module.

[0040] As an embodiment provided by the present utility model, asFigure 4 and Figure 5 As shown in Figure 5 , the flipping abutting mechanism 3 further includes an abutting driving unit 34. The abutting driving unit 34 includes a lifting telescopic cylinder 341.A and an abutting piece 342. The lifting telescopic cylinder 341 is fixedly installed on the outer wall of one side of the frame 1, and the abutting piece 342 is fixedly installed at the output end of the lifting telescopic cylinder 341. Abutting parts are symmetrically arranged on the abutting piece 342. The abutting piece 342 can be in abutment with the plug-in piece 31 through movement, so that the plug-in piece 31 rotates by a certain angle, facilitating the insertion of the plug-in piece 31 between the upper clamping piece 2221 and the lower clamping piece 2222.

[0041] The cloth bag pressing mechanism 23 is fixedly installed on the outer wall of one side of the connecting plate 25. Specifically, the cloth bag pressing mechanism 23 includes a lifting unit 231 and a pressing piece 232. The lifting unit 231 is fixedly installed on the outer wall of one side of the connecting plate 25. The pressing piece 232 is specifically an "L" - shaped structure. The pressing piece 232 is fixedly installed on the outer wall of one side of the connecting plate 25. Through - holes are formed on the upper clamping piece 2221, the lower clamping piece 2222 and the pressing plate 2211. The pressing piece 232 can descend through the lifting unit 231 and penetrate through the through - hole to abut against the outer wall of the support positioning plate 11, fixing the bag body on the support positioning plate 11. The lifting unit 231 is a cylinder or a linear actuator.

[0042] Working principle:

[0043] When turning the bag, first, the horizontal driving unit 21 drives the cloth bag clamping mechanism 22 to move. Manually, the sewn bag body is sleeved on the lower clamping piece 2222 and the upper clamping piece 2221 of the cloth bag clamping mechanism 22, and the cloth bag is clamped and moved to the support positioning plate 11 through the pressing plate 2211 and the upper clamping piece 2221.

[0044] After moving the cloth bag to the designated position, the lifting unit 231 drives the pressing piece 232 to fix the cloth bag on the support positioning plate 11.

[0045] Subsequently, the lifting telescopic cylinder 341 drives the abutting piece 342 to move upward, abutting against the plug - in piece 31, so that one end of the plug - in piece 31 rotates by a certain angle.

[0046] At this time, the first lifting driving unit 2212 and the third lifting unit 231 move upward by a certain distance, causing the separation between the upper clamping piece 2221 and the lower clamping piece 2222.

[0047] As Figure 6 and Figure 7As shown, the insertion piece 31 is driven to move by the lateral driving unit 33. When the insertion piece 31 moves and abuts against the bottom of the bag body, the continuous movement of the insertion piece 31 can move the bag body towards the upper clamping piece 2221 and the lower clamping piece 2222, so as to turn the bag body. While the bag body is being turned, since a finishing groove 32 is formed on the outer wall of one side of the insertion piece 31, the edge of the bag body can be turned in the finishing groove 32, and finally the turning of the bag body is completed.

[0048] After the reversal, the lateral driving unit 33 drives the insertion piece 31 to reset, and the upper clamping piece 2221 and the lower clamping piece 2222 are separated. At this time, the operator can take out the turned bag body.

[0049] Those skilled in the art can understand that other similar connection methods can also implement the present utility model. For example, welding, bonding or screwing, etc.

[0050] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
