Description

Technical Field

[0001] This utility model relates to the field of pocket processing equipment technology, and in particular to a folding bag assembly for a bag opening machine. Background Technology

[0002] In the garment manufacturing process, pocket opening machines are an essential auxiliary processing machine. They are mainly used to create pockets in specific locations on the garment to facilitate carrying small items such as mobile phones and wallets. The current practice is to process the pocket opening and the pocket lip separately first, and then sew the pocket lip onto the pocket opening to complete the pocket opening.

[0003] Furthermore, during bag opening processing, the bag opening needs to be cut and folded. The cut bag opening is then folded inwards through the material window of the outer pressing frame using a folding knife to form a flange. Currently, when folding bag openings of different sizes, the folding knife of the bag folding assembly often needs to be adjusted by turning screws according to the actual size of the bag opening. If a longer bag opening needs to be folded, the installation position of the drive cylinders of the left and right folding knives is adjusted to increase the left and right stroke of the folding knives, thus adapting to the use of folding bags with longer openings.

[0004] Since the folding knife and the driving cylinder that drives the folding knife to fold the bag are generally installed upside down (see Chinese Utility Model Patent No. ZL202020675344.3: A bag opening folding mechanism for garment bag opening processing), this increases the difficulty of adjusting and debugging the folding knife, making the adjustment operation of the folding knife more inconvenient, and thus seriously affecting the efficiency of pocket folding processing. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a bag folding component for a bag opening machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bag-folding assembly for a bag-opening machine includes a fixed base suspended on a processing station. A mounting plate and left and right folding blades are vertically mounted on the fixed base. A drive motor and a rack that meshes with the drive motor are mounted on the mounting plate. The rack drives the left and right folding blades to move forward and backward. A rack and a drive motor that meshes with the left and right folding blades are mounted on the left and right folding blades. The drive motor drives the left and right folding blades to move laterally.

[0008] Preferably, the mounting plate is slidably provided with front and rear folding blade slide plates, and there are two front and rear folding blade slide plates and rack one, which are respectively connected to the front folding blade and the rear folding blade of the front and rear folding blades.

[0009] Preferably, the left and right folding blade plates are slidably provided with left and right folding blade slide plates for mounting the left and right folding blades and a motor slide plate for mounting the second drive motor, and the left and right folding blade slide plates are provided with a transverse cylinder connecting the motor slide plate.

[0010] Preferably, the left and right folding blade slide plates are equipped with lifting cylinders, and the left and right folding blades are connected to the output end of the lifting cylinders.

[0011] Preferably, the mounting plate is disposed on the lifting plate, and the fixed base is provided with a servo motor, the lead screw of the servo motor driving the lifting plate to move up and down.

[0012] The beneficial effects of this utility model are:

[0013] 1. A drive motor and a rack are installed on the mounting plate to drive the front and rear folding blades to move forward and backward. A rack and a drive motor are installed on the left and right folding blade plates to drive the left and right folding blades to move laterally. By electrically adjusting the driving stroke of the drive motors, the folding stroke of the front and rear folding blades and the left and right folding blades can be adjusted. Compared with the existing method of adjusting by turning screws, the folding stroke adjustment of this utility model is more convenient and efficient, which improves the folding efficiency and reduces the difficulty of folding adjustment.

[0014] 2. By installing a horizontal cylinder connected to the motor slide plate on the left and right folding blade slide plates, and fixing the second drive motor on the motor slide plate, the second drive motor can drive the left and right cutting edges of the left and right folding blades near the bag opening to move. The horizontal cylinder drives the left and right folding blades to perform rapid bag folding and retraction actions. The horizontal cylinder and the second drive motor work together to improve the speed of bag folding and retraction of the left and right folding blades. While ensuring the bag folding effect, it avoids the left and right folding blades pulling out the folded edge of the bag when retracting, so as to make the bag folding operation more reliable.

[0022] Example 1:

[0023] like Figures 1-4 As shown, this embodiment discloses a bag-folding assembly for a bag-opening machine, including a fixed base 1 suspended on a processing station. A mounting plate 2 and left and right folding blades 3 are raised and lowered on the fixed base 1. Specifically, the mounting plate 2 is mounted on a lifting plate 13, which is slidably mounted on the side wall of the fixed base 1. The mounting plate 2 and the left and right folding blades 3 move up and down synchronously with the lifting plate 13. A servo motor 11 is provided on the fixed base 1. The lead screw 12 of the servo motor 11 drives the lifting plate 13 to move up and down. Thus, the servo motor 11 and the lead screw 12 cooperate to precisely control the raising and lowering of the mounting plate 2 and the left and right folding blades 3 on the lifting plate 13, so as to realize the raising and lowering action of the front and rear folding blades 22 on the mounting plate 2 and the left and right folding blades 34 on the left and right folding blades 3.

[0024] The mounting plate 2 is provided with a drive motor 23 and a rack 24 that meshes with the drive motor 23. The gear on the drive motor 23 meshes with the rack 24. The rack 24 drives the front and rear folding blades 22 to move back and forth. Specifically, the mounting plate 2 is slidably provided with a front and rear folding blade slide plate 21. The front and rear folding blade slide plate 21 is slidably provided on the mounting plate 2. The rack 24 is fixed to the front and rear folding blade slide plate 21. The drive motor 23 drives the front and rear folding blade slide plate 21 to move back and forth through the rack 24.

[0025] Furthermore, there are two front and rear folding blade slide plates 21 and racks 24, which are respectively connected one-to-one to the front and rear folding blades of the front and rear folding blades 22. That is, one rack is connected to one front and rear folding blade slide plate 21 and the front folding blade, and the other rack is connected to another front and rear folding blade slide plate 21 and the rear folding blade, so as to drive the front and rear folding blades to move the bag folding position through the drive motor 23.

[0026] The left and right folding blade plates 3 are provided with a rack 2 37 and a drive motor 2 36 that meshes with the rack 2 37. The gear on the drive motor 2 36 meshes with the rack 2 37. The drive motor 2 36 drives the left and right folding blades 34 to move laterally. Specifically, the left and right folding blade plates 31 for mounting the left and right folding blades 34 are slidably provided on the left and right folding blade plates 3. The drive motor 2 36 drives the left and right folding blades of the left and right folding blades 34 to move left and right through the left and right folding blade plates 31.

[0027] By setting a drive motor 23 and a rack 24 on the mounting plate 2 to drive the front and rear folding blades 22 to move forward and backward, and setting a rack 37 and a drive motor 36 on the left and right folding blade plates 3 to drive the left and right folding blades 34 to move laterally, this embodiment can adjust the folding stroke of the front and rear folding blades 22 and the left and right folding blades 34 by electrically adjusting the drive stroke of the drive motor 23 and the drive motor 36 (by setting drive stroke parameters to control the drive stroke of the motor, which is prior art and will not be described in detail here). Compared with the existing method of adjusting by turning screws, the folding stroke adjustment of this embodiment is more convenient and efficient, thereby improving the folding efficiency and reducing the difficulty of folding adjustment.

[0028] Example 2:

[0029] This embodiment also discloses a bag-folding assembly for a bag-opening machine. The difference between this embodiment and embodiment 1 is that a motor slide plate 35 for mounting a second drive motor 36 is slidably provided on the left and right folding blade plates 3. In embodiment 1, there can be one second drive motor 36, which cooperates with two meshing racks 37 to drive the left and right folding blades of the left and right folding blade plates 3 to fold the bag and move them respectively. However, in this embodiment, there are two second drive motors 36.

[0030] Specifically, the second rack 37 is fixed on the left and right folding blade plates 3, and the second drive motor 36 is fixedly installed on the motor slide plate 35. The second drive motor 36 cooperates with the second rack 37 that meshes with it to drive the motor slide plate 35 to slide laterally along the left and right folding blade plates 3.

[0031] Furthermore, the left and right folding blade slide plates 31 are provided with two transverse cylinders 32 that are connected to the motor slide plate 35. The transverse cylinders 32 are arranged in a one-to-one correspondence with the motor slide plate 35 and the drive motor 36. The output end of the transverse cylinder 32 is connected to the motor slide plate 35, and the transverse cylinder 32 is fixedly installed on the corresponding left and right folding blade slide plates 31. Thus, the motor slide plate 35 drives the left and right folding blade slide plates 31 to move laterally synchronously through the transverse cylinders 32.

[0032] Specifically, by installing a transverse cylinder 32 connected to a motor slide plate 35 on the left and right folding blade slide plates 31, and fixing a second drive motor 36 to the motor slide plate 25, the second drive motor 36 can drive the left and right folding blade slide plates 31 and the left and right folding blades 34 to move their left and right cutting edges near the bag opening. The transverse cylinder 32 drives the left and right folding blades 34 to perform rapid bag folding and retraction actions. This combination of the transverse cylinder 32 and the second drive motor 36 increases the speed of bag folding and retraction of the left and right folding blades 34, ensuring the bag folding effect while preventing the left and right folding blades 34 from pulling out the folded edge of the bag during retraction, thus making the bag folding operation of this embodiment more reliable.

[0033] Example 3:

[0034] This embodiment also discloses a bag folding component of a bag opening machine. The difference between this embodiment and Embodiment 1 is that a lifting cylinder 33 is provided on the left and right folding blade slide plate 31, and the left and right folding blades 34 are connected to the output end of the lifting cylinder 33 so that the left and right folding blades 34 are driven to move up and down through the lifting cylinder 33. In this embodiment, the left and right folding blades 34 are located above the front and rear folding blades 22.

[0035] In Embodiment 1, the front folding blade, rear folding blade, left folding blade, and right folding blade together form a rectangular outline, and the left folding blade and right folding blade are positioned between the front folding blade and the rear folding blade. That is, the length of the left folding blade and right folding blade in Embodiment 1 must be less than or equal to the distance between the front folding blade and the rear folding blade, thereby limiting the contact area between the left folding blade and the left folding blade and the left and right folding edges of the pocket when folding the bag.

[0036] In this embodiment, the left and right folding blades are positioned above the front and rear folding blades. That is, after the front and rear folding blades move back and forth to fold the front and rear edges of the pocket, the left and right folding blades can move downwards and then to the left and right sides to fold the left and right edges of the pocket. At this time, the length of the left and right folding blades can be slightly smaller than the distance between the front and rear folding blades after they have folded the pocket. This allows the longer left and right folding blades to better contact and fold the left and right edges of the pocket, thereby improving the folding effect on the pocket opening.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
