[0050] The push block 4321 is limited in the inner cavity of the sewing platform 4311, and the left side of the push block 4321 is connected and fixed to the right end of the transmission shaft 414, and the right end of the push block 4321 is slidably matched with the buffer groove 43122 in its length direction; the slider 4323 is connected to the outer surface of the push block 4321 through the connecting rod 4322, and the connecting rod 4322, the push block 4321 and the slider 4323 are all connected by hinges.

[0054] Preferably, the outer diameter of the cylinder formed by the arc block 4324 is the same as the inner diameter of the bag head.

[0055] The working principle of this embodiment is: the present invention provides an automatic device for sewing ultra-clean filter bag heads, specifically Figure 1With the orientation as a reference, when the present invention is in use, the bag head of the filter bag can be first put on the arc block 4324, and then the servo cylinder 412 can be started. The piston rod of the servo cylinder 412 drives the transmission shaft 414 to extend, thereby driving the push block 4321 to move to the right. Since the two ends of the connecting rod 4322 are respectively connected to the push block 4321 and the slider 4323 by hinges, the push block 4321 moves and pushes the slider 4323 to slide along the second slide groove 43123, thereby each arc block 4324 can be pushed to form a structure with a cylindrical outer surface, thereby supporting the bag head, so that the bag head can be fixed. After fixing, the servo cylinder 412 is closed. Further, the rotating motor 421 can be started, and the output shaft of the rotating motor 421 drives the synchronous wheel A422 to rotate. Due to the friction transmission between the transmission belt 423 and the synchronous wheel A422 and the synchronous wheel B424, when the synchronous wheel A422 rotates, the transmission belt 423 can drive the synchronous wheel B424 to rotate, thereby driving the bearing sleeve 415 to rotate. Moreover, due to the sliding cooperation between the first slide groove 4141 and the block, the block not only slides with the first slide groove 4141 in its length direction, but also plays a role of limiting in its diameter direction. Moreover, since the transmission shaft 414 is connected to the piston rod of the servo cylinder 412 through a flexible joint, the bearing sleeve 415 can drive the transmission shaft 414 to rotate while rotating. The rotation of the transmission shaft 414 drives the locking mechanism 43 to rotate as a whole, thereby realizing the rotation of the bag head sleeved on the arc block 4324. Then, the sewing machine head 5 is started, and the arc block 4324 drives the bag head to rotate automatically, thereby realizing automatic sewing of the bag head of the filter bag.

[0056] Compared with the prior art, the present invention has the following advantages: First, the present invention realizes the automatic rotation and sewing of the filter bag head to replace the manual sewing work, which greatly saves manpower and improves the sewing efficiency of the filter bag head; the present invention uses the telescopic component 41 to cooperate with the locking mechanism 43 to support and fix the filter bag head through the setting of the sewing mechanism 4, and the present invention also uses the rotating component 42 to drive the output shaft of the telescopic component 41 to rotate, and then the entire locking mechanism 43 rotates, so as to realize the automatic rotation and sewing of the filter bag head. Second, by using the sliding cooperation between the first slide groove 4141 and the card block, the card block not only slides with the first slide groove 4141 in its length direction, but also plays a role of limiting in its diameter direction, so that the bearing sleeve 415 can drive the transmission shaft 414 to rotate while rotating. Third, by setting the arc groove, while supporting the sewing platform 4311, it can also ensure that the rotation of the supporting sewing platform is not blocked. Fourthly, the arc block 4324 is in a closed state before work. At this time, the bag head can be put on the arc block, and then the arc block is started. The arc block is fully expanded and has a cylindrical shape on the outside. Since the outer diameter of the expanded arc block is the same as the inner diameter of the bag head, the bag head can be supported and fixed.

[0057] Embodiment 2

[0058] like Figure 1 , 15 As shown, in this embodiment, after the bag head raw materials are sewn, the unloading assembly 3 can be used to directly put the finished bag head into the finished product storage box 6 without manual operation. The unloading assembly 3 also includes a support device 32, the left end of the support plate 31 is hinged to the middle of the vertical support seat 21; one end of the telescopic device 32 is hinged to the lower end of the vertical support seat 21, and the other end is hinged to the lower surface of the support plate 31; the support device 32 includes two groups of hydraulic telescopic rods with the same structure, the lower end of the hydraulic telescopic rod is connected to the lower end of the vertical support seat 21 through a hinge, and the upper end of the hydraulic telescopic rod is connected to the lower surface of the support plate 31 through a hinge.

[0059] When the present invention is used, Figure 1-15 As shown, the filter bag head can be put on the arc block 4324 first, and then the servo cylinder 412 can be started. The piston rod of the servo cylinder 412 drives the transmission shaft 414 to extend, thereby driving the push block 4321 to move to the right. Since the two ends of the connecting rod 4322 are respectively connected to the push block 4321 and the slider 4323 by hinges, the push block 4321 moves and pushes the slider 4323 to slide along the second slide groove 43123, thereby each arc block 4324 can be pushed to form a structure with a cylindrical outer surface, thereby supporting the bag head, thereby fixing the bag head. After fixing, the servo cylinder 412 can be closed. Further, the rotating motor 421 can be started, and the output shaft of the rotating motor 421 drives the synchronous wheel A422 to rotate. Due to the friction transmission between the transmission belt 423 and the synchronous wheel A422 and the synchronous wheel B424, when the synchronous wheel A422 rotates, the transmission belt 423 can drive the synchronous wheel B424 to rotate, thereby driving the bearing sleeve 415 to rotate. Moreover, due to the sliding cooperation between the first slide groove 4141 and the block, the block not only slides with the first slide groove 4141 in its length direction, but also plays a role of limiting in its diameter direction. Moreover, since the transmission shaft 414 is connected to the piston rod of the servo cylinder 412 through a flexible joint, the bearing sleeve 415 can drive the transmission shaft 414 to rotate while rotating. The rotation of the transmission shaft 414 drives the locking mechanism 43 to rotate as a whole, thereby realizing the rotation of the bag head sleeved on the arc block 4324. Then, the sewing machine head 5 is started, and the arc block 4324 drives the bag head to rotate automatically, thereby realizing automatic sewing of the bag head of the filter bag. After the bag head of the filter bag is sewn, the hydraulic telescopic rod can be directly started to retract. Since the support plate 31 and the vertical support seat 21 are hinged, the hydraulic telescopic rod will drive the support plate 31 to rotate while contracting. Due to gravity, the bag head will automatically fall into the finished product storage box 6 without manual operation, which greatly saves manpower.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
