DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Embodiment: A bending device for processing paper straws comprises a workbench 1 arranged on which a conveying member is driven, and two groups of support plates 2 are fixedly mounted on the top surface thereof, wherein the top surface of the support plate 2 is provided with an adjusting groove for adjusting the position of a sliding shell 3, and then fixed, and a distance scale line can be provided on the upper side of the adjusting groove for facilitating accurate adjustment of the required distance, the upper sides of the two groups of support plates 2 are slidably matched with a sliding shell 3, and the sliding shell 3 is connected to the support plate 2 by a fastener 4, wherein the fastener 4 can be provided with bolts and screws. The sliding shell 3 is provided with a plurality of groups of balls 301 on the bottom surface of the sliding shell 3, and the outer surfaces of the balls 301 are slidably matched with the guide grooves provided on the top surface of the supporting plate 2. The balls 301 provided here are convenient for reducing the friction when moving the sliding shell 3, making the movement process more labor-saving. A bending piece 6 is provided on the lower side of the sliding shell 3. The bending piece 6 provided here is used to bend the paper straws. A limiting piece 5 is provided on the left side of the bending piece 6. The limiting piece 5 provided here is used to preliminarily limit the paper straws to be bent.

[0027] Among them, the limiting member 5 includes two groups of limiting plates 501 fixedly installed on the top surface of the workbench 1. The limiting plates 501 arranged here can perform preliminary limiting on the paper straws. The inner walls of the limiting plates 501 are fixedly connected with inflatable rubber pads 502 for fixing paper straws. The inflatable rubber pads 502 arranged here can be inflated and deflated. During the bending action, the paper straws to be bent are stably clamped and fixed, so as to avoid the situation that the creases of the same batch are not uniform due to shaking during the bending process. The inflatable rubber pads 502 are inflated and deflated through the auxiliary parts 7. Through the auxiliary parts 7, the inflatable rubber pads 502 can be inflated and deflated synchronously when the bending member 6 is working, and share a power source with the bending member 6, which is more flexible and convenient;

[0028] Among them, the bending part 6 includes a driving source 601 fixedly installed inside the sliding shell 3. The driving source 601 set here is set as a stepping motor, and the rotating disk 602 is driven to rotate back and forth half a circle by setting a controller and an encoder. The output end of the driving source 601 is fixedly connected to the rotating disk 602, and a fixed rod 603 is fixedly installed on the bottom surface of the rotating disk 602. The bottom surface of the rotating disk 602 rotates to cooperate with the limiting rod 604, and the paper straws are bent by the cooperation of the set fixed rod 603 and the limiting rod 604. Since the position of the limiting rod 604 is fixed, the fixed rod 603 rotates to apply force to the paper straw to bend. The limiting rod 604 is fixedly connected to one side surface of the sliding shell 3 through the connecting rod 605, and is fixed to the sliding shell 3 by setting the limiting rod 604. When the sliding shell 3 is moved to drive the movement, the limiting rod 604 can also move, and the bottom surface of the limiting rod 604 slides with the top surface of the workbench 1;

[0029] Among them, the auxiliary component 7 includes an air cylinder 701 fixedly installed inside the sliding shell 3, and a piston 702 is slidably matched inside the air cylinder 701. The air cylinder 701 cooperates with the piston 702 to inflate and deflate the inflatable rubber pad 502. A push rod 703 is fixedly connected to one side of the piston 702, and a rack 704 is fixedly connected to one end of the push rod 703. The outer surface of the rotating disk 602 is provided with gear teeth that cooperate with the rack 704, and the bottom of the rack 704 is limited by a sliding groove provided on the inner wall of the sliding shell 3. Limiting the rack 704 can make the rack 704 move in the horizontal direction during the rotation of the rotating disk 602, thereby driving the piston 702 to move inside the air cylinder 701. Two sets of connecting rods 705 are fixedly connected to both ends of the rack 704. The two ends on the same side are The outer surface of the connecting rod 705 is slidably matched with a sliding block 706, and one end of the sliding block 706 is meshed with the gear teeth. When the gear teeth on the rotating disk 602 are meshed with the sliding block 706, the rotating disk 602 continues to rotate the rack 704 to maintain the original position. The outer surface of the connecting rod 705 is sleeved with an elastic member 707. The two ends of the elastic member 707 provided here are respectively fixedly connected to the outer surface of the connecting rod 705 and one side of the sliding block 706, thereby exerting a force on the sliding block 706. One end of the air cylinder 701 is connected to a retractable hose 708. The retractable hose 708 can be matched with the required length when the sliding shell 3 drives the auxiliary member 7 to move. One end of the hose 708 is connected to a connecting pipe 709, and the connecting pipe 709 is connected to the two groups of inflatable rubber pads 502.

[0030] Specifically, in the process of processing and bending paper straws, the paper straws are placed on the upper side of the workbench 1 in sequence, and then moved through the transmission. When the paper straws to be bent are moved to the desired position, the driving source 601 is controlled to drive the rotating disk 602 to rotate. Here, the fixed rod 603 applies force to the paper straws to bend them by cooperating with the limit rod 604. At the same time, in this process, the gear teeth on the rotating disk 602 engage with the rack 704 to drive the rack 704 to move, thereby making the active disk 602 The plug 702 moves to inflate the inflatable rubber pad 502. At the same time, due to the cooperation of the sliding block 706 with the elastic part 707, the rotating disk 602 continues to rotate while the rack 704 does not move, so that the paper straw can be fixed before the bending process is completed. After the bending is completed, the driving source 601 can be controlled to reverse. When the crease position needs to be adjusted, it is only necessary to disassemble the fastener 4 and then move the sliding shell 3 to the desired position, which can drive the bending part 6 to the desired position, and then install the fastener 4 to fix the sliding shell 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
