Description

Technical Field

[0001] The present invention relates to the technical field of bag production, and more specifically, to a production device for bag pull rods. Background Art

[0002] Luggage trolleys are an essential part of a suitcase, and are mainly used by users to pull by hand. The materials of trolleys are mainly divided into full aluminum and aluminum alloy. Alloy trolleys are widely used, mainly because they are light, strong, not easy to deform, and will not rust. The cost is relatively high, and the trolley material is the most used material on high-end luggage.

[0003] When processing luggage trolleys, a pipe cutting machine is required. When using existing pipe cutting machines, a longer pipe to be cut is usually placed in the groove of the processing table. This will cause the rod to be offset during cutting, making it inconvenient for workers to cut and reducing the stability and precision of the pipe cutting machine. At the same time, the existing pipe cutting machine cannot realize automatic loading of the pipe to be cut. After each section of cutting is completed, it needs to be manually repositioned, which is cumbersome to operate and reduces the production efficiency of luggage trolleys. Summary of the invention

[0046] A cutting fluid storage box 72 is fixedly installed on the side of the collecting box 19; a vertical plate 73 is fixed on the top of the cutting fluid storage box 72; a piston cylinder 74 is fixed through the side of the vertical plate 73; a push rod 84 is fixed on the side of the second extension plate 75; a first pressure sensor 85 is fixedly installed on the side of the piston cylinder 74; a support plate 86 is fixed on the side of the U-shaped table 11; a baffle 87 is fixed on the side of the support plate 86; a second pressure sensor 88 is fixed on the end of the baffle 87; a controller 89 is fixedly installed on the top of the cutting fluid storage box 72; the input end of the controller 89 is electrically connected to the first pressure sensor 85 and the second pressure sensor 88, and its output end is electrically connected to the drive motor 39, the servo motor 23, and the cutting motor 70, respectively.

[0047] Working principle of the second embodiment:

[0048] In the initial state, Fig.12As shown, the fixed ring 51 is controlled to rotate so that the curved guide plate 52 on the inner peripheral side of the fixed ring 51 is placed above the second ball head 60. The second ball head 60 slides downward under the pressure of the curved guide plate 52, thereby driving the guide part 57 to slide down along the guide rod 13 as a whole. The corresponding second return spring 56 is stretched, and the bottom surface of the straight guide plate 57 on the guide part 57 is pressed on the third ball head 66. At this time, the corresponding third return spring 64 is stretched, and the cutting blade 71 is placed above the pipe 5 to be cut, and the two are not in contact. In this state, the first ball head 31 on the U-shaped conveying platform 3 is separated from the first cam 41, and the first cam 4 1 is vertically upward, and under the elastic force of the corresponding first return spring 33, the first ball head 31 is driven to press against the outer peripheral side of the rotating tube 35, and the corresponding second ball head 32 is away from the pipe 5 to be cut; and the corresponding first ball head 31 on the slide plate 6 is squeezed by the second cam 49 and slides downward, and the corresponding first return spring 33 is compressed, so that the corresponding second ball head 32 presses the pipe 5 to be cut into the first groove 7 on the slide plate 6, so that the sliding part 4 clamps the pipe 5 to be cut, which is convenient for subsequent stable cutting; in this state, the pipe 5 to be cut can move with the movement of the sliding part 4, so that the automatic feeding of the pipe 5 to be cut is realized.

[0049] Cutting process, such as Fig.13 As shown, the servo motor 23 is controlled to start, driving the screw 22 to rotate, thereby driving the sliding part 4 together with the clamped pipe 5 to be cut to slide synchronously along the U-shaped conveying platform 3 toward the direction close to the supporting platform 2, thereby driving the third ball head 66 to slide from the bottom surface of the straight guide plate 57 into the bottom surface of the inclined guide plate 58. Under the guiding force of the inclined guide plate 58, the third ball head 66 descends during the sliding process until the cutting blade 71 touches the pipe 5 to be cut that slides synchronously with it, and the cutting blade 71 gradually descends to cut the pipe 5 to be cut. During this process, one end of the pipe 5 to be cut passes through the first guide ring 25 and enters the second groove 24 on the supporting platform 2.

[0050] After the cutting, the resetting process is completed. Fig.14As shown, when the sliding part 4 slides to the point where the push rod 84 thereon pushes against the first pressure sensor 85 at the end of the piston cylinder 74, the first pressure sensor 85 transmits a pressure signal to the controller 89, and the controller 89 controls the servo motor 23 to stop, and at the same time, controls the drive motor 39 to start, driving the drive gear 40 to rotate, thereby driving the driven gear 37 to rotate, so that the fixing ring 51 stops working after rotating 180°, so that the curved guide plate 52 rotates to disengage from the third ball head 66, and the restriction on the third ball head 66 is released, and under the elastic reset force of the second reset spring 56, the guide part 14 is driven to slide upward as a whole, and then under the elastic reset force of the third reset spring 64, the cutting part 9 is driven to slide upward and disengage from the pipe 5 to be cut; in this state, the first ball head 31 on the U-shaped conveying platform 3 slides downward under the pressure of the first cam 41 ... curved guide plate 52 rotates to disengage from the third ball head 66, and the restriction on the third ball head 66 is released, and under the elastic reset force of the second reset spring 56, the guide part 14 is driven to slide upward as a The corresponding second ball head 32 is pressed against the pipe 5 to be cut; the corresponding first ball head 31 on the slide plate 6 is disengaged from the second cam 49, and the corresponding first ball head 31 is driven to press against the rotating rod 46 under the elastic resetting force of the corresponding first resetting spring 33, and the corresponding second ball head 32 is disengaged from the pipe 5 to be cut. At this time, the sliding part 4 can slide freely along the pipe 5 to be cut, while the pipe 5 to be cut remains stationary; the servo motor 23 is controlled to start, driving the screw rod 22 to rotate in the opposite direction, thereby driving the sliding part 4 to slide in the opposite direction, until the second extension plate 75 presses against the second pressure sensor 88, and the second pressure sensor 88 transmits the pressure signal to the controller 89. The controller 89 controls the servo motor 23 to stop working, completing a cutting cycle, and repeating the above operations to realize the automated equal-length feeding and equal-length cutting of the pipe 5 to be cut, thereby improving the production efficiency of the luggage pull rods.

[0051] For example 3, please refer to Figure 1-14 , this third embodiment makes the following improvements on the basis of the second embodiment. Specifically, a second extension plate 75 is fixed to the side surface of the other sliding rod 8; a piston rod 76 is fixed to the side surface of the second extension plate 75; the end of the piston rod 76 is fixed to a piston plate 77 that slides with the piston cylinder 74; the end of the piston cylinder 74 is connected to a suction pipe 78 that passes through the top of the cutting fluid storage box 72 and extends close to the inner bottom surface of the cutting fluid storage box 72; a discharge pipe 79 is provided on the side surface of the piston cylinder 74 near its end; and both the suction pipe 78 and the discharge pipe 79 are provided with a one-way valve.

[0052] U-shaped tubes 80 are symmetrically fixed on the top of the U-shaped frame 68; nozzles 81 that penetrate the U-shaped frame 68 and are tilted downward are fixed at the ends of the U-shaped tubes 80; nozzles are installed at the ends of the nozzles 81; an infusion tube 82 is connected between the two U-shaped tubes 80; a branch tube 83 is connected to the infusion tube 82; a hose is connected between the branch tube 83 and the drainage tube 79.

[0053] Working principle of the third embodiment:

[0054] By setting a one-way valve on the suction pipe 78, the cutting fluid in the cutting fluid storage box 72 can only be drawn into the piston cylinder 74 through the suction pipe 78; by setting a one-way valve on the discharge pipe 79, the cutting fluid in the piston cylinder 74 can only be sent into the branch pipe 83 through the discharge pipe 79 and the hose in sequence.

[0055] As the sliding portion 4 slides toward the direction approaching the supporting platform 2, it drives the piston plate 77 to slide in the piston cylinder 74, and the cutting fluid in the piston cylinder 74 is sent to the branch pipe 83 through the drain pipe 79 and the hose in turn, and finally sprayed to the cutting position through the nozzle at the end of the nozzle 81, thereby cooling the cutting process and flushing the cutting debris into the collection box 19.
