For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:
[0028] Embodiment 1:
[0029] like Figures 1 to 3As shown, this embodiment provides an automatic cutting device for reinforcing bottom strips of valve bags, including a workbench 1, a cutting mechanism 2 is provided on the workbench 1, both ends of the discharge side of the cutting mechanism 2 are provided with sensing devices 4, an automatic feeding mechanism 3 is provided on the feeding side of the cutting mechanism 2, a chute 5 for the automatic feeding mechanism 3 to approach the cutting mechanism 2 is provided on the workbench 1, and a driving device for the automatic feeding mechanism 3 to approach the cutting mechanism 2 is provided under the chute 5. The output end of the driving device is fixedly connected to the slider 32, and the slider 32 is driven to slide in the chute 5. The driving device of the present application can adopt existing driving structures such as a driving motor and a stepping motor, and can realize the horizontal movement of the automatic feeding mechanism 3 in the chute 5, which will not be described in detail in this article.
[0030] Specifically, the cutting mechanism 2 includes a mounting frame 21, a passage for the valve bag to pass through is provided between the mounting frame 21 and the workbench 1, a cutting knife 22 and a control device for driving the cutting knife 22 to move from the passage toward the workbench 1 are movably connected in the mounting frame 21, and a cutting groove 7 is provided on the workbench 1 directly below the cutting knife 22. The control device in this embodiment includes a driving structure such as a driving motor or a cylinder that drives the cutting knife 22 to move up and down in the vertical direction, and the control device also includes a control system using the prior art, which includes a controller such as a single-chip microcomputer, which can receive the blocking signal sent by the sensing device 4, and control the action of the driving structure of the cutting knife 22 according to the blocking signal of the sensing device 4, thereby controlling the action of the cutting knife 22, and can also detect whether the automatic feeding mechanism 3 reaches the limit signal in the limit groove 6, thereby controlling the action of the driving mechanism of the automatic feeding mechanism 3. The control system adopts the prior art and will not be described in detail in this application.
[0031] In order to prevent the cutting knife 22 from moving when the staff is taking the material, a sensing device 4 is fixedly arranged on the discharge side to identify the approach of a human body and control the cutting knife 22 to stop moving to protect the human body. The sensing device 4 includes a transmitting mechanism 41 and a receiving mechanism 42, which are symmetrically fixed at both ends of the discharge side of the cutting mechanism 2. The transmitting mechanism 41 and the receiving mechanism 42 both include a mounting shell 411, in which a triangular sensor 412 is fixed, and the mounting shell 411 is fixed on the side wall of the cutting mechanism 2 and is located above the workbench 1. The two triangular sensors 412 are arranged opposite to each other.
[0032] When there is an obstruction between the transmitting mechanism 41 and the receiving mechanism 42, an obstruction signal will be detected, and the control device can control the cutting knife 22 not to move according to the obstruction signal. Therefore, the sensing device 4 needs to be fixedly installed on the mounting frame 21 and at a certain distance from the workbench 1. This is to avoid misidentification when the automatic feeding mechanism 3 pushes the valve bag from the channel port to the discharge side if the sensing device 4 is at a low position. Therefore, the sensing device 4 needs to be fixedly set at a certain distance above the workbench 1. A baffle can also be fixed on the workbench 1 placed under the mounting frame 21 to support the sensing device 4.
[0033] In order to realize the automatic positioning of the cutting mechanism 2, a first positioning member 23 is fixedly provided above the cutting knife 22 on the feeding side, and the first positioning member 23 is parallel to the workbench 1 when the cutting knife 22 is completely moved into the cutting groove 7. In order to realize the automatic positioning of the automatic feeding mechanism 3, one end of the slide 5 close to the cutting groove 7 is connected to the limiting groove 6. The first positioning member 23 is fixedly installed above the blade of the cutting knife 22 and is arranged parallel to the workbench 1 toward the automatic feeding mechanism 3.
[0034] Specifically, the automatic feeding mechanism 3 includes a pushing block 31, a sliding block 32 matching the slide groove 5 is fixed on the side of the pushing block 31 away from the cutting knife 22, and a second positioning member 33 is fixed on the side of the pushing block 31 close to the cutting knife 22. The second positioning member 33 is staggered with the first positioning member 23. When the second positioning member 33 moves to the limiting groove 6 and the first positioning member moves to the bottom of the cutting groove 7 with the cutting knife 22, the first positioning member 23 and the second positioning member 33 overlap.
[0035] like Figure 2 As shown, the first positioning member 23 includes a plurality of first comb teeth, the second positioning member 33 includes a plurality of second comb teeth, and the first comb teeth and the second comb teeth are arranged alternately. The first comb teeth may be triangular comb teeth, and the second comb teeth may be rectangular comb teeth.
[0036] The automatic feeding mechanism 3 of the present application can push multiple valve bags for cutting at the same time. For example, the second positioning member 33 is divided into several feeding areas, each feeding area includes several second comb teeth for pushing the valve bag to move under the cutting knife 22, and all the second comb teeth are staggered with the first comb teeth.
[0037] The cutting mechanism 2 is located in the center of the workbench 1. In order to facilitate the staff to take materials, a clearance groove 8 is set at the position of the workbench 1 on the feeding side of the cutting mechanism 2 to facilitate the staff to take materials.
[0038] The usage process of this embodiment:
[0039] Put the valve bag to be cut into the feeding area so that the valve bag collides with the comb teeth of the second positioning member 33, and then start the driving device so that the slider 32 drives the pushing block 31 to move toward the cutting mechanism 2 in the slide groove 5 under the drive of the driving device, and the pushing block 31 pushes the reinforcing bottom strip of the valve bag to the cutting groove 7 below the cutting knife 22, and the second positioning member 33 is located below the first positioning member 23. At this time, start the driving motor of the cutting mechanism 2 so that the cutting knife 22 moves into the cutting groove 7 under the drive of the driving motor. When the cutting knife 22 moves into the cutting groove 7, the first positioning member 23 and the second positioning member 33 can overlap due to the staggered arrangement, and the first positioning member 23 can move onto the workbench 1.
[0040] After cutting is completed, the cut valve bag is manually taken out from the make way slot 8. At this time, when the staff reaches out to take out the valve bag from the channel, the sensing device 4 senses the human hand and generates a blocking signal. The control system controls the cutting knife 22 not to move to avoid harm to the human body.
[0041] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
