[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for distinction.
[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] like Figures 1 to 4 As shown, the unloading mechanism with the ejector rod comprises a positioning cover 71 arranged on the unloading station of the transport platform 5, a moving arm 72 arranged on the positioning cover 71 and movable relative to the positioning cover 71, and a driving member for driving the moving arm 72 to move; the moving arm 72 is provided with a forward extending ejector assembly 721 and an ejector rod 722, the ejector assembly 721 is used to abut against the positioning plate 821 of the bag buckle transfer module 8 to push the first movable seat 82, and the ejector rod 722 can pass through the positioning plate of the bag buckle transfer module 8 and eject the packaging bag located in front of the positioning plate. The utility model adopts the bag buckle transfer module on the transport platform with the positioning cover limited, and at the unloading position, the positioning plate of the bag buckle transfer module is ejected separately by the moving arm, so that the positioning plate drives the packaging bag to be unloaded to move to one side of the unloading device, and during the movement, the ejector rod passes through the positioning plate to directly contact and eject the packaging bag, so as to prevent the packaging bag from sticking to the positioning plate, thereby playing the effect of assisting the packaging bag to be separated from the buckle transfer module.
[0026] In the embodiment of the utility model, Figure 4As shown, the ejector assembly 721 adopts an elastic structure, and its specific structure is: the ejector assembly 721 includes a guide sleeve 7211 arranged on the movable arm 72, a movable ejector 7212 sleeved on the guide sleeve 7211, and an elastic member 7213 arranged between the guide sleeve 7211 and the movable ejector 7212. In this way, after the positioning plate is pushed to move into position, and the positioning plate does not move, the ejector rod 722 can continue to move forward relative to the positioning plate so that the ejector rod 722 can pass through the positioning plate to eject the packaging bag. In this process, since the movable arm 72 continues to move, the movable ejector rod 7212 can move relative to the guide sleeve 7211 after being pressed by the positioning plate. When the positioning plate is not in place, the movable ejector rod 7212 contacts the positioning plate under the pressure of the elastic member 7213 and can push the positioning plate to move together.
[0027] In this solution, a positioning cover 71 is used in conjunction with the bag buckle transfer module 8 so that the positioning plate 821 is limited after moving to a certain position and cannot move forward any further. Specifically, a limiting member 74 for limiting the first movable seat 82 is also provided in the positioning cover 71.
[0028] Specifically, in the present solution, the limit member 74 adopts a mounting arm extending forward and a block located at the front end of the mounting arm and protruding upward. Correspondingly, the first movable seat 82 on the bag buckle transfer module has a tail end 820 extending downward on the rear side. When the bag buckle transfer module moves into the positioning cover 71, the tail end is opposite to the block of the limit member 74 and has a certain interval. When the movable arm moves forward, the positioning plate is pushed to move the first movable seat 82 forward. When it moves to the tail end and abuts against the block, the positioning plate is in place. In the process of the movable arm continuing to move forward, the positioning plate cannot be pushed forward any further.
[0029] In the embodiment of the utility model, at least the front end of the ejector rod 722 is a ejector portion 7221 that can pass through the positioning plate. The ejector portion 7221 is a slender rod that is mainly used to pass through the body of the positioning plate, so the length of the ejector portion 7221 must be at least longer than the thickness of the body of the positioning plate.
[0030] In this solution, in order to push the positioning plate more smoothly, two sets of the ejector assemblies 721 and ejector rods 722 are provided on the movable arm 72, and the two sets of the ejector assemblies 721 are arranged opposite to each other, and the two sets of the ejector rods 722 are arranged opposite to each other. Similarly, since the packaging bag itself is relatively wide, the rear end of the packaging bag is ejected from both sides by two sets of ejector rods 722 to assist it to fall well into the unloading device. Correspondingly, a through hole or notch is also provided on the body of the positioning plate for the ejector rods 722 to pass through. After the buckle is pressed in this solution, the surface of the handle buckle covers the through hole, so that the ejector rod 722 directly contacts the handle buckle when ejecting, thereby ejecting the entire packaging bag. Of course, the ejector rod 722 can also be used to push the bag body of the packaging bag, which also has the surface effect of assisting the packaging bag to separate from the positioning plate.
[0031] In order to better separate the packaging bag from the positioning plate and unload it, the first connecting arm 7201 and the second connecting arm 7202 extending forward are provided on both sides of the moving arm 72, and the front ends of the first connecting arm 7201 and the second connecting arm 7202 are both provided with air nozzles 73. That is, after the ejection position, the air nozzle can blow air toward the bag body of the packaging bag to assist the packaging bag to separate from the buckle transfer module.
[0032] Moreover, in this solution, the position of the air nozzle 73 is roughly flush with the front end of the ejector rod 722, making the entire structural design more reasonable, and conveniently when the bag buckle transfer module moves into the positioning cover 71, the ejector rod assembly 721, the ejector rod 722, the first connecting arm 7201 and the second connecting arm 7202 are all located at the rear side of the positioning plate 821.
[0033] In this solution, the positioning cover 71 includes a top plate 711 and a back plate 712, the top plate 711 and the back plate 712 are connected to form an L-shaped structure, and the moving arm 72 is connected to the lower end of the top plate 711. The positioning cover 71 forms a material unloading station on the transport platform.
[0034] In the embodiment of the utility model, notches 82101 are provided on both sides of the positioning plate 821 of the bag buckle transfer module, and the first connecting arm 7201 and the second connecting arm 7202 are opposite to the notches 82101 on both sides, and ensure that the air nozzle 73 falls on the notch and can blow air onto the bag body of the packaging bag through the notch 82101.
[0035] In the embodiment of the utility model, the top plate 711 is further provided with a material discharging stopper 75 for limiting the bag clamping and positioning assembly 86 on the bag buckle transfer module 8. When the first movable seat 82 moves forward, the bag clamping and positioning assembly 86 is blocked by the material discharging stopper 75 of the present solution, so that it changes to a released state, and at this time, the first clamping jaw and the second clamping jaw that clamp the packaging bag on the positioning plate will be loosened, so that the packaging bag with the press buckle can be separated from the bag buckle transfer module 8 to complete the unloading.
[0036] The utility model also provides an automatic crimping device, comprising a crimping machine, on which the above-mentioned feeding mechanism with a ejecting rod is provided.
[0037] The novel buckle transfer module of the utility model embodiment is combined with a bag clamping positioning component, and adopts a positioning cover to limit the buckle transfer module on the transport platform. In the unloading position, the first movable seat is independently ejected by the ejection arm, so that its positioning plate drives the packaging bag with the buckle to move forward to the position where it is docked with the unloading mechanism, and after it is in place, the air nozzle of the ejection arm can blow air to assist the packaging bag to separate from the buckle transfer module.
[0038] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
