Description

Technical Field

[0001] The utility model relates to the technical field of finger cot packaging machines, in particular to a bag supporting device for a finger cot packaging machine. Background Technique

[0002] In the finger cot packaging and processing industry, traditional packaging methods usually rely on manual operations to complete. Specifically, the bag mouth of the packaging bag needs to be opened, and then workers put the finger cots into the bag and then seal it. This packaging method has several obvious problems:

[0003] Low efficiency: Due to relying on manual operations, the packaging process of each finger cot takes time, resulting in a low overall production efficiency. In the case of a large production volume, workers need to spend a lot of time to complete the packaging, which not only increases the labor cost but also limits the expansion of the production scale.

[0004] High labor intensity: Operations such as opening the bag mouth of the packaging bag and placing the finger cots require workers to continuously repeat manual actions during work, which undoubtedly increases the labor intensity. Long-term work may cause workers to become fatigued, which in turn affects the production quality and efficiency.

[0005] Therefore, we urgently need to design a bag supporting device for a finger cot packaging machine, which can automatically complete the operation of opening the bag mouth. Content of the Utility Model

[0006] In order to solve the problems existing in the above background technique, the utility model provides a bag supporting device for a finger cot packaging machine, which can automatically complete the operation of opening the bag mouth.

[0007] The technical solution of the utility model is: a bag supporting device for a finger cot packaging machine, including a packaging bag feeding platform, on which at least two groups of supporting clamping plates are provided. The supporting clamping plates include floating clamping plates and fixed clamping plates. The floating clamping plates and the fixed clamping plates are respectively used to clamp the upper and lower edges of the bag mouth of the packaging bag, and can open or close the bag mouth of the packaging bag.

Detailed implementation mode

[0028] The present utility model will be further described below in conjunction with the attached drawings and embodiments.

[0029] Embodiment 1

[0030] As Figures 1-6 shown, the bag supporting device for a finger cot packaging machine includes a packaging bag feeding platform 1. The packaging bag feeding platform 1 is used to provide packaging bags. One end thereof is provided with a packaging bag roll, and the other end is connected to a slitting device. The packaging bags are drawn out from the roll, and when passing through the middle position of the packaging bag feeding platform 1, finger cots are put in, and then the slitting device is used to singly cut the packaged packaging bags. At least two groups of supporting clamping plates are provided on the packaging bag feeding platform 1 for the packaging bags 8. The two groups of supporting clamping plates are separately arranged, one group is close to the roll, and one group is close to the slitting device. Specifically, the supporting clamping plates include a floating clamping plate 2 and a fixed clamping plate 3. The floating clamping plate 2 is used to clamp the upper edge of the bag mouth of the packaging bag 8, and the fixed clamping plate 3 is used to clamp the lower edge of the bag mouth of the packaging bag 8. The two cooperate to be used for opening or closing the bag mouth of the packaging bag 8. As Figure 1 、 2 shown, among them, in the finger cot packaging and processing process, a finger cot conveyor 9 parallel to the packaging bag feeding platform 1 is provided on one side of the packaging bag feeding platform 1. A clamping mechanism 10 is arranged between the packaging bag feeding platform 1 and the finger cot conveyor 9. The clamping mechanism 10 can pick up the finger cots on the finger cot conveyor 9 and send them into the packaging bags on the packaging bag feeding platform 1. The clamping mechanism 10 is roughly located at the middle position between the two groups of supporting clamping plates. When loading the bags, it is necessary to first open the bag mouth of the packaging bag 8, then put the finger cots in, and then close the bag mouth of the packaging bag 8 after putting them in. By providing at least two groups of supporting clamping plates, the present utility model can open the bag mouth of the packaging bag 8 from both sides of the finger cot putting position for the clamping mechanism 10 to extend into.

[0031] Specific reference Figures 3-4The floating clamping plate 2 includes a first bottom support 21, a lower clamping plate, a tension spring 24 and an extension portion 25. The first bottom support 21 is adjustably fixed to the upper end surface of the packaging bag 8 feeding platform 1 through a screw (the screw is not shown). The lower clamping plate is L-shaped, which includes a horizontal portion 22a and a vertical portion 22b. The vertical portion 22b is arranged on the first bottom support 21 through a slide rail 27 and a slider structure. Specifically, the slide rail 27 is arranged on the first bottom support 21 along the vertical direction, and the slider and the vertical portion 22b of the lower clamping plate are connected to each other. 2b is fixedly connected, and the slide rail 27 and the slider cooperate, so that the lower clamping plate can slide up and down along the slide rail 27, wherein the upper clamping plate 23 is parallelly arranged on the top side or bottom side of the horizontal part 22a of the lower clamping plate (the figure only shows that the upper clamping plate 23 is arranged on the top side of the horizontal part 22a of the lower clamping plate, and the structure arranged on the bottom side only needs to flip the upper clamping plate 23 180 degrees along the center line of the horizontal part 22a), and the upper clamping plate 23 and the horizontal part 22a of the lower clamping plate together form a clamping nozzle; the clamping nozzle is used to clamp the upper edge of the bag opening of the packaging bag 8.

[0032] It also includes a trigger mechanism. The specific structure of the trigger mechanism can be referred to Figure 3 , which includes a touch rod 62 and a linear slide 61 for driving the touch rod 62. The touch rod 62 is arranged on the linear slide 61 and moves synchronously with the linear slide 61. When the touch rod 62 moves, it will drive the lower clamping plate to slide upward or downward along the first bottom support 21. An extension portion 25 is arranged on one side of the vertical portion 22b of the lower clamping plate. The extension portion 25 is just located on the movement path of the touch rod 62. The extension portion 25 is preferably a rod-shaped structure. The end of the touch rod 62 away from the linear slide 61 (that is, the end close to the extension portion 25) is bent downward. When the touch rod 62 moves toward the lower extension portion 25, the bending position first contacts the extension portion 25. As the touch rod 62 continues to move, the extension portion 25 is extended. The extension portion 25 slides upward relative to the first bottom support 21, which causes the lower clamping plate to rise upward, and correspondingly, the upper edge of the bag opening of the packaging bag 8 clamped by the clamping nozzle is also stretched upward, while the fixed clamping plate 3 holds the lower edge of the packaging bag 8 stationary, so that the bag opening will be stretched open. When the touch rod 62 retreats, the bag opening needs to be closed to facilitate the forward transmission of the packaging bag, so the lower clamping plate needs to be quickly reset, which can be achieved by providing a tension spring 24. Specifically, one end of the tension spring 24 is connected to the vertical portion 22b of the lower clamping plate, and the other end of the tension spring 24 is connected to the first bottom support 21; the tension of the tension spring 24 can make the lower clamping plate slide downward and quickly reset.

[0033] In addition, it should be noted that the linear slide 61 is arranged between the packaging bag feeding platform 1 and the finger sleeve conveyor 9 through the connecting plate 6, and the clamping mechanism 10 is installed on the platform of the linear slide 61. When the clamping mechanism 10 clamps the finger sleeve from the finger sleeve conveyor 9, it moves toward the packaging bag feeding platform 1. At this time, the touch rod 62 moves in the same direction with it, and will first touch the extension part 25 to open the bag mouth of the packaging bag 8, and then the clamping mechanism 10 puts the finger sleeve into the packaging bag. Through the above structural design, the bag filling step is linked to the bag holding step, and the bag mouth can be opened when filling the bag, and the bag mouth can be closed when taking the finger sleeve.

[0034] like Figure 4 As shown, a clamping plate groove 26 is provided on the side where the horizontal portion 22a of the lower clamping plate and the upper clamping plate 23 are close to each other, and the clamping plate groove 26 is adapted to the self-sealing edge of the packaging bag 8. The clamping plate groove 26 is provided to limit the seal on the self-sealing edge of the packaging bag 8 so that it is always restricted to move in the clamping plate groove 26, which can not only prevent the bag opening from being separated from the clamping nozzle, but also make it easier to align the upper and lower seals in the subsequent sealing step.

[0035] Figure 4 The figure also shows the pin 4 and the spring 5, wherein the upper clamping plate 23 and the horizontal part 22a of the lower clamping plate are penetrated by the pin 4 in the vertical direction, and one end of the pin 4 is fixedly connected to the lower clamping plate. Specifically, the end of the pin 4 is provided with an external thread, and the horizontal part 22a of the lower clamping plate is provided with a corresponding external thread, and the internal thread and the external thread match each other. The upper clamping plate 23 is slidably connected with the pin 4, and the spring 5 is sleeved on the pin 4, and one end of the spring 5 abuts on the upper clamping plate 23, and the other end of the spring 5 abuts on the head of the pin 4. The spring 5 applies a pressure to the upper clamping plate 23, so that the clamping nozzle has a clamping force on the upper edge of the bag opening of the packaging bag 8.

[0036] like Figure 1 , 2 As shown in Figures 5 and 6, the fixed clamping plate 3 includes a second bottom support 31 and a pressing plate 32, and the pressing plate 32 is adjustably connected to the second bottom support 31 through an adjusting screw 33. The fixed clamping plate 3 is used in conjunction with the floating clamping plate 2, and the two are a set. The fixed clamping plate 3 is used to clamp the lower edge of the bag opening of the packaging bag 8, and it presses the lower edge of the bag opening of the packaging bag 8 onto the packaging bag feeding platform 1 through the pressing plate 32. When the floating clamping plate 2 props up the upper edge, the lower edge is in a fixed state.

[0037] In addition, a guide device is provided on one side of the second bottom support 31. The guide device is a rod-shaped structure with a certain elasticity, preferably made of iron wire or steel wire. It includes an integrally formed arc rod 7a and a straight rod 7b. One end of the arc rod 7a is fixed on one of the fixed clamps 3 near the starting end of the packaging bag feeding platform 1 (i.e., the side near the material roll). Specifically, the arc rod 7a is fixed on the second bottom support 31, and the other end of the arc rod 7a extends into the packaging bag 8. The arc top of the arc rod 7a is supported on the upper side wall of the packaging bag 8, and the end extends to the bottom of the packaging bag 8 and is connected to the straight rod 7b. The straight rod 7b faces the conveying direction of the packaging bag 8. By providing a guide device, not only can the bag mouth of the packaging bag 8 be opened, but also adsorption or adhesion between the inner side walls of the packaging bag can be prevented.

[0040] Specific reference Figure 7 The floating clamping plate 2 of this embodiment includes a first bottom support 21 and a lower clamping plate; the first bottom support 21 is adjustably fixed to the upper end surface of the packaging bag 8 feeding platform 1 through a screw (the screw is not shown), and the lower clamping plate is L-shaped, which includes a horizontal part 22a and a vertical part 22b, and the vertical part 22b is arranged on the first bottom support 21 through a slide rail 27 and a slider structure. Specifically, the slide rail 27 is arranged on the first bottom support 21 along the vertical direction, and the slider is fixedly connected to the vertical part 22b of the lower clamping plate. The slide rail 27 cooperates with the slider, so that the lower clamping plate can slide up and down along the slide rail 27, wherein an upper clamping plate 23 is provided in parallel to the top side or bottom side of the horizontal part 22a of the lower clamping plate (the figure only shows that the upper clamping plate 23 is arranged on the top side of the horizontal part 22a of the lower clamping plate, and the structure arranged on the bottom side only needs to flip the upper clamping plate 23 180 degrees along the center line of the horizontal part 22a), and the upper clamping plate 23 and the horizontal part 22a of the lower clamping plate together form a clamping nozzle; the clamping nozzle is used to clamp the upper edge of the bag opening of the packaging bag 8.

[0041] It also includes a trigger mechanism, which in this embodiment is an electric push rod 28, which is connected to the lower clamping plate, specifically fixedly connected to the vertical portion 22b of the lower clamping plate, and the piston rod of the electric push rod 28 is vertically upward, consistent with the opening direction of the packaging bag 8. The electric push rod 28 can drive the lower clamping plate to slide up and down along the first bottom support 21, thereby realizing the opening and closing of the bag mouth of the packaging bag 8.
