Description

Technical Field

[0001] This utility model relates to the field of packaging bag sealing technology, and in particular to a packaging bag sealing feeding device. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. Widely used in daily life and industrial production, packaging itself has become increasingly commercially significant. It has become a special product no longer dependent on commodity production, but an indispensable and widely used product for all commodities. During processing, packaging bags require sealing strips to create a seamless seal around the edges.

[0003] As shown in the reference case "A sealing device for a food packaging bag" (publication number CN223341083U), a packaging bag is fixed between the fixing devices. A transverse guide rail is slidably connected to the fixing devices. A column is fixedly connected to the end of the transverse guide rail away from the fixing devices. A sliding rod is slidably connected between the two columns. A sealing device is installed at the lower end of the sliding rod. The sealing device includes a sealing strip and an extrusion plate. The extrusion plate is slidably connected to the sealing device. The sealing of the opening of the packaging bag is completed by installing the extrusion plate and the sealing strip in the sealing device. When the extrusion plate moves upward, it squeezes the molten softened plastic of the packaging bag upward with the sealing strip, preventing the liquefied plastic flowing down the sealing strip into the food during the sealing of the packaging bag.

[0004] According to the aforementioned references, the device uses two clamping blocks to hold and fix the food-containing packaging bag. By reducing the gap between the two clamping blocks, the packaging bag is clamped. Then, a fixing device is used to fix both sides of the packaging bag. The fixing device is installed on a transverse guide rail and can move laterally through the transverse guide rail. The fixing device moves back and forth through the guide groove opened in the transverse guide rail. However, when processing the packaging bag, the seal is prone to shifting during the feeding process, resulting in an unsatisfactory conveying effect of the transverse guide rail on the object. It is inconvenient to position and guide the packaging bag seal, thus reducing the effectiveness of the feeding device. Utility Model Content

[0005] Therefore, it is necessary to provide a packaging bag seal feeding device to address the problem of inconvenience in positioning and guiding the packaging bag seal.

[0006] The device includes a mounting frame, the inner wall of which is slidably connected to a conveyor frame; and a feeding mechanism, which is disposed at one end of the conveyor frame to feed the packaging bag seal and prevent the packaging bag seal from shifting. The feeding mechanism includes a conveying roller rotatably connected to one end of the conveyor frame, with limit rings slidably connected to both sides of the outer wall of the conveying roller, and sliders fixedly connected to both sides of the inner wall of the limit rings. A bidirectional lead screw is rotatably connected to one side of the inner wall of the conveying roller, and the two ends of the bidirectional lead screw are threadedly connected to two of the sliders respectively.

[0007] In one embodiment, the feeding mechanism further includes grooves formed on both sides of the outer wall of the conveying roller, and the slider engages with the grooves.

[0008] In one embodiment, the outer wall of the conveying roller is provided with several evenly arranged limiting grooves, and the limiting grooves are disposed on both sides of the two sliding grooves.

[0009] In one embodiment, a handle is fixedly connected to one end of the bidirectional lead screw, and the handle is rotatably connected to one end of the inner wall of the conveying roller.

[0010] In one embodiment, one side of the handle extends through to the outer wall of the conveyor roller.

[0011] In one embodiment, the other end of the conveyor frame is slidably connected to a mounting plate, and the bottom end of the mounting plate is rotatably connected to several evenly arranged rotating wheels. The outer wall of the rotating wheels is fixedly connected to a rubber ring, and the mounting plate is disposed on the other side of the conveyor roller.

[0012] In one embodiment, movable blocks are fixedly connected to both sides of the mounting plate, and movable grooves that fit into the movable blocks are provided on both sides of the inner wall of the conveyor frame.

[0013] In one embodiment, two electric push rods are fixedly connected to the top of the other end of the mounting bracket, with one end of each electric push rod passing through the mounting bracket and fixedly connected to the top of the movable block. Beneficial effects

[0014] 1. In the above-mentioned packaging bag sealing strip feeding device, the limiting rings on both sides of the conveying roller can contact the two sides of the seal to prevent the seal from shifting when the conveying roller is conveying the seal. The two limiting rings move by cooperating with the sliding grooves on the conveying roller through the sliders on both sides of the inner wall. The two sliders cooperate with the two ends of the bidirectional screw to drive the two limiting rings to move simultaneously, positioning and guiding the seal. The handle at one end of the bidirectional screw facilitates driving the bidirectional screw. The multiple limiting grooves on the surface of the conveying roller can limit the lateral displacement of the seal, ensuring that the seal maintains stable axial alignment during the conveying process and avoiding shifting. The sliding groove can guide the slider and limit the seal. It can prevent the seal from shifting when the seal is being fed, and can stably feed the packaging bag seal. 2. The mounting plate contacts the seal through multiple rotating wheels at the bottom, which can limit the movement of the seal. The multiple rotating wheels intersect to guide the seal in position. The mounting plate drives the moving block to slide along the inner wall of the moving groove via an electric push rod. The height of the rotating wheels can be adjusted. Both the moving block and the moving groove are T-shaped structures, which can drive the mounting plate to slide up and down. The rubber ring on the surface of the rotating wheel can increase the friction coefficient between the seal and the drive wheel, which can improve the conveying effect of the feeding device on the packaging bag seal.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes a packaging bag sealing strip feeding device.

[0020] In one embodiment, a packaging bag seal feeding device includes a mounting frame 100, with a conveyor frame 200 slidably connected to the inner wall of the mounting frame 100; a feeding mechanism 300, which can feed the packaging bag seal and prevent the packaging bag seal from deviating, is disposed at one end of the conveyor frame 200; wherein, the feeding mechanism 300 includes a conveying roller 310 rotatably connected to one end of the conveyor frame 200, a limit ring 320 slidably connected to both sides of the outer wall of the conveying roller 310, a slider 330 fixedly connected to both sides of the inner wall of the limit ring 320, and a bidirectional screw 340 rotatably connected to one side of the inner wall of the conveying roller 310, with the two ends of the bidirectional screw 340 respectively threadedly connected to two of the sliders 330.

[0021] like Figure 2 and Figure 3 As shown, the feeding mechanism 300 also includes grooves 350 formed on both sides of the outer wall of the conveying roller 310. The slider 330 is fitted into the grooves 350. Several evenly arranged limiting grooves 351 are formed on the outer wall of the conveying roller 310. Several limiting grooves 351 are set on both sides of the two grooves 350. One end of the bidirectional lead screw 340 is fixedly connected to a handle 360. The handle 360 ​​is rotatably connected to one end of the inner wall of the conveying roller 310. One side of the handle 360 ​​extends through to the outer wall of the conveying roller 310.

[0022] In this embodiment, when the seal passes through the conveyor roller 310, the bidirectional lead screw 340 inside the conveyor roller 310 is threadedly connected to two sliders 330, which can simultaneously drive two limiting rings 320 to move from both ends to the middle and contact the two sides of the seal, thereby limiting the seal and preventing the seal from deviating during feeding. The handle 360 ​​at one end of the bidirectional lead screw 340 facilitates driving the bidirectional lead screw 340. The conveyor roller 310 contacts the seal through the sliding groove 350 and multiple limiting grooves 351, which can position and guide the seal, provide stable feeding of the packaging bag seal, and improve the anti-deviation effect of the feeding device.

[0023] like Figure 4 and Figure 5 As shown, the other end of the conveyor frame 200 is slidably connected to the mounting plate 370. Several evenly arranged rotating wheels 371 are rotatably connected to the bottom end of the mounting plate 370. A rubber ring 372 is fixedly connected to the outer wall of the rotating wheel 371. The mounting plate 370 is set on the other side of the conveyor roller 310. Movable blocks 373 are fixedly connected to both sides of the mounting plate 370. Movable grooves 374 that fit into the movable blocks 373 are opened on both sides of the inner wall of the conveyor frame 200. Two electric push rods 375 are fixedly connected to the top of the other end of the mounting frame 100. One end of the electric push rod 375 passes through the mounting frame 100 and is fixedly connected to the top of the movable block 373.

[0024] In this embodiment, multiple rotating wheels 371 at the bottom of the mounting plate 370 can drive the moving block 373 to slide downward along the inner wall of the moving groove 374 via an electric push rod 375, thereby adjusting the position of the rotating wheels 371 so that the rotating wheels 371 and the rubber ring 372 come into contact with the seal, which can position and guide the seal and prevent the seal from shifting during transport.

[0025] Working principle: When the seal passes through the conveyor roller 310, the double-acting screw 340 is rotated by manually turning the handle 360. The two ends of the double-acting screw 340 are threadedly connected to two sliders 330 respectively. Two sliders 330 cooperate with the other two sliders 330 to drive the limiting ring 320 to move from both ends to the middle at the same time, so that one end of the limiting ring 320 contacts both sides of the seal for limiting. The conveyor roller 310 conveys the seal through the limiting groove 351 on its surface. The seal then passes through the other end of the conveyor frame 200. The two electric push rods 375 are extended by the external control component. One end of the electric push rod 375 drives the moving block 373 to slide the mounting plate 370 downward along the moving groove 374. The mounting plate 370 drives multiple rotating wheels 371 to contact the seal. The rotating wheels 371 cooperate with the rubber ring 372 to improve the conveying effect of the seal.

[0026] It should be noted that the electric linear actuator 375 and other devices mentioned above are all relatively mature devices with existing technologies. The specific model can be selected according to actual needs. The electric linear actuator 375 can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
