Description

Technical Field

[0001] This utility model relates to the field of air column bag raw material processing technology, specifically an automatic feeding and cutting device for air column bag raw material processing. Background Technology

[0002] As a new type of cushioning packaging material, air column bags are increasingly widely used in the field of logistics and transportation packaging. In the production and processing of air column bags, the raw materials need to be continuously fed and cut to a fixed length to meet the requirements of subsequent heat sealing, inflation and other processing steps.

[0003] Currently, existing air column bag raw material processing, feeding, and cutting equipment generally suffers from insufficient raw material positioning stability during use. Since the raw materials in air column bags are mostly flexible plastic films, during the conveyor belt feeding process, factors such as the inertia of the conveyor belt and changes in the tension of the raw material itself can easily cause the raw material to shift or wrinkle. At the same time, when the cutting blade descends to cut, the raw material is prone to displacement due to the lack of an effective clamping and fixing structure, resulting in reduced cutting dimensional accuracy and problems such as uneven cutting edges and excessive cutting length deviation. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding and cutting device for processing raw materials in air column bags, which has the advantage of being able to limit and compress the raw materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding and cutting device for processing air column bag raw materials, comprising a support platform, support rollers installed on both sides of the top of the support platform, a conveyor belt drivenly installed on the top of the support rollers, both ends of the conveyor belt extending to the outside of the support platform, a rectangular frame installed on the outer end of the top of the support platform, an electric cylinder installed on the top of the rectangular frame, a lifting plate installed inside the rectangular frame through the output end of the electric cylinder, a cutting blade installed at the bottom of the lifting plate, connecting springs symmetrically installed at both ends of the bottom of the lifting plate, a pressing plate installed at the lower end of the connecting springs, limit baffles symmetrically installed on the front and rear sides of the top of the conveyor belt, an adjusting screw rotatably installed on the outside of the limit baffle, and a turntable installed outside the rectangular frame through the outer end of the adjusting screw.

[0006] As a preferred embodiment, a telescopic rod is installed at the center of the top of the clamping plate, and the upper end of the telescopic rod is connected to the bottom of the lifting plate.

[0007] As a preferred embodiment, vertical guide plates are installed at both ends of the top of the lifting plate, and the upper end of the vertical guide plate extends through to the top of the rectangular frame and is equipped with a first limiting plate.

[0008] As a preferred embodiment, longitudinal guide plates are installed at both ends of the outer side of the limiting baffle, and the outer ends of the longitudinal guide plates penetrate the rectangular frame and extend to the outside where a second limiting plate is installed.

[0009] As a preferred embodiment, legs are installed on both sides of the bottom of the support platform, and fixing blocks are installed at both the front and rear ends of the support roller shaft, with the bottom of the fixing blocks connected to the top of the support platform.

[0010] As a preferred embodiment, threaded holes are provided at the bottom of both the front and rear ends of the rectangular frame, and one end of the adjusting screw is located inside the threaded hole and threadedly installed.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses adjustable limit baffles on both sides of the conveyor belt to flexibly adjust the limit distance according to the material of the air column bag of different widths, effectively preventing the material from shifting to the left or right during the feeding process, ensuring the accuracy of the material conveying direction, and providing a guarantee for the subsequent cutting accuracy. A pressure plate and connecting spring are set at the bottom of the lifting plate, which, together with the guide of the telescopic rod, allows the pressure plate to contact the material before the cutting knife descends, and the spring elastic force to evenly press the material, avoiding the cutting size deviation or uneven edges caused by the material being displaced by force during cutting, and significantly improving the cutting accuracy.

[0013] 2. This utility model uses a telescopic rod to precisely guide the up-and-down movement of the pressing plate, effectively preventing the pressing plate from tilting due to uneven force or deviation in movement trajectory during the pressing of the material in the air column bag. This ensures that the pressing force of the pressing plate on the material is evenly distributed on the surface of the material, preventing damage to the material due to excessive local pressure, and preventing displacement during cutting due to insufficient local pressure. At the same time, this connection method also makes the movement coordination between the pressing plate and the lifting plate more stable, reducing shaking during the pressing process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figure 1 As shown, this utility model provides an automatic feeding and cutting device for processing raw materials in air column bags, including a support platform 1. Support rollers 2 are installed on both sides of the top of the support platform 1. A conveyor belt 3 is drivenly installed on the top of the support rollers 2. Both ends of the conveyor belt 3 extend to the outside of the support platform 1. A rectangular frame 4 is installed on the outer end of the top of the support platform 1. An electric cylinder 5 is installed on the top of the rectangular frame 4. The output end of the electric cylinder 5 passes through the inside of the rectangular frame 4 and is installed with a lifting plate 6. A cutting blade 7 is installed at the bottom of the lifting plate 6. Connecting springs 8 are symmetrically installed at both ends of the bottom of the lifting plate 6. A pressing plate 10 is installed at the lower end of the connecting springs 8. Limiting baffles 12 are symmetrically installed on the front and rear sides of the top of the conveyor belt 3. An adjusting screw 13 is rotatably installed on the outside of the limiting baffle 12. The outer end of the adjusting screw 13 passes through the outside of the rectangular frame 4 and is installed with a turntable 14.

[0023] This technical solution uses adjustable limit baffles 12 on both sides of the conveyor belt 3 to flexibly adjust the limit spacing according to the different widths of the air column bag raw materials, effectively preventing the raw materials from shifting left and right during the feeding process, ensuring the accuracy of the raw material conveying direction, and providing a guarantee for the subsequent cutting accuracy. A pressing plate 10 and a connecting spring 8 are set at the bottom of the lifting plate 6. With the guidance of the telescopic rod 9, the pressing plate 10 can contact the raw material before the cutting blade 7 moves down, and the spring elastic force can evenly press the raw material, avoiding the cutting size deviation or uneven edges caused by the displacement of the raw material due to force during cutting, and significantly improving the cutting accuracy.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a telescopic rod 9 is installed at the center of the top of the clamping plate 10, and the upper end of the telescopic rod 9 is connected to the bottom of the lifting plate 6.

[0026] Adopting such Figure 1 The technical solution shown uses the telescopic rod 9 to precisely guide the up-and-down movement of the pressing plate 10, effectively preventing the pressing plate 10 from tilting due to uneven force or deviation in movement trajectory during the pressing of the air column bag material. This ensures that the pressing force of the pressing plate 10 on the material is evenly distributed on the surface of the material, preventing damage to the material due to excessive local pressure or displacement during cutting due to insufficient local pressure. At the same time, this connection method also makes the movement coordination between the pressing plate 10 and the lifting plate 6 more stable, reducing shaking during the pressing process.

[0027] Secondly, in the technical solution, vertical guide plates 11 are installed at both ends of the top of the lifting plate 6. The upper end of the vertical guide plate 11 extends through to the top of the rectangular frame 4 and is equipped with a first limiting plate 16. Longitudinal guide plates 15 are installed at both ends of the outer side of the limiting baffle 12. The outer end of the longitudinal guide plate 15 extends through the rectangular frame 4 and extends to the outside where a second limiting plate 17 is installed.

[0028] Its adoption is as follows Figure 1 The technical solution shown has the following characteristics: the vertical guide plate 11 provides precise guidance for the lifting movement of the lifting plate 6, preventing the lifting plate 6 from deviating or shaking when driving the cutting blade 7 to move up and down, ensuring that the cutting blade 7 always runs stably along the preset trajectory, and greatly improving the stability and accuracy of the cutting action; the longitudinal guide plate 15 can strictly constrain the movement direction of the limiting baffle 12, ensuring that the limiting baffle 12 always moves smoothly and linearly along the width direction of the conveyor belt 3 under the drive of the adjusting screw 13, without deviating or jamming, ensuring the accuracy of the spacing adjustment of the limiting baffle 12, thereby better adapting to air column bag raw materials of different width specifications and achieving reliable limiting.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-4 As shown, the support platform 1 has legs 18 installed on both sides of its bottom, and the support roller shaft 2 has fixing blocks 19 installed at both ends of its front and rear ends. The bottom of the fixing blocks 19 is connected to the top of the support platform 1. The rectangular frame 4 has threaded holes at both ends of its front and rear ends. One end of the adjusting screw 13 is located inside the threaded hole and is threaded.

[0031] Using the above technical solution, the support leg 18 can provide a stable support foundation for the entire equipment, effectively dispersing the weight and vibration generated during equipment operation, preventing the equipment from shaking or shifting due to unstable placement, and ensuring the smoothness of the feeding process of the conveyor belt 3 and the cutting process of the cutting blade 7; while the rectangular frame 4 has threaded holes at the bottom of the front and rear ends, which can accurately convert the rotational motion of the turntable 14 into the linear movement of the limit baffle 12, realizing fine adjustment of the spacing of the limit baffle 12 to adapt to the raw materials of air column bags of different widths.

[0032] The working principle of this utility model is as follows: According to the width specifications of the air column bag raw material to be processed, the turntable 14 is rotated, and the turntable 14 drives the adjusting screw 13 to rotate in the threaded hole of the rectangular frame 4, pushing the limiting baffle 12 to move along the longitudinal guide plate 15 until the distance between the two limiting baffles 12 is adapted to the width of the raw material. The free end of the air column bag raw material roll is laid flat on the conveyor belt 3, and the two sides of the raw material are attached to the limiting baffles 12. The external drive device drives the conveyor belt 3 to transmit the raw material to the cutting blade 7. When the raw material is conveyed to the set cutting length, the electric cylinder 5 is started and pushes the lifting plate 6 downward. The lifting plate 6 drives the pressing plate 10 to contact the surface of the raw material first. The connecting spring 8 is compressed and generates elastic pressure to press and fix the raw material. Then the lifting plate 6 continues to descend, and the cutting blade 7 contacts the raw material and completes the cutting.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
