Description

Technical Field

[0001] The utility model relates to the technical field of product packaging, in particular to a film guiding device of a packaging machine and a packaging machine. Background Art

[0002] When packing stick ice cream, biscuits, tea cakes and other products in the packaging machine, the prepared products can be placed in the paper bag former through a conveying device such as a robot, and then the traction device pulls the packaging film and the product to move synchronously, and the packaging of the product is completed through longitudinal sealing and transverse sealing and cutting. However, in actual use, due to the different materials and widths of the packaging film, the tension of the packaging film is also inconsistent. When performing longitudinal sealing, it is easy to cause the longitudinal sealing film to fall off and fail to complete the sealing, or the height of the two sides of the packaging film is inconsistent, resulting in "whitening", etc., which seriously affects the packaging effect of the product.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] By adopting the above scheme, the user can control the adjustment rod to move along the first direction and the second direction, thereby driving the packaging film to deform, so that the forces on the two edge portions can be close, which can reduce the deviation of the packaging film, and also make the two edge portions be located in the limit groove with almost the same size, which is conducive to ensuring the reliable sealing of the two edge portions by the subsequent longitudinal sealing device, thereby reducing the film falling off and incomplete longitudinal sealing.

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0033] In the description of the embodiments of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, "coupling" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "sliding connection" means that the two are connected and can slide relative to each other after connection.

[0034] In the description of the embodiments of the present utility model, the term "a plurality of" means two or more.

[0035] In the description of the embodiments of the present utility model, the terms "include", "comprise" or any other variation thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including one..." does not exclude the presence of additional identical elements in the process, method, article or device including such element.

[0036] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of a packaging bag; Figure 2 which is a schematic structural diagram of a packaging film.

[0037] As Figure 1 and Figure 2 shown, the packaging bag 100 is usually formed by processing a packaging film 200 in a packaging machine. The specific processing process may include longitudinal sealing and transverse sealing and cutting, so that a complete packaging bag 100 can be formed. The packaging bag 100 may include a longitudinal sealing portion 110 and two transverse sealing portions 120 to ensure the tightness of the packaging bag 100.

[0038] The above-mentioned packaging bag 100 may specifically be used to package various food or non-food products such as stick ice cream, biscuits, tea cakes, instant noodles, etc., and no specific limitation is made here. That is to say, the embodiments of the present utility model do not limit the use scenario of the packaging bag 100, nor the use scenario of the packaging machine.

[0039] Among the longitudinal sealing portion 110 and the transverse sealing portion 120, the processing difficulty of the longitudinal sealing portion 110 is relatively large. Specifically, as Figure 2 shown, when processing the longitudinal sealing portion 110, it is necessary to curl the packaging film 200 so that the two edge portions 210 of the packaging film 200 can approach and fit, and then the longitudinal sealing device in the packaging machine seals the two edge portions 210.

[0040] However, the packaging films of different products may be made of different materials, and combined with the size differences of different products, etc., all of which may lead to inconsistent tensions of the packaging films, making it possible that the two edge portions may not be accurately fitted. Referring to Figure 2 for the orientation and positional relationship therein, that is, there may be a height difference at the top positions of the two edge portions. If this height difference is very large, it may cause one edge portion to fail to enter the longitudinal sealing device, resulting in poor conditions such as film dropping, incomplete longitudinal sealing, and failure to form the longitudinal sealing portion. In addition, there are usually pattern designs on the outer surface of the packaging film 200 for describing relevant information such as products and manufacturers, while the inner surface of the packaging film 200 is designed with a solid color (such as white); based on this, even if the aforementioned height difference is not very large and both edge portions can enter the longitudinal sealing device to complete the longitudinal sealing, there will still be a situation where the inner surface of one edge portion is exposed, resulting in "white exposure", which will also affect the quality and effect of product packaging.

[0041] In view of this, the embodiment of the present utility model provides a film guiding device, which can be used to guide and adjust the two edge portions 210, so that the two edge portions 210 can be relatively accurately fitted and longitudinally sealed, thereby reducing the aforementioned situations of film dropping and incomplete longitudinal sealing. At the same time, it can also reduce the situation of "white exposure", and can greatly improve the quality and effect of product packaging.

[0042] Please refer to Figures 3 - 7 , Figure 3 which is a schematic structural diagram of the film guiding device of the packaging machine provided by the embodiment of the present utility model; Figure 4 which is a diagram of the adjustment mechanism of the adjusting rod and the packaging film; Figure 5 which is Figure 4 a top view of the adjusting rod in Figure 6 which is a partial structural diagram of the bracket; Figure 7 which is Figure 6 a top view of

[0043] As Figure 3 shown, the film guiding device 300 includes a bracket 310 and an adjusting rod 320.

[0044] The bracket 310 can be fixedly arranged, specifically, it can be fixedly assembled in the packaging machine. The bracket 310 extends along the first direction X, and the adjusting rod 320 extends along the second direction Y. The first direction X and the second direction Y are arranged at an angle, and this angle can be, for example, 90 degrees, etc., and is not limited herein. The adjusting rod 320 is slidably connected to the bracket 310 along the first direction X, and the adjusting rod 320 is also slidably connected to the bracket 310 along the second direction Y. That is to say, the adjusting rod 320 can be displaced relative to the bracket 310 along the first direction X and the second direction Y.

[0045] Combined with Figure 4, the adjusting rod 320 has an adjusting end 321. The adjusting end 321 is provided with a limiting groove 321A for accommodating two edge portions 210 of the packaging film 200.

[0046] In specific use, the user can control the displacement of the adjusting rod 320 along the first direction X and the second direction Y, so as to drive the deformation of the packaging film 200, making the forces on the two edge portions 210 close to each other, reducing the deviation phenomenon of the packaging film 200, and enabling the two edge portions 210 to be located in the limiting groove 321A with nearly the same size, which is beneficial to ensuring the reliable sealing of the two edge portions 210 by the subsequent longitudinal sealing device, thus reducing the situations of film dropping and incomplete longitudinal sealing. At the same time, it can also reduce the situation of "white exposure", and can greatly improve the quality and effect of product packaging.

[0047] Moreover, for the same type of product, the setting of the above-mentioned film guiding device 300 can also control the stability of the size of the part of the edge portion 210 extending into the limiting groove 321A, that is, the size of the part of the edge portion 210 extending into the limiting groove 321A can be basically unchanged during the production process. In this way, it is also beneficial to ensure the consistency of the size of the subsequent formed packaging bag 100, and can greatly avoid bad phenomena such as over-width.

[0048] In some optional implementation manners, the adjusting rod 320 can be manually adjusted by the user. At this time, the structural form of the film guiding device 300 can be relatively simple.

[0049] Combined with Figure 3 , the film guiding device 300 provided by the embodiment of the present invention may further include a limiting member 330. The limiting member 330 may specifically be a nut, such as a wing nut, etc., so as to apply a rotational driving force to it. The adjusting rod 320 may include a main rod portion 322, and the main rod portion 322 may be provided with an external thread, and the main rod portion 322 may be threadedly connected to the limiting member 330. At the same time, the limiting member 330 is also used to abut against the bracket 310 along the second direction Y. In this way, the installation position of the adjusting rod 320 relative to the bracket 310 in the second direction Y can be effectively limited.

[0050] In specific use, by applying a rotational driving force to the limiting member 330, the adjusting rod 320 can be driven to perform a linear displacement along the second direction Y.

[0051] One adjusting rod 320 can be configured with two limiting members 330. As Figure 3 shown, the two limiting members 330 can be respectively located on both sides of the bracket 310 in the second direction Y, and both limiting members 330 can abut against the bracket 310. In this way, the installation reliability and stability of the adjusting rod 320 on the bracket 310 can be further improved.

[0052] It should be understood that in actual use, an adjusting rod 320 may also be configured with only one limiting member 330. Referring to Figure 3 the orientation and positional relationship in, the adjusting rod 320 may be provided with only one limiting member 330 located above the bracket 310. Through the abutment between the limiting member 330 and the bracket 310, the installation position of the adjusting rod 320 can also be limited.

[0053] The bracket 310 may also be provided with a guiding hole 311A extending along the first direction X. The adjusting rod 320 can be directly inserted into the guiding hole 311A and can slide along the guiding hole 311A in the first direction X. With such a setting, the sliding connection structure between the adjusting rod 320 and the bracket 310 in the first direction X can be relatively simple, and the guiding hole 311A can guide the sliding of the adjusting rod 320, which is beneficial to improving the smoothness and reliability of the sliding.

[0054] Combined with Figure 5 , a partial area of the outer peripheral wall of the adjusting rod 320 may be set as a flat portion 322A. The flat portion 322A may specifically be formed by cutting or grinding the outer peripheral wall of the adjusting rod 320. The flat portion 322A is used to abut against the inner hole wall of the guiding hole 311A to limit the rotation of the adjusting rod 320 around its own axis. In this way, the rotation of the adjusting rod 320 can be largely avoided. Correspondingly, the torsional deformation of the packaging film 200 caused by the adjusting rod 320 can also be largely avoided, which has relatively positive significance for ensuring the stable operation of the packaging film 200, as well as the packaging quality and packaging effect, etc.

[0055] It should be understood that the sliding connection structure between the adjusting rod 320 and the bracket 310 is not limited to the above description. In actual applications, those skilled in the art can also adjust the sliding connection structure between the adjusting rod 320 and the bracket 310 according to needs, as long as the usage requirements can be met. For example, it may further include a slider. The slider can be slidably connected to the bracket 310 along the first direction X, and the adjusting rod 320 can be slidably connected to the slider along the second direction Y. The adjusting rod 320 can still be installed and positioned on the slider through the limiting member 330.

[0056] In some optional implementation manners, the adjusting rod 320 can be automatically adjusted by a driving component. At this time, the degree of automation of the film guiding device 300 can be relatively high, and the labor intensity of the user can be relatively low.

[0057] In the embodiment of the present utility model, the film guiding device 300 may further include a first driving component. The first driving component can be connected to the adjusting rod 320 and is used to drive the adjusting rod 320 to displace along the first direction X.

[0058] Here, the embodiments of the present utility model do not limit the specific structural form of the above-mentioned first driving component. In practical applications, those skilled in the art can select according to specific needs as long as it can meet the usage requirements. For example, the first driving component can be a linear driving element such as a linear cylinder or a linear oil cylinder that can directly output linear displacement. Another example is that the first driving component can be a motor. In this case, the first driving component can also include a displacement conversion structure such as a gear-rack structure or a lead screw structure to convert the rotational displacement directly output by the motor into the linear displacement required by the adjusting rod 320.

[0059] In the embodiments of the present utility model, the film guiding device 300 may further include a second driving component. The second driving component can be connected to the adjusting rod 320 and is used to drive the adjusting rod 320 to displace along the second direction Y.

[0060] The specific structural form of the second driving component can be the same as that of the aforementioned first driving component, and no repetitive description will be made here.

[0061] In some alternative implementation manners, the number of the adjusting rods 320 can be multiple, and the adjusting rods 320 can be arranged at intervals along the first direction X.

[0062] In this implementation manner, the film guiding device 300 provided by the embodiments of the present utility model can simultaneously guide multiple packaging films 200 and is applicable to the use of a multi-channel packaging machine. It should be understood that the multi-channel packaging machine here means that the packaging machine can have multiple material channels at the same time, and packaging films 200 and products can be arranged in each material channel, which can improve the packaging efficiency. For example, in Figure 3 's implementation manner, the number of the adjusting rods 320 can be nine. At this time, the film guiding device 300 is applicable to the use of a nine-channel packaging machine.

[0063] In some alternative implementation manners, as Figure 6 and Figure 7 shown, the bracket 310 may include a main body portion 311 and a mounting portion 312.

[0064] The number of the mounting portions 312 can be two, and the two mounting portions 312 can be respectively located on both sides of the main body portion 311 in the first direction X. Both mounting portions 312 can be provided with mounting holes 312A for mounting and fixing the bracket 310. The main body portion 311 can be provided with the aforementioned guiding holes 311A for fitting and mounting the adjusting rod 320, and the adjusting rod 320 can slide relative to the main body portion 311 in the first direction X and the second direction Y.

[0065] Please refer to Figure 8 , Figure 8It is a relative position diagram of the film guiding device, longitudinal sealing device, cursor inspection device and packaging film in the packaging machine.

[0066] As Figure 8 shown, an embodiment of the present invention further provides a packaging machine, including a longitudinal sealing device 400, a film guiding device 300 and a cursor inspection device 500. The film guiding device 300 can be located upstream of the longitudinal sealing device 400, and the film guiding device 300 can be located downstream of the cursor inspection device 500. The film guiding device 300 can specifically be the film guiding device 300 of the packaging machine involved in the foregoing implementation manners.

[0067] Since the foregoing film guiding device 300 already has the above technical effects, therefore, the packaging machine having the film guiding device 300 should also have similar technical effects, so it will not be elaborated here.

[0068] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
