Processing apparatus for preparing a bagged product

Abstract

The application discloses a processing equipment for preparing bagged products, which comprises an equipment frame body, a material belt supply device, a slitting device and two turning devices. The material belt moving through the slitting device is slit to obtain a front belt and a back belt. The turning device comprises a turning assembly and at least two tension adjusting assemblies. The turning assembly comprises a turning roller one, a turning roller two and a turning roller three. The front belt and the back belt are transmitted through two turning roller threes respectively, so that the front belt and the back belt are oppositely arranged and the front pattern and the back pattern are opposite. Each turning roller two is driven by the tension adjusting assembly to be close to or away from the turning roller one on the same side. The application avoids the problem that the front pattern of the front belt and the back pattern of the back belt are misaligned due to the difference in unwinding speed. The tension of the front belt or the back belt is adjusted through the tension adjusting assembly, so that the packaging quality of the bagged products obtained subsequently is ensured.

Description

Technical Field

[0001] This application relates to the field of bagged product technology, and more particularly to processing equipment for preparing bagged products. Background Technology

[0002] Cosmetics, cleaning products, and other daily chemical products are typically packaged in different materials and shapes to meet the needs of different sales scenarios and user groups. Common packaging includes glass bottles, plastic bottles, and plastic bags. Bags are generally suitable for samples or single-use personal products.

[0003] Currently, during the production of bagged products, rolls of material with the front pattern and rolls of material with the back pattern are respectively installed on the unwinding rollers of two material supply devices and rotate together to unwind. They are then conveyed by the conveyor rollers of the two material supply devices in the form of front and back belts, so that the front and back belts are partially opposite each other and the front and back patterns are facing away from each other, and are conveyed to the hot pressing injection station.

[0004] Clearly, this process requires two sets of material supply devices, resulting in a complex structure and high equipment costs. Furthermore, because the rolls with the front and back designs are unwound separately, inconsistent unwinding speeds can occur. This causes the front and back rolls, which are positioned opposite each other, to continue being conveyed with their designs misaligned, affecting the packaging quality of the resulting bagged products. Additionally, tension fluctuations during the separate conveying of the front and back rolls can also cause misalignment of the front and back designs on the opposite sections of the front and back rolls, preventing the complete formation of the intended pattern on the surface of the bagged product and making it difficult to control the packaging quality.

The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0031] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] refer to Figures 1 to 3 The processing equipment for preparing bagged products according to a preferred embodiment of the present application will be described in detail below. The processing equipment for preparing bagged products includes an equipment frame 10 and a material supply device 20. The material supply device 20 is installed on the equipment frame 10. Single-sided double-pattern single rolls of material with front and back patterns printed on the same side are unwound by the material supply device 20 and conveyed in the form of a material belt.

[0034] Furthermore, the material supply device 20 includes an unwinding roller 21, which is rotatably mounted on the equipment frame 10. Single-sided double-image single roll material is sleeved on the unwinding roller 21 and rotates together with the unwinding roller 21 to unwind.

[0035] The material strip supply device 20 includes at least one conveyor roller 22, which is rotatably mounted on the equipment frame 10 and is axially parallel to the unwinding roller 21. The material strip unwound by the unwinding roller 21 is wrapped around the periphery of the conveyor roller 22 and conveyed by the conveyor roller 22.

[0036] The processing equipment for preparing bagged products also includes a slitting device 30, which is installed on the equipment frame 10. The slitting device 30 is located in the direction in which the material strip is conveyed by the material strip supply device 20 unwinding. The material strip passing through the slitting device 30 is slitted to obtain a front strip and a back strip.

[0037] Preferably, the unwinding roller 21 and the slitting device 30 are respectively located at the lower end and the upper end of the equipment frame 10. Multiple conveying rollers 22 are provided, and the strip unwound by the unwinding roller 21 is conveyed by the multiple conveying rollers 22 and guided to the slitting device 30, ensuring that the strip remains taut during conveying.

[0038] refer to Figure 4 The slitting device 30 includes a cutting blade 31, on which the material strip, unwound and conveyed by the material strip supply device 20, is conveyed to the cutting blade 31. The cutting blade 31 corresponds to the boundary area of ​​the front and back patterns of the material strip, and the material strip passing through the cutting blade 31 is slit into a front strip and a back strip.

[0039] It is worth mentioning that the slitting device 30 also includes a mounting component 32, which includes a movable component 321 and a fixed component 322. The fixed component 322 is mounted on the equipment frame 10. The movable component 321 is positioned on one side of the movement trajectory of the material strip unwound and conveyed by the material strip supply device 20, and the movable component 321 is mounted on the fixed component 322 in a direction parallel to the width direction of the material strip. The cutter 31 is mounted on the movable component 321 and moves together with it to adjust its position according to the actual position of the front and back pattern boundary area of ​​the material strip. Compared with adjusting the position of the material strip to adjust its boundary area, the operation is more convenient.

[0040] Furthermore, the mounting assembly 32 also includes a locking member 323, through which the movable member 321 is locked to the fixed member 322 to fix the cutter 31 in the moved position.

[0041] Preferably, the locking member 323 is implemented as a screw. The fixing member 322 has an insertion structure 32201 with its axial direction parallel to the width direction of the strip. The movable member 321 is movably inserted into the insertion structure 32201. The locking member 323 is threaded to the fixing member 322 forming one side wall of the insertion structure 32201 and extends into the insertion structure 32201 to abut against the portion of the movable member 321 placed within the insertion structure 32201, thereby locking the movable member 321 and the fixing member 322 together. When it is necessary to adjust the position of the cutter 31, loosen the locking member 323, push and pull the movable member 321 so that the movable member 321 drives the cutter 31 to move, and then tighten the locking member 323 to fix the movable member 321 and the cutter 31 in the moved position.

[0042] Preferably, the plug-in structure 32201 is implemented as a socket or slot.

[0043] In one embodiment, the locking member 323 includes an external thread and a threaded hole. Either the external thread or the threaded hole is formed in the fixed member 322, and the other is formed in the movable member 321. The movable member 321 is threadedly connected to the fixed member 322 through the engagement of the external thread and the threaded hole, and the movable member 321 is slidably connected to the equipment frame 10. The fixed member 322 is rotatably mounted on the equipment frame 10. Rotation of the fixed member 322 causes the movable member 321 to slide on the equipment frame 10. When the position of the cutter 31 needs to be adjusted, the fixed member 322 can be rotated. After the position adjustment is completed, the movable member 321 and the cutter 31 are fixed in the moved position by the engagement of the external thread and the threaded hole.

[0044] In another embodiment, the mounting component 32 is implemented as a cylinder, and the cutter 31 is mounted on the telescopic rod of the cylinder to be moved by it.

[0045] refer to Figures 2 to 3 The processing equipment for preparing bagged products includes two steering devices 40, which are arranged opposite to each other on the equipment frame 10. The front strip and the back strip obtained by the cutter 31 are respectively turned by the two steering devices 40 so that a portion is conveyed in a manner in which they are arranged opposite to each other and the front and back patterns are opposite to each other.

[0046] The steering device 40 includes a steering assembly 41, which includes a first steering roller 411, a second steering roller 412, and a third steering roller 413. The first steering roller 411 and the third steering roller 413 are all mounted on the equipment frame 10 and are all rotatable. The two first steering rollers 411 and the two third steering rollers 413 are positioned opposite each other between the two second steering rollers 412, and the two third steering rollers 413 are respectively positioned below the two first steering rollers 411. The first steering roller 411 is inclined, and its inclination direction forms an angle with the conveying direction of the portion of the material belt close to the cutter 31. The second steering roller 412 and the third steering roller 413 are axially parallel, and their axial directions are also parallel to the conveying direction of the portion of the material belt close to the cutter 31. The front or back strip, obtained by the cutter 31, is wrapped around the surface of the first guide roller 411 and conveyed to the second guide roller 412, and then conveyed to the third guide roller 413 via the second guide roller 412. The front and back strips are conveyed by the two third guide rollers 413 respectively, so that they are partially opposite each other and the front and back patterns are opposite to each other, so as to facilitate subsequent hot pressing and sample injection operations.

[0047] In this way, before hot-pressing and injection, the single-sided double-pattern single-roll material is unwound and split into a front strip and a back strip. By turning the front and back strips, they are conveyed close together with the front and back patterns facing away from each other. This process requires only one set of the material supply device 20. Compared to the common method of separately unwinding and conveying the front and back strips, this simplifies the structure, reduces equipment costs, and avoids the problem of the front pattern of the front strip and the back pattern of the back strip being misaligned due to differences in unwinding speed, thus improving the packaging quality of the subsequently obtained bagged products.

[0048] Preferably, the strip close to the cutter 31 is conveyed with the side printed with the front and back patterns facing down. The front strip obtained by the cutter 31 is conveyed by the guide roller 411 with the side printed with the front pattern or the back strip with the side printed with the back pattern attached to the outer periphery of the guide roller 411. The front strip is conveyed by the guide roller 413 with the side printed with the front pattern or the back strip with the side printed with the back pattern attached to the outer periphery of the guide roller 413.

[0049] As a deformable arrangement, the strip close to the cutter 31 is conveyed with the side printed with the front and back patterns facing upwards. The front strip obtained by the cutter 31 is conveyed by the guide roller 411 with the side opposite to the side printed with the front pattern or the back strip with the side opposite to the side printed with the back pattern attached to the outer periphery of the guide roller 411. The front strip is conveyed by the guide roller 413 with the side printed with the front pattern attached or the back strip with the side printed with the back pattern attached to the outer periphery of the guide roller 413.

[0050] refer to Figure 5 The steering device 40 includes at least two tension adjusting components 42. Each steering roller 2 412 is equipped with at least one tension adjusting component 42 and is driven by the tension adjusting component 42 to move closer to or away from the steering roller 1 411 on the same side, so as to adjust the tension of the front or back strip wrapped around the surface of the steering roller 2 412, so that the front and back strips, which are arranged opposite each other after passing through the two steering rollers 3 413, continue to be conveyed in such a way that the front pattern and the back pattern correspond, ensuring that the surface of the bagged product obtained at the end has a complete predetermined pattern, so that the packaging quality of the bagged product obtained later is guaranteed.

[0051] Further, the tension adjustment assembly 42 includes a sliding block 421 and a belt shifter 422, and the second steering roller 412 is rotatably mounted on the sliding block 421. The equipment frame 10 has at least two grooves 101. Each sliding block 421 is mounted on a groove 101 in a manner that allows it to slide closer to or away from the first steering roller 411 on the same side. The belt shifter 422 is threaded to one side wall of the groove 101 located in the sliding direction corresponding to the sliding block 421 and is rotatably connected to the sliding block 421. The belt shifter 422 rotates relative to the equipment frame 10 and moves in the direction of extending into or withdrawing from the groove 101, while simultaneously driving the sliding block 421 to slide within the groove 101, thereby adjusting the position of the second steering roller 412 relative to the first steering roller 411 on the same side, and thus adjusting the tension of the front or back belt.

[0052] Preferably, four tension adjustment components 42 are provided, and each of the two ends of the second steering roller 412 is respectively connected to a tension adjustment component 42, so that two tension adjustment components 42 can simultaneously drive one second steering roller 412 to slide, thereby improving the sliding stability of the second steering roller 412.

[0053] refer to Figures 1 to 3 as well as Figure 8 The equipment frame 10 has multiple injection ports 102, which are located above the guide roller 413. The processing equipment for preparing bagged products includes an injection device 50 and a hot-pressing device 60. The hot-pressing device 60 is located below the injection ports 102. The front and back strips are each conveyed by the guide roller 413, with portions arranged opposite each other and the front and back patterns facing away from each other, and are then conveyed to the hot-pressing device 60. The injection device 50 includes multiple injection guns 51, each of which is inserted into an injection port 102 with its lower end extending between the opposing portions of the front and back strips with opposite front and back patterns. The hot-pressing device 60 heat-presses the front and back strip portions together to form multiple bag cavities while the injection guns 51 inject samples into the bag cavities to obtain a material strip with sample-filled bag cavities.

[0054] Furthermore, the injection device 50 also includes at least one sample container 52, and the injection gun 51 is connected to the sample container 52 via a pipeline to supply sample to the injection gun 51.

[0055] Preferably, the number of sample barrels 52 is the same as the number of injection guns 51, and each injection gun 51 is connected to a sample barrel 52 through a pipeline so as to inject different samples simultaneously.

[0056] refer to Figure 3 The hot pressing device 60 includes a hot pressing component 61, which includes two sealing members 611 and at least one heat sealing assembly 612. The two sealing members 611 are arranged opposite each other, and the heat sealing assembly 612 is arbitrarily formed on the opposite portions. The heat sealing assembly 612 includes a plurality of side heating strips 6121 and at least one end heating strip 6122. The end heating strip 6122 is arranged horizontally, and the plurality of side heating strips 6121 are arranged vertically and distributed at equal intervals along the length direction of the end heating strip 6122. The lower ends of the side heating strips 6121 intersect with the end heating strip 6122, wherein each pair of adjacent side heating strips 6121 and one end heating strip 6122 together form a forming space 61201. A front strip and a back strip, arranged opposite each other and with the front and back patterns facing away from each other, are conveyed by the three guide rollers 413 and move between the two sealing members 611. The two sealing members 611 are arbitrarily driven to reduce the distance between them, so that the front and / or back strips corresponding to the side heating strip 6121 and the end heating strip 6122 that participate in forming each molding space 61201 are heat-pressed together to form multiple top-open cavities and obtain a strip with cavities. The lower end of the injection gun 51, which is inserted into each injection port 102, is placed in a cavity to inject sample into the cavity to obtain a strip with sample-filled cavities. The strip with sample-filled cavities is conveyed so that the top of the cavity corresponds to the end heating strip 6122, so that the end heating strip 6122 heat-presses the top of the cavity by the arbitrary movement of the two sealing members 611 to seal the cavity and complete the bagging.

[0057] The hot pressing device 60 further includes a hot pressing drive assembly 62, wherein the two sealing members 611 are arbitrarily installed on the hot pressing drive assembly 62 and driven by the hot pressing drive assembly 62 to reduce or increase the distance between them.

In this way, by rotating the corresponding sealing member 611 to offset it from the other sealing member 611, the orientation of the oppositely arranged front and back strips with their front and back patterns facing away can be adjusted.

[0060] refer to Figure 6Furthermore, the hot pressing device 60 also includes a first locking component 63. The sealing member 611, which is rotatably disposed on the equipment frame 10, is locked to the equipment frame 10 through the first locking component 63 to prevent the corresponding sealing member 611 from being pushed and rotating during the hot pressing process, thus affecting the hot pressing operation.

[0061] Preferably, the first locking assembly 63 includes a first crimping body 631 and at least one first locking member 632. The first locking member 632 includes a first insert 6321 and a first insertion hole 6322. Either the first insert 6321 or the first insertion hole 6322 is formed in the first crimping body 631, and the other is formed in the equipment frame 10. The first crimping body 631 is partially placed on the surface of the sealing member 611 rotatably disposed on the equipment frame 10, thereby locking the corresponding sealing member 611 to the equipment frame 10 through the insertion action of the first insert 6321 and the first insertion hole 6322.

[0062] Preferably, two first locking members 632 are provided. The first locking members 632 are assembled with the equipment frame 10 by means of two first inserts 6321 being respectively inserted into two first insert holes 6322, so that the corresponding sealing member 611 is firmly locked to the equipment frame 10.

[0067] Furthermore, the marking assembly 712 includes multiple sets of marking elements 7121 and a mounting body 7122. The marking elements 7121 imprint markings onto the heat-pressed portion of the material strip. The mounting body 7122 is detachably mounted to the imprinting element 711, and the multiple sets of marking elements 7121 are arranged at intervals and are all detachably connected to the mounting body 7122. In this way, when multiple marking elements 7121 are provided in a set, and the surface of the marking elements 7121 forms raised numbers, and the heat-pressed portion of the material strip is imprinted to form a date mark, the date can be changed by removing the mounting body 7122 and replacing individual marking elements 7121 in a set.

[0068] Preferably, the mounting body 7122 has a plurality of spaced-apart through slots 712201. When the mounting body 7122 is mounted on the embossing member 711, a group of marking members 7121 engage with one of the through slots 712201 and partially extend from the side of the mounting body 7122 away from the corresponding embossing member 711 to perform embossing marking. The marking assembly 712 also includes a plurality of connectors 7123, each connector 7123 including a connecting body 71231 and a connecting structure 71232.
