Description

Technical Field

[0001] This utility model relates to the field of directional feeding devices, specifically a directional feeding device for the production of high oxygen barrier preservation film. Background Technology

[0002] High oxygen barrier food preservation films are widely used in the packaging industry because they can effectively block oxygen penetration and extend the shelf life of food, pharmaceutical and other products. In its industrial production process, the film needs to go through multiple processes such as extrusion, stretching, printing and slitting. Oriented feeding is a key link connecting these processes—it is necessary to ensure that the film maintains a stable lateral position during transportation to avoid deviation, wrinkles or edge wear. Otherwise, it will directly affect the accuracy of subsequent processing (such as slitting size deviation) and the quality of the final product (such as damage to the oxygen barrier layer).

[0003] Currently, the industry primarily uses traditional conveying devices for directional feeding of food preservation films. These devices typically consist of a fixed support, drive rollers, and simple limiting components (such as rubber blocks). However, as high oxygen barrier film production moves towards "multi-specification, rapid changeover," traditional devices are gradually revealing the following technical limitations:

[0004] Poor adaptability of limiting components: Traditional devices often have fixed structures or modular designs that require disassembly and replacement, making them unable to flexibly adapt to films of different widths. When production needs are switched from narrow-width films to wide-width films, the machine must be stopped to disassemble the old limiting components and install the new ones, which is not only time-consuming (each switch takes 15-30 minutes) but also reduces the overall efficiency of the production line. To address this, we have proposed a high oxygen barrier food preservation film production directional feeding device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a directional feeding device for producing high oxygen barrier food preservation film, thus solving the aforementioned problems.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a directional feeding device for producing high oxygen barrier preservation film, comprising a concave support, a guide conveying shaft rotatably mounted on the inner side of the concave support, a motor fixedly mounted on the side of the concave support, the rotating shaft of the motor being fixedly connected to the guide conveying shaft, the motor driving the guide conveying shaft to rotate, grooves being provided at both ends of the guide conveying shaft, threaded connection structures being provided on both sides of the guide conveying shaft, one end of the threaded connection structure extending into the groove, and two limiting rings capable of lateral position adjustment being provided on the outer side of the guide conveying shaft, the limiting rings being connected to the threaded connection structures at corresponding positions.

[0007] Preferably, the threaded connection structure includes a rotating ring, a plugging protrusion, a plugging rod, a threaded ring, and a rotating connection structure. The rotating ring is disposed at both ends of the guide conveyor shaft. The rotating ring has an integrally formed plugging protrusion at the position corresponding to the groove. The plugging protrusion extends into the interior of the groove. Multiple sets of circular grooves are equally spaced on the groove. A plugging rod is inserted into the interior of the circular groove. A threaded ring is fixedly installed at the end of the plugging rod. An external thread is formed on the inner wall of the groove. The threaded ring is threaded together with the external thread. The outer side of the threaded ring is rotatably connected to the rotating connection structure, and the rotating connection structure is connected to the corresponding limiting ring.

[0008] Preferably, the end of the guide conveyor shaft is provided with an annular groove, and the inner side of the rotating ring is integrally formed with an annular protrusion, which is rotatably engaged with the annular groove.

[0009] Preferably, the rotatable connection structure includes a connecting ring rotatably disposed on the outside of the threaded ring, and the connecting ring is fixedly connected to a limiting ring at a corresponding position.

[0010] Preferably, the outer side of the connecting ring is integrally formed with a connecting rod, and a strip groove is opened at the position of the guide conveyor shaft corresponding to the connecting rod. The connecting rod extends to the outer side through the strip groove, and the connecting rod is fixedly connected to the inner wall of the limiting ring.

[0011] Preferably, a rotating groove is formed on the outer side wall of the threaded ring, and an annular rotating block is integrally formed on the inner side wall of the connecting ring, and the annular rotating block is rotatably engaged with the rotating groove.

[0012] Compared with the prior art, this utility model provides a directional feeding device for the production of high oxygen barrier food preservation film, which has the following beneficial effects:

[0013] This significantly improves the flexibility and adaptability of limit adjustment. The device uses a threaded connection structure to engage with a laterally adjustable limit ring. Without disassembling any parts, simply rotating the rotating rings at both ends drives the limit ring to move laterally along the guide conveyor shaft, achieving precise adjustment of the limit distance. This design can quickly adapt to high oxygen barrier preservation films of different widths, completely avoiding the downtime and disassembly process required when changing specifications in traditional devices, significantly shortening specification changeover time and improving the continuous operation efficiency of the production line.

[0014] This significantly improves the accuracy of positioning and conveying, ensuring the quality of the film product. The device employs a threaded drive (threaded ring engaging with the external thread of the groove's inner wall) combined with a multi-guided structure (circular groove and insert rod, strip groove and connecting rod) to ensure that the positioning ring moves smoothly along a fixed trajectory during adjustment, effectively controlling the positioning distance error to a very small range. This high-precision positioning avoids lateral deviation and edge friction wear of the film during conveying, while also preventing damage to the oxygen barrier layer of the ultra-thin high oxygen barrier film due to uneven stretching. This ensures the accuracy of subsequent processing and the oxygen barrier performance of the final product from the conveying stage.

[0015] The operation process is simplified, reducing the intensity of manual operation. The adjustment process of the device does not require additional tools such as wrenches and screwdrivers. The position of the limit ring can be adjusted by simply rotating the rotating ring manually, making the operation intuitive and convenient. At the same time, the rotating connection structure (rotational engagement between the connecting ring and the threaded ring) effectively avoids jamming problems during the adjustment process, reduces the frequency of repeated adjustments, and reduces the difficulty and labor intensity of workers' operation. It is especially suitable for high-frequency specification change scenarios in large-scale production lines.

[0016] The device also boasts advantages in terms of high conveying stability and equipment durability. The direct fixed connection between the guide conveyor shaft and the motor ensures stable power transmission and prevents slippage and wrinkles during film conveying. The various rotating mating structures (annular protrusions and annular grooves, annular rotating blocks and rotating slots) adopt a snap-fit ​​design, which not only ensures flexible rotation between components but also reduces relative wear, extends the overall service life of the device, and lowers equipment maintenance costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-4 A directional feeding device for producing high oxygen barrier food preservation film, with the following structure:

[0024] Concave support 1

[0025] The concave bracket 1 is the basic support component of the entire directional feeding device. The guide conveyor shaft 3 is rotatably mounted on its inner side, and the motor 2 is fixedly mounted on its side. Its main function is to provide a stable mounting and support foundation for core components such as the guide conveyor shaft 3 and the motor 2, ensuring that each component maintains a stable relative position during operation.

[0026] Motor 2

[0027] Motor 2 is fixedly mounted on the side of concave bracket 1, and its rotating shaft is fixedly connected to guide conveyor shaft 3. The core function of motor 2 is to provide power. When the device is started, motor 2 runs and drives the rotating shaft to rotate, which in turn drives guide conveyor shaft 3 to rotate synchronously, providing a power source for the directional conveying of the preservation film.

[0028] Guide conveyor shaft 3

[0029] The guide conveyor shaft 3 is the core conveying component of the device. It is rotatably mounted inside the concave bracket 1 and fixedly connected to the rotating shaft of the motor 2. Its surface is used to guide the preservation film. When the motor 2 drives it to rotate, it can drive the preservation film on the surface to achieve directional conveying. In addition, the guide conveyor shaft 3 has grooves 4 at both ends, an annular groove 5 at the end, and a strip groove 15 at the position corresponding to the connecting rod 16. These structures are used to cooperate in the installation of the threaded connection structure, the rotating ring 6, and the connecting rod 16.

[0030] Groove 4

[0031] The groove 4 is formed at both ends of the guide conveyor shaft 3 and serves as the installation and accommodating space for the threaded connection structure. Multiple sets of circular grooves 9 are equally spaced inside the groove 4, and external threads are formed on the inner wall. The groove 4 can accommodate the insertion protrusion 8, the insertion rod 10, and the threaded ring 11, providing a path for the lateral movement of the threaded ring 11. At the same time, the threaded transmission is realized through the engagement of the external threads on the inner wall with the threaded ring 11.

[0032] Annular groove 5

[0033] An annular groove 5 is formed at the end of the guide conveyor shaft 3 and is rotatably engaged with an annular protrusion 7 integrally formed on the inner side of the rotating ring 6. The function of this structure is to limit the lateral position of the rotating ring 6, prevent the rotating ring 6 from falling off the end of the guide conveyor shaft 3, and at the same time allow the rotating ring 6 to rotate flexibly around the end of the guide conveyor shaft 3.

[0034] Rotating ring 6

[0035] The rotating ring 6 is located at both ends of the guide conveyor shaft 3 and is the operating component for adjusting the position of the limiting ring 17. Its inner side has an integrally formed annular protrusion 7, while its outer side has no special protrusion structure. Corresponding to the groove 4, an integrally formed insertion protrusion 8 is present. The core function of the rotating ring 6 is to manually rotate it, causing the insertion protrusion 8 to rotate synchronously, thereby driving the threaded connection structure inside the groove 4 to operate, thus achieving the position adjustment of the limiting ring 17.

[0036] 7 ring-shaped protrusions

[0037] The annular protrusion 7 is an integrally formed structure on the inner side of the rotating ring 6, and it rotatably engages with the annular groove 5 at the end of the guide conveyor shaft 3. This structure, in conjunction with the annular groove 5, ensures that the rotating ring 6 can rotate stably around the guide conveyor shaft 3, and also provides lateral restraint for the rotating ring 6, preventing lateral displacement of the rotating ring 6 during rotation.

[0038] Plug protrusion 8

[0039] The insertion protrusion 8 is an integrally formed structure at the position of the rotating ring 6 corresponding to the groove 4, and extends into the interior of the groove 4. When the rotating ring 6 rotates, the insertion protrusion 8 will rotate synchronously with the rotating ring 6, thereby pushing or driving the threaded ring 11 inside the groove 4 (indirectly through the insertion rod 10), providing driving force for the rotation of the threaded ring 11, and finally realizing the lateral movement of the threaded ring 11.

[0040] Circular groove 9

[0041] Multiple sets of circular grooves 9 are equally spaced inside the groove 4, and insertion rods 10 are inserted inside them. The main function of the circular grooves 9 is to restrict the movement direction of the insertion rods 10, allowing the insertion rods 10 to move only along the axial (lateral) direction of the groove 4, preventing the insertion rods 10 from rotating with the threaded ring 11, and ensuring that the threaded ring 11 can smoothly achieve lateral displacement.

[0042] Connector 10

[0043] A threaded ring 11 is fixedly installed at the end of the plug rod 10, and the rod body is inserted into the inside of the circular groove 9. Its function is to connect the threaded ring 11 to the rotary drive structure. When the threaded ring 11 moves laterally due to its threaded engagement with the groove 4, it will drive the plug rod 10 to move laterally synchronously within the circular groove 9. At the same time, due to the restriction of the circular groove 9, the plug rod 10 will not rotate with the threaded ring 11.

[0044] Threaded ring 11

[0045] The outer wall of the threaded ring 11 is connected to the inner wall of the groove 4 by an external thread, and the inner side is fixedly connected to the end of the plug rod 10. A rotating groove 12 is provided on the outer wall. When the rotating ring 6 drives the plug protrusion 8 to rotate, it will indirectly drive the threaded ring 11 to rotate. Since the threaded ring 11 is threadedly engaged with the inner wall of the groove 4, the rotating threaded ring 11 will move along the axial (lateral) direction of the groove 4, thereby driving the connecting ring 13 and the limiting ring 17 to move laterally in sync.

[0046] Rotating slot 12

[0047] A rotating groove 12 is formed on the outer wall of the threaded ring 11 and is rotatably engaged with an annular rotating block 14 integrally formed on the inner wall of the connecting ring 13. The function of this structure is to realize the rotatable connection between the threaded ring 11 and the connecting ring 13, allowing the connecting ring 13 to rotate around the threaded ring 11, while ensuring that the connecting ring 13 can move laterally synchronously with the lateral movement of the threaded ring 11, thus avoiding motion interference between the two.

[0048] Connecting ring 13

[0049] The connecting ring 13 is rotatably positioned outside the threaded ring 11 and is the core component of the rotating connection structure. Its inner wall is integrally formed with an annular rotating block 14, and its outer wall is integrally formed with a connecting rod 16. The main function of the connecting ring 13 is to connect the threaded ring 11 and the limiting ring 17, transmitting the lateral movement of the threaded ring 11 to the limiting ring 17 via the connecting rod 16. Simultaneously, through its rotational engagement with the threaded ring 11, it prevents its own rotation from affecting the stability of the limiting ring 17.

[0050] Annular rotating block 14

[0051] The annular rotating block 14 is an integrally formed structure on the inner wall of the connecting ring 13, and it is rotatably engaged with the rotating groove 12 on the outer wall of the threaded ring 11. This structure, in conjunction with the rotating groove 12, enables the connecting ring 13 to rotate with the threaded ring 11, ensuring that the connecting ring 13 can move laterally with the threaded ring 11, while also being able to rotate flexibly relative to the threaded ring 11, preventing the connecting ring 13 from being driven to rotate by the rotation of the threaded ring 11.

[0052] 15 strip grooves

[0053] The slot 15 is formed at the position of the connecting rod 16 corresponding to the guide conveyor shaft 3. The connecting rod 16 extends through the slot 15 to the outside of the guide conveyor shaft 3. The function of the slot 15 is to provide a channel for the connecting rod 16 to move laterally, while restricting the direction of movement of the connecting rod 16, ensuring that the connecting rod 16 can only move along the axial (lateral) direction of the guide conveyor shaft 3 with the connecting ring 13, and to prevent the connecting rod 16 from deviating or getting stuck during movement.

[0054] Connecting rod 16

[0055] The connecting rod 16 is an integrally formed structure on the outside of the connecting ring 13. One end is fixed to the connecting ring 13, and the other end extends outward through the strip groove 15 on the guide conveying shaft 3 and is fixedly connected to the inner wall of the limiting ring 17. Its core function is to transmit motion, directly transmitting the lateral movement of the connecting ring 13 to the limiting ring 17, causing the limiting ring 17 to move laterally synchronously on the outside of the guide conveying shaft 3, thereby achieving position adjustment of the limiting ring 17.

[0056] Limiting ring 17

[0057] The limiting ring 17 is located on the outside of the guide conveyor shaft 3, and its inner wall is fixedly connected to the end of the connecting rod 16. Lateral position adjustment can be achieved through a threaded connection structure. Its main function is to limit the movement of the preservation film conveyed on the surface of the guide conveyor shaft 3. The distance between the two limiting rings 17 is adjusted according to the width of the preservation film to prevent lateral displacement of the preservation film during conveying, ensuring that the preservation film is always conveyed in the set direction.

[0058] The structure is connected as follows: it includes a concave bracket 1, a guide conveyor shaft 3 is rotatably mounted on the inner side of the concave bracket 1, a motor 2 is fixedly mounted on the side of the concave bracket 1, the rotating shaft of the motor 2 is fixedly connected to the guide conveyor shaft 3, the motor 2 is used to drive the guide conveyor shaft 3 to rotate, both ends of the guide conveyor shaft 3 are provided with grooves 4, and both sides of the guide conveyor shaft 3 are provided with threaded connection structures, one end of the threaded connection structure extends into the inside of the groove 4, and the outer side of the guide conveyor shaft 3 is provided with two limiting rings 17 that can be adjusted laterally. The limiting rings 17 are connected to the threaded connection structures at the corresponding positions. When it is necessary to directionally convey the preservation film, it is guided through the surface of the guide conveyor shaft 3, and then the motor 2 starts, driving the guide conveyor shaft 3 to rotate, guiding and directionally conveying the preservation film. At the same time, it is necessary to adjust the distance between the limiting rings 17 on both sides according to the width of the preservation film. By rotating the threaded connection structure, the distance between the two limiting rings 17 is adjusted so that the two limiting rings 17 limit the preservation film and guide it to be conveyed.

[0059] Furthermore, the threaded connection structure includes a rotating ring 6, an insertion protrusion 8, an insertion rod 10, a threaded ring 11, and a rotating connection structure. The rotating ring 6 is located at both ends of the guide conveyor shaft 3. The rotating ring 6 has an integrally formed insertion protrusion 8 at the position corresponding to the groove 4. The insertion protrusion 8 extends into the interior of the groove 4. Multiple sets of circular grooves 9 are equally spaced on the groove 4. The insertion rod 10 is inserted into the interior of the circular groove 9. The end of the insertion rod 10 is fixedly installed with a threaded ring 11. An external thread is formed on the inner wall of the groove 4, and the threaded ring 11 is threadedly connected to it. The outer side of 11 is rotated to connect to the rotating connection structure, which is connected to the corresponding limiting ring 17. When it is necessary to adjust the position of the limiting ring 17 outside the guide conveyor shaft 3, rotate the rotating ring 6, which then drives the insertion protrusion 8 to rotate. Since the threaded ring 11 is threadedly connected to the inner wall of the groove 4, the threaded ring 11 will move laterally inside it. At the same time, the insertion rod 10 will move inside the circular groove 9, which then drives the rotating connection structure to move laterally, and simultaneously drives the limiting ring 17 to move laterally, adjusting the distance between the two limiting rings 17.

[0060] Furthermore, an annular groove 5 is provided at the end of the guide conveyor shaft 3, and an annular protrusion 7 is integrally formed on the inner side of the rotating ring 6. The annular protrusion 7 is rotatably engaged with the annular groove 5.

[0061] Furthermore, the rotating connection structure includes a connecting ring 13 rotatably disposed on the outside of the threaded ring 11, and the connecting ring 13 is fixedly connected to the corresponding limiting ring 17.

[0062] Furthermore, the outer side of the connecting ring 13 is integrally formed with a connecting rod 16, and the guide conveying shaft 3 is provided with a strip groove 15 at the position corresponding to the connecting rod 16. The connecting rod 16 extends to the outside through the strip groove 15, and the connecting rod 16 is fixedly connected to the inner wall of the limiting ring 17.

[0063] Furthermore, a rotating groove 12 is provided on the outer wall of the threaded ring 11, and an annular rotating block 14 is integrally formed on the inner wall of the connecting ring 13. The annular rotating block 14 is rotatably engaged with the rotating groove 12.

[0064] Working principle: When the preservation film needs to be directionally conveyed, it is guided through the surface of the guide conveyor shaft 3. Then the motor 2 starts and drives the guide conveyor shaft 3 to rotate, guiding and directionally conveying the preservation film. At the same time, the distance between the two limiting rings 17 needs to be adjusted according to the width of the preservation film. By rotating the threaded connection structure, the distance between the two limiting rings 17 is adjusted so that the two limiting rings 17 limit the preservation film and guide it to be conveyed.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
