[0034] Compared with the prior art, the beneficial technical effects brought by the utility model are as follows:

[0035] 1. The utility model adopts a quick-release feeding tail rack, which has a quick-release function, which is convenient for cleaning the feeding tail rack, ensuring the cleanliness of the feeding tail rack and guaranteeing the hygiene of the materials to be packaged, especially for quick-frozen foods, there will be residual water vapor, which is convenient for cleaning the residual water vapor to avoid rusting of the equipment; for meat products, there will be some oil residues, and the quick-release feeding tail rack is easy to clean, which improves the cleanliness of the equipment and thus ensures food hygiene.

[0036] 2. In the utility model, the roll film forming device is arranged at the front end of the material conveying device, and the film feeding device is arranged below the material conveying device, that is, a bottom film feeding method is adopted. After the material to be packaged is output from the feed tail rack, it can enter the roll film forming device. As for the top of the roll film, direct contact between the material to be packaged and the material conveying device is avoided, which can effectively ensure the sanitary conditions of the packaged materials.

[0037] 3. The utility model sets the longitudinal sealing device above the material conveying device. On the one hand, it corresponds to the film forming method of the lower film. On the other hand, since the longitudinal sealing device relies on heat sealing to seal the two sides of the packaging film together, the temperature at the longitudinal sealing device is relatively high. If the upper film method is adopted, the high temperature of the longitudinal sealing device has a greater impact on the quick-frozen materials. In this way, the water vapor generated by the temperature change of the quick-frozen food will escape from the bottom, which will cause equipment corrosion for a long time. This application adopts the lower film method, combined with the form of the longitudinal sealing device being set at the top, the water vapor generated by the quick-frozen food will not leak into the material conveying device and below it, and will not affect the packaging equipment.

[0038] 4. The utility model sets protective covers on the longitudinal sealing device and the transverse sealing device. Since both the longitudinal sealing device and the transverse sealing device use high-temperature hot-sealing roll film, when quick-frozen or meat jerky foods pass through the device, some water vapor or oil vapor will be generated due to temperature changes. After the protective covers are set, the water vapor or oil vapor generated during the packaging process is prevented from escaping, and the electrical equipment of the packaging machine is prevented from being corroded and contaminated. 5. The utility model sets the electrical box on one side of the material conveying device. On the one hand, the electrical box can provide installation support for the longitudinal sealing device, and on the other hand, the electrical components are isolated from the material conveying device through the back plate of the electrical box to prevent the electrical components from rusting, thereby achieving the purpose of waterproofing and rust prevention.

[0039] 6. The utility model assembles a longitudinal sealing shield on the longitudinal sealing device. When the longitudinal sealing device performs longitudinal sealing, the longitudinal sealing component is relatively close to the material and has a greater impact on the temperature of the material. Therefore, a longitudinal sealing shield is separately arranged here to prevent the escape of water vapor or oil vapor caused by temperature changes.

[0040] 7. The vertical sealing device of the utility model is assembled on the back plate of the electrical box through a slide mounting frame, so that the height adjustment of the vertical sealing device is relatively simple, which is convenient for adjusting the packaging specifications. An opening and closing cylinder is arranged on the protective cover to better control the opening and closing of the protective cover, which is convenient for cleaning operations.

[0041] 8. The utility model also provides a waste film recovery device for recovering waste film edges under the material conveying device, so as to recover the waste film edges cut by the longitudinal sealing device and avoid the waste film edges affecting the packaging process.

[0042] 9. The quick-release feeding tail frame of the utility model also designs the belt conveyor assembly as a quick-release structure. By setting the rotating frame, the distance between the active belt roller and the driven belt roller is changed, thereby changing the tight state or loose state of the conveyor belt, so as to facilitate the disassembly of the conveyor belt and improve the cleaning efficiency of the belt conveyor assembly. A positioning notch is opened on the rotating arm of the rotating frame, and it is fixed by a fixed rotating handle, providing a simple fixed disassembly structure to ensure the stability of the conveyor belt during operation and the quick and convenient disassembly. The position of the driven belt roller can be adjusted by the adjusting screw and the adjusting hole groove at the end of the rotating arm, and the tension of the conveyor belt can be fine-tuned. The convex strips on the conveyor belt and the grooves on the active belt roller and the driven belt roller prevent the conveyor belt from running off during operation.

[0043] 10. The utility model has multiple sets of roller baffle assemblies on the quick-detachable feed tail frame, which can protect the conveyed materials and prevent the materials from deflecting or falling. The roller baffles on both sides of the belt conveyor assembly are designed to be an integrally detachable structure, which can realize the separate disassembly and cleaning of the roller baffle assembly. The roller baffle assembly and the belt conveyor assembly can be cleaned at the same time, thereby improving the overall cleaning efficiency of the belt conveyor.

[0044] 11. The roller baffle assembly of the quick-release feeding tail frame of the utility model can be disassembled and installed by the quick-release handle and the locking knobs on both sides of the support frame. The setting of the adjustment slot is convenient for adjusting the position of the roller baffle assembly relative to the support frame, that is, the spacing between the roller baffle assemblies on both sides of the belt conveyor assembly, so as to adapt to different specifications of conveyed objects. By setting a clearance position and connecting the clearance position with the adjustment slot, the roller baffle assembly can be removed from the support frame or installed on the support frame without removing the locking knob. It can be achieved by simply loosening the locking knob. Adjustment, disassembly and installation can be simple to operate.

[0045] 12. The quick-detachable feed tail frame of the utility model is provided with multiple sets of roller baffle assemblies on both sides of the belt conveyor assembly along the conveying direction of the belt conveyor assembly, and the roller baffle assemblies are made into short-length assembly parts for easy installation, disassembly and transportation, so as to avoid the conveying distance process causing the roller baffle assembly to be large in overall volume, which is not conducive to disassembly. The number of roller baffle assemblies can be adapted and set according to the conveying length of the belt conveyor assembly and the length of a single roller baffle assembly.

[0046] 13. The quick-release feeding tail frame of the utility model has a hollow groove on the back of the baffle frame. When cleaning it, it is easy to discharge dirt through the hollow groove to reduce residue. The adjustment slot on the quick-release handle is scaled to facilitate an intuitive judgment and reference of the position of the roller baffle assembly during adjustment, and to facilitate the spacing adjustment of the roller baffle assemblies on both sides of the belt conveyor assembly. A baffle top cover is set on the baffle frame, and a clamping shaft for clamping the roller is set inside the baffle top cover. After removing the baffle top cover, the roller can be removed separately and cleaned, thereby improving the cleaning rate and cleaning efficiency.

[0047] 14. The transverse sealing device of the utility model has the function of reciprocating translation with the material conveying, which can increase the sealing time and ensure the sealing effect without affecting the packaging conveying efficiency. At the same time, the continuous conveying and sealing of the roll film can be realized without stopping for waiting; at the same time, a detection sensor for detecting the length of the material is set on the quick-detachable feed tail frame. Through the cooperation of the detection sensor and the reciprocating transverse sealing device, the sealing and cutting of the packaging roll film can be automatically realized according to the length of the material, so that the length of the output finished product can be adaptively adjusted according to the length of the material. Belt mounting plates connected to the telescopic belt structures on both sides of the transverse sealing mounting frame are set. The power of the reciprocating translation of the transverse sealing mounting frame is used to drive the telescopic belt to retract, ensuring the docking of the telescopic belt and the transverse sealing device to avoid the situation of package dropping. The utility model can also adjust the height of the translation mounting frame to adapt to changes in packaging specifications.

[0048] 15. The transverse sealing device of the utility model adds film pressing assemblies on both sides of the upper transverse sealing assembly. When the upper transverse sealing assembly cooperates with the lower transverse sealing assembly to seal and cut, the film pressing assembly contacts the roll film before the upper transverse sealing knife holder of the upper transverse sealing assembly, and applies a downward pressure to both ends of the roll film entering between the upper transverse sealing assembly and the lower transverse sealing assembly, so that the roll film between the upper transverse sealing assembly and the lower transverse sealing assembly is tightened and maintains a certain tension, thereby achieving the purpose of neat film cutting. The newly added film pressing assembly has a simple structure and is easy to install. The structure of the film pressing assembly of the utility model is adopted to facilitate the modification of the existing transverse sealing device, and ensure the smoothness of the incision when sealing and cutting the roll film. The film pressing assembly of the utility model includes a film pressing rod and a film pressing mounting plate. The film pressing rod is fixed by the film pressing mounting plate and fixedly assembled with the upper knife holder of the upper transverse sealing assembly; it is simple to assemble and easy to maintain.

[0049] 16. The film pressing mounting plate is provided with a vertical waist-shaped hole, through which the relative position between the film pressing mounting plate and the upper tool holder can be changed, especially the downward extension length of the bottom of the film pressing rod. By changing its installation position, the downward exploration depth of the film pressing rod can be adjusted. The bottom position of the film pressing rod can be adjusted according to different packaging specifications, different film roll materials, etc., to improve the adaptability of the film pressing assembly. A horizontal waist-shaped hole is provided at the bottom of the film pressing mounting plate, through which the installation position of the film pressing rod, that is, the distance between the two film pressing rods, can be changed, so as to adapt to changes in packaging specifications and film roll materials. The film pressing rods on both sides of the upper transverse sealing assembly can be assembled on a set of film pressing mounting plates, which further simplifies the structure of the film pressing assembly and facilitates installation.

[0050] 17. The transverse sealing device of the utility model is separated by a cutter on the upper transverse sealing knife seat and the lower transverse sealing knife seat, with a film-insulating pad on one side and a knife pattern on the other side. The film roll will not be heated on the side with the film-insulating pad, and an opening is formed after cutting; the film roll is heated on the side with the knife pattern, and the heated film roll is pressurized and sealed together under the pressure of the upper transverse sealing knife seat and the lower transverse sealing knife seat to form a single-sided seal. The transverse sealing device of the utility model can meet special packaging needs while ensuring the flatness of the open end of the package after sealing and cutting, thereby improving packaging efficiency.

[0080] As a preferred embodiment of the present invention, refer to the attached specification Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, this embodiment discloses a horizontal packaging machine, including a quick-detachable feeding tail frame 100, a material conveying device 200, a film feeding device 300, a film roll forming device 400, a longitudinal sealing device 500, a transverse sealing device 600 and an electrical box 700, wherein the quick-detachable feeding tail frame 100 is arranged at the input end of the material conveying device 200 and is connected to the material conveying device 200; the film feeding device 300 is arranged below the front end of the material conveying device 200, and the film roll forming device 400 is arranged at the front end of the material conveying device 200; the longitudinal sealing device 500 is arranged above the rear end of the material conveying device 200, and the transverse sealing device 600 is arranged at the output end of the material conveying device 200 and is connected to it; the electrical box 700 is arranged on one side of the material conveying device 200, and the back of the electrical box 700 is equipped with a protective cover 701 which can be opened and closed for covering the longitudinal sealing device 500 and the transverse sealing device 600.

[0081] In this embodiment, a quick-release feeding tail rack 100 is used, which has a quick-release function, so that the feeding tail rack can be cleaned easily, the cleanliness of the feeding tail rack can be ensured, and the hygiene of the materials to be packaged can be ensured, especially for quick-frozen foods, which will have residual water vapor, so it is convenient to clean the residual water vapor to avoid rusting of the equipment; for meat products, there will be some oil residue, and the quick-release feeding tail rack 100 is easy to clean, which improves the cleanliness of the equipment and thus ensures food hygiene. The roll film forming device 400 is arranged at the front end of the material conveying device 200, and the film running device 300 is arranged below the material conveying device 200, that is, the bottom film running method is adopted. After the material to be packaged is output from the feeding tail rack, it can enter the roll film forming device 400. As for the top of the roll film, the direct contact between the material to be packaged and the material conveying device 200 can be avoided, which can effectively ensure the sanitary conditions of the packaged materials.

[0082] The longitudinal sealing device 500 is arranged above the material conveying device 200. On the one hand, it corresponds to the film forming method of the bottom film. On the other hand, since the longitudinal sealing device 500 relies on heat sealing to seal the two sides of the packaging film together, the temperature at the longitudinal sealing device 500 is relatively high. If the top film method is adopted, the high temperature of the longitudinal sealing device 500 has a greater impact on the quick-frozen materials. In this way, the water vapor generated by the temperature change of the quick-frozen food will escape from the bottom, which will cause equipment corrosion for a long time. The present application adopts the bottom film method, combined with the form of the longitudinal sealing device 500 being arranged on the top, the water vapor generated by the quick-frozen food will not leak into the material conveying device 200 and below it, and will not affect the packaging equipment.

[0083] The electrical box 700 is set on one side of the material conveying device 200. On the one hand, the electrical box 700 can provide installation support for the longitudinal sealing device 500. On the other hand, the electrical components are isolated from the material conveying device 200 through the back plate of the electrical box 700 to avoid rust of the electrical components and achieve the purpose of waterproofing and rust prevention.

[0084] A protective cover 701 is provided on the longitudinal sealing device 500 and the transverse sealing device 600. Since both the longitudinal sealing device 500 and the transverse sealing device 600 utilize high-temperature sealing roll film, when quick-frozen or jerky foods pass through the device, some water vapor or oil vapor will be generated due to temperature changes. After the protective cover 701 is provided, the water vapor or oil vapor generated during the packaging process can be prevented from escaping, and the electrical equipment of the packaging machine can be prevented from being corroded and contaminated.

[0085] As an example of this embodiment, the quick-detachable feeding tail frame 100, the material conveying device 200, the film walking device 300, the film roll forming device 400, the longitudinal sealing device 500, the transverse sealing device 600 and the electrical box 700 in this embodiment can all be implemented using existing structures (the existing structures will not be described in detail in this application), and only need to be assembled according to the layout of this embodiment to achieve the technical purpose and effect to be achieved by this application. Among them, the material conveying device 200 can be a belt conveyor or a chain plate conveyor.

Figure 1 and attached Figure 2 As shown, the longitudinal sealing device 500 is fixed on the back of the electrical box 700, and a longitudinal sealing shield 501 is mounted on the longitudinal sealing device 500. Since the longitudinal sealing assembly is relatively close to the material when the longitudinal sealing device 500 performs longitudinal sealing, the temperature of the material is greatly affected, so a longitudinal sealing shield 501 is separately provided here to prevent the escape of water vapor or oil vapor generated by temperature changes.

[0088] Furthermore, the longitudinal sealing device 500 is mounted on the back of the electrical box 700 through a slide mounting frame 502, the slide mounting frame 502 is fixed on the back plate of the electrical box 700, the longitudinal sealing device 500 is slidably mounted on the slide mounting frame 502, and a longitudinal sealing height adjustment component for adjusting the height between the longitudinal sealing device 500 and the material conveying device 200 is provided on the slide mounting frame 502. This makes it relatively simple to adjust the height of the longitudinal sealing device 500, and is convenient for adjusting the packaging specifications. An opening and closing cylinder 702 is provided on the protective cover 701 to better control the opening and closing of the protective cover 701, and facilitate the cleaning operation.

[0089] As an example, the longitudinal seal height adjustment assembly is a screw nut assembly or a gear rack assembly, etc., and any existing technical structure for achieving its height adjustment can be implemented.

[0090] On the basis of the above implementation, it can be further implemented as follows: the electrical box 700 is provided with an opening and closing cylinder 702, one end of the opening and closing cylinder 702 is hinged on the back plate of the electrical box 700, and the other end is hinged to the protective cover 701. The opening and closing of the protective cover 701 can be better controlled to facilitate cleaning operations.

[0091] On the basis of the above embodiment, it can be further implemented as follows: a waste film rewinding device 900 is provided below the rear end of the material conveying device 200, and the waste film rewinding device 900 is configured to recycle the waste film edges cut by the longitudinal sealing device 500, so as to facilitate the recycling of the waste film edges cut by the longitudinal sealing device 500 and avoid the waste film edges affecting the packaging process.

[0092] As an example, the waste film rewinding device 900 can be implemented using an existing structure, such as the waste edge winding device with application number CN202323541294.2, or the film waste edge recovery device with publication number CN219489198U, etc. The specific structure of the waste film rewinding device 900 is not described in detail in this application.

The roller baffle assembly 103 and the belt conveyor assembly 102 can be cleaned at the same time, thereby improving the overall cleaning efficiency of the belt conveyor.

[0105] Furthermore, the roller baffle assembly 103 includes a baffle frame 104 and a plurality of rollers 105 , and the plurality of rollers 105 are rotatably mounted on the baffle frame 104 in parallel along the conveying direction of the belt conveyor assembly 102 ; the quick-release handle 106 is mounted on the baffle frame 104 .

[0122] A preferred solution is to add a detection sensor for detecting the material length, such as a detection electric eye, on the quick-detachable feeding tail frame 100, and connect the detection sensor to the industrial computer of the horizontal packaging machine. Without changing the conveying speed of the material conveying device 200, the reciprocating horizontal sealing device 600 can be used to seal and cut materials of different lengths, thereby finally forming a packaged product that matches the length of the material.

[0128] As another preferred embodiment of the present utility model, this embodiment further supplements and elaborates on the technical solution of the present utility model on the basis of the above-mentioned embodiments 1, 2, 3, 4, 5, 6 and 7.

[0129] Refer to the instruction manual Fig.14 , Attachment Fig.18 , Attachment Fig.19 , Attachment Fig. 20 , Attachment Fig.21 and attached Fig. 22 As shown, the implementation scheme of this embodiment is: the transverse sealing mechanism of the transverse sealing device 600 includes an upper transverse sealing component 601, a lower transverse sealing component 602, a transverse sealing mounting frame 616, and a transverse sealing driving component that drives the upper transverse sealing component 601 and the lower transverse sealing component 602 to move relative to each other to perform sealing and cutting actions; the upper transverse sealing component 601 and the lower transverse sealing component 602 are both slidably assembled on the transverse sealing mounting frame 616, the transverse sealing driving component is assembled on the transverse sealing mounting frame 616, and the transverse sealing driving component realizes the engagement or separation of the upper transverse sealing component 601 and the lower transverse sealing component 602 through the transmission of the transmission component.

[0130] Specifically, the upper transverse sealing assembly 601 is assembled on the upper tool holder 612, and the lower transverse sealing assembly 602 is assembled on the lower tool holder 613. The transverse sealing driving assembly drives the upper tool holder 612 and the lower tool holder 613 to move closer to or away from each other through the transmission of the transmission assembly.

[0131] Example 9

[0132] As another preferred embodiment of the utility model, this embodiment is based on the above-mentioned embodiment 8, and this embodiment provides an improved implementation scheme of the transverse sealing device 600, which can be applied to both the reciprocating transverse sealing device 600 and the fixed transverse sealing device 600. The transverse sealing device 600 provided in this implementation scheme can achieve neat sealing cuts of the transverse sealing device 600, thereby ensuring the appearance of the finished packaged product.

[0133] For details, please refer to the attached manual. Fig.15 , Attachment Fig.16 and attached Fig.17 As shown, film pressing assemblies 605 are arranged on both sides of the upper transverse sealing knife seat 603 of the upper transverse sealing assembly 601; when the upper transverse sealing assembly 601 and the lower transverse sealing assembly 602 are driven to engage with each other by the transverse sealing driving assembly, the film pressing assembly 605 moves downward with the upper transverse sealing assembly 601, and the bottom end surface of the film pressing assembly 605 is lower than the bottom end surface of the upper transverse sealing knife seat 603 of the upper transverse sealing assembly 601, so that the film pressing assembly 605 contacts the roll film before the upper transverse sealing knife seat 603, so as to maintain the tension of the roll film during the process of the upper transverse sealing assembly 601 and the lower transverse sealing assembly 602 engaging to seal and cut the film.

[0134] As an implementation method of this embodiment, refer to the attached Fig.14 , Attachment Fig.16 and attached Fig.17 As shown, the film pressing assembly 605 includes a film pressing rod 610 and a film pressing mounting plate 611. The film pressing mounting plate 611 is provided with two pieces, which are respectively mounted on the two ends of the upper knife holder 612 for mounting the upper horizontal sealing knife holder 603 in the upper horizontal sealing assembly 601; the two ends of the film pressing rod 610 are respectively mounted on the two film pressing mounting plates 611. In this embodiment, a cylindrical film pressing rod 610 is used for film pressing, which is conducive to the arc transition between the film pressing rod 610 and the film roll, and avoids the film pressing parts with edges and corners from damaging the film roll during the process of film pressing. At the same time, such a structural method is relatively easy to adjust and saves the cost of parts.

[0135] The upper end of the film pressing mounting plate 611 is fixed to the upper tool holder 612 by connecting bolts, and a vertical waist-shaped hole 614 is provided on the film pressing mounting plate 611 at a position corresponding to the connecting bolts; the end of the film pressing rod 610 is fixedly assembled on the film pressing mounting plate 611 by nuts, and a horizontal waist-shaped hole 615 is provided on the film pressing mounting plate 611 at a position corresponding to the end of the film pressing rod 610. Through the vertical waist-shaped hole 614, the relative position between the film pressing mounting plate 611 and the upper tool holder 612, especially the length of the bottom of the film pressing rod 610 extending downward, can be changed. By changing its installation position, the downward depth of the film pressing rod 610 can be adjusted. The bottom position of the film pressing rod 610 can be adjusted according to different packaging specifications, different film roll materials, etc., to improve the adaptability of the film pressing assembly 605. Through the horizontal waist-shaped hole 615, the installation position of the film pressing rod 610, that is, the spacing between the two film pressing rods 610 can be changed, so as to adapt to changes in packaging specifications and film roll materials.

[0136] As another example of this embodiment, the film pressing rods 610 on both sides of the upper transverse sealing assembly 601 can be assembled on a set of film pressing mounting plates 611 to further simplify the structure of the film pressing assembly 605 and facilitate installation.

[0137] As another way of this embodiment, not shown in the figure, downwardly extending film pressing members can be provided on both sides of the upper transverse sealing assembly 601, which can also play the role of film pressing, such as an inverted "L"-shaped plate, but compared with the film pressing rod 610 structure in the above embodiment, this L-shaped plate has lower adjustable flexibility and uses more materials.

This embodiment provides an implementation scheme of an improved transverse sealing device 600, which can be applied to both a reciprocating transverse sealing device 600 and a fixed transverse sealing device 600. The transverse sealing device 600 provided in this implementation scheme can realize a packaged product with one end sealed and the other end not sealed, which is convenient for the subsequent vacuuming operation of the opened packaged product.

[0140] In this embodiment, refer to the attached manual Fig.15 and attached Fig.16 As shown, the upper horizontal sealing knife seat 603 of the upper horizontal sealing component 601 and the lower horizontal sealing knife seat 604 of the lower horizontal sealing component 602 are separated by the cutter 607.
