Description
Technical Field
[0001] This application relates to the field of sealing equipment technology, and in particular to a sealing machine housing structure and a sealing machine having the sealing machine housing structure. Background Technology
[0002] After loading the product, to ensure product quality and prevent leakage, the packaging container needs to be sealed. With the development of automation technology, this process is usually completed by specialized sealing machinery. A sealing machine is a type of mechanical equipment specifically designed to seal packaging containers containing goods. With the continuous development of packaging technology, sealing machines play a crucial role in the production of film sealing packaging in industries such as food, pharmaceuticals, and daily chemicals.
[0003] A sealing machine typically includes a machine body, an unwinding drum, a winding drum, and a hot-pressing and cutting device. The hot-pressing and cutting device is mounted on the machine body, while the unwinding drum and winding drum are located on opposite sides of the hot-pressing and cutting device. The sealing film roll is fitted onto the unwinding drum, and after passing through the hot-pressing and cutting device, the sealing film is wound onto the winding drum. The sealing film seals the packaging container through the hot-pressing elements and cutting elements in the hot-pressing and cutting device. Then, the waste sealing film is wound and recycled through the winding drum.
[0004] To improve the safety of sealing machines and ensure cleanliness and hygiene, current sealing machines generally adopt a fully enclosed sidewall design to enhance dustproof performance. This means that the hot-pressing elements and cutting elements in the hot-press film cutting device are enclosed within the sealing machine's casing structure, achieving a dustproof rating of IP54. When repairing or replacing parts such as the cutting blade, it is necessary to remove the front panel and left and right side panels. The front panel is typically fixed with 6-8 M4 screws, making disassembly and reassembly cumbersome and time-consuming. With the diversification of packaging materials, the wear cycle of the cutting blade has decreased from 2 million cycles to 500,000 cycles, significantly increasing the replacement frequency. Traditional structures require the complete removal of the front panel for each replacement, taking an average of 15 minutes, severely impacting production efficiency and reducing capacity by an average of 12% to 18%.
[0005] In related technologies, to address the inconvenience of disassembling and assembling the cutter, one solution involves setting 200×150mm access ports on the left and right side panels, using dust covers attracted by neodymium iron boron magnets to conceal the access ports. While this makes opening and closing relatively convenient, the magnets easily attract metal debris, leading to seal failure, and the seal lifespan is less than 3 months in dusty environments. Another solution uses a sliding drawer structure to install the cutter assembly, facilitating the removal of the entire cutter assembly from the sealing machine housing for disassembly and assembly. However, the sliding rails are prone to trapping packaging debris and other foreign objects, causing blockages and jamming, and maintenance is also inconvenient. Utility Model Content
[0006] To improve the ease of changing the cutter of a sealing machine and ensure the stable and reliable operation of the sealing machine, this application provides a sealing machine housing structure and a sealing machine having the sealing machine housing structure.
[0007] Firstly, the sealing machine housing structure of the sealing machine provided in this application adopts the following technical solution:
[0008] A sealing machine housing structure includes a front panel, a left side panel, and a right side panel; the left side panel is provided with a left cover for covering the sealing film strip, and the right side panel is provided with a right cover for covering the sealing film strip.
[0009] The lower side of the front panel has a notch, and a front baffle is provided at the notch; the upper two ends of the front baffle are respectively hinged to the left side panel and the right side panel.
[0010] The left side panel has a left opening; the left cover has a first door opening opposite the left opening, and the left cover has a left door panel for closing the first door opening and being openable and closable; the right side panel has a right opening; the right cover has a second door opening opposite the right opening, and the right cover has a right door panel for closing the second door opening and being openable and closable.
[0011] The fixing screws for the cutter and cutter holder are located on the front and left / right sides, typically two screws on each of these three sides. By adopting the above technical solution, the original sealed sidewall structure of the sealing machine casing is eliminated. A hinged, swingable front baffle is installed at the notch on the lower side of the front panel, and an openable left door panel is installed on the left cover, and an openable right door panel is installed on the right cover. This allows operators to easily open the front baffle, left door panel, and right door panel when changing the cutter, facilitating the removal of the various fixing screws. This avoids the cumbersome cutter replacement operation caused by the traditional sealed sidewall, greatly improving cutter replacement efficiency, saving change time, and increasing production efficiency. After the cutter is replaced, closing the left and right door panels and lowering the front baffle ensures dust prevention and safety.
[0012] Optionally, the upper side of the front baffle is bent twice to form a first flange and a second flange respectively. When the front baffle is in a vertical state, the first flange extends toward the inside of the front panel, and the second flange extends upward. When the front baffle swings upward to a horizontal state, the lower side of the front panel abuts against the outside of the second flange.
[0013] By adopting the above technical solution, the stability and sealing of the connection between the front baffle and the front panel can be enhanced, which is beneficial to maintaining the internal environment of the chassis. At the same time, it facilitates the swinging operation of the front baffle, which is conducive to the cutting tool replacement operation and improves the tool replacement efficiency. Moreover, the above structure realizes the limitation of the front panel on the upward swing of the front baffle, effectively preventing the front baffle from swinging excessively and failing to return to its original position under its own gravity; thus improving its stability and reliability in use.
[0014] Optionally, both ends of the second flange are provided with connecting ears that fold outward toward the second flange; the connecting ears are provided with connecting holes for inserting connecting pins; the front baffle is hinged to the left side plate and the right side plate by the connecting pins.
[0015] By adopting the above technical solution, the front baffle is easy to install and can swing flexibly. When changing the cutter, the operator can more easily approach the cutter installation position. At the same time, this hinge structure is stable and reliable, which helps to improve the convenience and time efficiency of the cutter replacement operation.
[0016] Optionally, one side of the left door panel is connected to the left cover via a first pivot, and the other side of the left door panel is provided with a first latch for locking the left door panel to the left cover; one side of the right door panel is connected to the right cover via a second pivot, and the other side of the right door panel is provided with a second latch for locking the right door panel to the right cover.
[0017] By adopting the above technical solution, the left and right door panels can be opened and closed easily, while ensuring a stable connection between the left and right door panels when closed, which helps to maintain the internal environment of the chassis.
[0018] Optionally, the upper and front sides of the left cover have a first enclosure portion that bends toward the left side plate and is fixed to the left side plate, and the upper first enclosure portion has a first through hole that runs vertically through the left and right sides for the sealing film strip to pass through; the upper and front sides of the right cover have a second enclosure portion that bends toward the right side plate and is fixed to the right side plate, and the upper second enclosure portion has a second through hole that runs vertically through the right and right sides for the sealing film strip to pass through.
[0019] By adopting the above technical solution, a specific travel path can be provided for the sealing film material belt, ensuring stable conveying of the sealing film material belt, thereby ensuring that the sealing machine can continuously and effectively perform sealing operations during operation.
[0020] Optionally, the planar area of the left door panel is larger than the cross-sectional area of the first door opening, and the inner four perimeters of the left door panel are provided with sealing strips that can abut against the outer side of the left cover; the planar area of the right door panel is larger than the cross-sectional area of the second door opening, and the inner four perimeters of the right door panel are also provided with sealing strips that can abut against the outer side of the right cover.
[0021] By adopting the above technical solution, the left and right door panels can abut against the outer sides of the left and right covers when closed, which enhances the sealing of the chassis and does not affect the opening and closing of the left and right door panels. This ensures both the convenience of blade replacement and the protection of the chassis interior.
[0022] Optionally, the sealing machine housing structure further includes a top plate; the top plate, left side plate, right side plate, left cover and right cover are integrally stamped; the top of the left cover and right cover is lower than the height of the top plate; the upper side and left and right sides of the front panel have inwardly bent edges, and the edges are fixedly connected to the top plate, left side plate and right side plate by connectors.
[0023] By adopting the above technical solution, the integrated stamping of the top plate, left side plate, right side plate, left cover and right cover simplifies the manufacturing process and improves the structural strength and integrity; the top of the left cover and right cover is lower than the height of the top plate, which optimizes the spatial layout; the folded edges on the upper left and right sides of the front plate are fixedly connected to the top plate, left side plate and right side plate through connectors, ensuring the stability of the connection between the front panel and other components, making the sealing machine box structure more robust and reliable.
[0024] Secondly, the sealing machine provided in this application adopts the following technical solution:
[0025] A sealing machine includes the sealing machine housing structure described above.
[0026] By adopting the above technical solution, when changing the blade of the sealing machine, the left and right door panels can be opened, and the fixing screws of the cutter can be directly accessed using the notch on the lower side of the front panel and the swingable front baffle. This effectively solves the problem of cumbersome blade replacement operation caused by the traditional closed side wall, greatly improves blade replacement efficiency, saves blade replacement time, and improves work efficiency.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. In this application, a hinged and swingable front baffle is provided at the notch on the lower side of the front panel, a left door panel that can be opened and closed is provided on the left cover, and a right door panel that can be opened and closed is provided on the right cover, which facilitates the removal and installation of the fixing screws of the cutter. This effectively solves the problem of cumbersome cutter replacement operation caused by traditional closed sidewalls, greatly improves the cutter replacement efficiency, saves cutter replacement time, and improves work efficiency.
[0029] 2. In this application, the first and second flange structures of the front baffle play a supporting and limiting role in different states, which helps to maintain structural stability.
[0030] 3. This application guarantees the stability and reliability of the overall structural connection. Attached Figure Description

[0038] The following will be combined with the appendix Figure 1 -Appendix Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.
[0039] This application primarily adopts a design that modifies the sealed sidewall structure of the sealing machine to an openable door, thereby achieving rapid blade replacement and improving blade replacement efficiency. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, the sealing machine provided in this embodiment includes a machine body 15, an unwinding drum 16, a take-up drum 17, and a hot-press film cutting device. The machine body 15 is provided with a sealing machine housing structure. The hot-press film cutting device is located inside the sealing machine housing structure. The unwinding drum 16 and the take-up drum 17 are respectively located on the upper sides of the sealing machine housing structure. The sealing film roll is sleeved on the unwinding drum 16. After the sealing film strip passes through the hot-press film cutting device, it is wound around the take-up drum 17. The sealing film performs a sealing operation on the packaging container through the hot-pressing element and the cutting element in the hot-press film cutting device. Then, the sealing film waste strip is wound and recycled through the take-up drum 17.
[0040] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the sealing machine housing structure includes a front panel 1, a left side panel 2, a right side panel 3, and a top panel 14; the left side panel 2 has a left cover 4 for covering the sealing film strip on its outer side, and the right side panel 3 has a right cover 5 for covering the sealing film strip on its outer side; a notch 100 is opened on the lower side of the front panel 1, and a front baffle 6 is provided at the notch 100; the upper ends of the front baffle 6 are respectively hinged to the left side panel 2 and the right side panel 3; a left opening 21 is opened on the left side panel 2; a first door opening 41 is opened on the left cover 4 facing the left opening 21, and a left door panel 7 for closing the first door opening 41 and being able to open and close is provided on the left cover 4; a right opening 31 is opened on the right side panel 3; a second door opening 51 is opened on the right cover 5 facing the right opening 31, and a right door panel 8 for closing the second door opening 51 and being able to open and close is provided on the right cover 5.
[0041] Furthermore, refer to Figure 5As shown, the upper side of the front baffle 6 is bent twice to form a first flange 61 and a second flange 62. When the front baffle 6 is in a vertical state, the first flange 61 extends towards the inside of the front panel 1, and the second flange 62 extends upward. When the front baffle 6 swings upward to a horizontal state, the lower side of the front panel 1 abuts against the outside of the second flange 62. Both ends of the second flange 62 are provided with connecting ears 63 that fold outward towards the second flange 62. The connecting ears 63 are provided with connecting holes 631 for inserting connecting pins 9. The front baffle 6 is hinged to the left side panel 2 and the right side panel 3 by connecting pins 9. This enhances the stability and sealing of the connection between the front baffle 6 and the front panel 1, which is beneficial for maintaining the internal environment of the chassis. It also facilitates the swinging operation of the front baffle 6, which is conducive to the operation of cutting tool replacement and improves the efficiency of tool replacement. Moreover, the above structure realizes the limitation of the front panel 1 on the upward swing of the front baffle 6, effectively preventing the front baffle 6 from swinging excessively and failing to return to its original position by its own gravity; thus improving its stability and reliability in use.
[0042] Reference Figure 4 and Figure 5 As shown, one side of the left door panel 7 is connected to the left cover 4 via a first pivot 10, and the other side of the left door panel 7 is provided with a first latch 12 for locking the left door panel 7 to the left cover 4; one side of the right door panel 8 is connected to the right cover 5 via a second pivot 11, and the other side of the right door panel 8 is provided with a second latch 13 for locking the right door panel 8 to the right cover 5. The upper and front sides of the left cover 4 have a first enclosure portion 42 that bends toward the left panel 2 and is fixed to the left panel 2, and the upper first enclosure portion 42 has a first through hole 421 that passes through vertically for the sealing film strip to pass through; the upper and front sides of the right cover 5 have a second enclosure portion 52 that bends toward the right panel 3 and is fixed to the right panel 3, and the upper second enclosure portion 52 has a second through hole 521 that passes through vertically for the sealing film strip to pass through. The first through hole 421 and the second through hole 521 provide a specific path for the sealing film strip, ensuring stable conveying of the sealing film strip, and thus ensuring that the sealing machine can continuously and effectively perform sealing operations during operation.
[0043] In this embodiment, the planar area of the left door panel 7 is larger than the cross-sectional area of the first door opening 41, and the inner four perimeters of the left door panel 7 are provided with sealing strips that can abut against the outer side of the left cover 4; the planar area of the right door panel 8 is larger than the cross-sectional area of the second door opening 51, and the inner four perimeters of the right door panel 8 are also provided with sealing strips that can abut against the outer side of the right cover 5. This allows the left door panel 7 and the right door panel 8 to abut against the outer sides of the left cover 4 and the right cover 5 when closed, enhancing the airtightness of the chassis, while not affecting the opening and closing of the left door panel 7 and the right door panel 8, ensuring both the convenience of blade replacement and the protection effect inside the chassis.
[0044] In this embodiment, the top plate 14, left side plate 2, right side plate 3, left cover 4, and right cover 5 are integrally stamped; the top of the left cover 4 and right cover 5 is lower than the height of the top plate 14; the upper side and left and right sides of the front panel 1 have inwardly bent folded edges 110, and the folded edges 110 are fixedly connected to the top plate 14, left side plate 2, and right side plate 3 by connecting parts, which can be bolts or rivets.
[0045] The implementation principle is as follows: The fixing screws 19 of the cutter 18 and the cutter holder are located on the front and left and right sides, respectively, usually two fixing screws 19 on each of these three sides; in this embodiment, the side wall enclosure structure of the original sealing machine box is eliminated, and a hinged and swingable front baffle 6 is set at the notch 100 on the lower side of the front panel 1, a left door panel 7 that can be opened and closed is set on the left cover 4, and a right door panel 8 that can be opened and closed is set on the right cover 5. This allows the operator to easily open the front baffle 6, left door panel 7 and right door panel 8 when changing the cutter, so as to easily remove the various fixing screws 19 of the cutter. This avoids the cumbersome cutter replacement operation caused by the traditional closed side wall, greatly improves the cutter replacement efficiency, saves the cutter replacement time, and improves production efficiency. After the cutter is replaced, the left door panel 7 and right door panel 8 are closed, and the front baffle 6 is lowered to ensure dust prevention and safety.
[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
