Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, and in particular to a sealing film mechanism for a sealing machine. Background Technology

[0002] Driven by the wave of consumption upgrading, commercial sealing machines are no longer limited to commercial scenarios. With the popularization of the fast-paced lifestyle and the surge in consumer demand for personalized and convenient beverages, commercial sealing machines are accelerating their penetration into homes and small shops. With its efficient and precise sealing technology, it can quickly seal the cups of freshly made beverages such as milk tea and coffee.

[0003] However, while common sealing machines used in the beverage industry can quickly seal cups, they require pressing the film down to ensure full contact with the cup rim. During this pressing process, the film is prone to deformation, causing it to loosen. This affects subsequent sealing. Furthermore, common sealing machines have limited sealing efficiency, requiring sealed cups to be removed before the next cup can be placed, making it impossible to quickly seal large batches of cups. Therefore, this application proposes a sealing mechanism for a sealing machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing mechanism for a sealing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing machine sealing mechanism includes a main body, which is composed of a lower horizontal section and an upper vertical section. The vertical section of the main body is installed at the middle of its top. A movable frame is provided between the horizontal sections of the main body. Two cup holders symmetrically distributed on the top of the movable frame are fixedly installed. A lifting plate is provided at the bottom of each cup holder. A heat-sealing film section is installed between the vertical sections of the main body. Rotatable take-up rollers and unwind rollers are respectively provided at the left and right ends of the top of the vertical section of the main body. Limiting shafts are installed between the front and rear sides of the vertical section of the main body and on both sides at the top of the heat-sealing film section. Adjustment components are provided between the front and rear sides of the vertical section of the main body and on both sides at the bottom of the heat-sealing film section. A control panel is installed on the front side of the vertical section of the main body.

[0006] Optionally, the width of the horizontal part of the main body is three times the width of the vertical part, and the front and rear sides of the horizontal part of the main body are provided with first slots. The middle part of the first slot is horizontal, and the left and right ends of the first slot are inclined upwards. The front and rear sides of the moving frame are provided with two sets of second slots. Each set of second slots is located on both sides of the corresponding lifting plate. The bottom of the two lifting plates is equipped with a fixing rod, and both ends of the fixing rod pass through the corresponding second slot and extend into the first slots on both sides of the main body. Both ends of the fixing rod are rotatably fitted with rollers located in the first and second slots.

[0007] Optionally, each of the four corners of the two lifting plates has a through hole running vertically through it, and each of the four corners of the bottom of the two cup holders has a positioning rod that passes through and is inserted into the corresponding through hole.

[0008] Optionally, a storage slot is provided at the corner of the top of the vertical part of the main body. The two ends of the take-up roller are respectively located in the two storage slots on the left end, and the two ends of the unwind roller are respectively located in the two storage slots on the right end. A limit component is provided on the inner wall of each storage slot. A motor is installed at the left end of the top rear side of the vertical part of the main body. The output end of the motor extends into the corresponding storage slot. The output end of the motor is set as a flat insert plate. A groove adapted to the insert plate is provided at the end of the take-up roller near the motor. The groove at the end of the take-up roller can be fitted into the insert plate at the output end of the motor.

[0009] Optionally, the limiting assembly includes a limiting plate and a first spring. The inner side of the storage slot has a plate groove, and a through-hole extending to the top of the main body is opened at the center of the top of the plate groove. The limiting plate is L-shaped, with the vertical part of the limiting plate located in the through-hole and the horizontal part of the limiting plate located in the plate groove. The horizontal end of the limiting plate can extend into the storage slot and abut against the top of both ends of the take-up roller and the unwind roller. The first spring is fixedly connected between the inner end of the plate groove and the vertical part of the limiting plate.

[0010] Optionally, the adjustment assembly includes a rotating shaft, a bearing seat, and a second spring. A third slot is provided on both the front and rear sides of the vertical part of the main body where the adjustment assembly is connected. A bearing seat is movably installed in each third slot. The two ends of the rotating shaft are respectively fixedly inserted into the corresponding bearing seats. A second spring is fixedly connected between the third slot and the corresponding bearing seat. The horizontal height of the bottom of the adjustment assembly is higher than the horizontal height of the top of the cup holder.

[0011] Optionally, a movable groove is provided at the top of the inner wall of the main body's horizontal section, and a rod groove is provided at the right end of the movable groove. A hydraulic rod is fixedly installed in the rod groove. A fixed block located in the movable groove is fixedly installed at the bottom left of the movable frame. The telescopic end of the hydraulic rod extends into the movable groove and connects with the fixed block. Ball grooves are provided at the four corners of the bottom of the movable frame. A rotatable ball is provided in each ball groove. The bottom end of each ball extends out of the ball groove and contacts the bottom of the inner wall of the main body.

[0012] The beneficial effects of this utility model are:

[0013] When the sealing film is pressed down to seal the cup opening, the tension generated by the downward movement of the sealing film will drive the rotating shafts in the two adjustment components to move. This causes the bearing seat at the end of the rotating shaft to slide in the third groove and squeeze the second spring in the third groove. The elastic deformation of the second spring can buffer the external force on the sealing film, and the mutual approach of the two rotating shafts can also prevent the sealing film from being squeezed and deformed and loosened. After sealing is completed, as the external force disappears, the second spring releases the stored elastic potential energy and pushes the bearing seat to return to its original position. This adjustable dynamic balance design effectively avoids deformation of the sealing film due to excessive local force, ensuring that the sealing film between the take-up roller and the unwind roller always remains taut, providing a stable material supply for subsequent sealing operations.

[0014] The moving frame adopts a unique dual-station alternating design: when the left half of the moving frame descends to below the vertical part of the main body and performs sealing operations on the cups in the left cup tray, its right half is exactly outside the vertical part of the main body. At this time, the operator can simultaneously place the cup to be sealed on the right cup tray. After the sealing on the left is completed, the moving frame switches stations through lateral displacement to immediately seal the cups on the right. At the same time, the sealed cups on the left can be taken out. This "operating while preparing materials" cyclical working mode completely breaks through the efficiency bottleneck of "picking and placing while waiting" in traditional single-station sealing machines, realizes continuous and parallel processing of beverages, and greatly improves the sealing capacity per unit time.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figures 1-9 This utility model provides a technical solution: a sealing machine sealing mechanism, including a main body 1, which is composed of a lower horizontal part and an upper vertical part. The vertical part of the main body 1 is installed at the middle position of its top. A movable frame 2 is provided between the horizontal parts of the main body 1. Two cup holders 3 are fixedly installed on the top of the movable frame 2 and are symmetrically distributed. A lifting plate 32 is provided at the bottom of each cup holder 3. A heat sealing film part 12 is installed between the vertical parts of the main body 1. A rotatable take-up roller 5 and a unwinding roller 4 are respectively provided at the left and right ends of the top of the vertical part of the main body 1. Limiting shafts 8 are installed between the front and rear sides of the vertical part of the main body 1 and on both sides at the top of the heat sealing film part 12. Adjustment components 9 are provided between the front and rear sides of the vertical part of the main body 1 and on both sides at the bottom of the heat sealing film part 12. A control panel 13 is installed on the front side of the vertical part of the main body 1.

[0028] like Figure 1 and Figure 2As shown, the width of the horizontal part of the main body 1 is three times the width of the vertical part, and the front and rear sides of the horizontal part of the main body 1 are provided with first slots 11. The middle part of the first slot 11 is horizontal, and the left and right ends of the first slot 11 are inclined upward. The front and rear sides of the moving frame 2 are provided with two sets of second slots 21. Each set of second slots 21 is located on both sides of the corresponding lifting plate 32. The bottom of the two lifting plates 32 is equipped with a fixing rod 33, and both ends of the fixing rod 33 pass through the corresponding second slot 21 and extend into the first slots 11 on both sides of the main body 1. Both ends of the fixing rod 33 are rotatably sleeved with rollers 34 located in the first slot 11 and the second slot 21.

[0029] When the left half of the moving frame 2 is below the vertical part of the main body 1 and is sealing the cups in the cup holder 3, the right half of the moving frame 2 is outside the vertical part of the main body 1. At this time, the cup to be sealed can be placed in the cup holder 3 on the right. By moving the moving frame 2 left and right, the cups in the two cup holders 3 can be sealed alternately. Compared with the sealing method of common sealing machines, the sealing efficiency of the cups is higher. Furthermore, when the moving frame 2 moves to the left, the lifting plate 32 at the bottom of the left cup holder 3 moves along with it due to the constraint of the positioning rod 31. The rollers 34 at both ends of the bottom fixing rod 33 of the lifting plate 32 will move to the left in the first slot 11. When the rollers 34 move to the inclined part on the left side of the first slot 11, the rollers 34 and the fixing rod 33 will gradually move to the upper left, and the fixing rod 33 will move vertically upward in the second slot 21 outside the moving frame 2, thereby driving the lifting plate 32 to move along the direction of the positioning rod 31. This will push out the sealed cup in the left cup holder 3. The rightward movement of the moving frame 2 is the same as the left side, and can lift the sealed cup in the right cup holder 3.

[0030] like Figure 1 and Figure 2 As shown, each of the four corners of the two lifting plates 32 has a through hole that runs vertically through them. Each of the four corners of the bottom of the two cup holders 3 is equipped with a positioning rod 31 that is inserted into the corresponding through hole. By the insertion and cooperation of the positioning rod 31 with the through hole on the lifting plate 32, the lifting plate 32 can always be kept in a horizontal state, and the lifting plate 32 can be raised and lowered vertically.

[0031] like Figure 4 and Figure 7As shown, a storage slot 14 is provided at the corner of the top of the vertical part of the main body 1. The two ends of the take-up roller 5 are respectively located in the two storage slots 14 on the left end, and the two ends of the unwind roller 4 are respectively located in the two storage slots 14 on the right end. A limit component 7 is provided on the inner wall of each storage slot 14. A motor 6 is installed at the left end of the top rear side of the vertical part of the main body 1. The output end of the motor 6 extends into the corresponding storage slot 14, and the output end of the motor 6 is set as a flat insert plate 61. A groove 51 adapted to the insert plate 61 is provided at the end of the take-up roller 5 near the motor 6. The groove 51 at the end of the take-up roller 5 can be fitted into the insert plate 61 at the output end of the motor 6. When placing the take-up roller 5, the groove 51 at the end of the take-up roller 5 is aligned with the insert plate 61 on the output end of the motor 6. Through the insertion and cooperation of the two, the motor 6 can drive the take-up roller 5 to wind up the sealing film.

[0032] like Figure 4 and Figure 5 As shown, the limiting assembly 7 includes a limiting plate 72 and a first spring 73. A groove is formed on the inner side of the storage slot 14, and an opening 71 extending to the top of the main body 1 is formed at the center of the top of the groove. The limiting plate 72 is L-shaped, with its vertical portion located within the opening 71 and its horizontal portion located within the groove. The horizontal end of the limiting plate 72 can extend into the storage slot 14 and abut against the tops of both ends of the take-up roller 5 and the unwind roller 4. The first spring 73 is fixedly connected to the groove. Between the inner end of the limit plate 72 and the vertical part of the limit plate 72, the vertical part of the limit plate 72 is moved within the opening 71 by moving the limit plate 72. This allows the horizontal part of the limit plate 72 to move into the slot, thereby enabling the replacement of the take-up roller 5 and the unwind roller 4 in the storage slot 14. Under the action of the first spring 73, the limit plate 72 can be reset, so that the limit plate 72 can block the upper ends of the take-up roller 5 and the unwind roller 4, preventing the take-up roller 5 and the unwind roller 4 from leaving the storage slot 14.

[0033] like Figure 4 and Figure 6As shown, the adjusting assembly 9 includes a rotating shaft 91, a bearing seat 92, and a second spring 93. A third slot is provided on both the front and rear sides of the vertical part of the main body 1 where it connects to the adjusting assembly 9. A bearing seat 92 is movably installed in each third slot. Both ends of the rotating shaft 91 are fixedly inserted into the corresponding bearing seat 92. A second spring 93 is fixedly connected between the third slot and the corresponding bearing seat 92. The bottom of the adjusting assembly 9 is at a higher horizontal height than the top of the cup holder 3. When the sealing film is pressed down to close the cup, the downward movement of the sealing film pulls the two adjusting assemblies... The rotating shaft 91 in component 9 causes the bearing seats 92 at the ends of the two rotating shafts 91 to move within the third slot and compress the second spring 93 within the third slot. After sealing, the sealing film is no longer compressed by external force, and the external force on the adjusting component 9 also disappears. At this time, the second spring 93 will release its elasticity to push the bearing seat 92 back to its original position. By adjusting the movable adjustment of the adjusting component 9, the sealing film can be prevented from deforming under pressure, so that the sealing film between the take-up roller 5 and the unwind roller 4 will not become loose, which is convenient for subsequent continued use.

[0034] like Figure 8 and Figure 9 As shown, a movable groove 15 is provided at the top of the inner wall of the horizontal section of the main body 1. A rod groove is provided at the right end of the movable groove 15. A hydraulic rod 16 is fixedly installed in the rod groove. A fixed block 22 located in the movable groove 15 is fixedly installed at the left position of the bottom of the movable frame 2. The telescopic end of the hydraulic rod 16 extends into the movable groove 15 and connects with the fixed block 22. Ball grooves are provided at the four corners of the bottom of the movable frame 2. Rotatable balls 23 are provided in each ball groove. The bottom end of each ball 23 extends out of the ball groove and contacts the bottom of the inner wall of the main body 1. By controlling the extension and retraction of the hydraulic rod 16, the fixed block 22 can be moved in the movable groove 15, thereby enabling the movable frame 2 to move left and right between the horizontal sections of the main body 1. This allows the two cup holders 3 inside the movable frame 2 to move in and out left and right. Furthermore, the four balls 23 at the bottom of the movable frame 2 can reduce the contact area between its bottom and the main body 1, thereby reducing the friction between the two and making the movable frame 2 easier to move.

[0035] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
