Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tea packaging machinery, concretely relates to a vacuum heat seal integrated device. BACKGROUND

[0002] In the processing and packaging process of tea, in order to ensure the freshness and quality of tea during long-term storage and transportation, the tea bag is usually vacuumized and heat sealed after the tea is loaded into the tea bag. The vacuumizing process aims to remove the air in the tea bag to reduce the oxidation rate of tea and prolong its shelf life. The heat sealing process ensures the sealing of the tea bag to prevent the intrusion of external air, moisture and microorganisms, thereby maintaining the original flavor and aroma of the tea.

[0003] The tea packaging machines on the market generally adopt the design of combining vacuumizing mechanism and heat sealing mechanism, and the opening and closing actions of the vacuum chamber and the sealing action of the tea bag mouth by the heat sealing cutter head are controlled by two independent driving mechanisms. This design ensures the independence of operation to a certain extent, but also brings the problem of high driving cost.

[0004] In order to reduce production cost and improve equipment efficiency, the prior art provides a vacuum heat sealing device, two cutter heads of the heat sealing mechanism of the device are fixed in two vacuum chambers of the vacuumizing mechanism, so that the device can drive the two cutter heads of the heat sealing mechanism to approach each other, clamp and seal the bag mouth of the tea bag, so that the heat sealing mechanism can heat seal the bag mouth of the tea bag by driving the two vacuum chambers to close at the same time by one driving mechanism. This design significantly reduces the driving cost and improves the overall efficiency and stability of the equipment, but still has certain limitations in actual application.

[0005] Specifically, since the two cutter heads of the heat sealing mechanism are fixed in the two vacuum chambers, and the installation position of the cutter head may have a certain degree of error, and the thickness of the bag mouth of different tea bags may also differ, these factors may cause the two cutter heads to not completely seal the entire bag mouth of the tea bag when closing, or may cause the two cutter heads to seal the bag mouth of the tea bag too tightly. Among them, the sealing is not tight enough may cause the tea bag to leak air during storage and transportation, thereby affecting the freshness and quality of the tea, and the sealing is too tight may affect the subsequent vacuumizing effect, causing air to remain in the bag, which is also not conducive to the long-term preservation of the tea.

[0006] Therefore, how to improve the existing vacuum heat sealing device has become a technical problem to be solved in the field of tea packaging machinery. UTILITY MODEL CONTENTS

[0044] 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.

[0045] This utility model provides a vacuum heat sealing integrated device 1, which solves the problem of how to simultaneously control the opening and closing action of the vacuum chamber 14 and the sealing action of the heat sealing mechanism 3 through a single drive mechanism 4, and ensure the effectiveness of vacuuming and heat sealing.

[0046] See Figure 1 As shown, Figure 1 The figure shows a perspective view of the vacuum heat sealing integrated device in the embodiment. The vacuum heat sealing integrated device 1 includes a vacuum pumping mechanism 1, a bag receiving frame 2, a heat sealing mechanism 3, and a driving mechanism 4.

[0047] The vacuum pumping mechanism 1 includes a fixed body 11, a movable body 12, and a vacuum pump 13. The movable body 12 is slidably connected to the fixed body 11 along a first direction, which is perpendicular to the vertical direction. Both the fixed body 11 and the movable body 12 have vacuum chambers 14. The vacuum pump 13 is connected to one of the vacuum chambers 14 and is used to evacuate the closed cavity formed by the two vacuum chambers 14.

[0048] The bag receiving rack 2 is located between the two vacuum chambers 14. The bag receiving rack 2 has a placement slot 21 for receiving tea bags filled with tea leaves.

[0049] Combination Figure 2 and Figure 3 As shown, Figure 2 This is a partial structural diagram of the fixing body and heat sealing mechanism in the embodiment. Figure 3This is a partial structural diagram of the movable body and heat-sealing mechanism in the embodiment. The heat-sealing mechanism 3 is used to seal the tea bag after vacuuming. The heat-sealing mechanism 3 includes a first cutter head 31 and a second cutter head 32 arranged opposite to each other. The first cutter head 31 is fixed in the vacuum chamber 14 of the fixed body 11 by welding or screwing, etc., and the second cutter head 32 is slidably connected to the vacuum chamber 14 of the movable body 12 along a first direction.

[0050] The drive mechanism 4 is mounted within the fixed body 11 by welding or screwing. The drive mechanism 4 is connected to the movable body 12 and also to the second cutter head 32 via an elastic component 5. The elastic component 5 exerts a force that drives the second cutter head 32 toward the first cutter head 31. The drive mechanism 4 drives the movable body 12 and the second cutter head 32 to slide together toward or away from the vacuum chamber 14 of the fixed body 11.

[0051] When using the vacuum heat-sealing integrated device described above, firstly, the tea bag is placed in the placement slot 21 of the bag receiving frame 2. Then, the driving mechanism 4 drives the movable body 12 and the second cutter head 32 to slide together toward the vacuum chamber 14 of the fixed body 11, closing the two vacuum chambers 14 to form a sealed cavity. Simultaneously, the second cutter head 32 and the first cutter head 31 cooperate to clamp and seal the opening of the tea bag. Then, the vacuum pump 13 is started to evacuate the sealed cavity, thus achieving vacuuming of the tea bag. After vacuuming, the heat-sealing mechanism 3 heat-seals the opening of the tea bag using the first cutter head 31 and the second cutter head 32. Finally, the driving mechanism 4 drives the movable body 12 and the second cutter head 32 to move away from the vacuum chamber 14 of the fixed body 11, releasing the tea bag so that the vacuum-sealed tea bag can be transferred to the next process. As can be seen, this utility model can simultaneously realize the opening and closing of two vacuum chambers 14 and the clamping and sealing of the tea bag opening by the heat sealing mechanism 3 through a single drive mechanism 4, greatly saving drive costs. Furthermore, the drive mechanism 4 drives the second cutter head 32 and the first cutter head 31 to approach each other and clamp the tea bag opening through the elastic component 5. The elastic component 5 has a force that drives the second cutter head 32 towards the first cutter head 31. This not only ensures that the first cutter head 31 and the second cutter head 32 can completely seal the entire tea bag opening when the mold is closed, but also prevents the first cutter head 31 and the second cutter head 32 from sealing the tea bag opening too tightly, thus effectively ensuring the vacuuming and heat sealing effects.

[0052] The aforementioned bag receiving rack 2 not only receives the tea bags filled with tea, but also restricts the shape of the tea bags through the shape of the placement groove 21, playing a shaping role. After shaping, vacuum heat sealing can effectively ensure the consistency and aesthetics of the shape of the tea bags after vacuum heat sealing.

[0053] In this embodiment, the fixed body 11 is provided with a guide rod 111 extending along the first direction, and both the upper and lower ends of the movable body 12 are slidably connected to the fixed body 11 through the guide rod 111. In this way, the stability of the movable body 12 during the sliding process can be ensured.

[0054] See Figure 3 , Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the fixed body, movable body, and drive mechanism in the embodiment. Figure 5 This is a bottom view of the fixed body, movable body, and drive mechanism in one embodiment. In one implementation of the drive mechanism 4, the drive mechanism 4 includes a rotary drive component 41, a turntable 42, a first slide block 43, and a second slide block 44. The rotary drive component 41 is fixed within the fixed body 11 by welding or screwing and is connected to the turntable 42 in a transmission manner. Linkage blocks 421 are eccentrically connected to both the upper and lower sides of the turntable 42. The first slide block 43 and the second slide block 44 are slidably connected within the fixed body 11 along a first direction. The first slide block 43 is connected to the movable body 12. The second slide block 44 is connected to the second cutter head 32 via an elastic component 5. The first slide block 43 and the second slide block 44 are also slidably connected to two linkage blocks 421 along a second direction, with the second direction, the first direction, and the vertical direction being mutually perpendicular. The rotary drive component 41 drives the turntable 42 to rotate, and the turntable 42 drives the first slide block 43 and the second slide block 44 to slide together along the first direction via the linkage blocks 421. Thus, when the rotary drive 41 drives the turntable 42 to rotate, the two linkage blocks 421 rotate around the axis of the turntable 42. The rotational stroke can be decomposed into a sliding stroke along the first direction and a sliding stroke along the second direction. The sliding stroke of the linkage block 421 along the first direction can drive the two first slide blocks 43 to slide along the first direction, thereby driving the movable body 12 and the second cutter head 32 to slide together along the first direction, so as to simultaneously realize the opening and closing action of the two vacuum chambers 14 and the clamping and sealing action of the heat sealing mechanism 3 on the mouth of the tea bag.

[0055] The aforementioned turntable 42 can use an existing gear disk, and the rotary drive component 41 can use an existing servo motor or other rotary drive mechanism 4. The output end of the servo motor is provided with a drive gear 411 by means of welding or coupling, etc. The drive gear 411 meshes with the gear disk. In this way, when the servo motor drives the drive gear 411 to rotate, the drive gear 411 can drive the turntable 42 to rotate.

[0056] Both the first slide block 43 and the second slide block 44 have a sliding channel 431 extending in the second direction. The linkage block 421 is located in the sliding channel 431. Thus, both the first slide block 43 and the second slide block 44 can be slidably connected to the linkage block 421 in the second direction through the sliding channel 431.

[0057] See Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of the elastic component 5, the elastic component 5 includes a push rod 51 and an elastic element 52. The push rod 51 is slidably connected to the movable body 12 along a first direction. One end of the push rod 51 is fixedly connected to the second cutter head 32 by welding or screwing. Both ends of the elastic element 52 are respectively connected to the second slide block 44 and the other end of the push rod 51. The elastic element 52 is used to drive the push rod 51 and the second cutter head 32 to move towards the first cutter head 31 along the first direction. Thus, when the turntable 42 drives the second slide block 44 to slide towards the first cutter head 31 in the first direction via the linkage block 421, the second slide block 44 drives the elastic component 5 and the second cutter head 32 to move together towards the first cutter head 31 until the two vacuum chambers 14 close. Then, the elastic component 52 drives the push rod 51 and the second cutter head 32 to continue moving towards the first cutter head 31 in the first direction, so that the second cutter head 32 and the first cutter head 31 tightly clamp the mouth of the tea bag, ensuring that the entire mouth of the tea bag is completely sealed, thereby effectively ensuring the heat sealing effect of the vacuum heat sealing device. When the vacuum pump 13 draws a vacuum, the air inside the tea bag pushes the second cutter head 32 to move away from the first cutter head 31 and compresses the elastic component 52, thereby moving it out of the tea bag. This effectively avoids the situation where residual air in the bag occurs due to the first cutter head 31 and the second cutter head 32 sealing the mouth of the tea bag too tightly, thereby effectively ensuring the vacuum drawing effect of the vacuum heat sealing device.

[0058] The aforementioned elastic element 52 can be made from existing components with elastic force, such as compression springs.

[0059] See Figure 1 and Figure 2 As shown, based on any of the above embodiments, a docking groove 15 is provided on the outer side of the vacuuming mechanism 1. The docking groove 15 docks with the placement groove 21. Both the docking groove 15 and the placement groove 21 are U-shaped and extend in the same direction. The vacuum heat-sealing integrated device also includes an ejection mechanism 6. The ejection mechanism 6 is installed on one side of the vacuuming mechanism 1 and is used to eject the tea bag in the placement groove 21 along the extension direction of the placement groove 21 to the docking groove 15. In this way, after the vacuuming and heat-sealing process is completed, the vacuum heat-sealing integrated device can eject the vacuumed and heat-sealed tea bag out of the vacuuming mechanism 1 through the ejection mechanism 6, which facilitates the subsequent manual or mechanical removal of the tea bag for packaging, and also facilitates the placement of the next tea bag to be vacuum heat-sealed into the placement groove 21. In this embodiment, the placement groove 21 extends in a second direction.

[0060] See Figure 1 and Figure 2As shown, based on the above embodiment, the heat-sealing mechanism 3 and the ejection mechanism 6 are arranged vertically. The bag receiving frame 2 is movably positioned between the two vacuum chambers 14 in the vertical direction. The vacuum heat-sealing integrated device also includes a bag receiving frame drive mechanism 7. The bag receiving frame drive mechanism 7 is mounted on the fixed body 11 by welding or screwing and is connected to the bag receiving frame 2 in a transmission manner. The bag receiving frame drive mechanism 7 is used to drive the bag receiving frame 2 to move in the vertical direction so that the bag receiving frame 2 is positioned opposite the heat-sealing mechanism 3 or the ejection mechanism 6. Thus, to avoid interference between the ejection mechanism 6 and the heat sealing mechanism 3, the ejection mechanism 6 and the heat sealing mechanism 3 may be staggered in the vertical direction. In this case, when the vacuum heat sealing integrated device is used, firstly, the bag receiving frame drive mechanism 7 drives the bag receiving frame 2 to rise to the position opposite to the heat sealing mechanism 3, so that the tea bag containing tea can be received and shaped through the placement groove 21 for subsequent vacuuming and heat sealing. After the vacuuming and heat sealing are completed, the drive mechanism 4 drives the movable body 12 and the second cutter head 32 to return to their original positions and release the tea bag. Then, the bag receiving frame drive mechanism 7 drives the bag receiving frame 2 to fall to the position opposite to the ejection mechanism 6, so that the docking groove 15 docks with the placement groove 21, so that the ejection mechanism 6 can eject the tea bag in the placement groove 21 out of the vacuuming mechanism 1.

[0061] The bag receiving frame drive mechanism 7 described above can use existing servo motors and gear racks to drive the bag receiving frame 2 to move up and down.

[0062] See Figure 2 As shown, in one embodiment of the ejection mechanism 6, the ejection mechanism 6 includes a push plate 61 and a push plate drive assembly 62. The push plate 61 is located on one side between the two vacuum chambers 14. The push plate drive assembly 62 is mounted on one side of the vacuuming mechanism 1 and is drively connected to the push plate 61. The push plate drive assembly 62 is used to drive the push plate 61 to move along the extension direction of the placement groove 21. Thus, when the docking groove 15 docks with the placement groove 21, the push plate drive assembly 62 drives the push plate 61 to move along the extension direction of the placement groove 21 into the middle of the two vacuum chambers 14, thereby pushing the tea bag in the placement groove 21 into the docking groove 15 outside the vacuuming mechanism 1.

[0063] The aforementioned pusher drive assembly 62 can drive the pusher 61 to linear displacement using existing servo motors and gear racks.

[0064] See Figure 1 , Figure 2 and Figure 3As shown, based on any of the above embodiments, the vacuum heat sealing integrated device further includes a leveling mechanism 8. The leveling mechanism 8 is installed below the heat sealing mechanism 3 and includes a lifting drive component 81 and two clamping arms 82. The two clamping arms 82 are slidably connected vertically within the two vacuum chambers 14, and are vertically fixedly connected. The lifting drive component 81 is mounted on the vacuuming mechanism 1 by welding or screwing, and is drively connected to one of the clamping arms 82. The lifting drive component 81 is used to drive the two clamping arms 82 to move up and down. Thus, the drive mechanism 4 drives the movable body 12 and the second cutter head 32 to slide together toward the vacuum chamber 14 of the fixed body 11. When the two vacuum chambers 14 are closed, the second cutter head 32 and the first cutter head 31 cooperate to clamp the opening of the tea bag, while the two clamping arms 82 correspondingly clamp the upper part of the tea bag. Then, the lifting drive component 81 drives the two clamping arms 82 to move up and down synchronously, which can make the upper part of the tea bag flat, further shaping the tea bag and facilitating the heat sealing of the upper opening. In this embodiment, the two clamping arms 82 are slidably connected along the first direction by a slide rod 83 and fixedly connected along the vertical direction. The slide rod 83 extends along the first direction.

[0065] The aforementioned lifting drive component 81 can use existing servo motors and gear racks to drive the lifting motion of the clamping arm 82.

[0066] See Figure 3 and Figure 5 As shown, the clamping arm 82 has a flat recess 821 in the middle. The flat recesses 821 of the two clamping arms 82 cooperate to restrict the upper part of the tea bag between the two flat recesses 821, and the shape of the two flat recesses 821 is used to shape the tea bag.

[0067] 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.
