Description
Technical Field
[0001] This utility model relates to the field of vacuum technology, and in particular to a vacuum mechanism and packaging equipment. Background Technology
[0002] Vacuuming is often required for packaging materials such as food. Traditional vacuuming methods include tube-type vacuuming and vacuum chamber-type vacuuming. Typically, a vacuuming actuator is set up at a single fixed station. The packaging container is transported to the station where the vacuuming actuator is located for vacuuming, and then the packaging container leaves the station and is removed. To ensure the vacuuming effect, a sufficiently long vacuuming time is required. However, the long time consumed by a single station will cause other processes to wait for too long, resulting in an excessively long overall processing time and seriously affecting processing efficiency. Furthermore, a mobile vacuuming method has been developed. The vacuuming actuator is configured to be movable, and a gas distribution guide rail is set along the moving path of the vacuuming actuator. Several air holes for vacuuming are set at intervals along the length of the gas distribution guide rail. The vacuuming actuator is connected to a mating part for moving along the gas distribution guide rail. When the vacuuming actuator moves to the mating part and connects with the air hole, the vacuuming actuator performs vacuuming operation for a period of time. Then the vacuuming actuator continues to move. When the vacuuming actuator moves to the mating part and connects with the next air hole, the vacuuming actuator performs vacuuming operation for another period of time. This changes the traditional single-station vacuuming method to a multi-station mobile vacuuming method, which shortens the vacuuming time of a single station and thus effectively improves the overall processing efficiency. Moreover, the vacuuming actuator does not separate from the packaging container during the entire vacuuming process, thus ensuring the vacuuming effect. However, the gas distribution guide rail only covers a section of the moving path of the vacuum actuator. As a result, the mating parts switch from a state of separation from the gas distribution guide rail to a state of engagement with the gas distribution guide rail. Since the mating parts need to fit effectively with the gas distribution guide rail to ensure sealing during movement, the required fitting accuracy between the mating parts and the gas distribution guide rail is relatively high. The current technology's component processing accuracy and assembly accuracy are difficult to meet the requirements, which can easily lead to interference and collision between the mating parts and the gas distribution guide rail. This can affect the operation of the equipment, easily cause damage to the mating parts and the gas distribution guide rail, and thus affect the fitting accuracy and the vacuuming effect. Utility Model Content
[0003] The technical problem to be solved and the technical task proposed by this utility model is to improve the existing technology and provide a vacuum pumping mechanism to solve the problem that in the current mobile vacuum pumping method, the mating parts and the gas distribution guide rail are prone to collision, which leads to damage to the mating parts and the gas distribution guide rail and affects normal operation.
[0004] To solve the above technical problems, the technical solution of this utility model is as follows:
[0005] A vacuuming mechanism includes a mating component and a gas distribution guide rail. The gas distribution guide rail has a plurality of air holes spaced apart along its path direction. The mating component has a venting channel for communicating with the air holes. The mating component has a mating surface for fitting against the gas distribution guide rail surface to travel along the gas distribution guide rail. The mating surface has a venting inlet for the venting channel.
[0006] The two ends of the air distribution guide rail are respectively connected to transition rails. There is a preset height difference of 1 between the rail surface of the transition rail and the rail surface of the air distribution guide rail. The mating component is provided with guide wheels for traveling along the transition rail. There is a preset height difference of 2 between the traveling surface formed by the guide wheels and the contact surface. The preset height difference 1 is equal to the preset height difference 2.
[0007] The vacuuming mechanism described in this utility model features guide wheels on the mating component to engage with the transition rail at the end of the gas distribution guide rail. These guide wheels can roll, allowing the mating component to smoothly enter and exit the transition rail, effectively reducing or avoiding impacts and improving smoothness. Furthermore, when the mating component enters the transition rail, the contact surface precisely reaches the height required to mate with the surface of the gas distribution guide rail. As the mating component continues to enter the gas distribution guide rail, the contact surface precisely mates with the rail surface, ensuring a smooth and precise entry into the gas distribution guide rail. This effectively avoids impacts, prevents component damage, ensures long-term stable operation of the equipment, and reliably performs vacuuming operations.
[0008] Furthermore, the end of the transition rail is also provided with a guide ramp section inclined to the rail surface, which makes the mating parts enter the transition rail more smoothly and better avoids impact.
[0009] Furthermore, the transition rail includes tracks respectively provided on both sides of the valve distribution guide rail path direction. When the mating component is on the transition rail, the guide wheel travels along the track; when the mating component is on the valve distribution guide rail, the guide wheel is located on both sides of the valve distribution guide rail path direction. The guide wheel only plays a traveling role when the mating component is on the transition rail; when the mating component is on the valve distribution guide rail, the guide wheel is in a non-working suspended state, which does not affect the tightness of the fit between the mating surface and the valve distribution guide rail surface.
[0010] Furthermore, the mating component includes a base and a movable part. The bottom surface of the base is provided with the mating surface. A flexible tube connects the base and the movable part. Cavities are provided on the base and the movable part to communicate with the flexible tube, forming the ventilation channel. The movable part is provided with the ventilation outlet of the ventilation channel. The mating component is a connecting part used to connect a movable vacuuming actuator. It is difficult to maintain a high-precision consistency between the movement path of the vacuuming actuator and the path of the gas distribution guide rail. Therefore, the mating component flexibly adapts to the changes in the distance between the vacuuming actuator and the gas distribution guide rail. The base and the movable part can move relative to each other through the flexible tube while ensuring the airway connectivity. During the movement of the vacuuming actuator, the mating component can stably maintain a tight fit with the gas distribution guide rail, thereby ensuring the reliability of vacuuming.
[0011] Furthermore, an elastic element is provided between the base and the movable part, so that the base and the movable part can float elastically, can be elastically reset, and flexibly adapt to the changes in the distance between the vacuum actuator and the gas distribution guide rail.
[0012] Furthermore, several elastic elements are spaced apart on the circumference of the flexible tube to provide uniform elastic support, prevent the flexible tube from being damaged by excessive force, ensure the long-term stable operation of the flexible tube, and extend its service life.
[0013] Furthermore, the contact surface is made of a smooth and wear-resistant material to ensure that the contact surface can fully and tightly contact the surface of the air distribution guide rail, maintain good sealing performance, thereby ensuring the reliability of vacuuming, low frictional resistance, which helps to reduce drive power consumption, good wear resistance, and long service life.
[0014] Furthermore, the bonding surface is detachably connected to the base, making it easy to maintain and replace.
[0015] A packaging device includes the aforementioned vacuuming mechanism, a conveying mechanism, and a clamping mechanism for fixing packaging containers. The clamping mechanism is driven by the conveying mechanism. A gas distribution guide rail is arranged along the conveying direction of the conveying mechanism and is connected to a vacuum generator. A mating component is connected to the clamping mechanism, which is equipped with a vacuuming execution mechanism. The venting channel of the mating component communicates with the vacuuming execution mechanism to perform vacuuming operations on the packaging containers. The packaging device of this invention enables mobile vacuuming, allowing for vacuuming at multiple workstations. The vacuuming time at a single workstation is short, improving overall processing efficiency. More importantly, the mating component and the gas distribution guide rail cooperate more smoothly, effectively avoiding impacts and component damage, ensuring long-term stable operation of the equipment, and reliably performing vacuuming operations.
[0016] Furthermore, the vacuuming actuator is a vacuum chamber or a vacuum suction tube for inserting into the packaging container. It can be applied to different types of vacuuming methods as needed, offering good flexibility and applicability.
[0017] Compared with the prior art, the advantages of this utility model are:
[0018] The vacuuming mechanism and packaging equipment described in this utility model enable mobile vacuuming. The mating parts can smoothly connect and cooperate with the gas distribution guide rail, effectively avoiding collisions and impacts, ensuring stable equipment operation, ensuring long-term stable vacuuming operation, and ensuring vacuuming efficiency and effect.

Detailed Implementation
[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0033] The present invention discloses a vacuuming mechanism and packaging equipment in which the mating parts can smoothly ride on the gas distribution guide rail, effectively avoiding impact, ensuring the integrity of the mating parts and the gas distribution guide rail, ensuring long-term stable operation of vacuuming, and ensuring vacuuming effect.
[0034] like Figure 1As shown, a vacuuming mechanism mainly includes a mating component 1 and a gas distribution guide rail 2. The gas distribution guide rail 2 has a plurality of air holes 21 spaced apart along its path direction on its surface. The gas distribution guide rail 2 is connected to a vacuum generating device (not shown in the figure), meaning that the vacuum generating device is connected to the air holes 21 on the gas distribution guide rail 2 to draw air through the air holes 21 to generate a negative pressure vacuum. The mating component 1 is provided with a vent for communicating with the air holes 21, and the mating component 1 is provided with a fitting surface for conforming to the gas distribution guide rail 2 to move along the gas distribution guide rail 2. The contact surface 14 is provided with the air inlet 15 of the air passage. The mating part 1 is used to connect with the vacuuming actuator. Specifically, the air outlet 16 of the air passage on the mating part 1 is connected to the vacuuming actuator. When the mating part 1 moves along the air distribution guide 2 to the air inlet 15 of the mating part 1 and connects with the air hole 21 of the air distribution guide 2, the vacuuming actuator is connected to the vacuum generating device through the air passage, and thus the vacuuming actuator can perform the vacuuming operation. In this embodiment, the vacuuming mechanism adopts a mobile vacuuming method. The mating component 1 moves with the vacuuming actuator. When the air passage of the mating component 1 is directly connected to the air hole 21, the vacuuming actuator stops moving. The valve at the air hole 21 opens and performs a vacuuming operation for a preset time. After that, the valve at the air hole 21 closes, and the vacuuming actuator moves again. Due to the vacuum adsorption effect, the mating component 1 is tightly attached to the surface of the gas distribution guide rail 2 through the mating surface 14. No vacuum breakage will occur during the process of the mating component 1 moving along the gas distribution guide rail 2 to the next air hole. In the empty state, the vacuum actuator will maintain its current vacuum level while moving. When the vacuum actuator moves to the point where the air passage of the mating part 1 is directly connected to the next air hole 21, the valve at the next air hole 21 will open and perform the vacuum operation again for a preset time before closing. This process is repeated to perform multi-station mobile vacuuming. The vacuuming time of each station is short, which makes the dynamic and static time ratio of the production line more reasonable, thereby effectively improving the overall processing efficiency and vacuuming efficiency and effect, and meeting the application requirements of high vacuum.
[0035] Furthermore, such as Figures 2 to 5As shown, in order to make the movement of the mating component 1 into and out of the air distribution guide rail 2 smoother and avoid collisions and impacts that could affect equipment operation and damage components, transition rails 22 are respectively connected to the inlet and outlet ends of the air distribution guide rail 2. Specifically, there is a preset height difference I between the rail surface of the transition rail 22 and the rail surface of the air distribution guide rail 2. The mating component 1 is provided with guide wheels 17 for traveling along the transition rail 22. There is a preset height difference II between the traveling surface formed by the guide wheels 17 (the traveling surface formed by the guide wheels 17 refers to the plane where the lowest point of the wheel rim of all the guide wheels is located) and the contact surface 14. The preset height difference I is equal to the preset height difference II. The guide wheel 17 rolls forward, allowing the mating part 1 to smoothly enter or exit the transition rail 22. This effectively reduces or avoids impacts, improves smoothness, and when the mating part 1 enters the transition rail 22, the guide wheel 17 is in contact with the rail surface of the transition rail 22. That is, the traveling surface formed by the guide wheel 17 and the rail surface of the transition rail 22 are on the same plane. At this time, the contact surface 14 is exactly at the same height as the rail surface of the air distribution guide rail 2. Thus, when the mating part 1 travels along the transition rail 22 to the air distribution guide rail 2, the contact surface 14 can accurately contact the rail surface of the air distribution guide rail 2 without impact. This allows the mating part 1 to smoothly and accurately enter the air distribution guide rail 2, effectively avoiding impacts, preventing damage to components, ensuring long-term stable operation of the equipment, and ensuring reliable vacuuming operations. Furthermore, from a height perspective, specifically, the transition rail 22 can be positioned at a height lower than the valve guide rail 2, with the corresponding travel surface formed by the guide rollers 17 being lower than the contact surface 14; or the transition rail 22 can be positioned at a height higher than the valve guide rail 2, with the corresponding travel surface formed by the guide rollers 17 being higher than the contact surface 14. The preset height difference one and preset height difference two are within the range of 0.3–1 mm, which helps to ensure that the mating part 1 can more precisely and smoothly achieve a tight fit with the valve guide rail 2.
[0036] More specifically, such as Figure 1 As shown, the transition rail 22 includes tracks respectively set on both sides of the path direction of the gas distribution guide rail 2. When the mating component 1 is on the transition rail 22, the guide wheel 17 travels along the track. When the mating component 1 is on the gas distribution guide rail 2, the guide wheel 17 is located on both sides of the path direction of the gas distribution guide rail 2. In other words, the guide wheel 17 is set on both sides of the traveling direction of the mating component 1, and the distance between the guide wheels 17 on both sides of the mating component 1 is greater than the width of the rail surface of the gas distribution guide rail 2. Therefore, when the mating component 1 is on the gas distribution guide rail 2, the guide wheel 17 will not contact the gas distribution guide rail 2, ensuring that the contact surface 14 can fully and effectively fit tightly with the rail surface of the gas distribution guide rail 2, ensuring good airtightness, and thus ensuring the reliability of vacuuming. Furthermore, there is a hollow area between the two tracks of the transition rail 22 to avoid the contact surface 14 of the mating component 1, which can better ensure that the contact surface 14 accurately fits and contacts the rail surface of the gas distribution guide rail 2 when the mating component 1 enters the gas distribution guide rail 2.
[0037] Furthermore, such as Figure 2 As shown, a guide ramp 221 inclined to the rail surface of the transition rail 22 is also provided at the end of the transition rail 22. When the mating part 1 drives onto the transition rail 22, the guide wheel 17 of the mating part 1 first contacts the guide ramp 221. The guide ramp 221 is inclined at a small angle relative to the travel path of the guide wheel 17, which has good smooth transition and makes the mating part 1 drive into the transition rail 22 more smoothly, thus better avoiding collision impact.
[0038] The mating component 1 is used to connect the movable vacuuming actuator. The movement path of the vacuuming actuator is difficult to keep perfectly parallel to the path of the gas distribution guide rail. Therefore, during the movement of the vacuuming actuator, the distance between the vacuuming actuator and the gas distribution guide rail fluctuates. To ensure the reliability of vacuuming and avoid vacuum breakage due to these distance changes, the mating component 1 adopts a movable structure to flexibly adapt to the changes in the distance between the vacuuming actuator and the gas distribution guide rail. Specifically, as shown... Figures 6 to 9 As shown, the mating component 1 includes a base 11 and a movable part 12. The bottom surface of the base 11 is provided with a contact surface 14. A flexible tube 13 connects the base 11 and the movable part 12. Cavities are provided on the base 11 and the movable part 12 to communicate with the flexible tube 13 to form the ventilation channel. The contact surface 14 is provided with an air inlet 15 of the ventilation channel, and the movable part 12 is provided with an air outlet 16 of the ventilation channel. Thus, the base 11 and the movable part 12 can move relative to each other through the flexible tube 13 to form an air passage with a variable length, while always ensuring the connectivity and external sealing of the air passage. This ensures that the vacuuming actuator can reliably connect with the gas distribution guide rail 2 through the mating component 1 to form a stable air passage during movement, thereby ensuring the reliability of vacuuming. Multiple air outlets 16 of the ventilation channel can be provided on the movable part 12 to increase the flow area and allow for multi-point air extraction, which is beneficial for more efficient vacuuming.
[0039] Furthermore, an elastic element 18 is provided between the base 11 and the movable part 12. Specifically, several elastic elements 18 are provided, which can be springs, and are evenly distributed around the circumference of the flexible tube 13. This allows the base and the movable part to float elastically, enabling them to return to their original position and flexibly adapt to changes in the distance between the vacuum actuator and the gas distribution guide rail. It also protects the flexible tube 13, preventing excessive force from being applied to it when the base 11 and the movable part 12 move relative to each other, thus ensuring the long-term stability of the flexible tube 13 and its function as a gas path. To ensure sealing and connection stability, flanges are provided at both ends of the flexible tube 13, and the ends of the flexible tube 13 are connected to the base 11 and the movable part 12 through the flanges. Preferably, the flexible tube 13 is a corrugated pipe, which has a stable structure, high strength, and can undergo elastic expansion and contraction deformation, making it less prone to breakage. Furthermore, the movable part 12 is slidably engaged with the base 11, and a guide mechanism is provided between the movable part 12 and the base 11. Specifically, a protrusion is provided on the edge of the base 11, and guide strips are provided on both sides of the protrusion on the movable part 12. A guide groove is formed between the two guide strips. The protrusion slides along the guide groove to limit and guide the relative movement of the movable part 12 and the base 11. The structure is simple and easy to implement, making the relative movement between the movable part 12 and the base 11 more stable. In this embodiment, the flexible tube 13 is a relatively short pipe. The relative sliding direction of the movable part 12 and the base 11 defined by the guide mechanism is along the axial direction of the flexible tube 13, thereby avoiding unnecessary lateral impact force on the flexible tube 13 and ensuring that the mating parts can stably and reliably form a gas passage for vacuuming.
[0040] Furthermore, the contact surface 14 is made of a smooth and wear-resistant material, such as polytetrafluoroethylene or polyurethane, to ensure that the contact surface can fully and tightly contact the surface of the air distribution guide rail, maintaining good sealing performance, thereby ensuring the reliability of vacuuming. It also features low frictional resistance, which helps reduce drive power consumption, good wear resistance, and a long service life. In addition, the contact surface 14 is detachably connected to the base 11. As the contact surface 14 is a consumable part, it will wear after prolonged sliding contact with the air distribution guide rail 2. The detachable connection structure facilitates maintenance and replacement. Specifically, the contact surface 14 is provided with several connection holes, and screws are used to connect the contact surface 14 to the base 11, ensuring a tight and stable connection while facilitating replacement.
[0041] like Figure 10As shown, a packaging device includes the aforementioned vacuuming mechanism, a conveying mechanism 3, and a clamping mechanism 4 for fixing the packaging container. In this embodiment, the packaging container mainly refers to a packaging bag. The packaging bag is clamped and fixed by a clamp provided on the clamping mechanism 4. The clamping mechanism 4 is driven by the conveying mechanism 3, which can be a ring guide rail, chain, synchronous belt, or other specific conveying device. The gas distribution guide rail 2 is arranged along the conveying direction of the conveying mechanism 3 and is connected to a vacuum generating device (not shown in the figure). A mating part 1 is connected to the clamping mechanism 4, and a vacuuming execution mechanism is provided on the clamping mechanism 4. The air passage of the mating part 1 is connected to the vacuuming execution mechanism to perform vacuuming operations on the packaging container. The clamping mechanism 4 is driven by the conveying mechanism 3. The mating component 1 moves along with the clamping mechanism 4. When the mating component 1 mounts the air distribution guide rail 2 and its air inlet 15 is directly connected to the air hole 21 of the air distribution guide rail 2, the conveying mechanism 3 stops, the clamping mechanism 4 stops at its current position, and the valve of the air hole 21 opens to allow the vacuuming actuator to vacuum the packaging bag. After a preset time for vacuuming, the valve of the air hole 21 closes, and the conveying mechanism 3 resumes operation to drive the clamping mechanism 4 to continue moving. When the air inlet 15 of the mating component 1 is directly connected to the next air hole 21, the valve of the next air hole 21 opens to allow the vacuuming actuator to vacuum the packaging bag. Vacuuming is performed on the bag, and this process is repeated to perform multi-station mobile vacuuming. The vacuuming time at each station is short, which can improve the overall processing efficiency. As the clamping mechanism 4 moves from the position of the previous air hole 21 to the position of the next air hole 21, the mating surface 14 of the mating part 1 is fully and tightly attached to the rail surface of the gas distribution guide 2. Due to the negative pressure adsorption, the rail surface of the gas distribution guide 2 blocks the air inlet 15 on the mating surface 14, so that the vacuuming actuator and the packaging bag maintain their current vacuum state. When the bag reaches the position of the next air hole 21, the vacuuming operation continues, which effectively ensures the reliability of vacuuming.
[0042] More specifically, such as Figure 10 and Figure 11 As shown, the vacuum actuator can be a vacuum chamber 51. Figure 10 The image shows the lower chamber of vacuum chamber 51. The packaging bag and clamps for securing the packaging bag are located within the lower chamber. The upper chamber is closable and fastened to the lower chamber. Specifically, the upper chamber can be flip-openable and closable, connected to the lower chamber, and its opening and closing is driven by a power mechanism. Figure 11As shown, a circulating conveying mechanism is set above the conveying mechanism 3. The upper chamber is conveyed through the circulating conveying mechanism. When the upper chamber moves to the lower position, it engages with the lower chamber. The upper and lower chambers together form a vacuum chamber 51. The ventilation channel of the mating part 1 is connected to the vacuum chamber 51, thereby performing a vacuuming operation on the packaging bag located in the vacuum chamber 51. In addition, the vacuuming actuator can also be a vacuuming suction tube for inserting into the packaging bag. The ventilation channel of the mating part 1 is connected to the vacuuming suction tube to vacuum the packaging bag. Preferably, the vacuuming suction tube can be movably mounted on the clamping mechanism 4. The vacuuming suction tube switches between a first position inserted into the packaging bag and a second position withdrawn from the packaging bag. When the vacuuming suction tube is switched to the first position, the vacuuming suction tube is connected to the ventilation channel of the mating part 1, thereby performing a vacuuming operation on the packaging bag.
[0043] Preferably, such as Figure 10 As shown, several clamps are connected in parallel on the clamping mechanism 4, so that several packaging bags can be placed in parallel on the clamping mechanism 4, and multiple packaging bags can be vacuumed at the same time, which effectively improves the overall processing efficiency and greatly increases the production capacity.
[0044] Furthermore, the aforementioned packaging equipment can specifically be equipment primarily performing vacuuming. This means that the packaged bags containing materials are transferred from the preceding equipment to the clamping mechanism 4 for clamping and fixing, then the packaging bags are vacuumed, and finally heat-sealed or pre-heat-sealed at the last station before being transferred to the next processing equipment. Alternatively, the packaging equipment can also include bagging and filling processes. This means that bagging mechanisms and filling mechanisms are sequentially arranged along the conveying path of the conveying mechanism 3. Unfilled packaging bags are placed onto the clamps of the clamping mechanism 4 via the bagging mechanism, and then materials are filled into the packaging bags via the filling mechanism. A multi-station moving vacuuming process is then performed by the vacuuming mechanism, and finally, the packaging bags are heat-sealed to obtain the final product.
[0045] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
