Description

Technical Field

[0001] This utility model relates to the field of vacuum technology, specifically to an automatic vacuum conveying device. Background Technology

[0002] A vacuum is a physical phenomenon in which the gas pressure in a given space is lower than one atmosphere.

[0003] In the existing technology, vacuum technology plays an indispensable role in many fields of society today. Whether it is the electronics industry or food packaging, the need for a vacuum environment is ubiquitous. The commonly used equipment for vacuum packaging is the nozzle-type sealing machine, which can quickly vacuum seal packaging bags, and the vacuum sealing effect is highly stable, making it suitable for batch vacuum sealing of packing straps.

[0004] However, existing nozzle-type vacuum sealing machines are manually operated. Not only do they require manually placing the nozzle into the bag to be vacuumed and straightening the bag to ensure a smooth and wrinkle-free seal, but they also require manually controlling the vacuum button to perform the vacuuming process, which seriously affects production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic vacuum conveying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic vacuum conveying device, the automatic vacuum conveying device comprising:

[0007] A conveyor belt, a vacuum machine body is fixed to the side surface of the conveyor belt, a lower sealing rod is fixed to the surface of the vacuum machine body, the lower sealing rod is parallel and attached to the upper surface of the conveyor belt, an upper sealing rod is movably disposed on the surface of the vacuum machine body, and an aluminum foil bag is movably disposed between the upper sealing rod and the lower sealing rod.

[0008] A push plate, on the surface of which a nozzle is fixed, and on the inner surface of which a motor is fixed, with screws of opposite helices at both output ends of the motor, and a bracket movably fitted on the outer surface of the screws.

[0009] Preferably, the vacuum machine body has a control panel on its surface, the vacuum machine body and the push plate are connected by a cylinder, and the push plate is located between the upper sealing rod and the lower sealing rod.

[0010] Preferably, the aluminum foil bag has an opening at its port, the nozzle and the bracket correspond to the opening, and there are two sets of brackets symmetrically distributed, with the two sets of brackets located on both sides of the inner wall of the opening.

[0011] Preferably, a drive plate and a movable plate are movably sleeved on the outer surface of the screw. The drive plate has a threaded hole on its surface, and the screw corresponds to and is engaged with the threaded hole. The movable plate has a through hole on its surface, which corresponds to the screw. A transmission spring is provided between multiple sets of movable plates and between the movable plate and the drive plate. The two ends of the transmission spring are respectively fixed to the surface of the movable plate or the drive plate.

[0012] Preferably, a baffle and a bracket are fixed on the side surface of the drive plate. The baffle is provided in two sets, which are symmetrically distributed, and the bracket is located between the two sets of baffles.

[0013] Preferably, a storage rod is fixed to the inner surface of the push plate, a telescopic rod is movably engaged inside the storage rod, a flexible pressure plate is fixed to the end of the telescopic rod, and a spring is movably sleeved on the outer surface of the telescopic rod and the storage rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The conveyor belt transports the aluminum foil bag from its port to the upper end of the lower sealing bar. It stops moving when it reaches the distance sensor position. Then, the control panel, via a drive cylinder, moves the push plate towards the bag opening, inserting the nozzle and two sets of supports into the bag opening. At this point, the motor starts, driving the two sets of screws with opposite rotations. The screw rotation moves the drive plate on the push plate, which in turn moves the movable plate on the outer side of the push plate. A spring then pushes the flexible pressure plate towards the bag opening until the two sets of supports move to both sides of the bag opening, smoothing out any wrinkles. Only then can the motor be turned off. Therefore, besides the two sets of supports and the spray nozzle... The bag opening at the nozzle position and the rest of the bag openings are sealed by two sets of flexible pressure plates. Then, the main body of the vacuum machine drives the upper sealing rod to press down, making the two sets of sealing rods almost closed. At this time, the aluminum foil bag can be vacuumed through the nozzle. When the vacuuming parameters set on the control panel are reached, the vacuuming stops, and the upper and lower sealing rods are completely closed. The aluminum foil bag is then heat-sealed by the heating components on the sealing rods, thus realizing the automation of the nozzle-type vacuum sealing machine. This mechanism does not require much human intervention. The left and right supports can prevent the bag opening from wrinkling, saving labor costs and improving work efficiency.

[0025] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figures 1 to 8 This utility model provides a technical solution: an automatic vacuum conveying device, wherein a vacuum machine body 4 is fixed to the side surface of the conveyor belt 1, and a lower sealing rod 6 is fixed to the surface of the vacuum machine body 4. The lower sealing rod 6 is parallel and attached to the upper surface of the conveyor belt 1. An upper sealing rod 5 is movably disposed on the surface of the vacuum machine body 4. An aluminum foil bag 2 is movably disposed between the upper sealing rod 5 and the lower sealing rod 6. When the contents of the aluminum foil bag 2 reach the vacuum parameters set by the control panel 3, the vacuuming stops. At this time, the upper and lower sealing rods are completely closed, and the aluminum foil bag 2 is heat-sealed by the heating components on the sealing rods. After the heat sealing is completed, the upper and lower sealing rods are lifted, and the conveyor belt 1 transports the vacuum-sealed bag to the next process and receives the next bag that needs to be vacuumed, thereby realizing the automation of the nozzle-type vacuum sealing machine.

[0027] A nozzle 12 is fixed on the surface of the push plate 7, and a motor 11 is fixed on the inner surface of the push plate 7. The output ends of the motor 11 are provided with screws 10 with opposite spirals. A bracket 19 is movably sleeved on the outer surface of the screw 10. Due to the threaded engagement, the rotation of the screw 10 will drive the drive plate 14 to move on the push plate 7. The left and right brackets 19 move to both sides of the bag opening 8 to smooth out the wrinkles of the bag opening 8.

[0028] Based on Embodiment 1, in order to automate the nozzle-type vacuum sealing machine, the surface of the vacuum machine body 4 is provided with a control panel 3. The vacuum machine body 4 and the push plate 7 are connected by a cylinder, and the push plate 7 is located between the upper sealing rod 5 and the lower sealing rod 6.

[0029] The aluminum foil bag 2 has an opening 8 at its port. The nozzle 12 and the bracket 19 are corresponding to the opening 8. There are two sets of brackets 19, which are symmetrically distributed. The two sets of brackets 19 are located on both sides of the inner wall of the opening 8. The left and right sets of brackets 19 move to both sides of the opening 8 to smooth out the wrinkles of the opening 8. The nozzle 12 can perform vacuum treatment on the aluminum foil bag 2.

[0030] A drive plate 14 and a movable plate 20 are movably fitted on the outer surface of the screw 10. The drive plate 14 has a threaded hole 17 on its surface, and the screw 10 corresponds to and is engaged with the threaded hole 17. The movable plate 20 has a through hole on its surface, which corresponds to the screw 10. A transmission spring 21 is provided between multiple sets of movable plates 20 and between the movable plate 20 and the drive plate 14. The two ends of the transmission spring 21 are fixed to the surface of the movable plate 20 or the drive plate 14, respectively. When the screw 10 rotates, it will drive the drive plate 14 to move on the push plate 7. The movement of the drive plate 14 will push the movable plate 20 on the outside of the push plate 7 to move through the transmission spring 21. Without the support of the baffle 18 fixed on the drive plate 14 and the movable plate 20, due to the elasticity of the spring 13, the spring 13 will push the flexible pressure plate 9 to move towards the bag opening 8.

[0031] A baffle 18 and a bracket 19 are fixed on the side surface of the drive plate 14. There are two sets of baffles 18, which are symmetrically distributed. The bracket 19 is located between the two sets of baffles 18. The upper and lower sets of baffles 18 block the flexible pressure plates 9 at the upper and lower ends to prevent the bracket 19 from being interfered with when it is inserted into the bag opening 8.

[0032] A storage rod 16 is fixed to the inner surface of the push plate 7. A telescopic rod 15 is movably locked inside the storage rod 16. A flexible pressure plate 9 is fixed to the end of the telescopic rod 15. A spring 13 is movably sleeved on the outer surface of the telescopic rod 15 and the storage rod 16. Due to the elasticity of the spring 13, the spring 13 will push the flexible pressure plate 9 to move towards the bag opening 8. Therefore, except for the bag openings 8 where the left and right sets of brackets 19 and the nozzle 12 are located, the other bag openings 8 will be covered by the upper and lower sets of flexible pressure plates 9, preventing too much outside air from entering the aluminum foil bag 2 when the nozzle 12 is vacuuming, thus accelerating the vacuuming speed.

[0033] Specifically, the solution is as follows: a distance sensor is installed at nozzle 12, and distance sensors are also installed on the left and right sets of brackets 19. A controller electrically connected to the distance sensors is located inside the vacuum machine body 4. When vacuum sealing the aluminum foil bag 2, the conveyor belt 1 transports the port of the aluminum foil bag 2 to the upper end of the lower sealing rod 6. When it reaches the position of the distance sensor, it stops moving. Because the aluminum foil bag 2 has an elastic strip inside, it opens its bag opening 8. Then, the control panel 3 drives the push plate 7 to move towards the bag opening 8 via a drive cylinder, causing the nozzle 12 to engage with the two sets of brackets 19. When the bag is inserted into the opening 8, the motor 11 starts and drives the two sets of screws 10 with opposite spirals to rotate. Due to the threaded engagement, the rotation of the screws 10 will drive the drive plate 14 to move on the push plate 7. The movement of the drive plate 14 will push the movable plate 20 on the outside of the push plate 7 to move through the transmission spring 21. Without the support of the fixed baffle 18 on the drive plate 14 and the movable plate 20, due to the elasticity of the spring 13, the spring 13 will push the flexible pressure plate 9 to move towards the opening 8 until the two sets of supports 19 move to both sides of the opening 8, smoothing out the wrinkles of the opening 8. The motor can be turned off. Therefore, except for the bag openings 8 where the left and right sets of brackets 19 and nozzle 12 are located, the other bag openings 8 will be sealed by the upper and lower sets of flexible pressure plates 9 to prevent excessive outside air from entering the aluminum foil bag 2 when the nozzle 12 is vacuuming. The presence of the transmission spring 21 allows multiple sets of movable plates 20 to move along with the drive plate 14 on the same side, and the distance between the transmission spring 21 and the two remains the same. Then, the vacuum machine body 4 drives the upper sealing rod 5 to press down so that the two sets of sealing rods are almost closed. At this time, the aluminum foil bag 2 can be vacuumed through the nozzle 12. When the vacuuming parameters set by the control panel 3 are reached, the vacuuming stops. At this time, the upper and lower sets of sealing rods are completely closed, and the aluminum foil bag 2 is heat-sealed by the heating components on the sealing rods. After the heat sealing is completed, the upper and lower sealing rods are lifted, and the conveyor belt 1 transports the vacuumed bag to the next process and picks up the next bag that needs to be vacuumed. This realizes the automation of the nozzle-type vacuum sealing machine. This mechanism does not require much human intervention. The left and right brackets can prevent the bag opening from wrinkling, save labor costs, and improve work efficiency.

[0034] 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.
