Description

Technical Field

[0001] This utility model belongs to the field of air filling machines, specifically, it relates to an air filling machine with a protective structure. Background Technology

[0002] A filling machine is used to fill a certain quantity of pressurized gas into an aerosol can. Since aerosol products require a certain pressure, the filling machine fills the gas through a valve at the top of the aerosol can.

[0003] Chinese patent CN215489068U discloses a cryogenic gas filling safety protection device. In use, by pulling two L-shaped side plates out from within a rectangular plate, the distance between the two L-shaped side plates can be adjusted. Four bolts are then passed through the four mounting holes and screwed into the conveyor to complete the fixed installation of the device. Next, by pulling the support arm, the shaft and two positioning rods are pulled out from within the support column. The height of the hydraulic cylinder with the filling head is adjusted according to the height of the container to complete the device's debugging. Then, the gas delivery pipe is connected to the filling head, and the container is moved below the filling head via the conveyor. The hydraulic cylinder pushes the filling head to connect to the container's air inlet. Finally, two cylinders push two clamping claws from both sides to clamp and fix the container, preventing it from shaking or tipping over.

[0004] However, the aforementioned cryogenic gas filling safety protection device uses two cylinders to drive an arc-shaped plate-shaped gripper to position the aerosol can. The aerosol can is prone to shaking when it is being filled, which can cause the ends of the arc-shaped plate-shaped gripper to deform and shake, resulting in low stability in positioning the aerosol can.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an air filling machine with a protective structure.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] An air-filling machine with a protective structure includes a U-shaped base, two protective mechanisms respectively disposed on opposite sides of the U-shaped base, and an air-filling mechanism disposed on the upper side of the U-shaped base. The protective mechanism includes a sliding plate slidably fitted in the U-shaped base, a first electric push rod for driving the sliding plate to slide, a clamping bar slidably fitted on one side of the sliding plate, two clamping plates elastically slidably fitted on one side of the clamping bar, and a transmission bar hinged between the clamping plates and the sliding plate. In one protective mechanism, the clamping plate has a T-shaped strip structure, and in the other protective mechanism, the clamping plate is provided with a T-shaped slot.

[0009] Optionally, a cross-shaped slide is provided on one side of the clamping strip, and a cross-shaped protrusion is provided at one end of the clamping plate, with the cross-shaped protrusion slidingly fitted within the cross-shaped slide.

[0010] Optionally, a spring damper is provided between the inner wall of the cross-shaped slide and the cross-shaped protrusion.

[0011] Optionally, a groove is provided on one side of the cross-shaped protrusion, and the spring damper is located in the groove.

[0012] Optionally, two guide rods are provided on one side of the clamping strip, and a first guide hole corresponding to the guide rods is provided on one side of the sliding plate, with one end of the guide rod slidingly engaged in the first guide hole.

[0013] Optionally, a second guide hole corresponding to the guide rod is provided on one side of the U-shaped seat, and one end of the guide rod is slidably fitted in the second guide hole.

[0014] Optionally, the distance between two adjacent transmission bars gradually decreases from the end closer to the sliding plate to the end closer to the clamping bar.

[0015] Optionally, the filling mechanism includes a support plate on the upper side of the U-shaped seat, a second electric push rod on the support plate, and a filling head that passes through one end of the support plate via the output shaft of the second electric push rod.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] By placing the aerosol can between two protective mechanisms, the first electric push rod is activated to drive the sliding plate to slide the clamping strips. The clamping plate of one protective mechanism is inserted into the T-shaped slot of the other protective mechanism, so that the clamping plates of the two protective mechanisms are aligned. After the two clamping strips come into contact with the aerosol can, the sliding plate continues to slide, and the two clamping plates on the side of the clamping strips slide towards each other through the transmission bar. In turn, the clamping plates hold the aerosol can, and the clamping strips and clamping plates form a U-shaped frame structure to protect the aerosol can, position the side of the aerosol can, and reduce the probability of the aerosol can shaking when it is being filled.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-3 As shown, this embodiment provides an air filling machine with a protective structure, including a U-shaped base 1, two protective mechanisms 2 respectively disposed on opposite sides of the U-shaped base 1, and an air filling mechanism 3 disposed on the upper side of the U-shaped base 1. The protective mechanism 2 includes a sliding plate 200 slidably fitted in the U-shaped base 1, a first electric push rod 201 for driving the sliding plate 200 to slide, a clamping bar 202 slidably fitted on one side of the sliding plate 200, two clamping plates 203 elastically slidably fitted on one side of the clamping bar 202, and a transmission bar 204 hinged between the clamping plates 203 and the sliding plate 200. In one protective mechanism 2, the clamping plate 203 has a T-shaped strip structure, and in the other protective mechanism 2, the clamping plate 203 is provided with a T-shaped slot 205.

[0028] By placing the aerosol can between the two protective mechanisms 2, the first electric push rod 201 is activated to drive the sliding plate 200 to slide the clamping strip 202. The clamping plate 203 of one protective mechanism 2 is inserted into the T-shaped slot 205 of the other protective mechanism 2, so that the clamping plates 203 of the two protective mechanisms 2 are connected. After the two clamping strips 202 come into contact with the aerosol can, the sliding plate 200 continues to slide. The transmission bar 204 drives the two clamping plates 203 on the side of the clamping strip 202 to slide towards each other, thereby clamping the aerosol can through the clamping plates 203. The clamping strips 202 and clamping plates 203 form a U-shaped frame structure to protect the aerosol can, position the side of the aerosol can, and reduce the probability of the aerosol can shaking when it is being filled.

[0029] Please see Figure 2-3 As shown, in this embodiment, the clamping bar 202 is provided with a cross-shaped slide 206 on one side, and the clamping plate 203 is provided with a cross-shaped protrusion 207 at one end. The cross-shaped protrusion 207 is slidably fitted in the cross-shaped slide 206, which facilitates the sliding of the cross-shaped protrusion 207 through the cross-shaped slide 206 and improves the sliding stability of the clamping plate 203.

[0030] Please see Figure 2 As shown, a spring damper 208 is provided between the inner wall of the cross-shaped slide 206 and the cross-shaped protrusion 207 in this embodiment. This allows the spring damper 208 to maintain the initial position of the clamping plate 203 before the clamping bar 202 is blocked by the aerosol can. This facilitates the insertion of the clamping plate 203 of one protection mechanism 2 into the T-shaped slot 205 of another protection mechanism 2. A groove 209 is provided on one side of the cross-shaped protrusion 207, and the spring damper 208 is located in the groove 209, which helps to reduce the influence of the spring damper 208 on the sliding range of the cross-shaped protrusion 207.

[0031] Please see Figure 2-3 As shown, in this embodiment, the clamping bar 202 is provided with two guide rods 210 on one side, and the sliding plate 200 is provided with a first guide hole 211 corresponding to the guide rods 210 on one side. One end of the guide rod 210 is slidably fitted in the first guide hole 211. The U-shaped seat 1 is provided with a second guide hole 4 corresponding to the guide rod 210 on one side. One end of the guide rod 210 is slidably fitted in the second guide hole 4, which facilitates the stability of the sliding plate 200 and the clamping bar 202 sliding through the guide rods 210.

[0032] Please see Figure 2 As shown, in this embodiment, the distance between two adjacent transmission bars 204 gradually decreases from the end near the sliding plate 200 to the end near the clamping bar 202, so that after the two clamping bars 202 come into contact with the aerosol can, the sliding plate 200 continues to slide, and the transmission bars 204 drive the two clamping plates 203 on the side of the clamping bar 202 to slide towards each other.

[0033] Please see Figure 2-3 As shown, the filling mechanism 3 of this embodiment includes a support plate 301 on the upper side of the U-shaped seat 1, a second electric push rod 302 on the support plate 301, and a filling head 303 with the output shaft of the second electric push rod 302 passing through one end of the support plate 301, so as to facilitate the filling head 303 to squeeze the valve on the aerosol can and fill the aerosol can with air by driving the second electric push rod 302.

[0034] Working principle: The aerosol can is placed between the two protective mechanisms 2. The first electric push rod 201 is turned on to drive the sliding plate 200 to slide the clamping strip 202. The clamping plate 203 of one protective mechanism 2 is inserted into the T-shaped slot 205 of the other protective mechanism 2, so that the clamping plates 203 of the two protective mechanisms 2 are connected. After the two clamping strips 202 come into contact with the aerosol can, the sliding plate 200 continues to slide. Through the transmission bar 204, the two clamping plates 203 on the side of the clamping strip 202 slide towards each other, thereby clamping the aerosol can through the clamping plates 203. The clamping strips 202 and clamping plates 203 form a U-shaped frame structure to protect the aerosol can, position the side of the aerosol can, and reduce the probability of the aerosol can shaking when it is being filled.
