Description

Technical Field

[0001] This utility model relates to the technical field of abrasive packaging equipment, specifically an abrasive packaging equipment for shot blasting cleaning. Background Technology

[0002] Metal abrasives are a key consumable in the shot blasting and surface cleaning industry, and their usage is enormous. In the entire production and recycling process, the packaging of finished abrasives is an essential final step, directly affecting the storage, transportation, and subsequent use of the materials. Currently, there are two packaging methods for abrasives: manual packaging and semi-automatic mechanical packaging. Manual packaging relies entirely on workers manually wrapping the abrasive with stretch film, resulting in extremely high labor intensity, low production efficiency, extended production cycles, and high labor costs. Semi-automatic mechanical packaging uses a rotating platform with a liftable film frame to replace manual wrapping, improving packaging efficiency to some extent. However, on the one hand, the power cords and other external cables driving the rotating platform are prone to tangling during the rotation and packaging process, affecting the continuous packaging operation; on the other hand, fixing the beginning and cutting the end of the stretch film before packaging usually still requires manual operation, limiting further efficiency improvements.

[0018] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides an abrasive packaging device for shot blasting, used to package and cover the abrasive packaging boxes 5 with film. After being bagged, the abrasives used for shot blasting are usually packed into packaging boxes 5 for easy transport by vehicle. Currently, the packaging boxes 5 are placed on forklift pallets during packaging for easy handling by forklift.

[0019] The abrasive packaging equipment provided in this application is integrated into an existing production line to form a transportation-packaging integrated system, improving abrasive production efficiency and convenience. The abrasive packaging equipment includes a rotary packaging device 1 and a film supply device 2. The rotary packaging device 1 is located on the conveying path of the roller conveyor line 4 and is connected to the roller conveyor line 4. It receives the abrasive packaging boxes 5 conveyed by the roller conveyor line 4 and drives the packaging boxes 5 to rotate. Of course, there can be two roller conveyor lines 4, located upstream and downstream of the rotary packaging device 1 respectively, allowing the packaging boxes 5 to flow into and out of the packaging station without obstruction, achieving continuity of the production process.

[0020] To connect with the roller conveyor line 4, the rotary packaging device 1 includes a disc-shaped rotating platform 11. A support platform 12 for supporting the packaging boxes 5 is mounted on the rotating platform 11, and the support platform 12 rotates synchronously with the rotating platform 11. The support platform 12 includes a roller frame 121 mounted on the rotating platform 11. Multiple rotating rollers 122 are rotatably connected to the top of the roller frame 121. The rotating shafts of the rotating rollers 122 extend horizontally, and the multiple rotating rollers 122 are evenly spaced and arranged side-by-side along the conveying direction of the roller conveyor line 4. The top surface of the support platform 12 is at the same height as the top surface of the roller conveyor line 4.

[0021] The rotating platform 11 is mounted on the base of the packing equipment via bearings, allowing it to rotate freely about a vertical axis. This base is placed on the ground to provide stable support for the packing equipment. The power source driving the rotation of the rotating platform 11 is a first drive unit 13.

[0022] The rotating platform 11 is also equipped with a second driver 14 for driving at least one rotating roller 122 to rotate. The function of the second driver 14 is to drive the rotating roller 122 to rotate when the packaging box 5 needs to enter or exit the carrying platform 12, thereby using friction to accurately pull the packaging box 5 into or out of the work station, realizing automatic positioning and unloading, and playing an indispensable role in the continuous transportation and movement of the packaging box 5.

[0023] In this embodiment, the first driver 13 and the second driver 14 are specifically selected as passive rechargeable drive motors. These motors integrate high-energy-density energy storage units, such as supercapacitor banks or lithium batteries, which can be quickly replenished during equipment downtime via contact charging stations or wireless charging. This design eliminates the need for external power cables to be dragged along the drives on the rotating platform 11, fundamentally solving the risk of cable and signal line entanglement, breakage, and wear caused by long-term, frequent rotation, and greatly improving the operational reliability, safety, and layout flexibility of the equipment.

[0024] In this embodiment, the second driver 14 is located below the plurality of rotating rollers 122. Its driving end is connected to one end of the two middle rotating rollers 122 via a sprocket-chain transmission, and drives these two rotating rollers 122 to rotate. Among the plurality of rotating rollers 122, adjacent rotating rollers 122 are also transmitted to each other via a sprocket-chain transmission. In this embodiment, the transmission ends of the plurality of rotating rollers 122 are all located on the same side.

[0025] To ensure that the packaging box 5 does not slip off the side of the rotating roller 122 during rotation or conveying, a limiting retaining ring 123 is provided on the roller surface near both ends of each rotating roller 122. This pair of retaining rings forms a guide groove with a width greater than the width of the forklift pallet, which effectively limits the lateral movement of the packaging box 5 and the forklift pallet below it.

[0026] The film supply device 2 is located outside the rotation range of the rotary packing device 1 and is used to supply stretch film 6. The stretch film 6 here is a film commonly used in logistics, packaging, and other fields, possessing certain stretch self-adhesive properties; it is also known as stretch film. The film supply device 2 includes a film holder 21 and a film holder lifting mechanism 22. The film holder 21 is used to mount a large-diameter roll of stretch film 6, with the film roll's axis vertical so that the stretch film 6 can be output laterally outwards, and the width of the stretch film 6 extends vertically to wrap around the upright side of the packaging box 5. The film holder lifting mechanism 22 is used to move the film holder 21 up and down, so that the stretch film 6, pulled horizontally from the film roll, can evenly wrap around the entire side surface of the rotating packaging box 5 in a spiral trajectory.

[0027] It should be noted that the design focus of this application is not on the membrane supply device 2. Therefore, the mold frame and mold frame lifting mechanism of the membrane supply device 2 can adopt the same structure that is currently available on the market. This application does not limit or redundantly describe them here.

[0028] In addition, this embodiment also includes a control unit (not shown in the figure) and a position sensor (not shown in the figure). The control unit can be a PLC. The position sensor is a photoelectric sensor, with its transmitter and receiver installed on both sides of the corresponding upstream roller conveyor line 4 end position, for accurately detecting whether the packaging box 5 has reached the predetermined trigger position. The control unit can be installed in a separate electrical control cabinet, and can be wirelessly connected to the first driver 13 and the second driver 14, and wirelessly or wiredly connected to the position sensor and the film carriage lifting mechanism 22, respectively, to receive signals and issue control commands.

[0029] The abrasive packaging equipment of this embodiment includes the following steps during use: S11. The packaging box 5 containing abrasive material moves along the upstream roller conveyor line 4. When the packaging box 5 triggers the position sensor, the position sensor sends a signal to the control unit. The control unit then activates the second drive 14, driving the active rotating roller 122 on the support platform 12 to rotate forward, smoothly and accurately pulling the packaging box 5 into the predetermined center position of the support platform 12. After it is in place, the second drive 14 stops.

[0030] S12. The operator manually pulls out the free end of the film 6 wrapped on the film holder 21 and fixes it to the packaging box 5 or the forklift pallet below it by adhesive or binding. Then, the operator sends a start command to the control unit through the human-machine interface or button.

[0031] S13. Upon receiving the instruction, the control unit synchronously starts the first driver 13 and the film frame lifting mechanism 22. The first driver 13 drives the rotating platform 11, causing the supporting platform 12 and the packaging box 5 on it to rotate at a uniform speed. At the same time, the film frame lifting mechanism 22 drives the film frame 21 to move up and down according to a preset mode. During this process, the wrapping film 6 is continuously pulled out and wraps the packaging box 5 in a spiral manner. The number of wrapping turns and layers is controlled by the control unit based on feedback from the rotary encoder or time.

[0032] S14. Once the winding reaches the preset requirements, the control unit automatically stops the first drive 13 and the film carriage lifting mechanism 22. At this time, the operator needs to manually cut the winding film 6 connecting the packaging box 5 and the film roll. Then, the control unit starts the second drive 14 to send the packaged packaging box 5 out of the carrying platform 12 and into the downstream roller conveyor line 4 for transport. The operator manually fixes the film end to the next packaging box 5 again to start a new cycle.

[0033] Although the abrasive packaging equipment provided in this embodiment still requires manual initial fixing and final cutting of the membrane, the problem of cable entanglement in the rotating part has been solved by a passive rechargeable motor, making the operation safer and more reliable.

[0034] Example 2 In addition to including all the components of Embodiment 1, such as the rotary packaging device 1, the film supply device 2, the control unit, and the position sensor, the device structure of this embodiment also includes a follow-up clamping and cutting device 3, such as... Figures 3 to 5 As shown.

[0035] The follow-up clamping and cutting device 3 is installed on the upper surface of the rotating platform 11. Specifically, when not in the packaging operation, i.e., when the rotating packaging device 1 is not rotating, it is located between the roller frame 121 of the carrying platform 12 and the film supply device 2, and is used to clamp and cut the wrapping film 6. Furthermore, the position of the follow-up clamping and cutting device 3 is exactly opposite to one end of the rotating roller 122 driven by the second driver 14, and is located on both sides of the roller frame 121 to avoid working interference between the two.

[0036] The follow-up clamping and cutting device 3 rotates synchronously with the rotating platform 11, and includes a clamping and cutting mechanism 31 and a clamping and lifting mechanism 32.

[0037] The clamping and lifting mechanism 32 is used to drive the entire clamping and cutting mechanism 31 to perform vertical lifting motion. Considering the space limitations on the rotating platform 11 and the requirements for motion accuracy, this embodiment preferably uses a lead screw lifting module driven by a micro servo motor as the clamping and lifting mechanism 32. Specifically, the clamping and lifting mechanism 32 includes a fixed frame fixed on the rotating platform 11, a lead screw rotatably connected to the fixed frame, driven by a micro servo motor, rotating around its own vertical axis, and a slider threadedly connected to the lead screw, with the slider slidingly engaged with the fixed frame.

[0038] The clamping and cutting mechanism 31 includes a mounting base 311. A slider, serving as the output end of the clamping and lifting mechanism 32, is connected to the mounting base 311, driving the clamping and cutting mechanism 31 to move vertically. A pair of clamping plates are provided on the mounting base 311, horizontally opposite to each other and capable of opening and closing relative to each other. Specifically, the pair of clamping plates are a fixed plate 312 and a movable plate 313. The fixed plate 312 is fixedly connected to the mounting base 311. The movable plate 313 is slidably connected to the mounting base 311 and driven by a clamping and cutting drive cylinder. In this embodiment, the clamping and cutting drive cylinder is a small, high-performance linear electric push rod. Its cylinder body is fixed to the mounting base 311, and its push rod end is connected to the movable plate 313, allowing precise control of the movable plate 313 to move horizontally closer to or further away from the fixed plate 312, thus realizing the opening and closing action of the clamping plates. In this embodiment, the clamping and cutting drive cylinder is positioned closer to the interior of the rotating platform 11 than the movable plate 313, so that when the movable plate 313 performs a closing action, it moves from outside the rotating platform 11 to inside the rotating platform 11. Figure 3 As shown, this is to make reasonable use of the space above the rotating platform 11 and to avoid collisions with other facilities or interference with the wrapping action of the stretch film 6 during packaging.

[0039] The fixed plate 312 and the movable plate 313 are two parallel vertical strips, the length of which is greater than the width of the stretch film 6. Figure 4 and Figure 5 As shown, clamping blocks 314 are provided on the opposing surfaces of the fixed plate 312 and the movable plate 313 to clamp the stretch film 6. The two clamping blocks 314 extend along the length of the clamping plates and their length is greater than the width of the stretch film 6.

[0040] In addition, a cutting blade 315 is provided on the clamping plate to cut the wrapping film 6. The cutting blade 315 is located on the side of the clamping plate closer to the support platform 12, specifically closer to the support platform 12 than the clamping block 314, that is, the clamping block 314 is located on the side of the cutting blade 315 away from the support platform 12.

[0041] In one embodiment, each of the two clamping plates is provided with a cutting blade 315, with the blades of the two cutting blades 315 facing each other, and the two working together to cut the stretch film 6. However, this design has high requirements for the material and precision of the cutting blades 315, and is not a preferred design.

[0042] In a preferred embodiment, a cutting blade 315 is provided on only one of the pair of clamps, while a blade pad 316 is provided on the other clamp corresponding to the position of the cutting blade 315 to cooperate with the cutting blade 315. The blade pad 316 is made of a hard and slightly tough material, such as high-density polyethylene or special hardwood, which can both cooperate with the cutting blade 315 to cleanly and neatly cut the wrapping film 6, and avoid damage to the blade edge by hard impact.

[0043] In this embodiment, more preferably, the cutting blade 315 is disposed on the fixed plate 312 and the blade pad 316 is disposed on the movable plate 313, so as to prevent the movable plate 313 from being cut first when it pulls the stretch film 6 closer to the fixed plate 312.

[0044] The two clamping blocks 314 are preferably made of a material with high elasticity and a high coefficient of friction, such as polyurethane elastomer, and their clamping surfaces are processed with mesh or striped anti-slip textures. Meanwhile, the height of the cutting blade 315 protruding from the surface of the fixed plate 312 is slightly less than the protrusion height of the clamping block 314 on the fixed plate 312. Similarly, the protrusion height of the blade pad 316 is slightly less than the protrusion height of the clamping block 314 on the movable plate 313. Therefore, when the movable plate 313 and the fixed plate 312 are closed, the two clamping blocks 314 first clamp and fix the stretch film 6. Then, through a slight deformation of the two clamping blocks 314, the blade of the cutting blade 315 contacts the blade pad 316 and cooperates to cut the stretch film 6. This design avoids the cutting blade 315 cutting the stretch film 6 before the two clamping blocks 314 have clamped it tightly, ensuring that the cutting blade 315 cuts the stretch film 6 no earlier than the moment the pair of clamping plates hold the stretch film 6.

[0045] In addition to being connected to the components in the embodiment, the control unit is also connected to the micro servo motor and the clamping drive cylinder of the clamping and lifting mechanism 32 in this embodiment, so as to coordinate and control all the actions of the follow-up clamping and cutting device 3.

[0046] The abrasive packaging equipment of this embodiment includes the following steps during use: S21. This step is the same as step S11 in Example 1, and will not be repeated here.

[0047] S22. For the first packaging box 5, the operator only needs to initially extend the film end and place it in front of the clamping jaws of the clamping and cutting mechanism 31. The control unit first controls the clamping and cutting lifting mechanism 32 to raise the clamping and cutting mechanism 31 to a high position, and then controls the clamping and cutting drive cylinder to close the movable plate 313, using two clamping blocks 314 to clamp the free end of the wrapping film 6.

[0048] S23. Control the rotating platform 11 to rotate. When the rotating platform 11 drives the packaging box 5 to rotate nearly one revolution, the control unit instructs the clamping and lifting mechanism 32 to operate, lowering the clamping and cutting mechanism 31 to a low position. This lowering and avoidance action lowers the clamping and cutting mechanism 31 entirely below the wrapping layer of the wrapping film 6 to be formed, thereby preventing itself from being wrapped by the wrapping film 6 during subsequent wrapping. The clamping and cutting mechanism 31 remains clamped in the low position, and the film end it clamps becomes the starting fixed point for wrapping the packaging box 5. For the subsequent wrapping process, refer to step S13 of Embodiment 1.

[0049] S24. When the winding reaches the preset requirements, the control unit automatically stops the first driver 13 and the film frame lifting mechanism 22.

[0050] S25, control the movable plate 313 to open, and then control the clamping and lifting mechanism 32 to raise the clamping and cutting mechanism 31 from the low position to the high position again. At this time, the fixed plate 312 and the movable plate 313 are located on both sides of the winding film 6 between the carrying platform 12 and the film supply device 2, respectively.

[0051] S26. Control the clamping and cutting drive cylinder to drive the movable plate 313 to close quickly. During the closing process, firstly, the two elastic clamping blocks 314 contact and press the suspended "film bridge" located between the packaging box 5 and the film roll. Due to the material elasticity of the clamping blocks 314, deformation occurs, thereby providing a huge static friction force to reliably clamp the film. Subsequently, as the closing action continues, the cutting edge of the cutting blade 315 presses into the opposite blade pad 316, completely cutting the film behind the clamping point, ensuring that the film is firmly gripped during cutting and will not retract or loosen.

[0052] At this point, the packaging operation of the current packaging box 5 is completed, the stretch film 6 is cut, and simultaneously, the newly formed free end of the stretch film 6 is tightly clamped between the two clamping blocks 314 and remains in a high position with the clamping and cutting mechanism 31. This automatically prepares the starting end for the next packaging box 5 to be wrapped.

[0053] S27. The control unit starts the second drive 14 to deliver the packaged box 5. After the next packaged box 5 arrives, the fully automatic cycle can start directly from step S23.

[0054] In step S25, after the movable plate 313 opens, a small section of film extends beyond the packaging box 5, previously clamped at the end. This portion of film risks entanglement with the rotating roller 122 during subsequent transportation, affecting the normal transport of the packaging box 5. However, in practical use, this problem can be mitigated by installing the follow-up clamping and cutting device 3 as close as possible to the parking position of the packaging box 5 to shorten the length of this useless film and reduce the associated risk. Alternatively, it can be handled manually, such as by adhering it to the side of the packaging box or cutting it off. Although this introduces a small amount of manual operation, the equipment in this embodiment still significantly saves manpower compared to existing mechanical packaging methods.

[0055] The abrasive packaging equipment provided in this embodiment integrates a follow-up clamping and cutting device 3 on the rotating platform 11 and successfully improves the automation of the equipment in Embodiment 1 through the action of "high-level clamping - lowering to avoid - rising to clamp and cut", which greatly improves the efficiency of packaging operations and reduces labor costs and labor intensity.
