Description

Technical Field

[0001] The utility model belongs to the technical field of material packaging equipment, and particularly relates to a lifting material packaging platform. Background Art

[0002] In today's industrial production environment, packaging is a crucial component of the logistics chain. Loading materials in the packaging room often faces a series of challenges, including low efficiency, high labor intensity, high safety risks, and reliance on worker skills. Traditional loading methods often require workers to carry materials to the packaging equipment. This operation mode not only consumes a lot of manpower but also may lead to occupational diseases due to long-term repetitive work.

[0003] With the upgrading of the industry, for small-sized flaky granular materials such as polyester chips, the operation mode of manual handling and packaging is no longer used. Instead, pneumatic conveying technology is used to transport the polyester chips to the storage tank in the packaging room. The bottom of the storage tank is connected to a discharge pipe. The transport vehicle moves to the bottom of the discharge pipe and connects the feed port of the packing bag on the transport vehicle with the discharge port of the discharge pipe. In this way, the material in the storage tank can enter the packing bag under the action of gravity, thus completing the material packaging work and reducing the workload of the workers. However, in this operation mode, workers need to climb onto the transport vehicle and manually put the packing bag on the discharge pipe. After the material is packaged, the workers climb down from the transport vehicle; the whole process is dangerous for workers to climb up and down. Moreover, due to the lack of a connecting structure between the packing bag and the discharge pipe, the workers need to manually connect the packing bag and the discharge pipe throughout the packaging process. As a result, the material in the packing bag gradually increases, squeezing the transportation space of the transport vehicle. The risk factor of workers standing in the transportation space increases, posing a major safety hazard. Utility Model Content

[0004] The utility model is intended to provide a lifting material packaging platform to solve the problem of high risk caused by the need for workers to climb onto a transport vehicle and connect packaging bags and a discharge pipe on the transport vehicle during the existing polyester chip packaging process.

[0005] In order to achieve the above-mentioned purpose, the solution of the utility model is: a lifting material packaging platform, including a loft deck, a lifting platform, a telescopic discharge pipe, a first drive component for driving the lifting platform to rise and fall, and a second drive component for driving the telescopic discharge pipe to extend and retract. The loft deck is horizontally fixedly installed in the packaging room, and the loft deck divides the space of the packaging room into an upper space and a lower space. A passage for connecting the upper space and the lower space is provided on the loft deck, and a mounting frame for installing the second drive component is provided on the loft deck, and the mounting frame is located above the passage; the first drive assembly is fixedly installed on the loft deck, and the lifting platform is located below the passage. A ladder for people to enter and exit the lifting platform is fixedly installed on the loft deck, and a through hole opposite to the telescopic discharge pipe is provided on the lifting platform.

[0006] The working principle and beneficial effects of this solution are as follows: in this solution, the lifting platform is driven by the first drive assembly to raise and lower the lifting platform so that the distance between the lifting platform and the transport vehicle can be adjusted; secondly, the telescopic discharge pipe is driven by the second drive assembly to extend and retract the discharge pipe so that the distance between the discharge port of the telescopic discharge pipe and the transport vehicle can be adjusted. In this way, workers can ascend the stairs to the loft deck and enter and exit the lifting platform by climbing the ladder. From the lifting platform, they can lift the bag opening of the transport vehicle through the through hole of the lifting platform and attach it to the discharge port of the telescopic discharge pipe, thereby completing the loading and packaging of materials. This avoids workers having to climb onto the transport vehicle to load and pack materials, improving work safety and reducing safety hazards.

[0011] Optionally, the first drive assembly further includes four electric hoists, the four corners of the lifting platform are fixedly connected with lifting rings, and the hooks of the four electric hoists are respectively hung with the four lifting rings.

[0012] In this solution, four electric hoists can drive the lifting platform to rise and fall stably.

[0013] Optionally, the mounting frame includes a frame body and a mounting plate, the frame body is welded to the attic support plate, the mounting plate is arranged at the top of the frame body, a discharge pipe is provided on the mounting plate, the discharge pipe passes through the mounting plate, the telescopic discharge pipe is fixedly connected to the bottom end of the discharge pipe, and the end of the telescopic discharge pipe away from the discharge pipe is fixedly connected to a connecting disk; the second driving assembly includes a retraction rope, a guide wheel, a retraction shaft and a driving motor that rotates in the same manner as the driving retraction shaft, the number of retraction ropes is at least three, a through hole for the retraction rope to pass through is opened on the mounting plate, the guide wheel is fixedly mounted on the mounting plate, the number of guide wheels is the same as the number of retraction ropes, one end of the retraction rope is connected to the connecting disk, and the other end of the retraction rope passes around the corresponding guide wheel and is wound around the retraction shaft.

[0014] In this solution, the driving motor drives the reel to rotate, and the reel rope is wound around the reel or released from the reel, thereby lifting the connecting disk upward or releasing it downward, thereby realizing the extension and retraction of the retractable discharge tube.

[0015] Optionally, at least three winding grooves for the winding rope to be trapped are provided on the outer peripheral wall of the winding shaft.

[0016] In this solution, the retractable rope is wound in the corresponding retracting groove, and the retracting groove can limit the retractable rope to ensure that the retracted and released amount of the retractable rope is the same, thereby ensuring the horizontal lifting and lowering of the connecting disk.

[0017] Optionally, the mounting plate is horizontally slidably connected to the frame, and the top end of the discharge pipe is fixedly connected to a flexible tube.

[0018] In this solution, the mounting plate can slide horizontally on the frame, thereby achieving horizontal movement of the telescopic discharge pipe, so that workers can adjust the horizontal position of the telescopic discharge pipe according to on-site conditions.

[0019] Optionally, an I-shaped rail is fixedly mounted on the top of the frame, and a track pulley that matches the I-shaped rail is fixedly mounted on the bottom surface of the mounting plate.

[0020] In this solution, the sliding connection between the mounting plate and the frame is achieved through the cooperation between the track pulley and the I-rail, and it is convenient for workers to push the mounting plate to slide horizontally.

[0029] Example 1

[0030] This embodiment is basically as Figure 1 and Figure 2 The figure shows a lifting material packaging platform, comprising a mezzanine deck 1, a lifting platform 2, a telescopic discharge pipe 3, a first drive assembly for driving the lifting platform 2 up and down, and a second drive assembly for driving the telescopic discharge pipe 3 to extend and retract. The mezzanine deck 1 is fixedly installed horizontally within the packaging room, dividing the packaging room into an upper space and a lower space. A passage 101 is provided on the mezzanine deck 1 to connect the upper and lower spaces. The lifting platform 2 is located below the passage 101. A ladder 4 is welded to the mezzanine deck 1 for personnel to enter and exit the lifting platform 2.

[0031] The first drive assembly is fixedly mounted on the mezzanine deck 1. In this embodiment, the first drive assembly includes four hydraulic cylinders 5. The output ends of the four hydraulic cylinders 5 are fixedly connected to the four corners of the lifting platform 2. In this way, the lifting platform 2 is raised and lowered by the hydraulic cylinders 5. In addition, the control switches of the hydraulic cylinders 5 (including the up switch and the down switch) are fixedly mounted on the lifting platform 2. Guardrails 6 are fixedly mounted on all four sides of the lifting platform 2, and a through hole 201 is formed in the lifting platform 2.

[0032] A mounting bracket for mounting the second drive assembly is provided on the attic deck 1 and is located above the channel 101. The mounting bracket comprises a frame 7 and a mounting plate 8. The frame 7 is welded to the attic deck 1, and the mounting plate 8 is horizontally slidably connected to the top of the frame 7. Specifically, an I-shaped track 9 is welded to the top of the frame 7, and a track pulley 10 that cooperates with the I-shaped track 9 is fixedly mounted on the bottom surface of the mounting plate 8. In this way, the track pulley 10 rolls on the I-shaped track 9, achieving a horizontal sliding connection between the mounting plate 8 and the frame 7. A discharge pipe 11 is provided on the mounting plate 8, which passes through the mounting plate 8. The top of the discharge pipe 11 is fixedly connected to a flexible tube 12, and the end of the flexible tube 12 away from the discharge pipe 11 is fixedly connected to a discharge pipe 13; the bottom end of the discharge pipe 11 is fixedly connected to the top of the telescopic discharge pipe 3, and the bottom end of the telescopic discharge pipe 3 is fixedly connected to a connecting plate 14, on which at least three connecting rings 15 are welded, and the connecting rings 15 are evenly distributed along the circumference of the connecting plate 14.

[0033] Combine Figure 2 As shown, the second drive assembly includes a retractable rope 16, a guide wheel 17, a reel 18, and a drive motor 19 that drives the reel 18 in rotation. There are at least three retractable ropes 16. The mounting plate 8 is provided with a through hole for the retractable rope 16 to pass through. A support plate 20 is welded to the mounting plate 8, and a U-shaped plate 21 is welded to the support plate 20. The guide wheel 17 is rotatably mounted on the U-shaped plate 21. The number of guide wheels 17 is the same as the number of retractable ropes 16. One end of the retractable rope 16 is tied to the corresponding connecting ring 15. The other end of the retractable rope 16 passes through the through hole of the mounting plate 8, passes around the corresponding guide wheel 17, and is wound around the retractable shaft 18. The outer wall of the retractable shaft 18 is provided with at least three retractable grooves 181 for the retractable rope 16 to enter. In this way, the retractable rope 16 is wound in the corresponding retractable grooves 181. In this embodiment, there are three retractable ropes 16 , three connecting rings 15 , three guide wheels 17 , and three reeling grooves 181 .

[0034] During actual use, the transport vehicle moves to the bottom of the lifting platform 2, and the worker climbs up to the attic deck 1 via the stairs and enters the lifting platform 2 via the ladder 4. Since the control switch of the hydraulic cylinder 5 (the control switch includes an up switch and a down switch) is fixedly installed on the lifting platform 2, the worker on the lifting platform 2 can control the lifting and lowering of the lifting platform 2 through the control switch. In this way, after the worker enters the lifting platform 2, he presses the down switch to control the operation of the hydraulic cylinder 5, and the hydraulic cylinder 5 drives the lifting platform 2 to descend. After the lifting platform 2 descends to the appropriate position, the worker no longer presses the down switch, the hydraulic cylinder 5 stops working, and the lifting platform 2 hovers above the transport vehicle.

[0035] Next, the telescopic discharge tube 3 extends under the drive of the second drive assembly. Specifically, the drive motor 19 rotates the reel shaft 18 clockwise, releasing the reel cord 16 wrapped in the reel slot 181. This allows the reel cord 16 to smoothly lower down the connecting plate 14, allowing the telescopic discharge tube 3 to extend under the action of gravity, and the discharge opening of the telescopic discharge tube 3 to descend. When the discharge opening of the telescopic discharge tube 3 descends to the appropriate position, the drive motor 19 stops. Subsequently, the worker uses a tool (such as a long pole with a hook) to hook the bag opening from the transport vehicle to the lifting platform 2 through the through hole 201 and then fit the bag opening over the discharge opening of the telescopic discharge tube 3. Then, the material enters the packing bag through the discharge pipe 13, the flexible pipe 12, the discharge pipe 11 and the telescopic discharge pipe 3. After loading for a period of time, the loading is stopped, and the workers on the lifting platform 2 manually tie and seal the bag opening of the packing bag, and then put the bag opening of the packing bag back onto the transport vehicle through the through hole 201 to complete the material packaging operation.

[0036] Finally, the worker presses the up switch, and hydraulic cylinder 5 drives lift platform 2 upward. After lift platform 2 resets, the worker stops pressing the up switch, hydraulic cylinder 5 stops, and lift platform 2 comes to a standstill, allowing the worker to exit lift platform 2 via ladder 4. Simultaneously, drive motor 19 activates, driving reel 18 to rotate counterclockwise. Reel cord 16 winds into reel slot 181 of reel 18, pulling connecting plate 14 upward. This shortens telescopic feed tube 25 and raises the discharge port of telescopic discharge tube 3. After the feed port of telescopic feed tube 25 rises and resets, drive motor 19 stops. This positions both lift platform 2 and the discharge port of telescopic discharge tube 3 away from the transport vehicle, allowing the vehicle to depart smoothly.

[0037] In addition, since the mounting plate 8 in this embodiment is horizontally slidably connected to the frame 7, the worker applies a thrust to the mounting plate 8, and the track pulley 10 rolls on the I-rail 9, thereby realizing the horizontal movement of the mounting plate 8, and then changing the horizontal position of the telescopic discharge tube 3 so that the telescopic discharge tube 3 is aligned with the through hole 201.

[0038] To sum up, in this embodiment, the lifting platform 2 can be raised and lowered, and the telescopic discharge pipe 3 can be retracted, so as to adapt to workers of different heights and avoid the lifting platform 2 affecting the transport vehicle entering and exiting the packaging room; moreover, in this embodiment, workers can stand on the lifting platform 2 to load and pack materials without the need for workers to climb onto the transport vehicle, which makes the operation safer and reduces safety hazards.

[0039] Example 2

[0040] The difference between this embodiment and the first embodiment is that: Figure 3 As shown, a storage tank 22 and a mounting base 23 for mounting the storage tank 22 are installed in the upper space. A load cell 24 is fixedly mounted on the mounting base 23 for monitoring the weight of the storage tank 22. In this embodiment, there are four load cells 24, evenly distributed around the circumference of the storage tank 22, thereby more accurately monitoring the weight of the storage tank 22. A feed pipe 25 is connected to the top of the storage tank 22. An electric valve I 26 is installed on the feed pipe 25 for controlling the on / off of the feed pipe 25. The end of the discharge pipe 13, remote from the flexible tube 12, is connected to the bottom of the storage tank 22. An electric valve II 27 is installed on the discharge pipe 13 for controlling the on / off of the discharge pipe 13.

[0041] In this embodiment, material enters the storage tank 22 through the feed pipe 25. The weight of the storage tank 22 is monitored by the weighing sensor 24, and the weight information of the storage tank 22 is transmitted to the PLC controller. When the weight of the storage tank 22 increases to the preset value a, the PLC controller controls the electric valve I 26 to close, thereby stopping the delivery of material to the storage tank 22. After the worker connects the bag opening of the packaging bag to the outlet of the telescopic discharge pipe 3, the electric valve II 27 opens, and the material in the storage tank 22 enters the packaging bag through the discharge pipe 13, the flexible pipe 12, the feed pipe 11, and the telescopic discharge pipe 3. When the weight of the storage tank 22 decreases to the preset value b, the PLC controller controls the electric valve II 27 to close, thereby achieving quantitative loading of the material.

[0042] After electric valve II 27 closes, electric valve I 26 opens, allowing new material to enter storage tank 22 for temporary storage. Load cell 24 continues to monitor the weight of storage tank 22. When the weight of storage tank 22 reaches the preset value a again, the PLC controller controls electric valve I 26 to close. Simultaneously, the worker on lift platform 2 manually knots and seals the bag opening, then places the bag opening back onto the transport vehicle through through-hole 201, completing the material packaging operation. The worker then operates lift platform 2 to ascend and retract telescopic discharge tube 3. Finally, the worker exits lift platform 2 via ladder 4.

[0043] In this embodiment, based on the first embodiment, quantitative charging of materials is also achieved, thereby improving the consistency of the charged products.

[0045] The difference between this embodiment and the first embodiment is that: Figure 4 As shown, the first driving assembly in this embodiment includes four electric hoists 28 , and the four corners of the lifting platform 2 are welded with lifting rings 29 , and the hooks of the four electric hoists 28 are respectively connected to the four lifting rings 29 .

[0046] In this embodiment, the worker controls the electric hoist 28 to achieve the lifting of the lifting platform 2 .
