Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a trolley with storage function. Background Technology

[0002] With the development and progress of the manufacturing industry, the demand for packaging equipment is increasing. Fully automatic packaging machines are widely used in industries such as food, pharmaceuticals, hardware, chemicals, clothing, and postal services, and can automatically package and bundle goods of various sizes from all walks of life. Although fully automatic packaging machines can automate the packaging process, the packaging materials on them still require manual loading and unloading. Workers need to transport the packaging materials to the vicinity of the fully automatic packaging machine and then load them onto it. However, since the packaging materials are usually in rolls, they are inconvenient to handle, and other tools are required during the packaging process, leading to a chaotic arrangement of items in the workshop.

[0003] According to the publicly disclosed publication number "CN218489713U", an auxiliary positioning component for a packaging material transport trolley includes a frame, a transport plate, pulleys and a pressure plate, wherein the transport plate is installed on the right side of the frame. By using a combination of a pressure plate, limiting holes, a transport plate, and a fixing mechanism, the pressure plate is pulled upwards. It slides through the limiting holes and support holes onto the surfaces of the limiting rods and support rods until it leaves their surfaces. The items to be transported are then placed on top of the transport plate. The pressure plate is then reset, and the support rods and limiting rods enter the cavities of the limiting holes and support holes. The pressure plate then contacts the transported items, and the fixing mechanism limits its position. While this solves the problem that most existing transport trolleys simply place the transported materials directly on the trolley frame without positioning, leading to tilting and collapse when the trolley shakes or is impacted, this patent uses a fixing mechanism to compress and fix the packaging material. This can easily cause the rolled packaging material to deform under pressure, resulting in entanglement during discharge and affecting the normal operation of the fully automatic packaging machine. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a trolley with storage function, which solves the problem of messy placement of items in the workshop due to the fact that packaging materials are usually rolled up, making them inconvenient to move, and that other tools are needed during the packaging process.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a trolley with a storage function, comprising a movable base plate and a plurality of mounting shafts mounted on the bottom surface of the movable base plate. Each of the mounting shafts has a fixed frame mounted on its bottom surface. Movable wheels are movably mounted inside the fixed frames. A tool storage mechanism is mounted on the top surface of the movable base plate, used to store the tools required for packaging. A limiting mechanism is mounted on the top surface of the movable base plate outside the tool storage mechanism, used to fix the tool storage mechanism to the top surface of the movable base plate to facilitate its synchronous movement with the movable base plate. A plurality of support shafts are mounted on the top surface of the movable base plate, a fixed plate is mounted on the top surface of the support shafts, and a stacking mechanism is mounted on the top surface of the fixed plate, used to prevent packaging materials from falling off during transportation.

[0008] As a preferred embodiment of the present invention, two vertical shafts are installed on the top surface of the fixed plate, and horizontal handrails are installed on the top surfaces of the two vertical shafts. A reinforcing guard plate is installed between the two vertical shafts. By having an operator hold the horizontal handrails, the trolley can be moved as a whole by using the moving wheels, thereby moving the trolley into the packaging material warehouse.

[0009] As a preferred embodiment of the present invention, the tool storage mechanism includes a storage component and an opening and closing component. The storage component is mounted on the top surface of the movable base plate, and the opening and closing component is mounted on the outer surface of the support shaft.

[0010] As a preferred embodiment of the present invention, the storage component includes a storage box and partitions. The storage box is installed on the top surface of the movable base plate. A plurality of partitions are evenly distributed on the inner wall of the storage box, and a storage cavity is formed between the partitions and the storage box. The required packing tools are placed into the storage cavity in sequence for storage, which ensures the stability of the packing tools during transportation, facilitates the retrieval and placement of tools, and has a strong storage capacity.

[0011] The top surface of the storage box has two parallel fixed grooves. Sliding long shafts are movably installed on the inner walls of the two fixed grooves. A sealing cover is installed between the two sliding long shafts. The bottom surface of the sealing cover is in contact with the top surface of the storage box.

[0012] As a preferred embodiment of the present invention, the opening and closing assembly includes a rotating shaft and a first magnetic block. The rotating shaft is movably mounted on the outer surface of any support shaft. A fixed horizontal shaft is mounted on the end surface of the rotating shaft. The first magnetic block is mounted on the end surface of the fixed horizontal shaft. A second magnetic block is mounted on the end surface of the sliding long shaft adjacent to the first magnetic block. When the rotating shaft is twisted by 90 degrees, the first magnetic block and the second magnetic block coincide with each other. Since the corresponding surfaces of the first magnetic block and the second magnetic block have the same magnetism, the sliding long shaft moves along the fixed groove under the action of magnetic repulsion, thereby separating the sealing cover from the storage box.

[0013] A fixed support shaft is movably installed on the outer surface of the storage box. A limit block is installed on the top surface of the fixed support shaft. The limit block is in contact with the second magnetic block. The contact between the limit block and the second magnetic block causes the sealing cover to move to the end and remain stationary.

[0014] As a preferred embodiment of the present invention, the limiting mechanism includes fixed baffles and movable components. The three fixed baffles are respectively installed on the outer surface of the movable base plate, and the movable components are movably installed on the outer surface of the movable base plate.

[0015] In a preferred embodiment of the present invention, the movable component includes a movable baffle and a positioning convex shaft. The movable baffle is mounted on the outer surface of the movable base plate, and an L-shaped connector is movably mounted on the outer surface of the movable baffle, allowing the movable baffle to separate from the fixed baffle. At this time, the entire storage box can be pushed out along the movable bottom for easy tool organization.

[0016] The L-shaped connector has a limiting groove inside. The positioning cam is installed on the outer surface of the fixed baffle adjacent to the movable baffle. The positioning cam is movably installed with a positioning pin inside. When the storage box needs to be removed as a whole, the positioning pin is pulled out, and then the L-shaped connector and the positioning cam are separated from each other, so that the movable baffle is flipped.

[0017] As a preferred embodiment of the present invention, the stacking mechanism includes a stacking component and a placement component, which are respectively mounted on the top surface of the fixed plate.

[0018] As a preferred embodiment of the present invention, the stacking assembly includes a stacking ramp and a stacking vertical shaft. The stacking ramp is installed on the top surface of the fixed plate. Protective baffles are respectively installed on the outer two sides of the stacking ramp. A moving groove is opened on one side surface of the two protective baffles. A guide shaft is movably installed on the inner wall of each of the two moving grooves. A feeding plate is installed between the two guide shafts. The feeding plate can be lifted so that the feeding plate moves upward along the moving groove, which facilitates the removal of the packaging material at one time, making the storage and retrieval of the packaging material convenient and improving the efficiency of the packaging operation.

[0019] The stacking ramp has several evenly distributed movable slots inside. Several stacking shafts are movably installed on the inner wall of the movable slots. The required packaging materials are inserted into the outside of the stacking shafts in sequence, so that the packaging materials are stacked in sequence according to the inclination angle of the stacking ramp and within the protection range of the protective baffle. Compared with the previous horizontal stacking, the vertical stacking of packaging materials reduces the risk of damage caused by bumps and ensures the integrity of the packaging materials. It saves the space occupied by the previous random stacking of packaging materials, improves the utilization rate of on-site work space, facilitates employees to check before use, and promptly report any defects in the packaging materials. At the same time, it avoids the difficulty in counting the quantity caused by horizontal stacking of packaging materials, and facilitates the counting of packaging materials at any time, ensuring timely and accurate counting.

[0020] An ejector spring is installed between each of the stacking vertical shafts and the movable channel. An electromagnet is installed inside the stacking ramp below the movable channel. A battery slot is installed on one side surface of the stacking ramp, and a storage battery is installed inside the battery slot. The storage battery is electrically connected to the electromagnet. The electromagnet is connected to the circuit so that it becomes magnetic when energized. The stacking vertical shaft is made of iron. Under the action of magnetic attraction, the ejector spring is compressed, and the stacking vertical shaft moves downward along the movable channel, thereby causing the packaging material to roll down the stacking ramp to the discharge plate.

[0021] As a preferred embodiment of the present invention, the storage assembly includes a mounting shaft and storage rings. The two mounting shafts are mounted on the top surface of the fixing plate on one side of the stacking slope block, and the two storage rings are respectively mounted on the outer surface of the mounting shafts. The packaging materials can be pulled out one by one from the stacking shafts, and the packaging materials to be used can be temporarily placed on the storage rings in sequence for easy access. The storage rings can also be used to hang tools.

[0022] Beneficial effects

[0023] The present invention has the following beneficial effects:

[0024] (1) The trolley with storage function inserts the required packaging materials into the outside of the stacking vertical shaft in sequence, so that the packaging materials are stacked in sequence according to the tilt angle of the stacking slope. Compared with the previous horizontal stacking, the vertical stacking method of the packaging materials reduces the risk of damage caused by bumps and collisions, ensures the integrity of the packaging materials, saves the space occupied by the previous random stacking of packaging materials, improves the utilization rate of on-site work space, facilitates employees to check before use, and promptly report any defects in the packaging materials. At the same time, it avoids the difficulty in counting the quantity caused by horizontal stacking of packaging materials, and facilitates the counting of packaging materials at any time, ensuring timely and accurate counting.

[0025] (2) The trolley with storage function is magnetic when the electromagnet is energized. Under the action of magnetic attraction, the ejector spring is compressed, causing the stacking shaft to move downward along the movable channel, so that the packaging material rolls down along the stacking slope to the discharge plate. The discharge plate can be lifted, so that the discharge plate moves upward along the moving channel, making it convenient to remove the packaging material at one time, making the storage and retrieval of the packaging material convenient and improving the efficiency of the packaging operation.

[0026] (3) The trolley with storage function has the same magnetism on the corresponding surfaces of the first and second magnetic blocks. Under the action of magnetic repulsion, the sliding long shaft moves along the fixed slide groove, thereby separating the sealing cover from the storage box. The required packing tools are then placed into the storage cavity for storage, ensuring the stability of the packing tools during transportation, facilitating the retrieval and placement of tools, and having strong storage capacity, thus avoiding the inconvenience caused by the packing tools being scattered.

[0027] (4) When the storage box needs to be removed as a whole, the positioning pin is pulled out and the L-shaped connector is separated from the positioning cam, so that the movable baffle is flipped and the movable baffle is separated from the fixed baffle. At this time, the storage box can be pushed out as a whole along the movable bottom, which is convenient for organizing tools and prevents the packing tools from being lost in the workshop, affecting the work efficiency of the staff.

[0028] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] Please see Figures 1-10This invention provides a technical solution: a trolley with storage function, including a movable base plate 1 and several mounting shafts 2 mounted on the bottom surface of the movable base plate 1. Each mounting shaft 2 has a fixing frame 3 mounted on its bottom surface. Movable wheels 4 are movably mounted inside the fixing frame 3. A tool storage mechanism is mounted on the top surface of the movable base plate 1 to store the tools required for packaging. A limiting mechanism is mounted on the top surface of the movable base plate 1 outside the tool storage mechanism to fix the tool storage mechanism to the top surface of the movable base plate 1, facilitating its synchronous movement with the movable base plate 1. Several support shafts 5 are mounted on the top surface of the movable base plate 1. A fixing plate 6 is mounted on the top surface of the support shafts 5. A stacking mechanism is mounted on the top surface of the fixing plate 6 to prevent packaging materials from falling off during transportation.

[0043] Specifically, two vertical shafts 7 are installed on the top surface of the fixed plate 6, and horizontal handrails 8 are installed on the top surface of the two vertical shafts 7. A reinforcing guard plate 9 is installed between the two vertical shafts 7. The operator holds the horizontal handrails 8 and then pushes the trolley as a whole through the moving wheels 4 to move the trolley into the packaging material warehouse.

[0044] Furthermore, the tool storage mechanism includes a storage component and an opening and closing component. The storage component is installed on the top surface of the movable base plate 1, and the opening and closing component is installed on the outer surface of the support shaft 5.

[0045] Furthermore, the storage component includes a storage box 10 and partitions 11. The storage box 10 is installed on the top surface of the movable base plate 1. Several partitions 11 are evenly distributed on the inner wall of the storage box 10, forming a storage cavity between the partitions 11 and the storage box 10. The required packing tools are placed into the storage cavity for storage, ensuring the stability of the packing tools during transportation, facilitating the retrieval and placement of tools, and providing strong storage capacity.

[0046] The top surface of the storage box 10 has two parallel fixed grooves 12. Sliding long shafts 13 are movably installed on the inner walls of the two fixed grooves 12 respectively. A sealing cover 14 is installed between the two sliding long shafts 13. The bottom surface of the sealing cover 14 is in contact with the top surface of the storage box 10.

[0047] Furthermore, the opening and closing assembly includes a rotating shaft 15 and a first magnetic block 17. The rotating shaft 15 is movably mounted on the outer surface of any support shaft 5. A fixed horizontal shaft 16 is mounted on the end surface of the rotating shaft 15. The first magnetic block 17 is mounted on the end surface of the fixed horizontal shaft 16. A second magnetic block 18 is mounted on the end surface of the sliding long shaft 13 adjacent to the first magnetic block 17. Twisting the rotating shaft 15 causes it to rotate 90 degrees, so that the first magnetic block 17 and the second magnetic block 18 coincide with each other. Since the corresponding surfaces of the first magnetic block 17 and the second magnetic block 18 have the same magnetism, the sliding long shaft 13 moves along the fixed slide groove 12 under the action of magnetic repulsion, thereby separating the sealing cover 14 from the storage box 10.

[0048] A fixed support shaft 19 is movably installed on the outer surface of the storage box 10. A limit block 20 is installed on the top surface of the fixed support shaft 19. The limit block 20 is in contact with the second magnetic block 18. The contact between the limit block 20 and the second magnetic block 18 causes the sealing cover plate 14 to move to the end and remain stationary.

[0049] Furthermore, the limiting mechanism includes fixed baffles 21 and movable components. The three fixed baffles 21 are respectively installed on the outer surface of the movable base plate 1, and the movable components are movably installed on the outer surface of the movable base plate 1.

[0050] Furthermore, the movable components include a movable baffle 22 and a positioning cam 25. The movable baffle 22 is installed on the outer surface of the movable base plate 1, so that the movable baffle 22 is separated from the fixed baffle 21. At this time, the storage box 10 can be pushed out as a whole along the movable bottom, which is convenient for organizing tools.

[0051] An L-shaped connector 23 is movably installed on the outer surface of the movable baffle 22. A limiting groove 24 is opened inside the L-shaped connector 23. A positioning convex shaft 25 is installed on the outer surface of the fixed baffle 21 adjacent to the movable baffle 22. A positioning pin 26 is movably installed inside the positioning convex shaft 25. When the storage box 10 needs to be removed as a whole, the positioning pin 26 is pulled out, and then the L-shaped connector 23 and the positioning convex shaft 25 are separated from each other, so that the movable baffle 22 can be flipped.

[0052] Furthermore, the stacking mechanism includes a stacking assembly and a storage assembly, which are respectively mounted on the top surface of the fixed plate 6.

[0053] Furthermore, the stacking assembly includes a stacking ramp 27 and a stacking vertical shaft 33. The stacking ramp 27 is installed on the top surface of the fixed plate 6. Protective baffles 28 are installed on the outer two sides of the stacking ramp 27. A moving groove 29 is opened on one side surface of the two protective baffles 28. A guide shaft 30 is movably installed on the inner wall of the two moving grooves 29. A feeding plate 31 is installed between the two guide shafts 30. The feeding plate 31 can be lifted so that the feeding plate 31 can move upward along the moving groove 29, making it convenient to remove the packaging material at one time, making the storage and retrieval of the packaging material convenient and improving the efficiency of the packaging operation.

[0054] The interior of the stacking ramp 27 has several evenly distributed movable slots 32, and several stacking vertical shafts 33 are movably installed on the inner wall of the movable slots 32. The required packaging materials are inserted into the outside of the stacking vertical shafts 33 in sequence, so that the packaging materials are stacked in sequence according to the tilt angle of the stacking ramp 27 and within the protection range of the protective baffle 28. Compared with the previous horizontal stacking, the vertical stacking of packaging materials reduces the risk of damage caused by bumps and collisions, ensures the integrity of packaging materials, saves the space occupied by the previous random stacking of packaging materials, improves the utilization rate of on-site work space, facilitates employees to check before use, and promptly report any defects in packaging materials. At the same time, it avoids the difficulty in counting the quantity caused by horizontal stacking of packaging materials, and facilitates the counting of packaging materials at any time, ensuring timely and accurate counting.

[0055] An ejector spring 34 is installed between each stack vertical shaft 33 and the movable channel 32. An electromagnet 35 is installed inside the stacking ramp 27 below the movable channel 32. A battery slot 36 is installed on one side surface of the stacking ramp 27. A storage battery 37 is installed inside the battery slot 36. The storage battery 37 is electrically connected to the electromagnet 35. When the electromagnet 35 is connected to the circuit, it becomes magnetic when energized. The stacking vertical shaft 33 is made of iron. Under the action of magnetic attraction, the ejector spring 34 is compressed, and the stacking vertical shaft 33 moves downward along the movable channel 32, so that the packaging material rolls down the stacking ramp 27 to the discharge plate 31.

[0056] Furthermore, the storage assembly includes a mounting shaft 2 and storage rings 39. Two mounting shafts 38 are mounted on the top surface of the fixing plate 6 on one side of the stacking slope block 27, and two storage rings 39 are respectively mounted on the outer surface of the mounting shafts 38. The packaging materials can be pulled out one by one from the stacking shafts 33, and the packaging materials to be used can be temporarily placed on the storage rings 39 in sequence for easy access. The storage rings 39 can also be used to hang tools.

[0057] During use (work), the operator holds the horizontal handrail 8 and then moves the trolley by pushing the entire trolley with the moving wheels 4, thereby moving the trolley into the packaging material warehouse. The required packaging materials are inserted sequentially on the outside of the stacking vertical shaft 33, and the packaging materials are stacked sequentially according to the inclination angle of the stacking ramp 27, and are within the protection range of the protective baffle 28. Compared with the previous horizontal stacking, the vertical stacking of packaging materials reduces the risk of damage caused by bumps and collisions, ensures the integrity of the packaging materials, saves the space occupied by the previous random stacking of packaging materials, improves the utilization rate of on-site work space, facilitates employees to check before use, and promptly report any defects in the packaging materials. At the same time, it avoids the difficulty in counting the quantity caused by horizontal stacking of packaging materials, and facilitates the counting of packaging materials at any time, ensuring timely and accurate counting.

[0058] The trolley is moved to the fully automatic packing machine, and the packaging materials can be pulled out one by one from the stacking shaft 33. If the packaging materials need to be removed at once, the electromagnet 35 can be connected to the circuit so that the electromagnet 35 is energized and becomes magnetic. The stacking shaft 33 is made of iron material. At this time, under the action of magnetic attraction, the ejection spring 34 is compressed, and the stacking shaft 33 moves downward along the movable channel 32, so that the packaging materials roll down along the stacking ramp 27 to the discharge plate 31. The discharge plate 31 can be lifted so that the discharge plate 31 moves upward along the moving channel 29, which makes it convenient to remove the packaging materials at once, making the storage and retrieval of packaging materials convenient and improving the efficiency of packing operation.

[0059] The rotating shaft 15 is rotated 90 degrees, causing the first magnetic block 17 and the second magnetic block 18 to overlap. Since the corresponding surfaces of the first magnetic block 17 and the second magnetic block 18 have the same magnetism, the sliding long shaft 13 moves along the fixed slide groove 12 under the action of magnetic repulsion, thereby separating the sealing cover 14 from the storage box 10. The required packing tools are then placed into the storage cavity for storage. The contact between the limiting block 20 and the second magnetic block 18 causes the sealing cover 14 to move to the end and remain stationary. Then the rotating shaft 15 is reset, at which point the magnetic repulsion disappears, and the sealing cover 14 is pushed back, ensuring the stability of the packing tools during transportation, facilitating the retrieval and placement of tools, and providing strong storage capacity.

[0060] When the storage box 10 needs to be removed as a whole, pull out the positioning pin 26, and then separate the L-shaped connector 23 from the positioning cam 25, so that the movable baffle 22 is flipped, thereby separating the movable baffle 22 from the fixed baffle 21. At this time, the storage box 10 can be pushed out as a whole along the movable bottom for easy tool organization.
