Description

Technical Field

[0001] This utility model relates to the field of sheet material transportation, specifically a transportation device for PP sheet material production. Background Technology

[0002] As a lightweight, high-strength, and chemically stable polypropylene material, PP sheets are in high demand in packaging, construction, electronics and other fields. However, they are susceptible to temperature, humidity and physical impact during transportation, which can lead to deformation or performance degradation.

[0003] Currently, when PP sheets are transferred in the production workshop, transport vehicles are generally used to transport the PP sheets between various production lines within the workshop.

[0004] When using transport vehicles, workers typically need to stack PP sheets layer by layer on the transport vehicle. However, due to the smooth nature of PP sheets, slippage can occur between the upper and lower PP sheets during the stacking process, causing the stack to shift. This requires workers to make multiple adjustments during the stacking process, reducing the overall stacking efficiency and affecting the overall production speed. Utility Model Content

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

[0015] This invention features a calibration assembly. Under the weight of the PP sheet, the working plate presses downwards against the frustum, thereby causing multiple connecting rods to stretch and move sequentially. This stretches the long rods, causing the calibration rods to move inwards. The four calibration rods then press multiple PP sheets inwards, achieving the calibration effect. Simultaneously, several protrusions are provided on the inner wall of the calibration rods, increasing the friction between the PP sheets and the rods and preventing the PP sheets from slipping backwards, further ensuring transportation safety.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] Please see Figures 1 to 5 This utility model provides a transport device for PP sheet production, including a base 1, a back plate 3 connected to one end of the base 1, a handle 4 connected to the top of the back plate 3, and further including:

[0029] A calibration component 2 is provided above the base 1. The calibration component 2 includes a working plate 213. A frustum groove 21 is provided at the bottom of the working plate 213. The frustum groove 21 is opened on the upper surface of the base 1. A first connecting rod 25 is provided inside the frustum groove 21. A second connecting rod 26 is movably connected to one end of the first connecting rod 25. A third connecting rod 27 is movably connected to one end of the second connecting rod 26. A long rod 28 is movably connected to one end of the third connecting rod 27. A calibration rod 24 is movably connected to one end of the long rod 28. A connecting block 29 is movably connected to the other end of the first connecting rod 25. A telescopic rod 210 is movably connected to the lower end of the connecting block 29. A first spring 211 is movably connected to the outer surface of the telescopic rod 210. The lower end of the telescopic rod 210 is fixedly connected to the inside of the frustum groove 21. A frustum 212 is fixedly connected to the upper end of the connecting block 29. The working plate 213 is fixedly connected to the upper end of the frustum 212.

[0030] In the PP sheet production workshop, PP sheets sometimes need to be transferred between production lines. Workers place the PP sheets to be transferred onto the work plate 213 in sequence. After the work plate 213 is subjected to the weight pressure of the PP sheets, the truncated cone 212 below the work plate 213 presses down on the connecting block 29. The connecting block 29 compresses the telescopic rod 210 and the first spring 211 downwards. At the same time, the connecting block 29 pushes down and drives the first connecting rod 25 to move. The first connecting rod 25 is pulled down and stretches the second connecting rod 26. After the second connecting rod 26 is subjected to force, it stretches the third connecting rod 27. After the third connecting rod 27 is subjected to force, it stretches the long rod 28. After the long rod 28 is subjected to force, it pulls the calibration rod 24 to slide inwards. The two pairs of calibration rods 24 on the work plate 213 move relative to each other under the weight of the PP sheets, performing a reset calibration operation on the PP sheets that the workers have placed randomly, preventing the PP sheets from falling during the transfer process.

[0031] For details, please refer to Figure 2 and Figure 5 A long rod groove 22 is provided on one side of the truncated cone groove 21, and a side groove 23 is provided at one end of the long rod groove 22. The long rod 28 is set inside the long rod groove 22, and one end of the calibration rod 24 is slidably set in the side groove 23. The long rod 28 and the calibration rod 24 are fixedly connected.

[0032] A frustum groove 21 is made on the base 1, and a frustum 212 is set below the working plate 213 to leave a suitable moving space between the working plate 213 and the base 1, so that the working plate 213 can be pressed down according to the weight of the PP sheet. The setting of the long rod groove 22 also leaves enough room for the long rod 28 to move. A side groove 23 is also made on the edge of the base 1 for the movement of the calibration rod 24. At the same time, the frustum groove 21, the long rod groove 22 and the side groove 23 are interconnected.

[0033] For details, please refer to Figure 2 , Figure 3 and Figure 5The lower end of the frustum 212 is movably connected to the top of the frustum groove 21. Displacement grooves 214 are provided on both sides of the working plate 213. The calibration rod 24 passes through the displacement grooves 214 and extends to the upper end of the working plate 213.

[0034] A frustum 212 is set under the working plate 213, and the lower end of the frustum 212 is aligned with the top end of the frustum groove 21, so that the working plate 213 and the base 1 are aligned to avoid misalignment. Displacement grooves 214 are provided on both sides of the working plate 213 to provide displacement space for the calibration rod 24, which facilitates the calibration and reset operation.

[0035] For details, please refer to Figure 1 and Figure 4 A connector 5 is fixedly connected to one end of the back plate 3, and a rotating rod 6 is connected through the inner side of the connector 5. The back plate 3 is movably connected to the base 1 through the rotating rod 6.

[0036] The back plate 3 is movably connected to the base 1 using connector 5 and rotating rod 6, so that the back plate 3 can rotate around the rotating rod 6 as the axis.

[0037] For details, please refer to Figure 1 and Figure 8 A locking assembly 7 is fixedly connected to one side of the outer surface of the base 1. The locking assembly 7 includes a fixing rod 71. One end of the fixing rod 71 is movably connected to a first locking pin 72, and the other end of the fixing rod 71 is movably connected to a second locking pin 73. An arc-shaped groove 77 is connected through the end of the fixing rod 71 away from the first locking pin 72.

[0038] A locking assembly 7 is provided on one side of the base 1 and the outer surface, which fixes the fixing rod 71 by two locking pins. At the same time, an arc-shaped groove 77 is connected through the end away from the first locking pin 72, which provides an outlet for the second locking pin 73.

[0039] For details, please refer to Figure 1 and Figure 8 The first locking pin 72 is configured as a T-shaped structure with a larger top and a smaller bottom. The lower end of the first locking pin 72 is fixedly connected to one side of the outer surface of the base 1. The lower end of the second locking pin 73 is fixedly connected to one side of the outer surface of the back plate 3. The second locking pin 73 is configured as a T-shaped structure with a larger top and a smaller bottom. The diameter of the lower end of the second locking pin 73 is the same as the width of the arc groove 77.

[0040] The first locking pin 72 is fixed to one side of the outer surface of the base 1, and the second locking pin 73 is fixed to one side of the outer surface of the back plate 3. They are then connected by a fixing rod 71. The purpose is to fix the base 1 and the back plate 3 in place and prevent the back plate 3 from loosening during the transfer of PP sheets. At the same time, the T-shaped locking pin structure design, which is larger at the top and smaller at the bottom, also effectively restricts the lower end of the locking pin to the fixing rod 71 and prevents the fixing rod 71 from falling off.

[0041] For details, please refer to Figure 1 and Figure 8 One end of the fixed rod 71 is fitted with a movable groove 74 corresponding to the arc-shaped groove 77. A second spring 75 is movably connected inside the movable groove 74, and a limit block 76 is fixedly connected to the top of the movable groove 74.

[0042] A movable groove 74 is installed at one end of the fixed rod 71 corresponding to the arc-shaped groove 77, providing a foundation for installing the limit block 76 assembly. A second spring 75 is installed in the movable groove 74 to support the reset limit block 76.

[0043] For details, please refer to Figure 1 and Figure 8 The limiting block 76 is an inverted T-shape that is wider at the top and narrower at the bottom. One side of the limiting block 76 passes through the movable groove 74 and extends into the arc-shaped groove 77. The limiting block 76 extends to the end of the arc-shaped groove 77 and one end of the limiting block 76 is set to be arc-shaped.

[0044] The limiting block 76 is set as an inverted T-shape with a wider top and a narrower bottom, so that the wider end of the limiting block 76 is stuck in the movable groove 74, while the narrower end is set as an arc shape to correspond to the arc of the arc groove 77, which is more conducive to fixing the second locking pin 73 and prevents the risk of the fixing rod 71 falling off due to bumps during transportation.

[0045] For details, please refer to Figure 6 and Figure 7 A damping assembly 8 is fixedly connected to one side of the calibration rod 24. The damping assembly 8 includes a calibration protrusion 81, which is installed inside the calibration rod 24. Several slots 82 are provided on the protrusion 81. A flat surface 83 is provided on the side of the protrusion 81 that is parallel to the calibration rod 24. A curved surface 84 is provided on the inner side of the protrusion 81.

[0046] A damping component 8 is set on one side of the calibration rod 24 to increase the friction of the PP sheet contact surface and prevent the PP sheet from falling. The protrusion 81 is made of soft plastic to protect the edge of the PP sheet from wear. The setting of one side of the protrusion 81 being a flat surface 83 and the inside being a curved surface 84 also prevents the PP sheet from falling backward. The slot 82 is also set to isolate the PP sheets and prevent wear on the contact surface between the PP sheets.

[0047] The specific procedure is as follows: The operator places PP sheets sequentially on the work plate 213. The work plate 213, compressed by the PP sheets, transmits its weight downwards. This force is then transmitted to the frustum 212 via the telescopic rod 210 and the first spring 211. The frustum 212 compresses downwards, causing it to press down on the connecting block 29. The connecting block 29 then moves the first connecting rod 25, which straightens downwards and stretches the second connecting rod 26. The second connecting rod 26, under pressure, stretches the third connecting rod 27. The third connecting rod 27, under pressure, stretches the long rod 28. The long rod 28, under pressure, pulls the calibration rod 24 towards... The calibrators slide inward, causing the calibration rods 24 on both sides of the upper surface of the work plate 213 to move relative to each other. This pushes the PP sheet on the work plate 213 inward to achieve the calibration effect and ensure the safety of transporting the PP sheet. At the same time, when it is necessary to unload the PP sheet, the fixing rod 71 is rotated around the first locking pin 72, causing the second locking pin 73 at one end of the fixing rod 71 connected to the back plate 3 to fall out of the arc groove 77. This eliminates the fixing effect of the fixing rod 71 on the back plate 3. Pull the handle 4 to place the back plate 3 horizontally with the base 1, and then remove the PP sheets one by one.
