Description

Technical Field

[0001] This utility model relates to the field of workshop turnover cart technology, specifically to a pressure plate turnover cart for semi-finished vulcanized sheets. Background Technology

[0002] In the vulcanized sheet production process, semi-finished products need to be transferred to subsequent processes via a transfer cart. Traditional transfer carts have a single function, only capable of carrying items, and the vulcanized sheets are prone to wrinkling or deformation due to shaking during transportation. Furthermore, components such as pressure plates and fixing tools need to be stored separately, leading to cumbersome operation and low efficiency. To solve these problems, those skilled in the art have conducted numerous explorations. For example, Chinese Patent CN212828552U discloses a transfer device for metal pipes, which achieves vertical sliding through a telescopic opening on the surface of a guide plate, improving adaptability when pressing metal pipes. However, although this solution integrates multiple functions, it is not suitable for handling flat, semi-finished vulcanized sheets. It is difficult to ensure the stability of the vulcanized sheets during transportation, and the effect of squeezing and flattening the vulcanized sheets is not ideal, requiring further improvement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pressure plate turnover vehicle for semi-finished vulcanized sheets.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A turnover cart for a semi-finished vulcanized sheet includes a cuboid frame, a back guide rail on the back of the cuboid frame, and a metal pressure plate movably mounted on the back guide rail. An extrusion piece for pressing down the metal pressure plate is sleeved on the side of the cuboid frame. Wherein:

[0006] The back rail is vertically mounted on the two metal tubes on the back of the cuboid frame, extending from top to bottom.

[0007] The metal pressure plate is rectangular in shape, with protrusions extending outward at both ends. The protrusions are inserted into the back guide rail and can rotate 180° around the protrusions.

[0008] The extrusion component includes a connecting rod, a vertical screw, and a wrench. One end of the connecting rod is fitted onto the middle metal tube on the side of the cuboid frame, and the other end of the connecting rod is provided with a vertical screw. A wrench is provided at the top of the vertical screw. By rotating the vertical screw with the wrench, the metal pressure plate extruded below the vertical screw is pressed down relative to the metal pressure plate. The vertical screw applies a pre-tightening force to the semi-finished vulcanized sheet below the metal pressure plate.

[0009] This technical solution integrates a metal pressure plate into the interior of a cuboid frame and adds an extrusion component above the metal pressure plate, enriching the functionality of the turnover cart and solving the inconvenience caused by the arbitrary placement of the original components. The bottom of the cuboid frame is also equipped with pulleys for easy turnover. The number or weight of the metal pressure plates can be changed as needed. When the semi-finished vulcanized sheet is placed in the turnover cart, the metal pressure plate is first lowered from the back, then rotated and pressed onto the semi-finished vulcanized sheet. Next, the two extrusion components, which were moved to the outside to avoid interfering with the metal pressure plate's descent, are lifted above the metal pressure plate. The lower end of the vertical screw is then pressed against the upper surface of the metal pressure plate. A wrench is used to rotate the vertical screw until it can no longer be rotated. At this point, the metal pressure plate has applied sufficient pre-tightening force to the semi-finished vulcanized sheet below, thus flattening the originally uneven semi-finished vulcanized sheet after extrusion.

[0010] In addition, the pressure plate turnover cart for semi-finished vulcanized sheets proposed above according to this utility model may also have the following additional technical features:

[0011] According to one embodiment of the present invention, a notch for placing semi-finished vulcanized sheets is provided at the top front of the cuboid frame, and the semi-finished vulcanized sheets are placed within the frame area enclosed by the cuboid frame.

[0012] In this technical solution, the top notch of the cuboid frame is located on the long side, which makes it convenient to put the semi-finished vulcanized sheet directly into the bottom of the cuboid frame from the long side, thereby improving the turnover speed.

[0013] According to one embodiment of the present invention, a hook is provided at the top rear of the cuboid frame, and a folding hanging ring is provided on the side of the metal pressure plate; when the metal pressure plate is to be used, the folding hanging ring is unfolded and suspended on the hook, at which time the metal pressure plate is in a folded state; when the metal pressure plate is to be used, the metal pressure plate is lifted up, the folding hanging ring is removed from the hook, and rotated 90° around the protrusion as the center, so that the metal pressure plate is in a horizontal state, and the metal pressure plate is laid flat on the semi-finished vulcanized sheet below under the action of gravity, and the protrusion gradually moves down along the back guide rail.

[0014] In this technical solution, if the metal pressure plate is normally placed flat at the bottom of the cuboid frame, the operator must lift the metal pressure plate before placing the semi-finished vulcanized sheets. This operation process easily leads to the following problems: the operator needs to expend considerable physical strength to lift multiple heavy semi-finished vulcanized sheets, and if the metal pressure plate is not lifted first, the lifted vulcanized sheets must be put back down before lifting the metal pressure plate again. Therefore, to optimize the operation process and ensure smooth placement of the semi-finished vulcanized sheets, the metal pressure plate must be lifted before operation. The hook is located on the top metal tube and works in conjunction with the folding hanging ring on the metal pressure plate, which is simple and convenient.

[0015] According to one embodiment of the present invention, the connecting rod is in a free state, and the connecting rod drives the vertical screw at its end to rotate freely relative to the middle metal tube; when the metal pressure plate changes from a retracted state to a horizontal state, the connecting rod is manually lifted above the metal pressure plate. At this time, the connecting rod rotates from the outside of the metal pressure plate without interfering with it to the inside. After the height of the metal pressure plate is fixed, a wrench is used to apply a pre-tightening force to the metal pressure plate.

[0016] In this technical solution, since the socket rod rotates or moves up and down along the middle metal tube, in order to avoid the socket rod being unable to move up and down smoothly due to the metal plate being too large, grooves are formed by recessing inward on both sides of the metal pressure plate. The grooves allow the socket rod with a certain thickness to pass through smoothly.

[0017] According to one embodiment of the present invention, two handles are provided on the inner side of the metal pressure plate near the back of the cuboid frame, so that the metal pressure plate can be easily suspended by lifting it.

[0018] In this technical solution, the metal pressure plate is a thick and heavy metal plate, and the handle adopts a hinged style. It is normally in a folded state. When it is necessary to carry it by hand, the handle is pulled up to raise the height of the metal pressure plate, making it easy to hook or remove it from the hook.

[0019] According to one embodiment of the present invention, the cuboid frame is provided with at least one set of metal pressure plates and at least one set of extrusion members.

[0020] In this technical solution, when there are a large number of semi-finished vulcanized sheets, multiple metal pressure plates can be inserted from the back guide rail. In addition to the two sides, extrusion parts can also be added at other angles as needed. It should be noted that all extrusion parts are located only above the top layer of metal pressure plates, while the middle metal pressure plates are filled with semi-finished vulcanized sheets.

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] By integrating the metal pressure plate into the cuboid frame and adding an extrusion component above the metal pressure plate, the functionality of the turnover cart is enriched, solving the inconvenience caused by the random placement of the original parts; the combined action of the metal pressure plate and the extrusion component can apply pre-tightening force to the vulcanized sheet, making it flat after extrusion.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a pressure plate turnover cart for semi-finished vulcanized sheets, including a cuboid frame 1, a back guide rail provided on the back of the cuboid frame 1, and a metal pressure plate 7 movably disposed on the back guide rail. An extrusion component for pressing down is sleeved on the side of the cuboid frame 1 using the auxiliary metal pressure plate 7, wherein:

[0029] The back rail is vertically mounted on the two metal tubes on the back of the cuboid frame 1, extending from top to bottom.

[0030] The metal pressure plate 7 is rectangular in shape, with protrusions extending outward at both ends. The protrusions are inserted into the back guide rail and rotate 180° around the protrusions.

[0031] The extrusion component includes a sleeve rod 3, a vertical screw 4, and a wrench 5. One end of the sleeve rod 3 is sleeved on the middle metal tube on the side of the cuboid frame 1, and the other end of the sleeve rod 3 is provided with a vertical screw 4. A wrench 5 is provided on the top of the vertical screw 4. By rotating the vertical screw 4 with the wrench 5, the metal pressure plate 7 extruded below the vertical screw 4 is pressed down relative to the metal pressure plate 7. The vertical screw 4 applies a pre-tightening force to the semi-finished vulcanized sheet below the metal pressure plate 7.

[0032] like Figure 1 and Figure 2As shown, this technical solution integrates the metal pressure plate 7 into the interior of the cuboid frame 1 and adds an extrusion component above the metal pressure plate 7, enriching the functionality of the turnover cart and solving the inconvenience caused by the random placement of the original parts. The bottom of the cuboid frame 1 is also equipped with pulleys 9 for easy turnover; the number or weight of the metal pressure plates 7 can be changed as needed. When the semi-finished vulcanized sheet is placed in the turnover cart, the metal pressure plate 7 is first lowered from the back, then rotated and pressed onto the semi-finished vulcanized sheet. Next, the two extrusion components, which were moved to the outside to avoid interfering with the falling of the metal pressure plate 7, are lifted above the metal pressure plate 7. The lower end of the vertical screw 4 is then pressed against the upper surface of the metal pressure plate 7. The vertical screw 4 is rotated using a wrench 5 until it can no longer be rotated. At this point, the metal pressure plate 7 has applied sufficient pre-tightening force to the semi-finished vulcanized sheet below, thus making the originally uneven semi-finished vulcanized sheet flat after extrusion.

[0033] In addition, the pressure plate turnover cart for semi-finished vulcanized sheets proposed above according to this utility model may also have the following additional technical features:

[0034] According to one embodiment of the present invention, a notch for placing semi-finished vulcanized sheets is provided at the top front of the cuboid frame 1, and the semi-finished vulcanized sheets are placed within the frame area enclosed by the cuboid frame 1.

[0035] In this technical solution, the top notch of the cuboid frame 1 is located on the long side, which makes it convenient to put the semi-finished vulcanized sheet directly into the bottom of the cuboid frame 1 from the long side, thereby improving the turnover speed.

[0036] According to one embodiment of the present invention, a hook 6 is provided at the rear top of the cuboid frame 1, and a folding hanging ring 8 is provided on the side of the metal pressure plate 7. When the metal pressure plate 7 is to be used, the folding hanging ring 8 is unfolded and suspended on the hook 6, at which time the metal pressure plate 7 is in a folded state. When the metal pressure plate 7 is to be used, the metal pressure plate 7 is lifted up, the folding hanging ring 8 is removed from the hook 6, and rotated 90° around the protrusion as the center, so that the metal pressure plate 7 is in a horizontal state. Under the action of gravity, the metal pressure plate 7 is laid flat on the semi-finished vulcanized sheet below, and the protrusion gradually moves down along the back guide rail.

[0037] In this technical solution, if the metal pressure plate 7 is normally placed flat at the bottom of the cuboid frame 1, the operator needs to lift the metal pressure plate 7 before placing the semi-finished vulcanized sheets. This operation process is prone to the following problems: the operator needs to expend considerable physical strength to lift multiple heavy semi-finished vulcanized sheets, and if the metal pressure plate 7 is not lifted first, the lifted vulcanized sheets must be put back down before lifting the metal pressure plate 7 again. Therefore, to optimize the operation process and ensure that the semi-finished vulcanized sheets can be placed smoothly, the metal pressure plate 7 needs to be lifted before operation. The hook 6 is located on the top metal tube and works in conjunction with the folding hanging ring 8 on the metal pressure plate 7, which is simple and convenient.

[0038] According to one embodiment of the present invention, the connecting rod 3 is in a free state, and the connecting rod 3 drives the vertical screw 4 located at its end to rotate freely relative to the middle metal tube; when the metal pressure plate 7 changes from a retracted state to a horizontal state, the connecting rod 3 is manually lifted above the metal pressure plate 7. At this time, the connecting rod 3 rotates from the outside of the metal pressure plate 7 without interfering with it. After the height of the metal pressure plate 7 is fixed, the wrench 5 is used to apply a pre-tightening force to the metal pressure plate 7.

[0039] In this technical solution, since the connecting rod 3 rotates or moves up and down along the middle metal tube, in order to avoid the connecting rod 3 being unable to move up and down smoothly due to the metal plate being too large, grooves are formed by recessing inward on both sides of the metal pressure plate 7. The grooves allow the connecting rod 3, which has a certain thickness, to pass through smoothly.

[0040] According to one embodiment of the present invention, two handles are provided on the inner side of the metal pressure plate 7 near the back of the cuboid frame 1, so that the metal pressure plate 7 can be easily suspended by lifting it.

[0041] In this technical solution, the metal pressure plate 7 is a relatively thick metal plate, and the handle adopts a hinged style. It is normally in a folded state. When it is necessary to carry it by hand, the handle is pulled up to raise the metal pressure plate 7, making it easy to hook or remove it from the hook 6.

[0042] According to one embodiment of the present invention, the cuboid frame 1 is provided with at least one set of metal pressure plates 7 and at least one set of extrusion members.

[0043] In this technical solution, when there are a large number of semi-finished vulcanized sheets, multiple metal pressure plates 7 can be inserted from the back guide rail. In addition to the two sides, extrusion parts can be added as needed. It should be noted that all extrusion parts are located only above the top layer of metal pressure plate 7, while the middle metal pressure plate 7 is surrounded by semi-finished vulcanized sheets.

[0044] The usage process of the above embodiments is as follows:

[0045] like Figure 1 and Figure 2 As shown, first observe the state of the metal pressure plate 7, and ensure that the metal pressure plate 7 is in a folded state by hanging it on the hook 6 at the top rear of the frame through the folding hanging ring 8; then move the turnover cart to the semi-finished vulcanized sheet that has just been produced through the pulley 9; rotate the extrusion part outward to avoid affecting the placement of the semi-finished vulcanized sheet and to prevent the metal pressure plate 7 from falling.

[0046] like Figure 1 and Figure 2 As shown, the semi-finished vulcanized sheet is placed into the frame through the front notch at the top of the cuboid frame 1;

[0047] Then, lift the metal pressure plate 7 through the inner handle, remove the folding hanging ring 8, rotate it 90° around the protrusion to make it horizontal, and under the action of gravity, the protrusion moves down along the back guide rail, and finally the metal pressure plate 7 will be laid flat on the semi-finished vulcanized sheet.

[0048] Next, the connecting rod 3, which is fitted onto the middle metal tube on the side of the frame, is lifted above the metal pressure plate 7. Since it can rotate freely, it is rotated from the outside to the inside to a suitable position. Then, the vertical screw 4 is rotated using the wrench 5 so that its lower end touches the upper surface of the metal pressure plate 7 and continues to rotate, applying a pre-tightening force to the vulcanized sheet below, so that the uneven semi-finished vulcanized sheet becomes flat.

[0049] If there are many vulcanized sheets, multiple metal pressure plates 7 can be inserted from the back guide rail. Extrusion parts can be added as needed above the highest metal pressure plate 7, and the number or weight of the metal pressure plates 7 can be changed.

[0050] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
