Description

Technical Field

[0001] This utility model relates to a cantilever winding machine for plastic sheets, belonging to the technical field of plastic sheet extrusion production equipment. Background Technology

[0002] In the production of plastic sheets, the winding machine is one of the key pieces of equipment. It is responsible for winding the continuous plastic sheet extruded from the extruder into a roll for storage, transportation, and further processing. The performance of the winding machine directly affects the quality of the finished product, production efficiency, and ease of operation. A search revealed that Chinese patent CN221720199U discloses a cantilever winding machine for plastic sheets. In this patent, the air shaft is already mounted on the frame. Rotating the handle drives the rotating rod to rotate, which in turn transmits power through the meshing of bevel gear one and bevel gear two. This causes the two screws to rotate synchronously, driving the slider to move and pushing the inner tube axially within the groove. As the inner tube moves axially, one end of the inner tube moves outward from the outer tube. Since the other end of the inner tube is always outside the outer tube, the expansion and contraction of the inner tube causes its outer end to expand outward. When the outer diameter of the air shaft increases to a size that matches the inner diameter of the roll material, the roll material is placed on the air shaft. After winding is complete, rotating the handle in the opposite direction causes the screw to drive the slider to move in the opposite direction, causing the inner tube to contract. The outer diameter of the air shaft decreases, and the roll material can be easily removed from the air shaft. However, in this patent, the air shaft winding method cannot effectively remove thick plastic sheets, and custom-made air shafts would increase production costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a cantilever winding machine for plastic sheets, which can effectively wind sheet products, has wide applicability, and is easy to operate.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cantilever winding machine for plastic sheets, comprising:

[0005] Support frame;

[0006] A working spindle, which is rotatably mounted on the support frame;

[0007] A winding assembly, the winding assembly including a mounting base, the mounting base being mounted on the working spindle, and at least two winding blades being evenly arranged circumferentially on the mounting base with the center of the mounting base as the center;

[0008] An adjustment assembly, comprising an adjustment bearing housing, an adjustment screw, and an adjustment seat, wherein the adjustment bearing housing is connected to one end of the working spindle, the adjustment screw is installed in the adjustment bearing housing, and the adjustment seat is installed on the adjustment screw;

[0009] One end of the winding blade is hinged to the mounting base, and the other end of the winding blade is hinged to the adjusting base through a connecting assembly. Rotating the adjusting screw drives the adjusting base to move, thereby changing the relative position between the winding blade and the working spindle, thus realizing the adjustment of the winding diameter.

[0010] A drive assembly adapted to drive the working spindle to rotate so as to drive the winding assembly to wind up.

[0011] Furthermore, to better secure the plastic sheet and prevent it from slipping or loosening during winding, one of the winding blades is provided with a fixing groove suitable for securing the plastic sheet, the opening of which faces away from the winding direction.

[0012] Furthermore, a handwheel suitable for operation is installed at one end of the adjusting screw.

[0013] Furthermore, in order to allow the winding blades to swing freely within a certain range to change the winding diameter, the connecting assembly includes a connecting plate and two connecting pins. The connecting plate is provided with a first connecting groove and a second connecting groove. The connecting plate is also provided with a first connecting hole and a second connecting hole. The first connecting hole communicates with the first connecting groove, and the second connecting hole communicates with the second connecting groove.

[0014] The winding blade is provided with a first connecting part, and the first connecting part is provided with a third connecting hole. The adjusting seat is provided with at least one second connecting part, and the second connecting part is provided with a fourth connecting hole. One of the connecting pins passes through the first connecting hole and the third connecting hole to install the first connecting part in the first connecting groove, and the other connecting pin passes through the second connecting hole and the fourth connecting hole to install the second connecting part in the second connecting groove.

[0015] Furthermore, the drive assembly includes a drive motor, a drive sprocket, a driven sprocket, and a synchronization chain. The drive motor is mounted on the support frame. The drive sprocket is connected to the movable end of the drive motor. The driven sprocket is coaxially arranged with the working spindle. The synchronization chain is adapted to connect the drive sprocket and the driven sprocket.

[0016] Furthermore, a connecting bearing seat is provided between the support frame and the working spindle.

[0017] Furthermore, in order to ensure the tension of the synchronization chain, the cantilever winding machine for plastic sheets also includes a tensioning assembly, which includes a tensioning shaft and a tensioning wheel. The support frame is provided with a waist hole, the tensioning shaft passes through the waist hole and is installed on the support frame through at least one fastening nut, and the tensioning wheel is installed on the tensioning shaft. The tensioning wheel is adapted to contact the synchronization chain.

[0018] After adopting the above technical solution, this utility model has the following beneficial effects:

[0019] In this invention, the produced plastic sheet is inserted into the fixed slot to ensure that the plastic sheet will not come loose during the winding process. The adjusting seat is moved by rotating the handwheel to make the winding blade parallel to the working spindle.

[0020] Start the drive motor, which drives the drive sprocket and driven sprocket to rotate via the synchronous chain, thereby driving the working spindle and winding blade to rotate. As the working spindle rotates, the winding blade begins to wind up the plastic sheet.

[0021] After winding is complete, stop the drive motor and move the adjusting seat by rotating the handwheel in the opposite direction. This will bring one end of the winding blade close to the working spindle to form an angle, making the winding blade and the working spindle triangular. This will loosen the wound plastic sheet and make it easier to remove it from the winding machine. Attached Figure Description

[0027] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] like Figure 1-5 As shown, a cantilever winding machine for plastic sheets includes:

[0029] Support frame 1;

[0030] The working spindle 2 is rotatably mounted on the support frame 1;

[0031] The winding assembly includes a mounting base 31, which is mounted on the working spindle 2. Four winding blades 32 are evenly arranged circumferentially around the center of the mounting base 31.

[0032] The adjustment assembly includes an adjustment bearing housing 41, an adjustment screw 42, and an adjustment seat 43. The adjustment bearing housing 41 is connected to one end of the working spindle 2. The adjustment screw 42 is installed in the adjustment bearing housing 41, and the adjustment seat 43 is installed on the adjustment screw 42.

[0033] One end of the take-up blade 32 is hinged to the mounting base 31, and the other end of the take-up blade 32 is hinged to the adjusting base 43 through the connecting assembly. Rotating the adjusting screw 42 drives the adjusting base 43 to move to change the relative position between the take-up blade 32 and the working spindle 2, thereby realizing the adjustment of the take-up diameter.

[0034] The drive assembly is adapted to drive the working spindle 2 to rotate so as to drive the winding assembly to wind.

[0035] In this embodiment, the winding blade 32 is arc-shaped, and the four winding blades 32 together form a circle.

[0036] Specifically, such as Figure 1-3 As shown, one of the winding blades 32 is provided with a fixing groove 321 suitable for fixing the plastic sheet, and the groove opening of the fixing groove 321 faces away from the winding direction.

[0037] Specifically, such as Figure 1-3 As shown, a handwheel 421 suitable for operation is installed at one end of the adjusting screw 42.

[0038] Specifically, such as Figure 5 As shown, the connecting assembly includes a connecting plate 51 and two connecting pins 52. The connecting plate 51 is provided with a first connecting groove 511 and a second connecting groove 512. The connecting plate 51 is also provided with a first connecting hole and a second connecting hole. The first connecting hole communicates with the first connecting groove 511, and the second connecting hole communicates with the second connecting groove 512.

[0039] The winding blade 32 is provided with a first connecting part 322, and the first connecting part 322 is provided with a third connecting hole. The adjusting seat 43 is provided with at least one second connecting part 431, and the second connecting part 431 is provided with a fourth connecting hole. One connecting pin 52 passes through the first connecting hole and the third connecting hole to install the first connecting part 322 in the first connecting groove 511, and another connecting pin 52 passes through the second connecting hole and the fourth connecting hole to install the second connecting part 431 in the second connecting groove 512.

[0040] In this embodiment, rotating the handwheel 421 drives the adjusting screw 62 to rotate in the forward or reverse direction, which in turn drives the adjusting seat 63 to move toward the handwheel 421. The movement of the adjusting seat 63 drives the winding blade 32 to move downward through the connecting component. At this time, a certain angle is formed between the winding blade and the working spindle 2, which reduces the winding diameter and makes it easier to remove the plastic sheet wrapped on the winding blade.

[0041] Conversely, rotating the handwheel 421 drives the adjusting screw 62 to rotate in the forward or reverse direction, causing the adjusting seat 63 to move away from the handwheel 421. The movement of the adjusting seat 63 drives the winding blade 32 to move upward through the connecting assembly. At this time, the winding blade is parallel to the working spindle 2, which increases the winding diameter, and the winding operation can then be performed.

[0042] Specifically, such as Figure 1-4 As shown, the drive assembly includes a drive motor 61, a drive sprocket 62, a driven sprocket 63, and a synchronous chain 64. The drive motor 61 is mounted on the support frame 1. The drive sprocket 62 is connected to the movable end of the drive motor 61. The driven sprocket 63 is coaxially arranged with the working spindle 2. The synchronous chain 64 is adapted to connect the drive sprocket 62 and the driven sprocket 63.

[0043] In this embodiment, the drive motor 61 drives the drive sprocket 62 to rotate clockwise. Since the synchronous chain 64 connects the drive sprocket 62 and the driven sprocket 63, the driven sprocket 63 also rotates clockwise, driving the working spindle 2 to rotate clockwise to wind up the plastic sheet.

[0044] Specifically, such as Figure 1-3 As shown, a connecting bearing seat 7 is provided between the support frame 1 and the working spindle 2. The connecting bearing seat 7 is configured to provide stable support for the working spindle 2 and ensure its smooth rotation.

[0045] Specifically, such as Figure 4 As shown, the cantilever winding machine for plastic sheets also includes a tensioning assembly, which includes a tensioning shaft 81 and a tensioning wheel 82. The support frame 1 is provided with a waist hole 11. The tensioning shaft 81 passes through the waist hole 11 and is installed on the support frame 1 by at least one fastening nut. The tensioning wheel 82 is installed on the tensioning shaft 81 and is adapted to contact the synchronous chain 64.

[0046] In this embodiment, the fastening nut can be tightened or loosened to facilitate the movement of the tensioning shaft 81 to adjust its position in the waist hole 11. The tensioning wheel 82 is a tensioning sprocket. By adjusting the position of the tensioning wheel 82, different levels of pressure are applied to the synchronous chain 64 to change the tension of the synchronous chain 64, thereby adjusting the winding tension of the plastic sheet.

[0047] The working principle of the above embodiment is as follows: the produced plastic sheet is inserted into the fixed slot 321 to ensure that the plastic sheet will not come loose during the winding process. The adjusting seat 43 is moved by rotating the handwheel 421 so that the winding blade 32 is parallel to the working spindle 2.

[0048] Start the drive motor 61, which drives the drive sprocket 62 and the driven sprocket 63 to rotate through the synchronous chain 64, thereby driving the working spindle 2 and the winding blade 32 to rotate. As the working spindle 2 rotates, the winding blade 32 begins to wind up the plastic sheet.

[0049] After winding is completed, stop the drive motor 61 and move the adjusting seat 43 by rotating the handwheel 421 in the opposite direction, so that one end of the winding blade 32 is close to the working main shaft 2 to form an angle, so that the winding blade 32 and the working main shaft 2 form a triangle, which loosens the wound plastic sheet and makes it easy to remove it from the winding machine.

[0050] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
