Description

Technical Field

[0001] This utility model relates to the field of pearl cotton board production technology, and in particular to a winding device for foam pearl cotton board. Background Technology

[0002] The winding device for foam pearl cotton board (EPE pearl cotton) is a specialized mechanical equipment mainly used to automatically or semi-automatically wind continuously produced sheet or board pearl cotton material into neat rolls. It can effectively ensure the tightness and flatness of the winding, which facilitates subsequent transportation, storage and processing. Its design needs to take into account factors such as material thickness, width and production speed, and it is widely used in packaging, construction, electronics and other fields.

[0003] Existing foam pearl cotton board winding devices have obvious design flaws. The main problem is the lack of an effective limiting and anti-rotation structure for the winding roller. In actual operation, when the pearl cotton board is dragged by external force, this design flaw will cause the winding roller to rotate unexpectedly. This rotation will not only cause material loosening and interlayer misalignment, but also seriously affect the neatness and tightness of winding, ultimately leading to a decline in product quality.

[0004] Therefore, to address the problem that existing foam pearl cotton board winding devices lack a limiting and anti-rotation structure for the winding roller, and that the winding roller will rotate if the pearl cotton board is dragged during winding, thus affecting the winding quality, a new foam pearl cotton board winding device can be designed. Utility Model Content

[0005] To overcome the problem that existing foam pearl cotton board winding devices lack a limiting and anti-rotation structure for the winding roller, which causes the winding roller to rotate if the pearl cotton board is dragged during winding, thus affecting the winding quality.

[0006] The technical solution of this utility model is as follows: a winding device for foam pearl cotton board, including a mounting frame; and a ratchet gear. A first drive shaft is rotatably connected to the front inside of the mounting frame, a second drive shaft is rotatably connected to the rear inside of the mounting frame, and a winding roller is rotatably connected to the lower inside of the mounting frame. A rotating component is provided on the left side of the mounting frame corresponding to the position of the first drive shaft. The rotating component is used to drive the first drive shaft to rotate. A linkage component is provided on the three drive shafts. A fixing rod is fixed on the upper inside of the mounting frame, and a connecting rod is fixed on the outer side of the fixing rod. The connecting rod is rotatably connected to the first drive shaft. A limiting pawl is installed on the right outer end of the fixing rod. A turntable is installed on the right outer end of the second drive shaft. A ratchet gear is connected to the turntable. The limiting pawl engages with the ratchet gear. A limiting mechanism is provided on the right inside of the mounting frame, and a positioning component is provided on the outer side of the turntable.

[0007] Preferably, a rotating component is provided to drive the first drive shaft to rotate. Under the action of the linkage component, the second drive shaft and the take-up roller rotate synchronously. When the second drive shaft rotates, it drives the turntable and the ratchet to rotate. The teeth of the ratchet will engage with the limiting pawl in sequence to limit the ratchet's rotation, thereby preventing the take-up roller from rotating back. This ensures the winding quality and solves the problem that the existing foam pearl cotton board winding device lacks a limiting anti-rotation structure for the take-up roller. If the pearl cotton board is dragged during winding, it will cause the take-up roller to rotate back, affecting the winding quality.

[0008] Preferably, the rotating assembly includes a connector, a rocker arm, and a sheath; the right end of the first drive shaft is fitted with a connector through the mounting frame, a rocker arm is fixed to the connector, and a sheath is fitted on the outer side of the rocker arm.

[0009] Preferably, the linkage assembly includes a first gear, a second gear, a third gear, and a fourth gear; the first gear is mounted on the outer side of the first drive shaft, the second gear is mounted on the second drive shaft, the first gear meshes with the second gear, the third gear is also mounted on the second drive shaft, and the fourth gear is mounted on the left end of the take-up roller, the third gear meshes with the fourth gear.

[0010] Preferably, the positioning component includes a rotating rod, a handle, and a brake pad; the rotating rod is rotatably connected to the inside left side of the mounting frame, a handle is provided at the rear end of the rotating rod, the brake pad is wrapped around the outside of the turntable, and the two ends of the brake pad are fixed to the rotating rod.

[0011] Preferably, the limiting mechanism includes an elastic component and a pressing component. The elastic component is used to drive the pressing component to press tightly against the pearl cotton board, and the pressing component is used to position the pearl cotton board.

[0012] Preferably, the elastic component includes a mounting base, a guide rod, a spring, and a slider; the mounting base is provided on the inner left side of the mounting frame, the guide rod is installed inside the mounting base, the spring is sleeved on the outer side of the guide rod, the front end of the spring is fixedly connected to the mounting base, the rear end of the spring is fixedly connected to the slider, and the slider is slidably connected to the guide rod.

[0013] Preferably, the clamping assembly includes a mounting rod and a sleeve; the mounting rod is fixed to the left end of the slider, and the sleeve is rotatably connected to the outside of the mounting rod.

[0014] The beneficial effects of this utility model are: By employing a combination of limiting claws and ratchet gears, the winding roller can be effectively prevented from rotating unexpectedly during operation, thus ensuring that the EPE foam board maintains a stable tension state throughout the winding process. This design significantly improves winding quality and avoids problems such as interlayer misalignment and surface wrinkles caused by material looseness. At the same time, the stable winding state also reduces material loss in subsequent processing, improves production efficiency, and provides a reliable guarantee for the large-scale production of EPE foam products.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5This utility model provides an embodiment of a foam pearl cotton board winding device, including a mounting frame 1; it also includes a ratchet 11, a first drive shaft 2 rotatably connected to the front inside of the mounting frame 1, a second drive shaft 3 rotatably connected to the rear inside of the mounting frame 1, a winding roller 4 rotatably connected to the lower inside of the mounting frame 1, a rotating component provided on the left side of the mounting frame 1 corresponding to the position of the first drive shaft 2, the rotating component being used to drive the first drive shaft 2 to rotate, a linkage component provided on the three drive shafts, a fixing rod 7 fixed to the upper inside of the mounting frame 1, a connecting rod 8 fixed to the outer side of the fixing rod 7, the connecting rod 8 being rotatably connected to the first drive shaft 2, a limit pawl 9 installed on the right end of the outer side of the fixing rod 7, and the second drive shaft... A turntable 10 is installed on the outer right end of the 3, and a ratchet 11 is connected to the turntable 10. The limiting pawl 9 engages with the ratchet 11. A limiting mechanism is set on the inner right side of the mounting frame 1, and a positioning component is set on the outer side of the turntable 10. The first transmission shaft 2 is driven to rotate by the rotation component. Under the action of the linkage component, the second transmission shaft 3 and the take-up roller 4 rotate synchronously. When the second transmission shaft 3 is running, it will drive the turntable 10 and the ratchet 11 to rotate synchronously. During this process, the tooth groove of the ratchet 11 will engage with the limiting pawl 9 in sequence, thereby effectively limiting the reverse rotation of the ratchet 11. This mechanical interlocking mechanism can reliably prevent the take-up roller 4 from rotating, and ultimately ensure the quality stability of the take-up operation.

[0019] Please see Figures 2-4In this embodiment, the rotating assembly includes a connector 51, a rocker arm 52, and a sheath 53. The right end of the first drive shaft 2 is connected to the mounting frame 1 via the connector 51. A rocker arm 52 is fixed to the connector 51, and a sheath 53 is fitted over the outer side of the rocker arm 52. By connecting the connector 51 and the rocker arm 52, the second drive shaft 3 can be rotated when the rocker arm 52 is rotated. The linkage assembly includes a first gear 61, a second gear 62, a third gear 63, and a fourth gear 64. The first gear 61 is mounted on the outer side of the first drive shaft 2, and the second gear 62 is mounted on the second drive shaft 3. The first gear 61 meshes with the second gear 62. The third gear 63 is also mounted on the second drive shaft 3. The left end of the take-up roller 4 is equipped with a fourth gear 64, and the third gear 63 meshes with the fourth gear 64. Multiple gears are provided. When the first drive shaft 2 rotates, the first gear 61 meshes with the second gear 62 to drive the second drive shaft 3 to rotate. When the second drive shaft 3 rotates, the third gear 63 meshes with the fourth gear 64 to drive the take-up roller 4 to rotate. The positioning component includes a rotating rod 121, a handle 122, and a brake pad 123. The rotating rod 121 is rotatably connected to the inner left side of the mounting frame 1. The handle 122 is provided at the rear end of the rotating rod 121. The brake pad 123 is wrapped around the outside of the turntable 10. The two ends of the brake pad 123 are fixed to the rotating rod 121. By setting the rotating rod 121, when the rotating rod 121 is pressed down, the rotating rod 121 rotates around the hinge point, so that the brake pad 123 tightly wraps around the outside of the turntable 10, thereby preventing the turntable 10 from rotating and achieving the function of braking.

[0020] Please see Figure 1 and Figure 5 In this embodiment, the limiting mechanism includes an elastic component and a pressing component. The elastic component is used to drive the pressing component to press tightly against the pearl cotton board, and the pressing component is used to position the pearl cotton board. The elastic component includes a mounting base 131, a guide rod 132, a spring 133, and a slider 134. The mounting base 131 is provided on the left side inside the mounting frame 1. The guide rod 132 is installed inside the mounting base 131. The spring 133 is sleeved on the outside of the guide rod 132. The front end of the spring 133 is fixedly connected to the mounting base 131, and the rear end of the spring 133 is fixedly connected to the slider 134. The slider 134 and the guide rod 132 are connected. The sliding connection is achieved by setting a guide rod 132. The slider 134 slides along the guide rod 132 under the extension and retraction of the spring 133. The clamping assembly includes a mounting rod 135 and a sleeve 136. The mounting rod 135 is fixed to the left end of the slider 134, and the sleeve 136 is rotatably connected to the outside of the mounting rod 135. By setting the mounting rod 135 and the sleeve 136, the sleeve 136 is always in contact with the pearl cotton board during winding. At this time, the slider 134 will compress the spring 133 to contract, and the elastic restoring force of the spring 133 will act back on the slider 134, thereby making the sleeve 136 tightly in contact with the pearl cotton board.

[0021] During operation, the operator rotates the rocker arm 52, which drives the first drive shaft 2 to rotate via the connector 51. The first gear 61 mounted on the first drive shaft 2 drives the second gear 62, which meshes with it, to rotate, thereby driving the second drive shaft 3 to rotate. The third gear 63 on the second drive shaft 3 drives the fourth gear 64, which meshes with it, to rotate, causing the take-up roller 4 to rotate for winding operations. Simultaneously, the rotation of the second drive shaft 3 drives the turntable 10 and ratchet 11 on its outer side to rotate synchronously. When the ratchet 11 rotates, the limiting claws 9 fixed on the outer side of the fixing rod 7 will sequentially engage in the tooth grooves of the ratchet 11, preventing the ratchet 11 from rotating in the opposite direction. This prevents the take-up roller 4 from rotating due to the dragging of the pearl cotton board, thus affecting the take-up quality. When it is necessary to forcibly stop or fix the position of the take-up roller 4, press down the handle 122 to drive the rotating rod 121 to rotate, so that the brake pads 123 fixed at both ends of the rotating rod 121 tightly wrap around the outer side of the turntable 10, achieving a stop. During the take-up process, the sleeve 136, under the push of the pearl cotton board, drives the slider 134 to slide backward along the guide rod 132 through the mounting rod 135 and compress the spring 133. The elastic restoring force of the spring 133, in turn, pushes the slider 134 and the mounting rod 135, so that the sleeve 136 is always tightly pressed against the pearl cotton board, playing a positioning role.

[0022] Through the above steps, a rotating component is used as the power source. The rotational motion is transmitted to the linkage component through the first transmission shaft 2. The linkage component synchronously distributes the power to the second transmission shaft 3 and the take-up roller 4, so that the two maintain the same speed. During the operation of the second transmission shaft 3, the turntable 10 installed at its end drives the ratchet 11 to rotate synchronously. When rotating, the toothed structure of the ratchet 11 will engage with the fixed-position limiting pawl 9 in sequence to form a one-way locking mechanism. This design effectively prevents the ratchet 11 and the second transmission shaft 3 connected to it from rotating in the opposite direction, thereby completely eliminating the possibility of the take-up roller 4 rotating back, ensuring the stability of the winding process and the quality of the finished product. This solves the problem that the existing foam pearl cotton board winding device lacks a limiting anti-rotation structure for the take-up roller 4 during use. If the pearl cotton board is dragged during winding, it will drive the take-up roller 4 to rotate back, affecting the winding quality.
