Description

Technical Field

[0001] The present invention relates to the field of sponge processing, and particularly to a sponge reel structure. Background Art

[0002] In the field of sponge processing, it is usually necessary to wind the formed sponge through a reel for convenient later transportation.

[0003] Specifically, for a sponge reel structure with the patent number CN219489238U, the device has the following defects when in use. For example, it can only fix and press the end of the sponge, and cannot shape the wound sponge. Even if both ends of the sponge are fixed, the sponge is still prone to being in a loose state. Moreover, components such as its pressing plate and adjusting rod are located outside the limiting plate, resulting in the need for people to lift the wound sponge to move it, and it cannot drive the reel to move on the ground by rolling the limiting disk, leading to difficult displacement. Summary of the Invention

[0004] The purpose of the present invention is to provide a sponge reel structure.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] A sponge reel structure includes two groups of circular limiting plates and a reel connecting the two groups of limiting plates:

[0007] A shaping mechanism is arranged on the inner side wall of the limiting plate. There is a locking mechanism I between the two groups of shaping mechanisms, and there is also a locking mechanism II between the locking mechanism I and the reel;

[0008] The shaping mechanism includes a circular strip-shaped groove arranged around the edge of the inner side wall of the limiting plate. A limiting ring is arranged in the strip-shaped groove, and a screw rod passing through the side wall of the limiting plate is fixed on the limiting ring through a bearing;

[0009] The locking mechanism I includes a U-shaped plate located between the two groups of limiting rings. The U-shaped plate can be fixed on the corresponding limiting ring through bolts. Cross bars are arranged on both the upper and lower sides of the U-shaped plate. The upper and lower cross bars are connected by a vertical rod passing through the U-shaped plate, and a spring I is sleeved on the vertical rod between the lower cross bar and the U-shaped plate;

[0010] The locking mechanism II includes a sliding groove arranged on the inner side wall of the limiting plate. A pressing rod is arranged between the two groups of sliding grooves, and a sliding rod passing through the pressing rod is vertically arranged in the sliding groove. A spring II is sleeved on the sliding rod above the pressing rod.

[0011] Preferably, the bottom surfaces of the pressing rod and the lower cross bar are uniformly provided with rubber protrusions in a conical structure.

[0012] Preferably, the length of the cross bar is less than the length of the C-shaped plate, and the length of the C-shaped plate is less than the distance between the two groups of limiting plates. A through hole for the vertical bar to pass through is provided on the side wall of the horizontal end of the C-shaped plate.

[0013] Preferably, sliding holes for the sliding rods to pass through are provided at both ends of the pressing rod.

[0014] Preferably, a threaded hole for the screw rod to pass through is provided on the side wall of the strip-shaped groove, and the screw rod is screwed and fixed with the threaded hole.

[0015] The beneficial effects of the present invention are as follows: when the limiting ring in the shaping mechanism slides out of the strip-shaped groove and is sleeved on the sponge roll at the same time, the two ends of the sponge roll are shaped, preventing it from bursting and being in a loose state. And through the locking mechanism I and the locking mechanism II, the two ends of the sponge roll are locked and fixed, which is convenient for its winding and can also prevent it from loosening. At the same time, since the locking mechanism I, the locking mechanism II and the shaping mechanism are all located inside the two groups of limiting plates, it will not affect the problem that the limiting plates roll on the ground and drive the sponge roll to move.

Detailed Embodiments

[0020] Next, through embodiments and in combination with the attached Figure 1-3 , the technical solutions of the present invention will be further specifically described.

[0021] A sponge winding drum structure includes two circular limiting plates 1 and a winding drum 2 connecting the two groups of limiting plates 1:

[0022] A shaping mechanism 3 is provided on the inner side wall of the limiting plate 1. A locking mechanism I 4 is provided between the two groups of shaping mechanisms 3, and a locking mechanism II 5 is further provided between the locking mechanism I 4 and the winding drum 2;

[0023] The shaping mechanism 3 includes a circular strip-shaped groove 31 provided around the edge of the inner side wall of the limit plate 1. A limit ring 32 is arranged in the strip-shaped groove 31, and a screw rod 34 passing through the side wall of the limit plate 1 is fixed on the limit ring 32 through a bearing 33. A screw hole for the screw rod 34 to pass through is provided on the side wall of the strip-shaped groove 31, and the screw rod 34 is screwed and fixed with the screw hole.

[0024] The locking mechanism I4 includes a U-shaped plate 41 located between two limit rings 32. The U-shaped plate 41 can be fixed on the corresponding limit ring 32 through a bolt 42. Cross bars 43 are arranged on both the upper and lower sides of the U-shaped plate 41. The upper and lower groups of cross bars 43 are connected by a vertical rod 44 passing through the U-shaped plate 41, and a spring I45 is sleeved on the vertical rod 44 between the lower cross bar 43 and the U-shaped plate 41.

[0025] The locking mechanism II5 includes a sliding groove 51 provided on the inner side wall of the limit plate 1. A pressing rod 52 is arranged between two sliding grooves 51, and a sliding rod 53 vertically arranged in the sliding groove 51 passes through the pressing rod 52. Sliding holes for the sliding rod 53 to pass through are arranged at both ends of the pressing rod 52, and a spring II54 is sleeved on the sliding rod 53 above the pressing rod 52.

[0026] In this embodiment, rubber protrusions 6 with a conical structure are uniformly arranged on the bottom end surfaces of the pressing rod 52 and the lower cross bar 43. When the pressing rod 52 and the cross bar 43 are pressed against the corresponding ends of the sponge, the protrusions 6 facilitate increasing the friction force between it and the sponge end surface to prevent the sponge from slipping or sliding, thereby enhancing the locking and fixing effect on the sponge.

[0027] As Figure 1 、 2 、shown in 3, the length of the cross bar 43 is less than the length of the U-shaped plate 41, and the length of the U-shaped plate 41 is less than the distance between two limit plates 1. A through hole for the vertical rod 44 to pass through is provided on the side wall of the horizontal end of the U-shaped plate 41.

[0028] When the present invention is in use, when pulling the pressing rod 52 upward to drive the sliding hole to slide upward on the sliding rod 53 while compressing the spring II54, at this time, place the end of the sponge between the winding drum 2 and the pressing rod 52. Then, when releasing the spring II54, under the influence of its driving force, the pressing rod 52 presses and fixes the end of the sponge, so as to facilitate the rotation of components such as the winding drum 2 to realize the winding work of the sponge.

[0029] After the winding is completed, the total diameter of the sponge roll matches the inner diameter of the limiting ring 32, or is slightly larger than the inner diameter of the limiting ring 32. Then, the sponge roll can be slightly squeezed to deform its end, so that the limiting ring 32 can be easily sleeved on the end of the sponge roll. The specific operation is to rotate the screw 34 in the screw hole and on the bearing 33 to push the limiting ring 32 to slide out of the strip groove 31 and sleeve on the sponge roll, thereby shaping the two ends of the sponge roll to prevent it from collapsing and being in a loose state. Then, the locking mechanism is tightened. I4 is placed between the two groups of limit rings 32, and the shaping plate 41 is locked and fixed on the corresponding limit ring 32 by bolts 42. At the same time, the upper cross bar 43 is loosened. Then, the lower cross bar 43 will be pressed against the end of the outer side of the sponge roll by the expansion force of the spring I45 to lock and fix the end. In the above process, the locking mechanism I4, the locking mechanism II5 and the shaping mechanism 3 are all located on the inner side of the two groups of limit plates 1, so that they will not affect the problem of the limit plate 1 rolling on the ground and driving the sponge roll to move.

[0030] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
