Description

Technical Field

[0001] The utility model belongs to the field of winding and unwinding equipment, and particularly relates to a sponge reel winding and unwinding rack. Background Art

[0002] In the process of combined production of sponge and leather goods, both the sponge and the leather goods are wound up after the previous production process and then transported to the next process for combined operation. Therefore, both the sponge and the leather goods are stored and transported in the workshop in the form of reels. However, in the production of the previous process, the newly produced sponge often has the layers in contact with each other sticking together. After entering the next process, when the sponge is unwound and the discharging surface is fed into the production equipment, under the action of the pulling force, the split roll material is gradually unwound. Due to inertia and the viscosity between the sponges, after the front-end equipment pauses, the split roll material rotates excessively in the rotating direction, causing the discharging surface to be driven in the reverse direction. After the front-end equipment runs again, the overly driven discharging surface will be too stretched and fall to the ground and rub against the ground, which will pollute the sponge in the lightest case and cause wear in the worst case. Moreover, the excessive viscosity between the sponges will also lead to unsmooth discharging during normal production. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a sponge reel winding and unwinding rack. By starting the air cylinder, the lifting of the split roll material on the support seat is realized. The supporting shaft on the support seat abuts against the outer side surface and the discharging surface of the split roll material, and the sponge on the split roll material can be separated by the weight of the supporting shaft, avoiding the pollution of the sponge and unsmooth discharging in subsequent production.

[0004] To achieve the above object, the technical scheme adopted by the utility model is as follows:

[0005] A sponge reel winding and unwinding rack includes a frame, a supporting component and a split roll component. The frame is enclosed by a front frame and two groups of side frames. The supporting component includes an air cylinder, a guide rail and a support seat. The air cylinder is connected to the side frame, the guide rail is arranged on the side frame at the lower end of the air cylinder, the support seat is movably connected to the guide rail, and the output end of the air cylinder is connected to the support seat. There are two groups of the supporting components, and the two groups of the supporting components are symmetrically arranged on the two groups of side frames respectively; the split roll component includes a connecting shaft, a split roll material, an extension plate, a supporting rod and a supporting shaft. The connecting shaft passes through the cylinder in the center of the split roll material shaft, and the left and right ends of the connecting shaft are respectively embedded in the grooves on the two groups of support seats. The extension plate is provided with a guide post, and the guide post is matched with the guide hole on the support seat. One end of the supporting rod is rotatably connected to the extension plate, the bottom of the supporting rod can abut against and be connected to the guide post, the other end of the supporting rod is rotatably connected with a supporting shaft, the axis of the supporting shaft is parallel to the axis of the split roll material, and the supporting shaft abuts against the outer side surface and the discharging surface of the split roll material.

[0006] The material supporting shaft is provided with a material distributing wheel group. The material distributing wheel group is composed of a support frame and two groups of rollers. The support frame is fixed on the material supporting shaft, and the two groups of rollers are rotatably connected to the support frame. The material supporting shaft and the two groups of rollers form a triangular structure on the lower side. One group of rollers abuts against the outer side of the split coil material, and the other group of rollers abuts against the discharging surface of the split coil material; the two groups of rollers abut against each other.

[0007] For the sponge reel winding and unwinding rack adopting this structure, the frame plays the most basic supporting role. The frame is enclosed by a front frame and two groups of side frames. The front frame is provided with a transmission cylinder for sending out the discharging surface of the split coil material, and on the two groups of side frames, there are support components. Through the cylinders on the side frames, the support seats movably connected to the guide rails are pulled to move up and down. The connecting shaft passing through the upper material cylinder of the split coil material has its two ends embedded in the grooves on the two support seats. Therefore, when the cylinders are started, the split coil material can be lifted up and down, and the split coil material can rotate with the connecting shaft as the rotation center, and during the rotation process, the material is discharged. The discharged discharging surface abuts against the transmission cylinder and is sent to the next production process.

[0008] In order to smoothly send out the discharging surface sent out by the split coil material and prevent the split coil material from sticking due to the stickiness of the sponge, an extension plate, a material supporting rod and a material supporting shaft are added. The guiding columns on the extension plate are restricted in the guiding holes on the supporting plate. Therefore, the extension plate can be horizontally moved in the form of manual pushing, so that the extension plate is moved to abut against the support seat for storage in the non-working state. When in need of use, the extension plate is pushed close to the split coil material without contacting the split coil material. The material supporting rod rotatably connected to the extension plate is rotated to the connection position between the split coil material and the discharging surface, and the material supporting shaft on the material supporting rod is placed at the connection position between the split coil material and the discharging surface. Relying on the weight of the material supporting shaft, the discharging surface is pressed downward to open, so that the discharging surface will not stick to the split coil material again. In order to prevent the material supporting shaft from sinking excessively, the bottom of the material supporting rod abuts against the guiding column, which can prevent the material supporting shaft from rotating downward excessively. Therefore, even if the front-end equipment pauses later, the discharging surface will not rotate in the reverse direction due to stickiness.

[0009] However, even with the material supporting shaft, it is impossible to avoid that under the inertia of stretching, the split coil material will rotate excessively after the front-end equipment pauses, resulting in the discharging surface being driven in the reverse direction. Therefore, a material distributing wheel group is added. The material distributing wheel group is fixed with the material supporting shaft as the rotation center. The two groups of rollers on the support frame respectively abut against the outer side of the split coil material and the discharging surface of the split coil material. At the same time, the two groups of rollers abut against each other. Therefore, when the discharging surface is fed upward, the two groups of rollers are driven in sequence and then abut against the outer side of the split coil material. When the discharging surface stops, the two groups of rollers will also stop, thus forcing the split coil material to stop at the same time, thereby avoiding the discharging surface being driven in the reverse direction after the front-end equipment pauses.

[0010] Further, the volume-dividing component further includes a metering rod and a metering wheel. The metering rod is rotatably connected to the extension plate, and the other end of the metering rod is rotatably connected with a metering wheel. The metering wheel can be abutted against the outer side surface of the volume-dividing material. A clamping groove is further provided on the extension plate, and the metering rod can be abutted and connected in the clamping groove.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: Through the arrangement of the material-supporting shaft, the discharging surface is pressed downward by its own weight, so that the discharging surface will not adhere to the volume-dividing material, avoiding the reverse rotation of the discharging surface due to viscosity when the front-end equipment pauses. The provided material-dividing wheel set has two groups of rollers abutted against each other. When the discharging surface stops, the two groups of rollers will also stop, thereby forcing the volume-dividing material to stop at the same time, thus avoiding the reverse driving of the discharging surface after the front-end equipment pauses, and avoiding the soiling caused by the discharging surface being dragged on the ground after being taken away too much, and also improving the discharging smoothness of the discharging surface.

[0020] The following will describe the detailed implementation manners of the present utility model in conjunction with the drawings:

[0021] As Figures 1-5 shown, a sponge roll winding and unwinding rack includes a frame 1, a support assembly 2 and an unrolling and rewinding assembly 3. The frame 1 is enclosed by a front frame 11 and two groups of side frames 12. The support assembly 2 includes a cylinder 21, a guide rail 22 and a support seat 23. The cylinder 21 is connected to the side frame 12. The guide rail 22 is arranged on the side frame 12 at the lower end of the cylinder 21. The support seat 23 is movably connected to the guide rail 22. The output end of the cylinder 21 is connected to the support seat 23. The support assembly 2 includes two groups, and the two groups of support assemblies 2 are symmetrically arranged on the two groups of side frames 12 respectively. The unrolling and rewinding assembly 3 includes a connecting shaft 31, an unrolling material 32, an extension plate 33, a material supporting rod 34 and a material supporting shaft 35. The connecting shaft 31 passes through the material cylinder 321 at the axis center of the unrolling material 32. The left and right ends of the connecting shaft 31 are respectively embedded in the grooves 231 on the two groups of support seats 23. The extension plate 33 is provided with guide posts 331, and the guide posts 331 cooperate with the guide holes 232 on the support seat 23. One end of the material supporting rod 34 is rotatably connected to the extension plate 33, the bottom of the material supporting rod 34 can abut and be connected to the guide posts 331, the other end of the material supporting rod 34 is rotatably connected with a material supporting shaft 35, the axis center of the material supporting shaft 35 is parallel to the axis center of the unrolling material 32, and the material supporting shaft 35 abuts on the outer side surface and the discharging surface 322 of the unrolling material 32.

[0022] A material supporting shaft 35 is provided with a material distributing wheel set 36. The material distributing wheel set 36 is composed of a support frame 361 and two groups of rollers 362. The support frame 361 is fixed on the material supporting shaft 35. The two groups of rollers 362 are rotatably connected to the support frame 361. The material supporting shaft 35 and the two groups of rollers 362 form a triangular structure on the lower side. One group of rollers 362 abuts against the outer side surface of the split coil 32, and the other group of rollers 362 abuts against the discharging surface 322 of the split coil 32; the two groups of rollers 362 abut against each other.

[0023] Further, the split coil assembly 3 further includes a measuring rod 37 and a measuring wheel 38. The measuring rod 37 is rotatably connected to the extension plate 33. The other end of the measuring rod 37 is rotatably connected with a measuring wheel 38. The measuring wheel 38 can abut against the outer side surface of the split coil 32. A clamping groove 332 is further provided on the extension plate 33. The measuring rod 37 can abut against and be connected in the clamping groove 332.

[0024] The working mode of the present utility model is described as follows:

[0025] For the sponge reel winding and unwinding rack with this structure, the frame 1 plays the most basic supporting role. The frame 1 is formed by enclosing a front frame 11 and two groups of side frames 12. The front frame 11 is provided with a transmission cylinder for the discharging surface 322 of the split coil 32 to be sent out. And on the two groups of side frames 12, a supporting assembly 2 is provided. Through the air cylinder 21 on the side frame 12, the support seat 23 that is movably connected to the guide rail 22 is pulled to move up and down. And for the connecting shaft 31 passing through the loading cylinder 321 of the split coil 32, its two ends are embedded in the grooves 231 on the two groups of support seats 23. Therefore, when the air cylinder 21 is started, the split coil 32 can be lifted up and down. And the split coil 32 can rotate with the connecting shaft 31 as the rotation center, and during the rotation, the material is discharged. The discharged discharging surface 322 is abutted against the transmission cylinder and sent to the next production process.

[0026] In order to smoothly send out the discharging surface 322 sent out by the split coil material 32 without sticking the split coil material 32 due to the stickiness of the sponge, an extension plate 33, a material supporting rod 34 and a material supporting shaft 35 are added. The guide post 331 on the extension plate 33 is restricted in the guide hole 232 on the support plate. Therefore, the extension plate 33 can be horizontally moved by manual pushing, so that the extension plate 33 is moved to abut against the support seat 23 for storage in the non-working state. When in need of use, the extension plate 33 is pushed to be close to the split coil material 32 without contacting the split coil material 32. The material supporting rod 34 rotatably connected to the extension plate 33 is rotated to the connection part between the split coil material 32 and the discharging surface 322, and the material supporting shaft 35 on the material supporting rod 34 is placed at the connection part between the split coil material 32 and the discharging surface 322. The discharging surface 322 is pressed downward by relying on the weight of the material supporting shaft 35, so that the discharging surface 322 will not stick to the split coil material 32. In order to prevent the material supporting shaft 35 from sinking excessively, the bottom of the material supporting rod 34 is abutted against the guide post 331, which can prevent the material supporting shaft 35 from rotating downward excessively. Therefore, even if the front-end equipment pauses later, the discharging surface 322 will not rotate reversely due to stickiness.

[0027] However, even with the material supporting shaft 35, it is impossible to avoid the split coil material 32 from rotating excessively after the front-end equipment pauses under the inertia of stretching, resulting in the discharging surface 322 being driven reversely. Therefore, a material dividing wheel set 36 is added. The material dividing wheel set 36 is fixed with the material supporting shaft 35 as the rotation center. The two groups of rollers 362 on the support frame 361 respectively abut against the outer side surface of the split coil material 32 and the discharging surface 322 of the split coil material 32. At the same time, the two groups of rollers 362 abut against each other. Therefore, when the discharging surface 322 feeds upward, the two groups of rollers 362 are driven in sequence and then abut against the outer side surface of the split coil material 32. When the discharging surface 322 stops, the two groups of rollers 362 will also stop, thereby forcing the split coil material 32 to stop simultaneously, thus avoiding the discharging surface 322 being driven reversely after the front-end equipment pauses.

[0028] At the same time, a measuring rod 37 and a measuring wheel 38 are provided on the extension plate 33. The measuring wheel 38 can be rotated to abut against the material cylinder 321. When the split coil material 32 is fed, the material cylinder 321 will also rotate. Since the length of each split coil is basically the same, the number of rotation turns of the material cylinder 321 will also be fixed. Therefore, the length size of each material discharge can be obtained through the measuring wheel 38. When measurement is not required, the measuring rod 37 can be rotated and retracted into the clamping groove 332.

[0029] The beneficial effects of the present utility model are as follows: Through the setting of the material supporting shaft 35, the discharging surface 322 is pressed downward by relying on its own weight, so that the discharging surface 322 will not adhere to the unrolling material 32. When the front-end equipment pauses, it can avoid the reverse rotation of the discharging surface 322 due to viscosity. The provided material distributing wheel set 36 has two groups of rollers 362 abutted against each other. When the discharging surface 322 stops, the two groups of rollers 362 will also stop, thereby forcing the unrolling material 32 to stop at the same time. Thus, it avoids the reverse driving of the discharging surface 322 caused after the front-end equipment pauses, and also avoids the pollution and damage caused by dragging the discharging surface 322 on the ground after the discharging surface 322 is driven away too much. It also improves the discharging smoothness of the discharging surface 322.

[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
