Description

Technical Field

[0001] The utility model belongs to the technical field of tarpaulin production and relates to unwinding and supporting equipment for a tarpaulin roll. Background Art

[0002] Tarpaulin (also known as waterproof fabric) is a strong, flexible, and waterproof material. It's commonly made of canvas, polyurethane-coated polyester, or polyethylene plastic. Tarpaulins typically have sturdy grommets at the corners or edges for easy tying, hanging, or covering.

[0003] During the initial production phase, the tarpaulin is wound around a roll. The roll is then placed on a support frame, and workers manually pull the free end of the tarpaulin until the desired length of tarpaulin fits onto the support platform. The support platform is porous and has an exhaust structure underneath, which keeps the tarpaulin in place under negative pressure. The three-axis frame then moves, and a cutter is used to cut the tarpaulin into shape. The tarpaulin is wound around a support roller, which is supported by a support frame. Due to the varying widths of different tarpaulins and to prevent edge damage, the support frame is typically wider than the width of the tarpaulin, enabling the support frame to stably support tarpaulin rolls of varying sizes. However, in practice, it has been found that when workers manually pull the tarpaulin roll, the pulling forces applied to the tarpaulin roll by both sides can deviate or become asymmetric. This often causes relative movement between the support roller and the support frame, shifting the position of the tarpaulin roll. This can easily cause wrinkles in the tarpaulin after it is pulled onto the support platform, resulting in a cut shape that differs from the desired shape and poor production results.

DETAILED DESCRIPTION

[0026] The following is a detailed description of the tarpaulin roll unwinding and support device proposed in the present invention, combined with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clarify the description of the embodiments of the present invention. Identical or similar reference numerals in the drawings represent identical or similar components.

[0027] A tarpaulin roll unwinding support device, such as Figures 1 to 8 As shown, it includes two relatively arranged support frames 1, the top of the support frame 1 is provided with a support groove 2, the two support grooves 2 are used to support a tarpaulin roll 3, and a limit plate 4 is horizontally arranged on the outer side of the support frame 1. The limit plate 4 is movably buckled with a limit ring 5, and the inner wall of the limit ring 5 is movably fitted to the limit plate 4. A limit part 6 is vertically provided on the top of the limit plate 4, and the two limit parts 6 are respectively fitted to the two ends of the tarpaulin roll 3, and a fixing unit for fixing the position of the limit ring 5 is provided on the limit plate 4.

[0028] The top of the limiting plate 4 is provided with a long limiting groove 7, the length direction of the limiting groove 7 is in the same direction as the length direction of the limiting plate 4, the inner wall of the limiting ring 5 is provided with a synchronization bar 8 that is movably attached to the inner wall of the limiting groove 7, and the fixing unit includes a plurality of fixing blocks 9 that are sequentially attached;

[0029] When fixing the position of the tarpaulin reel 3, there are several fixing blocks 9 between the outer end of the synchronization bar 8 and the outer end of the limiting groove 7. Both sides of the fixing block 9 are in contact with the inner walls of the limiting groove 7. The outer side of the fixing block 9 at the outer end is in contact with the inner wall of the outer end of the limiting groove 7, and the inner side of the fixing block 9 at the inner end is in contact with the synchronization bar 8.

[0030] A linkage portion 10 is provided on the side of the limiting ring 5 , and a first elastic member 11 that is continuously in an extended state is provided between the linkage portion 10 and the outer side of the support frame 1 .

[0031] A positioning strip 12 made of elastic material is provided on the side of the limiting ring 5 facing away from the support frame 1, and a positioning portion 13 perpendicular to the positioning strip 12 is provided on the lower side of the positioning strip 12. When the inner side of the positioning portion 13 abuts against the outer end of the limiting plate 4, the length of the first elastic member 11 is at its maximum state, and the outer end of the synchronization bar 8 abuts against the inner wall of the outer end of the limiting groove 7.

[0032] A guide cylinder 14 is vertically provided on the top of the limiting plate 4, and a termination plate 15 is horizontally provided on the inner wall of the guide cylinder 14. The termination plate 15 is higher than the limiting plate 4. A plurality of first stabilizing grooves 16 are vertically opened on the inner wall of the guide cylinder 14 below the termination plate 15. A second stabilizing groove 17 cooperating with the first stabilizing groove 16 is opened on the inner wall of the limiting groove 7. Stabilizing bars 18 are vertically provided on both sides of the fixing block 9. The stabilizing bars 18 can be movably located in the first stabilizing groove 16 or the second stabilizing groove 17. When the top of the fixing block 9 contacts the termination plate 15, the bottom of the fixing block 9 is higher than the synchronization bar 8.

[0033] A reset magnet 19 is further included. The reset magnet 19 can be magnetically attracted to the fixing blocks 9 . When the reset magnet 19 is attached to the termination plate 15 , all the fixing blocks 9 are in contact with the termination plate 15 .

[0034] The side walls of the reset magnet 19 are movably fitted to the inner wall of the guide cylinder 14, and an inverted U-shaped movable frame 20 is provided on the top of the guide cylinder 14. Two guide rods 21 are vertically provided on the top of the reset magnet 19, and the two guide rods 21 are movable through the top of the movable frame 20, and the outer walls of the guide rods 21 are movably fitted to the movable frame 20. A second elastic member 22 that is continuously in an extended state is provided between the top of the reset magnet 19 and the lower side of the top of the movable frame 20, and an anti-slip plate 23 for limiting the reset magnet 19 is horizontally provided on the top of the guide cylinder 14. When the top of the reset magnet 19 contacts the anti-slip plate 23, the magnetic attraction force applied by the reset magnet 19 to the fixed block 9 is less than the gravity of the fixed block 9.

[0035] A pressing rod 24 is vertically provided in the middle of the top of the reset magnet 19 , and a pressing plate 25 is horizontally provided on the top of the pressing rod 24 . The pressing rod 24 movably passes through the middle of the movable frame 20 .

[0036] A hemispherical auxiliary portion 26 is provided inside the limiting portion 6 . The tarpaulin reel 3 is hollow, and the auxiliary portion 26 is engaged with the end of the tarpaulin reel 3 .

[0037] A plurality of rotating rollers 27 are rotatably provided on the inner wall of the support groove 2 , and the outer wall of the tarpaulin reel 3 movably contacts the rotating rollers 27 .

[0038] The unwinding support device for the tarpaulin roll provided by the present invention, when in use, firstly, the tarpaulin roll 3 wrapped with the tarpaulin roll (not the object to be protected by this application, and is only introduced for auxiliary explanation) is horizontally placed in the two supporting grooves 2, and then the two limiting rings 5 are moved along the length direction of the limiting plate 4, and the movement of the limiting rings 5 is stopped after the limiting portion 6 is attached to the outer end of the tarpaulin roll 3. At this time, the two outer ends of the tarpaulin roll 3 can be limited by the two limiting portions 6. In this way, even if the tarpaulin roll 3 has a tendency to shift in position during the subsequent manual pulling of the tarpaulin by the worker, since the end of the tarpaulin roll 3 is limited by the limiting portion 6 at this time, the tarpaulin roll 3 can be prevented from shifting in position, thereby ensuring the position stability of the tarpaulin roll, so that the tarpaulin can be better laid on the support platform after being pulled, thereby ensuring the production effect.

[0039] At the same time, the worker releases the lower pressure plate 25, and under the elastic force of the second elastic member 22, the reset magnet 19 is raised until it contacts the lower side of the anti-slip plate 23.

[0040] At this time, since the limiting parts 6 and the auxiliary parts 26 on both sides are separated from the tarpaulin roll 3, the tarpaulin roll 3 can be directly removed; then after placing the new tarpaulin roll 3, the worker only needs to swing the free end of the positioning bar 12 upwards and make the positioning part 13 slightly higher than the top of the limiting plate 4. At this time, under the elastic force of the first elastic member 11, the limiting part 6, the limiting ring 5, and the synchronization bar 8 all move toward the support frame 1 until the limiting parts 6 on both sides contact the two ends of the tarpaulin roll 3. When the synchronization bar 8 moves toward the support frame 1, it can no longer support part of the fixed block 9. In this way, this part of the fixed block 9 moves downward under the action of gravity and falls between the outer ends of the synchronization bar 8 and the limiting groove 7; the fixed blocks 9 are in a state of mutual contact, so even if the tarpaulin reel 3 has an outward force, the fixed block 9 can also withstand the force of the tarpaulin reel 3 well; secondly, the first stabilizing groove 16 and the second stabilizing groove 17 guide the stabilizing bar 18, so that the fixed block 9 can move stably vertically, ensuring the lifting stability of the fixed block 9.

[0041] The auxiliary portion 26 is inserted into the inner wall of the tarpaulin roll 3, which not only limits the ends of the tarpaulin roll 3 but also limits the tarpaulin roll 3 in the direction of movement. At the same time, the outer wall of the tarpaulin roll 3 is supported by rotating rollers 27, making it easier to rotate the tarpaulin roll 3 and reducing the difficulty of manual pulling.

[0042] The above description is only a description of the preferred embodiment of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
