In this process, the alignment and positioning of the tablecloth edge usually depends on the operator's experience and repeated adjustments. It is difficult to quickly find its geometric center and accurately align both ends with one end of the tripod. Repeated adjustments will result in a long folding process and reduce the efficiency of folding processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tripod folding machine for tablecloth production, including a folding machine body, a tripod fixedly installed on one side of the folding machine body, a tablecloth unwinding roller detachably installed on one side of the folding machine body, a first motor fixedly installed on one side of the folding machine body, wherein the output end of the first motor is fixedly installed on one side of the tablecloth unwinding roller by means of a coupling, a plurality of limiting rollers are symmetrically installed through one side of the folding machine body, and a receiving roller is installed through one side of the folding machine body. A second motor is fixedly installed on one side of the main body of the machine. The output end of the second motor is fixedly installed on one side of the collecting roller via a coupling. A limiting device is provided on the inner wall of one end of the folding machine body. When the tablecloth is placed on the grooved roller and laid flat on the tripod, the limiting device rotates the threaded rod according to the width of the tablecloth to drive the two limiting plates to move in opposite directions, thereby limiting and positioning the two sides of the tablecloth so that it can quickly be located in the center of the tripod. The center of the tablecloth is quickly aligned with one end of the tripod, achieving a quick folding effect.

[0006] Preferably, the limiting device includes a grooved roller, with both ends of the grooved roller passing through and installed on both sides of the folding machine body; a threaded rod, with one end of the threaded rod passing through and installed on one side of the inner wall of the grooved roller, wherein the threads at both ends of the threaded rod are in opposite directions; a fixing mechanism, wherein the fixing mechanism is disposed between one end of the threaded rod and one side of the grooved roller, for locking and fixing the rotated threaded rod; two screw hole blocks, wherein the screw hole blocks are slidably installed in the inner wall of the grooved roller, and the inner wall of the screw hole blocks is spirally sleeved on the outer surface of the threaded rod; two limiting plates, wherein the inner wall of the limiting plates is sleeved on the outer surface of the grooved roller, and one side of the inner wall is fixedly installed on one side of the screw hole blocks; and an auxiliary mechanism, wherein the auxiliary mechanism is disposed on one side of the limiting plate, for secondary limiting and fixing of the edge of the tablecloth placed on the grooved roller. The effect achieved by the above components is as follows: By setting a limiting device, when the tablecloth is folded in half using the folding machine body, the tablecloth roll is usually placed on the tablecloth unwinding roller, and then one end is placed between the two limiting plates on the outer surface of the grooved roller. Then it is placed on one side of the tripod. At this time, the threaded rod can be manually rotated according to the width of the tablecloth, so that it drives the two limiting plates and the screw hole block to move in opposite directions on the outer surface and inner wall of the grooved roller, respectively. After moving to a certain position, the auxiliary mechanism can be pulled open, and then the limiting plates can be adjusted until one side of the two limiting plates is aligned. The tablecloth is placed against both ends of the tablecloth. At this point, the auxiliary mechanism is released, and the edges of the tablecloth are pressed and limited on the outer surface of the grooved roller. At the same time, the threaded rod that has rotated to a certain number of turns is limited and fixed by the fixing mechanism. This allows the center of the tablecloth to be quickly aligned with the corner of the tripod, reducing the adjustment time and improving the efficiency of subsequent folding processing. After placing the tablecloth on the tripod, it is folded in half and passed between several limiting rollers, and finally fixed on the storage roller. At this time, the first motor and the second motor can be started at the same time, so that they drive the tablecloth unwinding roller and the storage roller to rotate respectively, and perform unwinding and winding processing of the tablecloth.

[0007] Preferably, a plurality of circular rollers are rotatably mounted on one side of the limiting plate, wherein the plurality of circular rollers are arranged at equal intervals.

A plurality of locking grooves are provided on one side of the threaded rod, wherein one end of the locking rod is inserted into the inner wall of the locking groove.

[0014] The effect achieved by the above components is as follows: by setting a fixing mechanism, after rotating the threaded rod to a certain number of turns, the distance between the two limiting plates is adjusted so that the locking rod can slide to a certain position in the inner wall of one end of the threaded rod under the reset action of the first spring, and then be locked into the corresponding slot to fix and limit the threaded rod. After it is limited, it is not easy for the thread to slip and rotate, thus improving the stability of the limiting and positioning.

[0015] Preferably, the cross-section of the lever is T-shaped.

[0016] The effect achieved by the above-mentioned components is that by setting the lever in a T-shape, it is easy to manually grasp and pull one end during operation.

[0017] Preferably, a circular hole block is rotatably mounted on the outer surface of the clamping rod, and the circular hole block is inserted into the inner wall of one end of the threaded rod.

[0018] The effect achieved by the above-mentioned component is as follows: by setting the round hole block, when the clamping rod is pulled to a certain position in the inner wall of one end of the threaded rod, after one end is pulled out of the groove, the round hole block can be pulled out from the inner wall of the threaded rod. Then the round hole block can be rotated to a certain angle so that one side of it abuts against one side of the threaded rod. This can limit the clamping rod after it is pulled out, which makes it convenient to tighten the threaded rod.

[0019] The beneficial effects of this utility model are: By setting a limiting device, when using the folding machine to fold the tablecloth, the tablecloth roll is usually placed on the tablecloth unwinding roller, and then one end is placed between two limiting plates on the outer surface of the grooved roller. Then it is placed on one side of the tripod. At this time, the threaded rod can be manually rotated according to the width of the tablecloth, so that it drives the two limiting plates and the screw hole block to move in opposite directions on the outer surface and inner wall of the grooved roller, respectively. After moving to a certain position, the auxiliary mechanism can be pulled open, and then the limiting plates can be adjusted until one side of the two limiting plates abuts against the two ends of the tablecloth. This allows the center of the tablecloth to be quickly aligned with the folding corner of the tripod, reducing the adjustment time and improving the efficiency of subsequent folding processing. After placing the tablecloth on the tripod, it is folded in half and passed between several limiting rollers, and finally fixed on the take-up roller. At this time, the first motor and the second motor can be started at the same time, so that they drive the tablecloth unwinding roller and the take-up roller to rotate, respectively, to perform unwinding and take-up processing of the tablecloth.

A limiting device 2 is provided on the inner wall of one end of the folding machine body 1. When the tablecloth is placed on the groove roller 21 and laid flat on the tripod 3, the limiting device 2 rotates the threaded rod 22 according to the width of the tablecloth to drive the two limiting plates 25 to move in opposite directions, limiting and positioning the two sides of the tablecloth so that it can quickly be located in the center of the tripod 3, quickly aligning the center of the tablecloth with one end of the tripod 3, achieving the effect of quick folding.

[0027] Figure 1-4The limiting device 2 shown includes a grooved roller 21, with both ends of the grooved roller 21 passing through and installed on both sides of the folding machine body 1; a threaded rod 22, with one end of the threaded rod 22 passing through and installed on one side of the inner wall of the grooved roller 21, and the threads at both ends of the threaded rod 22 are in opposite directions; a fixing mechanism 23, which is disposed between one end of the threaded rod 22 and one side of the grooved roller 21, for locking and fixing the rotated threaded rod 22; two screw hole blocks 24, which are slidably installed in the inner wall of the grooved roller 21, and the inner wall of the screw hole blocks 24 is spirally sleeved on the outer surface of the threaded rod 22; two limiting plates 25, with the inner wall of the limiting plates 25 sleeved on the outer surface of the grooved roller 21, and one side of the inner wall is fixedly installed on one side of the screw hole blocks 24; and an auxiliary mechanism 27, which is disposed on one side of the limiting plate 25, for secondary limiting and fixing of the edge of the tablecloth placed on the grooved roller 21. By setting the limiting device 2, when using the folding machine body 1 to fold the tablecloth, the tablecloth roll is usually placed on the tablecloth unwinding roller 4, and then one end is placed between the two limiting plates 25 on the outer surface of the grooved roller 21. Then it is placed on one side of the tripod 3. At this time, the threaded rod 22 can be manually rotated according to the width of the tablecloth, so that it drives the two limiting plates 25 and the screw hole block 24 to move in opposite directions on the outer surface and inner wall of the grooved roller 21, respectively. After moving to a certain position, the auxiliary mechanism 27 can be pulled open, and then the limiting plates 25 can be adjusted until one side of the two limiting plates 25 abuts against the ground. The tablecloth is attached to both ends of the tablecloth. The auxiliary mechanism 27 is then released, pressing the edges of the tablecloth against the outer surface of the grooved roller 21. Simultaneously, the threaded rod 22, having rotated a certain number of turns, is fixed by the fixing mechanism 23. This allows the center of the tablecloth to quickly align with the corner of the tripod 3, reducing adjustment time and improving subsequent folding efficiency. After placing the tablecloth on the tripod, it is folded in half and passed between several limiting rollers 6, finally fixed to the collecting roller 7. At this point, the first motor 5 and the second motor 8 can be started simultaneously, driving the tablecloth unwinding roller 4 and the collecting roller 7 to rotate, performing unwinding and rewinding processing on the tablecloth. Several circular rollers 26 are rotatably mounted on one side of the limiting plate 25, arranged at equal intervals. By setting the circular rollers 26, the contact friction between the limiting plate 25 and the tablecloth is reduced, facilitating tablecloth movement.

[0028] Figure 1-4The auxiliary mechanism 27 shown includes a second spring 271, one end of which is fixedly mounted on one side of the limiting plate 25; a circular block 272, the outer surface of which is fixedly mounted on one end of the second spring 271; and a rotating roller 273, one side of which is rotatably mounted on one side of the circular block 272. By setting up the auxiliary mechanism 27, when the two limiting plates 25 block the tablecloth on both sides, the rotating roller 273 and the circular block 272 can be manually pulled upwards to a certain height, causing the second spring 271 to contract. Then, after the edge of the tablecloth abuts against one side of the limiting plate 25, the rotating roller 273 is released. Under the reset action of the second spring 271, the edge of the tablecloth can be pressed and limited, preventing it from shrinking and folding during transport. The auxiliary mechanism 27 also includes a telescopic rod 274, the outer surface of which is installed through the inner wall of the second spring 271, and both ends are fixedly mounted on the outer surface of the circular block 272 and one side of the limiting plate 25, respectively. By setting the telescopic rod 274, the inner wall of the second spring 271 can be supported and reinforced, making it less prone to damage during use, while the up-and-down movement of the round block 272 is more stable.

[0029] Figure 1-4 The fixing mechanism 23 shown includes a locking rod 232, one end of which is inserted into the inner wall of one end of the threaded rod 22; and a first spring 233, the inner wall of which is sleeved on the outer surface of one end of the locking rod 232, with both ends fixedly installed on one side of the locking rod 232 and one side of the threaded rod 22, respectively. A plurality of slots 231 are provided on one side of the threaded rod 22, with one end of the locking rod 232 inserted into the inner wall of the slot 231. By setting the fixing mechanism 23, after rotating the threaded rod 22 a certain number of turns, and adjusting the distance between the two limiting plates 25, the locking rod 232 can slide to a certain position in the inner wall of one end of the threaded rod 22 under the reset action of the first spring 233, and then lock into the corresponding slot 231, fixing and limiting the threaded rod 22. This prevents slippage and rotation, improving the stability of the limiting and positioning.

[0030] Figure 1-4The cross-section of the lever 232 shown is T-shaped. By setting the lever 232 into a T-shape, it is easy to manually grasp and pull one end during operation. A round hole block 234 is rotatably mounted on the outer surface of the lever 232, and the round hole block 234 is inserted into the inner wall of one end of the threaded rod 22. By setting the round hole block 234, when the lever 232 is pulled to a certain position in the inner wall of one end of the threaded rod 22, and one end is pulled out of the slot 231, the round hole block 234 can be pulled out from the inner wall of the threaded rod 22. Then, the round hole block 234 can be rotated to a certain angle so that one side abuts against one side of the threaded rod 22. This limits the lever 232 after it is pulled out, which facilitates the screwing operation of the threaded rod 22.

[0031] Working Principle: When using the folding machine body 1 to fold the tablecloth, the tablecloth roll is usually placed on the tablecloth unwinding roller 4, and one end is placed between the two limiting plates 25 on the outer surface of the grooved roller 21. Then, it is placed on one side of the tripod 3. At this time, depending on the width of the tablecloth, the locking rod 232 is manually pulled to one end in the inner wall of one end of the threaded rod 22 to a certain position. After one end is pulled out of the locking groove 231, the round hole block 234 can be pulled out from the inner wall of the threaded rod 22. Then, the round hole block 234 can be rotated to a certain angle so that one side abuts against one side of the threaded rod 22. This can limit the locking rod 232 after it is pulled out. Then, the threaded rod 22 is manually rotated so that the two limiting plates 25 and the screw hole block 24 move in opposite directions on the outer surface and inner wall of the grooved roller 21, respectively. After moving to a certain position, the rotating roller 273 and the round block 272 can be manually pulled upwards. At a certain height, the second spring 271 is contracted, and the limiting plate 25 is adjusted until one side of the two limiting plates 25 abuts against the edges of both ends of the tablecloth. At this time, the rotating roller 273 is released, and under the reset action of the second spring 271, the edge of the tablecloth can be pressed and limited on the outer surface of the groove roller 21. At the same time, under the reset action of the first spring 233, the locking rod 232 slides to a certain position in the inner wall of one end of the threaded rod 22, and then locks into the corresponding locking groove 231 to fix and limit the threaded rod 22. In this way, the center of the tablecloth can be quickly aligned with the corner of the tripod 3, reducing the adjustment time and improving the efficiency of subsequent edge folding. After the tablecloth is placed on the tripod, it is folded in half and passed between several limiting rollers 6, and finally fixed on the storage roller 7. At this time, the first motor 5 and the second motor 8 can be started at the same time, so that they drive the tablecloth unwinding roller 4 and the storage roller 7 to rotate respectively, and perform unwinding and winding processing of the tablecloth.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
