Abstract

This invention relates to the field of UV-curable dry hose folding and storage technology, specifically to an automatic folding and storage device for UV-curable dry hoses. The device includes a horizontal moving mechanism and two sets of single-sided blocking mechanisms. Both single-sided blocking mechanisms are fixedly installed on the displacement seat of the horizontal moving mechanism. Each single-sided blocking mechanism includes a rotating stop shaft, a rotating mechanism, and a fixed-distance lifting mechanism. This automatic folding and storage device for UV-curable dry hoses can position the left and right sides of the hose bend during the folding process, preventing protrusions or indentations on either side.

Each upward movement only occurs when the rotating stop shaft is within a vertical groove, preventing the rotating stop shaft from pushing the hose upwards.

Description

Technical Field

[0001] This invention relates to the field of light-curing dry hose folding and storage technology, specifically to an automatic folding and storage device for light-curing dry hoses. Background Technology

[0002] After processing, the UV-cured flexible tube needs to be folded on a wooden pallet before being sent to a packaging machine for lamination. During folding, the tube is conveyed downwards via a high platform, and then a horizontal moving mechanism on the ground moves the wooden pallet left and right, causing the tube to be bent and stacked layer by layer. However, this folding method cannot guarantee that both sides of the bends will remain in the same vertical position after multiple folds, resulting in protrusions or indentations on the sides. This leads to poor overall flatness and a risk of scattering during transport. Furthermore, protruding tubes may drape to the sides; if the sides are subjected to force during transport, the internal adhesive may be squeezed, causing changes in thickness. This results in inconsistent thickness inside the tube after UV curing, affecting the repair effect.

[0003] Therefore, it is necessary to design an automatic folding and storage device for light-cured flexible tubes that can position the left and right sides of the bend during the folding process to prevent the left and right sides from protruding or indenting. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an automatic folding and storage device for light-cured flexible tubes, which positions the left and right sides of the tube's bend to prevent any protrusions or indentations on the left and right sides.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The present invention provides an automatic folding and storage device for light-curing dry hoses, including a horizontal moving mechanism and two sets of single-sided blocking mechanisms. Both single-sided blocking mechanisms are fixedly installed on the displacement seat of the horizontal moving mechanism. Each single-sided blocking mechanism includes a rotating stop shaft, a rotating mechanism, and a fixed-distance lifting mechanism. The rotating mechanism is fixedly installed on the lifting seat of the fixed-distance lifting mechanism, and the rotating stop shaft is fixedly installed on the rotating seat of the rotating mechanism. The rotating mechanism is used to push the rotating stop shaft to block the bent end of the hose, and the fixed-distance lifting mechanism is used to drive the rotating mechanism to move vertically upward. The initial heights of the two rotating stop shafts are staggered, and the height difference between the two rotating stop shafts is twice the thickness of the hose.

[0006] Preferably, each fixed-distance lifting mechanism includes a tensioning mechanism, a guide column, a lifting seat, a blocking frame, multiple blocking rods, multiple internal pressure mechanisms, and multiple external pulling mechanisms. The guide column is vertically fixedly installed on the displacement seat, and the lifting seat is vertically slidably installed on the guide column. The rotating mechanism is fixedly installed on the lifting seat. The tensioning mechanism is used to pull the lifting seat upward. The blocking frame is fixedly installed on the displacement seat. The end of the rotating stop shaft passes through the rotating clearance groove and is inserted into the upper part of the hose. The blocking frame has multiple rotating clearance grooves for the rotating stop shaft to rotate. The multiple rotating clearance grooves are connected by vertical grooves. The multiple blocking rods correspond one-to-one with the multiple rotating clearance grooves. The end of the blocking rod passes through the blocking frame and is inserted into the vertical groove. The blocking frame has sliding holes for the blocking rods to pass through. The internal pressure mechanism is fixedly installed on the blocking frame. The internal pressure mechanism is used to push the blocking rod to the top of the rotating stop shaft. The blocking rod is used to block the top of the rotating stop shaft. The external pulling mechanism is used to pull the blocking rod outward. The steel cable is locked in the groove of the roller.

[0007] Preferably, the external pulling mechanism includes an external pulling rod, a push rod, and a sliding column. A vertical rotating shaft one and a rotating shaft two are fixedly installed on the displacement seat. The external pulling rod is rotatably mounted on the rotating shaft one. A sliding column is fixedly installed on the top of the sliding plate. An oblong hole for inserting the sliding column is opened on the external pulling rod. The push rod is rotatably mounted on the rotating shaft two. One end of the push rod abuts against the external pulling rod, and the other end of the push rod contacts the rotating stop shaft on another single-sided blocking mechanism. The rotating stop shaft of the other single-sided blocking mechanism is located above the rotating stop shaft of the single-sided blocking mechanism.

[0008] Preferably, the fixed-distance lifting mechanism further includes two vertical guide plates and multiple elastic limiting mechanisms respectively installed on the two vertical guide plates. The two vertical guide plates are located on both sides of the rotation axis of the push rod. The two rows of elastic limiting mechanisms are used to provide elastic force to both sides of the push rod. Each elastic limiting mechanism includes a second guide post, a retaining ring, a first spring, and a circular baffle. The second guide post can be horizontally slidably installed on the vertical guide plate. The retaining ring is fixedly installed on the second guide post. One end of the second guide post abuts against the push rod. The circular baffle is fixedly installed on the other end of the second guide post. The first spring is used to provide elastic force to the second guide post away from the vertical guide plate.

[0009] Preferably, each internal pressure mechanism further includes a second spring and a third guide post. The third guide post is horizontally fixedly installed on the blocking frame. A vertically positioned vertical limiting plate is fixedly installed on the side of the blocking frame. One end of the third guide post is fixedly connected to the vertical limiting plate. The slide plate is horizontally slidably installed on the third guide post. The second spring is used to provide elastic force for the slide plate to conform to the blocking frame.

[0010] Preferably, the multiple push rods on the left and right rows of external pulling mechanisms are distributed in an alternating manner, and the ends of the two rows of push rods intersect each other.

[0011] Preferably, the tensioning mechanism includes a steel rope, a counterweight, a roller, and a wheel seat. The wheel seat is fixedly installed on the top of the guide column, the roller is rotatably installed on the wheel seat, one end of the steel rope is fixedly connected to the counterweight, and the other end of the steel rope is fixedly connected to the lifting seat.

[0012] Preferably, the rotating mechanism includes an electric push rod, a rotating rod, and a rotating shaft three. One end of the rotating shaft is fixedly connected to one end of the rotating rod, the other end of the rotating rod is hinged to the output end of the electric push rod, the tail of the electric push rod is hinged to the lifting seat, the rotating shaft three is fixedly installed on the lifting seat, and the middle part of the rotating rod is hinged to the rotating shaft three.

[0013] Preferably, a gap is left on the inner side of the two rotating retaining shafts.

[0014] Preferably, the horizontal moving mechanism further includes a slide rail and a ball screw. The slide rail is fixedly installed on the top of the moving vehicle. The displacement seat is horizontally slidable on the slide rail via the slide seat. The ball screw is fixedly installed on the moving vehicle. The screw nut on the ball screw is fixedly connected to the displacement seat. One end of the ball screw is connected to a drive motor that drives the screw to rotate.

[0015] The beneficial effects of this invention are as follows: This automatic folding and storage device for light-curing flexible tubes can position the left and right sides of the bend in the flexible tube during the folding process, preventing protrusions or indentations on the left and right sides. Simultaneously, its lifting mechanism is driven by a fixed-distance lifting mechanism, while a rotating mechanism pushes a rotating stop shaft to rotate, allowing the other rotating stop shaft to rise. Each upward movement only occurs when the rotating stop shaft is within the vertical groove, avoiding the probability of the rotating stop shaft pushing the flexible tube upwards. Furthermore, each upward movement ensures the thickness of two flexible tubes, preventing insufficient lifting height due to lead screw failure and subsequent compression of the flexible tube during rotation. In this way, the other rotating stop shaft can only screw into the flexible tube after the first rotating stop shaft has rotated out of the flexible tube's enclosure. This avoids the risk of clamping and deforming the flexible tube due to simultaneous rotation of two rotating stop shafts. Moreover, it eliminates the need for multiple electrically controlled external pulling mechanisms, employing mechanical drive instead, thus avoiding tangled wiring. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: This invention provides an automatic folding and storage device for light-cured flexible tubes, such as... Figure 1-10 As shown, the system includes a horizontal moving mechanism 2 and two sets of single-sided blocking mechanisms. Both single-sided blocking mechanisms are fixedly installed on the displacement seat 2a of the horizontal moving mechanism 2. Each single-sided blocking mechanism includes a rotating stop shaft 3, a rotating mechanism 4, and a fixed-distance lifting mechanism 5. The rotating mechanism 4 is fixedly installed on the lifting seat 5c of the fixed-distance lifting mechanism 5, and the rotating stop shaft 3 is fixedly installed on the rotating seat of the rotating mechanism 4. The rotating rod 4b is the rotating seat. The rotating mechanism 4 is used to push the rotating stop shaft 3 to block the bent end of the hose 11. The fixed-distance lifting mechanism 5 is used to drive the rotating mechanism 4 to move vertically upwards. The horizontal moving mechanism 2 is fixedly installed on the moving vehicle 1. Before each folding and storage of the hose, the horizontal moving mechanism 2 is moved to a position directly below the hose 11. When the hose 11 falls from a height, it has already been rolled flat by the rolling equipment on the high platform, resulting in a constant thickness. To facilitate the transport of the hose 11, a wooden support 10 is placed above the displacement seat 2a, and the hose 11 falling from a height will land on the wooden support 10. During stacking, the displacement seat 2a swings left and right, causing the hoses 11 to be stacked layer by layer on the wooden support 10. At each layer's bend, the corresponding rotating mechanism 4 rotates the rotating stop shaft 3 to block the bent end of the hose 11. Two rotating mechanisms 4 drive two rotating stop shafts 3 to rotate, positioning the left and right folded sides of the hose 11. After each layer of hose 11 is positioned, the fixed-distance lifting mechanism 5 raises the rotating stop shaft 3 a certain distance, with the height difference being twice the thickness of the hose 11. The initial heights of the two rotating stop shafts 3 are staggered, with the height difference between the two rotating stop shafts being twice the thickness of the hose 11.

[0030] To ensure that the rotating stop shaft 3 can only be lifted upwards after rotating away from the hose 11, each fixed-distance lifting mechanism 5 includes a tensioning mechanism 5a, a guide post 5b, a lifting seat 5c, a blocking frame 5d, multiple blocking rods 5e, multiple internal pressure mechanisms 5f, and multiple external pulling mechanisms 5h. The guide post 5b is vertically fixed on the displacement seat 2a, the lifting seat 5c is vertically slidably mounted on the guide post 5b, the rotating mechanism 4 is fixedly mounted on the lifting seat 5c, the tensioning mechanism 5a is used to pull the lifting seat 5c upwards, the blocking frame 5d is fixedly mounted on the displacement seat 2a, and the end of the rotating stop shaft 3 passes through the rotating clearance groove 5d1 and inserts above the hose 11, preventing... The baffle 5d has multiple rotating clearance grooves 5d1 for the rotating baffle shaft 3 to rotate. These grooves are connected by vertical grooves 5d2. Multiple blocking rods 5e correspond one-to-one with each of the rotating clearance grooves 5d1. The ends of the blocking rods 5e pass through the baffle 5d and are inserted into the vertical grooves 5d2. The baffle 5d has sliding holes for the blocking rods 5e to pass through. An internal pressure mechanism 5f is fixedly installed on the baffle 5d. The internal pressure mechanism 5f pushes the blocking rods 5e to the top of the rotating baffle shaft 3, thus blocking the top of the rotating baffle shaft 3. An external pulling mechanism 5h pulls the blocking rods 5e outwards. The steel cable 5a1 is secured in the groove of the roller 5a3. When the hose 11 is folded, the rotating baffle shaft 3 will... Figure 3 The positions shown indicate that the states of the rotating stop shaft 3 and the rotating mechanism 4 are simultaneously changing. Figure 4 This can also be seen in the diagram. After folding, the rotating mechanism 4 pulls the rotating stop shaft 3 to rotate, causing the rotating stop shaft 3 to rotate into the vertical groove 5d2. Then, the external pulling mechanism 5h pulls the blocking rod 5e away from the rotating stop shaft 3. The rotating stop shaft 3, which is blocking it, will be pulled upward by the stretching mechanism 5a, together with the lifting seat 5c and the rotating mechanism 4, by a distance of one workstation. The direction of movement is as follows: Figure 5 As indicated by the arrows, the distance between each workstation is twice the thickness of the aforementioned hose 11. This upward pulling method ensures that each upward movement only occurs when the rotating stop shaft 3 is within the vertical groove 5d2, preventing the rotating stop shaft 3 from pushing the hose 11 upwards. This is because each upward push would deform the adhesive inside the hose 11, requiring excessive rework. Furthermore, each upward movement ensures a thickness equivalent to two hose 11 sections, preventing insufficient upward movement due to screw malfunction and subsequent compression of the hose 11 during rotation.

[0031] To ensure that one rotating stop shaft 3 can rotate out of the inside of the hose 11 before the other rotating stop shaft 3 can be screwed into the hose 11, the outer pulling mechanism 5h includes an outer pulling rod 5h1, a push rod 5h3, and a sliding column 5h4. The displacement seat 2a is fixedly provided with a vertical rotating shaft 1 5h2 and a rotating shaft 2 5h5. The outer pulling rod 5h1 is rotatably mounted on the rotating shaft 1 5h2. The top of the sliding plate 5f1 is fixedly provided with a sliding column 5h4. The outer pulling rod 5h1 has an oblong hole for the sliding column 5h4 to be inserted. The push rod 5h3 is rotatably mounted on the rotating shaft 2 5h5. One end of the push rod 5h3 abuts against the outer pulling rod 5h1, and the other end of the push rod 5h3 contacts the rotating stop shaft 3 on another single-sided blocking mechanism. The rotating stop shaft 3 of the other single-sided blocking mechanism is located above the rotating stop shaft 3 of the single-sided blocking mechanism. When the rotating stop shaft 3 is blocked by the stop rod 5e and cannot rise, it can be rotated 90 degrees by another rotating stop shaft 3, such as... Figure 7 As shown, this will cause the rotating stop shaft 3 to contact the end of the push rod 5h3. At this point, the rotating stop shaft 3 does not stop moving; it continues to rotate 1-3 degrees. The range of degrees is selected as a fixed value based on the actual needs of the equipment. This is achieved by moving along... Figure 7 The arrow shown rotates in the direction of movement, which will present... Figure 8 The state shown is as follows. At this time, the push rod 5h3 will rotate along the rotating shaft 5h5, and the push rod 5h3 will push the outer pull rod 5h1 to rotate. Finally, the outer pull rod 5h1 will rotate through the slide column 5h4 to push the blocking rod 5e out from the top of the rotating stop shaft 3, so that the rotating stop shaft 3 can finally move upward. In this way, only after the rotating stop shaft 3 rotates out of the inside of the hose 11 can the other rotating stop shaft 3 be screwed into the hose 11. This avoids the risk of clamping and deforming the hose 11 due to the simultaneous rotation of two rotating stop shafts 3. At the same time, it also eliminates the need for a structure with multiple electrically controlled external pull mechanisms 5h, and instead uses mechanical drive to avoid the mess of the wiring harness. Furthermore, if the other rotating stop shaft 3 moves to the top of the hose 11 first, it will be difficult for the rotating stop shaft 3 to move between the two layers of hose 11 when it is screwed out.

[0032] The fixed-distance lifting mechanism 5 also includes two vertical guide plates 5x and multiple elastic limiting mechanisms 5j respectively installed on the two vertical guide plates 5x. The two vertical guide plates 5x are located on both sides of the rotation axis of the push rod 5h3. The two rows of elastic limiting mechanisms 5j are used to provide elastic force to both sides of the push rod 5h3. Each elastic limiting mechanism 5j includes a second guide post 5j1, a retaining ring 5j2, a first spring 5j3 and a circular baffle 5j4. The second guide post 5j1 can be horizontally slidably installed on the vertical guide plate 5x. The retaining ring 5j2 is fixedly installed on the second guide post 5j1. One end of the second guide post 5j1 abuts against the push rod 5h3. The circular baffle 5j4 is fixedly installed on the other end of the second guide post 5j1. The first spring 5j3 is used to provide elastic force to the second guide post 5j1 away from the vertical guide plate 5x. Spring 5j3 is fitted onto guide post 5j1. One end of spring 5j3 abuts against retaining ring 5j2, and the other end abuts against vertical guide plate 5x. By applying elastic force to retaining ring 5j2 through spring 5j3, guide post 5j1 will abut against push rod 5h3. Since both rows of guide posts 5j1 abut against push rod 5h3, the position of push rod 5h3 can be positioned. At the same time, when push rod 5h3 is pushed to rotate, spring 5j3 can be compressed, providing space for the rotation of push rod 5h3.

[0033] Each internal pressure mechanism 5f also includes a second spring 5f2 and a third guide post 5f3. The third guide post 5f3 is horizontally fixedly mounted on the blocking frame 5d. A vertically positioned vertical limiting plate 5d3 is fixedly mounted on the side of the blocking frame 5d. One end of the third guide post 5f3 is fixedly connected to the vertical limiting plate 5d3. The sliding plate 5f1 is horizontally slidably mounted on the third guide post 5f3. The second spring 5f2 provides elastic force to the sliding plate 5f1 to conform to the blocking frame 5d. The second spring 5f2 is sleeved on the third guide post 5f3, with one end of the second spring 5f2 abutting against the sliding plate 5f1 and the other end abutting against the vertical limiting plate 5d3. When the rotating shaft 5h2 rotates, it pulls the sliding plate 5f1 to slide along the third guide post 5f3, thus compressing the second spring 5f2.

[0034] The multiple push rods 5h3 ​​on the left and right rows of external pulling mechanisms 5h are staggered, and the ends of the two rows of push rods 5h3 ​​intersect each other. In this intersecting manner, after the hoses 11 are stacked, when the rotating stop shaft 3 needs to be lowered, a rod-shaped tool can be used to push the two rows of push rods 5h3 ​​to rotate simultaneously, so that all the blocking rods 5e retract inward, and the rotating stop shaft 3 can move downward under the push of the worker.

[0035] The tensioning mechanism 5a includes a steel rope 5a1, a counterweight 5a2, a roller 5a3, and a wheel seat 5a4. The wheel seat 5a4 is fixedly installed on the top of the guide column 5b. The roller 5a3 is rotatably mounted on the wheel seat 5a4. One end of the steel rope 5a1 is fixedly connected to the counterweight 5a2, and the other end of the steel rope 5a1 is fixedly connected to the lifting seat 5c. The weight of the counterweight 5a2 pulls the lifting seat 5c upward, ensuring a constant upward tension on the lifting seat 5c, thus allowing control over the upward movement speed of the rotating stop shaft 3.

[0036] The rotating mechanism 4 includes an electric push rod 4a, a rotating rod 4b, and a rotating shaft 3 4c. One end of the rotating shaft 3 is fixedly connected to one end of the rotating rod 4b, and the other end of the rotating rod 4b is hinged to the output end of the electric push rod 4a. The tail of the electric push rod 4a is hinged to the lifting seat 5c. The rotating shaft 3 4c is fixedly installed on the lifting seat 5c, and the middle part of the rotating rod 4b is hinged to the rotating shaft 3 4c. By controlling the electric push rod 4a to work, the electric push rod 4a can push the rotating rod 4b to rotate along the rotating shaft 3 4c, which in turn causes the rotating rod 4b to drive the rotating shaft 3 to rotate.

[0037] There is a gap between the inner sides of the two rotating stop shafts 3. The gap between the inner sides of the two rotating stop shafts 3 ensures that when the bottom rotating stop shaft 3 rises, the two rotating stop shafts 3 can avoid collision.

[0038] The horizontal moving mechanism 2 also includes a slide rail 2b and a ball screw 2c. The slide rail 2b is fixedly installed on the top of the moving vehicle 1. The displacement seat 2a is horizontally mounted on the slide rail 2b via a sliding block. The ball screw 2c is fixedly installed on the moving vehicle 1. The screw nut on the ball screw 2c is fixedly connected to the displacement seat 2a. One end of the ball screw 2c is connected to a drive motor that drives the screw to rotate. By controlling the motor to work, the ball screw 2c can be rotated, and the ball screw 2c will drive the displacement seat 2a to slide horizontally along the slide rail 2b via the screw nut.

[0039] In use, the horizontal moving mechanism 2 drives the displacement seat 2a to move horizontally, which in turn drives the wooden support 10 to move horizontally, and the hose 11 will be stacked on the wooden support 10. At each turning point, the rotating mechanism 4 pushes the rotating stop shaft 3 to rotate above the hose 11, limiting the turning point. After one layer of hose 11 is stacked, the rotating mechanism 4 pushes the rotating stop shaft 3 to rotate out. When it reaches the final position, the rotating stop shaft 3 pushes the push rod 5h3 to rotate, causing the corresponding blocking rod 5e to be pulled out. At this time, the lower rotating stop shaft 3 is pulled upward by the stretching mechanism 5a, and then another rotating mechanism 4 drives the newly raised rotating stop shaft 3 to rotate, so that the newly raised rotating stop shaft 3 moves above the topmost hose 11, preparing for the stacking of the next layer of hose 11.

[0040] This automatic folding and storage device for UV-curing flexible tubes can position the left and right sides of the bend during the folding process, preventing protrusions or indentations on either side. The lifting mechanism is driven by a fixed-distance lifting mechanism, which in turn drives a rotating stop shaft to rotate, allowing the other rotating stop shaft to rise. Each upward movement only occurs when the rotating stop shaft is within its vertical groove, preventing the possibility of the rotating stop shaft pulling the tube upwards. Furthermore, each upward movement ensures the thickness of two tubes is maintained, preventing insufficient lifting height due to lead screw failure and subsequent compression of the tube during rotation. This method ensures that the other rotating stop shaft can only screw onto the tube after the first rotating stop shaft has rotated out of the tube's enclosure. This avoids the risk of clamping and deforming the tube due to simultaneous rotation of two rotating stop shafts. Moreover, it eliminates the need for multiple electrically controlled external pulling mechanisms, employing mechanical drive instead to avoid tangled wiring.

[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
