Description

Technical Field

[0001] The invention relates to the technical field of pipe depth cutting, in particular to a clothes drying rack manufacturing device with adjustable cutting depth. Background Art

[0002] Clothes rack manufacturing is a key branch of household goods production, primarily involving the processing of various materials (such as metal and plastic tubes) into clothes rack products. The manufacturing process typically includes multiple steps, including material procurement, cutting, forming, and assembly. Deep cutting of the clothes rack tube is a critical step in the forming process, directly affecting the structural strength, aesthetics, and performance of the clothes rack.

[0003] Existing clothes drying rack manufacturing technology is plagued by complex and inefficient cutting depths, particularly when cutting the same depth across different calibers. Specifically, traditional equipment often requires individual adjustment of cutting depth for each caliber. This process is not only time-consuming and labor-intensive, but also prone to inconsistent cutting depths due to human error, impacting the overall quality of the clothes drying rack. Furthermore, when processing a large number of different calibers, frequently adjusting cutting depths significantly reduces production efficiency and increases costs.

[0004] More critically, existing technology lacks the ability to automatically adapt to the mixed processing of clothes drying rack tubes of varying diameters. This means that operators must stop the machine to adjust each time a different diameter is encountered, preventing continuous and efficient automated production. This limitation not only restricts the expansion of production but also makes it difficult to meet market demand for diversified and personalized clothes drying rack products.

[0005] For this reason, we propose a clothes drying rack manufacturing equipment with adjustable cutting depth. Summary of the Invention

When the lifting seat descends to the point where the cutting blade completes the deep cutting of the clothes drying rack tube, the roller contacts the inclined plate to cause the sliding plate to drive the locking tongue to separate from the outer float.

[0014] As a further description of the above technical solution: there is a gap between the end face gear 1 and the telescopic rod thereon, and when the locking tongue abuts against the outer floating surface, the hydraulic column is in a tensile deformation state.

[0015] As a further description of the above technical solution: the opening and closing mechanism includes a base plate arranged on a vertical frame, and two eccentric wheels are rotatably arranged on the base plate.

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See also Figures 1-13 The embodiment of the present invention provides a technical solution: a clothes drying rack manufacturing device with adjustable cutting depth, comprising a feeding mechanism and a driving mechanism provided on a frame 1, wherein a cutting piece is provided on the driving mechanism. After the clothes drying rack tube is fed through the feeding mechanism, the driving mechanism drives the cutting piece to cut the clothes drying rack tube;

[0041] In one embodiment of the present invention, the feeding mechanism includes a horizontal frame 10 mounted on the frame 1, and a conveying member 1 4 and a conveying member 2 6 are provided on the horizontal frame 10. Pullies are evenly spaced on the conveying member 1 4 and the conveying member 2 6, and a gap is left between the pulleys on the conveying member 1 4 and the pulleys on the conveying member 2 6 for the clothes drying rack tube to pass through. The conveying member 2 6 and the horizontal frame 10 are elastically arranged so that the gap between the conveying member 1 4 and the conveying member 2 6 is adjustable to feed clothes drying rack tubes of different widths and thicknesses. When feeding is required, the clothes drying rack tube can be inserted into the gap between the conveying member 1 4 and the conveying member 2 6 to feed the clothes drying rack tube. After the clothes drying rack tube is conveyed to the maximum stroke, the driving mechanism is started, and the clothes drying rack tube can be cut to a certain depth by the cutting member.

[0042] The cam 36 is connected to the drive mechanism 31 and the drive mechanism 36 is connected to the drive mechanism 31 by the screw rod 31 and the screw rod 31 is connected to the drive mechanism 31 by the screw rod 31.

[0043] It should be noted that the number of groups of screw rods 31, connecting parts and shafts 36 on one frame 1 is preferably two;

[0044] In order to improve the cutting effect of multiple clothes drying rack tubes, the slider 8 is further provided with a locking piece that abuts against the connecting part. When the driving mechanism is in the started state, the locking piece is used to stably transmit the power of the connecting part shaft 36 to the screw rod 31 to prevent the power transmission from being interrupted. In addition, the clothes drying rack manufacturing equipment with adjustable cutting depth also includes an opening and closing mechanism, which is provided on the vertical frame 12 and connected to the locking piece. The slider 8 is also provided with a wedge block 13, which is fed to the clothes drying rack tube through the feeding mechanism until it abuts against the wedge block 13. When the driving mechanism is started to make the cutting piece descend to complete the deep cutting of the clothes drying rack tube, the opening and closing mechanism is used to separate the locking piece and interrupt the power transmission of the driving mechanism. When the driving mechanism is driven in the reverse direction, the opening and closing mechanism is also used to abut the locking piece against the connecting part again.

[0045] When the feeding mechanism feeds the plurality of clothes drying rack tubes, the plurality of clothes drying rack tubes will collide with the wedge block 13. At this time, the feeding is completed, and the driving mechanism is started to press the plurality of cutting members downward to perform deep cutting on the clothes drying rack tubes. After cutting to a certain depth, the opening and closing mechanism separates the locking member from the connecting portion. At this time, the power transmission from the connecting portion to the driving mechanism is interrupted, the screw rod 31 stops rotating, and the cutting member stops moving, thereby achieving a uniform cutting depth for the plurality of clothes drying rack tubes. When the driving mechanism is driven in the reverse direction, the connecting member is also enabled to re-establish power transmission, so that the cutting member returns to its original position.

[0046] In order to further improve this effect, in another embodiment of the present invention, the connecting portion includes an end face gear 1 81 and an end face gear 2 82 that mesh with each other, wherein the end face gear 1 81 is mounted on the telescopic rod through a hydraulic column 83, and the end face gear 2 82 is provided on the telescopic rod and is rotatably connected to the slider 8. The telescopic rod on the end face gear 1 81 is movably inserted into the screw rod 31, and the telescopic rod on the end face gear 2 82 is movably inserted into the shaft 36. In this way, when the shaft 36 rotates, it can drive the screw rod 31 to rotate through the two telescopic rods and the meshing end face gear 1 81 and the end face gear 2 82.

[0047] It should be noted here that the driving mechanism includes a driving motor 3 mounted on the frame 1, and a driving shaft 36 is mounted on the output end of the driving motor 3. A synchronous belt 32: driving shaft 36; 33 is installed between the end of the driving shaft 36 and the two sets of shafts 36 through a synchronous wheel. In this way, when the driving motor 3 is started, the two shafts 36 can be driven to rotate through the driving shaft 36 and the synchronous belt 32: driving shaft 36; 33, thereby rotating the screw rod 31 through the connecting part, so that the cutting pieces on the two screw rods 31 can be simultaneously lowered, thereby simultaneously performing deep cutting on the two sets of feeding clothes drying rack tubes through the two cutting pieces;

[0048] When the clothes drying rack tube is fed through the feeding mechanism, the clothes drying rack tube contacts the wedge block 13. Since one side of the wedge block 13 is a slope, the clothes drying rack tube contacts the slope, which will push the wedge block 13 upward, thereby moving the slider 8 upward. Here, due to the setting of the locking member and the end gear 2 82, the end gear 1 81 and the end gear 2 82 move upward at the same time until the clothes drying rack tube is fed to the maximum stroke (the top side surface of the clothes drying rack tube contacts the bottom of the wedge block 13, and the end of the clothes drying rack tube The wedge block 13 is pressed against the surface of the slider 8 near the wedge block 13). At this time, the wedge block 13 is also moved upward to its maximum stroke after being pressed. The end gear 1 81, the end gear 2 82 and the locking member are also moved upward to their maximum stroke. At this time, the motor is started to press the multiple cutting members downward to achieve deep cutting of multiple clothes drying rack tubes. At the same time, after the cutting is completed, the locking member is separated from the connecting part by the opening and closing mechanism. At this time, the power transmission from the connecting part to the shaft 36 is interrupted, and the cutting action of the cutting member is stopped.

[0049] It should be noted here that when the thicknesses of the clothes drying rack tubes transported in the two conveying mechanisms are different, the two clothes drying rack tubes will cause the wedge blocks 13 on both sides to be lifted to different heights. At this time, when the driving motor 3 is started to press the two cutting pieces down for cutting, due to the different heights of the wedge blocks 13 on both sides, the heights of the sliders 8 are also different, so that the heights of the locking pieces are also different. In this way, when the cutting piece is pressed down and cuts the clothes drying rack tubes with different diameters on both sides, due to the different heights of the locking pieces, the position where the opening and closing mechanism abuts against the locking piece is also different. The cutting piece cutting the clothes drying rack tube with a larger diameter will stop descending first, and the cutting piece cutting the clothes drying rack tube with a smaller diameter will stop cutting later. In this way, since the height of the upper surface of the clothes drying rack tube with a larger diameter is higher, and the height of the upper surface of the clothes drying rack tube with a smaller diameter is lower, the clothes drying rack tube with a larger diameter will stop descending first. The cutting piece for cutting the clothes hanger pipe moves downward at a lower depth, while the cutting piece for cutting the clothes hanger pipe with a smaller diameter moves downward at a greater depth. This difference makes up for the difference in upper surface height caused by the different diameters of the two clothes hanger pipes, so that the clothes hanger pipes of different diameters are cut to the same depth. The same driving motor 3 can be used as a drive, so that the two cutting pieces can cut to the same depth when cutting the two clothes hanger pipes of different diameters, so that the specifications of the cutting edges are the same. There is no need to adjust the cutting depth separately, but the clothes hanger pipes of different diameters can be automatically cut to the same depth for clothes hanger pipes of different diameters, thereby reducing the cutting difficulty and eliminating the need for manual control. The clothes hanger pipes are suitable for cutting operations of various clothes hanger pipes of different diameters. The same cutting depth allows clothes hanger pipes of different specifications to be assembled, and the universality is better.

[0050] In another embodiment of the present invention, the locking member includes a sliding plate 5 slidably mounted on the slider 8, and a locking tongue 51 is fixedly provided on the sliding plate 5 and overlapped on the surface of the outer flank 52. The outer flank 52 is fixedly mounted on the outer peripheral side of the end face gear 1 81, and the outer flank 52 is arranged obliquely downward, so that when the locking tongue 51 abuts against the outer flank 52, the end face gear 1 81 and the end face gear 2 82 form a whole. The locking tongue 51 abuts against the outer flank 52, thereby pressing the end face gear 1 81 against the end face gear 2 82. When the shaft 36 rotates, the power of the shaft 36 is stably transmitted, thereby preventing vibration during cutting from causing unstable power transmission and affecting the cutting effect.

[0051] In another embodiment of the present invention, the cutting piece includes a lifting seat 2 and a cutting blade 21. The lifting seat 2 is threadedly mounted on the screw 31, and the cutting blade 21 is mounted on the lifting seat 2. The opening and closing mechanism includes a vertical plate 71 fixed to the lifting seat 2 and a roller 72 mounted on the vertical plate 71. The sliding plate 5 is provided with an inclined plate 7 corresponding to the position of the roller 72. When the lifting seat 2 is lowered to the point where the cutting blade 21 completes the deep cutting of the clothes drying rack tube, the roller 72 contacts the inclined plate 7 to enable the sliding plate 5 to drive the locking tongue 51 to separate from the outer float 52. When the driving motor 3 is started, the two screws 31 rotate simultaneously, and the two lifting seats 2 carry the two cutting The cutting blade 21 descends to cut the clothes drying rack tube. During the cutting process, the roller 72 on the vertical plate 71 abuts the inclined plate 7, thereby pushing the sliding plate 5 away from the outer flank 52, so that the locking tongue 51 is away from the outer flank 52 until the locking tongue 51 is separated from the outer flank 52. Since there is a gap between the end gear 1 81 and the telescopic rod thereon, and when the locking tongue 51 abuts against the surface of the outer flank 52, the hydraulic column 83 is in a tensile deformation state, the locking tongue 51 is separated from the outer flank 52, and the hydraulic column 83 recovers its deformation, pulling the end gear upward, and the end gear 1 81 and the end gear 2 82 are separated. At this time, the transmission of the shaft 36 is terminated, and the screw rod 31 stops rotating.

[0052] When the two feeding mechanisms feed clothes drying rack tubes of different diameters, the heights of the wedge block 13 rise to different levels, so that the heights of the sliding plate 5 and the inclined plate 7 on the slider 8 are different. For clothes drying rack tubes with larger diameters, the wedge block 13 rises to a higher level, so that the inclined plate 7 on the sliding plate 5 at a higher position will first abut against the roller 72, thereby first stopping the rotation of the screw rod 31. Conversely, the inclined plate 7 on the sliding plate 5 at a lower position will then abut against the roller 72, thereby subsequently stopping the rotation of the clothes drying rack tubes near the smaller diameters. The screw rod 31 stops rotating, and the cutting of clothes drying rack pipes of different diameters is realized in turn, while the cutting depth is kept consistent. The overall use effect is better, and there is no need to manually adjust the cutting depth according to the clothes drying rack pipes of different diameters. Instead, the cutting depth can be automatically adapted according to the clothes drying rack pipes of different diameters, so that the cutting depth of clothes drying rack pipes of different diameters is kept consistent, so as to facilitate subsequent assembly. The overall practicality is better and the operation is convenient. It only needs to control the feeding, and is suitable for promotion and use.

[0053] It should be noted that, in order to enable the two telescopic rods to maintain power transmission while extending and retracting, the inner walls of the screw rod 31 and the shaft 36 are both provided with grooves, and the outer surfaces of the two telescopic rods are also provided with protrusions 34: telescopic rod; 35, which are adapted to the size of the grooves and slidably fit into the grooves. In this way, the telescopic rods can maintain power transmission when the slider 8 moves. In order to improve lubrication, wear-resistant grease can be applied to the connection between the grooves and the protrusions 34: telescopic rod; 35 to reduce friction and prevent jamming.

[0054] It should also be noted that the opening and closing mechanism also includes a base plate 9 provided on the vertical frame 12, and two eccentric wheels 96 are rotatably provided on the base plate 9. The two eccentric wheels 96 are connected to the shaft 36 through a docking piece. When the shaft 36 is in clockwise / counterclockwise rotation, the docking piece is used to make the two eccentric wheels 96 rotate alternately. When the drive motor 3 is driven in the forward direction (cutting the clothes drying rack tube), one of the two eccentric wheels 96 of the docking piece rotates and the other does not rotate. When the drive motor 3 is driven in the reverse direction (to restore the cutting piece to its original position), the rotation state of the two eccentric wheels 96 changes.

[0055] In one embodiment, the docking member includes two groups of springs 98 provided on the shaft 36. Both springs 98 are provided with push blocks 99. One side of the two push blocks 99 is an inclined surface, and the other side is a straight surface. The inclined surfaces and the straight surfaces of the two push blocks 99 are arranged in opposite directions. One-way grooves 97 with opposite opening directions are provided on the inner sidewall surfaces of the two eccentric wheels 96. When the drive motor 3 drives the shaft 36 to rotate in the forward direction, one group of push blocks 99 pushes the one-way groove 97 to rotate the eccentric wheel 96, while the other group is stationary. Conversely, the motion states of the two eccentric wheels 96 are swapped.

[0056] After the clothes drying rack tube is cut by the cutting blade 21, the cutting blade 21 needs to be restored to its original position. At this time, the driving click is started to drive it in the reverse direction. At this time, a set of eccentric wheels 96 are started to rotate. Since the eccentric wheels 96 are all arranged at the eccentric position on the outer peripheral side of the shaft 36, and the eccentric positions of the two eccentric wheels 96 are symmetrically arranged with the shaft 36 as the center, and the opening and closing mechanism also includes a ring 92 rotatably arranged on the surface of the bottom plate 9, and the inner wall of the ring 92 is provided with a cylinder 910, When the eccentric wheels 96 rotate alternately, the cylinder 910 abuts against the ends of the two eccentric wheels 96 alternately, and a contact wheel 93 is provided on the outer side of the ring 92; the opening and closing mechanism also includes a driving ring 91, and the driving ring 91 is provided with protrusions 95 on both sides close to the locking tongue 51 and away from the locking tongue 51, and the driving ring 91 is connected to the sliding plate 5 through a connecting frame 94. When the eccentric wheels 96 abut against the cylinder 910 and cause the ring 92 to rotate, the contact wheel 93 abuts against the surface of the protrusion 95;

[0057] When the drive motor 3 is driven in the reverse direction, one of the eccentric wheels 96 rotates, and when it rotates, it pushes the cylinder 910 to rotate the ring 92. Due to the design of the eccentric wheel 96, the distance between its end position and the cylinder 910 increases after rotating half a circle, so that the eccentric wheel 96 is separated from the cylinder 910. At this time, the rotation of the eccentric wheel 96 will no longer contact the cylinder 910. That is to say, when the drive motor 3 is driven in the reverse direction, the rotating eccentric wheel 96 will push the cylinder 910 to rotate the ring 92. The contact wheel 93 rotates half a circle, thereby rotating half a circle. When the contact wheel 93 rotates half a circle, it squeezes the protrusion 95, thereby moving the drive ring 91, so that the sliding plate 5 and the locking tongue 51 are close to the outer flank 52 through the connecting frame 94. Since the outer flank 52 is set to be tilted downward, the locking tongue 51 is now in contact with the outer flank 52 again, so that the end gear 1 81 on the outer flank 52 is re-engaged with the end gear 2 82, and the screw rod 31 resumes rotation, thereby causing the cutting blade 21 to return to its original position upward.

[0058] It should be noted here that when the cutting blade 21 moves upward to the initial position and starts the next cutting, the new clothes drying rack tube that needs to be cut is transported to its position, and then the drive motor 3 is started. At this time, the rotation state of the two eccentric wheels 96 changes, and since the eccentric positions of the two eccentric wheels 96 are symmetrically arranged with the shaft 36 as the center, the eccentric wheels 96 start to rotate and push the cylinder 910 to the other side and then separate from the cylinder 910. In this process, the sliding plate 5 and the locking tongue 51 will be separated from the outer float 52 through the driving ring 91 and the connecting frame 94. However, since the curvature of the protrusion 95 on the side close to the locking tongue 51 is greater than the curvature of the protrusion 95 on the side away from the locking tongue 51, the locking tongue 51 will not be completely separated from the outer float 52. Since the teeth of the end gear 1 81 and the end gear 2 82 have a certain depth, When the gear 71 is lowered, the roller 72 is in contact with the outer float 52, thereby completely separating the locking tongue 51 from the outer float 52, thereby cutting off the power.

[0059] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
