Detailed implementation manners

[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention in conjunction with the drawings in the specification.

[0025] In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other.

[0027] Example 1, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , is the first embodiment of the present invention. This embodiment provides a storage device for conveniently storing knitted and woven goods for sale.

[0028] Storage base 1, the storage base 1 can be used to provide a storage position for boxed finished needle textiles; an installation frame 2 arranged on the top of the storage base 1, the installation frame 2 is used to provide an installation position for each component, and the installation frame 2 is threadedly connected and mutually communicated with the storage base 1, so that the needle textiles can effectively enter the interior of the storage base 1; an adjustment component 3, including a frame 38 arranged inside the installation frame 2, a lifting block 31 slid into the frame 38, a piston cylinder 32 arranged on the top of the lifting block 31, telescopic rods 33 with one-way valves arranged on both sides of the frame 38, a push seat 34 arranged at the output end of the telescopic rods 33, a sliding seat 35 movably arranged at one end of the frame 38, an electric valve 37 arranged outside the telescopic rods 33, and a sliding plate 36 slid into the sliding seat 35. There is a certain connection relationship between the piston cylinder 32 and the lifting block 31, and the piston rod 44 is connected to the lifting block 31. Therefore, when the piston rod 44 moves, the piston rod 44 will slide inside the piston cylinder 32. Thus, when the lifting block 31 rises and falls, the air inside the piston cylinder 32 can move through the pipeline. Therefore, it is injected into the interior of the telescopic rod 33 through the pipeline, so that the telescopic rod 33 can move. And a one-way valve is arranged at one end inside the telescopic rod 33, so that the air inside the piston cylinder 32 will not flow back into the interior of the piston cylinder 32. Moreover, a one-way valve is also arranged outside the piston cylinder 32, so that external air can enter the interior of the piston cylinder 32, and the air inside the piston cylinder 32 will not be discharged through the one-way valve outside the piston cylinder 32; the movement of the sliding seat 35 drives the push seat 34 to rotate around the rotation axis of the sliding seat 35. The sliding seat 35 and the push seat 34 are movably connected. Therefore, during the movement of the push seat 34, the sliding seat 35 will rotate around its axis, and during the movement of the sliding seat 35, the sliding plate 36 will slide inside the sliding seat 35.

[0029] During use, when the lifting block 31 rises, the lifting block 31 can drive the piston cylinder 32 to move. During the movement of the piston cylinder 32, the piston cylinder 32 can inject the air inside it into the interior of the telescopic rod 33 through an externally connected pipeline, and use the one-way valve at one end of the telescopic rod 33, so that the air will not leak from the interior of the piston cylinder 32. Thus, the telescopic rod 33 will push the push seat 34 to move. During the movement of the push seat 34, the push seat 34 can use the movable connection with the sliding seat 35, so that the sliding seat 35 can be adjusted in angle, and when the sliding seat 35 is adjusted in angle, the sliding plate 36 will move inside the sliding seat 35.

[0030] In summary, the piston cylinder 32 transmits air through a pipe shape. When the piston cylinder moves, it compresses the air and makes the air drive the telescopic rod 33 to extend, and then drives the push seat 34 to move linearly. The movable connection between the push seat 34 and the sliding seat 35 can convert the linear motion into the rotational motion of the sliding seat 35, so that the skateboard 36 can move. Such an operation method enables the device to automatically adjust the angle of the sliding seat according to the actual thickness of the boxed finished knitted textiles, so as to realize the accurate cavity storage of products with different thicknesses, greatly improving the convenience of classified storage.

[0031] Example 2, referring to Figure 3 and Figure 6 , is the second embodiment of the present invention. Different from the previous embodiment, it solves the problem of the rotation cylinder rising and injecting air into the telescopic cylinder.

[0032] An elevating assembly 4 is arranged inside the frame 38. The elevating assembly 4 includes an elevating groove 41. The elevating block 31 is slidably connected to the inside of the elevating groove 41. A rotating rod 42 is installed inside the elevating block 31 through a bearing. The rotating rod 42 is movably installed inside the elevating block 31 by using a bearing, and the elevating block 31 and the elevating groove 41 are slidably connected. Therefore, when the rotating rod 42 rises, the rotating rod 42 will drive the elevating block 31 to rise and fall inside the elevating groove 41.

[0033] The elevating assembly 4 further includes a piston rod 44. The piston rod 44 is fixed to the top of the elevating block 31. A rotating cylinder 43 is arranged in the middle of the rotating rod 42. The rotating rod 42 is fixed to the middle of the outer wall of the rotating cylinder 43 by using bolts. During the rotation of the rotating rod 42, the rotating rod 42 will drive the rotating cylinder 43 to rotate, and the piston rod 44 and the elevating block 31 are connected by bolts.

[0034] The top end of the piston rod 44 is provided with a piston plate 45. A first spring 46 is sleeved outside the piston rod 44. An infrared induction module 47 is arranged inside the frame 38. The piston rod 44 is located inside the piston cylinder 32. When the piston rod 44 moves, the piston rod 44 will drive the piston plate 45 to move, and the piston rod 44 and the piston plate 45 are fixedly connected by using bolts. The first spring 46 is sleeved on the outer wall of the piston rod 44 located inside the piston cylinder 32, and the infrared induction module 47 is fixed on one side of the frame 38 and can be used to cooperate with the electric valve 37 to realize the gas block processing of the telescopic rod 33.

[0035] During use, when the boxed finished knitted textiles come into contact with the rotating cylinder 43, the rotating cylinder 43 will drive the rotating rod 42 to move, the rotating rod 42 will drive the lifting block 31 to rise, the lifting block 31 will drive the piston rod 44 to rise, and when the piston rod 44 rises, the piston rod 44 will drive the piston plate 45 to rise, and the piston plate 45 will drive the first spring 46 to stretch. When the first spring 46 stretches, the piston plate 45 can use the action of air to inject air into the interior of the telescopic rod 33 through the pipeline.

[0036] In summary, when the rotating cylinder 43 rises, the rotating cylinder 43 will drive the rotating rod 42 to rise and fall synchronously. During this process, the cooperation of the piston rod 44, the piston plate 45 and the first spring 46 can effectively inject air into the interior of the piston cylinder 32. Such a setting enables the device to automatically inject air into the interior of the telescopic rod 33 according to the actual thickness of the boxed finished knitted textiles. This innovative air pressure injection mechanism not only improves the classification function of the adjustment component for boxed finished knitted textiles of different thicknesses, but also significantly improves the response speed and processing accuracy of the equipment to product specification changes.

[0037] Example 3, refer to Figure 3 and Figure 6 , which is the third embodiment of the present invention. Different from the previous embodiment, it solves the problem of pushing the boxed finished knitted products.

[0038] The infrared induction module 47 is provided with a pushing component 5 at the bottom directly below the frame 38. The pushing component 5 includes a motor 52. The output end of the motor 52 is installed with a rotating rod 53 through a coupling. An auxiliary wheel 55 is arranged outside the rotating rod 53. The pushing component 5 is a structure for pushing the boxed finished knitted textiles, and the motor 52 is fixed inside the frame 38 by bolts, and the motor 52 is connected to the rotating rod 53 through the action of the coupling. When the motor 52 is started, the motor 52 will drive the rotating rod 53 to rotate. During the rotation of the rotating rod 53, due to the threaded connection between the rotating rod 53 and the auxiliary wheel 55, the auxiliary wheel 55 can rotate with the rotation of the rotating rod 53.

[0039] The pushing component 5 further includes a movable seat 54. An auxiliary rod 56 is movably installed inside the movable seat 54. The top of the auxiliary rod 56 is slidably connected with a connecting rod 57. Since the auxiliary rod 56 is movably connected to the movable seat 54, when the auxiliary rod 56 rotates, the auxiliary rod 56 will rotate inside the movable seat 54.

[0040] A transmission wheel 51 is arranged at one end of the connecting rod 57 and the rotating rod 53. A transmission belt is sleeved on the outer wall of the transmission wheel 51. The connecting rod 57 and the rotating rod 53 are fixedly connected to the transmission wheel 51. During the rotation of the connecting rod 57, the connecting rod 57 will drive the transmission wheel 51 to rotate.

[0041] An outer side of the auxiliary rod 56 is provided with a connecting seat 58. One side of the bottom outer wall of the connecting seat 58 is provided with a second spring 59. When the auxiliary rod 56 moves, the auxiliary rod 56 will drive the connecting seat 58 to move. During the movement of the connecting seat 58, the connecting seat 58 will stretch the second spring 59 or utilize the effect of the second spring 59 to enable the auxiliary rod 56 to effectively perform a reset process.

[0042] When in use, first start the motor 52. When the motor 52 operates, the motor 52 can drive the rotating rod 53 to rotate by means of the coupling. During the rotation of the rotating rod 53, the rotating rod 53 can drive the auxiliary wheel 55 on its outer wall to rotate. The auxiliary wheel 55 can drive the connecting seat 58 to move by means of the fitting with the auxiliary rod 56.

[0043] In summary, when the motor 52 is operating, the motor 52 can drive the auxiliary wheel 55 and the auxiliary rod 56 to move by means of the rotating rod 53. The auxiliary rod 56 can drive the connecting seat 58 to move, so that the connecting seat 58 can stretch or squeeze the second spring 59. Such a setting enables the device to effectively push the boxed finished knitted textiles, thereby improving the effective pushing of the boxed finished knitted textiles by the device.

[0044] Example 4, refer to Figure 1 、 Figure 3 and Figure 5 This is the third embodiment of the present invention. Different from the previous embodiment, it solves the problem of adjusting according to the width of the boxed finished knitted textiles.

[0045] The top of the connecting seat 58 is provided with an expansion component 6. The expansion component 6 includes a screw rod 61. The screw rod 61 is movably installed inside the connecting seat 58 through a bearing. An outer side of the screw rod 61 is provided with a connecting block 62. The top of the connecting block 62 is provided with a connecting plate 63. The screw rod 61 is movably installed inside the connecting seat 58 through a bearing, and one end of the screw rod 61 extends to the outside of the connecting seat 58. The connection between the connecting block 62 and the connecting plate 63 enables the connecting block 62 to drive the connecting plate 63 to move when moving, and the height of the connecting plate 63 is lower than the height of the thinnest boxed finished knitted textiles.

[0046] The expansion component 6 further includes sliding grooves 64 opened on both sides inside the frame 38. A third spring 65 is arranged inside the sliding grooves 64. One end of the third spring 65 is provided with a limiting frame 66. The limiting frame 66 is slidably connected to the inside of the sliding grooves 64. One end of the third spring 65 is connected to the limiting frame 66, and the other end of the third spring 65 is connected to the sliding grooves 64.

[0047] During use, when the screw rod 61 is rotated, the screw rod 61 can drive the connecting block 62 to move by means of the threaded connection with the connecting block 62. During the movement of the connecting plate 63, the connecting plate 63 will move. And when the boxed finished knitted textiles are inserted into the interior of the frame 38, it will drive the limiting frame 66 to move. When the limiting frame 66 moves, the limiting frame 66 will stretch the third spring 65, so that the longer boxed finished knitted textiles can be effectively limited by the action of the third spring 65.

[0048] In summary, by providing the connecting plate 63, when the operator rotates the screw rod 61, the threaded engagement between the screw rod and the connecting block 62 drives the connecting plate 63 to move linearly, enabling the device to automatically adapt and adjust the optimal position of the connecting plate 63 according to the actual length parameters of the boxed finished knitted textiles. This not only ensures the precise positioning of the equipment for products of different specifications but also significantly improves the compatibility of the production line. And through the coordinated cooperation of the third spring 65 and the limiting frame 66, while ensuring the positioning accuracy of the product, the device realizes the reliable accommodation of knitted textiles of different length specifications, further strengthening the operation adaptability and function extensibility of the whole machine.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
