Description

Technical Field

[0001] The utility model belongs to the technical field of winding and unwinding equipment, and relates to a consumable material rack with integrated winding and unwinding. Background Art

[0002] In automated processing, continuous and stable material delivery is crucial for smooth production. Therefore, many steps and processes require a continuous flow of material through unwinding and rewinding mechanisms. The unwinding mechanism smoothly releases the material from the roll, while the rewinding mechanism rewinds the processed material or peeled parts to maintain continuous production line operation.

[0003] However, in existing technologies, although the consumables can be released from the unwinding mechanism by pulling the consumables through the conveyor roller, a separate motor is still required to drive the rewinding mechanism for rewinding. This means that existing rewinding and unwinding racks require at least one motor, increasing the overall cost of the equipment. More importantly, if these existing racks are not controlled by software, the rewinding and unwinding speeds will be inconsistent. This inconsistent speed will prevent the coil from being tightened, thus leaving room for improvement. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a consumables rack with an integrated retractable and unreeling structure.

[0008] The unwinding reel is aligned with the winding reel, the two first wheel-shaped end plates are respectively aligned with the two second wheel-shaped end plates, and at least one group of aligned first wheel-shaped end plates is linked to the second wheel-shaped end plates. When the unwinding shaft rotates, the winding shaft is driven to rotate through the linked first wheel-shaped end plates and the second wheel-shaped end plates.

[0009] Preferably, the outer edge surface of the first wheel-shaped end plate is provided with a first gear portion, the outer edge surface of the second wheel-shaped end plate is provided with a second gear portion, and the first gear portion of the first wheel-shaped end plate is meshed with the second gear portion of the aligned second wheel-shaped end plate.

[0010] Preferably, a transmission belt is sleeved on the first wheel-shaped end plate and the second wheel-shaped end plate, and the first wheel-shaped end plate and the second wheel-shaped end plate are linked to each other through the transmission belt.

[0011] Preferably, the first wheel-shaped end plate and the second wheel-shaped end plate are configured to have the same linear speed.

[0012] Preferably, the unwinding shaft and the coil to be released are arranged to be circumferentially fixedly connected, and the winding shaft and the coil to be wound are arranged to be slidingly connected; or the unwinding shaft and the coil to be released are arranged to be slidingly connected, and the winding shaft and the coil to be wound are arranged to be circumferentially fixedly connected.

[0013] Preferably, it further comprises a first support frame and a second support frame, the unwinding reel is rotatably mounted on the first support frame, and the winding reel is rotatably mounted on the second support frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The winding reel and the unwinding reel are linked to form an integrated winding and unwinding structure.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1-4 As shown, a reel-and-roll integrated consumables rack includes: an unwinding reel 100, the unwinding reel 100 includes an unwinding shaft 110 and two first wheel-shaped end plates 120, the two first wheel-shaped end plates 120 are arranged in parallel and are respectively located at both ends of the unwinding shaft 110, and the two first wheel-shaped end plates 120 are circumferentially fixed to the unwinding shaft 110; a winding reel 200, the winding reel 200 includes a winding shaft 210 and two second wheel-shaped end plates 220, the two second wheel-shaped end plates 220 are arranged in parallel The two second wheel-shaped end plates 220 are arranged and located at both ends of the winding shaft 210, and are circumferentially fixed to the winding shaft 210; the unwinding reel 100 is aligned with the winding reel 200, and the two first wheel-shaped end plates 120 are respectively aligned with the two second wheel-shaped end plates 220, and at least one group of aligned first wheel-shaped end plates 120 is linked to the second wheel-shaped end plates 220. When the unwinding shaft 110 rotates, the winding shaft 210 is driven to rotate through the linked first wheel-shaped end plates 120 and the second wheel-shaped end plates 220.

[0026] The consumables rack is designed to handle roll materials (such as paper, film, and fabric) in automated or semi-automated equipment. It is particularly suitable for automatically supplying, rewinding, and stripping consumables during radionuclide application preparation. The core of this consumables rack is the synchronization of unwinding and rewinding functions through mechanical linkage, improving production efficiency and the smoothness of the automated preparation process.

[0027] The unwinding reel 100 is used to hold the rolled material to be processed and is primarily composed of an unwinding shaft 110 and two first wheel-shaped end plates 120. The first wheel-shaped end plates 120 are similar to a disc-shaped structure, mounted on either end of the unwinding shaft 110 and circumferentially fixed to the unwinding shaft 110. When the unwinding shaft 110 rotates, the two first wheel-shaped end plates 120 rotate with the unwinding shaft 110. The winding reel 200 is used to wind up consumables or materials stripped from consumables. Its structure is similar to that of the unwinding reel 100, consisting of a winding shaft 210 and two second wheel-shaped end plates 220, which rotate with the winding shaft 210.

[0028] The first wheel-shaped end plate 120 and the second wheel-shaped end plate 220 located on the same side are aligned with each other and linked together, so when the unwinding shaft 110 rotates to release the consumables, the reeling shaft 210 can be driven to rotate at the same time through this linkage mechanism to reel in the consumables or the peeled materials.

[0029] It should be noted here that: in one embodiment, only one first wheel-shaped end plate 120 is linked to the corresponding second wheel-shaped end plate 220; in another embodiment, the two first wheel-shaped end plates 120 are linked to the two second wheel-shaped end plates 220 respectively.

[0030] like Figure 1 、 Figure 2 、 Figure 4 As shown, in the application of this consumables rack on the equipment, the consumables roll is installed on the unwinding shaft 110, and the consumables are drawn out from the unwinding shaft 110 and pass through the conveyor roller. The reel 210 is wound with the consumables that have passed through the conveyor roller or the film material peeled off from the consumables. The conveyor roller provides power for the movement of the consumables. When the consumables are subjected to the traction force of the conveyor roller, the unwinding shaft 110 is forced to rotate. At this time, the first wheel-shaped end plate 120 on the unwinding shaft 110 drives the second wheel-shaped end plate 220 to rotate through a linkage mechanism, thereby causing the reel 210 to rotate synchronously. In this way, the unwinding shaft 110 and the reel 210 rotate together without being directly driven by the motor, realizing the motor-free design of the consumables rack.

[0031] The winding reel 200 and the unwinding reel 100 are linked and connected to form an integrated winding and unwinding structure. In actual use, the consumables can be pulled forward by the conveyor roller, and the unwinding reel 100 and the unwinding reel 100 automatically unwind and rewind. Therefore, the consumables rack theoretically does not need a motor, which reduces the cost of the consumables rack as well as the volume and weight of the equipment. In addition, there is no need for software control (because no motor is required, no complex control system or software algorithm is required) to ensure that the winding speed and the unwinding speed are consistent, thereby allowing the roll to be tightened during the winding and unwinding process.

[0032] Example 1:

[0033] like Figure 1-4 As shown, the outer edge surface of the first wheel-shaped end plate 120 is provided with a first gear portion 121, and the outer edge surface of the second wheel-shaped end plate 220 is provided with a second gear portion 221. The first gear portion 121 of the first wheel-shaped end plate 120 is meshed with the second gear portion 221 of the aligned second wheel-shaped end plate 220.

[0034] Example 1 realizes linkage connection through gear meshing transmission. The first gear part 121 is a gear structure composed of a series of evenly distributed teeth, and the second gear part 221 is also a gear structure composed of a series of evenly distributed teeth. The torque of the unwinding shaft 110 can be transmitted to the winding shaft 210 through the gear meshing transmission mechanism, thereby realizing linkage connection between the two.

[0035] Example 2:

[0036] A transmission belt is provided on the first wheel-shaped end plate 120 and the second wheel-shaped end plate 220, and the first wheel-shaped end plate 120 and the second wheel-shaped end plate 220 are linked together by the transmission belt. In the second embodiment, the unwinding shaft 110 and the reeling shaft 210 are linked together by the transmission belt.

[0037] like Figure 1-4 As shown, based on the above embodiment, the first wheel-shaped end plate 120 and the second wheel-shaped end plate 220 are set to have the same linear speed.

[0038] It should be noted that, regardless of whether the gear meshing or belt connection is adopted, the linear speeds of the first wheel-shaped end plate 120 and the second wheel-shaped end plate 220 are equal. In addition, the unwinding reel 100 is larger than the winding reel 200, and the winding becomes tighter and tighter during the entire operation.

[0039] Based on the above embodiment, the unwinding shaft 110 and the coil to be released are set to be circumferentially fixedly connected, and the winding shaft 210 and the coil to be wound are set to be slidingly connected; or the unwinding shaft 110 and the coil to be released are set to be slidingly connected, and the winding shaft 210 and the coil to be wound are set to be circumferentially fixedly connected.

[0040] It should be pointed out here that since the unwinding shaft 110 and the reeling shaft 210 are linked, that is, the angular velocity of unwinding and the angular velocity of rewinding are fixed, while the radius of the coil on the unwinding shaft 110 and the radius of the coil on the reeling shaft 210 are constantly changing, that is, as the consumables rack continues to operate, the radius of the coil on the unwinding shaft 110 gradually decreases, and the radius of the coil on the reeling shaft 210 gradually increases, and the constant angular velocity of unwinding and rewinding will cause the linear velocity of the coil release on the unwinding shaft 110 and the linear velocity of the coil rewinding on the reel 210 to change continuously. This change in the rewinding and unwinding linear velocity is caused by the operation of the consumables rack. To solve the above problems, the prior art usually uses an encoder in combination with a specific algorithm to control the speed of the unwinding motor and the rewinding motor, or a radius detection or linear velocity detection element in combination with a specific algorithm to control the speed of the unwinding motor and the rewinding motor, thereby changing the angular velocity of unwinding and rewinding. The above methods all require real-time calculation during operation.

[0041] The slipping structure used in this embodiment solves the problem of changes in the winding and unwinding linear speed under a fixed angular velocity, wherein the winding linear speed is always slightly greater than the unwinding linear speed, which means that the entire winding and unwinding process maintains a state of getting tighter and tighter, and the slipping design can prevent the consumables from breaking.

[0042] In the actual structure, a slippable connection is provided between the take-up shaft 210 and the coiled material. The number of teeth of the first gear portion 121 is greater than the number of teeth of the second gear portion 221. Due to the gear ratio between the two, the minimum linear speed of the coiled material on the take-up shaft 210 is always greater than the maximum linear speed of the coiled material on the unwinding shaft 110, ensuring that the take-up shaft 210 always remains taut.

[0043] like Figure 1 As shown, based on the above embodiment, it further includes a first support frame 300 and a second support frame 400, the unwinding reel 100 is rotatably mounted on the first support frame 300, and the winding reel 200 is rotatably mounted on the second support frame 400.

[0044] The first support frame 300 is used to install the unwinding reel 100, ensuring that the unwinding reel 100 can be rotatably installed thereon, and the second support frame 400 is used to install the winding reel 200, ensuring that the winding reel 200 can be rotatably installed thereon.

[0045] Based on the above embodiment, both ends of the unwinding shaft 110 have a first support end 111 passing through the first wheel-shaped end plate 120, and both ends of the winding shaft 210 have a second support end 211 passing through the second wheel-shaped end plate 220. The two first support ends 111 are supported on the first support frame 300, and the two second support ends 211 are supported on the second support frame 400.

[0046] By designing support ends at both ends of the unwinding shaft 110 and the reeling shaft 210 and installing them on the support frame, it can be ensured that the unwinding shaft 110 and the reeling shaft 210 can rotate freely during operation, thereby improving the stability and reliability of the structure.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0049] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0050] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
