Description

Technical Field

[0001] This utility model belongs to the field of thin film production technology, and in particular relates to a roller replacement device. Background Technology

[0002] In the film production process, the film is usually wound onto a roller. When the film on the roller reaches its maximum capacity, the roller needs to be replaced. Since the roller is heavy at this time, it is usually replaced by hoisting. However, the cables used for hoisting can easily cause the roller to sway horizontally during the hoisting process. A structure that can avoid horizontal swaying of the roller during hoisting is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a roller replacement device that solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a roller replacement device, comprising a slider, a positioning assembly, and a lifting assembly. Two sliders are symmetrically slidably arranged on both sides of a frame, and a roller is horizontally arranged below the sliders. Both ends of the roller are inserted into sleeves, and the ends of the roller are attached to the inner wall of the sleeves. The two sleeves are respectively fixedly connected to their corresponding positioning plates, and the two positioning plates are respectively arranged below their corresponding sliders. The positioning assembly is used to make the two positioning plates slide towards each other. The lifting assembly is used to make the roller rise vertically.

[0005] Beneficial effects

[0006] This utility model provides a roller replacement device, which has the following advantages compared with the prior art:

[0007] 1. The user places the roller between the two positioning plates and makes the roller and sleeve coaxial. The user slides the two positioning plates toward each other using the positioning assembly. At this time, the sleeve begins to gradually cover the end of the roller. Since the end of the roller is in contact with the inner wall of the sleeve, the roller can be effectively limited after the end of the roller is inserted into the sleeve, preventing the roller from swaying horizontally. Then the user can start to lift the roller using the lifting assembly. During this process, the positioning plates rise synchronously with the roller, so that the sleeve limits the roller throughout the process, thereby preventing the roller from swaying horizontally during the lifting process.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 According to one embodiment of the present invention, a roller replacement device includes a slider 201, a positioning component, and a lifting component. Two sliders 201 are symmetrically slidably arranged on both sides of a frame 101, and a roller 203 is horizontally arranged below the sliders 201. The two ends of the roller 203 are inserted into sleeves 204, and the ends of the roller 203 are attached to the inner wall of the sleeves 204. The two sleeves 204 are respectively fixedly connected to their corresponding positioning plates 202, and the two positioning plates 202 are respectively arranged below their corresponding sliders 201.

[0016] The positioning component is used to make the two positioning plates 202 slide towards each other; the lifting component is used to make the roller 203 rise vertically.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific sleeve 204 described in the above embodiments. For example, the inner wall of the sleeve 204 may be provided with a soft anti-slip rubber ring. The purpose of this arrangement is to facilitate the tight fit between the end of the roller 203 and the sleeve 204 and to prevent slippage.

[0018] In the above embodiment, the user pushes the roller 203 between the two positioning plates 202 and makes the roller 203 coaxial with the sleeve 204. The user slides the two positioning plates 202 toward each other through the positioning component. At this time, the sleeve 204 begins to gradually cover the end of the roller 203. Since the end of the roller 203 is in contact with the inner wall of the sleeve 204, the sleeve 204 can effectively limit the roller 203 after the end of the roller 203 is inserted into it, thus preventing the roller 203 from swaying horizontally. Then the user can start to lift the roller 203 through the lifting component. During this process, the positioning plate 202 rises synchronously with the roller 203, so that the sleeve 204 limits the roller 203 throughout the process, thereby preventing the roller 203 from swaying horizontally during the lifting process.

[0019] Specifically, the positioning component includes a frame 208 and a guide component. The positioning plate 202 is slidably disposed on the frame 208 and slides horizontally linearly on the frame 208. A rack 205 is provided on the upper side of the inner wall of the positioning plate 202, and a gear 206 is meshed and connected below the rack 205.

[0020] The guide component is used to guide the frame 208 to slide vertically below the slider 201.

[0021] In the above embodiment, since the rack 205 is meshed with the gear 206 above it, when the gear 206 rotates, the rack 205 can drive the sleeve 204 fixedly connected to it to perform linear horizontal movement. That is, at this time, the two sleeves 204 start to move towards each other, thereby starting to limit the roller shaft 203.

[0022] Specifically, the gear 206 is fixedly connected to the output shaft of the motor 207, and the motor 207 is fixedly connected to the frame 208, and the motor 207 has a self-locking effect.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor 207 described in the above embodiments. For example, the motor 207 has a self-locking effect, which can increase the limiting effect on the sleeve 204, thereby enabling it to stably contact the roller 203.

[0024] In the above embodiment, since the gear 206 is fixedly connected to the output shaft of the motor 207, the gear 206 can rotate at a constant speed when the motor 207 starts. Furthermore, since the motor 207 has a self-locking effect, it can effectively increase the limiting effect on the gear 206.

[0025] Specifically, the guide assembly includes a connecting rod 209, the frame 208 is slidably disposed on the connecting rod 209, and a spring 301 is sleeved on the connecting rod 209, with both ends of the spring 301 being fixedly connected to the frame 208 and the connecting rod 209 respectively.

[0026] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific connecting rod 209 described in the above embodiments. For example, the connecting rod 209 is provided with a damping rubber strip. The purpose of this setting is to facilitate the smooth lifting and lowering of the frame 208.

[0027] In the above embodiment, since the frame 208 is vertically slidably mounted on the connecting rod 209, the frame 208 can be driven to rise synchronously during the process of the roller 203 being lifted by the lifting assembly. That is, at this time, the frame 208 begins to slide upward along the length direction of the connecting rod 209. Under the limiting action of the connecting rod 209, the horizontal movement of the connecting rod 209 can be effectively prevented. At the same time, during the upward sliding of the frame 208, the spring 301 fixedly connected to it can be stretched, causing it to undergo elastic deformation, so that after the frame 208 stops rising, it can be pulled back to its original position by the spring 301.

[0028] Specifically, the lifting assembly includes a cable 303 and a hook 304. Both ends of the roller 203 are hung in the hook 304, and the hook 304 is fixedly connected to the bottom end of the cable 303. The upper end of the cable 303 is fixedly connected to the outer surface of the drum 302, and the drum 302 is rotatably disposed in the slider 201.

[0029] The adjustment component is used to horizontally adjust the position of the roller 203.

[0030] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific roller 203 described in the above embodiments. For example, the part of the roller 203 that contacts the hook 304 is provided with a groove. The purpose of this setting is to increase the limiting effect on the hook 304 and prevent the hook 304 from sliding on it during hoisting.

[0031] Specifically, one end of the cable 303 is fixedly connected to the output shaft of the motor A305, and the motor A305 is fixedly connected to the outer wall of the slider 201.

[0032] In the above embodiment, the user can start the motor A305, which causes the drum 302 fixedly connected to its output shaft to rotate synchronously. At this time, the drum 302 begins to wind the cable 303 fixedly connected to it, so that the cable 303 uniformly lifts the roller 203 suspended on the hook 304 at a uniform speed.

[0033] Specifically, the adjustment assembly includes two lead screws 306, which are horizontally arranged on both sides of the top of the frame 101 and rotatably connected to the frame 101. Two sliders 201 are threadedly connected to the lead screws 306, and one end of the lead screw 306 is fixedly connected to the output shaft of the motor B307. The motor B307 is fixedly connected to the side wall of the frame 101.

[0034] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motors A305 and B307 described in the above embodiments. For example, both motors A305 and B307 have a self-locking effect.

[0035] In the above embodiment, the user can start the motor B307 to make the lead screw 306 rotate at a constant speed. At this time, the slider 201 threaded on it begins to slide laterally along the connection between it and the frame 101, thereby adjusting the position of the roller 203 suspended below it.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0038] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0039] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0040] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0041] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
