Description

Technical Field

[0001] This application relates to the field of plastic packaging processing equipment technology, specifically to a semi-finished film hanging rack for plastic packaging processing. Background Technology

[0002] In the plastic packaging processing, the winding of semi-finished film is crucial. Traditional semi-finished film hanging racks have many drawbacks. Their structural design may lead to insufficient overall stability, causing swaying during winding and affecting the flatness and quality of the roll. These racks are usually difficult to move or extremely inconvenient to move, limiting their flexible application in different production sites or processes. The installation and removal of the winding rollers often require a lot of time and effort, making the operation complex and significantly reducing production efficiency. Traditional hanging racks lack effective adjustment mechanisms for different specifications of winding rollers, making them unable to adapt quickly. This not only limits the versatility of the equipment but may also affect the winding effect due to poor compatibility. The height adjustment of the winding rollers is not precise enough to meet the different requirements of different thicknesses or materials of plastic packaging films for winding height, which can easily lead to uneven film tension, causing problems such as wrinkles and breakage during winding.

[0003] Therefore, in order to improve the overall efficiency and product quality of plastic packaging processing, there is an urgent need for a semi-finished film suspension frame for plastic packaging processing that can solve the above-mentioned problems and achieve convenient operation, precise adjustment and stable drive of the winding roller. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the issues of difficulty in installing, adjusting the height and lateral position of the winding roller, and the instability of the drive rotation affecting winding efficiency and quality during the winding of semi-finished film in plastic packaging processing.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a semi-finished film suspension frame for plastic packaging processing, comprising a support assembly, a suspension assembly, a lifting assembly, and a drive assembly. The support assembly includes two support frames and two stabilizing rods, and the two stabilizing rods are tightly connected in the through holes of the two support frames.

[0006] The suspension assembly includes a suspension rod and a drive rod, the suspension rod being inserted into and supporting one end of the take-up roller, and the drive rod sliding horizontally and moving vertically on the support frame.

[0007] The lifting assembly includes an inner slider, an extension plate, and a limiting rod. The inner slider slides on a vertical groove of the support frame. The inner slider is provided with a horizontal groove for the drive rod to slide. Two extension plates are fixedly installed at one end of the inner slider. The support frame is provided with multiple through holes that match the limiting rod. The extension plates are provided with through holes that correspond to the support frame. The vertical height of the lifting assembly and the drive rod is fixed by inserting the limiting rod into the through holes of the extension plates and the support frame.

[0008] The drive assembly includes a mounting plate, a toothed ring, limiting wheels, and a drive chain. The mounting plate is fixedly mounted on the inner slider at the end opposite to the extension plate. The toothed ring is rotatably mounted on the mounting plate. The through-hole axes of the mounting plate, the toothed ring, and the inner slider coincide. Multiple limiting wheels are rotatably arranged on the mounting plate to squeeze and limit the drive chain. The drive chain meshes with the toothed ring.

[0009] The suspension assembly includes a telescopic rod, a top mounting rod, and a threaded rod. There are two telescopic rods, each rotatably connected to both ends of the drive rod. Each telescopic rod has a top mounting rod at the end furthest from the drive rod. The two ends of the threaded rod are rotatably connected to the top mounting rod. The top mounting rod has threaded grooves, which drive the threaded rod to move laterally, thereby causing the drive rod and suspension rod to move laterally.

[0010] The suspension assembly includes a secondary gear with a rotating cylinder mounted on it. The rotating cylinder is rotatably connected to the support frame and fitted onto the threaded rod. The rotating cylinder has threads that match the threaded groove of the threaded rod.

[0011] The suspension assembly includes two side slide rods, each with its two ends fixedly connected to two top mounting rods. The side slide rods slide on the through holes of the support frame, and the two side slide rods are located on both sides of the threaded rod.

[0012] The drive assembly includes a lower gear and an upper gear, which are located on the upper and lower sides of the gear ring, respectively, and support and mesh with the drive chain.

[0013] The toothed ring is provided with a slider, and the drive rod is provided with a groove, and the slider of the toothed ring matches the groove of the drive rod.

[0014] The technical solution provided in this application has the following advantages compared with the prior art:

[0015] 1: This application achieves stable support and flexible movement of the suspension frame by setting a support component consisting of a support frame, a stabilizer bar, and a movable frame with casters. This solves the problem of poor stability of the suspension frame and difficulty in conveniently moving it to different work locations, and improves the ease of use of the suspension frame in different production scenarios.

[0016] 2: This application achieves rapid replacement of the take-up roller and precise adjustment of its lateral position through the design of the telescopic rod, top mounting rod, threaded rod, side sliding rod, and displacement motor in the suspension assembly in conjunction with the main and auxiliary gears. This solves the problems of difficulty in adapting take-up rollers to different specifications and cumbersome replacement operations, and improves the equipment's adaptability to various take-up roller specifications and its operating efficiency.

[0017] 3: This application achieves precise adjustment and stable rotation of the take-up roller height by coordinating the slider, extension plate, limit rod, ring frame and indicator block in the lifting assembly, as well as the mutual cooperation of the drive assembly gear ring, drive chain, upper and lower gears, etc., which solves the problems of inconvenient adjustment of take-up roller height and unstable rotation that easily cause winding quality problems, and improves the accuracy of winding operation and winding quality.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] like Figures 1 to 8 As shown, a semi-finished film hanging rack for plastic packaging processing includes a support assembly 100, a hanging assembly 200, a lifting assembly 300, and a driving assembly 400. The support assembly 100 includes two support frames 102 and two stabilizing rods 103, which are tightly connected to each other in the through holes of the two support frames 102.

[0030] Specifically, two support frames 102 are arranged opposite each other, and are supported at the lower end by two stabilizing rods 103 to stabilize the two support frames 102 and prevent swaying. The support assembly 100 includes 11, with a movable frame 101 fixedly installed at the bottom of the support frame 102. The movable frame 101 is equipped with casters, which are used to move the support frame 102 and its related components, as well as the take-up roller supported by the two support frames 102.

[0031] The suspension assembly 200 includes a suspension rod 209 and a drive rod 202. The suspension rod 209 is inserted into and supports one end of the take-up roller, and the drive rod 202 slides horizontally and moves vertically on the support frame 102.

[0032] Specifically, the suspension rod 209 includes a support shaft and a protective ring. The support shaft is used to insert into the inner hole of the take-up roller, and the protective ring blocks and limits the take-up roller. The take-up roller is fixed by the relative movement of the suspension rods 209 on the two support frames 102. The take-up roller is tightly connected to the protective ring of the suspension rod 209, which facilitates the subsequent rotation of the suspension rod 209 and the take-up roller by the drive rod 202 to wind up the semi-finished film.

[0033] The position of the suspension rod 209 can be adjusted by the horizontal sliding of the drive rod 202 on the support frame 102, which facilitates the replacement of the semi-finished film take-up roller and can be adjusted according to different specifications of take-up roller, thus adapting to a variety of application scenarios.

[0034] The lifting assembly 300 includes an inner slider 301, an extension plate 302, and a limiting rod 304. The inner slider 301 slides on a vertical groove in the support frame 102. The inner slider 301 is provided with a horizontal groove for the drive rod 202 to slide. Two extension plates 302 are fixedly installed at one end of the inner slider 301. The support frame 102 is provided with multiple through holes that match the limiting rod 304. The extension plate 302 is provided with through holes that correspond to the support frame 102. The vertical height of the lifting assembly 300 and the drive rod 202 is fixed by inserting the limiting rod 304 into the through holes of the extension plate 302 and the support frame 102.

[0035] Specifically, the lifting assembly 300 includes a ring frame 303 and an indicator block 305. The ring frame 303 is provided with four limiting rods 304. Each pair of limiting rods 304 forms a group, and each group of limiting rods 304 corresponds to an extension plate 302. That is, an extension plate 302 is provided with two through holes. The two limiting rods 304 are inserted into the two through holes on the extension plate 302 and into two adjacent through holes on the same side of the support frame 102. Both sides of the inner slider 301 are connected by two limiting rods 304 and through holes to avoid the shaking that is easily caused by a single limiting rod 304, thereby reducing shaking and stabilizing the position of the inner slider 301.

[0036] The ring frame 303 is fixedly connected to four limiting rods 304, so the operator only needs to control the movement of the ring frame 303 to control the four limiting rods 304 to enter and exit the through holes of the extension plate 302 and the support frame 102, and control the lifting assembly 300 to slide vertically on the vertical slide groove of the support frame 102, thereby adjusting the height of the drive rod 202 and the winding roller.

[0037] Each extension plate 302 has an indicator block 305 at its upper and lower ends. The indicator block 305 has a semi-circular notch that matches the through hole specification of the support frame 102. The distance between the semi-circular notch and the through hole of the extension plate 302 is the same as the distance between adjacent through holes on the support frame 102. Thus, when adjusting the height of the lifting assembly 300, the operator can determine whether the lifting assembly 300 has moved into place by checking whether the semi-circular notch on the indicator block 305 corresponds to the through hole of the support frame 102. When pushing the ring frame 303, the operator can also check whether the limiting rod 304 can be accurately inserted into the through hole of the support frame 102, thereby reducing the difficulty of operation and saving adjustment time.

[0038] The drive assembly 400 includes a mounting plate 401, a toothed ring 402, a limiting wheel 403, and a drive chain 404. The mounting plate 401 is fixedly mounted on the inner slider 301 at the end opposite to the extension plate 302. The toothed ring 402 is rotatably mounted on the mounting plate 401. The axes of the through holes of the mounting plate 401, the toothed ring 402, and the inner slider 301 coincide. Multiple limiting wheels 403 are rotatably arranged on the mounting plate 401. The limiting wheels 403 squeeze and limit the drive chain 404, and the drive chain 404 meshes with the toothed ring 402.

[0039] Specifically, such as Figure 8 As shown, the four limiting wheels 403 on the mounting plate 401 are located at the four corners of the toothed ring 402, jointly pressing against both sides of the drive chain 404. This keeps the drive chain 404 close to the toothed ring 402, thus preventing the drive chain 404 from disengaging when the toothed ring 402 rotates. Without support, the drive chain 404 would disengage, lose driving force, and be unable to control the rotation of the drive rod 202, suspension rod 209, and take-up roller. When the toothed ring 402 rotates, the two sides of the drive chain 404 mesh, causing the drive chain 404 to move in the same direction of rotation as the toothed ring 402. This, in turn, drives the drive rod 202 to rotate through the cooperation of the slider on the toothed ring 402 and the groove of the drive rod 202.

[0040] like Figure 5 and Figure 6 As shown, the suspension assembly 200 includes a telescopic rod 201, a top mounting rod 203, and a threaded rod 208. There are two telescopic rods 201, which are rotatably connected to both ends of the drive rod 202. Each telescopic rod 201 has a top mounting rod 203 at the end away from the drive rod 202. The two ends of the threaded rod 208 are rotatably connected to the top mounting rod 203. The top mounting rod 203 is provided with a threaded groove, which drives the threaded rod 208 to move laterally, thereby driving the drive rod 202 and the suspension rod 209 to move laterally.

[0041] Specifically, the telescopic structure of the telescopic rod 201 accommodates the lifting and lowering movement of the drive rod 202 in the vertical slide groove of the support frame 102. When the threaded rod 208 is driven to move laterally, the toothed ring 402 drives both ends of the drive rod 202 to move laterally. As the drive rod 202 moves, it causes the suspension rod 209 to move accordingly. Thus, by controlling the movement of the drive rods 202 on both sides of the support frame 102 by a corresponding distance, the replacement of the take-up roller and the overall horizontal movement are achieved.

[0042] like Figure 5 and Figure 6As shown, the suspension assembly 200 includes a secondary gear 207, on which a rotating cylinder is provided. The rotating cylinder is rotatably connected to the support frame 102 and is sleeved on the threaded rod 208. The rotating cylinder is provided with threads that match the threaded groove of the threaded rod 208.

[0043] Specifically, the suspension assembly 200 includes a displacement motor 205 and a main gear 206. The displacement motor 205 is fixedly installed on the top of the support frame 102, and the output end of the displacement motor 205 is fixedly connected to the main gear 206. The main gear 206 meshes with the secondary gear 207, so that the operator can control the displacement motor 205 to start through the display screen and electronic control system on the support frame 102, driving the main gear 206 and the secondary gear 207 to rotate. Then, the rotating drum of the secondary gear 207 drives the threaded rod 208 to move laterally on the support frame 102 through threaded engagement. The threaded rod 208 then pulls and pushes the top mounting rods 203 on both sides of the support frame 102 to move. The top mounting rods 203 drive the drive rod 202 to move through the telescopic rod 201, thereby realizing the adjustment of the suspension rod 209.

[0044] like Figure 5 and Figure 6 As shown, the suspension assembly 200 includes two side slide rods 204. The two ends of the side slide rods 204 are fixedly connected to two top mounting rods 203 respectively. The side slide rods 204 slide on the through hole of the support frame 102. The two side slide rods 204 are located on both sides of the threaded rod 208.

[0045] Specifically, the movement of the top mounting rod 203 and the threaded rod 208 is supported by two side sliding rods 204, which prevents excessive friction between the threaded rod 208 and the support frame 102 from affecting the lateral movement of the threaded rod 208. In addition, the side sliding rods 204 on both sides of the threaded rod 208 also support the top mounting rod 203, preventing the top mounting rod 203 and the telescopic rod 201 from swaying, and stabilizing the winding drum supported by the suspension rod 209.

[0046] like Figure 2 and Figure 3 As shown, the drive assembly 400 includes a lower gear 405 and an upper gear 408, which are located on the upper and lower sides of the gear ring 402, respectively, and support and mesh with the drive chain 404.

[0047] Specifically, the upper gear 408 is fixedly mounted on the fixed plate 407, which in turn is fixedly mounted on the support frame 102. The upper gear 408 and the gear ring 402 stretch the drive chain 404, keeping it taut, thus ensuring the drive chain 404 drives the gear ring 402 and allows the take-up roller to rotate stably. The support frame 102 has a groove, on which a drive motor 406 is fixedly mounted. The output end of the drive motor 406 is fixedly connected to the lower gear 405. The operator controls the drive motor 406 to start via the display screen and electrical control system of the support frame 102. The drive motor 406 drives the lower gear 405 to rotate, and the lower gear 405 drives the drive chain 404 through meshing. The drive chain 404 then drives the gear ring 402 and the upper gear 408 to rotate.

[0048] like Figure 3 and Figure 6 As shown, a slider is provided on the toothed ring 402, and a groove is provided on the drive rod 202. The slider of the toothed ring 402 matches the groove of the drive rod 202.

[0049] Specifically, through the slider of the toothed ring 402 and the groove of the drive rod 202, when the toothed ring 402 is driven to rotate, it can drive the drive rod 202 to rotate on the mounting plate 401 and the inner slider 301, and drive the suspension rod 209 and the take-up roller to rotate.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
