Description

Technical Field

[0001] This invention belongs to the field of packaging technology, and specifically relates to a stretch film guiding device. Background Technology

[0002] Products need to be packaged before transportation to protect them. For example, injection molded parts produced in the workshop are usually placed on tooling carts. Before transportation, the tooling carts containing the injection molded parts are directly packaged to prevent contamination or damage. In existing technology, the tooling carts containing injection molded parts are generally wrapped manually. However, in actual production, packaging workers need to hold the stretch film for a long time to wrap the products, especially for larger products. Packaging workers need to bend over and hold or lift the protective film to complete the wrapping; sometimes, multiple workers are needed to work together to complete the packaging work, which reduces packaging efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a stretch film guiding device, which solves the technical problem of low packaging efficiency caused by the need for packaging workers to hold the stretch film for a long time in the prior art by placing the stretch film on a height-adjustable platform and guiding the stretch film through a guiding part.

[0004] To address the aforementioned problems, according to one aspect of this application, the present invention provides a stretch film guiding device, which includes a fixed frame, a transmission assembly, a platform, and an adjustment assembly. The transmission assembly is disposed on the fixed frame, one end of which is connected to the platform, and the other end of which is connected to the adjustment assembly. The platform is used to place the stretch film, and the adjustment assembly is slidably connected to the fixed frame to adjust the height of the platform. The fixed frame has a guide portion for guiding the stretch film.

[0005] In some embodiments, the guide portion is disposed near the stage and has a guide hole for the winding film to pass through, the guide hole extending along the height direction of the fixture.

[0006] In some embodiments, the stage includes a base, a first limiting member, and a second limiting member. One end of the first limiting member is fixed to the base, and the other end of the first limiting member faces the top of the mounting frame for mounting the stretch film. The second limiting member is connected to the bottom of the first limiting member for limiting the stretch film.

[0007] In some embodiments, the stretch film guiding device further includes a seated bearing, which is fixed to the base, and the inner ring of the seated bearing is connected to the bottom end of the first limiting member.

[0008] In some embodiments, the base has a threaded hole, the first limiting member is a screw, one end of the screw passes through the threaded hole and is located at the bottom of the fixing frame, and the other end of the screw is fixed to the stretch film for rotating the screw by rotating the stretch film.

[0009] In some embodiments, an arc-shaped guide structure is provided on the side of the guide portion opposite to the stage. The arc-shaped guide structure is located close to the guide hole and extends from the bottom of the guide hole to the top of the guide hole.

[0010] In some embodiments, the relationship between the height H1 of the adjusting component and the height H2 of the fixing frame satisfies H1:H2 = 0.5~1.

[0011] In some embodiments, the fixed frame is provided with a first guide rail and a second guide rail parallel to the first guide rail. Both the first guide rail and the second guide rail are arranged along the height direction of the fixed frame. The platform is slidably disposed on the first guide rail, and the adjustment component is slidably connected to the second guide rail.

[0012] In some embodiments, the adjustment component has an L-shaped structure and includes a first support member, a second support member, and at least two handles. The handles are connected between the first support member and the second support member, and are spaced apart along one end of the adjustment component to the other end.

[0013] In some embodiments, the transmission assembly includes a pulley block and a traction rope. The pulley block is fixed to a fixed frame, and the traction rope is wound around the pulley block. One end of the traction rope is connected to the platform, and the other end of the traction rope is connected to an adjustment assembly.

[0014] Furthermore, the bottom of the mounting bracket is equipped with a set of casters.

[0015] Compared with the prior art, the winding film guiding device of the present invention has at least the following beneficial effects:

[0016] This invention provides a stretch film guiding device for guiding stretch film during the packaging or collection of stretch film from products. For ease of understanding, the following description uses a packaging cart containing products as an example. A transmission component is mounted on a fixed frame to link the platform and the adjustment component, facilitating the adjustment of their positions. The platform holds the stretch film, allowing it to move during movement. The adjustment component is slidably connected to the fixed frame, allowing the platform to move and thus adjusting the height of the stretch film. Furthermore, a guide on the fixed frame guides the stretch film at different heights, improving packaging efficiency. This invention provides a stretch film guiding device that, by placing the stretch film on an adjustable-height platform and guiding it via the guide, solves the technical problem of low packaging efficiency caused by the need for packaging workers to hold the stretch film for extended periods in existing technologies, thereby improving efficiency while reducing production costs.

[0035] Example 1

[0036] This invention provides a winding film guiding device, see reference. Figures 1 to 12 The stretch film guiding device includes a fixed frame 1, a transmission assembly 2, a platform 3, and an adjustment assembly 4. The transmission assembly 2 is mounted on the fixed frame 1. One end of the transmission assembly 2 is connected to the platform 3, and the other end of the transmission assembly 2 is connected to the adjustment assembly 4. The platform 3 is used to place the stretch film. The adjustment assembly 4 is slidably connected to the fixed frame 1 to adjust the height of the platform 3. The fixed frame 1 has a guide part 11 for guiding the stretch film.

[0037] Specifically, the present invention provides a stretch film guiding device for guiding stretch film during the process of wrapping products or collecting stretch film from products. For ease of understanding, the following description uses a tooling cart 7 containing products as an example.

[0038] The transmission component 2 is mounted on the fixed frame 1 to link the platform 3 and the adjustment component 4, thereby facilitating the adjustment of the positions of the platform 3 and the adjustment component 4. The platform 3 is used to hold the stretch film so that the platform 3 moves the stretch film during movement. The adjustment component 4 is slidably connected to the fixed frame 1 so that the platform 3 moves by sliding the adjustment component 4, thereby adjusting the height of the stretch film to prevent packaging workers from holding heavy stretch film for extended periods. In addition, the guide part 11 on the fixed frame 1 guides the stretch film at different heights to improve packaging efficiency. The stretch film guiding device provided by this embodiment of the invention solves the technical problem of low packaging efficiency caused by packaging workers having to hold the stretch film for extended periods in the prior art by placing the stretch film on the adjustable height platform 3 and guiding the stretch film through the guide part 11, thereby improving efficiency while reducing production costs.

[0039] It should be noted that, in order to enable the stretch film guide device to move around the tooling carriage 7, and to reduce friction, the stretch film guide device provided in this embodiment can be placed on a trolley for use, or a moving component can be set at the bottom of the stretch film guide device.

[0040] The shape of the mounting bracket 1 can be a shell structure (not shown in the figure) or a frame structure (see reference). Figures 1 to 4 , Figure 11 by Figure 12 Alternatively, the support frame 1 can be another structure that provides support. The shape of the support frame 1 can be adjusted to suit the shape required by the packaged product. For ease of manufacturing and material saving, the support frame 1 is preferably a frame structure. The height of the support frame 1 can be adjusted to suit the needs of the packaged product.

[0041] The stage 3 is mounted on the frame 1 to place and secure the stretch film. The stage 3 can be a shell structure (not shown in the figure) or a frame structure (see reference). Figure 1 , Figure 3 , Figure 4 as well as Figures 9 to 12 When the platform 3 is a shell structure, it has a chamber for placing the stretch film, and an outlet communicating with the chamber. When the platform 3 is a frame structure, it has a limiting member for placing and fixing the stretch film to prevent it from falling during use. Furthermore, a drive mechanism can be installed on the platform 3 to drive the stretch film to rotate, thereby enabling the film to be exported and collected. For example, a stepper motor can be installed at the bottom of the platform 3, with the stretch film connected to the power output shaft of the stepper motor. The export and collection of the stretch film are achieved by rotating the stepper motor in both directions. The adjusting component 4 is slidably connected to the fixed frame 1, and is connected to the platform 3 via the transmission component 2 to adjust the height of the platform 3. The height of the adjusting component 4 can be adaptively adjusted according to the height of the worker, allowing the packaging personnel to move the adjusting component 4 to adjust the height of the platform 3 without bending over.

[0042] Transmission component 2 can be a pulley mechanism (see reference) Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 11 as well as Figure 12 Alternatively, an automatic lifting mechanism (not shown in the diagram) can be used. When the transmission component 2 is a pulley mechanism, the pulley assembly is fixed to the fixed frame 1. One end of the pulley assembly is connected to the platform 3, and the other end is connected to the adjustment component 4. Packaging personnel can adjust the height of the platform 3 by sliding the adjustment component 4. However, compared to the automatic lifting mechanism, the pulley mechanism and the gear and rack transmission mechanism have lower manufacturing and maintenance costs.

[0043] Furthermore, the guide portion 11 is used to guide the stretch film during the unwinding process, so as to wrap the stretch film relatively flat onto the tooling carriage 7 to improve packaging efficiency. In addition, the guide portion 11 also prevents the stretch film from contacting the edges of the fixing frame 1 and being damaged. It should be noted that the shape of the guide portion 11 can be matched with the shape of the fixing frame 1; for example, the height of the guide portion 11 can be greater than or equal to the height of the fixing frame 1, so that the guide portion 11 can guide the stretch film on the loading platform 3 at any height.

[0044] The guide part 11 can be a single component (not shown in the figure) or a guide part 11 composed of two components. For example, when the guide part 11 is a single component, the component can be a guide post. The side wall of the guide post has a curved structure. The curved structure can prevent the wrapping film from contacting the fixing frame 1, and the curved structure can also prevent itself from scratching the wrapping film.

[0045] When the guide section has 11 components, both components can be as follows: Figure 1 , Figure 3 as well as Figure 4 The two guide posts shown can both have their sidewalls used to guide the stretch film. Alternatively, multiple guide posts can be provided, staggered in the direction the stretch film is being discharged, allowing the film to pass through and preventing it from tangling during discharge.

[0046] In a preferred embodiment, the guide portion 11 is disposed near the stage 3, and the guide portion 11 has a guide hole for the wrapping film to pass through, the guide hole extending along the height direction of the fixing frame 1.

[0047] Specifically, the guide portion 11 is positioned close to the stage 3 to reduce the resistance of the stretch film and improve the winding effect. When the guide portion 11 consists of one or two components (not shown in the figure), it may also have guide holes extending along the height direction of the fixing frame 1 to guide stretch film of any height or size. For example, when the guide portion 11 is a single component, it may have guide holes; when the guide portion 11 consists of two components (see reference...), it may also have guide holes. Figure 1 , Figure 2 as well as Figure 3 These two components are spaced apart to form gaps or guide holes that can be used for the winding film to pass through.

[0048] In a specific embodiment, reference is made to... Figure 1 , Figure 3 , Figure 4 as well as Figure 9The platform 3 includes a base 31, a first limiting member 32 and a second limiting member 33. One end of the first limiting member 32 is fixed to the base 31, and the other end of the first limiting member 32 faces the top of the fixing frame 1 for mounting the stretch film. The second limiting member 33 is connected to the bottom of the first limiting member 32 for limiting the stretch film.

[0049] Specifically, the stretch film can be fitted onto the first limiting member 32, and the stretch film can rotate relative to the first limiting member 32. During the packaging process, the stretch film can be pulled to rotate on the first limiting member 32, thereby guiding the stretch film out. During the collection of the stretch film, a rotating member or motor (not shown in the figure) can be installed at the bottom or top of the first limiting member 32 to control the rotation of the first limiting member 32, thereby rewinding the stretch film onto the first limiting member 32 for recycling.

[0050] It should be noted that the first limiting member 32 can be a limiting post or other structure capable of rotation. The cross-section of the limiting post in its radial direction can be circular, polygonal, or other irregularly shaped. The second limiting member 33 can be a tray structure (not shown in the figure) or a limiting post (see reference). Figure 9 When the second limiting member 33 is a tray structure, the tray structure is placed on the base 31 and is parallel to the base 31. The first limiting member 32 is perpendicular to the plane where the tray structure is located. During installation, the wrapping film roll is sleeved on the first limiting member 32, and the bottom of the wrapping film roll is in contact with the tray structure. When the second limiting member 33 is a limiting post, the first limiting member 32 is set parallel to the sliding direction of the platform 3, and the limiting post is perpendicular to the extension direction of the first limiting member 32. During installation, the wrapping film roll is sleeved on the first limiting member 32, and the bottom of the wrapping film roll is in contact with the second limiting member 33.

[0051] In a specific embodiment, reference is made to... Figure 9 The stretch film guiding device also includes a seated bearing 5, which is fixed on the base 31, and the inner ring of the seated bearing 5 is connected to the bottom end of the first limiting member 32.

[0052] Specifically, when the stretch film roll is fitted onto the first limiting member 32, its own weight makes it difficult to rotate. Continuous tension on one end of the roll can easily tear it. A seated bearing 5 is provided between the first limiting member 32 and the base 31, allowing the first limiting member 32 to rotate relative to the base 31. This prevents the stretch film from being torn when it is difficult to rotate on its own, thus improving packaging efficiency. The seated bearing 5 includes a mounting base and a bearing. The mounting base has a groove, and the bearing is embedded in the groove. The inner ring of the bearing is connected to the first limiting member 32. The mounting base can be welded to the base 31, or it can be screwed to the base 31.

[0053] It should be noted that the first limiting member 32 can also restrict the rotation of the wrapping film roll. By pulling the other end of the wrapping film roll, the bearing 5 with the seat can be rotated, thereby unloading the wrapping film.

[0054] In a specific embodiment, reference is made to... Figure 10 The base 31 has a threaded hole, and the first limiting member 32 is a screw. One end of the screw passes through the threaded hole and is located at the bottom of the fixing frame 1. The other end of the screw is fixed to the stretch film and is used to drive the screw to rotate by rotating the stretch film.

[0055] Specifically, when the wrapping film roll is fixed to the first limiting member 32, pulling one end of the wrapping film roll causes the screw to rotate relative to the base 31. This, in turn, raises the position of the screw under the transmission of the thread, thus raising the position of the wrapping film roll. This ensures that the wrapping film is spirally rising from the bottom to the top of the tooling cart 7, improving the sealing effect of the wrapping film on the tooling cart 7. Simultaneously, it reduces the number of times packaging workers need to adjust the height of the platform 3, improving packaging efficiency. Furthermore, a limiting member can be provided at the bottom end of the screw to prevent the screw from detaching from the base 31.

[0056] In a specific embodiment, reference is made to... Figure 2 and Figure 12 An arc-shaped guide structure is provided on the side of the guide part 11 opposite to the stage 3. The arc-shaped guide structure is located close to the guide hole and extends from the bottom of the guide hole to the top of the guide hole.

[0057] Specifically, the arc-shaped guide structure is positioned close to the guide hole to prevent the stretch film from being cut by the guide hole. The arc-shaped guide structure extends from the bottom to the top of the guide hole to guide stretch film of different heights or sizes, thereby preventing the stretch film from being cut at different heights.

[0058] The arc-shaped guide structure can protrude to the side away from the platform 3 to increase the angle between the stretch film and the tooling carriage 7 during the guiding process, thereby preventing the side of the tooling carriage 7 from tearing the stretch film. Of course, the arc-shaped guide structure can also be as follows: Figure 12 The guide post shown has a larger diameter. In a specific embodiment, refer to... Figure 1 The relationship between the height H1 of the adjusting component 4 and the height H2 of the fixing frame 1 is satisfied that H1:H2 = 0.5~1.

[0059] Specifically, to reduce the bending over of packaging workers, the height H1 of the adjusting component 4 can be appropriately increased, thereby facilitating the adjustment of the height of the platform 3 by the packaging workers. Preferably, H1:H2 = 0.5, 0.6, 0.7, 0.8, 0.9 or 1.

[0060] In a specific embodiment, the fixed frame 1 is provided with a first guide rail 12 and a second guide rail 13 arranged parallel to the first guide rail 12. The first guide rail 12 and the second guide rail 13 are both arranged along the height direction of the fixed frame 1. The platform 3 is slidably arranged on the first guide rail 12, and the adjustment component 4 is slidably connected to the second guide rail 13.

[0061] Specifically, the first guide rail 12 can be configured as one (not shown in the diagram) or two (see reference). Figure 1 (One or more rails are not shown in the diagram). The more first guide rails 12 are set, the more stable the guidance of the stage 3. Similarly, the second guide rail 13 can be set with one (not shown in the diagram) or two (see reference). Figure 1 (or multiple lines (not shown in the illustration)).

[0062] like Figure 1 As shown, the fixed frame 1 is a frame structure. Two first guide rails 12 are provided, with the two first guide rails 12 located on both sides of the platform 3. The platform 3 is slidably connected to the two first guide rails 12 to achieve lifting. Two second guide rails 13 are provided, with the two second guide rails 13 located on both sides of the platform 3. The adjusting component 4 is slidably connected to the two second guide rails 13 to achieve lifting.

[0063] In a specific embodiment, reference is made to... Figure 1 , Figure 3 , Figure 4 as well as Figure 8 The adjustment component 4 has an L-shaped structure and includes a first support 41, a second support 42, and at least two handles 43. The handles 43 are connected between the first support 41 and the second support 42, and the handles 43 are spaced apart along one end of the adjustment component to the other end.

[0064] Specifically, the adjustment component 4 includes two parallel first support members 41 and second support members 42, and at least two handles 43. The two handles 43 are arranged along the extending direction of the first support member 41 or the second support member 42 to facilitate the packaging worker in sliding the adjustment component 4. Specifically, when multiple handles 43 are provided, the multiple handles 43 are evenly spaced along the extending direction of the first support member 41 or the second support member 42 to facilitate the packaging worker in observing the distance the adjustment component 4 has moved, thereby facilitating relatively precise adjustment of the height of the platform 3.

[0065] In a specific embodiment, reference is made to... Figure 1 , Figure 3 , Figure 4 as well as Figure 7 The transmission component 2 includes a pulley block 21 and a traction rope 22. The pulley block 21 is fixed on the fixed frame 1, and the traction rope 22 is wound around the pulley block 21. One end of the traction rope 22 is connected to the platform 3, and the other end of the traction rope 22 is connected to the adjustment component 4.

[0066] Specifically, pulley block 21 can be used to change the direction and magnitude of the traction force to reduce the traction force required by adjusting component 4. Pulley block 21 can be provided in two (not shown in the figure) or multiple (see reference). Figure 3 and Figure 4 The pulley block 21 includes a first pulley, a second pulley, and a third pulley, all mounted on the fixed frame 1. The first pulley is located on top of the platform 3, the second pulley is located on top of the adjusting assembly 4, and the third pulley is located between the first and second pulleys. One end of the traction rope 22 is connected to the platform 3, and the other end of the traction rope 22 passes sequentially around the first, third, and second pulleys before connecting to the adjusting assembly 4. It should be noted that the traction rope 22 can be made of steel wire, chain, or other structures capable of traction.

[0067] In a specific embodiment, reference is made to... Figure 1 , Figure 3 , Figure 4 , Figure 11 as well as Figure 12 The bottom of the fixed frame 1 is equipped with a set of casters 6.

[0068] Specifically, the caster wheel assembly 6 is located at the bottom of the fixed frame 1 to guide the fixed frame 1. Furthermore, the caster wheel assembly 6 is also provided with a mudguard, which is located at the top of the caster wheel assembly 6 to prevent dust or waste from accumulating on the caster wheel assembly 6.

[0069] Reference for the use of the wrapping film guide device Figure 2 as well as Figures 4 to 6During the packaging process from section a to section b of the packaging trolley 7, the platform 3 is moved to position A by lifting and adjusting component 4, one end of the stretch film is fixed to the packaging trolley 7, and the stretch film guide device is pushed to rotate around the packaging trolley 7 to complete the packaging of section a to section b of the packaging trolley 7; the platform 3 is moved to position B by lifting and adjusting component 4, and the stretch film guide device is pushed to continue rotating around the packaging trolley 7 to complete the packaging of section b to section c of the packaging trolley 7.

[0070] The stage 3 can be moved to point C by adjusting component 4. At this point, the stretch film is at the top of point C, and the angle of the stretch film can be adjusted. After the angle of the stretch film is adjusted, the stage 3 can be moved to point B by pulling down the adjusting component 4, which will push the stretch film guide device to rotate around the tooling carriage 7, thus completing the packaging of section b to c of the tooling carriage 7. The stage 3 can be moved to point A by pulling down the adjusting component 4 again, which will push the stretch film guide device to continue rotating around the tooling carriage 7, thus completing the packaging of section a to b of the tooling carriage 7.

[0071] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0072] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
