Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, and in particular to a stretch film packaging device. Background Technology

[0002] Most products need to be packaged after production. This not only improves the product's appearance but also provides good protection. There are many types of packaging, with cardboard boxes being the most common. After packaging the products into cardboard boxes, to ensure the goods are waterproof and prevent them from scattering, they are usually wrapped a second time with stretch film.

[0003] Packaging is used to ensure that the packaged goods remain intact during transportation.

[0004] A search revealed, for example, a stretch film packaging device provided by patent publication number CN219821839U, which relates to the field of stretch film packaging, includes: a work frame, which is welded from square tubes, and there are multiple square tubes; a support base, which is set on the work frame, and there are multiple support bases, each with a through hole; a first rotating shaft, which is set in the through hole on the support base; a tray, which is set on the first rotating shaft and is used to place goods and rotate and flip the goods; a second rotating shaft, which is set in the through hole on the support base and is used to place and rotate the stretch film; and a locking component, which is set on the second rotating shaft and is used to fix the stretch film. The goods are easily and neatly packaged by flipping during the stretch film packaging process through the support and rotation of the tray.

[0005] Based on the above search and the findings of existing technologies, existing stretch film packaging devices similar to those disclosed above have a fixed height, making them inconvenient for wrapping taller cartons. Manual intervention increases labor costs and results in low wrapping efficiency. Therefore, a stretch film packaging device is proposed to improve upon these problems. Utility Model Content

[0006] The purpose of this application is to provide a stretch film packaging device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a stretch film packaging device, including a base, a rotating tray located on the upper side of the base, and a support assembly disposed between the base and the rotating tray. The support assembly includes a drive motor, a limiting sleeve, a limiting slide column, and a transmission frame.

[0008] The drive motor is installed at the bottom of the base, the limiting sleeve is coaxially fixed to the top output end of the drive motor, the limiting slide column is vertically fixed at the center of the bottom surface of the rotating tray, the lower end of the limiting slide column is vertically slidably sleeved on the inner side of the limiting sleeve, the transmission frame is rotatably installed on the lower end surface of the rotating tray, the outer side of the limiting sleeve is provided with a reciprocating thread, and a reciprocating bushing adapted to the reciprocating thread is installed on the transmission frame;

[0009] A limiting slide rod that slides through the transmission frame is vertically fixed at the upper end of the base.

[0010] As a further supplement to this solution, a mounting ring is rotatably mounted on the lower end of the rotating tray, and the mounting ring is coaxially arranged with the rotating tray, and the transmission frame is fixed to the mounting ring.

[0011] As a further supplement to this solution, a top-feeding component is installed on the limiting sleeve, and a through hole adapted to the top-feeding component is provided on the rotating tray.

[0012] As a further supplement to this solution, the top material assembly includes a sliding sleeve and a top material rod;

[0013] The sliding sleeve is fitted onto the outside of the limiting slide post, and the top material rod is vertically connected to the upper end of the sliding sleeve. The top material rod is adapted to the through hole.

[0014] As a further supplement to this solution, the vertical thread of the top rod penetrates the sliding sleeve frame.

[0015] As a further supplement to this solution, the sliding sleeve is vertically slidably sleeved on the outside of the limiting slide post, and a compression spring is fixed between the sliding sleeve and the rotating tray.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] 1. In this utility model, by cooperating with a drive motor, a limiting sleeve, a limiting slide column, and a transmission frame, after the carton is placed at the center of the upper end of the rotating tray, one end of the stretch film is fixed to the surface of the carton. Then, the drive motor drives the limiting sleeve to rotate the rotating tray through the limiting slide column. When the limiting sleeve rotates, the drive transmission frame moves up and down reciprocally, thereby moving the rotating tray and the carton up and down reciprocally through the mounting ring, realizing the full wrapping of the stretch film on the side of the carton, thus improving the wrapping efficiency.

[0018] 2. In this utility model, by setting the top material component, when the rotating tray moves down to the bottom position, the top material rod protrudes from the through hole onto the upper surface of the rotating tray, thereby lifting the carton on the rotating tray to one side, causing the carton to tilt, which makes it convenient for workers to flip the carton and wrap the carton completely, and also facilitates subsequent material unloading.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-5 The illustrated stretch film packaging device includes a base 1, a rotating tray 2 located on the upper side of the base 1, and a support component 3 disposed between the base 1 and the rotating tray 2.

[0028] The support component 3 includes a drive motor 31, a limiting sleeve 32, a limiting slide column 33, and a transmission frame 34. The drive motor 31 is installed at the bottom of the base 1. The limiting sleeve 32 is coaxially fixed to the top output end of the drive motor 31. The limiting slide column 33 is vertically fixed at the center of the bottom surface of the rotating tray 2. The lower end of the limiting slide column 33 is vertically slidably sleeved on the inner side of the limiting sleeve 32. The transmission frame 34 is rotatably installed on the lower end surface of the rotating tray 2. The outer side of the limiting sleeve 32 is provided with a reciprocating thread, and a reciprocating bushing adapted to the reciprocating thread is installed on the transmission frame 34. A limiting slide rod 35 that slides through the transmission frame 34 is vertically fixed at the upper end of the base 1.

[0029] The lower end of the rotating tray 2 is rotatably mounted with an installation ring 4, and the installation ring 4 is coaxial with the rotating tray 2. The transmission frame 34 is fixed to the installation ring 4.

[0030] Based on the above structural arrangement, after the carton is placed at the center of the upper end of the rotating tray 2, one end of the stretch film is fixed to the surface of the carton. Then, the drive motor 31 drives the limiting sleeve 32 to rotate the rotating tray 2 through the limiting slide column 33. When the limiting sleeve 32 rotates, the drive transmission frame 34 moves up and down reciprocally, thereby moving the rotating tray 2 and the carton up and down reciprocally through the mounting ring 4, realizing the full wrapping of the stretch film on the side of the carton and improving the wrapping efficiency.

[0031] In addition, a material ejector assembly is installed on the limiting slide sleeve 32, and a through hole 201 adapted to the material ejector assembly is provided on the rotating tray 2. Specifically, the material ejector assembly includes a sliding sleeve frame 5 and a material ejector rod 6. The sliding sleeve frame 5 is sleeved on the outside of the limiting slide column 33, and the material ejector rod 6 is vertically connected to the upper end of the sliding sleeve frame 5. The material ejector rod 6 is adapted to the through hole 201. The sliding sleeve frame 5 is vertically slidably sleeved on the outside of the limiting slide column 33, and a compression spring 7 is fixed between the sliding sleeve frame 5 and the rotating tray 2.

[0032] Based on the above-mentioned top-loading component, when the rotating pallet 2 moves down to the bottom position, the top-loading rod 6 protrudes from the through hole 201 from the upper surface of the rotating pallet 2, thereby lifting the carton on the rotating pallet 2 to one side, causing the carton to tilt, making it easier for the staff to flip the carton, and also facilitating subsequent unloading.

[0033] To facilitate adjustment of the lifting height of the carton by the top rod 6, the top rod 6 has a vertical thread that passes through the sliding sleeve 5. The lifting height of the top rod 6 can be adjusted simply by turning it.

[0034] Of course, the aforementioned top-loading assembly can also be a conventional electric push rod (not shown in the figure), which makes it easier to control the lifting height of the carton.

[0035] The working principle of this utility model is as follows: In the initial state, the rotating tray 2 is located on the top material rod 6. The operator vertically places the stretch film roll onto the conventional rotating roller. After placing the carton at the center of the upper end of the rotating tray 2, one end of the stretch film is fixed to the surface of the carton. For example, static electricity is used to make the end of the stretch film adhere to the surface of the carton. Then, the drive motor 31 drives the limiting slide sleeve 32 to rotate the rotating tray 2 through the limiting slide column 33. When the limiting slide sleeve 32 rotates, the drive transmission frame 34 moves up and down reciprocally, thereby moving the rotating tray 2 and the carton up and down reciprocally through the mounting ring 4, so as to achieve full wrapping of the stretch film on the side of the carton.

[0036] When the rotating pallet 2 moves down to the bottom position, the top material rod 6 protrudes from the through hole 201 from the upper end face of the rotating pallet 2, thereby pushing the carton on the rotating pallet 2 to one side, causing the carton to tilt, making it easier for the staff to flip the carton and wrap it completely.

[0037] When the rotating pallet 2 moves down to the bottom position again, the top bar 6 protrudes from the through hole 201 from the upper surface of the rotating pallet 2, thereby pushing the carton on the rotating pallet 2 to one side, causing the carton to tilt and making it easier to unload.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
