Description

Technical Field

[0001] The utility model belongs to the technical field of CPP film winding, and particularly relates to a CPP film winding mechanism for food packaging. Background Technique

[0002] CPP film is a polypropylene (PP) film produced by the casting extrusion process in the plastic industry. Different from BOPP (biaxial polypropylene) film, CPP film is a non-oriented film. Strictly speaking, CPP film has a certain orientation only in the longitudinal (MD) direction, mainly due to the process nature. During processing, excellent clarity and smoothness are formed on the film by rapid cooling on the cold casting roll.

[0003] In the process of realizing the utility model, the inventor found that at least the following problems exist in this technology: When processing CPP film, a winding mechanism is needed to wind it into a cylinder shape, so as to facilitate storage, storage and transportation. For the current winding mechanism, usually external tools are needed to position the winding drum when installing the winding drum, and the same tools are needed to complete the removal of the winding drum, which makes the manual participation of personnel more, bringing a greater burden to the staff (such as the patent with the application number CN201520402573.7 - the blown film winding device, its main rotating shaft is arranged between two auxiliary rotating shafts, and the steps of manually replacing the main rotating shaft are more cumbersome, resulting in a greater burden on personnel).

[0004] Therefore, we propose a CPP film winding mechanism for food packaging to solve the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a CPP film winding mechanism for food packaging, which greatly simplifies the process of disassembling and assembling the winding drum, reduces the manual participation of personnel, and reduces the burden on the staff, and can effectively solve the problems in the background technique.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A CPP film winding mechanism for food packaging, including a base and a winding module located above the base, characterized in that a fixed motor is horizontally installed on one side wall of the base, a top groove is formed above the base, the output shaft of the fixed motor is coaxially connected with a first screw rod, a bottom sliding seat is threadedly sleeved on the first screw rod, and the bottom sliding seat is attached to the inner wall of the top groove, so that when the first screw rod rotates driven by the fixed motor, the bottom sliding seat can be driven to translate along the inner wall of the top groove;

[0008] The winding module includes a movable seat welded on the bottom slide, a winding seat adapted to the movable seat, a winding motor horizontally mounted on the outer wall of the winding seat, an inner support shaft coaxially connected to the output shaft of the winding motor, and a reel fixedly sleeved on the inner support shaft, wherein the CPP film is wound on the reel, and a circular edge is provided on both sides of the reel, so that the reel is in an I-shape as a whole, thereby limiting the CPP film and preventing it from falling;

[0009] A movable motor is horizontally installed on the outer wall of the movable seat, wherein the output shaft of the movable motor is coaxially connected with the second screw, and a side groove is formed on the inner wall of the movable seat, wherein the second screw is threadedly sleeved with a translation block, and the translation block is in contact with the inner wall of the side groove, so that when the second screw is driven by the movable motor to operate, it can drive the translation block to translate along the inner wall of the side groove, and an adapter block is rotatably connected to the translation block, and a spline groove is formed on the reel, wherein the inner support shaft and the adapter block are spline-matched with the spline groove. When the reel is installed on the attached Figure 1 When the position is as shown in , the adapter block fits the inner support shaft perfectly.

[0010] As a preferred implementation scheme, the first screw is horizontally arranged in the top groove, and both sides of the first screw are rotatably connected to the base; so that the first screw can run stably under the drive of the fixed motor, and the fixed motor, the winding motor and the movable motor all need to be powered by external power facilities.

[0011] As a preferred implementation scheme, the winding motor and the inner support shaft are respectively located on both sides of the winding seat, wherein the winding seat is L-shaped, and the inner support shaft is horizontally arranged and rotatably connected to the winding seat; so that the inner support shaft can run stably under the drive of the winding motor.

[0012] As a preferred embodiment, a ring-shaped baffle is fixedly welded on the side of the inner support shaft close to the winding motor, wherein the baffle fits the reel, so that the position of the reel close to the winding motor is fixed.

[0013] As a preferred embodiment, the second screw is horizontally arranged in the side groove, and the second screw is rotatably connected to the movable seat; so that the second screw can run stably under the drive of the movable motor.

[0014] To sum up, the technical effects and advantages of the utility model are:

[0015] After the CPP film is wound up in the upper winding seat, the CPP film winding mechanism for food packaging first drives the movable motor to separate the adapter block from the roll, and then the fixed motor drives the first screw to operate, so that the movable seat is separated from the upper winding seat. At this time, the roll can be removed from the inner support shaft by horizontal sliding, thereby greatly simplifying the process of disassembling and assembling the roll, reducing the manual participation of personnel, and alleviating the burden on the staff; ​

[0016] For the winding mechanism of the CPP film for food packaging, when installing the reel, first fit the spline groove with the inner support shaft until the reel is in contact with the retaining disc. Then drive the fixed motor to drive the movable seat to translate to a position adapted to the winding seat. Next, drive the movable motor to operate and drive the second screw to rotate, so that the translation block translates along the inner wall of the side groove and drives the adapter block to insert into the spline groove, and the installation of the reel can be completed, making the installation of the reel more convenient and labor-saving.
