It is usually made of plastic materials such as polyethylene or polyvinyl chloride, and has certain flexibility and tensile resistance. In the production process of cling film, it needs to go through multiple process operations. At this time, feeding equipment is needed between each process to ensure the normal transportation of cling film packaging bags. However, when the existing conveying equipment is conveying the cling film, it is difficult to effectively position the placed cling film packaging bags. The placement position of the cling film packaging bags is inconsistent, and sometimes the operator is required to manually adjust the position of the packaging bag to avoid position offset causing abnormalities in subsequent processes.

[0003] Therefore, a circulating feeding device for fresh-keeping film packaging is now developed in response to the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0020] Example 1

[0021] A circulating feeding device for fresh-keeping film packaging, such as Figure 1 As shown, it includes a mounting frame 1, a driving motor 2 is installed on the right side of the front of the mounting frame 1, the output shaft of the driving motor 2 is set to face left, a sprocket assembly 3 is connected between the output shaft of the driving motor 2 and the mounting frame 1, the sprocket assembly 3 includes a chain, a sprocket and a placement plate, the output shaft of the driving motor 2 and the rear of the mounting frame 1 are connected with sprockets, chains are wound between the left and right sides of the sprocket, placement plates for placing cling film packages are connected between the chains, push plates 4 for separating and pushing cling film packages are connected to the placement plates of the sprocket assembly 3, and a calibration mechanism 5 for automatically calibrating the position of cling film packages of different specifications is set at the front of the mounting frame 1.

[0022] like Figure 1-Figure 3As shown, the calibration mechanism 5 includes a first mounting seat 51, and the first mounting seat 51 is connected to both sides of the front inner left and right sides of the mounting frame 1 by bolts, and a calibration component 52 for pushing and calibrating the cling film package is slidably arranged on the first mounting seat 51, and the calibration component 52 includes a T-shaped push plate, a guide frame and a boost spring, and the left and right sides of the front inner left and right sides of the mounting frame 1 are connected to the guide frame, and a T-shaped push plate is slidably arranged in the guide frame, and a boost spring is connected between the T-shaped push plate and the adjacent guide frame, and a reset plate 53 is connected to the rear side of the calibration component 52. , a locking piece 54 is rotatably provided on the reset plate 53, a fixing piece 55 is connected to the left and right sides of the inner front part of the mounting frame 1, and the locking piece 54 is clamped with the adjacent fixing piece 55, and a second mounting seat 56 is connected to the left and right sides of the inner front part of the mounting frame 1, and a rotating piece 57 is rotatably provided on the second mounting seat 56, and the rotating piece 57 can push the adjacent locking piece 54, and the rear side of the rotating piece 57 is an arc surface structure, and a torsion spring 58 is connected between the rotating piece 57 and the adjacent second mounting seat 56, and the rear side of the rotating piece 57 can contact with the push plate 4.

[0023] It should be noted that in the production and feeding process of plastic wrap packaging, in order to ensure the normal progress of subsequent processes and reduce the workload of operators, the present device can be used to assist in feeding the plastic wrap packaging bags. First, the plastic wrap packaging bags are placed on the placement plate in the sprocket assembly 3, and then the drive motor 2 is started. The output shaft of the drive motor 2 will drive the sprocket assembly 3 to operate, thereby starting the automatic conveying of the plastic wrap packaging bags. During the operation of the sprocket assembly 3, the push plate 4 will move synchronously, thereby contacting the rotating member 57 during the movement. The rotating member 57 will be pushed by the push plate 4 to produce a deflection, and then push the adjacent locking member 54, so that The locking members 54 are no longer engaged with the adjacent fixing members 55. In the initial state, the booster springs in the calibration assembly 52 are in a stressed and compressed state. When the locking members 54 are no longer engaged with the adjacent fixing members 55, under the action of the booster springs, the T-shaped push plate will slide forward along the guide frame, thereby driving the reset plate 53 to slide forward synchronously, and then automatically calibrating the position of the cling film packaging bag so that the cling film packaging bag can be in the center position. After that, as the push plate 4 continues to move, the push plate 4 will contact the reset plate 53, thereby pushing the reset plate 53 to slide outward and reset, thereby causing the booster springs to return to the stressed state again, and the locking members 54 will be re-engaged with the adjacent fixing members 55.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1 and Figure 4As shown, it also includes a clamping mechanism 6, which includes a mounting plate 61. The mounting plate 61 is installed on the front of the mounting frame 1 by bolts. A plurality of conveying rollers 62 are rotatably arranged in the middle of the mounting plate 61. Two mounting parts 63 are through-connected to the upper part of the mounting plate 61. A clamping wheel 65 for clamping and limiting the cling film packaging bag in the discharging state is slidably arranged at the lower part of the mounting part 63. Two adapting springs 64 are connected between the clamping wheel 65 and the adjacent mounting parts 63.

[0026] It should be noted that as the plastic wrap packaging bag completes the calibration work and continues to move forward to discharge, the plastic wrap packaging bag is clamped and limited by the conveying roller 62 and the pressure wheel 65, so that the plastic wrap packaging bag can be discharged in a compressed state to avoid the plastic wrap packaging bag from being scattered. In the process of compressing the plastic wrap packaging bag, the adapter spring 64 will always buffer the pressure wheel 65, so that the pressure wheel 65 can adapt to plastic wrap packaging bags of different thicknesses.
