Description

Technical Field

[0001] The utility model relates to the field of packaging machines, in particular to an overload protection structure for a push plate of a packaging machine. Background Art

[0002] During the operation of the pusher of the packaging machine, the swing arm is connected to the sliding bearing through a connecting rod, and the push plate is fixed on the sliding bearing seat. It can move back and forth on the fixed plate to push the single or multiple packages into the packaging film. When a single or multiple packages of household paper enter the pusher of the packaging machine, due to the dragging of the bottom of the single package, the single package is skewed, etc., the single package or multiple packages collide with other devices, causing the package to be stuck.

[0003] Due to the lack of an overload protection structure, the push plate is subjected to increased force when pushing the package into the packaging film, causing a series of problems such as push plate deformation, bearing damage, connecting rod breakage, and rocker arm deformation, which increase maintenance costs and affect the effective operation of the equipment.

[0004] Therefore, it is necessary to develop a packaging machine push plate overload protection structure specifically to solve the above problems. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the prior art, the utility model provides a packaging machine push plate overload protection structure. When the push plate has abnormal conditions such as package jamming, the equipment can be shut down in time to avoid problems such as push plate deformation, bearing damage, connecting rod breakage, and rocker arm deformation.

[0006] Technical solution: The utility model is a packaging machine push plate overload protection structure, which is characterized by: it includes a push plate of the packaging machine, the push plate is connected to the fixed plate through a sliding bearing, the sliding bearing is connected to the rocker arm through a connecting rod, a fixed iron block is provided on the rocker arm, the rocker arm is fitted with a magnet on the bearing fixed plate through the fixed iron block, a sensing photoeye is provided on the side of the fixed iron block, and the sensing photoeye is connected to the controller.

[0007] The push plate moves left and right on the fixed plate through a sliding bearing to deliver a single package or multiple packages of paper into the packaging film.

[0008] Wherein, the push plate is fixedly connected to the sliding bearing, and the sliding bearing is movably connected to the fixed plate.

[0009] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: when the push plate is stuck or other abnormal conditions occur, the utility model stops the equipment in time to avoid problems such as push plate deformation, bearing damage, connecting rod breakage, swing rod deformation, etc. The utility model improves equipment efficiency, reduces equipment maintenance costs, is simple to operate, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the structure of the utility model;

[0011] In the figure, 1 is a push plate; 2 is a sliding bearing; 3 is a fixed plate; 4 is a connecting rod; 5 is a swing rod; 6 is a fixed iron block; 7 is a magnet; 8 is a bearing fixing plate; 9 is a sensing photoeye; and 10 is a controller. DETAILED DESCRIPTION

[0012] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0013] The push plate overload protection structure of the packaging machine of the utility model comprises a push plate 1 of the packaging machine, the push plate 1 is connected to the fixed plate 3 through a sliding bearing 2, the sliding bearing 2 is connected to the swing rod 5 through a connecting rod 4, a fixed iron block 6 is provided on the swing rod 5, the swing rod 5 is fitted with a magnet 7 on the bearing fixed plate 8 through the fixed iron block 6, a sensing photoeye 9 is provided on the side of the fixed iron block 6, and the sensing photoeye 9 is connected to a controller 10. Among them, the push plate 1 moves left and right on the fixed plate 3 through the sliding bearing 2 to feed a single bag or a multi-treasure paper into the packaging film. The push plate 1 is fixedly connected to the sliding bearing 2, and the sliding bearing 2 is movably connected to the fixed plate 3.

[0014] The utility model adds a fixed iron block 6 to the swing rod 5, adds a strong magnet 7 (the magnetic force is greater than the overload force when the push plate pushes the package) to the bearing fixing plate 8, and installs a sensing photoeye 9 that can sense the fixed iron block 6. The sensing photoeye 9 signal is connected to the controller 10. The fixed iron block 6 and the magnet 7 are attracted during the normal operation of the pusher of the packaging machine. When the push plate 1 is stuck in the package, the force on the push plate 1 is greater than the suction force between the magnet 7 and the fixed iron block 6, and the magnet 7 is separated from the fixed iron block 6. The sensing photoeye 9 cannot sense the fixed iron block 6, and transmits the signal to the controller 10, and the equipment stops. When the abnormality is eliminated, the push plate 1 returns to its original position, the magnet 7 is attracted again, the sensing photoeye 9 senses the fixed iron block 6, and the signal is transmitted to the controller 10, and the controller 10 controls the equipment to restart.
