[0027] 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.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a transparent film packaging machine that facilitates material feeding, comprising:

[0029] The packaging machine body 1, and the feeding device for feeding products;

[0030] The feeding device includes a feeding mechanism 2, a feeding frame 3, a conveying mechanism 4, and a correction mechanism 5;

[0031] The feeding mechanism 2 is located at the feeding end of the packaging machine body 1, the loading frame 3 is installed on one side of the feeding mechanism 2, and the conveying mechanism 4 and the correction mechanism 5 are both installed on the loading frame 3 to convey the products.

[0032] The feeding frame 3 includes an outer frame 31 and a connecting frame 32 that are sequentially close to the feeding mechanism 2 from far to near. A guide frame 34 is provided between the outer frame 31 and the connecting frame 32 to reduce the space for product passage. A protruding frame 33 is provided on one side of the connecting frame 32 for the installation of the correction mechanism 5. The correction mechanism 5 is used to correct the angle of the product during conveying.

[0033] This utility model mainly utilizes the cooperation between the feeding mechanism 2, the feeding frame 3, the conveying mechanism 4, and the correction mechanism 5 that make up the feeding device. The conveying mechanism 4 can transport the products placed in the outer frame 31 in the same direction. Then, under the action of the guide frame 34, the products enter the one-way channel of the connecting frame 32. Under the action of the correction mechanism 5, the products are kept moving in a straight line during the conveying process, so that the feeding mechanism 2 can push the products into the packaging machine body 1, thereby improving the efficiency of product feeding, reducing the manual operation steps of the staff, and improving the efficiency of product packaging.

[0034] Furthermore, the correction mechanism 5 includes a second cylinder 51 disposed within the convex frame 33. The telescopic end of the second cylinder 51 is fixedly connected to a mounting frame 52. A side groove 54 is provided on one side of the mounting frame 52, and multiple sets of guide rollers 55 are rotatably mounted within the side groove 54, with the multiple sets of guide rollers 55 arranged at equal intervals. This design allows the second cylinder 51 to push the mounting frame 52 to move, enabling the multiple sets of guide rollers 55 to stably adhere to the product surface, facilitating rapid product alignment and ensuring linear product movement, thus simplifying product loading.

[0035] Furthermore, the mounting frame 52 is U-shaped, and two sets of stabilizing sleeves 53 are provided between the mounting frame 52 and the convex frame 33. The mounting frame 52 is slidably mounted on the inner wall of the convex frame 33. This design, through the stabilizing sleeves 53, improves the stability of the movement of the mounting frame 52, thereby ensuring the effectiveness of product calibration.

[0036] Furthermore, the conveying mechanism 4 includes two sets of first conveying rollers 41, two sets of second conveying rollers 43, and a linkage assembly 47. The two sets of first conveying rollers 41 are rotatably mounted inside the outer frame 31, and the two sets of second conveying rollers 43 are rotatably mounted inside the connecting frame 32. One set of first conveying rollers 41 and one set of second conveying rollers 43 are driven by the linkage assembly 47. A first conveyor belt 44 is mounted on the two sets of first conveying rollers 41, and a second conveyor belt is mounted on the two sets of second conveying rollers 43. The width of the first conveyor belt 44 is greater than that of the second conveyor belt 45. A guide frame 34 is positioned above the first conveyor belt 44. This design facilitates the conveying of large quantities of products via the first conveyor belt 44, and arranges and conveys the products under the action of the guide frame 34, allowing the products to enter the connecting frame 32 one by one, improving the efficiency of product loading and reducing manual operation steps.

[0037] Furthermore, the linkage assembly 47 includes a first synchronous pulley 471 mounted on the shaft end of the first conveyor roller 41 and a second synchronous pulley 472 mounted on the shaft end of the second conveyor roller 43. A synchronous belt 473 is provided between the first synchronous pulley 471 and the second synchronous pulley 472. One end of the first conveyor roller 41 away from the first synchronous pulley 471 passes through the outer frame 31 and is driven by the motor 42. A cover plate 35 is provided on the outer frame 31. The above design uses the cover plate 35 to conveniently protect the exposed first conveyor belt 44, avoiding personnel injury due to accidental operation and improving safety. At the same time, the linkage assembly 47 reduces the number of driving devices, thereby facilitating the simultaneous conveying of products by the first conveyor belt 44 and the second conveyor belt 45.

[0038] Furthermore, multiple sets of suction holes 46 are provided on the second conveyor belt 45, and a negative pressure chamber is formed between the second conveyor belt 45 and the connecting frame 32. A negative pressure fan 8 connected to the negative pressure chamber is provided on the other side of the connecting frame 32. This design allows the negative pressure fan 8 to draw air from the space between the second conveyor belt 45 and the connecting frame 32, thereby allowing outside air to enter the negative pressure chamber. The airflow creates suction to adsorb the product, improving the stability of the product during transport.

[0039] Furthermore, an adjustable frame 7 for guiding the product during transport is provided on the connecting frame 32, and a photoelectric switch 6 is located between the adjustable frame 7 and the protruding frame 33 on the connecting frame 32. This design allows the photoelectric switch 6 to easily monitor the product and transmit a signal to the controller (not shown in the figure) so that the correction mechanism 5 can be controlled to correct the product, thereby improving the stability of product transport.

[0040] Furthermore, the adjustable frame 7 includes an insert plate 71 that passes through the connecting frame 32. A straight plate 72 is fixedly connected to one side of the insert plate 71, and a locking bolt 73 that abuts against the insert plate 71 is threaded onto the connecting frame 32. This design allows for easy adjustment of the position of the insert plate 71 by tightening or loosening the locking bolt 73, which in turn facilitates adjustment of the position of the straight plate 72. This allows for easy adjustment of the product passage opening (the distance between the straight plate 72 and one side of the connecting frame 32), making it suitable for loading products of different specifications and improving practicality.

[0041] Furthermore, the feeding mechanism 2 includes a transfer frame 21 fixed to the feeding end of the packaging machine body 1. One side of the transfer frame 21 has a feeding hole 22 communicating with the connecting frame 32. A first cylinder 23 is installed inside the transfer frame 21, and the telescopic end of the first cylinder 23 is equipped with a pusher plate frame 24 for pushing products into the packaging machine body 1. This design allows the first cylinder 23 to easily drive the pusher plate frame 24 to push products into the packaging machine body 1. Simultaneously, the pusher plate frame 24 is U-shaped, which prevents the position of another set of products from shifting when one set of products enters the packaging machine body 1, thereby improving the stability of the products entering the packaging machine body 1.

[0042] In use, the operator places the product on the first conveyor belt 44 inside the first outer frame 31, and it is conveyed to the second conveyor belt 45 via the first conveyor belt 44. During the conveying process, the product is guided by the guide frame 34 to be conveyed in a straight line. According to the product specifications, the position of the insert plate 71 can be adjusted by tightening and loosening the locking bolt 73, thereby adjusting the gap between the straight plate 72 and the connecting frame 32 for secondary guidance of the product. Then, after the product passes the photoelectric switch 6, the photoelectric switch 6 transmits a signal to the controller, and the controller controls the second conveyor belt 45. The two cylinders 51 move the mounting frame 52, causing the multiple sets of guide rollers 55 on the mounting frame 52 to contact the product, making the product move against the inner wall of the connecting frame 32. The suction holes 46 on the second conveyor belt 45 cooperate with the negative pressure chamber and the negative pressure fan 8 to use negative pressure to adsorb and fix the product, so that the product can be transported stably. When the product is transported into the transfer frame 21 of the feeding mechanism 2, the first cylinder 23 pushes the pusher plate frame 24 to push the product into the packaging machine body 1, completing the feeding process and realizing efficient and accurate feeding operation of the transparent film packaging machine.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
