DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a fully automatic continuous food packaging film bag making machine, comprising a machine base 1, two fixed plates 2 are fixed on the top of the machine base 1, a winding mechanism 300 for stable winding is installed between the opposite sides of the two fixed plates 2, a mounting plate 4 is fixed between the opposite sides of the two fixed plates 2, and a positioning component 500 for elastic positioning is installed at the bottom of the mounting plate 4; through the coordinated use of the winding mechanism 300 and the positioning component 500 on the top of the machine base 1, the processed food bags can be effectively and stably continuously wound, and the wound food bags can be pressed to enable them to smoothly carry out the continuous winding work, and at the same time, by adding a structure for limiting, the food bags can be bent to a certain extent during the transportation process, thereby increasing the winding tensioning effect, and the wound food bags can also be conveniently disassembled and removed, so that the food packaging film bag making work can be carried out conveniently, effectively improving the practicality of the food packaging film bag making machine, and facilitating automatic and continuous production work.

[0023] In this embodiment, the rolling mechanism 300 is a structure for continuously and smoothly rolling up the food bag.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the winding mechanism 300 includes a rotating rod 301 rotatably connected between opposite sides of two fixed plates 2 through a bearing, a limiting roller 302 fixed to the outside of the rotating rod 301, a driving mechanism 303 fixedly installed on the right side of the right fixed plate 2, a connecting member 304 rotatably connected to the left side of the right fixed plate 2 through a bearing, a mounting groove 305 opened on the left side of the connecting member 304, a matching cylinder 306 fixed to the right side of the left fixed plate 2, a matching groove 307 opened on the top of the matching cylinder 306, two fixed rods 308 respectively inserted into the inner side of the mounting groove 305 and the inner side of the matching cylinder 306, a winding roller 309 fixedly installed between the opposite ends of the two fixed rods 308, a movable plate 310 located above the winding roller 309, and a clamping member 311 fixedly installed at the bottom of the movable plate 310 and capable of applying pressure to the winding roller 309.

[0025] It should be noted that the limiting roller 302 is located on the back side of the bottom of the winding roller 309, so that the position of the limiting roller 302 can be staggered with the position of the winding roller 309, so that the food bag passing through the bottom of the limiting roller 302 can be tensioned and wound to the outside of the winding roller 309, and the output shaft of the driving mechanism 303 passes through the right side of the right fixed plate 2 and is fixedly connected to the right end of the connecting member 304, so that the driving mechanism 303 can drive the connecting member 304 to move, and the driving mechanism 303 can be a servo motor.

[0026] In addition, the interior of the matching groove 307 is connected to the interior of the matching tube 306, and the right side of the matching groove 307 is open, so that the left fixing rod 308 can be moved from the outside to the inside of the matching tube 306 for placement, and can also be moved out from the inside of the matching tube 306.

[0027] In addition, the outer side of the right fixing rod 308 is connected to the outer side of the connecting piece 304 by four bolts, so that the bolts can facilitate the fixing of the right fixing rod 308 and facilitate removal, so that the right fixing rod 308 can be connected to the connecting piece 304, so that it can be driven by the connecting piece 304 to rotate, and under the support of the matching cylinder 306, the two fixing rods 308 can rotate normally, so that the winding roller 309 can perform the winding work.

[0028] At the same time, the pressing member 311 includes a pressing box fixed to the bottom of the movable plate 310, a round rod rotatably connected to the inner side of the pressing box through a bearing, a rubber roller fixed to the outer side of the round rod, and brushes fixed to the outer side of the rubber roller and evenly distributed. The pressing member 311 is located directly above the winding roller 309 and can be fitted with the top of the winding roller 309, so that the pressing member 311 can utilize the elastic pressing effect of the rubber roller and the smoothing effect of the brush, thereby being able to smooth and press the food bag rolled up on the outer side of the winding roller 309, so that it can be rolled up smoothly and effectively.

[0029] In this embodiment, the positioning assembly 500 is a structure for applying elastic compression and limiting to the food bag.

[0030] like Figure 1 and Figure 2 As shown, the positioning assembly 500 includes four positioning rods 501 fixed to the top of the movable plate 310, four linear slides 502 fixed to the top of the mounting plate 4, two connecting rods 503 hinged to the top of the movable plate 310 through a pin shaft, two sliding grooves 504 opened at the bottom of the mounting plate 4, a support rod 505 fixed to the inner side of the sliding groove 504, a sliding block 506 slidably connected to the outer side of the support rod 505, and two elastic members 507 respectively fixed to the opposite sides of the two sliding blocks 506.

[0031] It should be noted that the top end of the positioning rod 501 passes through the mounting plate 4 and the corresponding linear slide 502 in sequence, so that the positioning rod 501 can slide smoothly on the inner side of the corresponding linear slide 502, and the two connecting rods 503 are hinged to the top of the movable plate 310 through the same pin shaft, and the bottom of the sliding block 506 is hinged to the top end of the corresponding connecting rod 503 through the pin shaft. The two connecting rods 503 are distributed in a V shape, so that when the movable plate 310 moves, the two connecting rods 503 distributed in a V shape can push the two sliding blocks 506 to move respectively.

[0032] In addition, the opposite sides of the two elastic members 507 are fixedly connected to the opposite sides of the two sliding grooves 504 respectively. The elastic members 507 are located on the outer sides of the corresponding support rods 505. The elastic members 507 can be springs, so that the sliding block 506 can stretch the elastic members 507 when moving, thereby utilizing the elastic force recovery effect of the elastic members 507 to realize the function of elastic extrusion limiting.

[0033] The working principle of the above embodiment is:

[0034] When the continuous bag making work of the food packaging film is carried out, the food bag that has been pressed and connected passes through the bottom of the limiting roller 302 and is then transported upward and rolled up through the top of the outer side of the winding roller 309, so that the limiting roller 302 can play a certain tensioning role on the food bag, making it easy to roll up smoothly, and the food bag rolled up on the outer side of the winding roller 309 is pressed by the pressing member 311, and as the outer diameter of the winding roller 309 continues to increase, the food bag presses the pressing member 311 upward, so that the connecting rod 503 drives the corresponding sliding block 506 to slide on the outer side of the support rod 505, so that the elastic member 507 is stretched, and under the elastic force recovery action of the elastic member 507, the pressing member 311 is applied downward pressure through the connecting rod 503, so that the food bag on the outer side of the winding roller 309 is pressed by the pressing member 311, so that it can be stably rolled and wound, which is conducive to automatic and continuous production work.

[0035] Compared with the prior art, the fully automatic continuous food packaging film bag making machine, through the coordinated use of the winding mechanism 300 on the top of the machine base 1 and the positioning assembly 500, can effectively and stably continuously wind up the processed food bags, and by pressing the rolled food bags, it can smoothly carry out the continuous winding work, and at the same time, by adding a structure for limiting, the food bags can achieve a certain bending during the transportation process, thereby increasing the winding and tensioning effect, and can also facilitate the disassembly and removal of the rolled food bags, so that the food packaging film bag making work can be carried out conveniently, effectively improving the practicability of the food packaging film bag making machine, being conducive to automatic and continuous production work, and solving the problem that the existing bag making machines for food bag production are prone to looseness during the winding process, which is not conducive to continuous production.
