[0028] 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: an unwinding machine for packaging bag printing, comprising a mounting base 1, a fixing plate 4 is fixedly connected to the left and right sides of the top of the mounting base 1, a connecting block 501 is slidably connected to the top of the fixing plate 4, a card slot 505 is provided on the front and rear sides of the connecting block 501, two slide slots 503 are provided inside the fixing plate 4, a slide plate 504 is slidably connected inside the slide slot 503, a pressing rod 502 is fixedly connected to the outside of the slide plate 504, a connecting slot 508 is provided on the inner side wall of the slide slot 503, a bidirectional telescopic rod 507 is rotatably connected inside the connecting slot 508, a slide slot 2 509 is provided on the inner side wall of the slide slot 2 509, and the slide slot 2 509 is provided on the inner side wall of the slide slot 2 509. 09 is fixedly connected to the inside with a second spring 510, one end of the second spring 510 is fixedly connected to a clamping block 506, and the unwinding roller 3 is movably connected between the two connecting blocks 501 through a bearing, and an extrusion assembly is installed on the top of the mounting base 1, so that the operator can quickly remove the unwinding roller 3 for maintenance, cleaning or replacement, which is more convenient than the prior art installation method using multiple bolts. The function of the connecting groove 508 is to give the bidirectional telescopic rod 507 a rotation effect, and the function of the second spring 510 is to give the clamping block 506 an outward force, so that the clamping block 506 can be stuck in the clamping groove 505, thereby ensuring the stability of the unwinding roller 3 when working.

[0030] Specifically, by pressing the pressing rod 502 inward, the slide plate 504 moves along the inner wall of the first slide groove 503, and further causes one end of the two-way telescopic rod 507 to swing. At this time, under the action of the traction force of the two-way telescopic rod 507, the clamping block 506 is retracted into the second slide groove 509. At this time, the clamping groove 505 and the clamping block 506 are separated from each other. The user moves the connecting block 501 upward to complete the disassembly of the unwinding roller 3.

[0031] The extrusion assembly includes two fixed rods 201, and the two fixed rods 201 are fixedly connected to the top left side of the mounting base plate 1, the outside of the fixed rod 201 is fixedly connected to a fixed seat 202, the inside of the fixed seat 202 is provided with a mounting groove 206, the inside of the mounting groove 206 is slidably connected to a movable plate 208, one side of the movable plate 208 is fixedly connected to a first spring 207, the other side of the movable plate 208 is fixedly connected to a movable rod 203, the other end of the movable rod 203 is fixedly connected to a connecting block 204, and the insides of the two connecting blocks 204 are rotatably connected to extrusion rollers 205.

[0032] Specifically, under the elastic force of the first spring 207, the movable plate 208 moves along the inner wall of the installation groove 206, and further drives the movable rod 203 to move synchronously, and under the traction force of the movable rod 203, drives the connecting block 204 to move synchronously, so that the squeezing roller 205 can fit tightly against the outside of the unwinding roller 3, thereby ensuring that the rolled packaging bag material remains flat during the unwinding process, avoiding the problem of reduced printing quality due to curling, loosening and other problems of the material during the printing process.

[0033] One end of the first spring 207 is fixedly connected to the inner wall of the fixing seat 202, the outer surface of the squeezing roller 205 is in contact with the outer surface of the unwinding roller 3, one end of the bidirectional telescopic rod 507 is rotatably connected to the outside of the slide plate 504, and the other end of the bidirectional telescopic rod 507 is rotatably connected to the outside of the clamping block 506;

[0034] Please refer to the attached Figure 4 The longitudinal section of the card block 506 is set to be square, and the card block 506 and the interior of the card slot 505 are locked together;

[0035] Specifically, the block 506 and the slot 505 cooperate with each other, thereby ensuring the stability of the unwinding roller 3 during installation.

[0036] Please refer to the attached Figure 3 and attached Figure 4 , one end of the pressing rod 502 away from the sliding plate 504 penetrates the outer wall of the fixing plate 4 and extends to the outside thereof, and the outside of the pressing rod 502 is provided with anti-slip grooves;

[0037] Specifically, the anti-slip pattern is designed to increase the friction between the pressing rod 502 and the user, making the pressing rod 502 easier to move.

[0038] Please refer to the attached Figure 1 , a motor 6 is installed on the outside of one of the fixing plates 4, and the output end of the motor 6 is detachably connected to the outside of one of the connecting blocks 501;

[0039] Specifically, by starting the motor 6 , the internal bearing of the connection block 501 rotates, and further drives the unwinding roller 3 to rotate. The function of the detachable connection is to prevent the motor 6 from hindering the disassembly of the unwinding roller 3 .

[0040] Please refer to the attached Figure 3 and attached Figure 4 One end of the second spring 510 away from the block 506 is fixedly connected to the inner wall of the second slide groove 509 .

[0041] Specifically, by loosening the pressing rod 502 , the clamping block 506 is driven to be clamped into the clamping slot 505 under the elastic force of the second spring 510 , thereby completing the installation of the unwinding roller 3 .

[0042] Working principle: When using the device, first start the motor 6 to drive the unwinding roller 3 to rotate, so that the printed packaging bag is unrolled. During the unwinding process, under the elastic force of the first spring 207, the movable plate 208 moves along the inner wall of the mounting groove 206, and further drives the movable rod 203 to move synchronously, and under the traction force of the movable rod 203, drives the connecting block 204 to move synchronously, so that the squeezing roller 205 can be closely attached to the outside of the unwinding roller 3, thereby ensuring that the rolled packaging bag material remains flat during the unwinding process;

[0043] When the unwinding roller 3 needs to be removed, the pressing rod 502 is pressed inwardly, so that the slide plate 504 moves along the inner wall of the slide groove 1 503, and further makes one end of the two-way telescopic rod 507 swing. At this time, under the action of the traction force of the two-way telescopic rod 507, the card block 506 is retracted into the interior of the second slide groove 509. At this time, the card groove 505 and the card block 506 are separated from each other, and the user moves the connecting block 501 upward to complete the disassembly of the unwinding roller 3. Similarly, when the unwinding roller 3 needs to be installed, the above-mentioned steps of pressing the pressing rod 502 are repeated, so that the card block 506 moves along the inner wall of the second slide groove 509, and the second spring 510 is in a compressed state. At this time, the connecting block 501 is inserted into the groove at the top of the fixing plate 4, and the pressing rod 502 is released. Under the elastic force of the second spring 510, the card block 506 is driven to be inserted into the card groove 505, and the installation of the unwinding roller 3 is completed. The operation is simple and convenient for people to use.
