DETAILED DESCRIPTION

[0026] 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.

[0027] The utility model provides Figure 1-3 The bag making machine of a single-side opening bag on roll shown in the figure comprises a fixed frame 3 and a raw material roller 6 installed on the left side of the fixed frame 3;

[0028] A guide frame a4 is provided on the right side of the fixed frame 3;

[0029] A heat press 11 is provided on the right side of the guide frame a4 to perform heat sealing operation on the roll bag;

[0030] A cutting mechanism 13 is provided on the right side of the heat press 11 to leave an easy-to-tear rack on the roll bag. A positioning rod 16 is provided on the right side of the cutting mechanism 13 for fixing the reel for rewinding the roll bag. The roll bag is fixed on the raw material roller 6, and one end is guided into the heat press 11 for heat-sealing edge sealing. After edge sealing, the roll bag moves into the cutting mechanism 13 to cut an easy-to-tear tear strip, and then the reel is reeled by the reel fixed on the positioning rod 16.

[0031] A temperature conducting cylinder 23 is arranged on the upper side of the guide frame a4, and a low-temperature medium 20 is arranged inside the temperature conducting cylinder 23. When the roll bag contacts the temperature conducting cylinder 23, the low temperature transmitted by the low-temperature medium 20 can be transferred to the surface of the roll bag to cool the roll bag. The low-temperature medium 20 can be used as frozen ice water.

[0032] like Figure 2 and Figure 3 As shown, the upper outer wall of the guide frame a4 is fixedly connected with a fixed block 21, the upper outer wall of the fixed block 21 is provided with a positioning groove 22, the interior of the temperature conducting cylinder 23 is fixedly connected with a limiting rod 25, and the left side of the limiting rod 25 is sleeved with a positioning shaft 26 which is clamped in the positioning groove 22.

[0033] When the roll bag contacts the temperature conducting cylinder 23 and moves through the limiting rod 25 and the positioning shaft 26 , the temperature conducting cylinder 23 can rotate under the drive of the roll bag.

[0034] like Figure 5 As shown, a through hole 30 is opened on the left outer wall of the temperature conducting cylinder 23 to allow the low-temperature medium 20 to circulate, and a leak-proof cover 29 is clamped inside the through hole 30 to limit the position of the low-temperature medium 20. The left outer wall of the leak-proof cover 29 is fixedly connected to the handle 28, and a threaded sleeve 31 is provided on the right side of the through hole 30. The right outer wall of the leak-proof cover 29 is fixedly connected to a threaded block 27 that is screwed with the threaded sleeve 31, and the right outer wall of the threaded block 27 is fixedly connected to a protruding rod 32, and the upper and lower outer walls of the protruding rod 32 are fixedly connected to leak-proof rubber rings 33.

[0035] When the temperature of the low-temperature medium 20 inside the temperature conducting cylinder 23 rises, the threaded block 27 can be removed from the threaded sleeve 31 by rotating the handle 28 counterclockwise. Then, after the temperature conducting cylinder 23 is removed from the fixed block 21, the temperature conducting cylinder 23 is erected to pour out the low-temperature medium 20. After pouring out, the low-temperature medium 20 with a lower temperature is replaced into the temperature conducting cylinder 23, and the protruding rod 32 is inserted into the threaded sleeve 31. The handle 28 is rotated clockwise to screw the threaded block 27 and the threaded sleeve 31 together. At this time, the leak-proof cover 29 and the leak-proof rubber ring 33 can prevent the low-temperature medium 20 from leaking.

[0036] like Figure 1 As shown, the right end outer wall of the fixed frame 3 is fixedly connected to the base 1, the front end outer wall of the base 1 is internally transmission-connected to the cabinet door 2, the left end outer wall of the fixed frame 3 is fixedly connected to the support frame 5 to limit the position of the raw material roller 6, and a fixed frame 9 is arranged on the right side of the guide frame a4.

[0037] The corresponding working components inside the base 1 can be repaired by opening the cabinet door 2 , and the support frame 5 is provided with corresponding clamping grooves to limit the position of the raw material roller 6 .

[0038] like Figure 1As shown, the interior of the fixed frame 9 is provided with a driving frame 8 fixedly connected to the hot press 11 to drive the hot press 11 to move up and down, the interior of the fixed frame 9 is fixedly connected to the bottom plate 10, the right side of the fixed frame 9 is provided with a guide frame b12, the interiors of the guide frames a4 and b12 are both provided with guide rods 24, the upper end outer wall of the base 1 is fixedly connected with a tension roller group 14 near the upper end outer wall, and the inner part of the right end outer wall of the base 1 is provided with a movable groove 18.

[0039] The driving frame 8 can drive the heat press 11 to move up and down. When moving down, the connecting belt on the bottom plate 10 is heat-sealed. When moving up, the heat sealing on the bottom plate 10 is completed and the roll bag moves to the right. After moving out, the tension of the roll bag will be increased by the tension roller group 14, so that it can be smoother during subsequent rewinding, avoiding the loosening of the roll bag after rewinding.

[0040] like Figure 1 As shown, a movable machine rod 19 is arranged inside the movable groove 18, and a fixed machine rod 17 is arranged inside the movable groove 18 to limit the position of the positioning rod 16. A driver 15 is fixedly connected between the rear end outer wall of the fixed machine rod 17 and the base 1 to drive the positioning rod 16 to rotate, and the internal transmission of the fixed frame 3 is connected to the guide roller 7.

[0041] After the movable machine rod 19 moves forward, the winding roller of the roll bag can be fixed on the positioning rod 16, and then the movable machine rod 19 moves backward to fix the winding roller for a second time, and drives the positioning rod 16 through the driver 15 to make the winding roller rotate to complete the winding operation of the roll bag.

[0042] The implementation principle of this embodiment is as follows: during the production process of the roll bag, the roll bag is fixed on the raw material roller 6 and guided to the guide rod 24 to contact the temperature conducting cylinder 23, and the roll bag is cooled by the low-temperature medium 20 inside the temperature conducting cylinder 23, and then guided to the heat press 11. After the heat press 11 moves downward to fit the roll bag for heat sealing, it is introduced into the cutting mechanism 13 to leave tear holes on the roll bag, and after passing through the tension roller group 14, it is wound on the winding roller fixed by the fixed machine rod 17 and the movable machine rod 19, and the driver 15 will drive the positioning rod 16 to rotate the winding roller to wind up the manufactured roll bag.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
