The two deviation rectifying planes formed on the support can clamp a packaging bag roll inwards from the two sides in the rolling direction of the packaging bag when the packaging bag is rolled, and the distance between the two deviation rectifying planes clamping the packaging bag roll is the same as the bag width of the packaging bag, so that axial deviation of the packaging bag in the process of winding the packaging bag into the roll is effectively avoided, and the packaging bag roll is prevented from being damaged. And therefore, the flatness of the two side faces of the packaging bag roll is improved, and the damage probability in the later transportation and storage process is reduced.

Description

Technical Field

[0001] The utility model relates to packaging bag processing and production machinery and equipment, in particular to a deviation correcting device in the process of packaging bag rolling. Background Art

[0002] After the packaging bag is produced, it is usually necessary to roll it for subsequent transportation and storage. In the process of rolling the packaging bag, the packaging bag is wound around the reel one circle at a time through the rotation of the reel, and then the roll packaging is completed.

[0003] Patent CN220097989U discloses a commonly used packaging bag rolling device. When in use, the rolling roller is sleeved on the support rod, and then the rolling roller is placed on the support plate. At this time, the fixed plate and the support plate are pushed upward to a suitable height by the cylinder. Then the double-headed motor drives the screw to rotate, and the screw will drive the slider to move toward each other in the slide groove, so that the slider drives the vertical plate to move toward each other, so that the vertical plate drives the clamp seat to move toward each other, and then both ends of the support rod are inserted into the groove on the clamp seat, and the clamp seat can limit the rolling roller. When in use, the motor is driven to rotate the pulley 2, and the pulley 2 will drive the pulley 1 to rotate through the belt, so that the pulley 1 drives the corresponding clamp seat to rotate through the rotating shaft, and then the clamp seat can drive the support rod and the rolling roller to rotate, which can facilitate the disassembly and installation of the rolling roller, thereby effectively improving the efficiency of the installation of the rolling roller and effectively reducing the labor intensity of the workers.

[0004] Although the above-mentioned prior art can complete the rolling of packaging bags, the packaging bags will deviate to both sides during the rolling process due to mechanical vibration, which will cause the two sides of the packaging bag roll to be uneven. During transportation, when the packaging bag roll needs to be placed vertically, the edge of the packaging bag extending from the lower side will be squeezed and deformed under the action of gravity, or even damaged, which will make the roll of packaging bags unusable. It can be seen that the flat side of the packaging bag roll is very important for the preservation of the packaging bag roll. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a deviation correction device in the process of rolling up a packaging bag. The utility model can effectively improve the flatness of the side surface of the packaging bag roll.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A deviation correction device for a packaging bag during rolling comprises a fixing frame on which two deviation correction planes parallel to each other are formed. The two deviation correction planes clamp the packaging bag roll inward from both sides along the axial direction of the packaging bag roll, and the distance between the two deviation correction planes when clamping the packaging bag roll is the same as the bag width of the packaging bag.

[0008] As a further solution of the utility model: a guide rail is installed on the fixed frame; two correcting rollers extending toward the packaging bag reel are rotatably installed on the guide rail, and the two correcting rollers are clamped on both sides of the packaging bag roll so that when the packaging bag reel is wound, the roller surfaces are respectively attached to the two side surfaces of the packaging bag roll along the radial direction of the packaging bag reel; the vertical plane where the roller surface of the correcting roller contacts the side surface of the packaging bag roll constitutes the correcting plane.

[0009] As a further solution of the utility model: a sliding sleeve is slidably installed on the guide rail, a rotating shaft is fixedly installed on the sliding sleeve, the deviation correction roller is coaxially rotatably sleeved on the rotating shaft, and a locking piece for locking the position of the sliding sleeve on the guide rail is also installed on the sliding sleeve.

[0010] As a further solution of the utility model: the locking member includes a threaded hole formed on the sliding sleeve, and a locking bolt threadedly connected in the threaded hole and having a front end that can abut against the guide rail in a tightened state.

[0011] As a further solution of the utility model: two positioning rings are coaxially fixedly installed on the rotating shaft, the deviation correction roller is clamped between the two positioning rings, and the axis of the rotating shaft and the axis of the packaging bag reel intersect each other perpendicularly.

[0012] As a further solution of the utility model: the guide rail is in a rectangular parallelepiped shape, the length direction of the guide rail is parallel to the axial direction of the packaging bag roll, and the sleeve hole of the sliding sleeve is a rectangular through hole matched with the guide rail.

[0013] As a further solution of the utility model: a rotary handle for screwing the locking bolt is installed at the top end of the locking bolt.

[0014] As a further solution of the utility model: the bracket is fixedly installed beside the packaging bag reel.

[0015] As a further solution of the utility model: the deviation correction roller is made of stainless steel.

[0016] As a further solution of the utility model: the length of the guide rail is greater than the length of the packaging bag reel

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The two deflection-correcting planes formed on the bracket of the utility model can clamp the packaging bag roll inward from both sides along the axial direction of the packaging bag roll when the packaging bag is rolled up, and the distance between the two deflection-correcting planes when clamping the packaging bag roll is the same as the bag width of the packaging bag, thereby effectively avoiding axial deviation of the packaging bag during the process of winding it into a roll, thereby improving the flatness of the two sides of the packaging bag roll and reducing the probability of damage during the later transportation and storage process.

[0019] 2. The utility model uses two correcting rollers clamped on both sides of the packaging bag roll to correct the deviation of the packaging bag. At the same time, the rotation axis of the correcting roller is parallel to the axis of the packaging bag reel, so that the correcting roller rotates synchronously with the packaging bag roll during the correction process, reducing the friction damage caused by the side of the packaging bag and the correcting roller.

[0020] 3. The utility model adopts a sliding sleeve method to adjust the distance between the two deviation-correcting rollers, thereby adapting to packaging bags of different bag widths and improving the application range of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] See also Figure 1-2 In an embodiment of the utility model, a deviation correction device in the process of rolling up a packaging bag mainly includes a bracket 1. The bracket 1 is fixedly installed on the side of the packaging bag reel, and the bracket 1 is a steel structure. A steel guide rail 11 is installed on the bracket 1, and the guide rail 11 is a rectangular parallelepiped, and the length direction of the guide rail 11 is parallel to the axial direction of the packaging bag roll 4. A steel sliding sleeve 2 is movably sleeved on the guide rail 11, and the sleeve hole of the sliding sleeve 2 is a rectangular parallelepiped through hole that matches the guide rail 11.

[0026] A locking member 21 is also installed on the sliding sleeve 2 to lock the position of the sliding sleeve 2 on the guide rail 11. The locking member 21 includes a threaded hole 211 provided on the sliding sleeve 2, and a locking bolt 212 threadedly connected in the threaded hole 211 and having a front end that can abut against the guide rail 11 in a tightened state. Multiple threaded holes 211 can be provided, so that the locking force of the locking sliding sleeve 2 can be further improved through the abutting effect of multiple locking bolts 212, and the sliding sleeve 2 can be firmly fixed on the guide rail 11. In order to improve the convenience of tightening the locking bolt 212, a rotating handle 213 is coaxially fixedly installed on the top of the locking bolt 212.

[0027] A steel rotating shaft 3 is fixedly mounted on the sliding sleeve 2, and two positioning rings 31 are coaxially fixedly mounted on the rotating shaft 3. A steel deflection correction roller 32 is sandwiched between the two positioning rings 31, and the length of the deflection correction roller 32 is the same as the distance between the two positioning rings 31. The axis of the rotating shaft 3 and the axis of the packaging bag reel intersect each other perpendicularly, so that the deflection correction roller 32 rotates synchronously with the packaging bag reel 4 during the deflection correction process, reducing the friction damage caused by the side of the packaging bag and the deflection correction roller 32. The length of the deflection correction roller 32 is greater than the radius of the packaging bag reel 4 after winding, and when working, the front end of the deflection correction roller 32 is infinitely close to the outer side of the packaging bag reel, so that the deflection correction is performed from the beginning.

[0028] When in use, first adjust the positions of the two correcting rollers 32 according to the width of the packaging bag and the position of the packaging bag reel, then lock the two correcting rollers 32, and then start the winding work. After the winding is completed, the two correcting rollers 32 are unlocked to facilitate the removal of the packaging bag roll 4, and then the next winding work is carried out.
