[0002] The wrapping machine uses stretch film as packaging material to package the items stacked on the pallet as a whole. It wraps the film online by rotating the machine and wrapping the pallet and the goods forward. When the pallet is moving, it moves from the front conveyor to the rear conveyor. Between leaving the front conveyor and moving to the rear conveyor, the front and rear ends of the pallet are suspended for a period of time, which may cause the pallet to pause or change in movement speed, thus affecting normal production. Summary of the invention

[0003] In view of this, the purpose of the utility model is to propose a pallet transition machine and its winding device to solve the problem that the front and rear ends of the pallet are suspended for a period of time between leaving the front conveyor and moving to the rear conveyor, which may cause the pallet to pause or change in movement speed.

[0004] Based on the above purpose, the utility model provides a pallet transition machine, including a track plate, and also includes: a moving part, a support plate, a support plate, a rotating arm and a driving part, wherein:

[0005] Two track plates are symmetrically arranged, each track plate has a through-groove track, and the height of one end of the through-groove track is higher than the other end;

[0006] Rollers are provided on both sides of the moving member, and the rollers are located in the through-slot track;

[0007] The support plate is arranged on the moving member;

[0008] The support plate is fixedly arranged at one end of the support plate;

[0009] One end of the rotating arm is hinged to the supporting plate, and the other end is transmission-connected to the driving part;

[0010] The driving part can drive the support plate to move through the rotating arm, and when the roller moves from the lower end to the higher end of the through-slot track, the support plate can support the tray.

[0011] Optionally, the driving unit includes a fixing plate fixedly disposed between the two track plates, an electric cylinder is mounted on the fixing plate, and one end of a telescopic rod of the electric cylinder is hinged to the rotating arm.

[0012] Optionally, the cross-section of the support plate is "L"-shaped.

[0013] Optionally, the moving member includes two symmetrically arranged moving plates, a connecting rod is provided between the two moving plates, and the support plate is fixedly arranged on the telescopic connecting rod.

[0014] Based on the same invention, the present invention also provides a winding device, including: a front conveyor, a rear conveyor, a horizontal winding machine and any of the above-mentioned pallet transition machines, wherein:

[0015] The pallet transition machines are provided with two, and the two pallet transition machines are respectively arranged in the middle of the front conveyor and the rear conveyor;

[0016] The horizontal wrapping machine is arranged between the front conveyor and the rear conveyor.

[0017] The pallet transition machine is installed in the middle of the front conveyor and the rear conveyor respectively when in use. At the beginning, the rollers of the front conveyor are located at the lower end of the through-slot track. At this time, the height of the pallet is lower than the top of the front conveyor and the rear conveyor, so it will not affect the transportation of the pallet by the front conveyor and the rear conveyor. The rollers of the rear conveyor are located at the high end of the through-slot track. When the front end of the pallet is about to leave the front conveyor, the pallet on the rear conveyor will drag the front end of the pallet, so that the pallet and the pallet move at the same time. When the front end of the pallet moves to the rear conveyor, the rear conveyor The rollers on the conveyor move to the lower end of the through-slot track, causing the pallet on the rear conveyor to separate from the front end of the pallet. When the rear end of the pallet is about to leave the front conveyor, the pallet transition machine on the front conveyor drives the support plate to move through the drive unit. When the rollers move from the lower end to the higher end of the through-slot track, the pallet can support the pallet, so that the suspended end of the pallet is supported and moves with the pallet. When the pallet is completely moved to the rear conveyor, the drive unit on the front conveyor drives the pallet to move in the opposite direction, causing the pallet to separate from the pallet.

[0018] From the above, it can be seen that the pallet transition machine can ensure that the suspended end of the pallet is always supported when the pallet leaves the front conveyor and moves to the rear conveyor, thereby avoiding situations that cause the pallet to pause or change in movement speed.

[0027] like Figure 1-Figure 4 As shown, a pallet transition machine includes a track plate 5, a moving part 2, a support plate 7, a support plate 6, a rotating arm 4 and a driving part, wherein:

[0028] Two track plates 5 are symmetrically arranged, and each track plate 5 has a through-groove track, and one end of the through-groove track is higher than the other end;

[0029] Rollers 8 are provided on both sides of the moving member 2, and the rollers 8 are located in the through groove track;

[0030] The support plate 7 is arranged on the moving member 2;

[0031] The support plate 6 is fixedly arranged at one end of the support plate 7;

[0032] One end of the rotating arm 4 is hinged to the supporting plate 7, and the other end is transmission-connected to the driving part;

[0033] The driving unit can drive the support plate 7 to move via the rotating arm 4 , and when the roller 8 moves from the lower end to the higher end of the through-slot track, the support plate 6 can support the tray 9 .

[0034] When in use, the pallet transition machine is installed in the middle of the front conveyor 10 and the rear conveyor 11 respectively. At the beginning, the roller 8 at the front conveyor 10 is located at the lower end of the through-slot track. At this time, the height of the pallet 6 is lower than the top of the front conveyor 10 and the rear conveyor 11, so it will not affect the transportation of the pallet 9 by the front conveyor 10 and the rear conveyor 11. The roller 8 of the rear conveyor 11 is located at the high end of the through-slot track. When the front end of the pallet 9 is about to leave the front conveyor 10, the pallet 6 on the rear conveyor 11 drags the front end of the pallet 9, so that the pallet 6 and the pallet 9 move at the same time. When the front end of the pallet 9 moves to the rear conveyor 11, the pallet 6 At this time, the roller 8 on the rear conveyor 11 moves to the lower end of the through-slot track, so that the support plate 6 on the rear conveyor 11 is separated from the front end of the pallet 9. When the rear end of the pallet 9 is about to leave the front conveyor 10, the pallet transition machine on the front conveyor 10 drives the support plate 7 to move through the drive unit. When the roller 8 moves from the lower end to the high end of the through-slot track, the pallet 6 can support the pallet 9, so that the suspended end of the pallet 9 is supported and moves with the pallet 9. When the pallet 9 is completely moved to the rear conveyor 11, the drive unit on the front conveyor 10 drives the pallet 6 to move in the opposite direction, so that the pallet 6 is separated from the pallet 9.

[0035] From the above, it can be seen that the pallet transition machine can ensure that the suspended end of the pallet 9 is always supported when the pallet 9 leaves the front conveyor 10 and moves to the rear conveyor 11, thereby avoiding situations in which the pallet 9 stops or the movement speed changes.

[0036] In some embodiments, the driving unit includes a fixing plate 1 fixedly disposed between the two track plates 5 , an electric cylinder 3 is mounted on the fixing plate 1 , and one end of a telescopic rod of the electric cylinder 3 is hinged to the rotating arm 4 .

[0039] In some embodiments, the moving member 2 includes two symmetrically arranged moving plates, a connecting rod is provided between the two moving plates, and the support plate 7 is fixedly arranged on the telescopic connecting rod.

[0040] like Figure 4 As shown, in order to further implement the present invention, the present invention also provides a wrapping device, comprising: a front conveyor 10, a rear conveyor 11, a horizontal wrapping machine 12, and any of the above-mentioned pallet transition machines, wherein:

[0041] The pallet transition machines are provided with two, and the two pallet transition machines are respectively arranged in the middle of the front conveyor 10 and the rear conveyor 11;

[0042] The horizontal wrapping machine 12 is disposed between the front conveyor 10 and the rear conveyor 11 .

[0043] During operation, the pallet 9 is transported by the front conveyor 10 and the rear conveyor 11. When the pallet 9 moves to the horizontal wrapping machine 12, the goods on the pallet 9 are wrapped and packed by the horizontal wrapping machine 12. At the beginning, the roller 8 at the front conveyor 10 is located at the lower end of the through-slot track. At this time, the height of the support plate 6 is lower than the top of the front conveyor 10 and the rear conveyor 11, so it will not affect the transportation of the pallet 9 by the front conveyor 10 and the rear conveyor 11. The roller 8 of the rear conveyor 11 is located at the high end of the through-slot track. When the front end of the pallet 9 is about to leave the front conveyor 10, the support plate 6 on the rear conveyor 11 drags the front end of the pallet 9, so that the support plate 6 and the pallet 9 move at the same time. After the front end of the tray 9 moves to the rear conveyor 11, the roller 8 on the rear conveyor 11 moves to the lower end of the through-slot track, so that the pallet 6 on the rear conveyor 11 is separated from the front end of the tray 9. When the rear end of the tray 9 is about to leave the front conveyor 10, the tray transition machine on the front conveyor 10 drives the support plate 7 to move through the drive unit. When the roller 8 moves from the lower end to the high end of the through-slot track, the pallet 6 can support the tray 9, so that the suspended end of the tray 9 is supported and moves with the tray 9. When the tray 9 is completely moved to the rear conveyor 11, the drive unit on the front conveyor 10 drives the pallet 6 to move in the opposite direction, so that the pallet 6 is separated from the tray 9.
