Description

Technical Field

[0001] This utility model relates to the field of automated food packaging production technology, and in particular to a pallet conveying device. Background Technology

[0002] In automated food packaging production lines, plastic or wooden pallets serve as the core carriers for the packaging boxes, circulating between processes such as filling, sealing, and palletizing. Current mainstream pallet conveying equipment generally suffers from the following technical defects: food packaging lines need to accommodate various sizes of packaging boxes, resulting in significant differences in pallet dimensions. Traditional conveying devices have fixed inlet structures, requiring machine shutdown and manual replacement of limit blocks or shims when switching between different pallet sizes. Furthermore, because food pallets are generally lightweight and lack edge reinforcement, multiple pallets can easily slip out simultaneously due to vibration when the inlet height exceeds the pallet thickness. Conversely, if the inlet height is less than the pallet thickness or the side clearance is too small, the deformed edge of the pallet may rub against the inlet and become jammed.

As shown, the device includes: a conveying component 100 for conveying pallets 500; a storage frame 200 disposed at the inlet end of the conveying component 100, wherein the pallets 500 to be conveyed are stacked within the storage space formed by the storage frame 200 and the conveying component 100; an inlet 400 is provided between the storage frame 200 and the conveying component 100, the inlet 400 being used to limit the output of a single pallet 500 at a time; and an adjusting component 300 fixed to the storage frame 200 for adjusting the size of the inlet 400. By setting an adjustable inlet 400, the pallets 500 can be conveyed with adaptive separation, reducing the outlet adjustment time to less than three minutes; by using the physical constraint of the inlet 400 to replace the traditional mechanical forced separation, the deformation rate and jamming rate of the pallets 500 are reduced; effectively reducing production line capacity loss and improving production efficiency.

[0019] See Figure 2 and Figure 3 , Figure 3 This is a top view of a pallet 500 conveying device according to an embodiment of this application; Furthermore, in this embodiment, the storage frame 200 includes two side plates 210 and a mounting plate 220.

The side plates 210 provide vertical positioning to prevent the pallet 500 from tipping over, and the mounting plate 220 is used to install the adjustment assembly 300 and the blocking pallet 500.

[0020] See Figure 2 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the adjusting component 300 of a pallet 500 conveying device in an embodiment of this application; Furthermore, in this embodiment, the adjustment component 300 includes a height adjustment unit, which comprises: at least one first slide rail 311, vertically disposed on the mounting plate 220; a first adjustment plate 312, slidably connected to the first slide rail 311; and a first drive unit 320, connected to the first adjustment plate 312. The first drive unit 320 is used to drive the mounting plate 220 to slide up and down to control the height of the feed inlet 400. Precise height control of the feed inlet 400 is achieved through the first drive unit 320, eliminating the technical problem that multiple sheets can easily slide out simultaneously due to vibration of the pallet 500.

[0021] Preferably, the first slide rail 311 has two rails to improve the stability of transmission.

[0022] See Figure 4 Furthermore, in this embodiment, the first drive unit 320 includes: a drive shaft 321 rotatably disposed above the first slide rail 311; a drive gear 322 fixed on the drive shaft 321; a drive chain 323 meshing with the drive gear 322, one end of the drive chain 323 being connected to the first adjusting plate 312; and a drive motor 324, the power output end of which is connected to the drive shaft 321 via a reducer 325. By setting the reducer 325 and the gear chain drive, transmission errors can be effectively reduced, the height of the discharge port can be precisely controlled, and recalibration is not required.

[0023] Preferably, the transmission shaft 321 is provided with two transmission gears 322, and two transmission chains 323 are respectively meshed on the two transmission gears 322, which improves transmission stability and reduces the deformation rate of the first adjusting plate 312; the basic function can still be maintained even if a single chain breaks.

[0024] See Figure 2 and Figure 4 Furthermore, in this embodiment, the adjustment assembly 300 also includes two lateral limiting units 330, which are symmetrically arranged on both sides of the first adjustment plate 312 in the horizontal direction. The height adjustment unit and the two lateral limiting units 330 achieve bidirectional limiting adjustment of the feed inlet 400; simultaneously, when the pallet 500 deviates during transport, the limiting rod 333 can automatically guide and reset, reducing manual intervention.

[0025] See Figure 4Furthermore, in this embodiment, the lateral limiting unit 330 includes: a second slide rail 331, which is laterally fixed to the first adjusting plate 312; a second adjusting plate 332, which is slidably connected to the second slide rail 331; a limiting rod 333, which is vertically connected to the second adjusting plate 332; and a drive cylinder 334, which is fixed to the first adjusting plate 312, and the power output end of the drive cylinder 334 is connected to the second adjusting plate 332.

[0026] Preferably, the second slide rail 331 has two rails, which can improve transmission stability.

[0027] Preferably, a baffle plate 335 is fixed on the limiting rod 333, and the extending direction of the baffle plate 335 is parallel to the conveying direction of the pallet 500. By setting the baffle plate 335 to extend to the bottom surface of the pallet 500, the warping problem caused by insufficient rigidity of the plastic pallet 500 is solved, and the tilting and jamming rate is reduced to zero.

[0028] Preferably, the drive cylinder 334 is a pneumatic cylinder or an electric cylinder, and the extension and retraction direction of the drive cylinder 334 is perpendicular to the conveying direction of the pallet 500.

[0029] Preferably, the transmission component 100 is a transmission roller 110, and the rolling friction coefficient of the transmission roller 110 is 0.01~0.03, which reduces the wear of the pallet 500 compared with chain conveyor.

[0030] As can be seen from the above, the pallet conveying device of this utility model achieves adaptive separation of pallets by setting an adjustable feed inlet, and the adjustment time of the discharge port is shortened to less than three minutes; by replacing the traditional mechanical forced separation with physical constraints of the feed inlet, the deformation rate and jamming rate of the pallets are reduced; effectively reducing the production line capacity loss and improving production efficiency.
