DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example:

[0023] like Figure 1 The simple fixing device for incoming Tray materials shown in the figure comprises a pallet 1, a support plate 2 and a side limit block 3; two pallets 1 are arranged at intervals, and the support plate 2 is connected to the pallet 1 so that the two pallets 1 and the support plate 2 form a Tray loading area 4, and the side limit block 3 is installed on the pallet 1, and the side limit blocks 3 on the two pallets 1 are arranged relatively, and the side limit blocks 3 are embedded in the Tray loading area 4. Limiting grooves are set on both sides of the Tray. When using this device, the Tray enters the Tray loading area 4 and falls on the pallet 1, and the side limit blocks 3 just fit into the limiting grooves of the Tray, thereby fixing the Tray to enter the next process. This device is different from the prior art that uses a motor or a cylinder to fix the Tray. It is designed with a purely mechanical structure, and the overall structure is simple. It does not require external related conditions such as electricity or gas. It is easy to operate and low in cost.

[0024] like Figure 2 and Figure 3 As shown, the side limit block 3 includes a base 5 and a limit seat 6 connected to each other; the base 5 is installed on the pallet 1, and the opposite surfaces of the two limit seats 6 are first guide surfaces 7, at least part of which is embedded in the tray loading area 4, and the two side surfaces adjacent to the first guide surface 7 are second guide surfaces 8, and the second guide surfaces are inclined surfaces 8. The side limit block 3 is installed on the pallet 1 through the base 5, and the first guide surface 7 and the second guide surface 8 are provided, which can play a guiding role when the tray falls into the loading area, so that the limit seat 6 can be accurately inserted into the limit groove of the tray.

[0025] The first guide surface 7 includes a first inclined surface 9 and a first vertical surface 10, the first inclined surface 9 and the first vertical surface 10 are arranged up and down, and the bottom end of the first inclined surface 9 and the first vertical surface 10 are embedded in the tray loading area. The first inclined surface 9 plays a guiding role when the tray falls, and the first vertical surface 10 is embedded in the limiting groove of the tray to prevent the tray from falling.

[0026] like Figure 1 and Figure 4 As shown, it also includes a first stopper 11, which is installed at one end of the pallet 1, and the first stoppers 11 on the two pallets 1 are arranged opposite to each other, and the support plate 2 is connected to the other end of the pallet 1. The two pallets 1, the two first stoppers 11 and the support plate 2 cooperate to form a tray loading area, and fix the four sides of the tray to prevent it from falling off. It also includes a cushion block 17; the cushion block 17 is located at the other end of the pallet 1 and is connected to the support plate 2. By setting the cushion block 17, the stability of the tray is improved to prevent it from shaking during transportation.

[0027] The surface opposite to the first stopper 11 and the support plate 2 is a third guide surface 12, and the third guide surface 12 includes a second inclined surface 13 and a second vertical surface 14, the second inclined surface 13 and the second vertical surface 14 are arranged up and down, and the second vertical surface 14 contacts the Tray. The second inclined surface 13 plays a guiding role when the Tray falls, and the second vertical surface 14 contacts the Tray to play a fixing role.

[0028] like Figure 1 As shown, the guide wheel group is also included; the guide wheel group is installed on the tray 1 and is located on both sides of the tray loading area 4. The guide wheel group includes a mounting groove 15 and a plurality of guide wheels 16. The mounting groove 15 is installed on the tray 1, and the opening of the mounting groove 15 faces the tray loading area 4. The plurality of guide wheels 16 are sequentially arranged in the mounting groove along the entry direction of the tray. The guide wheels 16 play a guiding role when the tray enters the tray loading area 4.

[0029] When used specifically:

[0030] When the tray is loaded with materials, it enters the tray loading area at a height higher than the first stopper and the side limit block, and then enters above the tray through the guide wheels on both sides of the tray. After reaching the position, the tray descends and reaches the tray surface along the first guide surface of the side limit block. At this time, the tray is restricted from moving by the first stopper and the side limit block, thereby achieving the purpose of fixing the tray.

[0031] The above-mentioned specific implementation modes are preferred embodiments of the present invention and cannot be used to limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the protection scope of the present invention.
