[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described clearly and completely below in conjunction with specific embodiments.

[0036] like Figures 1 to 7The tunnel oven shown is for drying medicine bottles, which includes a support box 100, a conveying mechanism 200 provided on the support box 100, and an oven 500 provided on the support box 100;

[0037] The conveying mechanism 200 includes:

[0038] The chain conveyor assembly includes two groups of circulatory chains 201 and a plurality of chain plates 202 spaced between the two groups of chains 201;

[0039] A plurality of mounting plates 300 , wherein the mounting plates 300 are disposed on the chain plates 202 ;

[0040] Several medicine bottle trays 400, four groups of latch assemblies 403 are symmetrically arranged on both sides of the medicine bottle tray 400, and the four groups of latch assemblies 403 are arranged at the four corners of the medicine bottle tray 400, and the pin blocks 403-4 of the latch assemblies 403 are retractably arranged on the medicine bottle tray 400, and the mounting plate 300 is provided with latch holes 301 corresponding to the pin blocks 403-4, and the pin blocks 403-4 extend out and pass through the latch holes 301 to install the medicine bottle tray 400 on the chain plate 202; press the pin blocks 403-4 to retract them to remove the medicine bottle tray 400; three medicine bottle accommodating slots 401 are provided on the medicine bottle tray 400 for placing medicine bottles 600.

[0041] In this embodiment, with the synchronous circulation of the two groups of chains 201, the mounting plate 300 and the medicine bottle tray 400 on the chain plate 2202 enter the oven 500 one by one to dry the medicine bottles 600. The dried medicine bottles 600 enter the next workstation along with the chain conveying assembly.

[0042] See also Figure 7The latch assembly 403 also includes a latch slider 403-1, a limiting column 403-2 set on one side of the latch slider 403-1 and a compression spring 403-3 sleeved on the limiting column 403-2, and the pin block 403-4 is set on the other side of the latch slider 403-1; a latch receiving hole 402 is opened on the medicine bottle tray 400 corresponding to the latch slider 403-1, and the latch slider 403-1 is slidably set in the latch receiving hole The latch block 403-4 is inserted into the latch hole 402; the two ends of the compression spring 403-3 respectively abut against the ends of the latch slider 403-1 and the latch receiving hole 402. A latch cover plate 405 is detachably provided at the opening of the latch receiving hole 402 to limit the sliding movement of the latch slider 403-1. The latch cover plate 405 has a cover plate through hole corresponding to the pin block 403-4. The compression spring 403-3 is used to drive the latch slider 403-1 to slide toward the latch cover plate 405. A cover plate groove is provided at the opening of the latch receiving hole 402, and the latch cover plate 405 is embedded in the cover plate groove.

[0043] See also Figures 2 to 6 The pin block 403-4 is in the shape of a rectangular parallelepiped, the cross section of the latch hole 301 is in the shape of a rectangle, the two vertical sides of the pin block 403-4 abut against the two vertical sides of the latch hole 301, and the upper end of the pin block 403-4 abuts against the upper end of the latch hole 301. Figure 6 Two pop-up blocks 404 are symmetrically disposed at the bottom of the vial tray 400. These pop-up blocks 404 are retractably mounted on the vial tray 400. When extended, these pop-up blocks 404 abut against the mounting plate 300, thereby causing the vial tray 400 to move upward and tighten the upper ends of the pin blocks 403-4 against the upper ends of the latch holes 301. The retraction principle of the pop-up blocks 404 in this embodiment is the same as that of the insert blocks 403-4.

[0044] See also Figure 4 and Figure 5 , a through-hole chamfer 302 is provided on the inner side of the upper end of the latch through-hole 301. When the pin block 403-4 is retracted, the medicine bottle tray 400 rises under the drive of the pop-up top block 404, causing the pin block 403-4 to slide upward along the through-hole chamfer 302, thereby assisting the retraction of the pin block 403-4 to increase the disassembly efficiency of the medicine bottle tray 400. Preferably, a gap is provided between the two sides of the medicine bottle tray 400 and the side walls of the mounting plate 300. After the two pin blocks 403-4 at one end of the medicine bottle tray 400 are retracted, the one end of the medicine bottle tray 400 is quickly tilted up under the drive of the pop-up top block 404, which facilitates the operator to disassemble and install, and avoids the phenomenon that the pin blocks 403-4 at both ends must be retracted at the same time to disassemble the medicine bottle tray 400.

[0045] Combine Figure 3 In the content, a plurality of chain plate through holes are opened on the chain plate 202 of this embodiment, and countersunk holes corresponding to the chain plate through holes are opened on the bottom plate of the mounting plate 300 for passing bolt assemblies to fix the mounting plate 300 and the chain plate 202 in connection.
