Description

Technical Field

[0001] This utility model belongs to the field of tray sliding technology, and more specifically, it relates to a drying oven tray sliding structure. Background Technology

[0002] In the actual application of drying ovens, after the material is introduced into the tray, a sliding structure is usually used to achieve smooth entry and exit of the tray, positioning and unloading of the material. At present, drying oven trays mostly use ball bearing guides, slider guides and other transmission sliding structures to realize the feeding and discharging operation.

[0003] For example, existing application number CN201920385473.6 discloses a sliding structure for a drying oven tray. The drying oven includes a box body and a side-opening door. Multiple trays are provided inside the box body. Smooth grooves corresponding to the trays are provided on two opposite inner walls of the box body. Sliding structures that cooperate with the smooth grooves are provided on both sides of the trays. A vertical sliding groove is provided on the side of the box body near the door, communicating with the ends of all the smooth grooves. A platform groove is connected to the other side of the vertical sliding groove opposite to the smooth grooves. A support block for the trays is provided below the smooth grooves. This utility model has the advantages of reducing equipment footprint, reducing operator workload, avoiding material contamination, and good integration with upstream and downstream processes. Furthermore, this utility model is easy to operate.

[0004] Based on the above, when the material is fed into the pallet, if the material exceeds the pallet's load-bearing capacity, it will easily aggravate the wear of the guide rail. When the material is unevenly distributed on the upper part of the pallet, it will not only affect the drying effect and uniformity of the material, but also easily aggravate the wear of one side of the guide rail due to the uneven load of the pallet, causing the pallet to shift or jam, resulting in mechanical failure or safety accidents. This poses a safety hazard and also affects the operational stability of the equipment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a sliding structure for a drying oven tray. This structure solves the problem that, during the process of feeding materials onto the tray, when the material exceeds the tray's load-bearing capacity, it easily exacerbates the wear of the guide rails. Furthermore, when the material distribution at the top of the tray is uneven, it not only affects the drying effect and uniformity of the material but also easily leads to uneven load on the tray, causing unilateral wear of the guide rails, resulting in tray displacement or jamming, potentially causing mechanical failures or safety accidents. This poses safety hazards and also affects the operational stability of the equipment.

[0006] The purpose and function of this utility model's sliding structure for a drying oven tray are achieved through the following specific technical means:

[0007] A drying oven tray sliding structure includes a drying oven body, limiting guide rails, and an anti-detachment auxiliary mechanism. Two sets of limiting guide rails are symmetrically and fixedly connected to the inner side of the drying oven body. A carrying tray is slidably mounted on the upper end of the inner side of each limiting guide rail. Multiple elastic positioning frames are evenly arranged on the left and right sides of the bottom end face of the carrying tray. Rollers are rotatably mounted on the inner end face of each elastic positioning frame. A connecting support shaft is coaxially and fixedly connected to the inner end face of each roller. A positioning support cylinder is elastically connected to the upper end of each elastic positioning frame. The upper end of the positioning support cylinder is fixedly connected to the bottom end face of the carrying tray. An automatic monitoring mechanism is provided between the rollers and the positioning support cylinder. The anti-detachment auxiliary mechanism is located between the carrying tray and the limiting guide rails.

[0008] Furthermore, the automatic monitoring mechanism includes: auxiliary bearings, there are multiple auxiliary bearings, the multiple auxiliary bearings are respectively arranged on the inner side of the lower end of multiple elastic positioning frames, and the outer ring of the auxiliary bearing is fixedly connected to the elastic positioning frame.

[0009] Furthermore, the inner ring of the auxiliary bearing is fixedly connected with a plurality of positioning protrusions in a circumferential array on the inner side of the bearing.

[0010] Multiple positioning grooves are provided on the outer side of the connecting support shaft at the alignment position with the positioning protrusion.

[0011] Furthermore, a positioning seat is fixedly connected to the outer side of the bottom end face of the positioning support cylinder.

[0012] Furthermore, the automatic monitoring mechanism includes: a monitoring auxiliary frame, wherein there are multiple monitoring auxiliary frames, and the multiple monitoring auxiliary frames are respectively hinged to the outer side of the lower end of multiple positioning seats.

[0013] Furthermore, the monitoring auxiliary frame and the positioning seat on the same side are connected by a spiral elastic element hinge.

[0014] Furthermore, the automatic monitoring mechanism also includes: multiple warning brackets, which are coaxially fixedly connected to the outside of multiple connecting support shafts.

[0015] Furthermore, the outer end of the monitoring auxiliary frame adopts a large arc transition; multiple grooves are evenly arranged on the outer side of the warning bracket; and the outer sides of the multiple grooves all use an arc transition.

[0016] Furthermore, the anti-detachment auxiliary mechanism includes: a resistance-increasing frame and an elastic support. There are two sets of resistance-increasing frames, which are fixedly connected to the left and right sides of the bottom end face of the support tray. An assisting inclined plate is fixedly connected to the front end of the resistance-increasing frame. There are two sets of elastic supports, which are elastically arranged on the front side of the bottom end face of the support tray. A force-bearing inclined plate is fixedly connected to the rear end of the elastic support.

[0017] Furthermore, the anti-hair loss auxiliary mechanism also includes: a guide cylinder, which has two sets, and the two sets of guide cylinders are respectively arranged on the outside of the two sets of elastic supports. The outer end of the guide cylinder is fixedly connected to the main body of the drying box; an extrusion column is elastically connected to the inner end face of the guide cylinder; the extrusion column on the same side is fixedly connected to the elastic support.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention enables automatic monitoring of the load on the carrying tray and the material arrangement on the upper part of the carrying tray. When the material is overloaded or the carrying tray is unbalanced, it automatically emits an audible warning to the operator. This greatly reduces the wear of the limit guide rail and avoids the phenomenon of the carrying tray shifting or jamming due to one-sided wear of the limit guide rail caused by unbalanced load. It improves the safety of the drying oven, the stability of the equipment operation, and the drying effect on the material, and further enhances the working efficiency of this structure in practical applications.

[0020] When this utility model is in use, it increases the sliding resistance when the carrying pallet is about to detach from the limiting guide rail to alert the operator that the carrying pallet is about to detach from the limiting guide rail, thus preventing accidental slippage when the carrying pallet is dragged outward. This improves the operational safety when transferring materials and further enhances the effectiveness of this structure in practical applications. Attached Figure Description
