Description

Technical Field

[0001] The present application relates to the technical field of coating preheating devices, and in particular to a novel preheating box. Background Art

[0002] After coating, the material needs to enter the oven for drying in time, and the material needs to be preheated between coating and entering the oven. Preheating can conveniently connect the coating and oven processes, while reducing the drying time required for the material and improving the coating adhesion to improve product quality.

[0003] Depending on the process and equipment, the material's film-moving route will change. For example, if the material is relatively low after coating, the material needs to enter the oven on a slope. The conventional rectangular flip-top preheating oven cannot meet the film-moving route requirements, resulting in poor preheating effects. At the same time, the hinges are easily worn or even stuck due to the tilt of the center of gravity during the flipping process, affecting life and safety. Utility Model Content

[0004] In order to improve the problem of insufficient adaptability of the rectangular flip-top preheating box in the related art, the utility model provides a new preheating box.

[0005] A novel preheating box comprises a supporting mechanism, a preheating box body and a driving mechanism for driving the preheating box body to open and close, wherein the preheating box body comprises a lower box body and an upper box body which are arranged on the supporting mechanism, wherein the lower box body and the upper box body are arranged obliquely, and a side of the upper box body close to the lower box body has an arc-shaped wind chamber, wherein the arc-shaped wind chamber is provided with a plurality of wind nozzle structures; the driving mechanism connects the upper box body and the lower box body, and the upper box body can rise or fall in a vertical direction relative to the lower box body.

[0006] Furthermore, upper fixed seats are provided on both sides of the upper box body, and lower fixed seats are provided on both sides of the lower box body. The driving mechanism includes a driving cylinder provided on both sides of the upper fixed seat, the piston end of the driving cylinder faces the lower box body, and the piston end of the driving cylinder is connected to the lower fixed seat.

[0007] Furthermore, the axis of the driving cylinder coincides with a plumb line on a corresponding side of the upper box body.

[0008] Furthermore, the driving mechanism also includes a plurality of guide rods, the lower box body is provided with a fixed block, the guide rods are arranged on the fixed block and face the upper box body; the upper box body is provided with a guide seat, and the guide rods are slidably connected to the guide seat.

[0009] Furthermore, the guide rod is provided with a through hole along its circumferential direction, and a limiting pin for limiting the guide seat is arranged in the through hole of the guide rod.

[0010] Furthermore, the wind nozzle structure includes a curved panel arranged on one side of the curved air chamber close to the lower box body and a plurality of wind nozzle pieces snap-fitted and installed on the curved panel, and the plurality of wind nozzle pieces are arranged at intervals along the length direction of the curved panel.

[0011] Furthermore, both ends of the air nozzle member are provided with buckle members, and buckle parts for matching with the buckle members are arranged on both sides of the arc-shaped air chamber, and the buckle member and the buckle parts are detachably connected.

[0012] Furthermore, the support mechanism includes a first support seat and a second support seat, and the first support seat and the second support seat are provided with a connecting beam.

[0013] The utility model has the following advantages:

[0014] 1. The utility model provides a new type of preheating box, which can better adapt to and preheat the materials that climb the slope and move along the film by arranging an inclined lower box body and an upper box body, and arranging an arc-shaped wind chamber in the upper box body, thereby improving the preheating effect of the materials. At the same time, a driving mechanism is used to drive the upper box body to rise or fall in the vertical direction relative to the lower box body instead of opening and closing the flip-type structure, which can avoid the life and safety problems of the device caused by the center of gravity offset of the flip-type structure, thereby improving the problem of poor adaptability of the preheating box in the related technology.

[0015] 2. The utility model provides a new preheating box, in which the driving cylinder coincides with the plumb line on the corresponding side of the upper box body, and cooperates with the guide rod, so that the driving cylinder can stably drive the upper box body and the lower box body to open and close. At the same time, the upper box body is limited by the limit pin after opening and closing, which can avoid the sudden drop of the upper box body when the cylinder is suddenly cut off, thereby increasing the working stability, safety and service life of the new preheating box.

[0016] 3. A new type of preheating box of the utility model has an air nozzle structure adopting a curved panel and a detachable air nozzle part. The problem of air leakage during the preheating process can be avoided by adapting the curved panel to the curved air chamber.

[0031] Reference Figure 1 and Figure 2 A novel preheating box includes a supporting mechanism 1, a preheating box body 2 and a driving mechanism 3. The supporting mechanism 1 supports the preheating box body 2 and the driving mechanism 3, the preheating box body 2 preheats the incoming materials, and the driving mechanism 3 is used to drive the preheating box body 2 to open and close.

[0032] Specifically, the support mechanism 1 includes a first support seat 11 and a second support seat 12, and the first support seat 11 and the second support seat 12 are arranged below the preheating box 2. The first support seat 11 includes a first support column, and a first bottom plate is fixedly connected to the side of the first support column away from the preheating box 2, and the first bottom plate is used to increase the contact area with the ground. Similar to the first support seat 11, the second support seat 12 includes a second support column, and a second bottom plate is fixedly connected to the side of the second support column away from the preheating box 2, and the second bottom plate is used to increase the contact area with the ground.

[0033] At the same time, there is a gap between the first support seat 11 and the second support seat 12, and a connecting crossbeam 13 is arranged between the first support seat 11 and the second support seat 12. The connecting crossbeam 13 is arranged horizontally, and a rectangular forklift hole is arranged below the second support seat 12. By setting the connecting crossbeam 13, on the one hand, the structural connection strength of the support mechanism 1 can be increased, and on the other hand, it can cooperate with the forklift hole to facilitate forklift transportation.

[0034] The preheating box 2 includes a lower box 21 and an upper box 22 arranged on the support mechanism 1. Specifically, the lower box 21 is fixedly connected to the support mechanism 1, and the lower box 21 has an inclined section and a horizontal section. The inclined section of the lower box 21 is inclined and fixedly connected to the second support seat 12, and the horizontal section of the lower box 21 is horizontally arranged and fixedly connected to the first support seat 11. A plurality of rotating rollers are arranged in the lower box 21, and the material passes through the rotating rollers of the inclined section to climb and preheat, and then enters the drying process through the horizontal section.

[0035] Correspondingly, the upper box body 22 is tilted above the lower box body 21, and the shape of the upper box body 22 is adapted to the shape of the lower box body 21. The upper box body 22 has an arc-shaped wind chamber 221 on one side close to the lower box body 21. The arc-shaped wind chamber 221 extends from one side of the length direction of the upper box body 22 to the other side of the length direction of the upper box body 22. The arc-shaped wind chamber 221 has a plurality of wind nozzle structures 23 for preheating the material on one side close to the lower box body 21.

[0036] Reference Figure 3 and Figure 4The air nozzle structure 23 includes a soft curved panel 231 arranged on the side of the curved air chamber 221 close to the lower box 21 and a plurality of air nozzle pieces 232 snap-fitted and installed on the curved panel 231. The curved panel 231 is fitted and installed on the curved air chamber 221 and connects the curved air chamber 221 and the air nozzle piece 232. The shape of the curved panel 231 is adapted to the curved air chamber 221. By setting the curved panel 231 to adapt and connect the curved air chamber 221 and the air nozzle piece 232, air leakage during the preheating process is avoided, thereby improving the preheating quality of the material. It can be understood that the curved panel 231 can be installed in a manner of splicing multiple sub-panels to form an integral body, can be installed after integral molding, or can be installed in a manner of multiple distributed corresponding to respective areas, as long as it can adapt to the curved air chamber 221 and the air nozzle piece 232.

[0037] Several nozzle pieces 232 are arranged at intervals along the length direction of the curved panel 231. In this embodiment, in order to achieve quick and convenient disassembly and installation, the two ends of the nozzle piece 232 have buckle pieces 2321, and the two sides of the curved air chamber 221 are provided with buckle parts 2211 for matching the buckle pieces 2321. The buckle pieces 2321 are detachably connected to the buckle parts 2211. More specifically, the buckle piece 2321 includes a pull ring 23211 rotatably connected to the nozzle piece 232 and a hooking rod 23212 provided on the pull ring 23211, and the buckle part 2211 has a corresponding hooking groove. When installing the nozzle piece 232, the nozzle piece 232 is buckled on the curved panel 231, the hooking rod 23212 at one end of the nozzle piece 232 is hooked in the hooking groove, and the pull ring 23211 is rotated to keep the hooking rod 23212 straightened for limiting, so that one end of the nozzle piece 232 is installed in the curved air chamber 221, and the other end is installed in the same way to complete the installation of the nozzle piece 232. When disassembling, it is only necessary to rotate the pull ring 23211 to make the hooking rod 23212 disengage from the hooking groove of the buckle part 2211 to disengage the nozzle piece 232 from the curved air chamber 221.

[0038] The driving mechanism 3 is connected to the upper box body 22 and the lower box body 21. Under the drive of the driving mechanism 3, the upper box body 22 can rise or fall in the vertical direction relative to the lower box body 21. Specifically, in order to install the driving mechanism 3, upper fixing seats 222 are respectively provided on both sides of the upper box body 22, and lower fixing seats 211 are respectively provided on both sides of the lower box body 21. The driving mechanism 3 includes a driving cylinder 31 provided on both sides of the upper fixing seat 222. The driving cylinder 31 is provided with a control valve and a control handle for controlling the opening and closing of the driving cylinder 31. The piston end of the driving cylinder 31 faces the lower box body 21, and the piston end of the driving cylinder 31 is connected to the lower fixing seat 211. At the same time, the axis of the driving cylinder 31 coincides with the plumb line on the corresponding side of the upper box body 22. By arranging the driving cylinder 31 in this way, the upper box body 22 can be stably raised and lowered in the vertical direction.

[0039] In addition, the driving mechanism 3 further includes a plurality of guide rods 32. In the present embodiment, there are four guide rods 32, which are chrome-plated rods. The four guide rods 32 are respectively located on both sides of the preheating box 2 and adjacent to the driving cylinder 31. In order to install the guide rods 32, the lower box 21 is provided with a fixing block 212, and the guide rods 32 are arranged on the fixing block 212 and face the upper box 22. Correspondingly, the upper box 22 is provided with a guide seat 223, and the guide rods 32 are slidably connected to the guide seat 223. In order to increase the contact area, the guide seat 223 is provided with a guide sleeve, and the guide rods 32 are slidably connected to the guide seat 223. By such a configuration, when the upper box 22 rises or falls, the guide rods 32 can guide the upper box 22, thereby improving the operation stability of the upper box 22.

[0040] Reference Figure 2 and Figure 5 It is worth mentioning that, in order to improve the safety of the upper box body 22 during operation, the guide rod 32 is provided with a through hole along its circumferential direction, and a limit pin 33 for limiting the guide seat 223 is provided in the through hole of the guide rod 32. When the upper box body 22 and the lower box body 21 are in a closed state, the limit pin 33 is installed and placed in the through hole of the guide rod 32; when the upper box body 22 is to be opened, the limit pin 33 is first pulled out from the through hole of the guide rod 32, and then the upper box body 22 is driven to rise. When the upper box body 22 rises to its position, the limit pin 33 is re-installed into the through hole of the guide rod 32, and the limit pin 33 blocks the upper box body 22 from descending. By setting the limit pin 33 to limit the upper box body 22, a safety accident caused by the upper box body 22 falling due to sudden leakage of the cylinder due to a fault can be avoided.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
