[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference below Figure 1-Figure 4 The circulating transport heating and curing furnace according to the embodiment of the utility model is described.

[0034] like Figure 1-Figure 4 As shown, the circulating transport heating curing furnace includes a frame 100, a curing furnace box 110, a circulating transport mechanism 300 and a transport mold 200. The equipment is set up in the curing area of ​​the production line. The curing furnace box 110 is set up on the frame 100. At least one set of hot air curing mechanisms 120 is arranged on the top of the curing furnace box 110. A feed port 130 is arranged on one side of the curing furnace box 110, and a discharge port 140 is arranged on the other side. The transport mold 200 carries the product and circulates on the production line. It enters the circulating transport mechanism 300 in the curing furnace box 110 from the feed port 130. During the conveying process of the circulating transport mechanism 300, the product is heated and cured in the curing furnace box 110. The transport mold 200 is finally output from the discharge port 140 and returns to the production line to enter the next process.

[0035] The number of hot air curing mechanisms 120 is set according to the heating area of ​​the curing furnace box 110. The hot air curing mechanisms 120 are evenly distributed in the curing furnace box 110 to ensure that the temperature of each area is relatively balanced. The hot air curing mechanism 120 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0036] Specifically, the circulating transport mechanism 300 is arranged in the curing furnace box 110, and the feeding end and the discharging end of the circulating transport mechanism 300 are respectively located at the feeding port 130 and the discharging port 140 of the curing furnace box 110. A plurality of transport molds 200 are arranged and transported on the circulating transport mechanism 300, and the transport molds 200 clamp the products and flow along the production line. The clamping part structure of the transport mold 200 is adaptively adjusted according to the structure of different products. It should be understood that, without departing from the basic concept of the present utility model, the flexible transformation of the clamping structure of the transport mold 200 should be regarded as within the protection scope defined by the present utility model.

[0037] Among them, Figure 2-Figure 4 As shown, the circulating transport mechanism 300 is arranged in an S shape in the curing furnace box 110, and the transport mold 200 is transported back and forth in the circulating transport mechanism 300. Specifically, the S-shaped arrangement of the circulating transport mechanism 300 is set in a winding manner in the curing furnace box 110. By extending the path of the circulating transport mechanism 300 in the curing furnace box 110, the heating time of the transport mold 200 in the curing furnace box 110 is extended. Unlike the prior art products that reduce the transportation speed or stand still waiting for heating in the curing furnace, the circulating transport heating curing furnace of this embodiment does not need to adjust the flow speed of the production line, ensuring the conveying rate of the production line while fully heating and curing the product, which not only improves the working efficiency of the production line but also improves the final quality of the product.

[0038] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the cyclic transport includes a straight track 310 and a corner track 320 . The straight track 310 extends from one side of the curing furnace box 110 to the other side. Both ends of the straight track 310 are connected to the two corner tracks 320 respectively.

[0039] Specifically, the linear track 310 adopts a multi-section structure, and can be arranged with a corresponding length of linear track 310 according to the width of the curing furnace box 110 and the distance between the feed port 130 and the discharge port 140, without the need to produce separately for different lengths, thus saving construction costs. The cross-sectional structure of the linear track 310 and the corner track 320 is the same.

[0040] Furthermore, if Figure 2-Figure 4 As shown, the corner track 320 is a 90-degree corner structure, and the adjacent straight tracks 310 are spliced ​​at a 180-degree corner through two corner tracks 320. Specifically, the corner track 320 adopts a 90-degree corner structure, which can easily adjust the angle and direction of the track according to different paths, improve the reuse rate of the corner tracks 320 of the same specification, and reduce the construction cost.

[0041] In some embodiments of the present invention, Figure 2-Figure 4As shown, the tops of the linear rail 310 and the corner rail 320 are recessed inward to provide a limiting groove 301, and the limiting groove 301 is along the extension direction of the linear rail 310 and the corner rail 320. The transport mold 200 moves along the preset track of the circular transport mechanism 300 under the limiting action of the limiting groove 301.

[0042] Specifically, the limiting groove 301 can not only limit the lateral displacement of the transport mold 200 on the track transportation, but also be used as a sliding groove for the transport mold 200 to be alternately transported between the two linear tracks 310. The transport mold 200 slides into the corner track 320 at the end of the linear track 310, and slides into the adjacent linear track 310 along the limiting groove 301 under the action of inertia force and continues to be transported.

[0043] In some embodiments of the present invention, Figure 2-Figure 4 As shown, a double-speed transport component is arranged in the linear track 310, and the double-speed transport component includes a driving mechanism (not shown in the drawings) and a conveying chain 332. The length of the conveying chain 332 matches the length of the linear track 310. The driving mechanism is connected to the conveying chain 332 for transmission. The transport mold 200 is mounted on the conveying chain 332 on both sides of the linear track 310 for transportation.

[0044] Specifically, the double-speed transport assembly is arranged in the guide rails on both sides of the linear track 310, and the transport mold 200 is driven to move by the double-speed transport assembly working synchronously. The driving mechanism adopts a servo motor, and the driving mechanism adjusts the conveying speed of the conveying chain 332 to increase the moving speed of the transport mold 200. When the transport mold 200 is separated from the conveying chain 332 on the linear track 310, the transport mold 200 still has a terminal speed. At this time, the transport mold 200 slides along the limit groove 301 of the corner track 320 under the action of inertia force and enters the next linear track 310, contacts the conveying chain 332 in the next linear track 310 and continues to move.

[0045] Furthermore, if Figure 2-Figure 4 As shown, the conveying chain 332 is provided with a transmission part 332a and a support part 332b, the transmission part 332a is arranged on the inner side of the linear track 310 and is connected to the driving mechanism, the support part 332b is connected to the side wall of the transmission part 332a and extends along the middle part of the linear track 310, and the bottom of the transport mold 200 is in contact with the support part 332b and moves synchronously with the support part 332b.

[0046] Specifically, the transmission part 332a adopts a belt structure, connected to the output shaft of the driving mechanism, and the two ends of the transmission part 332a are tensioned by two guide wheels. The support part 332b extends from the side wall of the transmission part 332a, and the support parts 332b of the two side tracks of the linear track 310 are arranged facing each other. The support parts 332b on both sides are respectively in contact with the two sides of the bottom of the transport mold 200 and drive the transport mold 200 to move along the direction of the limit groove 301.

[0047] Furthermore, if Figure 2-Figure 4 As shown, the support parts 332b are provided in multiple groups, arranged side by side on the side wall of the transmission part 332a, and the transmission part 332a and the support parts 332b move synchronously. Specifically, the circumference of the support parts 332b is equal to the circumference of the transmission part 332a, and the support parts 332b are arranged to form a chain structure.

[0048] Furthermore, if Figure 2-Figure 4 As shown, the spacing between the support parts 332b on both sides of the linear track 310 is smaller than the width of the limiting groove 301, and the bottom of the transport mold 200 contacts the support parts 332b when it is placed on the limiting groove 301. Specifically, when the transport mold 200 is placed on the circular transport mechanism 300, both sides of the transport mold 200 are mounted in the limiting groove 301, and the bottom contacts the support parts 332b, and the transmission chain rotates to drive the transport mold 200 to move along the extension direction of the track.

[0049] In some embodiments of the present invention, Figure 2-Figure 4 As shown, a support assembly 340 is disposed at the bottom of the circulating transport mechanism 300 , and the support assembly 340 is used to support the bottom of the circulating transport mechanism 300 so that it is spaced apart from the bottom of the curing furnace box 110 .

[0050] Specifically, the support assembly 340 can realize the overall setting of the circulating transport mechanism 300 off the ground, so that the transport mold 200 on the track is closer to the middle height of the curing furnace box 110 and is heated more evenly.

[0051] In some embodiments of the present invention, Figure 2 As shown, the straight track 310 and the corner track 320 can be detachably connected in sections, so as to facilitate the disassembly, assembly and transportation of the circulating transport mechanism 300.
