Description

Technical Field

[0001] This utility model belongs to the field of enamel production technology, and more specifically, it relates to a batch firing device for the production of process enamel. Background Technology

[0002] In the production of enamelware, firing is one of the key processes, as its quality directly determines the color, texture, and durability of the finished product. Currently, the industry commonly uses a conveyor line within a tunnel-type firing furnace for batch firing.

[0003] Existing firing equipment still has some shortcomings in actual use. Traditional support trays or supports are mostly designed with a fixed height and cannot be flexibly adjusted. When firing workpieces of different heights, shorter workpieces may not be heated enough or fired evenly because they are too far from the heating element. Most support structures only provide a placement plane and cannot be flexibly configured and adjusted according to different production needs and processes, which limits the utilization rate and production efficiency of the equipment.

[0004] Therefore, there is an urgent need for a batch firing device that can adapt to workpieces of different specifications, ensure stable and reliable conveying and firing processes, and has good versatility. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a batch firing device for the production of enamelware, which is achieved by the following specific technical means:

[0006] A batch firing apparatus for producing enamelware includes a firing furnace and a roller conveyor. The firing furnace is mounted on the roller conveyor, which is equipped with a support assembly. The support assembly includes a bottom support plate and an upper support plate. The upper support plate is located above the bottom support plate. Two rectangular cylinders are symmetrically mounted on the bottom support plate. Each of the two rectangular cylinders has a groove inside. A sliding rod is slidably mounted in each groove. The top end of each sliding rod is fixedly connected to the bottom end of the upper support plate.

[0007] Each slide bar has several fixing holes evenly spaced on its surface, and each rectangular tube has a bolt that matches the fixing hole for locking the position of the slide bar.

[0008] Furthermore, the upper surfaces of both the bottom support plate and the upper support plate are provided with several strip-shaped holes at equal intervals to increase the friction between the bottom support plate and the workpiece and the roller conveyor rollers.

[0009] Furthermore, mounting grooves are symmetrically provided on both sides of the upper surface of the bottom support plate, and a threaded hole is provided on one side of each mounting groove.

[0010] Furthermore, the bottom end of each rectangular tube is inserted into the mounting groove, and each rectangular tube is fixedly mounted with an ear plate. Each ear plate is inserted with a bolt, and each bolt is threaded into a threaded hole.

[0011] Furthermore, each of the ear plates is located at the upper end of the bottom support plate.

[0012] Furthermore, the fixing holes are equidistantly distributed along the height direction of the slide rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The lifting mechanism, consisting of a bottom support plate, a rectangular cylinder, a slide bar with fixing holes, and an upper support plate, allows the operator to easily adjust the horizontal working surface of the upper support plate to the optimal firing position according to the specific height of the workpiece. The cooperation between the fixing holes and bolts enables precise locking at multiple positions, ensuring structural rigidity during firing and conveying. This allows the device to be adapted to various sizes of enamel workpieces, from low plates and dishes to tall bottles and jars, greatly improving the versatility and utilization of the equipment.

[0015] Second, the automated conveying design of the device reduces manual handling and auxiliary operation, thus lowering labor intensity; the efficient connection between the load-bearing components and the roller conveyor enables continuous batch firing of enamel workpieces, significantly shortening the production cycle and improving overall production efficiency; the rectangular cylinder is firmly fixed by the ear plates, bolts and bottom support plates, and the slide rod is precisely locked to the rectangular cylinder, so that the load-bearing components form a stable overall structure, ensuring stability.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a batch firing device for producing process enamel, including a firing furnace 1 and a roller conveyor 2. The firing furnace 1 is mounted on the roller conveyor 2. The roller conveyor 2 is provided with a bearing component 3. The bearing component 3 includes a bottom support plate 31 and an upper support plate 32. The upper support plate 32 is located above the bottom support plate 31. Two rectangular cylinders 33 are symmetrically installed on the bottom support plate 31. The interior of each rectangular cylinder 33 is provided with a groove 34. A sliding rod 35 is slidably installed in each groove 34. The top end of each sliding rod 35 is fixedly connected to the bottom end of the upper support plate 32.

[0028] Each slide bar 35 has several fixing holes 36 evenly spaced on its surface. Each rectangular tube 33 has a bolt 37 that matches the fixing hole 36, which is used to lock the position of the slide bar 35.

[0029] The upper surfaces of the bottom support plate 31 and the upper support plate 32 are provided with several strip holes 4 at equal intervals to increase the friction between the workpiece and the roller of the roller conveyor 2, prevent slippage, and ensure the stability of the conveying.

[0030] The bottom support plate 31 has symmetrical mounting grooves 31a on both sides of its upper surface. Each mounting groove 31a has a threaded hole 31b on one side, which serves as a positioning and connection, facilitating assembly.

[0031] The bottom end of each rectangular tube 33 is inserted into the mounting groove 31a. Each rectangular tube 33 is fixedly mounted with an ear plate 38. Each ear plate 38 is inserted with a bolt 39. Each bolt 39 is threaded into a threaded hole 31b.

[0032] Each ear plate 38 is located at the top of the bottom support plate 31.

[0033] The fixing holes 36 are evenly distributed along the height direction of the slide bar 35, providing multiple height adjustment positions and improving versatility.

[0034] The working principle of this embodiment:

[0035] Step 1: During assembly, insert the bottom ends of the two rectangular tubes 33 into the pre-set mounting slots 31a on both sides of the upper surface of the bottom support plate 31, and fit the ear plate 38 against the upper end face of the bottom support plate 31. Then, pass the bolt 39 through the ear plate 38, align it with the threaded hole 31b on one side of the mounting slot 31a, screw it in and tighten it. Through the threaded engagement of the bolt 39 and the threaded hole 31b, the rectangular tubes 33 are firmly fixed on the bottom support plate 31, preventing structural loosening during subsequent transportation and firing processes.

[0036] Step 2: For workpieces with low height, the upper support plate 32 can be pushed upwards, causing the slide rod 35 to slide upwards within the groove 34 of the rectangular tube 33, raising the placement height of the workpiece so that the top surface of the workpiece can be evenly fired. For workpieces with high height, the upper support plate 32 is not needed; the bottom support plate 31 is sufficient to support the workpiece, preventing the top of the workpiece from exceeding the effective range of the firing furnace 1 due to excessive height. In specific operation, the operator adjusts the distance between the upper support plate 32 and the bottom support plate 31 according to the actual specifications of the workpiece to be fired. After the height is adjusted to the correct position, the bolt 37 is rotated into the reserved threaded hole of the rectangular tube 33, so that its end is precisely embedded in the corresponding fixing hole 36 on the surface of the slide rod 35. By matching and locking the bolt 37 with the fixing hole 36, the position of the slide rod 35 is fixed, thereby achieving stable positioning of the upper support plate 32. The design of the fixing holes 36 being equidistantly distributed along the height direction of the slide rod 35 provides multiple height adjustment options, further improving the adaptability of the device to workpieces of different specifications.

[0037] Step 3: On the one hand, the strip-shaped hole 4 can increase the friction between the upper support plate 32 and the bottom surface of the enamel workpiece, preventing the workpiece from sliding and shifting due to inertia during the conveying process; on the other hand, the strip-shaped hole 4 can enhance the friction between the bottom support plate 31 and the roller of the roller conveyor 2, ensuring that the bearing component 3 moves synchronously and smoothly with the rotation of the roller of the roller conveyor 2, preventing relative sliding that could lead to deviation in the conveying position; the operator can evenly place the enamel workpiece to be fired on the upper support plate 32.

[0038] Step 4: The roller conveyor 2 starts running, and the rotation of the rollers drives the supporting components 3 and the workpieces placed on them to move at a constant speed, gradually entering the firing furnace 1 set up on the roller conveyor 2. The firing furnace 1 starts the preset firing program to heat and fire the batch of workpieces inside. During this process, the stable structure of the supporting components 3 and the constant speed of the roller conveyor 2 ensure that all workpieces are in the effective heating area of ​​the firing furnace 1, ensuring the consistency of firing temperature and time, and improving the quality uniformity of batch products. After the firing process is completed, the roller conveyor 2 continues to run, transporting the supporting components 3 and the fired enamel workpieces out of the firing furnace 1, completing the entire batch firing process.

Many modifications and variations will be apparent to those skilled in the art.
