Description

Technical Field

[0001] This utility model relates to the field of workpiece drying technology, specifically a drying and heat preservation conveyor. Background Technology

[0002] A drying and heat-insulating conveyor line is a commonly used piece of equipment that dries workpieces via a conveyor belt. The workpieces can be metal or other materials. During operation, the material is dried uniformly through hot air circulation, infrared radiation, or steam heating. Simultaneously, an insulation structure maintains a stable temperature during transport, ensuring product quality.

[0003] If a workpiece has a complex surface texture, it is easy for some areas to remain undried when using a plate chain conveyor for drying, requiring repeated drying processes. Therefore, to save drying time, a drying conveyor with a flipping effect needs to be designed.

[0004] Most existing technologies involve drying and turning over fragmented workpieces, such as tea leaves and grains. Existing technology CN213631356U describes a turning and drying device for wooden handicrafts. It uses a warm air blower to ventilate both sides of the drying chamber, achieving efficient heating. A motor drives the conveyor belt, which moves the turning components, ensuring uniform heating of the handicrafts fixed on them. However, for the workpieces, a fixed clamping method is used, which rotates with the conveyor belt, making it unsuitable for continuous production drying operations.

[0005] To address these issues, we provide a drying and heat-insulating conveyor. Utility Model Content

The slider plate is fitted and slides in the guide groove. A frame plate is installed on the side of the slider plate facing away from the transition groove. A frame groove is opened on the side of the frame plate facing away from the transition groove.

[0021] A transmission plate is installed on the side of the flip plate facing the position plate, and a guide post is installed on the upper end of the transmission plate. The guide post is adapted to slide within the frame groove.

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] Example 1

[0057] See appendix Figure 1-5 This utility model provides a technical solution, specifically including: a drying and heat-insulating conveyor, comprising:

[0058] like Figure 1 and 2 As shown, there is a frame 1, a conveyor belt 2 is installed on the frame 1, and a drive component 3 is installed at the bottom. The drive component 3 is adapted to drive the conveyor belt 2 to run on the frame 1.

[0059] Drying chamber 4 is mounted on frame 1;

[0060] Heat source 5 includes heating box 51 and fixed box 52. Heating box 51 is provided with heating chamber, and fixed box 52 is installed at the bottom. The bottom of fixed box 52 is connected to drying box 4.

[0061] like Figure 3 and 4As shown, the flipping mechanism 6 includes a position plate 61 and a fixed base 62. A transmission component 7 is installed at the output end of the flipping motor 63. Two sets of sliding track plates 64 are provided on the fixed base 62, and flipping plates 65 are installed on the two sets of sliding track plates 64. The flipping plates 65 slide and flip on the sliding track plates 64. The sliding track plates are as follows: Figure 5 As shown, a curved opening 66 is installed at one end of the sliding track plate 64 facing the forward direction of the conveyor belt 2, and the curved opening 66 is adapted to abut against the flip plate 65.

[0062] In this embodiment, a heat source is placed at the top, meaning that external air is introduced and heated through a heating chamber, raising the temperature of the hot air before it is discharged into each fixed chamber and directly into the drying chamber. An internal flipping mechanism is installed to flip the workpieces to be dried. A flipping motor drives a flipping plate through a transmission mechanism, which can be a reciprocating linear structure such as a belt, chain, or rack and pinion. This allows the flipping plate to change from linear sliding to contact at the bend, and then rotate along the curve of the fixed cylinder. Alternatively, one end of the flipping plate can be made into an arc shape to achieve the rotation effect. The drive component is a stepper motor, which, through the installation of a drive sprocket and connection to multiple sets of sprockets, transmits a group of workpieces from the conveyor belt to the flipping mechanism at a constant frequency, thus achieving the rotation effect of the flipping mechanism.

[0063] Example 2

[0064] like Figure 6-10 As shown, this is another embodiment of the present invention. Based on embodiment 1, in order to achieve a stable transmission effect, the conveyor belt 2 is further made into a plate chain conveyor belt 2 for conveying large workpieces, including multiple sets of panels 21 and corner chain belts 22. The corner chain belts ensure the stable transmission effect of multiple sets of sprockets. Multiple sets of transmission rollers are installed in the frame 1, and transmission sprockets 11 are installed at the ends of the transmission rollers. The transmission sprockets 11 are connected to the corner chain belts 22 and are suitable for driving multiple sets of panels 21 to move forward continuously.

[0065] A heating wire 511 is installed inside the heating chamber, and a temperature sensor 512 is also installed inside the heating chamber; an air inlet is installed on the top of the heating chamber 51. Heating with a heating wire is a common heating method, and a temperature detection device also needs to be installed inside the heating chamber to ensure the heating effect and drying temperature effect.

[0066] To ensure the operation of the flipping mechanism, the conveyor belt 2 on the frame 1 is not continuously arranged and is suitable to be separated by the flipping mechanism 6; lateral sprockets 12 are also installed on both sides of the frame 1, and the lateral sprockets 12 are connected to the corner chain belt 22.

[0067] like Figure 9As shown, the position plate 61 is provided with a guide groove 67 and a transition groove 68 on the top, and the transition groove 68 is connected to the guide groove 67. The guide groove is a dovetail groove, which is convenient to restrict the slider plate from sliding out along the slider plate to the frame plate. The length of the transition groove on both sides is less than the length of the guide groove, which restricts the slider plate from sliding out along the axis of the guide groove.

[0068] The drying chamber 4 has an installation slot, and a sealing plate 41 is installed in the installation slot; a fixing plate 42 is installed on the outside of the sealing plate 41, and the fixing plate 42 is connected to the flipping motor 63.

[0070] A transmission belt 72 is installed between the two sets of docking wheels 71. A slider plate 73 is installed on the transmission belt 72 through the transition groove 68 via a mounting fastener. The slider plate 73 is fitted and slides within the guide groove 67. A frame plate 74 is installed on the side of the slider plate 73 facing away from the transition groove 68. A frame groove is opened on the side of the frame plate 74 facing away from the transition groove 68. The fastener can be a screw, a positioning pin, or other rod to fix the transmission belt and the slider plate.

[0071] A transmission plate 69 is mounted on the side of the flip plate 65 facing the position plate 61. A guide post 610 is mounted on the upper end of the transmission plate 69, and the guide post 610 is adapted to slide within the frame groove. The guide post is cylindrical to ensure that at the bend of the flip plate, the cylindrical part is fixed and flipped due to the contact of the curved surface. On the other hand, the rotation of the guide post within the frame groove drives the transmission plate, causing the slider plate to move the guide post within the frame plate.

[0072] The fixed base 62 includes a fixed base plate 611 and a support plate 612. A support frame 9 is installed at the bottom of the fixed base plate 611. Two sets of support plates 612 are provided and fixedly installed on the fixed base plate 611, and sliding track plates 64 are fixedly installed on both sides. One end of the sliding track plate 64 is provided with a bend 66, and the other end is provided with a stop plate 613. The stop plate can be a cylindrical or block-shaped structure, which is required to restrict the flip plate from rotating again.

[0073] The flip plate 65 includes a flip plate body 651 and fixed cylinders 652. Four sets of fixed cylinders 652 are arranged at the four corners of the bottom of the flip plate body 651. The diameter of the fixed cylinders 652 is the same as that of the bending opening 66, and the diameter is not greater than the height of the stop plate 613. The fixed cylinders can be set to have a large diameter at both ends and a small diameter in the middle to restrict them on the sliding track plate.

[0074] The frame groove is vertically arranged and has openings at the top and bottom; the flip motor 63 drives the transmission belt 72 to rotate and the stroke of the slider plate 73 is not greater than the length of the transition groove 68.

The output end of the telescopic output component 83 is connected to the center plate 81 and is suitable for driving the center plate 81 to rise and fall within the flip plate body 651. In this embodiment, the telescopic output component is considered to be inside the oven, therefore, it requires high heat resistance. The following models can be considered:

[0077] TiMOTION TA2P high-temperature type, temperature range: -30℃ to +130℃;
